# Goal Mode — Portable Fallback

This Skill generalizes the useful semantics of long-running Codex goal work without requiring Codex.

## Goal contract

Define:
- durable objective;
- hard constraints;
- acceptance evidence;
- authorized effects;
- stop conditions;
- current frontier.

## Runtime selection

If the active harness exposes a native durable-goal mode, use it.

Otherwise implement the same semantics through ANGENT Continuity:
- proactive frontier persistence;
- dependency-aware next action;
- periodic endpoint verification;
- no stop merely because a status report was produced.

## Stop

Stop only at verified goal completion, a true blocker, required user decision, authority boundary or exhausted explicit budget.

Never reinterpret “autonomous goal” as permission for unauthorized external effects.

## Stable 2.19.0 goal execution
Prefer actual Codex durable-goal support only when verified in the current runtime. In other harnesses, preserve the goal contract through Continuity without inventing a persistent background worker. Store objective, hard constraints, permitted effects, verifiable stop test, committed work, exact first unfinished step, active operations and dependency edges. On resume rebind the user-named workstream to live repository/provider state, rather than replaying a stale checkpoint.

Continue independent RUNNABLE units when one operation waits, and check only meaningful conditions. A progress response does not finish the goal; terminate only on verified endpoint, true blocker, explicit budget exhaustion or an authority/user decision boundary. No autonomous execution survives the host stopping unless a real scheduler exists.
