v4.12.0

Codex Has Teams Now

Codex can now work as a coordinated team, not just as one session plus isolated helpers. LazyCodex ships a Codex-only teammode skill that creates a named group of durable Codex threads under the current session as leader, records the team in .omo/teams, gives each member a concrete ownership area or perspective, and keeps shared artifacts on disk so the work can be inspected, resumed, archived, or deleted cleanly.

Team members are real Codex threads created through codex_app.create_thread, not ephemeral spawned agents. The bundled controller script owns team.json, guide.md, member bindings, status updates, artifacts, optional worktree paths, and cleanup. That makes team work useful for jobs where multiple perspectives need to coordinate with each other: code areas that overlap, release reviews, adversarial audits, broad investigations, and long-running parallel work where the leader still needs a durable control plane.

Safer LazyCodex Installs and Marketplace Payloads

LazyCodex installation is stricter about what it activates. Hook command targets are validated, Windows hook paths are covered, marketplace installs preserve their update and re-approval boundary, Bun global installs are detected more reliably, and Codex plugin hooks are now shipped as split per-hook manifests with display metadata that is easier to inspect.

Team Mode Guardrails

The team workflow now rejects weak or unsafe composition: single-member teams, duplicate member focus after trimming, spawn_agent substitutes, symlink writes into team guides, symlink-based delete escapes, and unresolved state paths. Members are also instructed to communicate frequently with small status updates, which makes the leader session much less blind during parallel work.

More Reliable OpenCode Runtime Wakes

OpenCode-side parent wake handling and delegate-task polling were hardened around stale sessions, live-route probes, placeholder sleep waits, terminal errors, background output polling, and plugin component reloads. The practical effect is fewer silent stalls when background work finishes or internal wakes race with session state.

Release Operations Now Fail Earlier

The publish workflow now gates npm publication on the release source-state PR landing first. If protected-branch checks or branch rules block that PR, publishing stops before packages are pushed to npm, preventing a repeat of the half-published v4.12.0 failure mode.
