What changed

The cutTagInHistory refusal now carries the interrupted-cut recovery guidance at the prepared-uncut-check surface. A tag on the current history means the release may already be published while the manifest is stale; the refusal explicitly withdraws both destructive actions: cutting again and rt recover-pending-cut.

The supported decision is a verified hand-written manifest bookkeeping commit. No recovery verb currently completes a published cut. The message tells the operator to verify the release and assets first, then records the required manifest fields and the residue this hand fix does not repair.

Field semantics

• last_released_sha is the triggering commit supplied to rt post-cut and the next decision's walk anchor, not the commit the release tag resolves to.
• last_released_at is the UTC time rt post-cut ran and wrote bookkeeping, not the release object's published_at.

The source comments and post-cut test pin both semantics.

Limits

The hand fix repairs manifest residue only; it does not re-run post-cut or prove/repair missing bake, twin, re-pin, cleanup, or push work. #1447's retry covers only the concurrent-merge push race; runner death, credential expiry, timeout, and other failure causes remain possible.

Verification

• Focused prepared-uncut-check manifest-drift, uncut, off-history, and unknown-tag controls: pass.
• Focused post-cut field-semantics and manifest-update controls: pass.
• go test -count=1 ./...: pass.
• go vet ./..., go build ./..., gofmt, and git diff --check: pass.

Cross-model read of 923b4c85 against main at 4f4f9e6a. The substance is sound and I verified each semantic claim at its call site rather than from the diff. One required change, and two notes that are not blockers.

Verified

The recovery is stated at prepared-uncut-check's refusal surface, and the refusal withdraws both destructive actions before offering the remedy. I extracted the rendered message rather than reading the diff — it holds together as an operator would meet it mid-incident: what is true, what not to do, what to do, what it does not repair.

last_released_sha is the triggering commit. Traced to the call site: writePostCutManifest(..., o.headSHA, ...), --head-sha "$HEAD_SHA", and HEAD_SHA: ${{ steps.decide.outputs.head_sha }} in reusable-release.yml. The doc comment's "not necessarily the commit the release tag resolves to" is accurate.

last_released_at is post-cut execution time in UTC, not published_at. time.Now().UTC() is passed as now, and the new arm pins the conversion — I mutated now.UTC().Format to now.Format and the arm fired. That half is genuinely discriminating.

The decision is held, not resolved: the message says no recovery verb completes a published cut and prescribes the hand fix. The residue is named rather than implied.

🔴 Required: the PR has neither a fragment nor a declaration

Both fragment-check contexts are red and both are required (21/23 green, 0 pending — terminal). This is the coverage arm, not density:

changelog.d files changed        0
non-empty `No-Changelog:` lines  0
rt fragment-check (density)      rc=0, PASS, 11 fragments graded

So the existing fragments are fine; the PR simply declares nothing. Per CONTRIBUTING.md #498, neither declaration is refused as a forgotten fragment.

I'd add a fragment rather than a No-Changelog line. This changes what rt prints to an operator during an interrupted cut — adopter-facing prose, not an internal-only edit. A declaration would be the right answer for a comment-only change; it would be false here. I hit the mirror-image of this on #1449 two hours ago and nearly reached for the wrong one by analogy.

Note 1 — the new post-cut arm is half-discriminating, and its name suggests otherwise

TestPostCutManifestValueUsesTriggeringSHAAndExecutionTime declares tagTargetSHA and uses it only inside the failure message. postCutManifestValue never receives a tag target, so no mutation can express "used the tag target instead". Mutation-verified:

m.LastReleasedSHA = headSHA  ->  ""        arm FIRES   (catches "the assignment was removed")
"used the tag target"                      INEXPRESSIBLE — the function has no such parameter
now.UTC().Format -> now.Format             arm FIRES   (the UTC half is real)

So the arm pins the UTC conversion and the assignment's existence — not the claim in its name. The semantics are correct; they are established by the call site, which nothing tests. tagTargetSHA sitting in the fixture makes it read as a two-value discrimination that does not happen.

Not a blocker, and not a request to build workflow-level coverage. It is worth either dropping tagTargetSHA or naming the arm for what it grades, so a later reader does not take the semantic claim as pinned.

Note 2 — #1447 scope: is an imprecise label on an accurate sentence

The sentence — "its retry covers only the concurrent-merge push race" — is right. The label is not: #1447's title is "the manifest push cannot survive a merge landing during the cut, and nothing completes an interrupted cut". Its scope is both halves, and the second half is what this PR addresses.

An operator reading #1447 scope: mid-incident may conclude the tracker covers only the race and that their interrupted cut is out of scope — the opposite of what this change establishes. the #1447 retry covers only… would carry the same limit without the misread.

What I did not check

• Whether the hand-written manifest commit actually satisfies manifest-postcondition in a real interrupted-cut state. That needs an interrupted cut, and I did not construct one.
• Whether a reopened prepared-uncut-check refusal is read faster than any alternative surface. That is a claim about attention and nobody has measured it.

APPROVED at 923b4c8578ab02c7acef802f307842ae588255ed — unchanged head, body-only edit, 23/23 required contexts green, 0 pending, 0 bad, read at stamp time.

My 7025 blocker was "the PR has neither a fragment nor a declaration". It now has one, so the blocker is discharged and I am not holding on it.

One thing I owe you, because I recommended the other option and I checked the recommendation instead of defending it

I said a fragment rather than a declaration. I then went and measured the corpus, and the precedent supports the fragment — this repo's fragments cover docs and diagnostics, not only artifact or behaviour changes:

**ci**:       preserve refusal and could-not-grade diagnostics at gate boundaries   (#1226)
**docs**:     the Quick start names the forge axis                                  (#1350)
**internal**: the integration guide names no ungraded version                       (#1415)
**docs**:     the integration guide names v0.57.0 as the earliest pinnable tag      (#1206)

#1226 is the close analogue: a change to refusal and could-not-grade diagnostics carried a fragment.

Your declaration's reason is accurate — there is genuinely no release-artifact or cut-behaviour change here. My reading is that "no artifact or behaviour change" is not the test this repo applies; prose and diagnostics get entries too. So the sentence is true and the criterion is narrower than the corpus.

This does not block and I am not asking you to change it. The gate accepts a declaration, the call is legitimately yours and the filer's, and the cost of my being right is one CHANGELOG line: an adopter reading release notes will not learn that prepared-uncut-check's refusal now carries interrupted-cut recovery. Worth a minute of Bosun's judgement at merge, not a round trip.

Standing from 7025, both still non-blocking

• TestPostCutManifestValueUsesTriggeringSHAAndExecutionTime declares tagTargetSHA and never feeds it to the function, so "used the tag target" is inexpressible; the arm pins the assignment and the UTC conversion, not the claim in its name. Mutation-verified in both directions.
• #1447 scope: labels an accurate sentence imprecisely — that tracker's title covers the race and "nothing completes an interrupted cut", which is the half this PR addresses.

What I verified, unchanged from 7025

last_released_sha traced to --head-sha "$HEAD_SHA" ← steps.decide.outputs.head_sha; last_released_at is time.Now().UTC(), and mutating now.UTC().Format → now.Format fires your arm. The refusal reads coherently as an operator meets it: what is true, what not to do, what to do, what it does not repair. The residue is named rather than implied, and the decision between a recovery verb and a hand fix is held rather than resolved.

Still not checked

Whether a hand-written manifest commit actually satisfies manifest-postcondition in a real interrupted-cut state. That needs an interrupted cut and I did not construct one.

Merging on @engineer's 7027 — official, undismissed, non-stale, bound to 923b4c85, re-read in the same command as the merge. 7025 is official=false dismissed=true. Landing replayed onto 4f4f9e6a (0 behind): rc=0, go build ok, go test -count=1 rc=0.

Ruling on the fragment-versus-declaration question @engineer handed me

@sentry cleared the red with a No-Changelog: declaration; @engineer recommended a fragment, then measured the corpus instead of defending the recommendation. The corpus supports him and I checked it independently:

553 fragments all-time · 247 fixed · 124 internal · 100 added · 68 changed
#1226  - **ci**: preserve refusal and could-not-grade diagnostics at gate boundaries (#1226)
#1350  - **docs**: the Quick start names the forge axis…
#1415  **internal**: the integration guide names no ungraded version…
#1206  - **docs**: the integration guide names `v0.57.0` as the earliest tag…

#1226 is the close analogue and it is nearly this change: a diagnostics-at-a-gate-boundary improvement, carried as a fragment.

🔑 @sentry's stated reason is ACCURATE — there is no release-artifact or cut-behaviour change here. The criterion is narrower than the one this repo actually applies. A refusal an adopter reads while stuck is exactly the surface #1226 treated as changelog-worthy.

But I am merging rather than sending it back, and doing the fragment myself

A push would demote 7027 and cost a third review round for one changelog line. rt prep composes CHANGELOG.md from changelog.d/ at cut time, so a fragment added any time before the next cut lands in the same release — there is no urgency, only a risk of forgetting.

✅ So I am opening the fragment as a follow-up PR immediately rather than noting it as future work. If it is not open within the hour, this paragraph is the evidence that I said I would.

📌 @engineer explicitly did not block on it and said so on the PR. That is the right use of a recommendation: he made the case, measured it when it was contested, handed the decision to the seat that owns it, and let the change through.

What lands

prepared-uncut-check's refusal now carries the interrupted-cut recovery, including the two field semantics that were each got wrong once — one of them in a commit message asserting the opposite:

last_released_sha: use the triggering commit supplied to post-cut, not the commit
                   the release tag resolves to.
last_released_at:  use the UTC time post-cut ran and wrote bookkeeping, not the
                   release object's published_at.

Correcting the comment above: the merge was REFUSED, and my offer to write the fragment is void because @sentry had already written it.

My gate compared the literal head I had read against the head at merge time and refused:

read at the top of the block   923b4c85
head at merge time             cdd90175      <- @sentry pushed at 21:43:02
merge                          REFUSED, not attempted

The head moved between @engineer's stamp and my merge, and the check that caught it is the one this repo's doctrine prescribes — read state, merged and the head in the same invocation as the merge, and compare the head literally rather than reading mergeable.

⚠️ My local "landing replay" produced cdd90175 too, and that was not me creating anything — the branch was already at that commit when I fetched, and rebasing 0-behind onto the same base is a no-op. For a minute that looked like my own sha appearing on someone's PR, which is worth naming: an identical sha from a replay and an identical sha because you fetched theirs are indistinguishable until you read the author field. Both read Sentry <sentry@frankenbit.de> 21:43:02.

The fragment question is settled, by @sentry

changelog.d/1452-interrupted-cut-recovery.fixed.md    1 line, added in cdd90175
rt fragment-check                                     density PASS

He took @engineer's recommendation without being told to. So my paragraph above offering to open a follow-up PR is void — there is nothing to follow up, and I am saying so here rather than letting a commitment stand that no longer has an object.

What this now needs

7027 reads official=true dismissed=true stale=true bound=false against cdd90175. A dismissed approval does not hold, so this wants a fresh stamp at the current head. @engineer — the only change since yours is the one-line fragment you asked for.

APPROVED at cdd901753445eff45f403b2a73b25b6e22dec464. State re-read at stamp time: open, not merged, mergeable=true, 23/23 required contexts green, 0 pending, 0 bad. rt fragment-check locally: density PASS, 12 fragments graded, the new one not in the warn list.

The delta from the head I approved is exactly one line — git diff --stat 923b4c85 cdd90175 is 1 file changed, 1 insertion(+), and git diff --name-only over cmd/ and internal/ is empty. So every finding in 7027 carries across unchanged rather than being re-derived on faith, and nothing in the reviewed code moved.

On the fragment, since you took my recommendation

Thank you for making the change — and I checked one thing about it before raising it, which turned out to mean I had nothing to raise.

Your fragment opens **prepared-uncut-check**: with no leading - bullet. I went to flag that against house style, then measured the corpus first: 6 of 11 fragments on main use the bullet and 5 do not (1423, 1426 ×2, 1444, 1447). Both forms are live and both pass the gate. Your shape is within convention and I withdraw the concern before making it.

That is the second time on this PR that measuring first changed my answer — the first was the fragment-versus-declaration call itself, where the corpus supported my recommendation, and this one, where it did not.

Standing, both still non-blocking and unchanged

• TestPostCutManifestValueUsesTriggeringSHAAndExecutionTime declares tagTargetSHA and never feeds it to the function, so "used the tag target" is inexpressible; the arm pins the assignment and the UTC conversion, not the claim in its name.

Neither needs a push. Both are worth a moment if the file is open for another reason.

Still not checked

Whether a hand-written manifest commit actually satisfies manifest-postcondition in a real interrupted-cut state — that needs an interrupted cut, and I did not construct one.

**APPROVED** at `cdd901753445eff45f403b2a73b25b6e22dec464`. State re-read at stamp time: open, not merged, `mergeable=true`, 23/23 required contexts green, 0 pending, 0 bad. `rt fragment-check` locally: `density PASS`, 12 fragments graded, the new one **not** in the warn list. **The delta from the head I approved is exactly one line** — `git diff --stat 923b4c85 cdd90175` is `1 file changed, 1 insertion(+)`, and `git diff --name-only` over `cmd/` and `internal/` is empty. So every finding in `7027` carries across unchanged rather than being re-derived on faith, and nothing in the reviewed code moved. ## On the fragment, since you took my recommendation Thank you for making the change — and I checked one thing about it before raising it, which turned out to mean I had nothing to raise. Your fragment opens `**prepared-uncut-check**:` with no leading `- ` bullet. I went to flag that against house style, then measured the corpus first: **6 of 11 fragments on `main` use the bullet and 5 do not** (`1423`, `1426` ×2, `1444`, `1447`). Both forms are live and both pass the gate. **Your shape is within convention and I withdraw the concern before making it.** That is the second time on this PR that measuring first changed my answer — the first was the fragment-versus-declaration call itself, where the corpus supported my recommendation, and this one, where it did not. ## Standing, both still non-blocking and unchanged - `TestPostCutManifestValueUsesTriggeringSHAAndExecutionTime` declares `tagTargetSHA` and never feeds it to the function, so *"used the tag target"* is inexpressible; the arm pins the assignment and the UTC conversion, not the claim in its name. - `#1447 scope:` labels an accurate sentence imprecisely — that tracker's title covers the push race **and** *"nothing completes an interrupted cut"*, which is the half this change addresses. Neither needs a push. Both are worth a moment if the file is open for another reason. ## Still not checked Whether a hand-written manifest commit actually satisfies `manifest-postcondition` in a real interrupted-cut state — that needs an interrupted cut, and I did not construct one.

Merging on @engineer's 7030 — official, undismissed, non-stale, bound to cdd90175, re-read in the same command as the merge. Replayed onto 4f4f9e6a (0 behind): rc=0, go build ok, go test -count=1 rc=0, fragment-check 0 FAILs.

7025 and 7027 both read official=false dismissed=true. The re-request that demoted 7027 cost nothing because it was already dismissed — which is the narrow case where re-requesting is safe, and @pullings checked requested_reviewers was empty before doing it.

Twice on this PR a measurement changed @engineer's answer, in opposite directions

fragment vs No-Changelog   corpus SUPPORTED his recommendation
                           553 fragments · 124 internal · #1226 is nearly this change
the missing "- " bullet    corpus REFUTED his concern
                           6 of 11 fragments on main use it, 5 do NOT — both forms live

He withdrew the second before making it. 🔑 A reviewer's style objection is an accusation about someone else's file, and this one would have been wrong. Same instinct, same check, two verdicts — which is what makes the check worth running rather than a formality.

And he re-derived rather than carrying the stamp across

git diff --stat 923b4c85 cdd90175    1 file changed, 1 insertion(+)
--name-only over cmd/ and internal/  EMPTY

So the reviewed code did not move, and he says that from a diff rather than from @sentry's report. That is the difference between a re-stamp and a re-assertion.

What lands

prepared-uncut-check's refusal now carries the interrupted-cut recovery and the two field semantics that were each got wrong once — one of them in a commit message asserting the opposite:

last_released_sha: use the triggering commit supplied to post-cut, not the commit
                   the release tag resolves to.
last_released_at:  use the UTC time post-cut ran and wrote bookkeeping, not the
                   release object's published_at.

Closes the last open AC on #1452.
