@codex-reviewer-andresmgsl's five points. Three were correctness, and one of
them found that my must-fail cases could not fail.
1. THE OBJECT IS MANDATORY. UNVERIFIABLE-HERE is gone: a missing ref, an absent
object and a non-ancestor are three distinct refusals. The ref is now the
FULL 40-character SHA, and ci.yml fetches exactly that object before the
suite. "Runs offline" means the TEST reads local evidence; it never meant CI
may omit the evidence and pass.
2. THE SCAN COVERS WHAT THE INVENTORY CLAIMS. It walked shell under four globs
and never looked at workflows, .github/labels.conf or drills/ — three
categories the inventory governs. Widened, and it immediately found four
real blind spots on merged main: refs-not-closing's declaration,
labels.yml's inline forge decision, refs-guard.yml's GitHub-only scheduling
and release-exercise.yml's pinned CEREMONY_FORGE. All four are now inventory
entries with the issue that removes them, because a delta location with no
exit is indistinguishable from one nobody noticed. A file that DECLARES a
client is no longer exempt as a "consumer" — only files that merely CALL the
shim are.
3. THE TEETH NOW DRIVE THE GUARD. They asserted the predicates separately and
never invoked no_unlisted, so the guard could have been `return 0` and both
must-fail rows would still have passed. SCAN_ROOT is a parameter now and the
cases build a tree, add an unlisted decider — shell AND workflow, so
coverage cannot regress to the old glob — and assert the real top-level
check fails naming it. Replacing no_unlisted with `return 0` reds five.
4. PATH MATCHING, NOT PREFIX MATCHING. `drills/` accepted `drills-old/x` and
`lib/forge.sh` accepted `lib/forge.sh.backup`. Exact for files, `dir/` for
directories, with both negative boundaries covered.
5. THE IMMUTABLE SHA IS CAPTURED AT FETCH. The runbook now takes
upstream_sha=$(git rev-parse gh/main) once and merges and records that
value. This is not hypothetical: while this PR was in review upstream moved
from 8c3a4d1 to 08e2912, and re-reading gh/main at recording time would have
written a commit this tree does not contain. I caught that by walking into
it.
test/run.sh 29/29; upstream-delta 21/21; shellcheck 0.10.0, actionlint,
changelog-armed clean.

The third child of #197, written immediately after performing the sync it
describes, while the findings are still first-hand.
docs/UPSTREAM-SYNC.md carries the procedure and the six standing resolutions,
each with the issue that decided it, so they are not re-argued every sync. The
parts that are not obvious from the outside, and that the 0.6.0 sync paid to
learn:
* THE AUDIT STEP. `git merge` takes upstream's side wherever only upstream
moved a region, so a function upstream ADDED to a file this tree owns
arrives with no conflict and no question. Reviewing the hunks cannot find
it — four reviewers read the same diff and each found a different subset.
That was eight runtime `gh` call sites in three files and two file types.
* THE SAME MECHANIC APPLIES TO STATE. A resolved region can remove a producer
whose consumers auto-merged, and those consumers degrade to empty rather
than erroring, so nothing goes red. Three such seams in one sync.
* VERIFY WHERE IT RUNS. "Green locally" was wrong three times, for three
different reasons: shellcheck-all lints TRACKED files so a new file's first
lint is meaningless; CI pins shellcheck 0.10.0; and the runner's jq 1.6
exits 0 where 1.7 exits 4 on `jq -e` with empty input — which was not a
test problem but a guard accepting an unreadable read.
* TEST THE MERGE RESULT. Forgejo tests heads, never what two branches produce
together, and two green PRs did produce a red tree in this sync.
* AFTER MERGING, CHECK THE SWEEP RECONCILED SOMETHING. The first post-merge
run was green and had done nothing.
.upstream-ref records the carried commit in machine-readable form beside the
CHANGELOG's prose. test/upstream-delta.test.sh asserts every forge-DECIDING
file is named in the inventory — offline, comment-aware, and refusing rather
than skipping when the ref is missing. Shim CONSUMERS are allowed by name, so
a seventh consumer is silent and a seventh decider is not.
docs/CONSUMERS.md now states that two ceremonies answer to the same version
number and how a consumer says which one it pinned.
Must-fail, both from the issue's test plan: scattering a forge_detect branch
into an unlisted file reds the guard; blanking .upstream-ref reds it too.
test/run.sh 29 files 0 failed under jq 1.7 and jq 1.6; shellcheck 0.10.0,
actionlint, self-ref, marker, vendored and changelog-armed all clean.
