Same English word, two authorities. + +`cxc.NOT_VERIFICATION` lists the facts that resemble verification and are not, each with the +reason it does not carry: + +- a `DONE` report, the child proving its own criteria rather than the parent's verdict +- an opened pull request, a place to review rather than a review +- a review `PASS`, one reviewer's judgment rather than the parent's disposition +- a green required check, evidence for a verdict rather than a verdict +- a completed turn, the trigger to look, as protocol v1 section 2 already says +- a dispatched delivery, neither an acknowledgement nor a verification + +## Review verdicts + +REVIEW-OUTPUT-01 fixes the final line, and this relay renders exactly that: `VERDICT: PASS`, +`VERDICT: GO-WITH-FIXES (blockers=N)`, `VERDICT: FAIL`. A `GO-WITH-FIXES` without a blocker +count is refused, because it is a `PASS` wearing a hedge, and a count attached to `PASS` or +`FAIL` is refused as a number nobody can act on. A verdict line is rendered only for a +message that carries a review, so an ordinary progress or completion notice cannot be +dressed as a review judgment. + +## Waiting + +LOOP-WAIT-EVIDENCE-01 keeps five endings apart, and `cxc.classify_wait` returns exactly one +of them: `progress`, `suspected_stagnation`, `confirmed_failure`, `unobservable`, +`input_needed`, and `timed_out` for a wait that simply ended on its bound. A terminal error +outranks everything; a request for input is not a failure; fresh advancing evidence outranks +the clock. No result ever sets `authorisesRerun`, because running the work again is a +decision somebody makes from evidence, and these are the states in which that evidence does +not exist yet. This mirrors what the delivery layer has always done: protocol v1 section 3 +says no delivery state is reachable by a timeout, and section 4 says elapsed time is not +affirmative evidence. + +## Instruction shape + +A revision request is an instruction, so it carries the DISPATCH-TASK-01 fields, `TASK`, +`SCOPE`, `MUST DO`, `MUST NOT`, `PROOF` and `RETURN FORMAT`, plus a decision boundary. It +leads with the criterion that was violated and the anchor that reproduces it, because a +correction whose first line is an identifier is a correction the child has to research +before it can start. The acknowledgement asymmetry is unchanged: contract v1 defines no +acknowledgement for the parent-to-child direction, so the message says so and tells the +child what does work instead. + +## What this does not do + +It builds no dispatch mechanism, no state machine and no provider retry ladder; CXC owns all +three. It adds no value to any frozen enum: not the receipt outcomes, not the delivery +states, not the verdict dispositions. It does not require the recovery daemon to run a CXC +cycle. And it neither reads nor depends on an installed CXC runtime at delivery time, since +the provenance record above is pinned data rather than a live lookup. diff --git a/packages/codex-session-relay/docs/invariants.md b/packages/codex-session-relay/docs/invariants.md index 618f874..2bcd421 100644 --- a/packages/codex-session-relay/docs/invariants.md +++ b/packages/codex-session-relay/docs/invariants.md @@ -101,6 +101,64 @@ status.
