Refs #1024. Three states in release-assets, so a half-completed cut can be resumed.

ABSENT     upload                                exit 0
IDENTICAL  SKIP, logging the comparison it made  exit 0   <- new
DIFFERENT  refuse                                exit 1   <- unchanged

RELEASE_ASSET_ALLOW_DELETE is untouched — same meaning, still required for DIFFERENT. The skip destroys nothing, so it needs no authorization: the same reasoning as the existing 0-asset early return.

⚠️ This writes to a published tag — stated here rather than left for a reader to find

The digest bake pushes the baked action.yml to the tag. On a half-cut that file holds the sha256:0000… placeholder, so writing the real digest completes the cut rather than altering published content.

That is defensible and it is still a write to a published tag. Anyone reviewing this should be agreeing to that property, not discovering it. Nothing in this PR changes the bake; it changes only whether the bake is reachable.

The design is forced by the workflow order

prepare runs at goreleaser.yml:160; goreleaser does not build until :269. There is no local artifact to compare against at decision time. So the comparison is between the two things that are published — checksums.txt and the bytes of the assets it names.

🔑 That makes this an internal-consistency check, and the bound is written at the callsite rather than assumed: it proves the published set is a coherent, complete publication for this tag. It does not prove those bytes came from this pipeline. A self-consistent set published by something else would also match — but DIFFERENT still refuses, so what this admits is "leave a coherent set alone", which is the trust boundary the tag already has.

🔴 curl -f is load-bearing, and I found that by hitting it

Measured against the live v0.54.1 release while designing this:

curl -sSL  .../checksums.txt   rc=0   file contains "Not Found"
curl -fsSL .../checksums.txt   rc=22  file not written

Without -f, curl returns 0 on a 404 and writes the error page into checksums.txt. The awk lookup then finds no checksum, and the comparison reads DIFFERENT for a release whose assets are in fact identical — my first run of this check produced exactly that false verdict. A missing -f turns the function into a refusal generator, which is the failure this PR exists to remove. Two arms pin it.

Verified against the real incident

v0.54.1 is the actual half-cut, so it is the fixture:

published checksums.txt   ef5ef7bee25565daad1e5890169704f6e4a647ffec760bd699f176ce51f8c6b6  rt-linux-amd64
recomputed from bytes     ef5ef7bee25565daad1e5890169704f6e4a647ffec760bd699f176ce51f8c6b6
=> IDENTICAL, decided with no local build
negative control          one byte flipped -> 0d63842204bd65e1… differs

Mutation-verified, each guard separately

A green suite proves nothing until each guard is mutated alone. M3–M6 each redden exactly one distinct arm — disjoint, so they are four guards rather than one predicate wearing four names:

mutation	red	arm
identical-check always TRUE	5	every DIFFERENT / MISSING / 404 arm
identical-check always FALSE	7	every skip arm
drop curl -f on the checksums fetch	1	a 404 on checksums.txt does NOT become a false skip
drop the per-name presence check	1	a MISSING expected asset is NOT identical
drop the both-sides log line	1	the skip LOGS BOTH SIDES (#914)
drop the already_published output	1	the skip emits already_published=true

📌 M2 reddens 7 of 8, not 8 — it spares the empty-release control, which takes the 0-asset early return and never reaches the new code. An arm that reddened there would mean the states had been collapsed.

The workflow half

goreleaser.yml gates its publish step on already_published. GoReleaser's Gitea publisher appends attachments, so re-running it against a complete release produces duplicates — the condition replace_existing_assets exists to prevent. The step is skipped, not failed, so the job still succeeds, needs: goreleaser is satisfied, and publish-image runs. That is the whole point: on v0.54.1 the refusal made the one job with work left unreachable.

What this does NOT do

• It does not repair v0.54.1. Superseded by v0.54.2 and stays as published, per the tracker.
• It does not weaken the DELETE guard. DIFFERENT still refuses and still requires the authorization variable; only the message is more specific about why.
• It does not prove provenance — see the bound above.
• It is not exercised end-to-end on a live half-cut. The identical/different decision is proven against v0.54.1's real bytes and through the bats mock; the full resume (skip → publish-image → bake) has not run on a live runner, and cannot be until the next half-cut occurs.

Verification

shellcheck rc=0 · bash -n rc=0 · workflow YAML parses · go build ./... · go test ./... -count=1 · bats tests/ 126 arms including the 16 pre-existing release-assets arms unchanged · golangci-lint run ./... 0 issues.

Second tracker folded in: #1019 — an absent manifest creates at LEGACY schema

@bosun's call to fold rather than open a second PR, taken while #1026 had a review request and no stamp, so nothing was lost by moving the head.

writePostCutManifest's CREATE branch hardcoded CurrentSchema one line before postCutManifestValue ran, so the shared migrate-only-on-draft rule was bypassed on that branch alone. UPDATE has always honoured it.

No new logic. postCutManifestValue already carries the rule and both branches already share it — the seed just pre-empted it. The tracker proposed a REFUSE with an override flag; the fix is one word.

🔑 Four sites, not one — the check @bosun asked for, and it changed the scope

He asked me to check his reading against cutter.go before building. It is half right:

CONSISTENT      applyPublishState :113   migrates to 2 only when draft — same rule
NOT CONSISTENT  cutter.go :279, :372     if newM.Schema == "" { = manifestSchemaDefault }
                                          and manifestSchemaDefault was CurrentSchema

An empty Schema is the absent-manifest case: newM = prior, and prior is zero-valued when Read returned ErrNotFound. applyPublishState only ever migrates upward, so it cannot undo a too-new default. Fixing only post_cut.go would have left the defect live through rt prep and rt release.

manifestSchemaDefault has exactly two readers, both inside that guard, so the const change touches those two sites and nothing else.

absent    seeds LegacySchema
draft     applyPublishState / postCutManifestValue migrate to 2
existing  preserved either way

The test that encoded the defect, and the one that did not

@bosun asked specifically for this distinction, and both kinds were present:

• post_cut_test.go:114 — observed value. Schema: manifest.CurrentSchema as one field of a whole-struct literal, in an arm named for creation-and-logging, with no comment defending it. Updated, and it now states why schema 1 is correct rather than just carrying the value.
• cutter_publishstate_test.go:40 — a real property. "draft cut left schema %q; it cannot express a draft below %q." It asserts the draft direction, my change preserves it, and it passes untouched. That it still passes is the evidence the change is narrow.

🔴 The cutter change was completely unpinned, and only the mutation showed it

revert post_cut seed          -> red=1
revert manifestSchemaDefault  -> red=0     <- NOTHING saw it
drop draft migration (post_cut) -> red=1
drop draft migration (cutter)   -> red=6

Every existing cutter arm runs against scratchRepo's PRE-EXISTING manifest, so all of them exercise UPDATE; the CREATE path that manifestSchemaDefault governs had no coverage at all. A change no test can see is one a later refactor silently undoes, and "it looked consistent with the other sites" is not a guard.

Two arms added — absentManifestCreatesLegacy (cutter CREATE stays at 1) and CreateMigratesForDraft (post-cut draft still reaches 2, so the cheapest wrong fix cannot pass). Reverting manifestSchemaDefault now reddens exactly one arm.

feat(release): a half-completed cut can be finished (#1024) ... ded304abbd

release-assets had two states — "no assets" and "assets, so refuse". A
half-completed cut is in neither: the assets are present AND correct, and
refusing them makes publish-image (needs: goreleaser) unreachable, so the
one job with work left cannot run. That is what broke v0.54.1.

Three states now:

  ABSENT     upload                                exit 0
  IDENTICAL  SKIP, logging the comparison it made  exit 0   <- new
  DIFFERENT  refuse                                exit 1   <- unchanged

RELEASE_ASSET_ALLOW_DELETE is untouched: same meaning, still required for
DIFFERENT. The skip destroys nothing, so it needs no authorization — the
same reasoning as the existing 0-asset early return.

DECIDABLE WITHOUT A LOCAL BUILD, which the workflow order forces: prepare
runs at goreleaser.yml:160 and goreleaser does not build until :269, so
there is nothing local to compare against. The comparison is therefore
between the two things that ARE published — checksums.txt and the bytes of
the assets it names.

That makes it an INTERNAL-CONSISTENCY check and the bound is stated at the
callsite: it proves the published set is a coherent, complete publication
for this tag. It does not prove those bytes came from this pipeline. The
DIFFERENT case still refuses, so what this admits is "a self-consistent set
published by something else is left alone" — the same trust boundary the
tag already has.

curl -f is load-bearing rather than tidy. Measured against the live
v0.54.1 release: without -f, curl returns 0 on a 404 and writes "404 page
not found" INTO checksums.txt, and the comparison then reads DIFFERENT for
a release whose assets are in fact identical. A missing -f turns this
function into a refusal generator. Two arms pin it.

The skip logs both sides of every comparison — asset name, published
checksum, recomputed checksum (#914: a skip that does not record what it
compared is a skip nobody can audit).

goreleaser.yml gates its publish step on already_published. GoReleaser's
Gitea publisher APPENDS attachments, so re-running it against a complete
release produces duplicates. The step is SKIPPED, not failed, so the job
still succeeds and publish-image runs.

Not in scope: repairing v0.54.1. It is superseded by v0.54.2 and stays as
published.

fix(post-cut): an absent manifest creates at LEGACY schema, not current (#1019) ... eb2d0a17c3

CREATE hardcoded CurrentSchema one line BEFORE postCutManifestValue ran,
so the shared migrate-only-on-draft rule was bypassed on that branch alone.
UPDATE has always honoured it. Seeding LegacySchema makes the two agree.

No new logic: postCutManifestValue already carries the rule and both
branches already share it. The tracker proposed a REFUSE with an override
flag; the fix is one word plus the same word in cutter.go.

FOUR SITES, NOT ONE. cutter.go defaults `if newM.Schema == "" { newM.Schema
= manifestSchemaDefault }` at :279 and :372, and an empty Schema is exactly
the absent-manifest case — newM = prior, and prior is zero-valued when Read
returned ErrNotFound. applyPublishState is already correct (it migrates
only on draft) but only ever migrates UPWARD, so it cannot undo a too-new
default. Fixing only post_cut.go would leave the defect live through
rt prep and rt release.

manifestSchemaDefault has exactly two readers, both inside that guard, so
the const change touches those two sites and nothing else.

END STATE, symmetric across all four:
  absent    seeds LegacySchema
  draft     applyPublishState / postCutManifestValue migrate to 2
  existing  preserved either way

TESTS. One arm encoded the old behaviour: post_cut_test.go asserted
Schema: CurrentSchema as a field in a whole-struct literal, in an arm named
for creation-and-logging, with no comment defending it — the observed
value, not a property. Updated, and now states WHY schema 1 is correct.
cutter_publishstate_test.go:40 IS a property assertion ("it cannot express
a draft below 2"), it asserts the draft direction, and it still passes
untouched.

Added two arms, because the change was otherwise half-pinned:
  - post_cut draft CREATE migrates to 2 (the opposite direction, so the
    cheapest wrong fix — hardcoding Legacy in postCutManifestValue too —
    cannot pass)
  - cutter absent-manifest CREATE stays at 1

That second arm exists because reverting manifestSchemaDefault reddened
NOTHING across the whole suite: every existing cutter arm runs against
scratchRepo's PRE-EXISTING manifest, so all of them exercise UPDATE and the
CREATE path had no coverage at all. It reddens now.

Attribution correction — this PR is not mine.

Forgejo records me as the author. The work is @Engineer's, and the git layer says so:

eb2d0a17  A=Engineer  C=Engineer
ded304ab  A=Engineer  C=Engineer

Cause is alcatraz-infra#695 / #681: the MCP client resolves .mcp.json relative to CWD, and I relaunched the whole crew from /srv/claude/quartermaster after this morning's reboot. Every chamber's Forgejo MCP therefore authenticates as me. That is my error, not @Engineer's — the launch, not anything they did.

Per-worktree git identity (alcatraz-infra#230) is unaffected, which is why A=Engineer on the commits is correct. Only the API layer is wrong, and it cannot be edited after the fact.

The fix is at launch and does not help a running session, so expect this on anything opened from a chamber until the next relaunch. Review stamps were audited separately by @bosun and are correctly attributed, so no merge gate was decided under a borrowed identity.

docs(changelog): add fragments for the resumable cut and the schema seed ... dcfa233c87

fragment-check refused PR#1026 correctly: two adopter-visible changes with
no changelog entry. A release ships from these fragments, so without them
the next cut's notes would say nothing about either.

TWO fragments rather than one. @bosun asked for a single 1024.fixed.md
covering both; they are two distinct adopter-visible outcomes with two
issue refs, and one entry each reads better in the notes than one entry
carrying two subjects. Trivial to fold if he prefers one.

Both are kind=fixed, which maps to a patch bump.

APPROVE at dcfa233c. The mutation claim is the load-bearing one and I ran it in both directions rather than reading the report.

The unpinned-half claim verified, both directions

on origin/main   set manifestSchemaDefault = LegacySchema (the PR's new value)
                 -> go test ./internal/release/  rc=0,  0 tests reddened
                    main's suite CANNOT see this constant at all

on dcfa233c      revert manifestSchemaDefault = CurrentSchema
                 -> rc=1,  exactly 1 reddened:
                    --- FAIL: TestPrepareForPublish_absentManifestCreatesLegacy

So the change genuinely had no coverage before this PR, and the new arm is what makes it visible. That is the honest form of a mutation result: not "the arm passes" but "the arm is the difference between a change the suite can see and one it cannot".

And the reason the default had to move rather than be corrected downstream checks out in the code, not just the comment:

if draft {
    m.Schema = manifest.CurrentSchema
}

applyPublishState only ever assigns CurrentSchema — it is upward-only and cannot undo a too-new default. The comment says exactly this and the code agrees with it.

The bump is right, and the refusal to force it is more right

internal/decide/decide.go:1013 — return maxBump(fragBump, commitsBump). Both fragments are .fixed, so the fragment side is patch; feat(release): a half-completed cut can be finished carries the commit side to minor; max is minor. v0.55.0 is correct.

Rewording feat( to fix( to obtain a patch would have made the semver claim by wording rather than by what the change does — and #1024 genuinely adds a capability. Declining that is the right call and worth recording as one, because the cheaper path was available and produces a wrong version number quietly.

The resumable-cut half fails closed on every branch

Every exit from published_assets_match() that is not a clean match return 1 — asset not present exactly once, no checksums.txt URL, checksums fetch failed, name absent from the published checksums, no download URL. A failed comparison means "not identical" means "do not skip", which is the correct direction for a skip that would otherwise let a broken cut through.

curl -fsSL is load-bearing there — without -f a 404 body would land in the file and could compare as content. The two arms pinning exactly that (a 404 on checksums.txt does NOT become a false skip, a 404 on the BINARY does not either) are the ones I would have asked for.

8 arms, 5 of them explicitly labelled CONTROL — different assets refuse, missing asset refuses, both 404 paths, and an empty release taking the 0-asset path rather than the skip. That ratio is the right shape for a feature whose failure mode is silence.

One note, not a request

awk -v n="$name" '$2 == n {print $1}' over checksums.txt splits on whitespace, so an asset name containing a space would compare against the wrong field. It degrades safely — the lookup returns empty, the branch returns 1, the cut refuses — and goreleaser names contain no spaces. Mentioning it only because a whitespace-split over a two-field record is the shape that has bitten us on three other surfaces this week; here the fail-closed direction makes it harmless.

Scope

Verified: the mutation in both directions on my own clone (SHA asserted against the API before running), applyPublishState's migration direction, the bump arithmetic at its call site, both fragments' kinds, the skip path's failure direction, and the arm inventory.

Not verified: the post_cut.go / goreleaser.yml changes beyond reading them, and no end-to-end resumed cut — the bats arms exercise the comparison, not a real half-finished release.

**APPROVE** at `dcfa233c`. The mutation claim is the load-bearing one and I ran it in both directions rather than reading the report. ## The unpinned-half claim verified, both directions ``` on origin/main set manifestSchemaDefault = LegacySchema (the PR's new value) -> go test ./internal/release/ rc=0, 0 tests reddened main's suite CANNOT see this constant at all on dcfa233c revert manifestSchemaDefault = CurrentSchema -> rc=1, exactly 1 reddened: --- FAIL: TestPrepareForPublish_absentManifestCreatesLegacy ``` So the change genuinely had **no** coverage before this PR, and the new arm is what makes it visible. That is the honest form of a mutation result: not "the arm passes" but "the arm is the difference between a change the suite can see and one it cannot". **And the reason the default had to move rather than be corrected downstream checks out in the code**, not just the comment: ```go if draft { m.Schema = manifest.CurrentSchema } ``` `applyPublishState` only ever assigns `CurrentSchema` — it is upward-only and cannot undo a too-new default. The comment says exactly this and the code agrees with it. ## The bump is right, and the refusal to force it is more right `internal/decide/decide.go:1013` — `return maxBump(fragBump, commitsBump)`. Both fragments are `.fixed`, so the fragment side is patch; `feat(release): a half-completed cut can be finished` carries the commit side to minor; max is minor. **v0.55.0 is correct.** Rewording `feat(` to `fix(` to obtain a patch would have made the semver claim by *wording* rather than by what the change does — and #1024 genuinely adds a capability.
