|
||
- `X17 (F15 × F17)`: `ViewportProfile` (`800x600` vs `1024x768`) + `AutomapView` (`overlay` vs `minimap_dock`) + `HudModel` panel layout.
|
||

|
||
- `S7`: End-to-end `.d2s` bot progression unlock + MCP character validation + D2GS cross-Act waypoint travel (Act 1 -> Act 5 Harrogath).
|
||

## 5. Escalations / Notes for Orchestrator
|
||
|
||
- **Zero Implementation Bugs in `src/**`**: All 20 features (`F1–F20`) implemented in `src/**` conform to their contracts in `PROJECT.md` and pass all 236 E2E tests.
|
||
- **Minor Pre-Existing Type Errors in Unit Tests Outside E2E Scope** (not modified due to strict file ownership):
|
||
1. `tests/client/client-world.test.ts:253`: `rawValue` property in `ItemStat` object literal (`ItemStat` uses `{ statId, param, value }`).
|
||
2. `tests/client/hud-session-play.test.ts:436`: mock `GameServerAdapter` literal specifies `close` instead of `disconnect`.
|
