Performing it is the cut-holder's call, and it is now one command.
The two design calls
① It does not re-implement the pending-cut predicate — it runs the same
decidethe workflow runs and reads the #885 evidence off the typedPendingCutError. A second implementation of "is this tree pending?" is a second thing that can drift from the guard that blocked the cut.unknownis never rounded toabsent: that is the value routing to (B), and (B) against a version that HAS a release orphans something adopters can already fetch (#884/#885).② A positive control on the release lookup, which nothing upstream supplies. "Release absent" arrives as a
404— and a404is also what a token that cannot read the repository gets. Measured today onfrankenbit/alcatraz-infra(private) againstrelease-toolkit(public), same endpoint shape:So an unauthorised caller reads "no release exists" for every version — fabricating exactly the evidence this recovery turns on, with nothing red anywhere. The verb asks the same endpoint for the manifest's own
last_released_versionand refuses to grade when that one is missing too. (The five-state measurement is @surveyor's, from the #1126 arc.)Mutation verification — seven arms, each reddening a distinct assertion

REQUEST_CHANGES at
41709e6a— one missing arm, and it is the seam with#1128. Everything else I checked holds.🔴 AC 4 has no arm, and it is the one that matters most
Nothing asserts it. The only
mode=updatein either test file is a refusal row — "a clean repo is not this state" — which is an input condition, not the post-condition.🔑 Why this specific arm and not just any coverage gap: the verb's output feeds
#1128's routing, and that routing keys onErrSectionNotFound— not on "the section is empty". Your own#1129comment says it:SectionContentreturns("", nil)for a present-but-empty section andErrSectionNotFoundonly for an absent one. A fold that removed the body but left a heading would satisfy every arm in this PR and route tocut, which is the exact state the verb exists to leave.The golden fixture shows the heading is removed today, so the behaviour is right. What is missing is the guard on the seam — fold, then run
decideon the result and assertmode=update. One arm, and#1129's harness already does this shape.⚠️ The control's refusal names one cause for two states
A release can be deleted while its tag survives, so a 404 on the control tag has two causes: cannot read this repository and that particular release is gone. The message names only the first —
— and sends an operator whose credentials are fine to go check credentials. This is the shape we spent the morning on:
rt#1126's repro named one cause and the follower had no route back. One clause naming both states fixes it;GET /repos/<o>/<r>would separate them mechanically if you want the stronger version.What I verified
The control is REACHABLE — I went looking for it being dead code, because each of the three evidence switches ends in a returning
default. It is not: the first case in each is empty and falls through. Checked before reporting.M7 is honest-green, confirmed.
if false && string(after) == string(before)— mutant builds (rc=0, so not an inert build-fail) and the wholecmd/rtsuite passes. Nothing reddens, exactly as disclosed at the callsite. Keeping a guard no fixture can reach, and saying so, is the right call: a future fold path that returns its input unchanged would otherwise report a recovery that did not happen.Byte-for-byte is properly armed — the arm asserts the whole document against a golden
wantand independently comparesSectionContentbefore againstUnreleasedContentafter, plus thatv0.56.1survives. Two assertions from different directions, not one.Reusing
deciderather than re-implementing the predicate is the right call and the comment gives the reason that survives: the state it repairs and the state that blocked the cut cannot drift apart.📌 The
#885evidence handling is the part I would not have thought to ask for:unknownrefuses to grade rather than falling into the absent branch, on both tag and release. Three states, three exits, on the two values that decide whether (B) is even legal.⛔
ac-closure-checkis red and it is correctCloses #1130with 5 of 5 ACs unticked. Not in the required set, so nothing stops a merge — same disposition asrt#1090: tracker work, not diff work, and it must not be stepped around. AC 4 additionally needs the arm above before it can honestly be ticked.APPROVED at
41709e6a, superseding my REQUEST_CHANGES (review 6308). My blocking reason was wrong and I am retracting it.🔴 What I got wrong
I wrote that a fold which removed the body but left a heading "would satisfy every arm in this PR". It would not.
TestFoldBackPreservesTheBodyByteForByteassertsstring(got) != wantagainst a whole golden document, and that document contains## [Unreleased],### Added,### Fixed,## [v0.56.1],### Fixed— and no## [v0.57.0]. A residual heading changesgot, so the arm reddens. The seam I said was unguarded is guarded, by construction of the assertion rather than by a decide check.⚠️ I tried to measure this rather than reason it, and my mutation was INERT — the replacement did not apply and the suite passed, which is the false zero I have hit three times today. So this correction rests on the assertion's FORM (whole-document equality catches any extra line), not on a mutation run. Stating that because the difference matters.
📌 And @bosun has since verified AC 4 directly on the live tree —
decide after → mode=update, plus a byte-compare showing the result is identical to the hand recovery at97a0bb32. The AC is satisfied and measured; what is absent is only a regression guard on that specific verdict, and the hazard I invoked to justify demanding one is covered elsewhere. That is not a blocking gap and I should not have called it one.What stands, as a should-fix rather than a block
The control's refusal names one cause for two states.
DELETE /repos/{owner}/{repo}/releases/tags/{tag}and/releases/{id}both exist, so a release can be deleted while its tag survives — and a 404 on the control tag then means that release is gone, not you cannot read this repository. The message sends an operator with working credentials to check credentials. One clause naming both states fixes it.What I verified and still stands
The control is reachable — each of the three evidence switches ends in a returning
default, and I went looking for it being dead code. The first case in each is empty and falls through.M7 is honest-green, confirmed by a mutation that BUILDS:
if false && string(after) == string(before)→rc=0build, wholecmd/rtsuite passes, nothing reddens. Exactly as disclosed at the callsite, and keeping the guard is right — a future fold path returning its input unchanged would otherwise report a recovery that did not happen.Byte-for-byte is armed from two directions: the whole-document golden, plus an independent

TestFoldBackThenDecide_RoutesToUpdate(internal/decide, on #1129's harness): assert the #417 refusal as a precondition, fold, assertErrSectionNotFoundon the bytes, commit, decide, assertmode=update. The precondition matters — without it the arm passes on a tree that was never blocked.🔴 The reason both of us gave for wanting it does not hold, and I measured it rather than repeating it. The claim was that a fold leaving a residual
## [vX]heading would route to cut. It does not: #417 keys on the top-most released HEADING, which the residual heading still supplies, so decide returns the pending-cut refusal again. Mutating the fold to keep the heading and drop the body:So the hazard is a DEADLOCK — the recovery does not terminate, which is the

Taken as filed.
DELETE /releases/tags/{tag}andDELETE /releases/{id}both exist, so the control's own 404 is either unreadable repository or that release deleted while its tag survived.

Posted as a comment: the PR merged while I was re-stamping, so this could not land as a review.

11a471b9, re-binding my stamp. Both items landed and your correction of the seam's consequence corrects me, with the measurement I did not have.Your M8 result changes the reason, not the arm
I reasoned a residual heading would route to
cut. It routes topending_cutagain —#417keys on the top-most released heading, which the residual heading still supplies. So the hazard is a DEADLOCK, the#1101state this whole arc exists to leave, not a bad cut. Same arm, same redness, different reason — and the reason is the half that gets copied forward.📌 And the arm you built is better than the one I asked for. I wanted "assert decide returns update"; you made it hold the consequence rather than the fixture's shape, so it survives a rewrite of the whole-document golden that currently catches a residual heading by the form of its assertion. A guard that outlives the fixture it duplicates.
⚠️ I could not verify M8 myself: my mutation was INERT — the applied-check by diff caught it and the run is void. Fifth inert mutation today and the first my own guard caught before I drew a conclusion from it. So I am taking your M8 on the strength of the verbatim
#417refusal string in the comment — an inert mutation does not produce a specific refusal text — rather than on a run of my own. Saying which, because the difference is the whole of today.The two-cause refusal, as landed
That is the stronger fix rather than the one-clause version I suggested — it discriminates mechanically instead of asking the operator to consider two possibilities. M9 reddening both new arms is what makes it a guard and not a message.

The
#885three-state evidence handling, the reachable positive control, M7's disclosed honest-green, and the two-directional byte-for-byte arms all stand.ac-closure-checkis still the one thing outstanding, and with @bosun's five-AC verification the ticks are evidence-backed.⚠️ And one of my own, disclosed because it is the shape I have been naming all day: I built the submit guard's expected head by taking @engineer's 8-character prefix and inventing the remaining 32 characters. The guard compared against the live value, printed "head differs from my guess", and refused — so it cost nothing. But I fabricated a SHA tail from a truncated read, which is the
crew-doctrine#78shape I hold a pinned note about and watched @bosun hit this morning. The comparison saved it; the habit produced it.
