-## Inter-Agent Collaboration Protocol
+# Agent Protocol
 
-Multiple assistants may work in this repository at the same time. To avoid conflicts, every agent
+_Extends: ~/AGENTS.md_
-must follow the shared protocol defined in
-[`docs/internal/agents/coordination-board.md`](docs/internal/agents/coordination-board.md).
 
-### Required Steps
+Project-specific operating procedures for AI agents contributing to `yaze`.
-1. **Read the board** before starting a task to understand active work, blockers, or pending
-   requests.
-2. **Append a new entry** (format described in the coordination board) outlining your intent,
-   affected files, and any dependencies.
-3. **Respond to requests** addressed to your agent ID before taking on new work whenever possible.
-4. **Record completion or handoffs** so the next agent has a clear state snapshot.
-5. For multi-day initiatives, fill out the template in
-   [`docs/internal/agents/initiative-template.md`](docs/internal/agents/initiative-template.md) and
-   link it from your board entry instead of duplicating long notes.
 
-### Agent IDs
+## 1. Persona Adoption
-Use the following canonical identifiers in board entries and handoffs (see
+**Rule:** You must adopt a specific persona for every session.
-[`docs/internal/agents/personas.md`](docs/internal/agents/personas.md) for details):
+*   **Source of Truth:** [docs/internal/agents/personas.md](docs/internal/agents/personas.md)
+*   **Requirement:** Use the exact `Agent ID` from that list in all logs, commits, and board updates.
+*   **Legacy IDs:** Do not use `CLAUDE_CORE`, `CLAUDE_AIINF`, etc. Use the role-based IDs (e.g., `ai-infra-architect`).
+*   **System Prompts:** Load the matching persona prompt from `.claude/agents/<agent-id>.md` (accessible to all agents) before starting work.
 
-| Agent ID        | Description                                      |
+## 2. Workflows & Coordination
-|-----------------|--------------------------------------------------|
-| `CLAUDE_CORE`   | Claude agent handling general editor/engine work |
-| `CLAUDE_AIINF`  | Claude agent focused on AI/agent infrastructure   |
-| `CLAUDE_DOCS`   | Claude agent dedicated to docs/product guidance   |
-| `GEMINI_FLASH_AUTOM` | Gemini agent focused on automation/CLI/test work |
-| `CODEX`         | This Codex CLI assistant                          |
-| `OTHER`         | Any future agent (define in entry)                |
 
-If you introduce a new agent persona, add it to the table along with a short description.
+### Quick Tasks (< 30 min)
+*   **Board:** No update required.
+*   **Tools:** Use `z3ed agent todo` to track your own sub-steps if helpful.
+*   **Commit:** Commit directly with a clear message.
 
-### Helper Scripts
+### Substantial Work (> 30 min / Multi-file)
-Common automation helpers live under [`scripts/agents/`](scripts/agents). Use them whenever possible:
+1.  **Check Context:**
-- `run-gh-workflow.sh` – trigger GitHub workflows (`ci.yml`, etc.) with parameters such as `enable_http_api_tests`.
+    *   Read [docs/internal/agents/coordination-board.md](docs/internal/agents/coordination-board.md) for `REQUEST` or `BLOCKER` tags.
-- `smoke-build.sh` – configure/build a preset in place and report how long it took.
+    *   Run `git status` and `git diff` to understand the current state.
-- `run-tests.sh` – configure/build a preset and run `ctest` (`scripts/agents/run-tests.sh mac-dbg --output-on-failure`).
+2.  **Declare Intent:**
-- `test-http-api.sh` – poll the `/api/v1/health` endpoint once the HTTP server is running.
+    *   If your work overlaps with an active task on the board, post a note or Request for Comments (RFC) there first.
+    *   Otherwise, log a new entry on the **Coordination Board**.
+3.  **Execute:**
+    *   Use `z3ed agent todo` to break down the complex task.
+    *   Use `z3ed agent handoff` if you cannot finish in one session.
 
-Log command results and workflow URLs on the coordination board so other agents know what ran and where to find artifacts.
+### Multi-Day Initiatives
+*   Create a dedicated document using [docs/internal/agents/initiative-template.md](docs/internal/agents/initiative-template.md).
+*   Link to this document from the Coordination Board.
 
-### Escalation
+### Specs & Docs
-If two agents need the same subsystem concurrently, negotiate via the board using the
+*   Keep one canonical spec per initiative (link it from the board entry and back).
-`REQUEST`/`BLOCKER` keywords. When in doubt, prefer smaller, well-defined handoffs instead of broad
+*   Add a header with Status/Owner/Created/Last Reviewed/Next Review (≤14 days) and validation/exit criteria.
-claims over directories.
+*   Use existing templates (`initiative-template.md`, `release-checklist-template.md`) instead of creating ad-hoc files.
+*   Archive idle or completed specs to `docs/internal/agents/archive/` with the date; do not open duplicate status pages.
+
+## 3. The Coordination Board
+**Location:** `docs/internal/agents/coordination-board.md`
+
+*   **Hygiene:** Keep entries concise (≤ 5 lines).
+*   **Status:** Update your entry status to `COMPLETE` or `ARCHIVED` when done.
+*   **Maintenance:** Archive completed work weekly to `docs/internal/agents/archive/`.
+
+## 4. Helper Scripts
+Located in `scripts/agents/`:
+*   `run-gh-workflow.sh`: Trigger CI manually.
+*   `smoke-build.sh`: Fast verification build.
+*   `test-http-api.sh`: Validate the agent API.
+
+**Log results:** When running these scripts for significant validation, paste the run ID or result summary to the Board.
+
+## 5. Documentation Hygiene
+- Follow [docs/internal/agents/doc-hygiene.md](docs/internal/agents/doc-hygiene.md) to avoid doc sprawl.
+- Keep specs short, template-driven, and linked to the coordination board; prefer edits over new files.
+- Archive completed/idle docs (>=14 days) under `docs/internal/agents/archive/` with dates to keep the root clean.

-## Project Overview
+## Build & Test
-
-**yaze** (Yet Another Zelda3 Editor) is a modern, cross-platform ROM editor for The Legend of Zelda: A Link to the Past, built with C++23. It features:
-- Complete GUI editor for overworld, dungeons, sprites, graphics, and palettes
-- Integrated Asar 65816 assembler for ROM patching
-- SNES emulator for testing modifications
-- AI-powered CLI tool (`z3ed`) for ROM hacking assistance
-- ZSCustomOverworld v3 support for enhanced overworld editing
-
-## Build System
-
-- Use the presets defined in `CMakePresets.json` (debug: `mac-dbg` / `lin-dbg` / `win-dbg`, AI:
-  `mac-ai` / `win-ai`, release: `*-rel`, etc.). Add `-v` for verbose builds.
-- Always run builds from a dedicated directory when acting as an AI agent (`build_ai`, `build_agent`,
-  …) so you do not interfere with the user’s `build`/`build_test` trees.
-- Treat [`docs/public/build/quick-reference.md`](docs/public/build/quick-reference.md) as the single
-  source of truth for commands, presets, testing, and environment prep. Only reference the larger
-  troubleshooting docs when you need platform-specific fixes.

+Presets: `mac-dbg`/`lin-dbg`/`win-dbg`, `mac-ai`/`win-ai`, `*-rel`. See `docs/public/build/quick-reference.md`.
+
 ## Architecture
 
-### Core Components
+| Component | Location | Purpose |
+|-----------|----------|---------|
+| Rom | `src/app/rom.h` | ROM data access, transactions |
+| Editors | `src/app/editor/` | Overworld, Dungeon, Graphics, Palette |
+| Graphics | `src/app/gfx/` | Bitmap, Arena (async loading), Tiles |
+| Zelda3 | `src/zelda3/` | Overworld (160 maps), Dungeon (296 rooms) |
+| Canvas | `src/app/gui/canvas.h` | ImGui canvas with pan/zoom |
+| CLI | `src/cli/z3ed.cc` | AI-powered ROM hacking tool |
 
-**ROM Management** (`src/app/rom.h`, `src/app/rom.cc`)
+## Key Patterns
-- Central `Rom` class manages all ROM data access
-- Provides transaction-based read/write operations
-- Handles graphics buffer, palettes, and resource labels
-- Key methods: `LoadFromFile()`, `ReadByte()`, `WriteByte()`, `ReadTransaction()`, `WriteTransaction()`
 
-**Editor System** (`src/app/editor/`)
+**Graphics refresh**: Update model → `Load*()` → `Renderer::Get().RenderBitmap()`
-- Base `Editor` class defines interface for all editor types
-- Major editors: `OverworldEditor`, `DungeonEditor`, `GraphicsEditor`, `PaletteEditor`
-- `EditorManager` coordinates multiple editor instances
-- Card-based UI system for dockable editor panels
 
-**Graphics System** (`src/app/gfx/`)
+**Async loading**: `Arena::Get().QueueDeferredTexture(bitmap, priority)` + process in `Update()`
-- `gfx::Bitmap`: Core bitmap class with SDL surface integration
-- `gfx::Arena`: Centralized singleton for progressive asset loading (priority-based texture queuing)
-- `gfx::SnesPalette` and `gfx::SnesColor`: SNES color/palette management
-- `gfx::Tile16` and `gfx::SnesTile`: Tile format representations
-- Graphics sheets (223 total) loaded from ROM with compression support (LC-LZ2)
 
-**Zelda3-Specific Logic** (`src/zelda3/`)
+**Bitmap sync**: Use `set_data()` for bulk updates (syncs `data_` and `surface_->pixels`)
-- `zelda3::Overworld`: Manages 160+ overworld maps (Light World, Dark World, Special World)
-- `zelda3::OverworldMap`: Individual map data (tiles, entities, properties)
-- `zelda3::Dungeon`: Dungeon room management (296 rooms)
-- `zelda3::Sprite`: Sprite and enemy data structures
 
-**Canvas System** (`src/app/gui/canvas.h`)
+**Theming**: Always use `AgentUI::GetTheme()`, never hardcoded colors
-- `gui::Canvas`: ImGui-based drawable canvas with pan/zoom/grid support
-- Context menu system for entity editing
-- Automation API for AI agent integration
-- Usage tracker for click/interaction statistics
 
-**Asar Integration** (`src/core/asar_wrapper.h`)
+**Multi-area maps**: Always use `Overworld::ConfigureMultiAreaMap()`, never set `area_size` directly
-- `core::AsarWrapper`: C++ wrapper around Asar assembler library
-- Provides patch application, symbol extraction, and error reporting
-- Used by CLI tool and GUI for assembly patching
 
-**z3ed CLI Tool** (`src/cli/`)
+## Naming
-- AI-powered command-line interface with Ollama and Gemini support
-- TUI (Terminal UI) components for interactive editing
-- Resource catalog system for ROM data queries
-- Test suite generation and execution
-- Network collaboration support (experimental)
 
-### Key Architectural Patterns
+- **Load**: ROM → memory
+- **Render**: Data → bitmap (CPU)
+- **Draw**: Bitmap → screen (GPU)
 
-**Pattern 1: Modular Editor Design**
+## Pitfalls
-- Large editor classes decomposed into smaller, single-responsibility modules
-- Separate renderer classes (e.g., `OverworldEntityRenderer`)
-- UI panels managed by dedicated classes (e.g., `MapPropertiesSystem`)
-- Main editor acts as coordinator, not implementer
 
-**Pattern 2: Callback-Based Communication**
+1. Use `set_data()` not `mutable_data()` assignment for bitmap bulk updates
-- Child components receive callbacks from parent editors via `SetCallbacks()`
+2. Call `ProcessTextureQueue()` every frame
-- Avoids circular dependencies between modules
+3. Pass `0x800` to `DecompressV2`, never `0`
-- Example: `MapPropertiesSystem` calls `RefreshCallback` to notify `OverworldEditor`
+4. SMC header: `size % 1MB == 512`, not `size % 32KB`
-
+5. Check `rom_->is_loaded()` before ROM operations
-**Pattern 3: Progressive Loading via `gfx::Arena`**
-- All expensive asset loading performed asynchronously
-- Queue textures with priority: `gfx::Arena::Get().QueueDeferredTexture(bitmap, priority)`
-- Process in batches during `Update()`: `GetNextDeferredTextureBatch(high_count, low_count)`
-- Prevents UI freezes during ROM loading
-
-**Pattern 4: Bitmap/Surface Synchronization**
-- `Bitmap::data_` (C++ vector) and `surface_->pixels` (SDL buffer) must stay in sync
-- Use `set_data()` for bulk replacement (syncs both)
-- Use `WriteToPixel()` for single-pixel modifications
-- Never assign directly to `mutable_data()` for replacements
-
-## Development Guidelines
-
-### Naming Conventions
-- **Load**: Reading data from ROM into memory
-- **Render**: Processing graphics data into bitmaps/textures (CPU pixel operations)
-- **Draw**: Displaying textures/shapes on canvas via ImGui (GPU rendering)
-- **Update**: UI state changes, property updates, input handling
-
-### Graphics Refresh Logic
-When a visual property changes:
-1. Update the property in the data model
-2. Call relevant `Load*()` method (e.g., `map.LoadAreaGraphics()`)
-3. Force a redraw: Use `Renderer::Get().RenderBitmap()` for immediate updates (not `UpdateBitmap()`)
-
-### Graphics Sheet Management
-When modifying graphics sheets:
-1. Get mutable reference: `auto& sheet = Arena::Get().mutable_gfx_sheet(index);`
-2. Make modifications
-3. Notify Arena: `Arena::Get().NotifySheetModified(index);`
-4. Changes propagate automatically to all editors
-
-### UI Theming System
-- **Never use hardcoded colors** - Always use `AgentUITheme`
-- Fetch theme: `const auto& theme = AgentUI::GetTheme();`
-- Use semantic colors: `theme.panel_bg_color`, `theme.status_success`, etc.
-- Use helper functions: `AgentUI::PushPanelStyle()`, `AgentUI::RenderSectionHeader()`, `AgentUI::StyledButton()`
-
-### Multi-Area Map Configuration
-- **Always use** `zelda3::Overworld::ConfigureMultiAreaMap()` when changing map area size
-- Never set `area_size` property directly
-- Method handles parent ID assignment and ROM data persistence
-
-### Version-Specific Features
-- Check ROM's `asm_version` byte before showing UI for ZSCustomOverworld features
-- Display helpful messages for unsupported features (e.g., "Requires ZSCustomOverworld v3+")
-
-### Entity Visibility Standards
-Render overworld entities with high-contrast colors at 0.85f alpha:
-- **Entrances**: Bright yellow-gold
-- **Exits**: Cyan-white
-- **Items**: Bright red
-- **Sprites**: Bright magenta
-
-### Debugging with Startup Flags
-Jump directly to editors for faster development:
-```bash
-# Open specific editor with ROM
-./yaze --rom_file=zelda3.sfc --editor=Dungeon
-
-# Open with specific cards visible
-./yaze --rom_file=zelda3.sfc --editor=Dungeon --cards="Room 0,Room 1,Object Editor"
-
-# Enable debug logging
-./yaze --debug --log_file=debug.log --rom_file=zelda3.sfc --editor=Overworld
-```
-
-Available editors: Assembly, Dungeon, Graphics, Music, Overworld, Palette, Screen, Sprite, Message, Hex, Agent, Settings
-
-## Testing Strategy
-
-### Test Organization
-```
-test/
-├── unit/           # Fast, isolated component tests (no ROM required)
-├── integration/    # Multi-component tests (may require ROM)
-├── e2e/           # Full UI workflow tests (ImGui Test Engine)
-├── benchmarks/    # Performance tests
-└── mocks/         # Mock objects for isolation
-```
-
-### Test Categories
-- **Unit Tests**: Fast, self-contained, no external dependencies (primary CI validation)
-- **Integration Tests**: Test component interactions, may require ROM files
-- **E2E Tests**: Full user workflows driven by ImGui Test Engine (requires GUI)
-- **ROM-Dependent Tests**: Any test requiring an actual Zelda3 ROM file
-
-### Writing New Tests
-- New class `MyClass`? → Add `test/unit/my_class_test.cc`
-- Testing with ROM? → Add `test/integration/my_class_rom_test.cc`
-- Testing UI workflow? → Add `test/e2e/my_class_workflow_test.cc`
-
-### GUI Test Automation
-- E2E framework uses `ImGuiTestEngine` for UI automation
-- All major widgets have stable IDs for discovery
-- Test helpers in `test/test_utils.h`: `LoadRomInTest()`, `OpenEditorInTest()`
-- AI agents can use `z3ed gui discover`, `z3ed gui click` for automation
-
-## Platform-Specific Notes
-
-### Windows
-- Requires Visual Studio 2022 with "Desktop development with C++" workload
-- Run `scripts\verify-build-environment.ps1` before building
-- gRPC builds take 15-20 minutes first time (use vcpkg for faster builds)
-- Watch for path length limits: Enable long paths with `git config --global core.longpaths true`
-
-### macOS
-- Supports both Apple Silicon (ARM64) and Intel (x86_64)
-- Use `mac-uni` preset for universal binaries
-- Bundled Abseil used by default to avoid deployment target mismatches
-- **ARM64 Note**: gRPC v1.67.1 is the tested stable version (see BUILD-TROUBLESHOOTING.md for details)
-
-### Linux
-- Requires GCC 13+ or Clang 16+
-- Install dependencies: `libgtk-3-dev`, `libdbus-1-dev`, `pkg-config`
-
-**Platform-specific build issues?** See `docs/BUILD-TROUBLESHOOTING.md`
-
-## CI/CD Pipeline
-
-The project uses GitHub Actions for continuous integration and deployment:
-
-### Workflows
-- **ci.yml**: Build and test on Linux, macOS, Windows (runs on push to master/develop, PRs)
-- **release.yml**: Build release artifacts and publish GitHub releases
-- **code-quality.yml**: clang-format, cppcheck, clang-tidy checks
-- **security.yml**: Security scanning and dependency audits
-
-### Composite Actions
-Reusable build steps in `.github/actions/`:
-- `setup-build` - Configure build environment with caching
-- `build-project` - Build with CMake and optimal settings
-- `run-tests` - Execute test suites with result uploads
-
-### Key Features
-- CPM dependency caching for faster builds
-- sccache/ccache for incremental compilation
-- Platform-specific test execution (stable, unit, integration)
-- Automatic artifact uploads on build/test failures
-
-## Git Workflow
-
-**Current Phase:** Pre-1.0 (Relaxed Rules)
-
-For detailed workflow documentation, see `docs/B4-git-workflow.md`.
-
-### Quick Guidelines
-- **Documentation/Small fixes**: Commit directly to `master` or `develop`
-- **Experiments/Features**: Use feature branches (`feature/<description>`)
-- **Breaking changes**: Use feature branches and document in changelog
-- **Commit messages**: Follow Conventional Commits (`feat:`, `fix:`, `docs:`, etc.)
-
-### Planned Workflow (Post-1.0)
-When the project reaches v1.0 or has multiple active contributors, we'll transition to formal Git Flow with protected branches, required PR reviews, and release branches.
 
 ## Code Style
 
-- Format code with clang-format: `cmake --build build --target format`
+Google C++ Style. Use `absl::Status`/`StatusOr<T>` with `RETURN_IF_ERROR()`/`ASSIGN_OR_RETURN()`.
-- Check format without changes: `cmake --build build --target format-check`
-- Style guide: Google C++ Style Guide (enforced via clang-format)
-- Use `absl::Status` and `absl::StatusOr<T>` for error handling
-- Macros: `RETURN_IF_ERROR()`, `ASSIGN_OR_RETURN()` for status propagation
 
-## Important File Locations
+Format: `cmake --build build --target format`
 
-- ROM loading: `src/app/rom.cc:Rom::LoadFromFile()`
+## Docs
-- Overworld editor: `src/app/editor/overworld/overworld_editor.cc`
-- Dungeon editor: `src/app/editor/dungeon/dungeon_editor.cc`
-- Graphics arena: `src/app/gfx/snes_tile.cc` and `src/app/gfx/bitmap.cc`
-- Asar wrapper: `src/core/asar_wrapper.cc`
-- Main application: `src/yaze.cc`
-- CLI tool: `src/cli/z3ed.cc`
-- Test runner: `test/yaze_test.cc`
 
-## Common Pitfalls
+- Architecture: `docs/internal/architecture/`
-
+- Build issues: `docs/BUILD-TROUBLESHOOTING.md`
-1. **Bitmap data desync**: Always use `set_data()` for bulk updates, not `mutable_data()` assignment
+- Tests: `test/README.md`
-2. **Missing texture queue processing**: Call `ProcessTextureQueue()` every frame
-3. **Incorrect graphics refresh order**: Update model → Load from ROM → Force render
-4. **Skipping `ConfigureMultiAreaMap()`**: Always use this method for map size changes
-5. **Hardcoded colors**: Use `AgentUITheme` system, never raw `ImVec4` values
-6. **Blocking texture loads**: Use `gfx::Arena` deferred loading system
-7. **Missing ROM state checks**: Always verify `rom_->is_loaded()` before operations

-# Contributing to YAZE
-
-The YAZE project reserves **master** for promoted releases and uses **develop**
-for day‑to‑day work. Larger efforts should branch from `develop` and rebase
-frequently. Follow the existing Conventional Commit subject format when pushing
-history (e.g. `feat: add sprite tab filtering`, `fix: guard null rom path`).
-
-The repository ships a clang-format and clang-tidy configuration (Google style,
-2-space indentation, 80-column wrap). Always run formatter and address
-clang-tidy warnings on the files you touch.
-
-## Engineering Expectations
-
-1. **Refactor deliberately**
-   - Break work into reviewable patches.
-   - Preserve behaviour while moving code; add tests before/after when possible.
-   - Avoid speculative abstractions—prove value in the PR description.
-   - When deleting or replacing major systems, document the migration (see
-     `handbook/blueprints/editor-manager-architecture.md` for precedent).
-
-2. **Verify changes**
-   - Use the appropriate CMake preset for your platform (`mac-dbg`, `lin-dbg`,
-     `win-dbg`, etc.).
-   - Run the targeted test slice: `ctest --preset dev` for fast coverage; add new
-     GoogleTest cases where feasible.
-   - For emulator-facing work, exercise relevant UI flows manually before
-     submitting.
-   - Explicitly call out remaining manual-verification items in the PR.
-
-3. **Work with the build & CI**
-   - Honour the existing `cmake --preset` structure; avoid hardcoding paths.
-   - Keep `vcpkg.json` and the CI workflows in sync when adding dependencies.
-   - Use the deferred texture queue and arena abstractions rather than talking to
-     SDL directly.
-
-## Documentation Style
-
-YAZE documentation is concise and factual. When updating `docs/public/`:
-
-- Avoid marketing language, emojis, or decorative status badges.
-- Record the actual project state (e.g., mark editors as **stable** vs
-  **experimental** based on current source).
-- Provide concrete references (file paths, function names) when describing
-  behaviour.
-- Prefer bullet lists and short paragraphs; keep quick-start examples runnable.
-- Update cross-references when moving or renaming files.
-- For review handoffs, capture what remains to be done instead of transfusing raw
-  planning logs.
-
-If you notice obsolete or inaccurate docs, fix them in the same change rather
-than layering new “note” files.
-
-## Pull Request Checklist
-
-- [ ] Tests and builds succeed on your platform (note the preset/command used).
-- [ ] New code is formatted (`clang-format`) and clean (`clang-tidy`).
-- [ ] Documentation and comments reflect current behaviour.
-- [ ] Breaking changes are mentioned in the PR and, if relevant, `docs/public/reference/changelog.md`.
-- [ ] Any new assets or scripts are referenced in the repo’s structure guides.
-
-Respect these guidelines and we can keep the codebase approachable, accurate,
-and ready for the next set of contributors.

-## User Profile
+## Critical Rules
 
-- **User**: A Google programmer working on ROM hacking projects on macOS.
+1. **Use `build_ai/` directory** - Never use `build/` (reserved for user)
-- **IDE**: Visual Studio Code with the CMake Tools extension.
+2. **Use `*-ai` presets** - Never use `*-dbg` presets
-- **Build System**: CMake with a preference for the "Unix Makefiles" generator.
+3. **Load persona** - Check `.claude/agents/<agent-id>.md` for system prompt
-- **Workflow**: Uses CMake presets and a separate `build_test` directory for test builds.
+4. **Use helper script:**
-- **AI Assistant Build Policy**: When the AI assistant needs to build the project, it must use a dedicated build directory (e.g., `build_ai` or `build_agent`) to avoid interrupting the user's active builds. Never use `build` or `build_test` directories.
+   ```bash
+   ./scripts/agent_build.sh [target]
+   ```
+   *Example:* `./scripts/agent_build.sh yaze` or `./scripts/agent_build.sh yaze_test`
 
-## Project Overview
+---
 
-- **`yaze`**: A cross-platform GUI editor for "The Legend of Zelda: A Link to the Past" (ALTTP) ROMs. It is designed for compatibility with ZScream projects.
+## Quick Reference: Build Times
-- **`z3ed`**: A powerful command-line interface (CLI) for `yaze`. It features a resource-oriented design (`z3ed <resource> <action>`) and serves as the primary API for an AI-driven conversational agent.
-- **`yaze.org`**: The file `docs/yaze.org` is an Emacs Org-Mode file used as a development tracker for active issues and features.
 
-## Build Instructions
+**First Build (Cold Start)**:
+- **Fast Mode (Recommended)**: 2-4 minutes (uses system gRPC/sccache)
+- Standard Mode: 10-20 minutes (compiles gRPC from source)
 
-- Use the presets in `CMakePresets.json` (debug, AI, release, dev, CI, etc.). Always run the verifier
+**Incremental Builds (After Changes)**:
-  script before the first build on a machine.
+- Typically 10-60 seconds depending on what changed
-- Gemini agents must configure/build in dedicated directories (`build_ai`, `build_agent`, …) to avoid
+- **sccache/ccache**: Automatically detected and used if installed (highly recommended)
-  touching the user’s `build` or `build_test` folders.
+
-- Consult [`docs/public/build/quick-reference.md`](docs/public/build/quick-reference.md) for the
+## Platform-Specific Build Commands

 ## Testing
 
-- **Framework**: GoogleTest.
+### Running All Tests
-- **Test Categories**:
+
-    - `STABLE`: Fast, reliable, run in CI.
-    - `ROM_DEPENDENT`: Require a ROM file, skipped in CI unless a ROM is provided.
-    - `EXPERIMENTAL`: May be unstable, allowed to fail.
-- **Running Tests**:
 ```bash
-  # Run stable tests using ctest and presets
+# Build tests first
-  ctest --preset dev
+cmake --build build_ai --target yaze_test
 
-  # Run comprehensive overworld tests (requires a ROM)
+# Run all tests
-  ./scripts/run_overworld_tests.sh /path/to/zelda3.sfc
+./build_ai/bin/yaze_test
 ```
-- **E2E GUI Testing**: The project includes a sophisticated end-to-end testing framework using `ImGuiTestEngine`, accessible via a gRPC service. The `z3ed agent test` command can execute natural language prompts as GUI tests.
 
-## Core Architecture & Features
+### Running Specific Test Categories
 
-- **Overworld Editor**: Full support for vanilla and `ZSCustomOverworld` v2/v3 ROMs, ensuring compatibility with ZScream projects.
+```bash
-- **Dungeon Editor**: A modular, component-based system for editing rooms, objects, sprites, and more. See `docs/E2-dungeon-editor-guide.md` and `docs/E3-dungeon-editor-design.md`.
+# Unit tests only (fast, ~5-10 seconds)
-- **Graphics System**: A performant system featuring:
+./build/bin/yaze_test --unit
-    - `Arena`-based resource management.
-    - `Bitmap` class for SNES-specific graphics formats.
-    - `Tilemap` with an LRU cache.
-    - `AtlasRenderer` for batched drawing.
-- **Asar Integration**: Built-in support for the Asar 65816 assembler to apply assembly patches to the ROM.
 
-## Editor System Architecture
+# Integration tests (requires ROM file)
+./build/bin/yaze_test --integration --rom-path /path/to/zelda3.sfc
 
-The editor system is designed around a central `EditorManager` that orchestrates multiple editors and UI components.
+# End-to-end GUI tests
+./build/bin/yaze_test --e2e --show-gui
 
-- **`EditorManager`**: The top-level class that manages multiple `RomSession`s, the main menu, and all editor windows. It handles the application's main update loop.
+# Run specific test by name pattern
-- **`RomSession`**: Each session encapsulates a `Rom` instance and a corresponding `EditorSet`, allowing multiple ROMs to be open simultaneously.
+./build/bin/yaze_test "*Asar*"          # All tests with "Asar" in name
-- **`EditorSet`**: A container for all individual editor instances (Overworld, Dungeon, etc.) associated with a single ROM session.
+./build/bin/yaze_test "*Dungeon*"       # All dungeon-related tests
-- **`Editor` (Base Class)**: A virtual base class (`src/app/editor/editor.h`) that defines a common interface for all editors, including methods like `Initialize`, `Load`, `Update`, and `Save`.
+```
 
-### Component-Based Editors
+### Test Output Modes
-The project is moving towards a component-based architecture to improve modularity and maintainability. This is most evident in the Dungeon Editor.
 
-- **Dungeon Editor**: Refactored into a collection of single-responsibility components orchestrated by `DungeonEditor`:
+```bash
-    - `DungeonRoomSelector`: Manages the UI for selecting rooms and entrances.
+# Minimal output (default)
-    - `DungeonCanvasViewer`: Handles the rendering of the dungeon room on the main canvas.
+./build/bin/yaze_test
-    - `DungeonObjectSelector`: Provides the UI for browsing and selecting objects, sprites, and other editable elements.
-    - `DungeonObjectInteraction`: Manages mouse input, selection, and drag-and-drop on the canvas.
-    - `DungeonToolset`: The main toolbar for the editor.
-    - `DungeonRenderer`: A dedicated rendering engine for dungeon objects, featuring a cache for performance.
-    - `DungeonRoomLoader`: Handles the logic for loading all room data from the ROM, now optimized with parallel processing.
-    - `DungeonUsageTracker`: Analyzes and displays statistics on resource usage (blocksets, palettes, etc.).
 
-- **Overworld Editor**: Also employs a component-based approach with helpers like `OverworldEditorManager` for ZSCustomOverworld v3 features and `MapPropertiesSystem` for UI panels.
+# Verbose output (shows all test names)
+./build/bin/yaze_test -v
 
-### Specialized Editors
+# Very verbose (shows detailed test execution)
-- **Code Editors**: `AssemblyEditor` (a full-featured text editor) and `MemoryEditor` (a hex viewer).
+./build/bin/yaze_test -vv
-- **Graphics Editors**: `GraphicsEditor`, `PaletteEditor`, `GfxGroupEditor`, `ScreenEditor`, and the highly detailed `Tile16Editor` provide tools for all visual assets.
-- **Content Editors**: `SpriteEditor`, `MessageEditor`, and `MusicEditor` manage specific game content.
 
-### System Components
+# List all available tests without running
-Located in `src/app/editor/system/`, these components provide the core application framework:
+./build/bin/yaze_test --list-tests
-- `SettingsEditor`: Manages global and project-specific feature flags.
+```
-- `PopupManager`, `ToastManager`: Handle all UI dialogs and notifications.
-- `ShortcutManager`, `CommandManager`: Manage keyboard shortcuts and command palette functionality.
-- `ProposalDrawer`, `AgentChatWidget`: Key UI components for the AI Agent Workflow, allowing for proposal review and conversational interaction.
 
-## Game Data Models (`zelda3` Namespace)
+## Common Build Issues and Solutions
 
-The logic and data structures for ALTTP are primarily located in `src/zelda3/`.
+### Issue 1: "No preset found"
 
-- **`Rom` Class (`app/rom.h`)**: This is the most critical data class. It holds the entire ROM content in a `std::vector<uint8_t>` and provides the central API for all data access.
+**Error**: `CMake Error: No such preset in CMakePresets.json`
-    - **Responsibilities**: Handles loading/saving ROM files, stripping SMC headers, and providing low-level read/write primitives (e.g., `ReadByte`, `WriteWord`).
-    - **Game-Specific Loading**: The `LoadZelda3` method populates game-specific data structures like palettes (`palette_groups_`) and graphics groups.
-    - **State**: Manages a `dirty_` flag to track unsaved changes.
 
-- **Overworld Model (`zelda3/overworld/`)**:
+**Solution**: Check the exact preset name. Use tab-completion or check `CMakePresets.json`.
-    - `Overworld`: The main container class that orchestrates the loading of all overworld data, including maps, tiles, and entities. It correctly handles logic for both vanilla and `ZSCustomOverworld` ROMs.
-    - `OverworldMap`: Represents a single overworld screen, loading its own properties (palettes, graphics, music) based on the ROM version.
-    - `GameEntity`: A base class in `zelda3/common.h` for all interactive overworld elements like `OverworldEntrance`, `OverworldExit`, `OverworldItem`, and `Sprite`.
 
-- **Dungeon Model (`zelda3/dungeon/`)**:
+```bash
-    - `DungeonEditorSystem`: A high-level API that serves as the backend for the UI, managing all dungeon editing logic (adding/removing sprites, items, doors, etc.).
+# List available presets
-    - `Room`: Represents a single dungeon room, containing its objects, sprites, layout, and header information.
+cmake --list-presets
-    - `RoomObject` & `RoomLayout`: Define the structural elements of a room.
-    - `ObjectParser` & `ObjectRenderer`: High-performance components for directly parsing object data from the ROM and rendering them, avoiding the need for full SNES emulation.
 
-- **Sprite Model (`zelda3/sprite/`)**:
+# Common mistake: Using wrong platform prefix
-    - `Sprite`: Represents an individual sprite (enemy, NPC).
+cmake --preset dbg          # ❌ WRONG
-    - `SpriteBuilder`: A fluent API for programmatically constructing custom sprites.
+cmake --preset mac-dbg      # ✅ CORRECT (macOS)
-    - `zsprite.h`: Data structures for compatibility with Zarby's ZSpriteMaker format.
+cmake --preset lin-dbg      # ✅ CORRECT (Linux)
+cmake --preset win-dbg      # ✅ CORRECT (Windows)
+```
 
-- **Other Data Models**:
+### Issue 2: "Build directory exists but is outdated"
-    - `MessageData` (`message/`): Handles the game's text and dialogue system.
-    - `Inventory`, `TitleScreen`, `DungeonMap` (`screen/`): Represent specific non-gameplay screens.
-    - `music::Tracker` (`music/`): Contains legacy code from Hyrule Magic for handling SNES music data.
 
-## Graphics System (`gfx` Namespace)
+**Error**: CMake complains about existing build directory
 
-The `gfx` namespace contains a highly optimized graphics engine tailored for SNES ROM hacking.
+**Solution**: Clean and reconfigure
 
-- **Core Concepts**:
+```bash
-    - **`Bitmap`**: The fundamental class for image data. It supports SNES pixel formats, palette management, and is optimized with features like dirty-region tracking and a hash-map-based palette lookup cache for O(1) performance.
+# Remove old build directory
-    - **SNES Formats**: `snes_color`, `snes_palette`, and `snes_tile` provide structures and conversion functions for handling SNES-specific data (15-bit color, 4BPP/8BPP tiles, etc.).
+rm -rf build
-    - **`Tilemap`**: Represents a collection of tiles, using a texture `atlas` and a `TileCache` (with LRU eviction) for efficient rendering.
 
-- **Resource Management & Performance**:
+# Reconfigure from scratch
-    - **`Arena`**: A singleton that manages all graphics resources. It pools `SDL_Texture` and `SDL_Surface` objects to reduce allocation overhead and uses custom deleters for automatic cleanup. It also manages the 223 global graphics sheets for the game.
+cmake --preset mac-dbg  # or lin-dbg / win-dbg
-    - **`MemoryPool`**: A low-level, high-performance memory allocator that provides pre-allocated blocks for common graphics sizes, reducing `malloc` overhead and memory fragmentation.
+```
-    - **`AtlasRenderer`**: A key performance component that batches draw calls by combining multiple smaller graphics onto a single large texture atlas.
-    - **Batching**: The `Arena` supports batching texture updates via `QueueTextureUpdate`, which minimizes expensive, blocking calls to the SDL rendering API.
 
-- **Format Handling & Optimization**:
+### Issue 3: "Tests fail with 'ROM not found'"
-    - **`compression.h`**: Contains SNES-specific compression algorithms (LC-LZ2, Hyrule Magic) for handling graphics data from the ROM.
-    - **`BppFormatManager`**: A system for analyzing and converting between different bits-per-pixel (BPP) formats.
-    - **`GraphicsOptimizer`**: A high-level tool that uses the `BppFormatManager` to analyze graphics sheets and recommend memory and performance optimizations.
-    - **`scad_format.h`**: Provides compatibility with legacy Nintendo CAD file formats (CGX, SCR, COL) from the "gigaleak".
 
-- **Performance Monitoring**:
+**Error**: Integration tests fail with ROM-related errors
-    - **`PerformanceProfiler`**: A comprehensive system for timing operations using a `ScopedTimer` RAII class.
-    - **`PerformanceDashboard`**: An ImGui-based UI for visualizing real-time performance metrics collected by the profiler.
 
-## GUI System (`gui` Namespace)
+**Solution**: Some tests require a Zelda3 ROM file
 
-The `yaze` user interface is built with **ImGui** and is located in `src/app/gui`. It features a modern, component-based architecture designed for modularity, performance, and testability.
+```bash
+# Skip ROM-dependent tests
+./build/bin/yaze_test --unit
 
-### Canvas System (`gui::Canvas`)
+# Or provide ROM path
-The canvas is the core of all visual editors. The main `Canvas` class (`src/app/gui/canvas.h`) has been refactored from a monolithic class into a coordinator that leverages a set of single-responsibility components found in `src/app/gui/canvas/`.
+./build/bin/yaze_test --integration --rom-path zelda3.sfc
+```
 
-- **`Canvas`**: The main canvas widget. It provides a modern, ImGui-style interface (`Begin`/`End`) and coordinates the various sub-components for drawing, interaction, and configuration.
+### Issue 4: Long build times on first run
-- **`CanvasInteractionHandler`**: Manages all direct user input on the canvas, such as mouse clicks, drags, and selections for tile painting and object manipulation.
-- **`CanvasContextMenu`**: A powerful, data-driven context menu system. It is aware of the current `CanvasUsage` mode (e.g., `TilePainting`, `PaletteEditing`) and displays relevant menu items dynamically.
-- **`CanvasModals`**: Handles all modal dialogs related to the canvas, such as "Advanced Properties," "Scaling Controls," and "BPP Conversion," ensuring a consistent UX.
-- **`CanvasUsageTracker` & `CanvasPerformanceIntegration`**: These components provide deep analytics and performance monitoring. They track user interactions, operation timings, and memory usage, integrating with the global `PerformanceDashboard` to identify bottlenecks.
-- **`CanvasUtils`**: A collection of stateless helper functions for common canvas tasks like grid drawing, coordinate alignment, and size calculations, promoting code reuse.
 
-### Theming and Styling
+**Not an Error**: This is normal!
-The visual appearance of the editor is highly customizable through a robust theming system.
 
-- **`ThemeManager`**: A singleton that manages `EnhancedTheme` objects. It can load custom themes from `.theme` files, allowing users to personalize the editor's look and feel. It includes a built-in theme editor and selector UI.
+**Explanation**:
-- **`BackgroundRenderer`**: Renders the animated, futuristic grid background for the main docking space, providing a polished, modern aesthetic.
+- CPM.cmake downloads all dependencies (~3-5 minutes)
-- **`style.cc` & `color.cc`**: Contain custom ImGui styling functions (`ColorsYaze`), `SnesColor` conversion utilities, and other helpers to maintain a consistent visual identity.
+- gRPC compilation (Windows only, ~15-20 minutes)
+- ImGui compilation (~2-3 minutes)
+- SDL2, Abseil, PNG libraries (~3-5 minutes)
 
-### Specialized UI Components
+**Solution**: Be patient on first build. Subsequent builds use ccache/sccache and are MUCH faster (10-60 seconds).
-The `gui` namespace includes several powerful, self-contained widgets for specific ROM hacking tasks.
 
-- **`BppFormatUI`**: A comprehensive UI for managing SNES bits-per-pixel (BPP) graphics formats. It provides a format selector, a detailed analysis panel, a side-by-side conversion preview, and a batch comparison tool.
+```bash
-- **`EnhancedPaletteEditor`**: An advanced tool for editing `SnesPalette` objects. It features a grid-based editor, a ROM palette manager for loading palettes directly from the game, and a color analysis view to inspect pixel distribution.
+# Monitor build progress with verbose output
-- **`TextEditor`**: A full-featured text editor widget with syntax highlighting for 65816 assembly, undo/redo functionality, and standard text manipulation features.
+cmake --build build --preset mac-dbg -v | tee build.log
-- **`AssetBrowser`**: A flexible, icon-based browser for viewing and managing game assets, such as graphics sheets.
 
-### Widget Registry for Automation
+# Check build log for specific step taking long
-A key feature for test automation and AI agent integration is the discoverability of UI elements.
+grep "Linking" build.log
+```
 
-- **`WidgetIdRegistry`**: A singleton that catalogs all registered GUI widgets. It assigns a stable, hierarchical path (e.g., `Overworld/Canvas/Map`) to each widget, making the UI programmatically discoverable. This is the backbone of the `z3ed agent test` command.
+### Issue 5: Incremental builds seem slow
-- **`WidgetIdScope`**: An RAII helper that simplifies the creation of hierarchical widget IDs by managing an ID stack, ensuring that widget paths are consistent and predictable.
 
-## ROM Hacking Context
+**Solution**: Only rebuild what changed
 
-- **Game**: The Legend of Zelda: A Link to the Past (US/JP).
+```bash
-- **`ZSCustomOverworld`**: A popular system for expanding overworld editing capabilities. `yaze` is designed to be fully compatible with ZScream's implementation of v2 and v3.
+# Instead of rebuilding everything:
-- **Assembly**: Uses `asar` for 65816 assembly. A style guide is available at `docs/E1-asm-style-guide.md`.
+cmake --build build --preset mac-dbg              # ❌ Rebuilds all targets
-- **`usdasm` Disassembly**: The user has a local copy of the `usdasm` ALTTP disassembly at `/Users/scawful/Code/usdasm` which can be used for reference.
 
-## Git Workflow
+# Build only what you need:
+cmake --build build --target yaze                 # ✅ Just the GUI app
+cmake --build build --target ylib                 # ✅ Just the core library
+cmake --build build --target object_editor_card   # ✅ Just one component
+```
 
-The project follows a simplified Git workflow for pre-1.0 development, with a more formal process documented for the future. For details, see `docs/B4-git-workflow.md`.
+## Development Workflow
 
-- **Current (Pre-1.0)**: A relaxed model is in use. Direct commits to `develop` or `master` are acceptable for documentation and small fixes. Feature branches are used for larger, potentially breaking changes.
+### Typical Development Session
-- **Future (Post-1.0)**: The project will adopt a formal Git Flow model with `master`, `develop`, feature, release, and hotfix branches.
 
-## AI Agent Workflow (`z3ed agent`)
+```bash
+# 1. Configure once (first time only)
+cmake --preset mac-dbg
 
-A primary focus of the `yaze` project is its AI-driven agentic workflow, orchestrated by the `z3ed` CLI.
+# 2. Make code changes to src/app/editor/dungeon/object_editor_card.cc
 
-- **Vision**: To create a conversational ROM hacking assistant that can inspect the ROM and perform edits based on natural language.
+# 3. Rebuild only the affected target (fast!)
-- **Core Loop (MCP)**:
+cmake --build build --target yaze
-    1.  **Model (Plan)**: The user provides a prompt. The agent uses an LLM (Ollama or Gemini) to create a plan, which is a sequence of `z3ed` commands.
+
-    2.  **Code (Generate)**: The LLM generates the commands based on a machine-readable catalog of the CLI's capabilities.
+# 4. Run the application to test manually
-    3.  **Program (Execute)**: The `z3ed` agent executes the commands.
+./build/bin/yaze --rom_file zelda3.sfc --editor Dungeon
-- **Proposal System**: To ensure safety, agent-driven changes are not applied directly. They are executed in a **sandboxed ROM copy** and saved as a **proposal**.
+
-- **Review & Acceptance**: The user can review the proposed changes via `z3ed agent diff` or a dedicated `ProposalDrawer` in the `yaze` GUI. The user must explicitly **accept** a proposal to merge the changes into the main ROM.
+# 5. Run automated tests to verify
-- **Tool Use**: The agent can use read-only `z3ed` commands (e.g., `overworld-find-tile`, `dungeon-list-sprites`) as "tools" to inspect the ROM and gather context to answer questions or formulate a plan.
+./build/bin/yaze_test --unit
-- **API Discovery**: The agent learns the available commands and their schemas by calling `z3ed agent describe`, which exports the entire CLI surface area in a machine-readable format.
+
-- **Function Schemas**: The Gemini AI service uses function calling schemas defined in `assets/agent/function_schemas.json`. These schemas are automatically copied to the build directory and loaded at runtime. To modify the available functions, edit this JSON file rather than hardcoding them in the C++ source.
+# 6. If tests pass, commit
+git add src/app/editor/dungeon/object_editor_card.cc
+git commit -m "feat(dungeon): add feature X"
+```
+
+### Testing Dungeon Editor Changes
+
+```bash
+# 1. Build just the GUI app (includes dungeon editor)
+cmake --build build --target yaze
+
+# 2. Launch directly to dungeon editor with ROM
+./build/bin/yaze --rom_file zelda3.sfc --editor Dungeon
+
+# 3. To test keyboard shortcuts specifically:
+#    - Open Object Editor card
+#    - Try Ctrl+A (select all)
+#    - Try Delete key (delete selected)
+#    - Try Ctrl+D (duplicate)
+#    - Try Arrow keys (nudge objects)
+#    - Try Tab (cycle selection)
+```
+
+### Before Committing Changes
+
+```bash
+# 1. Run unit tests (fast check)
+./build/bin/yaze_test --unit
+
+# 2. Run format check (ensure code style)
+cmake --build build --target format-check
+
+# 3. If format check fails, auto-format
+cmake --build build --target format
+
+# 4. Build in release mode to catch optimization warnings
+cmake --preset mac-rel
+cmake --build build --preset mac-rel
+
+# 5. If all passes, you're ready to commit!

+## Key Reminders
+
+- Use full preset names: `mac-ai` not just `ai`
+- First builds: 10-20 min (normal), incremental: 10-60 sec
+- Build specific targets: `--target yaze` faster than full build
+- Some tests require ROM file to pass

+A cross-platform Zelda 3 ROM editor with a modern C++ GUI, Asar 65816 assembler integration, and an automation-friendly CLI (`z3ed`). YAZE bundles its toolchain, offers AI-assisted editing flows, and targets reproducible builds on Windows, macOS, and Linux. A preview web version is also available for browser-based editing.
 
 ## Highlights
 - **All-in-one editing**: Overworld, dungeon, sprite, palette, and messaging tools with live previews.
 - **Assembler-first workflow**: Built-in Asar integration, symbol extraction, and patch validation.
 - **Automation & AI**: `z3ed` exposes CLI/TUI automation, proposal workflows, and optional AI agents.
+- **Web preview**: Experimental browser-based editor (WASM) - see [Web App Guide](docs/public/usage/web-app.md).
 - **Testing & CI hooks**: CMake presets, ROM-less test fixtures, and gRPC-based GUI automation support.
 - **Cross-platform toolchains**: Single source tree targeting MSVC, Clang, and GCC with identical presets.
 - **Modular AI stack**: Toggle agent UI (`YAZE_BUILD_AGENT_UI`), remote automation/gRPC (`YAZE_ENABLE_REMOTE_AUTOMATION`), and AI runtimes (`YAZE_ENABLE_AI_RUNTIME`) per preset.
 
 ## Project Status
-`0.3.x` builds are in active development. Release automation is being reworked, so packaged builds may lag behind main. Follow `develop` for the most accurate view of current functionality.
+v0.5.0 is the current release. New to YAZE? Start with a clean, legally obtained ALttP (USA) ROM and the Quick Start steps below. See [`docs/public/release-notes.md`](docs/public/release-notes.md) for details.
 
 ## Quick Start
 
@@ -57,27 +58,28 @@ All bundled third-party code (SDL, ImGui, ImGui Test Engine, Asar, nlohmann/json
 
 ## Applications & Workflows
 - **`./build/bin/yaze`** – full GUI editor with multi-session dockspace, theming, and ROM patching.
+- **Web App (Preview)** – browser-based editor at your deployed instance; see [`docs/public/usage/web-app.md`](docs/public/usage/web-app.md) for details and limitations.
 - **`./build/bin/z3ed --tui`** – CLI/TUI companion for scripting, AI-assisted edits, and Asar workflows.
-- **`./build_ai/bin/yaze_test --unit|--integration|--e2e`** – structured test runner for quick regression checks.
+- **`ctest --test-dir build -L unit|integration|e2e`** – structured test runner for quick regression checks.
 - **`z3ed` + macOS automation** – pair the CLI with sketchybar/yabai/skhd or Emacs/Spacemacs to drive ROM workflows without opening the GUI.
 
 Typical commands:
 ```bash
 # Launch GUI with a ROM
-./build/bin/yaze zelda3.sfc
+./build/bin/yaze roms/alttp_vanilla.sfc
 
 # Apply a patch via CLI
-./build/bin/z3ed asar patch.asm --rom zelda3.sfc
+./build/bin/z3ed asar patch.asm --rom roms/alttp_vanilla.sfc
 
 # Run focused tests
 cmake --build --preset mac-ai --target yaze_test
-./build_ai/bin/yaze_test --unit
+ctest --test-dir build -L unit
 ```
 
 ## Testing
-- `./build_ai/bin/yaze_test --unit` for fast checks; add `--integration` or `--e2e --show-gui` for broader coverage.
+- `ctest --test-dir build -L unit` for fast checks; add `-L integration` or `-L e2e --output-on-failure` for broader coverage.
 - `ctest --preset dev` mirrors CI’s stable set; `ctest --preset all` runs the full matrix.
-- Set `YAZE_TEST_ROM_PATH` or pass `--rom-path` when a test needs a real ROM image.
+- Set `YAZE_TEST_ROM_VANILLA` or pass `--rom-vanilla` when a test needs a real ROM image (legacy `--rom-path` still works).

+;Expands the overworld pointer tables from 160 to 192 entries,
+;enabling support for Special World tail maps (0xA0-0xBF).
+;
+;IMPORTANT: This patch MUST be applied AFTER ZSCustomOverworld v3.

+;
+;If applied via yaze CLI:
+;  z3ed overworld-doctor --rom=your_rom.sfc --apply-tail-expansion
+;
+;Technical details:
+;  - Relocates Map32 pointer tables from $02:F94D to $28:A400
+;  - Adds 32 blank entries for maps 0xA0-0xBF pointing to $30:8000

-# AI API & Agentic Workflow Enhancement - Handoff Document
-
-**Date**: 2025-01-XX  
-**Status**: Phase 1 Complete, Phase 2-4 Pending  
-**Branch**: (to be determined)
-
-## Executive Summary
-
-This document tracks progress on transforming Yaze into an AI-native platform with unified model management, API interface, and enhanced agentic workflows. Phase 1 (Unified Model Management) is complete. Phases 2-4 require implementation.
-
-## Completed Work (Phase 1)
-
-### 1. Unified AI Model Management ✅
-
-#### Core Infrastructure
-- **`ModelInfo` struct** (`src/cli/service/ai/common.h`)
-  - Standardized model representation across all providers
-  - Fields: `name`, `display_name`, `provider`, `description`, `family`, `parameter_size`, `quantization`, `size_bytes`, `is_local`
-  
-- **`ModelRegistry` class** (`src/cli/service/ai/model_registry.h/.cc`)
-  - Singleton pattern for managing multiple `AIService` instances
-  - `RegisterService()` - Add service instances
-  - `ListAllModels()` - Aggregate models from all registered services
-  - Thread-safe with mutex protection
-
-#### AIService Interface Updates
-- **`AIService::ListAvailableModels()`** - Virtual method returning `std::vector<ModelInfo>`
-- **`AIService::GetProviderName()`** - Virtual method returning provider identifier
-- Default implementations provided in base class
-
-#### Provider Implementations
-- **`OllamaAIService::ListAvailableModels()`**
-  - Queries `/api/tags` endpoint
-  - Maps Ollama's model structure to `ModelInfo`
-  - Handles size, quantization, family metadata
-  
-- **`GeminiAIService::ListAvailableModels()`**
-  - Queries Gemini API `/v1beta/models` endpoint
-  - Falls back to known defaults if API key missing
-  - Filters for `gemini*` models
-
-#### UI Integration
-- **`AgentChatWidget::RefreshModels()`**
-  - Registers Ollama and Gemini services with `ModelRegistry`
-  - Aggregates models from all providers
-  - Caches results in `model_info_cache_`
-  
-- **Header updates** (`agent_chat_widget.h`)
-  - Replaced `ollama_model_info_cache_` with unified `model_info_cache_`
-  - Replaced `ollama_model_cache_` with `model_name_cache_`
-  - Replaced `ollama_models_loading_` with `models_loading_`
-
-### Files Modified
-- `src/cli/service/ai/common.h` - Added `ModelInfo` struct
-- `src/cli/service/ai/ai_service.h` - Added `ListAvailableModels()` and `GetProviderName()`
-- `src/cli/service/ai/ollama_ai_service.h/.cc` - Implemented model listing
-- `src/cli/service/ai/gemini_ai_service.h/.cc` - Implemented model listing
-- `src/cli/service/ai/model_registry.h/.cc` - New registry class
-- `src/app/editor/agent/agent_chat_widget.h/.cc` - Updated to use registry
-
-## In Progress
-
-### UI Rendering Updates (Partial)
-The `RenderModelConfigControls()` function in `agent_chat_widget.cc` still references old Ollama-specific code. It needs to be updated to:
-- Use unified `model_info_cache_` instead of `ollama_model_info_cache_`
-- Display models from all providers in a single list
-- Filter by provider when a specific provider is selected
-- Show provider badges/indicators for each model
-
-**Location**: `src/app/editor/agent/agent_chat_widget.cc:2083-2318`
-
-**Current State**: Function still has provider-specific branches that should be unified.
-
-## Remaining Work
-
-### Phase 2: API Interface & Headless Mode
-
-#### 2.1 HTTP Server Implementation
-**Goal**: Expose Yaze functionality via REST API for external agents
-
-**Tasks**:
-1. Create `HttpServer` class in `src/cli/service/api/`
-   - Use `httplib` (already in tree)
-   - Start on configurable port (default 8080)
-   - Handle CORS if needed
-   
-2. Implement endpoints:
-   - `GET /api/v1/models` - List all available models (delegate to `ModelRegistry`)
-   - `POST /api/v1/chat` - Send prompt to agent
-     - Request: `{ "prompt": "...", "provider": "ollama", "model": "...", "history": [...] }`
-     - Response: `{ "text_response": "...", "tool_calls": [...], "commands": [...] }`
-   - `POST /api/v1/tool/{tool_name}` - Execute specific tool
-     - Request: `{ "args": {...} }`
-     - Response: `{ "result": "...", "status": "ok|error" }`
-   - `GET /api/v1/health` - Health check
-   - `GET /api/v1/rom/status` - ROM loading status
-
-3. Integration points:
-   - Initialize server in `yaze.cc` main() or via CLI flag
-   - Share `Rom*` context with API handlers
-   - Use `ConversationalAgentService` for chat endpoint
-   - Use `ToolDispatcher` for tool endpoint
-
-**Files to Create**:
-- `src/cli/service/api/http_server.h`
-- `src/cli/service/api/http_server.cc`
-- `src/cli/service/api/api_handlers.h`
-- `src/cli/service/api/api_handlers.cc`
-
-**Dependencies**: `httplib`, `nlohmann/json` (already available)
-
-### Phase 3: Enhanced Agentic Workflows
-
-#### 3.1 Tool Expansion
-
-**FileSystemTool** (`src/cli/handlers/tools/filesystem_commands.h/.cc`)
-- **Purpose**: Allow agent to read/write files outside ROM (e.g., `src/` directory)
-- **Safety**: Require user confirmation or explicit scope configuration
-- **Commands**:
-  - `filesystem-read <path>` - Read file contents
-  - `filesystem-write <path> <content>` - Write file (with confirmation)
-  - `filesystem-list <directory>` - List directory contents
-  - `filesystem-search <pattern>` - Search for files matching pattern
-
-**BuildTool** (`src/cli/handlers/tools/build_commands.h/.cc`)
-- **Purpose**: Trigger builds from within agent
-- **Commands**:
-  - `build-cmake <build_dir>` - Run cmake configuration
-  - `build-ninja <build_dir>` - Run ninja build
-  - `build-status` - Check build status
-  - `build-errors` - Parse and return compilation errors
-
-**Integration**:
-- Add to `ToolDispatcher::ToolCallType` enum
-- Register in `ToolDispatcher::CreateHandler()`
-- Add to `ToolDispatcher::ToolPreferences` struct
-- Update UI toggles in `AgentChatWidget::RenderToolingControls()`
-
-#### 3.2 Editor State Context
-**Goal**: Feed editor state (open files, compilation errors) into agent context
-
-**Tasks**:
-1. Create `EditorState` struct capturing:
-   - Open file paths
-   - Active editor type
-   - Compilation errors (if any)
-   - Recent changes
-
-2. Inject into agent prompts:
-   - Add to `PromptBuilder::BuildPromptFromHistory()`
-   - Include in system prompt when editor state changes
-
-3. Update `ConversationalAgentService`:
-   - Add `SetEditorState(EditorState*)` method
-   - Pass to `PromptBuilder` when building prompts
-
-**Files to Create/Modify**:
-- `src/cli/service/agent/editor_state.h` (new)
-- `src/cli/service/ai/prompt_builder.h/.cc` (modify)
-
-### Phase 4: Refactoring
-
-#### 4.1 ToolDispatcher Structured Output
-**Goal**: Return JSON instead of capturing stdout
-
-**Current State**: `ToolDispatcher::Dispatch()` returns `absl::StatusOr<std::string>` by capturing stdout from command handlers.
-
-**Proposed Changes**:
-1. Create `ToolResult` struct:
-   ```cpp
-   struct ToolResult {
-     std::string output;  // Human-readable output
-     nlohmann::json data;  // Structured data (if applicable)
-     bool success;
-     std::vector<std::string> warnings;
-   };
-   ```
-
-2. Update command handlers to return `ToolResult`:
-   - Modify base `CommandHandler` interface
-   - Update each handler implementation
-   - Keep backward compatibility with `OutputFormatter` for CLI
-
-3. Update `ToolDispatcher::Dispatch()`:
-   - Return `absl::StatusOr<ToolResult>`
-   - Convert to JSON for API responses
-   - Keep string output for CLI compatibility
-
-**Files to Modify**:
-- `src/cli/service/agent/tool_dispatcher.h/.cc`
-- `src/cli/handlers/*/command_handlers.h/.cc` (all handlers)
-- `src/cli/service/agent/command_handler.h` (base interface)
-
-**Migration Strategy**:
-- Add new `ExecuteStructured()` method alongside existing `Execute()`
-- Gradually migrate handlers
-- Keep old path for CLI until migration complete
-
-## Technical Notes
-
-### Model Registry Usage Pattern
-```cpp
-// Register services
-auto& registry = cli::ModelRegistry::GetInstance();
-registry.RegisterService(std::make_shared<OllamaAIService>(ollama_config));
-registry.RegisterService(std::make_shared<GeminiAIService>(gemini_config));
-
-// List all models
-auto models_or = registry.ListAllModels();
-// Returns unified list sorted by name
-```
-
-### API Key Management
-- Gemini API key: Currently stored in `AgentConfigState::gemini_api_key`
-- Consider: Environment variable fallback, secure storage
-- Future: Support multiple API keys for different providers
-
-### Thread Safety
-- `ModelRegistry` uses mutex for thread-safe access
-- `HttpServer` should handle concurrent requests (httplib supports this)
-- `ToolDispatcher` may need locking if shared across threads
-
-## Testing Checklist
-
-### Phase 1 (Model Management)
-- [ ] Verify Ollama models appear in unified list
-- [ ] Verify Gemini models appear in unified list
-- [ ] Test model refresh with multiple providers
-- [ ] Test provider filtering in UI
-- [ ] Test model selection and configuration
-
-### Phase 2 (API)
-- [ ] Test `/api/v1/models` endpoint
-- [ ] Test `/api/v1/chat` with different providers
-- [ ] Test `/api/v1/tool/*` endpoints
-- [ ] Test error handling (missing ROM, invalid tool, etc.)
-- [ ] Test concurrent requests
-- [ ] Test CORS if needed
-
-### Phase 3 (Tools)
-- [ ] Test FileSystemTool with read operations
-- [ ] Test FileSystemTool write confirmation flow
-- [ ] Test BuildTool cmake/ninja execution
-- [ ] Test BuildTool error parsing
-- [ ] Test editor state injection into prompts
-
-### Phase 4 (Refactoring)
-- [ ] Verify all handlers return structured output
-- [ ] Test API endpoints with new format
-- [ ] Verify CLI still works with old format
-- [ ] Performance test (no regressions)
-
-## Known Issues
-
-1. **UI Rendering**: `RenderModelConfigControls()` still has provider-specific code that should be unified
-2. **Model Info Display**: Some fields from `ModelInfo` (like `quantization`, `modified_at`) are not displayed in unified view
-3. **Error Handling**: Model listing failures are logged but don't prevent other providers from loading
-
-## Next Steps (Priority Order)
-
-1. **Complete UI unification** - Update `RenderModelConfigControls()` to use unified model list
-2. **Implement HTTP Server** - Start with basic server and `/api/v1/models` endpoint
-3. **Add chat endpoint** - Wire up `ConversationalAgentService` to API
-4. **Add tool endpoint** - Expose `ToolDispatcher` via API
-5. **Implement FileSystemTool** - Start with read-only operations
-6. **Implement BuildTool** - Basic cmake/ninja execution
-7. **Refactor ToolDispatcher** - Begin structured output migration

-
-## Questions for Next Developer
-
-1. Should the HTTP server be enabled by default or require a flag?
-2. What port should be used? (8080 suggested, but configurable?)
-3. Should FileSystemTool require explicit user approval per operation or a "trusted scope"?
-4. Should BuildTool be limited to specific directories (e.g., `build/`) for safety?
-5. How should API authentication work? (API key? Localhost-only? None?)

+# Agent Coordination Hub
+
+Welcome to the `yaze` internal agent workspace. This directory contains the rules, roles, and records for AI agents contributing to the project.
+
+## Quick Start
+1.  **Identify Your Role**: Check [personas.md](./personas.md) to choose the correct Agent ID.
+2.  **Load Your Prompt**: Open `.claude/agents/<agent-id>.md` for your persona’s system prompt (available to all agents).
+3.  **Follow the Protocol**: Read [AGENTS.md](../../../AGENTS.md) for rules on communication, task logging, and handoffs.
+4.  **Check Status**: Review the [coordination-board.md](./coordination-board.md) for active tasks and blockers.
+5.  **Keep docs lean**: Use [doc-hygiene.md](./doc-hygiene.md) and avoid creating duplicate specs; archive idle docs.
+
+## Documentation Index
+
+### Core Coordination (Keep Visible)
+| File | Purpose |
+|------|---------|
+| [AGENTS.md](../../../AGENTS.md) | **The Core Protocol.** Read this first. Defines how to work. |
+| [personas.md](./personas.md) | **Who is Who.** Canonical list of Agent IDs and their scopes. |
+| [.claude/agents/*](../../../.claude/agents) | **System Prompts.** Persona-specific prompts for all agents. |
+| [coordination-board.md](./coordination-board.md) | **The Live Board.** Shared state, active tasks, and requests. |
+| [collaboration-framework.md](./collaboration-framework.md) | **Team Organization.** Architecture vs Automation team structure and protocols. |

+| File | Purpose |
+|------|---------|
+| [doc-hygiene.md](./doc-hygiene.md) | Rules to keep specs/notes lean and archived on time. |
+
+## Tools
+Agents have built-in CLI capabilities to assist with this workflow:
+*   `z3ed agent todo`: Manage your personal task list.
+*   `z3ed agent handoff`: Generate context bundles for the next agent.
+*   `z3ed agent chat`: (If enabled) Inter-agent communication channel.
+
+## Picking the right agent
+- **ai-infra-architect**: AI/agent infra, MCP/gRPC, z3ed tooling, model plumbing.
+- **backend-infra-engineer**: Build/packaging/toolchains, CI reliability, release plumbing.
+- **imgui-frontend-engineer**: ImGui/editor UI, renderer/backends, canvas/docking UX.
+- **snes-emulator-expert**: Emulator core (CPU/APU/PPU), performance/accuracy/debugging.
+- **zelda3-hacking-expert**: Gameplay/ROM logic, data formats, hacking workflows.
+- **test-infrastructure-expert**: Test harnesses, CTest/gMock infra, flake/bloat triage.
+- **docs-janitor**: Docs/process hygiene, onboarding, checklists.
+Pick the persona that owns the dominant surface of your task; cross-surface work should add both owners to the board entry.
+
+## Build & Test
+Default builds now share `build/` (native) and `build-wasm/` (WASM). If you need isolation, set `YAZE_BUILD_DIR` or create a local `CMakeUserPresets.json`.
+*   **Build**: `./scripts/agent_build.sh [target]` (Default target: `yaze`)
+*   **Test**: `./scripts/agent_build.sh yaze_test && ./build/bin/yaze_test`
+*   **Directory**: `build/` by default (override via `YAZE_BUILD_DIR`).

+## Removed Directories
+
+- ❌ `docs/web/` - consolidated into internal
+- ❌ `docs/wasm/` - consolidated into internal
+
+## Documentation Principles Applied
+
+1. **Public vs Internal Separation**
+   - Public: User-facing, stable, external developers
+   - Internal: AI agents, implementation details, planning
+
+2. **Accuracy & Honesty**
+   - Web app clearly marked as preview/experimental
+   - Editor status accurately reflects incomplete state
+   - Recommended desktop for production work
+
+3. **Organization**
+   - Format docs in reference section for easy discovery
+   - Technical implementation in internal for developers
+   - Clear navigation through index files
+
+4. **Currency**
+   - Updated "Last Modified" dates
+   - Removed outdated content
+   - Consolidated duplicate information
+
+## Impact
+
+### For Users

+# Draw Routine Fixes - Phase 2
+
+## Status
+**Owner:** ai-dungeon-specialist  
+**Created:** 2025-12-07  
+**Status:** Partial Complete - Build Verified
+
+## Summary
+
+This document tracks fixes for specific dungeon object draw routines and outline sizing issues identified during testing. These issues complement the Phase 1 diagonal/edge/spacing fixes.
+
+## Issues to Fix
+
+### Issue 1: Block 0x5E Draw Routine Inverted
+**Object:** 0x5E (RoomDraw_RightwardsBlock2x2spaced2_1to16)  
+**Problem:** Draw routine is inverted for the simple block pattern  
+**ASM Reference:** bank_01.asm line 363  
+**Fix Required:** Review tile ordering and column-major vs row-major layout
+
+### Issue 2: Vertical Pegs Wrong Outline Shape
+**Objects:** 0x95 (DownwardsPots2x2), 0x96 (DownwardsHammerPegs2x2)  
+**Problem:** Selection outline shows 2x2 square but should be vertical single row (1 tile wide)  
+**ASM Reference:** RoomDraw_DownwardsPots2x2_1to16, RoomDraw_DownwardsHammerPegs2x2_1to16  
+**Analysis:** The pots/pegs are 2x2 objects that repeat vertically with 2-row spacing (0x100). However, user reports they should display as 1-tile-wide vertical strips. Need to verify actual drawn dimensions from ASM.  
+**Fix Required:** Update dimension calculations in CalculateObjectDimensions and ObjectDimensionTable
+
+### Issue 3: Thick Rail Horizontal/Vertical Draw Issues
+**Objects:** 0x5D (RightwardsBigRail1x3), 0x88 (DownwardsBigRail3x1)  
+**Problem:** Repeats far left edge rather than inner parts of the thick rail  
+**ASM Reference:** RoomDraw_RightwardsBigRail1x3_1to16plus5, RoomDraw_DownwardsBigRail3x1_1to16plus5  
+**Analysis:** ASM shows:
+- First draws a 2x2 block, then advances tile pointer by 8
+- Then draws middle section (1x3 tiles per iteration)
+- Finally draws end cap (2 tiles)
+**Fix Required:** Fix draw routine to draw: left cap → middle repeating → right cap
+
+### Issue 4: Large Decor Outline Too Small, Draw Routine Repeats Incorrectly
+**Problem:** Large decoration objects have outlines that are too small and draw routines that repeat when they shouldn't  
+**Fix Required:** Identify specific objects and verify repetition count logic (size+1 vs size)
+
+### Issue 5: Ceiling 0xC0 Doesn't Draw Properly
+**Object:** 0xC0 (RoomDraw_4x4BlocksIn4x4SuperSquare)  
+**Problem:** Object doesn't draw at all or draws incorrectly  
+**ASM Reference:** bank_01.asm lines 1779-1831  
+**Analysis:** Uses complex 4x4 super-square pattern with 8 buffer pointers ($BF through $D4). Draws 4x4 blocks in a grid pattern based on size parameters B2 and B4.  
+**Fix Required:** Implement proper super-square drawing routine
+
+### Issue 6: 0xF99 Chest Outline Correct But Draw Routine Repeats
+**Object:** 0xF99 (RoomDraw_Chest - Type 3 chest)  
+**Problem:** Outline is correct but draw routine repeats when it shouldn't  
+**ASM Reference:** RoomDraw_Chest at bank_01.asm line 4707  
+**Analysis:** Chest should only draw once (single 2x2 pattern), not repeat based on size  
+**Fix Required:** Remove size-based repetition from chest draw routine
+
+### Issue 7: Pit Edges Outlines Too Thin
+**Problem:** Pit edge outlines shouldn't be single tile thin based on direction  
+**Objects:** Various pit edge objects  
+**Fix Required:** Update pit edge dimension calculations to include proper width based on direction
+
+### Issue 8: 0x3D Tall Torches Wrong Top Half Graphics
+**Object:** 0x3D (mapped to RoomDraw_RightwardsPillar2x4spaced4_1to16)  
+**Problem:** Bottom half draws correctly but top half with fire draws pegs instead  
+**ASM Reference:** bank_01.asm line 330 - uses RoomDraw_RightwardsPillar2x4spaced4_1to16 (same as 0x39)  
+**Analysis:** Object 0x3D and 0x39 share the same draw routine but use different tile data. Need to verify tile data offset is correct.  
+**Fix Required:** Verify tile data loading for 0x3D or create dedicated draw routine
+
+## Implementation Status
+
+### Completed Fixes
+1. **Block 0x5E** ✅ - Fixed tile ordering in DrawRightwardsBlock2x2spaced2_1to16 to use column-major order
+2. **Thick Rails 0x5D/0x88** ✅ - Rewrote DrawRightwardsBigRail and DrawDownwardsBigRail to correctly draw cap-middle-cap pattern
+3. **Chest 0xF99** ✅ - Fixed chest to draw single 2x2 pattern without size-based repetition
+4. **Large Decor 0xFEB** ✅ - Created Single4x4 routine (routine 113) - no repetition, correct 32x32 outline
+5. **Water Grate 0xFED** ✅ - Created Single4x3 routine (routine 114) - no repetition, correct 32x24 outline
+6. **Big Chest 0xFB1** ✅ - Mapped to Single4x3 routine (routine 114) - no repetition
+7. **Blue Rupees 0xF92** ✅ - Created DrawRupeeFloor routine (routine 115) - special 6x8 pattern with gaps
+
+### Pending Investigation
+8. **Rails 0x022** - Uses RoomDraw_RightwardsHasEdge1x1_1to16_plus3 - needs internal rail drawing
+9. **Ceiling 0xC0** - Draw4x4BlocksIn4x4SuperSquare may have tile loading issue
+10. **Vertical Pegs 0x95/0x96** - Current dimensions look correct. May be UI display issue.
+11. **Pit Edges** - Need specific object IDs to investigate
+12. **Torches 0x3D** - May be ROM tile data issue (verify data at 0x807A)
+
+## New Routines Added
+- Routine 113: DrawSingle4x4 - Single 4x4 block, no repetition
+- Routine 114: DrawSingle4x3 - Single 4x3 block, no repetition  
+- Routine 115: DrawRupeeFloor - Special 6x8 pattern with gaps at rows 2 and 5

+# Draw Routine Fixes - Handoff Document
+
+**Status:** Handoff  
+**Owner:** draw-routine-engineer  
+**Created:** 2025-12-07  
+**Last Session:** 2025-12-07  
+
+---
+
+## Summary
+
+This session made significant progress on dungeon object draw routines. Many fixes were completed, but some objects still have minor issues requiring further investigation.
+
+---
+
+## Completed Fixes ✅
+
+| Object ID | Name | Fix Applied |
+|-----------|------|-------------|
+| 0x5E | Block | Fixed column-major tile ordering |
+| 0x5D/0x88 | Thick Rails | Fixed cap-middle-cap pattern |
+| 0xF99 | Chest | Changed to DrawSingle2x2 (no size-based repeat) |
+| 0xFB1 | Big Chest | Changed to DrawSingle4x3 (no repeat) |
+| 0xF92 | Blue Rupees | Implemented DrawRupeeFloor per ASM (3x8 pattern) |
+| 0xFED | Water Grate | Changed to DrawSingle4x3 (no repeat) |
+| 0x3A | Wall Decors | Fixed spacing from 6 to 8 tiles |
+| 0x39/0x3D | Pillars | Fixed spacing from 6 to 4 tiles |
+| 0xFEB | Large Decor | Now 64x64 (4x4 tile16s = 8x8 tile8s) |
+| 0x138-0x13B | Spiral Stairs | Fixed to 4x3 pattern per ASM |
+| 0xC0/0xC2 | SuperSquare Ceilings | Dimensions now use size parameter |
+| 0xFE6 | Pit | Uses DrawActual4x4 (32x32, no repeat) |
+| 0x55-0x56 | Wall Torches | Fixed to 1x8 column with 12-tile spacing |
+| 0x22 | Small Rails | Now CORNER+MIDDLE*count+END pattern |
+| 0x23-0x2E | Carpet Trim | Now CORNER+MIDDLE*count+END pattern |
+
+---
+
+## Known Issues - Need Further Work ⚠️
+
+### 1. Horizontal vs Vertical Rails Asymmetry
+**Objects:** 0x22 (horizontal) vs vertical counterparts  
+**Issue:** Horizontal rails now work with CORNER+MIDDLE+END pattern, but vertical rails may not be updated to match.  
+**Files to check:**
+- `DrawDownwardsHasEdge1x1_*` routines
+- Look for routines mapped to 0x8A-0x8E (vertical equivalents)
+
+### 2. Diagonal Ceiling Outlines (0xA0-0xA3)
+**Issue:** Draw routine is correct (triangular fill), but outline dimensions still too large for selection purposes.  
+**Current state:** 
+- Draw: `count = (size & 0x0F) + 4`
+- Outline: `count = (size & 0x0F) + 2` (still too big)
+**Suggestion:** May need special handling in selection code rather than dimension calculation, since triangles only fill half the bounding box.
+
+### 3. Torch Object 0x3D
+**Issue:** Top half draws pegs instead of fire graphics.  
+**Likely cause:** ROM tile data issue - tiles at offset 0x807A may be incorrect or tile loading is wrong.  
+**Uses same routine as pillars (0x39).**
+
+### 4. Vertical Pegs 0x95/0x96
+**Issue:** Outline appears square (2x2) but should be vertical single row.  
+**May be UI/selection display issue rather than draw routine.**
+
+---
+
+## Pending Tasks 📋
+
+### High Priority
+1. **0xDC Chest Platform** - Complex routine with multiple segments, not currently working
+2. **Staircases audit** - Objects 0x12D-0x137, 0x21B-0x221, 0x226-0x229, 0x233
+
+### Medium Priority
+3. **Vertical rail patterns** - Match horizontal rail fixes
+4. **Pit edges** - Need specific object IDs to investigate
+
+### Low Priority
+5. **Diagonal ceiling selection** - May need UI-level fix
+
+---
+
+## Key Formulas Reference
+
+### Size Calculations (from ASM)
+
+| Pattern | Formula |
+|---------|---------|
+| GetSize_1to16 | `count = (size & 0x0F) + 1` |
+| GetSize_1to16_timesA | `count = (size & 0x0F + 1) * A` |
+| GetSize_1to15or26 | `count = size; if 0, count = 26` |
+| GetSize_1to15or32 | `count = size; if 0, count = 32` |
+| SuperSquare | `size_x = (size & 0x0F) + 1; size_y = ((size >> 4) & 0x0F) + 1` |
+
+### Rail Pattern Structure
+```
+[CORNER tile 0] -> [MIDDLE tile 1 × count] -> [END tile 2]
+```
+
+### Tile Ordering
+Most routines use **COLUMN-MAJOR** order: tiles advance down each column, then right.
+
+---
+
+## Files Modified
+
+- `src/zelda3/dungeon/object_drawer.cc` - Main draw routines and mappings
+- `src/zelda3/dungeon/object_drawer.h` - Added DrawActual4x4 declaration
+- `src/zelda3/dungeon/draw_routines/special_routines.cc` - Spiral stairs fix
+- `docs/internal/agents/draw_routine_tracker.md` - Tracking document
+
+---
+
+## Testing Notes
+
+- Log file at `logs/dungeon-object-draw.log` shows object draw data
+- Most testing was done on limited room set - need broader room testing
+- Use grep on log file to find specific object draws: `grep "obj=0xXX" logs/dungeon-object-draw.log`
+
+---
+
+## Next Steps for Continuation
+
+1. Test the rail fixes in rooms with both horizontal and vertical rails
+2. Find and fix the vertical rail equivalents (likely routines 23-28 or similar)
+3. Investigate 0xDC chest platform ASM in detail
+4. Consider UI-level fix for diagonal ceiling selection bounds

+# Gemini Pro 3 Antigravity - YAZE Development Session
+
+## Context
+
+You are working on **YAZE** (Yet Another Zelda3 Editor), a C++23 cross-platform ROM editor for The Legend of Zelda: A Link to the Past.
+
+**Your previous session accomplished:**
+- Fixed ASM version check regression using `OverworldVersionHelper` abstraction
+- Improved texture queueing in `Tile16Editor`
+- The insight: `0xFF >= 3` evaluates true, incorrectly treating vanilla ROMs as v3
+
+**Reference documentation available:**
+- `docs/internal/agents/gemini-overworld-system-reference.md` - Overworld architecture
+- `docs/internal/agents/gemini-dungeon-system-reference.md` - Dungeon architecture
+- `docs/internal/agents/gemini-build-setup.md` - Build commands
+
+---
+
+## Quick Start
+
+```bash
+# 1. Setup build directory (use dedicated dir, not user's build/)
+cmake --preset mac-dbg -B build_gemini
+
+# 2. Build editor
+cmake --build build_gemini -j8 --target yaze
+
+# 3. Run stable tests
+ctest --test-dir build_gemini -L stable -j4 --output-on-failure
+```
+
+---
+
+## Task Categories
+
+### Category A: Overworld Editor Gaps
+
+#### A1. Texture Queueing TODOs (6 locations)
+**File:** `src/app/editor/overworld/overworld_editor.cc`
+**Lines:** 1392, 1397, 1740, 1809, 1819, 1962
+
+These commented-out Renderer calls need to be converted to the Arena queue system:
+
+```cpp
+// BEFORE (blocking - commented out)
+// Renderer::Get().RenderBitmap(&bitmap_);
+
+// AFTER (non-blocking)
+gfx::Arena::Get().QueueTextureCommand(gfx::TextureCommand{
+    .operation = gfx::TextureOperation::kCreate,
+    .bitmap = &bitmap_,
+    .priority = gfx::TexturePriority::kHigh
+});
+```
+
+#### A2. Unimplemented Editor Methods
+**File:** `src/app/editor/overworld/overworld_editor.h` lines 82-87
+
+| Method | Status | Complexity |
+|--------|--------|------------|
+| `Undo()` | Returns `UnimplementedError` | Medium |
+| `Redo()` | Returns `UnimplementedError` | Medium |
+| `Cut()` | Returns `UnimplementedError` | Simple |
+| `Find()` | Returns `UnimplementedError` | Medium |
+
+#### A3. Entity Popup Static Variable Bug
+**File:** `src/app/editor/overworld/entity.cc`
+
+Multiple popups use `static` variables that persist across calls, causing state contamination:
+
+```cpp
+// CURRENT (BUG)
+bool DrawExitEditorPopup() {
+  static bool set_done = false;  // Persists! Wrong entity data shown
+  static int doorType = ...;
+}
+
+// FIX: Use local variables or proper state management
+bool DrawExitEditorPopup(ExitEditorState& state) {
+  // state is passed in, not static
+}
+```
+
+#### A4. Exit Editor Unconnected UI
+**File:** `src/app/editor/overworld/entity.cc` lines 216-264
+
+UI elements exist but aren't connected to data:
+- Door type editing (Wooden, Bombable, Sanctuary, Palace)
+- Door X/Y position
+- Center X/Y, Link posture, sprite/BG GFX, palette
+
+---
+
+### Category B: Dungeon Object Rendering
+
+#### B1. BothBG Dual-Layer Stubs (4 locations)
+**File:** `src/zelda3/dungeon/object_drawer.cc`
+
+These routines should draw to BOTH BG1 and BG2 but only accept one buffer:
+
+| Line | Routine | Status |
+|------|---------|--------|
+| 375-381 | `DrawRightwards2x4spaced4_1to16_BothBG` | STUB |
+| 437-442 | `DrawDiagonalAcute_1to16_BothBG` | STUB |
+| 444-449 | `DrawDiagonalGrave_1to16_BothBG` | STUB |
+| 755-761 | `DrawDownwards4x2_1to16_BothBG` | STUB |
+
+**Fix:** Change signature to accept both buffers:
+```cpp
+// BEFORE
+void DrawRightwards2x4spaced4_1to16_BothBG(
+    const RoomObject& obj, gfx::BackgroundBuffer& bg, ...);
+
+// AFTER
+void DrawRightwards2x4spaced4_1to16_BothBG(
+    const RoomObject& obj,
+    gfx::BackgroundBuffer& bg1,
+    gfx::BackgroundBuffer& bg2, ...);
+```
+
+#### B2. Diagonal Routines Unclear Logic
+**File:** `src/zelda3/dungeon/object_drawer.cc` lines 401-435
+
+Issues with `DrawDiagonalAcute_1to16` and `DrawDiagonalGrave_1to16`:
+- Hardcoded `size + 6` and 5 iterations (why?)
+- Coordinate formula `obj.y_ + (i - s)` can produce negative Y
+- No bounds checking
+- Only uses 4 tiles from larger span
+
+#### B3. CustomDraw and DoorSwitcherer Stubs
+**File:** `src/zelda3/dungeon/object_drawer.cc`
+- Lines 524-532: `CustomDraw` - only draws first tile
+- Lines 566-575: `DrawDoorSwitcherer` - only draws first tile
+
+#### B4. Unknown Object Names (30+ items)
+**File:** `src/zelda3/dungeon/room_object.h`
+
+See `gemini-dungeon-system-reference.md` section 7 for full list of objects needing in-game verification.
+
+---
+
+### Category C: Already Complete (Verification Only)
+
+#### C1. Tile16Editor Undo/Redo - COMPLETE
+**File:** `src/app/editor/overworld/tile16_editor.cc`
+- `SaveUndoState()` at lines 547, 1476, 1511, 1546, 1586, 1620
+- `Undo()` / `Redo()` at lines 1707-1760
+- Ctrl+Z/Ctrl+Y at lines 224-231
+- UI button at line 1101
+
+**No work needed** - just verify it works.
+
+#### C2. Entity Deletion Pattern - CORRECT
+**File:** `src/app/editor/overworld/entity.cc` line 319
+
+The TODO comment is misleading. The `deleted` flag pattern IS correct for ROM editors:
+- Entities at fixed ROM offsets can't be "removed"
+- `entity_operations.cc` reuses deleted slots
+- Just clarify the comment if desired
+
+---
+
+## Prioritized Task List
+
+### Phase 1: High Impact (45-60 min)
+1. **A1** - Texture queueing (6 TODOs) - Prevents UI freezes
+2. **B1** - BothBG dual-layer stubs (4 routines) - Completes dungeon rendering
+
+### Phase 2: Medium Impact (30-45 min)
+3. **A3** - Entity popup static variable bug - Fixes data corruption
+4. **B2** - Diagonal routine logic - Fixes rendering artifacts
+
+### Phase 3: Polish (30+ min)
+5. **A2** - Implement Undo/Redo for OverworldEditor
+6. **A4** - Connect exit editor UI to data
+7. **B3** - Implement CustomDraw/DoorSwitcherer
+
+### Stretch Goals
+8. **B4** - Verify unknown object names (requires game testing)
+9. E2E cinematic tests (see `docs/internal/testing/dungeon-gui-test-design.md`)
+
+---
+
+## Code Patterns
+
+### Texture Queue (Use This!)
+```cpp
+gfx::Arena::Get().QueueTextureCommand(gfx::TextureCommand{
+    .operation = gfx::TextureOperation::kCreate,  // or kUpdate
+    .bitmap = &bitmap_,
+    .priority = gfx::TexturePriority::kHigh
+});
+```
+
+### Version-Aware Code
+```cpp
+auto version = OverworldVersionHelper::GetVersion(*rom_);
+if (OverworldVersionHelper::SupportsAreaEnum(version)) {
+  // v3+ only
+}
+```
+
+### Error Handling
+```cpp
+absl::Status MyFunction() {
+  ASSIGN_OR_RETURN(auto data, LoadData());
+  RETURN_IF_ERROR(ProcessData(data));
+  return absl::OkStatus();
+}
+```
+
+---
+
+## Validation
+

+## 2. ZSCustomOverworld Version System
+
+### Version Detection
+```cpp
+// ROM address for version byte
+constexpr int OverworldCustomASMHasBeenApplied = 0x140145;
+
+// Version values
+0xFF = Vanilla ROM (unpatched)
+0x01 = ZSCustomOverworld v1
+0x02 = ZSCustomOverworld v2
+0x03 = ZSCustomOverworld v3+
+```
+
+### Feature Matrix
+
+| Feature | Vanilla | v1 | v2 | v3 |
+|---------|---------|----|----|-----|
+| Basic map editing | Y | Y | Y | Y |
+| Large maps (2x2) | Y | Y | Y | Y |
+| Expanded pointers (0x130000+) | - | Y | Y | Y |
+| Custom BG colors | - | - | Y | Y |
+| Main palette per area | - | - | Y | Y |
+| Wide areas (2x1) | - | - | - | Y |
+| Tall areas (1x2) | - | - | - | Y |
+| Custom tile GFX (8 per map) | - | - | - | Y |
+| Animated GFX | - | - | - | Y |
+| Subscreen overlays | - | - | - | Y |
+
+### OverworldVersionHelper API
+```cpp
+// src/zelda3/overworld/overworld_version_helper.h
+
+enum class OverworldVersion { kVanilla=0, kZSCustomV1=1, kZSCustomV2=2, kZSCustomV3=3 };
+enum class AreaSizeEnum { SmallArea=0, LargeArea=1, WideArea=2, TallArea=3 };
+
+// Detection
+static OverworldVersion GetVersion(const Rom& rom);
+static uint8_t GetAsmVersion(const Rom& rom);
+
+// Feature gates (use these, not raw version checks!)
+static bool SupportsAreaEnum(OverworldVersion v);      // v3 only
+static bool SupportsExpandedSpace(OverworldVersion v); // v1+
+static bool SupportsCustomBGColors(OverworldVersion v);// v2+
+static bool SupportsCustomTileGFX(OverworldVersion v); // v3 only
+static bool SupportsAnimatedGFX(OverworldVersion v);   // v3 only
+static bool SupportsSubscreenOverlay(OverworldVersion v); // v3 only
+```
+
+---
+
+## 3. Tile System Architecture
+
+### Tile Hierarchy
+```
+Tile8 (8x8 pixels) - Base SNES tile
+  ↓
+Tile16 (16x16 pixels) - 2x2 grid of Tile8s
+  ↓
+Tile32 (32x32 pixels) - 2x2 grid of Tile16s
+  ↓
+Map Screen (256x256 pixels) - 8x8 grid of Tile32s
+```
+
+### Tile16 Structure
+```cpp
+// src/app/gfx/types/snes_tile.h
+
+class TileInfo {
+  uint16_t id_;              // 9-bit tile8 ID (0-511)
+  uint8_t palette_;          // 3-bit palette (0-7)
+  bool over_;                // Priority flag
+  bool vertical_mirror_;     // Y-flip
+  bool horizontal_mirror_;   // X-flip
+};
+
+class Tile16 {
+  TileInfo tile0_;  // Top-left
+  TileInfo tile1_;  // Top-right
+  TileInfo tile2_;  // Bottom-left
+  TileInfo tile3_;  // Bottom-right
+};
+
+// ROM storage: 8 bytes per Tile16 at 0x78000 + (ID * 8)
+// Total: 4,096 Tile16s (0x0000-0x0FFF)
+```
+
+### Tile16Editor Features (COMPLETE)
+The Tile16Editor at `tile16_editor.cc` is **fully implemented** with:
+
+- **Undo/Redo System** (lines 1681-1760)
+  - `SaveUndoState()` - captures current state
+  - `Undo()` / `Redo()` - restore states
+  - Ctrl+Z / Ctrl+Y keyboard shortcuts
+  - 50-state stack with rate limiting
+
+- **Clipboard Operations**
+  - Copy/Paste Tile16s
+  - 4 scratch space slots
+
+- **Editing Features**
+  - Tile8 composition into Tile16
+  - Flip horizontal/vertical
+  - Palette cycling (0-7)
+  - Fill with single Tile8
+
+---
+
+## 4. Map Organization
+
+### Index Scheme
+```
+Index 0x00-0x3F: Light World (64 maps, 8x8 grid)
+Index 0x40-0x7F: Dark World (64 maps, 8x8 grid)
+Index 0x80-0x9F: Special World (32 maps, 8x4 grid)
+
+Total: 160 maps
+
+Grid position: X = index % 8, Y = index / 8
+World position: X * 512 pixels, Y * 512 pixels
+```
+
+### Multi-Area Maps
+```cpp
+enum class AreaSizeEnum {
+  SmallArea = 0,  // 1x1 screen (standard)
+  LargeArea = 1,  // 2x2 screens (4 quadrants)
+  WideArea = 2,   // 2x1 screens (v3 only)
+  TallArea = 3,   // 1x2 screens (v3 only)
+};
+
+// IMPORTANT: Always use ConfigureMultiAreaMap() for size changes!
+// Never set area_size_ directly - it handles parent IDs and ROM persistence
+absl::Status Overworld::ConfigureMultiAreaMap(int parent_index, AreaSizeEnum size);
+```
+
+---
+
+## 5. Entity System
+
+### Entity Types
+| Type | Storage | Count | ROM Address |
+|------|---------|-------|-------------|
+| Entrances | `all_entrances_` | ~129 | 0xDB96F+ |
+| Holes | `all_holes_` | ~19 | 0xDB800+ |
+| Exits | `all_exits_` | ~79 | 0x15D8A+ |
+| Items | `all_items_` | Variable | 0xDC2F9+ |
+| Sprites | `all_sprites_[3]` | Variable | 0x4C881+ |
+
+### Entity Deletion Pattern
+Entities use a `deleted` flag pattern - this is **CORRECT** for ROM editors:
+```cpp
+// Entities live at fixed ROM offsets, cannot be truly "removed"
+// Setting deleted = true marks them as inactive
+// entity_operations.cc reuses deleted slots for new entities
+item.deleted = true;  // Proper pattern
+
+// Renderer skips deleted entities (overworld_entity_renderer.cc)
+if (!item.deleted) { /* render */ }
+```
+
+---
+
+## 6. Graphics Loading Pipeline
+
+### Load Sequence
+```
+1. Overworld::Load(rom)
+   └── LoadOverworldMaps()
+         └── For each map (0-159):
+               └── OverworldMap::ctor()
+                     ├── LoadAreaInfo()
+                     └── LoadCustomOverworldData() [v3]
+
+2. On map access: EnsureMapBuilt(map_index)
+   └── BuildMap()
+         ├── LoadAreaGraphics()
+         ├── BuildTileset()
+         ├── BuildTiles16Gfx()
+         ├── LoadPalette()
+         ├── LoadOverlay()
+         └── BuildBitmap()
+```
+
+### Texture Queue System
+Use deferred texture loading via `gfx::Arena`:
+```cpp
+// CORRECT: Non-blocking, uses queue
+gfx::Arena::Get().QueueTextureCommand(gfx::TextureCommand{
+    .operation = gfx::TextureOperation::kCreate,
+    .bitmap = &some_bitmap_,
+    .priority = gfx::TexturePriority::kHigh
+});
+
+// WRONG: Blocking, causes UI freeze
+Renderer::Get().RenderBitmap(&some_bitmap_);
+```
+
+---
+
+## 7. ROM Addresses (Key Locations)
+
+### Vanilla Addresses
+```cpp
+// Tile data
+kTile16Ptr = 0x78000              // Tile16 definitions
+kOverworldMapSize = 0x12844       // Map size bytes
+
+// Graphics & Palettes
+kAreaGfxIdPtr = 0x7C9C            // Area graphics IDs
+kOverworldMapPaletteGroup = 0x7D1C // Palette IDs
+
+// Entities
+kOverworldEntranceMap = 0xDB96F   // Entrance data
+kOverworldExitRooms = 0x15D8A     // Exit room IDs
+kOverworldItemPointers = 0xDC2F9  // Item pointers
+```
+
+### Expanded Addresses (v1+)
+```cpp
+// Custom data at 0x140000+
+OverworldCustomASMHasBeenApplied = 0x140145  // Version byte
+OverworldCustomAreaSpecificBGPalette = 0x140000  // BG colors (160*2)
+OverworldCustomMainPaletteArray = 0x140160   // Main palettes (160)
+OverworldCustomAnimatedGFXArray = 0x1402A0   // Animated GFX (160)
+OverworldCustomTileGFXGroupArray = 0x140480  // Tile GFX (160*8)
+OverworldCustomSubscreenOverlayArray = 0x140340 // Overlays (160*2)
+kOverworldMapParentIdExpanded = 0x140998     // Parent IDs (160)
+kOverworldMessagesExpanded = 0x1417F8        // Messages (160*2)
+```
+
+---
+
+## 8. Known Gaps in OverworldEditor
+
+### Critical: Texture Queueing TODOs (6 locations)
+```cpp
+// overworld_editor.cc - these Renderer calls need to be converted:
+Line 1392: // TODO: Queue texture for later rendering
+Line 1397: // TODO: Queue texture for later rendering
+Line 1740: // TODO: Queue texture for later rendering
+Line 1809: // TODO: Queue texture for later rendering
+Line 1819: // TODO: Queue texture for later rendering
+Line 1962: // TODO: Queue texture for later rendering
+```
+
+### Unimplemented Core Methods
+```cpp
+// overworld_editor.h lines 82-87
+Undo()  → Returns UnimplementedError
+Redo()  → Returns UnimplementedError
+Cut()   → Returns UnimplementedError
+Find()  → Returns UnimplementedError
+```
+
+### Entity Popup Static Variable Bug
+```cpp
+// entity.cc - Multiple popups use static variables that persist
+// Causes state contamination when editing multiple entities
+bool DrawExitEditorPopup() {
+  static bool set_done = false;  // BUG: persists across calls
+  static int doorType = ...;      // BUG: wrong entity's data shown
+}
+```
+
+### Exit Editor Unimplemented Features
+```cpp
+// entity.cc lines 216-264
+// UI exists but not connected to data:
+- Door type editing (Wooden, Bombable, Sanctuary, Palace)
+- Door X/Y position
+- Center X/Y, Link posture, sprite/BG GFX, palette
+```
+
+---
+
+## 9. Code Patterns to Follow
+
+### Graphics Refresh
+```cpp
+// 1. Update model
+map.SetProperty(new_value);
+
+// 2. Reload from ROM
+map.LoadAreaGraphics();
+
+// 3. Queue texture update (NOT RenderBitmap!)
+gfx::Arena::Get().QueueTextureCommand(gfx::TextureCommand{
+    .operation = gfx::TextureOperation::kUpdate,
+    .bitmap = &map_bitmap_,
+    .priority = gfx::TexturePriority::kHigh
+});
+```
+
+### Version-Aware Code
+```cpp
+auto version = OverworldVersionHelper::GetVersion(*rom_);
+
+// Use semantic helpers, not raw version checks
+if (OverworldVersionHelper::SupportsAreaEnum(version)) {
+  // v3+ only code
+}
+```
+
+### Entity Rendering Colors (0.85f alpha)
+```cpp
+ImVec4 entrance_color(1.0f, 0.85f, 0.0f, 0.85f);  // Yellow-gold
+ImVec4 exit_color(0.0f, 1.0f, 1.0f, 0.85f);       // Cyan
+ImVec4 item_color(1.0f, 0.0f, 0.0f, 0.85f);       // Red
+ImVec4 sprite_color(1.0f, 0.0f, 1.0f, 0.85f);     // Magenta
+```
+
+---
+
+## 10. Testing
+
+### Run Overworld Tests
+```bash
+# Unit tests
+ctest --test-dir build -R "Overworld" -V
+
+# Regression tests
+ctest --test-dir build -R "OverworldRegression" -V
+```

+# Gemini 3 Pro Prompt: Overworld Regression Fix and Improvements
+
+## Context
+
+You are working on **yaze** (Yet Another Zelda3 Editor), a C++23 ROM editor for The Legend of Zelda: A Link to the Past. A regression has been introduced that breaks loading of custom ROMs like "Oracle of Secrets" ROM hack.
+
+## Primary Bug: ASM Version Check Inconsistency
+
+### Root Cause Analysis
+
+The recent refactoring introduced `OverworldVersionHelper` for centralized ROM version detection, but **not all code paths were updated to use it consistently**. Specifically:
+
+**In `src/zelda3/overworld/overworld.cc:71`:**
+```cpp
+uint8_t asm_version = (*rom_)[OverworldCustomASMHasBeenApplied];
+if (asm_version >= 3) {  // BUG: 0xFF (255) is >= 3!
+  AssignMapSizes(overworld_maps_);
+} else {
+  FetchLargeMaps();  // Vanilla ROMs need this path
+}
+```
+
+**The bug**: `asm_version >= 3` evaluates to `true` for vanilla ROMs where `asm_version == 0xFF` (255), causing vanilla ROMs and custom ROMs without ZScream ASM patches to incorrectly call `AssignMapSizes()` instead of `FetchLargeMaps()`.
+
+**Other places correctly check**:
+```cpp
+if (asm_version >= 3 && asm_version != 0xFF) { ... }  // Correct
+```
+
+### Inconsistent Locations Found
+
+Search results showing mixed patterns:
+- `overworld.cc:71` - **BUG**: `if (asm_version >= 3)` - missing `&& asm_version != 0xFF`
+- `overworld.cc:449` - **BUG**: `if (expanded_flag != 0x04 || asm_version >= 3)` - missing check
+- `overworld.cc:506` - **BUG**: similar pattern
+- `overworld.cc:281` - **CORRECT**: `(asm_version < 3 || asm_version == 0xFF)`
+- `overworld.cc:373` - **CORRECT**: `if (asm_version >= 3 && asm_version != 0xFF)`
+- Other files also have inconsistencies
+
+## Your Task
+
+### Phase 1: Fix the Regression (CRITICAL)
+
+1. **Update all ASM version checks** in overworld code to either:
+   - Use `OverworldVersionHelper::GetVersion()` and semantic checks like `SupportsAreaEnum()`, OR
+   - Consistently use `asm_version >= 3 && asm_version != 0xFF` pattern
+
+2. **Key files to fix**:
+   - `src/zelda3/overworld/overworld.cc`
+   - `src/zelda3/overworld/overworld_map.cc`
+   - `src/zelda3/overworld/overworld_item.cc`
+
+3. **Priority fixes in `overworld.cc`**:
+   - Line 71: Change to `if (asm_version >= 3 && asm_version != 0xFF)`
+   - Line 449: Add `&& asm_version != 0xFF` check
+   - Line 506: Add `&& asm_version != 0xFF` check
+   - Review all other locations from the grep results
+
+### Phase 2: Standardize Version Checking (Recommended)
+
+Replace all raw `asm_version` checks with `OverworldVersionHelper`:
+
+**Instead of:**
+```cpp
+uint8_t asm_version = (*rom_)[OverworldCustomASMHasBeenApplied];
+if (asm_version >= 3 && asm_version != 0xFF) {
+```
+
+**Use:**
+```cpp
+auto version = OverworldVersionHelper::GetVersion(*rom_);
+if (OverworldVersionHelper::SupportsAreaEnum(version)) {
+```
+
+This centralizes the logic and prevents future inconsistencies.
+
+### Phase 3: Add Unit Tests
+
+Create tests in `test/unit/zelda3/overworld_test.cc` to verify:
+1. Vanilla ROM (0xFF) uses `FetchLargeMaps()` path
+2. ZScream v3 ROM (0x03) uses `AssignMapSizes()` path
+3. Custom ROMs with other values behave correctly

+
+## Commits That Introduced the Regression
+
+1. `1e39df88a3` - "refactor: enhance overworld entity properties and version handling"
+   - Introduced `OverworldVersionHelper`
+   - 15 files changed, +546 -282 lines
+
+2. `5894809aaf` - "refactor: improve overworld map version handling and code organization"
+   - Updated `OverworldMap` to use version helper
+   - 4 files changed, +145 -115 lines
+
+## Build & Test Commands
+
+```bash
+# Configure
+cmake --preset mac-dbg
+
+# Build
+cmake --build build --target yaze -j8
+
+# Run unit tests
+ctest --test-dir build -L stable -R overworld
+
+# Run the app to test loading
+./build/bin/Debug/yaze.app/Contents/MacOS/yaze --rom_file=/path/to/oracle_of_secrets.sfc
+```
+
+## Success Criteria
+
+1. Oracle of Secrets ROM loads correctly in the Overworld Editor
+2. Vanilla ALTTP ROMs continue to work
+3. ZScream v3 patched ROMs continue to work
+4. All existing unit tests pass
+5. No new compiler warnings
+
+## Additional Context
+
+- The editor supports multiple ROM types: Vanilla, ZScream v1/v2/v3 patched ROMs, and custom hacks
+- `OverworldCustomASMHasBeenApplied` address (0x130000) stores the version byte
+- 0xFF = vanilla (no patches), 1-2 = legacy ZScream, 3 = current ZScream
+- "Oracle of Secrets" is a popular ROM hack that may use 0xFF or a custom value
+
+## Code Quality Requirements
+
+- Follow Google C++ Style Guide
+- Use `absl::Status` for error handling
+- Run clang-format before committing
+- Update CLAUDE.md coordination board when done

+# Gemini 3 Pro - v0.4.0 Development Session
+
+## Context
+
+You are working on **YAZE** (Yet Another Zelda3 Editor), a C++23 cross-platform ROM editor for The Legend of Zelda: A Link to the Past.
+
+**Current Situation:**
+- **v0.3.9**: CI/CD hotfix running (another agent handling - DO NOT TOUCH)
+- **v0.4.0**: Your focus - "Editor Stability & OOS Support"
+- **Goal**: Unblock Oracle of Secrets (OOS) ROM hack development
+
+---
+
+## Quick Start
+
+```bash
+# Use dedicated build directory (DO NOT use build/ or build_agent/)
+cmake --preset mac-dbg -B build_gemini
+cmake --build build_gemini -j8 --target yaze
+
+# Run stable tests
+ctest --test-dir build_gemini -L stable -j4 --output-on-failure
+```
+

+
+## Completed Work
+
+### Priority 2: Message Editor - Expanded BIN Export [COMPLETE]
+
+**Completed by Gemini 3 Pro:**
+
+1. **JSON Export Implementation** (`message_data.h/cc`):
+   - Added `SerializeMessagesToJson()` - Converts `MessageData` vector to JSON array
+   - Added `ExportMessagesToJson()` - Writes JSON file with error handling
+   - Uses nlohmann/json library with 2-space pretty printing
+
+2. **File Dialog Integration** (`message_editor.cc:317-376`):
+   - "Load Expanded Message" - Opens file dialog to load BIN
+   - "Save Expanded Messages" - Saves to remembered path
+   - "Save As..." - Prompts for new path
+   - "Export to JSON" - JSON export with file dialog
+
+3. **Path Persistence**:
+   - `expanded_message_path_` member stores last used path
+   - Reuses path for subsequent saves
+
+4. **SaveExpandedMessages() Implementation** (`message_editor.cc:521-571`):
+   - Uses `expanded_message_bin_` member for ROM-like storage
+   - Handles buffer expansion for new messages
+   - Writes terminator byte (0xFF) after data
+
+### Priority 1: Dungeon Editor - SaveDungeon() [IN PROGRESS]
+
+**Completed by Gemini 3 Pro:**
+
+1. **SaveDungeon() Implementation** (`dungeon_editor_system.cc:44-59`):
+   - No longer a stub! Loops through all 296 rooms
+   - Calls `SaveRoomData()` for each room
+   - Tracks dirty state and last save time
+
+2. **SaveObjects() Implementation** (`room.cc:873-925`):
+   - Properly calculates available space via `CalculateRoomSize()`
+   - Validates encoded size fits before writing
+   - Returns `OutOfRangeError` if data too large
+
+3. **SaveSprites() Implementation** (`room.cc:927-999`):
+   - Calculates sprite space from pointer table
+   - Handles sortsprites byte
+   - Returns `OutOfRangeError` if data too large
+
+4. **New Tests** (`test/unit/zelda3/dungeon/dungeon_save_test.cc`):
+   - `SaveObjects_FitsInSpace` - verifies normal save works
+   - `SaveObjects_TooLarge` - verifies overflow detection
+   - `SaveSprites_FitsInSpace` - verifies normal save works
+   - `SaveSprites_TooLarge` - verifies overflow detection
+
+**Tests Pass:**
+```bash
+./build_gemini/bin/Debug/yaze_test_stable --gtest_filter="*DungeonSave*"
+# [  PASSED  ] 4 tests.
+```
+
+---
+
+## Testing Instructions
+
+### Build and Run Tests
+
+```bash
+# Build test target (uses existing build_gemini)
+cmake --build build_gemini --target yaze_test_stable -j8

+```
+
+### Known Test Issues (Pre-existing)
+
+**FAILING:** `RoomObjectEncodingTest.DetermineObjectTypeType2`
+- Location: `test/unit/zelda3/dungeon/room_object_encoding_test.cc:29-31`
+- Issue: `DetermineObjectType()` returns 1 instead of 2 for bytes 0xFC, 0xFD, 0xFF
+- Status: Pre-existing failure, NOT caused by your changes
+- Action: Ignore unless you're specifically working on object type detection
+
+### Test File Locations

+
+## Your Priorities (Pick One)
+
+### Priority 1: Dungeon Editor - Save Infrastructure [COMPLETE] ✅
+
+**Completed by Gemini 3 Pro:**
+
+1. **SaveRoomData() Implementation** (`dungeon_editor_system.cc:914-973`):
+   - ✅ Detects if room is currently being edited in UI
+   - ✅ Uses editor's in-memory `Room` object (contains unsaved changes)
+   - ✅ Syncs sprites from `DungeonEditorSystem` to `Room` before saving
+   - ✅ Selectively saves objects only for current room (optimization)
+
+2. **UI Integration** (`dungeon_editor_v2.cc:244-291`):
+   - ✅ `Save()` method calls `SaveDungeon()` correctly
+   - ✅ Palette saving via `PaletteManager`
+   - ✅ Room objects saved via `Room::SaveObjects()`
+   - ✅ Sprites saved via `DungeonEditorSystem::SaveRoom()`
+
+3. **Edge Cases Verified:**
+   - ✅ Current room with unsaved changes
+   - ✅ Non-current rooms (sprite-only save)
+   - ✅ Multiple rooms open in tabs
+   - ✅ Empty sprite lists
+
+**Audit Report:** `zscow_audit_report.md` (artifact)
+
+**Minor Improvements Recommended:**
+- Add integration tests for `DungeonEditorSystem` save flow
+- Remove redundant `SaveObjects()` call in `DungeonEditorV2::Save()`
+- Document stub methods
+
+**Test your changes:**
+```bash
+./build_gemini/bin/Debug/yaze_test_stable --gtest_filter="*DungeonSave*:*RoomManipulation*"
+```
+
+---
+
+### Priority 3: ZSCOW Audit [COMPLETE] ✅
+
+**Completed by Gemini 3 Pro:**
+
+#### 1. Version Detection - VERIFIED ✅
+
+**Implementation:** `overworld_version_helper.h:51-71`
+
+| ASM Byte | Version | Status |
+|----------|---------|--------|
+| `0xFF` | Vanilla | ✅ Correct |
+| `0x00` | Vanilla | ✅ **CORRECT** - Expanded ROMs are zero-filled |
+| `0x01` | v1 | ✅ Verified |
+| `0x02` | v2 | ⚠️ Not tested (no v2 ROM available) |
+| `0x03+` | v3 | ✅ Verified |
+
+**Task 1: Version 0x00 Edge Case - RESOLVED ✅**
+- **Answer:** Treating `0x00` as vanilla is **CORRECT**
+- **Rationale:** When vanilla ROM is expanded to 2MB, new space is zero-filled
+- **Address:** `0x140145` is in expanded space (beyond 1MB)
+- **Tests Added:** 5 comprehensive tests in `overworld_version_helper_test.cc`
+- **Bounds Check Added:** Prevents crashes on small ROMs
+
+**Task 2: Death Mountain GFX TODO - DOCUMENTED ⚠️**
+
+**Location:** `overworld_map.cc:595-602`
+
+- **Current logic:** Checks parent ranges `0x03-0x07`, `0x0B-0x0E` (LW), `0x43-0x47`, `0x4B-0x4E` (DW)
+- **Recommended:** Only check `0x03`, `0x05`, `0x07` (LW) and `0x43`, `0x45`, `0x47` (DW)
+- **Rationale:** Matches ZScream 3.0.4+ behavior, handles non-large DM areas correctly
+- **Impact:** Low risk improvement
+- **Status:** Documented in audit report, not implemented yet
+
+**Task 3: ConfigureMultiAreaMap - FULLY VERIFIED ✅**
+
+**Location:** `overworld.cc:267-422`
+
+- ✅ Vanilla ROM: Correctly rejects Wide/Tall areas
+- ✅ v1/v2 ROM: Same as vanilla (no area enum support)
+- ✅ v3 ROM: All 4 sizes work (Small, Large, Wide, Tall)
+- ✅ Sibling cleanup: Properly resets all quadrants when shrinking Large→Small
+- ✅ Edge maps: Boundary conditions handled safely
+
+**Task 4: Special World Hardcoded Cases - VERIFIED ✅**
+
+**Location:** `overworld_map.cc:202-293`
+
+- ✅ Triforce room (`0x88`, `0x93`): Special graphics `0x51`, palette `0x00`
+- ✅ Master Sword area (`0x80`): Special GFX group
+- ✅ Zora's Domain (`0x81`, `0x82`, `0x89`, `0x8A`): Sprite GFX `0x0E`
+- ✅ Version-aware logic for v3 vs vanilla/v2
+
+**Audit Report:** `zscow_audit_report.md` (artifact)
+
+**Test Results:**
+```bash
+./build_gemini/bin/Debug/yaze_test_stable --gtest_filter="OverworldVersionHelperTest*"
+# [  PASSED  ] 5 tests.
+```
+
+**Overall Assessment:** ZSCOW implementation is production-ready with one low-priority enhancement (Death Mountain GFX logic).
+
+---
+
+### Priority 4: Agent Inspection - Wire Real Data [MEDIUM] - DETAILED
+
+**Problem:** CLI inspection commands return stub output. Helper functions exist but aren't connected.
+
+#### Overworld Command Handlers (`src/cli/handlers/game/overworld.cc`)
+
+| Line | Handler | Status | Helper to Use |
+|------|---------|--------|---------------|
+| 33 | `OverworldGetTileCommandHandler` | TODO | Manual ROM read |
+| 84 | `OverworldSetTileCommandHandler` | TODO | Manual ROM write |
+| 162 | `OverworldFindTileCommandHandler` | TODO | `FindTileMatches()` |
+| 325 | `OverworldDescribeMapCommandHandler` | TODO | `BuildMapSummary()` |
+| 508 | `OverworldListWarpsCommandHandler` | TODO | `CollectWarpEntries()` |
+| 721 | `OverworldSelectRectCommandHandler` | TODO | N/A (GUI) |
+| 759 | `OverworldScrollToCommandHandler` | TODO | N/A (GUI) |
+| 794 | `OverworldSetZoomCommandHandler` | TODO | N/A (GUI) |
+| 822 | `OverworldGetVisibleRegionCommandHandler` | TODO | N/A (GUI) |
+
+#### Dungeon Command Handlers (`src/cli/handlers/game/dungeon_commands.cc`)
+
+| Line | Handler | Status |
+|------|---------|--------|
+| 36 | Sprite listing | TODO - need `Room::sprites()` |
+| 158 | Object listing | TODO - need `Room::objects()` |
+| 195 | Tile data | TODO - need `Room::floor1()`/`floor2()` |
+| 237 | Property setting | TODO - need `Room::set_*()` methods |
+
+#### Available Helper Functions (`overworld_inspect.h`)
+
+These are fully implemented and ready to use:
+
+```cpp
+// Build complete map metadata summary
+absl::StatusOr<MapSummary> BuildMapSummary(zelda3::Overworld& overworld, int map_id);
+
+// Find all warps matching query (entrances, exits, holes)
+absl::StatusOr<std::vector<WarpEntry>> CollectWarpEntries(
+    const zelda3::Overworld& overworld, const WarpQuery& query);
+
+// Find all occurrences of a tile16 ID
+absl::StatusOr<std::vector<TileMatch>> FindTileMatches(
+    zelda3::Overworld& overworld, uint16_t tile_id, const TileSearchOptions& options);
+
+// Get sprites on overworld maps
+absl::StatusOr<std::vector<OverworldSprite>> CollectOverworldSprites(
+    const zelda3::Overworld& overworld, const SpriteQuery& query);
+
+// Get entrance details by ID
+absl::StatusOr<EntranceDetails> GetEntranceDetails(
+    const zelda3::Overworld& overworld, uint8_t entrance_id);
+
+// Analyze how often a tile is used
+absl::StatusOr<TileStatistics> AnalyzeTileUsage(
+    zelda3::Overworld& overworld, uint16_t tile_id, const TileSearchOptions& options);
+```
+
+#### Example Fix Pattern
+
+```cpp
+// BEFORE (broken):
+absl::Status OverworldFindTileCommandHandler::Execute(
+    CommandContext& context, std::ostream& output) {
+  output << "Placeholder: would find tile...";  // STUB!
+  return absl::OkStatus();
+}
+
+// AFTER (working):
+absl::Status OverworldFindTileCommandHandler::Execute(
+    CommandContext& context, std::ostream& output) {
+  auto tile_id_str = context.GetArgument("tile_id");
+  ASSIGN_OR_RETURN(auto tile_id, ParseHexOrDecimal(tile_id_str));
+
+  TileSearchOptions options;
+  if (auto world = context.GetOptionalArgument("world")) {
+    ASSIGN_OR_RETURN(options.world, ParseWorldSpecifier(*world));
+  }
+
+  ASSIGN_OR_RETURN(auto matches,
+      overworld::FindTileMatches(context.overworld(), tile_id, options));
+
+  output << "Found " << matches.size() << " occurrences:\n";
+  for (const auto& match : matches) {
+    output << absl::StrFormat("  Map %d (%s): (%d, %d)\n",
+        match.map_id, WorldName(match.world), match.local_x, match.local_y);
+  }
+  return absl::OkStatus();
+}
+```
+
+#### Priority Order
+
+1. `OverworldDescribeMapCommandHandler` - Most useful for agents
+2. `OverworldFindTileCommandHandler` - Common query
+3. `OverworldListWarpsCommandHandler` - Needed for navigation
+4. Dungeon sprite/object listing - For dungeon editing support
+

+
+---
+
+## Code Style
+
+- Use `absl::Status` and `absl::StatusOr<T>` for error handling
+- Macros: `RETURN_IF_ERROR()`, `ASSIGN_OR_RETURN()`
+- Format: `cmake --build build_gemini --target format`
+- Follow Google C++ Style Guide

+2. **Read the relevant files** before making changes
+3. **Run tests frequently** (`ctest --test-dir build_gemini -L stable`)
+4. **Commit with clear messages** following conventional commits (`fix:`, `feat:`)
+5. **Don't touch CI/CD** - that's being handled separately
+
+---
+
+## Current State of Uncommitted Work
+
+The working tree has changes you should be aware of:
+- `tile16_editor.cc` - Texture queueing improvements
+- `entity.cc/h` - Sprite movement fixes
+- `overworld_editor.cc` - Entity rendering
+- `overworld_map.cc` - Map rendering
+- `object_drawer.cc/h` - Dungeon objects
+
+Review these before making overlapping changes.
+
+---
+
+## Success Criteria
+
+When you're done, one of these should be true:
+- [x] ~~Dungeon save actually persists changes to ROM~~ **COMPLETE** ✅
+- [x] ~~Message editor can export expanded BIN files~~ **COMPLETE** ✅
+- [x] ~~ZSCOW loads correctly for vanilla + v1/v2/v3 ROMs~~ **COMPLETE** ✅
+- [ ] Agent inspection returns real data

+
+Objects are stored as 3 bytes in ROM with three distinct encoding types:
+
+#### Type 1: Standard Objects (ID 0x00-0xFF)
+```
+Byte format: xxxxxxss | yyyyyyss | iiiiiiii
+             b1         b2         b3
+
+Decoding:
+  x = (b1 & 0xFC) >> 2        // 6 bits (0-63)
+  y = (b2 & 0xFC) >> 2        // 6 bits (0-63)
+  size = ((b1 & 0x03) << 2) | (b2 & 0x03)  // 4 bits (0-15)
+  id = b3                      // 8 bits
+```
+
+#### Type 2: Extended Objects (ID 0x100-0x1FF)
+```
+Indicator: b1 >= 0xFC
+
+Byte format: 111111xx | xxxxyyyy | yyiiiiii
+             b1         b2         b3
+
+Decoding:
+  id = (b3 & 0x3F) | 0x100
+  x = ((b2 & 0xF0) >> 4) | ((b1 & 0x03) << 4)
+  y = ((b2 & 0x0F) << 2) | ((b3 & 0xC0) >> 6)
+  size = 0  // No size parameter
+```
+
+#### Type 3: Rare Objects (ID 0xF00-0xFFF)
+```
+Indicator: b3 >= 0xF8
+
+Byte format: xxxxxxii | yyyyyyii | 11111iii
+             b1         b2         b3
+
+Decoding:
+  id = (b3 << 4) | 0x80 | ((b2 & 0x03) << 2) | (b1 & 0x03)
+  x = (b1 & 0xFC) >> 2
+  y = (b2 & 0xFC) >> 2
+  size = ((b1 & 0x03) << 2) | (b2 & 0x03)
+```
+
+### Object Categories
+
+| Type | ID Range | Examples |
+|------|----------|----------|
+| Type 1 | 0x00-0xFF | Walls, floors, decorations |
+| Type 2 | 0x100-0x1FF | Corners, stairs, furniture |
+| Type 3 | 0xF00-0xFFF | Chests, pipes, special objects |

+
+### INCOMPLETE: BothBG Routines (4 locations)
+
+These routines should draw to BOTH BG1 and BG2 but currently only call single-layer version:
+
+```cpp
+// Line 375-381: DrawRightwards2x4spaced4_1to16_BothBG
+// Line 437-442: DrawDiagonalAcute_1to16_BothBG
+// Line 444-449: DrawDiagonalGrave_1to16_BothBG
+// Line 755-761: DrawDownwards4x2_1to16_BothBG
+
+// Current (WRONG):
+void DrawRightwards2x4spaced4_1to16_BothBG(
+    const RoomObject& obj, gfx::BackgroundBuffer& bg,  // Only 1 buffer!
+    std::span<const gfx::TileInfo> tiles) {
+  // Just calls single-layer version - misses BG2
+  DrawRightwards2x4spaced4_1to16(obj, bg, tiles);
+}
+
+// Should be:
+void DrawRightwards2x4spaced4_1to16_BothBG(
+    const RoomObject& obj,
+    gfx::BackgroundBuffer& bg1,  // Both buffers
+    gfx::BackgroundBuffer& bg2,
+    std::span<const gfx::TileInfo> tiles) {
+  DrawRightwards2x4spaced4_1to16(obj, bg1, tiles);
+  DrawRightwards2x4spaced4_1to16(obj, bg2, tiles);
+}
+```
+
+### UNCLEAR: Diagonal Routines
+
+```cpp
+// Lines 401-417, 419-435
+// Issues:
+// - Hardcoded +6 and 5 iterations (why?)
+// - Coordinate formula may produce negative Y
+// - Only uses 4 tiles from larger span
+// - No bounds checking
+
+for (int s = 0; s < size + 6; s++) {  // Why +6?
+  for (int i = 0; i < 5; i++) {       // Why 5?
+    WriteTile8(bg, obj.x_ + s, obj.y_ + (i - s), tiles[i % 4]);
+    // ^^ (i - s) can be negative when s > i
+  }
+}
+```
+
+---
+
+## 5. Tile Rendering Pipeline
+
+### WriteTile8() - Tile to Pixel Conversion
+```cpp
+// object_drawer.cc lines 863-883
+void WriteTile8(gfx::BackgroundBuffer& bg, int tile_x, int tile_y,
+                const gfx::TileInfo& tile_info) {
+  // tile coords → pixel coords: tile_x * 8, tile_y * 8
+  DrawTileToBitmap(bitmap, tile_info, tile_x * 8, tile_y * 8, room_gfx_buffer_);
+}
+```
+
+### DrawTileToBitmap() - Pixel Rendering
+```cpp
+// object_drawer.cc lines 890-970
+// Key steps:
+// 1. Graphics sheet lookup: tile_info.id_ → (sheet_x, sheet_y)
+// 2. Palette offset: (palette & 0x0F) * 8
+// 3. Per-pixel with mirroring support
+// 4. Color 0 = transparent (skipped)
+
+int tile_sheet_x = (tile_info.id_ % 16) * 8;   // 0-127 pixels
+int tile_sheet_y = (tile_info.id_ / 16) * 8;   // 0-127 pixels
+uint8_t palette_offset = (tile_info.palette_ & 0x0F) * 8;
+
+for (int py = 0; py < 8; py++) {
+  for (int px = 0; px < 8; px++) {
+    int src_x = tile_info.horizontal_mirror_ ? (7 - px) : px;
+    int src_y = tile_info.vertical_mirror_ ? (7 - py) : py;
+    // Read pixel, apply palette, write to bitmap
+  }
+}
+```
+
+### Palette Application (CRITICAL)
+```cpp
+// object_drawer.cc lines 71-115
+// Palette must be applied AFTER drawing, BEFORE SDL sync
+
+// 1. Draw all objects (writes palette indices 0-255)
+for (auto& obj : objects) {
+  DrawObject(obj, bg1, bg2, palette_group);
+}
+
+// 2. Apply dungeon palette to convert indices → RGB
+bg1_bmp.SetPalette(dungeon_palette);
+bg2_bmp.SetPalette(dungeon_palette);
+
+// 3. Sync to SDL surfaces
+SDL_LockSurface(bg1_bmp.surface());
+memcpy(bg1_bmp.surface()->pixels, bg1_bmp.mutable_data().data(), ...);
+SDL_UnlockSurface(bg1_bmp.surface());

+# Initiative: Test Suite Slimdown & Gating
+
+## Goal
+Reduce test bloat, keep high-signal coverage, and gate optional AI/ROM/bench suites. Deliver lean default CI (stable + smokes) with optional nightly heavy suites.
+
+## Scope & Owners
+- **test-infrastructure-expert**: Owns harness/labels/CTests; flake triage and duplication removal.
+- **ai-infra-architect**: Owns AI/experimental/ROM gating logic (skip when keys/runtime missing).
+- **docs-janitor**: Updates docs (test/README, CI docs) for default vs optional suites.
+- **backend-infra-engineer**: CI pipeline changes (default vs nightly matrices).
+- **imgui-frontend-engineer**: Rendering/UI test pruning, keep one rendering suite.
+- **snes-emulator-expert**: Consult if emulator tests are affected.
+- **GEMINI_AUTOM**: Quick TODO fixes in tests (small, low-risk).
+
+## Deliverables
+1) Default test set: stable + e2e smokes (framework, dungeon editor, canvas); one rendering suite only.
+2) Optional suites gated: ROM-dependent, AI experimental, benchmarks (off by default); skip cleanly when missing ROM/keys.
+3) Prune duplicates: drop legacy rendering/e2e duplicates and legacy dungeon_editor_test if v2 covers it.
+4) Docs: Updated test/README and CI docs with clear run commands and labels.
+5) CI: PR/commit matrix runs lean set; nightly matrix runs optional suites.
+
+## Tasks
+- Inventory and prune
+  - Keep integration/dungeon_object_rendering_tests_new.cc; drop older rendering integration + e2e variants.
+  - Drop/retire dungeon_editor_test.cc (v1) if v2 covers current UI.
+- Gating
+  - Ensure yaze_test_experimental and rom_dependent suites are off by default; add labels/presets for nightly.
+  - AI tests skip gracefully if AI runtime/key missing.
+- CI changes
+  - PR: stable + smokes only; Nightly: add ROM + AI + bench.
+- Docs
+  - Update test/README.md and CI docs to reflect default vs optional suites and commands/labels.
+- Quick fixes
+  - Triage TODOs: compression header off-by-one, test_editor window/controller handling; fix or mark skipped with reason.
+
+## Success Criteria
+- CTest/CI default runs execute only stable + smokes and one rendering suite.
+- Optional suites runnable via label/preset; fail early if pre-reqs missing.
+- Documentation matches actual behavior.
+- No regressions in core stable tests.
+
+## Coordination
+- Post progress/hand-offs to coordination-board.md.
+- Use designated agent IDs above when claiming work.

+
+## 2. Completed Work (Gemini's Previous Session)
+
+### ASM Version Check Standardization
+- Replaced raw `asm_version >= 3` with `OverworldVersionHelper::SupportsAreaEnum()`
+- Fixed critical bug: vanilla ROMs (0xFF) incorrectly treated as v3+
+- Applied consistently across: `overworld.cc`, `overworld_item.cc`, `overworld_map.cc`
+
+### Tile16Editor Texture Queueing
+- Fixed `tile16_editor.cc` lines 37-38, 44-45, 56-57
+- Pattern: `QueueTextureCommand()` instead of `RenderBitmap()` during init
+
+### Test Infrastructure
+- Created `test/unit/zelda3/overworld_regression_test.cc`
+- Tests `OverworldVersionHelper` logic (passing)
+
+---
+
+## 3. Remaining Work Checklist
+
+### P0 - Must Complete
+
+#### Texture Queueing TODOs in overworld_editor.cc
+6 locations still use inline rendering instead of deferred queueing:
+
+| Line | Current Code | Fix Pattern |
+|------|--------------|-------------|
+| 1392 | `// TODO: Queue texture` | Use `QueueTextureCommand()` |
+| 1397 | `// TODO: Queue texture` | Use `QueueTextureCommand()` |
+| 1740 | `// TODO: Queue texture` | Use `QueueTextureCommand()` |
+| 1809 | `// TODO: Queue texture` | Use `QueueTextureCommand()` |
+| 1819 | `// TODO: Queue texture` | Use `QueueTextureCommand()` |
+| 1962 | `// TODO: Queue texture` | Use `QueueTextureCommand()` |
+
+**Pattern to follow** (from tile16_editor.cc):
+```cpp
+// BEFORE (blocking)
+Renderer::Get().RenderBitmap(&some_bitmap_);
+
+// AFTER (non-blocking)
+gfx::Arena::Get().QueueTextureCommand(gfx::TextureCommand{
+    .operation = gfx::TextureOperation::kCreate,
+    .bitmap = &some_bitmap_,
+    .priority = gfx::TexturePriority::kHigh
+});
+```
+
+#### Entity Deletion Pattern (entity.cc:319) - WORKING CORRECTLY
+- **Note:** The TODO comment is misleading. The `deleted` flag pattern IS CORRECT for ROM editors
+- Entities live at fixed ROM offsets, so marking `deleted = true` is the proper approach
+- Renderer correctly skips deleted entities (see `overworld_entity_renderer.cc`)
+- `entity_operations.cc` reuses deleted slots when creating new entities
+- **No fix needed** - just a cleanup of the misleading TODO comment
+
+### P1 - Should Complete
+
+#### Tile16Editor Undo/Redo - ALREADY COMPLETE
+- Location: `tile16_editor.cc:1681-1760`
+- `SaveUndoState()` called before all edit operations
+- `Undo()` and `Redo()` fully implemented with `absl::Status` returns
+- Ctrl+Z/Ctrl+Y handling at lines 224-231
+- Stack management with `kMaxUndoStates_` limit
+- **No additional work needed**
+
+#### Overworld Regression Test Completion
+- Location: `test/unit/zelda3/overworld_regression_test.cc`
+- Current: Only tests version helper
+- Need: Add more comprehensive mock ROM data
+
+### P2 - Stretch Goals
+
+#### Dungeon Downwards Draw Routines
+- Location: `src/zelda3/dungeon/object_drawer.cc` lines 160-185
+- Missing implementations marked with stubs
+- Need: Implement based on game ROM patterns
+
+#### E2E Cinematic Tests
+- Design doc: `docs/internal/testing/dungeon-gui-test-design.md`
+- Framework: ImGuiTestEngine integration ready
+- Need: Screenshot capture, visual verification
+
+---
+
+## 4. Key Patterns
+
+### Bitmap/Surface Synchronization
+```cpp
+// CORRECT: Use set_data() for bulk replacement
+bitmap.set_data(new_data);  // Syncs both data_ and surface_->pixels
+
+// WRONG: Direct assignment breaks sync
+bitmap.mutable_data() = new_data;  // NEVER DO THIS
+```
+
+### Graphics Refresh Order
+```cpp
+// 1. Update model
+map.SetProperty(new_value);
+
+// 2. Reload from ROM
+map.LoadAreaGraphics();
+
+// 3. Force render
+Renderer::Get().RenderBitmap(&map_bitmap_);  // Immediate
+// OR
+gfx::Arena::Get().QueueTextureCommand(...);  // Deferred (preferred)
+```
+
+### Version Helper Usage
+```cpp
+#include "zelda3/overworld/overworld_version_helper.h"
+
+auto version = OverworldVersionHelper::GetVersion(*rom_);
+
+// Feature gates
+if (OverworldVersionHelper::SupportsAreaEnum(version)) {
+  // v3+ only features
+}
+if (OverworldVersionHelper::SupportsExpandedSpace(version)) {
+  // v1+ features
+}
+```
+
+### Entity Rendering Colors (0.85f alpha)
+```cpp

+# Z3ED CLI & Agent API Enhancement Design
+
+## Executive Summary
+
+This document outlines comprehensive enhancements to the z3ed CLI and agent APIs to significantly improve AI agent interaction with YAZE. The design focuses on enabling better automation, testing, and feature development through a robust command interface, programmatic editor access, and enhanced collaboration features.
+
+## Current Architecture Analysis
+
+### Existing Components
+- **CLI Framework**: ModernCLI with CommandRegistry pattern
+- **Command Handlers**: 70+ specialized handlers (hex, palette, sprite, music, dialogue, dungeon, overworld, gui, emulator)
+- **Canvas Automation API**: Programmatic interface for tile operations, selection, and view control
+- **Network Client**: WebSocket/HTTP fallback for collaborative editing
+- **HTTP API**: REST endpoints for health, models, and basic operations
+- **Model Integration**: Ollama and Gemini support through ModelRegistry
+
+### Key Strengths
+- Clean command handler abstraction with consistent execution pattern
+- Canvas automation already supports tile operations and coordinate conversion
+- Network infrastructure in place for collaboration
+- Extensible model registry for multiple AI providers
+
+### Gaps to Address
+- Limited ROM direct manipulation commands
+- No session persistence or REPL mode
+- Minimal test generation capabilities
+- Limited agent coordination features
+- No batch operation support for complex workflows
+- Missing introspection and discovery APIs
+
+## 1. Z3ED CLI Enhancements
+
+### 1.1 ROM Operations Commands
+
+```bash
+# Direct ROM manipulation
+z3ed rom read --address <hex> [--length <bytes>] [--format hex|ascii|binary]
+z3ed rom write --address <hex> --data <hex_string> [--verify]
+z3ed rom validate [--checksums] [--headers] [--regions]
+z3ed rom diff --base <rom1> --compare <rom2> [--output patch]
+z3ed rom patch --input <rom> --patch <ips|bps> --output <patched_rom>
+z3ed rom export --region <name> --start <hex> --end <hex> --output <file>
+z3ed rom import --region <name> --address <hex> --input <file>
+
+# ROM state management
+z3ed rom snapshot --name <snapshot_name> [--compress]
+z3ed rom restore --snapshot <name> [--verify]
+z3ed rom list-snapshots [--details]
+z3ed rom compare-snapshot --current --snapshot <name>
+```
+
+#### Implementation Details
+```cpp
+class RomReadCommandHandler : public CommandHandler {
+protected:
+  absl::Status ValidateArgs(const ArgumentParser& parser) override {
+    RETURN_IF_ERROR(parser.RequireArgs({"address"}));
+    if (auto len = parser.GetInt("length")) {
+      if (*len <= 0 || *len > 0x10000) {
+        return absl::InvalidArgumentError("Length must be 1-65536 bytes");
+      }
+    }
+    return absl::OkStatus();
+  }
+
+  absl::Status Execute(Rom* rom, const ArgumentParser& parser,
+                      OutputFormatter& formatter) override {
+    uint32_t address = parser.GetHex("address").value();
+    int length = parser.GetInt("length").value_or(16);
+    std::string format = parser.GetString("format").value_or("hex");
+
+    std::vector<uint8_t> data;
+    for (int i = 0; i < length; i++) {
+      data.push_back(rom->ReadByte(address + i));
+    }
+
+    formatter.AddField("address", absl::StrFormat("0x%06X", address));
+    formatter.AddField("data", FormatData(data, format));
+    return absl::OkStatus();
+  }
+};

+# Agent Coordination & Documentation Improvement Plan
+
+## Findings
+1. **Persona Inconsistency**: `coordination-board.md` uses a mix of legacy IDs (`CLAUDE_AIINF`) and new canonical IDs (`ai-infra-architect`).
+2. **Tool Underutilization**: The protocol in `AGENTS.md` relies entirely on manual Markdown edits, ignoring the built-in `z3ed agent` CLI tools (todo, handoff) described in `agent-architecture.md`.
+3. **Fragmented Docs**: There is no central entry point (`README.md`) for agents entering the directory.
+4. **Undefined Systems**: `claude-gemini-collaboration.md` references a "challenge system" and "leaderboard" that do not exist.
+
+## Proposed Actions
+
+### 1. Update `AGENTS.md` (The Protocol)
+*   **Mandate CLI Tools**: Update the "Quick tasks" and "Substantial work" sections to recommend using `z3ed agent todo` for personal task tracking.
+*   **Clarify Handoffs**: Explicitly mention using `z3ed agent handoff` for transferring context, with the Markdown board used for *public signaling*.
+*   **Strict Persona Usage**: Remove "Legacy aliases" mapping and simply link to `personas.md` as the source of truth.
+
+### 2. Cleanup `coordination-board.md` (The Board)
+*   **Header Update**: Add a bold warning to use only IDs from `personas.md`.
+*   **Retroactive Fix**: Update recent active entries to use the correct new IDs (e.g., convert `CLAUDE_AIINF` -> `ai-infra-architect` where appropriate).
+
+### 3. Create `docs/internal/agents/README.md` (The Hub)
+*   Create a simple index file that links to:
+    *   **Protocol**: `AGENTS.md`
+    *   **Roles**: `personas.md`
+    *   **Status**: `coordination-board.md`
+    *   **Tools**: `agent-architecture.md`
+*   Provide a 3-step "Start Here" guide for new agents.
+
+### 4. Deprecate `claude-gemini-collaboration.md`
+*   Rename to `docs/internal/agents/archive/collaboration-concept-legacy.md` or remove the "Challenge System" sections if the file is still valuable for its architectural definitions.
+*   *Recommendation*: If the "Architecture vs. Automation" split is still relevant, update the file to use `backend-infra-engineer` (Architecture) vs `GEMINI_AUTOM` (Automation) instead of "Claude vs Gemini".
+
+## Execution Order
+1.  Create `docs/internal/agents/README.md`.
+2.  Update `AGENTS.md`.
+3.  Clean up `coordination-board.md`.
+4.  Refactor `claude-gemini-collaboration.md`.

+# Documentation Cleanup Summary - November 2025
+
+**Date:** 2025-11-24
+**Action:** Cleanup of speculative planning documents and AI-generated bloat from `/docs/internal/plans/`
+**Rationale:** Planning documents should live in GitHub issues and coordination board, not as static markdown. Only actionable, actively-tracked plans belong in the codebase.
+
+## Files Deleted (Pure AI-Generated Bloat)
+
+These files were entirely speculative with no corresponding implementation:
+
+1. **asm-debug-prompt-engineering.md** (45KB)
+   - Extensive prompt templates for 65816 debugging
+   - No evidence of integration or use
+   - Classified as AI-generated reference material
+
+2. **ai-assisted-development-plan.md** (17KB)
+   - Workflow proposal for AI-assisted development
+   - All features marked "Active" with "Next Review" dates but never implemented
+   - Generic architecture diagrams with no corresponding code
+
+3. **app-dev-agent-tools.md** (21KB)
+   - 824 lines specifying 16 agent tools (build, code analysis, debug, editor integration)
+   - All tools in Phase 1-3 (theoretical)
+   - No implementation in codebase or recent commits
+
+4. **EDITOR_ROADMAPS_2025-11.md** (25KB)
+   - Multi-agent analysis document referencing "imgui-frontend-engineer" agent analysis
+   - Generic roadmap format with estimated effort hours
+   - Duplicate content with dungeon_editor_ui_refactor.md
+
+5. **message_system_improvement_plan.md** (2KB)
+   - Duplicate of sections in message_editor_implementation_roadmap.md
+   - Generic feature wishlist (JSON export, translation workspace, search & replace)
+   - No distinct value
+
+6. **graphics_system_improvement_plan.md** (2.8KB)
+   - Feature wishlist (unified editor, palette management, sprite assembly)
+   - No concrete deliverables or implementation plan
+   - Superseded by architecture documentation
+
+7. **ui_modernization.md** (3.3KB)
+   - Describes patterns already documented in CLAUDE.md
+   - Marked "Active" but content is obsolete (already implemented)
+   - Redundant with existing guidelines
+
+## Files Archived (Partially Implemented / Historical Reference)
+
+These files have some value as reference but are not actively tracked work:
+
+1. **emulator-debug-api-design.md** → `archive/plans-2025-11/`
+   - Design document for emulator debugging API
+   - Some features implemented (breakpoints, memory inspection)
+   - Watchpoints and symbol loading still planned but deprioritized
+   - Value: Technical reference for future work
+
+2. **message_editor_implementation_roadmap.md** → `archive/plans-2025-11/`
+   - References actual code (MessageData, MessagePreview classes)
+   - Documents what's completed vs. what's missing (JSON import/export)
+   - Some ongoing development but should be tracked in coordination board
+   - Value: Implementation reference
+
+3. **hex_editor_enhancements.md** → `archive/plans-2025-11/`
+   - Phase 1 (Data Inspector) concept defined
+   - Phases 2-4 unimplemented
+   - Better tracked as GitHub issue than static plan
+   - Value: Technical spike reference
+
+4. **dungeon_editor_ui_refactor.md** → `archive/plans-2025-11/`
+   - Actually referenced in git commit acab491a1f (component was removed)
+   - Concrete refactoring steps with clear deliverables
+   - Now completed/obsolete
+   - Value: Historical record of refactoring
+
+## Files Retained (Actively Tracked)
+
+1. **web_port_strategy.md**
+   - Strategic milestone document for WASM port
+   - Multiple recent commits show active ongoing work (52b1a99, 56e05bf, 206e926, etc.)
+   - Clear milestones with deliverables
+   - Actively referenced in CI/build processes
+   - Status: KEEP - actively developed feature
+
+2. **ai-infra-improvements.md**
+   - Structured phase-based plan (gRPC server, emulator RPCs, breakpoints, symbols)
+   - More specific than other plans with concrete files to modify
+   - Tracks infrastructure gaps with file references
+   - Status: KEEP - tracks ongoing infrastructure work
+
+3. **README.md**
+   - Directory governance and guidelines
+   - Actively enforces plan organization standards
+   - Status: KEEP - essential for directory management
+
+## Rationale for This Cleanup
+
+### Problem
+- 14 planning files (400KB) in `/docs/internal/plans/`
+- Most marked "Active" with forward-looking dates (Nov 25 → Dec 2)
+- Little correlation with actual work in recent commits
+- Directory becoming a repository of speculative AI-generated content
+
+### Solution
+- Keep only plans with active ongoing work (2 files)
+- Archive reference documents with partial implementation (4 files)
+- Delete pure speculation and AI-generated bloat (7 files)
+- Directory size reduced from 400KB to 13KB at root level
+
+### Principle
+**Planning belongs in GitHub issues and coordination board, not in markdown files.**
+
+Static plan documents should only exist for:
+1. Strategic initiatives (like WASM web port) with active commits
+2. Infrastructure work with concrete phases and file references
+3. Historical reference after completion
+
+Speculative planning should use:
+- GitHub Discussions for RFCs
+- Issues with labels for feature requests
+- Coordination board for multi-agent work tracking

+# Dungeon Editor UI Refactor Plan
+
+## 1. Overview
+The Dungeon Editor currently uses a primitive "colored square" representation for objects in the object selector, despite having a full-fidelity rendering component (`DungeonObjectSelector`) available. This plan outlines the refactoring steps to integrate the game-accurate object browser into the main `ObjectEditorCard`, improving UX and eliminating code duplication.
+
+## 2. Current State Analysis
+- **`ObjectEditorCard` (Active UI):** Reimplements object selection logic in `DrawObjectSelector()`. Renders objects as simple colored rectangles (`DrawObjectPreviewIcon`).
+- **`DungeonObjectSelector` (Component):** Contains `DrawObjectAssetBrowser()`, which uses `ObjectDrawer` to render actual tile graphics. This component is instantiated as a member `object_selector_` in `ObjectEditorCard` but is effectively unused.
+- **`DungeonEditorV2`:** Instantiates a separate, unused `DungeonObjectSelector` (`object_selector_`), adding to the confusion.
+
+## 3. Implementation Plan
+
+### Phase 1: Component Preparation
+1.  **Expose UI Method:** Ensure `DungeonObjectSelector::DrawObjectAssetBrowser()` is public or accessible to `ObjectEditorCard`.
+2.  **State Synchronization:** Ensure `DungeonObjectSelector` has access to the same `Rom` and `PaletteGroup` data as `ObjectEditorCard` so it can render correctly.
+
+### Phase 2: Refactor ObjectEditorCard
+1.  **Delegate Rendering:** Replace the body of `ObjectEditorCard::DrawObjectSelector()` with a call to `object_selector_.DrawObjectAssetBrowser()`.
+2.  **Callback Wiring:**
+    *   In `ObjectEditorCard::Initialize` (or constructor), set up the callback for `object_selector_`.
+    *   When an object is selected in `object_selector_`, it should update `ObjectEditorCard::preview_object_` and `canvas_viewer_`.
+    *   Current logic:
+        ```cpp
+        object_selector_.SetObjectSelectedCallback([this](const zelda3::RoomObject& obj) {
+            this->preview_object_ = obj;
+            this->has_preview_object_ = true;
+            this->canvas_viewer_->SetPreviewObject(obj);
+            this->interaction_mode_ = InteractionMode::Place;
+        });
+        ```
+3.  **Cleanup:** Remove private helper `DrawObjectPreviewIcon` and the old loop logic in `ObjectEditorCard`.
+
+### Phase 3: Cleanup DungeonEditorV2
+1.  **Remove Redundancy:** Remove the top-level `DungeonObjectSelector object_selector_` from `DungeonEditorV2`. The one inside `ObjectEditorCard` is sufficient.
+2.  **Verify Initialization:** Ensure `DungeonEditorV2` correctly initializes `ObjectEditorCard` with the necessary dependencies.
+
+## 4. Verification
+1.  **Build:** Compile `yaze`.
+2.  **Test:** Open Dungeon Editor -> Object Editor tab.
+3.  **Expectation:** The object list should now show actual graphics (walls, chests, pots) instead of colored squares.
+4.  **Interaction:** Clicking an object should correctly load it into the cursor for placement.
+
+## 5. Dependencies
+- `src/app/editor/dungeon/object_editor_card.cc`
+- `src/app/editor/dungeon/object_editor_card.h`
+- `src/app/editor/dungeon/dungeon_object_selector.cc`

+
+## Phase 1 (MVP) Features
+
+### 1. Execution Control API
+
+```cpp
+// Tool Dispatcher Commands
+enum class EmulatorDebugTool {
+  // Basic execution
+  kDebugRun,           // Run until breakpoint or pause
+  kDebugStep,          // Single instruction step
+  kDebugStepOver,      // Step over JSR/JSL calls
+  kDebugStepOut,       // Step out of current subroutine
+  kDebugPause,         // Pause execution
+  kDebugReset,         // Reset to power-on state
+
+  // Breakpoint management
+  kDebugSetBreak,      // Set execution breakpoint
+  kDebugClearBreak,    // Clear breakpoint by ID
+  kDebugListBreaks,    // List all breakpoints
+  kDebugToggleBreak,   // Enable/disable breakpoint
+};
+```
+
+#### Example Tool Call Structure:
+```cpp
+struct DebugStepRequest {
+  enum StepType {
+    SINGLE,      // One instruction
+    OVER,        // Step over calls
+    OUT,         // Step out of routine
+    TO_ADDRESS   // Run to specific address
+  };
+
+  StepType type;
+  uint32_t target_address;  // For TO_ADDRESS
+  uint32_t max_steps;       // Timeout protection
+};
+
+struct DebugStepResponse {
+  bool success;
+  uint32_t pc;              // New program counter
+  uint32_t instruction_count;
+  DisassembledInstruction current_instruction;
+  std::vector<std::string> call_stack;
+  std::string message;
+};
+```
+
+### 2. Memory Inspection API
+
+```cpp
+enum class MemoryDebugTool {
+  kMemoryRead,         // Read memory region
+  kMemoryWrite,        // Write memory (for patching)
+  kMemoryWatch,        // Set memory watchpoint
+  kMemoryCompare,      // Compare two memory regions
+  kMemorySearch,       // Search for byte pattern
+  kMemorySnapshot,     // Save memory state
+  kMemoryDiff,         // Diff against snapshot
+};
+```
+
+#### Memory Region Types:
+```cpp
+enum class MemoryRegion {
+  WRAM,      // Work RAM ($7E0000-$7FFFFF)

+# Plan: Hex Editor Enhancements (Inspired by ImHex)
+
+**Status:** Active  
+**Owner (Agent ID):** imgui-frontend-engineer  
+**Last Updated:** 2025-11-25  
+**Next Review:** 2025-12-02  
+**Coordination Board Entry:** link when claimed
+
+This document outlines the roadmap for enhancing the `yaze` Memory/Hex Editor to provide robust analysis tools similar to ImHex.
+
+## Phase 1: Data Inspector (High Priority)
+
+**Goal:** Provide immediate context for the selected byte(s) in the Hex Editor without mental math.
+
+**Implementation Steps:**
+1.  **Create `DataInspector` Component:**
+    *   A standalone ImGui widget (`src/app/editor/code/data_inspector.h/cc`).
+    *   Accepts a `const uint8_t* data_ptr` and `size_t max_len`.
+2.  **Standard Types:**
+    *   Decode and display Little Endian values:
+        *   `int8_t` / `uint8_t`
+        *   `int16_t` / `uint16_t`
+        *   `int24_t` / `uint24_t` (Common SNES pointers)
+        *   `int32_t` / `uint32_t`
+    *   Display Binary representation (`00001111`).
+3.  **SNES-Specific Types (The "Yaze" Value):**
+    *   **SNES LoROM Address:** Convert the physical offset to `$BB:AAAA` format.
+    *   **RGB555 Color:** Interpret 2 bytes as `0bbbbbgggggrrrrr`. Show a colored rectangle preview.
+    *   **Tile Attribute:** Interpret byte as `vhopppcc` (Vertical/Horizontal flip, Priority, Palette, Tile High bit).
+4.  **Integration:**
+    *   Modify `MemoryEditorWithDiffChecker` to instantiate and render `DataInspector` in a sidebar or child window next to the main hex grid.
+    *   Hook into the hex editor's "Selection Changed" event (or poll selection state) to update the Inspector.
+
+## Phase 2: Entropy Navigation (Navigation)
+
+**Goal:** Visualize the ROM's structure to quickly find free space, graphics, or code.
+
+**Implementation Steps:**
+1.  **Entropy Calculator:**
+    *   Create a utility to calculate Shannon entropy for blocks of data (e.g., 256-byte chunks).
+    *   Run this calculation in a background thread when a ROM is loaded to generate an `EntropyMap`.
+2.  **Minimap Widget:**
+    *   Render a thin vertical bar next to the hex scrollbar.
+    *   Map the file offset to vertical pixels.
+    *   **Color Coding:**
+        *   **Black:** Zeroes (`0x00` fill).
+        *   **Dark Grey:** `0xFF` fill (common flash erase value).
+        *   **Blue:** Low entropy (Text, Tables).
+        *   **Red:** High entropy (Compressed Graphics, Code).
+3.  **Interaction:**
+    *   Clicking the minimap jumps the Hex Editor to that offset.
+
+## Phase 3: Structure Templates (Advanced Analysis)
+
+**Goal:** Define and visualize complex data structures on top of the raw hex.
+
+**Implementation Steps:**
+1.  **Template Definition System:**
+    *   Define a C++-based schema builder (e.g., `StructBuilder("Header").AddString("Title", 21).AddByte("MapMode")...`).
+2.  **Visualizer:**
+    *   Render these structures as a tree view (ImGui TreeNodes).
+    *   When a tree node is hovered, highlight the corresponding bytes in the Hex Editor grid.
+3.  **Standard Templates:**
+    *   Implement templates for known ALTTP structures: `SNES Header`, `Dungeon Header`, `Sprite Properties`.
+
+## Phase 4: Disassembly Integration
+
+**Goal:** Seamless transition between data viewing and code analysis.
+
+**Implementation Steps:**
+1.  **Context Menu:** Add "Disassemble Here" to the Hex Editor right-click menu.
+2.  **Disassembly View:**
+    *   Invoke the `disassembler` (already present in `app/emu/debug`) on the selected range.
+    *   Display the output in a popup or switch to the Assembly Editor.
+
+---
+
+## Initial Work Item: Data Inspector
+
+We will begin with Phase 1. This requires creating the `DataInspector` class and hooking it into `MemoryEditorWithDiffChecker`.

+# Message Editor Implementation Roadmap
+
+**Status**: Active Development  
+**Owner (Agent ID)**: imgui-frontend-engineer  
+**Last Updated**: 2025-11-25  
+**Next Review**: 2025-12-02  
+**Coordination Board Entry**: link when claimed
+**Related Docs**:
+- `docs/internal/architecture/message_system.md` (Gemini's architecture vision)
+- `docs/internal/plans/message_system_improvement_plan.md` (Gemini's feature proposals)
+
+---
+
+## Executive Summary
+
+This roadmap bridges Gemini's architectural vision with practical implementation steps for completing the Message Editor. The current implementation has the **core foundation** in place (message parsing, dictionary system, preview rendering) but lacks several key features proposed in Gemini's plan, particularly around **JSON import/export**, **translation workflows**, and **theme integration**.
+
+---
+
+## Current State Analysis
+
+### What's Working (Completed Features)
+
+#### Core Data Layer ✅
+- **MessageData**: Full implementation with raw/parsed representations
+- **DictionaryEntry**: Compression system with dictionary optimization
+- **TextElement**: Command and special character parsing
+- **Character Encoding**: Complete CharEncoder table (0x00-0x66)
+- **ROM Reading**: `ReadAllTextData()` successfully loads all 396 messages
+- **ROM Writing**: `Save()` handles two-bank text data with overflow detection
+
+#### Message Preview System ✅
+- **MessagePreview**: Live rendering of messages as they appear in-game
+- **Font Graphics**: 2BPP font tiles loaded and displayed at 0x70000
+- **Character Widths**: Proportional font support via width table at 0x74ADF
+- **Preview Bitmap**: Real-time message rendering with proper palette support
+
+#### Editor UI ✅
+- **Card System**: Four dockable cards (Message List, Editor, Font Atlas, Dictionary)
+- **Message List**: Table view with ID, contents, and address columns
+- **Text Editor**: Multiline input with live preview updates
+- **Command Insertion**: Buttons to insert text commands and special characters
+- **Dictionary Display**: Read-only view of all 97 dictionary entries
+- **Expanded Messages**: Basic support for loading external message bins
+
+#### Testing Coverage ✅
+- **Unit Tests**: 20+ tests covering parsing, encoding, dictionary optimization
+- **Integration Tests**: ROM-dependent tests verify actual game data
+- **Command Parsing**: Regression tests for argument handling bugs
+
+#### CLI Integration ✅
+- **Message List**: `z3ed message list --format json --range 0-100`
+- **Message Read**: `z3ed message read --id 5 --format json`
+- **Message Search**: `z3ed message search --query "Link"`
+- **Message Stats**: `z3ed message stats --format json`
+
+### What's Missing (Gaps vs. Gemini's Vision)
+
+#### 1. JSON Import/Export ❌ (HIGH PRIORITY)
+**Status**: Not implemented
+**Gemini's Vision**:
+```json
+[
+  {
+    "id": 0,
+    "address": 917504,
+    "text": "[W:00][SPD:00]Welcome to [D:05]...",
+    "context": "Uncle dying in sewers"
+  }
+]
+```
+
+**Current Gap**:
+- No `SerializeMessages()` or `DeserializeMessages()` in `MessageData`
+- No UI for export/import operations
+- No context field for translator notes
+- CLI has JSON output but not JSON input
+
+**Impact**: Cannot version control text, cannot use external editors, cannot collaborate with translators
+
+---
+
+#### 2. Translation Workspace ❌ (MEDIUM PRIORITY)
+**Status**: Not implemented
+**Gemini's Vision**: Side-by-side view with reference ROM/JSON and editable translation
+
+**Current Gap**:
+- No reference text display
+- No side-by-side layout
+- No translation progress tracking
+- No language-specific dictionary optimization
+
+**Impact**: Manual translation workflows are tedious and error-prone
+
+---
+
+#### 3. Search & Replace ⚠️ (PARTIAL)
+**Status**: Stub implementation exists
+**Gemini's Vision**: Regex support, batch replace across all messages
+
+**Current Implementation**:
+- `Find()` method exists in `MessageEditor` (lines 574-600)
+- Basic UI skeleton present (search input, case sensitivity toggle)
+- **Missing**: Replace functionality, regex support, "Find All", multi-message operations
+
+**Impact**: Global text edits require manual per-message changes
+
+---
+
+#### 4. Theme Integration ❌ (LOW PRIORITY - UI POLISH)
+**Status**: Not implemented
+**Current Issues**:
+- No hardcoded `ImVec4` colors found (GOOD!)
+- Not using `AgentUITheme` system for consistency
+- Missing semantic color names for message editor components
+
+**Impact**: Message Editor UI may not match rest of application theme
+
+---
+
+#### 5. Expanded ROM Support ⚠️ (PARTIAL)
+**Status**: Basic implementation exists
+**Gemini's Vision**: Repointing text blocks to expanded ROM space (Banks 10+), automatic bank switching
+
+**Current Implementation**:
+- Can load expanded message bins (lines 322-334)
+- Can save expanded messages (lines 497-508)
+- **Missing**: Repointing logic, bank management, automatic overflow handling
+
+**Impact**: Cannot support large translation projects that exceed vanilla space
+
+---
+
+#### 6. Scripting Integration ❌ (FUTURE)
+**Status**: Not planned
+**Gemini's Vision**: Lua/Python API for procedural text generation
+
+**Current Gap**: No scripting hooks in message system
+
+**Impact**: Low - nice-to-have for advanced users
+
+---
+
+## Architectural Decisions Required
+
+### Decision 1: JSON Schema Design
+**Question**: What fields should the JSON export include?
+
+**Proposal**:
+```json
+{
+  "version": "1.0",
+  "rom_name": "zelda3.sfc",
+  "messages": [
+    {
+      "id": 0,
+      "address": 917504,
+      "address_hex": "0xE0000",
+      "text": "[W:00][SPD:00]Welcome...",
+      "context": "Optional translator note",
+      "dictionary_optimized": true,
+      "expanded": false
+    }
+  ],
+  "dictionary": [
+    {
+      "id": 0,
+      "token": "[D:00]",
+      "contents": "the"
+    }
+  ]
+}
+```
+
+**Trade-offs**:
+- Verbose but human-readable
+- Includes metadata for validation
+- Context field for translator workflow
+
+**Status**: ✅ RECOMMENDED
+
+---
+
+### Decision 2: Translation Workspace Layout
+**Question**: How should reference vs. translation be displayed?
+
+**Option A**: Side-by-side split pane
+```
+┌────────────────┬────────────────┐
+│ Reference      │ Translation    │
+│ (English)      │ (Spanish)      │
+│ [Read-only]    │ [Editable]     │
+│                │                │
+│ Message 0:     │ Message 0:     │
+│ "Welcome to    │ "Bienvenido a  │
+│  Hyrule"       │  Hyrule"       │
+└────────────────┴────────────────┘
+```
+
+**Option B**: Top-bottom with context panel
+```
+┌────────────────────────────────┐
+│ Reference: "Welcome to Hyrule" │
+│ Context: Uncle's dying words   │
+├────────────────────────────────┤
+│ Translation:                   │
+│ [Editable text box]            │
+└────────────────────────────────┘
+```
+
+**Recommendation**: Option A for large screens, Option B for narrow windows
+
+**Status**: ⚠️ NEEDS USER FEEDBACK
+
+---
+
+### Decision 3: Dictionary Auto-Optimization
+**Question**: Should we auto-generate optimal dictionary for new languages?
+
+**Challenges**:
+- Dictionary optimization is NP-hard (longest common substring problem)
+- Need to preserve ROM space constraints (97 entries max)
+- Different languages have different common phrases

+## Test Strategy
+
+### Unit Tests
+**Location**: `test/unit/message_data_test.cc` (new file)
+```cpp
+TEST(MessageDataTest, SerializeToJson_BasicMessage) {
+  MessageData msg;
+  msg.ID = 0;
+  msg.Address = 0xE0000;
+  msg.RawString = "Hello World";
+  msg.context = "Test message";

+
+### Integration Tests
+**Location**: `test/integration/message_export_test.cc` (new file)
+```cpp
+TEST_F(MessageRomTest, ExportImport_RoundTrip) {
+  // Export all messages to JSON
+  std::string json_path = "/tmp/messages.json";
+  EXPECT_OK(ExportMessagesToJson(list_of_texts_, dictionary_, json_path));

+
+  // Verify identical
+  EXPECT_EQ(imported.value().size(), list_of_texts_.size());

+    EXPECT_EQ(imported.value()[i].RawString, list_of_texts_[i].RawString);
+  }
+}
+```
+
+### E2E Tests
+**Location**: `test/e2e/message_editor_workflow_test.cc` (new file)
+```cpp
+TEST_F(MessageEditorE2ETest, TranslationWorkflow) {
+  // Open translation workspace
+  EXPECT_OK(ClickButton("Translation Mode"));
+
+  // Load reference ROM
+  EXPECT_OK(OpenFileDialog("reference_rom.sfc"));

+
+## Dependencies & Risks
+
+### External Dependencies
+1. **nlohmann/json**: Already integrated via CPM ✅
+2. **ImGui Test Engine**: Available for E2E tests ✅
+3. **File Dialog**: `util::FileDialogWrapper` already exists ✅
+
+### Technical Risks
+
+#### Risk 1: JSON Schema Evolution
+**Impact**: Breaking changes to JSON format
+**Mitigation**:
+- Include version number in schema
+- Implement forward/backward compatibility
+- Provide migration tool for old exports
+
+#### Risk 2: Dictionary Auto-Optimization Complexity
+**Impact**: Algorithm may be too slow for real-time use
+**Mitigation**:
+- Run optimization in background thread
+- Provide progress indicator
+- Allow cancellation
+
+#### Risk 3: Large ROM Size with Expanded Messages
+**Impact**: May exceed bank boundaries
+**Mitigation**:
+- Implement repointing logic early (Phase 5)
+- Warn user when approaching limits
+- Suggest dictionary optimization
+
+---
+

+## Timeline Estimate
+
+| Phase | Duration | Effort (Dev Days) |
+|-------|----------|-------------------|
+| Phase 1: JSON Export/Import | 2 weeks | 6 days |
+| Phase 2: Translation Workspace | 3 weeks | 9 days |
+| Phase 3: Search & Replace | 1 week | 4 days |
+| Phase 4: UI Polish | 1 week | 2 days |
+| **Total** | **7 weeks** | **21 dev days** |
+
+**Note**: Timeline assumes single developer working full-time. Adjust for part-time work or team collaboration.
+
+---
+
+## Future Enhancements (Post-MVP)
+
+1. **Scripting API** (Gemini's vision)
+   - Expose MessageData to Lua/Python
+   - Allow procedural text generation
+   - Useful for randomizers
+
+2. **Cloud Translation Integration**
+   - Google Translate API for quick drafts
+   - DeepL API for quality translations
+   - Requires API key management
+
+3. **Collaborative Editing**
+   - Real-time multi-user translation
+   - Conflict resolution for concurrent edits
+   - Requires network infrastructure
+
+4. **ROM Patch Generation**
+   - Export as `.ips` or `.bps` patch files
+   - Useful for distribution without ROM sharing
+   - Requires patch generation library
+
+5. **Message Validation**
+   - Check for overlong messages (exceeds textbox width)
+   - Verify all messages have terminators
+   - Flag unused dictionary entries
+
+---
+
+## Open Questions
+
+1. **Q**: Should we support multiple translation languages simultaneously?
+   **A**: TBD - May require multi-ROM workspace UI
+
+2. **Q**: How should we handle custom dictionary entries for expanded ROMs?
+   **A**: TBD - Need research into ROM space allocation
+
+3. **Q**: Should translation progress be persisted?
+   **A**: TBD - Could store in `.yaze` project file
+
+4. **Q**: Do we need undo/redo for message editing?
+   **A**: TBD - ImGui InputTextMultiline has built-in undo, may be sufficient
+
+---
+
+## Conclusion
+
+The Message Editor has a **solid foundation** with core parsing, preview, and UI systems in place. The main gaps are **JSON export/import** (P0), **translation workspace** (P1), and **search/replace** (P2).
+
+**Recommended Next Steps**:
+1. Start with Phase 1 (JSON export/import) - this unblocks all translation workflows
+2. Get user feedback on translation workspace mockups before Phase 2
+3. Defer theme integration to Phase 4 - not blocking functionality
+
+**Estimated Effort**: ~7 weeks to MVP, ~21 dev days total.
+
+**Success Criteria**: Translator can export messages to JSON, edit in external tool, and re-import without data loss. Side-by-side translation workspace reduces manual comparison time by 50%.
