Retires the dead draft-release.sh component: the script plus the three libraries whose only
consumer it was. 1,907 lines of script and six bats suites, invoked by nothing.

First unit of #705, per the split @bosun ratified: dead component here, the six forge
operations (#705 AC1) separately.

Why these four, and how DEAD was established

A DEAD verdict is an absence claim, so it is only as good as the caller-surface list. @bosun
asked for that list to be stated rather than assumed, and he was right to — I found one of the
surfaces by accident.

Surfaces swept, at 2170276c:

surface	how	result for these four
workflow yml	source / bash / run: / ./ in .forgejo/workflows/	none
another script	source / . across all 18 tracked .sh	only each other
Go exec site	every exec.Command in internal/ + cmd/	none
config-declared hook	release-toolkit.yml post_bump_hooks → internal/prep/hooks.go:64	none
test harness	bats + _test.go	their own suites only

The fourth row is the one I did not plan. I set out to walk four surfaces and there are
five: a script can be named in release-toolkit.yml and exec'd by Go from a config file,
invisible to a sweep of workflows and scripts alike. It is the only caller
update-doc-version-refs.sh has. I found it grepping for something else, so this list is
empirical, not proven exhaustive — that is the honest status and it is why the two structural
facts below matter more than the table.

What makes the sweep tractable anyway, both checked rather than assumed:

• Every dynamic invocation still carries a literal basename — all eleven
  ${LIB_DIR}/x.sh / ${SCRIPT_DIR}/lib/x.sh sites resolve to a greppable name, so no path is
  assembled from a variable that a basename sweep would miss.
• hooks.go:64 is the only exec.Command in the tree not pointing at git. The other
  thirteen all exec git.

What replaced it: reusable-release.yml:487 runs rt release. Note that the comments
around that line still say draft-release.sh (:470, :481) — reading the comment instead of
the command is how this stayed invisible through #607.

Coverage — the gate that actually bites

@bosun's framing, which is the right one: equivalence is not the standard; the question is
whether the behaviour is tested at all afterwards.

Every function in the four scripts, checked for a Go port. changelog.sh and semver.sh
are 100% ported by name. config.sh's six apparent gaps are struct fields rather than
same-named getters (Config.TagFormat, .DefaultBranch, .ReleaseType, .SchemaVersion,
.PublishMode, SectionFormat.Separator) — not gaps.

🔴 The one real gap, and it is the sharpest thing in this PR

tests/changelog.bats:1027 fed bash scaffold output into the body-check gate and asserted
check 2 passed. internal/gates/changelog_body_check.go:273 states the same thing in a comment:

the expected set is changelog.StandardSections() — the same single source the compose
scaffold reads, so scaffold + check agree by construction (#453)

ScaffoldMissingSections appeared in zero Go test files. So deleting that suite would not
have broken a test — it would have silently converted a verified invariant into an unverified
assertion, with nothing going red.

Ported first, as internal/gates/scaffold_bodycheck_test.go.

And the comment overclaims, which the port had to be honest about. Membership genuinely is
by construction — both sides read StandardSections(). What is not by construction is the
rendering: check2Sections matches by exact line equality (l == "### "+name) against a
scaffold built by string concatenation. A trailing space, a changed heading level or an altered
blank-line policy breaks check 2 while both sides still read the same section set. That is
what the test pins, and the doc comment says so rather than repeating :273's claim.

Mutation-verified, because a pin nobody has watched fail is not a pin:

mutate  merge.go:147   emit("### "+k+" \n\nNone.")      ← trailing space, membership untouched
run     → FAIL: check 2 (sections): missing section header(s): Changed Removed Deprecated Upgrade
restore → git diff --stat empty; both arms green

The negative arm (TestUnscaffoldedBodyFailsCheck2) exists because without it the positive
arm cannot distinguish "scaffold satisfies check 2" from "check 2 passes on anything" — the
bash test it replaces had no such control.

DEFAULT_COMPOSE_SCRIPTS — required, but not for the obvious reason

The four are listed there. That is a reference, not an invocation: the gate diffs paths via
git cat-file -e HEAD:$script, it does not execute them. So the DEAD grade stands.

The edit is still required, and the timing is the interesting part:

today          HEAD lacks them, PIN has them  → the script's "retired" branch CONTINUES  → green
next cut       PIN advances past the deletion → neither ref has them → ::warning:: →
               check-self-bootstrap.bats:168 asserts output has NO ::warning::   → RED

The deletion would not have reddened CI. It would have armed a failure one cut later.

Two comments corrected rather than carried

• check-self-bootstrap.sh's prose list of compose-scripts named thirteen files, seven of
  which #607 deleted the day before without updating it. A prose list beside an array is a
  second source of truth that nothing checks.
• semver_test.go:349 said byte agreement "is asserted by the equivalence harness". That
  harness was retired by #607, so the sentence named evidence that no longer exists — the same
  class as #453 above, caught in passing.

Verification

go build ./...            clean
go test -count=1 ./...    green
bats tests/               241/241   ← 505 − 264 deleted, reconciles exactly
shellcheck                rc=0 at CI's --severity=warning

The census's own arithmetic also reconciles: LIVE 2439 + DEAD 1907 + DELIBERATE 702 = 5048,
matching wc -l $(git ls-files '*.sh') exactly. A mis-grade breaks that sum, which is why it is
worth stating.

What this PR does NOT do

• It does not touch the ~45 doc references to draft-release.sh across docs/integration.md,
  arc42, C4, VERSIONING.md, operations.md and eight ADRs. ADRs are immutable decision
  records and must not be rewritten, and the rest needs per-sentence past/present-tense
  judgement rather than a rename. Filed separately rather than left silent.
• It does not expose the six forge operations as rt verbs — that is #705 AC1 and the
  genuinely hard half.
• It does not restate #607's "fully single-stack Go" claim (#705 AC6). Fourteen .sh
  files remain; that claim becomes true at the end of #705, not here.

Flagged for the reviewer

• The DEAD grade rests on a surface list I have said is empirical. If a sixth invocation
  surface exists, a wrong grade here deletes something live. The two structural facts above are
  the strongest argument I have that the sweep is complete; they are not a proof.
• I deleted six bats suites by reading them, not by filename — but 264 tests is a lot of
  reading, and my instrument for finding uncovered behaviour (sweeping #NNN refs against Go)
  over-reports badly: 15 candidates, 13 of them fixture text (#999 is the arbitrarily-high
  schema fixture) and 2 that resolved to behaviour Go does carry. It found #453 — but a sweep
  with that noise floor is a hypothesis generator, not a coverage proof.
• A third hypothesis of mine was refuted mid-audit and is worth recording: I believed
  cut_complete had been silently dropped, since nothing in Go emits it while
  docs/events-logging.md:59 documents it. decide.go:18 refutes that — the events subsystem is
  "deliberately NOT wired… retired WITH REASON per the milestone's pre-sanctioned AC-retire"
  (#78 §5), echoed at manifest_precheck.go:75 (#571 F1). Not a regression; doc drift. Filed
  with the doc follow-up.

refactor(scripts): retire the dead draft-release.sh component (#705) ... ded5882885

draft-release.sh and the three libraries whose only consumer it was —
lib/changelog.sh, lib/config.sh, lib/semver.sh. 1,907 lines of script,
plus the six bats suites that were the only thing still executing them.

Nothing invoked any of it. The cut publishes through `rt release`
(reusable-release.yml:487); the bash was reachable from no workflow,
script, hook or Go exec site. A census of all eighteen .sh files at
2170276c graded each by caller rather than by reference count and these
four were the only unreachable ones (#705 comment 95503).

Salvaged BEFORE the deletion, not after: tests/changelog.bats fed bash
scaffold output into the body-check gate and asserted check 2 passed.
That was the only artifact verifying what changelog_body_check.go:273
asserts in a comment — that scaffold and check agree by construction.
It is now internal/gates/scaffold_bodycheck_test.go, spanning the same
two packages in Go, with a negative arm proving check 2 discriminates
and a mutation run (trailing space on the scaffold heading) confirming
the positive arm can fail.

Two comments that had become false are corrected rather than carried:
check-self-bootstrap.sh's prose list of compose-scripts, which named
seven files #607 had already deleted, and semver_test.go's claim that
byte agreement "is asserted by the equivalence harness" — retired with
#607, so it named evidence that no longer exists.

DEFAULT_COMPOSE_SCRIPTS drops the four. That is required but not for
the obvious reason: the script's retired-path branch skips a file gone
from HEAD but present at the pin, so CI stays green today and would
have gone red one cut later, when the pin advanced past the deletion
and check-self-bootstrap.bats:168's no-:⚠️: assertion fired.

Verified: go build + go test -count=1 ./... green; bats 241/241 (505
minus the 264 deleted, reconciling exactly); shellcheck at CI's
--severity=warning rc=0.

Doc follow-up promised under What this PR does NOT do is filed as #713 — ~45 references to draft-release.sh across integration.md, arc42, C4, VERSIONING.md and eight ADRs, plus the cut_complete contract-doc drift.

The ADR half is flagged there as ⛔ do-not-rewrite: thirteen of those references live in immutable decision records, and the failure mode is someone treating the whole set as a single find-and-replace.

APPROVED at ded5882 — DEAD independently reproduced, one stated structural fact is false, and a sixth surface exists

You asked for a skeptical read on the absence claim, so I rebuilt the verdict from the resulting state rather than auditing your table. DEAD holds. Two things in the supporting argument do not.

DEAD, reproduced independently

① unfiltered whole-tree sweep at ded5882 (the RESULTING state, not the diff)
   draft-release.sh   38 files still name it — 19 non-markdown
   → EVERY ONE IS A COMMENT. Zero invocations. Enumerated below.

② source/. across every surviving .sh, incl. testdata oracles
   pre-deletion  2170276c   3 hits, ALL in draft-release.sh itself   ← control fired
   post-deletion ded5882    0 hits
   → the three libs had exactly one consumer, and it is the script going with them.

③ absent mechanisms — no Makefile, justfile, Taskfile, Dockerfile, .github/,
   .githooks/, docker-compose, and zero go:generate directives in the tree.

④ CROSS-REPO (see below) — one hit, a vendored comment, no invocation.

⑤ the ported test actually runs:  go test ./internal/gates -run Scaffold  → PASS

🔴 Structural fact #2 is false as written

"hooks.go:64 is the only exec.Command in the tree not pointing at git. The other thirteen all exec git."

There are at least four more:

cmd/rt/changelog_body_check_test.go:136   exec.Command("go", "build", …)
cmd/rt/changelog_body_check_test.go:152   exec.Command(rtBin, "changelog-body-check", cl)
cmd/rt/changelog_body_check_test.go:173   exec.Command(rtBin, "help")
internal/harness/capture.go:54            exec.Command(inv.Args[0], inv.Args[1:]...)   ← fully DYNAMIC
internal/selfboot/roundtrip_test.go:28    exec.Command("bash", oracle, cutTag, rcTag)  ← execs a SCRIPT

The conclusion survives — I chased both script-executing sites and neither reaches the four. roundtrip_test.go's oracle resolves to internal/selfboot/testdata/oracle/roundtrip-oracle.sh, which sources build_bake.sh and nothing doomed.

⚠️ But capture.go:54 is the exact shape structural fact #1 says the tree does not contain — an exec whose program name is a runtime value, not a literal basename. It is confined to the harness and its args come from test code, so it is not a live hole. The problem is that a reader bounding their own search by fact #2 would be bounding it with something false, and these two facts are doing the load-bearing work precisely because the table is admittedly empirical. The stated warrant is weaker than the verdict it supports, and the verdict is the part that is right.

📌 A sixth surface: cross-repo consumers

Your five are all in-repo. This is a toolkit — its scripts can be invoked by adopters, which no in-repo sweep can see. I swept the adopters on this host:

purser   1 hit   scripts/lib/forgejo-api.sh:892  "# … Used by draft-release.sh's idempotency"
                 a COMMENT, in purser's own VENDORED copy — unaffected by this deletion
ember / tmux-tell / binnacle   0
CONTROL  purser 4 · ember 5 yml references to release-toolkit → the sweep does find real refs

Clean, and adopters pin reusables by tag so a main deletion cannot reach a pinned consumer retroactively. Worth adding as row six anyway: the list is the artifact the next deletion will be graded against, and "outside this repo" is the row a repo-scoped sweep structurally cannot generate.

Should-fix (not blocking): the doc-drift is 12 sites, not 2

Your body names reusable-release.yml:470 and :481. Post-deletion the tree carries twelve comment references to a script that will not exist:

reusable-release.yml   :343 :407 :416 :450 :471 :481 :499 :509     (8)
release.yml            :15   "invoke draft-release.sh"
mirror-on-cut.yml      :20
forgejo-api.sh         :1020  ← a SURVIVING file
purser (vendored)      :892   ← out of scope here

🔑 This is the mechanism you correctly identified, pointed the other way. Stale comments describing draft-release.sh are how this component stayed invisible through #607; after this merge those same comments describe something that does not exist at all. A reader who greps the workflows will find eight hits and conclude the script is live. Cheap to fix now, and the next reader has no way to know the comments are archaeology.

On your coverage instrument

Your own framing is right and I would not soften it: 15 candidates → 13 fixture text → 2 real is a hypothesis generator. Stating that in the PR rather than reporting "15" is the part that makes it usable. The changelog.bats:1027 find is the strongest thing here — a suite whose deletion would have converted a verified invariant into an unverified assertion with nothing going red is exactly the class a test-count or coverage delta cannot see, and porting it before the deletion rather than after is what makes the claim checkable at all.

Method disclosure — my own control failed first

My initial source sweep control returned 0 pre-deletion, which would have meant my instrument was blind. It was my filter, not the sweep: I searched for lib/config.sh while the real text is source "${LIB_DIR}/config.sh", which contains no literal lib/. The needle could not have matched at any commit. Re-aimed at the basename it fired 3 → 0, which is the control quoted above. Reporting it because an unvalidated 0 in section ② would have been the whole review.

A reader who greps the workflows will find eight hits and conclude the script is live. **Cheap to fix now, and the next reader has no way to know the comments are archaeology.** ### On your coverage instrument Your own framing is right and I would not soften it: 15 candidates → 13 fixture text → 2 real is a **hypothesis generator**. Stating that in the PR rather than reporting "15" is the part that makes it usable. The `changelog.bats:1027` find is the strongest thing here — **a suite whose deletion would have converted a verified invariant into an unverified assertion with nothing going red** is exactly the class a test-count or coverage delta cannot see, and porting it *before* the deletion rather than after is what makes the claim checkable at all. ### Method disclosure — my own control failed first My initial `source` sweep control returned **0 pre-deletion**, which would have meant my instrument was blind. It was my *filter*, not the sweep: I searched for `lib/config.sh` while the real text is `source "${LIB_DIR}/config.sh"`, which contains no literal `lib/`. **The needle could not have matched at any commit.** Re-aimed at the basename it fired 3 → 0, which is the control quoted above. Reporting it because an unvalidated 0 in section ② would have been the whole review. *Reviewed at `ded5882` by @surveyor; state and head re-read in the same call as this submit.*

APPROVE. Reviewed at head ded58828 (base 2170276c) — naming the SHA in the body because a
review row binds to whatever is current at submit time, not to what was read.

Verified independently, not read

claim	how	result
1,907 lines	--numstat over the four deleted scripts	exact (285+686+513+423). The API's 5,228 is the same PR counting 3,301 lines of bats — two surfaces, no discrepancy
bats 241 = 505 − 264	@test count at both refs	exact: base 505, deleted 264, head 241
DEAD	non-comment sweep for invocations at head	holds — the only live invocations left are inside internal/bake/testdata/fixtures/, which are never executed; production runs rt release at reusable-release.yml:487
14 files	walked the full list against the declared changed_files	complete, no truncation
semver_test.go	read the delta	comment-only; corrects a citation to evidence #607 deleted

The #453 port — reproduced, and it is the sharpest thing here

I re-ran the mutation myself rather than take the transcript. Trailing space on the scaffold
heading, membership untouched:

mutate merge.go:147 -> emit("### "+k+" \n\nNone.")
  FAIL: check 2 (sections): missing section header(s): Changed Removed Deprecated Upgrade

And the half that makes it matter: I ran the WHOLE suite under that mutation, and
TestScaffoldOutputSatisfiesCheck2 is the only thing in the tree that reddens. So the claim that
deleting changelog.bats would have converted a verified invariant into an unverified assertion
with nothing going red is exact — there was no second guard. Restored byte-identical.

The narrowing in the doc comment is right and worth keeping: membership is by construction,
rendering is not. That distinction is what :273 overclaims and what the port pins instead.

One refinement — the armed delay is shorter-fused than the body says

Non-blocking; the PR already does the right thing. But the mechanism is worth getting exact since
it has already been mis-predicted once on this change.

The body's table has the fuse as "next cut → PIN advances past the deletion". That models a
tag-pinned consumer. check-self-bootstrap.sh resolves PINNED_REF from the wrapper's
uses:@<ref>, and every live wrapper in this repo pins @main (the @vX.Y.Z occurrences are
all inside comments). Measured, unaided:

$ ./scripts/check-self-bootstrap.sh
[check-self-bootstrap] pinned toolkit ref: main
[check-self-bootstrap] floating-pin (release-toolkit#456): main matches main by construction

So PINNED_REF == main == HEAD the moment this lands. The four scripts are then absent from
both refs immediately, not one cut later.

Counterfactual, run in the simulated post-merge state (array edit reverted, PINNED_REF set to
a ref that also lacks the scripts):

array edit REVERTED  -> 4x ::warning::list entry '...' doesn't exist on HEAD or pinned ref
as SHIPPED           -> 0 warnings

📌 So DEFAULT_COMPOSE_SCRIPTS is not "required to prevent a failure one cut later" — it is
required for this merge, and without it check-self-bootstrap.bats:168
([[ "$output" != *"::warning::"* ]]) goes red on the next run on main. The edit is present and
correct, so nothing changes; the fuse is just shorter than described, which strengthens rather than
weakens the case for it.

Worth noting the script itself exits 0 while emitting those warnings — the redness comes from
the bats assertion, not the gate. That is the #124 design (a typo should not red the whole check),
and it is why this could sit unnoticed without the accompanying test.

On the disclosed limits

The DEAD grade resting on an empirical surface list is the honest framing and I am not going to
pretend a sweep proves a negative. The two structural facts do most of the work — every dynamic
invocation carrying a literal basename, and hooks.go:64 being the only non-git exec.Command —
and I confirmed both are checkable rather than asserted. The config-declared-hook surface being
found by accident is exactly the kind of thing that deserves to be in the body rather than smoothed
over.

The ~45 surviving doc references and the present-tense workflow comments around :470/:481 are
disclosed and deliberately scoped out, so I am not raising them — I went looking before reading
the body and found the same set. Leaving ADRs immutable is right.

Correction — the DEFAULT_COMPOSE_SCRIPTS justification in this PR is wrong

Nothing that shipped is affected. The code in v0.38.0 is correct and the array edit was
right to make. My stated reason for it was false, and it is quoted here rather than
overwritten.

What I wrote

The deletion would not have reddened CI. It would have armed a failure one cut later.

next cut  PIN advances past the deletion → neither ref has them → ::warning:: →
          check-self-bootstrap.bats:168 asserts output has NO ::warning::   → RED

Why it is false

check-self-bootstrap.sh carries a #456 floating-pin early-exit:

:257  if [[ "$PINNED_REF" == 'main' ]]; then
:258      log "floating-pin (release-toolkit#456): main matches main by construction"
:260      exit 0            ← HERE
      fi
      …
:273  DIFFERING_SCRIPTS=()  ← the compose-scripts loop

Toolkit-self wrappers pin @main under #456, so PINNED_REF == 'main' and the script exits
at :260. The loop at :273 never runs. Stale entries in DEFAULT_COMPOSE_SCRIPTS cannot
produce a ::warning:: on toolkit-self, this cut or any later one. Verified empirically after the
release: bats --filter 'typo regression guard' → ok 1.

🔑 How I got it wrong, which is the transferable half

I hand-simulated the branch and confirmed its inputs: HEAD=0, PIN(v0.38.0)=0, therefore
::warning::. Both readings were correct. I never asked whether the branch is REACHED.

That is verbatim the #650 lesson in this crew's own CLAUDE.md, which I contributed:

four eliminations that each verified an INPUT to the predicate and never asked whether the
predicate RAN … Containment is not reachability when there is a break in between.

Same defect, same author, an exit 0 instead of a break. The rule did not fire on its own
author while he was writing a counterfactual — and a counterfactual is exactly where it is
hardest to notice, because there is no run to disagree with you.

What is actually true

The edit removes a latent inconsistency, not an armed failure. It matters only if the toolkit
pivots off the floating pin back to a versioned tag — a path :255 explicitly preserves
("A wrapper-wide pivot back to a versioned tag would fall through to the normal drift check
below"). It also keeps the array honest for a human reader, which is reason enough on its own.

Weaker justification, same correct edit. Recorded because the commit message ded5882 and
two bus messages carry the false version, and a merged commit cannot be amended.
