 # Changelog

+## Code Review (2026-03-19) — Kilo Code
+
+Reviewed core modules for Lua 5.0/5.1/5.2/5.3 compatibility, code quality, and new feature suggestions.
+
+### Issues Identified
+
+| Severity | Count | Details |
+|----------|-------|---------|
+| HIGH | 2 | `C_Timer` OnUpdate missing elapsed param; `IsAchievementCompleted` wrong check |
+| HIGH | 1 | `C_Map.GetPlayerMapPosition` passed numeric ID to legacy API expecting unit string |
+| HIGH | 1 | Secure hook taint: hooks calling insecure functions from protected execution contexts |
+| MEDIUM | 5 | C_Map.GetBestMapForUnit stub limitation; duplicate polyfills; vestigial UI elements |
+| LOW | 8 | File size concerns; duplicate function definitions in QuestieLearner |
+
+### HIGH Priority Fixes (APPLIED)
+
+1. **[FIXED] QuestieCompat.lua:147** — `C_Timer` OnUpdate now uses `function(self, elapsed)` instead of computing `1/GetFramerate()`. This provides precise frame timing and eliminates timer drift.
+2. **[FIXED] QuestieCompat.lua:443** — `IsAchievementCompleted` now uses `select(4, GetAchievementInfo(...))` instead of criteria count to properly check completion status.
+3. **[FIXED] QuestieCompat.lua:416** — `C_Map.GetPlayerMapPosition` now calls `GetPlayerMapPosition("player")` directly instead of passing the numeric `uiMapID` to the legacy API. On pre-Cata clients, the legacy API does not accept a map ID argument, causing incorrect results.
+4. **[FIXED] QuestieLearner.lua** — `GetNpcIdFromGUID` and `GetObjectIdFromGUID` were called by event handlers before their definitions. Added forward declarations before event handlers (line 1168) and removed duplicate definitions that existed later in the file. This fixes "attempt to call global 'GetNpcIdFromGUID' (a nil value)" errors.
+5. **[FIXED] Taint Fix: Secure Hook Guards** — Added `InCombatLockdown()` guards and `pcall` wrappers to secure hooks to prevent tainting protected execution paths. Affected hooks: `SetItemRef` (QuestieDebugOffer.lua), `DeleteCursorItem` (QuestEventHandler.lua), `QuestLogTitleButton_OnClick` (QuestLinks/Hooks.lua), `ChatFrame_OnHyperlinkShow` (QuestLinks/Link.lua), `GetQuestReward`, `SetAbandonQuest`, `AbandonQuest` (Compat.lua). This resolves "ADDON_ACTION_BLOCKED: tried to call UseAction()" errors.
+
+### Architecture Recommendations
+
+- Split `QuestieQuest.lua` (1400+ lines) into: QuestieQuestAccept, QuestieQuestComplete, QuestieQuestUpdate, QuestieQuestIcons
+- Split `QuestieTracker.lua` (1103+ lines) into: TrackerQuestOperations, TrackerUIUpdate
+- Split `QuestieLearner.lua` into: LearnerNPCs, LearnerQuests, LearnerItems, LearnerObjects, LearnerCrossLink, LearnerEvents
+
+### Suggested Features
+
+1. **Quest Route Optimization** (HIGH) — Calculate optimal routes between objectives
+2. **Dynamic Quest Timer Display** (MEDIUM) — Show timers on map icons
+3. **Quest Difficulty Rating** (MEDIUM) — Help players identify appropriate quests
+4. **Collaborative Quest Sharing** (MEDIUM) — Enhanced QuestieLearner sharing
+5. **Performance Profiler Integration** (LOW) — Frame rate impact warnings
+6. **Mob Spawn Prediction** (LOW) — Predict farming locations
+

+
+## v1.4.0 — Code Review Fixes & Taint Resolution
+
+- **[Code Review]** Comprehensive code review of core modules for Lua 5.0/5.1/5.2/5.3 compatibility and code quality.
+- **[C_Timer Fix]** Fixed `C_Timer` OnUpdate to use precise `(self, elapsed)` parameter instead of `1/GetFramerate()`.
+- **[Achievement Fix]** Fixed `IsAchievementCompleted` to properly check completion boolean via `select(4, GetAchievementInfo(...))`.
+- **[Map Fix]** Fixed `C_Map.GetPlayerMapPosition` to use correct legacy API (`GetPlayerMapPosition("player")`).
+- **[QuestieLearner Fix]** Fixed `GetNpcIdFromGUID` and `GetObjectIdFromGUID` being called before definition.
+- **[Taint Fix]** Added `InCombatLockdown()` guards and `pcall` wrappers to secure hooks to prevent `ADDON_ACTION_BLOCKED: UseAction()` errors.
+
 ## v1.3.9 — BackdropTemplate & Tracking Reliability

- **[Quest Tracking]** Significantly improved the reliability of shift-clicking to track or untrack quests. Added more robust user action detection to identify clicks directly in the tracker or the Quest Log.
- **[Quest Re-tracking]** Resolved an issue where hidden quests would refuse to re-track after being manually untracked. Toggling quests back on is now consistently recognized as a manual user action across all WoW versions.
- **[AceGUI Fix]** Fixed a critical crash: `Couldn't find inherited node "BackdropTemplate"`. Implemented a cross-version safe method for frame inheritance in AceGUI-3.0, ensuring stability on WotLK and Classic clients.
- **[Verification]** Performed a comprehensive syntax audit using `luaparse` for all modified core files and AceGUI widgets.
+- **[Quest Tracking]** Significantly improved the reliability of shift-clicking to track or untrack quests.
+- **[Quest Re-tracking]** Resolved an issue where hidden quests would refuse to re-track after being manually untracked.
+- **[AceGUI Fix]** Fixed critical crash: `Couldn't find inherited node "BackdropTemplate"`.

+            <li><strong>[QuestieLearner.lua]</strong> Fixed <code>GetNpcIdFromGUID</code> and <code>GetObjectIdFromGUID</code> being called before definition. Added forward declarations before event handlers (line 1168) and removed duplicate definitions. This fixes "attempt to call global 'GetNpcIdFromGUID' (a nil value)" errors.</li>
+            <li><strong>[Taint Fix: Secure Hook Guards]</strong> Added <code>InCombatLockdown()</code> guards and <code>pcall</code> wrappers to secure hooks to prevent tainting protected execution paths. Affected hooks: <code>SetItemRef</code> (QuestieDebugOffer.lua), <code>DeleteCursorItem</code> (QuestEventHandler.lua), <code>QuestLogTitleButton_OnClick</code> (QuestLinks/Hooks.lua), <code>ChatFrame_OnHyperlinkShow</code> (QuestLinks/Link.lua), <code>GetQuestReward</code>, <code>SetAbandonQuest</code>, <code>AbandonQuest</code> (Compat.lua). This resolves "ADDON_ACTION_BLOCKED: tried to call UseAction()" errors.</li>

+        <h2 id="v140">v1.4.0 — Code Review Fixes &amp; Taint Resolution</h2>
+        <ul>
+            <li><strong>[Code Review]</strong> Comprehensive code review of core modules for Lua 5.0/5.1/5.2/5.3 compatibility and code quality.</li>
+            <li><strong>[C_Timer Fix]</strong> Fixed <code>C_Timer</code> OnUpdate to use precise <code>(self, elapsed)</code> parameter instead of <code>1/GetFramerate()</code>.</li>
+            <li><strong>[Achievement Fix]</strong> Fixed <code>IsAchievementCompleted</code> to properly check completion boolean via <code>select(4, GetAchievementInfo(...))</code>.</li>
+            <li><strong>[Map Fix]</strong> Fixed <code>C_Map.GetPlayerMapPosition</code> to use correct legacy API.</li>
+            <li><strong>[QuestieLearner Fix]</strong> Fixed <code>GetNpcIdFromGUID</code> and <code>GetObjectIdFromGUID</code> being called before definition.</li>
+            <li><strong>[Taint Fix]</strong> Added <code>InCombatLockdown()</code> guards and <code>pcall</code> wrappers to secure hooks to prevent <code>ADDON_ACTION_BLOCKED: UseAction()</code> errors.</li>

        <h2 id="v137">v1.3.7 — Quest Tracking &amp; Robustness</h2>
        <ul>
            <li><strong>[Quest Tracking]</strong> Resolved inconsistent quest tracking/untracking by making the tracking state idempotent. This eliminates "doing nothing" results while toggling quests in the Quest Log and prevents tracking loops caused by Blizzard's auto-track feature.</li>
