snapshot_history.py — async periodic capture per instance:
interval_sec / keep_last (FIFO eviction) / dir configurable
GET /snapshots/{instance}?limit=N → list metadata
GET /snapshots/{instance}/{filename} → image bytes
Persisted в /var/lib/cuda-grid/snapshots/{instance}/<ts>.png
layout_map / layout_filter_target в InstanceCfg — для будущей runtime switch
архитектуры (через streamselect либо filter rework — выбор за Phase 7).
Текущий _set_layout dispatches к layout_filter_target c index из map.
UI:
+ Layout buttons (quad/single/main_plus_preview placeholder)
+ Snapshot history grid с thumbnails (loaded /snapshots/{inst}?limit=24)
+ "Reload history" button

Static HTML/JS dashboard в cuda_grid_controller/static/index.html, mounted
на /ui и / FastAPI endpoints. Vanilla JS + HLS.js (CDN) для video player.
Controls:
Audio source — buttons из /audio/{instance} list, switch через POST
Intercom — Start (music↓) / End (restore)
Snapshot — opens PNG в new tab
Manual overlay — form для rect/text/dim/icon types
Chat — placeholder (info-toast про mosquitto_pub)
State — refresh каждые 2 sec, shows layout/overlays_count + raw list
Player consumes HLS на http://server:8888/live/index.m3u8 (mediamtx).
TV не нужен — браузер на любом устройстве в LAN.
