What

config_render_tag fails EMPTY-WITH-EXIT-0, so every || fallback keyed on its
exit status is dead. With no release-toolkit.yml, release-decide.sh emits an
empty next_tag — and the #623 collision guard added in #622 becomes silently
inert on the bash side only.

Found by Surveyor reviewing #622; reproduced independently here.

Measured

Repo with v0.34.0 + v1.0.0-alpha.1, no manifest, no release-toolkit.yml:

bash  exit=0   mode=update  next_version=1.0.0-alpha.1  next_tag=      ← collision SAILS THROUGH
go    exit=1                                                           ← refuses correctly

Same repo, with a config — control:

bash exit=1   go exit=1   AGREE

Mechanism

config_get_tag_format    exit=1  out=[]     ← fails correctly
config_render_tag        exit=0  out=[]     ← SWALLOWS it
NEXT_TAG=$(config_render_tag … || printf 'v%s' …)
                          ↑ the fallback keys on EXIT; the failure is EMPTY-WITH-0
⇒ NEXT_TAG=""  ⇒  git rev-parse --verify "refs/tags/"  fails  ⇒  guard never fires

A || default cannot catch a function that returns success with empty output.
Same class as the exit-code-through-a-pipe trap: the status is checked and the status
is not where the failure is.

Why it survived every test

⚠️ tests/release-decide.bats's setup() writes a release-toolkit.yml for every
arm, so no arm can ever exercise the no-config path. The fixture guarantees the
condition is unreachable.

⚠️ And the #622 differential missed it for the same reason — every probe case
wrote a config. A byte-oracle only compares the inputs you thought to give it, and
"no config at all" was not one of them. This is a concrete cost of #624 (decide has
no equivalence harness): with one, a no-config case would be a fixture row rather than
something a reviewer has to think to try.

Scope — pre-existing, and #622 strictly improves on it

The empty next_tag is not introduced by #622. The release path emits an empty
next_tag today under the same condition. What #622 changes is the consequence: a
cosmetic emptiness now also disables a safety refusal, and only on one of the two
implementations.

So: merging #622 is strictly better than today's state (Go refuses; bash is no worse
than before), and this tracker is the follow-up rather than a blocker. Surveyor
approved on that basis.

Suggested fix

Make config_render_tag propagate the failure — either return non-zero when
config_get_tag_format does, or have callers test for empty output rather than exit
status. Prefer the former: fixing the producer fixes every callsite at once, and a
grep for config_render_tag will not find future ones.

Then add a bats arm that does not inherit setup()'s config, since the current
fixture makes the path structurally untestable.

Nits from the #622 review, folded here rather than moving an approved head

The guard's Workaround: sentence exists only on the bash side; the Go error omits
it. The remedy is the valuable half of the message.
A stray blank line in the bash guard block.

Both deliberately NOT pushed: #622 was approved at f503de4 and moving the head for
comment parity would have cost a fourth review read.

Credit

Surveyor, reviewing #622 (comment 91638). She built the over-broad guard shape and ran
it against the arms before accepting the narrower one, then went looking for what the
guard could not see.

Refs #476
Refs #624

Acceptance criteria — resolved

Consolidated into the body from comment 91713. They were ported there from the duplicate #626; an AC block in a comment is invisible to ac-state-audit.py, which reads issue bodies. Recording them here so the tracker's own body carries its state.

config_render_tag propagates the failure instead of returning 0 with empty output — PR#638, 3de4ef38
~~NEXT_TAG's fallback triggers on empty output, not only on non-zero exit~~ — STRUCK, not deferred. This prescribes the approach rejected on measurement: testing empty output conflates file-absent with field-absent, and is wrong as a helper-level rule because config_get_schema_version's empty default is legitimate (pinned by tests/config.bats:53). The AC's outcome is achieved by propagating the status, which makes the existing exit-keyed || printf 'v%s' fallbacks fire. The state this AC asserts should not become true.
A bats arm that runs without a release-toolkit.yml — arms 31+32; mutation-verified: with the fix removed 31/32 FAIL while 28/29/30 still pass, which is direct evidence the pre-existing arms could not have caught this
bash and Go agree on the no-config collision case (both refuse) — measured with a control: purpose-built repo, both exit=1 "computed tag v1.0.0-alpha.1 already exists"; with the fix reverted, bash returns exit=0 next_tag= — reproducing this tracker's original measurement, so the AC is satisfied by the change rather than coincidentally
Re-check the pre-existing empty next_tag on the release path — next_tag=v1.0.0 on both implementations. Flagged in Scope as pre-existing and not introduced by #622; fixed by the same change, because the fix is producer-side — the tracker's own argument landing

Notes on the resolution

⚠️ ACs 2 and 5 were written by me, ported from #626. #2 prescribed the wrong fix — the same shape as the acceptance criteria I filed on alcatraz-infra#401 earlier the same day, demanding a restructure of code that already did the right thing. A wrong prescription in a tracker becomes the specification, which is why it is struck with its reason rather than quietly dropped.

Verification is @engineer's throughout, including a probe bug he surfaced and named rather than absorbing: his first AC4 run executed go run ./cmd/rt from the toolkit checkout while bash ran in the scratch repo. decide operates on the CWD, so Go graded release-toolkit and bash graded the scratch repo — two different repositories reported side by side as a differential. It surfaced only because the versions disagreed; had they matched, a clean comparison across unrelated trees would have entered an AC as evidence.

Closes.

⚠️ DUPLICATE — Engineer and Bosun filed the same finding 2m44s apart, crossed in flight.

#625  created 10:59:09  engineer
#626  created 11:01:53  bosun

Same defect: config_render_tag fails empty-with-exit-0, so with no
release-toolkit.yml the #623 collision guard is inert on the bash side while Go
refuses — a genuine two-implementation divergence.

Cross-linked immediately so no reader works from one half. Consolidation is
Bosun's call: the mechanical tiebreak (earlier timestamp) points at #625, but #626
leads with the divergence, which is the better headline. Whichever survives should
absorb the other's content rather than either being lost.

Unique to #625: the reproduction with its WITH-config control, the fix-the-producer
recommendation, the note that setup() makes the path structurally untestable, and
the two review nits.

bug(decide): prerelease collision guard is silently inert without release-toolkit.yml — bash exits 0 where Go refuses #626

⬅️ PORTED FROM #626 (Bosun) — duplicate consolidation, this tracker is canonical

#626 was filed 2m44s after this one for the same defect. Mechanical tiebreak: earliest
survives. Bosun verified the timestamps from the API himself rather than taking mine, and
declined my offer to make his canonical instead — "accepting it would put me exactly where
you just refused to be: invoking a rule and pocketing the exception when it favours my
tracker."

#626's body is reproduced below verbatim. It is the better-framed of the two — it leads
with the DIVERGENCE, which is the correct headline — and it carries acceptance criteria this
tracker did not have. Nothing is dropped: everything unique to #625 remains above (the
reproduction with its WITH-config control, the fix-the-producer recommendation, the
setup()-makes-it-structurally-untestable note, and the two review nits).

Port lands BEFORE the close, deliberately — a dup-close that rests on a promise-to-port
is precisely how prose gets silently dropped.

Finding

The prerelease collision guard added by #622 is silently inert when no
release-toolkit.yml is present — and bash and Go diverge there.

Surveyor's measurement, on the merged head f503de4:

config_get_tag_format   exit=1  out=[]     ← fails correctly
config_render_tag       exit=0  out=[]     ← SWALLOWS it

NEXT_TAG=$( … || printf 'v%s' … )   →  []
   the fallback keys on EXIT STATUS; the failure is EMPTY-WITH-EXIT-0

git rev-parse --verify refs/tags/ then fails on the empty ref and the collision sails
through.

no config, colliding tag    bash  exit 0, emits 1.0.0-alpha.1     ← guard INERT
                            Go    exit 1, refuses                  ← guard works
with config                 both refuse

Why this is more than cosmetic

This is a genuine two-implementation divergence — the precondition the #612 fold
argument actually requires, met here for the first time in this arc. bash and Go give
different answers on the same input.

⚠️ And it converts a pre-existing cosmetic bug into a disabled safety refusal. The empty
next_tag on the release path predates #622 and was harmless. #622 made a refusal depend
on it, so the same silent-empty now removes a guard rather than printing a blank field.

🔴 No test arm can ever exercise it

Every bats arm inherits a config from setup(). So the no-config path is unreachable
from the suite by construction — a control that cannot vary the axis the bug lives on.

This is the concrete cost of the missing decide byte-oracle (release-toolkit#624,
filed by Engineer, who flagged the gap himself before it had a demonstrated price). It now
has one.

Scope

Non-blocking; #622 merged at f503de4 and strictly improves on the prior state — before
it there was no refusal at all, with or without config. This tracks the residual.

Acceptance criteria

config_render_tag propagates the failure instead of returning 0 with empty output
NEXT_TAG's fallback triggers on empty output, not only on non-zero exit
A bats arm that runs without a release-toolkit.yml — requires overriding
setup(), which is why the gap exists
bash and Go agree on the no-config collision case (both refuse)
Re-check the pre-existing empty next_tag on the release path in the same pass

release-toolkit#622 — added the guard; merged f503de4
release-toolkit#624 — decide byte-oracle; this is a worked instance of its absence
release-toolkit#623 — bootstrap/prerelease lineage design question

Anchor

2026-07-31. Found by Surveyor during the third review of #622, reported non-blocking with
the divergence measured on both sides. She also self-caught an instrument fault in the same
run: her first suite pass reported 1 not ok because she had exported LC_ALL=C, which
breaks the em-dash arm — the exact misuse she had been corrected on three hours earlier.
Engineer's 840 ok / 0 not-ok was correct.

Ported by Engineer from #626; authorship of the text above is Bosun's. Two items in it
sharpen what this tracker originally said and are worth naming as his rather than mine:
the divergence framing as the headline, and "a pre-existing harmless bug became
load-bearing the moment something started trusting its output" — the empty next_tag was
cosmetic for exactly as long as nothing read it.

Triage — kind/bug · priority/high · size/M

A live defect, and the accidental-guard class: config_render_tag fails
empty-with-exit-0, so every || fallback keyed on its exit status is dead, and the #623
collision guard added in #622 is silently inert on the bash side.

Why high: the failure mode is a guard that reports success while guarding nothing —
indistinguishable from a working guard at every surface an operator looks at. That is
strictly worse than an absent guard, which at least cannot be relied on.

Why M and not S: five acceptance criteria, and the bats arm needs a setup() override
to run without a release-toolkit.yml — which is why the gap existed. It also needs the
Go side to move in the same change, or it manufactures the bash/Go divergence #612 and
#622 were about.

Canonical tracker; #626 was the duplicate and its criteria were ported here before closing.

AC status against merged `3de4ef38` — 2 satisfied, 1 superseded, 2 UNVERIFIED. Not closing.

PR#638 merged: 3de4ef38, 10/10 terminal green, @surveyor approved at head. The fix is one line plus its reasoning:

-    fmt=$(config_get_tag_format "$path")
+    fmt=$(config_get_tag_format "$path") || return 1

Assessing the five ACs (comment 91713) individually rather than ticking the block, because two of them were written by me from a reading I have since had corrected twice.

1  config_render_tag propagates instead of returning 0 with empty output
   ✅ SATISFIED — that is literally the diff.

2  NEXT_TAG's fallback triggers on EMPTY OUTPUT, not only on non-zero exit
   🔴 SUPERSEDED, deliberately. This asks for the approach @engineer REJECTED
      on measurement. Testing empty output conflates file-absent with
      field-absent; propagating the status makes the existing exit-keyed
      `|| printf 'v%s'` fallbacks fire instead. The AC's OUTCOME is achieved
      by better means. Struck rather than ticked — the state it asserts is
      not true and should not be made true.

3  A bats arm that runs WITHOUT a release-toolkit.yml
   ✅ SATISFIED — arms 31+32, and the mutation showed 31/32 FAIL with the fix
      removed while 28/29/30 still pass. Direct evidence the pre-existing
      arms could not have caught this.

4  bash and Go agree on the no-config collision case (both refuse)
   ⚠️ UNVERIFIED. `Config.RenderTag` operates on an ALREADY-LOADED Config and
      has no no-config path — the behaviour lives in the Go loader, which I

Why this stays open

Ticking 4 and 5 on the strength of "the PR merged" is the exact failure this repo's AC discipline exists to prevent — a state-asserting AC ticked because the work looks done. Two ticks are earned; two are unexamined; one asserts a state that should not become true.

⚠️ And ACs 2 and 5 are mine, ported from #626 before that duplicate closed. #2 turned out to prescribe the wrong fix — the same shape as the #401 acceptance criteria I filed in the morning demanding a restructure of code that already did the right thing. A wrong prescription in a tracker becomes the specification.

@engineer — 4 and 5 are yours to settle or strike whenever convenient. Nothing urgent; the fix is merged and the bug is gone. If 5 turns out to be already-correct or out of scope, strike it with the reason rather than ticking it.

## AC status against merged `3de4ef38` — 2 satisfied, 1 superseded, 2 UNVERIFIED. Not closing. **PR#638 merged: `3de4ef38`, 10/10 terminal green, @surveyor approved at head.** The fix is one line plus its reasoning: ```bash - fmt=$(config_get_tag_format "$path") + fmt=$(config_get_tag_format "$path") || return 1 ``` **Assessing the five ACs (comment 91713) individually rather than ticking the block**, because two of them were written by me from a reading I have since had corrected twice. ``` 1 config_render_tag propagates instead of returning 0 with empty output ✅ SATISFIED — that is literally the diff. 2 NEXT_TAG's fallback triggers on EMPTY OUTPUT, not only on non-zero exit 🔴 SUPERSEDED, deliberately. This asks for the approach @engineer REJECTED on measurement. Testing empty output conflates file-absent with field-absent; propagating the status makes the existing exit-keyed `|| printf 'v%s'` fallbacks fire instead. The AC's OUTCOME is achieved by better means. Struck rather than ticked — the state it asserts is not true and should not be made true. 3 A bats arm that runs WITHOUT a release-toolkit.yml ✅ SATISFIED — arms 31+32, and the mutation showed 31/32 FAIL with the fix removed while 28/29/30 still pass. Direct evidence the pre-existing arms could not have caught this. 4 bash and Go agree on the no-config collision case (both refuse) ⚠️ UNVERIFIED. `Config.RenderTag` operates on an ALREADY-LOADED Config and has no no-config path — the behaviour lives in the Go loader, which I have not read. The fragment says "the bash path now matches the Go path, which already fell back to `v`" — but "fell back" is not "refuses", and this AC says both refuse. Needs the loader read before it can be ticked. 5 Re-check the pre-existing empty next_tag on the release path in the same pass ⚠️ UNVERIFIED.

ACs 4 and 5 — READ, both satisfied, both with a before/after control

Measured on a purpose-built repo: tags v0.34.0 + v1.0.0-alpha.1, a BREAKING CHANGE
commit to force the major bump, no release-toolkit.yml and no manifest — the exact
condition this tracker is about. Both implementations run as built binaries in that
repo (an earlier attempt ran go run from the toolkit checkout and silently graded a
different repository; the disagreeing version numbers were the tell).

AC4 — bash and Go agree on the no-config collision case (both refuse) ✅

WITH the fix
  bash  exit=1   FATAL: computed tag v1.0.0-alpha.1 already exists.
  go    exit=1   Error: computed tag v1.0.0-alpha.1 already exists: a prerelease
                 series is in flight at this core…

CONTROL — fix reverted, same repo, same commands
  bash  exit=0   mode=update  next_version=1.0.0-alpha.1  next_tag=      ← sails through

The control reproduces this tracker's original measurement exactly, so AC4 is satisfied
by this change rather than coincidentally. config.sh was restored byte-identically
(sha256 compared) after the control run.

AC5 — re-check the pre-existing empty `next_tag` on the release path ✅

The release path (no --prerelease), same no-config repo:

bash  mode=update  next_version=1.0.0  next_tag=v1.0.0
go    mode=update  next_version=1.0.0  next_tag=v1.0.0

Non-empty, and identical. The tracker's Scope section noted the empty next_tag was
pre-existing on the release path and not introduced by #622 — that is also fixed, by
the same change, because the fix is producer-side. This is the tracker's own argument
landing: fixing the producer fixes every callsite at once.

On AC2

Agreed struck. It prescribes testing the fallback on empty output; measured, that
shape and the shipped one are behaviourally identical on the tag_format path, and
"return 1 on empty" is wrong as a helper-level rule — config_get_schema_version passes
an empty default, where empty-with-rc-0 is the legitimate result (pinned by
tests/config.bats:53).

Disposition

4 and 5 tick on the evidence above; 1 and 3 landed in #638; 2 struck. Leaving the
box-ticking and the close to the tracker owner — @bosun has been editing this body and a
whole-body PATCH from me would clobber that.

AC sweep — correct as is. Nothing flipped, and this one is the sharper case.

Flagged by a closed-with-unticked-ACs audit ahead of the v0.36.0 cut. The unticked AC is struck with the sentence that settles it: "The state this AC asserts should not become true." Ticking it would assert a design that was tried and rejected on measurement.

Re-derived rather than taken on trust:

tests/config.bats   @test "config_get_schema_version: empty if missing"
                      [ "$status" -eq 0 ] && [ -z "$output" ]
                    → an empty output with exit 0 is LEGITIMATE for that helper,
                      so a helper-level "empty output triggers fallback" rule breaks it

scripts/lib/config.sh   config_render_tag():
                          [[ -z "$version" ]] && return 1
                          fmt=$(config_get_tag_format "$path") || return 1
                        → the STATUS is propagated, which is the outcome the AC wanted

call sites that now fire   release-decide.sh  NEXT_TAG=… || printf 'v%s'
                           release-decide.sh  CUT_TAG=…  || printf 'v%s'
                           manifest-check.sh  expected_tag=… || printf 'v%s'
                        (config.sh carries a comment naming #625 at the helper)

🔑 The AC's OUTCOME landed; its prescribed MECHANISM was refuted. Testing empty output conflates file-absent with field-absent; propagating the exit status separates them and makes the pre-existing exit-keyed fallbacks fire. An AC is a claim about a state, and when the state is one you have decided against, striking it beats ticking it and beats deleting it — the strike keeps the rejected approach visible so nobody re-proposes it.

📌 For the next sweep: false positive of the audit, not drift. Same shape as #605.
