# Phase 06.3 Plan 10: D-40 Residual Tile Bounds Summary

**RoomRenderer now filters `layout.tiles` to declared room bounds before creating Phaser tile sprites.**

## Accomplishments

- Added a `validTiles` guard using `width_tiles * tile_w` and `height_tiles * tile_h`.
- Kept raw `tilesOOB` telemetry intact so staging can still report malformed payloads.
- Did not change server payload shape or bump `PROTOCOL_VERSION`.

## Task Commits

1. **Task 1/2: RoomRenderer bounds guard** - `05db3c8` (`fix(06.3-10)`)

## Verification

- `pnpm --filter @rebno/client test --run` - PASS, 26 test files passed, 190 tests passed, 4 todo.
- `pnpm --filter @rebno/client typecheck` - PASS.
- Grep confirmed `PROTOCOL_VERSION` remains unchanged at 3.

## Next Phase Readiness

Ready for D-45 nameplate flicker/depth fixes and Wave-2 staging visual smoke.
