# Rogue 5.4.4 WebAssembly Port — Definition of Done

## Scope

### In Scope

- Complete Rust reimplementation of all Rogue 5.4.4 game systems compiled to `wasm32-unknown-unknown`
- Single-page HTML deliverable with embedded JS terminal renderer at `demo/rogue/rogue-wasm/www/index.html`
- Classic 80x24 ASCII terminal display with monospace font on dark background
- All player commands (movement, inventory, combat, meta)
- Full monster AI and daemon/fuse timing system
- Wizard mode: create objects, teleport, level skip, map reveal, identify, and all debug commands
- Deterministic seed support for reproducible games
- Save/load via browser localStorage
- Keyboard input handling in the browser

### Out of Scope

- Mobile/touch input
- Sound or music
- Graphical tiles or non-ASCII rendering
- Multiplayer or networking
- High-score server or cross-session leaderboards (local only)
- Accessibility features beyond what the original had
- Performance optimization beyond "runs smoothly at 60fps"
- Wizard password authentication (replaced by simpler browser-friendly mechanism)
- Score file encryption (`xcrypt.c` XOR cipher)
- Multi-user score isolation (UID-based)
- Signal handling (SIGINT/SIGTSTP/SIGUSR)
- Cross-compilation to native binary
- Pixel-perfect terminal rendering (cursor blinking, terminal escape fidelity)
- Original save file format compatibility

### Assumptions

1. User has Rust stable, `cargo`, `rustc`, and `wasm-pack` installed
2. Deliverable served locally (e.g., `python -m http.server`)
3. Original C source at `demo/rogue/original-rogue/` is authoritative reference
4. Browser target: modern evergreen browsers (Chrome, Firefox, Safari, Edge -- latest two versions)
5. Wizard mode enabled via JS API call, URL parameter, or equivalent browser-friendly mechanism

### Overall

1. **At least one scenario tests the deliverable in its delivery form**: IT-7 loads the HTML deliverable in a browser and verifies it renders and accepts input. IT-1 verifies the WASM build succeeds and the HTML file exists and references the module.

2. **Every user-facing message from the inventory is triggered and validated by at least one scenario**: All 196 message surfaces (MSG-1 through MSG-196) are mapped to at least one IT scenario. MSG-1 through MSG-4 (core display) are covered by IT-6 and IT-7. MSG-5 through MSG-14 (movement/hunger) by IT-6. MSG-15 through MSG-36 (combat/monsters) by IT-4 and IT-6. MSG-37 through MSG-75 (potions/scrolls/daemon expiry) by IT-5. MSG-76 through MSG-88 (traps/search) by IT-6. MSG-89 through MSG-100 (sticks) by IT-5. MSG-101 through MSG-184 (inventory/equipment/misc) by IT-6. MSG-185 through MSG-195 (wizard) by IT-9. MSG-196 (browser startup) by IT-7.

3. **Scenarios collectively cover every AC group**: Build (IT-1), Deliverable (IT-1, IT-7), RNG Fidelity (IT-2), Dungeon Gen (IT-3), Monster Fidelity (IT-4), Combat Fidelity (IT-4), Item Fidelity (IT-5), Daemon/Fuse (IT-3), Hunger (IT-6), Level Progression (IT-3), Commands (IT-6), Display (IT-7), Save/Load (IT-8), Wizard Mode (IT-9), Deterministic Replay (IT-2, IT-3, IT-4, IT-6).
