Release: promote measured ClosedRoom candidate

[daniele21]

Release intent

Promote the final integrated ClosedRoom candidate from dev to stable main under the repository RELEASE contract.

Candidate identity

• Candidate: dev@23dafebbc4f2c00a0b92496fe73085387ef6ee1f
• Candidate tree: 4fd02a28fa2b66716383546ae566b0c47d893fef
• Stable base: main@2e821c08fbba8b63fd866f155bb805096d36e029

Any subsequent dev movement invalidates candidate-bound evidence.

Automated release readiness

Current exact-candidate hosted evidence:

• Repository Health #370: PASS on 23dafebb…;
• RELEASE/FULL Remote preflight #378: PASS on 23dafebb….

Hosted CI establishes deterministic automated readiness only and never substitutes for target-Mac or Apple-authority release requirements.

REAL_ENVIRONMENT status

A fresh LOCAL REAL_ENVIRONMENT run has now been executed on current exact candidate 23dafebbc4f2c00a0b92496fe73085387ef6ee1f using exact artifact ClosedRoom-0.1.0-local-20260911T145416Z-cc6275-23dafebbc4f2.app.

The aggregate currently reports FAIL for both target_mac_recording_ui and seed_target_mac_recording_ui. This aggregate only exposes the wrapper checks, so the first nested UI checkpoint still needs to be read from ui-target-mac-report.json and contention-seed-ui-report.json before classifying the failure or changing code.

The immediately preceding representative-Mac run on 1db33c60… established PASS through packaged WKWebView accessibility, native capture + TCC, recording start/stop, persistence, both microphone + system-audio tracks, current post-stop Meeting workspace and Home search availability; both journeys then failed only at keyboard_cmd_k_search. PR #58 replaced global HID posting with PID-targeted key delivery and is included in current 23dafebb….

Because Apple Developer Program distribution authority is unavailable, LOCAL REAL_ENVIRONMENT can establish representative target-Mac behavior but cannot establish Developer ID signing, secure timestamp, app/DMG notarization and stapling, distribution Gatekeeper acceptance, or final release readiness.

Blocking release evidence

Do not merge this PR until all applicable release evidence matches the exact candidate:

• passing packaged WKWebView/accessibility/keyboard-focus journey, including Cmd-K search and Escape;
• TCC-backed native both capture with persisted non-empty microphone and system-audio tracks and clean lifecycle;
• real local MLX completion plus bounded CPU/RSS/scheduler/thermal observation;
• PRS-16 physical AI-busy contention proof with truthful Preparing recording, no premature capture and capture after the safe boundary;
• PRS-9 representative dual-track vs mixed-track benchmark;
• any materially required subjective VoiceOver/usability observation;
• Developer ID signing, timestamping, notarization/stapling and distribution Gatekeeper evidence if stable distribution is pursued.

A candidate/base move, material source edit, production artifact rebuild/signing mutation, or mismatched evidence invalidates affected release evidence.

Readiness classification

• Implementation complete: yes
• Integration complete on dev: yes
• Automated release readiness: PASS on exact candidate
• LOCAL REAL_ENVIRONMENT: current-candidate run executed; FAIL pending nested-check diagnosis
• Apple distribution authority: blocked / unavailable
• Release-ready: no
• Stable promotion to main: blocked

This PR remains an evidence-gathering boundary until target-Mac and distribution obligations are truthfully resolved.
