#115 Tiles 3 + 4: rewire scene_synthesis + audio cards#119
Merged
Conversation
Tile 3 of #115 — exposes the per-device scene_synthesis_cache (text narrative + ts_wall + face_id + state) over HTTP so the bridge dashboard's scene tile can read it instead of sharing an in-process dict that's no longer populated post-#36. Refs #115 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Tile 4 of #115 — exposes the per-device audio_cache (caption + timestamps + question + source) over HTTP so the bridge dashboard's audio tile can read it via the same cached/timeout/circuit-broken helper used for perception + vision rather than a shared in-process dict.

Tiles 3 + 4 of #115. Both caches are the same shape (per-device JSON metadata, no binary) so the rewire is a single bundled commit: - Add ``_dashboard_audio_cache_getter`` and ``_dashboard_scene_synthesis_cache_getter`` next to the existing ``_dashboard_vision_cache_getter``; both reuse ``_dotty_behaviour_get`` for the 2 s cache + 1.5 s timeout + circuit-breaker contract. - Drop the empty ``_audio_cache``/``_scene_synthesis_cache`` module dicts from bridge.py — nothing was writing them post-#36. - bridge/dashboard.py: rename the ``audio_cache``/``scene_synthesis_cache`` configure kwargs to ``*_getter``, add ``_audio_cache_snapshot()`` and ``_scene_synthesis_cache_snapshot()`` helpers mirroring ``_vision_cache_snapshot``, update the single read site in the perception card to call them. - Add bridge-side smoke tests for both getters (pass-through + degrade).

Summary
Bundled rewire of dashboard tiles 3 (scene synthesis) + 4 (audio) onto dotty-behaviour's HTTP surface — both caches share the same shape (per-device JSON metadata, no binary payload) so a single PR is the natural unit.
GET /api/scene-synthesis/recent— exposesPerceptionState.scene_synthesis_cache(text narrative + ts_wall + face_id + state). Lives in newroutes/scene_synthesis.py, wired intomain.pyalongside the other route includes.GET /api/audio/cache— exposesPerceptionState.audio_cache(caption + timestamps + question + source). Added to the existingroutes/audio.pynext to/api/audio/explain._dashboard_audio_cache_getter+_dashboard_scene_synthesis_cache_getterreuse_dotty_behaviour_get(2 s cache, 1.5 s timeout, circuit-broken).bridge/dashboard.py'saudio_cache/scene_synthesis_cachedirect-dict kwargs become*_gettercallables; added_audio_cache_snapshot()and_scene_synthesis_cache_snapshot()helpers mirroring_vision_cache_snapshot(Tile 2 model). Single read site in the perception card now calls them. The dead_audio_cacheand_scene_synthesis_cachemodule-level dicts on bridge.py (no writer post-Pi-runtime voice path v1 + full RPi decommission #36) are dropped.Test plan
