DO-NOT-CLOSE CLOUD-312
DO-NOT-CLOSE CLOUD-512
DO-NOT-CLOSE CLOUD-908
DO-NOT-CLOSE CLOUD-418
DO-NOT-CLOSE CLOUD-988

CLOUD-312 is the wave's owner row and reached Done at 04:35 today with 7 of its 10 guards still on disk — moved to In Review by #689's merge on a mention, despite that PR's body carrying DO-NOT-CLOSE CLOUD-312 on its own line, then swept to Done by the v0.0.114 release. That is recorded as a measurement on CLOUD-705, which owns the mention-advances-a-column defect, with the release half attributed to CLOUD-192. This PR does not attempt to reopen it.


mise-tasks/board-move-guard.sh (158 lines) and its bats suite are deleted. The predicate is a-move-to-in-review-owes-an-adjudication in batten.toml: a receipt row keyed on the issue the call names, demanding a board-move receipt no older than the 900s the row declares.

It is the third arm over one tool and the first that needed a value rather than a presence. Rows 1 and 2 split on whether the call names an id; this one splits on which column it moves to, which is what when_value exists for. A row that could only ask whether a state was present would fire on every edit naming any column — the over-fire the retiring guard's own header prices at "switched off within a day". In Progress is claim-check's question and Todo promotion is CLOUD-375's; this row does not answer for them.

The incident it exists for (CLOUD-512): a bulk sweep after #375 moved fifteen rows to In Review. CLOUD-480 was among them and nothing of it had landed — the only commit naming it carried the key in a Refs: trailer as the still-open gap. It sat wrong for 4.5 hours, and graph-check refused it in one invocation the moment it was finally asked.

Two changes the port required

graph-check writes one board-move.<KEY> per judged id, where it appended <epoch> <id> <id> … to a single file. The engine's named key is one file per subject, so the set it judged is the set of files — the same keying, asked of the filesystem instead of of a regex. Three of the guard's defences become structural: no line to parse, no word-boundary anchoring to keep CLOUD-48 from authorising CLOUD-480, and no stale-line-plus-fresh-line combination that can be constructed at all. Truncating rather than appending is what makes the mtime the age the engine reads.

The row sits before row 2. A move to In Review is also an edit, so both rows refuse a call carrying neither receipt and the engine reports the first — so the specific remedy ("adjudicate this closure") is the one the author gets, not the generic one. The two guards this replaces had the same composition and the same first-deny-wins behaviour, so what is enforced is unchanged; only which of two true refusals is spoken.

What CLOUD-418 caught in this PR's own work

Both are corrections to code I added here, not to the port:

  1. The id filter I put in graph-check had two clauses and only one was reachable. CLOUD-1/../X-1 matches the shape glob — a glob's * spans separators — so the write becomes board-move.CLOUD-1/../X-1, and board-move.CLOUD-1 is not a directory: the redirect fails and || true swallows it. The filesystem was carrying that case, not my code. A clause a test cannot observe, under a comment claiming it defends something, is what non-negotiable rule 3 refuses, so it is deleted and the comment records the measurement instead. named_validity refuses such a subject on the read side, where it is reachable and tested.
  2. The case covering it used ../escaped, which the shape clause rejects too — so it passed whether the clause under test existed or not. It uses notakey now, and the surviving clause was then observed red by removing it.

The ledger

Nineteen retiring cases placed: 10 carried, 1 subsumed, 8 changed. Six of the eight are one cause — the receipt shape — including two that moved from carried after the replay could not express them: the base rev's graph-check mints the aggregate file, so a fixture carrying the old shape carries no receipt this row can see. Both properties are carried, the allow half in a_move_with_no_adjudication_is_refused and the minting seam in the surviving graph-check.bats case that also asserts no aggregate is left behind.

Three renamed cases in graph-check.bats carry their own arms, because a rename is a deletion to anything reading names.

Verification

  • mise run replay: 46 carried cases across 3 suites answer as the bash they replaced did — rows 1, 2 and 3 together
  • row 3's four config arms each observed red alone (drop max_age, drop when_value, drop key_shape, named → branch), plus the graph-check clause above
  • both deletion directions refuse: wiring-sibling-command, wiring-declaration-stale
  • 2312/2312 cargo tests, 2932/2932 bats cases across 158 suites; corpus regenerated from a report taken after the deletion, which is the route this branch's own suite-bench refusal now forces
  • hooks-wiring-check green at 24 registrations across 5 harnesses

Tally: 2 of 10 retired before this PR, 3 of 10 after it. Rows 4, 6 and 5 are next; rows 7, 8, 10 and CLOUD-892 remain beyond them.

CLOUD-312 The engine is the pre-tool entry point; the shell guards retire behind it

Why

The pre-commit layer and CI are already adjudicated by the engine reading the committed authority. The agent tool-call layer is not: .claude/settings.json wires seven PreToolUse entries — gh-guard, ready-guard, issue-guard, run-shape-guard, memory-guard (twice, once per matcher), claim-guard — every one a mise run of a shell task carrying its own decision table, and batten hook appears in that file zero times.

Two implementations of one policy is two authorities for one fact, and the divergence is silent. A rule added to batten.toml does not reach the tool call, and a guard's table cannot be read from the config a reviewer reviews. crates/batten/src/hook.rs is the port of those guards and its own header describes the compatibility path as lasting "while they exist" — this issue is what ends that period.

It also makes the README's three-layer claim true. Today one third of it describes the design rather than the state.

The counts in this section are the pre-wiring state and are kept as the historical baseline, not as current fact. Re-counted 2026-08-20: .claude/settings.json carries thirteen registrations across six events, of which one reaches batten hook — the single PreToolUse entry. The remainder are SessionStart ×2, UserPromptSubmit ×2, Stop ×1, six further PreToolUse shell entries across five matchers, and PostToolUse ×1. CLOUD-713 owns the census that keeps that number honest; CLOUD-777 owns getting the engine onto every surface exactly once.

Mechanism

  • Each PreToolUse entry invokes the engine with the harness adapter for the host. The decision comes from the mediated_call-scoped rows of the resolved config and from nowhere else.
  • Every refusal a retiring guard renders is expressed as a config row with a required reason before that guard is removed. A guard is deleted only once its refusals are reproduced from config.
  • Fail-open posture is preserved end to end: unreadable stdin, an unparseable payload, or a missing binary all resolve to allow, and the existing bypass variables keep working.

Ready

  • Source of truth (§1). The committed batten.toml is the only table a mediated call is judged against. No decision table remains in mise-tasks/.
  • Mechanism as a predicate (§2). Two gates, both exiting 0:
    1. a differential suite replays every payload fixture in the existing guard .bats suites through the engine and asserts the same decision and the same reason text;
    2. a source-level assertion fails if any PreToolUse entry in the settings file invokes a task that carries a decision table.
  • Effect (§3). No new command surface: hook already exists and is already classified. What changes is who invokes it.
  • Output & exit (§5). Every retiring guard's refusal keeps its reason text, which is what the differential suite asserts; the deny channel per host is the one Capabilities declares. Fail-open is preserved end to end — unreadable stdin, an unparseable payload, or a missing binary all resolve to allow — so no failure code Batten can produce is one a host reads as a deny.
  • Commit / bump (§6). feat → patch until 0.1.0: below 0.1.0 release-plz bumps the patch whatever the type says.
  • Test obligation (§7). The differential suite in §2, plus the settings-file assertion, both under mise run verify and CI. A guard is deleted only once its fixtures pass through the engine, so coverage never drops below what the retiring guard had.
  • Blockers (§8). Superseded — see "Blockers, re-verified" below, which is the live list. Two rows were named here when this was written; both are resolved and their relations removed, and they are named there with their evidence. Repeating them here would be a blocker citation with no relation behind it, which ready-lint reports as blocker-cited-without-relation — measured on this row 2026-08-22, two violations, caused by removing the relations without editing this sentence. The live blockedBy relations are CLOUD-924 and CLOUD-925, per row rather than campaign-wide.

The gap is measured, not asserted

Counted against main: seven PreToolUse entries, zero invocations of the engine. The port itself is not the missing piece — hook.rs carries six harness adapters over a harness-blind core, its mediated_call matcher, and a per-host capability table — so what remains is the wiring and the config rows that make each retiring guard's refusal reproducible.

One clarification for whoever picks this up, because the neighbouring language invites the wrong move: the table hook must read is the mediated_call-scoped rows of batten.toml, not crates/batten/src/effect.rs. That module classifies Batten's own command surface for the §5 read-only allowlist, and its consumer is spec.rs. Two declared tables, two different objects; importing one into the other would put a classification of Batten's verbs in the path that judges a consumer's shell commands.

Done

main carries the engine as the pre-tool entry point with the differential suite green, no guard-local decision table remains, and CI is green on the merge commit landed by fast-forward.


The remaining inventory, re-counted 2026-08-22 against main (170c7c4)

This section is the campaign's operative content. Everything above it is history: the counts in Why are the pre-wiring baseline, and the ## Ready block's §8 is superseded by Blockers, re-verified below.

What has already changed under this row

  • Registration is finished. CLAUDE_EVENTS carries eight events (hook.rs:1013, UserPromptSubmit added by CLOUD-777) and .claude/settings.json registers batten hook --harness claude-code matcherless on all eight. There is nothing left to register, and no new registration is planned by any row in this bundle. A row proposing one is proposing a second narrowing.
  • The census moved in-process. batten doctor hooks (doctor.rs:225-344) computes the diagnosis from WiringFile and Wiring::registrations, reporting registrations / siblings / merged / merged_surfaces_read and eight stable reason ids — including hook-wiring-merged-registration, so a registration on a $HOME surface the repository does not own is visible. hooks-wiring-check.sh is now the thin caller holding this consumer's DECLARED table (:168-180).
  • The door exists and has a worked example. [[hook.handler]] landed (CLOUD-898) and batten.toml:1912 dispatches mcp-attach-check through it. That guard is therefore already retired from this table — it is dispatched by batten hook, not registered beside it.

The thirteen remaining rows

One row per entry in hooks-wiring-check.sh's DECLARED table. Destination is the load-bearing column: durable policy goes to core/config, and a [[hook.handler]] is used only where an external program intentionally remains. Two of thirteen qualify; assuming every script becomes a handler would move eleven decision tables out of the committed authority and behind a dispatch.

# Event / matcher Command (lines) Owner Destination Blocker & ordering
1 PreTool .*save_issue mise-tasks/issue-search-guard.sh (93) 312 config — a receipt row over the search receipt none; first in the board family
2 PreTool .*save_issue mise-tasks/issue-read-guard.sh (117) 312 config — a receipt row with the recency bound facts::Sourced borrowed from it none; after 1 (shares the matcher and the receipt store)
3 PreTool .*save_issue mise-tasks/board-move-guard.sh (158) 312 config — a receipt row keyed on the issue key none; after 2
4 PreTool .*(subscribe_pr_activity|send_later|create_trigger) mise-tasks/connector-verb-guard.sh (174) 312 config — but the predicate is a tool-name suffix, and no rule kind selects on one today; [[verb]] names a shell program blocked on CLOUD-924 — no rule kind keys on the tool a call names, and this guard matches by SUFFIX deliberately
5 PreTool ^mcp__ mise-tasks/connector-allow-guard.sh (88) 312 config — needs a connector-grant table in batten.toml; the grants live in .claude/settings.json today blocked on CLOUD-924 (the selector), plus that grant table
6 PreTool Task mise-tasks/fanout-guard.sh (158) 312 config — Field::Prompt exists, but [budget.<name>] is a file-set budget over globs, not a per-call ceiling blocked on CLOUD-925 — [budget] counts a file set, so a per-call ceiling is inexpressible
7 PostTool .*save_issue|.*save_comment mise-tasks/board-write-record.sh (329) 312 core — it derives a record from a tool response, which is exactly the capture bundle's first consumer ordered after CLOUD-919; porting it first would build a second reader of the response
8 UserPromptSubmit mise-tasks/mcp-allow-check.sh --session (415) 312 handler — reads settings files and MCP client logs, not the envelope; its sibling mcp-attach-check already went this way none; the door is landed
9 Stop mise-tasks/stop-guard.sh (318) + five gates (1,412) 892 config / core CLOUD-892 owns it end to end
10 SessionStart .claude/hooks/session-start.sh (295) 312 handler — it provisions a toolchain and preflights the container. There is no decision table in it to move; it is deliberately synchronous and deliberately loud on failure none, but see the bound below
11 PreTool Bash mise-tasks/run-shape-guard.sh (647) 821 config, partially — Field::RunInBackground landed, so the exemption predicate is expressible CLOUD-613 for the heredoc-binding family; CLOUD-821 owns the row
12 Stop, merged $HOME stop-hook-git-check.sh 605 / 893 out of repo — not ours to port CLOUD-893 owns visibility, CLOUD-605 the identity conflict
13 SessionStart, merged $HOME session-start-git-identity.sh 605 / 893 out of repo — same as 12

Row 10 carries a bound the door does not give for free

[[hook.handler]] imposes a timeout_ms, and this script's whole reason for existing is that a cold mise install inside the MCP client's startup window took 24s. A bound tighter than the cold path turns a fail-open handler into the absence the hook was built to close. So its handler row declares a measured bound, and the migration records the cold measurement beside it — the same standard mcp-attach-check's timeout_ms = 2000 was held to.

Per row, the two obligations this issue has always carried

Unchanged in substance from Mechanism above, restated because the table needs them per row:

  • Differential test. Every refusal the retiring script renders is reproduced from the committed authority before the script is deleted, proved by replaying that script's own .bats fixtures through the engine and asserting the same decision and the same reason text. A handler destination has the same obligation with the door in the path: the fixture goes through batten hook, and the reply is byte-compared.
  • Exact deletion condition. The script, its DECLARED row, and its bats suite go in one change, and only once its fixtures pass through the engine — so coverage never drops below what the retiring guard had. A DECLARED row naming a deleted command already fails as wiring-declaration-stale, and a command with no row already fails as wiring-sibling-command, so both directions of the deletion are gated rather than reviewed.

Blockers, re-verified 2026-08-22 — this supersedes §8 above

  • CLOUD-446 — cleared, Done. The claimed-key lookup it called unreachable from the mediated path is reachable: CLOUD-776 landed the agent-sourced fact channel, and claim-not-raced is its worked instance.
  • CLOUD-461 — cleared, landed (In Review). The advisory channel is on main, and contract-drift retired with it. Its own release is not this row's precondition.
  • New, per row rather than campaign-wide, and filed rather than deferred: rows 4 and 5 are blocked on CLOUD-924 (no rule kind keys on the tool a mediated call names); row 5 additionally needs a connector-grant table in batten.toml; row 6 is blocked on CLOUD-925 ([budget] counts a file set, so a per-call ceiling is inexpressible); row 7 is ordered after CLOUD-919. Nothing blocks rows 1, 2, 3, 8, 10.
  • Two rows first named here as blockers are Done, and naming them would have been the defect this table gates against. CLOUD-684 (MCP allow rules naming labels host servers never register under) and CLOUD-734 (re-projecting the grants at SessionStart) are both closed. What row 5 actually lacks is a config surface, which is why CLOUD-924 exists and those two do not appear above.

Stating them per row is the correction: a single campaign-wide blockedBy is what let this row sit blocked on a capability that only one of its thirteen entries needed.

The end-state test

Three predicates, all decidable by machinery that exists:

  1. Exactly one Batten registration per supported event, per harness — doctor hooks already fails hook-wiring-event-registered-n-times and hook-wiring-event-unregistered, and hook-wiring-matcher-narrows on any matcher at all.
  2. No unmanaged sibling command — doctor hooks reports siblings == 0 and merged == 0, or every remainder is a DECLARED row naming a key that is still open. A row naming a closed key already fails, which is what keeps this from becoming a permanent waiver list.
  3. Every remaining dispatched behaviour is declared in committed configuration and validated from it — each surviving program is a [[hook.handler]] row in batten.toml with a declared bound, and its behaviour is pinned by a differential case run through the door. Nothing reaches a hook surface that the committed authority does not name.

Done is the three above holding together, with main green: not "the scripts are gone", because a deleted script whose refusals nothing reproduces is a coverage loss wearing a retirement's clothes.

CLOUD-512 Nothing gates a move to In Review, so a bulk sweep can label unlanded work as landed and `graph-check` only finds out if someone thinks to run it

Why

graph-check already decides this correctly. Its in-review-no-pr rule refuses an In Review issue carrying no PR attachment, and CLOUD-309 landed it as a precondition of the release sweep after exactly this failure — CLOUD-228 and CLOUD-231 sat In Review with attachments: [] and released reported both shipped.

Nothing binds the transition itself. An agent writing save_issue(state: "In Review") passes through no gate at all, and the wrong label then survives until somebody independently decides to pipe a closure through graph-check.

Measured 2026-08-13. A bulk sweep after #375 moved fifteen issues to In Review. CLOUD-480 was among them and nothing of it had landed: the sole commit naming it, fe79792, carries CLOUD-480 in its Refs: trailer as the filed gap — that commit's own body reads "A gate not in it is a filed row (CLOUD-480), never a silent exemption." mise.toml:206 still named 7 gates against ~44 in the tree. The sweep had read git log --grep and treated a match as a landing, which is the trap mem:workflow/board-states names in so many words: "released resolves refs from commit messages, so an issue a commit merely CITES reads as shipped."

It sat wrong for 4.5 hours, and was caught only because a human asked for a review of the session's board writes. graph-check refused it in one invocation the moment it was finally asked — the gate was never wrong, it was never consulted.

The same sweep produced the inverse error twice, which is why the fix is a gate rather than more care: CLOUD-475 (b5807d8) and CLOUD-485 (cd1d105) both genuinely landed in #375 and both carried no attachment, because that PR's body never named them — they were added to the branch as its conflict resolution. Honest column, missing evidence. So a hand-run sweep gets it wrong in both directions, and only the gate distinguishes them.

Refinement — Ready

  • Source of truth (§1). graph-check's existing in-review-no-pr rule, unchanged and uncopied. This issue adds a trigger, never a second predicate — a re-derived copy is the CLOUD-351 shape this repo keeps paying for.

  • Mechanism as a computable predicate (§2). A PreToolUse guard on mcp__Linear__save_issue that refuses an input setting state to In Review unless a graph-check receipt exists for this turn — the shape ready-guard already uses to refuse gh pr ready without verify and linear-check receipts.

    The receipt is what makes this computable at all: no tracker credential exists in a hook (ci-drift's header states the split — agents fetch, gates decide — and no task in mise-tasks/ fetches from Linear), so the guard cannot look the issue up. It does not need to. It asks only whether the closure was adjudicated, and graph-check writes the receipt when it exits 0. The agent fetches the payloads; the gate decides; the guard checks that the decision happened.

  • The receipt must be keyed to the issue set, not to the turn (§2). A receipt naming which ids were judged is what stops the obvious evasion — run graph-check over one clean issue, then sweep fifteen. Same reasoning as ready-guard keying its receipts to a HEAD rather than to a session.

  • Deliberately not in scope (§2). The In Progress → In Review drain (an issue that landed and was never moved), which is CLOUD-469's. Todo promotions with no Ready block, which is CLOUD-375's. Making the attachment appear automatically for a bundled PR — a real gap this session hit twice, but it is a land/PR-body question, not a board-transition one.

  • Effect (§3). read. A PreToolUse hook body reading a payload on stdin and a receipt from $GIT_DIR; no new verb, no SURFACE row.

  • Output & exit contract (§5). The guard's existing shape — the permissionDecision: "deny" JSON channel, pointer-only: the issue id, the missing receipt, and the command that produces one. Never the issue body.

  • Commit / bump (§6). feat(hooks) — patch until 0.1.0.

  • Test obligation (§7). tests/ alongside the other guard suites, mutation-checked per CLOUD-418 — removing the receipt check must turn these red:

    • a save_issue moving one issue to In Review with no receipt → denied, and the refusal names graph-check;
    • the same call with a receipt covering that id → allowed;
    • a receipt covering a different id → denied (the evasion above);
    • a save_issue that does not touch state → allowed, untouched;
    • a move to any other column → allowed, since this rule is about one transition;
    • and the anti-vacuity partner: a guard that denied everything would pass the first four, so a case asserting the ordinary allowed path stays allowed.
  • Blockers (§8). None. Relations: CLOUD-309 established the predicate and bound it to the release sweep only; CLOUD-480 is the measured instance; CLOUD-469 and CLOUD-375 are the adjacent columns, deliberately excluded; CLOUD-508 is the general shape — an issue update written against a read that was never adjudicated; CLOUD-418 supplies the mutation obligation.

Acceptance

  • An issue cannot be moved to In Review without its closure having been judged, and the refusal names how to judge it.
  • A genuinely landed issue with its PR attached moves without friction.
  • The rows fail when the receipt check is removed.
  • No second copy of in-review-no-pr exists anywhere in the tree.

Filed from a review of one session's board writes, where the gate that would have caught this existed, was correct, and was never invoked.

CLOUD-908 `retires_with` conserves files, not logic: the one completed port deleted 22 bats cases and six of them have no successor anything in the tree can name

Why

CLOUD-807 landed retires_with, which admits deleting a bats suite exactly when its declared # subject: dies. That was the precondition for retiring anything, and it is correct. It conserves files. Nothing conserves logic. The ratchet asks "is the subject gone?" and never "did the cases move?", so a migration can delete a 259-line suite and land green with nothing asserting what replaced it. CLOUD-843 names this as the trap the permit created: "the ratchet will admit deleting a suite whose task died, with nothing asserting the Rego that replaced it. The permit made coverage evaporation quiet."

Measured on the one retirement that has actually happened

dd1d6d8 / 076b65f deleted mise-tasks/contract-drift.sh (215 lines) and tests/contract-drift.bats (259 lines, 22 @test cases), replacing them with crates/batten/tests/contract_drift.rs (12 #[test]) plus 6 unit tests in src/contract.rs. It is a careful port — the header states which half each layer covers, several cases carry an explicit "Fails by:" clause, and one is labelled "carried over verbatim in meaning".

It is also unverifiable. Mapping the 22 by hand, six have no successor identifiable from the tree:

dropped case plausible successor, unrecorded
it names the event it was called on —
an untracked file under mise-tasks is not contract possibly contradicted — see below
a payload with no session_id still works, on a shared key —
unparseable input fails open crates/batten/tests/cli.rs?
empty input fails open crates/batten/tests/cli.rs?
the bypass is honoured crates/batten/tests/guardrail_bypass.rs?

Three of those are plausibly generic batten hook properties now, held by the engine rather than the script — which is a good outcome and exactly what migration should produce. Nothing in the tree records that it happened. The only way to find out is to open two files and re-derive the mapping by hand, which is what a 20-gate batch makes impossible and what retires_with admits silently.

And one case changed behaviour deliberately, with nothing marking it. The bats suite asserted "an untracked file under mise-tasks is not contract". The Rust successor writes an uncommitted mise-tasks/brand-new-gate and asserts it is drift, with the reason in a doc comment ([epoch] tracked structurally cannot see a file that did not exist when the list was written). That is defensible. It is still a behaviour change, and no mechanism distinguishes it from an accident.

The mechanism: three arms, decidable from two trees

The deleting PR declares, per @test case in the dying suite, exactly one of:

  1. carried — names the test_ rule or #[test] that now holds it. Feeds the differential replay.
  2. subsumed — names a general property elsewhere (guardrail_bypass.rs, cli.rs, an engine invariant) that now covers it, because the plumbing it tested became the engine's rather than the script's.
  3. changed — deliberately, with the reason, as the untracked-file case above.

An unmapped case refuses the deletion at deny. No network, no judgement — the same class retires_with already is, reading a declared token out of the base tree (rules.rs:3805-3902, git.rs:1661) and refused at load without base.

The mapping is declared, never inferred, for the reason CLOUD-807 already established for # subject:: measured, 19 of 141 suites have no same-named mise-tasks/ program and all 19 are legitimate. A name heuristic over case titles would be worse — titles are prose.

Second job, and it is why this row is worth its own mechanism rather than a review checklist: the mapping is the handoff ledger. It is committed per gate as a wave proceeds, so a different session — or a different account — reads progress off the tree instead of off a chat transcript that dies with its container. A gate with no mapping block is untouched; a block with unmapped cases is half-done.


Refinement — Ready

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

  • Source of truth (§1). The two trees the ratchet already reads — the base rev's suite and the head's successors. The mapping is declared in the head tree beside the rule it belongs to; there is no second register of what has migrated.
  • Computable predicate (§2). A change deleting @test cases from a suite whose declared subject died is admitted iff every deleted case carries exactly one of the three arms and each arm's named target resolves in the head tree. Any unmapped case, any arm naming a target that does not exist, or more than one arm on one case → exit 2, at severity deny.
  • Effect (§3). read — two trees, no network, no spawn. It extends an existing ratchet rather than adding a rule kind.
  • Generated artifacts (§4). schema/batten.schema.json and schema/batten.local.schema.json regenerate for the new row key. derived-check and schema-check gate both. Regenerate with mise run fix; never merge a generated diff.
  • Output / exit (§5). Pointer-only: the refusal names the suite, the case count and the unmapped case's path:line — never the case body, and never the deleted assertion's text.
  • Commit / bump (§6). feat(rules) — not !: an additional optional column on an existing rule kind, so no published shape is broken and no consumer's config stops loading.
  • Weakens: rule-predicate-changed at rule[bats-tests-not-deleted].conserves — adding the conserves column moves that rule's predicate, and WeakeningKind::RulePredicateChanged is "reported as a change, never as a ranking" (crates/batten/src/trust.rs), because whether one predicate is narrower than another is a judgement that module refuses to make. So a tightening declares itself through the same clause a loosening would. The direction here is stated rather than left to the reader: the column only ever ADDS an obligation — a deleted @test case carrying no arm was admitted before and is refused after — and no deletion that bats-tests-not-deleted already admitted becomes admissible.
  • Test obligation (§7). Shown able to fail (CLOUD-418), one observed red each: (a) a deletion with one unmapped case is refused; (b) an arm naming a test_ rule that does not exist in the head tree is refused; (c) a case carrying two arms is refused; (d) a fully mapped deletion whose subject died loads and passes — the positive arm, which without (a)–(c) would be a rule that admits everything; (e) a deletion whose subject still exists still denies, so this row does not weaken retires_with's existing clause.
  • Blockers (§8). None.

Acceptance

  • The three arms are declarable and an unmapped case refuses at deny.
  • Each of (a)–(e) has been observed red or green as stated, not asserted.
  • The calibration is landed, not planned: contract-drift's 22 cases are mapped retroactively. Each of the six above is resolved to subsumed with a named target, or to carried, or it is a real coverage gap and gets its own row — and the row that finds a gap is worth more than the mechanism that found it.
  • The mapping's location and shape are documented as the handoff ledger, so a resuming session reads progress from the tree.

CLOUD-418 A new gate is never shown to fail, so a test that cannot discriminate ships as coverage

Why

This repository's most-repeated failure is a claim nothing exercises. land's refusal branch was dead code for months (CLOUD-235). timeout-check's budgets were placeholders that could not fire (CLOUD-352). A shape rule whose pattern was a program could never match and read as coverage (CLOUD-401). Each was caught after the fact.

It happened again, live, while building the landing lease (CLOUD-393). A concurrency test was written for a real race — observe() reading FETCH_HEAD, which is one file per clone while the heartbeat runs beside held/release in the same checkout. The test was green. Then the buggy version was restored to check the test could catch it, and it passed on the broken code too: every process fetches the same lease ref, so a crossed read yields a different generation of the same lease rather than an observably foreign one. The test asserted nothing.

That was found only because someone chose to mutate and re-run — a discipline nothing asks for and nothing checks. The green suite before that check and the green suite after it were indistinguishable.

Root cause. The obligation is stated as "a rule ships with a runnable gate" — a gate that exists. Nothing requires evidence the gate discriminates. A test that passes on both the fixed and the broken code satisfies every rule this repo currently has.

Scope, deliberately narrow. Not mutation testing over the workspace, which is a research project and a large CI bill. The claim here is about mise-tasks/*-check and the guards — the files whose entire purpose is to refuse — where the mutation is usually a one-line inversion and the suite is bats, so a run is seconds.

Refinement — Ready

  • Source of truth (§1). The gate's own suite, run against a deliberately broken copy of the gate. A pass there is the defect; the verdict is an exit code, not a judgement.
  • Mechanism (§3). Undecided between two, and choosing is what Ready needs:
    • Author-side, checked in. Each gate declares one or more mutant cases — a stated one-line corruption and the test name that must go red. A task runs them, and a mutant nothing catches fails. Costs the repo one small fixture per gate; runs locally, off the landing path.
    • Scheduled sweep. A weekly job applies mechanical mutations to mise-tasks/*-check and reports any whose suite stays green. No per-gate authoring, weaker coverage, and it belongs beside branch-age-check in the hygiene sweep, so no new CI minutes.
  • Deliberately not in scope (§2). Mutation coverage of crates/. Different tooling, different cost, different question.
  • Output (§7). Pointer-only: the gate, the mutant, and the test that failed to notice. Never a diff of the mutated source.

Test obligation

The mechanism must catch the case that motivated it: the FETCH_HEAD mutation of mise-tasks/land-lock against tests/land-lock.bats as it stood before the structural assertion replaced it. That pair is a known-good fixture — a real gate, a real mutant, and a real suite that missed it.

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

Blockers (§8): none.

Acceptance

  • Every *-check task has at least one mutation its suite is proven to catch.
  • A gate whose suite passes on a broken copy fails.
  • The land-lock/FETCH_HEAD pair is covered as a regression fixture, so the case that motivated this cannot recur silently.

CLOUD-988 A receipt row cannot declare a maximum age, so CLOUD-508's recency bound has no config surface and row 2 stays bash

Why

CLOUD-987 landed ReceiptKey::Named, so a receipt row can now be keyed on a value the mediated call names — which subject the receipt is about. CLOUD-312's row 2 needs one thing more, and it is a different kind of thing: how old the read was.

issue-read-guard is a recency bound, not an existence check. issue-read-check mints read_at=<epoch> and the guard compares it against now with a 300s window; the receipt's own success line says so — "an update is authorised for the next 300s." Existence is not the predicate. A receipt from yesterday exists and must not authorise today's write, which is the whole of CLOUD-508: a groom landed on an issue that had been marked a duplicate between the read and the write.

No rule column can say that, and the reason it cannot is a deliberate invariant rather than an oversight. A maximum age needs a clock, and hook::adjudicate reads none — pinned by hook::tests::adjudicate_reads_no_clock_even_now_that_a_waiver_can_lapse. That pin is load-bearing: a decision function that reads a clock is one whose verdict depends on when it ran, which is unreproducible and untestable without freezing time.

The shape the answer has to take, and there is already a precedent for it

The boundary supplies the clock; the decision compares. That is exactly how the waiver table works — waiver::today's idiom, quoted in facts::Sourced's own doc: "no predicate here reads a clock (the caller supplies one)." CLOUD-610 already moved the waiver facts to boundary-resolved for this reason.

So the pieces are:

  • a column on a receipt row declaring the maximum age its receipts may carry;
  • a read_at-style field the receipt store already writes, read at the boundary;
  • now resolved once at the boundary and handed in beside the other facts, never taken inside adjudicate;
  • Validity gaining a stale-by-age answer, distinct from Missing — a receipt that exists and expired is a different thing from one that was never taken, and collapsing them would report "never read it" to someone who read it an hour ago.

Two existing rows are the reason to be careful about the tests. CLOUD-521 records issue-read-guard.bats case 590 asserting an exact elapsed second and failing on a one-second fixture race; CLOUD-724 records a fifth wall-clock-graded test flaking a land lap. So the age comparison must be tested by INJECTING the clock, never by sleeping — which the boundary-supplies-it shape makes natural rather than merely possible.

What this blocks

CLOUD-312's row 2 (issue-read-guard, 117 lines) stays bash until this lands. CLOUD-987 gave it the right key and cannot give it the bound.

Rows 1 and 3 are not blocked by this — their predicates are over argument presence, which CLOUD-987 delivered, and they need no clock.

Refinement — Ready

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

  • Source of truth (§1). crates/batten/src/receipt.rs's Validity and verdicts, rules.rs for the column, and lib.rs's boundary for the clock. mise-tasks/issue-read-check.sh is the receipt shape being read and issue-read-guard.sh the behaviour being reproduced; its header is the specification of what must not collapse.
  • Computable predicate (§2). A receipt row declaring a maximum age treats a receipt older than it as stale-by-age and one at or within it as valid — the <= boundary budget.rs sets, inherited rather than re-decided. adjudicate still reads no clock: the pin stays green, which is the assertion that this was done the right way round.
  • Effect (§3). read at the boundary, behind CLOUD-460's narrowing so a repository declaring no age bound resolves no clock. free inside the decision — a comparison of two numbers it was handed.
  • Generated artifacts (§4). schema/batten.schema.json, derived and drift-gated; hook.rs and rules.rs are both in schema-check's glob.
  • Output & exit (§5). The 0/1/2/3 table unchanged. A stale-by-age refusal names the row and the bound, never the receipt's timestamp or the subject's content — the age is a duration, which is a pointer-shaped fact.
  • Commit / bump (§6). feat(rules) → patch until 0.1.0.
  • Test obligation (§7). The clock is INJECTED, never slept on (CLOUD-521, CLOUD-724): a receipt exactly at the bound is valid and one a second past it is not, both from a fixed now; an absent receipt is Missing and an expired one is stale-by-age, asserted as distinct so the two cannot collapse; and adjudicate_reads_no_clock_even_now_that_a_waiver_can_lapse still passes, which is the invariant this must not buy its way past. Shown able to fail per CLOUD-418: reading the clock inside adjudicate reds that pin, and collapsing stale-by-age into Missing reds the distinctness case.
  • Blockers (§8). None. blocks CLOUD-312 row 2. relatedTo CLOUD-987 (the key this completes), CLOUD-508 (the measured incident), CLOUD-610 (the boundary-resolved-facts precedent), CLOUD-521 and CLOUD-724 (the two wall-clock test flakes this must not reproduce).

Acceptance

  • CLOUD-312's row 2 is expressible as a committed config row with its recency bound intact rather than degraded to an existence check.
  • adjudicate still reads no clock, and the existing pin proves it.
  • Every age case is driven from an injected now; no test sleeps.

Filed 2026-08-23 by the CLOUD-911 bundle-G session, which built CLOUD-987's key variant and measured that the remaining half of row 2 is a clock rather than a key.

Review Change Stack

📝 Walkthrough

Walkthrough

The change replaces the shared graph-check receipt with per-issue board-move.<issue-id> receipts. A new batten.toml rule requires a recent matching receipt for save_issue transitions to In Review. Tests cover receipt creation, freshness, subject isolation, selectors, fail-open cases, and refusal payloads. The previous shell guard and its wiring and mutation-gate entries are removed. The change also updates target pruning, documents stale verification results, and regenerates benchmark results.

Merge Risk: 🟡 Moderate · up to 5a1c1

The PR replaces the board-move guard with receipt-based adjudication, but malformed issue keys can currently be emitted by the producer and rejected by the consumer, leading to inconsistent move validation. Merge should wait for the exact boundary-case coverage and correction; task-root handling and formatting of deleted files also remain bounded follow-up risks.

Test the exact 900-second freshness boundary.

The 4000-second and 5-second cases pass if the bound changes to 899 or 901 seconds. They also do not distinguish elapsed > 900 from elapsed >= 900. Add deterministic clock-controlled cases where 900 seconds allows and 901 seconds denies.

`board-move-guard.sh` (158 lines) and its bats suite are deleted. The predicate
is `a-move-to-in-review-owes-an-adjudication` in `batten.toml`: a `receipt` row
keyed on the issue the call names, demanding a `board-move` receipt no older than
the 900s the row declares.

It is the third arm over one tool, and the first that needed a VALUE rather than
a presence. Rows 1 and 2 split on whether the call names an `id`; this one splits
on which column it moves to, which is what `when_value` exists for — a row that
could only ask whether a `state` was present would fire on every edit naming any
column, the over-fire the retiring guard's own header prices at "switched off
within a day". In Progress is `claim-check`'s question and Todo promotion is
CLOUD-375's; this row does not answer for them.

Two changes the port required, both stated in the config beside the row:

* `graph-check` writes one `board-move.<KEY>` receipt per judged id, where it
  appended `<epoch> <id> <id> …` to a single file. The engine's `named` key is
  one file per subject, so the set it judged is the set of FILES — the same
  keying, asked of the filesystem instead of of a regex. Three of the guard's
  defences become structural: no line to parse, no word-boundary anchoring to
  keep CLOUD-48 from authorising CLOUD-480, and no stale-line-plus-fresh-line
  combination that can be constructed at all. Truncating rather than appending is
  what makes the mtime the age the engine reads. The id is shape-checked before
  it becomes a path component, which is `named_validity`'s read-side refusal
  applied to the write side.
* The row sits BEFORE row 2. A move to In Review is also an edit, so both rows
  refuse a call carrying neither receipt and the engine reports the first — so
  the specific remedy is the one the author gets, not the generic one. The two
  guards this replaces had the same composition and the same first-deny-wins
  behaviour, so what is enforced is unchanged; only which of two true refusals
  is spoken.

Nineteen retiring cases placed: twelve carried, one subsumed, six changed — five
of those six on the single cause above. Three renamed cases in the surviving
`graph-check.bats` carry their own arms, because a rename is a deletion to
anything reading names.

The suite corpus is regenerated at 158 suites from a report taken after the
deletion, which is the route this session's own `suite-bench` refusal now forces.

Verification: 2312/2312 cargo tests, 2932/2932 bats cases across 158 suites,
`hooks-wiring-check` green at 24 registrations.

… say why

Two corrections to row 3, both found by taking CLOUD-418 literally — each arm
observed red one mutation at a time, rather than asserted.

The id filter in `graph-check`'s receipt write had two clauses and only one was
reachable. The separator clause read as defending traversal, and removing it
changed nothing: `CLOUD-1/../X-1` matches the shape glob (a glob's `*` spans
separators), so the write becomes `board-move.CLOUD-1/../X-1`, and
`board-move.CLOUD-1` is not a directory — the redirect fails and `|| true`
swallows it. The filesystem was carrying the case, not the code. A clause a test
cannot observe, under a comment claiming it defends something, is what
non-negotiable rule 3 refuses, so it is deleted and the comment now records the
measurement. `named_validity` refuses such a subject on the READ side, where it
is reachable and tested.

The case that covered it was built on `../escaped`, which the shape clause
rejects too — so it passed whether the clause under test was there or not. It
uses `notakey` now, and the surviving clause was observed red by removing it.

Two ledger arms move from `carried` to `changed`: the replay could not express
them, because the base rev's `graph-check` mints the aggregate receipt and the
engine reads one file per id, so a fixture carrying the old shape carries no
receipt this row can see. Both properties are carried — the allow half in
`a_move_with_no_adjudication_is_refused`, the minting seam in the surviving
`graph-check.bats` case that also asserts no aggregate is left behind.

Verification: `mise run replay` — 46 carried cases across 3 suites answer as the
bash they replaced did; row 3's four config arms each observed red alone.

Refs: CLOUD-312, CLOUD-418, CLOUD-908
Five instances in one session, same shape: a green local check quoted over a
tree that moved after the check was taken. `lint:clippy` run before test cases
were appended; `lint:clippy` backgrounded while `rules.rs` was edited under it;
a `test:bats` run torn by a full disk and its partial output read as a pass; a
`hook` behaviour tested against an installed binary predating the fix.

And twice, the one that destroys work rather than misreporting it: `git checkout
-- <file>` to undo a mutation restores the COMMITTED file, discarding an
uncommitted repair in the same file. A mutation sweep that restores from the
index destroys exactly the change being verified.

The cost is a wasted `land` lap each time — a CI run plus a rebase. Two habits
close it, neither of which is "be careful": re-run the check after the last edit
rather than before (a step receipt keys on input content, so the second run over
an unchanged tree is nearly free), and never restore a mutated file from the
index while an uncommitted change is in it.

`verify` caught all five, which is the design working. It catches them one lap
later than a local re-run would.

Refs: CLOUD-312
…e can verify

`target-prune` refused an absent `target/` as could-not-look, and `verify` depends
on it, so a tree with nothing built could not be verified at all. Measured
2026-08-25: a session deleted `target/` to recover disk and then failed three
consecutive `land` laps here, on a tree whose only fault was having built nothing
yet. A fresh clone is in exactly that state.

`$root` is relative, so the only thing that refusal could protect against is a
caller whose cwd is not the workspace root — and that is decidable directly
rather than by proxy. Two discriminators, both needed:

* a root the caller NAMED and that is absent stays could-not-look, whatever the
  cwd holds, which is the `--root` case the suite already pinned — and which
  caught the first version of this change weakening it;
* for the DEFAULT root, a `Cargo.toml` beside it means nothing has been built, so
  there is nothing to prune and the floor is still judged. A clone starting with
  less space than a lap needs must still be told so, which is the half that would
  have been lost by simply exiting 0.

Three cases, each observed: the unbuilt tree passes and still reports the floor;
the unbuilt tree BELOW the floor still refuses, so this is not an escape hatch;
and no `target/` with no `Cargo.toml` is still exit 2.

Refs: CLOUD-312
The rebase onto `65552c3` conflicted here, which is expected for a derived file:
main added a suite while this branch removed one. Resolved by regenerating from a
report taken after the rebase rather than by merging the two tables — 159 suites,
which is 158 plus main's addition.

Reject existing non-directory roots.

At Line 169, ! -d "$root" also matches an existing regular file or special file. If Cargo.toml exists, Lines 170-176 classify that invalid root as an unbuilt workspace, skip pruning, and can return success after only the floor check. This violates the invalid-root refusal.

Apply the unbuilt-workspace exception only when $root is absent. Treat existing non-directory paths, including dangling symlinks, as errors. Add a Bats case for a regular file at target.

Proposed fix
 if [[ ! -d "$root" ]]; then
-	if [[ "$root_named" -eq 1 || ! -f Cargo.toml ]]; then
+	if [[ "$root_named" -eq 1 || ! -f Cargo.toml || -e "$root" || -L "$root" ]]; then
 		echo "::error:: target-prune: no build directory at $root — nothing was examined, and that is not the same as nothing to prune" >&2

Test the exact issue-key boundary.

notakey does not test the malformed ID that mise-tasks/graph-check.sh currently accepts. CLOUD-a-1 matches [A-Z]*-[0-9]*, so the script writes board-move.CLOUD-a-1. The receipt rule rejects that key because it requires ^[A-Z][A-Z0-9]*-[0-9]+$.

Replace this fixture with CLOUD-a-1. The existing assertion will then detect a producer-consumer key-shape mismatch.
