Closes #1138.

That issue is a grouping one and proposes no fix, naming only what a fix would have to address: the ordering, "whether hub canonical content can be put in front of a reviewer here, in full, before a downstream repository is the one to find it." This is that mechanism.

The mechanism

scripts/canonical_review.py reproduces the carrier's read in the repository that can act on it, and keeps a record of which content has had one.

A unit is what a reviewer reads whole. One level-two section of a Markdown canonical, one file otherwise. That is the fidelity unit spec/section-model.md already declares and the unit key spec/divergences.json already uses (<path> > <section>). Splitting by section is what keeps the read proportionate: a reviewer asked for all 84 KB of GOVERNANCE.md on every edit reads none of it.

A file the manifest carries by named sections contributes exactly those, so the two sections GOVERNANCE.md keeps for itself are not units, and an interface entry contributes none at all since its body is the carrying repository's own. The skills tree is keyed at .agents/skills/, where a fix lands, rather than at the generated .github/skills/ the manifest names.

Coverage is over content, never over a commit. A unit is covered while a recorded pass names its current digest, so editing it retires the pass and editing its neighbor does not.

The gate is on what a branch changes; the backlog is reported. check refuses only the units this branch's own diff moved, measured from the merge-base. The 283 units nothing has read here yet are a burn-down in reports/canonical-review.md, the way reports/divergences.md carries fidelity, rather than a block on unrelated work.

Where it binds

  • .husky/pre-push runs it beside local_review.py. Both gates run before either verdict is read, so one blocked push names every reason it was refused.
  • The hub's own .github/actions/validate hook runs the same check on every pull request. That is where it actually binds, since a hook a push can bypass raises the cost of skipping the rule without settling it.
  • GOVERNANCE.md "Verification Discipline" carries the rule, AGENTS.md routes to it, and the local-strict-review Skill gains "The Carried-Content Pass" with the brief, the commands, and a refusal-table row.

Dogfooding

The six units this change itself moves carry recorded passes. That pass raised eleven findings, every one fixed here, including a frontmatter lede that undercounted the skill's passes, a refusal table that claimed to be the fleet's one enumeration while missing the new shape, and a brief pointing at a unit "named below" that nothing below named.

Verification

  • python3 -m unittest discover -s scripts/tests: 1012 tests pass, 45 of them new.
  • Each new guard was watched failing: seven mutations (fence awareness, fidelity selection, the declared-section restriction, the cat-file payload offset, the record digest binding, the headless-reviewer refusal, the path containment check) each fail the case that names them, and the suite is green with them reverted.
  • ruff check, ruff format --check, mypy, prose_lint.py (CI's nine checks), repo_gate.py, spec/validate.py, build_dist.py --check, and the four self-test suites all pass.
  • docker_lint.py: editorconfig-checker, actionlint, markdownlint, cspell, shellcheck, and shfmt all clean. PSScriptAnalyzer could not install its module in the container ("No repository with the name 'PSGallery' was found"), which is an execution boundary rather than a result; no .ps1 file is touched by this change.

One disclosure: this session was instructed not to spawn subagents, so both the diff pass and the six carried-content passes ran inline in the main session rather than in the delegated subagent the skill prescribes. They are recorded as agent-skill, which is that backend's kind.

Summary by CodeRabbit

    • Pre-push validation now blocks pushes when required reviews are missing, outdated, or unavailable.

…d It

Hub-owned content under .agents/skills/, GOVERNANCE.md, WORKFLOW.md, AGENTS.md
and AUDIT.md is written and merged here against a diff of a few lines, and only
ever reaches a reviewer as a new file, in full, when a downstream repository
carries it for the first time. So the first real read of a rule happens in the
one repository that cannot act on it: the tree is manifest-owned, the copy is
digest-compared, and a local edit there is drift on the next fidelity check.
Every carrier after that re-discovers the same defect, and the finding arrives
in a session holding no hub checkout and no standing to test the claim.

scripts/canonical_review.py reproduces that read here. A unit is what a reviewer
reads whole, one level-two section of a Markdown canonical and one file
otherwise, matching the fidelity unit spec/section-model.md declares and the
unit key spec/divergences.json already uses. A file the manifest carries by
named sections contributes exactly those, so a section this hub keeps for itself
is not a unit. Coverage is keyed on content rather than on a commit, so editing
a unit retires its pass and editing its neighbor does not.

The gate is on what a branch changes. check refuses only the units this branch's
own diff moved, measured from the merge-base, so the ordering is fixed going
forward without blocking unrelated work on the 283 units nothing has read here
yet. Those are a burn-down in reports/canonical-review.md, the way
reports/divergences.md carries fidelity. .husky/pre-push runs the check beside
its sibling, and the hub's own validate hook runs it on every pull request,
which is where it binds, since a push can bypass a hook.

The six units this change itself moves carry recorded passes, which raised
eleven findings, all fixed here.

High-Level Assessment

The following are alternative approaches to this PR:

1. Commit-scoped review receipts
  • ➕ Simpler record identity
  • ➕ Aligns directly with branch history
  • ➖ Retires coverage after unrelated neighboring edits
  • ➖ Cannot reuse a valid read of unchanged content
2. Whole-file canonical reviews
  • ➕ Simpler Markdown parsing
  • ➕ Fewer ledger keys
  • ➖ Makes large canonicals impractical to review repeatedly
  • ➖ Couples unrelated sections and encourages superficial reads
3. Downstream-only review enforcement
  • ➕ Reviews the exact carried files
  • ➕ Requires no hub coverage ledger
  • ➖ Findings arrive where canonical content cannot be edited
  • ➖ Repeats the same defects across every carrier

Recommendation: Keep the PR's section-or-file unit model with digest-bound coverage. It preserves review fidelity while limiting rereads to changed content, and enforcing it in both pre-push and PR validation closes the bypass gap without making the existing backlog block unrelated work.

cost with the hub whose hook this is instead of on every repository that reuses
that workflow.

Action required

1. PR base history unavailable ✓ Resolved 🐞 Bug ☼ Reliability
Description
The PR action passes the base SHA to canonical_review.py, but the validate job checks out only the
triggering commit at checkout's default depth of one, so the base commit and merge history normally
do not resolve and every PR canonical check exits 2 instead of producing a coverage verdict. This
makes the new authoritative capture point fail before it can gate changed units.

The added action supplies base.sha, while the reusable validate job invokes actions/checkout

2. Newly carried content bypasses ✓ Resolved 🐞 Bug ≡ Correctness
Description
changed_units() applies the current manifest's carried set to both HEAD and the base commit, so
adding an existing file, section, or tree path to spec/files.json yields identical base/current
digests and no changed unit. The branch can therefore make previously unreviewed content available
to downstream carriers—the exact first-read case this gate targets—without requiring a pass.
Code

scripts/canonical_review.py[R468-472]

+    carried, absent = carried_paths(root)
+    found, missing = build_units(carried, disk_reader(root))
+    current = {key: digest(text) for key, text in found.items()}

3. Carried-content rule duplicated ✓ Resolved 📘 Rule violation ⚙ Maintainability
Description
local-strict-review restates the carried-content rule's conditions, rationale, unit definition,
and obligations instead of only routing readers to GOVERNANCE.md. This creates another substantive
copy of a cross-cutting rule that can drift from its canonical definition.
Code

.agents/skills/local-strict-review/SKILL.md[R87-89]

+A second pass under the same rule, run in the repository that authors canonical content other repositories carry, which in this fleet is the hub. It answers an ordering defect rather than a quality one. Such content is written and merged against a diff of a few lines, and reaches a reviewer as a new file, in full, only when a repository carries it for the first time, so the first real read of a rule happens where nothing can be done about the result: the tree is manifest-owned, the copy is digest-compared, and a local edit there is drift on the next fidelity check. Every carrier after that re-discovers the same defect, and the finding arrives in a session holding no checkout of the authoring repository and no standing to test the claim.
+
+**The unit is what a reviewer reads whole**, one level-two section of a Markdown canonical and one file otherwise. The pass reads that unit's whole current text rather than the diff that moved it, because reproducing the carrier's read is the entire point, and a diff with surrounding context is a different read that has already been done by the pass above.

4. Recorded pass dirties push ✓ Resolved 🐞 Bug ≡ Correctness
Description
The documented commit-review-record-push order cannot complete cleanly for canonical reviews because
record writes the tracked ledger after the commit, while pre-push rejects any tracked difference
from HEAD before running either gate. Users following the new instructions are necessarily blocked
and must commit the ledger and rerun the diff review, a required sequencing step the procedure
omits.
Code

GOVERNANCE.md[250]

+- **The hub carries a second hook, `.husky/pre-push`, gating the local-review rule rather than lint.** It runs `scripts/local_review.py check` and `scripts/canonical_review.py check`, refusing a branch push whose diff no recorded review pass covers and one whose changed canonical units none covers, per "Verification Discipline" above. Both run before either verdict is read, so a blocked push names every reason it was refused rather than only the first, which would otherwise cost a second push to discover the next. It fires only for a branch update, so a tag push and a branch delete pass through, and a branch holding no net content against its target has nothing for a review to cover. It refuses rather than guesses in every state it cannot speak for, since the engine reads the checkout it runs in while a push delivers a commit, and those describe the same content only sometimes. The order that keeps them describing the same content, and the one every capture point is built around, is to commit, then review, then record, then push. It reads `develop` and accepts no override from the environment, since an environment variable is set inline on the very command being gated, by whoever is being gated, which is the same reason an authorization is never read from a channel the agent itself can set. The cost is that it measures a branch based on anything but `develop` against `develop` anyway, so its refusal there is not a verdict about that branch. Each refusal names its own case, and the `local-strict-review` Skill carries the fleet's one enumeration of them with what clears each, deliberately in one place rather than restated here. It folds the engine's three-valued exit honestly: a check that could not run blocks too, and says so in different words than a check that ran and found no pass, because a gate that waves a push through when it could not run is a gate that stopped gating. It is a backstop rather than a seal, and it is bypassable by construction: `--no-verify` is the documented route out of a pickle and is not the only one, since a git hook cannot police its own invocation. A Claude Code session meets a narrower surface, that flag being denied unconditionally by the agent-safety hook's explicit-bypass rule, and that denial is Claude Code's alone, since Codex and opencode carry no such hook yet. So the committed hook raises the cost of skipping the rule for one agent and lowers it for none, and the prose layer above stays the agent-agnostic one that actually binds. It is hub-only for now. `local_review.py` and `canonical_review.py` are both hub-hosted per "Hub-Hosted Tooling", and a downstream repo reaches either as a hub checkout's copy run with its own worktree as the working directory, so a catalog snippet carrying this hook fleet-wide is a later step rather than part of this one. The canonical-unit half is also run by the hub's own `.github/actions/validate` hook on every pull request, which is where it actually binds, since a hook a push can bypass raises the cost of skipping the rule without ever settling it. That step is scoped to a pull request because a unit's change is measured against the branch it is proposed into, and a push carrying no pull request names none.

canonical_review.py record rewrites the tracked JSON ledger, but the hook exits before either

Disposes of the nine findings the pull request reviewers raised. Six were real
and are fixed: a case for the --target <sha> form validation actually passes, a
needless __future__ import, a spaced hyphen in generated prose, a burn-down that
went stale on every record, and two bugs.

The first bug: changed_units applied this branch's manifest to both sides, so
adding an already-present file or section to spec/files.json produced identical
digests and no changed unit. Content became newly carried, every downstream repo
read it for the first time, and the gate built for that case said nothing. The
base is now resolved against the base commit's own manifest.

The second: the documented commit-review-record-push order cannot complete,
because record writes tracked files and the pre-push hook refuses a tree
differing from HEAD before either gate runs. The constraint is that the ledger
and burn-down are committed before the push while the diff receipt is recorded
after the last commit, and three files said otherwise.

One finding is declined. The claimed one-line comment policy does not exist:
CODESTYLE.md states no such rule, prose_lint's rule is one sentence per comment
line rather than one line per block, and origin/develop's copy of that same file
already carries a four-line block.

Eight delegated local-strict-review passes over the four carried units this
change moves then raised 39 more findings that no reviewer had. Thirty are fixed
here, including a crash path that exited 1 where a capture point reads 1 as the
not-covered verdict, reporting an execution boundary as a gate finding. Eleven
are pre-existing defects in units this change only touches, filed as #1149 and
#1150 rather than folded in.

Nine findings from a delegated diff pass, each reproduced rather than reasoned
about.

The carried set now comes from git on both sides. The tree half walked the
filesystem while the base half read git's tree, so the two compared different
notions of membership, and anything sitting in a carried directory counted as
canonical content: a gitignored .DS_Store failed the UTF-8 decode and took every
subcommand to exit 2, blocking every push from that clone. Tracked plus
unignored is the set, so a new unstaged canonical is still covered.

Tree membership now comes from the tree a repository receives and the key from
the tree a fix may edit. .agents/skills/README.md exists only on the authored
side, so the gate had been demanding a carrier's read of a file no carrier gets,
the obligation this tool must not invent.

cat-file --batch answers are keyed on the last field. git echoes the request
verbatim, so a path holding spaces pushed a digit into third place and the next
answer's header was returned as that path's content. The call also inherited the
git redirects every other call here strips, where GIT_OBJECT_DIRECTORY reads as
a base that carried nothing, and encoded names without surrogateescape.

Declared section names match case-folded, as spec/audit.py already does, so a
re-cased declaration no longer stops gating a section while reporting it as not
held here. report --check is the burn-down's own gate, on build_dist --check's
contract, and runs unconditionally in CI.

Deferred: #1151, record having no lock, which fails closed.
Three findings from a second delegated diff pass.

The declared-name lookup folds case while file_units' duplicate guard did not,
an asymmetry the previous commit introduced. Two headings differing only in case
passed the guard, the dict kept the last, and spec/audit.py's own match keeps the
first, so a pass would have been recorded over one section's bytes while the
fidelity check hashed the other's, and the first section would have been no unit
at all. Latent rather than live: no carried file holds such a pair today.

A refusal raised while reading the merge-base named only a path, so a duplicate
heading a later commit removed reported a defect in the file the reader is about
to open, which does not hold one. Those now name the commit.

report --check ran in CI and appeared in no runbook, so its failure shape had
nowhere to be looked up. It is in OPERATIONS.md's own "the gates the way CI runs
them" block and in scripts/README.md now.

Also covers the symlink refusal disk_reader gained, which no case exercised.
Three text findings from the pass that covers this push. None is in a carried
unit, so no recorded pass is retired.

Both runbooks said a renamed or deleted unit leaves check covered while only
report --check notices. Deletion does. Renaming does only for a file the
manifest carries by named sections, meaning AGENTS.md and GOVERNANCE.md, where
the declared name then matches no heading. Renaming a section of a file carried
whole makes check name the new unit and demand a pass, so the claim was false
for every other carried unit, which is all 200-odd of them.

The duplicate-heading refusal named only the second spelling, exact before case
folding and not after, so a reader searching for the name printed found one of
the pair. It names both where they differ.

A test docstring credited file_units with keeping the last of a case-colliding
pair. Unfolded it keeps both, and the lookup that resolves a declaration to one
of them is build_units', which is what the fold protects.

Recorded pass dirties push Fixed, 2ebd480

The Qodo open finding that carries no thread is Validate comment block too long, answered in its thread and summarized here so it is answered where it was raised: the cited one-line comment policy does not exist in this repository, prose_lint.py's rule is one sentence per comment line rather than one line per block, and origin/develop's own copy of that file already carried a four-line consecutive block before this pull request touched it.

Two findings were real bugs rather than style, and both are worth naming.

Newly carried content bypassed the gate. changed_units applied this branch's manifest to both sides of the comparison, so widening spec/files.json to cover an already-present file or section produced identical digests and no changed unit. Content became newly carried, every downstream repository would read it for the first time, and the gate built for exactly that case said nothing. The base is now resolved against the base commit's own manifest.

The documented order could not complete. record writes tracked files and the pre-push hook refuses a tree differing from HEAD before it runs either gate, so commit-review-record-push deadlocks. The rule now states the constraint, that both tracked files are committed before the push while the untracked receipt is recorded after the last commit, rather than one mandated sequence.

What the local passes then found

Eleven delegated local-strict-review passes ran against this branch, eight over the four carried units it moves and three over its whole diff. They raised 55 further findings that no pull request reviewer raised. Forty-four are fixed here. Eleven are pre-existing defects in units this change only touches and are filed rather than folded in: #1149 and #1150 for prose, #1151 for record having no lock, which fails closed.

Three of those were correctness bugs in the engine:

  • git cat-file --batch echoes the request on a missing line, so a path holding spaces pushed a digit into third place and the next answer's header was returned as that path's content. Reproduced before fixing. Now keyed on the last field.
  • main() caught only CannotRun, so an OSError or TimeoutExpired out of blobs_at fell through to exit 1, which a capture point folds as "this push is blocked, which is the gate working" — an execution boundary reported as a verdict, in the tool whose own refusal table promises otherwise.
  • The carried set came from a filesystem walk on one side and git's tree on the other, so a gitignored .DS_Store in a carried directory failed the UTF-8 decode and took every subcommand to exit 2, blocking every push from that clone.

Worth stating plainly: the majority of those 55 were defects introduced while fixing earlier ones. The unit-model sentence was wrong in four consecutive rounds, each time in a new way, before the paraphrase was cut entirely in favour of pointing at canonical_review.py list. That is this repository's own recorded lesson, that cutting text beats qualifying it, and it took four rounds to apply.

All four carried units this change moves carry recorded passes at their current text, and the branch's diff carries a recorded receipt.

The burn-down step carried no if:, so the implicit success() skipped it whenever
an earlier step in the composite action failed. CI therefore reported the first
reason a run was refused and hid the next, which costs a whole round to
discover, and which is the reason .husky/pre-push runs both gates before reading
either verdict. The two disagreed and the hook was right.

!cancelled() rather than always(): the latter also runs after a cancellation,
where nothing is waiting for the answer, and GitHub's own expressions reference
names !cancelled() as the recommended alternative. The ${{ }} wrapping is
required rather than stylistic, since ! is reserved notation in YAML.

Both prose surfaces called the step unconditional, which it no longer is.

Note for a later reader: no linter here validates this expression.
scripts/docker_lint.py scopes actionlint to .github/workflows/*.yml, and CI's
actionlint step uses the same default, so .github/actions/**/action.yml is
covered by neither.
