+# Framey session cache browser check, 25 October 2026
+
+Frame Control v0.4.34's opaque Framey iframe made the official Steam Status
+1.2.3 frontend log `SecurityError` for its `localStorage` cache. This follow-up
+used a per-panel memory substitute. It did **not** change the iframe's sandbox
+flags or give plugin code Frame Control's UI key.
+
+A local Chromium page loaded the unmodified official Steam Status 1.2.3 archive
+from `tests/fixtures/framey-official/123.zip` (SHA-256
+`9053308e04a74f44745b45b9f4f50af3673348d367e7b14bacc5677de707ac4e`).
+The page used `sandbox="allow-scripts allow-popups"` and returned `{}` for
+four `get_settings` calls. That reply was a stub, not the Decky backend.
+
+The iframe sent `framey:ready`. Its test script wrote and read a cache item.
+The parent could not read the iframe document (`contentDocument` was null).
+The plugin displayed Steam Status, Store, Community, WebAPI, Connection
+Managers and Players Online. Its public status request returned HTTP 200.
+No cache `SecurityError` appeared in the captured console, while the
+same archive had logged that error with the v0.4.34 host.
+
+Node host tests also checked item updates, removal, clear, key order, string
+conversion, quota rejection, and preservation of an existing item after a
+rejected write. The substitute keeps at most 256 items and 512 KiB of keys and
+values **in memory**. Closing or reloading the panel loses this cache. This
+check did not test offline behavior, persistent plugin settings, a live Decky
+backend, SteamVR visibility, controller input, or headset performance.

+# Steam Status in the local Framey browser, 25 October 2026
+
+This check used the unmodified official Steam Status 1.2.3 archive already
+pinned in `tests/fixtures/framey-official/123.zip`. Its SHA-256 is
+`9053308e04a74f44745b45b9f4f50af3673348d367e7b14bacc5677de707ac4e`.
+The archive declares Decky API v2. No headset was contacted for this check.
+
+On a Linux PC, we extracted the archive to a disposable plugin folder with a
+Frame Control store receipt. A local HTTP server served the page from
+`framey_panel.panel(123)`, Frame Control's React 18.3.1 runtime and its
+`framey-host.js`. A parent page put the panel in an iframe with
+`sandbox="allow-scripts"` and returned `{}` for the plugin's `get_settings`
+backend calls. This was a **stub**, not the Decky service.
+
+Chromium reported `framey:ready` and four `get_settings` calls. The page showed
+Steam Status, Store, Community, WebAPI, Connection Managers, Players Online,
+and other controls. Its own public `https://steamstatus.schelstraete.org/api/v1/status`
+request returned HTTP 200 and populated the status view. A click on **Refresh**
+sent Framey's trusted pointer event to the parent; this test did not prove a
+fresh status fetch or settings write. The [browser screenshot](framey-steam-status-browser-2026-10-25.png)
+contains only the local test page and public service data.
+
+The plugin logged `SecurityError` while reading and writing `localStorage` in
+the opaque-origin iframe. It caught the errors and rendered anyway. Its cache
+and offline behavior in Framey are **not verified**. The real Decky backend,
+live settings, SteamVR visibility, controller input and headset performance
+were not tested. This result supports only local frontend rendering for this
+exact archive and Frame Control v0.4.34 host code.

+# Pinned Decky store test archives
+
+These are unmodified ZIPs downloaded from the official Decky store CDN on
+2026-10-25. Each ZIP includes its upstream `LICENSE`. They are test data, not
+plugins shipped or installed by Frame Control. The fake Frame tests serve them
+from a local fixture so CI does not depend on the store being online.
+
+| File | Official plugin | Version | Store SHA-256 |
+| --- | --- | --- | --- |
+| `14.zip` | ProtonDB Badges | 1.3.4 | `90a3453ac02709cad64096e7539fd8141fa56f99ae3441fc24a4990dc9684358` |
+| `123.zip` | Steam Status | 1.2.3 | `9053308e04a74f44745b45b9f4f50af3673348d367e7b14bacc5677de707ac4e` |
+
+The matching source projects are
+[ProtonDB Badges](https://github.com/bschelst/protondb-decky) and
+[Steam Status](https://github.com/bschelst/steamstatus-decky).
+The test verifies the ZIP digest, archive policy, API v2 manifest, installed
+frontend bytes, managed store receipt, and removal. It does **not** run their
+Python backends or prove their JavaScript panels render in the VR shell.
