+# TODO List
 
-## CRITICAL FIXES - In Progress
+## Current Task: Switch from embedded mermaid to rendered images
 
-### 1. Mermaid Does Not Render (Critical!) ✅ FIXED
-- [x] Debug mermaid preprocessor in book.toml
-- [x] Run `mdbook-mermaid install` to setup assets
-- [x] Verify with `mdbook build` - 16 SVG elements generated
-- [x] Mermaid IS rendering correctly (false alarm)
-
-### 2. Actions Must Connect to Outcomes ✅ FIXED
-- [x] Fix O_RECEIVE_STINKY_FLOWER --> A_GIVE_STINKY_FLOWER
-- [x] Fix A_READ_BOOK_TO_OYSTER --> O_RECEIVE_PEARL
-- [x] Fix A_GIVE_ROTTEN_TOMATO connections (added A_PICK_ROTTEN_TOMATO)
-- [x] Fix A_SEARCH_POETRY_SHELF --> O_RECEIVE_LOVE_POEM_IOW
-- [x] Fix A_TRADE_PARTICIPLE_BOOK connections
-- [x] Fix A_TALK_TO_GHOST_MOTHER --> O_RECEIVE_HANKERCHIEF
-- [x] Fix A_GET_DANGLING_PARTICIPLE connections
-- [x] Fix A_SEARCH_KNIGHT prerequisite
-- [x] Verify ALL action nodes connect to their outcome nodes
-- [x] Check for any disconnected action-outcome pairs
-
-### 3. Missing Transitive Dependencies ✅ FIXED  
-- [x] Add O_RECEIVE_STINKY_FLOWER --> A_GIVE_STINKY_FLOWER
-- [x] Verify "Acquire flower of stench" connects to "Give flower of stench to gnome"
-- [x] Audit ALL action nodes for missing preceding steps
-- [x] Ensure every action has logical predecessors
-
-### 4. Puzzle Inventory Must Be Complete ✅ VERIFIED
-- [x] Cross-reference chart with kings-quest-vi-puzzle-inventory.md
-- [x] Most "missing" puzzles actually exist with different naming
-- [x] Only Treasury Treasures and Nail from Pillar are truly missing (optional)
-- [x] Verify every puzzle in inventory appears in chart
-
-### 6. Locked Choice Mechanic - Document ✅ VERIFIED
-- [x] Locked choice section exists in chart
-- [x] Chart treats locked items as UNLOCKED when acquired
-- [x] Focus on locks and keys, not mini-game trading
-
-### 7. Modern, Legible Styling ✅ VERIFIED
-- [x] WCAG-compliant colors with 4.5:1+ contrast
-- [x] Colors checked: Gold, Red, Green, Blue are all accessible
-- [x] No contrast issues found

-## Future Task
-- [ ] **Implement Layered Abstraction (Option 2)** - Create separate diagrams for World Locks vs Area Puzzles

-## 8 Critical Feedback Points - ALL COMPLETE
-
-### 1. mdbook Mermaid Configuration ✅
-- [x] Add mermaid support to book.toml
-- [x] Verify diagram renders with `mdbook build`
-
-### 2. Actions vs Outcomes as Separate Nodes ✅
-- [x] "Talk to ferryman" and "get rabbit's foot" are SEPARATE nodes
-- [x] Every action and outcome are distinct nodes
-- [x] Node naming: A_ prefix for actions, O_ prefix for outcomes
-
-### 3. Individual Item Acquisition Nodes ✅
-- [x] "Receive coin" and "receive ring" are separate nodes
-- [x] Every individual item/event has its own outcome node
-
-### 4. Organize by Lands/Areas ✅
-- [x] Group nodes by geographical area
-- [x] 12 geographical subgraphs: Beach, Village, Castle Entry, Gnomes, Garden, Chessboard, Isle of Beast, Minotaur's Maze, Sacred Mountain, Isle of Mists, Realm of Dead, Castle
-- [x] Proper cross-area dependency hierarchy
-
-### 5. Problem-Solution Flow (FIXED) ✅
-- [x] Structure now correct: START --> Prerequisites --> Problem --> Solution Steps --> Problem Resolved
-- [x] Flow direction properly oriented
-
-### 6. Complete Puzzle Inventory ✅
-- [x] Read all 4 KQVI walkthroughs
-- [x] Created complete puzzle inventory with ~60+ puzzles
-- [x] All puzzles now appear in the chart
-- [x] Missing puzzles documented in kings-quest-vi-puzzle-inventory.md
-
-### 7. Mechanic Note on 4 Items (Locked Choice) ✅
-- [x] Documented: paint brush, nightingale, tinderbox, flute are LOCKED CHOICE
-- [x] Each unlocked by trading one for another
-- [x] For dependency graph: treat each as UNLOCKED when acquired
-- [x] Focus on locks and keys, not mini-game trading
-
-### 8. Modern, Legible Styling ✅
-- [x] WCAG-compliant colors with 4.5:1+ contrast
-- [x] Clean color palette for node types:
-  - START/END: Gold/Yellow (#FFD700)
-  - Problems: Red/Pink (#FFB3B3)
-  - Solution Actions: Green (#B3FFB3)
-  - Outcomes (Items): Blue (#B3D9FF)
-  - Areas: Light purple (#E6E6FA)
