+# Framey receipt guard, unworn Frame exercise (26 October 2026)
+
+The bounded `scripts/framey-vr-check.py --exercise` runner acquired `/tmp/frame-test.lock` with its own random owner before reading the real Frame. Its 05:26 UTC run used source commit `c2f94c242dac670e18259193311a7375f5a87942`. Preflight found SteamVR activity 3 (standby), proximity 6.25 and battery 99%. No wearer was confirmed.
+
+The temporary Frame Control dashboard overlay became visible to OpenVR. The stereo compositor image changed, and the `/dev/video99` mirror produced a frame. The sample settings panel displayed its stored off value, accepted a trusted synthetic OpenVR pointer event, saved on through the real Decky Python backend, read the setting from disk, and showed on after a fresh iframe reopen. The quick action read on. A native slider reached 50. Text entry used CDP after OpenVR focus. The runner exited 0 with `input.passed=true` and `compositorChanged=true`.
+
+The private capture files remain outside the repository at `/tmp/frame-pr301-unworn-vr-fixed/`. The before/after stereo SHA-256 values were `1683bf1dab70c1a0a1e8f313c8317dc04f992070b5b0de232de9008700130711` and `684a27eecf7bcbbc5308092ddbb1517c4596fb283e061e73dd6bb7f025954e8b`; the mirror frame SHA-256 was `5939149ea9c85fd2d86d3f8879c348f006c421a386bd66a93fe`. Room pixels are not committed.
+
+An earlier locked run at 05:24 UTC exposed a missing SHA-256 in the runner's temporary sample receipt: the new guard correctly asked to reopen the panel. Commit `c2f94c2` gives that sample a content digest; the second run passed. Both runs reported no cleanup errors, restored `power.pauseCompositorOnStandby=false` and `power.turnOffScreensTimeout=5`, removed their power recovery timers, and released only their own locks. Battery remained 99%.
+
+This is an **unworn sample-plugin result**. It does not prove wearer-visible pixels, physical controller input, native scrolling (the attempted scroll offset stayed 0), VR keyboard behavior, comfort, or any official Decky plugin's VR panel or backend. The hourly worn check remains enabled.

+# v0.4.42 candidate gate, 26 October 2026
+
+This branch bumps the app and lockfile to 0.4.42. It includes the [v0.4.41 release evidence](v0441-release-2026-10-26.md), the Framey panel lifecycle change in PR #299, the truthful optional-runtime smoke result in PR #300, the physical Intel Mac acceptance and host-test fixes in PR #303 (`fe1da43171883dc31161ff607c6b5a6ddf75f6ef`), and the receipt-bound API guard in PR #301 (`ad57662d40d3bbf6c850dd80ddc275280d389c86`). All 11 hosted checks passed on PR #301's exact head before its normal merge. The combined release candidate's own headset gates passed; exact-head CI and installer previews remain pending.
+
+The exact v0.4.42 candidate at `27af46dd20d7af30dde4c3f954d7b57b94843594` ran `scripts/frame-smoke.sh` under its unique shared lock at 05:40 UTC. Locked preflight found standby activity 3, proximity 6.25 and battery 99%. It recorded **12 passed / 1 skipped / 0 failed** on Frame OS 0.5.6 build `20261022.6153909`; ARM64 and Proton test executables launched. The x86_64 launch was skipped because Steam Linux Runtime 4 was not installed. Cleanup passed and the command exited 0. The private detailed result is `tests/smoke/results/2026-10-26T054014Z-20261022.6153909.json` in the candidate checkout. The prior PR #300 result is documented [separately](frame-smoke-runtime-skip-2026-10-26.md).
+
+The exact candidate then ran `scripts/framey-vr-check.py --exercise` under a fresh owned lock at 05:41 UTC. Preflight again found activity 3 and battery 99%. The real Decky sample setting saved `enabled=true` and survived a fresh iframe; the quick action read the same value. A trusted synthetic OpenVR pointer reached the panel; the sample slider reached 50 and CDP text entry after OpenVR focus reached `framey-ci`. Stereo compositor hashes changed from `38265343e13f5915869c9622ab1ceda7c31ab2e9b050f44564cfb9b6dc9f6e6d` to `64cc4c6f865bb8b2f756632c922d17dee12af40d480171586f2e9a51797b83e6`; the mirror capture hash was `165289dca9ad2bd895eb544f5be5d5fa2db7d2f635a927ac68a0c74267f69ee2`. The exercise exited 0 with `passed=true`, battery 99% afterward, original power values restored (`false` / `5.000000`), recovery timer removed, no cleanup errors and its own lock released. Its private full result is `/tmp/framey-v0442-exercise/result.json` on the test host. Synthetic scroll events left `scrollTop=0` and produced no wheel events. No person wore the Frame; physical controller interaction, official plugin VR panels, optical readability, VR keyboard and comfort remain unverified. The earlier [receipt-guard exercise](framey-receipt-live-2026-10-26.md) is separate evidence.
+
+The release tag and published installers do not exist at this candidate stage. Publication remains gated on this combined head's exact-head CI, then tagged installer checksums, package checks and public updater readback. The 116 exact-version Decky catalog remains **3 works / 48 partial / 54 broken / 11 N/A**; the two additional works claims are restricted to tested per-app silent-stream volume control. The official v0.4.39 Intel installer ran on a physical MacBook Air, but no tagged v0.4.42 Mac launch or real OBS audio/video check is claimed.
