 ## Unreleased
 
+- Fix smoke cleanup skipping orphan metadata and Steam shortcuts after a test
+  title directory was already removed. Sweep and verify all six exact reserved
+  smoke IDs; preserve similarly named titles. Make `scripts/frame-smoke.sh`
+  work with POSIX sh and Python 3 without zsh, including from another working
+  directory. Local regressions cover both fixes; no new headset run.
+
+- Skip backup saves and settings reached through a symbolic link anywhere below
+  the home folder, and recheck paths before packing each file. Local synthetic
+  tests cover redirected Proton prefixes and links changed after discovery;
+  concurrent filesystem changes can still race the checks.
+  [Backup layout and limits](docs/backup-and-recovery.md).
+
+- Import a base APK with supported native-library or asset splits from a local
+  Android backup or XAPK/APKS/APKM bundle. Check package and version before
+  install; refuse resource, code and feature splits and device-variant sets.
+  This route has local fixture coverage, not a real split-game headset test.
+
 - Save Steam screenshots under a separate folder for each headset, Steam
   account and game. Equal screenshot filenames no longer overwrite one another;
   existing files in the old flat folder are left in place.
   [Copying guide](docs/recording.md).
 
+- Keep Steam clip exports separate for each headset, Steam account and nested
+  recording session. Manual export and automatic copying use the same folders;
+  existing flat exports stay untouched and do not mark unrelated clips saved.
+  [Recording guide](docs/recording.md#steam-clips).

   Highlight exact PnP instances and known state changes after a dropout;
   incomplete inventories stay unknown. A Forget button clears the comparison.

+
+On a real Frame with Frame OS 0.5.6 build `20261022.6153909`, SteamVR 2.18.2
+reported `activity_level` 3 (standby). The battery was 99% before and after.
+The test downloaded the official store's current archives, checked each SHA-256
+against store metadata, and inspected their manifests and binaries. For seven
+non-root candidates, the removable user-service loader started each plugin in
+turn. It stopped between plugins. Logs showed `Loaded <name>` for all seven.
+The service and test folders were removed after the run; the owned shared lock
+was released. **A load message is not proof that a plugin's page, settings, or
+action works in VR.** No plugin was tried by a wearer.
+
+| Official store plugin (tested version) | Result | Evidence and limit |
+| --- | --- | --- |
+| ProtonDB Badges 1.3.4 | Partial | ARM64 backend loaded. Earlier 1.1.0 also registered in the shared Gamepad UI; badges in the VR shell were not seen. |
+| CSS Loader 2.1.3 | Partial | Backend loaded; one `SyntaxWarning`. Theme controls and CSS application in VR were not checked. |
+| SteamGridDB 1.8.1 | Partial | Backend loaded. Artwork selection and its UI were not checked. |

+| Decky Recorder | Not in current official store | No matching plugin appeared in the official store list on this date; no archive was installed. Frame Control's own headset panel has a separate recorder. |
+
+The table reflects the tested versions only. Other releases can change their
+files or behavior. The official store's digest checks the archive in transit;
+it does not certify plugin code. Plugins run with the headset user's access.
+For a new plugin, follow the [Frame plugin and extension guide](frame-plugin-author.md).
+
+The new store transaction was also exercised on the same real Frame:
+**managed loader install → ProtonDB Badges 1.3.4 store install → status →
+store update → store remove → managed loader remove**. Status reported the
+managed store ID and version while the plugin was installed. The service
+remained active after each store change. The battery was 99% before and after.
+The test removed its plugin folder, loader, and owned lock. This validates the
+store file and service path over SSH, not a visible VR plugin page.
+
+Frame Control's desktop app and opt-in headset panel now show official store
+entries. Install, update, and remove need an explicit confirmation. They only
+change Frame Control owned plugin folders under
+`~/.local/share/frame-control/decky/plugins`. The installer checks the store
+hash and archive paths, blocks root plugins and non-ARM64 binaries, and rolls
+back an update if the service restart fails. The current VR shell does not
+provide Decky's Steam Deck Quick Access Menu. Frame Control's headset panel
+shows installed plugins and store actions. Its separate Framey iframe now hosts
+compatible API v2 plugin pages, settings, local routes, and panel toasts.
+Steam route patches and system notifications remain unavailable. The panel
+still needs a worn-headset visual and controller check. See the

+# Auto-sync retry and headset-selection reliability
+
+Date: 25 October 2026. Base: `d79efb4`, Frame Control v0.4.30.
+Issue: [#214](https://github.com/saphid/frame-control/issues/214).
+Environment: Linux x86_64, Python 3.12.3, Node 24.15.0.
+
+## Reproduced problems
+
+The existing 19 auto-sync tests passed on the base revision. Added regressions
+failed before the implementation: an exhausted clip lost its error, explicit
+retry did not recover failed screenshots or clips, and switches around listing
+or copying continued the old pass. The original callback interface also had no
+way to carry the tick's captured device into the server list reservation.
+
+The final fake-source tests exercise these boundaries:
+
+- Fail screenshots or clips three times, keep checking without further copy
+  attempts, and retain the source error plus an explicit retry instruction.
+- Recover the source and use either Resume or Copy everything now without
+  restarting. Successful copies stay deduplicated; Resume retains the ledger
+  even after a local file is deleted. Copy everything now retains its documented
+  ability to restore deleted files and include older media.
+- Reset an exhausted budget while the source still fails: another three
+  attempts are allowed, rather than unlimited background attempts.
+- Save an exhausted item by hand and clear its stale failure on the next list.
+- Switch after tick captures A, during a list, after screenshot bookkeeping,
+  between media kinds, before a transfer, or before transfer bookkeeping.
+  Interrupted passes do not mark the other headset's IDs or continue copying.
+- Switch to B exactly at callback entry through the production `_sync_list`
+  adapter. `working(A)` refuses before calling the source list, leaving both
+  ledgers and copy callbacks untouched. The same production reservation blocks
+  a device switch during a list and rejects stale screenshot/clip transfers.
+- Execute the production Settings renderer in Node: Resume is available for
+  copy errors and disk-full pauses, and hidden for a healthy state.
+
+## Implementation boundary
+
+Each list callback now receives the captured device, like the copy callbacks.
+The existing server `working(meant)` mechanism checks that intended headset
+under `_work_lock` while reserving work; `devices_post` uses the same lock to
+refuse switches during that work. The worker also checks for interruption
+around lists and transfers. No new device lock or clip destination logic is
+introduced. The server diff is confined to `_sync_list`.
+
+The failed-attempt and error maps are in-memory and reset on explicit retry or
+restart. The successful-copy ledger and settings persistence retain their
+existing format. Disk-full pauses, offline backoff, clip settling and the
+three-attempt limit remain covered by the original tests.
+
+## Checks
+
+- `python3 -m unittest discover -s tests -p test_autosync.py -v`: 33 passed.
+- `python3 -m unittest discover -s tests -p test_shot_copy.py -v`: 2 passed.
+- `python3 -m unittest discover -s tests -p test_clips.py -v`: 34 passed,

+- `python3 -m py_compile ui/frame_autosync.py ui/server.py tests/test_autosync.py`
+  and `git diff --check`: passed.
+
+- `python3 -m unittest discover -s tests -v`: 1,525 tests run in 184.876
+  seconds, passed with 16 skips. Ran with sandbox escalation for loopback
+  sockets; test isolation still used throwaway app/SSH data and mocked headset
+  transport. Final output:
+
+  ```text
+  Ran 1525 tests in 184.876s
+  OK (skipped=16)
+  ```
+
+## Limits and handoff
+
+All new regressions use fake sources and mocked transport; they do not prove
+real-headset transfer or UI rendering. No headset was accessed: its shared test
+lock was held by another task. The Docker fake-Frame end-to-end suite and
+Windows/macOS runs were not performed locally. The coordinator owns review and
+merge; this task does not release, change PR #113, or publish announcements.

+with the Framey React/DFL shim. The [browser screenshot](framey-browser-2026-10-25.png)

+# OBS end-to-end validation — 25 October 2026
+
+**Passthrough: yes.** Real room pixels behind SteamVR panels appeared in the
+live `/dev/video99` mirror, the saved OBS recording, and a decoded frame at
+four seconds in a production MP4. The Frame was safely woken with
+`vrcmd --handlewakeup`; no camera, power or compositor settings were changed.
+This establishes the checked SteamVR mirror, not every game/mode or Steam's
+own clips. Treat recordings as potentially showing the room.
+
+## Environment and provenance
+
+- Host: lxso2, Linux x86_64. Real OBS 30.0.2 in disposable Ubuntu 24.04/Xvfb,
+  using software llvmpipe rendering and the Media Source `ffmpeg_source`.
+- Frame: SteamOS 0.5.6, build `20261022.6153909`, SteamVR 2.18.2, reachable
+  with the existing `ssh frame` connection. Hardware use was serialized with
+  coordinator mppkd9qczt through `/tmp/frame-test.lock` and a unique owner.
+- Released v0.4.30 AppImage SHA-256:
+  `b1335bb06130f2cce64a0dd40a8cb60a52c68effc258dc4bc35f8c40c822d5bb`.
+  The long recording started through this app's actual Electron IPC, Python
+  helper and SSH stream. Robustness checks then used that released runtime
+  with the final changed resources and repacked `app.asar`; this was not a
+  newly built AppImage. No OBS plugin or host FFmpeg is required by the app.
+- Windows release ZIP SHA-256:
+  `a393cc1653f14f162b4a3e56803f7fe9bea7b04904d18577b0b2d7d7c2d95b03`.
+  Checked against release SHA256SUMS; bundled Python 3.12.14.
+
+Machine-readable measurements and the manual stimulus/analysis programs are
+in [obs-validation-2026-10-25/](obs-validation-2026-10-25/).
+Room images and videos remain private under `/tmp/obs-aacapv3evh` on lxso2;
+only their hashes are committed in `private-artifacts.json`.
+
+## Recording, sound, sync and latency
+
+| Check | Measured result | What it establishes |
+| --- | --- | --- |
+| Real OBS recording | 187.367 s; 15,784,412 bytes; H.264 1280×720 at 30 fps; 5,621 decoded video frames; AAC 48 kHz stereo | More than three minutes through the packaged Linux path |
+| OBS dropped frames | 0 encoder skips; 90 render lag/stall frames, approximately 1.6% of recording frames | The software-rendered host was not lossless; this is not a hardware-rendered performance benchmark |
+| Audio | 1 kHz stimulus; FFT peak 996.094 Hz at 11.719 Hz bin resolution; peak −13.207 dBFS; 0 clipped samples; measured harmonic energy −81.32 dB relative to fundamental | Non-silent, no numerical clipping or large harmonic distortion in the checked tone; no listening or real-game quality verdict |
+| Baseline A/V | Audio leads video by median 426.67 ms; range 360–426.67 ms across 36 pulses | Default OBS setup needs sync checking; not suitable for a claim of automatic accurate sync |
+| Live image latency | 1,431.4 ms, n=1; clock exchange RTT 3.409 ms; screenshot polling about 20–35 ms | Overlay submission to OBS source screenshot, not physical headset motion-to-photon latency |
+| Production MP4 | 5.121 s; 1920×1080, 30 fps, 153 video frames; AAC stereo; request to saved result 7.435 s | A separate production recorder saved room passthrough pixels too |
+
+The manual stimulus places an owned black/white OpenVR marker over the mirror
+and plays a 200 ms, 1 kHz tone every five seconds through the Frame's default
+output. `pa_simple_get_latency` estimates when the submitted samples play;
+marker submission is aligned to that estimate. This measures software output,
+not an externally measured loudspeaker/physical-display event. Most submission
+jitter was below 0.2 ms; compositor timing and the 30 fps/10 ms analysis grids
+still limit precision. FFmpeg decodes both tracks; the analysis detects marker
+edges and groups AAC pre-echo onsets within 100 ms.
+
+A separate initial +400 ms OBS Sync Offset trial left 83.33 ms of audio lead.
+Changing the offset during an already active source from 0 to +367 ms did not
+improve that run (366.67 ms before, 370 ms after). Do not assume a universal
+offset or that a live setting change has taken effect: reopen the source and
+verify another recording. Three subsequent fresh-source trials, setting the offset **before activating**
+the Media Source, measured 480 ms audio lead at 0 ms, 70 ms lead at +400 ms,
+and **0 ms at +480 ms** across three pulses (30 fps video and 10 ms audio
+analysis resolution). This proves a setup-specific workaround, not a universal
+default. See `calibration-initial.json`. Full trial measurements are retained. Zero OBS
+buffering caused missing/distorted sound and was rejected. Zero mux delay
+and alternate timestamp experiments did not improve latency and were not
+merged. The default capture/encoding settings remain unchanged.
+
+## Robustness and fixes
+
+| Failure or scenario | Fix / result | Proof |
+| --- | --- | --- |
+| Stop during asynchronous Python discovery could still launch later | Cancel the pending generation; expose Stop while starting | Controller regression test |
+| Late stderr containing an earlier ready message changed stopping back to running | Only accept ready while starting; ignore stale child events | Original released block reproduced in `race-before.json`; controller regression |
+| A non-responsive SSH process defeated timeout termination | Bounded terminate/wait then kill; SSH connection/keepalive bounds | Real SSH child deliberately stopped with SIGSTOP; clear UI failure in 15.009 s including 5 s forced cleanup; both processes gone |
+| Timeout with the app's stdin still open aborted Python at shutdown | Read the control descriptor directly, avoiding a blocked buffered-stdin daemon lock | Previously reproduced fatal shutdown; final real stall shows `The Frame OBS video stopped for 10 seconds`; subprocess regression holds stdin open |
+| Three Start/Stop cycles | First packets 0.890 / 0.701 / 0.709 s; Stop to idle 61.7 / 52.7 / 53.0 ms | Final patched packaged runtime, ports 15101–15103, `robustness.json` |
+| Restart after stall | First packet 0.691 s | Same runtime and real Frame |
+| Quit while streaming | No surviving helper at 2.021 s | Same runtime; final audit found no test FFmpeg/stimulus process |
+| Port 15099 occupied | App now offers a validated alternate port and matching copyable URL | OBS occupied 15099 while real packets arrived on alternate ports; UDP cannot identify or guarantee the receiver |
+| OBS before/after Start; receiver restarts | Live decoding verified, including recreated sources while relay stays active; an already-open stalled receiver may need hide/show or properties OK | Documented recovery, not automatic OBS control |
+| Standby/wake | Safe wake changed a blank mirror to visible room/panels | Private mirror and saved recordings |
+
+A forced SSH stall tests the transport failure and error/cleanup behavior.
+It does **not** prove real Wi-Fi loss or full headset suspend/resume. No physical
+network interface was disabled and no headset reset was performed. There is
+no automatic reconnect: restore connectivity and press Start. Valid blank
+standby frames do not trigger a packet timeout.
+
+## Windows and macOS
+
+**Windows controls remain hidden.** A disposable Windows 11 VM ran the final
+helper using the released app's bundled Python and a native executable SSH
+fixture. It stayed alive for three seconds without a UDP receiver, then sent
+1,316-byte packets when a receiver opened. Closing its control pipe returned
+exit 0 with no surviving SSH child (`windows-pipe.json`; stop measured below
+the VM timer's resolution in the final run). The helper hides the SSH console
+and tolerates Winsock's delayed UDP receiver-unreachable error.
+
+The real-headset Windows attempt delivered zero packets through a temporary
+host SSH bridge. Native Windows OBS, direct Windows-to-Frame SSH, firewall
+behavior and packaged app Start/Stop have therefore not passed end to end.
+No local FFmpeg was installed; encoding belongs on the Frame. No firewall
+exception, headset authorized key, or Windows scheduled task was installed.
+
+**macOS:** no physical Mac or macOS VM was available. Python tests and the
+five controller lifecycle tests run in the macOS CI matrix; these cannot
+establish capture performance, audio quality, packaged launch or OBS behavior
+on a physical Mac.
+
+## Validation and remaining limits
+
+Local suite: **1,514 Python tests passed, 16 skipped**, 46 app tests and 18
+site tests passed. The latest helper additionally passed all 11 focused OBS
+tests; the controller passed all five focused lifecycle tests. Cross-platform
+CI results belong to the linked PR, not these host measurements.
+
+Still unverified: perceptual listening, real-game audio routing, accurate
+default A/V sync, broad latency/performance across hosts, hours-long sessions,
+physical Wi-Fi drop/full suspend recovery, physical macOS and native Windows
+OBS. The app/docs now explain copyable URL/format, receiver recovery, port
+selection, passthrough privacy and OBS Virtual Camera's video-only limit.
+The Discord guide provides the corresponding audio-sharing choices.
+
+Cleanup completed: Steam and vrcompositor remained running, battery 98%,
+no test FFmpeg/stimulus process remained, UDP ports 15099/15101/15102/15103/15105
+were bindable, task guest SSH config and the temporary bridge were removed,
+and the owned headset lock was released. The disposable Windows VM was
+stopped with its disk retained. See `cleanup.json`.

+# Round 2 retry, 25 October 2026
+
+The provider retry completed four further fixes, each in an isolated child
+worktree with its own issue, branch, PR, tests, docs and Announcement draft.
+The coordinator reviewed each patch, independently ran focused tests, verified
+its exact head and complete CI, merged it, then read back GitHub's merged state.
+PR #113 was untouched. No social announcements were posted.
+
+## Merged fixes
+
+| Change | PR | Merge commit | Coordinator focused tests | Final CI |
+| --- | --- | --- | --- | --- |
+| Skip linked backup ancestors and recheck before packing | [#215](https://github.com/saphid/frame-control/pull/215) | `da34d94` | 34 passed | 11 checks passed at `8cc03c8` |
+| Clean orphan smoke metadata/shortcuts; POSIX runner without zsh | [#216](https://github.com/saphid/frame-control/pull/216) | `d5fa8fe` | 17 passed | 10 checks passed at `a5daa4a` |
+| Separate Steam clips by headset/account/full session ID | [#217](https://github.com/saphid/frame-control/pull/217) | `1255ef2` | 62 passed | 10 checks passed at `7dfe777` |
+| Retry failed automatic copies and bind listings to the captured headset | [#218](https://github.com/saphid/frame-control/pull/218) | `fdd60d3` | 33 passed | 10 checks passed at `af2bb17` |
+
+Two initial CI fixture failures were fixed before merging: macOS temporary-path
+aliases needed a resolved working directory in the wrapper test; Windows
+needed explicit UTF-8 when reading the Settings test's HTML fixture.
+Concurrent main changes #208/#209/#210 were preserved. Changelog conflicts
+retained both entries. No history was rewritten.
+
+## Integrated validation
+
+At main `1255ef2`, after all four merges:
+
+- `python3 -m unittest discover -s tests`: 1,559 tests, 16 skipped, passed in
+  157.335 seconds. Loopback networking was enabled for local HTTP fixtures.
+- `node --test app/test/*.test.js site/test/*.test.mjs`: 59 tests passed.
+- Worker backup validation also passed both Docker recovery-kit E2E tests in
+  an isolated Compose project, then removed its containers, volumes and network.
+- Local proof logs: `/tmp/frame-round2-integrated-tests.log` and
+  `/tmp/frame-round2-integrated-node.log`. Individual focused logs use
+  `/tmp/frame-round2-{backup,smoke,clips,autosync}-review.log`.
+
+## Real Frame smoke
+
+The current host is lxso2; its existing direct `ssh frame` alias works.
+Another OBS task initially held `/tmp/frame-test.lock`, so only read-only
+checks were done until it released the lock. This coordinator then acquired it
+atomically and labeled it `frame-round2-vdw4yh1xv8-20261025`.
+
+The merged `scripts/frame-smoke.sh` ran directly without zsh at 06:38:37 UTC.
+All 13 steps passed on SteamOS 0.5.6, BUILD_ID `20261022.6153909`. The ARM64
+and Proton titles ran. The x86-64 Linux title reported its runtime missing,
+an explicitly accepted smoke outcome rather than a successful execution.
+Installs/removals succeeded; the Windows title's remove
+step stopped five test-owned PIDs. Both final process sweeps were empty.
+Independent readback found no reserved title folders or metadata, SteamVR's
+PID was unchanged, and the three observed gamescope focus properties matched
+before/after. Battery went from 99% Charging to 100% Full. Only this task's
+lock was removed, and its absence was verified.
+
+[Sanitized structured proof](round2-smoke-2026-10-25.json). Raw local results:
+`/tmp/frame-round2-smoke-results/2026-10-25T063837Z-20261022.6153909.json`;
+console log `/tmp/frame-round2-headset-smoke.log`; state readbacks
+`/tmp/frame-round2-smoke-before.txt` and `/tmp/frame-round2-smoke-after.txt`.
+
+The headset was unworn. Visible rendering/controller input was not verified.
+No pairing, password/security change, reboot or factory reset was performed.
+The new backup/clip/auto-sync paths have local fixtures and cross-platform CI;
+this smoke does not establish a new real-data backup/clip/UI test. Synthetic
+orphan metadata was not seeded on the real device. Backup path checks retain
+a documented race with concurrent filesystem changes.
+
+## Prior round-two work reconciled
+
+The failed coordinator checkout was still at v0.4.7. It was first updated to
+main `d79efb4`, already v0.4.30. Earlier PRs had completed clipboard testing
+(#124), original smoke process cleanup (#126), Windows VM capture (#129),
+battery health (#125), setup doctor (#127), and read-only storage (#128).
+Later evidence already covered real clip export (#147/#149/#154/#156) and
+Return to Game Mode (#143/#157). These remain earlier evidence, not tests
+performed by this retry. Physical Windows GPU/input and current physical
+macOS checks remain incomplete; see the current support matrix.
+
+Decision: fix reproduced data/cleanup/retry defects rather than automate game
+moves without a verified transaction API or promise unverified phone-background
+sync. Prepare v0.4.31; publication still requires its Linux AppImage install test.
+
+## Delegation provenance
+
+All implementations completed. Task IDs use prefix
+`node:delegated-task:command%3Amcp%3Ad9bc35d8-0e9c-42c2-b798-25bd8af94d81%3Adelegate-task%3A`

+[#212](https://github.com/saphid/frame-control/issues/212).
+Host: Linux 6.8.0-139-generic, Python 3.12.3, ffmpeg 6.1.1.
+
+## Baseline reproduction
+
+Loaded the unmodified `ui/frame_clips.py` from `d79efb4` into a temporary
+Python module and exported three fake sources into a temporary directory:
+
+```
+1/clips/clip_620/video/bg
+2/clips/clip_620/video/bg
+1/clips/clip_620/video/other
+```
+
+Each source's payload was its own ID. All three exports returned the same
+destination, `clip_620.mp4`; listing marked all three saved. The final file
+contained only the last source ID. No SSH or headset was used.
+
+## Regression coverage
+
+`tests/test_clips.py` exports five IDs on each of two fake headsets, including
+equal clip names across accounts, nested sessions with equal leaf names,
+different leaf names under one clip and the background/clip distinction.
+All ten payloads survive at distinct destinations. Listing marks only the
+identities already exported. A pre-existing flat MP4 retains its original
+bytes and does not mark any identity saved. Normal export still returns
+`message` and `file`, removes its remote temporary export and clears local
+staging; a failed re-export preserves the completed file.
+
+`tests/test_clip_copy.py` exercises the server's list and manual export
+functions and its actual auto-sync callbacks with fake transport. A manual
+copy is recognised by auto-sync, all other account/session identities copy,
+and switching to a second headset copies its own sources without overwriting
+the first. A delayed manual job refuses a changed headset with status 409.
+Both local phone mode and local headset runtime reject Steam clip list,
+export and auto-sync requests with status 400. The separate `Recorder` path
+is unchanged.
+
+## Validation
+

+  — 66 tests passed in 17.288 seconds, no skips. Includes real ffmpeg/ffprobe
+  export of a generated 65-second DASH fixture and recording stop/cleanup.

+- `python3 -m py_compile ui/frame_clips.py ui/server.py tests/test_clips.py tests/test_clip_copy.py`
+  and `git diff --check` — passed.
+
+The server and full Python suites require localhost sockets and were run
+outside the network sandbox. Tests import `tests/sandbox.py` to isolate app
+data, SSH settings, home directories and service URLs.
+
+## Limits and upgrade behaviour
+
+No real headset was accessed: the shared device lock is held by other work.
+This is Linux fixture and server coverage, not a fresh packaged-app or
+Windows/macOS verification. Existing real-headset export evidence in the
+recording guide predates this destination change.
+
+Old flat exports cannot prove headset/account/session identity and are left
+untouched. Previously remembered auto-sync IDs retain their existing
+watermark/history behaviour; **Copy everything now** or manual **Export**
+creates an identified copy. No release, version bump, merge or social post
+is included. PR #113 is outside this task.

+
+There are two paths. Choose the one that matches your feature.
+
+## Frame Control extension
+
+Use a Frame Control extension for a panel, status view, or guide that does not
+need to change the headset. Put `extension.json` and `index.html` in one folder
+under `~/.local/share/frame-control/extensions`. The opt-in headset panel lists
+the folder and opens it in a sandboxed iframe. The version 1 bridge has only
+`capabilities` and read-only `status`. It cannot call Steam, change settings,
+or run privileged code. See [the extension API](extensions.md) and its example.
+
+## Decky plugin
+
+Use a Decky plugin only if you need Decky's backend or Gamepad UI integration.
+Build an official-format ZIP with one top-level folder, `plugin.json`, and a
+frontend bundle in `dist/index.js`. A Python `main.py` backend is optional.
+Test on ARM64. If you ship an ELF helper, build it for AArch64 (ELF machine
+183). Avoid root, `sudo`, Steam Deck TDP controls, fixed x86 binaries, and
+paths under `/etc`. Frame Control's managed loader is a normal user service;
+it blocks root plugins and x86 archives. Keep data under your plugin folder or
+the user's home directory, and provide a removal path.
+
+The current Frame SteamVR shell does not expose Decky's Steam Deck Quick Access
+Menu. A backend `Loaded` log only proves backend startup. Test any frontend
+page, setting, notification, route, and controller input while wearing a Frame
+before describing it as working in VR. Until a QAM bridge is verified, a Frame
+Control extension is the simplest route for a self-contained read-only VR panel.
+
+Frame Control now has an experimental [Framey panel host](framey-loader.md)
+for API v2 Decky frontend bundles. It renders common settings controls in the
+separate SteamVR dashboard panel, but Steam library and store page patches
+remain unavailable. Wearer-visible use is not yet verified.
+The [settings sample](../examples/framey-settings/README.md) shows an official
+Decky JSX build, backend persistence, a toggle and a local toast. Framey offers
+only official-store-owned plugins in its VR panel.
+
+To test safely, use a separate Frame Control managed Decky install, verify the
+ZIP digest from the official store, install one plugin at a time, and inspect
+`journalctl --user -u frame-control-decky.service`. Remove only your own
+plugin folder when you finish. See the current [compatibility table](decky-frame.md).
+
+## Framey API v2 compatibility
+
+Framey hosts a plugin's frontend in an isolated iframe in the Frame Control
+SteamVR panel. The table describes the current implementation and its tests;
+none of these frontend controls has passed a worn-headset check yet.

+| `PanelSection`, rows, buttons, toggles, dropdowns | Local touch-sized controls | Local browser and host unit test |
+| Optional `settings`, `frameyQuickActions` | Separate settings tab; up to eight actions with result text | Host unit test; these fields are Framey additions |
+| `serverAPI.call` / `callable` | Calls only that plugin's Decky Python backend via the headset service | Fake Frame e2e for setting read/write across CEF calls, update, and reinstall; host unit test. Real Decky persistence remains unverified. |
+| `toaster.toast` | Visible toast inside the plugin panel; `dismiss` and optional `onClick` | Host unit test; no Steam system notification |
+| `routerHook.addRoute` / `removeRoute`, `Navigation.Navigate` / `NavigateBack` | Local routes inside this plugin panel only | Host unit test |
+| `routerHook.addPatch`, global components | No-op; cannot patch Steam routes | Not applicable |
+| Steam library/store patches, CEF tab injection | Unavailable; no matching target in the isolated panel | Frame CEF inspection |
+| `fetchNoCors`, Decky event listeners, file picker, root calls | Unavailable | Not supported by Framey |
+
+Keep routes local to the panel and give every operation a visible result. A
+plugin that calls `Navigation.Navigate('/decky/store')` will not open the
+Frame Control store; only paths registered by that same plugin can navigate.

+# Framey loader on Steam Frame
+
+Framey is an experimental bridge for Decky store plugins inside Frame Control's
+SteamVR dashboard panel. It is opt in. The panel and Decky backend are ordinary
+user services under `~/.local/share/frame-control`; neither needs root or a
+read-write SteamOS root filesystem. Decky's standard Quick Access menu still
+does not appear in the separate SteamVR CEF target.
+
+## Use in the headset
+
+Install **Frame Control in VR** and **Decky Loader on Frame** from Frame Control
+on your computer. Open the Frame Control tab in SteamVR, then choose **Decky
+plugins → Open official store**. Search the catalogue, confirm an install, and
+choose **Open panel** from the installed plugin list. The panel contains the
+plugin's own controls and settings. Update and Remove affect only plugin
+folders that Frame Control's store manager installed.
+Removing a plugin keeps its Decky settings. Removing the Frame Control headset
+panel or Decky backend keeps plugin folders until each is removed separately.
+
+Frame Control's existing official-store manager downloads a published ZIP from
+Decky's content-addressed CDN, verifies its store SHA-256 hash and manifest,
+rejects unsafe ZIP members and root plugins, and swaps one managed plugin
+folder with rollback on failure. It rejects non-ARM64 ELF and Windows binaries.
+The Decky user service restarts after a file change. Framey's panel host accepts
+only API v2 bundles with `dist/index.js`; other installed plugins remain
+manageable but have no Framey panel. The store manager does not currently
+screen a plugin's runtime network downloads.
+
+## What the compatibility host supplies
+
+The plugin bundle runs in an opaque-origin iframe in the Frame Control SteamVR
+panel. It receives React 18.3.1, a small `DFL` panel-control shim, and the
+Decky API v2 `call`/`callable` interface. Backend methods are sent by the
+authenticated parent to Steam's existing `SharedJSContext` CDP client, then
+through Decky's *existing* websocket connection. Framey never opens a second
+Decky websocket, because Decky allows only one frontend connection. The iframe
+does not receive Frame Control's UI key. React and ReactDOM are bundled for
+offline use under their MIT licenses in `ui/vendor`.
+
+The host currently supplies sections, rows, buttons, toggles, dropdowns,
+scroll containers, a modal, locale information, local panel routes and toasts,
+and backend calls for the plugin that owns the panel. Steam library/store page
+patches, global Steam UI components, file pickers, and privileged root methods
+have no VR target. A plugin that depends on them can render only part of its UI
+or show an incompatibility message. A Decky plugin's Python backend still runs as
+the headset user when Decky loads it, so review third-party code before opting
+in. The panel iframe can make HTTPS requests subject to ordinary browser CORS.
+
+ProtonDB Badges' current API v2 bundle rendered its settings in a local Chromium
+browser with a stubbed backend reply on 25 October 2026. Its controls accepted
+pointer input. This does **not** verify SteamVR visibility, controller input,
+live Decky settings persistence, or badges on Steam game pages. The last item
+has no supported injection target in the Frame Control panel.
+The [browser and fake Frame evidence](evidence/framey-browser-2026-10-25.md)
+records exactly what was exercised.
+
+The fake Frame integration test now writes a Decky setting through Framey's
+scoped backend endpoint, reads it in a new CEF request, updates the plugin,
+then checks it again. It also confirms removal blocks method calls and a
+reinstall can read the retained setting. This tests the bridge and fixture;
+real Decky settings persistence on a worn Frame is still unverified.
+
+The in-headset **Open official store** view loads the full official catalogue.
+Search matches names, authors, and descriptions. Filters show non-root plugins
+or installed plugins, and Previous/Next buttons browse 20 results per page.
+The root label is a compatibility warning; other APIs are checked only when a
+plugin is opened. The store still needs the managed Decky user service running
+before its Install or Update buttons are enabled. If a plugin prevents Decky
+from starting, Remove remains available for Frame Control-owned plugins while
+the managed service is stopped; it does not restart the service.
+
+Install, Update, and Remove show the current job stage in the headset panel.
+The store verifies each downloaded archive and the headset applies it with a
+rollback if Decky cannot start. The panel remembers the current job ID for this
+browser session, so **Check result** can resume polling after a navigation or
+temporary connection error. Refresh the installed list before starting another
+operation after an error. If Frame Control restarts, it cannot recover the old
+job result. The panel clears that job ID and asks you to refresh the installed
+list before making another change.
+
+## For plugin authors
+
+Start with the [Framey settings sample](../examples/framey-settings/README.md)
+for a buildable Decky API v2 panel and Python settings backend.
+
+Publish a normal [Decky store](https://plugins.deckbrew.xyz/) API v2 release
+with `plugin.json`, a single `dist/index.js` ESM frontend entry point, and a
+Python backend if needed. Give the frontend a `content` React element returned
+by `definePlugin`, and build settings as panel controls from `@decky/ui`.
+Backend calls through `@decky/api` reach only that plugin's own backend.
+For best VR compatibility, keep the panel self-contained and use `PanelSection`,
+`PanelSectionRow`, `ButtonItem`, `ToggleField`, and `DropdownItem`. Handle a
+missing Steam UI route, store overlay, or `SteamClient` object gracefully.
+Avoid root, remote binary downloads, Steam library patches, and assumptions
+about Steam Deck hardware. Declare settings defaults so a fresh user service
+can render without pre-existing files. Test your ZIP with the store validator
+and the fake Frame flow before asking users to install it.
+
+An API v2 plugin's normal `content` is its default VR panel. Framey also shows
+an optional `settings` React element under a **Settings** tab and an optional
+`titleView` above it. For one-tap headset controls, return
+`frameyQuickActions: [{label: 'Refresh data', onClick: refreshData}]` from the
+plugin initializer. Framey displays up to eight actions and reports a pending,
+success, or failure state. These descriptor fields are Framey additions; Decky
+ignores them. Use a plugin backend method through `@decky/api` for work needing
+persistent state, and keep a quick action safe to repeat.
+See the [API v2 compatibility table](frame-plugin-author.md#framey-api-v2-compatibility)
+for tested behavior and remaining limits.
+
+The [Frame Control extension API](extensions.md) is an alternative for a
+Frame-specific panel. It needs only a local manifest, HTML, and the read-only
+`status` bridge; it does not need Decky.
+
+## Removal
+
+Use **Remove** on each installed Framey plugin, then **Remove managed Decky**
+and **Remove** under Frame Control in VR. These operations remove only
+Frame Control-owned folders and services. Settings, the Chromium profile, and
+other users' plugins are preserved. To remove one managed plugin manually,
+first inspect its `.frame-control-store.json` receipt in
+`~/.local/share/frame-control/decky/plugins/<folder>`, then delete only that
+folder and run `systemctl --user try-restart frame-control-decky.service`.
+The Decky and headset service manual removal commands are in
+[Decky on Frame](decky-frame.md#opt-in-and-remove) and
+[Frame Control in the headset](headset-app.md#remove).
+
+## Fast worn-headset check
+
+With an already installed Framey plugin and someone wearing the headset, run
+`python3 scripts/framey-worn-check.py` from a paired computer. The script
+atomically acquires `/tmp/frame-test.lock` before reading battery or SteamVR
+activity. If another job owns the lock, it makes no sensor reads. It releases
+its own lock without starting the interaction when the headset is in standby.
+Within 35 seconds, use a controller
+to open a managed plugin panel and touch one setting. The script records a
+fresh trusted pointer event, the panel-ready event, SteamVR overlay visibility,
+and a stereo screenshot with varied pixels. It deletes its own short-lived
+challenge and releases only its own lock. It records the screenshot hash and
+color count, then removes the private temporary image from both devices.
+Pixel variety alone cannot prove the UI text was legible; a person must still
+confirm the view in the headset. The script does not install or remove a plugin,
+alter Steam settings, or wake the headset.

+# Plugin and modding research
+
+Checked **2026-10-25**. Decision: keep the experimental, reversible Decky manager
+and ship Frame Control's own sandboxed panel API as the supported way to add
+local features. Both implementations already landed in the replacement job
+while the original job was unavailable. This report consolidates their evidence
+and the original research questions; it does not claim another loader was built.
+
+## Can Decky run on Frame?
+
+**Its ARM64 backend and Steam shared-context injection work on the tested build.
+A usable Decky menu inside VR remains unverified.** Do not equate an active
+service or a JavaScript plugin registration with a working headset interface.
+
+| Requirement | Evidence | Consequence |
+| --- | --- | --- |
+| ARM64 Linux binary | Upstream [3.3.0](https://github.com/SteamDeckHomebrew/decky-loader/releases/tag/v3.3.0) has `PluginLoader-arm64`; Frame reports `aarch64` | ARM is not itself a blocker. Individual plugins may still ship x86 binaries or assume Deck hardware. |
+| Steam Gamepad UI and CEF | Loopback `127.0.0.1:8080/json/list` exposes `SharedJSContext` plus distinct SteamVR pages | The shared context exists; the VR shell is a separate integration target. |
+| CEF enable marker | `~/.steam/steam/.cef-enable-remote-debugging` is absent, but CEF already answers | No marker or Steam launch flag change is needed on this build. |
+| User service manager | `systemctl --user show-environment` succeeds | A per-user service works without installing an upstream root service. The manager is degraded by a stale failed Decky unit, although its unit file is gone. |
+| Filesystem | `/` currently mounts `rw` on Btrfs, `/home` mounts `rw` | This is an observation of this device, not a stock-image guarantee. Do not disable SteamOS read-only protection or install packages in `/usr`. |
+| Homebrew folder | `~/homebrew` is absent | It is an installer convention, not a preinstalled SteamOS plugin API. Frame Control uses a separate managed directory. |
+| Visible menu | Earlier tests registered Decky's tab only in shared JavaScript; SteamVR had no Decky overlay; headset was in standby | QAM visibility, controller input and a real plugin's visible result remain unverified. |
+
+The fresh [read-only probe](evidence/plugins-2026-10-25.json) records SteamOS
+`0.5.6`, `VARIANT_ID=vr`, build `20261022.6153909`. It confirms CEF, architecture,
+mounts, user-service availability, and absence of a running managed or upstream
+Decky installation. This retry did not install anything or restart Steam.
+
+The replacement job's initial [test record](decky-frame.md) reports:
+
+- Decky 3.3.0 started as the normal `steamos` user and injected into
+  `SharedJSContext`.
+- Install → status → update → status → remove → status succeeded on the Frame.
+  Removal left the unit, binary and port 1337 absent, while preserving user data.
+- ProtonDB Badges 1.1.0 loaded as a passive plugin and appeared in Decky's
+  shared-context registry. Its badge or menu was not seen inside VR.
+- Injected frontend code can outlive backend removal until Steam's web helper
+  restarts. An earlier helper-restart test cleared the globals; this retry did
+  not repeat it.
+
+These are prior documented results, separate from the fresh read-only probe.
+The coordinator then ran a separate, locked
+[official-store compatibility audit](decky-frame.md#official-store-plugin-audit-2026-10-25)
+on the same Frame OS build. Seven plugins logged backend loads. A managed
+ProtonDB Badges 1.3.4 store install, update and remove also succeeded. The
+headset stayed unworn, so these results still do not establish VR UI use.
+
+## Installer and update choice
+
+The upstream [installer at e42a3c8](https://github.com/SteamDeckHomebrew/decky-installer/blob/e42a3c828de90673959b4de26cf5c5d2c7830554/cli/install_release.sh)
+escalates through sudo, creates `~/homebrew/plugins` and `services`, writes the
+CEF marker and a system unit under `/etc/systemd/system`, and starts Decky as
+root. Its architecture switch supports `aarch64|arm64`. Running this installer
+is unnecessary for a compatibility check and grants more access than a panel
+extension needs.
+
+Frame Control's [manager](../ui/frame_decky.py) instead downloads the official
+ARM64 asset, checks GitHub's published SHA-256 and the ELF machine, and writes
+only under `~/.local/share/frame-control/decky` and `~/.config/systemd/user`.
+It refuses an upstream system-service installation, requires active CEF before
+install/update, and restores the previous binary, receipt and unit if applying
+an update fails. Existing tests exercise that rollback with a failed service
+start. These checks do not prove every possible OS or Steam update is safe.
+
+The binary is downloaded on demand, not bundled. Plugin discovery lists the
+managed directory and upstream `~/homebrew/plugins`. The later
+[store manager](../ui/frame_decky_store.py) exposes official entries in the PC
+app and opt-in headset panel. It verifies archive digests, blocks root and
+non-ARM64 binaries, and changes only its own plugin folders. That is file and
+backend support, not a working VR plugin page. Decky plugins can execute
+backend code and are not isolated by Frame Control's HTML extension sandbox.
+
+Home-directory state is expected to survive SteamOS image updates, based on
+SteamOS's layout; **an actual OS update and reboot persistence test has not been
+performed**. Steam frontend changes, CEF availability, libc requirements and
+plugin hardware assumptions can still break Decky. On failure, remove the user
+service using [the documented removal command](decky-frame.md#opt-in-and-remove);
+its removal path does not require a working CEF target. Test the sequence again
+on each supported OS build before expanding support claims.
+
+## Other paths
+
+| Path | What it enables | Current limits and choice |
+| --- | --- | --- |
+| Decky plugins | Steam frontend hooks, optional Python backends | Seven official-store plugins logged backend loads on ARM64. Store install/update/remove worked for ProtonDB Badges. VR pages and controller input remain unverified. Keep experimental. |
+| [CSS Loader](https://github.com/suchmememanyskill/SDH-CssLoader) / [DeckThemes](https://docs.deckthemes.com/) | Stylesheets applied to Steam UI | CSS Loader 2.1.3 backend loaded on Frame. No theme was applied or visually tested. Deck themes do not establish compatibility with Frame's separate VR shell. |
+| User home / SteamOS homebrew | User services, user Flatpaks, files and helpers | Use owned folders and explicit uninstall. A folder named `homebrew` supplies no discovery or security boundary by itself. No rootfs changes needed for the chosen path. |
+| Android / Lepton | Sideloaded apps, game-specific content and per-app settings | Frame Control already manages APKs and ADB. Lepton runs Android containers, not Steam's CEF UI; an Android mod does not add a Steam dashboard tab. No new Android mod was tested here. See [APKs](apks.md), [VR APKs](vr-apks.md), and [game mods](mods.md). |
+| Frame Control extensions | Third-party HTML/CSS/JS panels with a small read-only bridge | Shipped in [#194](https://github.com/saphid/frame-control/pull/194), with a manifest, local folder, sandbox, example and [author guide](extensions.md). No Python imports, arbitrary SSH commands or write actions are exposed. |
+| Frame Control's headset panel | Runs the local tools and extensions as a SteamVR panel | Shipped in [#198](https://github.com/saphid/frame-control/pull/198), expanded in [#201](https://github.com/saphid/frame-control/pull/201). Page/API execution and uninstall were tested; wearer-visible pixels and controller interaction remain unverified. See [test record](headset-app.md). |
+
+The extension iframe has `sandbox="allow-scripts"`, an opaque origin, restrictive
+CSP and a `postMessage` bridge accepting only `capabilities` and a reduced
+`status` snapshot from the active frame. It is useful for local dashboards and
+small tools today. It cannot replace the full Decky API. Third-party code still
+needs review: an iframe may navigate itself externally, and local installation
+does not establish publisher trust.
+
+Extensions are loaded only when opened and are removed by closing their panel
+and deleting their own directory. They modify no SteamOS files. The
+[compatibility follow-up](https://github.com/saphid/frame-control/pull/209) adds
+manifest `apiVersion` validation during discovery and asset serving, with
+existing manifests defaulting to version 1. It rejects incompatible panels
+even when requested through a direct asset URL.
+
+## Licences: separate download versus bundling
+
+Decky's [licence](https://github.com/SteamDeckHomebrew/decky-loader/blob/00cd202872b85868071b041c8f1b34e734147195/LICENSE)
+is GPL version 2. Frame Control is MIT-licensed. The integration contains its
+own service-management code and downloads the upstream executable as a separate
+program. It does not incorporate Decky source or ship its binary in Frame
+Control installers. Keep the upstream licence/source links visible to users
+who opt in; installing a separate GPL program does not by itself relicense
+Frame Control's independent code.
+
+If a future release bundles or mirrors Decky binaries, the distributor must
+preserve copyright/licence notices and satisfy GPLv2's corresponding-source
+requirements for the exact binary, including modifications and build scripts
+as applicable. A link to an evolving default branch is not a substitute for
+meeting those distribution obligations. Mere aggregation and deriving or
+linking a combined work are different questions; reassess the boundary if
+Decky code is incorporated. Each plugin, theme and bundled dependency has its
+own licence and assets to check independently. The existing
+[third-party notices](../THIRD_PARTY_NOTICES.md) describe software already
+distributed with Frame Control.
+
+## Next checks
+
+1. On a worn Frame, establish an accessible Decky menu or implement an adapter
+   for the VR shell. Verify a plugin's visible result and controller navigation
+   before describing store-installed plugins as usable inside VR.
+2. Verify the Frame Control panel and example extension visually, including
+   opening, refreshing and closing with the controllers.
+3. Test a normal Steam restart, reboot and SteamOS update with a disposable
+   managed install; confirm removal still works with CEF unavailable. Retain
+   the experimental label until those checks pass.
+
+The release coordinator owns those ongoing headset-integration checks. This
+retry leaves the headset untouched and hands over the research and compatibility
+follow-up instead of running concurrent loader experiments.

+```sh
+pnpm install --frozen-lockfile
+pnpm build
+pnpm exec tsc --noEmit
+```
+
+The committed `dist/index.js` is the built frontend. For a Decky release ZIP,
+put `plugin.json`, `main.py`, and `dist/index.js` inside one top-level plugin
+folder. Publish it through the official Decky store if you want Frame Control's
+managed installer to offer it. Framey deliberately opens only plugins that the
+official store installed and marked as owned; copying this example into the
+plugin directory does not enable its VR panel.
+
+## Test and adapt
+
+Run `python3 -m unittest discover -s tests -p test_framey_sample.py` from the
+repository root. It checks backend persistence and evaluates the built bundle
+against Framey's actual host script. The fake Frame store flow is exercised by
+the repository's e2e suite. No worn-headset visibility or controller-input test
+has passed for this sample yet.
+
+The plugin needs no root access or system changes. Its settings remain after
+the managed plugin folder is removed, following Decky's settings behavior.
+For a production plugin, add migration and recovery handling for damaged
+settings files, and test every UI path in a worn headset.
