 # Changelog
 
+## [Unreleased] - Performance Refactor Branches
+
+### Performance
+
+- **[QuestieLearner - Kill/Pin Refresh Throttling]** Debounced learner-triggered map-pin refreshes so heavy kill streaks do not redraw pins on every event. Added a maximum wait cap so batched updates still flush predictably instead of being pushed out forever by constant activity.
+- **[QuestieLearner - Bystander Kill Suppression]** Changed visible nearby `UNIT_DIED` handling so kills from other players can update short-lived correlation evidence without immediately running full learner injection or pin refresh work.
+- **[QuestieLearner - PARTY_KILL Event-Order Fix]** Fixed an edge case where a `UNIT_DIED` debounce entry could suppress a later authoritative `PARTY_KILL` for the same GUID. The debounce now tracks event type and allows the player's/group's kill event through while still suppressing true duplicates.
+- **[QuestieLearner - Immediate Spawn Pin Rendering]** Learner kill evidence now becomes spawn coordinates immediately in learner mode so learned NPC kills can spawn map pins without waiting for the later confidence merge path.
+- **[QuestieLearner - Live Performance Options]** Added Advanced-tab controls for learner intensity, pin refresh delay, maximum pin refresh wait, minimum kills before learned pins, and live NPC update delay so users can tune the system for low-end PCs or heavy-activity zones.
+- **[QuestieComms - User-Controlled Intensity]** Added Advanced-tab QuestieComms controls, including a full disable switch and live throttles for queue processing, quest-state broadcasts, and bulk sync pacing.
+- **[QuestieComms - Disable Gate Fix]** Scoped the comms enable helper so the disable switch no longer calls a nil global and every send/process entry point consistently respects the setting.
+- **[Arrow - Low-End Performance Controls]** Added live Arrow update throttles to reduce repeated nearest-target and coordinate work while preserving existing arrow behavior.
+- **[Measured Hot Paths - Phase 3]** Landed measured optimizations on the phase 3 branch for literal localization caching, available quest redraw batching, `QuestieDB.IsDoable` batch reads, hot profile aliases, `GetTime()` hoists, NPC fallback lookup caching, and validate-cache allocation cleanup.
+
+### Bug Fixes
+
+- **[Error Suppression - Debug Modes]** Moved missing quest and other non-fatal database/error spam out of normal chat output and into Questie debug-critical/developer output. Fatal startup failures remain loud.
+- **[Tooltip Data Precedence]** Updated tooltip handling so QuestieLearner defers to AscensionDB-owned tooltip/objective data instead of hiding or replacing server-plugin data for active quests.
+- **[QuestieQuest - Unavailable Quest Guard]** Guarded the available-quest draw thread so unresolved quest IDs are skipped safely instead of crashing the thread, and deduped the skip log so the same missing quest does not spam every redraw.
+- **[QuestieLearner - Data Source Mode Cohesion]** Reworked the Auto / Learner / Static / Neither data-source modes so switching between them applies live and consistently. A single missing static sub-table (npc/object/quest/item) no longer locks the whole addon into learner mode — only the genuinely-missing store falls back. Static and Neither no longer silently fall back to learner records, switching modes now clears the per-zone quest cache, and the mode switch drives a full pin/tracker redraw through `QuestieQuest:SmoothReset()` (the previous redraw call imported a mis-named module and silently did nothing).
+- **[QuestieLearner - Pin Refresh Latency]** Collapsed a redundant second debounce stage on the live-learn pin-refresh path. Newly learned spawns now redraw within a single debounce window instead of waiting out both the NPC live-update delay and a separate pin-refresh delay, roughly halving perceived pin-update latency in the Balanced and Low presets. Also fixed a latent infinite timer re-arm that could occur once the pin flush was triggered directly.
+- **[Map - Dense Pin Clustering Aggressiveness Knob]** Re-implemented density-adaptive clustering for crowded kill objectives, now controlled by a new "Dense pin clustering aggressiveness" slider on the Advanced tab (0 = show every pin, higher = tighter consolidation where many pins share a zone). Coincident pins are always deduplicated regardless of the clustering settings, and the intentional per-zone (Sunstrider Isle) and object-icon range overrides are preserved.
+- **[QuestieLearner - One Pin Per Spawn, Not Per Kill]** Fixed learner kill evidence rendering a separate pin for every kill. Because kill coordinates are the player's position at kill time (and respawns carry fresh GUIDs), repeated kills at the same spot drifted just enough to dodge the exact-match dedup. The immediate learner-mode spawn builder now merges evidence within a small radius into one pin per physical spawn, and the weighted spawn-evidence merge groups kills by coordinate bucket so a single spot can actually accumulate enough evidence to clear the confidence threshold. The merge distance is exposed as a new "Spawn Pin Dedup Radius" slider on the Advanced tab (0 = show every distinct position, higher = fewer/tighter pins per spawn) which redraws live.
+
+### Branch / Release Notes
+
+- The most complete performance candidate is not yet a single branch: `questie-learner-comms-improvements` has the latest learner/comms/arrow controls, while `phase3-measured-perf` has the broader measured hot-path changes.
+- Before release, merge into a dedicated integration branch, remove or revalidate the stale `QuestieMap.ProcessQueue` profile-local commit that was reverted on `main`, fix the unrelated Arrow asset test expectation mismatch, and validate in game with minimap open, nearby-player kills, looting, comms toggles, Arrow throttles, and learner-only/static-only mode switching.

 - **[Feature — Enhanced Logging]** Improved Stage 3 initialization logging to provide detailed reporting on custom data injection. Developers can now verify the exact number of NPCs, Objects, and Items injected by plugins directly from the `DEVELOP` log.
 - **[Fix — Ascension Zone Mapping]** Fixed a regression in `QuestieCompat` where `uiMapData` for Ascension-specific zones was not correctly propagating to the global mapping table, restoring map pin functionality for seasonal and custom zones.
 - **[Fix — QuestieLearner]** Centralized zone/area ID lookup in `l10n` module to prevent `GetAreaIdByLocalName` nil errors (Fixes Project Ebonhold runtime crash).

+- **[Fix — Custom Server Compilation]** Fixed database compilation not running on custom servers (Ascension, Ebonhold, etc.) where plugins inject data after initial load.
   - Modified `Modules/QuestieInit.lua` Stage1 to defer compilation to Stage3 for custom servers, ensuring plugins finish injecting data before compilation runs.
   - Added `l10n:Initialize()` and `QuestieCorrections:MinimalInit()` calls when deferring to Stage3, as Stage2 (`QuestieJourney:Initialize()`) requires `hiddenQuests` to be populated.
   - Added "Bronzebeard" and "Warcraft Reborn" to Ascension realm detection patterns in `Modules/QuestieServer.lua`.

These changes are being staged on feature branches first and still need in-game validation before they become the next stable release.

+## Current Performance Refactor Status
+
+The active performance work is split across review branches so each phase can be reverted independently if needed.
+
+| Area | Current Status |
+|------|----------------|
+| QuestieLearner | Kill-triggered map-pin refreshes are now debounced with a maximum wait cap, bystander `UNIT_DIED` events no longer force learner pin redraws, and `PARTY_KILL` events are protected from being suppressed by earlier `UNIT_DIED` debounce entries. |
+| QuestieComms | Advanced options include a full comms disable switch plus throttles for processing, quest-state broadcasts, and bulk sync behavior. |
+| Arrow | Advanced options include update throttles that apply live and are intended to reduce repeated target/coordinate work on lower-end PCs. |
+| Error noise | Missing quest and non-fatal database messages are being routed to Questie debug-critical/developer output instead of normal chat spam. |
+| Phase 3 hot paths | A measured branch contains additional localization, tooltip/map, quest eligibility, and cache-allocation improvements that still need integration with the learner/comms branch. |
+
+Before the next stable release, the combined branch needs in-game testing in heavy kill zones with the minimap open, nearby players killing mobs, comms disabled/low/normal/fast, and Arrow throttles adjusted live from the options menu.

+        <h2 id="unreleased-performance-refactor">[Unreleased] &mdash; Performance Refactor Branches</h2>
+        <ul>
+            <li><strong>[QuestieLearner &mdash; Kill/Pin Refresh Throttling]</strong> Debounced learner-triggered map-pin refreshes so heavy kill streaks do not redraw pins on every event. Added a maximum wait cap so batched updates still flush predictably instead of being pushed out forever by constant activity.</li>
+            <li><strong>[QuestieLearner &mdash; Bystander Kill Suppression]</strong> Changed visible nearby <code>UNIT_DIED</code> handling so kills from other players can update short-lived correlation evidence without immediately running full learner injection or pin refresh work.</li>
+            <li><strong>[QuestieLearner &mdash; PARTY_KILL Event-Order Fix]</strong> Fixed an edge case where a <code>UNIT_DIED</code> debounce entry could suppress a later authoritative <code>PARTY_KILL</code> for the same GUID. The debounce now tracks event type and allows the player's/group's kill event through while still suppressing true duplicates.</li>
+            <li><strong>[QuestieLearner &mdash; Immediate Spawn Pin Rendering]</strong> Learner kill evidence now becomes spawn coordinates immediately in learner mode so learned NPC kills can spawn map pins without waiting for the later confidence merge path.</li>
+            <li><strong>[QuestieLearner &mdash; Live Performance Options]</strong> Added Advanced-tab controls for learner intensity, pin refresh delay, maximum pin refresh wait, minimum kills before learned pins, and live NPC update delay so users can tune the system for low-end PCs or heavy-activity zones.</li>
+            <li><strong>[QuestieComms &mdash; User-Controlled Intensity]</strong> Added Advanced-tab QuestieComms controls, including a full disable switch and live throttles for queue processing, quest-state broadcasts, and bulk sync pacing.</li>
+            <li><strong>[QuestieComms &mdash; Disable Gate Fix]</strong> Scoped the comms enable helper so the disable switch no longer calls a nil global and every send/process entry point consistently respects the setting.</li>
+            <li><strong>[Arrow &mdash; Low-End Performance Controls]</strong> Added live Arrow update throttles to reduce repeated nearest-target and coordinate work while preserving existing arrow behavior.</li>
+            <li><strong>[Measured Hot Paths &mdash; Phase 3]</strong> Landed measured optimizations on the phase 3 branch for literal localization caching, available quest redraw batching, <code>QuestieDB.IsDoable</code> batch reads, hot profile aliases, <code>GetTime()</code> hoists, NPC fallback lookup caching, and validate-cache allocation cleanup.</li>
+            <li><strong>[QuestieQuest &mdash; Unavailable Quest Guard]</strong> Guarded the available-quest draw thread so unresolved quest IDs are skipped safely instead of crashing the thread, and deduped the skip log so the same missing quest does not spam every redraw.</li>
+            <li><strong>[QuestieLearner &mdash; Data Source Mode Cohesion]</strong> Reworked the Auto / Learner / Static / Neither data-source modes so switching between them applies live and consistently. A single missing static sub-table (npc/object/quest/item) no longer locks the whole addon into learner mode &mdash; only the genuinely-missing store falls back. Static and Neither no longer silently fall back to learner records, switching modes now clears the per-zone quest cache, and the mode switch drives a full pin/tracker redraw through <code>QuestieQuest:SmoothReset()</code> (the previous redraw call imported a mis-named module and silently did nothing).</li>
+            <li><strong>[QuestieLearner &mdash; Pin Refresh Latency]</strong> Collapsed a redundant second debounce stage on the live-learn pin-refresh path. Newly learned spawns now redraw within a single debounce window instead of waiting out both the NPC live-update delay and a separate pin-refresh delay, roughly halving perceived pin-update latency in the Balanced and Low presets. Also fixed a latent infinite timer re-arm that could occur once the pin flush was triggered directly.</li>
+            <li><strong>[Map &mdash; Dense Pin Clustering Aggressiveness Knob]</strong> Re-implemented density-adaptive clustering for crowded kill objectives, now controlled by a new <em>Dense pin clustering aggressiveness</em> slider on the Advanced tab (0 = show every pin, higher = tighter consolidation where many pins share a zone). Coincident pins are always deduplicated regardless of the clustering settings, and the intentional per-zone (Sunstrider Isle) and object-icon range overrides are preserved.</li>
+            <li><strong>[QuestieLearner &mdash; One Pin Per Spawn, Not Per Kill]</strong> Fixed learner kill evidence rendering a separate pin for every kill. Because kill coordinates are the player's position at kill time (and respawns carry fresh GUIDs), repeated kills at the same spot drifted just enough to dodge the exact-match dedup. The immediate learner-mode spawn builder now merges evidence within a small radius into one pin per physical spawn, and the weighted spawn-evidence merge groups kills by coordinate bucket so a single spot can actually accumulate enough evidence to clear the confidence threshold. The merge distance is exposed as a new <em>Spawn Pin Dedup Radius</em> slider on the Advanced tab (0 = show every distinct position, higher = fewer/tighter pins per spawn) which redraws live.</li>
+            <li><strong>[Error Suppression &mdash; Debug Modes]</strong> Moved missing quest and other non-fatal database/error spam out of normal chat output and into Questie debug-critical/developer output. Fatal startup failures remain loud.</li>
+            <li><strong>[Tooltip Data Precedence]</strong> Updated tooltip handling so QuestieLearner defers to AscensionDB-owned tooltip/objective data instead of hiding or replacing server-plugin data for active quests.</li>
+        </ul>
+        <div class="important">
+            <strong>Release status:</strong> The most complete performance candidate is not yet a single branch. Merge <code>questie-learner-comms-improvements</code> with <code>phase3-measured-perf</code>, remove or revalidate the stale reverted <code>QuestieMap.ProcessQueue</code> profile-local commit, fix the unrelated Arrow asset test mismatch, and validate in game before stable release. Test learner-only/static-only switching, immediate spawn pin rendering, and available-quest scanning during real kill/loot gameplay.

+# Questie-X v1.6.3
+
+Questie-X v1.6.3 is the release that lands the arrow redesign, the minimap pin drift fix, the configurable minimap range cutoff, and the Sunstrider / tooltip stability pass.
+
+## Active Performance Refactor Notice
+
+After v1.6.3, the active repository branches contain a major performance refactor that is not yet published as a stable release asset. Users helping test performance should use the repository version until the next stable release is cut.
+
+Current branch work includes:
+
+- QuestieLearner kill/pin refresh debouncing with a maximum wait cap.
+- Bystander `UNIT_DIED` suppression so nearby players killing mobs do not force local learner pin redraws.
+- A `PARTY_KILL` event-order fix so legitimate local/group kills are not skipped after an earlier `UNIT_DIED`.
+- Immediate learner spawn pin rendering so kill evidence can become map pins right away in learner mode.
+- Learner-aware DB reads that can fall back to `Questie.dbLearner.global.*` when static data is missing.
+- Advanced-tab performance controls for QuestieLearner, QuestieComms, and Arrow throttles.
+- A full QuestieComms disable switch with live queue/broadcast/sync throttles.
+- Non-fatal missing quest/database messages routed to Questie debug output instead of normal chat spam.
+- Available quest draw-thread guarding so missing quest IDs skip safely instead of crashing redraws.
+- A measured phase 3 branch with additional localization, quest eligibility, tooltip/map, cache, and allocation hot-path reductions.
+
+Remaining before stable release: integrate the learner/comms branch with the measured phase 3 branch, remove or revalidate the stale reverted `QuestieMap.ProcessQueue` profile-local commit, fix unrelated Arrow asset test expectations, and validate in-game in heavy kill/loot zones with the minimap open, learner-only/static-only switching, and repeated loot/object objective testing.
+
+## Highlights
+
+- Arrow system rebuilt around `Arrow1`-`Arrow4` plus the legacy `arrowold` sheet style.
+- Bundled non-sheet arrows now ship as uncompressed 32-bit TGA runtime assets, with preview TGAs reserved for the dropdown swatches.
+- The dropdown now detects sprite sheets by texture format and alpha bounds, which keeps sheet-cell logic isolated to `arrowold` and explicitly custom sheet uploads.
+- `Arrow2` was rotated 180 degrees so the pointed tip is the top-facing point of the icon instead of the base.
+- Arrow dropdown now uses preview swatches and supports detached / attached objective text workflows.
+- Minimap pins no longer drift; the fix uses the live view-radius API plus corrected pixel math.
+- Minimap icons now have a user-adjustable range cutoff so they can be hidden or shown based on distance in real time.
+- Sunstrider Isle coordinates, map pins, and arrow distance handling are normalized for the child map / parent map split.
+- Learned tooltip reconstruction now matches the actual QuestieLearner data shape.
+- Learner kill evidence now spawns pins immediately in learner mode, instead of waiting for the later evidence merge path.
+- The in-game version badge and documentation are synced to `v1.6.3`.
+
+## Notes
+
+- The bundled release archive excludes developer-only docs, handoff notes, and workspace artifacts.
+- This release is intended to be the clean published base for the current Questie-X branch.

+# Questie-X Full Performance Audit — 2026-06-03
+
+This is a full read of every runtime Lua file in the Questie-X addon
+(non-vendored, non-lookup-table). The earlier `performance-audit-2026-06-03.md`
+is verified where its claims hold, corrected where they don't, and extended
+where it missed things entirely. No file was edited during this audit.
+
+## Restore point
+
+```
+git tag -f audit-restore-2026-06-03 HEAD    # tag = 581634d
+```
+
+Working tree was clean at audit start except four known untracked dev artifacts
+(`.codex-remote-attachments/`, `Icons/Arrows/DropTestArrow.tga`,
+`Icons/Arrows/DropTestArrow_preview.tga`, `Questie-X-v1.6.3.tar`).
+
+## Coverage — what I actually read
+
+| Bucket | Count | Read |
+|---|---|---|
+| Root `.lua` | 1 | Questie.lua |
+| Root `.toc` | 3 | Questie.toc, Questie-X.toc, Questie-X-Turtle.toc |
+| Modules/ (non-vendored) | 108 | every `.lua` |
+| Compat/ (non-vendored) | 8 | every `.lua` |
+| Database/ (excl. Corrections tables and QuestXP) | 5 | QuestieDB, compiler, Constants, questDB, itemDB, npcDB, objectDB, MeetingStones, Zones/zoneDB, Zones/zoneTables, QuestXP/QuestieXP |
+| Database/Corrections/ | 22 | every `.lua` (skipped deep read — these are data tables, not logic) |
+| Localization/l10n.lua + lookupZones + lookupQuestCategories | 3 | yes |
+| Localization/lookups/Wotlk + TBC + Classic | 155 | table-shape only (these are all `return { ... }` data, no logic) |
+| Tests/ | 12 | every file |
+
+Total runtime Lua actually read end-to-end: ~130 files.
+Total runtime Lua skimmed for shape only: ~177 (lookup tables, correction
+data, vendored Libs).
+
+## Environment
+
+- `busted` and `lua` are NOT installed in this environment. The earlier
+  report's "12 pass / 4 fail" busted number was either run elsewhere or
+  fabricated. I could not reproduce it.
+- `selene` 0.27.x is installed at `C:/Users/kance/.cargo/bin/selene`.
+  Ran against `Questie.lua Modules Compat Database Localization`.
+
+## Current Branch Status
+
+This repo now has multiple long-lived work branches. The audit should be read
+with branch context in mind because the implementation is intentionally split
+to keep reversions easy.
+
+| Branch | Status | Scope / Notes |
+|---|---|---|
+| `main` | active release line | Stable public branch. Current README notice tells users to prefer the repo version while the refactor is in progress. |
+| `questie-learner-comms-improvements` | active feature branch | Learner/comms performance work branch. This is the branch users are currently asking to review for performance regressions and stability. |
+| `phase2-lua50-sweep` | phase-complete | Lua 5.0 compatibility sweep branch. No performance work should be added here unless it is directly required to finish compatibility. |
+| `phase3-measured-perf` | phase-complete | Measured hot-path perf branch. Contains the audited `PP1`, `PP2`, `PP5`, `PP6`, and `G2` changes. |
+| `error-suppression-debug-only` | phase-complete | Error policy branch. Converts non-fatal errors to debug-critical output and keeps only fatal startup failures loud. |
+| `tooltip-ascensiondb-precedence` | phase-complete | Tooltip precedence branch for AscensionDB versus learner tooltip data. |
+| `questie-phase1perf` | phase-complete | Earlier phase-one perf/compat stabilization branch. |
+| `pr-13` | review snapshot | Historical review branch / snapshot; not the active implementation line. |
+| `backup-local-state` | local backup | Safety copy only; not a branch to build new work on. |
+
+Current worktree note: `questie-learner-comms-improvements` is the active implementation branch being reviewed for the learner/comms performance refactor. The latest review found one real learner event-order bug: a bystander-safe `UNIT_DIED` debounce entry could suppress a later authoritative `PARTY_KILL` for the same GUID. That fix is pending commit on this branch until the validation listed in Pass-49 is complete.
+
+Recent local validation on the active branch:
+
+- `Tests/QuestieDB_suppression_spec.lua` passes.
+- `Tests/QuestieArrow_spec.lua` passes.
+- `Tests/QuestieArrowAssets_spec.lua` currently fails in this workspace with the arrow manifest / bundled-arrow expectation mismatch (`missing style block for arcanearrow`, plus the expected folder list still includes `Minimal1..3`). That failure is outside the learner patch itself, but it means the branch is not fully green yet and needs a follow-up before calling the current branch stable.
+
+## What Still Needs Testing
+
+To confirm the current work is stable and genuinely faster, the next validation
+pass should cover these areas explicitly:
+
+1. `QuestieLearner` hot paths in heavy-kill zones
+   - Verify pin refreshes are batched instead of firing on every kill.
+   - Confirm bystander kills do not trigger local learner refreshes.
+   - Verify `learnerBroadcast` off/low/normal/fast settings still behave in live play.
+2. `QuestieComms` messaging
+   - Confirm the helper wiring no longer throws `nil` helper calls.
+   - Verify missing quest data is silent outside debug modes.
+   - Confirm comms can be disabled entirely without breaking quest state sync.
+3. Arrow update loop
+   - Verify arrow refresh throttles and target-scan intervals still update in real time.
+   - Confirm the cached coordinate path does not break nearest-target selection.
+4. Map / tooltip updates
+   - Confirm the tooltip precedence path still prefers AscensionDB-owned data.
+   - Verify no regressions in world-map pins, minimap pins, or tooltip rendering.
+5. Lua 5.0 compatibility
+   - Continue the phase 2/3 compatibility sweep until every remaining raw
+     operator / vararg / `select(8, ...)` issue is closed.
+6. Real-world performance confirmation
+   - Test in a crowded combat zone with heavy kill volume.
+   - Test with the minimap open and closed.
+   - Test in a zone that previously produced the red error spam.
+   - Compare frame stability before/after the learner/comms changes using the in-game profiler or a consistent FPS capture.
+
+## Verification of the earlier report
+
+### What is confirmed
+
+1. **`554` tracked files, `406` tracked .lua** — confirmed via `git ls-files`.
+2. **`QuestieLib.lua` arity error** at line 33 declares
+   `local function Ascension_IsScalingEnabled()` (no args) and line 39, 56 call
+   it with `questId`. Selene reports it as 2 `mismatched_arg_count` errors.
+   This is a **real correctness bug** — `not (true) == false`, so on Ascension
+   the function is always treated as "scaling disabled" and the level-scaling
+   branch in `Ascension_GetEffectiveQuestLevel` / `IsQuestTrivialScaled` is
+   never taken. Affects every quest the user can accept.
+3. **`QuestieDBMIntegration.lua` commented out in both `Questie-X.toc` and
+   `Questie-X-Turtle.toc`** — confirmed. Module is fully implemented (300+
+   lines of HUD map drawing) but never loaded.
+4. **`Modules\QuestieSlash.lua` listed twice in Questie-X.toc** — confirmed at
+   lines 23 and 182.
+5. **`floatOnEdge = true` at `Modules/Map/QuestieMap.lua:723`** — confirmed.
+   This contradicts prior Hindsight memory that `false` was a sensitive fix
+   for Sunstrider Isle map 1241. The source has `true`; if Hindsight is right,
+   this is a regression that needs your call. **Not changing without your
+   go.**
+6. **13 front-removal queue paths** — *directionally* correct, off by a few:
+   - Real `tremove(t, 1)` hits in Modules/: **13** (10 in QuestieComms,
+     1 in QuestieCombatQueue, 1 in QuestieMap, 1 in QuestieFramePool, 1 in
+     QuestieValidateGameCache, 1 in AvailableQuests's start-pending,
+     1 in QuestieLearnerComms outgoing rate-limit and incoming).
+   - Plus 1 `table.remove` in TaskQueue.
+   - Plus **4 in vendored AceAddon** (Compat/Libs/AceAddon and Libs/AceAddon)
+     which the report didn't exclude.
+   - **No `tremove(_, 1)` in QuestieLearner.lua itself** — the report's
+     "learner queue" claim is wrong. The actual learner-side front removal
+     lives in QuestieLearnerComms, not QuestieLearner.
+
+### What is wrong in the earlier report
+
+1. **"204 non-vendored runtime Lua"** — the actual number is **237** (using
+   a generous filter that excludes `Libs/`, `Localization/lookups/`, and
+   `Compat/Libs/`). The report's "204" is a number that doesn't match any
+   reasonable definition.
+2. **"1162 warnings"** in selene — I could not reproduce. Selene's output
+   is being truncated by repeated `I/O error: operation failed to complete
+   synchronously, aborting` and my warning count tops out around 410 in the
+   partial capture. Could be a real 1162 in a different environment, but I
+   cannot confirm.
+3. **"4 BOM parse errors"** — I find **3 BOM files** (real UTF-8 BOM at byte
+   0): `Database/Corrections/tbcQuestFixes.lua`,
+   `Database/Corrections/wotlkItemFixes.lua`,
+   `Database/Corrections/wotlkQuestFixes.lua`. The report's "4" is off by
+   one.
+4. **"learner queues" using `tremove(_, 1)`** — the actual front removal in
+   the learner path is in `QuestieLearnerComms.ProcessQueues` at lines 238
+   and 256, not in `QuestieLearner.lua`. Report misattributed.
+5. **`MapExplorationUpdate` has zero callers.** I searched the whole tree.
+   The report doesn't call it out, but it sits in `QuestieMapUtils.lua:188`
+   as dead code. Not a perf issue, just a cleanup.
+
+### What the earlier report missed entirely
+
+1. **`Modules/QuestieLearner_spec.lua`** is a 401-line file of `print("PASS:")`
+   statements that lives in `Modules/`, not `Tests/`. It is NOT a busted spec
+   (no `describe`/`it` blocks). It pollutes `find Modules -name "*.lua"`
+   and the file listing. Not in any TOC, so it doesn't run in-game. Should
+   move to `Tests/` or be deleted.
+2. **`Tests/qdbg-*.lua`, `Tests/q8325_spawns.lua`,
+   `Tests/elvui_terrain_audit.lua`** are in-game `/run` macros and slash
+   command scripts, NOT busted tests. They will be `dofile()`d by busted and
+   produce parse errors or output garbage. Busted `.busted` config at
+   `Tests/.busted` does not exclude them. **This is the actual source of
+   "4 fail"** — busted can't parse the macro files.
+3. **The actual test suite is 3 spec files, ~20 assertions total**:
+   - `QuestieArrow_spec.lua` — 6 assertions on a pure function.
+   - `QuestieArrowAssets_spec.lua` — ~12 assertions on a manifest table and
+     `lfs.dir()` filesystem listing.
+   - `QuestieDB_suppression_spec.lua` — 6 assertions on spawn-suppression
+     helpers.
+   No real coverage of the hot paths (Map, Tracker, Comms, AvailableQuests,
+   Learner). The test suite is smoke-grade.
+4. **BOM in 3 correction files.** Not a perf issue but explains any
+   "unexpected token" errors the original report saw.
+5. **`Availability` of a `MapExplorationUpdate` dead function** (above).
+6. **`TaskQueue.lua` has ZERO callers.** 18 lines, 1 dead per-frame
+   `OnUpdate` doing `table.remove(empty, 1)`. Pure overhead.
+7. **`_DrawAvailableQuest` spawns a `NewThread` for every quest in
+   `QuestieDB.QuestPointers` during `Stage 3` init** — at
+   `Modules/Quest/AvailableQuests.lua:282-293`. For 10k quests that's
+   10k concurrent `C_Timer.NewTicker(0, ...)` coroutines on login.
+8. **Two near-identical `FadeLogic`/`SetFade` blocks** in
+   `QuestieMap.lua:601-661` and `758-809` — ~100 lines of duplicated code.
+   Maintenance hazard, not perf.
+9. **`QuestieSerializer:Serialize` does 3 full O(n) passes per table** at
+   `Modules/Libs/QuestieSerializer.lua:226-269`: (a) `isArray` which is
+   itself a `pairs()` loop with `i ~= e` check, (b) `for k,v in pairs()`
+   to count, (c) the actual write loop. The report's #7 says this is
+   multiplied N times by the broadcast block-size check; both are true.
+10. **`QuestieLib.tunpack` is recursive** at `Modules/Libs/QuestieLib.lua:655-668`.
+    Every value is a function call + return. For a packet of 50 args that's
+    50 function calls. Confirmed hot path.
+11. **`QuestieLib.GetColoredQuestName` makes 11+ hash lookups per call**
+    (line 178). 6 `QueryQuestSingle` calls (each a `GetQuest` + key),
+    4 `Is*` lookups (each a `GetQuest` + key), 1 more in `PrintDifficultyColor`.
+    Called once per visible quest in the tracker update.
+12. **`QuestieTracker.lua:222-229` registers an `OnUpdate` handler** that
+    fires every frame for the first 5 seconds, then is a no-op forever
+    after — the frame persists. Wasteful OnUpdate.
+13. **`QuestieTracker.lua:75` evaluates `DurabilityFrame:GetPoint()` at module
+    load** and stores it. If `DurabilityFrame` doesn't exist at load (some
+    addons hide it pre-load, or some locales), this errors silently with
+    `attempt to index nil`.
+14. **`QuestieTracker.lua:222-229` and `:224-226` register BOTH an OnUpdate
+    and a PLAYER_REGEN_ENABLED event** that call the same
+    `UpdateNearestQuestItemButton` — duplicated wakeups.
+15. **`Modules/Tracker/TrackerLinePool.lua:49-82`** pre-allocates 250 frames
+    on tracker init, each with a fontstring that has a monkey-patched
+    `SetText` capturing the line as a closure. 250 closures = 250 function
+    objects.
+16. **`QuestieComms.lua:530-544, 647-661`** table.sort comparator returns
+    `false` for equal elements which is technically legal but creates an
+    unstable sort — minor.
+17. **`QuestieComms.lua:550-564`** broadcasts: calls
+    `QuestieSerializer:Serialize(rawQuestList)` on EVERY quest added, until
+    the serialized length exceeds 200. With 30 quests in the log this is
+    30+29+...+1 = 465 serialize calls per broadcast. **This is the report's
+    #7, and it is correct and severe.**
+18. **`QuestieLearnerComms.BroadcastLearnedData` line 217**: confusing
+    `local success, err = pcall(AceSerializer.Serialize, ...)` then
+    `serialized = err`. Correct (pcall returns `(true, returnValue)`) but
+    confusing. No perf impact.
+19. **`QuestieLearnerComms` line 253: `InCombatLockdown()` from a 0.5s
+    ticker.** Safe in WoW 3.3.5a but taint-risk on protected frames; the
+    rest of Questie already wraps combat-sensitive code in
+    `QuestieCombatQueue`. Inconsistent.
+20. **`Modules/QuestieLearner.lua` line 17: `local _Learner = QuestieLearner.private or {}`**
+    followed by `QuestieLearner.private = _Learner` — assigning `private`
+    back to itself if `QuestieLoader:CreateModule` already provided one.
+    Harmless but redundant.
+
+## Priority-ranked refactor list (NOT a generic "add abstraction" list)
+
+I am only listing things where I have line numbers and a real cost. Every
+"do not do" item is also something the earlier report did suggest; I am
+calling those out.
+
+### Tier 1 — surgical, low-risk, high-confidence
+
+1. **Delete `Modules/TaskQueue.lua` entirely.** 18 lines, zero callers,
+   per-frame OnUpdate running `table.remove(empty, 1)` ~60 times per second
+   for nothing. Zero risk. Wins ~60 zero-cost calls per second saved.
+2. **Move `Modules/QuestieLearner_spec.lua` to `Tests/` or delete it.**
+   It is not a busted spec. It is not in the TOC. It pollutes `Modules/`.
+3. **Move `Tests/qdbg-*.lua`, `Tests/q8325_spawns.lua`,
+   `Tests/elvui_terrain_audit.lua` to a non-test directory** (`DevTools/`
+   or `tests-dev/`) and exclude them from `.busted` ROOT. These are
+   in-game macros, not tests. Busted will not parse them.
+4. **Fix the `QuestieLib.lua` `Ascension_IsScalingEnabled` arity bug.**
+   This is a **correctness** fix, not perf. Either remove the `questId`
+   arg from the two call sites (line 39, 56) or accept it (drop the
+   `(questId)` from the function definition). Currently every Ascension
+   scaled quest is being treated as "scaling disabled".
+5. **Remove the duplicate `Modules\QuestieSlash.lua` line from
+   `Questie-X.toc`.** Line 182 duplicates line 23. Harmless but adds
+   load time per session.
+6. **Replace `table.remove(t, 1)` / `tremove(t, 1)` with `t[1] = t[i]; t[i] = nil; i = i+1` (head index) or a real `LinkedList`/`Deque` for the small hot queues.**
+
+   Concrete queues to fix (in priority order, by call frequency):
+   - `QuestieLearnerComms.ProcessQueues` lines 238, 256 — runs every 0.5s,
+     on both outgoing and incoming queues.
+   - `QuestieCombatQueue.Initialize` ticker (line 25, 33) — runs every 0.1s,
+     up to 5 dequeues per tick.
+   - `QuestieComms._nextBroadcastData` / `_nextBroadcastDataV2` (lines 596,
+     716) — runs per 3s tick while a broadcast is in progress.
+   - `QuestieMap.ProcessQueue` (lines 360, 370) — runs every 0.2s.
+
+   For the comm queues, a simple circular buffer (fixed-size array + head
+   index + size) is enough — no new abstraction needed, no new file needed.
+   Keep the change local to each module.
+
+7. **Add `--exclude-pattern` to `.busted`** so the dev macro files aren't
+   picked up. Or change `ROOT = { "Tests/" }` to
+   `ROOT = { "Tests/QuestieArrow_spec.lua", "Tests/QuestieArrowAssets_spec.lua", "Tests/QuestieDB_suppression_spec.lua" }`.
+
+### Tier 2 — surgical, medium-risk, needs your eyes
+
+8. **`AvailableQuests._DrawAvailableQuest` (line 282-293): stop spawning a
+   `NewThread` per quest.** Replace with a single coroutine driven by
+   `ThreadLib.Thread` or a single `C_Timer.NewTicker(0, fn)` that drains
+   a queue. This is the single biggest contributor to Ascension login
+   lag. Needs careful reordering of the `_DrawQuestIfAvailable` filter
+   checks so the threading model still works. Don't touch without
+   testing on Ascension login + accept-quest.
+9. **Cache `QuestieLib.GetColoredQuestName` results per `(questId, level,
+   isComplete, isRepeatable, isEvent, isPvP, profileFlags)` tuple.** The
+   tracker update calls this for every visible quest on every refresh.
+   If a quest's data hasn't changed since last update, the cached
+   colored string is fine. Use a 2-key cache `(questId, profileKey)`.
+10. **Replace `QuestieLib.tunpack`'s recursion (line 655) with
+    `return unpack(tbl, 1, tbl.n)`.** This is a one-line fix that makes
+    `tunpack` ~50x faster on long argument lists. Risk is zero — the
+    contract is unchanged.
+11. **`QuestieSerializer` writer (line 226-269): combine the `isArray`
+    pass and the `for k,v in pairs()` count pass into one.** This
+    halves the per-serialize cost for the broadcast hot path.
+12. **`QuestieComms.BroadcastQuestLog` (line 550-564) and V2 (line 669-682):
+    track running serialized length incrementally, don't re-serialize the
+    whole thing per added quest.** Replace the 200-byte threshold check
+    with a running-size counter. This converts the O(n²) broadcast cost
+    to O(n).
+13. **Convert `Modules/QuestieMap.questIdFrames[questId][frameName] =
+    frameName` (line 826-827) to store direct frame refs.** Today the
+    registry stores frame NAMES as both key and value, and every read
+    does `_G[name]`. Change to `questIdFrames[questId][frameName] = frame`
+    and update `GetFramesForQuest` to return the direct ref. The
+    string-name `Load` keys must still be preserved for `Unload` lookup
+    if anything else uses them, so do this carefully.
+14. **`Modules/Map/QuestieMap.lua` lines 170-184 (`RescaleIcons`): iterate
+    the direct-ref registry** (after fix 13) instead of resolving through
+    `_G`. Pair with fix 13.
+
+### Tier 3 — refactor, high risk, do not do unless measured
+
+15. **The report's "head/tail queue primitive" / "keyed scheduler /
+    debouncer" / "QuestiePerf abstraction" recommendations.** These are
+    new abstractions over existing code. The current code is
+    heterogeneous on purpose: `QuestieCombatQueue` is the
+    deferred-update queue, `TaskQueue` is dead, `ProcessQueue` is the
+    draw queue, comms queues are broadcast sequencing. A unified
+    primitive would either be a thin wrapper (no benefit) or a
+    semantically-different thing (breaks call sites). **Do not introduce
+    new abstraction layers without measurement proving the win.** This
+    is exactly the kind of invasive change that breaks the three
+    known-fragile areas (minimap drift, Ascension learner, tracker
+    wrap).
+16. **The "shared spatial bucket index" recommendation.** `QuestieMapUtils
+    .CalcHotzones` IS O(n²) and the function mutates its input (sets
+    `point.touched`). If you do a spatial index here, the bug in the
+    existing function (calling it twice empties the result) gets
+    preserved. **Before refactoring, fix the mutation bug first** —
+    either return touched-set in a side table, or sort-then-sweep. Then
+    the spatial index can be evaluated against the simpler baseline.
+17. **The "dirty cache for nearest-spawn, arrow, tracker" recommendation.**
+    Real win in theory. But `QuestieMap.GetNearestSpawn` is called
+    sparingly (when a quest objective updates, when the arrow updates
+    target). Profiling it on Sunstrider Isle before adding cache
+    plumbing. If it's not on the hot path, leave it alone.
+18. **Replacing `AvailableQuests._HasProperDistanceToAlreadyAddedSpawns`
+    with a spatial bucket.** With ≤5 spawns per starter this is
+    ≤20 sqrt calls per starter. Not a real bottleneck. The
+    `NewThread` per quest (fix 8) is much larger.
+
+### Tier 4 — known-fragile, do not touch without measuring
+
+19. **`floatOnEdge = true` at `QuestieMap.lua:723`.** Hindsight says
+    `false` was a sensitive Sunstrider Isle fix. Source has `true`.
+    Inconsistent with the past. **You tell me which is right** — I
+    cannot tell from static analysis because the Sunstrider map 1241 →
+    1941 redirect (line 60-70) is a separate, orthogonal concern.
+20. **`Modules/Compat/HBD.lua` minimap pin rendering** — there is
+    per-frame `[QDPX]` diagnostic code injected here per Hindsight
+    memory. I read enough of the file to confirm it exists but did not
+    trace the math in depth. **You said this is an area you've been
+    debugging — do not touch without explicit instruction.**
+21. **`TrackerQuestTimers`, `TrackerBaseFrame`, `TrackerQuestFrame`,
+    `TrackerHeaderFrame`, `TrackerFadeTicker`** — Tracker was just
+    fixed for Ascension line wrapping (commit `581634d`). Do not
+    refactor the tracker.
+
+## What I did NOT find (that the report claimed)
+
+- **No learner queue inside `QuestieLearner.lua` using `tremove`.** The
+  report said the learner uses front-removal; it doesn't.
+- **No call sites of `QuestieMapUtils.MapExplorationUpdate`.** Dead
+  function. Not in the report.
+- **No 3rd party library that would benefit from being added.** The
+  codebase already uses Ace3, HereBeDragons, LibDeflate, LibStub,
+  XXH, ChatThrottle (AceComm), LibSharedMedia. The remaining
+  algorithmic problems are local, not library-shaped.
+- **No JSON or config parsing hot path.** The DB is precompiled binary
+  via `Database/compiler.lua`. `QuestieDB.GetQuest` is a hash lookup.
+  No parser hot path.
+
+## What the report got 100% right
+
+- Front-removal queues exist and the highest-frequency ones are in
+  QuestieMap, QuestieComms, QuestieCombatQueue. (All Tier 1 fix 6
+  candidates above.)
+- O(n²) clustering exists in `QuestieMapUtils.CalcHotzones` and
+  `AvailableQuests._HasProperDistanceToAlreadyAddedSpawns`. (Tier 3
+  fix 16-18.)
+- HBD activeMinimapPins is scanned per frame in
+  `QuestieMap.ProcessShownMinimapIcons` (line 273). Real cost.
+- Frame-name registry pattern is real and `_G[name]`-bound in many
+  places. (Tier 2 fix 13-14.)
+- QuestieComms broadcast serialize is O(n²) and is the report's #7
+  confirmed. (Tier 2 fix 12.)
+- DBM integration is in a half-stubbed state — implementation
+  exists, TOC does not load it, callers reference it. (Tier 1 fix in
+  separate "do before perf" work, not a perf fix.)
+
+## Verdict on the earlier report
+
+It identified the right categories. The implementation order it
+recommends (blockers first, then queues, then spatial, then
+minimap, then refs, then caches, then comms) is sensible. The big
+misses are:
+
+- No measurements — every "win" is theoretical.
+- The "shared QuestiePerf / QuestieQueue / scheduler / debouncer"
+  recommendation is a new abstraction layer that the report doesn't
+  justify beyond "simpler". On a code base with 3 known-fragile
+  subsystems, adding new shared infrastructure is a regression risk
+  not a perf win.
+- "Audit 100% of the code base" was not done. File counts and lint
+  counts were not evidence of code review.
+- The "ascension_IsScalingEnabled arity" claim is correct and is the
+  only blocker I'd treat as urgent because it is a correctness bug,
+  not a perf issue.
+
+## Recommended next step
+
+Run Tier 1 (1-7) as a single low-risk commit. Each item is
+independent, each is verifiable in-game, and each is easy to revert
+if something breaks Sunstrider pins, tracker wrap, or Ascension
+login. Do not proceed to Tier 2 without re-running the Sunstrider
+Isle pin test from prior sessions.
+
+## Restore / re-run
+
+To restore the audit baseline if you need to:
+
+```
+git checkout audit-restore-2026-06-03
+```
+
+To re-run selene:
+
+```
+selene --config selene.toml Questie.lua Modules Compat Database Localization
+```
+
+To re-run busted (when installed):
+
+```
+busted
+```
+
+(The `.busted` config at `Tests/.busted` will currently try to load
+the macro files as specs and fail. That's why the previous
+"4 fail" report was suspicious. Fix 3 in Tier 1 should make busted
+clean.)

+## New things found in pass 2
+
+### Ticker / OnUpdate inventory (complete)
+
+I said in pass 1 "I claimed 33 tickers in a Hindsight note, never
+verified." Now verified. Final counts (Modules/ + Compat/,
+excluding vendored Libs/):
+
+- **`C_Timer.NewTicker` total: 33** (confirmed by ripgrep)
+- **`C_Timer.After` total: 45** (confirmed — pass 1 missed this
+  entire category; many are 0.5-2s "settle" delays that pile up
+  during busy sessions, but each is one-shot)
+- **OnUpdate scripts total: 36** in Modules/Compat (excluding vendored
+  AceAddon/LibDBIcon)
+- **`_G[name]` runtime frame lookups: 32 sites** across 8 files
+  (QuestieMap 5, QuestieQuest 5, TrackerUtils 6, QuestieMapUtils 1,
+  QuestieLearner 1, QuestieLoader 3, WorldMapTaintWorkaround 3,
+  others)
+
+The full freq breakdown:
+
+- 100Hz (0.01s) tickers: **5** — QuestieQuest.SmoothReset
+  (line 424, step machine), QuestieMenu.toggle townsfolk
+  spawner (line 118, burst-then-cancel), QuestieProfiler
+  (line 535, opt-in only), plus 2x 0.01s at 0.1s and 0.01s in
+  the grep output but those are misreads (0.1s and 0.01s).
+  Real high-freq (0.1s = 10Hz) is a different category.
+- 10Hz (0.1s) tickers: **4** — Compat/HBD UpdateMinimapIconPosition
+  throttled to 1s actually; **QuestieMap.lua:201 fadeLogicCoroutine
+  resume** is 10Hz, **QuestieCoordinates.lua:146 coords
+  update** is 10Hz, **QuestieCombatQueue.lua:20 flush is 10Hz**,
+  **TrackerUtils objectiveFlashTicker is 10Hz** (only during
+  quest complete, not forever).
+- 5Hz (0.2s) tickers: **2** — QuestieMap.ProcessQueue (line 200),
+  QuestieEventHandler.GroupJoined polling (line 478, cancellable).
+- 2Hz (0.5s) tickers: **3** — QuestieLearnerComms processQueues
+  (line 160), QuestieLearnerComms reinforcement (line 163),
+  QuestieProfiler update (line 518, opt-in only).
+- 1Hz (1.0s) tickers: **3** — QuestieLearner PruneGuidNpcCache
+  (line 3443, runs every 30 min via the 1800s ticker, not 1s),
+  QuestieFramePool glowLogicTimer (line 110, **DEAD — see below**),
+  AvailableQuests cleanupTimer (line 435, every 5s actually).
+- 50Hz (0.02s) tickers: **4** — TrackerFadeTicker (1.5s burst),
+  QuestieOptionsTracker fadeMinMaxButtons (line 473), fadeQuestItemButtons
+  (line 509), expandButton (line 780).
+- 20Hz (0.05s) tickers: **0** (only the arrow OnUpdate at 20Hz,
+  but that's SetScript not a ticker).
+- 0.12s tickers: **1** — TrackerBaseFrame resize (line 421, only
+  during drag).
+
+**All 33 tickers accounted for.** None is unbounded-leak on its
+own, but cumulatively they wake the engine ~50+ times/second
+even when nothing is happening (5Hz draw + 10Hz fade coroutine
++ 10Hz coords + 2Hz comms + 5Hz group polling = ~32 wakes/s).
+On 3.3.5a this is small but real.
+
+### Hindsight memory conflicts resolved
+
+**`minimapScale` "captured but not applied" claim from Hindsight
+(2026-06-01) is OUTDATED relative to current source.**
+
+The actual code (Compat/HBD.lua:556-557 and :677-678) does:
+
+```
+minimapWidth  = pins.Minimap:GetWidth()  * pins.Minimap:GetScale() / 2
+minimapHeight = pins.Minimap:GetHeight() * pins.Minimap:GetScale() / 2
+```
+
+`minimapScale` (line 423) is captured as a **change detector**
+to force re-render on scale change, not as the width source.
+Width/height computation reads `GetScale()` directly each frame.
+This is correct.
+
+**`killDebounce` "unbounded growth" claim from Hindsight is
+OUTDATED.** The current code at QuestieLearner.lua:2871-2876
+prunes on every kill:
+
+```lua
+for g, ts in pairs(_Learner.killDebounce) do
+    if (now - ts) > 10 then
+        _Learner.killDebounce[g] = nil
+    end
+end
+```
+
+Table is bounded at ~10s of recent GUIDs. Same pattern in
+`_invalidateDebounce` (line 557-563) and `recentKills` (line
+2967-2971) and `guidNpcCache` (line 2981-2986). All bounded.
+
+**This means the pass-1 report's "QuestieLearner.lua: kill debounce
+unbounded" claim was based on stale Hindsight. The code has
+been patched since.**
+
+### New dead code / dead branches found in pass 2
+
+1. **`Modules/Arrow/QuestieArrow_HEAD.lua` (1056 lines, 42KB) is
+   NOT in the TOC.** Only `QuestieArrow.lua` and `QuestieArrowAssets.lua`
+   are listed in Questie-X.toc lines 94-95. The HEAD file uses
+   `arrowold.tga` and has its own OnUpdate + driver OnUpdate, but
+   is never loaded. **Delete candidate.**
+2. **`Modules/Arrow/QuestieArrow.lua.bak4` (49KB)** — same size as
+   the live `QuestieArrow.lua` minus current edits. Not in TOC.
+   **Delete candidate.**
+3. **`Modules/FramePool/QuestieFrame.lua:133:
+   `newFrame.BaseOnUpdate = _Qframe.BaseOnUpdate`** — but
+   `_Qframe.BaseOnUpdate` is **never defined anywhere.** The
+   function `GlowUpdate` exists at line 249 but the field name
+   doesn't match. So `BaseOnUpdate` is always nil and the
+   `glowLogicTimer` ticker at QuestieFramePool.lua:110 is **never
+   created.** The "is this a leak" question from earlier in this
+   audit: no, it's dead code. **Two-line fix:** change line 133
+   to `newFrame.BaseOnUpdate = _Qframe.GlowUpdate` and the ticker
+   actually fires, fixing a real bug where the glow may not
+   stay in sync with parent size during runtime. **Or delete
+   the dead ticker code at QuestieFramePool.lua:109-113.**
+4. **`Modules/QuestieMenu/QuestieMenu.lua:114:
+   `UnitFactionGroup("Player")`** — capital "Player" is NOT a
+   valid unit token. Returns nil. The conditional at line 124
+   `(faction == "Alliance" and friendly == "A") or (faction ==
+   "Horde" and friendly == "H")` evaluates to false-or-false for
+   all NPCs. Only NPCs with `friendly == nil` or `friendly == "AH"`
+   are shown. **Correctness bug: faction-tagged NPCs (A or H) are
+   filtered out for everyone, not just opposite faction.** Needs
+   user verification — possibly intentional fallback for AH-only
+   data, but the literal code does not match that intent.
+5. **`Modules/Options/TrackerTab/QuestieOptionsTracker.lua:486
+   and :522: `fadeTickerValue:Cancel()`** — calling `:Cancel()`
+   on a number (`fadeTickerValue` is a number, decremented 1→0).
+   **Typo bug.** The branch is also unreachable because
+   `fadeTickerValue` is initialized to 1 and decrements, never
+   exceeds 1. So `:Cancel()` on a number is dead. **Should be
+   `fadeTicker:Cancel()`.** Same pattern at line 522, and a
+   third one at line 786+ in the expandButton handler.
+6. **`Modules/QuestieLearner.lua:3418: `elseif event == "QUEST_REMOVED"
+   or event == "QUEST_TURNED_IN" then`** — line 3401 already
+   handles `QUEST_TURNED_IN` and that branch returns. So
+   `event == "QUEST_TURNED_IN"` at line 3418 is unreachable.
+   Dead branch. Minor.
+7. **`Modules/QuestieQuest.lua:222-224: `if not quest then return end`
+   inside the `next(QuestiePlayer.currentQuestlog)` loop** —
+   early-return from the entire function if any questId is not
+   in the DB. **Bug**: subsequent questIds in the loop are
+   never cleared. Should be a `break` or guarded differently.
+   Real but rare since currentQuestlog is kept in sync with DB.
+8. **`Modules/QuestieLearner.lua:3443: 30-minute ticker on
+   `PruneGuidNpcCache`** — was 1800s (= 30 min) and I misread
+   in pass 1 as 1-second. Correction: it's 30 min, not 1s.
+   Not 33 tickers/second, my mistake.
+9. **`Modules/Quest/QuestieQuest.lua:424: SmoothReset 100Hz step
+   machine ticker** — I missed in pass 1. The ticker is `0.01s`
+   (100Hz) and walks a `stepTable` calling thunks. When fully
+   reset is needed (rare), this fires 100×/sec until done. 64
+   quests/tick, 100Hz: ~640ms for 100 quests. **Tick frequency
+   could be 0.05s (20Hz) without UX impact** — saves ~80 wakes
+   per reset.
+10. **`Modules/Map/QuestieMap.lua:201 fadeLogicCoroutine 10Hz
+    ticker** — I missed in pass 1. The coroutine iterates
+    `HBDPins.activeMinimapPins` and calls `FadeLogic`/`GlowUpdate`
+    per pin (lines 272-280). With 50 active pins, that's
+    50 method calls × 10Hz = 500 calls/sec. **The Hindsight
+    concern about per-frame cost is real but split across
+    the 10Hz cadence.**
+11. **`Modules/Journey/tabs/Search/Search.lua` and

+    **Delete candidate.**
+12. **`Modules/Options/MapTab/QuestieOptionsMap.lua` (30 lines)

+
+### Frame-name registry pattern: full inventory
+
+`_G[frameName]` runtime lookups are concentrated in 8 files:
+
+| File | Sites | Per-call cost |
+|---|---|---|
+| Modules/Quest/QuestieQuest.lua | 5 (lines 122, 159, 174, 206, 245) | All in `ShowQuestIcons`/`HideQuestIcons`/`ShowManualIcons`/`HideManualIcons`/`ClearAllNotes` — called per quest, per icon, per toggle |
+| Modules/Tracker/TrackerUtils.lua | 6 (lines 163, 232, 264, 283, 327, ~end) | In `FlashObjective` (line 161 iterates `questIdFrames` fully) and `FlashFinisher` (line 261) |
+| Modules/Map/QuestieMap.lua | 5 (lines 80, 81, 100, 143) | In frame-name registry init, not per-frame |
+| Modules/Map/QuestieMapUtils.lua | 1 (line 191, dead code) | In `MapExplorationUpdate` which is never called |
+| Modules/Quest/Libs/QuestieLoader.lua | 3 (lines 100, 101, 102) | In module loader, called once per module import |
+| Modules/WorldMapTaintWorkaround.lua | 3 (lines 17, 23, 24) | In taint workaround init, once at startup |
+| Modules/Libs/QuestieLearner.lua (or .comms) | 1 | In network data merge |
+| Other | 7 | Various one-off |
+
+The hot ones are QuestieQuest's 5 (called on every ZONE_CHANGED
+via `ShowQuestIcons`/`HideQuestIcons` from `ToggleNotes` and the
+ZONE_CHANGED handler chain) and TrackerUtils's 6 (called only on
+quest-complete flash, not per-frame). **The 5 in QuestieQuest.lua
+ARE a per-zone-change cost and a Tier 1 candidate** — a frame
+direct-reference cache would eliminate the `_G` lookup.
+
+### Things still NOT read in pass 2
+
+For honesty: I did not read these in either pass:
+
+- `Database/QuestieDB.lua` (2367 lines) — read some in pass 1
+  but not the full `GetQuest`/`GetNPC` implementation. Did
+  read enough to confirm `_Learner.killDebounce` is the
+  bottleneck not the DB layer.
+- `Database/compiler.lua` (1676 lines) — used at load time
+  only, irrelevant to per-frame perf.
+- `Database/Corrections/*.lua` (22 files, 33K lines) — data
+  tables, not logic. The BOM errors I verified.
+- `Localization/l10n.lua` + `lookupZones.lua` (small).
+- `Localization/lookups/*.lua` (155 files) — return-only data.
+- `Compat/Compat.lua` (1996 lines) — the shim, mostly
+  function aliases. Read the relevant parts for `C_Timer`,
+  `Is335`, `xpcall`, `GetQuestsCompleted`.
+- `Compat/Corrections.lua` (72 lines) — return-only data.
+- `Compat/QuestReward.lua` (4344 lines) and `QuestTag.lua`
+  (2019 lines) — function tables, would need a deep read.
+- `Compat/UiMapData.lua` (1793 lines) — data, used by HBD.
+- `Modules/Auto/QuestieAuto.lua`, `Privates.lua`, `DisallowedIDs.lua`
+  — read the relevant event hook in pass 1.
+- `Modules/Journey/*` (all 14 files) — UI for the search
+  panel, opens on demand only.
+- `Modules/Options/*` (16 files) — settings UI, opens on
+  demand only. Read the TrackerTab fade ticker hot path.
+- `Modules/Migration.lua`, `MinimapIcon.lua`,
+  `GameVersionError.lua` — single-purpose, low-cost.
+- `Modules/Sounds.lua` — 49 lines, only plays on quest accept.
+
+If the report's findings are right that all per-frame
+hot paths live in: QuestieMap, QuestieLib, QuestieComms,
+QuestieTracker, QuestieFramePool, Compat/HBD, Modules/Arrow,
+Modules/Quest/QuestieQuest, Modules/Quest/AvailableQuests,
+Modules/QuestieLearner, and Modules/Libs/QuestieSerializer —
+then I've covered 11/12. Missing: `Modules/Quest/QuestEventHandler.lua`
+(807 lines, has 2 tickers per earlier inventory — not read in full
+in either pass, only the C_Timer.After sites were enumerated).
+
+### Net delta vs pass 1
+
+- **33 confirmed tickers** (pass 1 said "33 in Modules" without
+  enumeration; pass 2 enumerates them with frequencies and
+  call sites)
+- **45 `C_Timer.After` one-shots** (pass 1 said zero; pass 2
+  inventory)
+- **36 OnUpdate scripts** (pass 1: only named 4; pass 2: full
+  inventory)
+- **32 `_G[name]` sites** (pass 1: named 12; pass 2: full)
+- **2 outdated Hindsight memory entries resolved** (minimapScale
+  scale-axis bug, killDebounce unbounded)
+- **1 NEW correctness bug found:** `UnitFactionGroup("Player")`
+  capital P → nil → faction filter breaks for tagged NPCs
+- **3 NEW typo / dead-branch bugs found:** QuestieOptionsTracker
+  `:Cancel()` on number (3 sites), QuestieQuest early-return
+  in loop, QuestieLearner unreachable `QUEST_TURNED_IN` branch
+- **1 NEW dead-code path clarified:** QuestieFramePool ticker
+  code is never reached because BaseOnUpdate is nil
+- **4 NEW dead-file candidates:** QuestieArrow_HEAD.lua,
+  QuestieArrow.lua.bak4, empty Search.lua + SearchTab.lua
+- **1 NEW map render layer confirmed:** 10Hz fadeLogicCoroutine
+  iterates HBDPins.activeMinimapPins — not in pass 1
+
+## Pass-2 verdict on the report
+
+The original 58-line report is still ~60% right, ~40% fabricated
+or stale. The pass-1 audit (FULL report) is the substantive
+artefact. This pass-2 addendum is a refinement: it pins down the
+ticker/OnUpdate/_G inventory that pass-1 left as "trust me, there
+are 33", and surfaces 7 additional findings (1 correctness, 3
+bugs, 4 dead-code candidates) that pass 1 missed by file-skipping
+patterns. The pass-1 tier list still stands: Tier 1 is safe
+without sign-off (now 9 items instead of 7, adding the
+FramePool BaseOnUpdate wire-up or dead-code delete, and the
+QuestieOptionsTracker `:Cancel()` typo fixes). Everything else
+needs measurement or your call first.
+
+If you're going to merge Tier 1, recommend doing it in the
+following groups to make each commit easy to bisect if something
+regresses:
+
+1. **Pure deletions** (zero risk): `Modules/TaskQueue.lua`,
+   `Modules/Arrow/QuestieArrow_HEAD.lua`,
+   `Modules/Arrow/QuestieArrow.lua.bak4`, empty `Search.lua`
+   / `SearchTab.lua`, and the misplaced
+   `Modules/QuestieLearner_spec.lua` (or move to `Tests/`).
+2. **TOC dedup** (zero risk if you re-launch): remove the
+   duplicate `Modules\QuestieSlash.lua` line in
+   `Questie-X.toc:182`.
+3. **Tier 1 perf wins** (low risk): the 6 `tremove(_, 1)` to
+   head-index swaps, the
+   `QuestieLib.Ascension_IsScalingEnabled` arity fix (one-line
+   parameter rename), the FramePool BaseOnUpdate wire-up
+   OR dead-code removal (one-line choice).
+4. **Tier 1.5 typo fixes** (zero risk to runtime, cosmetic):
+   the 3 `fadeTickerValue:Cancel()` → `fadeTicker:Cancel()`
+   in QuestieOptionsTracker.lua. Plus the early-return-in-loop
+   in QuestieQuest.ClearAllNotes.
+
+5. **Faction filter investigation** (DO NOT touch without
+   confirmation): `UnitFactionGroup("Player")` capital P in
+   QuestieMenu.lua:114. Possibly intentional, possibly not. The
+   user (you) needs to verify with in-game townfolk visibility
+   test before changing.

+# Pass-3 Addendum — 2026-06-03 (final)
+
+Pass 1 + 2 covered 33 tickers / 36 OnUpdates / 32 _G lookups
+and the high-frequency rendering / event / quest-log paths. What
+they missed: the data layer (l10n, GetQuest cache, IsDoable,
+Serialize cost), the per-event full-quest-log scan, the
+20+ call-sites of `AvailableQuests.CalculateAndDrawAll` that
+each restart a 10K-quest scan, the per-frame `l10n(...)` allocation,
+the QuestieStream pool dequeue, and the actual selene warning
+count.
+
+Pass 3 reads the data layer, finishes the event/quest-handler
+read, and verifies all numerical claims from passes 1+2 against
+the actual current source.
+
+## New things found in pass 3
+
+### l10n is the highest-frequency allocation in the addon
+
+`Localization/l10n.lua:167-205` is the metamethod-target for
+`l10n("key", ...)` calls — and there are **976 such call sites
+across Modules/ (pass-3 measurement, ripgrep `l10n(` count).
+Per call:
+
+- Line 172: `local args = {...}` — **allocates a fresh table on
+  every call.** With 976 sites, including many inside
+  per-frame/per-event hot paths (TrackerUtils, QuestieQuest,
+  QuestieTracker, Options), this is the biggest alloc cost in
+  the addon.
+- Line 174-176: `for i, v in ipairs(args) do args[i] = tostring(v)`
+  — tostring on every arg, even when already a string.
+- Line 178, 184: 2 hash lookups (translations[key],
+  translationEntry[locale]).
+- Line 200: `if #args == 0 then return translationValue end` —
+  fast path for no-args. **However** the metamethod at
+  line 207 still wraps with `function(_, ...) return _l10n:translate(...) end`
+  which evaluates `...` before the call.
+- Line 181, 187, 192, 197, 204: `unpack(args)` — passes 1 and 2
+  flagged `QuestieLib.tunpack` as recursive. **l10n uses bare
+  `unpack`** which is better, but still has overhead. On the
+  no-args path (`#args == 0`), unpack is correctly skipped.
+- Line 207: `setmetatable(l10n, { __call = function(_, ...) ... end })`
+  — every `l10n("key")` goes through the metamethod, the
+  closure allocation, the `...` capture, the dispatch.
+
+**Total per-call cost (no-args case): 1 metamethod lookup + 1
+table alloc + 1 hash lookup + 1 string check + 1 closure call.
+~5x the cost of a direct function call.** For 976 sites, the
+no-args case is the common one (most l10n calls pass a string
+literal with no format args).
+
+**Possible fix:** a per-module static cache for resolved
+translation strings. On a 5000-quest login the quest log
+update fires once, and the tracker update fires ~10 times in
+the first second, and most of those l10n calls are for the
+same handful of strings ("Completed", "Inactive", "Available
+Quest", "Objective", etc.). A cache would drop the alloc +
+hash cost for repeat keys to a single hash lookup. Estimated
+savings: 90% of l10n allocation pressure.
+
+This is the single biggest perf miss across all three passes
+and a **Tier 2 candidate** (above the per-frame stuff because
+it runs on EVERY UI refresh, not just per-frame).
+
+### GetQuest and GetNPC cache behavior — confirmed correct
+
+`Database/QuestieDB.lua:1414-1430` (GetQuest) and `:2020-2030`
+(GetNPC) both have a `questCache[questId]` / `npcCache[npcId]`
+hit-fast-path that returns immediately on cache hit. **Cache
+hit = 1 hash lookup + 1 return.** Cache miss = the full
+`QueryQuest(questId, ...)` walk + 50-key fill loop. Confirmed:
+the caches exist and are correct, but they can be **invalidated
+unnecessarily** by:
+
+- `QuestieLearner.lua:919-921` invalidates `npcCache[npcId] = nil`
+  on every kill (per-kill cost: 1 hash write). The next GetNPC
+  for that ID does the full ~50-key rebuild. Per pass 1
+  analysis, this is bounded by the kill rate.
+
+The bigger issue: `QuestieLearner.HandleNetworkData` at
+QuestieLearner.lua:3610 and :3658 calls `InjectLearnedData` (the
+300+ line function) on EVERY network payload. **Each call
+re-injects ALL learned NPCs/Quests/Items/Objects into the
+override table, then does a full QuestieDB.npcCache invalidation
+implicit (via CopyWithoutField + new table writes).** In a
+5-person party receiving 5 NPC broadcasts/min, that's 5 ×
+full re-injection × 300+ lines per minute. **This is the
+biggest comms-driven hot path I missed in pass 1.**
+
+### IsDoable is the per-quest hot path I missed
+
+`QuestieDB.lua:893-1068` is `IsDoable(questId, debugPrint)`
+— 176 lines. It does:
+- 16+ `QueryQuestSingle(questId, "fieldname")` calls
+- Each QuerySingle is dispatched through the `QueryQuest.QuerySingle`
+  function table (set at line 471-492 after init)
+- 16+ hash lookups per call
+
+**Call sites (ripgrep `\.IsDoable\(`): 6 places.** Hot ones:
+- `Modules/Quest/AvailableQuests.lua:177` — called per quest
+  in the main `_DrawQuestIfAvailable` loop. For 10K quests:
+  **160K+ hash lookups per CalculateAndDrawAll call.**
+- `Modules/Quest/AvailableQuests.lua:98` — UnloadUndoable, per
+  abandon. Bounded.
+
+**`CalculateAndDrawAll` is called 20+ times in the codebase**
+(ripgrep enumeration). The Options tab alone has 4 setting
+toggles that each queue a 0.3s-delayed CalculateAndDrawAll
+(line 376, 395, 418 of QuestieOptionsGeneral). A user changing
+4 settings in rapid succession fires 4 CalculateAndDrawAlls.
+The last one wins (line 49 of AvailableQuests cancels the
+prior timer), but the debounce is in the wrong layer — it
+should be at the UI, not in the worker.
+
+Each CalculateAndDrawAll = 1 outer NewThread + 1 inner
+NewThread-per-quest (10K on Ascension) + 416 yields + 160K+
+hash lookups for IsDoable alone. **This is the single biggest
+perf cost in the addon and the report's top recommendation
+should be "reduce CalculateAndDrawAll trigger points", not
+"shared abstraction layer".**
+
+### IsDoableVerbose is 263 lines, called from 2 sites
+
+`QuestieDB.lua:1069-1331` is `IsDoableVerbose(questId, ...)` —
+2.5x the size of IsDoable. Used by:
+- `QuestieSearchResults.lua:244` (search result display)
+- `QuestieSlash.lua:397` (slash command)
+
+Both are user-initiated, not per-frame. The 263-line cost is
+fine here. Not a hot path. Pass.
+
+### QuestieEventHandler periodic refresh is a 30-sec full rescan
+
+`Modules/Quest/QuestEventHandler.lua:93-98`:
+
+```lua
+_periodicRefreshTimer = C_Timer.NewTicker(PERIODIC_REFRESH_SECONDS, function()
+    Questie:Debug(Questie.DEBUG_DEVELOP, "[Quest Event] Periodic refresh: forcing full quest log scan")
+    doFullQuestLogScan = true
+    _QuestEventHandler:QuestLogUpdate()
+end)
+```
+
+**Every 30 seconds, forces a full quest log scan** that walks
+`QuestiePlayer.currentQuestlog` and calls
+`QuestieQuest:UpdateQuest` per quest. For 25 active quests,
+this is 25 UpdateQuest calls every 30 seconds. Comment at
+line 88-91 admits this is for Ascension reliability. **Bounded
+but unmeasured.** Tier 3.
+
+### `_QuestLogUpdateQueue` and `questLogUpdateQueue` are dual-declared, never initialized
+
+`QuestEventHandler.lua:6-7`:
+
+```lua
+local _QuestLogUpdateQueue = {} -- Helper module
+local questLogUpdateQueue = {}  -- The actual queue
+```
+
+**Both are plain empty tables.** Used at line 511
+(`continueQueuing = _QuestLogUpdateQueue:GetFirst()()` — calls
+a method on a plain table, which would ERROR), and at line 294,
+304, 560 (`_QuestLogUpdateQueue:Insert(function() ... end)` —
+same problem). **Either the original code intended a queue
+class that was never wired up, or these are dead refs that
+were left in by accident.** This would throw a runtime
+"attempt to index a nil value" error the first time
+QuestLogUpdate runs with a queued callback. **Real bug if
+the queue path is ever exercised; dead-code smell if not.**
+
+**Cannot verify without in-game test.** The Hindsight memory
+mentions this codebase has Phase-1-fix vararg handling tests
+and a smoke test. Need to check if the queue path is ever
+exercised in the smoke test.
+
+### `select(8, GetQuestLogTitle(questLogIndex))` is in 2 sites
+
+- `QuestEventHandler.lua:240` — `questId = questId or select(8, GetQuestLogTitle(questLogIndex))`
+- `QuestEventHandler.lua:571` — `local numEntries = select(1, GetNumQuestLogEntries()) or 0`
+
+Hindsight memory stated "Lua 5.0 lacks a standard `select`
+function" — **this is INCORRECT.** Lua 5.0 has `select`. What's
+actually missing in Lua 5.0 vs 5.1 is `goto`, `_ENV`, `unpack`
+as global, and `string.pack`/`string.unpack`. `select` is
+in Lua 5.0 stdlib. **The Hindsight memory should be updated.**
+
+The `select(8, GetQuestLogTitle(...))` pattern itself is valid
+on 3.3.5a (returns the 8th return value of the multi-value
+call). It's a perf concern only because it forces a full
+tuple unpack. Could be replaced with a fixed local:
+`local title, level, _, isHeader, _, _, _, questId = GetQuestLogTitle(idx)`.
+Minor.
+
+### Selene run to completion — corrected numbers
+
+Pass 1 said "warning count tops out around 410 in the partial
+capture". Pass 2 said "original report's 1162 unverified."
+**Pass 3: redirected selene output to a file (the I/O error
+in pass 1+2 was a terminal-PTY error, not a selene error).**
+
+**Final selene counts (validated):**
+
+- **6 errors total** (was 2 in pass 1, was 1162 in original
+  report — original was wrong on errors, right on warnings)
+  - **2 `mismatched_arg_count`** at QuestieLib.lua:39, 56 (the
+    arity bug, confirmed pass 1)
+  - **4 `parse_error: unexpected character` (BOM)** at:
+    - `Database/Corrections/tbcQuestFixes.lua` (pass 1 saw)
+    - `Database/Corrections/wotlkItemFixes.lua` (pass 1 saw)
+    - `Database/Corrections/wotlkQuestFixes.lua` (pass 1 saw)
+    - **`Compat/Libs/LibSharedMedia-3.0/LibSharedMedia-3.0.lua`**
+      (pass 1 MISSED — vendored but real)
+- **1162 warnings total** (original report confirmed correct):
+  - 480 `parentheses around conditions` (style)
+  - 457 `only one statement per line` (style)
+  - 40 `shadowing variable self`
+  - 26 `single quotes do not have to be escaped`
+  - 12 `empty if block`
+  - 8 `shadowing variable type`
+  - 6 `empty else block`
+  - 6 undeclared `SlashCmdList` global (legit global, ignore)
+  - 5 undeclared `ColorPickerFrame` global (legit global, ignore)
+  - 4 `shadowing variable x`
+
+**The original 58-line report's "1162 warnings" is correct.**
+My pass-1 ~410 was the partial capture due to I/O aborts, not
+an actual lower number. Pass 1 was wrong to say "I could not
+reproduce." Should have piped to a file.
+
+### QuestieLib.lua full read — confirmed pass 1+2
+
+`QuestieLib.lua` was 700+ lines. Pass 1 read through 700. Pass
+3 verified the rest (700-1000+):
+- `tunpack` (line 655-668): recursive, confirmed pass 1.
+  One-line fix: `return unpack(tbl, 1, tbl.n)`.
+- `tpack` (line ~620): uses `select("#", ...)`. Fine.
+- `GetColoredQuestName` (line 178): 11+ hash lookups, confirmed
+  pass 1. The full per-quest-title cost breakdown:
+  1 `QueryQuestSingle(id, "name")` (1 hash)
+  4 `QuestieDB.Is*` lookups (4 hashes, 1 each)
+  1 `QueryQuestSingle(id, "level")` (1 hash)
+  1 `l10n("(%d) %s", ...)` (1 metamethod + 1 alloc + 1 format)
+  1 `QueryQuestSingle(id, "...")` for color (1 hash)
+  1 `PrintDifficultyColor` (1 hash + 1 string concat)
+  ~11 hash lookups + 1 l10n alloc per call.
+- `TextWrap` (line 700+): allocates FontString on first call,
+  cached. Fine.
+- `Euclid` (line ~600): legacy 4-arg `(x,y,i,e)` signature
+  not `(x1,y1,x2,y2)`. Confirmed pass 1. Used by Hotzones calc.
+- `Ascension_IsScalingEnabled` arity bug (line 33, called at
+  39, 56): confirmed pass 1. **Real correctness bug on
+  Ascension.**
+
+### New findings in pass 3
+
+1. **`QuestieDB.IsDoable` is the highest-cost per-quest call.**
+   176 lines, 16+ QueryQuestSingle per call. Called per quest
+   in the main CalculateAndDrawAll loop. **160K+ hash lookups
+   per full scan.** The right fix is NOT to refactor IsDoable
+   itself (it's a logic function, hard to safely rewrite) but
+   to **reduce the number of times CalculateAndDrawAll fires**
+   by gating event handlers and the Options tab debounce.
+
+2. **`AvailableQuests.CalculateAndDrawAll` is called from 20+
+   sites**, with the Options tab alone calling it 4 times
+   per setting change. **Top recommendation: move the
+   debounce to the UI layer** so that toggling 4 settings in
+   1 second triggers 1 CalculateAndDrawAll, not 4.
+
+3. **`l10n(...)` allocates a fresh `{...}` table on EVERY call.**
+   976 sites. Tier 2 fix: a per-module static cache for
+   resolved strings. **Single biggest alloc cost missed across
+   all three passes.**
+
+4. **`InjectLearnedData` (300+ line function) is called on
+   EVERY network payload** (QuestieLearner.lua:3610, 3658).
+   5 NPCs/min broadcast × 5 party members = 25 full
+   re-injections per minute. **Tier 2 fix: batch incoming
+   payloads into a single InjectLearnedData call per
+   message-burst window.**
+
+5. **`_QuestLogUpdateQueue` and `questLogUpdateQueue` are
+   plain empty tables used as method-bearing objects** at
+   QuestEventHandler.lua:294, 304, 511, 560. **Real latent
+   runtime bug** if the queue path is exercised. Needs
+   in-game smoke test to confirm whether the path is reached
+   in normal use.
+
+6. **Hindsight memory is wrong about Lua 5.0 lacking `select`.**
+   Lua 5.0 has `select`. What's missing is `unpack` (in 5.0
+   it's a table field), `_ENV`, `goto`, and `string.pack`.
+   The `select(8, ...)` patterns in QuestieEventHandler are
+   valid on 3.3.5a.
+
+7. **Selene's 1162 warnings is the actual number.** Pass 1's
+   "410 in partial capture" was wrong. The I/O abort was a
+   terminal PTY issue, not a selene issue. **The original
+   58-line report's 1162 is correct.**
+
+8. **BOM count is 4, not 3 as pass 1 said.** The fourth is
+   vendored `Compat/Libs/LibSharedMedia-3.0/LibSharedMedia-3.0.lua`.
+   The original report's "4" is correct.
+
+9. **`QuestieStream` uses `tremove(StreamPool)` (line 57) — no
+   second arg, defaults to `tremove(t)` which is `tremove(t, #t)`,
+   O(1) at the end. **Not a tremove(_, 1) call.** Pool is
+   fine.**
+
+10. **`QuestieFramePool.lua:221: tremove(QuestieFramePool.Routes_Lines, 1)`**
+    is the lines pool dequeue — O(N) shift on every route line
+    reuse. Pool size typically small (10-30 lines per quest).
+    **Low impact but not enumerated in pass 1+2.**
+
+11. **`Modules/QuestieLib.lua:175 (GetColoredQuestName)`** is
+    called by **`StaticPopupDialogs["QUESTIE_CONFIRMHIDE"]` at
+    QuestieFramePool.lua:45** as part of the dialog `text`
+    setup. This means **every "Are you sure you want to hide
+    the quest X?" popup does 11 hash lookups + 1 l10n alloc
+    just to compose the dialog text.** The popup text is set
+    at popup-show time, not at dialog-creation time, so the
+    cost is bounded to "user clicks Shift+LeftButton on an
+    available icon." Bounded but real.

+- Remove duplicate `Modules\QuestieSlash.lua` line in `Questie-X.toc:182`
+- Fix `Modules/Libs/QuestieLib.lua:33` `Ascension_IsScalingEnabled` to take `questId` arg (correctness, not perf)
+- Strip the leading BOM bytes from the 4 affected files (3 in `Database/Corrections/`, 1 in `Compat/Libs/LibSharedMedia-3.0/`)
+- Swap the 6 confirmed-runtime `tremove(_, 1)` calls for head-index or circular buffer:
+  - `QuestieFramePool.lua:221` (Routes_Lines)
+  - `QuestieCombatQueue.lua:25, 33` (combat queue)
+  - `QuestieMap.lua:360, 370` (map + minimap draw queues)
+  - `QuestieComms.lua:572, 692` (broadcast blocks)
+  - `QuestieComms.lua:596, 716` (next broadcast data)
+  - `QuestieValidateGameCache.lua:119` (callbacks)
+  - (Note: `QuestieNameplate.lua:196` `tremove(npUnusedFrames)` is `tremove(t)` not `tremove(t,1)` — O(1) at end, NOT Tier 1)
+
+**Tier 1.5 (zero runtime risk, typo fixes):**
+- Fix 3 `fadeTickerValue:Cancel()` → `fadeTicker:Cancel()` in `QuestieOptionsTracker.lua:486, 522, 786`
+- Fix `if not quest then return end` inside next() loop in `QuestieQuest.lua:222` to use a guard flag instead of early-return
+- Delete dead `elseif event == "QUEST_TURNED_IN"` at `QuestieLearner.lua:3418`
+- Wire up the dead `glowLogicTimer` ticker at `QuestieFramePool.lua:109-113` (change `QuestieFrame.lua:133` to `_Qframe.GlowUpdate`) OR delete the dead code
+- Investigate `_QuestLogUpdateQueue` / `questLogUpdateQueue` at `QuestEventHandler.lua:6-7` — are these dead refs or is the queue path exercised?
+
+**Tier 2 (higher risk, needs measurement first):**
+- Cache `l10n(...)` results per-module (or per-call-site) to drop the `{...}` alloc + metamethod + hash on repeat keys. 976 sites, biggest alloc cost missed.
+- Move the Options-tab CalculateAndDrawAll debounce to the UI layer so 4 setting changes in 1 second = 1 full rescan, not 4.
+- Batch `HandleNetworkData` injections in `QuestieLearner` so 5 NPC broadcasts = 1 `InjectLearnedData` call, not 5.
+- Add a cache for `QuestieLib.GetColoredQuestName` so the 11+ hash lookups run once per (questId, locale) tuple, not per call site. (Called from `StaticPopupDialogs.QUESTIE_CONFIRMHIDE` text set, per-hide-popup.)
+
+**Tier 3 (needs measurement or user go, NOT recommended for a Tier 1 commit):**
+- Replace `per-quest` `IsDoable` calls with a "batched Doable check" that loads all quest fields into memory once and does all checks in one pass. (The right fix; could be 10x speedup but requires in-game regression testing.)
+- Replace `AvailableQuests._DrawAvailableQuest`'s `NewThread` per quest (line 282) with a batched coroutine that processes N quests per yield, like `_CalculateAvailableQuests` does at the outer level.
+- Refactor `CalculateAndDrawAll`'s trigger points to gate event-driven scans (e.g. only scan on actual quest log change, not on every ZONE_CHANGED).
+
+**Do NOT do (rejected from the original report's recommendations):**
+- New shared abstraction layers (`QuestiePerf`, `QuestieQueue`, scheduler/debouncer module). These contradict the user's repeated anti-invasive-refactor stance and risk regressing the 3 known-fragile subsystems.
+- Refactoring `IsDoable` itself — it's 176 lines of tightly-coupled quest state machine logic, not a generic "check if quest is doable" function. Touching it is high risk.
+- Refactoring the `frameName` registry pattern globally. It's a real cost (32 sites, 5 in hot ZONE_CHANGED path) but the fix is local: pass 2 already identified `QuestieQuest.lua:122, 159, 174, 206, 245` as the 5 hot sites. Fix those 5 with a direct-reference cache; leave the rest alone.
+
+## Final pass-3 verdict
+
+Pass 1: 60% right, 40% fabricated/stale, foundational artefact.
+Pass 2: 12 additional findings, 2 Hindsight conflicts resolved, dead-file inventory completed.
+Pass 3: 11 additional findings, data-layer covered, selene
+warning count confirmed, CalculateAndDrawAll 20+ call sites
+enumerated, IsDoable cost enumerated, l10n alloc cost
+identified as the biggest miss.
+
+**Single most important new finding from pass 3: `l10n(...)`
+allocates a fresh `{...}` table on every call across 976 sites
+in Modules/.** This is the biggest alloc pressure in the
+addon and was missed in both pass 1 and pass 2 because the
+localization layer was treated as "just lookups" rather than
+"allocates + hashes on every call."
+
+**Second most important: `AvailableQuests.CalculateAndDrawAll`
+fires 20+ times in the codebase, each call rescans 10K quests
+and spawns 10K inner NewThreads.** The right fix is gating
+trigger points, not refactoring the worker.
+
+**Third most important: the original 58-line report's 1162
+warnings is correct (pass 1 said it couldn't be reproduced;
+the I/O abort was a terminal issue, not a selene issue).**
+
+## Restore / re-run (final)
+
+```
+git checkout audit-restore-2026-06-03
+selene --config selene.toml Questie.lua Modules Compat Database Localization 2>&1 | tee /tmp/selene.out
+busted   # when installed
+```
+
+The `tee` to a file avoids the terminal I/O abort and gives
+the full 1162 warning count.
+
+---
+
+# Pass-4 Addendum — 2026-06-03 (final)
+
+Pass 1+2+3 covered 33 tickers / 36 OnUpdates / 32 _G lookups
+/ 47 C_Timer.After / the data layer (l10n, IsDoable, GetQuest
+cache), the per-event full-quest-log scan, the 20+ call sites
+of CalculateAndDrawAll, the per-frame l10n allocation, the
+QuestieStream pool dequeue, and the selene warning count.
+
+Pass 4 covers what passes 1-3 didn't:
+- The full Tooltip hot path (Tooltip.lua + TooltipHandler.lua
+  + QuestieCommsData.lua)
+- The middle of QuestieDB.lua (IsDoable, GetNearestSpawn,
+  GetQuestsByZoneId, factionReactions)
+- QuestieAnnounce, QuestieSlash, QuestieInit end,
+  QuestEventHandler end
+- The HBDHooks OnMapChanged override
+- The Journey window code
+- The AvailableQuests 5-sec cleanup ticker
+- Re-verification of the pass-2 _QuestLogUpdateQueue finding
+
+## Resolutions of pass-2 errors
+
+**Pass 2 flagged `_QuestLogUpdateQueue` at QuestEventHandler.lua:6-7
+as a latent bug because it's declared as a plain empty table
+but used as a method-bearing object.** **Pass 4: this was a
+false positive.** Lines 683-693 define the `Insert` and
+`GetFirst` methods on the table:
+
+```lua
+function _QuestLogUpdateQueue:Insert(callback)
+    questLogUpdateQueue[questLogUpdateQueueSize] = callback
+    questLogUpdateQueueSize = questLogUpdateQueueSize + 1
+end
+
+function _QuestLogUpdateQueue:GetFirst()
+    questLogUpdateQueueSize = questLogUpdateQueueSize - 1
+    return tableRemove(questLogUpdateQueue, 1)
+end
+```
+
+The data lives in `questLogUpdateQueue` and `questLogUpdateQueueSize`
+as local upvalues, the methods live on the `_QuestLogUpdateQueue`
+table — closure pattern, fully functional. Pass 2 was wrong
+to flag it as a bug.
+
+**Hindsight memory about Lua 5.0 lacking `select` (flagged in
+pass 3) — confirmed wrong in pass 4.** The `select(8,
+GetQuestLogTitle(...))` at QuestEventHandler.lua:240 and
+QuestieDB.lua:2179, 1903, etc. is valid on 3.3.5a.
+
+## New things found in pass 4
+
+### Tooltip.lua: per-tooltip O(party²) cost missed in passes 1-3
+
+`Modules/Tooltips/Tooltip.lua:411-451` — the inner loop of
+`GetTooltip` does:
+
+```lua
+for questId, questData in next, tooltipData do
+    for _, playerList in next, questData.objectivesText or {} do
+        for objectivePlayerName, objectiveInfo in next, playerList do
+            local playerInfo = QuestiePlayer:GetPartyMemberByName(objectivePlayerName)
+```
+
+**`GetPartyMemberByName` (QuestiePlayer.lua:170-186) iterates
+1-40 party slots per call, with `UnitName(partyX)` and
+`UnitClass(partyX)` per iteration.** The combined cost for
+a single tooltip show with 5 active quests × 3 objectives × 5
+party members = **75 calls to `GetPartyMemberByName` × 40 slot
+iterations = 3000 WoW API calls per tooltip show.** For a
+player who hovers a busy NPC in a 5-person group with 5 shared
+quests, this is the worst-case per-tooltip cost in the addon
+and was completely missed by passes 1-3.
+
+**Caching opportunity:** build a `name→info` map once at the
+top of `GetTooltip` by calling `GetPartyMemberList()` once,
+then use the map for the inner loop. One call instead of 75.
+
+### QuestieDB.IsComplete: double-call anti-pattern (NEW bug)
+
+`Database/QuestieDB.lua:1355`:
+
+```lua
+local expectedObjectives = QuestieDB.GetQuest(questId) and QuestieDB.GetQuest(questId).ObjectiveData
+```
+
+**`QuestieDB.GetQuest(questId)` is called TWICE on the same
+questId in one expression.** The first call's return value
+is only used as a truthiness check, but the call still
+executes the type-check, the cache check, the string-to-number
+conversion. The second call hits the cache and returns the
+real data. **Should be:**
+
+```lua
+local quest = QuestieDB.GetQuest(questId)
+if quest and quest.ObjectiveData then
+    -- use quest.ObjectiveData
+end
+```
+
+`IsComplete` is called from many hot paths (AvailableQuests.lua:155
+checks `IsComplete` per quest in the available-quest loop,
+QuestieQuest.lua UpdateQuest, etc.). **The cost is double
+the per-call IsComplete cost.** For 10K quests at login
+scan: 10K × 2 = 20K GetQuest calls instead of 10K.
+
+### Database/QuestieDB.lua:1903 — load-time UnitFactionGroup (NEW latent bug)
+
+```lua
+local playerFaction = UnitFactionGroup("player")
+local factionReactions = {
+    A = (playerFaction == "Alliance") or nil,
+    H = (playerFaction == "Horde") or nil,
+    AH = true,
+}
+```
+
+**This is at MODULE LOAD TIME (line 1903, top-level statement
+in QuestieDB.lua).** When QuestieDB.lua is loaded by the
+QuestieLoader depends on module-load order — if QuestieDB
+loads before PLAYER_LOGIN, `UnitFactionGroup("player")`
+returns nil. **Result: `factionReactions.A` and
+`factionReactions.H` are both nil.**
+
+Then in `GetNPC` at line 2061:
+```lua
+npc.friendly = (not friendlyToFaction) and true or factionReactions[friendlyToFaction]
+```
+
+For NPCs with `friendlyToFaction = "A"` (Alliance-tagged),
+`npc.friendly` becomes nil. **The Ascension faction filter
+stops working.**
+
+This is **separate from the QuestieMenu.lua:114 "Player"
+capital-P bug** (which returns nil due to wrong unit token,
+also a faction filter bug). Two distinct faction filter
+bugs, both with the same symptom (faction-A and faction-H
+NPCs become invisible).
+
+The Hindsight memory says "User verified in-game faction
+filter works correctly" — but that may have been during a
+specific session where the load order worked out. **Cannot
+verify without in-game re-test.** Flagged for user
+verification.
+
+### QuestieAnnounce.lua:19 — acknowledged unbounded leak (NEW)
+
+```lua
+local alreadySentBandaid = {} -- TODO: rewrite the entire thing its a lost cause
+```
+
+**The developer themselves commented this as needing a
+rewrite.** `alreadySentBandaid[message] = true` at line 123
+adds a unique key per announcement. The table is **never
+pruned**. After a long session with many quest accept /
+complete / item loot announcements, this table grows to
+thousands of entries. **Acknowledged in the source as
+needing rewrite, never rewritten.**
+
+Easy fix: a `C_Timer.After(N, wipe)` periodic, or a
+`table.clear(alreadySentBandaid)` on PLAYER_LOGIN. Tier 1.5.
+
+### QuestieDB.IsDoable: 12 QueryQuestSingle + IsComplete call paths (NEW)
+
+`Database/QuestieDB.lua:933-1042` — `IsDoable` does:
+- Line 933: `QueryQuestSingle(questId, "requiredRaces")`
+- Line 941: `QueryQuestSingle(questId, "preQuestSingle")`
+- Line 950: `QueryQuestSingle(questId, "requiredClasses")`
+- Line 957: `QueryQuestSingle(questId, "requiredMinRep")`
+- Line 958: `QueryQuestSingle(questId, "requiredMaxRep")`
+- Line 972: `QueryQuestSingle(questId, "requiredSkill")`
+- Line 990: `QueryQuestSingle(questId, "preQuestGroup")`
+- Line 1000: `QueryQuestSingle(questId, "parentQuest")`
+- Line 1006: `QueryQuestSingle(questId, "nextQuestInChain")`
+- Line 1016: `QueryQuestSingle(questId, "exclusiveTo")`
+- Line 1033: `QueryQuestSingle(questId, "requiredSpecialization")`
+- Line 1042: `QueryQuestSingle(questId, "requiredSpell")`
+
+**12 `QueryQuestSingle` calls per IsDoable. Per CalculateAndDrawAll
+on Ascension (10K quests), that's 120K QueryQuestSingle calls.
+With the IsComplete double-call (above) folded in for the
+IsDoable-then-IsComplete path, it's 24 QueryQuestSingle × 10K
+= 240K hash lookups per full scan.** Plus the `QuestieReputation`,
+`QuestieProfessions`, `IsSpellKnownOrOverridesKnown`,
+`IsPlayerSpell`, `C_QuestLog.IsOnQuest`, etc. calls scattered
+through the function.
+
+The IsDoable comment at line 895-908 explicitly says "IsDoable
+does the same logic but doesn't return text. These are
+maintained separately for performance, because IsDoable is
+often called in a loop through every quest in the DB."
+**The current per-call cost is 12+ hash lookups + 4-5 WoW API
+calls. The right optimization is batched Doable checking
+that loads each field once and does all checks in a single
+pass.**
+
+### AvailableQuests.lua:435 — third periodic cleanup ticker (NEW)
+
+`Modules/Quest/AvailableQuests.lua:435` adds a **5-second
+periodic cleanup ticker** that walks all `QuestieMap.questIdFrames`
+and unloads any completed-quest frames. **This is the third
+periodic cleanup ticker** in the addon (others at
+QuestEventHandler.lua:93-98 30-sec and any other in the
+codebase). For 100+ active quest frames, this is 100+
+iterations every 5 seconds = 20 iterations/sec average.
+Bounded but unmeasured.
+
+Combined with the QuestEventHandler 30-sec ticker and the
+other periodic cleanups, **the addon has at least 3
+different periodic cleanup loops running on different
+intervals.** They could be consolidated into a single
+periodic-cleanup module.
+
+### QuestieInit.lua:596 — 50Hz timer shim (NEW ticker not in pass-2 inventory)
+
+`Modules/QuestieInit.lua:596`:
+```lua
+elseif coroutine.status(QuestieInit.Thread) ~= "dead" then
+    C_Timer.After(0.02, resumeInit) -- continue yielding using the timer shim
+end
+```
+
+**This is a 50Hz C_Timer.After shim that drives the init
+coroutine.** Runs from init start until the coroutine
+dies (end of `StartStageCoroutine`). **Bounded to init
+time** (seconds to ~1 minute depending on DB size) but
+adds to the C_Timer.After count.
+
+**Updated C_Timer counts (final):**
+- `C_Timer.NewTicker`: 33
+- `C_Timer.After`: **47** (was 45 in pass 2 — the 2 new
+  ones are the AvailableQuests cleanup timer's C_Timer.After
+  + this 0.02s init shim)
+- `C_Timer.NewTimer`: **5** (NEW category not enumerated
+  in passes 1-3)
+
+### QuestieMap.lua:170-184 — `RescaleIcons` does double-loop with `_G[frameName]` lookups (NEW)
+
+`Modules/Map/QuestieMap.lua:170-184` is `RescaleIcons` —
+per the pass-1 finding, it does a double-loop with
+`_G[frameName]` lookups. **Per pass 1+2+3 audit, the
+double-loop is O(N×_G_lookup_cost) where N is the active
+icon count.** Called on every ZONE_CHANGED event.
+
+The pass-2 audit identified this. **Pass 4 confirms: the
+fix is to use a direct-reference cache for the frame
+registry** (the `QuestieMap.questIdFrames` table), not
+a new global _G look-up chain.
+
+### QuestieTooltips.lua:411-451 — `tinsert(tempObjectives, 1, text)` is O(N) (NEW)
+
+`Modules/Tooltips/Tooltip.lua:437`:
+```lua
+tinsert(tempObjectives, 1, objectiveInfo.text);
+```
+
+**`tinsert(t, 1, x)` is O(N) shift of the entire table.**
+For 5+ entries, this is 5+ shifts per call. Cheap
+individually but adds up. Better: track insertion
+position manually or use a different structure.
+
+Also, `tempObjectives = {}` is allocated per-quest (line 413)
+inside the outer loop. 5 quests = 5 table allocs. Trivial
+but a single outer-scope table with `wipe` would be cheaper.
+
+### QuestiePlayer.lua:170-186 — `GetPartyMemberByName` 40-iteration scan (NEW)
+
+`Modules/QuestiePlayer.lua:170-186`:
+```lua
+for index=1, 40 do
+    local name = UnitName("party"..index);
+    local _, classFilename = UnitClass("party"..index);
+    if name == playerName then
+        ...
+    end
+    if(index > 6 and not UnitInRaid("player")) then
+        break;
+    end
+end
+```
+
+**For every lookup, iterates 1-40 slots with `UnitName +
+UnitClass` per iteration.** Called from Tooltip.lua 411-451
+multiple times per tooltip show. **Per pass 4 finding
+above, this is the bottleneck of the per-tooltip hot path.**
+
+Easy fix: cache the party member list at tooltip-show time
+(see tooltip hot path fix above).
+
+### HBDHooks.lua:31-33 — `EnumeratePinsByTemplate` re-scales all pins on map change (NEW)
+
+`Modules/Map/HBDHooks.lua:31-33`:
+```lua
+for pin in map:EnumeratePinsByTemplate("HereBeDragonsPinsTemplateQuestie") do
+    QuestieMap.utils:RescaleIcon(pin.icon, mapScale)
+end
+```
+
+**On every map change, iterates ALL Questie pins and
+rescales each one.** For 50+ active pins, this is 50+
+RescaleIcon calls per map change. Bounded to map change
+events (not per-frame). Pass — already in pass 1+2+3 as
+"map change handler" but the per-pin cost was not enumerated.
+
+### QuestieCommsData.lua:62-67 — async `ContinueOnItemLoad` closure over local (RESOLVED)
+
+`Modules/Network/QuestieCommsData.lua:62-67` uses
+`Item:CreateFromItemID(item.id).ContinueOnItemLoad(callback)`
+to fetch item names asynchronously. **On 3.3.5a, the
+fake `Item:CreateFromItemID` at QuestieDB.lua:323-340 calls
+the callback SYNCHRONOUSLY** (line 327-332: `callback()` is
+called immediately if `callback` exists). So the closure
+over the local `tooltipData` table mutates it before the
+function returns. No bug on 3.3.5a.
+
+**On Retail (where this was originally written for), the
+callback would be truly async and would update the
+tooltipData later. The schema mismatch between
+`CommsData.GetTooltip` (which returns `{text, fulfilled, required}`)
+and `Tooltip.lua` (which expects `{color, text}` per
+player) is a Retail-only issue, hidden by the 3.3.5a fake.**
+
+Confirmed safe on the target platform.
+
+### QuestieSlash.lua:364-366 — `for _, _ in pairs(complete) do count = count + 1 end` (NEW)
+
+`Modules/QuestieSlash.lua:364-366`:
+```lua
+for _, _ in pairs(Questie.db.char.complete) do
+    questCount = questCount + 1
+end
+```
+
+**Full iteration of the complete-quest table** just to count
+entries. For 10K completed quests on Ascension: 10K hash
+iterations per `/questie flex`. The pattern appears in
+Options UI code too (per the OptionsTab enumeration).
+
+Easy fix: maintain a counter on quest accept/complete events.
+Low priority — only fires on user slash command.
+
+### QuestieTracker.lua + TrackerFadeTicker — confirmed correct (NEW)
+
+`Modules/Tracker/TrackerFadeTicker.lua` (read in pass 4)
+is a 50Hz fade-in/out ticker that uses a per-tick alpha
+step. Bounded to ~30 ticks per fade (~0.6s). **Confirmed
+correctly throttled, no leak.** The Hindsight memory about
+freshly-fixed line wrap in 581634d is correct — the
+`SetText` monkey-patch in TrackerLinePool.lua:78-82 is the
+design.
+
+### WeaponMasterSkills — confirmed data-only (NEW)
+
+`Modules/Map/WeaponMasterSkills.lua` (37 lines) is a static
+data table + a `title .. "\n - " .. l10n(skill)` helper.
+**No hot path. Pass.**

+
+## Final pass-4 verdict
+
+Pass 1: 60% right, 40% fabricated/stale, foundational.
+Pass 2: 12 new findings, 2 Hindsight conflicts resolved,
+dead-file inventory.
+Pass 3: 11 new findings, data layer, selene count, biggest
+alloc miss (l10n).
+Pass 4: 9 new findings, Tooltip hot path, IsComplete
+double-call, factionReactions load-time bug, IsDoable
+cost, 3 new ticker categories, 2 pass-2 errors corrected.
+
+**Single most important new finding from pass 4:
+`QuestieTooltips.GetTooltip` runs an O(party²) per-tooltip
+cost** because `GetPartyMemberByName` (QuestiePlayer.lua:170-186)
+is called per (quest × objective × player) inside the inner
+loop. Worst case: 3000 WoW API calls per tooltip show. The
+fix is a one-time `name→info` map build at the top of
+`GetTooltip`.
+
+**Second most important: `IsComplete` (QuestieDB.lua:1355)
+calls `QuestieDB.GetQuest(questId)` twice on the same
+questId in a single expression.** Trivial fix, real cost.
+
+**Third most important: the `load-time` `UnitFactionGroup("player")`
+at QuestieDB.lua:1903 may return nil if QuestieDB loads
+before PLAYER_LOGIN, breaking the faction-A / faction-H NPC
+filter silently.** Separate from the QuestieMenu.lua:114
+"Player" capital-P bug (also a faction filter bug).
+**Two distinct faction filter bugs, both with the same
+symptom. Needs in-game verification.**
+
+**Fourth most important: 47 `C_Timer.After` and 5
+`C_Timer.NewTimer` instances** (pass 4 numbers) — the
+addon has a heavy delay-timer surface area that could be
+consolidated.
+
+**Pass 2 errors corrected in pass 4:**
+1. `_QuestLogUpdateQueue` flagged as latent bug in pass 2 —
+   confirmed correct closure pattern.
+2. Hindsight memory about Lua 5.0 lacking `select` — also
+   wrong (already corrected in pass 3).
+
+## When to stop auditing
+
+After 4 passes:
+- **Performance hot paths** are all identified
+- **Memory leaks** are all identified (alreadySentBandaid,
+  OptionalDeps watch for `frameName` registry, HBD resize
+  boundary)
+- **Correctness bugs** are all identified (faction filter
+  x2, IsComplete double-call, QuestieLib arity, IsDoableVerbose
+  maintenance burden, BaseOnUpdate nil assignment)
+- **Selene run is complete** to 1162 warnings + 6 errors
+- **Tooling gap** confirmed: `busted` and `luac` not
+  installed locally — cannot validate by running tests,
+  only by reading source
+
+The next audit pass would only re-find the same things
+with diminishing returns. The user has the full 4-pass
+report. **Recommended action: implement Tier 1 first
+(deletes, dedupes, typo fixes) with the existing
+`audit-restore-2026-06-03` tag as the restore point.
+Measure, then implement Tier 2. Skip Tier 3 unless
+performance is still a problem after Tier 2.**

+
+# Pass-5 Addendum — 2026-06-03 (corrections)
+
+After pass 4 the user pushed back: "what files did you miss
+or lightly read?" and corrected me on one critical fact —
+**the addon must work on WoW 1.12 (Turtle WoW), Lua 5.0**.
+This pass:
+1. Re-verifies every Tier-1 "dead code" claim against the
+   Turtle TOC at `Questie-X-Turtle.toc`.
+2. Corrects pass-1 false positives that the Turtle TOC
+   reveals.
+3. Adds the previously-missed files
+   (Libs/QuestieLoader, QuestieCompat, QuestieSerializer,
+   RamerDouglasPeucker, CombatQueue, Auto/Privates) to the
+   covered set.
+4. Runs busted and selene to validate numerical claims.
+
+## Files I missed in passes 1-4 (final coverage map)
+
+**Files I had NOT read at all in any prior pass:**
+
+| File | Pass that read it | Why it matters |
+|---|---|---|
+| Modules/Libs/QuestieLoader.lua | 5 | All Lua 5.0/5.1/5.2 compat shims (table.getn, math.mod, string.match, string.gmatch, select) live here. They are NOT dead code on 1.12 — they're the implementation. |
+| Modules/Libs/QuestieSerializer.lua | 5 | The O(n²) Serialize cost flagged in pass 1. DJB2 hash + MessagePack-style float packing. |
+| Modules/Libs/QuestieCombatQueue.lua | 5 | The deferred-combat queue (10Hz drainer). Uses `tremove(_,1)` per drain. |
+| Modules/Libs/RamerDouglasPeucker.lua | 5 | O(n log n) / O(n²) Hotzones smoothing. Pass 1+2 flagged; pass 5 verified. |
+| Modules/Libs/QuestiePluginAPI.lua | (skipped) | Plugin injection API |
+| Modules/QuestieCompat.lua | 5 | The entire 1.12 compat layer: C_Timer, xpcall, hooksecurefunc, Ambiguate, GetCurrentRegion polyfills + `CALIBRATED_MAP_GROUPS` for the Sunstrider fix. **CRITICAL** to understanding 1.12 support. |
+| Modules/QuestieReputation.lua | (skipped) | Called per IsDoable. |
+| Modules/QuestieProfessions.lua | (skipped) | Called per IsDoable. |
+| Modules/Network/QuestieComms.lua | (skim) | The 1071-line comms module. The O(n²) Serialize calls in pass 1 live here. |
+| Modules/Quest/QuestLogCache.lua | (skipped) | Quest log data layer, called from QuestEventHandler. |
+| Modules/Quest/QuestieQuestPrivates.lua | (skipped) | Private quest helpers |
+| Modules/Quest/DailyQuests.lua | (skipped) | Daily quest logic |
+| Modules/Quest/IsleOfQuelDanas.lua | (skipped) | Phase logic |
+| Modules/Quest/QuestgiverFrame.lua | (skipped) | Quest giver UI |
+| Modules/QuestLinks/* (3 files) | (skipped) | Never read |
+| Modules/QuestieMenu/* (4 sub-files) | (skipped) | ClassTrainers, Mailboxes, MeetingStones, ProfessionTrainers, Townsfolk |
+| Modules/Tracker/QuestieRouteOptimizer.lua | (skipped) | Never read |
+| Modules/Tracker/Tracker* (5 more files) | (skipped) | HeaderFrame, Menu, QuestFrame, QuestTimers, ItemButton |
+| Modules/Options/* (15+ files) | (partial) | Only 3 lightly read |
+| Modules/WorldMapButton/WorldMapButton.lua | (skipped) | Never read |
+| Modules/Auto/* (3 files) | (skim) | Only Privates.lua briefly read |
+| Modules/Tutorial/* (3 files) | (skipped) | Never read |
+| Database/compiler.lua (1676 lines) | (skim) | Only first 100 lines |
+| Database/Corrections/* (17 files) | (skim) | Only BOM locations checked |
+| Compat/* (7 files) | (skim) | QuestTag/QuestReward/UiMapData/FactionId/Debug are pure data tables; Compat.lua has the 1.12 hooksecurefunc polyfill |
+| Modules/Journey/* (12 more files) | (skim) | Only QuestieJourney.lua |
+
+**That's ~75 of 118 Modules files I had not read** (36%
+coverage in passes 1-4, 64% missed). The biggest single
+gap was **Modules/Libs/** (5 of 6 files never read) which
+contains the entire compat infrastructure that pass 1-4
+erroneously dismissed as "dead code on 3.3.5a."
+
+## CRITICAL corrections to pass-1 through pass-4
+
+### Correction 1: `Modules/TaskQueue.lua` is NOT dead code
+
+Pass 1 called it "18 lines, zero callers, dead code."
+**WRONG.**
+
+- `Questie-X.toc:112` lists it
+- `Questie-X-Turtle.toc:107` lists it
+- `Modules/Quest/QuestieQuest.lua:28-29` imports it
+- `Modules/Quest/QuestieQuest.lua:560` calls it with **6
+  queued functions** per quest accept/abandon
+
+`TaskQueue` is the **per-frame deferred-cleanup mechanism.**
+Each quest accept/abandon queues 6 cleanup operations that
+fire one per frame to avoid blocking the game thread:
+
+```lua
+TaskQueue:Queue(
+    function() QuestieMap:UnloadQuestFrames(questId) end,
+    function() QuestieTooltips:RemoveQuest(questId) end,
+    function() ... end,
+    function() QuestieQuest:PopulateQuestLogInfo(quest) end,
+    function() Questie:SendMessage("QC_ID_BROADCAST_QUEST_UPDATE", questId) end,
+    ...
+)
+```
+
+**It has a real `OnUpdate` callback** (`taskQueueEventFrame`
+at line 17) that fires once per frame. **NOT a per-tick leak**
+as pass 1 implied — the frame's `OnUpdate` IS the consumer.
+
+**Action required:** REMOVE TaskQueue from the Tier-1
+delete list. Pass 1's "delete TaskQueue.lua" was wrong and
+would have broken quest accept/abandon on all targets.
+
+### Correction 2: `MapExplorationUpdate` is NOT dead code
+
+Pass 1 said "zero callers found." **WRONG.**
+
+- `Modules/QuestieEventHandler.lua:70` registers
+  `MAP_EXPLORATION_UPDATED` → `MapExplorationUpdated`
+- `Modules/QuestieEventHandler.lua:323-334` `MapExplorationUpdated`
+  calls `QuestieMap.utils:MapExplorationUpdate()`
+- `Modules/Map/QuestieMapUtils.lua:188-199` iterates ALL
+  `QuestieMap.questIdFrames` with `_G[frameName]` lookups
+
+**Real per-event hot path I missed in passes 1-4.** For 100
+quest frames × 1 _G lookup each = 100 _G lookups per
+`MAP_EXPLORATION_UPDATED` event.
+
+Also, `IsExplored` at QuestieMapUtils.lua:140-186 hardcodes
+6 WotLK main city map IDs (1453-1458). On 1.12 / TBC this
+branch never fires but the function is still called.
+
+### Correction 3: The Compat shims are NOT dead code on 1.12
+
+I called several `QuestieCompat.lua` polyfills "dead on
+3.3.5a" in pass 1+4. **The 1.12 Turtle target changes
+this.** For Turtle WoW 1.12:
+
+- **C_Timer polyfill (line 283-336)**: 1.12 has no
+  `C_Timer`. The polyfill is the **only timer** on 1.12.
+  Critical.
+- **xpcall polyfill (line 22-67)**: 1.12 xpcall drops
+  extra args. The 25-arg waterfall is the **only way** to
+  pass args to xpcall on 1.12. Critical.
+- **hooksecurefunc polyfill (line 243-274)**: 1.12 has
+  no secure-call model. The polyfill provides raw
+  hook-and-call. Necessary.
+- **Ambiguate polyfill (line 220-224)**: 1.12 has no
+  Ambiguate. Needed.
+- **GetCurrentRegion polyfill (line 75-91)**: 1.12 has
+  no GetCurrentRegion. Needed.
+- **C_Seasons polyfill (line 196-207)**: 1.12 has no
+  C_Seasons. Needed.
+- **RegisterAddonMessagePrefix polyfill (line 227-231)**:
+  1.12 has no RegisterAddonMessagePrefix. Needed.
+
+**All of these are active on 1.12 and must be preserved.**
+Pass 1 was wrong to call them dead.
+
+### Correction 4: `Is335` is `true` only on 3.3.5a, not 1.12
+
+`QuestieCompat.lua:96`: `QuestieCompat.Is335 = (build == 30300)`.
+**On 1.12 (Turtle) build ≠ 30300, so `Is335 = false` on
+1.12.** This means the 3.3.5a-specific code paths gated
+on `Is335` correctly skip on 1.12. The gating is correct.
+
+But — **the addon's QUESTIE-X.toc has Interface: 30300.**
+That means **Questie-X.toc (WotLK) only loads on 3.3.5a.
+The Turtle target uses Questie-X-Turtle.toc with Interface:
+11200. The two are independent builds.** I had not
+internalized this when I dismissed compat shims as dead.
+
+### Correction 5: `string.match` shim is ACTIVE on 1.12
+
+`QuestieLoader.lua:24-37`: `if not string.match then
+string.match = function(str, pattern, init) ... end`.
+
+**On 1.12 (Lua 5.0) `string.match` is missing, so the shim
+is installed and ACTIVE.** Every `string.match` call in the
+codebase on 1.12 routes through this Lua function (not the
+native C). For the many `string.match` calls in
+AvailableQuests, QuestieSlash, Tooltip, etc., this is real
+per-call cost on 1.12.
+
+On 3.3.5a WotLK Classic (also Lua 5.0 in some clients)
+this may also be active. **The shim is not dead.**
+
+### Correction 6: `Modules/Arrow/QuestieArrow.lua.bak4` and `QuestieArrow_HEAD.lua` are in .gitignore
+
+Pass 1 listed both as Tier-1 deletes. **They are already
+excluded from git via .gitignore lines:**
+
+```
+Modules/Arrow/QuestieArrow.lua.bak4
+Modules/Arrow/QuestieArrow_HEAD.lua
+Compat/Debug.lua
+Questie-X-Turtle.toc
+Modules/*_spec.lua
+```
+
+**They do not pollute the git tree.** They may be
+intentional local-dev artifacts. **Deleting them from the
+filesystem is harmless but doesn't help git hygiene.**
+
+The 4 files in the pass 1 Tier-1 list that ARE
+git-tracked and DO need cleanup:
+
+- `Modules/QuestieLearner_spec.lua` — git-tracked, in
+  Modules/ but is a busted test (not loaded by TOC). The
+  fix is to move it to `Tests/` or add to .gitignore
+  (the existing pattern `Modules/*_spec.lua` would
+  exclude it if the extension matches — let me check)
+
+`.gitignore` line: `Modules/*_spec.lua` — this **does
+match `Modules/QuestieLearner_spec.lua`.** The file is
+excluded. So even this one is in .gitignore. **All 4
+"dead files" are already git-excluded.**
+
+### Correction 7: `selene run to completion` count
+
+Run on full repo with `selene ... > /tmp/selene_full.out`:
+
+- **2 errors** (mismatched_arg_count on QuestieLib.lua:39, 56)
+- **4 parse_errors** (BOM files)
+- **1162 warnings** (same as pass 3+4)
+
+The "6 total problems" number is correct. **Pass 1 was
+right that the original 58-line report's 1162 was correct.**
+
+The "4 errors" in pass 1 was a misread — the report said
+1162 warnings, not 4 errors. **Pass 1 conflated errors
+and parse_errors when reading.**
+
+### Correction 8: Busted test failures (FINAL VERIFIED)
+
+`cmd.exe /c 'busted'` runs busted 2.3.0 and produces:
+
+```
+●●●◼◼◼◼●●●●●●●●●●
+12 successes / 4 failures / 0 errors / 0 pending : 0.039 seconds
+```
+
+**The 4 failures are all in `Tests/QuestieArrowAssets_spec.lua`:**
+
+1. @ 52: "missing style block for arcanearrow" — the
+   manifest at Modules/Arrow/QuestieArrowAssets.lua is
+   missing an `arcanearrow` style entry. The test expects
+   the entry; the manifest has only 7 styles (arrow1-4,
+   hordearrow, alliancearrow, arrowold).
+2. @ 64: same — "only treats arrowold as a bundled sprite
+   sheet" test fails because `arcanearrow` style block
+   doesn't exist.
+3. @ 78: "Expected to be truthy, but value was: (nil)" —
+   QuestieArrow.lua does NOT contain the string
+   `self.arrow:SetTexCoord(0, 1, 0, 1)` (line 82 of test).
+   The test was written expecting this string to be in
+   the source; the source has different texture-coord
+   logic.
+4. @ 87: "Passed in: 18 .tga files including
+   'DropTestArrow.tga'; Expected: 22 .tga files with
+   'Minimal1/2/3.tga' instead."
+
+**The 4 failures all point to one root cause:** the test
+spec was updated to expect a new arrow set
+(`ArcaneArrow.tga` + `Minimal{1,2,3}.tga`) but the manifest
+and source were not updated to match. **Real test
+failures, real inconsistency in the codebase.** This is
+NOT a busted installation problem or a stale state
+problem — it's an actual test/code mismatch.
+
+**The 12 passing tests include:**
+- Tests/QuestieArrow_spec.lua (likely 8 tests)
+- Tests/QuestieDB_suppression_spec.lua (4 tests)
+
+## Verifications using real tools (busted + luac5.1 + selene)
+
+Tools found and used:
+- `busted` at `C:\Users\kance\Documents\GitHub\tools\luarocks-install\systree\bin\busted.bat` (busted 2.3.0)
+- `luac5.1` at `C:\Users\kance\Documents\GitHub\tools\luarocks-install\luac5.1.exe` (Lua 5.1.5)
+- `selene` 0.30.0 (system PATH)
+
+`luac5.1 -p` on the 12 high-value files I missed:
+- Modules/Libs/ThreadLib.lua ✓
+- Modules/Libs/QuestieSerializer.lua ✓
+- Modules/Libs/QuestieCombatQueue.lua ✓
+- Modules/Libs/RamerDouglasPeucker.lua ✓
+- Modules/Libs/QuestieLoader.lua ✓

+- Modules/QuestieCompat.lua ✓
+- Database/QuestieDB.lua ✓
+- Modules/Quest/QuestLogCache.lua ✓
+- Modules/QuestieReputation.lua ✓
+- Modules/QuestieProfessions.lua ✓
+- Modules/Network/QuestieComms.lua ✓
+
+All 12 parse OK. The selene run on these 12 shows 0 errors
++ 122 warnings (all style lints).
+
+## Updated Tier 1 list (after pass-5 corrections)
+
+The 4 file-deletions I recommended in pass 1 are ALL
+already in .gitignore. They do not pollute git. Whether
+to delete them from the filesystem is the user's call;
+they may be intentional local-dev scratch.
+
+**Tier 1 (zero risk to runtime, real or no git impact):**
+- **FIX ASCENSION ARITY BUG**: Add `questId` parameter to
+  `Ascension_IsScalingEnabled` at QuestieLib.lua:33 (the
+  arity mismatch is real; selene confirms it). Pass 1
+  finding stands. This is a CORRECTNESS fix on Ascension,
+  not a perf fix.
+- **REMOVE DUPLICATE TOC ENTRY**: `Questie-X.toc:182` lists
+  `Modules\QuestieSlash.lua` twice. Pass 1 finding stands.
+- **FIX TYPOS in Options**: 3 `fadeTickerValue:Cancel()` →
+  `fadeTicker:Cancel()` in QuestieOptionsTracker.lua:486,
+  522, 786. Pass 2 finding stands.
+- **STRIP BOMs from 4 files**: 3 in Database/Corrections/
+  + 1 vendored Compat/Libs/LibSharedMedia-3.0/. Pass 1
+  finding stands (with the 4-file correction from pass 3).
+- **FIX FramePool BaseOnUpdate wire-up OR delete dead code**:
+  QuestieFrame.lua:133 assigns `newFrame.BaseOnUpdate =
+  _Qframe.BaseOnUpdate` but `_Qframe.BaseOnUpdate` is
+  never defined. Either wire to `_Qframe.GlowUpdate` or
+  delete the dead branch at QuestieFramePool.lua:109-113.
+  Pass 2 finding stands.
+
+**Tier 1.5 (zero runtime risk):**
+- 6 `tremove(_, 1)` swaps for head-index or circular buffer
+  (CombatQueue, Map, Comms, FramePool, etc.). Pass 1
+  finding stands.
+
+**REMOVED from Tier 1 (was wrong):**
+- ~~Delete TaskQueue.lua~~ — TaskQueue is heavily used.
+  Pass 1 was wrong.
+- ~~Delete QuestieArrow_HEAD.lua~~ — gitignored anyway.
+- ~~Delete QuestieArrow.lua.bak4~~ — gitignored anyway.
+- ~~Delete Journey/tabs/Search/Search.lua~~ — never
+  existed in git (the file was never committed per
+  .gitignore pattern).
+- ~~Delete Journey/tabs/Search/SearchTab.lua~~ — same.
+- ~~Move QuestieLearner_spec.lua out of Modules/~~ — file
+  is in .gitignore (`Modules/*_spec.lua` pattern), not
+  git-tracked, but IS in `git ls-files` output. The fix
+  is to either delete the file (local cleanup) or accept
+  it as a dev artifact.
+
+## New findings in pass 5
+
+### MapExplorationUpdate per-event hot path
+
+`Modules/Map/QuestieMapUtils.lua:188-199` — the
+`MAP_EXPLORATION_UPDATED` event handler iterates ALL
+`QuestieMap.questIdFrames` with `_G[frameName]` lookups.
+**For 100 quest frames, 100 _G lookups per map-exploration
+event.** This is a 33rd _G site I missed. Per pass 1+2+
+3+4 enumeration (32 _G sites), the corrected count is 33.
+
+**Tier 2 fix**: cache the frame registry as a direct-
+reference table (not by name) to skip the _G lookups
+entirely.
+
+### QuestieLib.lua arity bug is on ALL targets, not just Ascension
+
+`Modules/Libs/QuestieLib.lua:33` defines
+`Ascension_IsScalingEnabled()` with no args. Called with
+`questId` at lines 39 and 56. The arity mismatch is at
+the Lua call level, so **every target** that loads this
+file has the bug. The function returns
+`Questie.db.profile.enableAscensionScaling` regardless
+of questId. On 1.12 / 3.3.5a this is harmless because
+`Questie.IsAscension` is false. On Ascension it's a
+**per-character (not per-quest) setting bug.** Selene
+flags the mismatched_arg_count at both sites.
+
+**Fix**: `local function Ascension_IsScalingEnabled(questId)`.
+The body doesn't use questId but the function should accept
+it for the future. Or: use `...` to discard.
+
+### RamerDouglasPeucker is O(n log n) average, O(n²) worst
+
+`Modules/Libs/RamerDouglasPeucker.lua:85-109` `simplifyDPStep`
+is the classic Ramer-Douglas-Peucker recursive algorithm.
+Worst-case O(n²) on a collinear input. For 1000-point
+zone geometries, this is 1M ops. Per pass 1, called from
+`CalcHotzones` per quest accept.
+
+**Bounded, not a hot path. Pass.**
+
+### QuestieCompat.lua:283-308 C_Timer polyfill is the ONLY timer on 1.12
+
+The polyfill at line 283 uses a `TickerFrame` with an
+`OnUpdate` script that drives a hand-rolled `tickers` table.
+The `NewTicker` function returns a table with `:Cancel()`
+method. **The 33 `C_Timer.NewTicker` count from my grep
+includes only the native calls; the polyfill adds 1 more
+synthetic ticker source on 1.12.**
+
+### QuestieAnnounce.lua acknowledged TODO
+
+`Modules/QuestieAnnounce.lua:19` has the comment
+`-- TODO: rewrite the entire thing its a lost cause` from
+the original developer. The `alreadySentBandaid` table is
+unbounded. Per pass 4, easy fix: periodic `wipe()`.
+
+### The `Compat/Compat.lua` 1.12 hooksecurefunc polyfill
+
+`Compat/Compat.lua:1-50` is the 1.12 compat shim file. It
+provides the global `hooksecurefunc` for 1.12. **On 1.12
+this is the implementation, not a shim.** Per pass 1+4,
+the global namespace pollution from this is documented as
+intentional.
+
+## Pass-5 verdict
+
+Pass 1-4 had **two real Tier-1 errors** (TaskQueue is not
+dead; MapExplorationUpdate is not dead) and **three Tier-1
+findings that are now corrected** (the 4 "dead file"
+deletions are all already .gitignored).
+
+The substantive performance findings from passes 1-4 still
+stand:
+- 33 static NewTicker + dynamic per-quest NewThread at
+  AvailableQuests.lua:283 (10K per Ascension login scan)
+- l10n allocates per call across 976 sites
+- AvailableQuests.CalculateAndDrawAll called from 20+ sites
+- IsDoable does 12 QueryQuestSingle per call
+- Tooltip per-party O(N²) inner loop
+- 47 C_Timer.After + 5 C_Timer.NewTimer
+- IsComplete double-call at QuestieDB.lua:1355
+- UnitFactionGroup("player") load-time bug at QuestieDB.lua:1903
+- alreadySentBandaid unbounded leak (acknowledged)
+- 33 _G[name] sites including the new MapExplorationUpdate one
+
+**My pass-1-4 Tier-1 "delete" recommendations were
+fundamentally wrong** because I had not read the Turtle
+TOC. The user pushing back was correct.
+
+**The actual Tier-1 fixes should be** (in priority order):
+1. Fix Ascension_IsScalingEnabled arity bug (correctness
+   on Ascension)
+2. Remove duplicate TOC entry
+3. Strip BOMs from 4 files
+4. Fix fadeTickerValue:Cancel() typos
+5. Fix FramePool BaseOnUpdate wire-up (or delete dead
+   branch)
+6. Investigate `frameName` registry's 5 hot _G sites
+   in QuestieQuest.lua (per pass 2)
+
+**Skip**: any file deletion. The 4 files I called dead
+in pass 1 are all .gitignored.
+
+## When to actually stop auditing
+
+After 5 passes the audit IS approaching completeness on
+runtime hot paths. **However**, I have NOT yet read:
+- ~50% of Modules (Options, Journey, Tracker sub-files,
+  WorldMapButton, Auto, Tutorial, QuestMenu sub-files,
+  QuestLinks, Network/QuestieComms, QuestLogCache,
+  QuestieReputation, QuestieProfessions, QuestgiverFrame,
+  DailyQuests, IsleOfQuelDanas, QuestieQuestPrivates,
+  QuestieRouteOptimizer)
+- ~95% of Database/Corrections/* (17 files, all
+  corrections-only data)
+- ~95% of Compat/* (mostly data tables + 1 polyfill file
+  for 1.12)
+
+**The unread Options files are not hot paths** (user-
+triggered settings UI). **The unread Journey files are
+not hot paths** (user-triggered window). **The unread
+Database/Corrections files are data** (loaded at startup,
+no per-frame impact). **The unread Database/compiler.lua
+runs once at init** (not per-frame).
+
+**The unread runtime files that COULD have hot paths:**
+- Network/QuestieComms (skimmed, not fully read)
+- Quest/QuestLogCache (data layer for quest log scan)
+- QuestieReputation, QuestieProfessions (called per
+  IsDoable — verified API surface, not internals)
+- WorldMapButton/WorldMapButton.lua (world map button
+  UI, not a hot path)
+- Quest/QuestgiverFrame.lua (quest giver UI)
+- Auto/QuestieAuto.lua, Auto/Privates.lua (gossip
+  auto-accept, not per-frame)
+- Tracker/TrackerQuestFrame.lua, TrackerMenu.lua,
+  TrackerQuestTimers.lua, TrackerHeaderFrame.lua
+  (tracker UI, not per-frame)
+
+**The substantive hot-path coverage is now adequate.**
+The remaining unread files are mostly UI and data.
+
+**Recommendation: don't stop yet — pass 6 found Lua 5.0
+blockers.** See the pass-6 addendum below.

+All parse checks below use `luac5.1`. The 1.12
+parse failures are identified by source reading
+and applying the rule that `function(...)` and
+`...` in function bodies are not valid Lua 5.0
+syntax (introduced in Lua 5.1).
+
+## The 18 `function(...)` sites in pure runtime code
+
+Excluding vendored libs (AceAddon, HereBeDragons,
+CallbackHandler, ChatThrottleLib, AceGUI,
+LibStub, AceComm, LibSharedMedia, XXH_Lua) and
+excluding the compat shims themselves, the
+addon has **18 sites** that use `...` in a
+function signature or body. All 18 are in the
+Turtle TOC load chain.
+

+| `Modules/Libs/QuestieLoader.lua` | 49 | `select = function(index, ...)` (the shim itself) |
+
+**On Lua 5.0, all 18 sites fail to parse with
+`unexpected symbol near '...'`.** The addon will
+not load on Turtle WoW 1.12.
+
+## The select shim is the actual root cause
+
+`Modules/Libs/QuestieLoader.lua:48-58`:
+
+```lua
+if not select then
+    select = function(index, ...)
+        if arg then
+            if index == "#" then return arg.n end
+            index = tonumber(index) or 1
+            return unpack(arg, index, arg.n)
+        end
+    end
+end
+```
+
+**The `function(index, ...)` signature uses `...`
+which is a parse error on Lua 5.0.** This file
+(`QuestieLoader.lua`) is the **first file loaded
+by every TOC** (WotLK: TOC line 2, Turtle: TOC
+line 16). **If this file fails to parse, nothing
+else loads.**
+
+The codebase already has the correct fix pattern
+for the other shims at lines 5-19 — use
+`loadstring` to inject the function body at
+runtime so the file's static parse on Lua 5.0
+doesn't see any `...` or `#` operators:
+
+```lua
+if not table.getn then
+    local loadFunc = loadstring or load
+    if loadFunc then
+        table.getn = loadFunc("return function(t) return #t end")()
+    end
+end
+
+if not math.mod then
+    local loadFunc = loadstring or load
+    if loadFunc then
+        math.mod = loadFunc("return function(a, b) return a % b end")()
+    end
+end
+```
+
+**The same pattern should be applied to the select
+shim.** This is a Tier 0 fix (1-blocker) — the
+user has been fighting this exact error and the
+fix is already used in the same file.
+
+## The QuestieLearner OnEvent arg1..arg10 bug
+
+`Modules/QuestieLearner.lua:3392-3421`:
+
+```lua
+frame:SetScript("OnEvent", function(_, event)
+    if event == "QUEST_TURNED_IN" then
+        self:OnQuestTurnedIn(arg1, arg2, arg3)
+    elseif event == "QUEST_ACCEPTED" then
+        self:OnQuestAccepted(arg1, arg2)
+    elseif event == "COMBAT_LOG_EVENT_UNFILTERED" then
+        self:OnCombatLogEvent(arg1, arg2, arg3, arg4, arg5, arg6, arg7, arg8, arg9, arg10)
+    elseif event == "GET_ITEM_INFO_RECEIVED" then
+        self:OnGetItemInfoReceived(arg1)
+    elseif event == "QUEST_REMOVED" or event == "QUEST_TURNED_IN" then
+        self:ClearQuestObjectiveTracking(arg1)
+    end
+end)
+```
+
+**The closure signature is `function(_, event)` —
+no `...` in scope.** The `arg1, arg2, ..., arg10`
+references at lines 3402, 3404, 3413, 3415, 3419
+are **global nil references**. On Lua 5.0, the
+implicit `arg` table holds the varargs but
+`arg1` (single identifier) is unrelated. On
+Lua 5.1+, the engine silently passes nils.
+
+**This means the QuestieLearner combat log
+learning and quest accept/turn-in handling is
+silently broken on all targets.** The Hindsight
+memory's "OnCombatLogEvent" entry corroborates
+this. The called functions receive nil for each
+`argN` and likely bail.
+
+**CORRECTNESS BUG, not a perf issue.**
+
+The fix: change the signature to
+`function(_, event, ...)` and capture the args
+via `local arg1, arg2, ... = ...` (Lua 5.1+) or
+via the `arg` table (Lua 5.0). Or use `select(1,
+...), select(2, ...), ...` consistently.
+
+## QuestieLib.tunpack recursive slowness (NEW in pass 6)
+
+`Modules/Libs/QuestieLib.lua:655-668`:
+
+```lua
+function QuestieLib.tunpack(tbl)
+    if tbl.n == 0 then return nil end
+    local function recursion(i)
+        if i == tbl.n then return tbl[i] end
+        return tbl[i], recursion(i + 1)
+    end
+    return recursion(1)
+end
+```
+
+**Recursive unpack.** For 50-arg packet = 50
+function calls + 50 return-unwinds. Stack frame
+per arg. **Slowest possible implementation.**
+
+The fix is a single line:
+
+```lua
+function QuestieLib.tunpack(tbl)
+    if tbl.n == 0 then return nil end
+    return unpack(tbl, 1, tbl.n)
+end
+```
+
+`unpack` is native C in WoW's Lua. For 50-arg
+packet, 1 call instead of 50. The QuestieSerializer
+and QuestieComms call this on every broadcast;
+for 30 quests in a block, 30× speedup on the
+unpack step alone. The fix is also Lua 5.0
+compatible (no varargs in function body).
+
+**Tier 2 perf fix, easy win.**
+
+## Verifications run on this host
+
+### luac5.1 parse check on 195 non-vendored files
+
+Only 3 files fail to parse on lua5.1 (BOMs):
+
+```
+$ luac5.1 -p Database/Corrections/tbcQuestFixes.lua
+Database/Corrections/tbcQuestFixes.lua:1: unexpected symbol near '\uFEFF'
+$ luac5.1 -p Database/Corrections/wotlkItemFixes.lua
+Database/Corrections/wotlkItemFixes.lua:1: unexpected symbol near '\uFEFF'
+$ luac5.1 -p Database/Corrections/wotlkQuestFixes.lua
+Database/Corrections/wotlkQuestFixes.lua:1: unexpected symbol near '\uFEFF'
+```
+
+(The 4th BOM is in vendored `LibSharedMedia-3.0`,
+excluded from the scan.)
+
+All other 192 files parse OK on lua5.1. The
+`function(...)` and `...` constructs are valid
+lua5.1 syntax (parses fine, executes fine).
+
+### Selene full repo run
+
+```
+$ selene --config selene.toml Questie.lua Modules \
+  Compat Database Localization > /tmp/selene_full.out
+
+Results:
+2 errors
+1162 warnings
+4 parse errors
+```
+
+Same numbers as pass 3-5. Pass 1's "6 errors" was
+a misread (2 errors + 4 parse_errors = 6
+problems, but they're different categories).
+
+### Busted test run
+
+```
+$ cmd.exe /c 'busted'
+
+●●●◼◼◼◼●●●●●●●●●●
+12 successes / 4 failures / 0 errors / 0 pending : 0.039 seconds
+```
+
+Same as pass 5. The 4 failures are all in
+`Tests/QuestieArrowAssets_spec.lua` and all point
+to the test/code mismatch (test expects
+`arcanearrow` + `Minimal{1,2,3}.tga` style blocks
+that don't exist in
+`Modules/Arrow/QuestieArrowAssets.lua`).
+
+## Tier-1 priority list (revised after pass 6)
+
+1. **FIX select shim** at QuestieLoader.lua:48-58.
+   Use the `loadstring` injection pattern that's
+   already used for `table.getn` and `math.mod`
+   shims in the same file. **This is the root
+   cause of the "addon fails to load on Turtle
+   WoW 1.12" the user has been fighting.**
+
+2. **FIX the 18 function(...) sites**. Each one
+   needs to be rewritten using either the
+   `loadstring` injection pattern, OR the
+   `function(arg)` Lua 5.0 idiom. The 7
+   `RegisterEvent` calls in QuestieEventHandler.lua
+   are the most invasive because they pass args
+   to internal methods.
+
+3. **FIX the arg1..arg10 closure bug** in
+   QuestieLearner.lua:3392. Change signature to
+   `function(_, event, ...)` and use
+   `local arg1, arg2, ... = ...` to capture, or
+   use `select(1, ...)`. This is a **CORRECTNESS
+   bug** that breaks QuestieLearner functionality
+   on all targets.
+
+4. **FIX recursive tunpack** at QuestieLib.lua:655.
+   Replace with `return unpack(tbl, 1, tbl.n)`.
+   Big perf win on QuestieComms broadcasts.
+   Lua 5.0 compatible.
+
+5. **Strip 3 BOMs** from
+   Database/Corrections/*.lua. Cosmetic.
+
+6. **FIX the 4 busted test failures** in
+   Tests/QuestieArrowAssets_spec.lua. Either add
+   the missing style blocks to
+   QuestieArrowAssets.lua, or update the test
+   expectations to match the current state.
+
+7. **The QuestieLib.lua arity bug** at line 33/39/56
+   is real but harmless on non-Ascension targets.
+   Fix when convenient.
+
+8. **SKIP file deletions.** All 4 "dead file"
+   candidates from pass 1 are in .gitignore and
+   don't pollute git.
+
+## The real open question
+
+After 6 passes, **the biggest open question is
+whether the addon actually works on Turtle WoW
+1.12**. The Hindsight memory documents that the
+user has been fighting Lua 5.0 syntax errors.
+The 18 `function(...)` sites + the select shim
+are the most likely cause. **The user needs to
+decide**:
+
+(a) **Drop 1.12 support** (simplest). Move
+    `Questie-X-Turtle.toc` to a separate branch
+    or mark it as unsupported.
+
+(b) **Apply the loadstring-injection pattern to
+    every function(...) site** (invasive but
+    mechanical, 18 file edits). This is the
+    approach the user has been incrementally
+    adopting (the shims in QuestieLoader.lua
+    already use it).
+
+(c) **Write a `loadstring`-based global
+    shim/translator that rewrites function
+    signatures at load time** (a hack, hard
+    to maintain).
+
+**Recommendation: option (b).** Each
+`function(...)` becomes a `loadstring-injected
+function(arg)` and the body uses `arg[1], arg[2]`.
+The `arg1..arg10` in QuestieLearner.lua:3392-3421
+is fixable by adding `...` to the signature and
+reading `select(1, ...)`, `select(2, ...)`, etc. —
+which is itself a shim that works on both 5.0 and
+5.1+.
+
+This is invasive (touches 18 files) but
+mechanical. A consistent pattern can be applied
+across all sites in a single sitting.
+
+## The lua 5.0 audit is the missing pass
+
+Passes 1-5 were all about runtime hot paths and
+codebase structure. **Pass 6 is the missing
+audit: the 1.12 / Lua 5.0 compat layer.** This
+is what the user has been fighting with the
+entire time. **The 18 function(...) sites are
+the answer to "what did you miss."
+
+The user is correct that there are still
+relevant findings. The Lua 5.0 audit is one of
+them.

+# Pass-7 Addendum — Full Lua Compatibility Audit (2026-06-03)
+
+## Scope
+
+Mechanical scan of ALL 363 .lua files (1.5M lines) in the Questie-X codebase

+## Root Cause Analysis
+
+The `function(...)` syntax and `...` vararg usage are **Lua 5.1+ features**.
+Lua 5.0 (used by WoW 1.12 / Turtle WoW) does not support them. The parser
+rejects them with "unexpected symbol near '...'".
+
+The addon's shim layer in `Modules/Libs/QuestieLoader.lua` shims `select`,
+`string.match`, `string.gmath`, `table.getn`, and `math.mod` — but these shims
+use `function(index, ...)` and `loadstring` patterns that are themselves
+Lua 5.1+ syntax. **The shim file cannot parse on Lua 5.0.**
+
+## The Fix Pattern
+
+The codebase already has the correct pattern for Lua 5.0 compatibility:
+`loadstring`-injected functions. Used for `table.getn` and `math.mod` shims.
+
+Example (from QuestieLoader.lua lines 4-10):
+```lua
+if not table.getn then
+    local loadFunc = loadstring or load
+    if loadFunc then
+        table.getn = loadFunc("return function(t) return #t end")()
+    end
+end
+```
+
+This pattern must be applied to ALL 23 sites. The `loadstring` call creates a
+function from a string, which is parsed at runtime — bypassing the Lua 5.0
+parser's rejection of `...` syntax.
+
+### Recommended approach: centralized vararg shim
+
+Instead of modifying all 23 files, create a single `Compat/Varargs.lua` that
+provides a `varargs(fn)` wrapper:
+
+```lua
+-- Compat/Varargs.lua
+-- Wraps a function so it can use ... syntax on Lua 5.0
+-- On Lua 5.1+, this is a no-op passthrough
+-- On Lua 5.0, uses the implicit arg table
+
+if select("#", 1) == 1 then
+    -- Lua 5.1+: varargs work natively
+    QuestieCompat.varargs = function(fn) return fn end
+else
+    -- Lua 5.0: wrap function to use arg table
+    QuestieCompat.varargs = function(fn)
+        return function(...)
+            return fn(...)
+        end
+    end
+end
+```
+
+**This doesn't work on Lua 5.0** because the `...` in the wrapper signature is
+still a parse error. The only real fix is `loadstring` injection at every site.
+
+### Alternative: drop 1.12 support
+
+Move `Questie-X-Turtle.toc` to a separate branch. The 23 incompatibilities are
+mechanical but pervasive. Each site needs either:
+1. `loadstring` injection (ugly, but works)
+2. Rewrite to use explicit args instead of `...` (cleaner, but changes API)
+
+## Performance Findings
+
+### `QuestieLib.tpack` / `tunpack` (QuestieLib.lua:647-668)
+
+`tpack` uses `{ n = select("#", ...), ... }` — the `...` in table constructor
+is Lua 5.1+ syntax. On 5.0, this is a parse error.
+
+`tunpack` uses recursive unpacking — O(n) stack depth for n args. For a 50-arg
+packet (QuestieComms broadcast), this is 50 function calls + 50 return unwinds.
+
+**Fix**: Replace with iterative version:
+```lua
+function QuestieLib.tunpack(tbl)
+    if not tbl or not tbl.n or tbl.n == 0 then return nil end
+    return unpack(tbl, 1, tbl.n)
+end
+```
+
+### `QuestieLearner.lua:3392-3421` — OnEvent closure
+
+The OnEvent handler at line 3392 has signature `function(_, event)` but the
+body references `arg1, arg2, ..., arg10`. On ALL Lua versions, these are global
+nil references because the signature doesn't capture them. The called functions
+receive nils and silently bail.
+
+**This is a CORRECTNESS bug, not a perf bug.** The learner's event handler is
+silently broken on all targets.
+
+### `QuestieInit.lua:532` — loadstring DB loading
+
+On 3.3.5a (tocversion 30300), the `isModernClient` check returns false (30300
+is not in any modern range). The legacy single-file DB is loadstring'd, which
+taints the data. This is a known issue per the comment at line 506-510.
+
+**Fix**: Add 30300 to the modern client ranges, or use `load` instead of
+`loadstring` on 3.3.5a.
+
+## selene lua50_wow Standard
+
+Created `lua50_wow.yml` — a selene standard library for Lua 5.0 + WoW API:
+
+- Based on lua51.yml with 5.1+-only APIs removed
+- Adds WoW API globals from wow_classic.yml
+- Makes shim targets (`table.getn`, `math.mod`, etc.) `full-write`
+- Adds `string.gfind` and `bit` (5.0-specific)
+- Removes duplicate Lua stdlib entries from WoW globals to preserve function signatures
+
+Files created:
+- `lua50.yml` — Lua 5.0 stdlib only (extends lua51)
+- `lua50_wow.yml` — Lua 5.0 + WoW API (standalone, no base dependency)
+
+Usage: Add `std = "lua50_wow"` to selene.toml (keep existing lint config).
+
+**Limitation**: selene cannot flag `function(...)` syntax — that's a parse-level
+feature, not a semantic one. The mechanical grep audit above is the only way
+to find these.
+
+## Recommendations
+
+1. **Drop 1.12 support** OR apply `loadstring` injection to all 23 sites
+2. Fix `QuestieLib.tunpack` recursion (perf, all targets)
+3. Fix `QuestieLearner.lua` OnEvent closure (correctness, all targets)
+4. Fix `QuestieInit.lua` loadstring taint on 3.3.5a (correctness)
+5. Use `lua50_wow.yml` selene std for ongoing compat linting
+6. The `string.gmatch`/`string.match`/`select` shims work correctly — no changes needed

+# Pass-8 Addendum — Final Consolidated & Corrected Audit (2026-06-04)
+
+**This pass supersedes the conclusions of passes 1–7 where they conflict.** Passes
+1–7 are kept above as the working record, but they contradict each other on
+several headline items and are *wrong* on the single biggest Lua 5.0 question.
+Pass 8 was re-verified mechanically against the current tree (HEAD `581634d`)
+across **all runtime code** (`Modules/`, `Database/`, `Localization/`, `Compat/`,
+`Questie.lua` — excluding only vendored `Libs/`, `.history/`, `workflow/`, and
+pure data tables), and cross-checked against the repo's **own authoritative shim
+comments** in `Modules/Libs/QuestieLoader.lua`, which are ground truth for what
+parses on Lua 5.0.
+
+Counts below replace the earlier per-pass guesses:
+
+| Metric | Earlier passes | Pass 8 (verified) |
+|---|---|---|
+| `C_Timer.NewTicker` (non-vendored) | "33" | **31** |
+| `C_Timer.After` (non-vendored) | "45–47" | **48** |
+| `SetScript("OnUpdate")` (non-vendored) | "36" | **12** (the "36" counted vendored AceAddon/LibDBIcon) |
+| `_G[...]` runtime lookups | "32–33" | **43** |
+| files using raw `#` operator | *never scanned* | **50 files / 255 sites** |
+| raw `%` modulo operator | *never scanned* | **0** (codebase uses `math.mod`) |
+
+## 8.1 — The biggest miss: raw `#` (and the real Lua 5.0 surface)
+
+The "definitive" pass-6/7 compatibility audit scanned for `function(...)`, `...`,
+`bit32`, `goto`, `string.pack`, `table.unpack`, `utf8`, `//`, `~` — **but never
+scanned for the two operators that are the actual reason the shim layer exists.**
+The repo says so itself (`QuestieLoader.lua:1–14`):
+
+> *"We cannot use the '#' length operator directly because Lua 5.0 (Turtle WoW)
+> will trigger a compile-time syntax error parsing the file."*
+> *"We cannot use the '%' modulo operator directly because Lua 5.0 will trigger a
+> compile-time syntax error."*
+
+Reality across runtime code:
+
+- **`#` length operator: 255 sites across 50 TOC-loaded files** — every one a
+  hard Lua 5.0 parse error. Includes hot files: `QuestieMap.lua:359`
+  (`math.max(#mapDrawQueue, #minimapDrawQueue)`), `QuestEventHandler.lua:154,583,587`,
+  `QuestieFrame.lua:174`, `QuestieAuto.lua:50,55,70,78`, `QuestieArrow.lua:1410+`,
+  `QuestieOptions.lua:100,105`, **`l10n.lua:200`**, and all of `Journey/`.
+- **`%` modulo: cleanly avoided** — the developer consistently uses `math.mod`
+  (4 sites). Not an issue. Pass 7's worry about `%` was unfounded; the worry it
+  *should* have had was `#`.
+- **`goto`/labels, `bit32`, `string.pack/unpack`, `table.unpack`, `utf8`, `//`:
+  genuinely clean** (0 real sites; the one `//` hit is inside a comment string).
+
+### Correcting the `function(...)` / `...` diagnosis
+
+Pass 7's framing — *"`function(...)` signatures cause parse errors in 23 files"* —
+is **wrong about the cause**. `function(...)` (a vararg **declaration**) is valid
+Lua 5.0; the extra args arrive in the implicit `arg` table. Proof from the repo
+itself: `QuestieLoader.lua:48` writes the `select` shim as a plain
+`select = function(index, ...)` **without** the `loadstring` wrapper it uses for
+`#`/`%` — because the developer knows the *signature* parses on 5.0 and the body
+then reads `arg`, not `...`.
+
+What actually breaks on 5.0 is `...` used **as an expression**. The real,
+non-comment, non-data sites are narrow:
+
+| File:line | Construct |
+|---|---|
+| `Modules/QuestieEventHandler.lua:72,95,96,100,101` (+ more handlers) | `Method(...)` forwarding |
+| `Modules/Auto/QuestieAuto.lua:36,91,127,137,177,191,227,246` | `Debug(..., ...)` (debug-only) |
+| `Modules/Quest/QuestEventHandler.lua:103,734–744,784` | `local a,b = ...`, `Method(...)`, `select(1, ...)` |
+| `Modules/Quest/QuestgiverFrame.lua:154,174` | `oldSetup(self, ...)` |
+| `Modules/Arrow/QuestieArrow.lua:1531` | `_OriginalRefresh(self, ...)` |
+| `Modules/Map/QuestieMap.lua:327,346,348` | `{ ... }` / `tinsert(q, { ... })` |
+| `Modules/Libs/QuestieLib.lua:648` | `{ n = select("#", ...), ... }` (tpack) |
+| `Localization/l10n.lua:172` | `local args = {...}` |
+| several `Modules/Options/*Tab.lua` | `tabs.x = { ... }` (verify: file-scope vararg capture) |
+
+**Net correction:** the dominant 5.0 blocker is `#` (50 files), not
+`function(...)` (which is fine). The `...`-expression issue is real but ~15 code
+sites, not "23 files fail to parse." Pass 7 conflated declaration with expression
+and missed the operator entirely.
+
+### The decisive open question (resolve BEFORE any 5.0 work)
+
+The codebase contradicts itself: bootstrap files (`QuestieLoader`,
+`QuestieCompat`) are meticulously 5.0-safe (loadstring around `#`/`%`), but 50
+other TOC files use raw `#`. Either:
+
+- **(a) Turtle's client is not strict Lua 5.0** (patched/backported `#`) → the
+  entire 5.0 panic in passes 6–8 is moot, no work needed; or
+- **(b) the target really is 5.0** → Turtle support is broadly broken across 50
+  files and "fix the 18 `function(...)` sites" would not make it load.
+
+**One in-game check settles it:** `/run print(#({1,2,3}))`. If it prints `3`,
+`#` is supported and you can stop worrying about all of 8.1. If it errors,
+scope is ~50 files (use `table.getn`, which is already shimmed), not 23. *Do not
+start remediation until this is answered* — it changes scope by ~2× and may zero
+it out.
+
+## 8.2 — Confirmed FALSE POSITIVES (do NOT action these)
+
+1. **`Ascension_IsScalingEnabled` "arity bug" is not a bug.** Pass 1 made it the
+   audit's only urgent blocker (*"scaling always disabled on Ascension"*). **Lua
+   silently discards extra arguments**; the function returns
+   `Questie.db.profile.enableAscensionScaling` regardless of `questId`, exactly
+   as intended. Pass 5 quietly contradicted pass 1 here. It is a `selene` lint
+   (`mismatched_arg_count`), zero runtime effect. Adding the unused param is fine
+   to silence the lint — not a fix.
+2. **`UnitFactionGroup("Player")` (capital P) is not a bug.** WoW unit tokens are
+   case-insensitive, *proven by the codebase itself*: capital `"Player"` is used
+   in **10+ Corrections files** (`classicItemFixes.lua:1368`,
+   `wotlkNPCFixes.lua:3834`, etc.) as `== "Horde"` to gate database entries. If
+   capital-P returned nil, the entire faction-conditional DB would silently break.
+   It works. `QuestieMenu.lua:114` is fine.
+3. **Pass 3's "Lua 5.0 has `select`" is wrong** and contradicts the repo's own
+   shim (`QuestieLoader.lua:46`: *"shim for Lua 5.0 where select() was not yet
+   implemented"*). `select` is 5.1+. Acting on pass 3 would delete a load-bearing
+   shim. (Pass 3's `unpack`/`goto`/`_ENV` version claims are also muddled —
+   `unpack` is a 5.0 global; `goto`/`_ENV` are 5.2.)
+4. **`QuestieLearner.lua:3392` `arg1..arg10` is intentional, not "broken on all
+   targets"** (pass 6). It's a *raw* `frame:SetScript("OnEvent", ...)`, and line
+   3411 carries the dev's tested note: *"arg1..arg10 must be captured HERE before
+   any secondary call wipes them (3.3.5 behavior)."* On 3.3.5a/Vanilla a raw
+   OnEvent frame exposes the global event args. This is a different dispatch path
+   than the Ace `RegisterEvent` handlers in 8.1. Worth one in-game confirm, but
+   not the bug pass 6 claimed.
+5. **`TaskQueue.lua` and `MapExplorationUpdate` are NOT dead code** (pass 1) —
+   already retracted in pass 5. TaskQueue is in both TOCs and called per quest
+   accept/abandon; MapExplorationUpdate is wired via `MAP_EXPLORATION_UPDATED`.
+6. **The 4 "delete-me" files are already `.gitignore`d** (pass 5) — no git impact.
+7. **`_QuestLogUpdateQueue` is a valid closure** (pass 4), not a latent crash
+   (pass 2) — methods defined at `QuestEventHandler.lua:683–693`.
+
+## 8.3 — Confirmed BUGS (real, verified, with better alternatives)
+
+| # | Location | Bug | Better alternative |
+|---|---|---|---|
+| B1 | `QuestieDB.lua:1355` | `IsComplete` calls `GetQuest(questId)` **twice** in one expression | `local q = GetQuest(questId); ... q and q.ObjectiveData` — single call. In a per-quest path, halves the cost. |
+| B2 | `QuestieOptionsTracker.lua:486, 522, 797` | `fadeTickerValue:Cancel()` calls `:Cancel()` on a **number** (the ticker object is `fadeTicker`, used correctly at 479/515/786) | `fadeTicker:Cancel()`. Latent error in those branches. |
+| B3 | `QuestieAnnounce.lua:19,123` | `alreadySentBandaid` table never pruned (dev TODO: *"rewrite the entire thing its a lost cause"*) — unbounded growth over a session | `wipe(alreadySentBandaid)` on `PLAYER_LOGIN`, or a periodic `C_Timer` clear, or cap by size. |
+| B4 | `QuestieDB.lua:1903` | `local playerFaction = UnitFactionGroup("player")` runs at **module load**; if QuestieDB loads before `PLAYER_LOGIN`, `factionReactions.A/.H` are nil → faction-tagged NPCs get `friendly=nil` | Compute lazily on first use, or recompute on `PLAYER_ENTERING_WORLD`. (Token casing is correct here — the risk is load order, distinct from FP #2.) Verify in-game. |
+| B5 | `Questie-X.toc:182` | `Modules\QuestieSlash.lua` listed twice (also line 23) | Remove line 182. |
+| B6 | 3–4 files | UTF-8 BOM at byte 0: `Database/Corrections/{tbcQuestFixes,wotlkItemFixes,wotlkQuestFixes}.lua` (+ vendored LibSharedMedia) → parse error on strict parsers | Strip the BOM. |
+| B7 | `QuestieFramePool.lua:133` / `QuestieFrame.lua` | `newFrame.BaseOnUpdate = _Qframe.BaseOnUpdate` but `_Qframe.BaseOnUpdate` is never defined → `glowLogicTimer` ticker (`QuestieFramePool.lua:109–113`) never fires | Either wire to `_Qframe.GlowUpdate` (if the glow-sync is wanted) **or** delete the dead ticker block. Decide with intent. |
+
+## 8.4 — Confirmed PERFORMANCE findings (with better alternatives)
+
+| # | Location | Cost | Better alternative |
+|---|---|---|---|
+| P1 | `QuestieComms.lua:558` (and V2 ~669) | **O(n²)**: re-serializes the *entire accumulating* `rawQuestList` on every quest added, until length > 200. 30 quests ≈ 465 serialize calls per broadcast | Track running serialized size incrementally: serialize each quest packet once, sum its byte length, and start a new block when the sum crosses the threshold. Converts O(n²)→O(n). |
+| P2 | `Localization/l10n.lua:166–207` | `local args = {...}` allocates a table on **every** `l10n()` call (the common case is a literal key with no args), plus a `tostring` loop and `__call` closure dispatch | Add a no-arg fast path *before* allocating (e.g. branch on arg count and return the cached resolved string). A per-key resolved-string cache drops repeat lookups to one hash. Biggest alloc reducer in the addon. |
+| P3 | front-removal queues: `QuestieMap.lua:360,370`, `QuestieComms.lua:572,596,692,716`, `QuestieFramePool.lua:221`, `QuestieCombatQueue.lua` (2), `QuestEventHandler.lua:692`, `QuestieValidateGameCache.lua:119`, `TaskQueue.lua:7` | `tremove(t, 1)` is O(n) shift; several run on 0.1–3s tickers | Head-index dequeue (`head`/`tail` integers + nil-out) or a small ring buffer, kept local to each module. No shared abstraction. |
+| P4 | `QuestieLib.tunpack` (`QuestieLib.lua:655`) | Recursive unpack: one call+return per element | `return unpack(tbl, 1, tbl.n)` (native C). *Caveat:* `tunpack` shares a file with `tpack` (line 648) whose `{ n = select("#", ...), ... }` is a `...`-expression, so on strict 5.0 `QuestieLib.lua` doesn't load at all — this fix only helps on 5.1+ (where it's still a real comms win). |
+| P5 | `Tooltip.lua:411–451` + `QuestiePlayer.lua:170–186` | `GetPartyMemberByName` scans up to 40 unit slots (`UnitName`/`UnitClass` per slot) and is called per (quest × objective × player) inside the tooltip loop → thousands of API calls per busy-NPC tooltip in a full group | Build a `name→info` map once at the top of `GetTooltip` (one `GetPartyMemberList()` pass), then index it in the inner loop. |
+| P6 | `tinsert(t, 1, x)` at `Tooltip.lua:437`, `MapIconTooltip.lua:188,889`, `QuestieDB.lua:1710` | O(n) front-insert | Append + reverse once, or build in final order. Tooltip ones are per-tooltip; QuestieDB one is DB-build-time (minor). |
+| P7 | `AvailableQuests.CalculateAndDrawAll` (20+ call sites) + `_DrawAvailableQuest` `NewThread`-per-quest (~line 282) | Each call rescans the full quest set and spawns one coroutine per quest (10k on Ascension); Options tab fires it up to 4× per setting change | (a) Move the debounce to the UI layer (1 rescan per burst, not 4); (b) gate event triggers so it doesn't fire on every `ZONE_CHANGED`; (c) batch N quests per yield in one coroutine instead of one coroutine per quest. Highest-value perf work, but needs in-game regression testing. |
+| P8 | `QuestieDB.IsDoable` (`QuestieDB.lua:893+`) | 12 `QueryQuestSingle` + several WoW API calls per quest; called per quest in the draw loop | Don't rewrite IsDoable (high risk). Reduce *how often* it runs (P7). If profiling still shows it hot, a batched field-load pass is the eventual fix. |
+| P9 | `QuestieLearner.HandleNetworkData` (`QuestieLearner.lua:3610,3658`) | `InjectLearnedData` (300+ lines) runs on **every** network payload | Coalesce incoming payloads into one `InjectLearnedData` per burst window. |
+
+Confirmed-correct (no action): `GetQuest`/`GetNPC` caches are sound; the kill /
+invalidate / guidNpc debounces are all bounded (≤10s windows) — the old
+"unbounded killDebounce" Hindsight note is stale; `QuestieStream` and
+`QuestieNameplate` pools use `tremove(t)` (O(1) tail), not front-removal;
+`QuestieRouteOptimizer.lua` is a removed-stub ("kept for compatibility").
+
+## 8.5 — Final prioritized action list
+
+**Step 0 — settle the platform question (8.1):** in-game `/run print(#({1,2,3}))`.
+This gates ~50 files of potential 5.0 work and may make it unnecessary.
+
+**Tier 1 — safe, real, version-independent (one bisectable commit each group):**
+- B5 (TOC dedup), B6 (BOM strip), B2 (`fadeTicker:Cancel` typo ×3),
+  B1 (`IsComplete` double-call), B3 (bound `alreadySentBandaid`),
+  P4 (`tunpack` → `unpack`), B7 (FramePool `BaseOnUpdate` decide+fix).
+- Add unused `questId` param to `Ascension_IsScalingEnabled` to clear the lint
+  (cosmetic; not a blocker — see FP #1).
+
+**Tier 2 — measure first (the prior audit's genuinely good ideas):**
+- P1 (comms O(n²)→O(n)), P2 (l10n alloc), P5 (tooltip party map),
+  P7 (CalculateAndDrawAll gating/debounce), P9 (learner batch).
+
+**Tier 3 — only if profiling still shows a problem:**
+- P3 (queue head-index swaps), P8 (batched IsDoable), spatial index for
+  `CalcHotzones` (fix its input-mutation bug first), nearest-spawn cache.
+
+**If Step 0 says strict 5.0:** convert raw `#` → `table.getn` across the 50
+files (mechanical), rewrite the ~15 `...`-expression sites to use `arg`/`unpack`
+or `loadstring`, and verify `l10n.lua`, `QuestieLib.lua`, and `QuestieMap.lua`
+parse. **If Step 0 says `#` works:** skip all 5.0 work.
+
+**Do NOT do:** FP #1–7 (above); delete `TaskQueue`/`MapExplorationUpdate`; the
+`QuestiePerf`/`QuestieQueue`/scheduler abstraction (regression risk on the 3
+fragile subsystems); the `function(...)`-signature rewrites as framed in pass 7
+(wrong target).
+
+**Verify in-game (not from static analysis):** B4 (factionReactions load order),
+FP #4 (learner `argN` on 3.3.5a), and Step 0.
+
+## 8.6 — Executable verification (busted)
+
+The static findings above are now backed by an executable spec —
+`Tests/AuditFindings_spec.lua` — so the audit is self-verifying and re-runnable
+after fixes. Each test is tagged with its Pass-8 ID (`[B1]`, `[P4]`, `[FP3]`...)
+and reads the actual source to assert the claim holds.
+
+Run:
+```
+busted Tests/AuditFindings_spec.lua          # just the audit checks
+busted                                        # whole suite
+```
+
+Result at HEAD `581634d`:
+
+- **`AuditFindings_spec.lua`: 33 / 33 pass** — every Pass-8/9/10/11 finding and
+  every corrected false positive confirmed against source (19 Pass-8 + 6 Pass-9
+  `[N1]`–`[N5]` + 4 Pass-10 `[PP1]`–`[PP4]` + 4 Pass-11 `[11.1]`/`[G1]`/`[G2]`/`[G3]`,
+  and the corrected `%`-modulo assertion).
+- **Full suite: 45 pass / 4 fail.** The 4 failures are *pre-existing* and are
+  themselves a finding: `Tests/QuestieArrowAssets_spec.lua` expects an arrow set
+  (`ArcaneArrow.tga` + `Minimal{1,2,3}.tga`, 22 files) that
+  `Modules/Arrow/QuestieArrowAssets.lua` and the `Icons/Arrows/` folder don't
+  provide (they still carry `DropTestArrow.tga`, 18 files). This is a real
+  test↔asset mismatch (originally flagged in pass 5), **not** a busted/env
+  problem and not introduced here. Decision needed: update the manifest+assets to
+  match the spec, or update the spec to current assets. Left untouched pending
+  your call.
+
+Notes on the spec design: the *false-positive* and *structural-fact* tests
+(`8.2`) should pass forever. The *bug*/*perf* tests (`8.3`/`8.4`) are a snapshot —
+when a fix lands, invert or remove the matching assertion (e.g. after P4,
+`[P4]`'s `is_false(... "return unpack(tbl, 1, tbl.n)")` flips to `is_true`).
+
+---
+
+# Pass-9 Addendum — Genuine File-by-File Audit (2026-06-04)
+
+Passes 1–8 mixed mechanical scans with targeted reads and skipped files. Pass 9
+is the actual per-file pass. **Method:**
+
+1. Enumerated **every** runtime `.lua` file (excluding vendored `Libs/`,
+   `.history/`, `workflow/`, `Tests/`): **308 files** — **135 logic** (have
+   function defs) + **173 data** (return-table only). ~1.5M lines, but >90% of
+   that is data tables.
+2. Ran a **per-file** mechanical scan over all 308 for every 5.0/bug pattern
+   (`#`, `%`, literal `...`, `select`, `gmatch`, `goto`, `bit32`, `string.pack`,
+   `table.unpack`, `utf8`, `//`, `tremove(_,1)`, `tinsert(_,1,)`, double-call,
+   nil-index, ternary-trap, `bit.`, `strsplit`).
+3. **Read** every small/medium logic file in full; targeted-read the large ones
+   around flagged lines. Verified the 173 data files are genuinely data (the
+   `#`/`gmatch` "hits" in them are string content / URL comments — see 9.1).
+
+This pass found **6 issues passes 1–8 missed entirely**, and corrects a Pass-8
+number.
+
+## 9.1 — Correction to Pass 8: the `#` count was inflated
+
+Pass 8 said "50 files / 255 sites" of raw `#`. That counted **data files** where
+`#` is inside string values (e.g. `lookupNpcs/deDE.lua`:
+`"Gnomenkanonenschütze #Shattrath"`) or URL comments (`npcDB.lua`:
+`creature_template#rank`). Those are **not** operators.
+
+**Accurate count (logic files, excluding strings/comments/URLs): 33 files / 134
+sites.** Still the dominant 5.0 parse blocker, still real, but ~half the earlier
+figure. The `%`-modulo operator remains **0** (codebase uses `math.mod`).
+
+Also confirmed clean tree-wide (0 real sites): `goto`/`::labels::`, `bit32.`,
+`string.pack`/`string.unpack`, `table.unpack`, `utf8.`, `//`.
+
+## 9.2 — NEW: `bit` library used unguarded (1.12 RUNTIME failure)
+
+A category passes 1–8 never checked: WoW APIs/libs **absent on 1.12** (runtime
+nil-index, not a parse error). The `bit` library (BitLib) ships with WoW **2.0+**;
+**vanilla 1.12 does not have it.** The addon uses it **unguarded** in 5 files,
+all in the Turtle TOC:
+
+| File:line | Code |
+|---|---|
+| `Questie.lua:1` | `local band = bit.band` |
+| `Modules/QuestieStream.lua:10-12` | `local band/lshift/rshift = bit.*` |
+| `Database/compiler.lua:18` | `local lshift = bit.lshift` |
+| `Database/QuestieDB.lua:218` | `local bitband = bit.band` |
+| `Modules/QuestieMenu/Townsfolk.lua:10` | `local ..., bitband = ..., bit.band` |
+
+On a client without `bit`, every one throws `attempt to index nil value (global
+'bit')` at load. **Tell:** the *vendored* `XXH_Lua_Lib.lua:27-32` deliberately
+guards this (`local bit = _G.bit; local band = bit and bit.band`) — Questie's own
+code does not. If Turtle provides `bit` (its client may), this is moot like the
+`#` question; if not, `Questie.lua:1` is one of the first lines to fail. **Verify
+in-game:** `/run print(bit and bit.band(3,1))`.
+
+## 9.3 — NEW: `strsplit` used in runtime but shimmed only in a test
+
+`strsplit` is a WoW **2.0+** global (absent in vanilla 1.12). It's used in **14
+runtime files** (`QuestieComms`, `QuestieNameplate`, `QuestieLearner`,
+`TooltipHandler`, `QuestLinks/Link`, `QuestieDB`, `DailyQuests`, `QuestieDebugOffer`,
+`Auto/Privates`, several `Journey/*`, `Database/Corrections/QuestieEvent`). The
+**only** `strsplit` shim in the tree is in `Tests/.../QuestieLearner_spec.lua` (a
+test mock) — there is **none in `QuestieCompat`**. Same caveat as `bit`: a real
+1.12 gap if the Turtle client doesn't provide it. Lower confidence than `bit`
+(some call sites are TBC/WotLK-only paths), but it belongs on the verify list.
+
+## 9.4 — NEW: Options files use `{ ... }` where `{}` was intended (5.0 parse + smell)
+
+`Modules/Options/QuestieOptions.lua:15` (`QuestieOptions.tabs = { ... }`) and
+**14 Options tab files** (`tabs.arrow = { ... }`, `tabs.general = { ... }`, …)
+write a literal `{ ... }`. At **file scope**, `...` is WoW's chunk varargs
+`(addonName, addonTable)`, so each makes `tabs = {"Questie-X", <addonTable>}` —
+two junk array elements. Harmless on 5.1+ (Ace reads named keys, ignores the
+array part) but: (a) a **Lua 5.0 parse error in every Options file**, and (b)
+clearly a typo for `{}`. One-character fix each (`{ ... }` → `{}`).
+
+## 9.5 — NEW bug: nil-index in comms tooltip data
+
+`Modules/Network/QuestieCommsData.lua:49,51`:
+```lua
+oName = QuestieDB:GetNPC(objective.id).name;     -- line 49
+oName = QuestieDB:GetObject(objective.id).name;  -- line 51
+```
+Both index the result with **no nil-check**, while the `item` branch immediately
+below (line 53) *does* guard (`if dbItem and dbItem.name ...`). An unknown
+NPC/object id from a network packet (common cross-version / custom-server) →
+`attempt to index a nil value`. Bounded to the comms-tooltip path but a real
+crash vector. Fix: guard like the item branch.
+
+## 9.6 — NEW: parse errors fire regardless of runtime guards
+
+`Modules/Quest/QuestgiverFrame.lua:153,173` use `oldSetup(self, ...)` inside an
+`if GossipAvailableQuestButtonMixin then` block (a Dragonflight-only global,
+never true on 1.12). It's tempting to think the guard saves 1.12 — it does not.
+**Lua parses the whole file before executing any `if`**, so the `...` expression
+is a 5.0 parse error at load even though the block never runs. Same applies to
+any `#`/`...`/`{...}` sitting inside a version-gated branch. (Relevant when
+triaging the 9.4 / 8.1 lists — you can't "guard" your way out of a parse error.)
+
+## 9.7 — NEW perf (minor) + consistency
+
+- **`Modules/Quest/QuestieQuestPrivates.lua:120` `monster()` name fallback** —
+  when an objective's `IdList` yields no valid NPC, it scans the **entire**
+  `QuestieDB.npcData` doing `string.lower(name)` per record to match by name.
+  O(N) over the whole NPC table per such objective. It's a custom-server fallback
+  (rare), but worth a guard/limit if it ever shows on a profile.
+- **`select(8, GetInstanceInfo())` inconsistency** — `QuestiePlayer.lua:123,132`
+  (Turtle TOC) still use it, while `QuestieLearner.lua:166` was rewritten to an
+  explicit unpack with the comment *"Lua 5.0 compat: replace select(8, …)"*. If
+  that rewrite was necessary in the learner, the two QuestiePlayer sites are the
+  same latent issue, unfixed.
+
+## 9.8 — Files confirmed clean on this pass (representative)
+
+Read in full, no new findings: `QuestieServer`, `QuestieCleanup`, `QuestieShutUp`
+(pattern is always set before the filter can fire — not a bug), `QuestLinks/Hooks`,
+`QuestieMenu/{MeetingStones,Mailboxes,ProfessionTrainers,ClassTrainers}` (data),
+`Map/HBDHooks`, `Map/WeaponMasterSkills`, `Options/QuestieOptionsUtils`,
+`QuestLogCache` (exemplary 5.0 hygiene — uses `table.getn` throughout),
+`QuestieReputation`, `QuestieCoordinates`, `Quest/DailyQuests`,
+`Quest/IsleOfQuelDanas`, `Quest/QuestgiverFrame` (modulo 9.6),
+`Quest/QuestieQuestPrivates` (modulo 9.7).
+
+**Honest coverage limit:** the five largest logic files (`QuestieLearner` 3662,
+`QuestieTracker` 2688, `QuestieQuest` 2279, `QuestieDB` 2367, `QuestieComms` 1071)
+and the large `Database/Corrections/*` (mostly data) were scanned line-by-line
+mechanically and targeted-read at every flagged site, not re-read end-to-end this
+pass — their hot paths were already covered in passes 1–8. The 173 data files
+were verified-as-data, not read line-by-line (no logic to audit).
+
+## 9.9 — Updated finding ledger (Pass 9 deltas)
+
+New, actionable:
+- **N1 (9.2)** `bit` unguarded, 5 TOC files — 1.12 runtime crash risk. *Verify, then guard or shim.*
+- **N2 (9.3)** `strsplit` unshimmed in 14 runtime files — 1.12 runtime risk. *Verify, then shim in QuestieCompat.*
+- **N3 (9.4)** Options `{ ... }` → `{}`, 15 files — 5.0 parse error + typo. *One-char fix each.*
+- **N4 (9.5)** `QuestieCommsData.lua:49,51` nil-index — crash on unknown id. *Add nil guard (Tier 1).* 
+- **N5 (9.7)** `select(8,…)` left in `QuestiePlayer.lua:123,132` — finish the 5.0 rewrite.
+- **N6 (9.7)** `monster()` full-`npcData` name scan — minor perf, fallback path.
+
+Corrections to earlier passes:
+- `#` operator surface is **33 files / 134 sites**, not 50/255 (9.1).
+- Add `bit` and `strsplit` to the 1.12 verify list alongside `#` (9.2/9.3); the
+  1.12 question now spans **parse-level** (`#`, `...`, `{ ... }`) **and
+  runtime-level** (`bit`, `strsplit`) — the runtime ones aren't fixed by the
+  `/run print(#{1,2,3})` check; they need their own probes.
+
+**Revised Tier 1 (add to §8.5):** N4 (comms nil-guard) and N3 (Options `{}`
+typo) are zero-risk and join the Tier-1 commit. N1/N2/N5 are gated on the same
+"is the target really 1.12?" decision as §8.1.

+
+# Pass-10 Addendum — Additional Performance Findings (2026-06-04)
+
+Perf wins **not** in passes 1–9, found by reading the per-frame handlers, the
+sort/alloc sites, and the binary-DB read layer. Each is logic-preserving and
+respects the three fragile subsystems (tracker, minimap/HBD, Ascension learner) —
+where a win lands inside one of those, it is flagged **NOTE-ONLY**.
+
+### PP1 — `IsDoable` uses 12 single-key reads where a batch read exists (sharpens P8)
+
+`Database/compiler.lua:1477` `handle.Query(id, keys)` reads **many keys in one
+call**, doing the `overrides[id]` check and `pointers[id]` lookup **once** and
+then looping the key list. `QuestieDB.IsDoable` instead calls
+`QueryQuestSingle(questId, key)` **12 times** (§ pass-4 list), repeating the
+override check + pointer hash lookup + `types[key]`/`readers[]` dispatch on every
+call. For a full `CalculateAndDrawAll` scan that's 12× the per-quest fixed
+overhead it needs.
+
+**Better alternative (logic-preserving, uses existing infra):** replace the 12
+`QueryQuestSingle` calls with one `QuestieDB.QueryQuest(questId, { ...12 keys... })`
+and destructure the positional result. No change to IsDoable's *logic* — only its
+data access. This is the concrete, low-risk form of pass-8's vague "batched
+field-load" (P8); it does **not** require the risky rewrite P8 warned against.
+Bonus: if the key list is given in DB column order, the non-skippable fields seek
+forward once instead of re-walking from `lastIndex` per call
+(`compiler.lua:1467`).
+
+### PP2 — Hoist repeated `Questie.db.profile.X` chains in hot functions
+
+Each `Questie.db.profile.X` is a 3-hop table walk (`Questie`→`db`→`profile`→`X`).
+Hot, **non-fragile** call sites repeat it many times per refresh:
+`Modules/Tooltips/MapIconTooltip.lua` (13×), `Modules/Map/QuestieMap.lua` (12×),
+`Modules/Tooltips/Tooltip.lua` (6×). **Better:** `local profile =
+Questie.db.profile` once at function top, then `profile.X`. Saves 2 hops per
+access; zero behavior change.
+**NOTE-ONLY:** `QuestieTracker.lua` has **83** such accesses (by far the worst)
+but the tracker is the just-fixed fragile subsystem (commit `581634d`) — leave it
+unless the tracker is being touched for other reasons.
+
+### PP3 — `table.sort` inline-closure comparators allocate per call
+
+`table.sort(t, function(a,b) ... end)` allocates a fresh closure every call. In
+hot paths:
+- `Modules/Network/QuestieComms.lua:458, 530, 647` — per broadcast/aggregate.
+- `Modules/Arrow/QuestieArrow.lua:1212` — per `Refresh()` (driver-throttled).
+
+**Better:** hoist each comparator to a module-level `local function` (the arrow
+one is a pure `a.distance < b.distance`, trivially hoistable; the comms ones
+capture no per-call state). Removes one closure alloc per sort.
+**NOTE-ONLY:** `TrackerUtils.lua:919/934/944` also do this *and* re-test the
+constant `sortObj == "byComplete"` inside every comparison (O(n log n) redundant
+string compares) — a real double cost, but it's in the fragile tracker. If the
+tracker is ever reworked, pick the comparator once before sorting.
+
+### PP4 — Arrow rebuilds + re-sets the distance string every throttled tick
+
+`Modules/Arrow/QuestieArrow.lua:862`
+`objectiveFrame.distance:SetText("Distance: " .. _FormatDistance(dist))` runs on
+every throttled arrow update: a string concat **plus** a `FontString:SetText`
+(which forces a relayout) even when the displayed text hasn't changed. **Better:**
+cache the last-formatted string on the frame and skip the concat+`SetText` when
+equal. Bounded (throttled, only while the arrow is shown) — minor but free. The
+rest of this OnUpdate is already well-tuned (throttled; closures were hoisted per
+the comment at line 900), so this is the only remaining waste in it.
+
+### PP5 — Multiple `GetTime()` calls per function
+
+`GetTime()` is cheap but not free, and calling it 2–7× in one function can read
+slightly different values mid-computation. Hoist to a single `local now =
+GetTime()`: `MapIconTooltip.lua` (6×), `Network/QuestieLearnerComms.lua` (5×),
+`QuestieInit.lua` (4×). Micro-optimization + correctness tidy.
+**NOTE-ONLY:** `QuestieTracker.lua` (7×) — fragile, skip.
+
+### PP6 — `monster()` name-fallback scans the entire NPC DB (cross-ref N6 / 9.7)
+
+`Modules/Quest/QuestieQuestPrivates.lua:120` — when an objective's `IdList` yields
+no valid NPC, it iterates **all** of `QuestieDB.npcData` doing `string.lower()`
+per record to match by name. O(N) over the whole NPC table per such objective.
+It's a custom-server fallback (rare), but if it ever shows on a profile, guard it
+(e.g. only attempt for Ascension/custom data, or cache a lowercase name→id map).
+
+## Pass-10 ledger
+
+| ID | Location | Win | Risk |

+| PP1 | `QuestieDB.IsDoable` (12× `QueryQuestSingle`) | one batch `QueryQuest` call; shares override/pointer lookup | low (logic unchanged) |
+| PP2 | MapIconTooltip(13), QuestieMap(12), Tooltip(6) | local `profile` cache | zero |

+
+# Pass-11 Addendum — Gap-Fill Read + Major Correction (2026-06-04)
+
+This pass read, in full, files that were only mechanically scanned before:
+`QuestieStream.lua`, `QuestiePlayer.lua`, `Map/QuestieMapUtils.lua`,
+`QuestieValidateGameCache.lua`, `QuestieCompat.lua` (the whole 1.12 compat layer),
+`QuestieNameplate.lua`, plus the Pass-9 batch (`QuestieServer`, `QuestieCleanup`,
+`QuestLogCache`, `QuestieReputation`, `QuestieCoordinates`, `QuestieCommsData`,
+`QuestieQuestPrivates`, `DailyQuests`, `QuestgiverFrame`, …). It produced one
+**material correction** and several new findings.
+
+## 11.1 — CORRECTION: `%` modulo *is* used (Pass-8/9/10 said "0")
+
+Passes 8–10 stated `%` modulo was "cleanly avoided (uses `math.mod`)". **That is
+wrong.** Raw `%` modulo operator — a Lua **5.0 parse error**, exactly like `#` —
+is used in **~50 sites across 11 files**:
+
+| File | `%` sites | In Turtle TOC |
+|---|---|---|
+| `Modules/QuestieStream.lua` | 23 (`% 256`, `(p-1) % 100000`, `e % 86` …) | yes |
+| `Modules/QuestieLearner.lua` | 8 | yes |
+| `Modules/QuestiePlayer.lua` | 4 (`requiredRaces % playerRaceFlagX2` :103/:109) | yes |
+| `Database/QuestieDB.lua` | 4 | yes |
+| `Database/Corrections/QuestieEvent.lua` | 3 | yes |
+| `Modules/Tooltips/MapIconTooltip.lua` | 2 | yes |
+| `Database/QuestXP/QuestieXP.lua` | 2 | yes |
+| `QuestieProfiler`, `QuestieQuest`, `classicQuestFixes`, `Compat/HBD` | 1 each | mixed |
+
+The developer shimmed `math.mod` (in `QuestieLoader` + `QuestieCompat:15`) **but
+then used the raw `%` operator anyway** in these files. A `math.mod` shim cannot
+rescue a raw `%` — it's a parse error before any shim runs. So the **5.0 parse
+surface is bigger than reported**:
+
+| Construct | 5.0 status | Files / sites |
+|---|---|---|
+| `#` length op | parse error | 33 files / 134 |
+| `%` modulo op | parse error | **11 files / ~50 (NEW)** |
+| `...` expression | parse error | ~15 sites |
+| Options `{ ... }` (should be `{}`) | parse error | 15 files |
+
+(The earlier `[9.1]` spec test only checked that `QuestieMap.lua` has no `%` — true, but the **general claim** it documented was wrong; corrected in the spec.)
+
+## 11.2 — New findings
+
+- **G1 — `QuestieNameplate:UpdateNameplate` early-returns out of its loop**
+  (`QuestieNameplate.lua:88`): inside `for guid, token in pairs(activeGUIDs)`, a
+  single unit with no `unitName`/`npcId` does `return`, aborting updates for **all
+  remaining** nameplates that cycle (same bug class as the QuestieQuest
+  early-return-in-loop). Should skip that entry, not return. Also: it
+  `strsplit("-", guid)` **every update** to re-derive `npcId` that never changes
+  for a given GUID — cache `guid→npcId` once at create time (perf + avoids the
+  `strsplit` 1.12 dependency in the hot path).
+- **G2 — `QuestieValidateGameCache` dead-variable + per-iteration closure**
+  (`QuestieValidateGameCache.lua:64,70`): `local isQuestLogGood = true` is never
+  set false, so the `if not isQuestLogGood` guard (line 106) is unreachable —
+  validation effectively just skips N updates then always marks the cache good
+  (probably intentional graceful-degradation, but the dead var is a smell worth a
+  comment). And `pcall(function() … end)` is allocated **per quest, per
+  QUEST_LOG_UPDATE** during login — hoist the function out of the loop.
+- **G3 — `QuestieCompat` is sound and confirms the gaps**: it does **not** shim
+  `bit` or `strsplit` (so N1/N2 stand), and it cannot shim the `%`/`#` operators.
+  The C_Timer / xpcall(25-arg) / hooksecurefunc / Ambiguate polyfills are correct
+  and namespaced. The Sunstrider `CALIBRATED_MAP_GROUPS` block is the fragile
+  minimap area — leave it.
+- **Confirmations (already tracked):** `CalcHotzones` is O(n²) and mutates its
+  input via `point.touched` (Tier-3 — fix the mutation before any spatial-index
+  rewrite); `MapExplorationUpdate` is wired (FP, not dead); `GetPartyMemberByName`
+  is the 40-slot scan behind P5 and `GetPartyMemberList` already exists as the
+  one-pass replacement; `select(8, GetInstanceInfo())` at `QuestiePlayer.lua:123/132`
+  is the unfinished N5 rewrite; per-loop `Questie.db.profile` reads in
+  `RescaleIcon` and `QuestieNameplate:RedrawIcons` are PP2 candidates.
+
+## 11.3 — Coverage statement (honest)
+
+Read end-to-end across passes 9–11: all logic files ≤ ~600 lines plus the named
+hot files. **Not** read line-by-line (mechanically scanned + targeted-read only):
+the 5 giants (`QuestieLearner`, `QuestieTracker`, `QuestieQuest`, `QuestieDB`,
+`QuestieComms`), the large `Options/*` and `Journey/*` UI (user-triggered, not
+per-frame), the `Tracker/*` UI sub-files (fragile, just-fixed), and `Compat/*`
+data tables (`UiMapData`, `QuestReward`, `QuestTag` — pure data). The 173 data
+files were verified-as-data. Every file was covered by the per-file mechanical
+scan for all 5.0/bug patterns.
+
+---
+
+# Pass-12 Addendum — Re-review Gap Fill (2026-06-04)
+
+This pass re-reviewed the report against the current repo with a narrower rule:
+only add findings that have direct source evidence and either were absent from the
+report or were present in the body but dropped from the consolidated implementation
+plan.
+
+## 12.1 — Plan omissions from already-proven findings
+
+These were already proven earlier in the report, but the final phase map at the
+bottom lost them:
+
+- **B4 was dropped from Phase 1:** `Database/QuestieDB.lua:1903` captures
+  `UnitFactionGroup("player")` at module load. The body correctly says this
+  needs in-game verification because `factionReactions.A/.H` can become nil if
+  the file loads before the player faction is available. Keep it as a
+  verification-gated Phase 1 item.
+- **P3 was mislabeled in Phase 4:** P3 is the front-removal queue work
+  (`tremove(t, 1)` / `table.remove(t, 1)`) from §8.4, not a tracker-only item.
+  It belongs in measured Phase 3, with tracker-adjacent sites still treated
+  cautiously.
+- **P6 was omitted entirely:** the `tinsert(t, 1, x)` front-insert work at
+  `Tooltip.lua:437`, `MapIconTooltip.lua:188,889`, and `QuestieDB.lua:1710` is
+  in §8.4 but missing from the final plan.
+- **PP6 / N6 were omitted from the phase map:** the name-fallback full-NPC scan
+  in `QuestieQuestPrivates.lua` is minor, but should still be tracked as measured
+  Phase 3 or Phase 4 depending on whether Ascension learner code is being touched.
+
+## 12.2 — NEW: expensive debug diagnostics run even when debug output is disabled
+
+`Questie:Debug` short-circuits internally (`Questie.lua:160-166`), but Lua
+evaluates function arguments before entering `Questie:Debug`. Therefore expensive
+arguments still run even when debug output is disabled.
+
+Evidence:
+
+- `Modules/QuestieInit.lua:112-124` defines `_dbStats(t)`, which scans a whole DB
+  table to count entries and min/max IDs.
+- `Modules/QuestieInit.lua:131,132,138,292` call `_dbStats(...)` inside string
+  concatenations passed to `Questie:Debug`. These scans happen before
+  `Questie:Debug` can return.
+- `Modules/QuestieLearner.lua:1972-1979` scans all `QuestieDB.npcDataOverrides`
+  to compute `spawnOverrideCount`, then only uses that value in a debug call.
+
+**Better alternative:** add a cheap predicate helper, e.g. `Questie:IsDebugEnabled(level)`,
+or local guards at the call sites before doing expensive diagnostics. This is
+logic-preserving and should be a low-risk Phase 1/3a item.
+
+## 12.3 — NEW correction: raw `#` count misses Turtle-loaded QuestieMenu files
+
+The final §9.1 count says raw `#` is **33 files / 134 sites**, but at least two
+Turtle-loaded files were not accounted for in the final compatibility ledger:
+
+| File | Raw `#` sites | Turtle TOC evidence |
+|---|---:|---|
+| `Modules/QuestieMenu/Townsfolk.lua` | 5 (`:35`, `:154`, `:245`, `:335`, `:432`) | `Questie-X-Turtle.toc:199` |
+| `Modules/QuestieMenu/QuestieMenu.lua` | 1 (`:117`) | `Questie-X-Turtle.toc:204` |
+
+`Townsfolk.lua` is not data-only: `QuestieInit.lua:142` calls
+`Townsfolk.Initialize()` during database boot, and the file also does large DB
+scans (`QuestieDB.npcData`, `npcDataOverrides`, `itemData`). If Phase 0 proves a
+strict Lua 5.0 target, Phase 2 must be driven from the actual TOC file list rather
+than the stale 33/134 count.
+
+## 12.4 — NEW: `QuestieLearner:GetNPCIdByName` is another full-NPC name scan
+
+Separate from PP6/N6's `monster()` fallback, `QuestieLearner:GetNPCIdByName`
+(`Modules/QuestieLearner.lua:2473-2494`) scans:
+
+1. all `QuestieDB.npcDataOverrides`, lowercasing `data[1]`;
+2. then all base `QuestieDB.npcData`, lowercasing `data[1]`.
+
+Call sites:
+
+- `Modules/QuestieLearner.lua:2609` during `OnQuestAccepted`;
+- `Modules/QuestieLearner.lua:3519` during `ScanExistingQuestLog`, which is
+  scheduled one second after learner initialization.
+
+This is not a per-frame hot path, but it can multiply by objective count and
+quest-log size. If Ascension learner work is already being touched, build a
+lowercase NPC-name index once and update it when learned overrides are injected.
+Preserve override precedence over base DB entries.
+
+## 12.5 — Pass-12 ledger
+
+| ID | Location | Action | Risk |
+|---|---|---|---|
+| H1 | final phase map | restore B4, P3, P6, PP6/N6 | zero |
+| H2 | `QuestieInit._dbStats`, learner `spawnOverrideCount` | guard expensive debug-only computations | low |
+| H3 | `Townsfolk.lua`, `QuestieMenu.lua` | add to Phase 2 raw-`#` remediation; use TOC-driven grep | low if mechanical |
+| H4 | `QuestieLearner:GetNPCIdByName` | add measured learner name-index/cache item | medium; learner is fragile |

+
+# Pass-13 Implementation Update - QuestieLearner kill/loot stutter mitigation (2026-06-04)
+
+This pass was driven by live reports from Elwynn Forest / Redridge players:
+
+- small-map lag with Questie enabled;
+- boar kill + loot stutters with Questie enabled;
+- no stutter after disabling the WotLK DB addon while keeping Ascension DB and
+  Questie enabled.
+
+The strongest code-backed hypothesis was Xurkon's: QuestieLearner was doing too
+much work on every kill/loot burst. The previous implementation updated learner
+saved data, injected/merged live `QuestieDB.npcDataOverrides`, cleared
+`QuestieDB.private.npcCache[npcId]`, invalidated active quest spawn lists, and
+broadcast learner data from the same hot path.
+
+## 13.1 - Implemented mitigation
+
+Changed `Modules/QuestieLearner.lua`:
+
+- Added a 0.5s coalescing window for NPC live DB updates. `LearnNPC` still
+  records saved learner evidence immediately, but live override injection,
+  `npcCache` clearing, and active objective spawn-list invalidation now flush
+  once per NPC per burst instead of once per kill/log/loot-triggered call.
+- Added deep-copying when learner NPC data is copied into live overrides. This
+  prevents `QuestieDB.npcDataOverrides[npcId]` from aliasing the saved learner
+  table and mutating "before flush" during later kills.
+- Routed `_MergeSpawnEvidence` cache clearing through the same coalesced NPC
+  live-update path.
+- Added a 2s coalescing window for learner outgoing broadcasts. Repeated
+  `LearnNPC`, `LearnItem`, `LearnObject`, or `LearnQuest` updates for the same
+  entity keep only the latest pending payload before calling
+  `QuestieLearnerComms:BroadcastLearnedData`. If the burst began as a first
+  discovery, the queued message preserves the original `NEW` op while still
+  sending the latest payload. This specifically covers the loot handler path
+  where quest-item loot calls `LearnItem(...)`.
+
+## 13.2 - Evidence and verification
+
+New regression coverage:
+
+- `Tests/QuestieLearner_performance_spec.lua` proves repeated `LearnNPC` calls do
+  not immediately populate `QuestieDB.npcDataOverrides` or clear
+  `QuestieDB.private.npcCache`; the live update happens only when the queued
+  timer flushes.
+- The same spec proves repeated learner broadcasts coalesce into one latest
+  payload while preserving the first-discovery `NEW` op.
+
+Focused verification run:
+
+```text
+busted Tests\QuestieLearner_performance_spec.lua Tests\QuestieDB_suppression_spec.lua
+6 successes / 0 failures / 0 errors / 0 pending
+```
+
+## 13.3 - What this does and does not prove
+
+This fix directly addresses the kill/loot learner churn that could explain
+short stutters while killing and looting boars, especially with the large WotLK
+DB enabled. It does **not** prove the WotLK DB addon is the sole cause; it proves
+the learner was synchronously touching live DB/cache/map/comms surfaces in the
+reported hot path.
+
+If field reports still reproduce stutters after this patch, continue in this
+order:
+
+1. Batch item/object live override updates the same way NPC live updates are now
+   batched.
+2. Add the Pass-12 H2 debug guards for `_dbStats(...)` and learner
+   `spawnOverrideCount`.
+3. Add the Pass-12 H4 lowercase NPC-name index for
+   `QuestieLearner:GetNPCIdByName`.
+4. Coalesce inbound learner network `InjectLearnedData` calls from P9 so multiple
+   incoming payloads produce one merge pass per burst.
+
+## 13.4 - Updated implementation-plan status

+
+Created branch:
+
+```text
+codex/questie-learner-comms-improvements
+```
+
+Repo-local Git identity was set before commit/push work:
+
+```text
+Xurkon <Kancerous@gmail.com>
+```
+
+## 14.1 - Scope added to the branch
+
+This branch now contains:
+
+- Pass-13 QuestieLearner kill/loot stutter mitigation;
+- outgoing learner comm burst coalescing while preserving first-discovery `NEW`
+  semantics;
+- removal of active Turtle-specific support paths now that TurtleWoW support is
+  gone.
+
+## 14.2 - Turtle cleanup performed
+
+Removed active Turtle support references from:
+
+- `Modules/QuestieServer.lua`: removed `Questie.IsTurtle` detection, TurtleDB
+  expected-plugin flavor, TurtleDB plugin scan entry, and Turtle debug output.
+- `Modules/QuestieInit.lua`: removed `Questie.IsTurtle` from custom-server
+  compilation/defer checks.
+- `Modules/QuestieLearnerExport.lua` and
+  `Modules/Options/DatabaseTab/QuestieOptionsDatabase.lua`: removed Turtle
+  learner export/database bucket labels.
+- `Modules/Options/CreditsTab/QuestieOptionsCredits.lua`: removed TurtleWoW from
+  current credits copy.
+- `Modules/Libs/QuestiePluginAPI.lua`, `Modules/QuestieCompat.lua`, and
+  `Modules/Libs/QuestieLoader.lua`: replaced Turtle-specific comments with
+  generic legacy/custom-client wording so universal Lua compatibility remains.
+- `CHANGELOG.md` and `docs/changelog.html`: scrubbed historical support wording
+  that named TurtleWoW directly.
+
+The ignored local file `Questie-X-Turtle.toc` was deleted from disk. It was
+already excluded by `.gitignore`, so there is no tracked delete for it.
+
+## 14.3 - Remaining intentional references
+
+The only remaining `Turtle` grep hit in tracked source is an actual game item:
+
+```text
+Modules/QuestieDebugOffer.lua: Pattern: Turtle Scale Gloves
+```
+
+Do not remove game-content names just because they contain the word "Turtle".

+
+# Pass-15 Implementation Update - inbound learner merge batching and low-risk guards (2026-06-04)
+
+This pass landed the remaining learner/comms follow-ups that were the next best
+steps from the audit.
+
+## 15.1 - Implemented fixes
+
+Changed `Modules/QuestieLearner.lua`:
+
+- **P9 inbound merge batching:** `HandleNetworkData` now queues incoming
+  payloads by `typ:id` and flushes them once per burst window instead of calling
+  `InjectLearnedData()` on every packet.
+- **H4 learner name index:** `GetNPCIdByName` now uses a cached lowercase name
+  index with override precedence instead of scanning all NPC overrides/base data
+  on every lookup.
+- **NPC-name index invalidation:** the learner marks the name index dirty when
+  learned NPC names are added or changed, so cached lookups stay correct after
+  new data arrives.
+
+Changed `Modules/QuestieInit.lua`:
+
+- **H2 debug guards:** expensive `_dbStats(...)` scans are now wrapped behind a
+  debug-enabled check, so the tables are no longer walked when debug output is
+  off.
+
+Changed `Modules/QuestieLearner.lua`:
+
+- **H2 debug guard:** the `spawnOverrideCount` scan in `InjectLearnedData()`
+  now runs only when debug output is enabled.
+
+## 15.2 - Evidence and verification
+
+New regression coverage:
+
+- `Tests/QuestieLearner_performance_spec.lua` now proves repeated inbound
+  network merges coalesce into one inject pass, in addition to the existing
+  kill-path and broadcast batching coverage.
+
+Focused verification run:
+
+```text

+# Pass-16 Implementation Update - QuestieLearnerComms queue head/tail draining (2026-06-04)
+
+This pass took the smaller but still real comms hot-path win: the queue plumbing
+inside `Modules/Network/QuestieLearnerComms.lua`.
+
+## 16.1 - Implemented fix
+
+Changed `Modules/Network/QuestieLearnerComms.lua`:
+
+- Replaced the outgoing `rateLimitQueue` and incoming `incomingMessageQueue`
+  front-removal behavior with head/tail indexing.
+- `ProcessQueues()` now drains from the head in O(1) per pop instead of
+  `table.remove(..., 1)` shifting the remaining array on every tick.
+- Queue state resets back to the initial indices when each queue becomes empty,
+  so the optimization does not change external behavior or accumulate stale
+  indices.
+
+## 16.2 - Evidence and verification
+

+
+- `Tests/QuestieLearner_performance_spec.lua` now proves the learner comms
+  queue drains outgoing broadcasts and incoming messages in FIFO order without

+# Pass-17 Implementation Update - QuestieComms incremental packet sizing (2026-06-04)
+
+This pass took the larger remaining comms performance win from the audit: the
+quest-list broadcast paths in `Modules/Network/QuestieComms.lua`.
+
+## 17.1 - Implemented fix
+
+Changed `Modules/Network/QuestieComms.lua`:
+
+- Added incremental packet-size estimation helpers so the broadcast builders no
+  longer re-serialize the entire growing `rawQuestList` on every quest.
+- `BroadcastQuestLog()` now estimates each quest packet once, tracks the running
+  block size, and splits before appending when the estimated size would cross
+  the threshold.
+- `BroadcastQuestLogV2()` uses the same incremental strategy with a V2 packet
+  size estimator instead of calling `QuestieSerializer:Serialize(rawQuestList)`
+  inside the loop.
+- The existing block-sending behavior is preserved, including the staggered
+  ticker and follow-on broadcast queue.
+
+Also cleaned up a stale audit assertion tied to the removed Turtle TOC file so
+the snapshot now matches the repo state after Turtle support removal.
+
+## 17.2 - Evidence and verification
+
+Regression coverage:
+
+- `Tests/AuditFindings_spec.lua` now asserts that the old `rawQuestList`

+
+## 18.1 - Implemented fix
+
+Changed `Modules/Network/QuestieComms.lua`:

+- Replaced the `_nextBroadcastData` and `_nextBroadcastDataV2` front-removal
+  follow-up queues with the same head/tail queue helper, so the module no longer

+
+# Pass-21 Implementation Update - user-tunable QuestieLearner performance settings (2026-06-04)
+
+This pass added real Advanced-tab controls for the learner/comms work instead
+of leaving the new batching delays hardcoded.
+
+## 21.1 - Implemented fix
+
+Changed `Modules/QuestieLearner.lua`:
+
+- Added learner settings defaults/backfills for:
+  - `performanceMode`
+  - `pinRefreshDelay`
+  - `pinRefreshMode`
+  - `liveNpcUpdateDelay`
+  - `learnerCommsIntensity`
+- `pinRefreshDelay` now controls the coalesced active-quest pin refresh timer.
+- `pinRefreshMode` can now avoid live pin redraws entirely with `manual`.
+- Frame unloads caused by learner spawn invalidation now wait for the same
+  batched pin refresh unless `pinRefreshMode` is `immediate`.
+- `liveNpcUpdateDelay` now controls both NPC live DB/cache update batching and
+  inbound network merge batching.
+- Learner outgoing broadcasts now respect both the existing
+  `Questie.db.profile.learnerBroadcast` toggle and the new comms intensity.
+
+Changed `Modules/Network/QuestieLearnerComms.lua`:
+
+- Added comms tuning levels for `off`, `low`, `normal`, and `fast`.
+- The setting now controls outgoing send interval, token capacity, and incoming
+  messages processed per tick/combat tick.
+- `off` skips outgoing queueing and incoming learner comm processing.
+
+Changed `Modules/Options/AdvancedTab/QuestieOptionsAdvanced.lua`:
+
+- Added a new `QuestieLearner Performance` section under Advanced.
+- Added `Performance Mode` presets: Realtime, Balanced, Low Impact, Manual.
+- Added controls for pin refresh behavior, pin refresh delay, live NPC update
+  delay, minimum kills before learned pins, and learner comms intensity.
+
+Changed `Modules/Options/QuestieOptionsDefaults.lua`:
+
+- Added a real default for `learnerBroadcast = true`, matching the existing
+  Database-tab broadcast toggle.
+
+Changed local gitignored verification file
+`Tests/QuestieLearner_performance_spec.lua`:
+
+- Added direct public-flow coverage for the cross-link engine:
+  - quest learned first, then starter/finisher NPCs and objects learned later
+    back-link into `npc[10]`, `npc[11]`, `object[2]`, and `object[3]`;
+  - those same links also appear in the live `QuestieDB.*DataOverrides`;
+  - active quest pin refreshes remain coalesced to one `QuestieQuest:UpdateQuest`
+    call while multiple cross-links are created;
+  - item objective drop chains (`quest[10][3]` + `item[2]`) add the drop NPC to
+    creature objectives (`quest[10][1]`) without duplicating entries when the
+    same drop is learned again.
+- This test file is intentionally local/dev-only because `Tests/` is currently
+  gitignored in this branch. Do not assume these specs are committed unless a
+  future branch deliberately force-adds the test harness.

+- Cross-link tests prove the local learner cross-link engine still works for the

+# Pass-22 Implementation Update - stop bystander kills from refreshing learner pins (2026-06-04)
+
+This pass was triggered by live feedback that QuestieLearner felt worse after
+the performance settings pass: pins were still refreshing on every kill, and
+even kills by other nearby players appeared to refresh the local player's pins.
+
+## 22.1 - Verified root cause
+
+The prior batching work was functioning mechanically: the only remaining direct
+`QuestieQuest:UpdateQuest(questId)` call in `Modules/QuestieLearner.lua` is still
+inside `_FlushActiveQuestPins()`. However, the event source feeding that batch
+was too broad.
+
+`QuestieLearner:OnCombatLogEvent(...)` accepted both:
+
+- `PARTY_KILL`
+- `UNIT_DIED`
+
+and then unconditionally called:
+
+- `LearnNPC(...)`
+- `_StoreGuidSpawnEvidence(...)`
+- `_MergeSpawnEvidence(...)`
+
+`UNIT_DIED` fires for visible nearby mob deaths, including mobs killed by other
+players. That meant bystander deaths could still promote learner spawn evidence,
+flush live NPC overrides, invalidate active quest spawn lists, and queue a
+batched pin redraw. The redraw was batched, but it was still being triggered by
+too many non-local events.
+
+Network comms were also reviewed. Incoming learner comms can merge saved data
+and call `InjectLearnedData()`, but that path intentionally does not promote NPC
+spawn coordinates into live `npcDataOverrides[...][7]`; therefore remote comms
+are less likely to be the direct pin-redraw trigger than local combat-log
+`UNIT_DIED` visibility.
+
+## 22.2 - Implemented fix
+
+Changed `Modules/QuestieLearner.lua`:
+
+- `UNIT_DIED` still records short-lived `recentKills` evidence for later quest
+  objective progress correlation.
+- `UNIT_DIED` now exits before `LearnNPC`, `_StoreGuidSpawnEvidence`, and
+  `_MergeSpawnEvidence`.
+- `PARTY_KILL` keeps the existing learner behavior, so player/group kills still
+  learn spawn data and use the already-batched live update path.
+
+This preserves existing functionality where possible:
+
+- If a nearby death does not advance the player's quest, it no longer touches
+  learner live pin refresh.
+- If a nearby death does advance the player's quest via a later quest-objective
+  update, the existing `recentKills` correlation path can still learn the NPC.
+- Local/group kills still feed learner immediately through `PARTY_KILL`.
+
+All code remains Lua 5.0-compatible.
+
+## 22.3 - Added local verification
+
+Updated gitignored dev spec `Tests/QuestieLearner_performance_spec.lua`:
+
+- Added regression coverage proving `UNIT_DIED` from a visible bystander death
+  does not create learned NPC data, does not create live NPC overrides, and does
+  not queue learner timers/pin refresh work.
+- Added paired coverage proving `PARTY_KILL` still learns the NPC and queues the
+  existing batched learner timers.

+
+## 22.4 - Suggestions if stutter remains after this patch
+
+1. Default new/low-end users to `Low Impact` instead of `Balanced`, or make the
+   first-run default `pinRefreshDelay = 2.0`, `liveNpcUpdateDelay = 2.0`, and
+   `minConfidencePins = 3`. This trades slower live pin learning for much lower
+   frame churn in dense zones.
+2. Add a separate `Live Learned Pin Updates` toggle that maps to
+   `pinRefreshMode = "manual"`. This gives players a clear emergency switch:
+   learn data now, redraw pins later/reload.
+3. Add a developer-only counter for `_RefreshActiveQuestPins`,
+   `_InvalidateSpawnListsForNPC`, and `_FlushActiveQuestPins` so testers can
+   quantify pin refreshes in game with the macro report.
+4. Tighten incoming network merge semantics so `_ApplyIncomingNetworkMerge`
+   returns `true` only when data actually changed, not merely because `op` is
+   `NEW` or `UPDATE`. This is lower priority for pin redraw than the `UNIT_DIED`
+   fix, but it would reduce unnecessary `InjectLearnedData()` work from noisy
+   peers.

+
+# Pass-23 Implementation Update - arrow profiler red entries (2026-06-04)
+
+This pass investigated an in-game profiler screenshot with red entries around:
+
+- `QuestieCompat.HBD.GetPlayerWorldPosition`
+- `QuestieArrow.Refresh`
+- `QuestieArrow.UpdateNearestTargets`
+- `QuestieCompat.GetCurrentPlayerPosition`
+- `QuestieCompat.HBD.GetPlayerZonePosition`
+- `QuestieCompat.HBD.GetWorldCoordinatesFromZone`
+- `QuestieCompat.HBD.GetWorldDistance`
+- `ZoneDB.GetUiMapIdByAreaId`
+- `QuestieCoords.WriteCoords`
+- `TrackerUtils.GetNearestQuestItemId`
+- `QuestieLearnerComms.private.ProcessQueues`
+
+## 23.1 - Root-cause interpretation
+
+The hottest cluster is arrow-related, not learner-related.
+
+`QuestieArrow:Refresh()` calls `QuestieArrow:UpdateNearestTargets()`. The
+nearest-target scan evaluates objectives and finishers across the active quest
+log, then converts every candidate spawn into world coordinates and distance:
+
+- `ZoneDB:GetUiMapIdByAreaId(zone)`
+- `HBD:GetWorldCoordinatesFromZone(...)`
+- `HBD:GetWorldDistance(...)`
+
+The profiler showed about 50 arrow refreshes but thousands of HBD/ZoneDB calls.
+That ratio matches a full candidate scan: each refresh can fan out into many
+spawn conversions. The comment in `Modules/Arrow/QuestieArrow.lua` also confirms
+zone filtering is currently disabled because of historical zone ID vs area ID
+mismatch, so the scan does more work than a same-zone-only scan would.
+
+Separately, `QuestieArrow`'s frame `OnUpdate` recalculated the current target's
+world coordinates every throttled tick. That explains why
+`HBD.GetPlayerWorldPosition` and current-position helpers are high-call-count
+even when the full nearest-target scan is only running periodically.
+
+Lower entries reviewed:
+
+- `QuestieCoords.WriteCoords` is the map/minimap coordinate ticker. In the
+  screenshot it is much lower total time than arrow scanning; leave it alone for
+  this pass unless a future profile isolates it with the arrow disabled.
+- `TrackerUtils.GetNearestQuestItemId` is lower total time and likely incidental
+  tracker work. Do not mix tracker changes into this arrow pass.
+- `QuestieLearnerComms.private.ProcessQueues` is low total time in the screenshot
+  and already intensity-gated from Pass-21.
+
+## 23.2 - Implemented fix
+
+Changed `Modules/Arrow/QuestieArrow.lua`:
+
+- Added a per-scan zone-to-UiMap cache for `ZoneDB:GetUiMapIdByAreaId(zone)`.
+  Multiple spawns in the same zone now reuse the same resolved UiMap ID during a
+  single nearest-target scan.
+- Added `_AddArrowTarget(...)` so every collected target stores:
+  - zone coordinates;
+  - UiMap ID;
+  - already-computed world X/Y/instance;
+  - already-computed distance.
+- The arrow frame `OnUpdate` now reuses the target's cached world X/Y/instance.
+  It only falls back to `HBD:GetWorldCoordinatesFromZone(...)` if the target was
+  created without cached world coordinates, such as a manual target path.
+- Hoisted the `table.sort(sortedTargets, ...)` comparator into
+  `_SortTargetByDistance` so the refresh path no longer allocates a comparator
+  closure each sort.
+- Avoided calling `objectiveFrame.distance:SetText(...)` when the formatted
+  distance string has not changed.
+
+This pass intentionally did **not** re-enable zone filtering. That could provide
+a bigger reduction, but it changes target-selection semantics and needs live
+validation across Ascension/custom maps, dungeons, and zone/area ID aliases.
+
+## 23.3 - Expected profiler impact
+
+Expected improvements:
+
+- Fewer `ZoneDB.GetUiMapIdByAreaId` calls inside `UpdateNearestTargets`, because
+  repeated spawns in the same zone are cached per scan.
+- Fewer `HBD.GetWorldCoordinatesFromZone` calls during arrow frame updates,
+  because the current target keeps cached world coordinates.
+- Less UI churn from distance text updates when the text did not change.
+- Slightly less allocation pressure from the hoisted sort comparator and unified
+  target insertion helper.
+
+Expected remaining red/green entries:
+
+- `HBD.GetPlayerWorldPosition` may still appear frequently while the arrow is
+  visible because the arrow must rotate/distance-update as the player moves.
+- `HBD.GetWorldDistance` remains necessary for candidate ranking and live
+  distance updates.
+- `QuestieArrow.UpdateNearestTargets` can still be expensive in large quest logs
+  because zone filtering remains disabled.

+3. Add a safe same-map/same-zone candidate preference: first scan current UiMap
+   candidates, then fall back to cross-zone candidates only if no local target
+   exists. This should reduce the disabled-zone-filter cost without breaking
+   cross-zone quest arrows.
+4. Add temporary dev counters for:
+   - `QuestieArrow:Refresh()`
+   - `QuestieArrow:UpdateNearestTargets()`
+   - `_GetUiMapIdForZone()` cache hits/misses
+   - target count before sort
+   These counters would let testers prove whether the profile improves in-game.

+# Pass-24 Implementation Update - Arrow performance settings (2026-06-04)
+
+This pass compared the Pass-23 arrow optimization against earlier audit
+recommendations before making additional changes.
+
+## 24.1 - Audit comparison
+
+The Pass-23 patch matched the best low-risk audit recommendations:
+
+- PP3: `QuestieArrow` no longer allocates an inline `table.sort` comparator per
+  nearest-target refresh. It uses `_SortTargetByDistance`.
+- PP4: the arrow no longer blindly calls `FontString:SetText(...)` for unchanged
+  distance strings.
+- The profiler-specific Pass-23 recommendation to cache target world coordinates
+  was also implemented, reducing repeated `HBD:GetWorldCoordinatesFromZone(...)`
+  calls during arrow frame updates.
+
+The larger possible optimization, same-zone/same-map filtering, was intentionally
+not used yet. The existing arrow code explicitly disabled zone filtering because
+area IDs, UiMap IDs, and custom Ascension map IDs can mismatch. Re-enabling hard
+filtering could make the arrow ignore valid cross-zone, dungeon, or custom-map
+targets. The safer next step is to expose throttle settings so users can reduce
+scan/update frequency without changing target correctness.
+
+## 24.2 - Implemented fix
+
+Changed `Modules/Arrow/QuestieArrow.lua`:
+
+- Replaced fixed constants with clamped profile-backed getters:
+  - `arrowUpdateThrottle` controls arrow rotation/distance update frequency.
+  - `arrowRecalcInterval` controls full nearest-target scan frequency.
+  - `arrowTrackerRefreshThrottle` controls refresh bursts triggered by tracker
+    updates.
+- Defaults preserve previous behavior:
+  - `arrowUpdateThrottle = 0.05`
+  - `arrowRecalcInterval = 1.0`
+  - `arrowTrackerRefreshThrottle = 0.5`
+- Runtime clamps protect against bad SavedVariables:
+  - movement update: `0.03` to `0.5` seconds;
+  - target scan: `0.5` to `10.0` seconds;
+  - tracker refresh: `0.25` to `5.0` seconds.
+
+Changed `Modules/Options/QuestieOptionsDefaults.lua`:
+
+- Added defaults for the three new Arrow performance settings.
+
+Changed `Modules/Options/ArrowTab/QuestieOptionsArrow.lua`:
+
+- Added an `Arrow Performance` section under the Arrow tab.
+- Added sliders:
+  - `Arrow Movement Update Interval`;
+  - `Target Scan Interval`;
+  - `Tracker Refresh Throttle`.
+
+Changed local gitignored verification file `Tests/AuditFindings_spec.lua`:
+
+- Added PP7 assertions proving the runtime getters, Arrow-tab controls, and
+  defaults exist.
+
+All new runtime code remains Lua 5.0-compatible; this pass did not introduce
+new `#`, `%`, `...`, `goto`, `select`, or `table.unpack` usage.
+
+## 24.3 - Recommended user settings
+
+For players seeing red profiler entries or FPS drops with the arrow enabled:
+
+- Start with `Target Scan Interval = 3.0s`.
+- Set `Tracker Refresh Throttle = 1.5s`.
+- Set `Arrow Movement Update Interval = 0.10s`.
+
+For very low-end machines or crowded zones:
+
+- `Target Scan Interval = 5.0s`.
+- `Tracker Refresh Throttle = 2.0s`.
+- `Arrow Movement Update Interval = 0.15s` to `0.20s`.
+
+Tradeoff: the arrow still points correctly, but it may take longer to switch to
+a newly nearest objective and may rotate/update distance less smoothly.
+
+## 24.4 - Verification
+
+Focused verification run:
+
+```text
+busted Tests\QuestieArrow_spec.lua Tests\AuditFindings_spec.lua Tests\QuestieLearner_performance_spec.lua Tests\QuestieDB_suppression_spec.lua
+55 successes / 0 failures / 0 errors / 0 pending

+```text
+selene Modules\Arrow\QuestieArrow.lua Modules\Options\ArrowTab\QuestieOptionsArrow.lua Modules\Options\QuestieOptionsDefaults.lua
+0 errors / 10 warnings / 0 parse errors
+```
+
+Selene warnings are existing one-line style warnings in `QuestieArrow.lua`, not
+new parser/runtime errors from this pass.
+
+## 24.5 - Remaining next step
+
+If the arrow still dominates profiles after users raise these throttles, the
+next best code change is a same-map-first scan:
+
+1. scan candidates on the player's current UiMap/normalized area first;
+2. if local candidates exist, sort only those;
+3. if none exist, fall back to the existing cross-zone scan.
+
+That would reduce candidate volume while preserving cross-zone functionality,
+but it should be live-tested because of Ascension/custom map ID edge cases.
+

+
+# Pass-25 Verification Update - Arrow and Learner options live wiring (2026-06-04)
+
+This pass verified that the Arrow and QuestieLearner performance settings are
+fully wired from options UI to runtime behavior and adjust without requiring a
+reload.
+
+## 25.1 - Arrow wiring verification
+
+Verified path:
+
+- Defaults:
+  - `Modules/Options/QuestieOptionsDefaults.lua`
+  - `arrowUpdateThrottle = 0.05`
+  - `arrowRecalcInterval = 1.0`
+  - `arrowTrackerRefreshThrottle = 0.5`
+- Options UI:
+  - `Modules/Options/ArrowTab/QuestieOptionsArrow.lua`
+  - `Arrow Movement Update Interval`
+  - `Target Scan Interval`
+  - `Tracker Refresh Throttle`
+- Runtime:
+  - `Modules/Arrow/QuestieArrow.lua`
+  - `_GetArrowUpdateThrottle()` is read inside the arrow frame `OnUpdate`.
+  - `_GetArrowRecalcInterval()` is read inside the driver frame full target
+    scan scheduler.
+  - `_GetArrowTrackerRefreshThrottle()` is read inside the tracker-update hook.
+
+Conclusion: Arrow settings are live-read on every relevant throttle check. New
+values affect future arrow updates/target scans without reload. The
+`Target Scan Interval` setter also calls `QuestieArrow:Refresh()` so the player
+gets an immediate recalculation after changing the scan interval.
+
+No Arrow runtime patch was required in this pass.
+
+## 25.2 - Learner wiring verification
+
+Verified path:
+
+- Defaults/backfills:
+  - `Modules/QuestieLearner.lua`
+  - `performanceMode`
+  - `pinRefreshDelay`
+  - `pinRefreshMode`
+  - `liveNpcUpdateDelay`
+  - `learnerCommsIntensity`
+- Options UI:
+  - `Modules/Options/AdvancedTab/QuestieOptionsAdvanced.lua`
+  - `Performance Mode`
+  - `Pin Refresh Behavior`
+  - `Pin Refresh Delay`
+  - `Live NPC Update Delay`
+  - `Minimum Kills Before Learned Pins`
+  - `Learner Comms Intensity`
+- Runtime:
+  - `pinRefreshMode` gates scheduling and now also gates already queued flushes.
+  - `pinRefreshDelay` is read when scheduling pin refresh timers.
+  - `liveNpcUpdateDelay` is read when scheduling NPC live update and network merge
+    timers.
+  - `learnerCommsIntensity` is read by outgoing learner broadcasts and learner
+    comms queue processing.
+  - `minConfidencePins` is read before learned NPC spawn evidence is promoted to
+    live overrides.
+
+## 25.3 - Issues found and fixed
+
+1. Preset/comms desync:
+
+   If a player set `Learner Comms Intensity = Off`, the setter correctly set
+   `Questie.db.profile.learnerBroadcast = false`. However, choosing a preset
+   such as `Balanced` or `Realtime` later changed `learnerCommsIntensity` back to
+   `normal` or `fast` without re-enabling `learnerBroadcast`. The UI could show
+   comms as active while outgoing learner broadcasts remained disabled.
+
+   Fix:
+
+   - `ApplyLearnerPerformancePreset("realtime"|"balanced"|"low")` now sets
+     `Questie.db.profile.learnerBroadcast = true`.
+   - Manual mode leaves existing values alone.
+
+2. Manual pin refresh emergency stop:
+
+   `pinRefreshMode = "manual"` prevented new refresh scheduling, but if a
+   batched refresh timer had already been queued, that pending flush could still
+   run once after the user switched to Manual.
+
+   Fix:
+
+   - `_FlushActiveQuestPins()` now re-checks `pinRefreshMode`.
+   - If the setting is `manual`, the pending frame-unload table is cleared and
+     no `QuestieQuest:UpdateQuest(...)` call is made.
+
+## 25.4 - Added local verification
+
+Updated gitignored dev specs:
+
+- `Tests/QuestieLearner_performance_spec.lua`
+  - Added regression coverage proving a queued learner pin refresh is suppressed
+    if the user switches to Manual before the timer fires.
+- `Tests/AuditFindings_spec.lua`
+  - Added an assertion that learner presets keep comms intensity and
+    `learnerBroadcast` synchronized.

+# Pass-26 Implementation Update - QuestieComms performance options (2026-06-04)
+
+This pass added live QuestieComms performance controls under Advanced and split
+the work into individual commits for easier revert/bisect:
+
+- `c6bfa95 perf: wire questie comms throttles`
+- `a113791 perf: add questie comms disable gate`
+- `b62def5 feat: add questie comms performance options`
+- `ccd2bc1 refactor: centralize performance options`
+
+## 26.1 - Commit strategy note
+
+Going forward, changes should be committed one logical unit at a time. This pass
+used three separate commits:
+
+1. runtime/default support for QuestieComms throttles;
+2. runtime/default support for disabling QuestieComms entirely;
+3. Advanced-tab UI exposure.
+4. centralization of all performance tuners into the Advanced tab.
+
+That makes reverting UI exposure independent from reverting runtime gates.
+
+## 26.2 - Implemented runtime settings
+
+Changed `Modules/Network/QuestieComms.lua`:
+
+- Added clamped profile-backed getters:
+  - `questieCommsQuestListPacketSize`
+  - `questieCommsQuestListInitialJitter`
+  - `questieCommsQuestListBlockInterval`
+  - `questieCommsEnabled`
+- Replaced hardcoded full quest-list block size with
+  `GetQuestListPacketSizeLimit()`.
+- Replaced hardcoded initial response jitter (`random() * 3`) with
+  `GetQuestListInitialJitter()`.
+- Replaced hardcoded full quest-list block ticker interval (`3`) with
+  `GetQuestListBlockInterval()`.
+- Added a live `IsQuestieCommsEnabled()` gate to:
+  - quest update broadcasts;
+  - quest remove broadcasts;
+  - yell progress;
+  - legacy full quest-list broadcast;
+  - V2 full quest-list broadcast;
+  - full quest-list requests;
+  - low-level packet broadcast;
+  - incoming QuestieComms receive handler.
+
+The master enabled toggle is live-read at send/receive time, so disabling
+QuestieComms takes effect immediately without reload. Already queued full
+quest-list ticker callbacks may continue to drain their local queues, but every
+packet write routes through `_QuestieComms:Broadcast(...)`, which now checks the
+enabled flag before sending.
+
+Changed `Modules/Options/QuestieOptionsDefaults.lua`:
+
+- Added defaults preserving previous behavior:
+  - `questieCommsEnabled = true`
+  - `questieCommsQuestListPacketSize = 200`
+  - `questieCommsQuestListInitialJitter = 3`
+  - `questieCommsQuestListBlockInterval = 3`
+
+## 26.3 - Implemented Advanced-tab options
+
+Changed `Modules/Options/AdvancedTab/QuestieOptionsAdvanced.lua`:
+
+- Added `QuestieComms Performance` section.
+- Added `Enable QuestieComms` toggle.
+- Added sliders:
+  - `Quest List Packet Size`;
+  - `Quest List Initial Jitter`;
+  - `Quest List Block Interval`.
+- Sliders are disabled visually when `Enable QuestieComms` is off.
+
+These settings are intentionally under Advanced because they control network and
+CPU burst behavior rather than normal user quest display behavior.
+
+Important UI convention from this pass:
+
+- All performance/intensity tuners should live in `Advanced`.
+- The `Advanced` tab now contains:
+  - `QuestieLearner Performance`;
+  - `QuestieArrow Performance`;
+  - `QuestieComms Performance`.
+- The Arrow tab no longer owns Arrow performance sliders. It should remain for
+  normal arrow display/appearance/target behavior.
+- If future performance controls are added, add them to Advanced rather than
+  scattering them into feature-specific tabs.
+
+## 26.4 - Settings behavior
+
+Recommended low-end/crowded-group starting point:
+
+- `Enable QuestieComms = On` unless the player wants to completely opt out.
+- `Quest List Packet Size = 150`
+- `Quest List Initial Jitter = 5.0s`
+- `Quest List Block Interval = 5.0s`
+
+Emergency/no-comms mode:
+
+- `Enable QuestieComms = Off`
+
+Tradeoff:
+
+- Lower packet size can increase block count but reduces per-packet serialization
+  and transmission size.
+- Higher jitter/block interval reduces bursts but makes full quest-list syncs
+  slower.
+- Disabling QuestieComms stops group quest-progress sharing from this module.
+
+## 26.5 - Added local verification
+
+Updated gitignored dev specs:
+
+- `Tests/AuditFindings_spec.lua`
+  - Added assertions proving QuestieComms settings are profile-backed.
+  - Added assertions proving the Advanced controls are exposed.
+- `Tests/QuestieLearner_performance_spec.lua`
+  - Added runtime coverage proving outgoing QuestieComms packets are suppressed
+    immediately when `questieCommsEnabled = false`.

+
+# Implementation Plan (consolidated — how to land everything)
+
+This is the recommended order to incorporate every finding above. It is built
+around three realities: (1) the biggest unknown is **what client/Lua the targets
+actually run**; (2) three subsystems are **fragile** (tracker, minimap/HBD,
+Ascension learner) and out of scope unless explicitly chosen; (3) every change
+should be **bisectable** and guarded by `Tests/AuditFindings_spec.lua`.
+
+## Phase 0 — Decide the target matrix (blocks all 1.12 work)
+
+Run these in-game on each target you intend to support; record the answers.
+
+| Probe | Question it answers |
+|---|---|
+| `/run print(#({1,2,3}))` | Does `#` parse? (gates the raw-`#` work; §12.3 says the 33/134 count is stale) |
+| `/run print((4 % 3))` | Does `%` parse? (gates the 11-file `%` work) |
+| `/run print(bit and bit.band(3,1))` | Is the `bit` library present? (N1) |
+| `/run print(type(strsplit))` | Is `strsplit` present? (N2) |
+| `/run local f=loadstring("return ...") print(f and pcall(f,1))` | Does the `...` expression parse? |
+
+**Decision gate:** if a target errors on `#`/`%`/`...`, it is genuinely Lua 5.0
+and Phase 2 is required for that target. If all print fine, Phase 2 is **skipped
+entirely** (the addon already works there) and you go straight from Phase 1 to
+Phase 3. Do not start Phase 2 before this gate.
+
+## Phase 1 — Zero-risk correctness & hygiene (one commit, all targets)
+
+Independent, mechanical, each guarded by a spec assertion. Land as one commit
+(or the four sub-groups below for clean bisection).
+
+1a. **Pure typos / dedup** — `Questie-X.toc:182` duplicate (B5);
+    `QuestieOptionsTracker.lua:486/522/797` `fadeTickerValue:Cancel()` →
+    `fadeTicker:Cancel()` (B2); strip BOMs from the 3 `Database/Corrections/*`
+    files (B6).
+1b. **Defensive nil-guards** — `QuestieDB.lua:1355` hoist the double `GetQuest`
+    (B1); `QuestieCommsData.lua:49,51` guard `GetNPC/GetObject(...).name` like the
+    item branch (N4).
+1c. **Bounded growth / dead wiring** — wipe `alreadySentBandaid` on login (B3);
+    `QuestieFrame.lua:133` wire `BaseOnUpdate` to `GlowUpdate` **or** delete the
+    dead ticker (B7, pick one); add the unused `questId` param to
+    `Ascension_IsScalingEnabled` to clear the lint (FP1 — cosmetic).
+1d. **Loop-correctness** — `QuestieNameplate.lua:88` change the early `return` to
+    skip-this-entry (G1); same review for the `QuestieQuest.lua:222` early-return
+    (pass-2 item).
+1e. **Verification-gated / debug hygiene** — verify B4 (`QuestieDB.lua:1903`
+    load-time faction capture) in-game, then lazily compute/recompute
+    `factionReactions` if needed; guard expensive debug-only diagnostics before
+    `_dbStats(...)` / `spawnOverrideCount` are computed (H2).
+
+*Verify:* `busted` stays green except the 4 pre-existing ArrowAssets fails;
+invert the matching `[B*]`/`[N4]` spec assertions as each lands. In-game smoke:
+accept/abandon a quest, open a comms tooltip, hover a nameplate.
+
+## Phase 2 — 1.12 / Lua 5.0 remediation (ONLY if Phase 0 says a target needs it)
+
+Order matters — the bootstrap must parse before anything else.
+
+2a. **Runtime gaps first (cheap, high-impact):** add a `bit` shim and a
+    `strsplit` shim to `QuestieCompat`/`QuestieLoader` (N1/N2). For `bit`, mirror
+    the guard XXH already uses; provide pure-Lua `band/bor/bxor/lshift/rshift`.
+    These are nil-index crashes at load (`Questie.lua:1`) so they gate everything.
+2b. **`%` operator (11 files, ~50 sites, 11.1):** replace `a % b` with
+    `math.mod(a, b)` (already shimmed). Start with `QuestieStream.lua` (23) since
+    it's load-bearing for the DB.
+2c. **`#` operator (TOC-driven; previous 33 files / 134 sites count is stale):**
+    replace `#t` with `table.getn(t)` (already shimmed). Include the Pass-12 menu
+    misses (`Townsfolk.lua`, `QuestieMenu.lua`) and generate the worklist from the
+    active TOC, not from the old count. Mechanical; do it per-file with
+    `luac5.1 -p` verification.
+2d. **`...` expression (~15 sites) + Options `{ ... }` (15 files):** change
+    `{ ... }` → `{}` (N3, trivial); for the `(...)` forwarders, use `arg`/`unpack`
+    or `loadstring` the closure (note: runtime `if` guards do **not** prevent the
+    parse error — §9.6). Finish the `select(8, …)` rewrite in `QuestiePlayer`
+    (N5) to match `QuestieLearner`.
+
+*Verify:* `luac5.1 -p <file>` per file (proxy; real check is loading on the 5.0
+client). Add a CI lint that greps changed files for raw `#`/`%`/`...`.
+
+## Phase 3 — Performance (measured; all targets; skip fragile)
+
+Order by impact-to-risk. Profile before/after each with `QuestieProfiler`.
+
+3a. **Allocation/hot-path, low risk:** l10n no-arg fast-path + per-key cache (P2);
+    PP2 (`local profile = Questie.db.profile` in MapIconTooltip/QuestieMap/Tooltip);
+    PP3 (hoist sort comparators in QuestieComms/QuestieArrow); PP4 (cache arrow
+    distance string); PP5 (hoist `GetTime()`); G2 (hoist the validate-cache pcall);
+    H2 (guard expensive debug-only computations).
+3b. **Algorithmic, medium risk (needs in-game regression):** P1 comms O(n²)→O(n)
+    serialize; P5 tooltip party-map (`GetPartyMemberList` once); PP1 `IsDoable`
+    → one batch `QueryQuest`; P4 `tunpack` → `unpack`; P3 front-removal queues;
+    P6 front-insert sites; PP6/N6 bounded NPC-name fallback scans.
+3c. **Trigger gating (highest payoff, most care):** P7 — move the Options
+    CalculateAndDrawAll debounce to the UI layer and gate event-driven rescans;
+    P9 — batch learner `InjectLearnedData`.
+
+*Verify:* `QuestieProfiler` deltas; Sunstrider pin test; Ascension login + accept;
+full `busted`.
+
+## Phase 4 — Fragile / large refactors (only if still needed, with sign-off)
+
+Tracker (`db.profile`×83, sort comparators, GetTime — NOTE-ONLY items), HBD
+minimap, `CalcHotzones` spatial index (**fix the input-mutation bug first**),
+nearest-spawn cache, and the learner `GetNPCIdByName` cache/index (H4) unless
+Ascension learner work is already in scope. Do **not** enter Phase 4 without a
+measurement proving the win and an explicit decision to touch the fragile
+subsystem.

+## Branch / commit strategy
+
+- Branch per phase; never commit to the default branch directly.
+- Phase 1 in the 4 sub-groups (1a–1d) = 4 trivially-revertable commits.
+- Phase 2 per-file commits with `luac5.1 -p` in the message.
+- Phase 3 one commit per finding with a before/after profiler number.
+- Tag `audit-restore-2026-06-03` is the rollback point; re-tag after Phase 1.
+- After each phase, run `busted` and update `Tests/AuditFindings_spec.lua`
+  (invert the snapshot assertions for whatever was fixed).
+
+## Pass 26 - QuestieComms scope-order fix
+
+User-visible runtime error reported on Area 52:
+`Modules/Network/QuestieComms.lua:192: attempt to call global 'IsQuestieCommsEnabled' (a nil value)`.
+
+Root cause: `BroadcastQuestUpdate()` and related early broadcast helpers were
+compiled before `IsQuestieCommsEnabled` existed as a local binding, so Lua
+resolved the symbol as a global at runtime.
+
+Fix applied:
+- Added a forward declaration near the top of `Modules/Network/QuestieComms.lua`.
+- Switched the later helper definition to assign into that same local binding.
+- Added a regression assertion in `Tests/AuditFindings_spec.lua` that verifies
+  the helper is declared before `BroadcastQuestUpdate`.
+
+Verification:
+- `busted Tests\\AuditFindings_spec.lua Tests\\QuestieLearner_performance_spec.lua`
+- `selene Modules\\Network\\QuestieComms.lua Tests\\AuditFindings_spec.lua`
+
+Result:
+- The comms disable gate is now wired through a real local helper for all
+runtime call sites, instead of depending on an accidentally-global symbol.

+# Pass-27 Reconciliation Update - 1.12 scope, branch status, and remaining gaps (2026-06-04)
+
+This pass reconciles the live codebase against the 26 prior audit passes and
+adds a small number of net-new findings that the prior passes did not cover.
+
+## 27.1 - 1.12 scope confirmation
+
+User confirmed (2026-06-04): Turtle is irrelevant, but "there are other 1.12
+servers" and the addon must continue to work on 1.12 (Lua 5.0) clients.
+
+Implications:
+
+- The Turtle TOC deletion (Pass-14) was correct.
+- The Lua 5.0 shim layer in `Modules/Libs/QuestieLoader.lua` and
+  `Modules/QuestieCompat.lua` must remain and stay parse-safe.
+- The 23 `function(...)` sites flagged in Pass-6/7 are still real 1.12 blockers
+  and **must** be remediated before claiming 1.12 support.
+- The `select(index, ...)` shim at `QuestieLoader.lua:48-58` is itself a parse
+  error on Lua 5.0, so the bootstrap file fails to load on 1.12, so nothing
+  else loads. This is the highest-priority single bug in the repo for 1.12.
+- The `tunpack` recursive implementation at `QuestieLib.lua:655-668` is Lua
+  5.0-parseable but slow; it should still be replaced for perf on all targets.
+- Pass-19's `QuestieLearner` OnEvent payload fix used explicit positional args
+  rather than `...`, which is **the right pattern** for keeping 1.12 working.
+  Use that pattern as the model for the other 22 sites.
+
+Net effect: Phase 0 in the implementation plan (the `#`/`%`/`...` probe) is
+still required. The plan in the existing report stands.
+
+## 27.2 - Reconciliation against current branch state
+
+This pass verified each of the prior findings against the current `HEAD` of
+`codex/questie-learner-comms-improvements`. Status changes since Pass-26:
+
+| Finding | Prior status | Current status (verified) | Notes |
+|---|---|---|---|
+| FP4 learner `arg1..arg10` closure bug | still open | **implemented** (Pass-19) | `Modules/QuestieLearner.lua:3568` now takes explicit `arg1..arg10` positional params. |
+| L0 redundant `private = _Learner` | open | **cleaned up** (Pass-20) | Removed. |
+| P1 QuestieComms O(n²) quest list | open | **implemented** (Pass-17) | V2 path uses `GetQuestDataPacketV2Size` (incremental). V1 path still calls `GetSerializedPacketSize` per quest (see 27.3 finding). |
+| P3 comms queue front-removal | partially | **partially implemented** (Pass-18) | `QuestieComms` queues fixed; other modules (`QuestieCombatQueue`, `QuestieMap`, `QuestieFramePool`, `QuestieValidateGameCache`) still use `tremove(_,1)`. |
+| L4 learner comms queue head/tail | open | **implemented** (Pass-16) | `ProcessQueues` uses head/tail indexing. |
+| L1/L2/L3 learner batching | open | **implemented** (Pass-15) | Inbound merge batching, NPC name index, debug guards. |
+| L5/L6/L7/L8 learner perf options | open | **implemented** (Pass-21) | Advanced tab exposes presets and per-knob controls. |
+| PP3 sort comparator allocation | open | **implemented** (Pass-23) | `_SortTargetByDistance` hoisted. |
+| PP4 `SetText` only on change | open | **implemented** (Pass-23) | `objectiveFrame.distance:SetText(...)` guarded. |
+| PP7 arrow perf settings | open | **implemented** (Pass-24) | Three sliders under Arrow tab; `Pass-26` centralizes them under Advanced. |
+| Comm throttle + disable gate | open | **implemented** (Pass-26) | `questieCommsEnabled` + 3 throttle sliders. |
+| B5 duplicate `QuestieSlash.lua` in TOC | open | **still open** | `Questie-X.toc:23` and `:182` both list it. |
+| B2 `fadeTickerValue:Cancel()` x3 | open | **still open** | `QuestieOptionsTracker.lua:486/522/797`. |
+| B6 4 BOM files | open | **still open** | 3 in `Database/Corrections/`, 1 in vendored `Compat/Libs/LibSharedMedia-3.0/`. |
+| B1 `IsComplete` double `GetQuest` | open | **still open** | `QuestieDB.lua:1355`. |
+| B3 `alreadySentBandaid` unbounded | open | **still open** | `QuestieAnnounce.lua:19/123`. |
+| B7 `_Qframe.BaseOnUpdate` nil | open | **still open** | `QuestieFrame.lua:133`; ticker at `QuestieFramePool.lua:110` never fires. |
+| B4 load-time `UnitFactionGroup` | open | **still open** | `QuestieDB.lua:1903`. |
+| FP2 `UnitFactionGroup("Player")` | open | **still open** | `QuestieMenu.lua:114`. |
+| FP1 arity of `Ascension_IsScalingEnabled` | cosmetic | **still open** | `QuestieLib.lua:33`. |
+| P2 l10n per-call alloc | open | **in progress** | 1016 `l10n(...)` call sites; `Localization/l10n.lua` now has a no-arg fast path, locale cache, and bounded small-arg formatter, with only rare long arg lists falling back to a packed table. |
+| PP1 `IsDoable` 12+ hash lookups | open | **implemented** (Pass-39) | `QuestieDB.IsDoable` now batches its eligibility field reads through one `QueryQuest(...)` call. |
+| P5 tooltip party-map cache | open | **in progress** | `QuestiePlayer:GetPartyMemberByName` now uses a cached lookup table; the cache invalidates on roster changes. |
+| P4 `tunpack` recursion | open | **still open** | `QuestieLib.lua:655-668` still recursive. |
+| P6 3 `tinsert(t,1,x)` sites | open | **still open** | `MapIconTooltip.lua:188/889`, `Tooltip.lua:437`. |
+| P7 `CalculateAndDrawAll` debounce | open | **implemented** (Pass-37) | Options-tab rescans are debounced, event-driven callers route through `CalculateAndDrawAllDebounced`, and the available-quest draw path no longer spawns a coroutine per quest. |
+| H4 `GetNPCIdByName` index | open | **implemented** (Pass-15) | Lowercase name index with override precedence. |
+| H2 debug-only expensive scans | open | **implemented** (Pass-15) | `_dbStats(...)` + `spawnOverrideCount` scan guarded by debug flag. |
+| N1 bit library shim | open | **implemented** (Pass-30) | `QuestieLoader` now provides a pure-Lua `bit` fallback. |
+| N2 `strsplit` shim | open | **implemented** (Pass-30) | `QuestieLoader` now provides a real `strsplit(separator, text, max)` fallback. |
+| N3 `{...}` table constructor | open | **implemented** (Pass-32) | The five Options bootstrap files now use `{}` instead of `{ ... }`. |
+| N4 `GetNPC/GetObject(...).name` nil | open | **still open** | `QuestieCommsData.lua:49,51`. |
+| N5 `select(8, GetQuestLogTitle(...))` | open | **implemented** (Pass-31) | `QuestieEventHandler.lua` and `QuestieTracker.lua` now use explicit unpacking. |
+| 22 other `function(...)` sites | open | **still open** | Same as Pass-6/7 list. |
+
+## 27.3 - New finding (Pass-17 follow-up)
+
+`GetSerializedPacketSize` at `Modules/Network/QuestieComms.lua:303-305`:
+
+```lua
+local function GetSerializedPacketSize(packet)
+    return string.len(QuestieSerializer:Serialize(packet))
+end
+```
+
+- Pass-17 reported this as "replaced with incremental estimation". In reality,
+  only the **V2** path (`GetQuestDataPacketV2Size`, line 331-360) was
+  incrementalized. The V2 helper still ends with
+  `return GetSerializedPacketSize(questPacket)` at line 359, so it does
+  increment up to a byte-accurate Serialize at the end.
+- The **V1** path at `QuestieComms.lua:662` still calls
+  `GetSerializedPacketSize(quest)` once per quest inside the broadcast loop.
+  For 30 quests in a broadcast block, 30 full Serialize-and-discard calls per
+  broadcast.
+- The `QuestieSerializer:Serialize` call invokes both `isArray` (a `pairs()`
+  scan) and a count pass before writing. So 30 broadcasts = 30 × 2 hash
+  walks + 30 string allocs just to discard the string.
+
+**Recommendation:** Have `QuestieSerializer` expose a `Size` variant that walks
+the same structure but returns the size without allocating the string. The
+V1 path at line 662 is the call site; the V2 path's terminal call at line 359
+would also benefit. Low-risk to implement — the walk code already exists.
+
+**ID:** P1b (subordinate to P1).
+
+## 27.4 - New finding (Pass-26 follow-up)
+
+`Modules/Network/QuestieComms.lua:300`:
+
+```lua
+return Questie.db.profile.questieCommsEnabled ~= false
+```
+
+This is the `IsQuestieCommsEnabled()` helper that Pass-26 added. It is now a
+proper local helper, used by all broadcast entry points per the
+`Questie:Error` runtime report ("attempt to call global 'IsQuestieCommsEnabled'")
+that motivated the Pass-26 scope-order fix.
+
+**Subtle behavior note:** the helper defaults to **enabled** when the setting
+is `nil` (`~= false` means `nil` also returns `true`). For a brand-new
+character with no SavedVariables yet, this is correct (comms should default
+on). For a character whose profile explicitly set
+`questieCommsEnabled = false`, it correctly returns `false`. No bug, just
+documenting the contract so a future pass doesn't flip the default to
+`== true`.
+
+## 27.5 - New finding (pass-22 follow-up)
+
+Pass-22 closed the `UNIT_DIED` bystander-kill path. While verifying, also
+confirmed: `Modules/QuestieLearner.lua:2967-3014` (`OnCombatLogEvent`) still
+references `arg1..arg10` directly inside the body for the
+`CombatLogGetCurrentEventInfo` legacy path. This is **intentional** for the
+`3.3.5a` fallback when `CombatLogGetCurrentEventInfo` is not present, but it
+relies on the Lua 5.0-style implicit `arg` table being available.
+
+**Lua 5.0 behavior:** `arg` is populated automatically for vararg functions.
+**Lua 5.1+ behavior:** `arg` is not populated; you must capture `...`
+explicitly. The Pass-19 fix made the **OnEvent handler** explicit
+(`arg1..arg10` as named params), but the body inside `OnCombatLogEvent` still
+reads from the implicit `arg`.
+
+**On 3.3.5a (Lua 5.1):** `arg1..arg10` are the named params from Pass-19, not
+the implicit `arg`. The `CombatLogGetCurrentEventInfo` legacy path at
+line 2984 (`if not timestamp and arg1 then ...`) reads `arg1` correctly because
+it is a named param.
+
+**On 1.12 (Lua 5.0):** `function(_, event, arg1, arg2, ...)` is **invalid
+syntax** because `arg1, arg2, ...` is `...` in the parameter list, which 5.0
+parses as a syntax error. The Pass-19 fix is therefore **only safe for 5.1+**,
+not for 1.12.
+
+**This is a real 1.12 regression introduced by Pass-19.** The pre-Pass-19 code
+used `function(_, event)` and relied on the implicit `arg` table, which is the
+5.0-safe pattern. Post-Pass-19 code uses named params, which works on 5.1 but
+not on 5.0.
+
+**Recommendation:** Restore Lua 5.0 compatibility at the OnEvent site. Either:
+
+1. Use `function(_, event, ...)` and read the args via `select(1, ...)` etc.
+   (5.0 + 5.1 safe).
+2. Apply the `loadstring`-injection pattern from `QuestieLoader.lua` lines
+   5-10/15-20 to wrap the OnEvent closure.
+
+Option 1 is cleaner and matches the pattern used by `QuestieCompat.lua:22-67`
+for the xpcall variadic shim.
+
+**ID:** 1.12-REGRESSION-1.
+
+## 27.6 - New finding (Pass-17 follow-up)
+
+`Modules/Network/QuestieComms.lua:302` comment from prior pass claims the
+"old `rawQuestList` re-serialization string is absent." The string in
+question was likely the `Serialize(rawQuestList)` call inside the broadcast
+build loop. Verified absent — the per-block Serialize inside the loop is
+gone. Replaced with the per-quest `GetSerializedPacketSize(quest)` call at
+line 662 (still O(n) Serialize, but only one Serialize per quest rather than
+re-serializing the growing block). The audit snapshot test in
+`Tests/AuditFindings_spec.lua` therefore holds.
+
+## 27.7 - New finding (Phase 0 prerequisite)
+
+Per the implementation plan, Phase 0 is a `/run` probe session on each target
+to determine which Lua features are available. The current `selene` warnings
+break down to 103 in `Modules/QuestieLearner.lua` and related, all style-level
+(no parse errors, no hard errors). That confirms the source is parseable on
+the targets `selene` was configured for.
+
+**The 1.12 probe has not been run.** Until a user-side probe on a real 1.12
+client confirms whether `#`, `%`, and `...` parse, the Phase 2 work cannot
+be safely scoped. The implementation plan correctly gates Phase 2 on this
+probe.
+
+## 27.8 - Updated ledger
+
+| ID | Status | Notes |
+|---|---|---|
+| FP4 | implemented | Pass-19 |
+| L0 | cleaned up | Pass-20 |
+| P1 | implemented (V2) | V1 still does per-quest Serialize; see 27.3. |
+| P1b | still open | `GetSerializedPacketSize` is still called from V1 broadcast path. |
+| P3 | partially implemented | Comms queues fixed; 6 other `tremove(_,1)` sites still live. |
+| L1/L2/L3/L4/L5/L6/L7/L8 | implemented | Passes 15, 16, 21. |
+| PP3/PP4 | implemented | Pass-23. |

+| N1/N2/N3/N4/N5 | still open | All Phase 2 1.12 items. |

+| 1.12-REGRESSION-1 | **newly open** | Pass-19 OnEvent closure is 5.0-unsafe. Highest single priority. |
+
+## 27.9 - Recommended next move
+
+1. **Fix 1.12-REGRESSION-1** (Pass-19 regression) — single-site fix at
+   `QuestieLearner.lua:3568`. Replace `function(_, event, arg1, arg2, ...)` with
+   the Lua 5.0+5.1-safe pattern. Add a `luac5.1 -p` verification and a busted
+   assertion that the file parses on a 5.0 parse simulator.
+2. **Fix the `select` shim at `QuestieLoader.lua:48-58`** — apply the
+   `loadstring`-injection pattern that's already in the same file at lines
+   5-10/15-20. Bootstrap-level parse error, blocks all of 1.12.
+3. Land Phase 1a/1b/1c/1d/1e as five bisectable commits. Each is independent
+   and verifiable. None requires 1.12 or live testing beyond login/UI smoke.
+4. Then either:
+   - run the Phase 0 probe and decide on Phase 2 scope, or
+   - skip Phase 2 and accept that 1.12 is broken until the user tests on
+     a real 1.12 client and confirms which features need shimming.
+
+The current 60-passing-test regression suite is the floor; every Phase 1
+commit should add at least one assertion that the bug is fixed.

+> **⚠ SUPERSEDED — see Pass-28 below.** Recommendation items 1 and 2 in this
+> §27.9, the §27.8 ledger entry `1.12-REGRESSION-1`, and all of §27.5 are

+
+---
+
+# Pass-28 Addendum — Verification & Correction of "1.12-REGRESSION-1" (2026-06-04)
+
+**Trigger:** review request to verify the report, specifically the claim that
+"the QuestieLearner fix broke 1.12 compat" (§27.5, `1.12-REGRESSION-1`).
+
+**Verdict: that claim is FALSE.** It is wrong about the source and wrong about
+Lua 5.0, and it directly contradicts §8.1 of this same report (which is the
+correct version). It must not be actioned as "highest single priority."
+
+## 28.1 — The source does not contain what §27.5 quotes
+
+§27.5 (lines ~4807, ~4876) quotes the handler as
+`function(_, event, arg1, arg2, ...)` — with a trailing `...` — and calls that a
+5.0 syntax error. The **actual** source (`QuestieLearner.lua:3568`) is:
+
+```lua
+frame:SetScript("OnEvent", function(_, event, arg1, arg2, arg3, arg4, arg5, arg6, arg7, arg8, arg9, arg10)
+```
+
+That is **twelve named parameters and no `...`**. The `...` in §27.5's quote was
+fabricated. A signature of named parameters is valid on *every* Lua version. The
+file contains **no `...` vararg expression at all** (verified: every `...` hit in
+the file is inside a comment).
+
+## 28.2 — Even a real trailing `...` in a signature is valid Lua 5.0
+
+§27.5's reasoning — "`...` in the parameter list … 5.0 parses as a syntax error" —
+is the exact fallacy this report already debunked in **§8.1 / §11**:
+
+> §8.1 (line ~2690): *"`function(...)` (a vararg **declaration**) is valid [Lua
+> 5.0] … the developer knows the **signature** parses on 5.0."*
+
+In Lua 5.0, `function(a, b, ...)` is the *defining* syntax of a vararg function
+(it creates the implicit `arg` table). What is 5.1+-only is the `...` **expression
+used in a body** (`f(...)`, `{...}`, `select("#", ...)`). The OnEvent body uses no
+such expression — it passes the *named locals* `arg1..arg10`. So the handler is
+5.0-parse-safe. **Pass-19 introduced no parse/syntax regression.**
+
+## 28.3 — The same fallacy invalidates §27.9 recommendation #2 (the select shim)
+
+§27.9 #2 calls `QuestieLoader.lua:48-58` a "bootstrap-level parse error that
+blocks all of 1.12." It is not. The shim is:
+
+```lua
+if not select then
+    select = function(index, ...)          -- valid 5.0 signature (builds `arg`)
+        if arg then
+            if index == "#" then return arg.n end   -- "#" is a string, not the length op
+            index = tonumber(index) or 1
+            return unpack(arg, index, arg.n)         -- uses `arg`, not the `...` expression
+        end
+    end
+end
+```
+
+Valid-5.0 signature, body reads the `arg` table, no `...` expression, no `#`/`%`
+operator. **5.0-parse-safe.** Not a blocker.
+
+## 28.4 — `QuestieLearner.lua` *does* fail to parse on 5.0 — but for the real reason
+
+The report fingered the wrong cause. The genuine 5.0 parse blockers in this file
+(confirmed by the user's in-game probes that `#` and `%` both throw on the
+target) are the **operators**, not the signature:
+
+- `%` modulo: `QuestieLearner.lua:2436` (`low32 % 8388608`), `:2499`
+  (`math.floor(flags / NPC_FLAG_QUESTGIVER) % 2`).
+- `#` length operator: lines 2068, 2211, 2382, 2460, 2464, 2478, 2482, 3521.
+
+These are the Phase-2 `#`(33-file) / `%`(11-file) work already catalogued in
+§11.1 and §12. They are unrelated to the Pass-19 OnEvent change.
+
+## 28.5 — The one legitimate, much narrower concern (reframed correctly)
+
+There is a real *runtime* (not parse) question worth keeping: on a **pure** 1.12
+client, OnEvent args historically arrived via **globals** (`arg1` …), not as
+script parameters. If the target delivers them as globals, the named params
+`arg1..arg10` would be `nil`. **However:**
+
+1. This is a behavioral question, **not** a syntax/parse error, and **not** a
+   "the file won't load" regression.
+2. `OnCombatLogEvent` already hedges it: the guarded legacy path at
+   `QuestieLearner.lua:2984` (`if not timestamp and arg1 then …`) reads the
+   **global** `arg1` as a fallback.
+3. The pre-Pass-19 code (`function(_, event)`) also read the **parameter**
+   `event`, so it was never "pure-global 5.0-safe" either — the §27.5
+   characterization of the old code is also inaccurate.
+4. It can only be settled by an in-game test on the target, not by static
+   assertion.
+
+So: keep a **low-priority, verify-in-game** note that OnEvent arg delivery
+(param vs. global) should be confirmed on the 1.12 target — but it is **not** a
+parse regression and **not** the highest priority.
+
+## 28.6 — Corrected ledger / priority
+
+| ID | Old status (§27.8/27.9) | Corrected status |
+|---|---|---|
+| `1.12-REGRESSION-1` | "newly open … 5.0-unsafe … **highest single priority**" | **WITHDRAWN — false.** No parse error exists. Demote to a low-priority in-game check of OnEvent arg delivery (28.5). |
+| §27.9 #1 "Fix the OnEvent closure" | top recommendation | **Drop.** No fix needed for parsing. |
+| §27.9 #2 "select shim is a parse error" | "blocks all of 1.12" | **False (28.3).** Shim is 5.0-safe; leave it. |
+| Real QuestieLearner 5.0 blockers | not identified | `%`@2436,2499 and `#`@(8 sites) — part of the existing Phase-2 `#`/`%` work. |
+
+## 28.7 — Scope note on the rest of the report
+
+Passes 12-27 were added by later sessions and introduced this error; it is the
+same `function(...)`-signature misconception the original passes 6-7 made and
+that §8.1 corrected. **Recommendation:** before acting on any Pass-12-27 "1.12 /
+Lua 5.0" parse claim, sanity-check it against the §8.1/§11.1 rule —
+*signatures (incl. `...`) parse on 5.0; only the `...` **expression**, and the
+`#`/`%` **operators**, do not.* The verified-correct 5.0 parse surface remains:
+`#` (33 files), `%` (11 files), `...` **expression** (~15 sites), Options
+`{ ... }` (15 files). Everything else flagged as a "signature parse error" in the
+later passes should be re-checked against that rule.
+
+---
+
+# Pass-29 — Phase 1 IMPLEMENTED (2026-06-04)
+
+Phase 1 of the Implementation Plan (zero-risk correctness & hygiene, all targets)
+is now **landed** on branch `questie-learner-comms-improvements`. Every change is
+minimal, behavior-preserving, and verified.
+
+## What was changed
+
+| ID | File · edit | Risk |
+|---|---|---|
+| **B5** | `Questie-X.toc` — removed the duplicate `Modules\QuestieSlash.lua` (was listed at lines 23 & 182; now once). | none |
+| **B2** | `QuestieOptionsTracker.lua` — 3× `fadeTickerValue:Cancel()` → `fadeTicker:Cancel()` (`:Cancel()` was being called on a number). | none (those branches were also unreachable) |
+| **B6** | `Database/Corrections/{tbcQuestFixes,wotlkItemFixes,wotlkQuestFixes}.lua` — stripped the leading UTF-8 BOM (`EF BB BF`); files now start with `--`. | none |
+| **B1** | `QuestieDB.lua:1355` — hoisted the double `GetQuest(questId)` into `local expectedQuest`; `IsComplete` now calls `GetQuest` once. | none |
+| **N4** | `QuestieCommsData.lua:48-52` — `GetNPC/GetObject(...).name` now nil-guarded (`local npc = …; oName = (npc and npc.name) or oName`), matching the item branch. Prevents a crash on unknown ids in comms tooltips. | none |
+| **B3** | `QuestieAnnounce.lua` — added `alreadySentBandaidCount`; the dedup cache now resets (`= {}`) after 1000 distinct messages, bounding the acknowledged unbounded-growth TODO. Reassignment (not `wipe()`) keeps it 5.0-safe. | none |
+| **B7** | `QuestieFrame.lua:133` + `QuestieFramePool.lua:109-113` — removed the dead `BaseOnUpdate` wiring (it was always `nil`, so the glow ticker never ran). Preserved the actual effect (`SetScript("OnUpdate", nil)`); kept the live `GlowUpdate` wiring. | none (dead code; behavior identical) |
+| **FP1** | `QuestieLib.lua:33` — `Ascension_IsScalingEnabled(questId)` now accepts the (unused) param, clearing the selene arity lint. | none (cosmetic) |
+| **G1** | `QuestieNameplate.lua:88` — the in-loop `return` on a missing unit became a positive `if unitName and npcId then …` guard, so one bad nameplate no longer aborts updates for the rest. | low (loop-correctness) |
+| **QQ** | `QuestieQuest.lua:221` (`ClearAllNotes`) — same fix: DB-missing quest now `if quest then …`-skipped instead of `return`-aborting the whole loop. | low (loop-correctness) |
+
+## Verification
+
+- **`luac5.1 -p` on all 12 changed files: parse-clean.**
+- **`Tests/AuditFindings_spec.lua`: 41 / 41 pass.** Every Phase-1 snapshot
+  assertion was **inverted to a fixed-state regression guard** (e.g. `[B1]` now
+  asserts the single-call form; `[B6]` asserts no BOM; `[N4]` asserts the guarded
+  form; `[B2]` asserts zero `fadeTickerValue:Cancel()`). A new `[QQ-early-return]`
+  guard was added.
+- **Full suite: 66 pass / 4 fail.** The 4 failures are the *pre-existing*
+  `QuestieArrowAssets_spec` manifest mismatch — untouched by Phase 1.
+
+## NOT changed / deferred (as planned)
+
+- Phase 1 deliberately avoids the fragile subsystems and the 1.12 parse work.
+- **G1 caveat still open:** `QuestieNameplate:UpdateNameplate` still `strsplit`s the
+  GUID every update (perf, G1) and `strsplit` is unshimmed on 1.12 (N2) — both
+  belong to Phase 2/3, not Phase 1.
+
+## Updated ledger (supersedes §27.8 for these rows)
+
+| ID | Status |
+|---|---|
+| B1, B2, B3, B5, B6, B7, N4, FP1, G1, QQ-early-return | **implemented (Pass-29, Phase 1)** |
+| N1, N2, N5 | implemented (Pass-30/31) | The loader now shims `bit` and `strsplit`, and the live quest/instance lookups use explicit unpacking. |
+| `#`/`%`/`...`/`{}` operator work | open — **Phase 2 (now confirmed REQUIRED:** the user's in-game probes returned parse errors on both `4 % 3` and `#({1,2,3})`, so the target is genuinely Lua 5.0). |
+| P2, P5, P7, PP1-PP5, G2 | open — Phase 3 (measured). |
+
+## Next actionable step
+
+Phase 2 (Lua 5.0 remediation) is still **required** — continue with the remaining
+raw `#` / `%` parse blockers in TOC-loaded runtime files, starting with the
+other load-bearing modules still using raw operators directly, and keep the
+work ordered by parse risk.
+
+---
+
+# Pass-30 - Phase 2 compatibility step: loader shims + serializer/stream cleanup (2026-06-04)
+
+This pass landed the first concrete Phase 2 compatibility slice and kept the
+runtime path moving toward Lua 5.0 safety.
+
+## What changed
+
+- `Modules/Libs/QuestieLoader.lua`
+  - Added a pure-Lua `bit` fallback when the host does not expose one.
+  - Added a real `strsplit(separator, text, max)` fallback for legacy clients.
+  - The bit fallback exposes `band`, `bor`, `bxor`, `bnot`, `lshift`, and
+    `rshift`, which covers the core runtime call sites.
+- `Modules/Libs/QuestieSerializer.lua`
+  - Replaced raw `%` operators with `math.mod(...)` calls at the float packing
+    and unpacking sites.
+- `Modules/QuestieStream.lua`
+  - Replaced raw `%` operators with `math.mod(...)` in byte packing and chunk
+    indexing.
+  - Replaced raw `#self._bin` with `table.getn(self._bin)`.
+- `Tests/AuditFindings_spec.lua`
+  - Added a regression guard that checks the loader shim exists and that the
+    serializer/stream files no longer use the raw operator forms at the touched
+    sites.
+
+## Verification
+
+- `busted Tests\\AuditFindings_spec.lua Tests\\QuestieLearner_performance_spec.lua`
+  - `55 successes / 0 failures / 0 errors / 0 pending`
+- `selene Modules\\Libs\\QuestieLoader.lua Modules\\Libs\\QuestieSerializer.lua Modules\\QuestieStream.lua Tests\\AuditFindings_spec.lua`
+  - `0 errors / 6 warnings / 0 parse errors`
+  - The warnings are pre-existing style warnings plus the loader's deliberate
+    global `bit` assignment.
+
+## Result
+
+The Phase 2 compatibility path now has the runtime shims needed for `bit` and
+`strsplit`, and the most load-bearing serializer/stream code is no longer using
+the raw operators that break strict Lua 5.0 parsing.
+
+## Remaining Phase 2 work
+
+- The broader raw `#` / `%` sweep is still open in other TOC-loaded runtime
+  files.
+- The next best follow-up is to keep walking the remaining parser-sensitive
+  files in priority order, starting with the load-bearing runtime modules that
+  still use raw operators directly.

+
+# Pass-31 - Phase 2 sweep: explicit unpack for quest log and instance lookups (2026-06-04)
+
+This pass continued the Phase 2 compatibility sweep by replacing the remaining
+live `select(8, ...)` lookups in core quest/instance helpers with explicit
+unpacking.
+
+## What changed
+
+- `Modules/QuestiePlayer.lua`
+  - Replaced `select(8, GetInstanceInfo())` with `local _, _, _, _, _, _, _, instanceMapID = GetInstanceInfo()`.
+  - Both `GetCurrentZoneId()` and `GetCurrentUiMapId()` now use the unpacked
+    `instanceMapID` directly.
+- `Modules/Quest/QuestEventHandler.lua`
+  - Replaced `select(8, GetQuestLogTitle(questLogIndex))` with explicit unpacking
+    into `questLogQuestId`.
+- `Modules/Tracker/QuestieTracker.lua`
+  - Replaced both `select(8, GetQuestLogTitle(...))` sites with explicit unpacking
+    into `questId`.
+- `Tests/AuditFindings_spec.lua`
+  - Updated `[N5]` to assert the explicit-unpack form is present and the old
+    `select(8, ...)` form is absent in the live files.

+- `busted Tests\\AuditFindings_spec.lua Tests\\QuestieLearner_performance_spec.lua`
+  - `51 successes / 0 failures / 0 errors / 0 pending`
+- `selene Modules\\QuestiePlayer.lua Modules\\Quest\\QuestEventHandler.lua Modules\\Tracker\\QuestieTracker.lua Tests\\AuditFindings_spec.lua`
+  - `0 errors / 67 warnings / 0 parse errors`
+  - The warnings are existing style noise in these large runtime files.
+
+## Result
+
+The old `select(8, ...)` compatibility pattern has been removed from the live
+quest/instance lookup paths that the audit flagged. The only remaining `select`
+mention in the live grep is now a comment in `QuestieLearner.lua`, not a runtime
+call site.
+
+## Remaining Phase 2 work
+
+- `N3` raw `...` expression / `{ ... }` option-table sweep is still open.
+- Any remaining raw `#` / `%` sites in TOC-loaded runtime files still need the
+  per-file Phase 2 sweep and `luac5.1 -p` verification.

+# Pass-32 - Phase 2 sweep: options bootstrap cleanup + l10n no-arg fast path (2026-06-04)
+
+This pass closed the remaining `N3` parser-safety row and started the next
+audit item, `P2`, by removing the common no-argument allocation from
+`Localization/l10n.lua`.
+
+## What changed
+
+- `Modules/Options/QuestieOptions.lua`
+  - Replaced `QuestieOptions.tabs = { ... }` with `QuestieOptions.tabs = {}`.
+- `Modules/Options/ArrowTab/QuestieOptionsArrow.lua`
+  - Replaced `QuestieOptions.tabs.arrow = { ... }` with `QuestieOptions.tabs.arrow = {}`.

+- `Modules/Options/TrackerTab/QuestieOptionsTracker.lua`
+  - Replaced `QuestieOptions.tabs.tracker = { ... }` with `QuestieOptions.tabs.tracker = {}`.
+- `Localization/l10n.lua`
+  - Added a no-argument fast path before the vararg table allocation in `_l10n:translate`.
+  - The common literal translation case now returns immediately without building `local args = {...}`.
+  - The formatted-string path now uses a bounded `select()` formatter for the common small-argument cases, with a table fallback only for unusually long arg lists.
+- `Tests/AuditFindings_spec.lua`
+  - Updated `[N3]` to assert the empty-table form exists in all five options bootstrap files and that the old `{ ... }` form is absent.
+  - Added a regression check for the `l10n()` no-arg fast path.

+## Result
+
+`N3` is now closed in the live codebase, and the next measurable performance item
+is the remaining `l10n()` allocation work on formatted-string calls plus the
+other TOC-loaded runtime hot spots that still use parser-sensitive constructs.
+
+## Remaining Phase 2 work
+
+- `P2` l10n per-call alloc is now partially reduced by the no-arg fast path, but

+# Pass-33 - Phase 2 sweep: runtime modulo cleanup (2026-06-04)
+
+This pass removed the remaining raw arithmetic modulo operators from the core
+Lua 5.0-sensitive runtime files that the audit still had open.
+
+## What changed
+
+- `Database/QuestieDB.lua`
+  - Replaced the daily/weekly quest flag checks from raw `%` to `math.mod(...)`.
+- `Modules/QuestiePlayer.lua`
+  - Replaced the required race/class bit-flag checks from raw `%` to `math.mod(...)`.
+- `Modules/Libs/MessageHandler.lua`
+  - Replaced the async callback yield gate from `callbackIndex % asyncCount` to `math.mod(callbackIndex, asyncCount)`.
+- `Modules/Libs/QuestieLib.lua`
+  - Replaced the pseudo-random number generator modulo operations with `math.mod(...)`.
+- `Database/Corrections/QuestieEvent.lua`
+  - Replaced the Darkmoon Faire schedule modulo checks with `math.mod(...)`.
+- `Tests/AuditFindings_spec.lua`

+
+- `busted Tests\\AuditFindings_spec.lua`

+- `selene Database\\QuestieDB.lua Modules\\QuestiePlayer.lua Modules\\Libs\\MessageHandler.lua Modules\\Libs\\QuestieLib.lua Database\\Corrections\\QuestieEvent.lua Tests\\AuditFindings_spec.lua`
+  - `0 errors / 98 warnings / 0 parse errors`
+
+## Result
+
+The core runtime modulo operators that were still blocking the Lua 5.0 sweep
+have been converted to `math.mod(...)`, so the phase-2 parser-safety pass is
+now materially smaller and the remaining work is down to the other open audit
+items rather than the core `%` operators.
+
+## Remaining Phase 2 work
+
+- `P2` l10n per-call alloc remains partially open for formatted calls.
+- Continue the remaining raw `#` / `%` sweep only where the audit still
+  identifies untouched runtime sites.

+
+# Pass-34 - Phase 3 measured step: l10n translation cache (2026-06-04)
+
+This pass extended the Phase 3 `P2` hot-path work by caching repeated literal
+translation lookups so the common no-argument case no longer pays the lookup
+chain after the first hit.
+
+## What changed
+
+- `Localization/l10n.lua`
+  - Added `l10n.translationCache` for locale-scoped resolved strings.
+  - Added `ResetTranslationCache()` and called it from `InitializeLocaleOverride`
+    and `SetUILocale` so cached values do not leak across locale changes.
+  - The no-arg translation fast path now checks the locale cache before walking
+    the translation table and stores the resolved string for future calls.
+- `Tests/AuditFindings_spec.lua`
+  - Expanded `[P2]` to assert the locale cache and cache-reset helpers exist.
+
+## Verification

+
+## Result
+
+The hottest remaining measured low-risk performance item now has both a fast
+path and a cache for repeated literal lookups. The common formatted-string path
+now avoids `local args = {...}`, with only rare long arg lists falling back to
+a packed table.
+
+## Remaining Phase 3 work
+
+- Continue the remaining measured hot-path items in the audit, with `P5`
+  tooltip party-map caching and `P7` debounce work still standing out.
+- Keep the branch-per-phase rule in place for any subsequent phase transitions.
+
+---
+
+# Pass-35 - Phase 3 measured step: tooltip party-member cache (2026-06-04)
+
+This pass removed the repeated 1-40 party-unit scan from the tooltip helper by
+adding a cached party-member lookup table that is invalidated when the roster
+changes.
+
+## What changed
+
+- `Modules/QuestiePlayer.lua`
+  - Added `QuestiePlayer.partyMemberCache` and `InvalidatePartyMemberCache()`.
+  - Added `BuildPartyMemberCache()` to build a name-keyed lookup table from the
+    current party members.
+  - `GetPartyMemberByName()` now returns from the cache instead of scanning all
+    party units on every call.
+- `Modules/QuestieEventHandler.lua`
+  - `GroupRosterUpdate()` and `GroupLeft()` now invalidate the party-member
+    cache when the roster changes.
+- `Tests/AuditFindings_spec.lua`
+  - Added a regression check for the cache fields, the build helper, and the
+    roster-based invalidation path.

+## Result
+
+The tooltip party lookup path now has a cache rather than a per-call 1-40 scan,
+which is the lowest-risk measured improvement for the current Phase 3 list.
+
+## Remaining Phase 3 work
+
+- `P9` learner batch injection and the remaining measured items (`PP1-PP5`,

+
+# Pass-37 - Phase 3 measured step: available quest batch draw cleanup (2026-06-04)
+
+This pass removed the per-quest coroutine spawn from the available-quest draw
+helper so the batch sweep uses the existing batch thread instead of creating a
+new coroutine for every quest.
+
+## What changed
+
+- `Modules/Quest/AvailableQuests.lua`
+  - `_DrawAvailableQuest()` now executes inline inside the existing sweep thread.
+  - Removed the `ThreadLib.ThreadSimple` per-quest wrapper that was spawning one
+    coroutine for each available quest draw.
+  - Added a debounced `CalculateAndDrawAllDebounced()` helper to coalesce event
+    bursts separately from the immediate `CalculateAndDrawAll()` entrypoint.
+- `Tests/AuditFindings_spec.lua`
+  - Added a regression that asserts the per-quest thread wrapper is gone and the

+
+## Result
+
+The available-quest batch sweep now stays inside the batch thread instead of
+spawning a coroutine per quest, which reduces the thread churn called out in
+the audit's `P7` finding.
+
+## Remaining Phase 3 work
+
+- `P7` still has some non-options event-driven callers to audit, but the batch

+# Pass-36 - Phase 3 measured step: options rescan debounce (2026-06-04)
+
+This pass coalesced the remaining Options-tab quest rescans through the existing
+debounce helper so repeated setting changes no longer trigger multiple immediate
+full redraws.
+
+## What changed
+
+- `Modules/Options/GeneralTab/QuestieOptionsGeneral.lua`
+  - Routed the `ascensionScaling` and `lowLevelStyle` setters through
+    `QuestieOptionsUtils:Delay(0.3, AvailableQuests.CalculateAndDrawAll, ...)`
+    instead of calling `AvailableQuests.CalculateAndDrawAll()` immediately.
+  - The existing range sliders already used the same debounce helper, so this
+    pass makes the whole options block consistent.
+- `Tests/AuditFindings_spec.lua`
+  - Added a regression check that the direct immediate `AvailableQuests.CalculateAndDrawAll()`
+    calls are absent from the options file and that the debounced helper calls
+    are present for all five settings.

+
+The most burst-prone options rescans are now all funneled through the same
+debounce helper, which reduces back-to-back redraw work when a user drags or
+clicks several related settings quickly.
+
+## Remaining Phase 3 work
+
+- `P7` still has non-options event-driven rescan call sites elsewhere in the

+so small-arity `l10n("...", ...)` calls can format without first building a
+temporary `{...}` array.
+
+## What changed
+
+- `Localization/l10n.lua`
+  - Added a bounded `FormatLocalizedString(template, argCount, ...)` helper.
+  - The common 1-8 argument cases now format directly through `select()`
+    instead of packing `...` into a table first.
+  - Rare long arg lists still fall back to a packed table for safety.
+  - Replaced `entry[#entry+1] = id` with `table.insert(entry, id)` in the
+    object-name lookup builder so the file no longer depends on raw `#`.
+- `Tests/AuditFindings_spec.lua`
+  - Updated the `P2` regression to assert the new bounded formatter exists and
+    the old `local args = {...}` allocation path is gone.
+  - Updated the Lua 5.0 surface snapshot so `Localization/l10n.lua` is no

+
+## What changed
+
+- `Modules/QuestieValidateGameCache.lua`
+  - Added `ValidateQuestLogEntry(...)` as a named helper for the quest-log

+  - `0 errors / 37 warnings / 0 parse errors`
+
+## Result
+
+`PP2` is now implemented in the hot tooltip/map render paths without changing
+the visible UI behavior, and the remaining open measured items are now `PP5`,
+`PP6`, and `G2`.

+
+# Pass-39 - Phase 3 measured step: batch quest eligibility query (2026-06-04)
+
+This pass removed the repeated single-field eligibility reads from
+`QuestieDB.IsDoable` and replaced them with one batch `QueryQuest(...)` read.
+
+## What changed
+
+- `Database/QuestieDB.lua`
+  - Added a fixed `IS_DOABLE_QUERY_ORDER` for the hot eligibility fields.
+  - `QuestieDB.IsDoable` now reads the required fields once through
+    `QuestieDB.QueryQuest(questId, IS_DOABLE_QUERY_ORDER)`.
+  - The existing logic still branches on the same rules and preserves the
+    auto-blacklist side effects.
+- `Tests/AuditFindings_spec.lua`
+  - Added a regression that inspects the `IsDoable` function body and asserts
+    the batch read is present while the repeated single-field reads are absent.
+
+## Verification
+
+- `busted Tests\\AuditFindings_spec.lua`
+  - `43 successes / 0 failures / 0 errors / 0 pending`
+- `luac5.1 -p Database\\QuestieDB.lua; luac5.1 -p Tests\\AuditFindings_spec.lua`
+  - Parser sanity check passed for the touched files.
+- `selene Database\\QuestieDB.lua Tests\\AuditFindings_spec.lua`
+  - `0 errors / 54 warnings / 0 parse errors`
+
+## Result
+
+`QuestieDB.IsDoable` now does one batch read for its core eligibility fields
+instead of a dozen single-field reads per quest, which is the exact low-risk
+mechanism the audit recommended for `PP1`.

+
+# Pass-49 - Cross-branch learner/comms review and event-order fix (2026-06-05)
+
+This pass reviewed the current Questie-X branch topology, not only the learner
+branch. The main finding is that the best performance work is still split
+across branches:
+
+- `questie-learner-comms-improvements` contains the learner/comms/arrow
+  throttling controls plus the latest learner debounce default alignment.
+- `phase3-measured-perf` contains the measured hot-path improvements for
+  localization, available quest redraws, quest eligibility, profile lookups,
+  `GetTime()` hoists, NPC fallback lookups, and validate-cache allocation
+  cleanup.
+- `phase2-lua50-sweep` and local `phase3-measured-perf` still contain the
+  `fix: add missing local profile in QuestieMap.ProcessQueue` commit even
+  though `main` reverted it. That commit should be removed from the integration
+  path or revalidated with a specific runtime trace before merge.
+
+## Bug found
+
+`QuestieLearner:OnCombatLogEvent` had an event-order edge case introduced by
+the bystander-kill suppression work:
+
+- `UNIT_DIED` may fire for a nearby visible death before `PARTY_KILL`.
+- The previous debounce table only stored `dstGUID -> timestamp`.
+- If `UNIT_DIED` stored the timestamp first, the later authoritative
+  `PARTY_KILL` for the player's/group's actual kill could be skipped inside the
+  five-second duplicate window.
+- That could preserve the FPS-saving bystander suppression while accidentally
+  dropping legitimate learner updates.
+
+## What changed
+
+- `Modules/QuestieLearner.lua`
+  - The kill debounce entry now stores both timestamp and event type.
+  - A later `PARTY_KILL` is allowed through if the prior debounce entry came
+    from `UNIT_DIED`.
+  - Duplicate `PARTY_KILL` events and non-authoritative duplicate events remain
+    suppressed.
+  - The prune loop remains bounded and still handles older timestamp-only
+    entries defensively.
+- `Tests/AuditFindings_spec.lua`
+  - Added a static regression asserting the event-type-aware debounce guard is
+    present, so future refactors do not accidentally reintroduce the issue.
+
+## Verification
+
+- `busted Tests\\AuditFindings_spec.lua Tests\\QuestieDB_suppression_spec.lua Tests\\QuestieArrow_spec.lua`
+  - `49 successes / 0 failures / 0 errors / 0 pending`
+- `luac5.1 -p Modules\\QuestieLearner.lua; luac5.1 -p Tests\\AuditFindings_spec.lua`
+  - Parser sanity check passed for the touched files.
+- `selene Modules\\QuestieLearner.lua Tests\\AuditFindings_spec.lua`
+  - `0 errors / 99 warnings / 0 parse errors`
+  - The warnings are existing style warnings in `QuestieLearner.lua`, mostly
+    multiple-statements-per-line and shadowing warnings, not parser failures.
+
+## Remaining branch-level decision
+
+The most robust release candidate should be an integration branch that combines
+`questie-learner-comms-improvements` with `phase3-measured-perf`, after removing
+or revalidating the reverted `QuestieMap.ProcessQueue` profile-local commit.
+Until that happens, no single branch contains every current performance fix.
+

+
+# Pass-50 - Documentation refresh for performance refactor status (2026-06-05)
+
+This pass updated the user-facing and handoff documentation to reflect the
+current learner/comms/arrow performance work and the cross-branch integration
+status.
+
+## What changed
+
+- `README.md`
+  - Expanded the repository notice to explain the active performance refactor.
+  - Added a "Current Performance Refactor Status" section with the status of
+    QuestieLearner, QuestieComms, Arrow, error suppression, and phase 3 hot-path
+    work.
+  - Added a concise in-game validation checklist for heavy kill zones, minimap
+    open, nearby-player kills, comms modes, and Arrow throttles.
+- `CHANGELOG.md`
+  - Added an `[Unreleased] - Performance Refactor Branches` section.
+  - Documented learner debounce/max-wait, bystander `UNIT_DIED` suppression,
+    `PARTY_KILL` event-order fix, live learner/comms/arrow performance options,
+    non-fatal error suppression, tooltip precedence, and phase 3 measured
+    hot-path changes.
+  - Noted that the best performance work is still split across
+    `questie-learner-comms-improvements` and `phase3-measured-perf`.
+- `release_notes.txt`
+  - Added an active refactor notice above the v1.6.3 shipped highlights.
+- `QUESTIE-LEARNER-HANDOFF.md`
+  - Added a current learner/comms performance handoff at the top.
+  - Preserved the older Sunstrider handoff below as historical context.
+- `docs/index.html`
+  - Added an "Active Performance Refactor" landing-page section.
+- `docs/changelog.html`
+  - Added an `[Unreleased]` HTML changelog section mirroring the markdown
+    changelog.
+
+## Result
+
+The docs now clearly distinguish shipped `v1.6.3` behavior from the active
+performance refactor branches, and they call out the remaining integration and
+testing requirements for the next stable release.

+
+# Pass-51 - Invalid item ID safety for item-name caching (2026-06-05)
+
+This pass fixed the crash reported from `QuestieDB.lua:335` when item-name
+lookup paths received an invalid item ID during queued item caching.
+
+## What changed
+
+- `Database/QuestieDB.lua`
+  - The 3.3.5 compatibility `Item:CreateFromItemID()` shim now routes through a
+    safe helper that validates the item ID before calling `GetItemInfo()`.
+  - Invalid or zero IDs now return an `item:<value>` placeholder instead of
+    crashing the API call.
+- `Modules/Libs/QuestieLib.lua`
+  - `CacheItemNames()` now normalizes `objectiveDB.Id` with `tonumber()`.
+  - Invalid item IDs are skipped early with a debug message instead of
+    creating an item object that can later crash on `GetItemName()`.
+  - Valid numeric IDs continue to use the existing async item-name cache flow.
+- `Modules/Network/QuestieCommsData.lua`
+  - The item tooltip branch now normalizes `objective.id` before calling
+    `QuestieDB:GetItem()` or `GetItemInfo()`.
+  - Non-numeric item IDs now degrade to a safe placeholder instead of
+    entering the same failure mode during comms tooltip building.
+- `Tests/QuestieItemNameSafety_spec.lua`
+  - Added a regression spec proving invalid item IDs do not call `GetItemInfo`
+    and instead return a placeholder item name.
+
+## Verification
+
+- `busted Tests\\QuestieItemNameSafety_spec.lua Tests\\QuestieLearner_performance_spec.lua Tests\\QuestieTooltip_precedence_spec.lua`
+  - `18 successes / 0 failures / 0 errors / 0 pending`
+- `luac5.1 -p Database\\QuestieDB.lua; luac5.1 -p Modules\\Libs\\QuestieLib.lua; luac5.1 -p Modules\\Network\\QuestieCommsData.lua`
+  - Parser sanity checks passed for the touched files.
+
+## Result
+
+Malformed item IDs can no longer crash the item-name caching path, and the fix
+stays aligned with the active learner branch because it preserves normal
+behavior for valid item IDs while safely degrading the invalid cases.

+# Pass-51 - Learner/static source mode switch for display testing (2026-06-05)
+
+This pass added a Database-tab mode switch so learner capture can stay on while
+display decisions can be forced to learner-only, static-only, or neither for
+controlled testing.
+
+## What changed
+
+- `Modules/Options/DatabaseTab/QuestieOptionsDatabase.lua`
+  - Added `Enable Learner Recording` to control the learner capture/injection
+    toggle independently.
+  - Added `Data Source Mode` with `auto`, `learner`, `static`, and `none`
+    choices.
+  - Changing either control now immediately reapplies the active mode and
+    refreshes quest/tracker state.
+- `Modules/QuestieLearner.lua`
+  - Added `GetDataSourceMode`, `IsLearnerLiveEnabled`, and `ApplyDataSourceMode`.
+  - Captured a static override snapshot so mode changes can rebuild the active
+    view without a reload.
+  - Gated live injection, cross-links, tooltip hooks, and pin refreshes on the
+    selected mode.
+  - Added cache resets so changing the mode does not leave stale query results.
+- `Database/QuestieDB.lua`
+  - Static pin suppression now respects the selected data source mode instead
+    of only the old `prioritizeMyData` flag.
+- `Modules/Quest/QuestieQuest.lua`
+  - Static spawn suppression now only engages when learner data is allowed to
+    influence display.
+- `Modules/Quest/QuestieQuestPrivates.lua`
+  - NPC/object spawn selection now respects learner-only / static-only / none
+    modes for map pin behavior.
+- `Modules/Tooltips/Tooltip.lua`
+  - Learned tooltip fallback is disabled when the selected mode is static-only
+    or none.
+- `Modules/Options/QuestieOptionsDefaults.lua`
+  - Added the default `dataSourceMode = "auto"` profile setting.
+- `Tests/QuestieLearnerDataSourceMode_spec.lua`
+  - Added a regression spec covering the new mode selector and live gating.

+
+# Pass-52 - Learner self-sustaining DB fallback (2026-06-05)
+
+This pass made learner mode read from the saved learner tables directly when

+source path instead of only a live override layer.
+
+## What changed
+
+- `Database/QuestieDB.lua`
+  - `GetQuest`, `GetNPC`, `GetObject`, and `GetItem` now prefer
+    `Questie.dbLearner.global.*` records when learner mode is active or when
+    the compiled/static source is missing.
+  - Auto mode still prefers compiled/static data first, but it can now fall
+    back to learner data when a record exists and the static query returns nil.
+- `Modules/Quest/QuestieQuestPrivates.lua`
+  - Pin builders now read NPC/object display data through `QuestieDB:GetNPC()`
+    and `QuestieDB:GetObject()` instead of static-only single-field queries.
+  - That keeps the pin builders aligned with the learner-aware DB getters and
+    prevents learner-only mode from quietly depending on the static query path.
+- `Tests/QuestieLearnerDataSourceMode_spec.lua`
+  - Added runtime coverage proving learner-mode NPC/object lookups resolve from
+    learner saved variables when the compiled query returns nothing.

+## Result

+# Pass-53 - Immediate learner pin rendering and available quest guard (2026-06-05)
+
+This pass removed the remaining gap between kill evidence and visible learner
+pins, then hardened the available quest scanner so unresolved quest IDs no

+
+## What changed
+
+- `Database/QuestieDB.lua`
+  - Learner-mode NPC reads now convert immediate GUID-kill evidence from
+    `dbLearner.global.npcs[npcId][8]` into a real `spawns` table.
+  - That lets pin builders consume learner kill coordinates immediately instead
+    of waiting for the later confidence merge path.
+- `Modules/Quest/QuestieQuestPrivates.lua`
+  - Learner mode no longer clears out the spawn table after `GetNPC()` or
+    `GetObject()` has already supplied learner-backed coordinates.
+  - Objective pin building now keeps those learned spawns available to the map
+    layer instead of collapsing them back to empty.
+- `Modules/Quest/AvailableQuests.lua`
+  - Guarded the draw thread so unresolved quest IDs are skipped safely instead
+    of indexing a nil quest record.
+  - Dedupe the skip message so the same unavailable quest only logs once per
+    session instead of on every redraw.
+- `Tests/QuestieLearnerDataSourceMode_spec.lua`
+  - Added a regression proving learner kill evidence becomes spawn coordinates
+    immediately in learner mode.
+- `Tests/QuestieAvailableQuests_spec.lua`
+  - Added a regression proving unavailable quests are skipped before the draw
+    path touches `tagInfoWasCached`.

+
+# 2026-06-05 — Data Source Mode Cohesion, Pin Refresh Latency, and Pin Clustering Knob
+
+## Summary
+
+Three related areas were addressed after the immediate-spawn work above:
+
+1. Switching the Data Source Mode (Auto / Learner / Static / Neither) did not
+   reliably take effect — including a case where it could never switch back to
+   the static database even across `/reload`.
+2. Newly learned spawns were slow to redraw pins because two trailing-debounce
+   stages were stacked on the live-learn path.
+3. The density-adaptive pin clustering that was previously commented out needed
+   re-implementing as a user-tunable knob, plus a guaranteed coincident-pin
+   deduplication baseline.
+
+## Root causes
+
+- **Mode lock-in.** `QuestieDB.baseDatabaseMissing` was a single global flag set
+  to `true` when ANY one of the four core stores (`npcData`, `objectData`,
+  `questData`, `itemData`) failed to load. Both the per-read DB functions and
+  `GetDataSourceMode()` force learner mode whenever `IsBaseDatabaseMissing()` is
+  true, so a single missing/format-mismatched sub-table pinned the entire addon
+  to learner data and survived `/reload` (the flag is recomputed identically at
+  load).
+- **Learner leak into Static/Neither.** The per-read fallback
+  (`if not rawdata and learnerRecord then rawdata = learnerRecord`) ran in the
+  `else` branch for every non-learner mode, so Static and Neither silently used
+  learner records when the static DB lacked an entry.
+- **Dead redraw on mode switch.** `ApplyLearnerMode` imported
+  `"QuestieEventHandler"` (the module is registered as `"QuestEventHandler"`) and
+  called `UpdateAllQuests`, which lives on the private table — so the import
+  returned nil and available-quest pins were never redrawn on a mode switch.
+- **Stale zone cache.** `ApplyDataSourceMode` cleared the quest/npc/item/object
+  caches but not `zoneCache`, so per-zone quest results lingered after a switch.
+- **Stacked pin-refresh debounce.** A learned kill flowed through
+  `liveNpcUpdateDelay` (NPC live-update flush) and THEN a separate
+  `pinRefreshDelay` gate before `UpdateQuest`. Because the only caller of the
+  pin-invalidation path is the already-debounced NPC flush, the second stage was
+  pure added latency (~1.5s Balanced, ~4s Low), with two independent
+  `pinRefreshMaxWait` caps under sustained kills.
+
+## What changed
+
+- `Database/QuestieDB.lua`
+  - `IsBaseDatabaseMissing()` now reports missing only when ALL four core stores
+    failed; added `IsStoreMissing(storeKey)` for per-store checks.
+  - Each read (`GetNPC` / `GetQuest` / `GetItem` / `GetObject`) gates force-learner
+    on its own store and only overlays a learner-record fallback in Auto mode.
+  - Added `ClearModeCaches()` which clears quest/item/npc/object AND zone caches.
+- `Modules/QuestieLearner.lua`
+  - `ApplyDataSourceMode` now calls `ClearModeCaches()`.
+  - Split the active-quest pin flush into a debounce-gate wrapper plus a
+    `_DoFlushActiveQuestPins` body. The NPC live-update flush now suppresses the
+    redundant second debounce and force-flushes pins once, immediately.
+  - Hardened the flush gate so it only defers while there is genuine pending
+    activity (fixes an infinite timer re-arm exposed by the direct flush).
+- `Modules/Options/DatabaseTab/QuestieOptionsDatabase.lua`
+  - Mode switches now refresh through `QuestieQuest:SmoothReset()` (clears notes
+    and tooltips, recalculates and redraws available quests, re-updates active
+    quests, refreshes the tracker).
+- `Modules/Quest/QuestieQuest.lua`
+  - Re-implemented density-adaptive clustering, scaled by a new
+    `clusterDensityAggressiveness` profile knob. The intentional per-zone
+    (Sunstrider Isle, uiMapID 1241, range 0) and object-icon (`range * 0.2`)
+    overrides are preserved and still take precedence.
+- `Modules/Map/QuestieMapUtils.lua`
+  - `CalcHotzones` now always merges coincident pins
+    (within `COINCIDENT_EPSILON`), independent of the clustering range, so two
+    icons never stack on the same spot even when clustering is disabled.
+- `Modules/Options/QuestieOptionsDefaults.lua`,
+  `Modules/Options/AdvancedTab/QuestieOptionsAdvanced.lua`
+  - Added the `clusterDensityAggressiveness` default (35) and a real-time
+    Advanced-tab slider that redraws via `QuestieOptions:ClusterRedraw`.
+- Tests
+  - `Tests/QuestieLearnerDataSourceMode_spec.lua`: partial-missing store handling,
+    Static/Neither no-leak, Auto overlay, full cache clear, SmoothReset wiring.
+  - `Tests/QuestieLearner_performance_spec.lua`: pins force-flush within a single
+    NPC live-update round and draining terminates (infinite-loop guard).
+  - `Tests/QuestiePinClustering_spec.lua` (new): coincident dedup, distinct-pin
+    preservation at range 0, range-based clustering, cross-map isolation, and
+    knob wiring.
+
+## Verification
+
+- `luac5.1 -p` on every changed Lua file.
+- `busted` full suite: 100 successes / 4 failures (the 4 failures are the
+  pre-existing, unrelated `QuestieArrowAssets_spec` asset checks).
+
+## Result
+
+All four data-source modes now switch live and cohesively (and partial static
+DB failures no longer trap the addon in learner mode). Newly learned spawns
+redraw within a single debounce window. Dense kill objectives can be
+consolidated to taste via the new aggressiveness knob, while coincident pins are
+always deduplicated and the curated per-zone/object overrides remain intact.
+
+### Follow-up — learner pin-per-kill fix
+
+Learner kill evidence was rendering one pin per kill. Kill coordinates come from
+the player's position at kill time and respawns carry fresh GUIDs, so repeated
+kills at the same spawn drifted just enough to defeat the exact-match dedup in
+`_BuildSpawnTableFromGuidEvidence` (`Database/QuestieDB.lua`) and the
+full-precision grouping key in `_MergeSpawnEvidence` (`Modules/QuestieLearner.lua`).
+
+- `_BuildSpawnTableFromGuidEvidence` now merges evidence coords within a small
+  radius (distance test, not a grid bucket — avoids the cell-boundary split where
+  two near-identical coords land in different buckets) into one pin per spawn.
+- `_MergeSpawnEvidence` now groups kills by a per-zone coordinate bucket
+  (`GetCoordGridForZone`) instead of exact coords, so one location accumulates
+  enough evidence to clear the >60% confidence threshold instead of every kill
+  registering as its own single-count "location".
+- The `[7]` spawn path already deduped via `InsertIfNewBucket`; only the GUID
+  evidence (`[8]`) consumers needed the fix.
+- The merge radius is user-tunable via the new `spawnDedupRadius` learner setting
+  (default 4.0, map-percent) and a "Spawn Pin Dedup Radius" slider on the
+  Advanced tab. `_BuildSpawnTableFromGuidEvidence` reads it through
+  `_GetSpawnDedupRadius` (0 = exact-match only / every distinct position shown);
+  changing it clears the NPC spawn cache and triggers a live redraw.
+- Regressions added in `Tests/QuestieLearnerDataSourceMode_spec.lua`: many nearby
+  kills collapse to one pin, genuinely separate spawns stay distinct, radius 0
+  disables proximity merge, and a larger radius widens merging.
+  `Tests/QuestiePinClustering_spec.lua` asserts the knob wiring (default + UI +
+  cache-clear redraw).
