+# Implementation Plan: Line Prefix Speaker Format (Revised)
+## Actionable Development Guide
+
+**Last Updated:** November 23, 2025  
+**Status:** Ready for Implementation
+
+**Target Files:**
+- `public/break_escape/js/minigames/person-chat/person-chat-minigame.js`
+- `public/break_escape/js/minigames/person-chat/person-chat-ui.js`
+- `public/break_escape/css/person-chat-minigame.css`
+- `public/break_escape/js/minigames/helpers/chat-helpers.js`
+
+---
+
+## Critical Implementation Context
+
+### Current Code State
+1. **`determineSpeaker()` exists but is unused** (lines 500-543 in person-chat-minigame.js)
+2. **Speaker detection is hardcoded** in `createDialogueBlocks()` (line 699)
+3. **Three `showDialogue()` calls** in person-chat-ui.js pass 2-3 parameters (line 216)
+4. **20 `showDialogue()` call sites** throughout codebase using 3-parameter signature
+
+### Compatibility Strategy
+- **No breaking changes** - All methods use optional parameters with defaults
+- **Backward compatible** - Existing tag-based conversations work unchanged
+- **Minimal API changes** - Only add optional parameters, don't remove or change existing ones
+
+---
+
+## Phase 0: Pre-Implementation Refactoring (CRITICAL)
+
+### 0.1 Consolidate Speaker Detection Logic
+
+**Current Problem:** Speaker detection happens in two places:
+- `determineSpeaker()` method exists but is never called
+- `createDialogueBlocks()` has inline speaker detection (line 699-705)
+
+This causes maintenance issues and makes it hard to add new speaker detection features.
+
+**Step 1: Refactor createDialogueBlocks() to use determineSpeaker()**
+
+In `person-chat-minigame.js`, line 699-705 (approximate):
+
+```javascript
+// BEFORE: Inline speaker detection
+createDialogueBlocks(lines, tags) {
+    const blocks = [];
+    let currentBlock = null;
+    
+    for (const line of lines) {
+        let speaker = this.npc.id;  // ← Hardcoded default
+        if (tag.includes('speaker:player')) {
+            speaker = 'player';
+        } else if (tag.includes('speaker:npc:')) {
+            // Extract NPC ID...
+        }
+        // ... rest of block building
+    }
+}
+
+// AFTER: Use determineSpeaker()
+createDialogueBlocks(lines, tags, result) {
+    const blocks = [];
+    let currentBlock = null;
+    
+    for (const line of lines) {
+        const speaker = this.determineSpeaker(result, line);
+        // ... rest of block building
+    }
+}
+```
+
+**Step 2: Add State Locking**
+
+Add to PersonChatMinigame constructor:
+```javascript
+this.isProcessingDialogue = false;
+```
+
+Add to beginning of displayAccumulatedDialogue():
+```javascript
+if (this.isProcessingDialogue) {
+    console.log('⏳ Already processing dialogue, ignoring');
+    return;
+}
+this.isProcessingDialogue = true;
+```
+
+Add to end of displayDialogueBlocksSequentially() (all exit paths):
+```javascript
+this.isProcessingDialogue = false;
+```
+
+**Step 3: Fix Memory Leak**
+
+In PersonChatUI, add destroy() or conversation-end cleanup:
+```javascript
+destroy() {
+    if (this.charactersWithParallax) {
+        this.charactersWithParallax.clear();
+    }
+    // ... other cleanup
+}
+```
+
+**✅ Acceptance Criteria:**
+- [ ] All existing tag-based conversations work unchanged
+- [ ] No API changes to public methods
+- [ ] `determineSpeaker()` is the single source of speaker detection logic
+- [ ] No race conditions during rapid dialogue advancement
+
+---
+
+## Phase 1: Core Parsing Functions
+
+### 1.1 Add parseDialogueLine() Method
+
+**Location:** `person-chat-minigame.js` - Add as method after line 543 (after determineSpeaker())
+
+**Purpose:** Parse a single dialogue line for speaker prefix format
+
+**Key Design Decisions:**
+1. Validates that dialogue text is not empty (ignores "Speaker: " lines)
+2. Case-insensitive speaker IDs ("Player:", "player:", "PLAYER:" all work)
+3. First colon is delimiter ("Speaker: Text: with: colons" → speaker="Speaker", text="Text: with: colons")
+4. Rejects prefixes where speaker ID doesn't exist in character index
+5. Handles Narrator[character_id]: syntax for narrator with character portrait
+
+**Implementation:**
+
+```javascript
+/**
+ * Parse a dialogue line for speaker prefix format
+ * 
+ * Formats Supported:
+ * - "NPC_ID: Dialogue text" → Speaker detected, text extracted
+ * - "Player: Dialogue text" → Player character, case-insensitive
+ * - "npc: Dialogue text" → Main conversation NPC shorthand
+ * - "Narrator: Text" → Narrative passage, no portrait
+ * - "Narrator[npc_id]: Text" → Narrative with character portrait in view
+ * - "Narrator[]: Text" → Narrative explicitly with no portrait
+ * - "Just text" → No prefix detected, text returned as-is
+ * - "Speaker: " → Empty text rejected, no prefix
+ * 
+ * @param {string} line - Single line of dialogue text
+ * @returns {Object} { speaker, text, hasPrefix, isNarrator, narratorCharacter }
+ */
+parseDialogueLine(line) {
+    if (!line || typeof line !== 'string') {
+        return { speaker: null, text: line || '', hasPrefix: false, isNarrator: false, narratorCharacter: null };
+    }
+    
+    const trimmed = line.trim();
+    if (!trimmed) {
+        return { speaker: null, text: '', hasPrefix: false, isNarrator: false, narratorCharacter: null };
+    }
+    
+    // Pattern 1: Narrator with optional character: Narrator[character_id]: text
+    const narratorWithCharPattern = /^Narrator\[([A-Za-z_][A-Za-z0-9_]*|)\]:\s+(.+)$/i;
+    const narratorMatch = trimmed.match(narratorWithCharPattern);
+    
+    if (narratorMatch) {
+        const characterId = narratorMatch[1] || null;
+        const dialogueText = narratorMatch[2];
+        
+        if (!dialogueText || !dialogueText.trim()) {
+            console.warn(`⚠️ Empty dialogue after Narrator prefix: "${trimmed}"`);
+            return { speaker: null, text: trimmed, hasPrefix: false, isNarrator: false, narratorCharacter: null };
+        }
+        
+        let normalizedCharacter = null;
+        if (characterId) {
+            normalizedCharacter = this.normalizeSpeakerId(characterId);
+            if (!normalizedCharacter) {
+                console.warn(`⚠️ Narrator character not found: ${characterId}`);
+                normalizedCharacter = null;
+            }
+        }
+        
+        return {
+            speaker: 'narrator',
+            text: dialogueText,
+            hasPrefix: true,
+            isNarrator: true,
+            narratorCharacter: normalizedCharacter
+        };
+    }
+    
+    // Pattern 2: Basic speaker prefix: SPEAKER_ID: text
+    const prefixPattern = /^([A-Za-z_][A-Za-z0-9_]*):\s+(.+)$/i;
+    const match = trimmed.match(prefixPattern);
+    
+    if (!match) {
+        return { speaker: null, text: trimmed, hasPrefix: false, isNarrator: false, narratorCharacter: null };
+    }
+    
+    const speakerId = match[1];
+    const dialogueText = match[2];
+    
+    if (!dialogueText || !dialogueText.trim()) {
+        console.warn(`⚠️ Empty dialogue after speaker prefix "${speakerId}:"`);
+        return { speaker: null, text: trimmed, hasPrefix: false, isNarrator: false, narratorCharacter: null };
+    }
+    
+    const normalizedSpeaker = this.normalizeSpeakerId(speakerId);
+    if (!normalizedSpeaker) {
+        return { speaker: null, text: trimmed, hasPrefix: false, isNarrator: false, narratorCharacter: null };
+    }
+    
+    return {
+        speaker: normalizedSpeaker,
+        text: dialogueText,
+        hasPrefix: true,
+        isNarrator: false,
+        narratorCharacter: null
+    };
+}
+```
+
+### 1.2 Add normalizeSpeakerId() Method
+
+**Location:** `person-chat-minigame.js` - Add as method after parseDialogueLine()
+
+**Purpose:** Convert raw speaker ID to canonical form and validate existence
+
+**Implementation:**
+
+```javascript
+/**
+ * Normalize speaker ID for consistent lookup
+ * 
+ * Valid inputs and outputs:
+ * - 'player' → 'player' (always valid, special player character)
+ * - 'npc' → this.npc.id (main conversation NPC shorthand)
+ * - 'test_npc_back' → 'test_npc_back' (if exists in character index)
+ * - 'Player' → 'player' (case-insensitive)
+ * - 'nonexistent_npc' → null (character not found)
+ * 
+ * @param {string} speakerId - Raw speaker ID from dialogue line
+ * @returns {string|null} Normalized speaker ID, or null if invalid/not found
+ */
+normalizeSpeakerId(speakerId) {
+    if (!speakerId || typeof speakerId !== 'string') {
+        return null;
+    }
+    
+    const lower = speakerId.toLowerCase();
+    
+    // Special case 1: 'player' is always valid
+    if (lower === 'player') {
+        return 'player';
+    }
+    
+    // Special case 2: 'npc' is shorthand for main conversation NPC
+    if (lower === 'npc') {
+        return this.npc?.id || null;
+    }
+    
+    // Special case 3: 'narrator' is always valid
+    if (lower === 'narrator') {
+        return 'narrator';
+    }
+    
+    // Try direct lookup
+    if (this.characters && this.characters[speakerId]) {
+        return speakerId;
+    }
+    
+    // Try case-insensitive lookup
+    if (this.characters) {
+        const key = Object.keys(this.characters).find(k => k.toLowerCase() === lower);
+        if (key) {
+            return key;
+        }
+    }
+    
+    // Speaker not found
+    console.warn(`⚠️ Speaker ID not found: ${speakerId}`);
+    return null;
+}
+```
+
+**✅ Acceptance Criteria:**
+- [ ] `parseDialogueLine()` parses all prefix formats correctly
+- [ ] Edge cases handled (empty text, invalid speakers, malformed lines)
+- [ ] `normalizeSpeakerId()` returns correct normalized IDs
+- [ ] Both methods handle missing/invalid data gracefully
+- [ ] Unit tests pass for all formats
+
+---
+
+## Phase 2: Enhance Speaker Determination
+
+### 2.1 Update determineSpeaker() Method
+
+**Location:** `person-chat-minigame.js` - Replace existing method (lines 500-543)
+
+**Key Changes:**
+1. Add optional `textLine` parameter to specify which line to check
+2. Check for prefix format BEFORE tag-based detection
+3. Maintain backward compatibility with existing tag logic
+
+**Implementation:**
+
+```javascript
+/**
+ * Determine who is speaking based on prefix format OR Ink tags
+ * 
+ * Priority order:
+ * 1. Line prefix format (SPEAKER_ID: text) - if available
+ * 2. Ink tags (#speaker:player, #speaker:npc:id, etc.) - fallback
+ * 3. Default to main conversation NPC - if no prefix/tags found
+ * 
+ * @param {Object} result - Result object from conversation.continue()
+ * @param {string} textLine - Optional specific line to check for prefix
+ *                            If not provided, uses first line of result.text
+ * @returns {string} Speaker character ID ('player', NPC ID, or 'narrator')
+ */
+determineSpeaker(result, textLine = null) {
+    // Priority 1: Check for line prefix format
+    if (textLine || (result && result.text)) {
+        const lineToCheck = textLine || result.text.split('\n')[0];
+        const parsed = this.parseDialogueLine(lineToCheck);
+        
+        if (parsed.hasPrefix && parsed.speaker) {
+            console.log(`🎯 Speaker detected from prefix: ${parsed.speaker}`);
+            return parsed.speaker;
+        }
+    }
+    
+    // Priority 2: Fall back to tag-based detection (existing logic)
+    if (!result || !result.tags || result.tags.length === 0) {
+        return this.npc?.id || 'player'; // Default to main NPC
+    }
+    
+    // Parse tags in reverse order to find most recent speaker tag
+    for (let i = result.tags.length - 1; i >= 0; i--) {
+        const tag = result.tags[i].trim().toLowerCase();
+        
+        if (tag.startsWith('speaker:')) {
+            const parts = tag.split(':');
+            
+            if (parts.length === 2) {
+                // Format: speaker:player or speaker:npc
+                if (parts[1] === 'player') return 'player';
+                if (parts[1] === 'npc') return this.npc?.id || 'player';
+            } else if (parts.length >= 3) {
+                // Format: speaker:npc:character_id (join all parts after 'speaker:npc:')
+                const characterId = parts.slice(2).join(':');
+                if (this.characters && this.characters[characterId]) {
+                    return characterId;
+                }
+            }
+        }
+        // Also support shorthand tags
+        else if (tag === 'player') {
+            return 'player';
+        } else if (tag === 'npc') {
+            return this.npc?.id || 'player';
+        }
+    }
+    
+    // Default to main conversation NPC
+    return this.npc?.id || 'player';
+}
+```
+
+**Backward Compatibility:**
+- ✅ Existing calls without `textLine` parameter still work
+- ✅ Falls back to tag-based detection if no prefix found
+- ✅ Maintains existing default behavior
+
+**✅ Acceptance Criteria:**
+- [ ] Prefix format takes priority over tags
+- [ ] Tags still work when no prefix found
+- [ ] Default to main NPC when neither prefix nor tags present
+- [ ] All 20 existing showDialogue() call sites work unchanged
+- [ ] Mixed format (prefix + tags) works correctly
+
+---
+
+## Phase 3: Multi-Line Dialogue with Speaker Changes
+
+### 3.1 Update createDialogueBlocks() to Support Line Prefixes
+
+**Location:** `person-chat-minigame.js` - lines 677-744
+
+**Current State:** Function uses tag-based grouping
+**New State:** Function uses line-by-line prefix parsing
+
+**Key Changes:**
+1. Now receives `result` object as third parameter (for tag fallback)
+2. Parses each line with `parseDialogueLine()`
+3. Groups lines by speaker
+4. Returns blocks with structure: `{ speaker, text, isNarrator, narratorCharacter }`
+
+**Implementation:**
+
+```javascript
+/**
+ * Build dialogue blocks from lines, grouping by speaker
+ * 
+ * Each block represents dialogue from a single speaker before switching.
+ * Lines without prefix inherit the previous speaker.
+ * First line without prefix defaults to main NPC.
+ * 
+ * @param {Array<string>} lines - Array of dialogue lines
+ * @param {Object} tags - Tag array from result (for backward compatibility)
+ * @param {Object} result - Result object for tag-based fallback
+ * @returns {Array} Array of blocks: { speaker, text, isNarrator, narratorCharacter }
+ */
+createDialogueBlocks(lines, tags, result) {
+    const blocks = [];
+    let currentBlock = null;
+    
+    for (const line of lines) {
+        if (!line || !line.trim()) {
+            continue; // Skip empty lines
+        }
+        
+        // Parse line for speaker prefix
+        const parsed = this.parseDialogueLine(line);
+        
+        let lineSpeaker;
+        let isLineNarrator = false;
+        let narratorCharacter = null;
+        
+        if (parsed.hasPrefix && parsed.speaker) {
+            // Prefix found - use parsed speaker
+            lineSpeaker = parsed.speaker;
+            isLineNarrator = parsed.isNarrator;
+            narratorCharacter = parsed.narratorCharacter;
+        } else if (currentBlock) {
+            // No prefix - continue with current speaker
+            lineSpeaker = currentBlock.speaker;
+            isLineNarrator = currentBlock.isNarrator;
+            narratorCharacter = currentBlock.narratorCharacter;
+        } else {
+            // First line with no prefix - use tag-based or default
+            lineSpeaker = this.determineSpeaker(result);
+            isLineNarrator = false;
+            narratorCharacter = null;
+        }
+        
+        // Decide whether to add to current block or start new block
+        if (currentBlock &&
+            currentBlock.speaker === lineSpeaker &&
+            currentBlock.isNarrator === isLineNarrator &&
+            currentBlock.narratorCharacter === narratorCharacter) {
+            // Same speaker - add to current block
+            currentBlock.text += '\n' + (parsed.hasPrefix ? parsed.text : line);
+        } else {
+            // Speaker change - start new block
+            if (currentBlock) {
+                blocks.push(currentBlock);
+            }
+            
+            currentBlock = {
+                speaker: lineSpeaker,
+                text: parsed.hasPrefix ? parsed.text : line,
+                isNarrator: isLineNarrator,
+                narratorCharacter: narratorCharacter
+            };
+        }
+    }
+    
+    // Don't forget the last block
+    if (currentBlock) {
+        blocks.push(currentBlock);
+    }
+    
+    return blocks;
+}
+```
+
+**Update displayAccumulatedDialogue():**
+
+Call `createDialogueBlocks()` with new parameter:
+
+```javascript
+displayAccumulatedDialogue(result) {
+    if (!result.text || !result.text.trim()) {
+        // ... existing checks ...
+    }
+    
+    // Process game action tags
+    if (result.tags && result.tags.length > 0) {
+        processGameActionTags(result.tags, this.ui);
+    }
+    
+    // Build dialogue blocks (now with prefix support)
+    const lines = result.text.split('\n').filter(line => line.trim());
+    const dialogueBlocks = this.createDialogueBlocks(lines, result.tags, result);
+    
+    // Display blocks sequentially
+    this.displayDialogueBlocksSequentially(dialogueBlocks, result, 0);
+}
+```
+
+**✅ Acceptance Criteria:**
+- [ ] Lines with prefixes grouped by speaker correctly
+- [ ] Lines without prefixes inherit previous speaker
+- [ ] First line without prefix uses tag-based or default speaker
+- [ ] Multi-speaker conversations display correctly
+- [ ] Backward compatible with existing tag-based grouping
+- [ ] Performance acceptable (minimal regex overhead)
+
+---
+
+## Phase 4: Narrator Support in UI
+
+### 4.1 Update showDialogue() Signature
+
+**Location:** `person-chat-ui.js` - line 216
+
+**Current Signature:**
+```javascript
+showDialogue(text, characterId = 'npc', preserveChoices = false)
+```
+
+**New Signature:**
+```javascript
+showDialogue(text, speaker = 'npc', preserveChoices = false, isNarrator = false, narratorCharacter = null)
+```
+
+**Implementation Notes:**
+- Add two optional parameters at end (backward compatible)
+- Parameter 1-3 maintain exact same behavior
+- Parameter 4-5 are new narrator features
+- All 20 existing call sites work without modification
+
+```javascript
+/**
+ * Display dialogue text with speaker and optional narrator mode
+ * 
+ * @param {string} text - Dialogue text to display
+ * @param {string} speaker - Speaker character ID (default 'npc')
+ * @param {boolean} preserveChoices - Keep choices visible (default false)
+ * @param {boolean} isNarrator - Narrative mode (no speaker name, special styling)
+ * @param {string|null} narratorCharacter - Character to show in narrator mode
+ */
+showDialogue(text, speaker = 'npc', preserveChoices = false, isNarrator = false, narratorCharacter = null) {
+    if (!text) return;
+    
+    // ... existing display logic ...
+    
+    // NEW: Handle narrator mode
+    if (isNarrator) {
+        // Add narrator-specific styling
+        this.elements.dialogueBox.classList.add('narrator-mode');

+                this.portraitRenderer.hidePortrait();
+            }
+        }
+    } else {
+        // Regular dialogue mode
+        this.elements.dialogueBox.classList.remove('narrator-mode');
+        this.elements.speakerName.style.display = 'block';
+        
+        // Update speaker name and portrait
+        if (this.updatePortraitForSpeaker) {
+            const characterData = this.characters?.[speaker];
+            if (characterData) {
+                this.updatePortraitForSpeaker(speaker, characterData);
+            }
+        }
+    }
+    
+    // ... rest of existing display logic ...
+}
+```
+
+### 4.2 Update displayDialogueBlocksSequentially()
+
+**Location:** `person-chat-minigame.js` - lines 751-850 (approximate)
+
+**Changes Needed:**
+- Pass `isNarrator` and `narratorCharacter` to `showDialogue()`
+- Handle narrator block rendering
+
+```javascript
+displayDialogueBlocksSequentially(blocks, originalResult, blockIndex, lineIndex = 0, accumulatedText = '') {
+    if (blockIndex >= blocks.length) {
+        // ... existing completion logic ...
+        return;
+    }
+    
+    const block = blocks[blockIndex];
+    const lines = block.text.split('\n').filter(line => line.trim());
+    
+    if (lineIndex >= lines.length) {
+        // Move to next block
+        this.displayDialogueBlocksSequentially(blocks, originalResult, blockIndex + 1, 0, '');
+        return;
+    }
+    
+    // Build accumulated text
+    const line = lines[lineIndex];
+    const newAccumulatedText = accumulatedText ? accumulatedText + '\n' + line : line;
+    
+    // UPDATED: Pass narrator info to showDialogue
+    this.ui.showDialogue(
+        newAccumulatedText,
+        block.speaker,
+        false,
+        block.isNarrator || false,
+        block.narratorCharacter || null
+    );
+    
+    // Schedule next line
+    this.scheduleDialogueAdvance(() => {
+        this.displayDialogueBlocksSequentially(blocks, originalResult, blockIndex, lineIndex + 1, newAccumulatedText);
+    }, DIALOGUE_AUTO_ADVANCE_DELAY);
+}
+```
+
+### 4.3 Add Narrator CSS Styling
+
+**Location:** `css/person-chat-minigame.css` - Add after existing classes
+
+```css
+/* Narrator mode styling */
+.person-chat-dialogue-box.narrator-mode {
+    background-color: rgba(20, 20, 20, 0.85);
+    border-color: #666;
+}
+
+.person-chat-dialogue-box.narrator-mode .person-chat-dialogue-text {
+    text-align: center;
+    font-style: italic;
+    color: #ccc;
+}
+
+/* Hide speaker name in narrator mode */
+.person-chat-dialogue-box.narrator-mode .person-chat-speaker-name {
+    display: none !important;
+}
+```
+
+**✅ Acceptance Criteria:**
+- [ ] Narrator passages display without speaker name
+- [ ] Narrator mode has distinct visual styling
+- [ ] `Narrator[npc_id]:` shows correct character portrait
+- [ ] `Narrator[]:` hides portrait entirely
+- [ ] All 20 existing showDialogue() calls still work
+- [ ] No visual regressions in existing conversations
+
+---
+
+## Phase 5: Testing & Validation
+
+### 5.1 Create Comprehensive Test Ink File
+
+**Location:** `scenarios/ink/test-line-prefix.ink`
+
+This file tests all new features with existing tag-based and new prefix-based dialogue.
+
+```ink
+VAR conversation_started = false
+
+=== start ===
+test_npc_back: Welcome to the new speaker prefix test! This uses the new format.
+Player: This looks much cleaner than tags!
+test_npc_back: I agree. Let me introduce my colleague.
+-> introduce_colleague
+
+=== introduce_colleague ===
+test_npc_front: Hi there! I'm the front desk technician.
+Player: Nice to meet you!
+Narrator: The two NPCs exchange a knowing glance.
+test_npc_back: Now that we're all acquainted...
+-> narrator_test
+
+=== narrator_test ===
+Narrator: The room falls silent for a moment.
+Narrator: Outside, birds are chirping.
+Player: That's a nice touch - narrative passages!
+test_npc_back: Glad you like it.
+-> narrator_with_character_test
+
+=== narrator_with_character_test ===
+Narrator[test_npc_back]: The technician shifts uncomfortably.
+Narrator[test_npc_front]: The other technician watches closely.
+Narrator[Player]: You sense the tension in the room.
+Narrator[]: The moment passes.
+test_npc_back: Let's move on.
+-> mixed_format_test
+
+=== mixed_format_test ===
+# speaker:npc:test_npc_front
+This line uses the old tag-based format (still works).
+# speaker:player
+And this one too - tags still work!
+test_npc_back: But I'm back to using the new prefix format.
+-> npc_behavior_tags_test
+
+=== npc_behavior_tags_test ===
+test_npc_back: Let me demonstrate the NPC behavior tag enhancements.
+Player: What can they do now?
+test_npc_back: I can affect myself without specifying my ID.
+# hostile
+test_npc_back: I'm hostile now! (No ID parameter needed)
+# friendly
+test_npc_back: And now I'm friendly again.
+Player: What about multiple NPCs?
+test_npc_front: We can both be affected at once.
+# hostile:test_npc_back,test_npc_front
+test_npc_back: Both of us are now hostile!
+test_npc_front: Using a comma-separated list.
+# friendly:test_npc_*
+test_npc_back: And now we're both friendly via wildcard pattern.
+Player: Impressive!
+-> edge_cases_test
+
+=== edge_cases_test ===
+Player: Let's test some edge cases.
+test_npc_back: Sure thing.
+Narrator[]: No character shown here.
+Player: What about empty narrator?
+test_npc_back: Just tested it.
+Player: And what about very long dialogue? Well, let's see what happens when a dialogue line is very long and goes on for many words to test whether the rendering system can handle significantly longer text without breaking or causing performance issues.
+test_npc_back: All good!
+-> stress_test
+
+=== stress_test ===
+// Multiple speakers in rapid succession
+test_npc_back: First speaker.
+test_npc_front: Second speaker.
+Player: Third speaker.
+test_npc_back: Back to first.
+test_npc_front: Back to second.
+Player: Back to third.
+-> end
+
+=== end ===
+test_npc_front: Thanks for testing!
+Player: This is going to make writing conversations much easier!
+Narrator: And scene.
+-> END
+```

+```
+
+**✅ Acceptance Criteria:**
+- [ ] Empty parameter defaults to main NPC
+- [ ] Single NPC ID works
+- [ ] Comma-separated list works
+- [ ] Wildcard patterns work

+# Person-Chat Minigame: Line Prefix Speaker Format (Revised)
+
+## Date
+November 23, 2025
+
+## Executive Summary
+
+This document describes improvements to the person-chat minigame enabling cleaner per-line speaker specification using a natural dialogue prefix format (`Speaker: Text`). The design maintains 100% backward compatibility with existing tag-based conversations while providing significant quality-of-life improvements for content creators.
+
+**Key Goals:**
+1. ✅ Make multi-NPC conversations more readable and easier to write
+2. ✅ Add native narrator/narrative passage support
+3. ✅ Maintain full backward compatibility with existing content
+4. ✅ Minimize performance impact
+5. ✅ Improve code maintainability through refactoring
+
+---
+
+## Current System
+
+### Tag-Based Speaker Detection
+
+The current system uses Ink tags to specify speakers. Example from existing conversation:
+
+```ink
+=== colleague_introduction ===
+# speaker:npc:test_npc_front
+Nice to meet you! I'm the lead technician here.
+-> player_question
+
+=== player_question ===
+# speaker:player
+What kind of work do you both do here?
+-> response
+```
+
+### How It Works
+- **Tags Applied Per Knot:** Speaker tags mark the start of each Ink knot/stitch
+- **Block-Level:** Tags apply to all text until the next tag is encountered  
+- **Mixed Concerns:** Speaker tags coexist with game action tags (`# unlock_door:ceo`)
+- **Speaker Detection:** `determineSpeaker()` method parses tags to find the most recent speaker tag
+- **Defaults to Main NPC:** When no tags present, conversation defaults to the initiating NPC
+
+### Supported Formats
+- `# speaker:player` → Player character
+- `# speaker:npc` → Main NPC (conversation initiator)
+- `# speaker:npc:test_npc_back` → Specific NPC by ID
+- `# player` → Shorthand for player
+- `# npc` → Shorthand for main NPC
+
+### Current Limitations
+1. **Verbose for multi-speaker scenes** - Each speaker change requires a new knot/stitch with tag
+2. **Mixed concerns** - Speaker identification mixed with game actions in tag system
+3. **Not line-granular** - Difficult to have multiple speakers within a single knot
+4. **No narrator support** - No dedicated way to write narrative-only passages
+5. **Writer burden** - Authors must remember to add tags for every speaker change
+6. **Maintenance issue** - `determineSpeaker()` method exists but isn't used; speaker detection is hardcoded in another function
+
+---
+
+## Proposed Solution: Line Prefix Format
+
+### Core Concept
+
+Parse each dialogue line for an optional `SPEAKER_ID: Text` prefix, enabling per-line speaker specification without requiring new Ink knots.
+
+### Syntax
+
+#### Basic Format
+```
+SPEAKER_ID: Dialogue text here
+```
+
+#### Examples
+
+**Multi-NPC Conversation:**
+```ink
+=== group_meeting ===
+test_npc_back: Agent, meet my colleague from the back office.
+test_npc_front: Nice to meet you! I'm the lead technician here.
+Player: What kind of work do you both do here?
+test_npc_back: Well, I handle the front desk operations...
+test_npc_front: I manage all the backend systems.
+```
+
+**Natural Speaker Changes:**
+```ink
+=== tense_moment ===
+test_npc_back: I have something important to tell you.
+Narrator: An awkward silence fills the room.
+Player: What is it?
+test_npc_back: The secure system has been compromised.
+```
+
+**Narrator with Character Portrait:**
+```ink
+=== character_focus ===
+Narrator[test_npc_back]: The technician looks nervous as footsteps approach.
+Narrator[]: The hallway falls silent.
+Narrator[Player]: You feel a knot forming in your stomach.
+```
+
+**Shorthand for Main NPC:**
+```ink
+=== simple_chat ===
+npc: Hey there! How can I help?
+Player: I need some information.
+npc: Sure, what do you need to know?
+```
+
+**Lines Without Prefix Inherit Previous Speaker:**
+```ink
+=== multi_line ===
+test_npc_back: This is the first line from this speaker.
+This line continues without a prefix, so it's still from test_npc_back.
+test_npc_front: Now the speaker changes.
+This is also from test_npc_front.
+```
+
+### Key Design Decisions
+
+1. **Speaker ID Validation:** Speaker IDs must match existing characters or special keywords ('player', 'npc', 'narrator'). Invalid IDs are rejected - line is treated as unprefixed.
+
+2. **Empty Text Rejection:** Lines like `"Player: "` (with empty text after colon) are rejected as invalid prefixes - treated as unprefixed lines.
+
+3. **First Colon Only:** Multiple colons in dialogue don't break parsing. Example: `"Player: What time is it: 5pm?"` → speaker='player', text='What time is it: 5pm?'
+
+4. **Case-Insensitive:** Speaker IDs normalize to lowercase for lookup. `"Player:"`, `"player:"`, `"PLAYER:"` all work identically.
+
+5. **Prefix Priority:** If a line has a valid prefix, it takes priority over any tags. This allows mixing old and new formats safely.
+
+6. **Default Speaker:** Lines without prefixes inherit the previous speaker. The first line without a prefix uses tag-based or default speaker (main NPC).
+
+7. **Narrator Variants:**
+   - `Narrator: Text` → Narrative passage, no portrait, centered styling
+   - `Narrator[npc_id]: Text` → Narrative with specific character's portrait visible
+   - `Narrator[]: Text` → Narrative explicitly with no portrait (same as basic)
+
+### Parsing Logic
+
+```
+For each dialogue line:
+  ↓
+  1. Check for Narrator[character]: pattern → narrative with optional character
+  2. Check for SPEAKER_ID: pattern → speaker detected
+  3. If match found and speaker exists in character index → valid prefix
+  4. If no match found or speaker doesn't exist → no prefix (unprefixed line)
+  ↓
+  If prefixed: Use parsed speaker and text
+  If unprefixed:
+    - If previous speaker exists: continue with that speaker
+    - If no previous speaker: use tag-based or default (main NPC)
+```
+
+### Key Advantages
+
+✅ **Natural Readability** - Ink source looks like screenplay/dialogue format  
+✅ **Per-Line Granularity** - Change speaker every line without new knots  
+✅ **100% Backward Compatible** - All existing tag-based conversations work unchanged  
+✅ **Separation of Concerns** - Speaker identification in text, game actions in tags  
+✅ **Narrator Support** - Native way to write narrative passages  
+✅ **Intuitive for Writers** - Natural dialogue format, minimal learning curve  
+✅ **Multi-NPC Friendly** - Perfect for group conversations  
+✅ **Code Maintainability** - Enables refactoring to consolidate speaker detection  
+
+### Integration with Existing Systems
+
+**Tags Remain for Actions:**
+```ink
+=== unlocking_door ===
+helper_npc: I can help you with that door.
+# unlock_door:ceo
+helper_npc: There you go! It's open now.
+Player: Thanks!
+```
+
+**Choice Display Unchanged:**
+```ink
+=== decision_point ===
+test_npc_back: What would you like to do?
++ [Ask about the mission] → ask_mission
++ [Leave] → leave
+```
+
+**State Variables Still Work:**
+```ink
+VAR has_keycard = false
+
+=== check_keycard ===
+{has_keycard:
+  Player: I have the keycard now.
+  npc: Great! You can access the secure area.
+- else:
+  Player: I need to find a keycard.
+  npc: Check the security office.
+}
+```
+
+---
+
+## NPC Behavior Tag Enhancements
+
+### Current Limitation
+
+Behavior tags (like `# hostile:npc_id`) currently require explicit NPC IDs:
+
+```ink
+test_npc_back: You shouldn't have done that.
+# hostile:test_npc_back
+```
+
+### Proposed Improvements
+
+#### 1. Default to Main NPC (No ID Required)
+```ink
+test_npc_back: You shouldn't have done that.
+# hostile
+// Automatically affects test_npc_back (main conversation NPC)
+```
+
+#### 2. Multiple NPCs (Comma-Separated)
+```ink
+# hostile:guard_1,guard_2,guard_3
+// All three guards become hostile
+```
+
+#### 3. Wildcard Patterns
+```ink
+# hostile:guard_*
+// All NPCs with IDs starting with "guard_"
+
+# friendly:receptionist_*,manager_*
+// All receptionists and managers become friendly
+
+# hostile:all
+// Every NPC in current room
+```
+
+### Affected Tags
+These behavior tags will support new formats:
+- `hostile` - Make NPC(s) aggressive
+- `friendly` - Make NPC(s) non-aggressive
+- `influence` - Modify relationship with NPC(s)
+- `suspicious` - Make NPC(s) wary
+- Any future behavior-modifying tags
+
+---
+
+## Migration Guide
+
+### For Existing Conversations
+**No changes required.** All existing Ink files using tag-based speaker detection work exactly as before.
+
+### For New Conversations
+Writers can choose:
+1. **Pure prefix format** (recommended for new content) - cleaner, more readable
+2. **Pure tag format** (consistency with old content) - works fine
+3. **Mixed format** (prefixes for speakers, tags for actions) - flexible approach
+
+### Example Migration
+
+**Before (Tags):**
+```ink
+=== conversation ===
+# speaker:npc:test_npc_back
+Welcome to the office.
+-> next_part
+
+=== next_part ===
+# speaker:player
+Thanks for having me.
+-> response
+
+=== response ===
+# speaker:npc:test_npc_back
+Let me show you around.
+-> END
+```
+
+**After (Prefixes):**
+```ink
+=== conversation ===
+test_npc_back: Welcome to the office.
+Player: Thanks for having me.
+test_npc_back: Let me show you around.
+-> END
+```
+
+---
+
+## Technical Considerations
+
+### Performance
+- **Line-by-line parsing:** Single regex check per line
+- **Minimal overhead:** ~1ms for typical conversations (10-100 lines)
+- **Cached speakers:** Current speaker tracked to avoid re-lookup
+- **Lazy evaluation:** Only parse when dialogue text present
+
+### Edge Cases Handled
+1. **Colons in dialogue:** `Player: What time is it: 5pm?` → correctly parsed
+2. **Empty lines:** Ignored/stripped before processing
+3. **Multiline blocks:** Lines without prefix inherit current speaker
+4. **Invalid speaker IDs:** Treated as unprefixed, no error
+5. **Unknown characters:** Gracefully rejected, line treated as unprefixed
+6. **Case sensitivity:** All speaker IDs normalized to lowercase for comparison
+
+### Resource Considerations
+- **Memory:** Minimal - no persistent data structures added
+- **Parsing complexity:** O(n) where n = number of lines (expected)
+- **Character lookup:** O(1) using hash map (characters index)
+
+### Compatibility
+- **Ink Compiler:** No changes needed (prefixes are just text)
+- **inkjs Runtime:** No changes needed  
+- **Existing Stories:** 100% backward compatible
+- **Rails Backend:** No changes needed (serves pre-compiled JSON)
+- **All 20 showDialogue() call sites:** Work unchanged with optional parameters
+
+---
+
+## Technical Limitations
+
+1. **Speaker ID Format:** Must match regex `[A-Za-z_][A-Za-z0-9_]*` - no special characters allowed
+2. **Maximum Line Length:** No hard limit, but performance degrades for 10,000+ character lines
+3. **Narrator Character Validity:** Character must exist in current room context to display portrait
+4. **Pattern Matching:** Simple wildcard support (`*` only), not full regex
+5. **Room Context:** NPC behavior tags requiring room lookup depend on `window.currentRoom` being set
+
+---
+
+## Success Criteria
+
+Implementation is successful when:
+
+1. ✅ Existing tag-based conversations work without modification
+2. ✅ New prefix-based conversations parse correctly
+3. ✅ Speaker changes mid-dialogue block work smoothly
+4. ✅ Narrator passages display correctly (no speaker name, special styling)
+5. ✅ `Narrator[character]:` shows correct character portrait
+6. ✅ Multi-NPC conversations (like test.ink) display perfectly
+7. ✅ Performance remains acceptable (< 1ms per line parse)
+8. ✅ All code comments updated with explanations
+9. ✅ Writer guide created and tested
+10. ✅ Zero regression in existing conversations
+
+---
+
+## Future Enhancements
+
+### Emotion Variants
+```ink
+test_npc_back[angry]: I can't believe you did that!
+test_npc_back[happy]: But I'm glad it worked out.
+```
+
+### Location Hints  
+```ink
+test_npc_back@lab: Let me show you the equipment here.
+```
+
+### Sound Effects Inline
+```ink
+Sound[door_slam.mp3]: The door slams shut.
+test_npc_back: What was that?!
+```
+
+### Background Changes
+```ink
+Background[office_night.png]: The lights dim as evening falls.
+test_npc_back: See? Everything changes at night.
+```
+

+
+## Conclusion
+
+The proposed line prefix format provides significant quality-of-life improvements for content creators while maintaining complete backward compatibility and minimal performance impact. The feature is additive rather than replacement - existing content works unchanged, and new content can opt into the cleaner syntax.
+
+The architectural refactoring (Phase 0) consolidates scattered speaker detection logic into a single `determineSpeaker()` method, improving maintainability and making it easier to add future speaker detection features.

+# Quick Reference: Line Prefix Speaker Format & Enhancements
+## Ink Writer Cheat Sheet (Revised)
+
+---
+
+## Line Prefix Syntax
+
+### Basic Speaker Prefix
+```
+SPEAKER_ID: Dialogue text
+```
+
+### Valid Speaker IDs
+- `Player` - Player character (case-insensitive)
+- `npc` - Main conversation NPC (shorthand)
+- `test_npc_back` - Specific NPC by ID
+- `Narrator` - Narrative passage (no portrait)
+
+### Examples
+
+**Player:**
+```ink
+Player: I need to investigate this room.
+```
+
+**Specific NPC:**
+```ink
+test_npc_back: Let me help you with that.
+```
+
+**Main NPC Shorthand:**
+```ink
+npc: This refers to whoever you're talking to.
+```
+
+**No Prefix (Defaults to Current Speaker):**
+```ink
+=== greeting ===
+Hello there! // Uses main NPC from previous context
+Player: Hi!
+What brings you here? // Also uses main NPC (speaker continuity)
+```
+
+---
+
+## Narrator Syntax
+
+### Basic Narrator (No Portrait)
+```ink
+Narrator: The room falls silent.
+Narrator: Outside, rain begins to fall.
+```
+
+### Narrator with Character in View
+Show narrative text while keeping a specific character's portrait visible:
+
+```ink
+Narrator[test_npc_back]: The technician shifts nervously.
+Narrator[Player]: You feel a sense of dread.
+Narrator[security_guard]: The guard's hand moves toward his weapon.
+```
+
+### Narrator with Explicit No Portrait
+```ink
+Narrator[]: The hallway is completely empty.
+```
+
+### When to Use Each
+- `Narrator:` - Default, no portrait (scene descriptions)
+- `Narrator[character]:` - Focus on specific character during narration
+- `Narrator[]` - Explicitly empty scene (same as `Narrator:`, more clear)
+
+---
+
+## NPC Behavior Tags
+
+### Syntax
+```
+# BEHAVIOR_TAG:TARGET_SPEC
+```
+
+### Target Specifications
+
+#### No Target (Main NPC Only)
+```ink
+test_npc_back: You betrayed me!
+# hostile
+// Makes test_npc_back hostile (automatically uses main NPC)
+```
+
+#### Single NPC
+```ink
+# hostile:security_guard
+// Makes security_guard hostile
+```
+
+#### Multiple NPCs (Comma-Separated)
+```ink
+# hostile:guard_1,guard_2,guard_3
+// All three guards become hostile
+```
+
+#### Wildcard Pattern
+```ink
+# hostile:guard_*
+// All NPCs with IDs starting with "guard_"
+
+# hostile:scientist_*,engineer_*
+// Multiple patterns supported (scientist_* OR engineer_*)
+```
+
+#### All NPCs in Room
+```ink
+# hostile:all
+// Every NPC in the current room
+```
+
+### Behavior Tags
+
+**`hostile`** - Make NPC(s) aggressive/hostile
+```ink
+# hostile
+# hostile:npc_id
+# hostile:npc1,npc2
+# hostile:pattern_*
+# hostile:all
+```
+
+**`friendly`** - Make NPC(s) non-aggressive/friendly
+```ink
+# friendly
+# friendly:npc_id
+# friendly:guard_*
+```
+
+**`influence`** - Modify relationship score
+```ink
+# influence::+10              // Main NPC +10 relationship
+# influence:npc_id:+10        // Specific NPC +10
+# influence:npc_id:-20        // Specific NPC -20
+# influence:receptionist_*:+15 // All receptionists +15
+```
+
+---
+
+## Complete Examples
+
+### Multi-Character Conversation with Narrator
+```ink
+=== tense_standoff ===
+test_npc_back: We need to talk about what you did.
+Narrator[test_npc_back]: His hand trembles slightly.
+Player: I can explain.
+Narrator[Player]: You feel the weight of their stares.
+test_npc_front: Make it quick.
+Narrator: The room holds its breath.
+```
+
+### Group Behavior Change
+```ink
+=== alarm_triggered ===
+security_guard: INTRUDER ALERT!
+Narrator: Klaxons blare throughout the facility.
+# hostile:guard_*
+Narrator[Player]: Every guard in the building is now hunting you.
+Player: Time to run!
+```
+
+### Conditional Behavior
+```ink
+VAR insulted_scientists = false
+
+=== lab_entrance ===
+{insulted_scientists:
+    lead_scientist: You're not welcome here anymore.
+    # hostile:scientist_*
+    Narrator: The entire research team glares at you.
+- else:
+    lead_scientist: Welcome to the lab!
+    # friendly:scientist_*
+    Narrator: The scientists smile warmly.
+}
+```
+
+### Mixed Format (Old Tags + New Prefixes)
+```ink
+=== old_and_new ===
+# speaker:npc:test_npc_back
+This line uses old tag-based format.
+test_npc_back: This line uses new prefix format.
+# unlock_door:ceo
+test_npc_back: The door is now unlocked!
+# hostile:security_*
+Narrator[test_npc_back]: He realizes the alarm will trigger soon.
+Player: We need to hurry!
+```
+
+### Speaker Continuity
+```ink
+=== continuity_test ===
+test_npc_back: This is line one from this speaker.
+This is line two, still from test_npc_back (no prefix needed).
+Line three also continues with test_npc_back.
+Player: Now the speaker changes.
+This is from the player.
+test_npc_back: Back to the technician.
+```
+
+### First Line Without Prefix
+```ink
+=== default_speaker ===
+// First line with no prefix - uses main NPC (test_npc_back in this context)
+Let me help you understand the system.
+test_npc_front: I'm here too!
+Player: Thanks both of you.
+// Now without prefix - uses most recent (Player, from previous line)
+I really appreciate this.
+```
+
+---
+
+## Best Practices
+
+### ✅ DO
+
+**Use prefixes for speaker clarity:**
+```ink
+test_npc_back: I'm the back office technician.
+test_npc_front: And I'm the front desk technician.
+Player: Nice to meet you both!
+```
+
+**Use narrator for scene descriptions:**
+```ink
+Narrator: Thunder rumbles in the distance.
+Narrator: The lights flicker ominously.
+```
+
+**Use narrator with character for dramatic focus:**
+```ink
+Narrator[villain]: A cruel smile crosses their face.
+```
+
+**Use default speaker for simple conversations:**
+```ink
+=== simple_chat ===
+Hey there, need some help? // Main NPC
+Player: Yes, please!
+What do you need? // Main NPC (no prefix needed)
+```
+
+**Use behavior tag enhancements for groups:**
+```ink
+# hostile:all         // Simple and clear - affects whole room
+# hostile:guard_1,guard_2,guard_3  // Explicit control - specific NPCs
+# hostile:guard_*     // Pattern for flexibility - any NPC starting with "guard_"
+```
+
+**Leverage speaker continuity:**
+```ink
+=== efficient_dialogue ===
+test_npc_back: I need to tell you something important.
+It involves security and it can't wait.
+The situation is getting worse.
+// No need to repeat "test_npc_back:" for each line!
+```
+
+### ❌ DON'T
+
+**Don't mix speaker prefix with speaker tag (redundant):**
+```ink
+# speaker:player
+Player: This is redundant and confusing
+```
+
+**Don't use narrator for dialogue:**
+```ink
+// Wrong:
+Narrator: "Hello," says the guard.
+
+// Correct:
+security_guard: Hello.
+```
+
+**Don't forget the space after colon:**
+```ink
+// Wrong:
+Player:Hello!
+
+// Correct:
+Player: Hello!
+```
+
+**Don't use speaker ID that doesn't exist:**
+```ink
+// Wrong - nonexistent_npc doesn't exist:
+nonexistent_npc: This won't work!
+
+// Correct - use actual NPC ID:
+test_npc_back: This will work.
+```
+
+**Don't rely on empty text after prefix:**
+```ink
+// This won't work:
+Player:    (empty dialogue after colon)
+
+// These work:
+Player: Hello!
+Hello!  (unprefixed, uses current speaker)
+```
+
+---
+
+## Troubleshooting
+
+### Speaker Not Showing/Changing
+
+**Check for:**
+1. Spelling of speaker ID (case-insensitive but must be exact otherwise)
+2. NPC exists in current room
+3. Space after colon: `Speaker: Text` (not `Speaker:Text`)
+4. Console warnings about speaker not found
+
+**Example Debug:**
+```
+❌ "test_npc_bak: Hello!" 
+   (typo: should be "test_npc_back")
+
+✅ "test_npc_back: Hello!"
+```
+
+### Narrator Not Showing/Wrong Character
+
+**Check for:**
+1. Character ID spelling exactly matches NPC ID
+2. Character exists in current room (for Narrator[id]:)
+3. Using correct syntax: `Narrator[character_id]:` not `Narrator(character_id):`
+
+**Example Debug:**
+```
+❌ "Narrator[test_npc_Back]: Text"
+   (case mismatch with actual ID: test_npc_back)
+
+✅ "Narrator[test_npc_back]: Text"
+```
+
+### Behavior Tag Not Working
+
+**Check for:**
+1. NPC ID is correct (typos won't error, just won't match)
+2. NPC exists in current room (for pattern matching and "all")
+3. Wildcard pattern is correct (only * for any characters)
+4. Using supported behavior tags (hostile, friendly, influence, suspicious)
+
+**Example Debug:**
+```
+❌ "# hostile:guard_"
+   (no wildcard - would need: guard_* to match multiple)
+
+✅ "# hostile:guard_*"
+   (matches: guard_1, guard_2, guard_front, etc.)
+```
+
+### Empty Line After Prefix
+
+**Problem:**
+```ink
+Player: 
+// Empty text after colon - won't be recognized as prefix
+```
+
+**Solution:**
+If you want empty dialogue, use unprefixed:
+```ink
+Player: (Silence)  // Has content
+
+// or just:
+(Just use narrative description)
+```
+
+---
+
+## Migration from Old Format
+
+### Before (Tag-Based, 3 Knots)
+```ink
+=== conversation ===
+# speaker:npc:test_npc_back
+Welcome!
+
+=== conversation_cont ===
+# speaker:player
+Hello!
+
+=== conversation_response ===
+# speaker:npc:test_npc_back
+How can I help?
+```
+
+### After (Prefix-Based, 1 Knot)
+```ink
+=== conversation ===
+test_npc_back: Welcome!
+Player: Hello!
+test_npc_back: How can I help?
+```
+
+### Comparison
+| Aspect | Old Format | New Format |
+|--------|-----------|-----------|
+| Readability | Verbose, spread across knots | Natural screenplay format |
+| Lines Written | 3 knots + 3 tags + 3 dialogue | 1 knot + 3 dialogue |
+| Speaker Changes | Requires new knot | Just add next line |
+| Learning Curve | Moderate | Intuitive |
+| Backward Compatible | N/A | Yes! ✅ |
+
+---
+
+## Version & Compatibility
+
+✅ **Backward Compatible** - All existing Ink files work unchanged  
+✅ **Forward Compatible** - New features work with existing system  
+✅ **Mix and Match** - Can use old and new syntax together  
+✅ **No Writer Retraining** - New format is optional  
+✅ **No Content Migration** - Existing conversations work as-is  
+
+---
+
+## Quick Syntax Reference
+
+| Format | Usage | Example |
+|--------|-------|---------|
+| `Speaker: Text` | Standard dialogue | `Player: Hello!` |
+| `npc: Text` | Main NPC shorthand | `npc: How can I help?` |
+| `Narrator: Text` | Narrative, no portrait | `Narrator: The door slams.` |
+| `Narrator[id]: Text` | Narrative with character | `Narrator[npc_back]: He nods.` |
+| `Narrator[]: Text` | Narrative, explicit no portrait | `Narrator[]: Silence.` |
+| `# hostile` | Main NPC hostile | `# hostile` |
+| `# hostile:id` | Single NPC hostile | `# hostile:guard_1` |
+| `# hostile:id1,id2` | Multiple NPCs | `# hostile:guard_1,guard_2` |
+| `# hostile:pattern_*` | Pattern match | `# hostile:guard_*` |
+| `# hostile:all` | All in room | `# hostile:all` |

+
+---
+
+## Key Improvements Over Original Plan
+
+### 1. Phase 0: Pre-Implementation Refactoring
+**New in Revised Plan**
+
+The original plan didn't address the core architectural issue: `determineSpeaker()` exists but isn't used. Phase 0 is critical pre-work:
+- Consolidates speaker detection into single method
+- Fixes memory leak in UI component
+- Adds state locking for race conditions
+- Foundation for all subsequent phases
+- 2-3 hours well spent upfront
+
+### 2. Enhanced Security Review
+**Expanded in Revised Plan**
+
+Original plan had basic NPC pattern matching. Revised plan adds:
+- Comprehensive input sanitization
+- Regex injection attack prevention
+- Try/catch error handling
+- Invalid NPC handling with graceful fallback
+- Console logging for debugging
+
+### 3. Comprehensive Edge Case Handling
+**Detailed in Revised Plan**
+
+- Empty text validation
+- Case-insensitive speaker IDs
+- Malformed prefix rejection
+- Unicode character support (documented)
+- Very long line handling (documented)
+- Invalid speaker ID graceful rejection
+- Memory leak prevention
+
+### 4. Backward Compatibility Proof
+**Emphasized in Revised Plan**
+
+- All method signatures use optional parameters only
+- No breaking changes to existing APIs
+- 20+ existing call sites verified to work unchanged
+- Tag-based fallback always available
+- Mixed format (old+new) explicitly supported
+
+### 5. Clear Implementation Path
+**Structured in Revised Plan**
+
+- Phase 0: Pre-work (consolidation)
+- Phases 1-4: Core features
+- Phase 5: Comprehensive testing with 30+ test cases
+- Phase 6: Behavior tag enhancements
+- Phase 7: Documentation
+- Realistic timeline: 14-21 hours total
+
+### 6. Writer-Focused Documentation
+**Enhanced in Revised Plan**
+
+- QUICK_REFERENCE_REVISED.md is production-ready
+- Includes do/don't best practices
+- Comprehensive troubleshooting guide
+- Migration guide for old format
+- Before/after examples for clarity
+
+---

+# Implementation Plan: Line Prefix Speaker Format
+## Actionable Development Guide
+
+**Target Files:**
+- `public/break_escape/js/minigames/person-chat/person-chat-minigame.js`
+- `public/break_escape/js/minigames/person-chat/person-chat-ui.js`
+- `public/break_escape/css/person-chat-minigame.css`
+- `public/break_escape/js/minigames/helpers/chat-helpers.js`
+
+**Critical Implementation Notes:**
+1. **`determineSpeaker()` is currently unused** - The codebase has this method but doesn't call it. Speaker detection is hardcoded in `createDialogueBlocks()` (line 699). Phase 0 must refactor this.
+2. **Function naming** - This plan calls the function `buildDialogueBlocks()` but the codebase has `createDialogueBlocks()`. Use the existing name to minimize breaking changes.
+3. **Backward compatibility** - All method signatures use optional parameters with sensible defaults to maintain existing API.
+4. **Performance** - Line-by-line parsing adds minimal overhead (~1ms for typical conversations). Caching is not needed initially.
+
+---
+
+## Phase 0: Pre-Implementation Refactoring (NEW)
+
+### 0.1 Consolidate Speaker Detection Logic
+
+**Goal:** Make `determineSpeaker()` the single source of truth for speaker detection
+
+**Current State:**
+- `determineSpeaker()` exists but is never called (lines 500-543)
+- Speaker detection is hardcoded inline in `createDialogueBlocks()` (line 699)
+- This inconsistency will cause maintenance issues
+
+**Changes Required:**
+
+1. **In `createDialogueBlocks()` - Replace inline detection with call to `determineSpeaker()`:**
+
+```javascript
+// OLD CODE (line 699):
+let speaker = this.npc.id;
+if (tag.includes('speaker:player')) {
+    speaker = 'player';
+} else if (tag.includes('speaker:npc:')) {
+    // Extract NPC ID...
+}
+
+// NEW CODE:
+// First pass through new logic below, then:
+const speaker = this.determineSpeaker(result);
+```
+
+2. **Add state locking to prevent race conditions:**
+
+```javascript
+// Add to constructor:
+this.isProcessingDialogue = false;
+
+// Add to displayAccumulatedDialogue():
+if (this.isProcessingDialogue) {
+    console.log('⏳ Already processing dialogue, ignoring');
+    return;
+}
+this.isProcessingDialogue = true;
+// ... process dialogue ...
+this.isProcessingDialogue = false;
+```
+
+3. **Fix memory leak in PersonChatUI:**
+
+```javascript
+// In destroy() or conversation end handler:
+destroy() {
+    if (this.charactersWithParallax) {
+        this.charactersWithParallax.clear();
+    }
+    // ... other cleanup ...
+}
+```
+
+**✅ TODO:**
+- [ ] Refactor `createDialogueBlocks()` to call `determineSpeaker()` instead of inline logic
+- [ ] Add dialogue processing state lock
+- [ ] Add cleanup for `charactersWithParallax` Set
+- [ ] Verify all existing conversations still work after refactoring
+- [ ] No API changes - this is purely internal consolidation
+
+---
+
+## Phase 1: Core Parsing Function
+
+### 1.1 Add parseDialogueLine() Utility
+
+**Location:** `person-chat-minigame.js` (add as new method after `determineSpeaker()`)
+
+**Design Notes:**
+- Handles edge cases: empty text after colon, malformed prefixes, Unicode
+- Case-insensitive for speaker IDs ("Player", "player", "PLAYER" all normalize to "player")
+- Validates speaker IDs exist before accepting them as prefixes
+- Returns consistent object structure for all inputs
+
+```javascript
+/**
+ * Parse a dialogue line for speaker prefix format
+ * Format: "SPEAKER_ID: Dialogue text here"
+ * 
+ * Examples:
+ * - "test_npc_back: Hello there!" → { speaker: 'test_npc_back', text: 'Hello there!', hasPrefix: true }
+ * - "Player: What's going on?" → { speaker: 'player', text: "What's going on?", hasPrefix: true }
+ * - "Narrator: The room falls silent." → { speaker: 'narrator', text: 'The room falls silent.', hasPrefix: true, isNarrator: true, narratorCharacter: null }
+ * - "Narrator[test_npc]: She looks worried." → { speaker: 'narrator', text: 'She looks worried.', hasPrefix: true, isNarrator: true, narratorCharacter: 'test_npc' }
+ * - "Narrator[]: The hallway is empty." → { speaker: 'narrator', text: 'The hallway is empty.', hasPrefix: true, isNarrator: true, narratorCharacter: null }
+ * - "Just regular text" → { speaker: null, text: 'Just regular text', hasPrefix: false }
+ * - "Player: " (empty text) → { speaker: null, text: 'Player: ', hasPrefix: false } (ignored - not valid)
+ * - "Player: Text with: multiple: colons" → { speaker: 'player', text: 'Text with: multiple: colons', hasPrefix: true } (first colon only)
+ * 
+ * @param {string} line - Single line of dialogue text
+ * @returns {Object} Parsed result with speaker, text, hasPrefix, isNarrator, narratorCharacter

+
+### 5.2 Test Cases Checklist
+
+**Backward Compatibility Tests:**
+- [ ] Existing tag-based conversations (helper-npc.json, neye-eve.json, etc.) work unchanged
+- [ ] Tag-based speaker detection still functions
+- [ ] Mixed tag + prefix format works
+
+**Prefix Format Tests:**
+- [ ] Single-speaker prefix conversation works
+- [ ] Multi-speaker conversation (test.ink style) works
+- [ ] Speaker changes mid-block work smoothly
+- [ ] "Player:" prefix works (case-insensitive)
+- [ ] "npc:" shorthand works
+- [ ] Specific NPC IDs work (test_npc_back, test_npc_front)
+
+**Narrator Tests:**
+- [ ] "Narrator:" prefix detected
+- [ ] Narrator text displays without portrait
+- [ ] Narrator styling (italic, centered) applied
+- [ ] Narrator mixed with character dialogue works
+
+**Edge Cases:**
+- [ ] Empty lines ignored
+- [ ] Lines without prefix inherit current speaker
+- [ ] Invalid speaker IDs fall back gracefully
+- [ ] Colons in dialogue text don't break parsing
+- [ ] Multi-line dialogue blocks work
+
+**UI Tests:**
+- [ ] Portrait changes when speaker changes
+- [ ] Speaker name updates correctly
+- [ ] Narrator mode hides portrait correctly
+- [ ] Auto-advance timing works
+- [ ] Click-through mode works
+- [ ] Choice display works after multi-speaker dialogue

+## Phase 6: NPC Behavior Tag Enhancements
+
+### 6.1 Update processGameActionTags() in chat-helpers.js
+
+**Location:** `js/minigames/helpers/chat-helpers.js` (around line 220)
+
+**Goal:** Allow behavior tags to work without explicit NPC IDs, support multiple NPCs, and pattern matching
+
+**New Helper Function:**
+```javascript
+/**
+ * Parse NPC target specification from tag parameter
+ * Supports:
+ * - Empty/null → Main conversation NPC
+ * - Single ID → That specific NPC
+ * - Comma-separated list → Multiple NPCs
+ * - Wildcard pattern → Pattern matching (guard_*, all)
+ * 
+ * @param {string|null} param - Tag parameter
+ * @param {string} mainNpcId - Main conversation NPC ID (fallback)
+ * @param {string} currentRoomId - Current room ID for "all" pattern
+ * @returns {Array<string>} Array of NPC IDs to affect
+ */
+function parseNPCTargets(param, mainNpcId, currentRoomId) {
+    // No parameter - default to main NPC
+    if (!param || param.trim() === '') {
+        console.log(`🎯 NPC target: main conversation NPC (${mainNpcId})`);
+        return [mainNpcId];
+    }

+    
+    // Check for "all" keyword
+    if (trimmed.toLowerCase() === 'all') {
+        console.log(`🎯 NPC target: ALL in room ${currentRoomId}`);
+        return getAllNPCsInRoom(currentRoomId);
+    }
+    
+    // Check for wildcard pattern (contains *)
+    if (trimmed.includes('*')) {
+        console.log(`🎯 NPC target: pattern "${trimmed}"`);
+        return getNPCsByPattern(trimmed, currentRoomId);
+    }

+        console.log(`🎯 NPC targets: list [${npcIds.join(', ')}]`);
+        return npcIds;
+    }
+

+    return room.npcs.map(npc => npc.id);
+}
+
+/**
+ * Get NPC IDs matching a wildcard pattern
+ * @param {string} pattern - Pattern with * wildcard (e.g., "guard_*")
+ * @param {string} roomId - Room ID to search (optional, searches all if not provided)
+ * @returns {Array<string>} Array of matching NPC IDs
+ */
+function getNPCsByPattern(pattern, roomId = null) {
+    // Convert wildcard pattern to regex
+    // guard_* → /^guard_.*$/

+}
+```
+
+**Updated hostile tag handler:**

+        // Parse NPC targets (supports empty, single, list, patterns)
+        const mainNpcId = window.currentConversationNPCId;

+                }
+            }
+            
+            result.success = true;
+            result.message = successCount === 1 
+                ? `⚠️ ${npcIds[0]} is now hostile!`
+                : `⚠️ ${successCount} NPCs are now hostile!`;
+            
+            if (ui) ui.showNotification(result.message, 'warning');
+        } else {

+            console.warn(result.message);
+        }
+    }
+    break;
+```

+
+## Phase 7: Documentation
+
+### 7.1 Update Ink Writer Guide
+
+**Create:** `docs/INK_SPEAKER_PREFIX_GUIDE.md`
+
+**Content:**
+```markdown
+# Ink Speaker Prefix Guide
+
+## Overview
+You can now specify speakers using a clean prefix format at the start of dialogue lines.
+
+## Syntax
+
+### Basic Format
+```
+SPEAKER_ID: Dialogue text here
+```
+
+### Examples
+
+**Player Dialogue:**
+```ink
+Player: I need to find the keycard.
+```
+
+**NPC Dialogue:**
+```ink
+test_npc_back: I can help you with that.
+```
+
+**Multiple NPCs:**
+```ink
+test_npc_back: Let me introduce my colleague.
+test_npc_front: Hello! I handle the security systems.
+Player: Nice to meet you both!
+```
+
+**Narrator (Narrative Passages):**
+```ink
+Narrator: The room falls silent.
+Narrator: Outside, rain begins to fall.
+```
+
+**Shorthand for Main NPC:**
+```ink
+npc: This refers to whoever you're talking to.
+```
+
+## Mixing with Tags
+
+Action tags still work normally:
+```ink
+test_npc_back: I'll unlock the door for you.
+# unlock_door:ceo
+test_npc_back: There you go!
+```
+
+## Backward Compatibility
+
+Old tag-based format still works:
+```ink
+=== old_style ===
+# speaker:player
+This still works fine.
+# speaker:npc:test_npc_back
+So does this.
+```
+
+## Best Practices
+
+1. ✅ **Use prefixes for speaker identification**
+2. ✅ **Use tags for game actions** (unlock_door, give_item, etc.)
+3. ✅ **Use "Narrator:" for scene descriptions**
+4. ✅ **Use "Player:" for player dialogue** (case-insensitive)
+5. ✅ **Use "npc:" shorthand for simple conversations**
+6. ✅ **Use specific IDs for multi-NPC conversations**
+```
+
+**✅ TODO:**
+- [ ] Create speaker prefix guide
+- [ ] Update main Ink documentation
+- [ ] Add examples to NPC_INTEGRATION_GUIDE.md
+- [ ] Update copilot-instructions.md
+
+---
+
+### 6.2 Update Code Comments
+
+**Files to Update:**
+- [ ] Add comprehensive JSDoc to `parseDialogueLine()`
+- [ ] Add comprehensive JSDoc to `buildDialogueBlocks()`
+- [ ] Update `determineSpeaker()` JSDoc
+- [ ] Update `showDialogue()` JSDoc
+- [ ] Add inline comments explaining prefix vs tag priority
+
+---

+
+---
+
+## Rollback Plan
+

+4. **Zero Content Impact:** All existing Ink files work unchanged
+
+---
+
+## Success Metrics
+
+After implementation:
+
+- ✅ 0 regressions in existing conversations
+- ✅ test.ink multi-NPC scenario works perfectly
+- ✅ Narrator passages display correctly
+- ✅ Performance remains < 1ms per line parse
+- ✅ Ink writers report improved ease of use
+- ✅ Code coverage > 90% for new methods
+
+---
+
+## Timeline Estimate
+
+- **Phase 1-2 (Core):** 2-3 hours
+- **Phase 3 (Multi-line):** 2-3 hours  
+- **Phase 4 (Narrator):** 1-2 hours
+- **Phase 5 (Testing):** 2-3 hours
+- **Phase 6 (NPC Tags):** 2-3 hours
+- **Phase 7 (Docs):** 1-2 hours
+
+**Total:** ~10-16 hours of development time
+

+# Person-Chat Minigame: Line Prefix Speaker Format
+
+## Date
+November 23, 2025
+
+## Overview
+This document describes the planned improvements to the person-chat minigame to support cleaner per-line speaker specification using a line prefix format.
+
+---
+
+## Current Approach
+
+### Tag-Based Speaker Detection
+The current system uses Ink tags to specify who is speaking:
+
+**Example from test.ink:**
+```ink
+=== colleague_introduction ===
+# speaker:npc:test_npc_front
+Nice to meet you! I'm the lead technician here. FRONT.
+-> player_question
+
+=== player_question ===
+# speaker:player
+What kind of work do you both do here?
+-> front_npc_explains
+```
+
+### How It Currently Works
+1. **Tags Applied Per Knot**: Speaker tags are placed at the start of each Ink knot/stitch
+2. **Block-Level Concern**: Tags apply to all text until the next tag is encountered
+3. **Mixed with Action Tags**: Speaker tags (`# speaker:player`) coexist with game action tags (`# unlock_door:ceo`, `# give_item:keycard`)
+4. **Speaker Detection**: `determineSpeaker()` method in `person-chat-minigame.js` parses tags in reverse order to find the most recent speaker tag
+
+**Supported Tag Formats:**
+- `# speaker:player` → Player character
+- `# speaker:npc` → Main NPC (defaults to conversation NPC)
+- `# speaker:npc:test_npc_back` → Specific NPC by ID
+- `# player` → Shorthand for player (fallback)
+- `# npc` → Shorthand for main NPC (fallback)
+
+### Current Limitations
+
+1. **Writer Burden**: Ink authors must remember to add tags for every speaker change
+2. **Verbose Multi-Speaker Scenes**: Each speaker change requires a new knot/stitch with a tag
+3. **Mixed Concerns**: Speaker identification mixed with game actions in tag system
+4. **Not Line-Granular**: Cannot easily have multiple speakers within a single knot without workarounds
+5. **No Native Narrator Support**: No dedicated way to specify narrative-only passages (no character portrait)
+6. **No Background Control**: Cannot change scene backgrounds mid-conversation
+
+---
+
+## Proposed Approach: Line Prefix Format (Option 1)
+
+### Core Concept
+Parse each dialogue line for an optional `SPEAKER_ID: Text` prefix at the start of the line.
+
+### Syntax Examples
+
+**Multi-NPC Conversation:**
+```ink
+=== group_meeting ===
+test_npc_back: Agent, meet my colleague from the back office.
+test_npc_front: Nice to meet you! I'm the lead technician here.
+Player: What kind of work do you both do here?
+test_npc_back: Well, I handle the front desk operations...
+test_npc_front: I manage all the backend systems.
+```
+
+**Narrative Passages:**
+```ink
+=== tense_moment ===
+test_npc_back: I have something important to tell you.
+Narrator: An awkward silence fills the room.
+Player: What is it?
+```
+
+**Shorthand for Main NPC:**
+```ink
+=== simple_chat ===
+npc: Hey there! How can I help?
+Player: I need some information.
+npc: Sure, what do you need to know?
+```
+
+**Narrator with Character in View:**
+```ink
+=== character_focus ===
+Narrator[test_npc_back]: The technician looks nervous as footsteps approach.
+Narrator[Player]: You feel a knot forming in your stomach.
+Narrator[]: The hallway falls silent.
+```
+
+**Background Changes (Future Enhancement):**
+```ink
+=== scene_transition ===
+test_npc_back: Let me show you something.
+Background=office_night.png: The lights dim as evening falls.
+test_npc_back: See? Everything changes at night.
+```
+
+### Parsing Logic
+
+1. **Line-by-Line Processing**: Each line of text is checked for the prefix pattern
+2. **Regex Patterns**: 
+   - Basic: `/^([A-Za-z_][A-Za-z0-9_]*|Narrator):\s+(.+)$/`
+   - Narrator with character: `/^Narrator\[([A-Za-z_][A-Za-z0-9_]*|)\]:\s+(.+)$/`
+   - Capture Group 1: Speaker ID (letters, numbers, underscores)
+   - Special cases: "Narrator", "Narrator[character_id]", "Narrator[]"
+   - Capture Group 2: Remaining dialogue text
+3. **Speaker Lookup**:
+   - If prefix matches NPC ID → Use that NPC's portrait/name
+   - If prefix is "Player" (case-insensitive) → Use player character
+   - If prefix is "npc" → Use main conversation NPC
+   - If prefix is "Narrator" → Special narrative styling (no portrait, centered text)
+   - If prefix is "Narrator[character_id]" → Narrative text with specified character's portrait
+   - If prefix is "Narrator[]" → Narrative text with no portrait
+   - If no prefix found → **Default to main NPC** (conversation initiator)
+4. **Tag-Based Fallback**: If no prefix detected and within tag context, fall back to existing tag-based speaker detection
+
+### Key Advantages
+
+1. **✅ Natural Readability**: Ink source looks like natural dialogue/screenplay format
+2. **✅ Per-Line Granularity**: Change speaker on every single line without new knots
+3. **✅ Backward Compatible**: Existing tag-based conversations continue to work
+4. **✅ Separation of Concerns**: Speaker identity in text, game actions in tags
+5. **✅ Narrator Support**: Built-in way to write narrative passages
+6. **✅ Easy to Write**: Intuitive for content creators
+7. **✅ Multi-Speaker Friendly**: Perfect for group conversations (see test.ink)
+
+### Integration with Existing Systems
+
+**Tags Remain for Actions:**
+```ink
+=== unlocking_door ===
+helper_npc: I can help you with that door.
+# unlock_door:ceo
+helper_npc: There you go! It's open now.
+Player: Thanks!
+```
+
+**Choice Display Still Works:**
+```ink
+=== decision_point ===
+test_npc_back: What would you like to do?
++ [Ask about the mission] -> ask_mission
++ [Leave] -> leave
+```
+
+**State Variables Still Function:**
+```ink
+VAR has_keycard = false
+
+=== check_keycard ===
+{has_keycard:
+  Player: I have the keycard now.
+  npc: Great! You can access the secure area.
+- else:
+  Player: I need to find a keycard.
+  npc: Check the security office.
+}
+```
+
+---
+
+## NPC Behavior Tag Enhancements
+
+### Current Limitation
+NPC behavior tags (like `# hostile:npc_id`) currently **require** an NPC ID parameter:
+```ink
+test_npc_back: You shouldn't have done that.
+# hostile:test_npc_back
+```
+
+### Proposed Improvements
+
+#### 1. Default to Main NPC
+If no NPC ID is provided, apply to the conversation's main NPC:
+```ink
+test_npc_back: You shouldn't have done that.
+# hostile
+// Automatically makes test_npc_back hostile (main conversation NPC)
+```
+
+#### 2. Multiple NPC IDs (Comma-Separated List)
+Apply behavior to multiple NPCs at once:
+```ink
+# hostile:guard_1,guard_2,guard_3
+// All three guards become hostile simultaneously
+```
+
+#### 3. NPC ID Wildcards/Patterns
+Apply behavior to NPCs matching a pattern:
+```ink
+# hostile:guard_*
+// All NPCs with IDs starting with "guard_" become hostile
+
+# hostile:all
+// All NPCs in the current room become hostile
+
+# friendly:receptionist_*,manager_*
+// All receptionists and managers become friendly
+```
+
+### Affected Tags
+These tags will support the new formats:
+- `hostile` - Make NPC(s) aggressive
+- `friendly` - Make NPC(s) non-aggressive  
+- `influence` - Modify relationship with NPC(s)
+- `suspicious` - Make NPC(s) wary of player
+- Any future behavior-modifying tags
+
+### Implementation Location
+Update `processGameActionTags()` in `js/minigames/helpers/chat-helpers.js` around line 220-240.
+
+---
+
+## Implementation Strategy
+
+### Phase 1: Core Parsing
+- Add `parseDialogueLine(text)` utility function
+- Extract speaker and cleaned text from line prefix
+- Integrate into `determineSpeaker()` method (check prefix first, then fall back to tags)
+
+### Phase 2: Multi-Line Dialogue Handling
+- Enhance `displayAccumulatedDialogue()` to detect speaker changes mid-block
+- Split dialogue blocks by speaker when prefix changes
+- Update `displayDialogueBlocksSequentially()` to handle prefix-based blocks
+
+### Phase 3: Narrator Support
+- Detect "Narrator" prefix
+- Apply special styling (no portrait, centered/italic text)
+- Update CSS for narrator-specific presentation
+
+### Phase 4: Background Changes (Future)
+- Parse `Background=path: text` format
+- Trigger background image swap in UI
+- Add fade/transition effects
+
+### Phase 5: Testing & Documentation
+- Test with existing tag-based conversations (backward compatibility)
+- Test with new prefix-based conversations
+- Test mixed format (tags + prefixes)
+- Update documentation for Ink writers
+
+---
+
+## Migration Path
+
+### Existing Conversations
+**No changes required.** All existing Ink files using tag-based speaker detection will continue to work exactly as before.
+
+### New Conversations
+Writers can choose:
+1. **Pure prefix format** (recommended for new content)
+2. **Pure tag format** (for consistency with old content)
+3. **Mixed format** (prefixes for speakers, tags for actions)
+
+### Example Migration
+
+**Before (Tags):**
+```ink
+=== conversation ===
+# speaker:npc:test_npc_back
+Welcome to the office.
+-> next_part
+
+=== next_part ===
+# speaker:player
+Thanks for having me.
+-> response
+
+=== response ===
+# speaker:npc:test_npc_back
+Let me show you around.
+-> END
+```
+
+**After (Prefixes):**
+```ink
+=== conversation ===
+test_npc_back: Welcome to the office.
+Player: Thanks for having me.
+test_npc_back: Let me show you around.
+-> END
+```
+
+---
+
+## Technical Considerations
+
+### Performance
+- **Minimal overhead**: Single regex check per line
+- **Cached speakers**: Current speaker tracked to avoid re-lookup
+- **Lazy parsing**: Only parse when dialogue text present
+
+### Edge Cases
+1. **Colons in dialogue**: `Player: What time is it: 5pm or 6pm?`
+   - Solution: Prefix pattern only matches at line start + requires valid ID format
+2. **Multiline dialogue blocks**: Lines without prefix inherit current speaker
+3. **Empty lines**: Ignored/stripped before prefix parsing
+4. **Invalid speaker IDs**: Fall back to current speaker or main NPC
+5. **Case sensitivity**: "Player", "player", "PLAYER" all normalized to 'player'
+
+### Compatibility
+- **Ink Compiler**: No changes needed (prefixes are just text)
+- **inkjs Runtime**: No changes needed
+- **Existing Stories**: 100% backward compatible
+- **Rails Backend**: No changes needed (serves pre-compiled JSON)
+
+---
+
+## Success Criteria
+
+1. ✅ Existing tag-based conversations work without modification
+2. ✅ New prefix-based conversations parse correctly
+3. ✅ Speaker changes mid-dialogue block work smoothly
+4. ✅ Narrator passages display without portraits
+5. ✅ Multi-NPC conversations (like test.ink) display correctly
+6. ✅ Performance remains acceptable (no noticeable lag)
+7. ✅ Ink writers find the new format intuitive
+
+---
+
+## Future Enhancements
+
+### Emotion Variants
+```ink
+test_npc_back[angry]: I can't believe you did that!
+test_npc_back[happy]: But I'm glad it worked out.
+```
+
+### Location Hints
+```ink
+test_npc_back@lab: Let me show you the equipment here.
+```
+
+### Sound Effects
+```ink
+Sound=door_slam.mp3: The door slams shut.
+test_npc_back: What was that?!
+```

+```
+
+### Examples
+
+**Player:**
+```ink
+Player: I need to investigate this room.
+```
+
+**Specific NPC:**
+```ink
+test_npc_back: Let me help you with that.
+```
+
+**Main NPC Shorthand:**
+```ink
+npc: This refers to whoever you're talking to.
+```
+
+**No Prefix (Defaults to Main NPC):**
+```ink
+=== greeting ===
+Hello there! // Main conversation NPC
+Player: Hi!
+What brings you here? // Also main NPC
+```
+
+---
+
+## Narrator Syntax
+
+### Basic Narrator (No Portrait)
+```ink
+Narrator: The room falls silent.
+Narrator: Outside, rain begins to fall.
+```
+
+### Narrator with Character in View
+Show narrative text while keeping a specific character's portrait visible:
+
+```ink
+Narrator[test_npc_back]: The technician shifts nervously.
+Narrator[Player]: You feel a sense of dread.
+Narrator[security_guard]: The guard's hand moves toward his weapon.
+```
+
+### Narrator with Explicit No Portrait
+```ink
+Narrator[]: The hallway is completely empty.
+```
+
+**When to use each:**
+- `Narrator:` - Default, no portrait (scene descriptions)
+- `Narrator[character]:` - Focus on specific character during narration
+- `Narrator[]` - Explicitly empty scene (same as default, more clear)
+
+---
+
+## NPC Behavior Tags
+
+### Basic Syntax
+```ink
+# BEHAVIOR_TAG:TARGET_SPEC
+```
+
+### Target Specifications
+
+#### 1. No Target (Main NPC)
+```ink
+test_npc_back: You betrayed me!
+# hostile
+// Makes test_npc_back hostile
+```
+
+#### 2. Single NPC
+```ink
+# hostile:security_guard
+// Makes security_guard hostile
+```
+
+#### 3. Multiple NPCs (Comma-Separated)
+```ink
+# hostile:guard_1,guard_2,guard_3
+// All three guards become hostile
+```
+
+#### 4. Wildcard Pattern
+```ink
+# hostile:guard_*
+// All NPCs with IDs starting with "guard_"
+
+# hostile:scientist_*,engineer_*
+// Multiple patterns supported
+```
+
+#### 5. All NPCs in Room
+```ink
+# hostile:all
+// Every NPC in the current room
+```
+
+### Behavior Tags
+
+**`hostile`** - Make NPC(s) aggressive/hostile
+```ink
+# hostile
+# hostile:npc_id
+# hostile:npc1,npc2
+# hostile:pattern_*
+# hostile:all
+```
+
+**`friendly`** - Make NPC(s) non-aggressive/friendly
+```ink
+# friendly
+# friendly:npc_id
+# friendly:guard_*
+```
+
+**`influence`** - Modify relationship score
+```ink
+# influence:npc_id:+10
+# influence:npc_id:-20
+# influence:receptionist_*:+15
+```
+
+---
+
+## Complete Examples
+
+### Multi-Character Conversation with Narrator
+```ink
+=== tense_standoff ===
+test_npc_back: We need to talk about what you did.
+Narrator[test_npc_back]: His hand trembles slightly.
+Player: I can explain.
+Narrator[Player]: You feel the weight of their stares.
+test_npc_front: Make it quick.
+Narrator: The room holds its breath.
+```
+
+### Group Behavior Change
+```ink
+=== alarm_triggered ===
+security_guard: INTRUDER ALERT!
+Narrator: Klaxons blare throughout the facility.
+# hostile:guard_*
+Narrator[Player]: Every guard in the building is now hunting you.
+Player: Time to run!
+```
+
+### Conditional Behavior
+```ink
+VAR insulted_scientists = false
+
+=== lab_entrance ===
+{insulted_scientists:
+    lead_scientist: You're not welcome here anymore.
+    # hostile:scientist_*
+    Narrator: The entire research team glares at you.
+- else:
+    lead_scientist: Welcome to the lab!
+    # friendly:scientist_*
+    Narrator: The scientists smile warmly.
+}
+```
+
+### Mixed Format (Backward Compatible)
+```ink
+=== old_and_new ===
+# speaker:npc:test_npc_back
+This line uses old tag-based format.
+test_npc_back: This line uses new prefix format.
+# unlock_door:ceo
+test_npc_back: The door is now unlocked!
+# hostile:security_*
+Narrator[test_npc_back]: He realizes the alarm will trigger soon.
+Player: We need to hurry!
+```
+
+---
+
+## Best Practices
+
+### ✅ DO
+
+**Use prefixes for speaker clarity:**
+```ink
+test_npc_back: I'm the back office technician.
+test_npc_front: And I'm the front desk technician.
+Player: Nice to meet you both!
+```
+
+**Use narrator for scene descriptions:**
+```ink
+Narrator: Thunder rumbles in the distance.
+Narrator: The lights flicker ominously.
+```
+
+**Use narrator with character for dramatic focus:**
+```ink
+Narrator[villain]: A cruel smile crosses their face.
+```
+
+**Use default speaker for simple conversations:**
+```ink
+=== simple_chat ===
+Hey there, need some help? // Main NPC
+Player: Yes, please!
+What do you need? // Main NPC
+```
+
+**Use behavior tag enhancements for groups:**
+```ink
+# hostile:all // Simple and clear
+# hostile:guard_1,guard_2,guard_3 // Explicit control
+# hostile:guard_* // Pattern for flexibility
+```
+
+### ❌ DON'T
+
+**Don't mix speaker prefix with speaker tag:**
+```ink
+# speaker:player
+Player: This is redundant and confusing
+```
+
+**Don't use narrator for dialogue:**
+```ink
+// Wrong:
+Narrator: "Hello," says the guard.
+
+// Correct:
+security_guard: Hello.
+```
+
+**Don't forget the space after colon:**
+```ink
+// Wrong:
+Player:Hello!
+
+// Correct:
+Player: Hello!
+```
+
+---
+
+## Debugging Tips
+
+### Check Console Logs
+
+**Speaker detection:**
+```
+🎯 Speaker detected from prefix: test_npc_back
+```
+
+**Narrator mode:**
+```
+📖 Narrator with character: test_npc_back
+```
+
+**NPC targeting:**
+```
+🎯 NPC target: pattern "guard_*"
+🔍 Pattern "guard_*" matched: [guard_1, guard_2, guard_3]
+```
+
+**Block building:**
+```
+📦 Built 3 dialogue block(s) from 8 line(s)
+📋 Displaying line 1/2 from block 2/3: test_npc_front
+```
+
+### Common Issues
+
+**Portrait not showing during narrator:**
+- Check character ID spelling: `Narrator[test_npc_back]:`
+- Verify NPC exists in current room
+- Check console for "Narrator character not found" warning
+
+**Behavior tag not working:**
+- Verify NPC ID is correct
+- Check if NPC is in current room (for pattern matching)
+- Look for "No NPCs found" warning in console
+
+**Speaker not changing:**
+- Verify prefix format: `SPEAKER: ` (note space after colon)
+- Check for typos in speaker ID
+- Ensure speaker ID matches NPC ID or "Player"
+
+---
+
+## Migration from Old Format
+
+### Before (Tag-Based)
+```ink
+=== conversation ===
+# speaker:npc:test_npc_back
+Welcome!
+# speaker:player
+Hello!
+# speaker:npc:test_npc_back
+How can I help?
+```
+
+### After (Prefix-Based)
+```ink
+=== conversation ===
+test_npc_back: Welcome!
+Player: Hello!
+test_npc_back: How can I help?
+```
+
+**Both formats work!** Choose what's clearest for your content.
+
+---
+
+## Version Compatibility
+
+✅ **Backward Compatible** - All existing Ink files work unchanged
+✅ **Forward Compatible** - New features work with existing system
+✅ **Mix and Match** - Can use old and new syntax together

+# Implementation Plan Review #1
+## Date: November 23, 2025
+## Reviewer: AI Assistant
+
+---
+
+## Executive Summary
+
+This review analyzes the proposed line prefix speaker format and NPC behavior tag enhancements against the existing Break Escape codebase. The plans are **generally sound** but several critical integration points, edge cases, and implementation details require attention before development begins.
+
+**Overall Assessment:** ✅ **APPROVED WITH MODIFICATIONS**
+
+**Risk Level:** 🟡 **MEDIUM** - Backward compatibility is well-considered, but complex dialogue flow logic needs careful attention.
+
+---
+
+## 1. Architecture & Integration Analysis
+
+### 1.1 Current System Architecture
+
+**Discovered Structure:**
+```
+PersonChatMinigame (Controller)
+├── PersonChatUI (View/Rendering)
+│   ├── PersonChatPortraits (Portrait Renderer)
+│   └── DOM manipulation
+├── PhoneChatConversation (Reused from phone-chat)
+│   └── InkEngine (Ink story runtime)
+└── chat-helpers.js (Shared utilities)
+    └── processGameActionTags()
+    └── determineSpeaker() [UNUSED - local version exists]
+```
+
+**Key Finding:** The implementation plan references `determineSpeaker()` from `chat-helpers.js`, but the actual codebase uses a **LOCAL** version in `PersonChatMinigame` class (lines 500-543). This is a critical discrepancy.
+
+### 1.2 Current Speaker Detection Logic
+
+**Actual Implementation (person-chat-minigame.js:500-543):**
+```javascript
+determineSpeaker(result) {
+    if (!result.tags || result.tags.length === 0) {
+        return this.npc.id; // ✅ Already defaults to main NPC!
+    }
+    
+    // Checks tags in reverse order
+    // Supports: speaker:player, speaker:npc, speaker:npc:character_id
+    // Falls back to: player, npc (simple tags)
+    
+    return this.npc.id; // Default
+}
+```
+
+**✅ GOOD NEWS:** The codebase **already defaults to main NPC** when no tags are present. This means our "default to main NPC" feature is partially implemented!
+
+**⚠️ ISSUE:** The implementation plan doesn't acknowledge this existing behavior.
+
+---
+
+## 2. Detailed Code Review by Phase
+
+### Phase 1: Core Parsing Function
+
+#### 2.1.1 parseDialogueLine() Implementation
+
+**Plan Location:** IMPLEMENTATION_PLAN.md, Phase 1.1
+
+**Assessment:** ✅ **SOUND DESIGN** with minor concerns
+
+**Issues Identified:**
+
+1. **Regex Case Sensitivity:**
+   ```javascript
+   // Plan uses: /^([A-Za-z_][A-Za-z0-9_]*|Narrator):\s+(.+)$/
+   // Better: /^([A-Za-z_][A-Za-z0-9_]*|Narrator):\s+(.+)$/i
+   ```
+   **Recommendation:** Add `i` flag for case-insensitive matching to support "narrator:", "NARRATOR:", "Narrator:"
+
+2. **Empty Text After Colon:**
+   ```javascript
+   // Plan regex requires: .+ (one or more characters)
+   // What about: "Player: " (whitespace only)?
+   ```
+   **Recommendation:** Add validation for empty dialogue after prefix stripping
+
+3. **Colon in Dialogue Text:**
+   The regex correctly captures only the FIRST colon as delimiter. ✅ Good.
+   Example: `"Player: The code is: 1234"` → speaker="Player", text="The code is: 1234"
+
+4. **Multiple Spaces After Colon:**
+   ```javascript
+   // Plan regex: :\s+ (one or more whitespace)
+   // Example: "Player:    Hello" → works correctly
+   ```
+   ✅ Handled correctly
+
+**Code Quality Concerns:**
+
+```javascript
+// Plan returns:
+return { speaker: null, text: line || '', hasPrefix: false, isNarrator: false, narratorCharacter: null };
+
+// Issue: Five return properties - consider using a class or consistent factory
+```
+
+**Recommendation:** Create a `ParsedDialogueLine` class or factory function for consistency:
+```javascript
+function createParsedLine(speaker, text, hasPrefix, isNarrator, narratorCharacter) {
+    return { speaker, text, hasPrefix, isNarrator, narratorCharacter };
+}
+```
+
+#### 2.1.2 normalizeSpeakerId() Implementation
+
+**Assessment:** ✅ **GOOD** with one edge case
+
+**Issue - Character ID Validation:**
+```javascript
+// Plan code:
+if (this.characters[speakerId]) {
+    return speakerId;
+}
+
+// What if speakerId is "player" but this.characters["player"] doesn't exist?
+// This could happen if character index building fails
+```
+
+**Recommendation:** Add defensive fallback:
+```javascript
+if (lower === 'player') {
+    return 'player'; // Always return 'player' for player character
+}
+
+// Later, in character lookup, handle missing characters gracefully
+```
+
+---
+
+### Phase 2: Speaker Determination Integration
+
+#### 2.2.1 determineSpeaker() Modifications
+
+**Plan Location:** IMPLEMENTATION_PLAN.md, Phase 2.1
+
+**CRITICAL FINDING:** Implementation plan shows:
+```javascript
+determineSpeaker(result, textLine = null) {
+    // Priority 1: Check for line prefix format
+    if (textLine || result.text) {
+        const lineToCheck = textLine || result.text.split('\n')[0];
+        const parsed = this.parseDialogueLine(lineToCheck);
+        // ...
+    }
+    
+    // Priority 2: Fall back to tag-based detection (existing logic)
+    // ...
+}
+```
+
+**⚠️ ISSUE:** This changes the function signature from `determineSpeaker(result)` to `determineSpeaker(result, textLine)`.
+
+**Impact Analysis:**
+```bash
+# Searching for determineSpeaker() calls...
+# Found: 0 direct calls to determineSpeaker() in person-chat-minigame.js
+# It's only used internally in createDialogueBlocks()
+```
+
+**Actual Usage (line 699):**
+```javascript
+let speaker = this.npc.id;
+if (tag.includes('speaker:player')) {
+    speaker = 'player';
+} else if (tag.includes('speaker:npc:')) {
+    // ...
+}
+// determineSpeaker() is NOT called here!
+```
+
+**⚠️ MAJOR DISCREPANCY:** The `determineSpeaker()` method exists but is **NOT actually used** in the dialogue display flow! Instead, speaker detection is hardcoded in `createDialogueBlocks()`.
+
+**Recommendation:** 
+1. Refactor `createDialogueBlocks()` to use `determineSpeaker()`
+2. Then enhance `determineSpeaker()` with prefix support
+3. This ensures consistency and maintainability
+
+---
+
+### Phase 3: Multi-Line Dialogue Handling
+
+#### 2.3.1 buildDialogueBlocks() vs. createDialogueBlocks()
+
+**CRITICAL NAMING CONFLICT:**
+
+**Plan uses:** `buildDialogueBlocks(lines, result)`  
+**Codebase has:** `createDialogueBlocks(lines, tags)` (line 677)
+
+**⚠️ ISSUE:** Different function names will cause confusion. Both functions serve the same purpose.
+
+**Recommendation:** Either:
+- A) Rename plan function to match existing `createDialogueBlocks()`
+- B) Deprecate existing and use new name
+- **Preferred:** Option A - match existing naming
+
+#### 2.3.2 Current Block Creation Logic
+
+**Existing Implementation (lines 677-744):**
+```javascript
+createDialogueBlocks(lines, tags) {
+    // Special case: NO tags at all - defaults to main NPC ✅
+    if (!tags || tags.length === 0) {
+        // All lines belong to main NPC
+    }
+    
+    // Groups lines by speaker based on tags
+    // Uses tag index to determine line boundaries
+}
+```
+
+**Plan Implementation:**
+```javascript
+buildDialogueBlocks(lines, result) {
+    for (const line of lines) {
+        const parsed = this.parseDialogueLine(line);
+        // Determine speaker per line (not per tag)
+    }
+}
+```
+
+**⚠️ ARCHITECTURAL DIFFERENCE:**
+
+| Current | Planned |
+|---------|---------|
+| Tag-driven (tags → lines) | Line-driven (lines → speakers) |
+| One tag can cover multiple lines | Each line checked independently |
+| Tag index = line grouping | Line-by-line parsing |
+
+**Impact:** The planned approach is MORE granular but SLOWER (O(n) line parsing vs O(t) tag parsing where n >> t).
+
+**Recommendation:** 
+1. Keep line-by-line approach for flexibility
+2. Add performance optimization: cache parsed results
+3. Consider lazy parsing (only parse when no prefix found in previous line)
+
+#### 2.3.3 Speaker Continuity Logic
+
+**Plan Code:**
+```javascript
+} else if (currentBlock) {
+    // No prefix - continue with current speaker
+    lineSpeaker = currentBlock.speaker;
+} else {
+    // First line, no prefix - default to main NPC
+    lineSpeaker = this.npc.id;
+}
+```
+
+**✅ EXCELLENT:** This handles speaker continuity correctly. Lines without prefixes inherit the previous speaker.
+
+**Edge Case - Empty Current Block:**
+What if `currentBlock.speaker` is undefined due to malformed data?
+
+**Recommendation:** Add null check:
+```javascript
+lineSpeaker = currentBlock?.speaker || this.npc.id;
+```
+
+---
+
+### Phase 4: Narrator Support
+
+#### 2.4.1 Narrator with Character Feature
+
+**Plan introduces:** `Narrator[character_id]: Text`
+
+**Assessment:** ✅ **INNOVATIVE** but has integration challenges
+
+**CSS Integration Issue:**
+
+**Plan shows (IMPLEMENTATION_PLAN.md):**
+```css
+.person-chat-dialogue-box.narrator-mode {
+    background-color: rgba(20, 20, 20, 0.85);
+    border-color: #666;
+}
+```
+
+**Existing CSS (person-chat-minigame.css):**
+```css
+/* Current styling uses different class structure */
+.person-chat-caption-area { }
+.person-chat-dialogue-box { }
+.person-chat-speaker-name { }
+```
+
+**⚠️ ISSUE:** Plan assumes a `.narrator-mode` class, but existing CSS structure may not support this cleanly.
+
+**Recommendation:** Review actual CSS file structure and ensure narrator styling integrates without breaking existing layouts.
+
+#### 2.4.2 showDialogue() Signature Change
+
+**Current Signature (person-chat-ui.js:216):**
+```javascript
+showDialogue(text, characterId = 'npc', preserveChoices = false)
+```
+
+**Planned Signature:**
+```javascript
+showDialogue(text, speaker, preserveChoices = false, isNarrator = false, narratorCharacter = null)
+```
+
+**⚠️ BREAKING CHANGE:** Adding two new parameters
+
+**Impact Analysis:**
+- 20 calls to `showDialogue()` found in codebase
+- All use 1-3 parameters (text, speaker, preserveChoices)
+- New parameters are optional with defaults ✅
+- **Backward compatible** ✅
+
+**Edge Case - narratorCharacter Validation:**
+
+**Plan code:**
+```javascript
+if (narratorCharacter) {
+    const characterData = this.getCharacterData(narratorCharacter);
+    if (characterData) {
+        this.portraitRenderer.showPortrait(characterData);
+    } else {
+        this.portraitRenderer.hidePortrait();
+        console.warn(`⚠️ Narrator character not found: ${narratorCharacter}`);
+    }
+}
+```
+
+**✅ GOOD:** Graceful fallback when character not found
+
+**Additional Check Needed:**
+What if `narratorCharacter` is `"player"` but player data is missing?
+
+**Recommendation:** Add explicit player character fallback:
+```javascript
+if (narratorCharacter === 'player') {
+    const playerData = this.playerData || this.characters['player'];
+    if (playerData) {
+        this.portraitRenderer.showPortrait(playerData);
+    }
+}
+```
+
+---
+
+### Phase 5: Testing Strategy
+
+#### 2.5.1 Test Ink File Structure
+
+**Plan File:** `scenarios/ink/test-line-prefix.ink`
+
+**Assessment:** ✅ **COMPREHENSIVE** test coverage
+
+**Issues Identified:**
+
+1. **Missing Test Case - Malformed Prefix:**
+   ```ink
+   test_npc_back : Missing space before colon
+   test_npc_back:Missing space after colon
+   test_npc_back :  : Double colon
+   ```
+   **Recommendation:** Add malformed input tests
+
+2. **Missing Test Case - Very Long Lines:**
+   ```ink
+   Player: [Insert 1000+ character line here]
+   ```
+   **Recommendation:** Test performance with long dialogue
+
+3. **Missing Test Case - Unicode Characters:**
+   ```ink
+   test_npc_back: こんにちは！ 你好！ مرحبا!
+   Narrator[test_npc]: 🎭 Emoji test 🎪
+   ```
+   **Recommendation:** Add internationalization test
+
+4. **Narrator[]: Explicit Empty Test Missing**
+   The plan shows `Narrator[]:` but doesn't test it in the ink file
+   **Recommendation:** Add to test file
+
+---
+
+### Phase 6: NPC Behavior Tag Enhancements
+
+#### 2.6.1 parseNPCTargets() Implementation
+
+**Plan Location:** IMPLEMENTATION_PLAN.md, Phase 6.1
+
+**Assessment:** ✅ **WELL DESIGNED** with implementation concerns
+
+**Issue 1 - Function Location:**
+
+**Plan says:** "Add to `chat-helpers.js`"
+
+**Problem:** This is a module function, not a class method. How will it access `window.npcManager`, `window.rooms`, etc.?
+
+**Current Pattern in chat-helpers.js:**
+```javascript
+export function processGameActionTags(tags, ui) {
+    if (!window.NPCGameBridge) { // Accesses global ✅
+        // ...
+    }
+}
+```
+
+**✅ OKAY:** Using global `window` object is the established pattern
+
+**Issue 2 - Room Context:**
+
+**Plan code:**
+```javascript
+function parseNPCTargets(param, mainNpcId, currentRoomId) {
+    // Uses currentRoomId parameter
+}
+```
+
+**Problem:** How is `currentRoomId` obtained?
+
+**Solution Needed:**
+```javascript
+// Option 1: Pass from caller
+processGameActionTags(tags, ui, currentRoomId);
+
+// Option 2: Access global
+const currentRoomId = window.currentRoom || window.player?.currentRoom;
+```
+
+**Recommendation:** Use Option 2 (global access) for consistency with existing patterns
+
+#### 2.6.2 Pattern Matching Implementation
+
+**Plan code:**
+```javascript
+function getNPCsByPattern(pattern, roomId = null) {
+    const regexPattern = '^' + pattern.replace(/\*/g, '.*') + '$';
+    const regex = new RegExp(regexPattern, 'i');
+    // ...
+}
+```
+
+**⚠️ SECURITY CONCERN:** User-provided pattern converted to regex without sanitization
+
+**Attack Vector:**
+```ink
+# hostile:.*)(|(.* 
+// Creates invalid regex, causes crash
+```
+
+**Recommendation:** Add regex validation and error handling:
+```javascript
+function getNPCsByPattern(pattern, roomId = null) {
+    try {
+        // Escape special regex characters except *
+        const sanitized = pattern.replace(/[.+?^${}()|[\]\\]/g, '\\$&');
+        const regexPattern = '^' + sanitized.replace(/\*/g, '.*') + '$';
+        const regex = new RegExp(regexPattern, 'i');
+        // ...
+    } catch (error) {
+        console.error(`Invalid NPC pattern: ${pattern}`, error);
+        return [];
+    }
+}
+```
+
+#### 2.6.3 "all" Keyword Implementation
+
+**Plan code:**
+```javascript
+if (trimmed.toLowerCase() === 'all') {
+    console.log(`🎯 NPC target: ALL in room ${currentRoomId}`);
+    return getAllNPCsInRoom(currentRoomId);
+}
+```
+
+**Edge Case - No Current Room:**
+What if player is between rooms or currentRoomId is undefined?
+
+**Recommendation:** Add fallback:
+```javascript
+if (trimmed.toLowerCase() === 'all') {
+    if (!currentRoomId) {
+        console.warn('⚠️ No current room context for "all" target');
+        return [mainNpcId]; // Fallback to main NPC
+    }
+    return getAllNPCsInRoom(currentRoomId);
+}
+```
+
+#### 2.6.4 Comma-Separated List Parsing
+
+**Plan code:**
+```javascript
+if (trimmed.includes(',')) {
+    const npcIds = trimmed.split(',').map(id => id.trim()).filter(id => id);
+    return npcIds;
+}
+```
+
+**⚠️ ISSUE:** No validation that NPCs exist
+
+**Edge Case:**
+```ink
+# hostile:guard_1,guard_2,nonexistent_npc,guard_3
+// Should this affect only valid NPCs or fail entirely?
+```
+
+**Recommendation:** Add validation with warning:
+```javascript
+const npcIds = trimmed.split(',').map(id => id.trim()).filter(id => id);
+const validIds = npcIds.filter(id => {
+    const exists = npcExists(id);
+    if (!exists) {
+        console.warn(`⚠️ NPC not found: ${id}`);
+    }
+    return exists;
+});
+return validIds;
+```
+
+---
+
+## 3. Performance Analysis
+
+### 3.1 Parsing Overhead
+
+**Concern:** Every line of dialogue is now parsed with regex
+
+**Current Flow:**
+```
+1 tag check → Speaker determined → Display all lines
+O(t) where t = number of tags
+```
+
+**Planned Flow:**
+```
+For each line:
+  → Parse with regex
+  → Normalize speaker ID
+  → Check character exists
+  → Build block
+O(n * r) where n = lines, r = regex operations
+```
+
+**Impact Estimate:**
+- Simple conversation (10 lines): Negligible (~1ms)
+- Complex conversation (100 lines): ~10ms
+- Very long conversation (1000 lines): ~100ms
+
+**Recommendation:** 
+1. ✅ Accept overhead (minimal for typical use)
+2. If needed: Add caching layer for repeated patterns
+3. Profile in real scenarios before optimizing
+
+### 3.2 Character Lookup Performance
+
+**Plan uses:** `this.characters[characterId]`
+
+**Current Structure:**
+```javascript
+this.characters = {
+    'player': { ... },
+    'test_npc_back': { ... },
+    'test_npc_front': { ... }
+}
+```
+
+**✅ O(1) lookup:** No performance concerns
+
+---
+
+## 4. Edge Cases & Error Handling
+
+### 4.1 Malformed Input
+
+| Input | Expected Behavior | Plan Addresses? |
+|-------|------------------|----------------|
+| `"Player:"` (no text) | Ignore or error? | ❌ Not specified |
+| `"Player :Text"` (space before colon) | No match | ✅ Handled |
+| `"Player: "` (only whitespace) | Empty dialogue? | ❌ Not addressed |
+| `"Invalid_123: Text"` (unknown speaker) | Fallback to main NPC? | ⚠️ Partially |
+| Line with 100 colons | Use first colon only | ✅ Regex handles |
+| Emoji in speaker ID: `"🎭: Text"` | No match | ✅ Rejected by regex |
+
+**Recommendation:** Add explicit empty text check:
+```javascript
+if (!dialogueText || !dialogueText.trim()) {
+    console.warn(`⚠️ Empty dialogue after prefix: "${line}"`);
+    return { speaker: null, text: line, hasPrefix: false, isNarrator: false, narratorCharacter: null };
+}
+```
+
+### 4.2 Race Conditions
+
+**Scenario:** Player advances dialogue quickly while speaker is still being processed
+
+**Current Protection:** None identified in plan
+
+**Recommendation:** Add state locking:
+```javascript
+if (this.isProcessingDialogue) {
+    console.log('⏳ Already processing dialogue, ignoring input');
+    return;
+}
+this.isProcessingDialogue = true;
+// ... process dialogue ...
+this.isProcessingDialogue = false;
+```
+
+### 4.3 Memory Leaks
+
+**Concern:** `charactersWithParallax` Set grows indefinitely
+
+**Current Code (person-chat-ui.js:304):**
+```javascript
+this.charactersWithParallax.add(speakerId);
+```
+
+**Issue:** Set is never cleared, even across multiple conversations
+
+**Recommendation:** Add cleanup in conversation end:
+```javascript
+destroy() {
+    this.charactersWithParallax.clear();
+    // ... other cleanup ...
+}
+```
+
+---
+
+## 5. Backward Compatibility Verification
+
+### 5.1 Existing Conversations Audit
+
+**Files to Test:**
+- `scenarios/ink/helper-npc.json` ✅ Mentioned
+- `scenarios/ink/neye-eve.json` ✅ Mentioned
+- `scenarios/ink/gossip-girl.json` ✅ Mentioned
+- `scenarios/ink/test.ink` ✅ Test file
+
+**Verification Needed:**
+1. All existing Ink files use tag-based speaker detection
+2. No existing files accidentally use "SPEAKER_ID:" pattern
+3. No files use "Narrator:" as regular dialogue
+
+**Recommendation:** 
+1. Search all .ink/.json files for pattern: `/^[A-Za-z_][A-Za-z0-9_]*:/`
+2. If matches found, audit them for conflicts
+3. Add migration guide for content creators
+
+### 5.2 API Compatibility Matrix
+
+| Method | Current | Planned | Compatible? |
+|--------|---------|---------|-------------|
+| `showDialogue(text, speaker)` | ✅ | ✅ (3 optional params) | ✅ YES |
+| `determineSpeaker(result)` | ✅ | ✅ (1 optional param) | ✅ YES |
+| `createDialogueBlocks(lines, tags)` | ✅ | Renamed to `buildDialogueBlocks` | ⚠️ BREAKING |
+| `processGameActionTags(tags, ui)` | ✅ | Enhanced with new helpers | ✅ YES |
+
+**Overall:** ✅ **BACKWARD COMPATIBLE** except for internal renaming
+
+---

+
+---
+
+## 7. Critical Issues Summary
+
+### 🔴 CRITICAL (Must Fix Before Implementation)
+
+1. **Function Naming Conflict:** `buildDialogueBlocks()` vs `createDialogueBlocks()` - must resolve
+2. **determineSpeaker() Not Used:** Current code doesn't actually call `determineSpeaker()` - refactoring needed
+3. **Regex Security:** Pattern matching in NPC tags needs input sanitization
+
+### 🟡 HIGH (Should Fix During Implementation)
+
+4. **Empty Dialogue Detection:** No handling for `"Speaker: "` (empty text after prefix)
+5. **Character Validation:** No validation that NPC IDs in comma-separated lists exist
+6. **Room Context Missing:** `parseNPCTargets()` needs current room ID source
+
+### 🟢 MEDIUM (Address If Time Permits)
+
+7. **Performance Optimization:** Line-by-line parsing vs tag-based grouping trade-off
+8. **Memory Leak:** `charactersWithParallax` Set never cleared
+9. **Race Condition:** No locking during dialogue processing
+
+### 🔵 LOW (Post-MVP Enhancements)
+
+10. **Internationalization:** No tests for Unicode characters in dialogue
+11. **Very Long Lines:** No performance testing for 1000+ character dialogue
+12. **Error Recovery:** No mechanism to skip malformed lines and continue
+
+---
+
+## 8. Recommendations
+
+### 8.1 Implementation Order Adjustments
+
+**Suggested Change to Phase Order:**
+
+**Original:** 1 → 2 → 3 → 4 → 5 → 6 → 7
+
+**Recommended:** 
+1. **Phase 0.5:** Refactor existing code to use `determineSpeaker()` consistently
+2. **Phase 1:** Core parsing (as planned)
+3. **Phase 2:** Speaker determination (as planned)
+4. **Phase 2.5:** Fix naming conflicts (`createDialogueBlocks` → `buildDialogueBlocks`)
+5. **Phase 3:** Multi-line dialogue (as planned)
+6. **Phase 4:** Narrator support (as planned)
+7. **Phase 5:** Testing (expanded with edge cases)
+8. **Phase 6:** NPC behavior tags (with security fixes)
+9. **Phase 7:** Documentation (as planned)
+
+### 8.2 Required Code Changes
+
+#### Before Starting Implementation:
+
+```javascript
+// 1. Add to person-chat-minigame.js
+class PersonChatMinigame {
+    constructor() {
+        // ...
+        this.isProcessingDialogue = false; // Add state lock
+    }
+}
+
+// 2. Rename in person-chat-minigame.js (line 677)
+// OLD: createDialogueBlocks(lines, tags)
+// NEW: buildDialogueBlocks(lines, result) 
+
+// 3. Fix speaker detection to actually use determineSpeaker()
+// Instead of inline tag parsing in buildDialogueBlocks
+```
+
+### 8.3 Additional Tests Needed
+
+```ink
+// Add to test-line-prefix.ink
+
+=== edge_cases ===
+Player: Normal dialogue
+Player:NoSpace
+Player :SpaceBeforeColon
+Player:  MultipleSpaces
+: NoSpeaker
+Invalid$Speaker: Should fail gracefully
+Player: Text with: multiple: colons: works: fine
+Narrator[nonexistent_npc]: Should hide portrait
+Narrator[]: Empty brackets test
+-> END
+
+=== stress_test ===
+Player: [1000 character line here...]
+test_npc_back: [Unicode: こんにちは 你好 مرحبا 🎭]
+-> END
+```
+
+### 8.4 Documentation Updates Needed
+
+1. **Add to IMPLEMENTATION_PLAN.md:**
+   ```markdown
+   ## Phase 0: Pre-Implementation Refactoring
+   
+   **Goal:** Consolidate speaker detection logic before adding new features
+   
+   **Tasks:**
+   - Refactor createDialogueBlocks() to use determineSpeaker()
+   - Rename createDialogueBlocks() → buildDialogueBlocks()
+   - Add state locking for dialogue processing
+   ```
+
+2. **Add to OVERVIEW.md:**
+   ```markdown
+   ## Technical Limitations
+   
+   - Speaker IDs must match regex: [A-Za-z_][A-Za-z0-9_]*
+   - Maximum line length: ~10,000 characters (performance degrades)
+   - Narrator character must exist in current room context
+   - Pattern matching in NPC tags is case-insensitive
+   ```
+
+3. **Add to QUICK_REFERENCE.md:**
+   ```markdown
+   ## Troubleshooting
+   
+   **"Speaker not changing despite prefix"**
+   - Check for typos in speaker ID
+   - Verify NPC exists in current room
+   - Look for regex validation errors in console
+   
+   **"Narrator showing wrong character"**
+   - Character ID must match exactly
+   - Use Narrator[] for no portrait
+   - Check character is in same room as conversation
+   ```
+
+---
+
+## 9. Security & Safety Review
+
+### 9.1 Input Validation
+
+**Current Plan:** ⚠️ Minimal input validation
+
+**Risks:**
+- Malicious Ink files could cause crashes with invalid regex patterns
+- Very long speaker IDs could cause UI overflow
+- Special characters in speaker IDs could break CSS selectors
+
+**Recommendations:**
+1. **Maximum Speaker ID Length:** Enforce 50 character limit
+2. **Whitelist Characters:** Only allow `[A-Za-z0-9_]`
+3. **Sanitize for CSS:** Escape speaker IDs used in CSS class names
+4. **Maximum Dialogue Length:** Warn at 5000 characters, truncate at 10000
+
+### 9.2 Resource Exhaustion
+
+**Scenario:** Malicious Ink file with 10,000 dialogue lines
+
+**Current Protection:** None
+
+**Recommendation:**
+```javascript
+const MAX_DIALOGUE_LINES = 1000;
+
+buildDialogueBlocks(lines, result) {
+    if (lines.length > MAX_DIALOGUE_LINES) {
+        console.error(`⚠️ Dialogue exceeds maximum lines: ${lines.length}`);
+        lines = lines.slice(0, MAX_DIALOGUE_LINES);
+        this.ui.showNotification('Dialogue truncated (too long)', 'warning');
+    }
+    // ... continue processing ...
+}
+```
+
+---
+
+## 10. Final Recommendations
+
+### 10.1 Must Do Before Implementation
+
+1. ✅ **Resolve naming conflicts** (`createDialogueBlocks` vs `buildDialogueBlocks`)
+2. ✅ **Refactor to use `determineSpeaker()`** consistently
+3. ✅ **Add input sanitization** to NPC pattern matching
+4. ✅ **Add empty dialogue text validation**
+5. ✅ **Document current implementation state** in plan
+
+### 10.2 Should Do During Implementation
+
+6. ✅ **Add state locking** for dialogue processing
+7. ✅ **Validate NPC IDs** in comma-separated lists
+8. ✅ **Add comprehensive edge case tests**
+9. ✅ **Clear `charactersWithParallax` Set** on conversation end
+10. ✅ **Add "all" keyword safety checks**
+
+### 10.3 Could Do Post-MVP
+
+11. 🔮 **Performance profiling** on large conversations
+12. 🔮 **Internationalization tests**
+13. 🔮 **Visual debugging tool** for dialogue flow
+14. 🔮 **Hot-reload for Ink testing**
+
+---
+
+## 11. Approval Status
+
+### Overall Assessment
+
+**✅ APPROVED WITH CONDITIONS**
+
+The implementation plans are **well-designed and thoughtfully structured**. The backward compatibility strategy is sound, and the feature set addresses real usability pain points. However, several critical integration issues must be resolved before development begins.
+
+### Conditions for Approval
+
+1. **Must address all 🔴 CRITICAL issues** (3 items)
+2. **Must address all 🟡 HIGH issues** (3 items)  
+3. **Must update documentation** to reflect actual codebase state
+4. **Must add comprehensive edge case tests**
+
+### Estimated Additional Time Required
+
+- **Pre-implementation fixes:** +4 hours
+- **Enhanced testing:** +2 hours
+- **Documentation updates:** +1 hour
+
+**Revised Total:** 10-16 hours (original) + 7 hours (fixes) = **17-23 hours**
+
+### Risk Assessment After Fixes
+
+**Before:** 🟡 MEDIUM Risk  
+**After:** 🟢 LOW Risk
+
+---
+
+## 12. Conclusion
+
+This is a **solid implementation plan** that will significantly improve the developer experience for Ink writers. The proposed features are well-aligned with the existing architecture, and the backward compatibility strategy ensures a smooth rollout.
+
+The main concerns are **integration details** rather than fundamental design flaws. With the recommended fixes applied, this feature set should integrate cleanly into the Break Escape codebase.
+
+**Recommendation:** Proceed with implementation after addressing the critical issues identified in this review.

+
+## Appendix A: Testing Checklist
+
+Use this checklist during implementation:
+
+### Phase 1: Core Parsing
+- [ ] Basic prefix parsing: `"Speaker: Text"`
+- [ ] Case insensitivity: `"speaker:"`, `"SPEAKER:"`, `"Speaker:"`
+- [ ] Multiple spaces: `"Speaker:    Text"`
+- [ ] Colons in text: `"Speaker: The code is: 1234"`
+- [ ] Empty text: `"Speaker: "`

+- [ ] Single NPC: `# hostile:guard_1`
+- [ ] Multiple NPCs: `# hostile:guard_1,guard_2,guard_3`
+- [ ] Wildcard: `# hostile:guard_*`
+- [ ] "All" keyword: `# hostile:all`
+- [ ] Invalid NPC IDs handled gracefully

+# Implementation Plan Updates
+## November 23, 2025
+
+## Summary of Changes
+
+This document describes the enhancements made to the original implementation plan based on new requirements.
+
+---
+
+## 1. Narrator with Character in View
+
+### Problem
+Original plan only supported narrator with NO portrait. Need ability to show narrative text while keeping a specific character's portrait visible.
+
+### Solution
+Extended narrator syntax to support character specification:
+
+```ink
+Narrator[character_id]: Narrative text with character's portrait
+Narrator[]: Narrative text with no portrait (explicit)
+Narrator: Narrative text with no portrait (default)
+```
+
+### Examples
+```ink
+Narrator[test_npc_back]: The technician looks nervous as footsteps approach.
+Narrator[Player]: You feel a knot forming in your stomach.
+Narrator[]: The hallway falls silent and empty.
+```
+
+### Implementation Changes
+- **parseDialogueLine()**: Added regex pattern `/^Narrator\[([A-Za-z_][A-Za-z0-9_]*|)\]:\s+(.+)$/i`
+- **Return object**: Added `narratorCharacter` property (string|null)
+- **buildDialogueBlocks()**: Track `narratorCharacter` in blocks
+- **showDialogue()**: New parameter `narratorCharacter` to show portrait during narrator mode
+- **displayDialogueBlocksSequentially()**: Pass `narratorCharacter` to UI
+
+### Use Cases
+- **Character focus during narration**: Keep attention on specific NPC while describing scene
+- **Internal thoughts**: Show player portrait during narrative internal monologue
+- **Camera direction**: Direct player's attention to specific character
+- **Emotional beats**: Describe character's emotional state while showing their portrait
+
+---
+
+## 2. Default to Main NPC Speaker
+
+### Problem
+Lines without a prefix had unclear default behavior. Should default to main conversation NPC for convenience.
+
+### Solution
+Changed default speaker from "no speaker" to "main conversation NPC":
+
+```ink
+=== greeting ===
+Hello there! // Now defaults to main NPC (whoever you're talking to)
+Player: Hi!
+How can I help? // Also defaults to main NPC
+```
+
+### Implementation Changes
+- **buildDialogueBlocks()**: When no prefix and no current block, use `this.npc.id` (main conversation NPC)
+- **parseDialogueLine()**: Documentation clarified that null speaker means "use default"
+- **Priority order**: Prefix → Current speaker → Main NPC
+
+### Use Cases
+- **Simple conversations**: Less verbose for basic NPC-player exchanges
+- **Backward compatibility**: Works with existing Ink that doesn't use prefixes
+- **Writer convenience**: Don't need prefix for every line in single-NPC conversations
+
+---
+
+## 3. NPC Behavior Tag Enhancements
+
+### Problem
+Current behavior tags (e.g., `# hostile:npc_id`) require explicit NPC ID. This is:
+- Verbose for single-NPC conversations
+- Can't affect multiple NPCs at once
+- No pattern matching for groups of NPCs
+
+### Solution
+Enhanced tag parameter parsing to support:
+
+#### A. No Parameter → Main NPC
+```ink
+test_npc_back: You shouldn't have done that.
+# hostile
+// Makes test_npc_back hostile (main conversation NPC)
+```
+
+#### B. Comma-Separated List
+```ink
+# hostile:guard_1,guard_2,guard_3
+// All three guards become hostile simultaneously
+```
+
+#### C. Wildcard Patterns
+```ink
+# hostile:guard_*
+// All NPCs with IDs starting with "guard_" become hostile
+
+# hostile:receptionist_*,manager_*
+// Multiple patterns supported
+```
+
+#### D. "All" Keyword
+```ink
+# hostile:all
+// All NPCs in the current room become hostile
+```
+
+### Implementation Changes
+
+**New Helper Functions** (in `chat-helpers.js`):
+
+1. **`parseNPCTargets(param, mainNpcId, currentRoomId)`**
+   - Parses tag parameter
+   - Returns array of NPC IDs to affect
+   - Handles empty, single, list, patterns
+
+2. **`getAllNPCsInRoom(roomId)`**
+   - Returns all NPC IDs in a specific room
+   - Used for "all" keyword
+
+3. **`getNPCsByPattern(pattern, roomId)`**
+   - Converts wildcard pattern to regex
+   - Returns matching NPC IDs
+   - Searches current room or all NPCs
+
+**Updated Tag Handlers**:
+- `hostile`: Now uses `parseNPCTargets()`
+- `friendly`: Same enhancement
+- `influence`: Support multiple NPCs
+- All behavior tags: Consistent parameter parsing
+
+### Affected Tags
+- `hostile` - Make NPC(s) aggressive
+- `friendly` - Make NPC(s) non-aggressive
+- `influence` - Modify relationship with NPC(s)
+- `suspicious` - Make NPC(s) wary (future)
+- Any behavior-modifying tags
+
+### Use Cases
+
+**Alarm System:**
+```ink
+=== alarm_triggered ===
+security_guard: INTRUDER DETECTED!
+# hostile:all
+Narrator: Every guard in the building is now hunting you.
+```
+
+**Group Reaction:**
+```ink
+=== insult_everyone ===
+Player: You're all idiots!
+# influence:scientist_*:-20
+Narrator: The entire research team turns hostile.
+# hostile:scientist_*
+```
+
+**Selective Targeting:**
+```ink
+=== bribe_guards ===
+Player: Here's some money for you two.
+# influence:guard_1,guard_2:+30
+guard_1: Thanks! We didn't see anything.
+guard_2: Our lips are sealed.
+```
+
+---
+
+## Testing Requirements
+
+### Narrator with Character Tests
+- [ ] `Narrator[npc_id]:` shows NPC portrait with narrative text
+- [ ] `Narrator[Player]:` shows player portrait with narrative text
+- [ ] `Narrator[]:` explicitly hides portrait
+- [ ] `Narrator:` hides portrait (default)
+- [ ] Invalid character ID falls back gracefully
+- [ ] Narrator styling (italic, centered) applies correctly
+
+### Default Speaker Tests
+- [ ] Lines without prefix default to main NPC
+- [ ] Mixed prefixed/unprefixed lines work correctly
+- [ ] Player can still be specified with prefix
+- [ ] Tag-based detection still works as fallback
+
+### NPC Behavior Tag Tests
+- [ ] `# hostile` (no ID) affects main conversation NPC
+- [ ] `# hostile:npc1,npc2,npc3` affects all listed NPCs
+- [ ] `# hostile:guard_*` matches pattern correctly
+- [ ] `# hostile:all` affects all NPCs in room
+- [ ] Invalid patterns fail gracefully
+- [ ] Multiple patterns work: `# hostile:guard_*,scientist_*`
+- [ ] Empty room handles "all" correctly
+
+---
+
+## Documentation Updates Needed
+
+### Ink Writer Guide
+- Add narrator with character syntax examples
+- Document default speaker behavior
+- Add NPC behavior tag enhancements section
+- Include pattern matching examples
+- Add "Common Patterns" section with use cases
+
+### Code Comments
+- Update `parseDialogueLine()` JSDoc
+- Update `showDialogue()` JSDoc
+- Document `parseNPCTargets()` thoroughly
+- Add inline comments for pattern matching logic
+
+### Architecture Docs
+- Update NPC behavior tag format specification
+- Document narrator character view system
+- Add default speaker resolution flowchart
+
+---
+
+## Timeline Impact
+
+**Original Estimate:** 8-13 hours
+**New Estimate:** 10-16 hours
+
+**Additional Time:**
+- Phase 4 (Narrator): +0.5 hours (narrator character support)
+- Phase 6 (NPC Tags): +2-3 hours (new phase)
+- Phase 7 (Docs): +0.5 hours (additional documentation)
+
+---
+
+## Backward Compatibility
+
+✅ **All changes are backward compatible:**
+
+1. **Narrator**: Original `Narrator:` syntax still works
+2. **Default Speaker**: Unprefixed lines still work (now defaults to main NPC instead of undefined)
+3. **NPC Tags**: Existing tags with explicit IDs work unchanged
+
+❌ **No breaking changes** - all existing Ink files will work exactly as before.
+
+---
+
+## Future Enhancements (Not in This Plan)
+
+### Background Image Control
+```ink
+Background[office_night.png]: The lights dim as evening falls.
+```
+
+### Multiple Character Portraits
+```ink
+Group[test_npc_back,test_npc_front]: The two technicians exchange glances.
+```
+
+### Camera/Focus Control
+```ink
+Focus[test_npc_back]: The camera zooms in on their worried expression.
+```
+
+### Emotion/Expression Control
+```ink
+test_npc_back[worried]: I'm not sure this is a good idea.
+```
+
+These would require additional UI work and are deferred to future iterations.

+# Planning Documents Update Summary
+## Addressing REVIEW1 Findings
+
+**Date:** November 23, 2025  
+**Status:** All review issues addressed
+
+---
+
+## Overview
+
+The planning documents have been comprehensively updated to address all 12 critical and high-priority issues identified in REVIEW1.md, plus numerous medium and low priority items. The revised plans are now self-contained and production-ready.
+
+---
+
+## Critical Issues Addressed
+
+### 1. ✅ Function Naming Conflict
+
+**Issue:** Plan referenced `buildDialogueBlocks()` but codebase has `createDialogueBlocks()`
+
+**Resolution:**
+- Updated IMPLEMENTATION_PLAN_REVISED.md to use `createDialogueBlocks()` (existing name)
+- Avoids breaking change and reduces migration friction
+- Clear note about naming consistency in Phase 0
+
+### 2. ✅ determineSpeaker() Not Used
+
+**Issue:** Method exists but isn't called; speaker detection is hardcoded in `createDialogueBlocks()`
+
+**Resolution:**
+- Created Phase 0 (Pre-Implementation Refactoring) focusing on consolidating speaker detection
+- Requires refactoring `createDialogueBlocks()` to call `determineSpeaker()`
+- Makes `determineSpeaker()` the single source of truth for all speaker detection
+- Includes explicit TODO for Phase 0 completion
+
+### 3. ✅ Regex Security Issue
+
+**Issue:** NPC pattern matching vulnerable to regex injection attacks
+
+**Resolution:**
+- IMPLEMENTATION_PLAN_REVISED.md (Phase 6.1) adds comprehensive input sanitization
+- Added try/catch error handling around regex compilation
+- Escapes all regex special characters except `*`
+- Validates patterns before compiling to regex
+- Example attack patterns are now blocked gracefully
+
+---
+
+## High Priority Issues Addressed
+
+### 4. ✅ Empty Dialogue Text Validation
+
+**Issue:** No handling for `"Speaker: "` (empty text after prefix)
+
+**Resolution:**
+- `parseDialogueLine()` implementation (Phase 1.1) validates all dialogue text
+- Empty text lines logged with warnings and rejected as unprefixed
+- Prevents silent failures and mysterious display issues
+- Detailed validation logic documented in code
+
+### 5. ✅ NPC ID Validation in Lists
+
+**Issue:** Comma-separated NPC lists not validated to ensure NPCs exist
+
+**Resolution:**
+- `parseNPCTargets()` function (Phase 6.1) validates each NPC ID
+- Invalid NPC IDs logged with warnings but don't break behavior
+- Gracefully falls back to main NPC if all IDs invalid
+- Detailed in implementation with example error messages
+
+### 6. ✅ Room Context Missing
+
+**Issue:** How does `parseNPCTargets()` get current room ID?
+
+**Resolution:**
+- Updated Phase 6 to use `window.currentRoom` or `window.player?.currentRoom` pattern
+- Consistent with existing codebase patterns (window globals)
+- Fallback to main NPC if room context unavailable
+- Documented in Phase 6.1 implementation notes
+
+---
+
+## Medium Priority Issues Addressed
+
+### 7. ✅ Performance Optimization Noted
+
+**Issue:** Line-by-line parsing slower than tag-based grouping
+
+**Resolution:**
+- OVERVIEW_REVISED.md documents performance expectations
+- Typical conversation: ~1ms overhead (negligible)
+- Clear guidance: cache not needed for typical use
+- Performance testing included in Phase 5 checklist
+
+### 8. ✅ Memory Leak Fixed
+
+**Issue:** `charactersWithParallax` Set never cleared
+
+**Resolution:**
+- Phase 0.3 explicitly includes cleanup of `charactersWithParallax`
+- Added `destroy()` method documentation
+- Included in acceptance criteria for Phase 0
+
+### 9. ✅ Race Condition Prevention
+
+**Issue:** No locking during dialogue processing
+
+**Resolution:**
+- Phase 0.2 adds dialogue state locking: `this.isProcessingDialogue`
+- Prevents rapid input causing overlapping dialogue processing
+- Documented with before/after code examples
+- Included in acceptance criteria
+
+---
+
+## Edge Cases & Error Handling
+
+### 10. ✅ Comprehensive Edge Case Documentation
+
+**Issue:** Missing tests for malformed input, Unicode, very long lines
+
+**Resolution:**
+- IMPLEMENTATION_PLAN_REVISED.md Phase 5 includes expanded test checklist
+- Added explicit test cases:
+  - Malformed prefixes: `"Player :"`, `"Player"`, `": Text"`
+  - Empty text after prefix: `"Player: "`
+  - Special characters and Unicode: `"🎭: Text"`, `"こんにちは: Text"`
+  - Very long lines (5000+ characters)
+- Testing strategy emphasizes regression prevention
+
+### 11. ✅ Malformed Input Handling
+
+**Issue:** No specification of behavior for invalid prefixes
+
+**Resolution:**
+- IMPLEMENTATION_PLAN_REVISED.md Phase 1 details handling:
+  - Invalid speaker IDs → no prefix (line treated as unprefixed)
+  - Empty text after prefix → no prefix (logged as warning)
+  - Malformed patterns → rejected gracefully
+- `normalizeSpeakerId()` validates all speaker IDs
+- Console warnings for all edge cases
+
+### 12. ✅ Character Lookup Edge Cases
+
+**Issue:** What if character data missing?
+
+**Resolution:**
+- IMPLEMENTATION_PLAN_REVISED.md Phase 4.1 shows defensive programming
+- Explicit null checks: `this.characters?.[characterId]`
+- Player character special case handling
+- Fallback to hide portrait if character missing
+- Graceful degradation rather than errors
+
+---
+
+## Backward Compatibility
+
+### ✅ Full Backward Compatibility Maintained
+
+- All method signatures add **optional parameters only** (no breaking changes)
+- Existing 20+ `showDialogue()` call sites work without modification
+- Tag-based speaker detection remains as fallback
+- No changes to Ink compiler or runtime
+- No Rails backend changes needed
+
+**Verification:**
+- Default parameter values preserve existing behavior
+- Prefix format is **additive** (lines can stay unprefixed)
+- All existing conversations work unchanged
+- Mixed old/new syntax supported
+
+---
+
+## Architectural Improvements
+
+### ✅ Code Consolidation
+
+**Before:** Speaker detection in two places (duplicated, inconsistent)
+```
+determineSpeaker() [unused]  +  createDialogueBlocks() [inline hardcoded]
+```
+
+**After:** Speaker detection centralized (maintainable, consistent)
+```
+determineSpeaker() [primary]  ←  createDialogueBlocks() [calls it]
+```
+
+### ✅ Refactoring Enables Future Features
+
+Phase 0 consolidation makes it easy to add in future:
+- Emotion variants: `Speaker[emotion]: Text`
+- Location hints: `Speaker@location: Text`
+- Sound effects: `Sound[file.mp3]: Text`
+- Background changes: `Background[image.png]: Text`

+## Next Steps for Implementation
+
+1. **Review** these revised plans with team/stakeholders
+2. **Approve** the implementation approach
+3. **Schedule** Phase 0 (refactoring) first - most critical
+4. **Begin** implementation following phases 1-7 in order
+5. **Run** comprehensive test checklist at each phase
+6. **Get** writer feedback on QUICK_REFERENCE_REVISED.md
+7. **Deploy** with confidence knowing all issues are addressed
+
+---
+
+## Questions & Clarifications
+
+**Q: Should we rename IMPLEMENTATION_PLAN_REVISED.md to IMPLEMENTATION_PLAN.md?**  
+A: Yes, after stakeholder approval. The _REVISED suffix is temporary for comparison purposes.
+
+**Q: What about the old documents?**  
+A: Keep them as reference. They document the design evolution. Archive them to `review/` if needed.
+
+**Q: Is Phase 0 really critical?**  
+A: Yes. Without consolidating speaker detection, the codebase becomes harder to maintain. It's small work now, saves pain later.
+
+**Q: Can we skip any phases?**  
+A: No, they're sequential dependencies. Phase 1 needs Phase 0's consolidation. Phase 3 needs Phase 1's parsing, etc.
+
+**Q: When should we implement?**  
+A: After Phase 0, the remaining phases can proceed independently in parallel if needed. Phase 5 (testing) can overlap.
+
+---
+
+## Conclusion
+
+All issues from REVIEW1 have been systematically addressed and incorporated into comprehensive, self-contained planning documents. The plans are now ready for implementation with clear phasing, acceptance criteria, and risk mitigation strategies.
+
+The refactoring phase (Phase 0) is the critical foundation - complete it first before moving to feature implementation. All other phases build on that solid foundation.
