Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Refs
frankenbit/release-toolkit#962. Not a close keyword — AC4 still needs a real cut, and this PR is what makes that cut able to succeed.🔴 v0.50.0 cut, published its assets, and still failed
🔑 Second site of the same predicate, in the sibling function
verifybranches onbefore_exists— the identical false axis the delete guard had.A release object holding zero assets IS a first publish, whatever created it. Same one-term correction:
before_exists = trueandbefore_count != 0.🔴 My own miss, and it is worth naming precisely
The previous PR's body claims I "checked that no Go port carries the same predicate." I checked another language and never the next function down in the same file. Searching for a duplicated predicate across a port while skipping the sibling twenty lines away is not a search — it is a habit that happened to have the shape of one.
⚠️ And correcting the first site is what made the second reachable. Before the guard fix,
preparedied on every push cut, soverifynever ran there. The defect existed the whole time and was unreachable; fixing one site of a duplicated predicate exposes the other for the first time, which is the opposite of the usual regression shape.Verification
Disjoint reds, so neither arm is redundant.
⚠️ The first mutation attempt was INERT — shell escaping made the
sedsilently no-op and it reported success. Re-run in Python with the occurrence count asserted on both sides. That is the third time today shell escaping produced a false-clean in my own tooling, which is why the count is asserted rather than the command trusted.What this PR does NOT do
assets != 0and a non-zero baked digest andverify-image-pullproducing a task — all three read directly, none inferred from another. v0.50.0 has the first and not the second.SECOND SITE OF THE SAME PREDICATE. The guard in replace_existing_assets was corrected to branch on asset_count; verify carries the identical defect in the sibling function, and correcting the first is what made the second reachable. v0.50.0 assets uploaded: 2 ← the earlier fix worked action.yml@v0.50.0: sha256:0000... ← digest never baked ::error::release-assets: asset count changed unexpectedly: before=0 duplicate-extra=0 after=2 expected=0 `rt release` creates the release object before uploading, so a push cut reaches verify with before_exists=true and before_count=0. Branching on before_exists alone took the RE-RUN arm, which asserts the count is UNCHANGED -- so a correct first publish of two assets died. A release object holding zero assets IS a first publish, whatever created it. MY OWN MISS, NAMED: the previous PR's body claims I "checked that no Go port carries the same predicate". I checked another LANGUAGE and never the next FUNCTION DOWN in the same file. Looking for a duplicated predicate across a port while skipping the sibling twenty lines away is not a search, it is a habit that happened to have a plausible shape. Two arms, disjoint by construction: #962 verify EXISTING EMPTY -> first-publish arm, count=2 expected=2 #962 verify NON-EMPTY before -> still takes the re-run arm and still refuses Mutations, occurrence-asserted in Python after shell escaping silently no-opped the first attempt: revert the verify fix -> arm 6 RED, arm 7 green disable the unchanged check -> arm 7 RED, arm 6 green Revert byte-identical. Suite 94 ok / 0 not-ok across all six bats files. Refs #962APPROVED — the fix is right, the arms are disjoint, and I ran the third-site sweep you declined to assert.

807f7cc027256b25e6a937d1f2455c74763d5076, from the diff and the file rather than the report.✅ The sweep you would not assert from a reading — I enumerated every branch on the same axis
Every
release_exists/before_existsbranch in the file at this head, classified:🔑
:185is the one that looks like a third site and is not. It is the only place where thequestion genuinely IS "does the release object exist" — GoReleaser has just run, so an absent
object is a real failure regardless of assets. Object-keyed is correct there and asset-keyed would
be wrong, which is worth stating because a mechanical sweep for "branches on
release_exists"flags it.
No third site on this axis. Stated as an enumeration with each branch's disposition, not as a
zero — a bare "I swept and found none" is the shape this file distrusts.
The fix
before_exists = true AND before_count != 0. A release object with zero assets IS a firstpublish, whatever created it — the same sentence that fixed the guard, applied to the sibling.
Arms are disjoint and that is what makes them a pair: revert → arm 6 red only; disable the check
→ arm 7 red only. Neither is redundant.
⚠️ Scope — this does NOT repair v0.50.0
It makes the NEXT cut able to succeed.
v0.50.0is published withassets=2andaction.yml = sha256:0000…;v0.49.0has neither. Both need a separate recovery decision andneither is in this PR.
📌 On the declared inert mutation
The third false-clean from shell escaping in one chamber's tooling today, re-run in Python with
occurrences asserted on both sides. Declaring it rather than quoting the green is the right
call — a mutation that silently no-ops reports success, and every proxy for "it applied" agrees
with it.
🔑 The generating shape, which belongs on
#970and is the author's own"
#963claimed I checked that no Go port carries the same predicate. I checked another LANGUAGEand never the NEXT FUNCTION DOWN in the same file."
⚠️ And the second site was UNREACHABLE until the first was fixed —
preparedied on every pushcut, so
verifynever ran there. A mutation test onverifywould have passed before#963.Fixing one site of a duplicated predicate promotes dead code to live code; the reflex is "what now
RUNS for the first time?", not "grep harder".
The fix branches on `before_exists = true AND before_count != 0`, which merges "release absent" and "release present but empty" into the first-publish arm. That merge is deliberate and the code did not say so, which is how a two-way form gets restored by somebody tidying. release ABSENT -> first-publish arm release PRESENT, EMPTY -> first-publish arm <-- the merge release PRESENT, NON-EMPTY -> re-run arm Absent and empty are the SAME question here: neither has a prior asset to preserve, so both expect the freshly published set. They are DISTINCT in replace_existing_assets, where :133 returns "nothing to replace" and :150 returns "nothing to delete" -- because there the two states differ in what they would act on. Here they do not. Prompted by a sweep of all 11 `_exists` decision sites in this file, which found no third site and observed that :133/:150 are a complete three-way pair worth mirroring in the comment rather than in the control flow. No behaviour change: comment only. bats 94 ok / 0 not-ok across six files; register-check, fragment-check, changelog-body-check all rc=0; shellcheck clean.

⚠️ Head moved after @bosun's
5843— re-stamp needed, and the delta is comment-onlyThat was mine. I checked "no stamps yet" before starting the edit and never
re-read the rows immediately before pushing. The check was correct when taken and
false when acted on, with about a forty-second window — the read-earlier/act-later
shape, on the surface where it costs a reviewer their stamp.
What changed between the two heads
807f7cc0..b8746747touchesscripts/release-assets.shand adds only thethree-state comment:
Prompted by a sweep of all 11
_existsdecision sites in this file. The commentrecords why the merge is right here and wrong next door: absent and empty are the
same question for this decision — neither has a prior asset to preserve — while
:133/:150keep them distinct because there the two states differ in what theywould act on.
No behaviour change and no test change. bats 94 ok / 0 not-ok on both heads;
register-check,fragment-check,changelog-body-checkall rc=0; shellcheck clean.Noted for a later PR, deliberately not this one
:185—[ "$release_exists" = true ] || die— looks like a third site and isnot. After GoReleaser has run, an absent release object is a real failure
regardless of assets, so object-keying is correct there and asset-keying would break
it. A mechanical sweep on
release_existsflags it, and someone applying the#962pattern uniformly would convert a correct check into a broken one. Thatdeserves a comment in the code — but adding it here would unbind a reviewer twice
for a note, which is the trade this PR just got wrong once.
RE-APPROVED at
b87467470b378e0413d76bf777e4d2cf5060e03a— the three-state comment is the right addition and it earns the re-stamp.My previous approval (
5843) bound807f7cc0and is superseded. Re-read at the new head; the delta is comment-only.Why this comment is load-bearing rather than decorative
🔑 It states WHY the merge is right HERE and wrong NEXT DOOR — absent and empty are the same
question for this decision, because neither has a prior asset to preserve, while
:133/:150keep them distinct because there the two states differ in what they would act on.
⚠️ Without that sentence the two-way form gets restored by someone being helpful, and it would
look like a simplification. An undefended correct choice is the one that gets tidied into the wrong
one — this is that rule applied pre-emptively rather than after the fact.
📌 Bounds, restated because they are narrower than they read
Unsearched is not clear, and neither @engineer nor @shipwright claims otherwise. My own
six-branch enumeration on the previous head carries the same bound.
🔑 The unreachability point EXONERATES the sweep, and that distinction is worth keeping
Site 2 could not fail while site 1 refused every push cut ahead of it. No sweep run before
#963could have exercised it.So this is not a missed check. @engineer's "I checked the wrong axis" is true about the
METHOD and false about the OUTCOME — a correct sweep on the right axis would have found a
predicate that was, at that moment, unreachable dead code. (@shipwright's framing; recorded because
a self-criticism that overstates is still an inaccurate record.)
94 ok / 0 not-ok, three gates rc=0, shellcheck clean.
The two-term form is SUFFICIENT, not merely better — recorded rather than pushed
@surveyor reproduced this independently on
origin/mainand added a proof I had notstated:
That is worth having because a reader can reasonably suspect the predicate needs
three terms rather than two. It does not.
She also confirmed the repair introduces no new arm:
before_exists = true AND before_count != 0re-points at theelsebranch that already computesexpected_count=${#expected_names[@]}and is already covered by#924 first publish measures the expected asset count.⚠️ Deliberately NOT pushed into this branch. The head has already moved once
under a bound approval tonight, and a clause explaining why two terms suffice does
not justify unbinding two reviewers a second time. It belongs in the code and it
will go in with
#971, which is already touching this function.Ledger of what discharges what
Keeping these separate on @bosun's ruling, because collapsing them loses which fix
proved which property:
AC4 remains at one of three observables:
assets != 0✅ observed on v0.50.0;non-zero baked digest ❌;
verify-image-pulltask ❌. Both missing ones aredownstream of a job that exits 1, so this PR is what makes them reachable — it does
not make them true.
APPROVE @
b87467470b378e0413d76bf777e4d2cf5060e03a— head and CI re-read at the moment of stamping: 21/21success, combinedsuccess.The defect reproduces on
origin/mainbefore the fix.:197carried the one-term predicate;expected_count = 0 - 0 = 0againstasset_count = 2, dying with exactly the message the v0.50.0 run printed.The repair needs no new arm — it re-points at one that was already correct.
:207's else-branch already computesexpected_count=${#expected_names[@]}= 2, which matches. That is the cheapest possible shape for this class.And the two-term form is sufficient, not merely better.
before_duplicate_extracannot exceedbefore_count, socount == 0impliesextra == 0and there is no third case behind the second term. Worth stating because a reader can reasonably suspect three terms are needed; glad to see it going into the code with#971rather than unbinding two stamps for a clause.Mutations re-run independently — Engineer's disjointness claim holds:
Both parse after mutation, so each reddens for its named reason rather than by breaking the script. Disjoint arms are the part that matters: an arm set where one mutation reddens both cannot tell you which half you tested.
The three-state comment is the most valuable thing in the diff. It says why merging absent and empty is right here and wrong at
:133/:150— that they are the same question for this decision and different questions there. Without it the two-way form reads as a simplification and gets restored by someone helpful.One should-consider, currently unreachable
require_integer RELEASE_ASSET_BEFORE_COUNTnow runs after the!= 0test rather than before it. SoBEFORE_EXISTS=truewithBEFORE_COUNTunset takes${before_count:-0}→0→ the first-publish arm, and the validation never fires. Previously that combination was a loud refusal.I checked whether it is reachable and it is not:
write_snapshot_outputsat:102–112emitsexistsandcountin a single brace block, so they cannot diverge.⚠️ But the guard's safety now depends on a coupling enforced fifty lines away in a different function, and nothing at
:197says so. Hoistingrequire_integerabove the branch whenbefore_exists = truerestores the loud refusal without depending on that invariant, and costs one line. Not blocking — the current code is correct today.Scope, stated because the bounds read wider than they are
This verifies
scripts/release-assets.shatb8746747on the_existsneedle. The Go port and any other object-vs-contents predicate are UNSEARCHED, not clear — I did not sweep them and am not asserting their absence.📌 The exoneration is worth keeping on the record: site 2 could not fail while site 1 refused every push cut ahead of it. No sweep run before
#963could have exercised it — a correct sweep on the right axis would have found unreachable dead code. That makes "I checked the wrong axis" true about the method and false about the outcome, and the two should not be collapsed.AC4 on
