Resident roles: charters installed as standing goals make unassigned threads self-run turns (codex >=0.146); please make goal installation opt-in + add thread/goal/clear

[bretttully-vh]

Summary

scripts/lib/resident-ensure.mjs unconditionally installs each resident role charter as a standing thread goal (thread/goal/set) in both startRoleThread and resumeRoleThread. Under codex CLI >= 0.146 (where the app-server auto-starts goal turns from standing objectives), this causes resident role threads to run turns nobody assigned:

• A role charter is a non-terminating objective — it can never be satisfied — so the runtime re-arms a new goal turn within milliseconds of each completion (we observed 2–9 ms).
• Unassigned resident threads (e.g. a reviewer/researcher role that has received no work) self-run autonomous turns indefinitely. In our deployment, idle role threads self-ran for ~2.5 weeks; rollout files grew to ~1.4 MB per thread with zero assignments.
• Worse, a goal turn can start concurrently with an actual assigned task turn on the implementer thread, producing a two-writer hazard inside a single working directory (we observed duplicated edits from overlapping turns in one repo checkout).
• Broker/thread status reports idle / activeTurnId: null while these goal turns are executing, so the behavior is invisible to normal supervision.

Note the goal-set signature predates 0.146 in our logs — 0.146's auto-start changed the severity, not the mechanism.

Asks

1. Make standing-goal installation opt-in (config/env flag), or stop installing role charters as goals entirely — a charter is descriptive context, not a completable objective. We have locally gated both thread/goal/set calls behind an env flag (default off) as a containment patch.
2. Expose a thread/goal/clear API. Today there appears to be no way to remove a standing goal from a thread; that blocks the cleaner end-state of setting a per-task terminal goal at dispatch time and clearing it on completion.

Environment

• codex-cli 0.146.0 (model gpt-5.6-sol), plugin codex@openai-codex v1.0.6, resident triad via the broker daemon
• macOS (Darwin 25.5), Claude Code 2.1.220 host

Repro sketch

1. Bootstrap the resident triad (three role threads) with the stock resident-ensure.mjs.
2. Assign no work to reviewer/researcher threads.
3. Observe rollouts: goal turns start unprompted and re-arm continuously; thread status remains idle throughout.
