oh-my-codex v0.16.4

0.16.4 is a post-0.16.3 reliability release for approved execution handoffs, context-pack metadata, Codex hook feature-flag migration, setup/notify ownership, HUD/runtime state-root visibility, Ralph completion audit evidence, and Ultragoal completion proof requirements.

Highlights

• Approved execution handoffs are more durable — Ralph, Team, and planning now preserve approved context references, ready context-pack role refs, private context-pack entry metadata, canonical approved PRD aliases, multiline launch hints, visible hint lineage, and approved handoffs during Team scale-up.
• Codex hook setup stays compatible across CLI releases — setup probes supported Codex feature flags, writes [features].hooks = true when available, retains the legacy codex_hooks fallback for older CLIs, dedupes stale hook aliases, keeps hooks active after clear resets, and detects stale PostCompact wiring.
• Runtime ownership and visibility are safer — OMX notify dispatch avoids recursive wrapper chains, setup mode switches avoid duplicate hook state, plugin-mode skill discovery and plugin MCP cleanup are hardened, boxed Team state-root precedence is corrected, and HUD visualization stays rooted in runtime authority.
• Completion gates are harder to overclaim — Ralph completion requires audit evidence, and Ultragoal final completion requires cleanup/review proof before accepting done state.

Validation

• Local release-review gates: npm run build, npm run lint, npm run check:no-unused, node --test dist/cli/__tests__/version-sync-contract.test.js, release-focused targeted Node suites, cargo test, npm pack --dry-run, and git diff --check.
• Release body generation is a pending pre-tag gate tracked in docs/qa/release-readiness-0.16.4.md; run generate-release-body.js against the local annotated v0.16.4 tag before pushing the tag.
• GitHub CI and publication evidence are tracked in docs/qa/release-readiness-0.16.4.md; pending gates must be filled after CI, tag workflow, GitHub release, and npm verification complete.
