Bundle A: the landing floor — 674, 827, 904, 903, 727 in one land

[wenzowski]

Bundle A of CLOUD-926 — the landing floor. Five rows, one land.

This branch was taken over rather than reopened: it carried PR #651's original
CLOUD-871 lap-cap change, and was stale across a rename and across a shallow
clone. It stood 1 commit past f3eb5cd while main had moved 57 commits
on, and git merge-base origin/main HEAD returned nothing — the histories read
as unrelated. Recovery was fetch --unshallow, reset to origin/main, and
re-applying the two hunks by hand onto mise-tasks/land.sh (the rename target)
rather than merging.

What lands

row	what it fixes
CLOUD-674	closing-key-check held both halves of "did this body close every key the branch served" and never subtracted them. A bundle closing 3 of 8 stranded 5, and the passing line announced the board would move.
CLOUD-827	Nothing priced a prose-only branch, so two sentences of doc comment bought a full required matrix against a trunk landing every ~16 minutes.
CLOUD-904	The lap cap asserted a diagnosis its own refunds had already removed, and the two exhaustion paths gave imperatives opposite to their costs — the free one said stop, the expensive one said go.
CLOUD-903	Work landed by a Refs:-only PR was permanently undrainable: both arms of landed-check's disjunction turn on a claim, and neither can ever become true.
CLOUD-727	A verify failure on a speculatively linearized tree was reported as the author's, sending them after a borrowed base's defect — once, into land's own suite.

The order was dependency, not taste

CLOUD-674 is first because its position is worth more than its content: every
later bundle in CLOUD-926 strands its tail until it lands. CLOUD-827 is second
because bundle D is almost entirely prose and currently buys a full matrix for it.

This PR is the first body its own new gate judged, and it refused it

The subtraction fired on this branch, naming CLOUD-926 and CLOUD-871 as served but
not closed. Both are legitimately not-to-be-closed — the dispatch record, and a row
whose disposition is to fold into CLOUD-843. The only escape the spec offered was a
bare DO-NOT-CLOSE, which exempts the whole body, so the gate would have
shipped passing its own PR for the one reason a bundle must never pass: nobody
checked.

So the marker is now per-key where it names one (CLOUD-527, already in 674's
§8), and global only when it names nothing. That is the last commit here, and it is
the dogfooding rather than an afterthought.

Not landing, and why

CLOUD-859 was claimed and is left In Progress with a full diagnosis on the row.
Its §2 specifies a rego predicate over reviews / latestReviews / reviewThreads,
and none of those fields can reach rego: facts::Sourced stores exactly
{command, seen_at, rows}, because rows_in reduces the buffer to a count at the
boundary and no byte is stored ("Rule 4, structural rather than careful"). §5's
pointer-only thread ids are unemittable for the same reason. A workable substitute
exists — put the selection in the declared command and let rows == 0 carry the
verdict — but it is a different predicate, so re-specifying §2 is the row author's
call. A second, unmeasured blocker is recorded there too: rows_in recognises two
buffer shapes and a shell tool's is explicitly not one of them, so a
gh api graphql fact may mint no record at all.

CLOUD-465 and CLOUD-464 are assigned; claim-check refuses both assigned.
The refusal is written on each row and no takeover was taken — that flag answers
"the competitor is this branch", and here it is not.

Verification

mise run verify green; tests/land.bats 145/145 (the suite's stopping-condition
count assertion moved 31 → 33, which is how a new stop cannot be added silently);
tests/closing-key-check.bats 32/32; tests/landed-check.bats 31/31; the full
test:bats tier 2708/2708; ci-local-parity green; batten-check clean; every
declared mutation across the touched gates caught.

Two defects found in the tooling while establishing that, both recorded rather than
left in chat: mise run mutant was silently skipping declared mutations and
reporting them caught (done <<<"$rows" put the rows on stdin and bats ate
them — fixed here, recorded on CLOUD-944, and it invalidates that row's
"149 declarations, every one caught" baseline), and CLOUD-941 plans to build a
verdict that already exists as inert-mutation.

Closes CLOUD-674
Closes CLOUD-827
Closes CLOUD-904
Closes CLOUD-903
Closes CLOUD-727

DO-NOT-CLOSE CLOUD-926 — the dispatch record this bundle rides under.
DO-NOT-CLOSE CLOUD-871 — its disposition is to fold into CLOUD-843, not to ship a gate.

[linear-code]

CLOUD-871 Gate remedy text is unaudited prose that steers the agent, and tonight one sentence steered it into the one unrecoverable action

Why

Every gate in this repository ships a remedy sentence, and nothing judges that sentence. The exit code is gated, tested and mutation-checked; the words next to it are unreviewed prose that the agent reads and acts on. That makes the text an interface, and it is the only part of the gate surface with no predicate over it.

THE ENGINE ALREADY ENFORCES THIS, AND THAT IS THE ARGUMENT. crates/batten/src/findings.rs:729-736 refuses to store a finding carrying no remedy:

Ingest refuses an un-settleable finding rather than storing one nothing can close. rules::validate already refuses the rule that would produce it — and pointer-only, never the finding's content. A finding a caller cannot act on is not storable.

Two layers hold it, and 18 batten.toml rows carry no_fix_reason to satisfy it. So this row is not proposing a new opinion about wording. It is the observation that three message surfaces sit outside an invariant this codebase already holds, and that all four instances below are on those surfaces:

• the 555 ::error:: strings in mise-tasks/, which are free prose;
• batten hook deny text, which names a fixed bypass regardless of the rule (CLOUD-437);
• the stop-hook question text, whose remedy has no durable destination (CLOUD-326).

That reframes the work from audit the prose to extend a structural requirement to the surfaces that lack it — which is implementable, and which the engine has already shown the shape of.

The instance, measured 2026-08-21. mise-tasks/land's lap cap prints:

land: still not linear after 2 laps, each of which bought a CI matrix;
`main` is moving faster than a lap takes. Look before lapping again.

An agent read that as an instruction to stop lapping until the fleet quietened, and stopped. That is the single worst available action: mise-tasks/land's own header (lines 4-12) states that lapping is the catch-up mechanism — "each lap rebases onto a little more landed work, so conflicts arrive one small resolvable increment at a time instead of accumulating until a branch cannot land at all." Stopping ages the branch while the target moves, which is exactly the terminal state that sentence exists to prevent.

The message is not wrong. It is ambiguous in the unsafe direction: it supplies a rationale for stopping, then an imperative whose most natural reading is stop. The cheapest compliant behaviour was the catastrophic one.

This is not one bad sentence. Two other gate surfaces steered the same agent the same session:

• completion.unlanded resolves to "Land it, or say what blocks it." The second arm is satisfied by free text, so three consecutive wrong or stale block claims cost no exit code (recorded on CLOUD-732).
• CLOUD-437 records that every batten hook deny advertises BATTEN_GH_GUARD_BYPASS, including denies with nothing to do with gh — a remedy naming the wrong escape.
• CLOUD-680 records an override ask presented as a menu of routes rather than the binary decision it is.

Four instances, four surfaces, one missing predicate.

Where the harmonization actually stands, since this text lives on the surfaces being consolidated. Counted on main 2026-08-22: .claude/settings.json registers 21 hook commands across 8 events — 8 batten-rust, 13 shell. CLOUD-713 built the sensor for the PreToolUse slice and is Done; nothing counts the other seven events. Every shell guard retired under CLOUD-312 takes its unaudited prose with it, so the text surface shrinks as the binary absorbs it — which is the argument for putting the predicate on the binary's message table rather than on 13 shell scripts that are leaving.

Refinement — Ready (make the remedy sentence a checked artifact, not prose)

• Source of truth (§1). The refusal and remedy strings themselves, in crates/batten and the surviving mise-tasks/* gates. No second list: the predicate reads the strings where they are emitted.
• Mechanism as a computable predicate (§2). Mirror the engine's own requirement rather than inventing a prose heuristic: a terminal refusal must carry a remedy that names a runnable object, or an explicit marker declaring that none exists — the shell analogue of no_fix_reason. Fix the regression or take the decision again with a new date is an honest remedy with no command behind it and must stay expressible; what must not stay expressible is a refusal that names neither.
• Scoped to the refusal, not to every emission (§2). The predicate attaches to the message accompanying the exit, not to each ::error:: line. Measured on main 2026-08-22, mise-tasks/ carries 555 such lines and only 79 name anything in backticks — so the naive reading fires on 476 of them, 86%, which CLOUD-751's own criterion rules unshippable. Sampling shows that number conflates four populations and only the third is the defect: multi-line headers ending in a colon whose detail follows; diagnostics that are not remedies at all (path '$id' was measured on head but not on base. No verdict.); genuine prose remedies with no runnable object; and remedies naming an environment knob rather than a command. A predicate that cannot tell those apart is measuring punctuation.
• Deliberately not in scope (§2). Readability, tone and length. The or say what blocks it escape hatch itself — CLOUD-732 owns that. The override-ask shape — CLOUD-680. Registration and retirement — CLOUD-777 and CLOUD-312.
• Effect (§3). read. The gate reads committed strings and resolves to an exit code.
• Output and exit (§5). Pointer-only: the emitting path:line and which clause failed. Never the message body, which would put the prose under review in the output of the gate that judges prose.
• Commit / bump (§6). feat(gate) → patch.
• Test obligation (§7). Mutation-checked per CLOUD-418. The discriminating cases are the four real instances above, used as fixtures: the lap-cap sentence must fail, the or say what blocks it arm must fail, a remedy naming a command must pass. And per CLOUD-751, the gate ships with a measured firing rate over the committed corpus — if it fires on most existing messages the clause is too strict, and that number decides the threshold rather than taste.
• Blockers (§8). None. relatedTo CLOUD-777 (the registration invariant this text rides on), CLOUD-312 (each retirement removes unaudited prose), CLOUD-751 (the firing-rate obligation this must satisfy), CLOUD-680 and CLOUD-437 (two more instances of the same missing predicate), CLOUD-732 (the escape-hatch arm).

Acceptance

• The four recorded instances are shown red before the fix and green after, each as a fixture.
• The safe-default rule is an authoring obligation, not a gate clause, and it is the one the lap-cap instance needs: where a remedy admits both continuing and stopping, the imperative names the continuing action, because for a queue that ages stopping is unrecoverable and continuing is merely slow. Nothing decides from committed text that a remedy ends a loop, so a §2 clause claiming to would be a model verdict wearing a predicate's clothes. It lands as a documented rule with land's lap cap fixed as its worked instance.
• A new gate whose remedy asks for a judgement with no runnable object is refused before it can land.
• The gate reports a measured firing rate over the committed message corpus, and that number is on the row.
• The count of unaudited message surfaces falls as CLOUD-312 retires shell guards, and something reports it for all 8 hook events rather than only PreToolUse.

CLOUD-904 The lap cap reports a diagnosis its own refunds refute, and the two exhaustion paths give opposite imperatives — the spent one says go, the unspent one says stop

Why

mise-tasks/land.sh's lap cap prints a diagnosis that the same file's accounting makes impossible, and its remedy is the opposite of the remedy on the sibling exhaustion path. Both are readable from committed text; neither is about wording taste.

The cap cannot mean what it says. charge_wait (land.sh:383) decrements lap on every path that bought no CI, and says so:

Both must refund the lap — a busy fleet would otherwise exhaust LAND_MAX_LAPS on waiting alone and give up without ever having attempted

Three paths refund: the lease was held by someone else (land.sh:1466-1473), the lease was won over a main that had moved, and the fast-forward bot gave no readable answer (land.sh:391-399). So a lap counts only when it actually spent a CI matrix. Reaching LAND_MAX_LAPS therefore means this branch spent max_laps matrices and none of them landed — it does not mean main outran a lap, because the laps main outran were refunded before they could count.

The message says the second thing:

still not linear after $max_laps laps, each of which bought a CI matrix;
`main` is moving faster than a lap takes. Look before lapping again.

The first clause is right (each counted lap did buy a matrix). The second is the inference the refunds already removed — and it is the same diagnosis land.sh:391-396 records as measured-wrong:

charging it to the lap budget would let a rate-limited bot exhaust the budget that exists to catch "main moves faster than a lap takes" — and would report that diagnosis, which is what CLOUD-413 measured being wrong twice over across 24 laps

CLOUD-413's fix was to stop charging the lap. The sentence that reported the wrong diagnosis was left standing.

The two exhaustion paths contradict each other. CLOUD-399 made them distinguishable by exit code; their remedies were never reconciled.

exit	path	CI spent	imperative today
LAND_EXIT_FLEET_SATURATED (land.sh:388)	never won the lease	none	"The fleet is saturated: wait, or land later."
LAND_EXIT_RUNAWAY (land.sh:1177)	spent max_laps matrices, none landed	max_laps matrices	"Look before lapping again."

The path that cost nothing tells the caller to stop. The path that cost two matrices is ambiguous, and button-inc/batten#651 proposes resolving that ambiguity to "RUN THIS AGAIN" — unconditionally, which re-arms the only brake on that spend and buys max_laps more matrices with nothing about the branch or main changed. Whichever posture is correct, "free ⇒ stop, expensive ⇒ go" is not it.

Found reviewing PR #651, which fixes the ambiguity in the message and leaves both underlying defects in place. That PR is CLOUD-871's worked instance and is the right place to land the corrected text; this row owns the two facts that decide what the corrected text should say. Without it, #651 is a wording change on top of a wrong diagnosis.

Searched before filing (issue-search-check, 25 rows): CLOUD-385 is the nearest and is a different claim — a lap taking longer than the mean commit gap, which is the condition the refunds were later added to absorb. CLOUD-413 removed the charge and is Done. Nothing owns either the stale diagnosis or the mismatched pair.

Refinement — Ready

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

• Source of truth (§1). mise-tasks/land.sh — charge_wait, the three refund sites, and the two die_with calls. The accounting is the authority on what each exit means; the message is downstream of it and must be derived from it, never restated beside it. No second table of "what the exits mean".
• Mechanism as a computable predicate (§2). Two clauses, both decidable over committed text and neither a judgement about wording:
  1. The runaway message must not assert the refunded inference. The literal moving faster than a lap takes may appear in the file's explanatory comments (land.sh:394 earns it — it is describing the bug) but not inside the die_with for LAND_EXIT_RUNAWAY. That is a string over one emission site, not a heuristic over the class.
  2. The two exhaustion remedies must not both be terminal-with-no-continuation. Expressed as a bats case pair rather than a text predicate: the fleet-saturated exit names waiting, the runaway exit names a continuing action, and each names the cost the caller is deciding about. This is the discriminating assertion — today both cases exist (tests/land.bats:1077, :1108) and neither reads the other's remedy.
• Deliberately not in scope (§2). The general "remedy names a runnable object" predicate — CLOUD-871 owns it and has already measured it unshippable as a text scanner (103 of 420, fires on 75%). Changing LAND_MAX_LAPS's value or the refund policy itself: the accounting is correct, only its report is wrong. LAND_LOCK_MAX_WAITS and the lease.
• Effect (§3). read for the predicate. The message change is a mise-tasks/ edit with no new verb.
• Output and exit (§5). Exit codes are untouched — LAND_EXIT_RUNAWAY=5 and LAND_EXIT_FLEET_SATURATED keep their CLOUD-399 meanings. This changes what each says, never what it returns.
• Commit / bump (§6). fix(land) → patch.
• Test obligation (§7). Mutation-checked per CLOUD-418, and the mutation must break the property, not a literal — the mutation on PR Bundle A: the landing floor — 674, 827, 904, 903, 727 in one land #651 (s/RUN THIS AGAIN/look/ against an assertion hardcoding RUN THIS AGAIN) is caught by identity and discriminates nothing. Discriminating mutations here: restore the refuted diagnosis clause into the runaway die_with; swap the runaway remedy to the fleet-saturated one. Both must turn a named case red.
• Blockers (§8). None. relatedTo CLOUD-871 (owns the remedy-text class and the worked instance; this row decides that instance's content), CLOUD-413 (removed the charge and left the sentence), CLOUD-399 (made the two exits distinguishable by code and not by remedy), CLOUD-843 (land.sh is a forge-bucket gate — this is a bash edit today because the surface it would migrate onto does not exist yet).

Acceptance

• The runaway refusal states what its own accounting supports — max_laps matrices spent and unlanded — and does not assert that main outran a lap.
• The two exhaustion refusals are shown, as a pair of cases reading both messages, to give imperatives consistent with their costs: the unspent path may say wait; the spent path must name a continuing action and the spend the caller is re-committing.
• Both mutations above turn a named case red, and mise run mutant reports them caught.
• PR Bundle A: the landing floor — 674, 827, 904, 903, 727 in one land #651's message is superseded rather than merged as-is: the corrected text lands there, derived from this row's two facts.

Found reviewing PR #651 on 2026-08-22, by reading charge_wait against the message it is supposed to explain.

CLOUD-674 `closing-key-check` never checks that the body closes every key the branch served, so a bundle PR strands its tail and the log reads as a clean pass

Why

CLOUD-661 sanctions the one-PR-per-bundle shape and records, as its second cost, that the branch "must be KEYLESS, and nothing checks that it is." Its Ready block then declares "Computable predicate (§2). None, and that is the honest answer rather than a gap."

That declaration is too strong. A predicate exists, its inputs are already in tree, and the call site already exists.

Measured on main at b2f8992 (HEAD == origin/main, so this is shipped behaviour, not a branch artifact). Three bodies piped to mise run closing-key-check:

Body	Output	Exit
Closes ×3 — CLOUD-593, CLOUD-655, CLOUD-661	closes CLOUD-593 CLOUD-655 CLOUD-661 — the merge will move the board	0
names CLOUD-655/657/658/661 in prose, Closes CLOUD-593 only	closes CLOUD-593 — the merge will move the board	0
DO-NOT-CLOSE CLOUD-388	DO-NOT-CLOSE — this PR declines to complete its issue	0

Row 2 is the defect. Four issues strand, and the passing message announces that the board will move. A reader of that log has no way to tell it from row 1.

The comparison set already exists inside the same script. closing-key-check computes named — every key the body mentions — and uses it only to decide whether the gate has anything to judge. It never compares named to closing. So the gate holds both halves of the answer and does not subtract them.

It cannot simply require named ⊆ closing, and the file already says why. A body cites related issues, prior measurements and superseded work as evidence; named is deliberately over-broad, which is the whole reason claimed-keys (CLOUD-338) exists as a narrower authority. Requiring every mentioned key to be closed would refuse almost every correct PR this repo writes.

And it cannot use claimed-keys either — that comparison is circular. claimed-keys' source 1 is a closing keyword in the body, so for a PR whose branch is keyless the claimed set is derived from the closing set and agrees with it by construction. The gate would pass on exactly the bodies it needs to refuse.

The non-circular set is the commits. Every commit already records which issue it served as the first key of its Refs: trailer, with the remaining keys as citations. On claude/dependency-automation-bundle:

1f6e87e  Refs: CLOUD-593, …
67c2928  Refs: CLOUD-593, CLOUD-654, CLOUD-102
b6592c7  Refs: CLOUD-661, CLOUD-502, CLOUD-367, CLOUD-596, CLOUD-344, CLOUD-527
d3c04f4  Refs: CLOUD-658, CLOUD-593, CLOUD-657, CLOUD-344, CLOUD-105
8b07f31  Refs: CLOUD-657, CLOUD-596, CLOUD-105, CLOUD-656
daab6e8  Refs: CLOUD-655, CLOUD-596, CLOUD-105, CLOUD-418
093d0e3  Refs: CLOUD-593, CLOUD-344, CLOUD-661, CLOUD-103

First keys = {593, 655, 657, 658, 661}. PR #491's body closes exactly those five. A clean positive control, and the rule it satisfies:

the set of first-Refs: keys across the branch's commits ⊆ the set of keys the body closes, unless DO-NOT-CLOSE.

The honest caveat, stated rather than discovered later. The first-key convention is practised but undocumented — grep -n "Refs" .claude/rules/commits.md returns nothing. So the gate ships with the convention written down beside it, or it enforces an unwritten rule and the next author breaks it without warning. That is scope, not a blocker.

Why this is worth a gate rather than a line of prose. It is the shape non-negotiable rule 2 exists for, and CLOUD-661 measured the same shape one step earlier: the convention was satisfied and the outcome still wrong. A stranded issue is invisible when it happens — nothing turns red, the PR merges, and N−1 issues sit In Progress with their work already on main. landed-check catches that state afterwards, on a later sweep, by which time the board has been wrong for however long. This refuses it at the readying moment, which is where closing-key-check already stands.

Refinement — Ready

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

• Source of truth (§1). mise-tasks/closing-key-check owns the verdict and is extended rather than joined by a second gate — a second authority over "will this merge move the board" is the defect that file's own header warns about. .claude/rules/commits.md gains the Refs: first-key convention, which is the input this depends on.
• Computable predicate (§2). first-Refs-keys(branch) \ closing-keys(body) = ∅, or the body carries DO-NOT-CLOSE. A command and an exit code over the commit log and the body, no network, no model verdict — the same stdin-plus-git shape claimed-keys and deferral-check already use.
• Effect (§3). No command-surface change. land already pipes the body to closing-key-check beside deferral-check (mise-tasks/land:1186,1201), so the branch is read from the clone that is already checked out — no extra fetch, no extra lap.
• Output & exit (§5). Pointer-only (non-negotiable 4): the stranded keys and the verdict, never a line of the body. Exit 1 for "this PR will strand keys", exit 2 for unreadable stdin — matching the file's existing table so callers compose unchanged.
• Commit / bump (§6). feat(gate) for the check plus docs(rules) for the convention → patch (below 0.1.0, where every releasing type collapses to a patch). It ships no library surface, but a feat commit still cuts a release.
• Test obligation (§7). Bats coverage with both controls drawn from real state: positive — PR Dependency automation: Renovate for mise.toml, then github-actions and cargo change hands #491's body against its branch's seven commits, exit 0; negative — the same branch with a body closing only CLOUD-593, exit 1 naming the four stranded keys. Plus DO-NOT-CLOSE passing, a single-ticket PR unaffected, and a commit whose Refs: trailer is absent entirely (no claim ⇒ do not judge, the reading claimed-keys already takes). A #MUTANT row for the subtraction itself, since a gate that always returns the empty difference is a rubber stamp every other row still passes.
• Blockers (§8). blockedBy CLOUD-661 — this corrects a §2 declaration CLOUD-661 is landing right now in PR Dependency automation: Renovate for mise.toml, then github-actions and cargo change hands #491, and plan-fleet step 3's rule is that two tickets over one file domain are sequenced, never raced. relatedTo CLOUD-527 (the DO-NOT-CLOSE marker the predicate must honour), CLOUD-338 (claimed-keys — the authority this deliberately does not reuse, with the circularity recorded above so the next reader does not re-propose it), CLOUD-344 (all-or-nothing: this makes the cost visible rather than removing it).

Acceptance

• A body closing a strict subset of the keys its branch's commits served exits 1 and names the stranded keys.
• PR Dependency automation: Renovate for mise.toml, then github-actions and cargo change hands #491's real body and branch exit 0 — the positive control is a landed artifact, not a fixture invented for the test.
• DO-NOT-CLOSE still passes, and a branch whose commits carry no Refs: trailer is not judged.
• The verdict is one authority: closing-key-check is extended, no second gate is added.
• .claude/rules/commits.md states the first-key convention the predicate reads.
• Output names keys and a verdict only — no line of the PR body appears.
• The declared mutation is caught, and mise run mutant, mise run verify and the hk gate are green.

CLOUD-827 Nothing prices a prose-only branch, so two sentences of doc comment can buy a full CI matrix against a trunk that lands every 16 minutes

Why

Measured 2026-08-21, on this repository, by doing it: a branch whose entire diff was two rewritten sentences of //! doc comment in crates/batten/src/git.rs went through verify and was on its way to gh pr create + land — a full required matrix (ci, cross, commit-lint, zizmor, darwin-link, semver, perf, windows, final) against a trunk landing every ~16 minutes. It was stopped by a human saying "don't you dare waste CI minutes for comments", which is the wrong mechanism: this repository's whole posture is that a rule ships with a runnable gate, and the economics here are the most gate-shaped thing in the workflow.

Nothing in land's pre-ready gate set asks what the diff is worth. verify asks whether it is correct, linear-check whether it is landable, ready-guard whether both were proved — and then a matrix is spent on a change no required check can say anything about that verify did not already say locally.

The economics are already written down elsewhere, which is what makes this an omission rather than a new opinion. AGENTS.md: "Local execution — bash, a build, the whole test suite — costs nothing... A CI run costs real minutes." ci.yml's own header: "CI minutes cost money; an agent's local execution does not. So CI runs as rarely as correctness allows." That file then lists the two economies it implements — drafts run nothing, and main is not a trigger. A third economy is missing: a change CI cannot have an opinion about should ride the next change that it can.

What makes it worth a gate rather than a habit. The agent had the rule (it is in AGENTS.md), had just spent four laps of the landing loop on disk exhaustion and lease races, and still queued the matrix — because every gate it consulted said yes. A rule that is only prose is feedforward, and this is the failure mode CLOUD-514 and CLOUD-323 were each built to close on a different axis.

The nuance that must survive into the predicate

A comment is not inert in this repository, and a naive "comments are free" rule would be wrong. Several gates read comments as their subject:

• every_stays_shelled_out_claim_names_its_price (git.rs) scans the module doc for citations.
• no_gix_gap_primitive_survives scans all of src/ for retired vocabulary.
• spec-ref-check resolves CLOUD-<n> §N citations in tracked files.
• rules-drift holds restated defaults against their mechanisms.

So a comment change can change a verdict — and that is precisely why the economy holds rather than fails: every one of those gates runs in verify, locally, for free. If a comment change breaks one, the author learns before a runner is spent. CI is confirming what was already proved; on a prose-only diff it confirms nothing that could differ.

Shape

A gate in land's pre-ready set, beside deferral-check, filed-here-check and closing-key-check — the three that already refuse a lap on grounds other than correctness, and whose refusal text names remedies rather than a flag.

The predicate is over git diff origin/main...HEAD: a branch is prose-only when every added and removed line in every changed file is a comment line for that file's language (//, //!, #, or the whole file being *.md), and no file under tests/ changed. That last conjunct is what makes the common good case pass: a change that adds or edits a test is not prose-only, which is why PR #604 — a doc rewrite plus the gate that enforces it — would be admitted, while the follow-up carrying only the two sentences would not.

The refusal names the same remedy the human named: put it on the row that owns it, and let the next change to those files carry it. Recorded override for when the prose IS the deliverable and cannot wait — the BATTEN_FILED_HERE_OVERLAP idiom, which records what it overrode rather than switching the rule off.

Acceptance

• A branch whose diff is comment lines only, with no test change, does not reach gh pr ready without an override that is recorded.
• A branch that changes a comment and a test, or a comment and any code line, is untouched — this prices batching, never doc work.
• The refusal names where the content should go instead, and the override records which branch used it.
• The gate is in verify's path and in land's pre-ready set, so it costs no runner to enforce.

Refinement — Ready (2026-08-21)

• Source of truth (§1). A new mise-tasks/ gate, named and wired beside deferral-check and filed-here-check in land's pre-ready sequence — the existing home for a refusal that is about cost rather than correctness. No new config surface: the predicate reads the diff and nothing else, so there is nothing for a consumer to tune, and no second list of what counts as prose.
• Predicate (§2). Over git diff --unified=0 origin/main...HEAD: exit non-zero when every +/- line is a comment for its file's language and no path under tests/ is changed; exit 0 otherwise, including when the diff is empty or cannot be computed. Comment syntax is per-extension and deliberately narrow — .rs (//, //!, ///), shell and mise-tasks/ (#), .md in full — with an unrecognised extension counting as not a comment, so an unknown file type admits the branch rather than blocking it.
• Effect (§3). read — a diff read and an exit code; no verb, no surface, no new process kind, nothing written.
• Output / exit (§5). Pointer-only and the standard table: the refusal names the changed paths and a count, never a line of the diff, and exits 2 as a policy verdict. No verb gains or loses a code.
• Commit / bump (§6). feat → patch (below 0.1.0 every type collapses to a patch).
• Test obligation (§7). A bats suite in the shape of tests/filed-here-check.bats: a comment-only diff refuses; a comment-plus-code diff passes; a comment-plus-test diff passes (the PR fix(git): name what the remaining spawns cost, and gate that the doc keeps saying it #604 shape); a .md-only diff refuses; an unrecognised extension passes; an empty diff passes; the override records the branch it admitted; the refusal names no diff content. Shown able to fail by reverting the predicate to a constant pass.
• Blockers (§8). None.

Found 2026-08-21 while landing CLOUD-320's module-doc fix, when the gate that should have refused the follow-up was a human instead.

CLOUD-903 Work landed by a `Refs:`-only PR is permanently undrainable: both arms of `landed-check`'s disjunction are false forever, and CLOUD-270 has sat that way since 2026-08-09

Why

landed-check decides landedness by a disjunction: a claiming commit on main (via claimed-keys), or the caller's evidence naming a merged PR closing the id. Both arms turn on a claim rather than a mention — which is correct, and is CLOUD-804's fix.

The consequence nobody priced: a key whose work landed through a Refs:-only PR satisfies neither arm, and never will. No later event can create a closing key for an already-merged PR, and no later commit will claim an id whose work is already on main. The row is undrainable by gate, permanently, and the gate reports it as not landed — which is true of the evidence and false of the tree.

The measured instance

CLOUD-270, In Progress today, work on main since 2026-08-09.

grant in main	.claude/settings.json:193 → mcp__serena__*; mcp-allow-check green
PR #198	merged 2026-08-09T18:04:50Z, body ends Refs: CLOUD-270, branch claude/groom-cloud-35-zxgre4
PR #201	merged 2026-08-09T18:27:33Z, body ends Refs: CLOUD-270, same branch
closing keys for CLOUD-270	none, in either

Run today with an honest (empty) --merged-prs file, landed-check answers no In Progress issue has commits on main. That verdict is correct against its inputs and wrong about the world.

The branch named CLOUD-35, so the tracker's automation moved CLOUD-35 — which was Canceled — to Done, and left CLOUD-270 where it was. PR #201 exists only because someone noticed and wrote the memory correcting it. CLOUD-270 then reached Done by hand on 2026-08-11, and was knocked back to In Progress on 2026-08-21 at 23:26:21Z, three seconds after PR #639 opened citing it in prose (CLOUD-705's class). So the row has been wrong in both directions, and the gate that exists to arbitrate cannot see it.

Why this is not already filed

• CLOUD-804 created this by tightening the predicate off bare grep. That tightening is right; this is its unpriced residue, and reverting it is not the answer.
• CLOUD-735 is the same symptom — both exits unreachable — with a different cause: a dispatch record opens no PR and lands no commit. CLOUD-270 opened two PRs and landed commits; the keying is what failed.
• CLOUD-469 built the sweep. A sweep cannot help a row the predicate structurally cannot see.
• CLOUD-674 is the mirror on the write side: closing-key-check not requiring a closing key for every key the branch served is how a row ends up in this state. This row is what happens afterwards.

Scope — MEASURED 2026-08-23, acceptance leg 1

Against main at 1180 commits and every merged pull request (merged-pr-keys, 302 closing-key rows over 290 distinct keys; claimed-keys --closing-only over main's full log, 44 keys — a subset of the PR set, so the union is 290):

column	rows	undrainable by BOTH derived arms	...and mentioned on main	...never mentioned
In Progress	37	37	5	32
In Review	51	7	7	0

The answer is 5, not 30 — and that is what makes a per-row asserted arm defensible where a derived one would not be. The five: CLOUD-480, CLOUD-605, CLOUD-631, CLOUD-869, CLOUD-883. The seven In Review: CLOUD-180, CLOUD-352, CLOUD-398, CLOUD-585, CLOUD-673, CLOUD-813, CLOUD-843.

That all 37 In Progress rows are undrainable is expected rather than alarming — most are this fleet's own live claims, correctly In Progress, and 32 of them are not mentioned on main at all. The population this row is about is the 5 that ARE mentioned with no claim anywhere.

Method note, because it nearly produced a wrong number. The first run passed main's log to claimed-keys through --log in argv and got 0 claimed keys, which would have made arm 1 look structurally dead. That is the Argument list too long hazard landed-check and merged-pr-keys both document — the log is over 1 MB. Through stdin the same call returns 44. A measurement tool that fails silently in the zero direction is exactly the shape this row is about, so it is recorded rather than quietly corrected.

CLOUD-270 reproduces, and its column has now been wrong in THREE directions

Still undrainable, still mentioned on main, work on main since 2026-08-09 through PRs #198 and #201 — neither closes it. Its history since this row was filed:

Done (2026-08-11, by hand) → In Progress (2026-08-21 23:26:21Z, three seconds after PR #639 merely CITED it) → Backlog (2026-08-22 20:54Z).

So landed work now sits in not yet Ready. The row is no longer only undrainable; it is drifting, and each move is someone guessing because no gate can answer. That is the argument for a recorded route over a hand-move, and it postdates this row's own filing.

Scope, honestly (superseded by the measurement above)

Unknown how many rows are in this state. The population is "In Progress or older, whose only merged PRs cite rather than close" — computable from the board plus PR bodies, and worth measuring before choosing a remedy, because a one-off hand-move for CLOUD-270 is right if the answer is 1 and wrong if it is 30.

Refinement — Ready

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

• Source of truth (§1). GitHub for the PR bodies and main's commits, the tracker for the column. claimed-keys stays the one authority on claim-versus-mention — this row must not add a second reading of that distinction (CLOUD-378 is what applying it unevenly costs).
• Computable predicate (§2). First a measurement, then a remedy chosen against it; shipping the remedy first is what makes this row a guess. The measurement is a pure function of the board plus merged-PR bodies: for every non-terminal row, does any merged PR close it, and is any claiming commit on main? The remedy candidates, not to be pre-empted here: a third evidence arm the caller can supply for retro-keyed work (with the forgery risk stated, since the caller assembles it); or an explicit terminal state for "landed, key never claimed" so the row leaves the column with its history intact rather than by a silent hand-move.
• Effect (§3). read for the measurement. A remedy touching landed-check stays read; nothing under crates/ unless a new arm needs the engine.
• Generated artifacts (§4). None.
• Output & exit (§5). Untouched — pointer-only, CLOUD-<n> and a PR number, never body text.
• Commit / bump (§6). ci → no bump, unless the remedy reaches crates/batten/src.
• Test obligation (§7). Shown able to fail (CLOUD-418), and the discriminating case is the one this row is about: a row whose merged PR closes it drains, a row whose merged PR only cites it does not, and the two are reported differently — a predicate that collapses them is CLOUD-804 undone.
• Blockers (§8). None.

Acceptance

1. The population is measured and stated as a number, not an impression.
2. A row landed by a Refs:-only PR has a route out of In Progress that is not an unrecorded hand-move.
3. Whatever route is chosen, a mention still never counts as a landing — CLOUD-804's distinction survives intact, shown by a test.

Found auditing the Serena ticket set: CLOUD-270 was reported as "wrongly In Progress, run landed-check", the gate was run, and it refuted the remedy rather than confirming it. The refutation is the finding.

---

Disposition — the remedy chosen against the number

Remedy candidate 1 (a third caller-supplied evidence arm) is implemented; candidate 2 (a new terminal state) is not, and at n=5 a board-model change is not warranted.

landed-check gains --landed-by <file>, <CLOUD-id><TAB><ref> lines the caller ASSERTS carry the work. Three properties keep it honest, and each is a bats case:

• Per-id and explicit. A mention still never counts, anywhere — CLOUD-804's distinction survives intact (acceptance leg 3, with a case asserting a citing commit plus an unrelated assertion still exits 0).
• Reported separately. A row drained this way prints asserted by --landed-by: <ref>, so a reader can tell the caller's word from the gate's evidence rather than trusting the union. Its anti-vacuity twin asserts a DERIVED landing is not labelled asserted.
• Optional, absent-is-empty. Unlike --merged-prs, whose absence is exit 2 because it would silently halve a disjunction that almost always answers. Absent here only ever ADDS to the landed set, so it cannot manufacture a false green. An unreadable file is still exit 2.

The forgery risk is real and is the price: the caller assembles the file, so a wrong line lands a row that never landed. That is stated in the file's header rather than left implicit — it is what buys reach over rows no derivation can see.

Two #MUTANT rows: dropping the arm returns the population to permanently undrainable; deleting the asserted label collapses the caller's word into evidence. mise run mutant reports 4 declared across landed-check, every one caught; the suite is 31 cases green.

Not done here, and deliberately: the five rows are not moved. This lands the mechanism; using it is a board sweep with a human deciding each assertion, which is the dispatcher's Done-pass work and not something to bulk-apply from a bundle. CLOUD-270 in particular now sits in Backlog and needs a decision about which column is true, not an assertion that it landed.

CLOUD-727 A verify failure on a speculatively linearized tree is reported as the author's, so land sends them after a borrowed base's defect

Measured 2026-08-19, on a two-commit branch touching only .serena/memories/*.

land speculatively linearized while waiting for the lease, and said so:

land: speculatively linearized onto claude/groom-cloud-491-qv83e7@9575991 — the main that is about to exist

verify then failed, and the refusal read:

land: verify failed on 592f0a3 (exit 1). Reproduce and fix locally; CI is not where you discover this.

The two findings were Cargo.lock sbom-ntia-conformance and mise-tasks/claim-race-check claim-not-raced. Neither file is touched by either commit on the branch. Rebasing off the speculative base with git rebase --onto origin/main 9575991 and re-running was green first try, so the failure belonged entirely to the borrowed base.

Second measurement, 2026-08-22 — a controlled pair, and the borrowed base was landing concurrently

Same shape, three days later, on a two-commit branch again touching only .serena/memories/*.

land failed verify and reported it as this branch's. The failing case was **tests/land.bats:1310** — a body that names its issue but never closes it stops before review is asked for`. It failed because a DIFFERENT stop fired first and masked the one under test:

not ok 1310 a body that names its issue but never closes it stops before review is asked for
#   `[[ "$output" == *"names its issue but never closes it"* ]]' failed
# Last output:
# ::error:: land: #150 defers a decision with no ticket. ...

⚠️ RETRACTED, SAME DAY — this instance does NOT belong to this issue

The two-arm result below was written as "the failure belonged entirely to the borrowed base, confirmed rather than argued." That conclusion was wrong, and the error is worth keeping visible because it is CLOUD-732's shape: a causal claim from two data points that do not separate the variable.

A third arm settles it. After the borrowed commits LANDED on main, the same case was re-run against a tree containing them:

tree	how it ran	result
speculative (2 own + 4 borrowed)	inside full mise run verify (hk, bats -j 4)	not ok 1310
own 2 commits on origin/main alone	single filtered bats run	ok 1
main at f3eb5cd, carrying the same 4 borrowed commits	single filtered bats run	ok 1

Arms 1 and 3 are effectively the same CONTENT and disagree. So content is not the variable — how it ran is. Arm 1 alone went through the full parallel suite.

The same branch then landed through land on lap 1 with every required check green, over a base already containing those four commits, which is independent confirmation that the base was never broken.

Correct reading: tests/land.bats:1310 fails under the full parallel verify and passes in isolation. That is a test-isolation defect and belongs with CLOUD-466 (single-instance in-gate failures under the parallel backend, unreproduced) and CLOUD-412's class — not here. Filed separately rather than left on this row.

What this instance still legitimately supports for THIS issue is narrower and survives: land reported a failure on a speculatively linearized tree with no mention that the tree under test was not the author's, and the reasoning cost of working out whose it was ran to several steps and one wrong answer — mine. The message defect is real; this instance is evidence of its cost, not of a borrowed defect.

The original two-arm claim, kept for the record

tree	result
speculative (2 own commits + 4 borrowed)	not ok 1310
own 2 commits on origin/main alone	ok 1

"So the failure belonged entirely to the borrowed base, confirmed rather than argued." — wrong, per the third arm above.

Two details this instance adds:

1. The borrowed base was another agent's PR landing at the same time — the attribution-check retirement, four commits (refactor(gate): retire attribution-check's prose half into a forbid row and three others). Its author had it in flight; the speculation pulled it under an unrelated branch mid-flight. That is the live risk the section below names, reached without anyone doing anything wrong.
2. The masked failure was in land's own suite. An author following the message would have gone looking for a defect in the landing loop — the very mechanism reporting the failure — which is the most expensive possible wrong place to send them.

Recovery was git reset --hard origin/<own branch>: the speculation is local, and nothing borrowed had been pushed. Worth stating in the fix's message, since "rebase --onto" is not the only answer and the cheaper one is available when the remote still holds the clean branch.

Why this is the message's defect and not the mechanism's

CLOUD-369's design is sound and this issue does not reopen it. The safety invariant holds — settle_speculation runs at the top of every lap and a losing bet resets rather than pushes, so no borrowed commit can reach main. The speculation is also genuinely free while waiting, exactly as the header argues.

What is missing is attribution on the failure path. land knows it speculated: it holds spec_base, and it printed that base a few lines earlier. On a verify failure it nonetheless emits the unconditional message above, whose two sentences are both wrong in this case — "reproduce and fix locally" points at a defect the author did not write, and "CI is not where you discover this" implies discovery is overdue when the tree under test is not the one the author will ever push.

The cost is not the wasted verify; that is the speculation's accepted price. The cost is the reasoning needed afterwards to work out whose failure it was, and the live risk that an author takes the message at its word and starts repairing a sibling's branch through their own.

The shape of the fix

land already has the fact. On a verify failure with spec_base set, name it: the tree under test carries <base>'s unlanded commits, the failure may be theirs, and git rebase --onto origin/main <base> is the one command that answers whose it is. The existing message stays verbatim for the ordinary case, where it is correct.

Refinement — Ready

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

• Source of truth (§1). mise-tasks/land, the verify-failure branch alone. No change to settle_speculation, to the bet's record, or to any exit code — the mechanism is correct and only its report is not.
• Computable predicate (§2). With spec_base set and verify failing, the emitted refusal names the speculative base; with spec_base unset it is byte-identical to today's. Both are assertions over land's stderr, which tests/land.bats already drives.
• Effect (§3). Unchanged. No new command surface, no new network call, nothing added to the lap.
• Output & exit (§5). Pointer-only and the exit code is unchanged — this adds a coordinate (the base ref and sha land already printed) and never a diff or a finding body. The 0/1/2/3 table does not move.
• Commit / bump (§6). One commit, fix(land) → patch, which is what every type produces below 0.1.0. It will nonetheless cut no release, for a reason independent of the type: release-plz versions the package, and mise-tasks/ is outside crates/, so the run leaves it already up to date. In Review is therefore the truthful column until a later release sweeps the commit up.
• Test obligation (§7). tests/land.bats, two cases in opposite directions: a failing verify under a speculative base names that base, and a failing verify with no speculation emits exactly the message it emits today. The second is what stops the fix widening a message that is already right in the common case.
• Blockers (§8). None.

2026-08-22, later — four laps lost to speculation in one session, and the fourth breaks a surface the unwind does not restore

The instances above are about the failure MESSAGE. This one adds a cost the row does not currently name: speculation can invalidate state outside the working tree, and settle_speculation's reset does not reach it.

The instance

Lap 4, on a one-commit branch touching only .serena/memories/*. land speculatively linearized onto claude/codemod-bash-rego-transform-lp49pn, and the branch went from 1 commit ahead of main to 16. verify then failed in doctor, after 10 seconds:

::error:: no executable pre-commit hook at .git/hooks/pre-commit — commits in this
         clone bypass the gate. Do: run .claude/hooks/session-start.sh, or symlink
         it to .claude/hooks/git-hook.sh
::error:: no executable commit-msg hook at .git/hooks/commit-msg

Nothing was wrong with the clone. The borrowed commits are the .sh rename campaign, and they rename .claude/hooks/git-hook → git-hook.sh. The session's .git/hooks/pre-commit and commit-msg are symlinks minted at session start against the name that exists on main:

.git/hooks/pre-commit  -> /home/user/batten/.claude/hooks/git-hook      (session start, matches main)
.claude/hooks/          git-hook.sh                                      (speculative tree, renamed)

So the speculative checkout silently dangled both symlinks, and doctor — correctly — refused a clone whose commits would bypass the gate.

Why this is not just another misattribution

.git/hooks/* is outside the working tree. Every other instance on this row is a tree-content failure that git rebase --onto origin/main <base> fully reverses. This one happens to reverse too, because the symlink resolves again once the rename is gone — but that is luck, not design: the reset restores refs and the tree, and has no notion of what a symlink into .claude/ pointed at. A borrowed commit that MOVED a hook target permanently, or that a lap unwound in the other order, would leave the clone gateless with nothing in the unwind to notice.

It is also the cheapest possible false alarm to act on wrongly: the refusal names a remedy (run .claude/hooks/session-start.sh), and running it against a speculative tree would re-point the clone's hooks at a file that is about to vanish when the speculation unwinds.

The tally this session

lap	what stopped it	whose
1	disk exhaustion, surfaced as a compile error	environment (CLOUD-861)
2	disk exhaustion, then still not linear after 2 laps	environment, then misattributed to main moving
3	land.bats:1310 + 5 run-shape.bats cases, on a 6-commit speculative base	borrowed / unresolved (CLOUD-466)
4	doctor, dangling git-hook symlinks, on a 15-commit speculative base	borrowed, this entry

Four laps, zero caused by the one-file change under test. Each was reported to the author as their branch's failure. That is the cost this row exists to price, and the sample is now large enough to state it as a rate rather than an anecdote: in this session, every verify failure land attributed to the author was in fact environmental or borrowed.

What this adds to the fix

The shape proposed above — name spec_base on a verify failure — covers this instance too, and one line more would have saved the diagnosis outright: when the speculative base renames or deletes a path the clone links to, say so. That is decidable (git diff --name-status origin/main..$spec_base over the hook targets) and needs no judgement. Offered as an observation about scope, not as a new requirement on this row.

⚠️ CORRECTION to the lap-4 entry above — that instance is NOT this row's, and it inverts

The entry above filed lap 4 as "borrowed, this entry" and priced it as a cost of speculation. Wrong, and the next lap proved it within the hour.

Lap 5 ran with no speculation at all (grep -c 'speculativ' → 0, branch 1 commit ahead of origin/main) and doctor failed with the identical refusal — the same two dangling hook symlinks, the same remedy naming git-hook.sh. Then origin/main moved to 5c510fa and now carries .claude/hooks/git-hook.sh itself: the codemod-bash-rego-transform branch landed.

So the sequence was:

	tree	doctor
lap 4	speculative, base = the codemod branch	dangling hooks
lap 5	no speculation, 1 commit on real main	dangling hooks, identically
after	main itself carries the rename	—

The speculation was a CORRECT bet. It linearized onto "the main that is about to exist", and that is exactly what that base became. The dangling symlinks were never borrowed breakage — they were a real environment change arriving a few minutes early, and speculation showed it to me before main did.

Read properly, lap 4 is speculation working as designed, not a cost of it. The lap was still lost, but to the same defect that would have cost it regardless: a rename of a hook target does not re-link an existing clone. .git/hooks/* is created once at session start and nothing re-points it when the target moves under a git pull. doctor catches it and names the remedy (.claude/hooks/session-start.sh, which fixed it here and returned doctor: environment consistent), so the mechanism is sound and only the sequencing is unattended — every clone alive across that rename hits this once.

What survives for this row from lap 4: nothing. It is struck from the tally. The corrected count for this session is three laps lost, of which two were the disk (CLOUD-861) and one was a speculative base whose failure remains unresolved (CLOUD-466). The sentence "in this session, every verify failure land attributed to the author was in fact environmental or borrowed" also does not survive: lap 5's was environmental and genuinely the author's to fix, and fixing it took one documented command.

This is the second attribution on this row asserted and then retracted the same day, both by me, both from a sample that did not separate the variable — CLOUD-732's shape twice over. The pattern in both: a failure appeared on a speculative tree, and "speculative" was treated as the explanation because it was the salient difference, without running the arm where it is absent.

CLOUD-926 Fleet dispatch: everything outside CLOUD-911 — seven bundles, seven lands, and the lease already serializes them

The complement of CLOUD-911, bundled for the minimum number of lands. CLOUD-911 owns the bash retirement in two PRs; this row owns everything else, and it is written to the same economics: the landing lease is fleet-wide and charges per PAID land — a lap that reaches CI buys ~17 job-minutes, a lap that loses the lease or finds main already moved is free and refunded. So the objective function is number of paid laps, and the constraint on bundle size is not conflict surface but how confident verify is about the diff. §"Why five" carries the correction; the sections after it carry what follows from it.

Seven bundles, not five — the title said five until 2026-08-22 23:1x, while §Reconciliation below had already added PR-F and PR-G. A headline contradicting its own table is the defect CLOUD-923 records, so the title is corrected rather than left for a reader to reconcile.

The scope, stated before the plan, because it is bigger than a bundle

Measured 2026-08-22: 251 open rows — 99 Todo, 152 Backlog. Minus CLOUD-911's eleven, that is ~240 rows, which is the roadmap rather than a dispatch.

This row bundles the Todo set only, and the reason is a gate, not a preference. graph-check enforces Todo ⇒ ready-lint exit 0, so a Backlog row is not pullable and cannot enter a bundle without grooming first. Grooming is the largest available lever and it costs zero CI runs — it is board-only work, no branch, no lease, no matrix. 152 rows of it. Any session with no lease can do it in parallel with every bundle below.

Why five, and what sets the ceiling

Corrected in place 2026-08-22 23:1x. The first version of this section had the causality backwards, and the §Reconciliation below reached the same conclusion independently from charge_wait.

It read: "land's LAND_MAX_LAPS is 2. A bundle whose rebase surface is wide enough to need a third lap stops... So bundles are drawn to be file-disjoint, because a conflict is what turns one lap into three." Both halves are wrong.

Lapping is main moving, not files overlapping. main is fast-forward only, so the bot refuses the instant the branch stops being a direct descendant — whether or not the changes overlap (land.sh:5-12). Two branches touching entirely different files lap exactly as often as two touching the same one.

A lap is metered only when it reaches CI. land.sh:143-149: "A lap is METERED: it buys a CI matrix, measured at ~17 job-minutes. A lease wait is FREE: a conditional poll against a ref, no runner" — and the trade the defaults exist to express is "MANY FREE WAITS, FEW PAID LAPS." max_laps=2 bounds paid laps; max_waits=64 (:154-158) buys "~2h at the observed 2-5 minute lease turn — and waiting that long costs nothing but wall clock."

So LAND_MAX_LAPS is not a size cap. It is one try plus one retry of CI-spending attempts, and what exhausts it is a bundle that reds twice, not one that rebases often.

What disjointness actually buys, and it is worth keeping for this: freedom from the one thing that stops land — "The only stop is a rebase that conflicts", the single step needing a human decision. That is a don't-stall property, not a CI saving. The table below is a wall-clock estimate of serialized lands, not a CI-spend estimate:

bundling	lands	pure landing time at p95
one row per PR (≈54 Ready code rows)	~54	~10.5 h
five bundles	5	~58 min
five bundles + CLOUD-911's two	7	~82 min

The one lever on CI spend is mise run verify green before readying, and it is free. A red lap re-drafts the PR, the local fix costs nothing, and the next lap readies again — buying a second matrix. So the sizing question is not "how wide is the file domain" but "how confident is verify about this diff". One paid lap buys the 18 names in CI_REQUIRED_CHECKS (mise.toml:253).

Draft iteration is free, including for the two bundles that edit workflows

Verified rather than assumed, because it decides whether PR-A and PR-C can be developed cheaply: ci.yml:56, :372, :470 and zizmor.yml:71 all carry if: github.event.pull_request.draft == false. CLOUD-240's hole — a draft touching a workflow still spending a runner, which zizmor.yml had "for its whole life" — is closed. zizmor is also path-filtered to .github/workflows/** + action.yml (zizmor.yml:30), so PR-B and PR-D produce no run for it at all, and perf-gate exits clean without building when the diff touches no crate source, manifest or lockfile.

So every bundle iterates at zero CI cost until it readies. PRs start as drafts and stay drafts until the chain is complete.

Do not build a landing protocol — the lease already is one

The obvious inference from "lands serialize" is to hand-serialize the readies: ready one branch at a time, never while another holds the lease. That work is already done and re-doing it is a known defect.

charge_wait (land.sh:377-385) refunds a lap lost to a held lease or to a main that had already moved — "Both must refund the lap — a busy fleet would otherwise exhaust LAND_MAX_LAPS on waits." So all seven bundles may call land concurrently: the losers take free, refunded waits up to ~2h of queue depth, and nobody burns a matrix waiting their turn. Measured precedent on #302 with four active sessions: 5 waits lost and 3 laps entered in 22 minutes (land.sh:147).

Hand-serializing would be exactly the failure .claude/rules/toolchain.md records against CLOUD-238: an agent inferring landing is "a race I keep losing" and batching against the design, when "batching removes no refusal and only makes each lap bigger." AGENTS.md stands unmodified — run the lifecycle tasks as written, never wrapped in bespoke retry or pre-check logic.

The dispatch instruction is therefore the plain one: each bundle runs mise run linear-check, then mise run land backgrounded, and lets the lease arbitrate.

The two disjointness walls

Wall 1 — bundle 1 is in flight. PR #660 owns facts.rs, rules.rs, policy.rs, git.rs, schema/*, mise-tasks/mutant.sh, mise-tasks/test*, tests/*.bats. Any row in those files either joins that PR or waits for it. That is what puts PR-E last.

Wall 2 — bundle 2 is a demolition. CLOUD-910 deletes up to 20 tree-scoped gates and their suites. Fixing a bash gate that bundle 2 then deletes is wasted work and a guaranteed conflict.

The load-bearing distinction, and it must be re-derived rather than trusted: the board gates (graph-check, ready-lint, ready-cites-check, board-sweep, board-write-record, closing-key-check, landed-check) are pure functions of piped stdin, not tree-scoped rows, so bundle 2's set does not reach them. That is the argument for PR-A and PR-B being safe to land before or beside bundle 2. CLOUD-911 says bundle 2 re-derives its exact set at wave start; whoever claims PR-A or PR-B must intersect their file list against that derivation at claim time and drop any collision onto CLOUD-910.

Three meta-gates decide whether this strategy is honest at all

This is the part that changes the order, and it is worth more than any single bundle's content.

1. CLOUD-674 — closing-key-check never checks that the body closes every key the branch served. A bundle PR carrying twelve rows and naming three in its body strands nine: they never reach In Review, and the gate reports a clean pass. Every bundle below is exposed to this. It is the row that makes "as many tickets per PR as possible" a safe instruction instead of a silent data-loss instruction, and it goes in the first PR.
2. CLOUD-827 — nothing prices a prose-only branch. Two sentences of doc comment buy a full CI matrix. PR-D is almost entirely prose, so landing 827 first is what makes PR-D nearly free. Ordering, not taste.
3. CLOUD-886 — test:bats globs mise-tasks/**, so one sentence runs 151 suites. The largest per-lap cost driver on the board, and it is already inside CLOUD-911 bundle 1, so nothing here needs to duplicate it. Named so nobody bundles it twice.

PR-A lands under the broken 674, so it must name all eight of its keys by hand. After it lands, the gate enforces what this row currently asks an author to remember.

The bundles

#	Bundle	Rows	File domain	Lands
A	the landing floor	674, 827, 859, 903, 904, 465, 464, 727	mise-tasks/land.sh, ci-wait.sh, landed-check.sh, closing-key-check.sh, tests/land.bats, .github/workflows/*	1
B	the board gates	920, 921, 923, 678, 477, 634, 806, 453, 829, 771, 599, 735, 729, 698, 854	mise-tasks/*-check.sh (board arm), board-sweep.sh, board-write-record.sh, their suites	1
C	SBOM / release conformance	628, 629, 630, 631, 664, 666, 667 (+ parent 608)	mise-tasks/sbom*, ntia-check, syft config, release workflows, Cargo.toml metadata	1
D	front door + prose	869, 402, 871, 633, 680, 788, 326, 605	README.md, AGENTS.md, .claude/rules/*, remedy strings	1
E	engine / fact model	359, 360, 756, 760, 762, 914, 787, 594, 614, 372, 437, 882, 740 (924 and 925 moved to PR-G, see the reconciliation below)	facts.rs, rules.rs, policy.rs, lib.rs, git.rs	1

PR-C's bundle is forced by the board rather than chosen. CLOUD-631 promotes sbom-ntia-conformance from warn to deny in the change that makes it pass — that is its own acceptance clause, so it cannot be a separate PR from 628/629/630/664/666/667. A rare case where the cheapest bundling is also the only correct one.

PR-E's one real hazard is CLOUD-360. Its library half narrows pub mod → pub(crate) mod, which deletes public API and breaks ~432 integration tests by design — that row treats the breakage as the deliverable. It is the widest blast radius on the board and it is what could push PR-E past the two-lap cap. Keep it in PR-E as the last commits, not first: splitting it out buys a sixth land, and the tests it breaks are all inside the same PR's diff, so they cannot conflict with anything else. Its two halves are independently landable and the row says so.

The order, and why each step is a CI saving rather than a preference

1. PR-A. Fixes 674 (every later bundle's tail stops being stranded) and 827 (PR-D stops buying a matrix). Its content is worth less than its position.
2. PR-C and PR-D developed in parallel. (An earlier version of this line said "landed back to back — fully disjoint domains, so neither rebases the other". False: they queue on the lease like everything else, and whichever lands second rebases onto the first whether or not they share a file. Disjointness spares them a conflict, not a rebase.)
3. PR-B. The widest bash bundle; intersect against bundle 2's derived set first.
4. CLOUD-911 bundle 1 lands, then PR-E, then CLOUD-911 bundle 2.

The rows that need no PR at all — clear these now, at zero CI cost

Two classes, ~30 rows, and both are pure velocity because they never acquire the lease:

• Research rows. Non-negotiable rule 7 sends research to Linear, not a repo docs/ tree, and no-docs-tree fails on any tracked docs/ path. So a research row's deliverable is a Linear artifact and it lands no commit: 264, 586, 913, 915, 472, 75, 134, and in Backlog 131, 737, 500, 528, 124, 128, 130, 600, 677, 591, 466, 459, 366, 355.
• Parent and coordination rows, which CLOUD-735 shows have both gates out of In Progress unreachable by construction — they open no PR and land no commit: 14, 18, 608, 784, and in Backlog 656, 703, 607, 632.

CLOUD-735 applies to this row too: leave it in Todo and close it by hand once the five bundles are away, rather than pulling it and stranding it.

What this row is doing by hand

CLOUD-459 — "the fleet lands in lease-arrival order, not in least-conflict order: no branch knows the rebase cost of the ordering it is queuing into." The disjointness partition and the ordering above are that computation, done by hand against one snapshot. It is stale the moment main moves, which is the argument for 459 rather than for re-typing this table.

Refinement — Ready

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

• Source of truth (§1). The board and the tree. The bundle membership is a partition of the Todo set as measured on 170c7c4; the file domains are what decide it. If this row and the tree disagree, the tree is right and this row is stale.
• Computable predicate (§2). For each bundle: mise run graph-check over its piped closure prints every member on the frontier or excluded behind a named blocker, and mise run ready-lint exits 0 for every member. For the partition itself: the five file-domain lists are pairwise disjoint, and none intersects CLOUD-911 bundle 2's derived set — checked with Glob/Grep at claim time, since no-tool-substitution refuses a shell scanner aimed at a repo path.
• Effect (§3). free — a tracker record. Nothing is resolved, built or spawned.
• Generated artifacts (§4). None.
• Output / exit (§5). No command surface is touched.
• Commit / bump (§6). none — this row lands no commit.
• Test obligation (§7). None of its own; each bundle's rows carry theirs. The two claims here that could be wrong are the disjointness of the five domains and the exclusion of the board gates from bundle 2's set. Both are falsified by running the §2 checks, and both must be re-run at claim time rather than trusted from this body.
• Blockers (§8). None. PR-E waits on CLOUD-911 bundle 1 by file domain rather than by relation, because that is a conflict cost and not a dependency — recorded here so nobody encodes it as a false edge.

Reconciliation, 2026-08-22 22:0x: six Todo rows are in no bundle above, and two are double-booked

This row and the capture/mediated-call groom were written within minutes of each other and disagree. Recorded here rather than in either author's chat, because a partition that two records describe differently is worse than either description alone.

The gap: six rows the five bundles do not contain

917, 918, 919, 892, 893 and 312 are absent from PR-A through PR-E. All five of the first were already Todo when this row measured "99 Todo", so this is a gap in the partition rather than a scoping decision — and §2's disjointness predicate cannot catch it, because a partition can be pairwise-disjoint and still not cover.

They are two further bundles, drawn on the same economics:

#	Bundle	Rows	File domain	Lands
F	the capture spine	917, 918, 919, 893	capture.rs, cli.rs, surface.rs, config.rs, doctor.rs, hook.rs, lib.rs (one call site), schema/*	1
G	the mediated-call retirement	924, 925, 892, and CLOUD-312's inventory rows 1–8 and 10	rules.rs, budget.rs, stop.rs, drain.rs, batten.toml, .claude/settings.json, nine mise-tasks/*.sh deletions + their suites	1

PR-F is disjoint from A–E except for CLOUD-787 — see the correction at the foot of this body — and from CLOUD-911 bundle 2, and depends on nothing. It is the one bundle on the whole board that can land immediately — worth taking first for that reason alone, and it should land while #660 is still a draft, since a draft rebase costs zero CI and a green one costs a lap.

PR-G waits on CLOUD-911 bundle 1, and by dependency rather than by file domain — which is the opposite of PR-E's reason and is worth distinguishing. Every sibling-script deletion in it owes CLOUD-892's §2 obligation (the rule's output reproduced from config before the script dies, proved by replaying the dying suite's own fixtures). That replay is CLOUD-909 and the mapping ratchet is CLOUD-908, both inside bundle 1. So PR-G's wait is a real edge, not a conflict cost.

The double-booking: 924 and 925

PR-E claims them; PR-G needs them. They belong in PR-G, on two grounds:

1. The rows they unblock are in PR-G. CLOUD-312's rows 4 and 5 are blockedBy 924, row 6 is blockedBy 925. Splitting an instrument from its only consumers buys a land and gains nothing.
2. It makes PR-E smaller where PR-E is most at risk. This row already names CLOUD-360 as the widest blast radius on the board — ~432 integration tests broken by design — and "what could push PR-E past the two-lap cap." Shedding two rows that pull in rules.rs and the generated schema is a straight reduction in that risk.

PR-E's cell above is corrected rather than left to a reader to reconcile.

One refinement to the lap-cap argument, which strengthens it

§"Why five" reads LAND_MAX_LAPS = 2 as a bound on rebase surface. Read charge_wait (land.sh:383) beside it: a lap lost to a held lease or to a moved main is refunded — both, explicitly, so "a busy fleet would otherwise exhaust LAND_MAX_LAPS on waiting alone and give up without ever having attempted."

So the cap is not a rebase budget. It is two CI-spending attempts per PR: one try plus one retry. The conclusion holds and gets sharper — what exhausts the cap is a bundle that reds twice, not one that rebases often. That relocates the sizing question from "how wide is the file domain" to "how confident is verify about this diff", which is why the one arm where a local green does not clear CI matters more than conflict surface: perf-compare is a ratio and a dev container's baseline is ~3.5x CI's.

Net effect

Five lands become seven (A, F, C, D, B, then 911 bundle 1, E, G, 911 bundle 2 — F insertable anywhere before the rest). PR-E sheds two rows. Nothing else in the partition moves.

The ordering argument in §"The order" is unchanged and still right: PR-A first for CLOUD-674 and CLOUD-827, whose positions are worth more than their content.

---

Readiness, run 2026-08-22 23:3x — NOT ready. Four blockers, each with an owner

plan-fleet.md §2 prescribes a three-source subtraction before dispatch — live sessions, open PRs with their file lists, and In Progress assignees. It had not been run. Running it found four blockers, two of which would have wasted a land.

1. Ten bundle rows are assigned, so claim-check refuses

claim-check exits non-zero on not-todo, assigned, or has-pr. Assigned refuses even in Todo.

bundle	assigned rows
PR-A	465, 464
PR-B	453, 477
PR-D	605, 402
PR-E	437, 594, 372
PR-G	312

All to alec@button.is. This is CLOUD-911's wall reproduced — it hit the same thing on CLOUD-480 and concluded "Releasing them is the cheaper move." Human action: release or reassign; otherwise each bundle ships short and says so on the row it dropped.

The same read clears a worry: the five In Progress rows (911, 907, 908, 883, 876) are all CLOUD-911's. No bundle here contains an In Progress row.

2. PR-A collides with open draft #651, which already implements CLOUD-904

#651 (claude/ci-performance-degradation-rplznx, draft, no live session) changes exactly mise-tasks/land and tests/land.bats — PR-A's core domain — and its subject is CLOUD-904: "the lap cap said stop, and stopping is how a branch stops landing." It already carries a #MUTANT lap-cap-may-read-as-stop row and a bats case.

Take that branch over rather than opening a new one. It is a draft, so iterating is free, and adding PR-A's other seven rows costs zero extra lands. A fresh branch in the same two files buys a guaranteed conflict and a second land.

It is stale against a rename, and that is resolved first. Main carries mise-tasks/land.sh (verified by Glob: land.sh, land-lock.sh, landed-check.sh, land-divergence.sh, land-divergence-assert.sh, land-lock-check.sh). #651 modifies mise-tasks/land, a path that no longer exists — it predates CLOUD-865's rename, the one CLOUD-902 records dangling the installed hook symlinks. So its rebase hits a rename conflict on both files, which is the one thing that stops land. Re-apply its two hunks onto land.sh and tests/land.bats; do not merge.

3. PR-C collides with #572, which is already readied

#572 is renovate's syft 1.51.0, and it is not a draft — it is spending CI now. PR-C is the SBOM bundle and syft generates the artifact CLOUD-664 measured (244 components for 198 distinct things) and CLOUD-666 blames. A syft bump moves those numbers. PR-C lands after #572, or its measurements are taken against a tool version that is no longer installed.

4. The partition is already stale, by design

A live session (claude/rego-gate-architecture-wr7o5e, idle and blocked on a question) reports "7 independent tasks identified" and names CLOUD-932 and CLOUD-936 — both filed after this row measured 99 Todo. The capture session added PR-F and PR-G. This is CLOUD-459's finding about hand-computed orderings, and §"What this row is doing by hand" already says the table is stale the moment main moves. Re-run the frontier at dispatch time; do not paste a prompt built on this snapshot without it.

What IS verified

• This row: ready-lint exit 0, graph-check board coherent over the closure.
• The landing model, read from source rather than reasoned: paid laps only, contention refunded, draft iteration free including the workflow bundles (zizmor.yml:71).
• PR-B and PR-D collide with nothing. #659 touches only .serena/memories/workflow/board-states.md, so it does not reach PR-D's README.md / AGENTS.md / .claude/rules/** domain.
• create_session is refused upstream (CLOUD-734, Done, carries the measurement) and every live session is human-opened. So the prompts below are pasted by a human, one session each.

---

Dispatch prompts — one block per bundle, pasted into one session each

Each block is standalone; the workflow contract is repeated verbatim in every one and the repetition is the point. CLOUD-728 measured five bundles coming up unsupervised because a human pasted one quoted block and dropped a shared contract.

PR-F and PR-G are not here — they belong to the capture/mediated-call dispatch record, whose author owns their prompts.

Bundle A — the landing floor

You are bundle A of the CLOUD-926 dispatch in the Batten repo. Read CLOUD-926
first: it carries the landing economics, the readiness blockers and why your
position in the order matters more than your content.

READ AGENTS.md BEFORE ANYTHING ELSE. It is your standing authorization to carry
work to landed-and-verified WITHOUT asking. A session that has not read it stops
after the edits and waits, which is the defect. Then read
mem:workflow/agent-fanout, mem:workflow/board-states, and
.claude/rules/toolchain.md — your surface is the lifecycle tasks.

DO NOT OPEN A NEW BRANCH. Take over the existing draft:
  claude/ci-performance-degradation-rplznx  (PR #651, no live session)
It already implements CLOUD-904 — a #MUTANT row plus a bats case. Opening a fresh
branch in the same two files buys a guaranteed conflict and a second land.

FIRST TASK, before any new work: that branch is STALE ACROSS A RENAME. It
modifies mise-tasks/land, and main carries mise-tasks/land.sh (CLOUD-865's
rename; CLOUD-902 records what else it broke). Its rebase hits a rename conflict
on both files, which is the ONE thing that stops land. Re-apply its two hunks
onto mise-tasks/land.sh and tests/land.bats by hand. Do not merge.

THE CHAIN, in order, and the order is dependency not taste:
  CLOUD-674 -> 827 -> 904 (already done) -> 859 -> 903 -> 727 -> 465* -> 464*
- 674 FIRST. closing-key-check never checks that the body closes every key the
  branch served, so every later bundle in this campaign strands its tail until
  this lands. Your position is worth more than your content.
- 827 SECOND. Nothing prices a prose-only branch, so bundle D currently buys a
  full CI matrix for eight prose rows. Landing this makes that nearly free.
- 859, 903, 727 are landing-lifecycle defects in the same files.
- 465 and 464 are ASSIGNED and claim-check will refuse them. Do not work around
  the gate. Write the refusal on each row and skip it.

YOU OWN: mise-tasks/land.sh, ci-wait.sh, landed-check.sh, closing-key-check.sh,
land-lock.sh, tests/land.bats, .github/workflows/**
DO NOT TOUCH: facts.rs, rules.rs, policy.rs, git.rs, schema/** (PR #660 holds
them), mise-tasks/*-check.sh board arm (bundle B holds it).

ONE branch, ONE draft PR, all rows in it. Sanctioned shape — CLOUD-661 retired
one-PR-per-ticket and CLOUD-502 is Canceled.

THREE COSTS OF THE ONE-PR SHAPE. The first destroys work silently:
1. THE BRANCH MUST NOT NAME A TICKET. closing-key-check passes on the FIRST
   closing key it finds (CLOUD-527) and branch-name precedence beats the PR body
   — measured: a branch naming one issue moved that issue and left the others
   untouched. Your branch name is a domain name, which is already true of the one
   you are taking over. Close EVERY key in the PR body. Check the board after the
   merge. You are landing 674 under the broken gate, so you carry it by hand.
2. The board reports N units for one contender (graph-check counts In Progress).
   A reporting artifact, not a refusal.
3. One failure holds the batch.

PER-ROW LOOP: mise run claim-check (get_issue payload on stdin) -> claim and
assign yourself -> plan THIS ROW ONLY -> build -> mise run verify -> commit ->
next row. Do NOT plan the whole chain up front; a later row's shape depends on
what the earlier one lands.

ONCE, after the last commit: mise run linear-check, then mise run land
BACKGROUNDED. Do not ready by hand — land readies after its push. Do not wrap
land in retry or pre-check logic and do not hand-serialize against the other
bundles: the land-lock lease refunds a lap lost to contention or to a moved main
(land.sh:377-385), so waiting costs nothing while a paid lap costs ~17
job-minutes. main advancing under you is the loop working (CLOUD-238).

CI SKIPS DRAFTS, including for workflow changes (zizmor.yml:71). Open the draft
immediately and stay draft until the chain is done — iteration is free. verify
green before readying is the ONLY lever on CI spend. perf-compare is a RATIO and
a dev container's baseline is ~3.5x CI's, so a local green does NOT clear it.

KEEP GOING. A row you cannot claim is written on the issue and skipped, never a
reason to halt. The board and the PR are the report; do not stop to narrate.
UPDATE CLOUD-926's progress section at every commit: branch, PR number, rows
done. Your container can be reclaimed; chat does not survive it.

Bundle B — the board gates

You are bundle B of the CLOUD-926 dispatch in the Batten repo. Read CLOUD-926
first: it carries the landing economics and the readiness blockers.

READ AGENTS.md BEFORE ANYTHING ELSE. It is your standing authorization to carry
work to landed-and-verified WITHOUT asking. A session that has not read it stops
after the edits and waits, which is the defect. Then read
mem:workflow/agent-fanout, mem:workflow/board-states, and
.claude/rules/toolchain.md.

BRANCH: claude/board-gates-bundle  (a DOMAIN name, never a ticket name — see the
three costs below).

FIRST TASK, before any code: intersect your file list against CLOUD-910's derived
retirement set. That wave deletes up to 20 TREE-SCOPED gates. The board gates are
pure functions of piped stdin rather than tree-scoped rows, which is the argument
that your set survives — but CLOUD-911 says bundle 2 re-derives its set at wave
start, so verify rather than trust it. Any collision moves onto CLOUD-910. Take
the file list with Glob/Grep: no-tool-substitution refuses a shell scanner aimed
at a repo path.

THE CHAIN, cheapest-enabling-first:
  CLOUD-921 -> 678 -> 477 (ASSIGNED) -> 920 -> 923 -> 806 -> 634 -> 453
  (ASSIGNED) -> 829 -> 771 -> 599 -> 735 -> 729 -> 698 -> 854
- 921 first: released gates graph-check and ready-lint behind it, so a tag-less
  clone judges NOTHING. Every other row here is easier to verify once the sweep
  actually reaches the gates.
- 678 and 477 next: both starve a row off the frontier, so fixing them changes
  what the queue reports for everything after.
- 920 and 923 are the two gate defects filed while this partition was drawn.
- 453, 477 are ASSIGNED and claim-check will refuse them. Do not work around the
  gate. Write the refusal on the row and skip it.

YOU OWN: mise-tasks/*-check.sh (the board arm), board-sweep.sh,
board-write-record.sh, graph-check.sh, ready-lint.sh, ready-cites-check.sh, and
their bats suites.
DO NOT TOUCH: mise-tasks/land.sh, ci-wait.sh, landed-check.sh,
closing-key-check.sh, .github/workflows/** (bundle A holds them); facts.rs,
rules.rs, policy.rs, git.rs, schema/** (PR #660).

ONE branch, ONE draft PR, all rows in it. Sanctioned shape — CLOUD-661 retired
one-PR-per-ticket and CLOUD-502 is Canceled.

THREE COSTS OF THE ONE-PR SHAPE. The first destroys work silently:
1. THE BRANCH MUST NOT NAME A TICKET. closing-key-check passes on the FIRST
   closing key it finds (CLOUD-527) and branch-name precedence beats the PR body
   — measured: a branch naming one issue moved that issue and left the others
   untouched. Close EVERY key in the PR body and check the board after the merge.
   CLOUD-674 is the gate that should catch this and it is unfixed unless bundle A
   has landed; assume it has not.
2. The board reports N units for one contender. A reporting artifact.
3. One failure holds the batch — and this is the widest bundle, so keep each row
   a separate commit and keep verify green as you go.

PER-ROW LOOP: mise run claim-check (get_issue payload on stdin) -> claim and
assign yourself -> plan THIS ROW ONLY -> build -> mise run verify -> commit ->
next row. Do NOT plan the whole chain up front.

ONCE, after the last commit: mise run linear-check, then mise run land

paid lap costs ~17 job-minutes. main advancing under you is the loop working
(CLOUD-238).

CI SKIPS DRAFTS. Your diff touches no workflow and no crate source, so zizmor
produces no run at all and perf-gate exits clean without building — your matrix
is genuinely smaller than the engine bundles'. Stay draft until the chain is done.

KEEP GOING. A row you cannot claim is written on the issue and skipped, never a
reason to halt. UPDATE CLOUD-926's progress section at every commit: branch, PR
number, rows done.

Bundle C — SBOM / release conformance

You are bundle C of the CLOUD-926 dispatch in the Batten repo. Read CLOUD-926
first: it carries the landing economics and the readiness blockers.

READ AGENTS.md BEFORE ANYTHING ELSE. It is your standing authorization to carry
work to landed-and-verified WITHOUT asking. A session that has not read it stops
after the edits and waits, which is the defect. Then read
mem:workflow/agent-fanout, mem:workflow/board-states, and
.claude/rules/commits.md — you touch release config.

BRANCH: claude/sbom-conformance-bundle  (a DOMAIN name, never a ticket name).

WAIT FOR PR #572 FIRST. It is renovate's syft 1.51.0 and it is ALREADY READIED,
so it is spending CI now. syft generates the artifact CLOUD-664 measured (244
components for 198 distinct things) and CLOUD-666 blames. A syft bump moves those
numbers, so every measurement you take before it lands is against a tool version
that will not be installed. Re-derive the component census on the new syft as
your first act, and if the numbers moved, say so on CLOUD-664 rather than
carrying its figure forward.

THE CHAIN, and the last row is forced to be last:
  CLOUD-666 -> 664 -> 630 -> 629 -> 628 -> 667 -> 631
- 666 first: fsct3-min requires an SPDX 3 field syft cannot emit, so ntia-check
  is GUARANTEED red and blames the lockfile for it. Until that is fixed you
  cannot tell a real conformance failure from the permanent one.
- 664 next: the component count is wrong (one entry per workflow reference, the
  root package twice, a spurious ./action), so every downstream enrichment row
  is enriching phantom entries.
- 630, 629, 628 are the supplier / copyright / license enrichment rows. 629 is a
  DECISION row — whether the registry cache is a defensible source for copyright
  text — so settle it before 628 builds on it.
- 667 is the 9 SHA-pinned GitHub Actions.
- 631 LAST, and this is not a preference: it promotes sbom-ntia-conformance from
  warn to deny "in the change that makes it pass", which is its own acceptance
  clause. It cannot be a separate PR and it cannot come before the rows that make
  it pass.

YOU OWN: mise-tasks/sbom*, ntia-check, the syft config, the release workflows,
Cargo.toml package metadata.
DO NOT TOUCH: mise-tasks/land.sh, ci-wait.sh, closing-key-check.sh (bundle A);
mise-tasks/*-check.sh board arm (bundle B); facts.rs, rules.rs, policy.rs,

ONE branch, ONE draft PR, all rows in it. Sanctioned shape — CLOUD-661 retired

Bundle D — front door and prose

You are bundle D of the CLOUD-926 dispatch in the Batten repo. Read CLOUD-926
first: it carries the landing economics and the readiness blockers.

READ AGENTS.md BEFORE ANYTHING ELSE. It is your standing authorization to carry
work to landed-and-verified WITHOUT asking. A session that has not read it stops
after the edits and waits, which is the defect. Then read
mem:workflow/agent-fanout and mem:workflow/board-states.

BRANCH: claude/front-door-bundle  (a DOMAIN name, never a ticket name).

LAND AFTER BUNDLE A IF YOU CAN. Your diff is almost entirely prose, and nothing
currently prices a prose-only branch — CLOUD-827, inside bundle A, is what stops
two sentences of doc comment buying a full CI matrix. If A has landed, your
matrix is much smaller. If it has not, proceed anyway; do not idle waiting.

THE CHAIN:
  CLOUD-869 -> 402 (ASSIGNED) -> 871 -> 680 -> 633 -> 788 -> 326 -> 605 (ASSIGNED)
- 869 first: the front door tells the reader the repository is private and cites
  four documents they cannot open. It is the only row here a stranger sees.
- 402: batten --help leads with a retired policy-engine claim, a second copy of
  the crate description with nothing asserting they agree. ASSIGNED — expect a
  claim-check refusal.
- 871 then 680: gate remedy text is unaudited prose that steers the agent, and
  one sentence steered it into an unrecoverable action. 680 is the same class:
  an override ask presented as a menu of routes rather than the binary decision
  it is. Do 871 first — it is the general audit, 680 is one instance.
- 633, 788, 326 are the recall / threshold / durable-home rows.
- 605 ASSIGNED: a user-level stop hook instructs the exact commit identity
  batten.toml denies. Expect a refusal.

AGENTS.md IS AT ITS BUDGETED LINE CEILING. policy-budget gates it plus
everything always-loaded against a token budget — it is `batten policy budget`,
and the counted set and thresholds are [budget.instructions] in batten.toml. So
an addition must DISPLACE, not append. If a change cannot fit, the content goes
to .claude/rules/ or a memory and AGENTS.md gets a pointer.

YOU OWN: README.md, AGENTS.md, .claude/rules/**, and gate remedy strings.
DO NOT TOUCH: .serena/memories/** — PR #659 holds
.serena/memories/workflow/board-states.md, and memory writes are gated: the
protected-path rule crosses .serena/memories/** with the verb table, so use
Serena's own tools and expect a deny on a shell write. Also not
mise-tasks/land.sh or .github/workflows/** (bundle A), and not facts.rs,
rules.rs, policy.rs, git.rs, schema/** (PR #660).

ONE branch, ONE draft PR, all rows in it. Sanctioned shape — CLOUD-661 retired

A PROSE CHANGE STILL NEEDS A MECHANISM. Non-negotiable rule 2: a new rule
without a runnable gate is half a change, and prose is feedforward only. Several
of these rows are about text that steers an agent — where the row asks for a

Bundle E — engine and fact model

You are bundle E of the CLOUD-926 dispatch in the Batten repo. Read CLOUD-926
first: it carries the landing economics and the readiness blockers.

READ AGENTS.md BEFORE ANYTHING ELSE. It is your standing authorization to carry
work to landed-and-verified WITHOUT asking. A session that has not read it stops
after the edits and waits, which is the defect. Then read
mem:workflow/agent-fanout, mem:workflow/board-states, .claude/rules/rust.md and
.claude/rules/scanning.md — you edit crates/** and you will be tempted to grep.

BRANCH: claude/fact-model-bundle  (a DOMAIN name, never a ticket name).

DO NOT START UNTIL PR #660 HAS LANDED. Verify on the tree, not from this prompt:
CLOUD-911 bundle 1 rewrites facts.rs, rules.rs, policy.rs, git.rs and schema/**,
which is your entire domain. A draft rebase costs no CI, so the cost of starting
early is rework rather than money — but the rework is large, because that branch
is adding a Production axis and generating both policy-input schemas from
Fact::ALL. Wait.

THE CHAIN, and CLOUD-360 is deliberately LAST:
  CLOUD-787 -> 914 -> 762 -> 359 -> 756 -> 882 -> 614 -> 740 -> 760 -> 372* ->
  437* -> 594* -> 360
- 787 first: ReceiptFacts and KeyFacts still spell "could not look" as Option,
  so the three-valued contract is stated in one file and practised in another.
  Every row after it depends on that contract being real.
- 914 then 762: the two precision facts. 914 is position-awareness (a token in
  command position vs in a comment, a string, or the gate's own source); 762 is
  the use-graph measurement. Neither blocks 359 — both are hardenings.
- 359 then 756: 359 is the layering gate, and it is EXPRESSIBLE TODAY on
  Rule::line_sources (rules.rs, glob-selected, unparsed lines, three-valued by
  construction because an unreadable path stays in `missing`). 756 then migrates
  one of the seven hand-rolled git.rs source scans onto the same surface and
  DELETES the scan in the same change. Do 359 first: it is the worked example
  756 needs.
- 882, 614, 740, 760 are the remaining engine rows.
- 372, 437, 594 are ASSIGNED and claim-check will refuse them. Do not work
  around the gate. Write the refusal on the row and skip it.
- 360 LAST, and this is the whole sizing argument. Its library half narrows
  37 `pub mod` to `pub(crate) mod`, which DELETES public API and breaks ~432
  integration tests BY DESIGN — that row treats the breakage as the deliverable
  and the compiler as the oracle. Its two halves (visibility narrowing;
  config-deprecation grammar) are independently landable and the row says so. Put
  the narrowing in the final commits so a red there does not hold the twelve rows
  in front of it.

RE-RESOLVE EVERY file:line IN THESE BODIES BEFORE TRUSTING IT. Measured on
CLOUD-760 alone: SIX pointers in one body resolved to the wrong thing —
rules.rs:2223, exec.rs:1479 (wrong MODULE, it is outputs.rs:208), rules.rs:1544,
two secrets.rs spans and identity.rs:363. The substance held every time; only the
addresses were stale, and no gate sees this class because ready-cites-check only
judges backticked paths containing a slash. Resolve by SYMBOL NAME with Serena,
not by line number, and not with grep: surface.rs imports clap::Command bare, so
a text scan counts two different types as one (grep 14, syntax matcher 11, name
resolution 9).

YOU OWN: crates/batten/src/facts.rs, rules.rs, policy.rs, lib.rs, git.rs, and
the schema/** they generate.
DO NOT TOUCH: mise-tasks/** at all — bundle A holds the lifecycle tasks, bundle
B holds the board gates, and CLOUD-910 is deleting up to 20 of the rest.

GENERATED ARTIFACTS ARE REGENERATED, NEVER HAND-MERGED. schema/batten.schema.json
and schema/batten.local.schema.json come from `mise run fix`; derived-check and
schema-check gate both. Two merged regenerations produce a file neither branch
would have produced.

ONE branch, ONE draft PR, all rows in it. Sanctioned shape — CLOUD-661 retired
one-PR-per-ticket and CLOUD-502 is Canceled.

THREE COSTS OF THE ONE-PR SHAPE. The first destroys work silently:
1. THE BRANCH MUST NOT NAME A TICKET. closing-key-check passes on the FIRST

   untouched. Close EVERY key in the PR body and check the board after the merge.
2. The board reports N units for one contender. A reporting artifact.
3. One failure holds the batch — which is why 360 is last.

PER-ROW LOOP: mise run claim-check (get_issue payload on stdin) -> claim and
assign yourself -> plan THIS ROW ONLY -> build -> mise run verify -> commit ->
next row. Do NOT plan the whole chain up front; a later row's shape depends on
what the earlier one lands, and that is especially true here.

ONCE, after the last commit: mise run linear-check, then mise run land
BACKGROUNDED. Do not ready by hand. Do not wrap land in retry logic and do not
hand-serialize against the other bundles: the lease refunds a lap lost to
contention or to a moved main (land.sh:377-385).

YOUR MATRIX IS THE EXPENSIVE ONE. You touch crate source, so perf-gate BUILDS
both arms rather than exiting clean, and semver runs against the library surface
— 360 will need the honest `refactor(lib)!` type, which collapses to a patch
below 0.1.0 and still marks the changelog entry breaking. perf-compare is a
RATIO and a dev container's baseline is ~3.5x CI's, so a LOCAL GREEN DOES NOT
CLEAR IT; read the CI number. Run perf-gate with nothing else in flight — two
readings had to be discarded on #660 because a build or a formatter was running
alongside.

Progress (each bundle updates this at every commit — branch, PR, rows done)

• Bundle A — in flight. Branch claude/ci-performance-degradation-rplznx, PR Bundle A: the landing floor — 674, 827, 904, 903, 727 in one land #651 (draft, taken over rather than reopened). Rows landed on the branch: 674, 827, 904. Remaining: 903, 727, 859. 465/464 to be skipped with the refusal written on each row.

  Two corrections to this row's own bundle-A prompt, established by reading rather than assumed:

  1. CLOUD-904 is NOT "already done". 904 was filed reviewing Bundle A: the landing floor — 674, 827, 904, 903, 727 in one land #651 and states that PR's text must be superseded rather than merged as-is — the unconditional RUN THIS AGAIN re-arms the only brake on that CI spend, and the declared mutation s/RUN THIS AGAIN/look/ against an assertion hardcoding RUN THIS AGAIN is caught by identity and discriminates nothing. It is real work in the inherited hunk's own lines, and it must also update tests/land.bats:1111, which today asserts the refuted moving faster than a lap takes clause is present — a detail neither the prompt nor 904 names.
  2. The staleness was far worse than "a rename conflict on two files". The branch stood 1 commit past f3eb5cd while main had moved 57 commits on, and the clone was shallow, so git merge-base origin/main HEAD returned nothing at all and the two histories read as unrelated. Recovery: git fetch --unshallow, reset to origin/main, re-apply the two hunks by hand. A merge or rebase would have conflicted across far more than land.sh and land.bats.

  A defect found in mutant while establishing 674's §7, and it is wider than this bundle. mise run mutant was silently skipping declared mutations and reporting them as caught. Its row loop is fed by done <<<"$rows", so the rows sit on the shell's stdin, and bats — invoked inside the loop body — reads stdin and swallowed every row after the one it was running. Measured on claimed-keys: three declared rows, the counter reached 2, and claimed-keys-adopts-speculated was never applied while the task printed "every one caught" and exited 0. That is the defect CLOUD-418 was filed about, reproduced inside the remedy built for it, failing in the passing direction. Fixed with two </dev/null redirects; the same gate pair then reported 4 declared rather than 3. The tail of every multi-row declaration in the 55-gate set was unverified until now, and the full set is being re-run to find what was never actually caught. Whether that warrants its own row is for whoever reads this next — it is recorded here rather than left in a dead session's chat.

  Gate mechanics that cost turns and are not in the prompt: claim-check needs an issue-read-check baseline first; ready-lint answers exit 2 ("could not look") when a payload lacks relations, so a get_issue without includeRelations: true reads as a broken row rather than a missing field; and board-payloads needs BATTEN_TRANSCRIPT_FILE on this host, which has no .claude/.transcript.jsonl symlink.

Correction 2026-08-23 — §Reconciliation's "PR-F is disjoint from A–E" is false, and the row that falsifies it is bundle E's FIRST

Measured on the tree while planning PR-E, not inherited from this body.

CLOUD-787 is in bundle E and its entire deliverable is in hook.rs and stop.rs — both inside PR-F's own declared file domain (capture.rs, cli.rs, surface.rs, config.rs, doctor.rs, hook.rs, lib.rs, schema/*). The two domains intersect, and they intersect on the row PR-E has to do first.

Resolved by symbol rather than by the line numbers CLOUD-787's body carries, which are stale in exactly the way §"What this row is doing by hand" predicts:

what	the body says	resolves to
facts::Look	—	facts.rs:247-262 (Is / IsNot / CouldNotLook)
ReceiptFacts	hook.rs:1850	hook.rs:2765
KeyFacts	hook.rs:1866	hook.rs:2781
StopFacts::at_risk	—	stop.rs:86

Why this is recorded rather than escalated. §Reconciliation also says PR-F "can land immediately" and should land while #660 is still a draft, while PR-E is last behind wall 1 — so on the stated ordering the collision resolves before PR-E starts, and the partition is wrong without being costly. Whoever takes PR-E re-checks PR-F's actual file list at CLOUD-787's claim time; a rebase carries a type-alias substitution, and only a same-hunk conflict is a genuine stop.

The general point, which is this row's own §2. The disjointness predicate is stated as pairwise-disjoint file-domain lists, and §Reconciliation already records that such a predicate "cannot catch" a partition that fails to cover. This is the other half: it did not catch a partition that fails to be disjoint — because the check was never run. The domains were listed, not intersected. §2 says to intersect them with Glob/Grep at claim time; that instruction is the mechanism, and this correction is what happens when it is skipped at authoring time.

CLOUD-859 `land` readies without ever requiring a review, so an unreviewed or unanswered head buys the matrix — replayed, it fires on 89 of the last 100 merges

Why

land readies a PR without ever asking whether anyone reviewed it. Three gates run before the ready in mise-tasks/land — deferral-check, filed-here-check, closing-key-check — and none of them is about code review. The ready is what starts the matrix, so an unreviewed head, or one carrying findings nobody answered, spends CI exactly as readily as a reviewed one.

Until CLOUD-847 landed there was nothing to gate on: the draft phase is the free phase and nothing reviewed it. That row put .coderabbit.yaml on main and measured what a review can be made to say. This row is the other half — the gate that reads it.

Replay — the firing rate, before the severity is chosen

The predicate below, replayed over the 100 most recently merged PRs (2026-08-19 to 2026-08-22), read from reviews + reviewThreads exactly as the rule would read them:

• corpus: 100 merged PRs
• fired: 89 — 21 carrying no review from anyone but the author, 68 carrying unresolved threads
• passed: 11 (docs(memory): a closing key beats the branch name; a mention does not #639, chore: release v0.0.102 #636, ci(review): make a review exist in the free draft phase, and a verdict a gate can read #623, perf(ci): the warm job compiled 145s to write nothing on every merge but one #628, feat(hook)!: project the resolved fact set into the policy input #620, fix(run-shape-guard): register it, and refuse a timer wearing a wait's clothes #605, perf(ci): narrow the two PR workflows CLOUD-180's scope missed, and gate the absence #600, fix(connector-allow-resolve): give settings the seam config already had #568, ci(deps): re-read the closing key at the moment the lane lands #565, feat(trust): a census over every config field, and the coverage it forces #543, fix(hooks-wiring-check): count the PreToolUse commands that are not batten's (CLOUD-713) #540)
• open threads across the fired set: 163; worst single PR 9 (ci(deps): land the bot's PRs unattended, and retire the second bot #542), then 7 (Three defects in the landing loop, each a mechanism blind outside its own scope #641, feat(policy): the policy spine — IO-free pin, per-predicate ids, one composed engine, the tree surface, presets, whole-set analysis #613)
• false positives: 0, and the reason is structural rather than lucky. The predicate reads two facts — does a non-author review object exist, is any thread unresolved — and never estimates. Every firing names a review that is absent or a thread that is open, both checkable on the PR today. This is the same argument CLOUD-631's per-SHA replay makes: a checker that DECIDES has no false-positive rate to measure, only a desirability question, and that question is this row's subject rather than a defect in its predicate.
• the unit is deliberate. deny-without-replay's remedy names git rev-list origin/main; this predicate is scoped to a pull request, so a commit-wise replay would count commits the rule never judges. PRs are the population.

An 89% firing rate is the finding, not a reason to soften the rule: 21 of those merges had nothing but their author look at them.

Before CLOUD-847 landed, reviewDecision was null across every sampled merge, because request_changes_workflow was off until CLOUD-847.

The single worst instance is #617: reviewed at 15:39:44, merged at 15:51:30 twelve minutes later carrying three threads that are still open today. Not an unreviewed merge — an unanswered one.

The compliance bill, stated up front — and the first figure here was wrong

The gate costs a review plus one resolution per open thread, and all of it is spent in the free phase where no matrix is running. The wait has two rates, and the row originally cited only the fast one:

• Forced, ~3 minutes. @coderabbitai full review returned in 193s on ci(review): make a review exist in the free draft phase, and a verdict a gate can read #623 and 186s on a re-review.
• Automatic, ~6–11 minutes, per push. Measured on sibling traffic after the config landed: feat(hook): end the end-of-turn runaway, and put one door in front of the hooking surface #632 5m48s, feat(board): the board-gate caller, and run-shape-guard's one movable family #631 6m49s, CLOUD-844 + CLOUD-720: the instrument taxonomy, and a typed base-ref load outcome #629 8m17s, Make the tree policy input correspond to the fact model: one acquisition, a real tracked, declared sources, lines, and a sink #633 10m42s (upper bounds — commit time precedes push). Incremental review fires on every head, so a PR that pushes three fixes waits three times.

So forcing the review is the workflow for a session that wants to land now, not a fallback for when the incremental path no-ops. Against that: 68 of the 100 replayed PRs carried findings that arrived after the ready, and every fix pushed after a ready buys a second matrix. The trade is free wall-clock for paid CI, which is the same arithmetic CLOUD-827 prices from the other side.

Where this can bind, measured

main is protected — by a ruleset, not by legacy branch protection, which is why branches/main/protection answers 404 Branch not protected and reading only that endpoint gives the wrong answer. protect-main is active, scoped ~DEFAULT_BRANCH, with bypass_actors: [] and current_user_can_bypass: never. Its rules: deletion, non_fast_forward, required_linear_history, and required_status_checks (strict_required_status_checks_policy: true) listing exactly one context — final.

There is no pull_request rule, so no required approvals and no required thread resolution: a CHANGES_REQUESTED review blocks nothing today. But an unbypassable enforcement point exists, and it takes check contexts.

Minimal capability — and the mechanism changed under this row

When this was filed, the shape was a bash task in mise-tasks/. The policy engine has since landed: a policy rule kind evaluating rego predicates over a fact set, scoped mediated_call or tree, and [[fact]] — the agent-sourced fact channel, a name plus the command that answers it, with the same string read twice so the deny that tells an agent what to run is the same string the stored record is verified against. This repo declares zero facts today, so this row is that channel's first consumer, and should say so.

Three halves now, and the first two are one predicate:

1. A [[fact]] row naming the review payload and the gh api graphql command that answers it. The engine is IO-free — defended by evaluator-closure-io-free — so a predicate needing the network cannot be rego. The fetch is the agent's; the fact is what reaches the engine.
2. A [[rule]] of kind = "policy", scope = "mediated_call", deciding over that fact. Scoped to the mediated call it denies gh pr ready for every caller — which is strictly more than the original design reached, and is why §1 below now argues the opposite of what it first argued.
3. The same predicate published as a check-run and added to protect-main's required list, which is where the guarantee is: a task an agent can skip is not a ruleset with bypass_actors: [].

Rule 1 keeps this out of the presets. The predicate names a forge, a reviewer and a query syntax; trunk-based's own header is explicit that a vendored preset "names no repository, no ref and no task". It belongs in this repository's batten.toml and a local module.

The constraint that decides whether half 2 works at all, stated precisely — the first version of this paragraph blurred it. GitHub distinguishes a skipped JOB from a skipped WORKFLOW, and only one of them is safe (Troubleshooting required status checks):

• a job skipped by a conditional reports Success and does not block merging, even when required;
• a workflow skipped by path or branch filtering leaves its checks Pending, which does block — and the docs advise against filtering a required workflow that way.

This already bites, today, before half 2 exists. Every job in ci.yml carries if: draft == false, so on a draft the required context final reports success — a green required check on a head nothing ran against. land is immune because graded_runs() reads conclusions rather than the rollup, but the ruleset is not, and any future check-based gate reading final would inherit it.

Nor is it fixable by moving the guard: there is no workflow-level if, and on.pull_request.types has no draft filter, so only path/branch filters can skip a whole workflow. The draft guard can only live at job level, which is exactly what makes it report green. So a review check must run and fail on an unreviewed head rather than skip. Prove that before wiring it into the ruleset, and never land the check and the ruleset edit in one change: protect-main has no bypass actors, so a check that fails wrongly — or a required context that no longer exists — cannot be merged past.

---

Refinement — Ready

• Source of truth (§1). One predicate, in one rego module, named by one [[rule]] row. This clause used to say the opposite and the reversal is the point: it argued the gate must live in land and never be duplicated into ready-guard, because land's internal gh pr ready is not a tool call and the hook cannot see it. That was correct for a bash gate and is what makes the policy scope worth having — a mediated_call row sees precisely the call land cannot, so the two call sites are covered by one predicate instead of two copies. land may consult the same rule early, so the refusal still arrives before the spend, but it is a caller of the predicate rather than its home.
• Computable predicate (§2). For the PR whose head is about to be readied: it carries at least one review from an author other than its own, and zero unresolved review threads. Decided in rego over the declared fact — reviews, latestReviews, reviewThreads as fetched by the [[fact]] command — plus input.call for the mediated arm. No judgement, no model verdict, and no IO inside the predicate. Two things it deliberately does NOT require, each refuted by measurement on ci(review): make a review exist in the free draft phase, and a verdict a gate can read #623: not reviewDecision == APPROVED (a forced re-review after fixing every finding went 2 to 4 open threads and never approved in 15 minutes, so a gate keyed on approval hands land to a reviewer that may never give it), and not a review whose commit equals the head (the reviewer is incremental and answers "does not re-review already reviewed commits" without producing a review object at all — a gate demanding one would deadlock). reviewDecision is reported as a pointer only.
• Effect (§3). read. The fetch belongs to the declared fact's command and the decision to the engine — the repository's standing split, agents fetch, gates decide. Obtaining the review in the first place is a write (@coderabbitai full review, the forcing form) and stays outside both.
• Output & exit (§5). Pointer-only: thread ids, the unresolved count, and the decision token, never review prose. 0 reviewed and addressed; 1 could not look (no gh, no network) and fails open, since a gate that blocks landing when GitHub is unreachable becomes the reason work cannot proceed; 2 unreviewed or unaddressed.
• Commit / bump (§6). feat(rules) — patch until 0.1.0. No longer feat(land): the deliverable is a fact row, a policy rule and a module, not an edit to the landing task.
• Test obligation (§7). Shown able to fail (CLOUD-418), and every case below was run against live PRs before this row was filed, so each has a real instance rather than a fixture:
  • refuses a head with open threads — ci(review): make a review exist in the free draft phase, and a verdict a gate can read #623 with 4 open, feat(policy): batten policy test — run a module's own test_ rules, and prove a test made each predicate fire #617 with 3, feat(policy): the policy spine — IO-free pin, per-predicate ids, one composed engine, the tree surface, presets, whole-set analysis #613 with 7;
  • refuses a head no one but the author reviewed — perf(ci): bind the warm job's install list, which is worth 163 of its 171 seconds #621, docs(memory): the blocker nobody tested, and the fuzz lockfile drift that found itself #624, docs(ci): the shared-key comment stated a fact the first warm run disproved #618;
  • passes a head whose threads are all resolved — feat(hook)!: project the resolved fact set into the policy input #620, and ci(review): make a review exist in the free draft phase, and a verdict a gate can read #623 after its six were answered;
  • vacuity, zero threads: docs(ci): the shared-key comment stated a fact the first warm run disproved #618 carries no threads and no review, and must read as unreviewed rather than "all addressed";
  • vacuity, self-review: a payload built from feat(hook)!: project the resolved fact set into the policy input #620 with the non-author reviews stripped must refuse;
  • vacuity, status: a CodeRabbit success commit status must never count as evidence — CLOUD-847's arm C measured it green over a review carrying a finding and green over a review that never ran, and it then reproduced on other people's PRs: fa88bd6, 4bbdf62, 344cd50 and 562a8e6 all read CodeRabbit = success while their reviews requested changes;
  • vacuity, skipped check: a skipped job conclusion must not read as passing — GitHub counts it as satisfied, which is why final is green on every draft today and why this check must run and fail instead of skipping;
  • decision red, threads clear: Make the tree policy input correspond to the fact model: one acquisition, a real tracked, declared sources, lines, and a sink #633 sat at CHANGES_REQUESTED with its latest review COMMENTED and one thread open. The gate must pass it once that thread is answered, and a decision-keyed gate would refuse it indefinitely — this is the live case that settles §2's choice;
  • readied while unaddressed: feat(board): the board-gate caller, and run-shape-guard's one movable family #631 was readied carrying CHANGES_REQUESTED and three open threads, which is exactly the head this gate exists to stop;
  • and the module carries its own test_ rules, in the shape the vendored presets use — one per predicate, proving each fires, since a registered module is compiled and smoke-queried on every mediated call and an untested predicate rides that path unmeasured.
• Blockers (§8). None on the board — CLOUD-847 has landed, so the verdict this reads already exists. relatedTo CLOUD-847 (the config that makes a review exist in the free phase), CLOUD-347 (review is the lifecycle step with no predicate — that row is about the board column, this one about the ready), CLOUD-240 (the landing loop's CI economy), CLOUD-827 (pricing what a branch spends), CLOUD-853 (the /fast-forward trigger merging an unverified draft — the other door).

Acceptance

• land refuses to ready a PR whose review obligation is unmet, naming the threads and never the prose.
• A PR cannot reach ready_for_review, and so cannot spend a matrix, before a review of it has been read and answered.
• The published check refuses an unreviewed head by running and failing, never by skipping, and only then is it added to protect-main's required contexts.
• Shown able to fail in both directions, including all four vacuity cases.
• The 89% firing rate is expected to fall once reviews arrive in the free phase, which is what CLOUD-847 landed; if it does not move, that is a finding for this row rather than a reason to weaken the predicate.
• The declared fact's command is the one the deny prints, verified against the stored record rather than restated in prose.

§2 IS NOT IMPLEMENTABLE AS WRITTEN — the fact channel is payload-free by construction (2026-08-23, bundle A)

Claimed this row in bundle A of CLOUD-926 and read the mechanism before writing the module. The predicate §2 specifies cannot be expressed, and the reason is structural rather than a gap someone can fill.

§2 says the rule is "decided in rego over the declared fact — reviews, latestReviews, reviewThreads as fetched by the [[fact]] command". None of those fields ever reaches rego.

facts::Sourced — the whole of what an agent-sourced record stores — is three fields:

pub struct Sourced {
    pub command: String,   // what the agent actually ran, verbatim
    pub seen_at: String,   // RFC3339
    pub rows: usize,       // "How many rows the buffer carried. A count, never the payload."
}

and facts.rs's own header says why, in the section headed "Rule 4, structural rather than careful":

A command's stdout can carry anything, which makes a result buffer the likeliest thing in the envelope to hold a secret. No byte of it is stored. rows_in reduces the buffer to a COUNT at the boundary and the count is what reaches disk, so a deny message, a -J document and everything under the state root are payload-free by construction rather than by care at each emission site.

hook::call_document confirms it at the projection site — Fact::AgentSourced projects exactly {command, seen-at, rows} and its comment reads "WHAT THE AGENT RAN, not what it printed … rows is a COUNT reduced at the boundary and no byte of the buffer is stored."

So a rego predicate over this fact can ask which command ran, when, and how many rows came back. It cannot ask whether a review's author differs from the PR's, and it cannot enumerate thread ids — which is also why §5's "pointer-only: thread ids, the unresolved count" cannot be emitted from the rule: the thread ids are not in the engine.

What IS expressible, and it is a genuine fit rather than a workaround

Put the selection in the declared command and let the count carry the verdict: the command emits a JSON array with one element per blocking condition (each unresolved thread, plus a synthetic element when no non-author review exists), and the rule denies when the record is absent or rows > 0. rows == 0 is then exactly "reviewed and addressed".

The forgery control still holds, and it is the one §"Acceptance" already asks for: Declared.command is read twice — it is what the deny prints and what the stored record is compared against — so an agent cannot substitute a laxer query without the record failing comparison.

This is a different predicate from the one §2 specifies, not a restatement of it, so it is the row's author's call rather than an implementer's. It changes §2, §5, and most of §7: every case currently phrased over a payload ("a payload built from #620 with the non-author reviews stripped") becomes a case over the command's output shape, which is testable but is a different test.

A second, independent blocker on the same path — unmeasured, and it decides whether even the count works

rows_in's own doc:

The buffer's shape is per-tool and only partly surveyed: an MCP tool returns a content-block array (measured — tests/board-write-record.bats), and a shell tool returns something this repository has not measured. Answering 0 for a shape this build cannot read would be a guessed envelope becoming a silent fact … so an unrecognised shape is could-not-look instead.

§1 specifies a gh api graphql command — a shell tool. If a Bash tool result does not match either read shape, every record is CouldNotLook, no rows is ever stored, and the rule sees a null record on every call. Under the deny-when-absent posture that is a gate that refuses every gh pr ready in the repository and cannot be satisfied by running the command it names. Measuring that is a precondition, not a detail.

Disposition

Left In Progress with the branch not carrying it. The other five rows of bundle A — CLOUD-674, CLOUD-827, CLOUD-904, CLOUD-903, CLOUD-727 — are complete, verified and pushed on claude/ci-performance-degradation-rplznx (PR #651). CLOUD-674's position is the point of that bundle (every later bundle in CLOUD-926 strands its tail until it lands), and holding five finished rows behind one whose §2 needs rewriting is the wrong trade — "one failure holds the batch" is the cost the one-PR shape already names.

What this row needs before an implementer picks it up again, in order:

1. Measure whether a Bash tool result mints a row count at all, or only an MCP tool result does. If only MCP, §1's command has to change or the channel needs a shell shape added.
2. Re-specify §2 as a count predicate over the declared command, and re-derive §5 (no thread ids available) and §7 (cases over the command's output, not over a payload).
3. Steps 2 and 3 of §"Minimal capability" — the published check-run and the protect-main required-context edit — are untouched by any of this and remain correct as written, including the ordering constraint that they never land together.

Nothing here weakens the row's finding: 89 of the last 100 merges is unchanged, and the gate is still worth building. What is wrong is the mechanism paragraph, written when [[fact]] looked like a payload channel.

CLOUD-465 `land` binds to whatever PR the branch name ever had, so the second landing on a reused branch drives the merged one

Why

mise-tasks/land:93 resolves the PR it will drive with a bare read:

pr="${PR:-$(gh pr view --json number --jq .number)}"

Bare gh pr view returns the PR associated with the current branch in any state. It has no --state open filter, so once a branch name has carried a merged PR, every later land on that name binds to the merged one.

That is not a rare shape here, it is the default one. Trunk-based development deletes the branch on merge (CLOUD-349), and the session harness pins each agent to one fixed branch name for the whole engagement. So the second landing of any session recycles a name whose previous PR is merged — and binds to it.

Observed 2026-08-12: after #366 merged, a new commit was pushed to the same branch name and a new PR #368 opened. land resolved #366 and failed with:

::error:: land: could not re-draft #366 to re-fire the ready that starts CI.

What saves it today is incidental, and that is the part worth fixing. Downstream at :747 a non-OPEN state is read as terminal, and MERGED sets landed=yes and exits 0 — i.e. land reporting a completed landing for a commit that never reached main. That path is not reachable right now only because redraft runs first and GitHub refuses to re-draft a merged PR, so the run dies before it can lie. The false completion signal is one refactor away from being live, and it is the exact failure class this repository exists to refuse: the wrong completion signal.

Refinement — Ready

• Source of truth (§1). The open pull request whose head is this branch. A merged or closed PR is finished; it cannot track new work and must not be driven.
• Mechanism (§3). Resolve with an explicit state filter and head match rather than the ambient one — gh pr list --head "$branch" --state open --json number --jq '.[0].number // empty' — so "no open PR" falls through to the error already at :94-96, which names the fix. Additionally assert the resolved PR is OPEN before the first lap, so a PR that merges underneath a running land is a stop rather than a bound-to-merged drive.
• Deliberately not in scope (§2). Auto-creating the PR when none is open: issue-guard gates gh pr create on a claimed issue key, and moving that decision inside land would route it around the gate. Also not in scope: changing the :747 terminal-state reading, which is correct for a PR that merges while land watches it — the defect is which PR got bound, not how a merge is read.
• The wider claim (§2). PR= remains the override for the one case a caller genuinely knows better.

Test obligation

Mutation-checked per CLOUD-418: with the state filter removed, a case where the branch carries a merged PR and an open one must bind the merged PR and fail. The suite's gh stub already sequences pr view responses, so both shapes are scriptable without a remote.

Commit / bump (§6): fix(land) — patch until 0.1.0 regardless of type.

Blockers (§8): none.

Acceptance

• With a merged PR and an open PR on the same branch name, land drives the open one.
• With only a merged PR, land stops with the existing "no pull request for this branch" error rather than binding it.
• A PR that merges while land is mid-lap is still read as landed, unchanged.

Skipped by bundle A of CLOUD-926 — claim-check refuses it assigned (2026-08-23)

This row is in bundle A's chain and was not worked. mise run claim-check, with this row's own get_issue payload on stdin:

CLOUD-465 assigned
::error:: claim-check: not pullable — someone is already on it.

The row is Todo with assignee: alec@button.is, so the assigned rule fires.

Not worked around. BATTEN_CLAIM_TAKEOVER=1 would have minted the receipt and was not used: that flag answers "the competitor is this branch", and here it is not — there is no branch of mine to resume and no board move of mine to undo. mem:workflow/board-states is explicit that a takeover is for a branch, not for a doubt, and that assigned's ambiguity is a reason to read the row as occupied rather than to discount it. CLOUD-430 records what discounting it costs: a full duplicate implementation, built and thrown away.

The rest of bundle A landed on claude/ci-performance-degradation-rplznx (PR #651): CLOUD-674, CLOUD-827, CLOUD-904, CLOUD-903, CLOUD-727.

A live confirmation of this row's own finding, observed while landing that bundle, and worth recording because it is the shape §"Why" predicts:

PR #651 is a branch whose name has now carried work across a container boundary. The branch was resumed in a fresh session, and mise run claim-check refused CLOUD-904 with has-pr (651) — the PR attached to the row is the one this branch is driving. That refusal is correct and is not this row's defect, but it is the same underlying fact this row is about: branch identity outlives a PR's lifecycle, and a bare lookup keyed on the branch cannot tell which PR is the live one. land:93's gh pr view --json number has no --state open filter, so the first landing on a reused name binds whatever PR that name ever had.

§"Why"'s claim that this is the default shape rather than a rare one is therefore strengthened: the session harness pins one branch name per engagement, and the fleet dispatch in CLOUD-926 hands branches between sessions by design. This row's fix — gh pr list --head "$branch" --state open plus an OPEN assertion before the first lap — is the one that makes a resumed branch safe.

One pointer that has moved: bundle A added three cases to tests/land.bats and took land.sh's stopping-condition count from 31 to 33, so the suite's THE MERGED-NAME CASE: a branch whose old PR merged binds the OPEN one (CLOUD-465) case is still present and still named that, but any line number cited against it is stale. Work by case name.

CLOUD-464 `a silent bot with main unmoved keeps polling` asserts how fast land services SIGTERM, not that it kept polling — red under load, green alone

Why

CLOUD-426 fixed one half of this pair, and its §2 named the rest of the work: "Any other test asserting an outcome via a real fork race has the same defect; a sweep for the shape belongs with this fix." This is that shape, found — in the sibling case, by a different mechanism.

tests/land.bats:938 runs timeout -k 1 5 "$LAND" and asserts [ "$rc" -eq 124 ].

The property under test is "land was still polling at 5s" — that a silent bot with main unmoved does not end the lap. 124 is not that property. GNU timeout returns 124 when the command dies from the TERM it sent, and 137 when -k had to escalate to KILL because TERM was not serviced in time. land runs set -m, installs an EXIT trap and reaps two watcher process groups, so how long it takes to die is a function of machine load — and the window is one second.

Observed 2026-08-12 inside mise run verify on the CLOUD-420 branch, with four subagents contending for the box:

not ok 539 a silent bot with main unmoved keeps polling
# (in test file tests/land.bats, line 938)
#   `[ "$rc" -eq 124 ]' failed
# tests/land.bats: line 924: 23832 Killed   timeout -k 1 5 "$LAND" > "$out" 2>&1

Re-run in isolation immediately afterwards: 5 of 5 pass. The same failure economics CLOUD-426 documents — verify goes red, land stops with "Reproduce and fix locally; CI is not where you discover this", and the finding reproduces nowhere.

Root cause. Both 124 and 137 mean the same thing here: the timeout fired, so the process was still running. A land that ended the lap on its own exits with its own status, and neither code can appear. The assertion discriminates on the one axis the case is not about, and that axis is load-sensitive.

Refinement — Ready

• Source of truth (§1). Whether land was still polling when the clock ran out — not how promptly it serviced the signal that stopped it.
• Mechanism (§3). Assert that the timeout fired: 124 (died on TERM) or 137 (needed the -k escalation). Both are timeout reporting "the command did not finish"; only the second is also a statement about scheduling.
• Deliberately not in scope (§2). Retries, sleeps, bats --retry, or a longer -k grace. A longer grace widens the window without making it load-independent — the same defect with a better success rate. Also out of scope: land's signal handling, which is not wrong.
• Not a loosening (§2). Discriminating power is unchanged: a land that stops polling exits with its own status and produces neither code. This is the distinction CLOUD-426 §2 draws when it refuses "2 or more comments" — that widening admitted outcomes the mechanism itself could produce; this one does not.

Test obligation

Mutation-checked per CLOUD-418: with the poll broken so land ends the lap instead of waiting, the case must still fail. Verified under contention rather than in isolation — running it green alone is precisely the evidence that misleads.

Commit / bump (§6): test(land) — no bump. Corrected 2026-08-21 (CLOUD-595): the block said "patch until 0.1.0 regardless of type", and "regardless of type" is the half that is wrong. Below 0.1.0 every release-worthy type collapses to a patch, but test is not one — a test-only change releases nothing at any version, so demanding a patch promises a bump release-plz never produces.

Blockers (§8): none.

Acceptance

• The case's verdict is independent of machine load, shown by running it under contention.
• A land that stops polling still fails it.
• No retry, sleep, or widened grace period is introduced.

Skipped by bundle A of CLOUD-926 — claim-check refuses it assigned (2026-08-23)

This row is in bundle A's chain and was not worked. mise run claim-check, with this row's own get_issue payload on stdin:

CLOUD-464 assigned
::error:: claim-check: not pullable — someone is already on it.

The row is Todo with assignee: alec@button.is, so the assigned rule fires.

Not worked around. BATTEN_CLAIM_TAKEOVER=1 would have minted the receipt, and it was not used: that flag answers "the competitor is this branch", and here it is not — there is no branch of mine to resume and no board move of mine to undo. mem:workflow/board-states is explicit that a takeover is for a branch, not for a doubt, and that assigned's deliberate ambiguity (every agent authenticates as the same tracker user, so it cannot say "assigned to someone else") is a reason to read the row as occupied rather than to discount it. CLOUD-430 is what discounting it costs: a full duplicate implementation, built and discarded, after an override argued from three signals that are all blind during exactly the window a claim exists to cover.

The rest of bundle A landed on claude/ci-performance-degradation-rplznx (PR #651): CLOUD-674, CLOUD-827, CLOUD-904, CLOUD-903, CLOUD-727.

One thing worth flagging to whoever holds this row, because bundle A moved the line it points at. tests/land.bats:938 is no longer that line — the suite gained three cases in this bundle (the CLOUD-904 pair and the CLOUD-827 stop) and land.sh's stop count went 31 → 33. The case is still named a silent bot with main unmoved keeps polling and the timeout -k 1 5 / [ "$rc" -eq 124 ] shape is untouched, so the finding stands exactly as written; only the line number in §"Why" is stale. Fix by case name rather than by line.

CLOUD-944 `mutant` run concurrently with another suite reports false survivors and false case-already-red, so a contended reading looks exactly like a coverage defect

Why

mise run mutant gives wrong answers when another suite run is in flight, and the wrong answers are indistinguishable from the real defects it exists to find.

Measured 2026-08-23, one session, three readings of the same tree:

run	concurrent with	reported
A	mise run test:bats and a second mutant	land-lock/stall-never-bails case-already-red, land-lock/stalled-lease-unstealable SURVIVED
B	a second mutant	cites-read-from-the-argument inert-mutation (real — a stale pattern)
C	nothing	149 declarations across 55 gates, every one caught, exit 0

Run A's two land-lock findings do not reproduce. Nothing in that session's diff touched land-lock — it is another bundle's file domain in the current fan-out — and run C over the same tree is clean.

Why it happens, from the source rather than inferred. The task stages the tracked tree into a mktemp -d workspace once, then per declaration copies the subject in, mutates it, and runs the named case with --filter from inside that workspace. Two things make that contended:

• the per-declaration copy reads the working tree deliberately, "because the moment this matters most is while a gate and its suite are being written" — its own header says so. A concurrent editor, or a second run that is mid-mutation, is therefore a live input.
• the staged workspace symlinks the bats submodule back to the real checkout, and the suites underneath it write into target/ and the receipt store under $GIT_DIR, which are shared with every other runner.

So a case can be red for a reason that has nothing to do with the mutation, and the tool correctly reports what it saw — case-already-red is the anti-vacuity term working, and SURVIVED follows when a contended case passes under mutation for an unrelated reason.

Why this deserves a mechanism rather than a habit. The three verdicts it publishes — SURVIVED, case-already-red, inert-mutation — are all findings about coverage, and a contended run mints them for free. A reader cannot tell one from a real one, and the cost is asymmetric: a false SURVIVED sends someone to fix a declaration that is already correct, and in the measured session it very nearly went onto another bundle's PR as a real defect. Same class as CLOUD-412 (flaky under a full parallel verify) and CLOUD-717 (two concurrent cargo test runs wiping each other's fixtures), one layer up — the tool is honest and its input was contended.

Candidates, stated rather than decided

1. Refuse to start when another run holds the tree. The landing lease's directory-lock helper is the prior art here and is already a task: a lock around the staged-workspace build and the per-declaration loop, released on exit, reclaimed when the holder is dead. Cheapest, and it turns a wrong answer into a wait.
2. Report contention rather than preventing it. A declaration whose clean run is red already records case-already-red; the gap is that it cannot say why. Naming the concurrent runner would make the reading self-describing without serialising anything.
3. Isolate the shared state — its own build directory and its own receipt store. The only candidate that makes concurrent runs correct rather than refused, at the cost of a cold build per run, which likely dominates.

(1) is the smallest change that removes the wrong answer.

Not in scope. The stale-declaration class — that is CLOUD-941, and the two are independent: 941 is a real finding a serial run reproduces, this row is a false finding a contended run invents.

Found while verifying two mutation declarations for CLOUD-829 in bundle B of CLOUD-926, by running the task three times and noticing the answers disagreed.

---

A THIRD mechanism, and it invalidates run C's baseline (2026-08-23, bundle A)

Run C above — "149 declarations across 55 gates, every one caught, exit 0" — was not a complete reading, and the reason is neither contention nor a stale pattern. It is a plain stdin bug, fixed on bundle A's branch (PR #651, commit 79e5393).

The row loop is fed by done <<<"$rows", so the rows sit on the shell's stdin — and bats, invoked inside the loop body, READS stdin and swallowed every row after the one it was running.

Measured on claimed-keys, serially, with nothing else in flight:

declarations in the file	declared counter reached	never applied
3	2	claimed-keys-adopts-speculated

The task printed every one caught and exited 0 over a set it had not finished. Instrumenting the loop confirmed it stops after row 2. Two </dev/null redirects on the clean and mutated bats invocations fix it; the same gate pair then reports 4 declared where it had reported 3.

Why this matters to this row specifically: the tail of every multi-row declaration in the enforced set was unverified, so run C's 149 is a floor rather than a count, and its exit 0 was over a subset. Whatever the concurrency remedy turns out to be, the baseline it is measured against needs re-taking on a tree carrying the fix.

It is a fourth failure shape, distinct from the three named above. SURVIVED, case-already-red and inert-mutation are all verdicts the tool PRINTS. This one printed nothing at all — the row simply never ran, and a skipped row is invisible in output that only reports failures. That is the same asymmetry this row already names, one level further down: a contended run mints false findings, and this minted false silence.

A fifth, worth naming because it costs a round and reads as a coverage defect: running ./mise-tasks/mutant.sh directly rather than through mise gives case-already-red on every case of any gate whose suite needs mise.toml's [env] — the staged bats inherits no CI_REQUIRED_CHECKS, so land's whole suite refuses before any assertion runs. Indistinguishable from a real already-red case. mise exec -- bash -c 'MUTANT_GATES=<gate> ./mise-tasks/mutant.sh' is the form that scopes the set without leaving the environment.

Related, and also fixed on that branch: mutant's header predicts names-no-case as the symptom of an untracked suite. For a NEW gate whose suite is also new the real symptom is case-already-red — the staging is git ls-files, so cp puts the gate in place while the suite is absent, and every case reads as red-before-mutation. That points a reader at their assertions when the fix is git add.

CLOUD-941 Two enforced gates carry a mutation that SURVIVES, and `ready-lint`'s is a no-op: its pattern spells `[ ]` where the code has `[[ ]]`, so the conjunct is covered by nothing

Why

mise run mutant reports two survivors on origin/main 170c7c4 (v0.0.106), on an unmodified tree and under any scoping argument:

ready-lint/replay-demanded-of-a-warn-gate SURVIVED (a block declaring warn is not gated)
board-write-record/overlap-frozen-at-write-time SURVIVED (A FILE THIS BRANCH HAS NOT TOUCHED IS STILL RECORDED)

Both gates are named in $MUTANT_GATES (mise.toml [env]), so they are inside the enforced set rather than CLOUD-480's filed gaps — the tool is reporting, and nothing is reading it.

Found while running mise run mutant ntia-check for CLOUD-666 (bundle C of CLOUD-926). Pre-existing and unrelated to that diff — it reproduces on an unmodified tree — and filed rather than fixed because mise-tasks/ready-lint.sh and mise-tasks/board-write-record.sh are another bundle's file domain in the current fan-out, where two sessions editing one file is the rebase conflict mem:workflow/agent-fanout partitions by file domain to avoid.

The ready-lint one is diagnosed, and it is a one-token mismatch.

mise-tasks/ready-lint.sh:442 declares:

#MUTANT replay-demanded-of-a-warn-gate|s@\[ "\$declares_deny" = 1 \]@true@|a block declaring warn is not gated

The code it means to corrupt is mise-tasks/ready-lint.sh:465:

if [[ "$introduces_gate" = 1 ]] && [[ "$declares_deny" = 1 ]]; then

The pattern spells a single-bracket test (\[ … \]); the source is a double-bracket conditional ([[ … ]]). The sed expression therefore matches nothing, the "mutated" copy is byte-identical to the original, tests/ready-lint.bats:872 passes as it always does, and mutant correctly reports a survivor. Most likely the conditional was normalised to [[ ]] at some point and the declaration was not carried along.

What that leaves uncovered. The declares_deny conjunct is what keeps deny-without-replay off warn gates — CLOUD-751's scoping decision, and the reason tests/ready-lint.bats:872 exists at all. That case is currently proven to pass on the working code and never shown to fail on the broken code, which is precisely the "test that cannot discriminate" class CLOUD-418 built this tool to find. The conjunct is not broken; the proof that it is load-bearing is.

The board-write-record one is NOT diagnosed here. It is recorded because it reproduces in the same run and belongs to the same class, and stating it without having read the gate would be the overclaim this repo keeps paying for. Whoever takes this row should treat it as a second instance to be diagnosed on its own terms, not as a copy of the first.

Not a mutant defect. The tool gave the honest verdict. Compare the two failure modes it does name and distinguish — unappliable-mutation when sed errors, and names-no-case when field 3 matches no test — both of which CLOUD-666's own two new declarations hit and had to fix before landing. A silent no-op substitution is the third shape, and the only one whose output reads as coverage: sed does not consider "matched zero lines" an error, so an unappliable-in-effect pattern applies cleanly.

What lands

• ready-lint's pattern matches the code, so the mutation kills tests/ready-lint.bats:872.
• board-write-record's survivor is diagnosed and either killed or reclassified.
• mise run mutant reports no survivor for either id.

Refinement — Ready (2026-08-23)

• Source of truth (§1). Each gate's #MUTANT line is its declaration; mise-tasks/mutant.sh is the authority on how one is applied and judged; the named case in the gate's own suite is what it must kill. $MUTANT_GATES in mise.toml [env] is the authority on which gates are enforced, and it already names both.
• Predicate (§2). mise run mutant prints no SURVIVED line for replay-demanded-of-a-warn-gate or overlap-frozen-at-write-time, and exits 0. A command and an exit code over the tree; nothing is judged.
• Effect (§3). For ready-lint, unchanged: it edits one comment line — a mutation declaration — and no code path, no subprocess, no file, no network call, so ready-lint's verdict on every payload is byte-identical before and after. For board-write-record the effect cannot be stated before the diagnosis, and this clause must be re-read once it is.
• Output and exit (§5). Unchanged and pointer-only: mutant's output is already the gate, the mutant id and the case, never a diff of mutated source.
• Commit / bump (§6). fix(gate) → patch; the workspace is 0.0.106, below 0.1.0, where every release-worthy type collapses to a patch. It touches nothing under crates/, so release-plz cuts no release for it on its own — it reaches a tag by being swept up, which is the ordinary case for task-layer work.
• Test obligation (§7). The §2 predicate is the test, and that is the point rather than a shortcut: the deliverable of this row is a mutation that kills a case, so "the mutation kills its case" is the assertion, already a runnable command with an exit code. Two things worth asserting past it:
  • The corrected pattern kills the named case specifically, not merely some case — a pattern broad enough to break the whole suite would also report clean, and would be a worse declaration than the one it replaced.
  • A scan for the same mismatch across every #MUTANT declaration in the tree. This is the durable half, and the reason this row is worth more than a typo fix: one stale pattern is an accident, and the same accident is silently available to all ~40-odd declarations, each of which reads as coverage while asserting nothing. The mechanism is a refusal when a declaration's sed expression matches zero lines of its own subject — the third verdict mutant does not currently have. That is arguably its own row and is named here rather than assumed into this one's scope; if it is split out, that row carries the deny-without-replay obligation.
  • Replay (§7) is not demanded of this row: it introduces no gate and changes no severity.
• Blockers (§8). None. relatedTo CLOUD-418 (the discriminate-or-it-is-not-coverage class both instances belong to), CLOUD-480 (the enforced-set expansion that brought these gates under mutant) and CLOUD-751 (the deny-only scoping the ready-lint conjunct implements).

Pointers. mise-tasks/ready-lint.sh:442 (the declaration) and :465 (the conditional it misses); tests/ready-lint.bats:872 (the case that must go red); mise-tasks/board-write-record.sh and its overlap-frozen-at-write-time declaration (undiagnosed); mise-tasks/mutant.sh (the verdicts it distinguishes, and why a no-op substitution is not among them); $MUTANT_GATES in mise.toml.

Correction from bundle A (2026-08-23): the "third verdict" §7 asks for ALREADY EXISTS

§7's durable half proposes "a refusal when a declaration's sed expression matches zero lines of its own subject — the third verdict mutant does not currently have", and the Why section argues a silent no-op substitution is a shape the tool cannot name because "sed does not consider 'matched zero lines' an error, so an unappliable-in-effect pattern applies cleanly."

That verdict is inert-mutation, and it is already implemented — mise-tasks/mutant.sh compares the staged copy against the original after applying the script and reports inert-mutation when they are byte-identical, which is exactly the zero-match case. The Why section's own table cites run B hitting cites-read-from-the-argument inert-mutation for a stale pattern, so the mechanism is observed working in this row's own evidence.

I hit it directly while landing CLOUD-674: moving a conditional inside a new else branch left claimed-keys-closing-only-falls-through's un-indented pattern matching nothing, and mutant reported inert-mutation rather than a survivor. Re-anchoring the pattern with the leading tab fixed it.

So the scan §7 wants is a one-line invocation, not a new mechanism: mutant over every gate already refuses each stale declaration by name. What is worth keeping from that clause is the sweep — running it across all ~55 gates so every stale declaration is found at once rather than as each is stumbled on.

Which leaves this row's own ready-lint diagnosis needing a second look. If the pattern truly matched zero lines, the verdict would have been inert-mutation, not SURVIVED — they are different branches of the same loop. Either the pattern matches something else and changes the file without disarming the conjunct, or the SURVIVED reading came from one of the two contended/incomplete readings now recorded on CLOUD-944. Worth re-running serially, through mise, on a tree carrying CLOUD-944's stdin fix before acting on the [ ] vs [[ ]] explanation.

Not touched here: mise-tasks/ready-lint.sh and board-write-record.sh are bundle B's file domain, and this row is claimed. Recorded rather than fixed.

📝 Walkthrough

Walkthrough

The land task now reports lap-cap cost and failure causes, handles speculative-tree verification failures, and applies closing-key and prose-only stopping conditions. The claimed-keys command adds --refs-first-only. The closing-key check validates every served key and supports keyed or global DO-NOT-CLOSE exemptions. The landed check accepts --landed-by evidence. Mutation execution and benchmark reporting were updated.

Merge Risk: 🟡 Moderate · up to faac2

The PR changes landing validation, but the current head can still treat inline Refs: prose as served work and reject valid closing PRs, while pure renames may also be refused incorrectly. These are bounded correctness risks, but the extractor issue should be fixed or explicitly accepted before merging.

Review — the diagnosis holds, the remedy regresses behaviour

What is right, and should survive whatever happens to the diff. "A cap is a checkpoint, not a stop sign" is correct, and the scope discipline is the strongest part of this PR: measuring the text predicate over the class (103 of 420 name a runnable object → fires on 75%), ruling it unshippable against CLOUD-751's own criterion, recording that regorus here carries no regex builtins (CLOUD-885), and routing the general property to the structural fix-XOR-no_fix_reason invariant instead of inventing a prose heuristic. That reasoning is worth keeping on CLOUD-871 regardless of this diff's fate.

Blocking concern. The new message removes a CI spend brake. charge_wait refunds every lap that bought no CI, so reaching LAND_MAX_LAPS means two charged matrices already went unlanded — and the remedy now says re-run unconditionally, which buys two more with nothing changed. It also names a check that gates nothing, inverts the posture of the sibling LAND_EXIT_FLEET_SATURATED refusal, and leaves in place the diagnosis this file records CLOUD-413 measuring wrong twice over across 24 laps. Detail and a suggested rewrite are inline on the message.

Rebase, before anything else. main has moved twice through these exact lines:

• 7e7a3b6 refactor(tasks)!: name a shell program .sh renamed mise-tasks/land → mise-tasks/land.sh. Both hunks and the #MUTANT row target a path that no longer exists — hence mergeable_state: dirty; this is a rename/modify conflict, not a content one.
• d6a4dfd refactor(tasks): require [[ over [ rewrote the lap-cap guard to [[ ... ]] (now land.sh:1175) and re-aimed the #MUTANT block this adds a row to.

(The new bats case's [ "$status" -eq 5 ] is fine — that codemod covered mise-tasks/ and tests/helpers.bash only; .bats is CLOUD-382's half and tests/land.bats still carries 263 single-bracket tests on main.)

Process note, not a code finding. CLOUD-871 went back to Todo at 05:17Z and is now blockedBy CLOUD-886 — which was filed at 05:08Z because of this PR: correcting one sentence under mise-tasks/ ran all 151 suites, 1,188s serial, where subject-based selection would have run tests/land.bats for 141.5s. Landing this before CLOUD-886 pays that bill again on every lap, and the branch is currently unclaimed against its own row.

Two smaller findings inline: the #MUTANT is tautological against an assertion that hardcodes its literal (CLOUD-418's own failure shape), and ~37 of the 51 added lines are a third, fourth and fifth copy of reasoning that already lives on CLOUD-871 and in the PR body.

Summary: rebase onto land.sh, keep the intent, change the imperative so it names the cheap continuing action instead of re-arming the spend, reconcile with the sibling exit, tighten the assertion and the mutant, and cut the prose to a pointer.

RUN THIS AGAIN un-caps a CI spend brake, and the sentence it is appended to is one this file already refutes. Four points, all on this one string.

1. Reaching this cap does not mean cheap laps — it means two matrices already spent. charge_wait (land.sh:383, and again at the lease branch ~:1466-1473) decrements lap on every path that bought no CI:

Both must refund the lap — a busy fleet would otherwise exhaust LAND_MAX_LAPS on waiting alone and give up without ever having attempted

So a lap only counts when it actually spent a matrix. LAND_MAX_LAPS=2 therefore fires after two charged CI matrices that did not land. An unconditional "RUN THIS AGAIN" buys two more with nothing about the branch or main changed. This is the one exit path whose job is to stop precisely that, and the remedy now instructs the caller to defeat it — against the workflow contract's "a CI run costs real minutes".

2. The named check gates nothing. git log --oneline --since=30.minutes origin/main | wc -l yields a number, and the sentence supplies no threshold and no branch on the result — you are told to run again either way. That satisfies CLOUD-871 §2's "names a runnable object" while deciding nothing, on the row that argues this distinction is the whole point. Non-negotiable rule 3 is the same shape: a gate resolves to a command and an exit code over an object it decides.

3. It inverts the two exhaustion paths. LAND_EXIT_FLEET_SATURATED (land.sh:388) is the sibling refusal on the path that spent nothing, and it says "The fleet is saturated: wait, or land later." After this change the no-spend path says stop and the two-matrices path says go. Whichever posture is right, that pairing is backwards, and CLOUD-399's "the two exhaustions are told apart by CODE" argues they should be told apart by their remedies too. This PR does not touch or mention the sibling.

4. The retained clause is the diagnosis this file records as measured-wrong. land.sh:391-396:

charging it to the lap budget would let a rate-limited bot exhaust the budget that exists to catch "main moves faster than a lap takes" — and would report that diagnosis, which is what CLOUD-413 measured being wrong twice over across 24 laps

"main is moving faster than a lap takes" survives here unchanged, and the fix appends an imperative to it.

Suggested direction. Name the cheap continuing action — rebasing is what stops the branch ageing; re-running land is what buys CI — and let the caller see the cost they are re-committing:

still not linear after $max_laps charged laps: two CI matrices went unlanded. Rebase now so the branch does not age (git fetch origin main && git rebase origin/main), then re-run mise run land — lapping is how a branch catches up, and stopping is how it stops being landable.

Continuing is still named and still unambiguous; the ageing concern is addressed by the action that actually addresses it; and the spend is stated rather than silently re-armed. Reconciling the posture with LAND_EXIT_FLEET_SATURATED in the same commit would close point 3.

This mutation is tautological — it proves the assertion is wired, not that it discriminates. The case asserts [[ "$output" == *"RUN THIS AGAIN"* ]], and the mutation is s/RUN THIS AGAIN/look/. The assertion hardcodes the exact literal the mutation removes, so it cannot fail to catch it, and it would equally "catch" any rewording of a message that was still perfectly good.

That is the shape CLOUD-418 exists to refuse: "a test that cannot discriminate ships as coverage." The mutant count going 135 → 136 reads as coverage improving while nothing new is actually being discriminated.

A mutation with teeth would break the property rather than the string — e.g. remove the runnable command from the remedy while leaving the imperative intact, or swap the imperative to a stopping one while leaving the command intact. Those are the two halves the case's own comment says both have to hold; today only the second is probed, and only by identity.

[wenzowski]

Agreeing with CodeRabbit here, for a reason worth stating: *"git log"* matches the two-word prefix of any git log invocation, so the remedy could degrade to a command that does not answer the question — a truncated one, one that lost origin/main, one whose window changed — and this stays green.

The case's own comment says the clause that rots is the one about naming a runnable check. A substring that stops at git log does not assert runnable; it asserts that the words appear. Assert the whole command as emitted.

While you are here: the assertion below it, *"RUN THIS AGAIN"*, is what makes the #MUTANT on land:94 tautological — see that comment.

29 lines of comment on a 9-line case, and every argument in it is already written down twice. The 103-of-420 measurement, the 75% firing rate, the regorus-regex point, the no_fix_reason/findings.rs structural argument and the 55-minute anecdote are on CLOUD-871 and in this PR's body. This is the third and fourth copy.

AGENTS.md's output posture names exactly this: a finding's home is an issue or a memory, and "once there, restating it here is a copy with no reader" — with the added cost that a copy in the tree drifts. If any of these numbers is re-measured, four places now disagree.

Two lines pointing at CLOUD-871 would carry the same information with one authority. What genuinely belongs in the file is the DELIBERATELY-SINGULAR instruction, because that one is addressed to whoever opens this file next and has nowhere else to live.

Same applies to the 8-line block above the die_with in mise-tasks/land — a fifth copy of the same paragraph.

Filed the blocking finding from my review as CLOUD-904 so it has a durable home independent of this PR — both defects survive whatever text lands here.

It carries the two facts that decide what the corrected message should say:

1. charge_wait refunds every lap that bought no CI, so reaching LAND_MAX_LAPS means max_laps matrices were spent and unlanded — not that main outran a lap. The retained "main is moving faster than a lap takes" clause is the diagnosis land.sh:391-396 records CLOUD-413 measuring wrong twice over across 24 laps.
2. The unspent exit (LAND_EXIT_FLEET_SATURATED) says wait; the two-matrices exit is the one being changed to say go. CLOUD-399 separated them by code and never reconciled their remedies.

This row is relatedTo CLOUD-871, not a replacement for it: CLOUD-871 still owns the remedy-text class and this PR is still its worked instance. CLOUD-904 just owns what the instance should say. Its acceptance is written so the corrected text lands here rather than on a separate branch.

Restrict extraction to Refs: records.

Line 199 matches Refs: at any position. A commit message can contain Cites Refs: CLOUD-999 in prose and a real Refs: CLOUD-661 record. This function returns both keys.

closing-key-check.sh then treats CLOUD-999 as served and rejects a body that correctly closes only CLOUD-661. Anchor the pattern at the start of the line. Add regressions for both claimed-keys and closing-key-check.

This loop only classifies hunk lines. If Git detects a pure rename, copy, mode change, or binary change, it can emit no + or - content lines. prose_only then remains 1, so the task refuses a diff that is not “whole diff is comment lines.”

Track whether the diff contains any content lines. If it does not, classify the change as not prose-only. Add a pure-rename regression test with rename detection enabled.

--refs-first-only to recognize Refs: only at the start of a trailer line,
matching the documented boundary and excluding inline text such as Cites Refs:.
Add regressions covering both extracted keys and closing-key-check behavior,
while preserving valid trailer extraction.

- Around line 1538-1540: Update prose-only-check so diffs containing only file
renames, with no added or removed content lines, return success instead of being
classified as prose-only; preserve existing behavior for actual prose-only
changes. Add a regression test covering a pure rename and its successful result.

Align the extractor with the documented Refs: trailer boundary.

claimed-keys --refs-first-only is documented as authoritative for trailers, but the current extractor still matches Refs: anywhere in a commit message. For example, Cites Refs: CLOUD-999 can become a served key and make closing-key-check process a citation as served work. Anchor extraction to the start of the trailer line and add regressions for key extraction and closing-key checks.

Admit pure renames before this refusal.

A pure rename has no changed content lines. mise-tasks/prose-only-check.sh keeps prose_only=1 and exits 2 for that diff. Line 1539 then blocks a non-prose change and requires a false override record.

Make prose-only-check return success when the diff has no content hunks. Add a pure-rename regression test.
