ci(gate): the ready-lint chain — a §6 break claim names its surface, the corpus catches up, §7 is checked against the tree and against a replay

[wenzowski]

The ready-lint chain: four rows against one gate, one branch, because 842 and
751 both edit the §6/§7 region of mise-tasks/ready-lint and the same
tests/ready-lint.bats. Splitting is a guaranteed conflict for zero parallelism.

Builds on CLOUD-852 (b405ca8, #625), which made "Not !" parse correctly by
reading the break marker off the type token rather than off the whole line.
Refusing an unqualified denial on top of a misparse would have been wrong, which
is why that went first.

What each row closes

Closes CLOUD-842 — batten is both a binary and a library, so "breaking"
names two objects and §6 has one word for them. Five rows declared "not !",
every one reasoning correctly about the CONSUMER surface, and the change landed
as 1f9b41c2 feat(policy)! because cargo-semver-checks measures the other one.
ready-lint now refuses a negative-breakage claim that names neither surface.
The qualifier must ATTACH to the denial rather than merely share the line —
CLOUD-832's clause carries the word consumer forty characters downstream, so a
"does consumer appear anywhere" predicate passes the one row the clause exists
to refuse. The five landed rows are corrected as a record in the same change.

Closes CLOUD-595 — the Todo queue's Ready blocks, swept against the gate as
it stands after this branch. graph-check's todo-not-ready refuses the whole
board on any ready-lint exit 1, so a corpus left behind by a gate change is not
a cosmetic debt; it is the board unusable. Measured: 73 payloads, 5 refusals
before, 3 after — and every repair a mechanical §6 or §7 edit that moves no scope.

Closes CLOUD-826 — ready-cites-check, a new gate beside ready-lint and
deliberately not inside it: ready-lint is called by path from
board-write-record's hook, where the cwd is the tool call's, so teaching it to
read files would make its verdict depend on where a hook fired.

Closes CLOUD-751 — a deny gate must report a measured firing rate before a
severity is chosen. CLOUD-514 set that standard at 99.5% false positives and then
shipped filed-here-check without one of its own. Replayed over the corpus this
branch already fetched: 73 payloads, 1 firing, 0 false positives.

Verification

Recorded per commit in the messages. mise run test:bats, mise run mutant over
every declared mutation, mise run verify.

One row filed from this branch, and why it is not a punt

CLOUD-858 was filed from this branch and names mise-tasks/ready-lint, a file
this diff changes, so filed-here-check's proximity half sees it. It is
independent work rather than a deferral of this one: it covers three Todo rows
(CLOUD-472, CLOUD-275, CLOUD-134) whose repair means WRITING a Ready block or
moving a column — refinement whose content belongs to those rows, and explicitly
outside CLOUD-595's scope, which states that no issue's §1–§5, §7 or §8 content is
an input to or an output of the sweep. Narrowing a sibling row's scope to fit is
the shape this repository refuses; so is acquiring a Ready block that papers over
open questions, which is what CLOUD-472 would need. It stays open and is not
closed here.

[linear-code]

CLOUD-842 A §6 clause can assert "not `!`" about a crate that is also a library, and `ready-lint` cannot check it — five rows declared it and a `feat(policy)!` landed

Why

Five rows in the CLOUD-839 bundle each declared, in §6, that their change was not breaking. Measured on main at 12cca46: the change landed as 1f9b41c2 feat(policy)!: analyse a composed rule set as a whole — a declared breaking change.

The rows: CLOUD-832, CLOUD-833, CLOUD-836, CLOUD-837, CLOUD-647. Every one of them still carries the wrong clause.

And every one of them was reasoning correctly, which is the finding. Their §6 clauses said things like "Not !: the string deny path is preserved, so no consumer shape breaks" and "widening scopes is additive; no existing pairing is removed". All of that is true. 1f9b41c2's own body states why it did not survive:

The rows' §6 clauses each say "not !", and every one of them is reasoning about the CONSUMER-FACING shape: no batten.toml breaks, the bare-string deny path is preserved, and widening scopes removes no pairing. All of that is true and none of it is what cargo-semver-checks measures. The Rust API does break, the crate is a library as well as a binary, and the gate decides.

batten is both a binary and a library, so "breaking" names two different objects, and §6 has one word for them. A row can be entirely right about the one a consumer sees and entirely wrong about the one mise run semver measures.

Why ready-lint cannot catch it, and why that is the actual gap

ready-lint's §6 arrows (CLOUD-228, CLOUD-290) derive an expected bump from the declared conventional-commit type and compare it against the declared bump. That is a check over two strings in one line, and it is correct as far as it goes.

It cannot check "not !", because that is a claim about a diff that does not exist yet. cargo-semver-checks decides it at implementation time by comparing two compiled APIs. At refinement time there is nothing to compare, so the clause is unfalsifiable when written and refuted only after the work is done — which is exactly when re-deciding it is most expensive, and, here, five rows late.

So this is not "make ready-lint predict semver". The predicate has to be about the claim's shape, not its truth.

Minimal capability

ready-lint refuses a §6 clause that asserts a negative about breakage — not !, not breaking, no break — unless it names which surface it means. The two surfaces are already distinct in this repo and already have gates:

• the consumer surface — batten.toml rows, exit codes, output shape — gated by derived-check, schema-check and the CLI suites;
• the library surface — the pub Rust API — gated by mise run semver.

A row may claim either. A row claiming "not !" unqualified is claiming both, and it cannot have checked the second. The refusal names the two spellings that are checkable and points at semver as the thing that decides the library half.

What must NOT happen is the clause being dropped. §6 exists so a row states its release consequence; the fix is that it states which surface it is about, not that it stops saying anything.

Refinement — Ready

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

• Source of truth (§1). mise-tasks/ready-lint's §6 block — the same place CLOUD-228 and CLOUD-290 corrected the arrows. No second list of surfaces: the two named above are the ones the existing gates already divide the tree into, and this row adds no third.
• Computable predicate (§2). Over the §6 line, after the existing type/bump extraction: a negative-breakage assertion that names neither surface is reported at exit 1 as unqualified-break-claim. Decidable from the body alone — no diff, no build, no network, which is the whole reason it is a claim-shape check rather than a semver prediction.
• Effect (§3). read. A mise-tasks/ gate over stdin; no verb, no SURFACE row, no movement in the derived allowlist.
• Generated artifacts (§4). None.
• Output & exit (§5). Pointer-only per non-negotiable rule 4: the issue id, the line number, and the rule id — never the clause's prose. Joins the existing exit-1 vocabulary beside bump-disagrees-with-type rather than inventing a channel.
• Commit / bump (§6). ci — no bump. A mise-tasks/ gate, not the crate; release-plz releases nothing for it at any version. (Stated with the surface named, per this row's own rule: no library API is touched, and no consumer surface either.)
• Test obligation (§7). Fixture-driven bats cases. Shown able to fail (CLOUD-418):
  • (a) an unqualified not ! → exit 1, unqualified-break-claim; red today: silent.
  • (b) the same clause qualified as consumer-facing → passes.
  • (c) the same clause qualified as library API → passes.
  • (d) a §6 line making no breakage claim at all → untouched, so this does not become a demand that every row discuss semver.
  • (e) the corpus case: CLOUD-832's §6 as it was written must trip (a). That is the instance this row exists for, and a fixture that cannot reproduce it is not evidence.
  • A MUTANT directive: demoting the refusal to a note must be a mutation the suite catches.
• Blockers (§8). None. relatedTo CLOUD-228 and CLOUD-290 (the §6 arrows this extends), CLOUD-102 (the cargo-semver-checks gate that decides the library half), CLOUD-595 (the corpus left behind by CLOUD-228's fix, the same shape one level up), CLOUD-418 (shown-able-to-fail), and CLOUD-832 / 833 / 836 / 837 / 647 (the five instances).

Acceptance

• An unqualified negative-breakage claim in §6 is refused, naming the two surfaces.
• A qualified claim of either kind passes.
• A §6 line that makes no such claim is unaffected.
• CLOUD-832's original §6 text reproduces the refusal in a fixture.
• The five landed rows are corrected in the same change — each §6 clause re-stated as consumer-facing, with the landed feat(policy)! noted. They are In Review, so this is a record correction rather than a re-scope, and leaving them is a board lie about what a reader should expect from the next release.

Found while auditing what the CLOUD-839 fleet landed — by checking the rows' acceptance against the tree rather than against their commit messages.

CLOUD-595 CLOUD-228 fixed the §6 gate and left the corpus behind, so refined Phase 3 issues now refuse their own pull

Why

The Definition of Ready §6 was amended on 2026-08-07: below 0.1.0 the SemVer arrows do not fire, so a block must declare the bump as "patch until 0.1.0", and the clause names the anti-pattern outright — promising an arrow the tooling will not produce. CLOUD-228 brought ready-lint into agreement with that clause (PR #156, Done 2026-08-13) and its own body records the state of the corpus at the time: "mise run ready-lint on the corpus's most thoroughly refined issue passes today only because that issue carries the retired arrow."

That observation was never turned into work. The gate now enforces the amended clause; the Ready blocks written before the amendment still assert feat → minor. The two artifacts agreed before CLOUD-228 and disagree after it, in the direction that refuses honest work: a block written to the old table now refuses its own pull.

The refusal only became reachable when CLOUD-431 put ready-lint on claim-check's path, which is why this went unnoticed for a day — before that, nothing linted a block at the moment of pulling it.

Measured 2026-08-14 while draining the Phase 3 bundle (CLOUD-82 → CLOUD-166 → CLOUD-165):

• CLOUD-165 — refused at pull time: not-ready (ready-lint refuses this block), from bump-disagrees-with-type (feat implies patch below 0.1.0). Corrected in place, and that correction cost the pull: claim-check's refined-this-session predicate then refused the same session, correctly, so the issue is Ready and unimplemented in the Todo queue.
• CLOUD-82, CLOUD-166 — carried the identical retired arrow and landed anyway (PRs feat(drain)!: bound the advisory payload by a per-rule cap and a token budget #438, feat(drain)!: answer an unchanged cycle with a marker, and never skip its record #442), because their claim-check runs predated CLOUD-431's ready-lint step. The blocks are stale, not the code.

Why this is one ticket and not each implementer's chore

Fixing a block is what makes it unclaimable by the fixer. claim-check's refined-this-session predicate refuses a pull whose refinement postdates the session start — CLOUD-431 working exactly as designed, since an agent refining a block and then implementing against its own refinement is the laundering path that predicate exists to close. So an implementer who repairs the arrow on the way in has traded a lint failure for a claim failure and still cannot do the work. The sweep has to be a deliberate pass by someone who is not about to implement the swept issues.

Acceptance

• Every Ready block in the Todo queue declares the bump the current regime actually fires; asserted by running ready-lint over the queue's payloads and getting zero bump-disagrees-with-type violations.
• The sweep is a refinement pass only — no block's §1–§5, §7 or §8 content changes, so no issue's scope moves while its arrow is corrected.
• Superseded, and satisfied. This clause asked that a Todo issue asserting a retired arrow be caught for the set rather than one issue at a time. graph-check's todo-not-ready clause already does it (CLOUD-375, Done) — see the scope reduction in the Ready block below.

The third clause is the one that keeps this from recurring. Correcting today's blocks is a one-off; the queue acquiring another stale arrow the next time the regime moves — at 0.1.0, when every corrected block becomes wrong in the other direction — is the same defect with the sign flipped. CLOUD-355 is the adjacent observation about the release scheme itself.

Pointers. The version-aware mapping is mise-tasks/ready-lint (the BUMP_LABEL section, case "$crate_version"); the pull-time caller is mise-tasks/claim-check; the frontier computation that clause 3 would extend is mise-tasks/graph-check. The amended clause is §6 of the Definition of Ready & Done.

---

Refinement — Ready (2026-08-17)

• Source of truth (§1). mise-tasks/ready-lint's BUMP_LABEL section is the one authority for which SemVer arrows fire, and it reads the regime out of Cargo.toml's [workspace.package] version rather than hardcoding a table. The corpus is the Todo column's Ready blocks — 46 issues in the Batten project at 2026-08-17, enumerated by status rather than by a remembered list. No issue's §1–§5, §7 or §8 content is an input to this pass or an output of it.
• Predicate (§2). mise run ready-lint over each Todo issue's payload reports zero bump-disagrees-with-type violations. The set-level form already exists and needs no work: graph-check's todo-not-ready clause runs ready-lint over every piped Todo payload and refuses on it, naming the id.
• Effect (§3). The sweep is tracker content only — a §6 line edited per stale issue, which the board-states memory classifies as content rather than a state transition, so nothing here is a permission-bearing act. It touches no file in the tree, so it has no rule row and no allowlist entry. ready-lint and graph-check are read-only and already classified.
• Output and exit (§5). Pointer-only, unchanged: ready-lint emits <id>:<line> bump-disagrees-with-type (<type> implies <bump> below 0.1.0) and graph-check emits the id and the rule. No issue body text is echoed by either, which is what lets the sweep's verdict be pasted into a log.
• Commit / bump (§6). none → no bump. The pass lands no commit: the corpus is Linear rows and the mechanism it would otherwise need already shipped. Stating that outright rather than inventing a type is the honest declaration under §6's amended clause — the same clause this issue exists to serve.
• Test obligation (§7). No new test, and the reason is the scope reduction below rather than an exemption: the recurrence case already exists in the graph-check suite behind CLOUD-375's todo-refusal-is-a-note mutant, which fails a suite that asserts the string without asserting the exit status. The pass's own verification is the predicate in §2 — graph-check over the swept queue exiting 0 — which is a gate run, not a new case.
• Blockers (§8). None. relatedTo CLOUD-228 (the gate change that stranded the corpus), CLOUD-431 (the refined-this-session predicate that makes this a separate pass), CLOUD-375 (the set-level refusal this leans on) and CLOUD-355 (the adjacent observation about the release scheme).

Scope reduced at refinement (2026-08-17): clause 3 is already built, so this is a sweep and not a mechanism.

The third acceptance clause asked that a stale arrow in the queue be caught for the set rather than one issue at a time. graph-check does that today: todo-not-ready (CLOUD-375, Done) runs ready-lint over every piped Todo payload and reports $id todo-not-ready as a refusal, not a note — the distinction its own todo-refusal-is-a-note mutant exists to hold. A stale §6 arrow makes ready-lint exit 1, which makes todo-not-ready fire, which fails the gate. Nothing needs building for the recurrence half.

What that leaves is the repair, and it is still worth doing rather than dropping: while any queued block asserts a retired arrow, graph-check refuses the whole board, so the set-level gate is unusable until the corpus agrees with it. Non-negotiable rule 2 is satisfied by pointing at the shipped mechanism rather than by adding a second one.

The queue is larger than the incident that prompted this. The body above measures three issues found while draining one bundle. The Todo column holds 46 at 2026-08-17, so the pass is an enumeration over that column and not a visit to the three named issues. Two were spot-checked while writing this block and both are already compliant — CLOUD-461 (`feat` → patch until 0.1.0) and CLOUD-236 (`ci` → no bump) — which bounds nothing about the other 44 and is recorded only so the sweeper does not read "the corpus is stale" as "every block is stale".

Who may run it. Not a session that will then implement any issue it swept: claim-check's refined-this-session predicate refuses a pull whose refinement postdates the session start, so a sweeper who then pulls has traded a lint failure for a claim failure. This is the constraint the body already names, restated here because it is a precondition on the pass rather than a fact about the defect.

CLOUD-826 A Ready block's §7 can demand tests the tree does not carry: CLOUD-740 cites two that CLOUD-780 deleted, its own header calls them historical, and `ready-lint` exits 0

Why

Two gates cross-check a Ready block, and between them they leave the tree out.

• ready-lint decides the block's checkable clauses — the §6 bump against the commit type, the §8 blocker prose against a real blockedBy relation. It is a pure function of the payload and must stay one: board-write-record invokes it from a hook, addressing it by path because "a hook inherits the cwd of the tool call, which is not required to be inside this project". It never looks at a file.
• spec-ref-check decides that a CLOUD-N §M citation in the tree names a clause the issue carries.

So the tree is checked against the issue, and the issue's clauses are checked against each other. Nothing checks the issue against the tree — that a §1/§2/§7 naming a test, a symbol or a file names one that exists.

Measured 2026-08-21 on c78fd8a, and the instance is live

CLOUD-740's Ready block, §7, demands:

(b) a_snapshot_captures_a_dirty_tree_and_nothing_else still holds… (c) the_worktree_listing_reads_gits_own_attributes still holds, over both locked and prunable.

$ git grep -c 'a_snapshot_captures_a_dirty_tree_and_nothing_else\|the_worktree_listing_reads_gits_own_attributes' origin/main -- 'crates/**'
$ echo $?
1

Neither exists. CLOUD-780 deleted worktrees and stash_create outright and their tests with them — confirmed on main: git grep 'worktree_remove\|stash_create\|fn worktrees' over crates/ returns nothing, while DISCOVERY_REDIRECTS survives, which is the deletion CLOUD-740 still legitimately owes.

§3 of the same block says "worktree reclaim remains the tree's one destructive row and keeps its dry-run and --yes obligations." That verb retired with CLOUD-780.

$ mise run ready-lint < CLOUD-740.json
ready-lint: CLOUD-740 satisfies the checkable Ready clauses

What makes this the sharpest possible instance rather than an ordinary staleness bug: the row was already corrected by hand. Its reopen header, written 2026-08-21, says in its own words:

"The care notes below about locked/prunable, the main checkout's position, and the untracked-only snapshot describe deleted code and are historical."

The correction landed in the prose above the Ready block. The Ready block — the part ready-lint reads, and the part an implementer builds from — still demands them. A human read this row, understood exactly what had gone stale, wrote it down, and the stale obligations survived anyway. That is what a missing gate looks like: prose is feedforward, and only a gate is feedback (non-negotiable rule 2).

CLOUD-740 is blockedBy CLOUD-739 today, so it is not on the frontier this hour. That is luck, not a mechanism.

---

Refinement — Ready

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

• Source of truth (§1). A new gate beside ready-lint, not inside it, and the reason is ready-lint's purity rather than tidiness: it is called from board-write-record's hook, where the cwd is the tool call's and not required to be inside this project. Teaching it to read files would make its verdict depend on where a hook happened to fire — which is CLOUD-824's defect class exactly, arriving in a second place. The new gate resolves its root through git::repo_root's answer and refuses rather than guessing when it cannot. spec-ref-check is the shape to copy: same payload-on-stdin input, same pointer-only report, the cross-reference pointed at the tree instead of at the issue.

• Computable predicate (§2), and it is deliberately narrow so it decides rather than estimates (non-negotiable rule 3). Two sub-predicates, both mechanical over the Ready block's text:

  1. Cited test names. A backticked token inside §7 matching ^[a-z][a-z0-9_]*$ with three or more underscores is a test-name citation, and must appear somewhere under crates/ or tests/. The threshold is what makes it decidable: it captures this repository's actual test-naming shape (a_snapshot_captures_a_dirty_tree_and_nothing_else, no_second_git_invoker_exists, every_stays_shelled_out_claim_names_its_price) and excludes ordinary API names (check_ignore, stash_create, update_ref — one underscore each), so a false positive costs a rename rather than a wrong refusal.
  2. Cited paths. A backticked token anywhere in the Ready block containing / and ending in a source extension is a path citation and must exist in the tree. Zero-judgement and zero false positives.

• Two false-positive sources, both measured by running §2 by hand against CLOUD-740 on 2026-08-21. The second is the dangerous one, because it makes the gate PASS.

  $ grep -oE '`[a-z][a-z0-9_]*`' 740.md | tr -d '`' | awk -F_ 'NF>=4' | sort -u
    OK      a_snapshot_captures_a_dirty_tree_and_nothing_else
    OK      gix_is_confined_to_this_module
    OK      no_second_git_invoker_exists
    ABSENT  the_worktree_listing_reads_gits_own_attributes
  

  1. A superseded block in the same body. CLOUD-740 now carries two Ready blocks — one headed SUPERSEDED, kept deliberately so a reader can see which clauses went stale. the_worktree_listing_reads_gits_own_attributes is flagged from the superseded one, correctly absent and carrying no obligation. The scan is over the LIVE block, which for a body with two is the last **Refinement — Ready opener — the same first-occurrence-wins rule ready-lint applies, inverted, and it has to be stated because ready-lint and this gate would otherwise disagree about which block they are judging.

  2. A fixture that quotes the issue. a_snapshot_captures_a_dirty_tree_and_nothing_else reports OK, and its only match in the tree is:

     tests/fixtures/board-diff-overlap/CLOUD-740.md:5:  … pinned by `a_snapshot_captures_a_dirty_tree_and_nothing_else`.
     

     That file is a copy of this row's own prose. The test does not exist; a fixture quoting the citation does. A gate that resolves a citation against a quotation of the citation is vacuous — CLOUD-418's exact shape, occurring inside the gate written to prevent it. The corpus excludes tests/fixtures/, and a citation resolving only there is a refusal, not a pass.

  Both were found by running the predicate rather than by reading it, which is why they are in §2 rather than discovered during implementation.

• It checks existence, never relevance, and says so in the refusal. Whether a test that exists is the right test is not computable, and a gate that pretended otherwise would be a judge — ready-lint's own header draws that line for CLOUD-93 and this inherits it.

• A block citing nothing passes, and the count is reported. CLOUD-824's §7 names no test symbol and is a perfectly good §7. Vacuity here is legitimate, so the guard is visibility rather than refusal: the report states how many citations were resolved, and a 0 is legible instead of silent. That is the narrowing this gate can afford where board-sweep cannot, and it is stated so the difference is deliberate.

• Effect (§3). read. It reads the payload and the working tree and writes nothing.

• Output & exit (§5). Pointer-only per non-negotiable rule 4: the issue key, the clause, the unresolved token, and a count — never a line of the Ready block and never a line of a source file. Exit 0 every citation resolves / 1 a citation names nothing in the tree / 2 the payload could not be read or the tree could not be resolved, matching ready-lint and spec-ref-check so all three compose under one contract (house-style §6–§7).

• Commit / bump (§6). feat → patch until 0.1.0; below that release-plz patches whatever the type says.

• Test obligation (§7). tests/ready-cites-check.bats over fixture payloads. Shown able to fail per CLOUD-418, and the discriminating case is on the real board rather than invented: pointed at CLOUD-740's current §7 the gate must exit 1 and name both absent tests. Plus: a §7 citing a test that does exist passes; a §7 citing no candidate passes and reports zero resolved rather than reporting clean silently; a cited path that does not exist is refused; a one-underscore API name is not treated as a citation, which is the false-positive guard and the case that must be shown able to fail if the threshold is wrong; and the report carries no body text and no source line.

  Two more, one per false-positive source above, and both have a real fixture on disk:

  • A body carrying a SUPERSEDED block and a live one is judged on the live one only — red if the live block cites an absent test, green if only the superseded block does. CLOUD-740 is exactly that body today, so the fixture is a fetch rather than an invention.
  • A citation whose only match is under tests/fixtures/ is refused. tests/fixtures/board-diff-overlap/CLOUD-740.md is the live instance and makes this case red against a naive corpus — which is the discriminator for the vacuity, and the one a reviewer should ask to see fail first.

• Blockers (§8). None. relatedTo CLOUD-740, the measured instance; relatedTo CLOUD-780, whose deletion is what went stale; relatedTo CLOUD-418, which is why the discriminating case is mandatory; relatedTo CLOUD-825, the sweep this becomes an eighth gate in.

Done

main carries the gate, it is red against CLOUD-740's current §7 and green against a repaired one, and CI green on the merge commit landed by fast-forward.

Not in scope

Repairing CLOUD-740, CLOUD-738 or CLOUD-739 — those are their own rows and the repair is what this gate makes verifiable. Judging whether a cited test is the right test. Widening the citation grammar past the two sub-predicates in §2: a looser rule is a rule that estimates, and this repository's gates decide.

CLOUD-751 Every new gate ships without a measured firing rate: make a retroactive corpus replay a §7 obligation, using this repo's own agent-authored history

Why

CLOUD-514 demanded a firing rate of a candidate predicate, measured it at 99.5% false positives, and rejected it. That is the standard this repository should hold every gate to. It is met almost nowhere.

• CLOUD-514 then shipped filed-here-check with no firing rate of its own.
• assertions-not-gutted chose severity = "warn" over deny on the judgement that "a refactor legitimately merges assertions" — plausible, and unmeasured.
• no-new-ignores ships deny with no recorded replay.
• CLOUD-418 already established that a gate must be shown able to fail. Showing a gate can fail on a fixture is a different and weaker claim than knowing how often it fires on real history.

The practice exists in one issue's body and binds nothing. Non-negotiable rule 2 applied to the rules themselves: a standard without a mechanism is prose.

The corpus is already here, and it fits better than any public benchmark. This repository is agent-authored at ~40 commits/day — 75 in the 24h before filing. A candidate predicate can be replayed over its own history in one command:

prev=""; for c in $(git rev-list --reverse -N origin/main); do
  cur=$(<predicate> "$c")
  [ -n "$prev" ] && [ "$cur" -gt "$prev" ] && git log -1 --oneline "$c"
  prev=$cur
done

Measured 2026-08-20, and it is why this issue exists. A candidate kind = "ratchet" over deferral markers (TODO|FIXME|todo!() across crates/**/*.rs, justified by published agent failure rates, was replayed before being proposed:

baseline on origin/main:  202 tokens (196 TODO, 5 FIXME, 1 todo!( )
replay over 59 commits:   2 would-fire
false positives:          2 of 2  (100%)

Every one of the 202 is a test fixture or rule-pattern string — Batten's canonical example rule is no-todo with pattern = "TODO", so the repository's own vocabulary is the token being counted, and both firing commits are tests of that feature. The design was rejected on the measurement rather than shipped on the citation. That replay cost one command and would have caught a deny gate that fires only on false positives.

What this is not. Not a demand that every gate be warn until proven. Not a similarity score or a quality judgement. It is one number, reported, before a severity is chosen.

Acceptance

• A Ready block introducing a new [[rule]] or a new mise-tasks/*-check carries a replay result: commits examined, times fired, and how many of those firings were false positives.
• A block that declares severity = "deny" without one is refused by ready-lint.
• The refusal names the missing clause and the harness, so the remedy is one command rather than a research task.
• The existing corpus of Ready blocks is not retroactively invalidated — the check applies to blocks introducing a gate, and says nothing about the rest.

Refinement — Ready (one number, before a severity is chosen)

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

• Source of truth (§1). The Definition of Ready document's §7 is the authority for what a test obligation must contain; this adds one clause there, and ready-lint gains the predicate over it. No second standard, and no new document — the gate document already owns §7 and ready-lint already parses it for §6 and §8.
• Computable predicate (§2). Over the Ready block's text: if the block introduces a gate — a fenced [[rule]] declaration, or a mise-tasks/…-check path — and declares deny, it must also carry a replay line reporting commits examined and firings. Presence and shape only, never whether the number is good: judging an acceptable false-positive rate is a model verdict and non-negotiable rule 3 forbids it (CLOUD-93). The author reports; the reader decides. Runs inside ready-lint, so it composes with the existing clause checks in one invocation.
• Effect (§3). read. ready-lint reads a payload on stdin and writes nothing; this adds no command path and moves nothing in the derived allowlist.
• Output & exit (§5). ready-lint's existing contract, unchanged: pointer-only per non-negotiable rule 4 — the line number and a rule id such as deny-without-replay, never the block's prose, which may quote a consumer's data. Exit 1 for a block that is wrong, 2 for input it cannot read, matching the two codes that file already distinguishes.
• Commit / bump (§6). feat → patch until 0.1.0 (DoR §6: below 0.1.0 release-plz bumps the patch whatever the type says).
• Test obligation (§7). tests/ready-lint.bats, beside the existing clause cases: (a) a block declaring a [[rule]] at deny with no replay line fails — the discriminator, and the state every current gate ticket is in; (b) the same block with a replay line passes; (c) a block declaring warn is not gated; (d) a block introducing no gate is untouched, which is most of the corpus and the case that must not regress; (e) the report carries no prose from the block. And this issue's own replay, since a gate about replays that ships without one would be self-refuting: run the predicate over the last 60 Ready blocks and report how many would be refused.
• Blockers (§8). None — ready-lint, its suite and the DoR document are all in place. relatedTo CLOUD-514, which set this standard and is the first instance of not meeting it; relatedTo CLOUD-418, which requires a gate be shown able to fail and which this extends from fixtures to history; relatedTo CLOUD-633, which owns re-measuring a shipped prose literal's recall and is the same concern one surface over.

What this deliberately does not do. Decide the acceptable false-positive rate, or block a warn gate. A warn that fires often is noise a reader can weigh; a deny that fires often stops the fleet, which is why the obligation attaches to deny alone.

📝 Walkthrough

Walkthrough

The new ready-cites-check gate validates citations in the latest Ready block against tracked source and test files. It reports unresolved citations with stable pointer-only output and distinct exit statuses. The §6 lint now validates negative breaking-change claims. The §7 lint requires replay firing-rate evidence for newly introduced deny gates. Tests cover citation parsing, repository errors, fixture exclusion, break-claim qualification, replay evidence, and gate registration.

Accept complete negative break claims before matching their surface.

Not breaking changes to library API does not match BREAK_QUALIFIED because changes appears between the denial and library. Allow an optional change or changes term, and add a passing Bats case.

Resolve cited paths from the tracked corpus.

Line 208 accepts any existing filesystem path. A citation to tests/fixtures/..., an untracked file, or ../../outside.rs can pass. This bypasses the tracked crates/ and tests/ corpus and its fixture exclusion.

Match $p as an exact tracked, non-fixture path. Add regression cases for a fixture-only path and an untracked path.
