+Official store ID 67, ZIP SHA-256 `91c388d3c1b52079314045b79671ad55c767510658b6193f6936ed6cad383b94`; the exact `main.py` SHA-256 is `2303ec70c262f1cbfe1c8c138770c6e7c3496827e748e679c94ca43ff9f28725`. The BSD-licensed archive requests `_root`, hard-codes Steam Deck `BAT1`, raises on empty history, and drops the final sample in per-app grouping. The backend records local battery readings in plugin runtime SQLite; it does not need privileged writes for the verified path.
+
+The digest-scoped managed install removes `_root`, discovers a readable supply whose `type` is `Battery` (preferring `BAT1` on Deck), fixes empty and single-sample history, retains pending samples while the panel is open, and flushes them on unload. The original ZIP and license remain pinned in the test fixture. Changed archive bytes still fail the root gate; other root plugins remain blocked.
+
+Under a unique owner token on `/tmp/frame-test.lock`, a **read-only** real Frame probe found SteamVR activity `3` (standby), proximity raw `2.25`, and one Battery-type supply named `max1720x_bat_7-36`. It exposed readable `capacity` (89%), `status` (Charging), `voltage_now`, and `current_now`; `power_now` was absent. The owned lock was released. No wake, input, normal service, power setting, or plugin install was touched.
+
+In network/device-isolated, unprivileged **actual Decky 3.3.0 amd64**, the exact adapted archive was discovered. A private Frame-shaped supply fixture produced history and per-app power through public legacy RPC. The complete native regression runner, including existing negative controls, passed. Local managed install/remove tests and the exact-source/manifest guard passed. CI's native ARM64 and fake Frame e2e jobs remain required before merge.
+
+This supports **partial** compatibility. The official frontend initialized in the earlier opaque Chromium audit with backend calls denied; it has not been tested with these live samples. Actual managed recording on Frame ARM64, long-term history, foreground-app attribution, panel controls, and worn VR remain unverified. Existing copies need update or reinstall.

 After the VR job released the shared lock, this audit acquired it and used a private temporary Decky 3.3.0 ARM64 user service. Read-only ProtonDB `get_setting` and Steam Status `get_settings` calls succeeded through the live Steam CEF websocket. The service and private base were removed and the lock released; normal managed services stayed inactive, battery was 100 → 99, and no power setting was changed. [Redacted results](evidence/framey-official-backend-2026-10-25.json) record exactly what ran. A [2026-10-26 follow-up](evidence/framey-events-backend-2026-10-26.json) verified default Notebook drawing/save/reopen across a real backend restart and Simple Timer start/cancel, countdown/completion events, a visible toast and persisted recents/subtle mode. Only private test settings were written. That initial pass left Simple Timer partial because its own expired-timer startup raises a missing `timer_task` error; sound/suspend are unsupported. A [local audio follow-up](evidence/framey-audio-backends-2026-10-26.md) exercised Volume Mixer, Volume Boost and Mixer through real Decky 3.3.0 amd64 backends on private silent virtual audio targets. Sliders, numeric volume entry, independent server readbacks and Mixer filter persistence across a runtime restart passed. An [ARM64 audio follow-up](evidence/framey-audio-arm64-2026-10-26.md) verified the unmodified official backends in actual Decky 3.3.0 on the Frame user audio session. Volume Mixer and Mixer now qualify as works for per-app volume: Chromium controls changed only a named silent stream, with independent Pulse readbacks. That run left Volume Boost partial because sink writes were denied. A [Volume Boost follow-up](evidence/framey-volume-boost-arm64-2026-10-26.md) now verifies linked/separate channel controls, re-link and reopen through the actual ARM64 backend. Independent Pulse reads confirmed 125%/150% gain writes while the default sink stayed muted; exact original volume/mute was restored. Volume Boost qualifies as works for sink controls. Audible output, Bluetooth playback and worn VR remain unverified. A [running-context follow-up](evidence/framey-running-context-2026-10-26.md) supplies detached running-app/main-app reads and relays actual Steam lifetime callbacks while a panel is open. Real Frame checks verified an empty list, registration/cleanup and the exact Discord Status ARM64 backend reporting no IPC connection. Nonempty games and transitions were synthetic fixtures; real game events, Discord activity and worn VR remain unverified. Discord Status moves to partial; no new works claim is made. A [library context follow-up](evidence/framey-library-context-2026-10-26.md) read 1,106 app overviews, 895 game IDs and the current public Steam ID from real Frame CEF under the shared lock. Local Chromium replayed this detached snapshot to render Deck Settings game selection, Steamback's empty save panel and PlayTime statistics/settings. Steamback and PlayTime used actual Decky 3.3.0 amd64 backends in an isolated container; their ARM64 backends and automatic game hooks remain unverified. Shotty's frontend now starts, but its published backend fails on missing `click`; it stays broken. A [chunked frontend follow-up](evidence/framey-deck-shelves-browser-2026-10-26.md) loaded Deck Shelves 2.0.0 through a managed JavaScript module route and rendered its settings in an opaque local Chromium panel. Its backend was denied; Steam Home shelves and worn VR remain unverified. A [local module lookup follow-up](evidence/framey-module-lookup-2026-10-26.md) supplies a finite registry of Framey-local controls and CSS. TabMaster QAM/docs now render; Steam library-tab editing remains unavailable. That pass exposed Junk-Store executable-script extraction failures; the follow-up below repairs them. SteamGridDB still requires Steam context-menu internals and DeckSP still fails its published MobX fallback. That pass tested TabMaster/Junk-Store in actual isolated amd64 Decky, without ARM64 or worn-VR coverage. A [script entrypoint follow-up](evidence/framey-script-entrypoints-2026-10-26.md) grants owner execute to shebang scripts and ZIP-declared executables without copying archive privilege/write bits. Junk-Store now passes static menu/backend calls in actual Decky 3.3.0 ARM64 and local Chromium Games/Epic navigation, back and reopen. It moves to partial: About still crashes on missing installed-app metadata, Legendary is absent, and login/game operations remain unverified. Existing installations require update/reinstall to repair permissions. A [read-only installed-metadata follow-up](evidence/framey-installed-context-2026-10-26.md) now repairs the About crash. The library snapshot copies only Steam-supplied installed booleans into detached metadata, preserving unknown values as undefined. Junk-Store About/Dependencies, Back and reopen render in local Chromium with actual Frame library data and the official ARM64 backend. It remains partial: dependency/login/game operations, RSSLine truncated
