Add compact readiness, capability, and live-validation reports

[remybanks77]

Status

Draft/parking branch only. Do not review or merge this PR as-is.

This was stacked on #313, but #313 was closed unmerged on 2026-05-27 with maintainer guidance to split the work into smaller focused PRs. This branch is now retained as an integration/evidence branch for local validation and as source material for the split PRs.

Summary

The branch contains the compact release/readiness, capability-gap, and redacted live-validation reporting work that was originally stacked on #313:

• 7f38e98 Add compact release readiness doctor
• 01ab174 Add Linux capability gap doctor
• 6f882ee Add redacted live validation matrix
• f116044 Add redacted live validation collector
• 015af40 Add redacted live service lifecycle probe
• 210d02b Add redacted parity evidence bundle
• b347eee Cover thread goal lifecycle parity
• 8ad1688 Merge remote-tracking branch 'origin/main' into codex/release-readiness-doctor

Highlights:

• Adds codex-desktop-doctor --readiness and codex-desktop-doctor --capability-gaps without claiming official Linux support or exact macOS parity.
• Adds redacted desktop/keyring, service lifecycle, and browser evidence collectors plus make parity-live-matrix, make parity-services-live, and make parity-evidence.
• Adds isolated thread/read plus thread/goal/set, thread/goal/get, and thread/goal/clear parity coverage against a temporary home/config/repo and non-user thread, without printing thread ids, goal text, or thread content.
• Restacks the branch on current origin/main, preserving upstream Nix pin rollout safeguards and the current remote-control visibility-gate fix while keeping the Node 24 GitHub action pins.

Validation

Local on 8ad1688:

• .github/workflows/*.yml parsed with PyYAML.

• node --test linux-features/remote-mobile-control/test.js -> 55 pass / 0 fail.
• git diff --cached --check && git diff --check
• node scripts/app-server-schema-guard.js --json -> pass.
• node scripts/desktop-parity-smoke.js --json --skip-cdp -> 34 pass / 1 CDP skip / 0 fail.
• node scripts/parity-evidence-bundle.js --json -> pass.
• bash tests/scripts_smoke.sh -> all script smoke tests passed.

Split Path

Maintainer-requested split order from #313:

1. Managed Node runtime real-JS probe.
2. Update-builder/schema/patch validation changes.
3. Flatpak Chrome extension integration.
4. Installed codex-desktop-doctor.
5. Optional codex-desktop.service user service.
6. Parity smoke/schema tooling and docs.
7. Secret Service support for remote-mobile-control keys.

Notes

This remains an unofficial Linux build/readiness/capability report. It does not claim official OpenAI Linux Desktop support or exact macOS parity.
