+# v0.4.50 candidate gate, 27 October 2026
+
+The version bump at `a160043` follows the merged Windows panel-response repair
+[#356](https://github.com/saphid/frame-control/pull/356) and the Framey changes
+[#353](https://github.com/saphid/frame-control/pull/353),
+[#354](https://github.com/saphid/frame-control/pull/354),
+[#355](https://github.com/saphid/frame-control/pull/355),
+[#357](https://github.com/saphid/frame-control/pull/357),
+[#358](https://github.com/saphid/frame-control/pull/358), and
+[#359](https://github.com/saphid/frame-control/pull/359).
+The exact DeckyFileServer catalog entry is **partial**; the shared Toggle fix
+does not promote any plugin status. Worn VR and physical controller behavior
+remain unverified.
+
+## Locked real Frame smoke
+
+Early `scripts/frame-smoke.sh` attempts exited before any headset read or test
+action because lxso2's Tailnet route was down and lxso1 lacked the authorized
+SSH key and pinned host record. No lock was taken by those attempts. The final
+run kept lxso2's existing private key and pinned Frame host key end to end,
+using lxso1 only as a TCP relay. A task-owned localhost tunnel reached the
+devkit endpoint after the runner acquired `/tmp/frame-test.lock`; no global
+SSH, network or security setting was changed.
+
+At **02:25:14 UTC**, `scripts/frame-smoke.sh` ran from candidate commit
+`fcae5d6` on Frame OS **0.5.6**, build `20261022.6153909`. Its locked
+read-only preflight found SteamVR activity **3 (standby)**, proximity raw
+**3.25** and battery **100%**. The result was **12 passed / one optional
+x86_64 launch skipped / zero failed**. ARM64 and Windows/Proton test titles
+installed, launched and were removed. The x86_64 title installed and was
+removed, but Steam Linux Runtime 4 was absent, so no x86_64 launch is claimed.
+Both the initial leftover sweep and final owned cleanup passed; the runner
+released only its lock. The private result is
+`/tmp/frame-control-v0450-smoke-results/2026-10-27T022514Z-20261022.6153909.json`
+(SHA-256 `7b8d88aafb4459bf882edeb10f65c021c5aa25ad9ed2755faf04e3b4a95c1632`).
+
+A separate read-only audit acquired a fresh unique lock after the smoke. It
+found activity **3**, proximity raw **3.25**, battery **100%**, no exact reserved
+`fc_smoke_*` or `fc-smoke-*` title directories or metadata, and no processes
+owned by those paths. That audit released its own lock. The local tunnel was
+stopped; the isolated lxso1 checkout and temporary SSH files were removed.
+There was no wearer confirmation, wake command or worn interaction test.
+
+## Remaining release gates
+
+The candidate needs green exact-head PR CI, e2e, native amd64/ARM64 Decky
+runtime checks and all four installer previews. After the candidate merges,
+its exact main commit needs green CI and e2e. The tagged release then needs
+every installer build, ten assets, matching checksums, release verification,
+independent package checks and publisher dry run. A failed, cancelled, skipped,
+pending or unverified release gate holds publication. The current published
+release remains v0.4.49.
