oh-my-codex v0.12.1

Patch release for team/runtime hygiene, launch/cleanup follow-through, notify-fallback hardening, and release collateral alignment

0.12.1 follows 0.12.0 with the full v0.12.0..v0.12.1 patch train: clean machine-readable team status output, correct interactive worker PID metadata, launch-safe MCP cleanup, direct-leader launch follow-through, notify-fallback log hardening, tighter operator guidance, and synchronized 0.12.1 release collateral.

Highlights

• omx team status --json no longer risks stray mailbox-delivery stderr noise during stale leader-mail pruning.
• Interactive team workers now record the PID of their actual tmux pane, not a pane-index approximation.
• Orphaned OMX MCP cleanup now protects the live launcher tree, and notify-fallback once-mode logs no longer grow without bound.
• OMX now defaults to direct leader launch outside tmux unless detached tmux is explicitly requested.
• Release metadata and collateral are aligned to 0.12.1.

What’s Changed

Fixes

• avoid duplicate bridge MarkMailboxDelivered calls for already-delivered leader system mail
• persist interactive worker PID metadata from the resolved pane id
• preserve live launcher ancestry while reaping orphaned OMX MCP processes
• rotate notify-fallback once-mode logs under the configured size cap

Changed

• default leader launches to direct mode outside tmux unless --tmux explicitly requests detached startup
• tighten the information-architect prompt
• bump release metadata from 0.12.0 to 0.12.1 across Node/Cargo manifests, changelog, and release collateral

Verification

• npm run build
• npx biome lint src/cli/index.ts src/cli/cleanup.ts src/cli/__tests__/index.test.ts src/cli/__tests__/cleanup.test.ts src/scripts/notify-fallback-watcher.ts src/hooks/__tests__/notify-fallback-watcher.test.ts src/team/runtime.ts src/team/state/mailbox.ts src/team/__tests__/runtime.test.ts src/team/__tests__/state.test.ts package.json
• node --test dist/cli/__tests__/cleanup.test.js dist/cli/__tests__/index.test.js dist/cli/__tests__/version-sync-contract.test.js
• node --test dist/hooks/__tests__/notify-fallback-watcher.test.js
• node --test dist/team/__tests__/state.test.js dist/team/__tests__/runtime.test.js
• npm run smoke:packed-install

Remaining risk

• This verification is still local; it is not a full GitHub Actions matrix rerun.
• The release still touches live team/runtime and notification surfaces, so post-release monitoring should watch team status output, interactive worker lifecycle telemetry, and notify-fallback behavior.
