 - Sprint 13 "Sound" briefings — 9 tickets across server, client, audio, visual teams; full audio architecture + gauntlet expansion + monologue display spec
 
 ### Fixed
+- Entity renderer field name bug — `id` vs `entity_id` (#345)
+- Dialogue max-width pixel value — 640px per D-076 (#447)
 - Routine tests missing ActiveSim — 3 of 5 tests passed trivially without the required tier marker
 - `_observer_pos` misleading unused prefix renamed to `observer_pos` (used for sound event filtering)
 - Stale protocol version doc comment "Current: 9" corrected to 10
 - FactionOnly non-numeric `faction_id` attribute now logs a tracing::warn instead of silently denying
+- SOUND_EVENT_ASSETS walk-speed key mismatch — `sfx_footstep_metal` corrected to `sfx_footstep_metal_walk`
 
 ### Changed
 - Removed orphaned `SimulationTier`/`LastInteraction`/`ScopeTag`/`ScopeKind` types from tier.rs (unused outside own tests)
 - Sound pipeline documented as intentionally empty in v0.1 (no producers yet, full pipeline wired)
 - Observer test setup now inserts SoundEventQueue resource for integration coverage
 - Added FactionOnly positive test case and Medium-range occlusion TODO
+- Sound indicator colors sourced from Constants instead of duplicated hex literals
+- play_loop() null guard on stream.duplicate()
+- Camera zoom fallback uses Constants.CAMERA_DEFAULT_ZOOM
