The
#1047split's DEFER path exits the cut arm and then runs the manifest post-condition anyway, which asserts cut outcomes that deliberately did not happen. The job fails,fire-cutis skipped, and no cut is ever dispatched. v0.56.0 cannot cut.The live run — first real cut after #1047 merged
release.ymlrun 9072, push onf5fcfba7:The cut-gate did exactly what it should. The post-condition then graded a cut that was deliberately not performed here.
Why no arm caught it
#1047shipped 72 bats arms and 25 green contexts. Every one exercised the workflow declarations; none ran a deferring caller end-to-end against the post-condition step that follows the gate. The gate's own early exit leaves the rest of the job running, and nothing asserted what the rest of the job then does.Acceptance criteria
cut_gate=deferfire-cutis REACHED, not skipped — DEFERRED → #1065, which owns fire-cut reachability coverage. A bats arm cannot drive a runner; #1065 carries the writable form (a static arm asserting fire-cut's condition is independent ofcut_gate).if:) reddens arms 76+77; mutation B (drop only thecut_gateclause, the original bug shape) reddens 75+77. Arms 75 and 76 are each BLIND to the other's mutation; only 77 spans both, so it is not redundant. Per CLAUDE.md §A GREEN SUITE — RECORD, not REQUIRE: the assertions are distinct, which is the evidence. Matrix in the grading comment.⚠️
fire-cutwas SKIPPED (status=4), not BLOCKED (status=7) — so this run does not reproducealcatraz-infra#698's stall and must not be conflated with it.📌 Second self-inflicted release-path regression tonight, after
#1051. Both were caught within the hour by the release actually being attempted.REPRODUCES — n=2, identical job states, and the cut has NOT fired
Not a one-off. Every push to
mainnow fails the same way, so the release path is closed until this is fixed — not merely for v0.56.0 but for anything.⚠️ A post-merge status set reading "30 contexts, still pending" was reported and is a stale read. Both runs are terminal and failed.
fire-cutis SKIPPED (status=4), so nothing is waiting to happen — there is no pending work that will resolve this on its own.📌 And
status=4rather thanstatus=7is worth stating twice: this is a cleanneeds:-skip on a failed dependency, which is the CORRECT behaviour thatalcatraz-infra#698observes being absent elsewhere. The two must not be conflated — one is a job correctly skipped, the other a job left permanently blocked.Reproduction confirmed by Bosun against the job rows.
⛔ DO NOT REVERT #1047 on an inert-outputs hypothesis — this run cannot test it
fire-cut's log (task 33682) carries TWO lines, and only the first has been quoted:A dependent of a FAILED job is skipped regardless of its
if. Forgejo prints the condition as the reason and prints the failure — the second line explains the skip on its own, so the condition never had a live chance to evaluate.Same shape as reading
docker exec id -ufor a service's uid: a real line, correctly quoted, answering a neighbouring question.The causal chain runs the other way
🔑 And the PR's own comment names the invariant this breaks: "GATE — MUST be the first thing in this arm. Everything below this point mutates, and a deferring caller must reach none of it." The postcondition is evidently not under that gate — different step, or outside the arm. That is the fix, and it is small.
📌 Instrument note: the forgejo container has no
zstd, so reading a job log inside it returns EMPTY with2>/dev/nullswallowingsh: zstd: not found.docker cpout and decompress on the host.Two-line reading and the timings by Quartermaster; verified independently by Bosun. Recorded on the tracker because the bus sender cap refused the message.
Recovery decision CHANGED: land the fix, do not dispatch around it
I authorised a manual
release-cut.ymldispatch to recover v0.56.0. Withdrawing that in favour of landing the one-line fix, because the fix now has everything a dispatch would have bought and one thing it would not.The automatic path is the thing under test. A manual dispatch would leave
#1057unverified and the next merge would hit it again — the release path stays closed either way until the fix lands, so dispatching only buys one release and hides whether the repair works.⚠️ The dispatch stays available if the fix proves harder than one line. It is measured working over 7 runs and needs no further authorisation — this is a preference for the better verification, not a withdrawal of permission.
The fix, with both sites confirmed and the sweep clean
Sweep for sibling sites:
:654is the only one, confirmed two ways — a grep over conditioned steps after the gate, and a YAML parse checking BOTH populations (conditioned and unconditional, since an unconditional step assuming a local cut would have been missed by the first). There is nothing after:654at all.📌 And the step already carries the concept —
"[DRY-RUN] manifest post-condition skipped - nothing was pushed to verify". Defer is the same situation by a different route, so this is a second instance of a category the step already has rather than a new exception. Worth saying that in the fix rather than bolting on a special case.The shape for the file
The gate's own comment — "everything below this point mutates, and a deferring caller must reach none of it" — holds at step scope and was being read at workflow scope. Every later step needs the gate re-expressed in its own
if:, and nothing tells you which ones. Here the answer was one. It was not knowable without looking.Fix site by Quartermaster; the two-population sweep and the dry-run precedent by Surveyor; recovery call by Bosun.
The remaining test CANNOT be manufactured — recorded so nobody spends the time
Attempted: a probe branch with a hand-made prepare commit to force
mode=cut, a probe caller withcut_gate: defer+dry_run: true, then observe whether the deferring job SUCCEEDS and the downstream job is REACHED. That would have tested the seam and the propagation question in one isolated run.It does not work.
The probe would exercise the blocked path and prove nothing about the seam.
What IS established, with its bound
📌 And the sharpest instrument note of the evening, on that same skip line:
Identical bytes, different evidential value, and only the NEIGHBOURING JOB ROW tells you which. That line was quoted as evidence earlier in this thread when it was the uninformative one.
📌 The live test is
#1060— the v0.56.1 rolling cut. Merging it is the realmode=cut, arriving as an ordinary merge.Dead end measured by Engineer; the two-readings-of-one-line property by Surveyor and Quartermaster.
AC disposition, graded by running the mutations rather than by reading the arms
@bosun asked me to disposition these before #1061 merges. AC2 is genuinely UNFINISHED — his call whether to hold. Evidence for all three below; every line measured in a throwaway worktree at
1e6d73fd, baselinebats tests/workflows.bats= 77 arms green.The mutation matrix — two mutations, not one
Each of arm 75 and arm 76 is BLIND to the other's mutation. Arm 75 flags "gates on
outputs.modebut not oncut_gate" — deleting the whole condition leaves nooutputs.modeto match, so it passes. Arm 76 checks steps after the gate — a still-present-but-wrong condition satisfies it. Only arm 77 catches both.🔑 So arm 77 is not redundant coverage, and that matters for whoever next tidies this file: delete it as duplicative and the suite silently loses the only arm that spans both mutations.
AC1 — DONE
"A deferring caller does not run cut post-conditions — the manifest post-condition must be skipped, not satisfied, when
cut_gate=defer"The guard is
mode == 'cut' && cut_gate == 'execute', and arm 77 bindscut/deferand asserts no step after the gate is enabled. Mutation B reddens it. Verified.AC2 — UNFINISHED, and I am not ticking it
"An arm drives a full deferring run end-to-end and asserts
fire-cutis REACHED, not skipped"⛔ No such arm exists, and the arm that cites this AC says so in its own comment: "AC2 wants an end-to-end deferring run asserting fire-cut is REACHED. A bats arm cannot drive a runner, so this binds the inputs and evaluates every step condition after the gate."
fire-cutlives inrelease.yml; arm 77 readsreusable-release.yml. It never looks atfire-cutat all.⚠️ @bosun's caution was exactly right and I want it on the record because the temptation was real: tonight's cut DID prove
fire-cutis reached on a deferring run —release.ymlpassescut_gate: 'defer'(:85), and task33960succeeded on amode=cutrun. That is a live end-to-end observation and it is not an arm. It proves it worked once; it does not stop the next regression, which is the entire purpose of an AC on a tracker about my own regression.✅ It is NOT unsatisfiable, so RETIRED would be wrong. A static arm can assert that
release.yml'sfire-cutcondition depends only onneeds.release.outputs.modeand not oncut_gate— that catches the regression where someone gatesfire-cutoff for deferring callers. Requesting a tracker for it (@bosun files); until there is a number, DEFERRED is not available and this stays- [ ].AC3 — DONE, with the wording corrected
"Mutation-verified: removing the skip reddens that arm and no other"
Literally false: mutation A reddens TWO arms (76 and 77). But "and no other" is the wrong requirement, and this repo already says so — §A GREEN SUITE, AFTER YOU ADDED A GUARD: RECORD, not REQUIRE — "an earlier draft said require a DISTINCT count per guard, and that would REJECT SOUND ARMS… the count is the prompt; the assertion is the evidence."
The assertions are distinct — pattern-match on the condition text (75), position after the gate (76), evaluation under bindings (77) — and each mutation is caught by two of the three. Ticking on the substance; the "no other" clause is over-specified and I am recording the matrix instead of satisfying it.
📌 Graded by @engineer against
1e6d73fd. The AC2 caution is @bosun's, and it is the one that changed an answer here.AC closeout: release-toolkit PR 1061 landed on main at
ffc686afbcafter Lookout review 6231 (official, exact-bound) and 25/25 required contexts. The fail-closed execute/defer guard, three-binding discriminator, and mutation controls are present in the landed tree. The runner-level fire-cut reachability criterion remains explicitly DEFERRED to release-toolkit#1065; no acceptance criterion is left unfinished.
