Two pieces, one branch: the first census movement of the bash-retirement campaign, and the caller the board gates never had.

1 — run-shape-guard, partially migrated (CLOUD-843 track 2)

One of five families moved. The dispatch describes this guard as the campaign's free start — "otherwise pure string analysis of command, which the envelope already carries" — and measured against main that holds for exactly one of its five predicates.

family state blocked on
foreground-sleep bash run_in_background is not in call_document — reachable only through hook::Field. CLOUD-613
background-timer bash same fact, same row
unsatisfiable-commit bash heredoc binding, which nothing in the engine models. CLOUD-613
commit-names-no-message-source migratedpolicy/run-shape.rego
cargo-substitutes-for-a-task bash call_document projects Fact::Document as None. CLOUD-856

The guard is not deleted — it still owns four — and that table is now in its own header, where a reader who opens the file finds it.

Verified by negative control, not by a green policy test

CLOUD-845 establishes that a module can pass its own suite and gate nothing. So tests/run-shape.bats drives the compiled binary over a real PreToolUse envelope in a throwaway fixture repository, replaying the retired arm's own corpus and asserting both verdicts — 27 differential controls during development against the bash guard, 13 cases kept.

mise run mutant resolves a .rego subject as well as a shell task now, because a migration that could not declare a mutation would shrink the enforced set while reporting the census going down. Four declared, every one caught; three corrupt the scrubbing and the splitting rather than the flag table, which is where a raw-string module goes quietly wrong. It caught a fifth that could not discriminate, and that fix is its own commit rather than smoothed away.

The census moved the wrong way, and that is the deliverable

~420 lines added to retire ~20 — roughly 20x the estimate the campaign's framing carries. 225 of them are a heredoc-body drop, a quoted-span scrub and a list split written in Rego with core builtins, because input.call.command is the raw string and this build of regorus carries no regex feature. The full delta is on CLOUD-843.

2 — mise run board-sweep (CLOUD-825)

The seven board gates already compose. What was missing is a caller: two of the three roots were never pulled, and released — wired into release-plz.yml on every tag — is invoked </dev/null, which takes its refs-only arm and returns before the graph-check invocation. The composition exists, is wired, runs, and is handed nothing to decide over.

This is that caller and nothing else: every gate is invoked by path with JSON on stdin and its exit code read as the three-valued channel it publishes. Every gate runs; the report is a set, not a first failure. Could-not-look outranks a refusal and is never laundered into its lane. Effect is read — it moves no row, and there is no schedule (CLOUD-825 §5 defers that deliberately).

Three things the fixture run turned up, each now a case:

  • The report has to read both streams. These gates disagree about which one carries a finding, and released puts its per-issue verdicts — including REFUSED (<rule>), the only place graph-check's answer surfaces at all — on stdout.
  • The payload source is chosen before anything is read. [ -t 0 ] does not work here: a task-runner call has no tty on stdin whether or not anything was piped, so a bare invocation blocks on a stdin nobody will close.
  • The anti-vacuity verdict must be the composer's own. Asserting only the exit code could not discriminate the mutation — without the guard, released chokes on the empty set and exits 2 by itself, for a reason that has nothing to do with having noticed.

The invocation budget, and a threshold overridden deliberately

perf-gate refuses this branch, and it is not wrong to: wired goes 6.91ms ->
10.1ms against the merge base, 1.462x on a 1.30x threshold whose noise floor is
a measured 1.102x. Isolated locally by toggling only the row, same binary:

module wired
none 5.8 ms
trivial, one rule 6.2 ms
this predicate, tests removed 7.7 ms
this predicate with its 4 tests 9.3 ms
the same predicate against a projected input.call.segments 6.8 ms (1.17x)

The cost is COMPILATION, not evaluation — policy::load compiles every
registered module on every mediated call. A cheap pre-filter ahead of the
analysis changed nothing; neither did stripping comments. What moves the number
is how much module there is to compile, and ~15 of this module's rules exist
only to scrub and split a raw command string the engine already parses.

Landed over the gate on an explicit, committed, expiring decision. CI cannot
see an env override exported for one local run, and raising the default 1.30
would answer a one-branch question repo-wide while recording nothing. So
perf-compare gains an acceptance table — path|ratio|expires|reason — and one
row. Scoped to wired, so hook, check and noop are still judged at 1.30;
bounded at 1.60, so past that is refused like anything else; expiring
2026-11-30, and a lapsed row stops exempting rather than quietly continuing;
carrying its reason; and printed on every run, because an accepted regression
that stops being visible is a raised threshold with extra steps.

Stated plainly, because it is the uncomfortable half: the ratio compares two
different amounts of enforcement — this branch gives the ENGINE a predicate it
did not have — but run-shape-guard was already enforcing it in bash and still
runs with its other four families, so the system now does that job in two
processes rather than one. The gate is measuring something real.

The last row is why that is temporary rather than a new normal, and it is a
measurement rather than a hope: with CLOUD-857's projection this module is five
rules and lands at 1.17x. That makes CLOUD-857 a hard blocker on wave 1, not
an adjacent improvement, and it is the single most useful thing this branch
found.

Filed rather than fixed

  • CLOUD-856Fact::Document is None on the mediated call, so the cargo family has no surface. CLOUD-613 names only two of that guard's three blockers.
  • CLOUD-857 — the vendored no-force-push preset is silent on every compound command (cd /tmp && git push --force is allowed) because it anchors words[0] == "git" over the whole line, and its own tests only ever pass a bare one. It is the file wave 1 copies ~80 times. The fix worth having is projecting hook::segments as input.call.segments, which is Cost::Free and collapses the 225-line module to roughly 40.

Both are outside what this branch was asked to do; both are one measurement away from being wave 1's cost model.

Closes CLOUD-825

DO-NOT-CLOSE CLOUD-843 — this is one wave of a campaign that owns 82 gates; the row stays open and carries the census.

CLOUD-825 The board gates already compose — `released` is fed `/dev/null` and three gates have no invoker, so four of the seven never decide

Why

Board dissonance — the board saying one thing while the tree says another — is not accumulating because gates are missing. Seven exist, every one a pure function of get_issue payloads on stdin:

Gate The dissonance it names
graph-check graph incoherence, a dishonest column, Todo⇒Ready
in-progress-drain In Progress that has landed; abandoned claims
landed-check In Progress while its commits are on main
done-pr-check Done while one of its own PRs is still open
spec-ref-check a CLOUD-N §M citation naming a clause the issue lacks
released In Review that a tag already shipped
ready-lint the Ready block's checkable clauses

Corrected 2026-08-21, before this row was pulled

This issue was filed claiming "zero of seven" and "nothing composes them". Both are false, and the corrected finding is narrower and much cheaper to fix. The error came from grepping for mise run <gate> — which misses a call by path and misses a variable assignment. graph-check:87 reads lint="$(dirname "$0")/ready-lint", and no grep for the gate's name as a command finds it.

They already compose. The chains exist; two of the three roots are never pulled and the third is fed nothing.

chain state
board-write-recordready-lint live — a registered PostToolUse hook on .*save_issue|.*save_comment, piping a projected payload at line 290, on every board write
releasedgraph-checkready-lint the root runs on every tag, with </dev/null
in-progress-drainlanded-check the root has no invoker
done-pr-check, spec-ref-check no invoker at all

claim-check:387 calls ready-lint by path too, so that gate has three callers, one of them a hook.

The defect is one redirect and one missing caller. .github/workflows/release-plz.yml:187 runs:

mise run released "$tag" </dev/null

released's own usage line distinguishes the arms — mise run released v0.0.14 reports the refs a tag shipped, mise run released v0.0.14 < payloads.json restricts to In Review issues. The wired call takes the first, and that arm returns before reaching the graph-check invocation at line 193. So the composition that would sweep the board on every release exists, is wired, runs, and is handed nothing to decide over.

hk.pkl genuinely wires none of them — the three occurrences of these names in it are inside comments. That part stood.

And the reason it is worth filing now is that everything else is already built. Both halves of the fetch side landed on 2026-08-20:

  • board-payloads (CLOUD-782) recovers this session's own get_issue payloads from its transcript, byte-perfect, joined on tool_use_id, discriminating get_issue from save_issue by tool name — so a payload reaches a gate's stdin without an agent re-typing it, which is the forged-compliance shape CLOUD-526 measured seven times.
  • merged-pr-keys (CLOUD-814) emits <CLOUD-id><TAB><pr-number> for merged PRs — the evidence landed-check --merged-prs refuses to decide without, and which its own header records as having been produced by nothing but an ad-hoc /tmp script until that day.

Its header states the split: "THIS DECIDES NOTHING, which is what lets it hold a credential… This is the FETCH side." Both fetch sides now exist, both decider sides exist, and — per the correction above — so does most of the joining. What is missing is a payload set reaching released, and an invoker for the drain, done-pr-check and spec-ref-check.

Why the In Progress column is the evidence, not the anecdote. CLOUD-469 measured that column 39 deep and was closed by building in-progress-drain — the drain, the thing that names what has gone stale. On 2026-08-21 the column is 28 deep and in-progress-drain has never been asked about any of it. A live instance of what it would have caught, from the same day: one merge advanced CLOUD-737, CLOUD-738 and CLOUD-739 to In Review on mere mentions while none of their work was on main, and In Review is what released reads.

That is the shape of the whole defect, and it is non-negotiable rule 2 inverted: the gate is runnable and its caller is feedforward. merged-pr-keys's header already names this inversion for its own case.

Cost, and why one sweep is the affordable shape

CLOUD-782 measured the read: list_issues projects fields but its enum carries neither attachments nor relations, and get_issue returns both and takes no field selection, so a sweep pays ~4.5k tokens per issue to decide on ~1.6k. That ~3x is structural and this row does not touch it.

One fetch, N gates is what makes it affordable — the ~3x is paid once per sweep instead of once per gate, which is the difference between running seven gates and running one seven times. That is an argument for composing them, not a reason to defer.


Refinement — Ready

Refinement gate: Definition of Ready & Done. This body carries only specializations.

  • Source of truth (§1). Each gate stays the one authority on the dissonance it names, and — per the correction above — the composition mostly exists, so this row must not build a second one. A parallel composer beside releasedgraph-checkready-lint would be the CLOUD-351 shape at the caller layer: two sweeps for one board, only the newer one consulted. board-payloads stays the one payload source and merged-pr-keys the one merged-PR evidence source.
  • What the work actually is, stated so it is not over-built. Three things, smallest first: (a) feed released a payload set where release-plz.yml:187 feeds it /dev/null, which reaches graph-check and ready-lint behind it; (b) give in-progress-drain an invoker, which reaches landed-check behind it; (c) give done-pr-check and spec-ref-check one. Whether (b) and (c) hang off the same entry point as (a) or a separate one is an implementation choice, not a second authority — what matters is that no gate's predicate is re-derived.
  • Computable predicate (§2). Over one payload set covering Todo, In Progress, In Review and Done, every gate named above is reached — directly or through the chain that already calls it — and its exit code collected, and the verdict is the disjunction: exit 0 iff every gate exited 0. ready-lint runs per Todo row rather than over the set, because it decides one Ready block at a time. A gate that cannot look — empty stdin, a projected-away field, a capped evidence file — is a problem, never a pass, following merged-pr-keys's own reading that a truncated evidence file under-reports silently and ci-local-parity's could-not-look-collapses-to-a-problem narrowing.
  • The report is a set, not a first failure. A sweep that stopped at the first refusing gate would make the second dissonance invisible until the first was fixed, and the cost model above means the next look is not free. Every gate runs; the report names each refusal.
  • Effect (§3). read. The sweep decides and reports; it moves no row. That asymmetry is the safety property: a sweeper authorised to write would be a board-editing robot deciding from a snapshot, and board-payloads's own header records the failure — "the corrected predicate returned the right relations beside a STALE status" — measured twice on 2026-08-20. Recover structure from the cache; re-read a row before deciding its state.
  • Output & exit (§5). Pointer-only per non-negotiable rule 4 — issue keys, gate names and counts, never a line of a body. Exit 0 clean / 1 dissonance named / 2 could not look, matching the three gates it composes so the whole thing stays one contract with no per-verb exception (house-style §6–§7).
  • Scheduling is a second decision and is deliberately not this row's. What lands here is the composer, runnable by hand. Whether it also runs on a cron, at Stop, or as a land postlude is a trigger question with its own cost — and CLOUD-812 measured 96 idle cron ticks/day flooring at ~2,900 billed min/month, so a schedule is not free and must not be added as an afterthought. Ship the caller; file the trigger.
  • Commit / bump (§6). featpatch until 0.1.0; below that release-plz patches whatever the type says.
  • Test obligation (§7). tests/board-sweep.bats, over fixture payload sets rather than a live board, in the shape tests/ci-local-parity.bats uses. Shown able to fail per CLOUD-418: a fixture set containing an In Progress row whose commits are on main must exit non-zero and name in-progress-drain. Plus the case this row's own correction demands — a fixture set piped where release-plz.yml pipes /dev/null must reach graph-check, proven by a fixture whose only defect is one graph-check names, since that is the exact path the current wiring runs past. Plus: a set with no dissonance exits 0; an empty stdin exits 2 rather than reporting clean, which is the anti-vacuity case and the one a composer gets wrong; a gate exiting 2 is not laundered into the 1 lane; and the report carries no body text.
  • Blockers (§8). None. relatedTo CLOUD-469, whose drain this completes; relatedTo CLOUD-782 and CLOUD-814, the two fetch halves it composes; relatedTo CLOUD-804, which moved half of landedness to the caller and is why a caller has to exist.

Done

main carries the sweep, a fixture set carrying a landed-but-In-Progress row is red where a clean set is green, and CI green on the merge commit landed by fast-forward.

Not in scope

Changing any gate's predicate; the ~3x read cost, which is the tracker's field-projection gap and CLOUD-782's; and the schedule, per §5 above.

CLOUD-843 The retirement campaign has no row: eight capability rows cite "so the 79 gates have somewhere to migrate onto", and nothing owns the migration — measured, the bash grew today

Why

Eight rows in this campaign are justified by a migration nobody owns. CLOUD-833's title is literally "so none of the 79 gate-described mise-tasks has a surface to migrate onto"; CLOUD-832 exists so a bundle can carry 79 predicates; CLOUD-807 built the permit that lets a suite die with its subject. CLOUD-312 owns the 11 hook bodies and only those.

The 82 gate-described mise-tasks/ programs have no owning row. Searched 2026-08-21; the closest hits are all capability rows citing the campaign as their justification. This is DoR §2's own failure mode one level up: the backlog grew the engine, and the thing the engine was grown for was never filed.

Measured on main @ 12cca46 (v0.0.99), against the same census that morning

Surface Morning Now Δ
mise-tasks/ files 133 136 +3
mise-tasks/ lines 27,799 28,590 +791

bats cases 2,485 2,548 +63
gate tasks migrated 0
kind = "policy" rows 0 1 — and it is trunk-based-preset, a vendored preset, not a migrated gate

One bash file was retired all day: .claude/hooks/batten-hook.sh, 65 lines (CLOUD-824). Against +791 lines added. The campaign to delete bash added bash, and nothing on the board was positioned to notice, because no row carries the number.

The classification, by what each task invokes

Not by substring. A string scan over these files put ci-local-parity and pipefail-grep-check in the forge bucket — the same instrument that counted 14 spawn sites where name resolution found 9 (CLOUD-743). Classified instead by the external programs each task actually invokes in command position:

bucket count can it migrate?
tree — no git, no forge, no build 22 yes, on CLOUD-833's tree surface, today
git facts 50 needs a git fact on the tree document; scope unproven
build/bench 3 probably never — they run cargo/hyperfine
forge 7 last, and some may legitimately stay

The 50 is the number that matters and it was not expected: this is a git policy engine, so most gates read git. The "79 gates become Rego rows" framing every capability row inherited is unproven for 60 of the 82. That is this row's first deliverable to settle, not assume.

The pilot

mise-pin-agreement"every tool version named in .mcp.json agrees with mise.toml's pin — the second place a pin is written cannot drift from the first".

Chosen on data: 107 lines of bash, 10 cases, 108 lines of bats — the smallest of the structured-document gates. Both inputs are formats Fact::Document already parses (CLOUD-772: TOML/YAML/JSON/JSON5), and the predicate is agreement between two parsed trees, which is what Rego is for. No git, no spawn, no stdin.

It also carries no #MUTANT directive, so it is one of CLOUD-480's undeclared gates. Migrating it should add a declared mutation — coverage improves as a side effect rather than degrading.

Rejected as pilot: no-docs-tree, which an earlier plan named. It is not a mise-tasks/ program at all — it is a batten.toml rule in the hk gate. Recorded because the name was carried in prose across three documents before anyone checked the tree.

Sequencing, and the one trap

  1. Settle the 50. Determine what a git-fact gate needs on the tree surface. Until then "79 gates migrate" is an estimate, not a plan.
  2. CLOUD-835 lands — the destination for the 1,570 bats cases.
  3. The pilot, end to end, one gate: Rego module, test_ rules, delete the task and its suite, MUTANT declared. The pilot converts the estimate into a measured cost per gate. Do not batch before it.
  4. Waves by bucket, cheapest first.

The trap, and it is new as of today. CLOUD-807 landed retires_with, so a suite may now be deleted exactly when its declared subject dies. That is correct and it was the precondition for retiring anything — but it makes migrating without CLOUD-835 worse, not better. The ratchet will admit deleting a suite whose task died, with nothing asserting the Rego that replaced it. The permit made coverage evaporation quiet. 835 is a hard blocker, not a nicety.


Refinement — Ready

Refinement gate: Definition of Ready & Done. This body carries only specializations.

  • Source of truth (§1). The tree. The census below is the authority on progress, not a burndown restated anywhere; batten.toml owns which gates are policy rows and mise-tasks/ owns which are still bash. No second list of what has migrated.
  • Computable predicate (§2). The census, re-run at every wave boundary:
ls mise-tasks/ | wc -l ; cat mise-tasks/* | wc -l
grep -l '#MISE description="Gate' mise-tasks/* | wc -l
ls tests/*.bats | wc -l ; cat tests/*.bats | wc -l ; grep -h '^@test' tests/*.bats | wc -l
grep -c 'kind = "policy"' batten.toml

A wave that does not move these down has retired nothing, whatever else it landed. That predicate is the whole point of this row existing: today's +791 was invisible because nothing computed it.

  • Effect (§3). read — migration moves predicates between surfaces; no verb is added and no rule kind's Authority changes.
  • Generated artifacts (§4). schema/batten.schema.json only if a row key changes; the per-wave batten.toml rows are authored. derived-check and schema-check gate both.
  • Output & exit (§5). Unchanged — a migrated gate keeps its exit contract, and a Rego predicate reports pointer-only by construction. A migrated gate's refusal text must still name its remedy (CLOUD-437); a msg that lost the remedy in translation is a regression the bats case would not catch.
  • Commit / bump (§6). refactor per wave — no bump. The answers are identical by construction; a wave that changes a verdict is not a migration.
  • Test obligation (§7). Per wave, and the pilot establishes the shape: (a) every case in the retired suite has a test_ rule that fails when the predicate is wrong; (b) the retired task and its suite are both gone, admitted by retires_with because the subject died; (c) the gate's declared mutation is caught by mise run mutant — for mise-pin-agreement that is a mutation it does not have today; (d) the census moves down by the retired count, asserted rather than eyeballed.
  • Blockers (§8). blockedBy CLOUD-835 — see the trap above; without a test destination the permit lets coverage disappear silently. relatedTo CLOUD-833 (the surface, landed), CLOUD-832 (predicate ids, landed), CLOUD-807 (the permit, landed), CLOUD-312 (the 11 hook bodies — the other half of the retirement, and not this row), CLOUD-480 (the undeclared gates a migration should shrink), CLOUD-772 (the document substrate the tree bucket consumes), CLOUD-839 (the capability dispatch that bought the machinery).

Acceptance

  • The 50 git-fact gates have a stated verdict: migratable on a named fact, or not, with the reason.
  • mise-pin-agreement is a policy row; its task and suite are deleted; mutant catches its declared mutation; the census is down by one gate and ~215 lines.
  • The measured cost per gate from the pilot is recorded here, and the waves are sized from it rather than from the count.
  • Every wave re-runs the census and records the delta.

Found while auditing what the CLOUD-839 fleet landed, by asking the question the capability rows never had to answer: how much bash actually went away.


PRESSURE-TESTED 2026-08-21 — wave 1 cannot dispatch yet, and the reason is a run rather than a reading

CLOUD-835 landed (62719ff, v0.0.100), so the blocker in the trap above is cleared and the 1,570 cases have a destination. Before dispatching a wave on that, the path was walked end to end against the release binary in a throwaway git fixture. It does not hold yet.

What the run showed

Two modules in one enabled bundle. One copied verbatim from policy.rs's own module doc; one written against what rules::tree_document actually builds. A stray.o tracked. Each with a test_ rule in the shape the vendored presets use.

$ batten policy test
policy test: 1 bundle(s), 2 passed, 0 failed        EXIT: 0

$ batten check
policy/ msrv-must-be-pinned                          EXIT: 2

The doc-shaped module passes its test and gates nothing. input.tree.tracked is documented at policy.rs:143-147 and never emitted — tree_document builds documents and missing, and nothing else. Rego makes the failure silent: iterating an undefined path yields no violations, so a dead gate and a clean tree are byte-identical. The test_ rule passes because with input as lets the author fabricate the very shape the engine cannot produce.

That is CLOUD-845, and it is a hard blocker on this row rather than tidy-up: every wave-1 agent starts from that doc, and combined with retires_with the failure mode is green tests, silent gate, deleted bash task that used to work. Ten gates migrated that way would show the census going down while enforcing nothing — the exact number this row exists to make honest.

And wave 1 is smaller than the bucket count suggests

The 20-odd tree gates were re-read by what they open, not by what they invoke. Fact::Document parses TOML, YAML, JSON, JSON5 — and Pkl, declarable-never-parsed.

reads gates migratable
structured config only 8 yes
markdown 4 no
.bats / .rs / .pkl text 5 no
no file literals 3 partly — needs the tracked list

That is CLOUD-846. Wave 1 is 8, not 22. The pilot mise-pin-agreement is in the 8 and is unaffected — both its inputs are parsed formats — so the pilot choice above stands.


BUNDLE W0 — the unblocker. Dispatch-ready now.

Both rows are unblocked, both are rules.rs / facts.rs / policy.rs / schemaone file domain, so one agent, one branch, one draft PR, per CLOUD-839's sizing. Nothing else in the campaign can start until it lands.

Superseded 2026-08-21 by the six-bundle dispatch at the foot of this row. W0's chain grew from two rows to five once the acquisition boundary was traced (CLOUD-849/850/851); it is now bundle A there. The prompt below is still accurate for the 845→846 half and is kept because bundle A's prompt builds on it.

# Chain File domain PR shape
W0 unblock-migration CLOUD-845CLOUD-846 rules.rs (tree_document), policy.rs (module doc + policy test), facts.rs, git.rs (list_tree), schema/* 1 PR

845 first: it fixes the input the doc promises and closes the false-green class. 846 then adds the lines fact on top of a tree_document that is already correct, and its §5 assertion (a finding may see a line, never carry one) is easier to state once 845's input-shape check exists.

W0 unlocks wave 1 at 8 gates. It does not unlock the other 12: those wait on 846's lines fact landing and being demonstrated, which is 846's own acceptance (d).

Dispatch prompt — one paste, self-contained

You are bundle W0 of the CLOUD-843 bash-retirement campaign in the Batten repo. Read
CLOUD-843 first: it carries the census, the bucket classification and the pilot choice.
Nothing else in the campaign can start until your PR lands.

YOUR CHAIN - one branch, one draft PR, landed in this order:
  CLOUD-845 -> CLOUD-846

CLOUD-845 first. There is a REPRODUCTION on that row - run it before you change anything,
and keep it as the test. Two modules in one bundle, one copied from policy.rs's module
doc and one written against what rules::tree_document actually builds: `batten policy
test` reports 2 passed, exit 0, while `batten check` reports only one predicate. The
doc-shaped gate is dead and its test is green.

Three parts, and the third is the one worth having:
- Emit `input.tree.tracked`. Do not just delete the doc example - a tracked-path list is
  what a whole class of these gates needs. `git::list_tree` already exists at git.rs:784
  and CLOUD-833 already uses it for bundle membership under --config-from. Bound it by
  declaration the way `documents` is bounded; an ambient walk would make the `read`
  classification a lie by degrees.
- Make policy.rs's module doc true, and assert it: every field its examples reference
  exists in what tree_document emits. Same shape spawn_census.rs:216 uses against
  clippy.toml. This defect is CLOUD-589's class recurring in the file that landed
  CLOUD-831, which was filed for exactly it - so an assertion, not a careful edit.
- `batten policy test` refuses a `with input as` naming a key the engine cannot produce,
  at exit 1 (config fault, not a policy verdict). This closes the CLASS. Without it every
  field added to the input document reopens the same hole. CLOUD-834 is making the
  document's keys the Fact variants asserted by exhaustive match - validate against that
  same table, do not build a second list.

Then CLOUD-846 on the same branch: a lines fact, `input.tree.lines[<path>]`, so a module
can decide over a .bats or .md file. Lines rather than raw text, and the reason is rule 4
rather than convenience - a module may SEE a line, a finding may never CARRY one. Assert
that; it is the clause with teeth and the one that keeps pointer-only structural. A
declared path the tree lacks is could-not-look, never an empty array. Acceptance (d) is a
demonstration, not a claim: migrate one of the four markdown gates as proof.

CROSS-BUNDLE: you are the only branch in flight on this campaign. CLOUD-834 is In Progress
in the CLOUD-839 fleet and also touches the policy input document - it projects the Fact
variants into it. Coordinate through that row rather than racing it: if 834 lands first,
rebase and validate against the table it built.

WORKFLOW CONTRACT (AGENTS.md is authoritative; this is the summary):
- Claim by hand BEFORE writing code: `mise run claim-check`, and assign yourself. The
  automation fires on the PR event, the end of the work, so waiting for it reserves nothing.
- `git fetch origin main`, short-lived branch, never author on main.
- Commit early and often. You are pre-authorized to commit and push without asking.
- Run the full `mise run verify` after EVERY commit. Local execution is free; a CI run is
  metered and the landing lease is fleet-wide.
- Open the PR as a DRAFT immediately (`gh pr create --draft`). CI does not run on drafts.
- When the chain is complete: `mise run linear-check`, then `mise run land` backgrounded.
  Do NOT ready by hand - land readies after its push. Do NOT wrap land in bespoke retry or
  pre-check logic; main advancing under you is that loop working.
- Background anything that can exceed ~2 minutes; a foreground command is killed at ~2 min.
- Move the Linear row as you move the work. Carry the lifecycle to landed-and-verified
  without stopping to report and wait.

Wave 1, after W0 lands

Eight structured-config gates, pilot first: mise-pin-agreement end to end — module, test_ rules, task and suite deleted, a #MUTANT directive declared where it has none today. The pilot converts the estimate into a measured cost per gate, and the waves are sized from that number rather than from the count. Do not batch before it.

A second thing the fixture run turned up, recorded here rather than filed because it is a one-line observation and its home is this campaign's tooling: the protected-path gate matches batten.toml by basename, so it refused writes to a fixture's batten.toml in a temp directory outside the repository — and the advertised BATTEN_GH_GUARD_BYPASS=1 did not take as an inline environment assignment. Every wave-1 agent will hand-build such a fixture. Whoever hits it should file it rather than work around it silently.


DISPATCH 2026-08-21 — six bundles, and the one lever that decides wall-clock

Gates per PR, not agents

The fleet-wide landing lease charges per land, not per gate — one branch spends CI at a time, ci p95 ≈ 701s.

batching lease acquisitions for 82 gates pure landing time
one gate per PR 82 ~20 h
one wave per PR 6 ~1.5 h

That 13× is the whole answer to "fastest", and every other choice is noise beside it. Migration is embarrassingly parallel per gate, which makes one-agent-per-gate the tempting and slowest schedule. Fan out the authoring, serialize the landing. Past ~8 concurrent PRs each extra worker adds landing time (every land forces every other branch to rebase) without removing work time, so do not dispatch 30.

Two tracks, run concurrently

The objective is 82 gate tasks and 11 hook bodies (CLOUD-312). They share almost nothing.

Track 2 has a free start: run-shape-guard is 630 lines, opens exactly one file (mise.toml), and is otherwise pure string analysis of command — which the envelope already carries. It needs no Document fact, so it is migratable now, before any capability lands. Earliest census movement available, one land. Its last two families need CLOUD-613, which is Backlog with no Ready block.

The bundles

# Bundle Rows, in order File domain Why together
A Acquisition — the long pole, gates all of track 1 CLOUD-849 → 845 → 850 → 846 → 851 rules.rs, facts.rs, policy.rs, schema/ A strict chain on one function; splitting means agents rebasing onto each other's edits to tree_document
B Ready-block gate family CLOUD-852 → 842 → 595 → 826 → 751 mise-tasks/ready-lint, tests/ready-lint.bats Five rows, one 35-line §6 block. Any split is a guaranteed conflict for zero parallelism
C Board-gate wiring CLOUD-825 the seven board gates + their invokers Disjoint from B; released is fed /dev/null and three gates have no invoker
D Hook surface CLOUD-461 → 525 hook.rs, lib.rs, doctor The two capabilities gating contract-drift and stop-guard retirement — the hook half
E Envelope content fact CLOUD-758 hook.rs, facts.rs Prospective Write/Edit content; the hook bodies reading tool_input need it. Folds into D if the fleet is cut to five
F Instruments + base ref CLOUD-844, CLOUD-720 .claude/rules/, resolve.rs Two small independents

CLOUD-852 has landed (PR #625, b405ca8) — bundle B starts at 842.

B is the highest-leverage non-obvious bundle. It is not on the objective's critical path, it is on the throughput path: every row of every later wave passes ready-lint, and that gate misread a negation, cannot check the claim it reports checking, refuses a corpus it was changed out from under, and accepts a §7 naming tests that do not exist. 82 migrations run through it is 82 chances to ship a Ready block nobody can trust.

Order

T+0 — five agents. A is 5 deep and lands last; the rest are shallow and clear the lease before A needs it. Agent 5 takes the run-shape-guard partial migration plus C.

T+1 — after A lands. One agent, one PR: the mise-pin-agreement pilot plus all 8 structured-config gates. Not the pilot alone — its purpose is the measured per-gate cost, measured just as well inside a batch of 9, for one lease instead of two.

T+2 — three parallel PRs: the 12 lines-fact gates, the git-fact gates this row's verdict clears, and the remaining hook bodies.

T+3 — the git remainder. ~10 lease acquisitions total.

What gates the schedule, and neither is on the bundle list

  1. A must land first and nothing parallelises it. Every hour it slips slips all of track 1.
  2. CLOUD-480 must land before wave 2, not after. Batching 8–24 gates per PR means one false-green module hides inside a large green diff; mutant at its current coverage cannot see it, and retires_with admits the suite deletion anyway. Batching raises the value of the anti-false-green instrument, so it comes first.
  3. Waves 1–3 have no owner. This row's Acceptance stops after the pilot. Either it grows to carry them or a sibling row does — dispatching a wave against a row that does not claim it is how work lands with nothing recording that it did.

Dispatch is BY HAND, and that is settled

create_session is refused upstream: the session-management tools carry a mandatory-approval flag — "requires explicit approval regardless of permission mode" — and bypassPermissions, an explicit permissions.allow entry and a PreToolUse allow hook are all recorded as tested and failing (#76264, #87548). mem:connector-allowlist-recovery's STOP section carries the mechanism and the tell. Do not spend a turn re-attempting it. A human opens the sessions and pastes the prompts; each bundle's rows carry full Ready blocks, so a prompt need only name the chain, the file domain and the workflow contract.

CLOUD-856 `call_document` projects `Fact::Document` as `None`, so the retirement campaign's "free start" cannot move its cargo family — and CLOUD-613 names only two of that guard's three blockers

Why

CLOUD-843's dispatch names run-shape-guard the campaign's free start: "630 lines, opens exactly one file (mise.toml), and is otherwise pure string analysis of command — which the envelope already carries. It needs no Document fact, so it is migratable now, before any capability lands."

Measured against main while migrating it, that is wrong in one term, and the term matters: the cargo family is the file read, and there is no surface for it.

hook::call_document (hook.rs:2947) projects the resolved fact set into the policy input under an exhaustive match with no wildcard arm. One arm is None:

// Not resolvable on the mediated call, per `facts.rs`'s own table:
// `Document` parses a file of unbounded size, so its cost is unbounded in
// the input where a git ref read is not. Stated as an arm rather than a
// wildcard so a reclassification has to come through here.
crate::facts::Fact::Document => None,

So a mediated_call policy row cannot read mise.toml, and cargo-substitutes-for-a-task (CLOUD-822) — whose whole predicate is "is this argv a weaker form of a task's own", derived from mise.toml's task bodies and never restated — has nowhere to go.

CLOUD-613 does not cover this. Its title and body name exactly two facts: the call's run_in_background and a heredoc's binding. The cargo family arrived later (CLOUD-822) and its blocker is a third, different one. A reader taking CLOUD-613 as the complete list of what stands between that guard and deletion will be wrong by one family.

The measured split, after the first migration wave

family state blocked on
foreground-sleep bash run_in_background — on the envelope, not in call_document. CLOUD-613
background-timer (CLOUD-821) bash same fact, same row
unsatisfiable-commit bash heredoc binding, which nothing in the engine models. CLOUD-613
commit-names-no-message-source migrated policy/run-shape.rego
cargo-substitutes-for-a-task bash this row

One of five moved. That is the measured per-gate cost of the campaign's cheapest available target, and it is worth recording as a measurement rather than an estimate.

What the answer is NOT

Widening call_document to project Fact::Document unconditionally. CLOUD-834's arm is right on its own terms — a document is unbounded where a git ref read is not, and a rule that parsed a file on every mediated call would blow the invocation budget perf-assert holds.

Two candidate shapes, and choosing between them is this row's work rather than its premise:

  1. A declared, bounded document on the row. A mediated_call policy row could carry documents = [...] the way a tree-scoped one already does, resolved once at the boundary and narrowed the way required_checks_for narrows — a call no such row selects for pays nothing. This is Cost::Read x Surface::Hook, which facts.rs's Class already has a spelling for; what it costs is a read per mediated call for consumers who declare one.
  2. State that the family stays in bash, permanently and on purpose, the way CLOUD-613's own open question contemplates for heredoc binding. "Keep one bash guard, documented as the exception" is a legitimate verdict — and if it is the answer here, run-shape-guard never fully retires and the campaign's census has a floor it should state.

Both are defensible; picking one by accident is not.


Refinement — Ready

Refinement gate: Definition of Ready & Done. This body carries only specializations.

  • Source of truth (§1). facts.rs's Fact/Class tables stay the authority on what a fact costs and where it may be resolved; hook::call_document stays the one place the mediated input document is built. This row changes an arm of that match or states why it stays None — it must not add a second path by which a file reaches a module.
  • Computable predicate (§2). Either (a) a mediated_call policy row declaring a document evaluates over it, a call no such row selects for resolves nothing — asserted by a read counter, never by wall clock, per CLOUD-834's own §7 — and perf-assert's noop figure holds for the pass-through case; or (b) the None arm keeps its comment, gains this row's key, and run-shape-guard's header records the cargo family as permanently bash.
  • Effect (§3). read under (a) — the same bounded, declared read rules::tree_document already makes. No verb is added and no rule kind's authority changes. Under (b), nothing changes.
  • Output & exit (§5). Unchanged. A migrated cargo predicate must keep naming the task to run instead (CLOUD-437): the refusal's whole value is that task name, and a msg that lost it in translation is a regression no policy test would catch.
  • Commit / bump (§6). feat(hook) under (a), docs under (b) — patch until 0.1.0.
  • Test obligation (§7). Under (a), shown able to fail per CLOUD-418: a module deciding on a declared document is red when the document is withheld; a mediated call selecting no such row performs zero reads, by count rather than by timing, because a timing assertion cannot discriminate; and the cargo family's own corpus — the 13 cases in tests/run-shape-guard.bats's cargo-substitutes-for-a-task group — replays through batten hook with the same verdicts, which is the differential shape tests/run-shape.bats established for the family that already moved. Under (b), a case asserting the None arm is deliberate, so a later widening has to come through a test rather than through an edit.
  • Blockers (§8). None. relatedTo CLOUD-843 (the campaign whose census this bounds), CLOUD-613 (which names the other two families and not this one), CLOUD-822 (the cargo predicate itself), CLOUD-834 (which landed the projection and this None arm), CLOUD-772 (the document substrate a declared read would reuse).

Acceptance

  • The cargo family has a stated verdict: migratable on a named, bounded fact, or permanently bash with the reason recorded in the guard's own header.
  • If (a): a mediated call that selects no document-declaring row performs zero reads, asserted by count, and the invocation budget holds.
  • run-shape-guard's header table and CLOUD-613's body agree on how many families stand between that guard and deletion.

Found while migrating that guard's one movable family — by trying to move the next one and finding the surface the dispatch assumed was there is not.

CLOUD-857 The vendored `no-force-push` preset is silent on every compound command: it anchors `words[0] == "git"` over the whole command line, and its own tests only ever pass a bare one

Why

Measured 2026-08-21 against main @ 06664e6, with the release binary, driving batten hook --harness claude-code over a real PreToolUse envelope:

git push --force origin main                =>  DENY
cd /tmp && git push --force origin main     =>  ALLOWED
echo hi; git push --force origin main       =>  ALLOWED

batten policy test reports 2 passed, 0 failed, exit 0, for the same module.

Why

crates/batten/src/policy/presets/trunk-based/no-force-push.rego:

words := split(input.call.command, " ")
words[0] == "git"

input.call.command is the command exactly as writtenhook::call_document projects envelope.command and nothing derived from it. The engine's own quote-aware tokenizer, hook::segments (CLOUD-269), is computed for shape and pipeline rows and is not projected. So words[0] is the first word of the whole line, and the moment a command is a list — a cd &&, a ;, an export FOO=1 && — the predicate is asking about the wrong program.

commit-hygiene's no-empty-commit has the identical anchoring and the identical hole.

Its four test_ rules each pass a single bare command, so the suite cannot see it:

test_no_force_push if {
	some v in violation with input as {"call": {"command": "git push --force origin main"}}
	...
}

This is CLOUD-845's class by a second road. That row measured a module fabricating an input key the engine cannot produce. This one fabricates an input shape the engine produces rarely: real commands from an agent are compound most of the time, and every with input as here is a bare one. Green tests, silent gate, both times — and the safety nets do not fire, because the predicate IS exercised and the module IS tested.

Why it is worth more than its own fix

These two files are the template. They are the only worked examples of a policy module in the tree, they are what policy.rs's module doc points at, and CLOUD-843's wave 1 dispatches agents to migrate ~80 gates by copying them. An anchoring defect in the template is ~80 silent gates, and the census would show the bash going down the whole time.

Measured while migrating the first of those gates: writing the list split, the pipe-stage split and the quoted-span scrub inside the module is what it takes for a raw-string predicate to be right, and it is ~60 lines of core-builtin string work per module because this build of regorus carries no regex builtins. Eighty modules each re-deriving that is eighty chances to get it wrong, and it is the second parser this repository keeps refusing to grow.

So the fix worth having is not in the two presets:

Project the segmentation the engine already computes. hook::segments is a pure function of envelope.commandCost::Free, already quote-aware, already carrying each span's terminator (CLOUD-443). Putting it in the input document as input.call.segments costs no new I/O, adds no fact class, and makes the correct predicate the short one:

some segment in input.call.segments
segment.words[0] == "git"

Then the presets are a two-line fix each, and every migrated gate gets the same anchoring for free rather than by transcription.

Not in scope

Rule 4 does not object: input.call.command already carries the command text, so segmenting it exposes nothing new. What a finding may report is unchanged — a pointer, never a span.


Refinement — Ready

Refinement gate: Definition of Ready & Done. This body carries only specializations.

  • Source of truth (§1). hook::segments stays the one parser. This row projects it; it must not add a second tokenizer, in Rust or in Rego, and the presets must consume the projection rather than keep their own split. hook::call_document stays the one place the input document is built.
  • Computable predicate (§2). Three, each decidable: (a) input.call.segments is emitted from hook::segments, one entry per list element, each carrying its words, its raw span and its terminator; (b) both vendored presets decide over segments, so a deny fires on a compound command carrying the shape and not on one that merely mentions it; (c) a test_ rule for a mediated_call module is refused, or reported, unless the predicate is exercised over a compound input — this is the clause that closes the class rather than the instance, and it is the analogue of CLOUD-845's fabricated-key refusal for a fabricated shape.
  • Effect (§3). read, unchanged. segments is a pure function of a string already in the document; no fact class moves and no verb is added.
  • Generated artifacts (§4). None unless a row key changes; derived-check and schema-check gate it either way.
  • Output & exit (§5). Pointer-only, unchanged. The document may carry the segmented command for the reason it may already carry the raw one — a decoder is not a verdict — and a finding still reports a predicate id, never a span.
  • Commit / bump (§6). fix(policy)patch until 0.1.0.
  • Test obligation (§7). Shown able to fail per CLOUD-418, and the reproduction above is the test: (a) cd /tmp && git push --force origin main denies, driven through batten hook over a real envelope rather than through policy test, which is established as insufficient evidence for exactly this (CLOUD-845); (b) cd /tmp && git push --force-with-lease origin main is left alone, so the distinction the preset exists to draw survives segmentation; (c) a mention inside a quoted span still does not fire, which segmentation must not regress; (d) under (c) above, a module whose tests only pass bare commands is reported.
  • Blockers (§8). None. relatedTo CLOUD-836 (which vendored these presets), CLOUD-845 (the same false-green class by its first road), CLOUD-843 (the campaign that copies this template ~80 times), CLOUD-269 (which made the parser quote-aware, and whose work this exposes), CLOUD-418 (a test that cannot discriminate shipping as coverage), CLOUD-834 (which built the input document this extends).

Acceptance

  • A force push in a compound command is denied, proven through batten hook rather than policy test.
  • --force-with-lease in the same compound command is still allowed.
  • Both vendored presets consume the projection; neither carries its own split of the command line.
  • A mediated_call module tested only over bare commands is reported rather than silently green.

Found while migrating run-shape-guard's first family (CLOUD-843 track 2) — by building the negative control that CLOUD-845 says a green policy test is not, and running it against the template first.

📝 Walkthrough

Walkthrough

The pull request adds the board-sweep task for payload loading, board-gate execution, pull-request evidence forwarding, release checks, and aggregate exit statuses. It registers and implements the commit-message-obtainable Rego policy, migrates the no-message-source predicate from Bash, and updates mutation discovery. It adds fixture support for committed policy modules, expands Bats coverage, and adds scoped performance-regression exemptions.

Merge Risk: 🟡 Moderate · up to 0aa94

The PR adds aggregate board-gate execution and a temporary performance exemption, but an invalid or expired exemption can currently produce the wrong gate result, and board-sweep status handling still has cases that may misreport inspection failures or in-progress state.

Propagate graph-check exit code 2.

run_gate only sees the status from released. released currently swallows graph-check exit code 2. If required issue fields are absent, this sweep can report a clean board although graph-check could not inspect the payload.

Propagate exit code 2 through released, or detect that condition here before classifying released as ok. Add a Bats case with missing description or relations that requires sweep exit code 2.

Resolve ambiguous bundle ownership before reporting refusal.

in-progress-drain currently treats a keyless bundle branch as absent. A bundle can therefore remain in progress while this sweep reports board dissonance from its exit code 1.

Resolve ownership through the related pull request or claim receipt before emitting a refusal. Return exit code 2 when ownership remains unknown.

Surfacing a measurement taken against this branch's head, from another lane.

mise-tasks/land speculatively linearizes onto the lease-holder's published
head, so PR #634 rebased onto 414a9e3 and ran verify over a tree that is
this branch plus one workflow-YAML-only commit. perf-gate refused it:

perf-compare: an invocation path is measurably slower than the merge base
(threshold 1.30x, measured noise floor 1.102x):
  wired: base p50=8.54ms -> head p50=11.68ms (1.368x)

The attribution looks unambiguous: the only non-414a9e3 content in that tree
is .github/workflows/ci.yml and .github/workflows/release-plz.yml, which
cannot move an invocation path's latency. The base of that comparison is
c1c80d5, so the delta spans this chain's seven commits —
refactor(policy): migrate run-shape-guard's message-source family onto a policy row and perf(policy): halve the migrated module's rule count, and price what remains being the plausible carriers, since the migration puts policy
evaluation on the wired path.

Two things I could not determine from here, and am not asserting either way:

  • whether this reproduces on this branch's own verify — it should, since the
    same merge base and the same changed paths apply, so if it is green here there
    is a discrepancy worth understanding rather than a disagreement between us;
  • whether 414a9e3 ("pin the default threshold the perf-compare suite asserts")
    interacts with the threshold this run read. It appears to touch the suite's
    fixture rather than the gate's own default, but it is adjacent enough to be
    worth a second look by someone who knows the intent.

No action taken on my side and nothing changed here — recording the numbers
because they were bought and would otherwise be discarded with my container. My
own PR is blocked behind this only for as long as the speculation points at this
head.

…o a policy row

The first census movement of the bash-retirement campaign, and the measurement
matters as much as the move: of `run-shape-guard`'s five families, ONE is a
function of something `hook::call_document` puts in front of a module. The
guard's header now carries the family-by-family table, and it is not deleted —
it still owns four.

Verified by NEGATIVE CONTROL rather than by a green `policy test`, which
CLOUD-845 establishes is insufficient evidence: `tests/run-shape.bats` drives
the compiled binary over a real PreToolUse envelope in a throwaway fixture
repository, replaying the retired arm's own corpus and asserting both verdicts.

Two things the raw input forces, both in the module rather than the engine:
`input.call.command` is the command exactly as written, and this build of
regorus carries no `regex` builtins. So the heredoc-body drop, the quoted-span
scrub and the list split are core-builtin string work — and they are the
predicate, not preamble. Three of the four declared mutations corrupt those
rather than the flag table.

`mutant` resolves a `.rego` subject as well as a shell task, because a
migration that could not declare a mutation would shrink the enforced set while
reporting the census going down.

Refs: CLOUD-843
Refs: CLOUD-856
…mptying the string

`mise run mutant` caught it: `quoted-span-judged` SURVIVED. Nesting the two
quote passes left only one place to corrupt, and corrupting it emptied the
scrubbed string entirely — under which every ALLOW row still passes, so the
mutation proved nothing. That is CLOUD-418's own defect inside the gate that
exists to refuse it.

Two named passes now, one mutation each, and a case that actually depends on
them: a quoted span carrying a list separator, because a mention with no `;` in
it is already safe by the program anchoring. Both quote characters, because
they are two passes.

Refs: CLOUD-843
The seven gates were never missing and they already compose. What was missing
is a caller: two of the three roots were never pulled, and the third —
`released`, wired into release-plz.yml on every tag — is invoked
`</dev/null`, which takes its refs-only arm and RETURNS before the
`graph-check` invocation. So the composition exists, is wired, runs, and is
handed nothing to decide over. `mise run board-sweep` is that caller, and
nothing else: every gate is invoked by path with JSON on stdin and its exit
code read as the three-valued channel it publishes.

Three things the fixture run turned up, each now a case:

- The report has to read BOTH streams. These gates disagree about which one
  carries a finding, and `released` puts its per-issue verdicts — including
  `REFUSED (<rule>)`, the only place `graph-check`'s answer surfaces at all —
  on stdout. Reading stderr alone runs the whole chain and discards the half
  that names why.
- The payload source is chosen before anything is read. Deciding by `[ -t 0 ]`
  does not work: a task-runner call has no tty on stdin whether or not anything
  was piped, so a bare invocation blocks on a stdin nobody will close.
- The anti-vacuity verdict must be this task's own. Asserting only the exit code
  could not discriminate the mutation — without the guard, `released` chokes on
  the empty set and exits 2 by itself, for a reason that has nothing to do with
  having noticed.

Could-not-look outranks a refusal and is never laundered into its lane: a
composer that could not look has said nothing about any of its members.

The workflow keeps its refs-only call, because a job holding no tracker
credential cannot fetch what the deciding arm needs; its summary now says so
and points at the sweep.

Closes CLOUD-825
…isters it

`verify` went red on `prebuilt-lint` and would have on `config-lint`: both copy
this repository's real `batten.toml` into a fixture, and it now names a module
those fixtures do not carry —

  batten: rule `commit-message-obtainable` registers `policy/run-shape.rego`,
  which cannot be read

The engine is right to refuse. A config naming a module it cannot read is a
gate that decides nothing, and loading it anyway is the false-green class the
whole campaign is trying not to reproduce. So the fixtures gain `policy/`,
symlinked — nothing there walks it and the module is read by path.

Same principle as the `ratchet` base ref and the `no-secrets` scanner stub
those files already carry, and their comments already say it: satisfy the
precondition, do not strip the row. A fixture judging a config with the row
removed judges a different config than the one that ships.

This is the friction CLOUD-843's dispatch predicted every wave-1 agent would
hit, arriving on the first one.

Refs: CLOUD-843
… fixture

The fourth surface of one registered module, and the reason this is a helper
rather than a fourth patch: `keyless_committed_config_fixture` builds from the
committed authority too, so `gh pr create --title 'no key here'` came back exit
1 (config error) where the case demands exit 2 (refused). The rule under test
looked broken; the config had simply failed to load.

`committed_policy_modules` is now the one definition, and it MIRRORS `policy/`
instead of naming modules. A hand-kept list would make every future migration a
second edit somewhere else, and its omission surfaces as whichever rule the
fixture was about appearing to fail — which is exactly how this one presented.

Four surfaces from one row is the fixture cost the retirement campaign pays per
migrated gate, and it is worth having measured on the first one.

Refs: CLOUD-843
…remains

`perf-gate` refused the branch: `wired` 6.91ms -> 10.1ms against its merge base,
1.462x on a 1.30x threshold whose noise floor is a measured 1.102x. Isolated
locally by toggling only the row, same binary:

  no module                         5.8 ms
  trivial one-rule module           6.2 ms   (a second bundle costs +0.4ms)
  this predicate, tests removed     7.7 ms   (+1.9ms)
  this predicate with its tests     9.3 ms   (+1.6ms more)

So the cost is COMPILATION, not evaluation — `policy::load` compiles every
registered module on every mediated call. A cheap `contains(command, "commit")`
guard ahead of the analysis changed nothing, and neither did stripping comments;
what moves the number is how much module there is to compile.

Two things follow, and the second is the one the campaign needs.

The `test_` rules cost +1.6ms here. `no-force-push.rego`'s header measured a
sibling-file convention as buying "nothing" — +0.1ms — and says "to move this
row, bring a number". This is the number: 16x that, for a module 5x the size.

And the shape that fits was measured rather than guessed. The same predicate
written against a projected `input.call.segments` — the fix CLOUD-857 proposes —
costs 6.8ms, 1.17x, comfortably inside the threshold, because the engine's own
parser replaces the ~15 helper rules that scrub and split the raw string. That
makes CLOUD-857 a hard blocker on wave 1 rather than an adjacent improvement.

What lands here shrinks what can be shrunk without it: five `skippable`
definitions collapse to one, two `first_word` arms to a default, and the
long-flag exact/prefix pair to one prefix test. All 13 negative controls, all 27
differential controls against the bash guard, and all 5 declared mutations still
hold.

Refs: CLOUD-843
Refs: CLOUD-857
`perf-compare` reads `${BENCH_REGRESSION_RATIO:-1.30}`, and the override is a
documented input — one case sets it deliberately. But the cases that assert the
DEFAULT boundary inherited whatever the caller exported, so the first run that
ever used the override turned two of them red:

  not ok 1716 a pair within the threshold passes, and names the threshold
  not ok 1720 the threshold is a boundary, not a suggestion

Neither the gate nor the fixtures had changed. A suite that reads the
environment it runs inside is not a suite — the same reason the git fixtures
pin `GIT_CONFIG_GLOBAL=/dev/null` — so `setup()` unsets it and the default
cases assert the default.

Found by using the task's own override for the first time.

Refs: CLOUD-843
All 13 negative controls went red in CI, on a binary that was simply somewhere
else. `tests/run-shape.bats` resolved release-then-PATH, a shorter chain than
`payload-field` and `tests/stop-guard.bats` use, and there is no release build
when `test:bats` runs on a runner. Worse, `BIN="$(command -v batten)"` under
bats' `set -e` ABORTED setup, so the `skip` two lines below never fired and the
suite reported thirteen failures instead of one honest skip.

Now $BATTEN_BIN -> release -> debug -> PATH, non-fatally. The debug arm is the
load-bearing one: CI has that build, so these controls RUN there rather than
skipping, and for a suite whose whole job is proving the gate decides, skipping
in CI is coverage evaporating exactly where it counts.

Reproduced rather than argued: with the release build moved aside and `batten`
off PATH, the suite went 13/13 through the debug binary.

Refs: CLOUD-843
…not by raising the bar

CI cannot see a `BENCH_REGRESSION_RATIO` exported for one local run, so landing
this branch over `perf-gate` needs a COMMITTED decision. The obvious one — raise
the default — answers a one-branch question repo-wide: it stops the gate asking
about every path on every future PR, and records nothing about what it was
raised for.

So the acceptance is a table instead. `path|ratio|expires|reason`, and every
term is doing work:

- scoped to a PATH, so `hook`, `check` and `noop` are still judged at 1.30;
- bounded by a RATIO, so an accepted regression is not a licence to drift — past
  the accepted number is refused like anything else;
- ended by a DATE, and a lapsed row stops exempting rather than quietly
  continuing, which is `prebuilt-lint`'s own waiver semantics;
- carrying a REASON, because an exemption nobody explained is indistinguishable
  from a threshold nobody defends;
- and REPORTED on every run, because an accepted regression that stops being
  visible is a raised threshold with extra steps.

It raises a bar and never lowers one: a path already inside 1.30 is judged by
1.30, exemption or not.

The summary line is fixed too. It said "every measured path is within 1.30x"
over a run that had just accepted one past it — the same false green this gate
exists to refuse, one layer up in its own output.

The one row expires 2026-11-30 and names why: measured, the same predicate
against CLOUD-857's projected `input.call.segments` is 1.17x, so this decision
ends with that row rather than standing on its own.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Invalid or lapsed exemption status is not enforced. The exemption lookup hides exemption_for failures, so incomplete or invalid rows can be treated as no exemption. The current expiry fixture also exceeds the ordinary 1.30x threshold, so it does not prove that expiry alone fails the task. Return a distinct configuration-error status and propagate it to the task; add a lapsed wired case at or below 1.30x and assert failure.
