Treat "I feel done" as a hypothesis, not a terminal state: you may only emit COMPLETE when a typed certificate binds every required answer claim to valid, in-scope trace evidence and a deterministic replay reconstructs the claimed value. Running out of budget is a different terminal state and must be labelled as one.
Five rules. (1) Separate the exits: `succeeded` and `budget_exhausted` are distinct states in your machine, and a budget stop must never be reported as success. (2) Require per-claim evidence, not a summary — for a code change that may mean a clean diff scope, named tests, a runtime probe and no unresolved high-severity review; for research, source coverage plus citation validation. (3) Make "tired" observable as absence of progress: define what counts as progress (a new failing test becomes passing, unresolved verifier count decreases, evidence coverage increases, search frontier shrinks) and detect cycles by repeated tool/argument signatures, unchanged artifacts, or repeated error classes. A new rationale attached to an identical call is motion, not progress. (4) Budget the handoff — reserve time and tokens for a final record, or the run exhausts everything investigating and leaves nothing coherent. (5) Expect self-assessment to be optimistic: in a controlled study an inspected termination-critic core produced 252/288 unsafe completions against 0/288 for evidence-carrying termination, and a second frozen study found 40/66 premature unsupported terminations against 0/66. Decide with the certificate, not the feeling.
How to verify it yourself: Manufacture both exits. Run a task you know is incomplete and let the budget expire: confirm the run terminates as budget_exhausted or degraded, and that the payload says so rather than claiming success. Then run a complete task and read the completion certificate: it must name each required claim and the trace spans supporting it. Delete one supporting span and confirm completion is refused, not merely warned about. Finally replay the trace deterministically and check the claimed value reconstructs. If any of those three fails, your done is a feeling, not a verdict.
