+# Framey detached Steam library context — 2026-10-26
+
+Framey now reads a bounded library snapshot before importing official frontends
+that reference `appStore`, `collectionStore` or `m_CurrentUser`. It supplies app
+IDs/names/types/game IDs, sorting/playtime scalars, the actual all-games
+collection and the current public Steam ID. It does not copy credentials,
+balances, account names, filesystem paths or executable Steam objects.
+
+The projection is a fixed, parameterless `GetLibrarySnapshot` read through the
+existing installed-store-plugin boundary. The parent checks the iframe source,
+session, method and empty argument list. The host validates rows before exposing
+detached Maps and lookup methods. Plugin patches remain local to that iframe.
+Missing or invalid data leaves the globals unavailable and logs a clear warning;
+there is no invented account or empty-library fallback. Reopening the panel
+refreshes the snapshot. Live MobX observations, account-switch notifications and
+running-game events are outside this change.
+
+Library-sized backend arguments now have a 256 KiB UTF-8 JSON budget. The old
+8 KiB ceiling rejected normal app-name maps. Payloads travel as quoted literals
+on SSH stdin, avoiding operating-system limits on a single command argument.
+Store receipt ownership, method validation and legacy keyword envelopes still
+apply. The library read has a separate 2 MiB / 10,000-app limit; other Steam
+reads retain their 256 KiB response limit.
+
+## Observations
+
+| Plugin | Verified behavior | Remaining limit |
+| --- | --- | --- |
+| Steamback 1.0.0-1 | Panel opens; account setup and empty save-list reads succeed through actual Decky 3.3.0 amd64 | Private container had no Steam saves. ARM64 backend, backup/restore and automatic hooks unverified. Partial. |
+| PlayTime 3.2.5 | Actual backend selects the user, returns empty statistics; statistics panel and routed settings/tabs render | No sessions were created. ARM64 backend, existing databases, live observations and automatic recording unverified. Partial. |
+| Deck Settings 1.2.6 | Installed game picker renders the real Frame folder/name snapshot; search modal opens | Remote reports/proxy fetch, settings changes and ARM64 backend unverified. Partial. |
+| Shotty 0.1.0 | Library-based initializer now completes | Exact backend fails importing `click.get_app_dir`: `ModuleNotFoundError: No module named 'click'`. Archive does not bundle it. Broken. |
+| Discord Status 1.5.0 | Detached overview lookups available | Live running-app observations and artwork helpers remain absent; Discord activity unverified. Broken. |
+
+Exact plugin versions/digests, runtime digest, scoped calls and counts are in the
+[redacted observations](framey-library-context-2026-10-26.json). The canonical
+table/store labels use the same digest-scoped JSON. None of these plugins is
+promoted to **works** by this pass.
+
+## Verification boundaries
+
+- **Real Frame SSH:** atomic `/tmp/frame-test.lock` acquisition for every probe,
+  matching-owner release in `finally`. Frame OS 0.5.6 ARM64 Steam CEF returned
+  1,106 apps and 895 game IDs; no missing collection members or invalid rows.
+  The compact library-only response was 88,451 bytes. Current-user field shape
+  was separately inspected. Values remain private; only aggregate counts are
+  published. No wake, power/service changes or device artifacts were needed.
+- **Local Chromium:** production `headset.html`, current host, opaque iframe and
+  unmodified digest-checked official frontends. Library/user and install-folder
+  data were detached snapshots read from the Frame, replayed locally. This is
+  not a deployed headset HTTP or worn-VR test.
+- **Actual local backends:** published Decky 3.3.0 amd64 executable, private
+  unprivileged container, network disabled, capabilities dropped, no devices,
+  host home, saves or Steam files mounted. Only account setup within private
+  plugin data and read methods were allowed. Backup, restore, aggregation,
+  screenshot rescue and game actions were denied. Shotty's import failure was
+  observed from the runtime log before invoking screenshot methods.
+- **Catalog regression:** 116 exact frontends attempted, 101 initializer-ready
+  and 15 failed, compared with 98 ready before this theme. Steamback, Shotty and
+  PlayTime gained initializer readiness; no previous ready state regressed.
+  Backend/network calls stayed denied in this sweep. Readiness alone does not
+  establish useful operation.
+- **Fake Frame:** 116 archive/transport cases; 60 install/remove cycles and 56
+  expected blockers. Official backend execution was stubbed. Its private
+  Compose containers, network and volumes were removed.
+
+The browser audit accepts `--library-snapshot /private/library.json` to reproduce
+the detached replay. This flag does not convert the audit into live Steam or
+backend evidence. Never commit personal library snapshots or account values.
+
+No worn-VR, physical controller, keyboard, automatic recording or backup claim
+is made. Further device backend checks still require the shared hardware lock.

+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.
