@codex-reviewer-andresmgsl, and he linted the published snippets DIRECTLY,
which my "parse, lint clean" claim had never meant.
1. THE CHECKER DID NOT CHECK THE TARGET. It accepted <fork> <code-sha>
<armed-sha> and used none of them — SC2034 on all three, which is the same
defect the linter and the reviewer found independently. It proved only
"tree equals manifest", so a manifest generated with the ARMED sha where the
candidate belonged, against a tree rewritten to that same wrong value,
passed. Wrong-but-consistent is exactly what this gate exists to reject.
Each manifest `want` is now validated against the independently supplied
target before the tree is compared to it.
2. ONE ORDER, NOT TWO. Step 2 said "commit the arming AND write the manifest"
while the prose below correctly said to generate from the PRE-arming tree.
The manifest enumerates the carriers that must CHANGE, so it has to see them
before they do — generating afterwards enumerates rewritten rows and loses
the canonical internal-checkout ones entirely. The generator's first
parameter is <candidate-checkout> now, and says so.
3. THE SNIPPETS LINT CLEAN STANDALONE. SC2016 needed a scoped directive — and
the first placement was itself invalid: SC1124, a directive may precede a
complete command, not an individual case branch. The checker's mktemp gets
a trap.
Driven, the new controls:
correct manifest + tree + target args passes
wrong fork, manifest AND tree consistent refuses
wrong candidate sha, consistent refuses
armed sha where the candidate belongs refuses
plus every earlier class still red, and both snippets ShellCheck-clean when
extracted as an operator would copy them.

@codex-reviewer-andresmgsl drove the published commands again and found three.
1. THE GENERATOR ABORTED ON AN ABSENT CALLER CLASS — the same `set -e` +
`git grep` no-match bug I had just fixed in the CHECKER, in the generator I
wrote in the same commit and did not apply the lesson to. A probe that
exercises one layer produced no manifest and no diagnostic. `|| true` on
every extraction, plus an explicit count so ZERO ceremony callers refuses by
name while workflow-only and action-only probes generate valid manifests.
That count check was itself broken on its first write: `grep -E '\t…'` reads
a literal `t`, not a tab, so it counted zero on a perfectly good manifest
and refused it. Found by running it.
2. CALLERS CARRY THE COMPLETE COORDINATE. The manifest stored only the sha and
the checker compared owner and suffix separately, so
`<fork>/actions/WRONG-ONE@<right-sha>` passed. The manifest now records
`<fork>/<path>@<sha>` and every kind is one exact comparison — which also
removes the per-kind branch that made the omission possible.
3. GENERATOR AND CHECKER SHARE ONE DOMAIN. `actual` extracted every `uses:`
while the generator manifested only ceremony patterns, so a legitimate
`actions/checkout` was always an unrecognised carrier. Both are restricted
to ceremony callers; a wrong OWNER is still caught because
`wrong-owner/ceremony/...` is still a ceremony caller.
And the stale fragment wording, which glm flagged and codex re-flagged:
"both CEREMONY_SELF_REF values" -> "every".
DRIVEN, all of it:
generator: both / workflow-only / action-only -> valid manifests
generator: zero ceremony callers -> refuses by name
deletion, role swap x2, wrong owner, wrong sha,
wrong path, deleted caller class, extra carrier -> all refuse
armed control, third-party actions/checkout present -> passes

@codex-reviewer-andresmgsl's four holes and @glm-reviewer-andresmgsl's prose
staleness. Every weaker shape I had written has a hole, and each was found in a
published draft of this file:
"the old literal is absent" a carrier rewritten to the wrong fork
"every extracted value equals X" a carrier that VANISHED
"each value is one of {fork,dynamic}" a ROLE SWAP either direction
"the SHA suffix matches" wrong-owner/ceremony/actions/foo@right-sha
"known callers match" an unrecognised caller, or none
So the arming step generates a MANIFEST — path, kind, full expected value —
from the tree it is arming, and the gate compares actual carriers against it as
a set. All six become one kind of failure: the sets differ. Generated rather
than written into this document, because the carrier set changes whenever a
workflow is added — which is exactly how "both CEREMONY_SELF_REF values" went
stale while main grew a third.
The prose went stale with the snippet, as glm noted: step 2 said "both", and
said "every workflow carrier -> repository:" without excepting the consumer
checkouts. Both corrected.
DRIVEN, not asserted. I built an armed/probe pair and ran every class:
deletion, role swap x2, wrong fork, wrong SHA, extra carrier -> all refuse
the armed control -> passes
Doing that found two defects the snippets would otherwise have shipped with:
* the manifest generator's consumer-checkout line used `\$` inside SINGLE
quotes — an escaped dollar, not the end anchor — so it silently produced a
manifest row with no kind and no value;
* `git grep` exits 1 on no-match, and under `set -e` inside the collecting
group that killed the script BEFORE the comparison. A carrier class that
vanished entirely produced SILENCE rather than a refusal, which is worse
than the hole it was meant to close.

@codex-reviewer-andresmgsl's three, all verified against current main before
fixing.
1. THERE ARE THREE SELF-REF CARRIERS, NOT TWO — labels-sweep.yml:52,
labels.yml:51, release.yml:132. My `[ "$n" -eq 2 ]` came from the
pre-upstream tree, so it would have REJECTED a correctly armed candidate and
told the operator to rewrite two of three, leaving one workflow pinned to
the tag. The gate enumerates from the tree now, with the derivation commands
beside the table so the list is re-checked rather than trusted.
2. NOT EVERY `repository:` BELONGS TO THE FORK. Three are
`${{ github.repository }}` — labels-sweep.yml:69, labels.yml:92,
release-exercise.yml:72 — and they fetch the CALLER's repository. My loop
required every one to equal the fork, which would have rewritten the
consumer checkouts and quietly changed what the probe exercises. Internal
self-checkouts (four) are asserted to be the fork; consumer checkouts are
asserted to stay dynamic.
3. EACH CHECK IS BOUND TO THE TREE IT IS ABOUT — `git -C "$armed"` for the
carriers, `git -C "$probe"` for the callers, instead of depending on the
operator's current directory. And `mapfile` rather than `git grep | while …
fail`: the loop ran in a pipeline subshell, so `fail` exited the subshell
and the gate carried on. Collect first, validate after, under a declared
`set -euo pipefail`.
And the snippet is now executable rather than illustrative: placeholders became
positional parameters, so it parses, is shellcheck-clean, and runs. Driven
against the unarmed tree it refuses with `CEREMONY_SELF_REF=0.6.0` — a tag
rather than the candidate SHA, which is exactly the case it exists to catch.
Publishing a gate that could not run would have been the same defect one level
up.

@codex-reviewer-andresmgsl: absence of the canonical coordinate is not proof of
correct arming. The negative grep stays green if CEREMONY_SELF_REF names a tag,
the ARMED sha, or any other commit; if a carrier was rewritten to the wrong
fork; if an executable carrier lives outside .github; or if a carrier simply
disappeared rather than being rewritten.
So the gate is positive now: every `repository:` must equal the recorded fork,
both CEREMONY_SELF_REF values must equal the CANDIDATE CODE sha (not the armed
one — that is the self-reference this two-layer shape exists to avoid), and
callers must match their layer: reusable workflows the armed sha, composite
actions the code sha.
With a COUNT beside the comparison. `n -eq 2` is the part that catches a
carrier which vanished, which a per-value loop cannot see — the same shape as
counting the call sites a pin is guarding rather than only checking the ones
that are there.
The canonical-coordinate grep stays as a cheap extra rather than as the proof.
Wording, same review: steps 1 and 2 advance the tip of ONE fork branch, so
reset removes that branch, not "candidate and armed branches".

@codex-reviewer-andresmgsl found that the procedure was not executable as
written, and the reason is structural rather than a wording slip.
The candidate's workflows carry `repository: heavy-duty/ceremony` beside
`ref: ${{ env.CEREMONY_SELF_REF }}`, so arming must rewrite them. But
rewriting CREATES A NEW COMMIT, and a commit cannot embed its own object ID. So
a single-layer arming is self-referential: pin the callers to the pre-rewrite
SHA and they load the UNARMED workflows; pin them to the post-rewrite SHA and
you are asking that commit to contain itself. My step 3 asked for exactly that.
Two layers, stated as a table because the distinction is the whole thing:
candidate code SHA the immutable tree under test — actions/, lib/
armed workflow SHA a child commit whose workflows point at the fork and
whose CEREMONY_SELF_REF is the candidate code SHA
And callers pin by layer, because they are not the same thing: composite
actions to the candidate code SHA, reusable workflows to the armed SHA, which
is the only revision whose inner checkout is rewritten.
The completeness check becomes a mechanical non-zero gate — `git grep` for
executable `uses:`/`repository:` carriers over the ARMED tree, exiting non-zero
on any hit — rather than "every remaining hit must be prose". A partial rewrite
does not announce itself: it silently tests canonical main.
The result issue records both SHAs, not one, or a later reader cannot tell
which tree answered.

@codex-reviewer-andresmgsl's three operational corrections.
1. ARMING REWRITES THE COORDINATE. The candidate SHA exists only in the
identity fork, so a stub still saying heavy-duty/ceremony/...@<sha> cannot
resolve it — and the candidate's own self-checkout hardcodes
`repository: heavy-duty/ceremony` beside the ref, so rewriting only
CEREMONY_SELF_REF makes it fetch the candidate SHA from the canonical
repository, where it does not exist. Both halves are now explicit, plus a
grep that enumerates every remaining heavy-duty/ceremony carrier so a
PARTIAL rewrite refuses instead of silently testing canonical main.
2. RESULT ISSUES ARE NOT RESET SCOPE. I had step 6 keep them as durable
evidence and the reset section delete them as stale — contradictory, and
the deleting half would recreate the expiring-log problem the venue exists
to avoid. Reset removes candidate-specific EXECUTABLE state only; result
issues may be closed or relabelled, never deleted.
3. NO UNMEASURED CLAIMS. I wrote that a personal namespace is where "the org's
runner and secrets do not reach". That was not measured — the probe repo was
deleted immediately and established only 403-on-org / 201-on-personal. The
no-workaround rule now rests on what was actually ruled: @andres chose an
ORG-OWNED standing venue, so a personally-owned repo is a different thing
from the one decided on and cannot satisfy #202's acceptance target. If
runner reach matters, it gets measured once the venue exists.

@codex-reviewer-andresmgsl's four gaps.
1. BRANCH UPDATED TO CURRENT MAIN. The commit's parent was pre-#204 dad99dd, so
its green 22-file run did not contain the six test files and rules that
landed with the sync. Merged main in — no rewrite — and re-verified against
the 28-file suite the operator would actually receive.
2. WHO MAY RESET IT is now a section, and it says operator-owned until ruled
otherwise, with content reset separated from archive/delete/admin. The
access policy is set when the repo is created, which is the operator's step,
so the two belong together. Flagged for @andres rather than assumed.
3. AN EXECUTABLE ARMING PROCEDURE replaces "install whatever the probe needs":
fork ref and canonical SHA, caller stubs pinned to it, BOTH
CEREMONY_SELF_REF carriers rewritten, the event invoked recorded by name,
and what reset removes afterwards. It reuses the drill rehearsal's fork-ref
pattern rather than inventing a floating pin, including its rule against
ever creating a tag-shaped branch on heavy-duty/ceremony.
4. THE EVIDENCE CONTRADICTION IS RESOLVED. "Write results into an issue in this
repo" and "no probe touches ceremony's board" could not both be followed in
a file where "this repo" reads as ceremony. The job now writes raw results
into the PROBE repo, and a human carries the issue URL and run number to the
ceremony issue. The probe workflow holds no credential and no code path that
can write to ceremony, which is what makes the two rules compatible.
Placement: the operational contract moves to docs/RUNNER-PROBES.md, with a
short cross-link in drills/README.md beside the disposal rule it excepts — the
exception stays visible where the dangerous habit lives, and neither document
grows a second top-level heading.
