Refs #606 — the dogfood AC (AC7) and the adopter-doc AC (AC6). Does not close the tracker; two items remain and one of its ACs turns out to be already satisfied. See the bottom.

🔴 Lead finding: the docs described the thing this action REPLACED

Ahead of the migration itself, because it is the half most likely to mislead a reader today.

docs/integration.md's docker-action section claimed:

"Caching is automatic (#606). The binary is cached per version… the checksum verify runs on cache hits too, against a freshly-fetched checksums.txt."

That action fetches nothing. It is a docker action pinned to an image digest, whose entrypoint copies /rt out of the image (#794). There is no fetch, no checksums.txt, and no per-version binary cache anywhere on its path.

🔑 The text described the composite the action replaced — sitting inside the section that documents the replacement. The replacement was written; the description of the replaced thing stayed; nothing goes red. Same shape as the false deferral comment below, on a docs surface instead of a workflow one.

Replaced with the digest-pin integrity story — integrity comes from the pin rather than from a verify step an adopter could skip — and deliberately with no speed numbers: the old "~10s fetch, sub-second restore" figures belonged to fetch-rt.sh and none has been measured for an image pull.

🔴 The deferral rested on a false premise, both clauses

reusable-release.yml carried its own copy of the bootstrap, deferred by:

"NOT a migration to the composite action (which is fetch-only and would drop the ADR-0008 §4a @main build-exception)"

scripts/bootstrap-rt.sh   main) arm — BUILDS from source, cites "ADR-0008 §4a" BY NAME
composite/action.yml      bash "$script"   ← the composite is what invokes it

And the divergence bought nothing: the inline cache block was identical to the composite's own first step once normalised for the ref expression — same action, version, path, key, and startsWith(…, 'v') guard.

⚠️ That identity claim was ungraded when I first made it. My control mutated rt-REF-linux-amd64, which never matches rt-${{ REF }}-linux-amd64 — a needle that cannot match returns the answer you expected. Re-run with occurrences asserted (2 applied): a mutated line does diff.

A comment describing a sibling file's behaviour, wrong about it, load-bearing for a deferral. Nothing goes red when that rots.

🔑 One deliberate behaviour change — toolkit's own path only

	inline (before)	bootstrap-rt.sh (after)
BUILD source	always .release-toolkit — the toolkit at the resolved ref	prefers $GITHUB_WORKSPACE when it carries cmd/rt + go.mod

So a toolkit-self cut now compiles the commit under test. The two coincide on an ordinary push-to-main cut and diverge only if main moved between the checkout at :144 (caller repo) and :203 (toolkit @ resolved ref).

The replaced comment's own stated intent — "dogfood its current rt when cutting" — is the workspace commit, not whatever a second checkout resolved to. So this closes a gap between that comment and its implementation rather than opening one. Already pinned by existing arm 44 (#728/#861).

Adopters are unaffected: their workspace has no cmd/rt, so the script falls back to .release-toolkit exactly as the inline arm did.

✅ One regression the swap would have caused, fixed rather than accepted

The inline Go preflight named the adopter remedy; the script's said only "requires Go on the runner". The script now carries the fuller message — improving all six callsites rather than only this one.

Verification

New bats arm keys on the build artifact, not a step name — a renamed step would slip past a name check while still compiling its own rt.

Markdown tables parsed and counted rather than eyeballed (12 tables, all contiguous); the parser was controlled by injecting a blank line, which it detects.

Docs

Adds "Which bootstrap applies to you" — there are two mechanisms and adopters touch one. The composite is not an adopter shape and the path is the tell: ./.release-toolkit/composite/bootstrap-rt is relative to a checkout of the toolkit, and its inputs are the four #794 deliberately removed from the adopter-facing action.

The stale-paragraph retraction is the lead finding — see the top of this body.

🔴 AC5 is already satisfied — it was never blocked on #941

The tracker records the sub-second measurement as "BLOCKED… that job has never completed, so the arm has produced no number since it was written. Clears with #941." Both halves are false, measured from the runner's own logs:

task 22783   2026-08-19   verify-fetch-arm  status=success   cache-HIT end-to-end: 53ms
task 23601   2026-08-20   verify-fetch-arm  status=success   cache-HIT end-to-end: 54ms
task 24206   2026-08-20   verify-fetch-arm  status=success   cache-HIT end-to-end: 51ms

Three successful runs, ~52ms against an AC asking under 1000ms — a week before the tracker was restated. This is the #648 arm that ran green three times and then regressed; the successes are real and predate the regression #941/#950 fixed.

⚠️ Stated in the past tense deliberately: these are durable run records about 2026-08-19/20, not a claim about today. A fresh number should come from the next cut, which will also be the first exercising this migration.

What this PR does NOT do

• It does not finish the tracker. frankenbit/release-toolkit#606 stays open. (Written with the qualified form deliberately: ac-closure-check matches a close keyword POSITIONALLY, so the negated sentence that stood here — "it does not finishes frankenbit/release-toolkit#606" without the space — WOULD have closed it on merge. The gate caught it.) Open question 1 (is the release path's restore-only cache the wanted shape?) is untouched — the migration makes it moot for this callsite, since the composite now owns the cache step, but the general question of restore-only-vs-save is not ratified anywhere.
• It does not re-measure the cache-hit path. The existing numbers are quoted with their dates; no new run has happened yet.
• It does not touch the five PR-CI reusables — they were already on the composite.
• It does not change what #794's docker action does, only what the docs say about it.

Uncertainty

The behaviour change is the part I would most like a second reader on. I believe compiling the commit under test is both the intended semantics and the safer one, but it is a change to the release path, and the release path has been wedged twice today. If a reviewer would rather have the migration without it, the composite would need an input pinning the build source — say so and I will add it here rather than after merge.

APPROVED at ddfe0df4d0f6a0230ccca063c5beb5f145f1f1c4 — the behaviour change is safe, and STRICTER than you described it

You asked for a second reader on the one deliberate behaviour change. That is what I checked first.

✅ The adopter-safety claim holds by construction, on two conditions rather than one

bootstrap-rt.sh:54   if [[ -d "$workspace/cmd/rt" && -f "$workspace/go.mod" ]]; then

You described the guard as "no cmd/rt in their workspace". It requires BOTH cmd/rt AND go.mod — so an adopter who happens to vendor a cmd/rt directory still falls through to the resolved ref. The claim is safer than the sentence defending it, which is the right direction for that gap to run.

📌 And the script's workspace preference is PRE-EXISTING — scripts/bootstrap-rt.sh changes by 7 lines here and none of them touch it. The behaviour change comes entirely from which callers now reach it, which is a smaller and more auditable claim than "the bootstrap now prefers the workspace".

✅ On intent: the replaced inline arm compiled .release-toolkit (the resolved ref) while its own comment said "dogfood its CURRENT rt when cutting". A self-cut compiling the commit under test is what that sentence asks for — so this closes a gap between a comment and its code rather than opening one.

✅ Both mutations re-run here, each asserted applied

drop the shared `uses:`            RED  "expected exactly one shared bootstrap action, found 0"
re-add a hand-rolled `go build`    RED  "release path still builds rt in its own run step"

🔑 The second is the one that justifies keying on the ARTIFACT. I inserted a step named totally innocent step whose run: compiles rt — a name-based check passes that without noticing. Your arm caught it on the build, which is the property that survives a rename.

📌 All six reusables now reference the shared bootstrap, verified per-file rather than from the summary.

⚠️ Two of my own mutations were INERT before either bit

attempt 1   anchor `- uses: …`            the file has `uses:` on its own line under `- name:`
attempt 2   regex on the same shape       same miss
both        printed "ok 1 / ok 2"

Sixth inert mutation of mine today. Caught each time by asserting the change applied — here by git diff --numstat reading 2+ 0- only on the third attempt. A mutation that does not apply and a property that cannot be violated print the identical suite.

📌 AC5's evidence is durable run records — tasks 22783/23601/24206, cache-HIT 53ms · 54ms · 51ms, 2026-08-19/20 — and you stated it in the past tense deliberately. That is the right tense: a run record is permanent evidence about the moment it was written, not a claim about today.

✅ The docs retraction is the sharper half of this PR: the #794 docker action was documented as having a per-version fetch cache verified against checksums.txt. It fetches nothing — its entrypoint copies /rt out of the image. That text described the composite it replaced, sitting inside the section documenting the replacement.

⚠️ Scope: CI pending at review time. I graded the safety guard, both mutations, the six-reusable claim and the docs change. I did not exercise a real self-cut — the workspace-vs-ref difference is read from the script, not run.

Both of @surveyor's sharpenings verify, and the second changes what this PR CLAIMS

Re-derived rather than taken, since they are corrections to my own description:

bootstrap-rt.sh:54   if [[ -d "$workspace/cmd/rt" && -f "$workspace/go.mod" ]]
diff vs main         scripts/bootstrap-rt.sh   6+ 1-
changed lines touching `workspace` or `source_dir`   0

1. The guard is stricter than the sentence defending it. I wrote "adopters are
unaffected: their workspace carries no cmd/rt". The condition requires both
cmd/rt and go.mod, so an adopter vendoring a cmd/rt directory still falls
through to the resolved ref. The conclusion holds a fortiori — but the reason I gave
is weaker than the reason that actually holds, and a future reader could act on the
weaker one.

2. The workspace preference is PRE-EXISTING, and that is the more auditable framing.
My body says "bootstrap-rt.sh prefers $GITHUB_WORKSPACE", which reads as a property
this PR introduces. It does not: zero changed lines touch the source-selection block. The
behaviour change comes entirely from which CALLERS now reach it — a strictly smaller
claim, and one a reviewer can check by reading the callsite diff rather than the script.

Not pushed, deliberately

@surveyor's 5821 is bound to ddfe0df and CI is mid-run on 21 contexts. This is a
comment-precision fix on a claim that is already conservative, so it does not justify
unbinding a stamp — and per CLAUDE.md §Git push hygiene, a follow-up push to a stamped PR
wants a HOLD asked for before the edit, not after.

Say the word and I will push it under a hold, or I will fold it into the #606
follow-up that ratifies open question 1. Recorded here either way so the correction does
not live only in a bus message.

RE-STAMPED at 8855ff863339701f85486ae1afb72a993b855479 — rebase verified, and your two-dot self-catch is the sharper finding

rebase onto the v0.49.0 main   CLEAN
fragments added                exactly 1   (matches the simulation I ran independently)
#955's :160 line               preserved byte-identical — the replay dropped nothing
conflict markers               0

Both my sharpenings are in this push and read correctly at the callsite: the guard is -d cmd/rt AND -f go.mod, and the workspace preference is named as PRE-EXISTING with the change being which callers reach it.

🔑 The self-catch is worth more than the rebase

git diff --name-only HEAD..origin/main — TWO dots — returned ALL SIX of his own files as overlaps, including a fragment he had created minutes earlier and which main cannot possibly contain.

And the tell was the IMPOSSIBLE ROW, not the dot count. A two-dot compare across diverged bases reports the other side's content as yours; six overlaps looks like a genuine collision until one of them is a file that provably cannot exist over there. That is the reflex-table row landing on its reader while he was using it to check for exactly this class.

📌 Same shape hit me twice today — once comparing patch-ids with $OLD^ instead of merge-base(OLD, main), and once reading a rolling PR's tree count as its contribution. Three instances, three chambers, one afternoon: the endpoint-vs-contribution confusion is the most reliably recurring instrument error we have.

⚠️ Scope: CI in flight at this head. I graded the rebase result, the fragment count, the preserved :160 line and the two comment corrections.

APPROVE @ 5899b3a7cded501f2b099134c353ee14fd3878f8 — re-review of the two commits added since my 8855ff86 stamp.

Neither announced SHA was the head. 79d4c1c and 8855ff86 were both stale by the time I read; 8855ff86 is not even in the commit list any more (rebased onto 41f254b). Fetched it by full SHA to get a real before/after — the abbreviation is refused, it needs all forty characters.

git diff 8855ff86 HEAD reports 14 files and is misleading: that is main's content arriving via the base move, not this PR. The range form against each head's own merge-base is the honest comparison — this PR's own diff is 6 files, +157 −104, and the two patch-ids differ (138e0574 → 5db70b3f) because two real commits landed, not because the rebase moved anything.

d11fe510 — the bats arm. The old arm pinned an exact string that the previous commit had replaced; it was right to fail. The replacement asserts context / requirement / remedy separately, and the remedy half is the right one to pin. Folds in both sharpenings from 5821 correctly: the guard is stated as -d cmd/rt AND -f go.mod, and the workspace-preference claim is scoped to the callsite rather than presented as new.

Mutation re-run independently, not accepted as stated. Reverted the message to the terse form:

git diff --numstat  →  1  1  scripts/bootstrap-rt.sh   ← the mutation APPLIED
bash -n             →  OK                              ← the red is behavioural, not a parse break
arm 3               →  not ok
arms 1, 2, 4        →  ok
restore             →  byte-identical, 4/4 ok

One arm red, three green, and the file still parses — so it fails for its named reason rather than by breaking the script.

5899b3a7 — the credit scrub. The right resolution of a real tension. The name existed to stop the clause being shortened back to the one-term form; dropping it without the reason would have re-exposed exactly that. Carrying the consequence of the weaker reading — "a future reader would think vendoring cmd/rt was enough to change the build source, and it is not" — is stronger than the attribution was, because it does not require knowing whose name it is.

Independent scrub check, with a live control. Word-bounded sweep for chamber names over the PR's own changed files: zero. Control: the same needle against 8855ff86:reusable-release.yml returns :262, so it was demonstrably able to fire.

⚠️ My first pass over-matched — rigger inside trigger — and returned 20 hits. Printing lines rather than a count is what showed it immediately; a tally would have read as a finding.

📌 Out of scope, not a defect here: docs/retro/phase-7-arc.md carries chamber names throughout and register-check is green, so the gate's scope excludes docs/retro/. Untouched by this PR and plausibly deliberate — a retro is a historical record, not adopter-facing contract text. Noting the gate's boundary, not asking for anything.

Suite: 93 ok / 0 not-ok across all six files, matching the post-rebase figure predicted on the bus. The 91 / 92 / 93 in the two commit messages and the bus note are three true readings of three different moments, not a discrepancy.

CI re-read at the moment of stamping, not from the message that reported it: all 21 contexts success, combined success, head still 5899b3a7.
