CLOUD-911 bundle 2 — the mediated-call retirement

[wenzowski]

Bundle G of the CLOUD-911 dispatch: the mediated-call retirement. CLOUD-911's Progress section is the authoritative ledger; this body summarises and is updated as rows clear.

Bundle 1 (#660) had to land first and now has. Verified on the tree rather than from its PR body: mise-tasks/replay.sh, replay-pointers.py and suite-select.sh are all on main, so a retirement can satisfy CLOUD-908's mapping arm and CLOUD-909's replay arm. Before that this branch was empty by design — deleting nine scripts with nothing asserting what replaced them is the one thing the dispatch forbids.

Rows

row	state
CLOUD-924 — a mediated row can name the tool it is about	done
CLOUD-925 — a per-call ceiling, both conjuncts	done
CLOUD-987 — a mediated row can condition on the call's arguments	done
CLOUD-988 — a receipt row can bound how old its receipt may be	done
CLOUD-312 row 1 — issue-search-guard	expressible now; not yet ported
CLOUD-312 row 2 — issue-read-guard	expressible now; not yet ported
CLOUD-312 row 3 — board-move-guard	expressible now; not yet ported
CLOUD-312 row 4 — connector-verb-guard	portable; coupled to row 8 (below)
CLOUD-312 row 5 — connector-allow-guard	needs the grant table moved into batten.toml
CLOUD-312 row 6 — fanout-guard	portable on 924 + 925
CLOUD-312 row 7 — board-write-record	unblocked (CLOUD-919 landed in bundle F)
CLOUD-312 rows 8, 10 — the two handler destinations	row 8 coupled to row 4
CLOUD-892 — the Stop surface	not started
CLOUD-917 — the facts.rs storage clause	not started

No script is retired yet, and the census stands at zero. That is the honest state rather than a shortfall being papered over: this bundle was dispatched to build two instruments and then run a ten-row wave on them, and the wave turned out to need two more that did not exist when it was scoped. All four instruments are here; the retirements are not, and every reason is on the board.

The inventory's readiness claims did not survive contact, in three distinct ways.

Rows 1–3 were blocked, not first. CLOUD-312's re-verified list says "Nothing blocks rows 1, 2, 3, 8, 10." All three condition on the mediated call's arguments — .tool_input.id for row 1's create/update discriminator, .tool_input.state for row 3's column move — and row 2 keys its receipt by the issue the call names, which ReceiptKey (Head/Branch) could not express. No rule column read any of it. Filed as CLOUD-987 and built here, so rows 1 and 3 are expressible now.

Row 2 needed a fourth instrument, and it is here rather than filed. Its real predicate is not which row was read but how recently — CLOUD-508's bound. A receipt row keyed to the subject the call names establishes existence and nothing more, so a read minted once authorised every later write forever. That was filed as CLOUD-988 and then built, because the gate that priced it was right to: a row naming files this branch has open, for a capability this branch's own wave needs, is a punt when it could be closed here. max_age is the column; the comparison happens at the boundary and reaches the decision as a fourth Validity, so adjudicate still reads no clock. The alternative — collapsing the row to key = "branch" — is the exact defect issue-read-check's own header refuses.

Rows 4 and 8 are coupled, and the table presents them as independent. mcp-allow-check (row 8) learns which tool suffixes are already guarded by spawning its neighbours for --covers. Deleting row 4's script makes its three suffixes drop out of that union silently, because the glob just stops matching. Detail and the fix — row 8 reading the declaration from batten config show -J instead — are on CLOUD-312.

CLOUD-987, and the defect it turned out to be

Three capabilities, two of them straightforward and one that was inert on arrival.

• A named projection of one input key. Field::InputId and Field::InputState, following Field::Prompt and Field::RunInBackground exactly: one deliberately named key read out of Envelope::input, because the allowlist's whole safety argument is that it enumerates. Appended, never inserted.
• A presence/value modifier. when_absent and when_present, so a row can fire on a key being absent (row 1's create) or holding a value (row 3's move). Same split requires_key makes: the row selects, the modifier decides whether the selection refuses. Declaring both polarities over one projection is a load error, not a row that can never fire.
• A subject-keyed ReceiptKey. key = "named" with key_from naming the projection that supplies the subject. Both directions are load errors: a named key with no projection would read one file for every call, and a projection on any other key is a column that reads as configured and is never consulted.

The third one shipped unreachable, and only a rewritten test could see it. A tool-keyed receipt row loaded, validated, and had its checks resolved at the boundary — and then reached no gate at all. The write-triggered receipt gate is the only one above the command.is_empty() early return, and a structured MCP call carries neither a write nor a command, so segments("") gave the command walk nothing to match either. This is CLOUD-924's defect one layer down, in the same chain, for the same reason.

The fix is a narrow gate rather than a wider condition, and that narrowing is measured rather than tidy. Widening the write-triggered gate to every call carrying a tool name was written first: it reaches command-keyed rows early too, and cli.rs's the_committed_shape_rules_fire_on_every_banned_shape went red — gh pr ready 42 came back refused by this repository's ready-needs-receipts instead of ready-names-an-issue. That inverts the chain's standing precedence, where a ban a reviewer wrote by hand outranks an unmet precondition, on the reasoning that there is no point telling the author of a refused call which receipt to go and earn. So tool_receipt_rules sees a row only if that row's own tool selected this call.

A path-safety refusal travels with the subject: a value carrying a separator, .., a NUL or a control character is refused, never rewritten, because rewriting would file two different subjects under one receipt and let a fresh read of A authorise a stale write to B — precisely the confusion this key exists to prevent. An unfileable subject resolves the whole receipt question to could-not-look, which allows: a judgement about the shape of an argument is not a judgement about the receipt.

Two of the three new cases asserted their own premise

This is the finding worth carrying, because both tests were green and both were worthless, and the mutation is what said so.

• a_receipt_for_one_subject_does_not_authorise_another had a shape row in its fixture banning the tool outright. Its exit 2 was never the receipt's, and it never even called with a mismatched subject. Rewritten to pair a matching-subject allow with a mismatched-subject deny — only the pair discriminates, and the second assertion is the one CLOUD-508 is about.
• an_unfileable_subject_is_could_not_look_and_allows asserted only allows, which a never-consulted row also produces. Rewritten with a live-row control first: a fileable subject with no receipt must deny in the same fixture.

Both fixtures also used .git() alone — git init with no HEAD, so repo_facts() could not resolve and every verdict went to could-not-look regardless of the row. .base_commit() now. It was the control assertion, added for the mutation, that exposed both the fixture defect and the unreachable gate; without it three green tests would have shipped over a column that decided nothing. Same subject as 50e18ae, which landed on main mid-branch: a declaration that cannot discriminate is not coverage.

CLOUD-988, and why it is in this PR rather than on the board

It was filed, and then filed-here-check refused the land — correctly. The row named five files this branch has open, which is the proximity refusal CLOUD-514 phase 3 exists for: a defect found in your own diff is one you are already holding the file for, so spinning it onto the board is cheaper than fixing it. The gate offers four ways forward and only one of them is an override. This took remedy 1.

max_age is seconds on a receipt row. The comparison happens where the receipt is already being read — at the boundary — and reaches the decision as a fourth Validity, which is the waiver table's precedent: a waiver lapses on a date, and today() is handed in rather than taken inside. So the column buys a variant and no clock in the core, and adjudicate_reads_no_clock_even_now_that_a_waiver_can_lapse still holds unchanged.

Expired is its own variant rather than Missing because the remedy differs — this says run it again where Missing says run it, the same reason the two staleness variants are not one. The refusal names the declared bound and never the measured age, so the line stays byte-stable; an elapsed second in the output is what CLOUD-521 records the cost of.

Three narrowings worth stating:

• A repository declaring no bound pays no stat, the cheap-when-irrelevant discipline required_checks_for already keeps.
• The age is read only over a receipt that was otherwise valid — a missing or stale one has a more specific answer and a different remedy, and downgrading it would replace a precise pointer with a vaguer one.
• Where two rows bound one check the tightest wins, not declaration order. Everything else on this surface breaks a tie by declaration order, and that is right when the rows name alternatives; a maximum age is a constraint rather than an alternative, so both hold. Honouring the looser one would let adding a row relax a bound already declared.

max_age = 0 is a load error: it expires a receipt the instant it is written, so the row refuses every call while reading from the file as though it permitted a fresh one.

Both arms observed red, one mutation each — older_than always false reds the aged case, disarming the zero refusal reds the load-error case. The aged case sets the receipt's mtime rather than sleeping past its own bound: rust.md is explicit that a timing assertion discriminates nothing here, and CLOUD-521 and CLOUD-724 are the recorded cost of grading on one.

This is the mechanism only. Porting row 2 off bash is CLOUD-312's row and needs the four-arm retirement protocol — mapped, replayed, remedy preserved, DECLARED row deleted in the same commit — so it stays named there rather than half-done here.

CLOUD-925, in one paragraph

[budget.] is a file-set budget evaluated over the tree, so fanout-guard's bound — count this call's prompt, refuse past a cap — had no spelling as a row. measures/counts/max is a modifier, not a fourth keying column: the row selects on tool and the ceiling decides whether that selection refuses, which is the split requires_key already makes. The <= boundary and estimate_tokens are both inherited from budget.rs rather than decided again, because one authority for what a ceiling is is the point. The manifest conjunct resolves at the boundary via git::tracked_paths — matching the shell guard's own ls-files so the differential obligation compares like with like — and None is could-not-look and allows. The consumer's mem:-style shorthand lives in a resolves rewrite column, so no reference convention reaches crates/batten.

Two defects the tests caught and review would not have: tool_rules denied on a tool match alone, so a ceiling row refused every call it selected while the cap sat unread (only the end-to-end suite could see it); and the measurement counter, first asserted as a delta on a process-global, raced two concurrent ceiling cases in one binary. The gate now reports its count through an out-parameter and the caller publishes it.

CLOUD-924, and the defect it turned out to be

The row reads as a rule-table change: give a mediated_call row a way to say which tool it is about. The table was not the blocker.

lib.rs skipped the config load entirely for any payload carrying neither a command nor a write:

if bypass || (envelope.command.is_empty() && envelope.writes.is_none())

Every MCP call, every Read, every Task spawn is that shape. So a tool-keyed row was handed Policy::declaring_nothing however carefully the gate above it was written — measured directly: with the column added and the gate wired, seven arms written, five denies red and only the two allow-only controls green, which is a build where the column loads and gates nothing.

This is the same correction CLOUD-312 already made once, and its own comment says so — "'command-less' is no longer the same claim as 'nothing to judge': a write tool carries a path and no command, and skipping the config load for it is what made the write matcher unjudgeable even once adjudicate grew the gate." A tool selector falsifies it a second time, so the condition widens the same way. A tool-keyed receipt row falsified it a third time, one gate further down, which is CLOUD-987's section above.

The cost is real and lands on the arm that measures it

perf's passthrough arm is exactly this payload — claude-code-passthrough.json is a PreToolUse Read with a file_path, no command, no write — and its below-noop reading came from taking precisely the skip this removes. That reading is load-bearing (.claude/rules/rust.md), so it was re-measured with perf-pair against the merge base rather than argued about.

Measured, and it did not cost what was predicted. 100 runs per path, p50 ms:

path	base	head	ratio
noop	2.57	2.55	0.992
passthrough	2.95	2.98	1.010
check	3.38	3.28	0.970
hook	3.09	3.19	1.032
posttool	7.04	6.91	0.982
wired	14.1	14.44	1.024

perf-gate exits 0 — every path inside 1.30x, and every ratio inside the 0.966–1.102 null band a comparison of one identical binary produces. So the config load this adds to a structured call is not measurable against process start on this machine.

A separate reading did not survive, and it was already gone at base. passthrough sits above noop in both arms (2.95 > 2.57 base, 2.98 > 2.55 head), so the documented "passthrough sits below noop" property does not reproduce here and cannot be used as a pass/fail. It is not a regression from this branch — it is inverted at the merge base too. The cause is that the arms are not the same work: noop is batten --help with no stdin, while passthrough decodes a payload, so the relation held only while process start dominated. perf-assert holds absolute budgets and never asserted the order, so nothing was switched off. Filed on CLOUD-925, whose §7 proposes that comparison as a test — the counter it also names is the sound half, and is what that row will use.

Buying the narrowing back is not available: it would mean knowing whether any tool-keyed row is declared, and only the config can answer that. What stays free is every other path — a bypassed call still never touches config, and neither does any event but the adjudicated one.

Two decisions narrower than the row's wording

• tool is permitted on shape and receipt, not pipeline. Those are the kinds a row can key with no command in hand — and CLOUD-312's rows 1-3 are receipt rows keyed on a trailing tool pattern, which the row's own table does not mention. pipeline's predicate is the operators between a command's segments; a structured call has none, so the column would load and match nothing.
• Matched exactly OR as the whole final __-delimited segment — never a bare suffix. The suffix half is the measured requirement (CLOUD-665, CLOUD-684: a rule naming a server label the host never registers under matches nothing, silently). The delimiter is the other half, and it is not cosmetic: a bare suffix makes tool = "Edit" select NotebookEdit, widening a row onto a tool nobody named. It is board-payloads' own rule and carries its reasoning.

Three keying columns means three collisions, so the one-of case enumerates the pairs instead of sampling one — with two columns "both" was the only collision there was.

Verification

mise run verify green on the head commit, rebased on current origin/main. Every CLOUD-418 arm observed red before it passed, not asserted:

• Collapsing the suffix to an exact match → 3 of 7 red, including the_prefix_the_host_minted_does_not_decide_the_verdict, which is the CLOUD-665/684 rotation replayed as a test. This is the mutation CLOUD-924 §7 names.
• Dropping the __ delimiter test (bare suffix) → exactly 1 red, a_bare_suffix_does_not_select_a_tool_nobody_named, with the other six green. A precisely discriminating arm: it isolates the delimiter and nothing else depends on it.
• Three disjoint mutations for the named key — safe_subject always true, named_validity ignoring its subject, the named-requires-key_from arm made dead — reported one red where three were expected, which is how the two premise-asserting tests above were found. Re-run after the rewrite, each arm discriminates.
• Two disjoint mutations for max_age — older_than always false, and the zero refusal disarmed — each red exactly its own arm, with nothing else moving.

Mutations were reverted and the tree confirmed byte-identical to the committed state.

A declared semver break: Rule gains eight optional columns, hook::Field two variants, ReceiptKey one, receipt::Validity one, and CeilingUnit is new. Every addition is optional in TOML, so no committed batten.toml changes meaning — the break is to callers constructing these types in Rust.

One defect this PR is better for, caught by the repo's own gate rather than by review: non-negotiable rule 1 failed the build because a consumer's settings path had reached a crates/batten doc comment — while implementing a row whose entire argument is that consumer facts belong in the consumer's config. no_artifact_name_reaches_the_core is computed, so it does not depend on a reader noticing.

What this PR does not close

CLOUD-312 stays open and gets a progress update rather than a close: no row is retired here, and after the wave does run, rows 11 (run-shape-guard, behind CLOUD-613) and 12-13 (the two $HOME scripts, CLOUD-605) still remain — so doctor hooks can never report siblings == 0 and merged == 0 from this branch. CLOUD-892 and CLOUD-917 are untouched and are not closing keys.

CLOUD-924 No rule kind keys on the TOOL a mediated call names, so the two connector guards have nothing to retire onto

Why

CLOUD-312's retirement inventory (rows 4 and 5) asks two guards to become config rows, and neither can: the rule table has no way to say "this row is about this tool."

What exists. [[verb]] rows key on MutatingVerb::verb, documented as "The program name as it appears on a command line, e.g. the basename of the executable. Matched exactly." — a shell command line, plus the write tools CLOUD-312 made verbs. [[rule]] rows with scope = "mediated_call" key on a pattern over the command text, which a structured tool call does not have. Envelope::raw_tool carries the host's own word for the tool and Envelope::operation the normalized shape, and no rule field reads either.

The two rows this blocks, and they need different things:

Guard	What it keys on today	What config would need
connector-verb-guard.sh (174 lines)	the tool-name SUFFIX — deliberately, so the verdict survives the exposed server name changing (CLOUD-178): .*save_issue matches whatever prefix the host minted	a selector matching a tool-name suffix, not an exact program name
connector-allow-guard.sh (88 lines)	the committed connector permissions, applied per call to whichever server name the host exposed (CLOUD-191)	both the selector above and a grant table in batten.toml — today the grants live in .claude/settings.json's permissions

The suffix half is the interesting one and is not a convenience. CLOUD-665 and CLOUD-684 are both the same measured failure — a rule naming a server label the host never registers under matches nothing, silently — and matching the suffix is what this repository already chose as the answer. An exact-match selector would rebuild the defect those two rows closed.

Scope

One capability: a mediated_call-scoped row may select on the tool the call names. Not a new rule kind if an existing one can carry the selector; the decision is where it lands, not whether.

Explicitly out of scope: the ask terminal state (CLOUD-340), and re-projecting grants onto the session's generated config (CLOUD-734, Done). This row is only about a rule being able to say which tool it is about.

Refinement — Ready

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

• Source of truth (§1). crates/batten/src/rules.rs's row struct and hook.rs's Policy::required_checks_for narrowing. The selector reads Envelope::raw_tool (the host's word, per CLOUD-779's split) and never the normalized Event.
• Computable predicate (§2). A mediated_call row carrying a tool selector fires on a call whose raw_tool matches and on no other; a suffix selector fires whatever prefix the host minted. Failure case: an exact-match-only selector passes a fixture named mcp__Linear__save_issue and misses mcp__linear-server__save_issue, which is CLOUD-665's measured defect replayed as a test.
• Effect (§3). free at decision time — the selector is a string comparison over a field the envelope already decoded, and the CLOUD-460 narrowing means a call no row selects for resolves nothing.
• Generated artifacts (§4). schema/batten.schema.json, derived and drift-gated.
• Output & exit (§5). No new verb; the 0/1/2/3 table unchanged. A refusal names the row id and the tool, never a byte of Envelope::input — a tool NAME is not content, which is the same argument Field::ToolName already carries.
• Commit / bump (§6). feat(rules) → patch until 0.1.0.
• Test obligation (§7). Fixtures for exact and suffix match, a negative control (a row that must not fire on a neighbouring tool), the CLOUD-665 prefix-rotation case above, and hook-matcher-check's existing both-directions assertion extended to the new selector. Mutation coverage per CLOUD-418: collapsing suffix to exact match turns the rotation case red.
• Blockers (§8). None. blocks CLOUD-312 rows 4 and 5. relatedTo CLOUD-191 (the per-call resolution this makes expressible in config), CLOUD-665 and CLOUD-684 (the measured prefix-rotation failures the suffix selector exists for), CLOUD-779 (the raw_tool / Event split this reads).

Row 5's other half is decided here rather than left as an option. Even with the selector, connector-allow-guard needs the grants themselves in the committed authority — they live in .claude/settings.json's permissions today. The first draft of this row said "if it wants its own row, file it as row 5's second blocker", which is a decision left for a later reader, so: it gets no row. A batten.toml connector-grant table is a consumer's table of a consumer's grants, and moving it is the port itself — the work row 5 of CLOUD-312 already names — not a capability the engine is missing. CLOUD-312's row 5 records it that way ("plus that grant table"), so nothing here is waiting on anything there.

The distinction that makes the split correct: the selector is an engine capability and the grants are consumer data. Non-negotiable rule 1 is why they cannot be one row — a grant table in crates/batten would be a consumer's server names in the core.

Filed 2026-08-22 while grooming CLOUD-312's inventory to Ready: rows 4 and 5 both read "config" as a destination and neither had a mechanism, which is a deferral wearing a destination's clothes.

CLOUD-911 Fleet dispatch: the bash retirement in two bundles, sized for a cross-account handoff — ten rows in one PR, then the wave in another

Eleven rows, two bundles, two lands. The bundles and prompts live here rather than in a chat that dies with its container — CLOUD-607's precedent, CLOUD-784 and CLOUD-839's shape. This row is additionally written to survive its author running out of quota mid-flight: §"Resume protocol" is how a different account computes where the last one stopped, off the tree and the board, without asking anyone.

Why two PRs and not twenty

The landing lease is fleet-wide and charges per land, not per gate. land-lock's header: "hold a rolling fleet-wide landing lease, so exactly one branch at a time spends CI on a landing attempt." ci p95 is 701 s; one lap is rebase → verify → push → ci-wait → /fast-forward, strictly serialized. CLOUD-843's own table:

batching	lease acquisitions for the campaign	pure landing time
one row per PR	~20	~5 h
two bundles	2	~30–40 min

One PR carrying many rows is the intended shape: CLOUD-661 retired the one-PR-per-ticket prescription for exactly this case and CLOUD-502 is Canceled.

Why not one PR. Two reasons. Bundle 2's content is created and validated by bundle 1's instruments — in one PR those instruments would never have been exercised against anything but their own fixtures before twenty suite deletions rode on them. And a quota stop mid-branch with everything in one PR leaves nothing landed; with bundle 1 landed, the next account inherits a repo that can already prove a migration faithful, and bundle 2 is resumable per gate.

The bundles

#	Chain	File domain	PR shape
1 the floor	CLOUD-879 → 851 → 883 → 907 → 880 → 908 → 909 → 480 → 886 — 876 moves to the head of the chain, see Verification	facts.rs, rules.rs, policy.rs, git.rs, schema/*, mise-tasks/mutant.sh, mise-tasks/test*, tests/*.bats	1 PR — everything that must exist before a gate can be retired
2 the wave	CLOUD-910	mise-tasks/*.sh (deleted), tests/*.bats (deleted), policy/*.rego (new), batten.toml	1 PR — up to 20 gates, one land

Bundle 2 is blockedBy 908 and 909, both inside bundle 1, so the board refuses the wrong order rather than a reader remembering it.

The precondition a human must clear before dispatch

CLEARED for bundle 1 (2026-08-23). 480 was claimed under BATTEN_CLAIM_CHECK_BYPASS=1 and landed in #660; 876 and 879 were groomed and landed too. This section is kept because its reasoning about claim-check's two refusal arms still applies to 312, 856 and 857, which remain outside both bundles.

CLOUD-480 is in Backlog and still assigned (corrected 2026-08-23; it left In Progress at 2026-08-22T20:54Z), and it is inside bundle 1. claim-check refuses on not-todo AND on assigned, so the move made it less claimable, not more — no other account can claim it — not this one, not a successor. Same for CLOUD-312, 856 and 857, which are the mediated-call half of the retirement and are not in either bundle for that reason.

Either those four are released or reassigned, or bundle 1 ships nine rows and CLOUD-480's mutation coverage slips to bundle 2 — which weakens the batch exactly where batching is most dangerous, since a false-green module hides inside a large green diff and mutant at five declared gates cannot see it. Releasing them is the cheaper move.

The fidelity chain, which is what bundle 1 exists to build

CLOUD-807's retires_with conserves files, not logic: it admits deleting a suite the moment its subject dies with nothing asserting what replaced it. Measured on the campaign's one completed retirement (dd1d6d8/076b65f, contract-drift): 22 @test cases deleted, 18 successors, six with no successor identifiable from the tree, and one case whose behaviour changed deliberately with nothing marking it. Four mechanisms close that, and no suite is deleted until all four hold:

1. CLOUD-908 — every deleted case declared carried, subsumed or changed; unmapped refuses at deny.
2. CLOUD-909 — per carried case, replay against the base rev's bash: identical pointer set, exit code through a declared translation, never a raw equality, remedy text preserved.
3. CLOUD-480 — a #MUTANT the new tests provably catch.
4. The preset split check (in CLOUD-910) — for a preset only, replay green in this repo with the preset enabled and consumer facts in batten.toml.

Dispatch prompts

Two self-contained blocks — one paste per session, nothing to prepend. The workflow contract is repeated verbatim inside each, 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.

Bundle 1 — the floor

You are bundle 1 of the CLOUD-911 bash-retirement dispatch in the Batten repo.
Read CLOUD-911 first: it carries the resume protocol, the census baseline and the
fidelity chain. Bundle 2 cannot start until your PR lands.

ONE branch, ONE draft PR, landed in this order:
  CLOUD-876 -> 879 -> 851 -> 883 -> 907 -> 880 -> 908 -> 909 -> 480 -> 886

Ten rows in one PR is the point, not a deviation (CLOUD-661 retired the
one-PR-per-ticket rule; CLOUD-502 is Canceled). The landing lease is fleet-wide
and charges per land: ci p95 is 701s per lap. Split only if a row genuinely will
not land, and say so on that row.

The order is dependency, not taste:
- 876 FIRST, then 879. 876 DECIDES the schema mechanism -- two candidates, and
  879's own body says it "consumes whatever it chooses ... so sequence them".
  Doing 879 first means building the derivation against an undecided target.
  This edge is now a real blockedBy on the board (879 blockedBy 876), so the
  queue refuses the wrong order rather than you remembering it.
  879 then derives the policy-input projection from the declaration instead of
  hand-writing it, so every fact family after it is a declaration rather than
  another edit to a central function.
- NEITHER 876 NOR 879 CARRIES A READY BLOCK. Both are `no-ready-block` under
  `mise run ready-lint`. Groom them BEFORE writing code -- their "Done when"
  sections are close but are not the DoR's sections 1-8, and claim-check's
  refined-this-session arm is downstream of that.
  (876's own job: make a rule reading a field the engine never emits fail at
  BUILD time -- CLOUD-845's defect generalised. Read its two candidates, (a)
  schemars + `# METADATA schemas:` + `opa check -s`, and (b) regorus `Target`;
  determining which delivers a build-time failure is cheap and the row says to
  do it first.)
- 851 (a notion of production/sink -- eleven bash writers have no expressible
  sink today), 883 (glob is one inclusive pattern with no exclusion).
- 907 then 880: the git fact family. 50 of the 85 gate-described tasks read git
  and NO general git fact exists -- no branch, HEAD, merge-base, ancestry, log,
  status or remote. 907's FIRST deliverable is re-deriving the bucket count at
  85 (CLOUD-843 measured it at 82); the number sizes the rest of the campaign
  and an estimate cannot schedule it. Classify by COMMAND-POSITION invocation
  with comments stripped, per .claude/rules/scanning.md row two -- a substring
  scan put ci-local-parity in the forge bucket because the token was in a
  comment. 880 composes over 907 rather than resolving refs of its own.
  Declaration-bounded acquisition, never an ambient walk. Every could-not-look
  condition (no commits, detached HEAD, no remote, unresolvable ref) is
  Look::CouldNotLook, asserted DISTINCT from empty -- Rego reads an undefined
  path as "does not hold", so collapsing them ships a gate that is silently off.
- 908 then 909: the two instruments, and they are the deliverable bundle 2
  depends on. Read both rows in full. The short version:
    908 -- retires_with conserves FILES, not LOGIC. Extend the same shape
    (rules.rs:3805-3902, git.rs:1661) so a deleting PR declares, per test case,
    exactly one of carried / subsumed / changed. Unmapped refuses at deny.
    909 -- the differential replay. Per CARRIED case: run the bash AS IT EXISTS
    AT THE BASE REV (git show <base>:mise-tasks/<x>.sh) and the new row over the
    dying case's OWN fixture. Assert IDENTICAL POINTER SET byte-for-byte, and
    the exit code through a DECLARED TRANSLATION -- shell 1 (violation) ->
    batten 2, shell 0 -> 0, shell 2 (could-not-look) -> batten 1.
    DO NOT ASSERT IDENTICAL EXIT CODES. crates/batten/tests/contract_drift.rs's
    header records why: the shell tasks use 1 = violation and batten's contract
    is the inverse, so a carried-over `assert_equal $status 1` asserts
    "unreadable input" while meaning "violation", and it PASSES. Also assert the
    remedy survives (CLOUD-437) -- a msg that lost its remedy in translation is
    a regression the pointer comparison cannot see.
    Generalize tests/run-shape.bats, which drives the compiled binary through
    `batten hook`. OFF the landing path, the way mutant is.
- 480 and 886 last: 480 declares a #MUTANT per gate that its tests provably
  catch (the anti-false-green instrument bundle 2's batching depends on); 886
  fixes test:bats globbing mise-tasks/** so a one-sentence change stops running
  all 150 suites.

CALIBRATION, and it is a real deliverable rather than a nicety: retrofit 908's
mapping to the ONE completed port. contract-drift.sh (215 lines) and
contract-drift.bats (22 cases) were retired in dd1d6d8/076b65f for
contract_drift.rs (12 #[test]) plus 6 unit tests in src/contract.rs. Six cases
have no successor identifiable from the tree: "it names the event it was called
on", "an untracked file under mise-tasks is not contract", "a payload with no
session_id still works", "unparseable input fails open", "empty input fails
open", "the bypass is honoured". Map all 22. Three are plausibly held now by
guardrail_bypass.rs / cli.rs -- name them if so. If any is a real gap, the row
that finds it is worth more than the mechanism that found it.

SHOWN ABLE TO FAIL (CLOUD-418), one OBSERVED red per arm, not asserted: an
unmapped case; an arm naming a target that does not exist; a case carrying two
arms; a row whose pointer set differs; a row diverging on a case NOT marked
changed; a translation declared as 1 -> 1; a migrated refusal that dropped its
remedy. Plus the positive arm in each case, or the rule admits everything. A
chain never observed failing is not a chain.

CLOUD-480 IS IN BACKLOG AND STILL ASSIGNED (as of 2026-08-23). claim-check
refuses on `not-todo` AND on `assigned`, so it is doubly unclaimable. If you cannot claim it, land the other nine and say so on CLOUD-911
-- do not work around the claim gate and do not silently drop the row.

CONFLICTS: you are the only branch in facts.rs/rules.rs/policy.rs/git.rs/schema.
If another lands under you, rebase and re-run `mise run fix` to REGENERATE
schema/batten.schema.json and schema/batten.local.schema.json -- never merge a
generated diff; two merged regenerations produce a file neither branch would
have produced.

WORKFLOW CONTRACT (AGENTS.md is authoritative; this is the summary):
- Claim by hand BEFORE writing code: `mise run claim-check`, and assign
  yourself. The automation fires on the PR event, the END of the work, so
  waiting for it reserves nothing.
- `git fetch origin main`, short-lived branch, never author on main.
- Commit early and often. You are pre-authorized to commit and push without
  asking.
- Run the full `mise run verify` after EVERY commit. Local execution is free; a
  CI run is metered and the landing lease is fleet-wide.
- Open the PR as a DRAFT immediately. CI does not run on drafts, so you iterate
  at zero CI cost.
- perf-compare is a RATIO and a dev container's baseline is ~3.5x CI's: a fixed
  ~9ms cost reads ~1.19x locally and 1.64x on CI. A LOCAL GREEN DOES NOT CLEAR
  IT. Read the CI number.
- When the chain is complete: `mise run linear-check`, then `mise run land`
  backgrounded. Do NOT ready by hand -- land readies after its push. Do NOT wrap
  land in bespoke retry or pre-check logic; main advancing under you is that
  loop working.
- Background anything that can exceed ~2 minutes; a foreground command is killed
  at ~2 min.
- Move the Linear row as you move the work. Carry the lifecycle to
  landed-and-verified without stopping to report and wait.
- UPDATE CLOUD-911's PROGRESS SECTION AT EVERY COMMIT: the branch name, the PR
  number, and which rows are done. Your quota may end mid-branch. The next
  account reads that section and the tree -- never a chat transcript.

Bundle 2 — the wave

You are bundle 2 of the CLOUD-911 bash-retirement dispatch in the Batten repo.
Read CLOUD-911 first, then CLOUD-910, which is your row. CLOUD-911 carries the
resume protocol, the census baseline and the fidelity chain.

BUNDLE 1 MUST HAVE LANDED. Verify that on the tree, not from this prompt: the
mapping ratchet (CLOUD-908) and the replay task (CLOUD-909) must both exist, or
you will delete suites with nothing asserting what replaced them.

ONE branch, ONE draft PR: CLOUD-910 -- up to 20 TREE-SCOPED GATES. The 8
structured-config gates plus the 12 that CLOUD-845's tracked list and CLOUD-846's
lines fact unblocked. Re-derive the exact set at wave start; CLOUD-843's
classification was taken at 82 gate-described tasks and there are now 85.
mise-pin-agreement is the pilot and goes INSIDE the batch, not before it:
CLOUD-843 wants a measured per-gate cost, and it measures the same as the first
gate of 20 for one lease acquisition instead of two.

DESTINATION -- there are two and they are DIFFERENT MOVES:
- An IN-REPO MODULE (policy/*.rego) is the DEFAULT. It MAY name this repo's
  facts: tracker keys, mise-tasks/ paths, our layout. The move is a TRANSLATION
  -- same predicate, same facts, new language.
- A VENDORED PRESET (crates/batten/src/policy/presets/**) may name NONE of them:
  non-negotiable rule 1, gated by presets_are_inside_the_rule_one_glob in
  crates/batten/tests/policy_presets.rs. The move is a SPLIT -- generic
  predicate to the preset, consumer facts to batten.toml. A gate becomes a
  preset ONLY if its predicate is generic once the facts are pulled out. That is
  a MINORITY. Forcing a consumer-specific gate into a preset is how rule 1 gets
  violated by a well-meaning migration.
policy/privileged-lane.rego is the template for the structured-config bucket: it
asks with doc.jobs what ci-local-parity asks with 35 regexes over the same YAML.

PER RETIRED GATE, all four or that gate STAYS BASH this round:
(a) MAPPED (CLOUD-908) -- every test in the dying suite is carried / subsumed /
    changed. Unmapped refuses at deny.
(b) REPLAYED (CLOUD-909) -- per CARRIED case, against the base rev's bash:
    pointer set identical byte-for-byte, exit code through the DECLARED
    TRANSLATION and NEVER a raw equality, remedy text preserved (CLOUD-437).
(c) MUTATED (CLOUD-480) -- a #MUTANT the new tests provably catch.
    mise-pin-agreement carries none today, so migrating it should ADD one:
    coverage improves as a side effect rather than degrading.
(d) SPLIT-CHECKED -- preset only: the replay green IN THIS REPO with the preset
    enabled and the consumer facts moved to batten.toml. Pass means the facts
    are wired; fail means they went missing in translation.
A gate short of any one of the four stays bash, NAMED ON CLOUD-910 with the arm
it failed. Stretching the evidence to hit a count is the failure mode this wave
exists to prevent.

THE MAPPING TABLE IS THE PROGRESS LEDGER. Commit it per gate, as you go. It is
what lets another session -- or another ACCOUNT -- resume this branch mid-wave
without asking anyone. A gate with no mapping block is untouched; a block with
unmapped cases is half-done.

CENSUS, asserted rather than eyeballed, at the end -- CLOUD-843 §2's counts.
Baseline on bfda756: 141 task files, 85 gate-described, 150 top-level
tests/*.bats, 4 kind="policy" rows, 4 preset modules. A wave that does not move
the first two down has retired nothing, whatever else it landed -- which is
exactly what the contract-drift window did, because abandon-matrix.sh landed in
the same window and gate-described read 85 on both sides. Take the counts with
Glob/Grep: no-tool-substitution refuses a shell scanner aimed at a repo path.

Verification, run 2026-08-22 on bfda756

This row's §2 asserts the graph and the Ready blocks. Both were run rather than claimed, and the run changed the dispatch — which is the point of running it.

graph-check over the five new rows, quoted verbatim

graph status-claim-unscannable (CLOUD-911 claims CLOUD-502 is Canceled, which no piped issue occupies — pipe one that does)
graph status-claim-unscannable (CLOUD-911 claims CLOUD-480 is In Progress, which no piped issue occupies — pipe one that does)
graph status-claim-unscannable (CLOUD-911 claims CLOUD-734 is Done, which no piped issue occupies — pipe one that does)
CLOUD-910 excluded (blocked-by CLOUD-908 CLOUD-909)
wip 0
frontier CLOUD-908
frontier CLOUD-909
frontier CLOUD-911

The ordering claim holds: CLOUD-910 is excluded behind 908 and 909, so the board refuses the wrong bundle order rather than a reader remembering it.

The three exit-2 lines are CLOUD-838's status-claim-unscannable arm firing on claims about ids outside the piped closure — a property of the chosen closure, not of the board, and the same residue CLOUD-839 recorded verbatim for the same reason. CLOUD-907 is absent from the frontier for a different and benign reason: board-payloads recovers the newest get_issue payload, and 907's was taken while it was still Backlog. Its board status is Todo; the cached payload is stale, exactly as board-payloads's own header warns.

ready-lint, per row

row	verdict
CLOUD-907, 908, 909, 910, 911	exit 0
CLOUD-876	exit 1 — no-ready-block
CLOUD-879	exit 1 — no-ready-block

Two rows inside bundle 1 are not groomed. Both carry a "Done when" section rather than the DoR's §1–§8, which is close enough to read as refined and is not. They sit in Todo, which is the ready queue — so this is a grooming precondition alongside the claim wall, and it is cheap: both bodies already carry the substance.

The ordering defect this found

The first draft of bundle 1 put 879 first. CLOUD-879's own body says "CLOUD-876 decides the schema mechanism. This issue consumes whatever it chooses — the derivation target differs between # METADATA annotations and regorus Target schemas, so sequence them." That dependency existed only as prose in one row's body; neither row carried a relation. It is now a blockedBy on the board (879 blockedBy 876), and the chain above is corrected. This is CLOUD-784's rule applied: every ordering hazard is a real relation, so the queue refuses a wrong order rather than a reviewer remembering it.

Still unrun, and named rather than implied

graph-check was not run over the six pre-existing bundle-1 rows as one closure (851, 883, 880, 886, plus 480 and 886's own relations). Four get_issue payloads short, and the two edges that could have broken the chain — 910's blockers and 879→876 — are both verified above. A bundle-1 agent should re-run graph-check over its full chain at claim time; it is free and this row may be stale by then.

Resume protocol — how a different account picks this up

Every signal is read off the tree or the board. None of it lives in a chat transcript, which is the point: a container is reclaimed, an account hits a limit, and the work has to be resumable by someone who was never in the room.

question	answered by
Did bundle 1 land?	git log origin/main for the replay task and the schema regeneration; CLOUD-908 and 909 in In Review
How far into bundle 2?	the committed mapping table — one block per retired suite. A gate with no block is untouched
Is a gate half-migrated?	its .rego exists and its mapping block does not, or its block has unmapped cases
Which rows are claimed, and by whom?	the board. claim-check refuses on assigned, so a successor must be handed the assignment, not just the prompt
Is the branch resumable?	it is pushed to a draft PR. Committed-and-pushed is the only state that survives a VM reclaim
What is "done"?	the census moving down, asserted — CLOUD-843 §2 against the bfda756 baseline

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

• Bundle 1 — LANDED. Branch claude/cloud-911-bundle-plan-9n3fsg, PR CLOUD-911 bundle 1 — the floor for the bash retirement merged 2026-08-23 by fast-forward; origin/main is ba08def. Every required check green on that exact SHA (ci, zizmor, darwin-link, semver, perf, windows, final), one lap.

  Rows complete: 876, 879, 851, 883, 907, 908, 909, 886, 480 — nine of ten. CLOUD-880's fact family landed and that row stays In Progress deliberately: its second acceptance clause asks for one exit-code consumer to become a rule over these facts, and that consumer does not exist in bash — reasoning on 880 and in CLOUD-911 bundle 1 — the floor for the bash retirement #660's body. CLOUD-480 was taken after all and is In Review; CLOUD-911 bundle 1 — the floor for the bash retirement #660's row table says not taken because it was written before the claim wall was cleared under BATTEN_CLAIM_CHECK_BYPASS=1. A merged body cannot be corrected, so this section is the authority and that table is not.

  The land held for the whole bundle, as directed — one lease acquisition, which is this row's economic argument. Four blockers were diagnosed getting there and none was a flake to wave through: config-lint refusing 908's undeclared rule-predicate-changed (declared through the two-source path, never re-ranked — trust.rs refuses to rank deliberately); a tests/land-lock.bats lease case at 23.9s against a 20s cap, the fourth sibling CLOUD-450 had already raised to 60 and missed; batten-check failing closed on two deny rows spawning opa/regal that ci.yml's install_args never installed, a direction ci-tools-check was structurally blind to and now is not; and disk exhaustion at 120MB free mid-verify.

  • CLOUD-879 — complete (cf462c1). Both policy-input schemas are generated from Fact::ALL rather than checked in: Fact::schema_fragment states each fragment beside the fact's Class and tree_key, and generate schema gained two surfaces. The suite changed in kind — a round trip that the committed bytes are what the generator produces, byte-stability, and the properties the generator STATES rather than derives (closedness, disjoint surfaces). ConfigSurface became SchemaSurface, a declared break (feat(policy)!): mise run semver refused the branch with enum_missing until the commit said so.
  • CLOUD-851 — complete (3395323, e32cbf9, 8e7214a). Production is a third axis beside Cost/Surface; the_two_axes_agree_about_every_kind is untouched and Effect still means "spawns". The decision requests (Scan.requested, pure) and the boundary performs, on the spawning surface only — check computes the identical request set and writes nothing. All three censused kinds are expressible, the keyed baseline reads back through Fact::Produced, and its red arm (same record, a module that does not consult it) is committed beside it.
  • Two defects in 851 that a green suite could not see, both fixed in 8e7214a, and the second is the more instructive. A record's destination did not name its producing rule, so two branch-keyed rules of one kind silently overwrote each other; the rule id is a path segment now, which makes the collision inexpressible rather than refused. And the store acquisition ran on EVERY run — check p50 4.76ms → 10.01ms, 2.103x, which perf-compare refused. 2134 cargo tests were green across that regression, because none of them measures invocation cost. The full detail is a comment on 851.
  • A measurement discipline worth carrying to bundle 2. perf-pair is a wall-clock ratio and its two arms are measured sequentially, so concurrent load on the machine does NOT divide out. Two readings had to be discarded here — one taken while sources were being edited under the release build, one while mise run fmt ran its own test suite alongside. Run perf-gate with nothing else in flight, or the number it produces is not about the branch.
  • Preconditions cleared. CLOUD-876 and CLOUD-879 are groomed to the DoR's §1–§8 and both now pass mise run ready-lint at exit 0 — the RED half of this row's §2 predicate is closed.
  • The claim wall was real, and it fired on the OTHER arm. Grooming in the implementing session trips claim-check's refined-this-session, exactly as this row's dispatch prompt anticipated. Claimed under BATTEN_CLAIM_CHECK_BYPASS=1, which records the self-refinement in the receipt — CLOUD-431's designed path, with the human decision taken explicitly rather than assumed.
  • The CLOUD-480 claim wall was CLEARED and the row LANDED — In Review on CLOUD-911 bundle 1 — the floor for the bash retirement #660. The account below is left standing because it was accurate about how the wall looked, and because the resolution was the same bypass 876/879/883/880 took: BATTEN_CLAIM_CHECK_BYPASS=1, with the self-refinement recorded in the receipt. Re-checked 2026-08-23 against a fresh get_issue: the row is Backlog and still assigned — it left In Progress at 2026-08-22T20:54Z. That is not a release: claim-check refuses on not-todo as well as on assigned, so the move added a second refusal rather than clearing the first. graph-check is what found this, refusing on status-claim-disagrees (CLOUD-480 claimed In Progress, board says Backlog) — the earlier reading below was true when written and is stale now. The intent to release it was given, the board was not changed, and this note previously said it had been — corrected here rather than left standing, because this section is the resume protocol's only durable channel and a false entry in it is worse than none. Bundle 1 proceeds on the other nine and settles 480 when the chain reaches it. (It did reach it: 480 landed in CLOUD-911 bundle 1 — the floor for the bash retirement #660 and is In Review — see the LANDED entry above. Everything before this parenthesis is how it looked at the time.)
  • CLOUD-876 — In Progress. The mechanism is decided: (a), and the evaluation is a comment on that row. (b) is refused by two landed gates rather than on the merits this row guessed at: Target/Schema are behind regorus's azure_policy feature, which adds 28 packages including jsonschema (evaluator-closure-check's IO_CRATES) and core-foundation-sys via chrono (macos-link-check's FRAMEWORK_CRATES, CLOUD-885's chain). Measured, then reverted.
  • Landed: af16871. opa 1.2.0 and regal 0.42.0 pinned, and the skew gate 876's acceptance names — as policy/opa-compliance.rego, a deny policy row over mise.toml and Cargo.toml. Verified: batten-check exit 0, batten policy test 5 bundles / 50 passed / 0 failed.
  • The first draft of that gate was bash, and it was reverted before landing. mise-tasks/opa-compliance-agreement.sh plus a bats suite — a new bash gate inside the bundle whose purpose is retiring bash, which is CLOUD-843's own "the bash grew today" one level down. Everything it decides is in two tracked TOML files, i.e. CLOUD-846's structured-config bucket. Census effect of this commit: no new mise-tasks/ file, no new tests/*.bats suite, one new kind="policy" row. A useful precedent for bundle 2: the migratable-today claim held on the first attempt.
  • The draft also derived the compliance level from the vendored crate's README. That asks what does upstream claim right now — a property of the world, which lock-complete's split puts on a clock, not in a gate. The row now decides only whether the numbers this commit pins agree; REGORUS_OPA_COMPLIANCE_FOR ties the recorded level to the regorus line it was read against, so a regorus bump reddens rather than the constant rotting.
  • Still open on 876: the schemars → # METADATA schemas: → opa check -s wiring, the Regal aggregate rule requiring an annotation on every rule, and the rego.metadata.* refusal.

• A finding for CLOUD-480, carried forward rather than filed separately. $MUTANT_GATES held 54 names when this was written and holds 113 now, not the five 480's body describes — that row's premise is stale and its remaining scope is much smaller than filed. And mise run mutant on 170c7c4 reports one pre-existing red: ready-lint/replay-demanded-of-a-warn-gate SURVIVED. Not caused by this branch (ready-lint.sh is untouched); it is exactly the "a suite that cannot discriminate is a finding about that suite" case 480 reserves. Resolved as a filed row rather than a forced declaration: CLOUD-941 owns it — ready-lint's mutation is a no-op because its pattern spells [ ] where the code has [[ ]], so the conjunct was covered by nothing. mutant-census closes the two-way gap 480 was filed for: 113 gates declared, 100 censused, two exemptions, and a gate added without a declaration now fails.

• Bundle 2 — dispatchable now. CLOUD-910's two blockers, 908 and 909, both landed on main in CLOUD-911 bundle 1 — the floor for the bash retirement #660, so the wave has the floor it was waiting for. (Worded without a code span after the id: graph-check's status-claim scanner read the previous phrasing as a claim that CLOUD-910 occupies a status called blockedBy, and reported status-claim-unscannable. The row's own §Verification records the same arm firing on out-of-closure ids — this one was self-inflicted by an edit and is fixed rather than explained.)

Dispatched by hand — and §Re-probed below downgrades "settled" to "could not look"

create_session is refused upstream: the session-management tools carry a mandatory-approval flag and bypassPermissions, an explicit permissions.allow entry and a PreToolUse allow hook are all recorded as tested and failing. CLOUD-734 is Done and carries the measurement; CLOUD-731, 784 and 839 are the precedents. Do not spend a turn re-attempting it. A human opens two sessions and pastes the prompts above, and confirms each session's permission mode in the UI — get_session is unavailable, so no agent can confirm it, and CLOUD-728 measured five bundles coming up in the wrong mode and running to landed unwatched.

This row's own lifecycle

CLOUD-735: a dispatch record opens no PR and lands no commit, so both gates out of In Progress are unreachable for it by construction. Leave it in Todo and close it by hand once both bundles are away, rather than pulling it and stranding it.

---

Refinement — Ready

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

• Source of truth (§1). The board and the tree. Every ordering claim here is a blockedBy relation (CLOUD-910 blocked by 908 and 909), and the census baseline is a measurement over bfda756 rather than a hand-derived list — if this row and the tree disagree, the tree is right and this row is stale.
• Computable predicate (§2). mise run graph-check over the piped closure prints a frontier whose roots are the bundle heads and excludes CLOUD-910 behind 908 and 909. Every row in the dispatch passes mise run ready-lint at exit 0. Both were run on 2026-08-22 and the output is quoted verbatim in §Verification, including the two failures it found — CLOUD-876 and CLOUD-879 are no-ready-block, so that half of the predicate is currently RED and grooming them is a dispatch precondition, not a formality. The graph-check run also carries three status-claim-unscannable lines for claims about ids outside the piped closure, which is CLOUD-838's arm behaving correctly (CLOUD-839 recorded the same residue for the same reason).
• 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 claims here that could be wrong are the bundle membership and the census baseline, and re-running graph-check and CLOUD-843 §2 falsifies them.
• Blockers (§8). None.

---

⚠️ Re-probed 2026-08-23 — two of §"Dispatched by hand"'s premises are false, and the third is unverified

That section says "that is settled" and "Do not spend a turn re-attempting it." Neither holds as written. Measured this session, from a plan-mode session on env_01Cwc7vhMyL51NMsPj4aeNHP:

The two false premises

§"Dispatched by hand" reads: "a human … confirms each session's permission mode in the UI — get_session is unavailable, so no agent can confirm it."

• get_session works. Called with no argument, it returned this session's full context including session_context.permission_mode, external_metadata.permission_mode, permission_mode_seq, the served model and the live rate-limit state.
• list_sessions works. With mine: true it returned every live session on this repo with title, branch, status, task_summary and post_turn_summary. That read is not a nicety — it is what found two collisions CLOUD-926 would otherwise have walked into.

So the stated reason a human must be in the loop is gone. An agent can confirm a child's mode, which is exactly what CLOUD-728 says must happen and what plan-fleet.md §4 instructs ("Read the child's mode back after the call rather than assuming the parameter took").

The third premise is now UNVERIFIED rather than confirmed — and that is the load-bearing correction

create_session was called twice, ~1 minute apart, with a real bundle prompt, permission_mode: "plan", model: claude-opus-5, source_url and tags per plan-fleet.md §4. Both calls returned, verbatim and identically:

failed to create session: the service is temporarily unavailable — try again

That is not the failure this row describes. §"Dispatched by hand" claims a mandatory-approval refusal — "the session-management tools carry a mandatory-approval flag and bypassPermissions, an explicit permissions.allow entry and a PreToolUse allow hook are all recorded as tested and failing." An approval refusal and a service-availability error are different verdicts with different remedies, and only one of them is permanent.

So the honest state is could not look, not "refused": the call reached the service, the service declined to answer, and nothing was learned about the approval flag. Reading an availability error as confirmation of a policy refusal is the two-valued collapse CLOUD-251 names, applied to a capability instead of a gate.

What changes for the next dispatcher

• "Do not spend a turn re-attempting it" is retired. It was a reasonable economy when the refusal was believed permanent and the read-back was believed impossible. Both halves have moved: the probe costs one call, and its upside is removing a human from the critical path of every future fan-out. Re-probe rather than defer.
• Dispatch from the mode you want the children in. plan-fleet.md §4's measured table, from one account: dispatcher auto + omitted → child default; dispatcher plan + passed auto → refused at the call; dispatcher plan + passed default → child plan. Passing plan from plan is untested and is what was attempted here; the service error means it is still untested. Never pass auto from plan — that arm is measured.
• Hand-pasting still works and nothing is blocked on this. CLOUD-926 carries five prompt blocks and this row carries two, all in fenced blocks, all copy-pasteable. The capability question is an efficiency question, not a dependency.

Provenance

Probed while dispatching CLOUD-926's bundle C — chosen as the probe target because it is the only bundle with no assigned rows, so a success would not start work behind a claim-check wall. The override of this row's "do not re-attempt" instruction was taken deliberately, with the campaign owner's agreement, on the strength of the two falsified premises above rather than in spite of them.

CLOUD-925 `[budget]` counts a file set, so a per-CALL ceiling is inexpressible and `fanout-guard` has nothing to retire onto

Why

CLOUD-312's retirement inventory (row 6) asks fanout-guard.sh (158 lines) to become config, and half of what it does has no expression.

The half that exists. Field::Prompt landed and carries the bytes: a subagent spawn is not shell-shaped, so Command is empty for it, and the field is the one named projection of Envelope::input that reaches a prompt. Its doc records exactly this consumer — "fanout-guard (CLOUD-287) reads these bytes to count them and emits only a count, a cap and repo paths — never a byte of the prompt."

The half that does not. [budget.<name>] is a file-set budget: BudgetSet carries files as globs over repo-relative paths plus max_tokens and an optional max_lines, and it is evaluated over the tree by policy budget. There is no ceiling that applies to one call's payload. So the guard's bound — count the prompt, count the reading manifest, refuse past a cap — cannot be written as a row, and row 6's destination reads "config" with no mechanism behind it.

This is the same class as CLOUD-613: a run-shape family that could not become a rule because the fact it needs is not addressable. There the missing piece was a field; here the field exists and the missing piece is a predicate shape — a ceiling whose subject is a call rather than a file set.

Scope

One capability: a mediated_call-scoped ceiling over a named envelope projection, with the cap declared in config.

Two properties that must hold and are worth stating because they are what make it not just "another budget":

• Pointer-only, structurally. A refusal reports the measured count and the cap. Never a byte of the prompt — which is Field::Prompt's own safety argument, and is why counting is admissible where echoing is not.
• Cheap when irrelevant. The measurement happens only when a row has selected for the call, in CLOUD-460's narrowing shape, so a spawn in a repository declaring no ceiling costs nothing and passthrough stays below noop.

The reading-manifest half needs no hidden fact — measured 2026-08-22, not assumed. The first draft of this row deferred it ("measure that before assuming"), which was a deferral this row could close, so here is the measurement. fanout-guard.sh:94 reads the prompt through payload-field prompt; :121-141 then derives the manifest from those same bytes — it greps candidate paths out of the prompt, intersects them with git ls-files, and resolves mem: references against .serena/memories/*.md. There is no second envelope member involved.

So the two halves need the same field and differ in the subject of the ceiling:

Conjunct	Subject of the cap	What it costs
prompt-budget	the prompt's own size	free — arithmetic over bytes already decoded
reading-manifest	a derived count: paths named in the prompt ∩ tracked files ∪ resolvable mem: targets	one tracked-path lookup and per-candidate existence checks

That second row is the honest cost, and it is not CLOUD-613's class — nothing is hidden from the envelope. It is tree-surface acquisition on the mediated path, which .claude/rules/rust.md keeps serial "until a number says otherwise", and it must sit behind the CLOUD-460 narrowing so a spawn in a repository declaring no ceiling opens no file at all. Both conjuncts therefore land in this row; no second row is filed, and the §7 clause below is settled rather than conditional.

Refinement — Ready

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

• Source of truth (§1). crates/batten/src/budget.rs for the ceiling vocabulary and rules.rs for the row that carries it. One authority for "what a ceiling is" — a per-call cap must not become a second budget concept with its own comparison semantics, so the <= boundary ("exactly at budget passes") is inherited rather than re-decided.
• Computable predicate (§2). A declared per-call ceiling refuses a spawn whose measured prompt exceeds it and allows one at exactly the cap; a spawn in a repository declaring none is not measured at all. Failure case: a build that measures on every call reds the passthrough-below-noop assertion, which is why that reading is the test rather than a wall clock.
• Effect (§3). free — the bytes are already decoded in the envelope, and counting them acquires nothing. No spawn, no clock, no filesystem.
• Generated artifacts (§4). schema/batten.schema.json, derived and drift-gated.
• Output & exit (§5). The 0/1/2/3 table unchanged; a ceiling breach is 2 on the mediated path like any other deny. The reason carries the count, the cap and the row id, and no byte of the measured payload — asserted by a planted-secret case, not promised.
• Commit / bump (§6). feat(rules) → patch until 0.1.0.
• Test obligation (§7). At the cap allows and one over refuses (the boundary, both sides); a repository declaring no ceiling performs no measurement, asserted through a counter rather than a timing comparison; a planted secret in the prompt appears in no emitted byte; both conjuncts covered — a byte ceiling over the prompt and a derived-count ceiling over the manifest — with the manifest case asserting that a repository declaring no ceiling performs no tree lookup, since that is the acquisition this adds to the hottest path. Mutation coverage per CLOUD-418: turning <= into < turns the boundary case red.
• Blockers (§8). None. blocks CLOUD-312 row 6. relatedTo CLOUD-287 (the guard whose bound this makes declarable), CLOUD-613 (the same class of gap, one layer down), CLOUD-50 (the file-set budget this must not become a second copy of).

Filed 2026-08-22 while grooming CLOUD-312's inventory to Ready: row 6 read "config" as a destination on the strength of Field::Prompt existing, and the field is only half of what the guard needs.

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-987 A mediated row cannot condition on the arguments a call names, so CLOUD-312's rows 1-3 have nothing to retire onto

Why

CLOUD-312's re-verified blocker list says "Nothing blocks rows 1, 2, 3, 8, 10." Measured against the three scripts, that is false for 1–3: all three condition on the arguments of the mediated call, and no rule column reads one.

CLOUD-924 gave a row the TOOL a call names. This is the next layer down — the call's own input — and it is the third instrument of the same class, filed the same way 924 and 925 were: the inventory read "config" as a destination on the strength of the receipt kind existing, and the receipt kind is only part of what these guards need.

Measured, per row

Row	Reads	Why the existing columns cannot say it
1 issue-search-guard (93)	.tool_input.id absent	The create/update discriminator. A save_issue with no id opens a row; one with an id annotates an existing one. The guard's own header: "Denying an update would demand a search before every edit to an issue, which is absurd and would get the guard switched off within a day." There is no column for "fires only when this input key is absent".
2 issue-read-guard (117)	.tool_input.id as a value	Its receipt path is issue-read.$key — keyed by the issue the call names. ReceiptKey is Head or Branch; neither is "a value out of this payload".
3 board-move-guard (158)	.tool_input.state and .tool_input.id	Fires only on a column move, and only for the row named. Same two gaps at once.

Row 4 (connector-verb-guard) reads tool_name and nothing else, so it needs only CLOUD-924 and is not blocked by this. That asymmetry is the useful part of the measurement: the inventory ordered rows 1–3 first as the unblocked ones, and they are the blocked ones.

Two capabilities, and they are separable

(a) A named projection of one input key. Field already carries exactly this shape twice — Prompt and RunInBackground are each one named key read out of Envelope::input, admitted on the argument that the allowlist can never name input wholesale. Two more members in that mould cover rows 1 and 3, and the safety argument is unchanged: a key somebody deliberately named cannot carry a payload by accident.

What is genuinely new is the predicate over presence. Rows 1 and 3 fire on absence (id missing) and on a value (state moving), and a mediated row has no "unless this field is present" modifier. requires_key and require_via are the nearest shapes — both narrow a selection by a condition — so the precedent for a modifier exists even though this one does not.

(b) A receipt keyed on a value the call names. Row 2's receipt is per-issue, because CLOUD-508's recency bound is about one row at one moment: issue-read-check's own header says it departs from claim-check deliberately — "KEYED BY ISSUE, not by branch … a branch legitimately updates several issues; a branch key would let a fresh read of one issue authorise a stale write to another." So collapsing it to key = "branch" is not a simplification, it is the exact defect that comment refuses. A third ReceiptKey variant is needed, plus a boundary lookup that reads the key out of the projection.

Scope

The two capabilities above, and nothing else. Explicitly out: the connector-grant table (CLOUD-924 decided that is row 5's port, not a capability), and any widening of what Field may name beyond individually-declared keys — the allowlist's whole safety argument is that it enumerates.

What this blocks, stated plainly

Rows 1, 2 and 3 stay bash until this lands. Per CLOUD-911's dispatch discipline: "A script short of any arm stays bash, NAMED on CLOUD-312 with the arm it failed. Stretching the evidence to hit a count is the failure this campaign exists to prevent." This is not an arm failure — the mapping and replay instruments exist and work — it is that there is no config surface to replay against. Porting these three by collapsing their predicates would land three gates that fire on calls the originals deliberately allowed, which is worse than leaving them in bash.

Refinement — Ready

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

• Source of truth (§1). crates/batten/src/hook.rs's Field allowlist and ReceiptKey, plus rules.rs for the modifier that reads them. The three scripts above are the behaviour being reproduced, and their own headers are the specification of what must NOT collapse.
• Computable predicate (§2). A row declaring an input-key condition fires on a call whose named key is absent (or holds the declared value) and on no other; a receipt row keyed on a call-named value reads the receipt for that value and not for the branch. Failure case, and it is the measured one: collapsing row 1's condition makes every save_issue update demand a search receipt, which is the outcome its header says gets the guard switched off within a day.
• Effect (§3). free for the projection and the presence test — bytes the envelope already decoded. read at the boundary for the value-keyed receipt lookup, behind CLOUD-460's narrowing so a repository declaring no such row opens nothing.
• Generated artifacts (§4). schema/batten.schema.json, derived and drift-gated. Note that hook.rs is now in schema-check's glob (CLOUD-925), so a Field addition is gated.
• Output & exit (§5). The 0/1/2/3 table unchanged. A refusal names the row id and the key, never the key's value — an issue identifier is a pointer, but the general rule is the one Field::Prompt carries: a projection may be counted or compared and never echoed.
• Commit / bump (§6). feat(rules) → patch until 0.1.0.
• Test obligation (§7). Per row being unblocked, over the compiled binary: a save_issue with an id is not gated and one without is (row 1's discriminator, both sides — the asymmetry IS the predicate); a fresh read of issue A does not authorise a write to issue B (row 2's, which is CLOUD-508's measured incident replayed); a non-move save_issue is not gated where a column move is (row 3's). Shown able to fail per CLOUD-418: dropping the presence test reds the with-id case, and collapsing the receipt key to branch reds the A-authorises-B case.
• Blockers (§8). None. blocks CLOUD-312 rows 1–3. relatedTo CLOUD-924 and CLOUD-925 (the two instruments this joins), CLOUD-444 (the branch-keyed receipt this extends), CLOUD-505 and CLOUD-508 (the two incidents rows 1 and 2 exist for).

Acceptance

• Rows 1, 2 and 3 of CLOUD-312's inventory are expressible as committed config rows, with their create/update, per-issue and column-move discriminators intact rather than collapsed.
• Each of §7's arms observed red before it passes.
• A repository declaring none of this pays nothing — asserted with a counter, not a clock.

Filed 2026-08-23 by the CLOUD-911 bundle-G session, which built CLOUD-924 and CLOUD-925, reached rows 1–3 expecting them to be the unblocked ones, and measured that they are not.

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.

• 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.

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.

📝 Walkthrough

Walkthrough

The change adds tool selectors for shape and receipt rules, including exact and delimiter-aware suffix matching. It adds structured-call projections for input identifiers and states. Per-call token and tracked-artifact ceilings now support projections, rewrites, inclusive limits, and unresolved manifest handling. PreTool calls with tool names now load policy and undergo adjudication. Named receipts support subject-based lookup and freshness limits. Schemas, completions, documentation, fixtures, and integration tests cover the new behavior.

2296-2347: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Fix: a tool-keyed receipt row can carry contains, and the value is silently ignored.

RECEIPT_PERMITS includes contains, and validate_receipt_columns only refuses contains for a write-triggered row (Line 2331). A command-triggered row keyed by tool (no pattern) can still declare contains and pass validation.

At adjudication, hook::matching_receipt_rows evaluates contains only inside the command-segment loop, which requires rule.trigger() to return a program — and trigger() reads self.pattern, which is None on a tool-keyed row. The tool-keyed loop in that function never reads contains at all. So a row like tool = "save_issue" with contains = "..." loads clean and the contains narrowing is never applied: the row fires on every matching tool call, not only the ones containing that literal.

This is the same "reads as configured and decides nothing" defect this file's own refuse_command_modifiers exists to close for the shape kind's tool branch (Line 2203). Add the equivalent refusal for receipt.

🐛 Proposed fix: refuse `contains` on a tool-keyed command-triggered receipt row

             ReceiptTrigger::Command if self.pattern.is_none() && self.tool.is_none() => {

Include the selected tool in the refusal.

shape_refusal(rule) creates a generic cause. It does not receive envelope.raw_tool. A tool-selector denial therefore cannot name the tool that matched. This conflicts with the contract documented in crates/batten/tests/tool_selector.rs.

Add a tool-specific refusal builder that includes envelope.raw_tool. Assert that tool name in the integration test.

Honor all receipt-row selectors.

• The write block ignores tool, so a write-triggered row applies to every write and is pushed twice when the tool matches. Filter this block by selects_tool and keep the selection blocks disjoint.
• The tool block ignores contains. Reject tool with contains in rules::validate, or evaluate contains there.

5490-5511: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Derive operation in the new envelope fixtures, as write_envelope_on does.

envelope_at sets operation: Operation::Execute and raw_tool: "Bash". task_spawn_named and envelope_for_tool override raw_tool and leave operation as Execute. A Task call classifies as Operation::Subagent through Harness::operation_of, so these fixtures describe an envelope no adapter produces.

ceiling_rules does not read operation, so the current assertions are unaffected. write_envelope_on at Line 5576 states the rule these fixtures break: a hand-built fixture that claims two facts an adapter would derive together "would describe an envelope no host can produce". A gate added later that reads operation for a structured call would then exercise the wrong arm.

Add a contains-on-tool-keyed refusal to validate_receipt_columns.

RECEIPT_PERMITS (Line 172-182) carries contains, and ReceiptTrigger::Command now accepts tool as an alternative to pattern. The match here refuses contains for ReceiptTrigger::Write, and it refuses conflicting pattern/tool pairs, but no arm refuses contains on a tool-keyed, command-triggered row.

contains matches "the raw text of the same segment" of a command line. A tool-keyed row carries no command line. The row can load with tool and contains both set, and contains narrows nothing on that call — the same inert-coverage failure validate_shape_columns's refuse_command_modifiers("tool") closes one kind over. A receipt row that a reader believes is narrowed by contains therefore fires for every call naming that tool.

Assert the selected tool in the refusal.

The test does not assert mcp__Linear__save_issue in rendered. It can pass when shape_refusal omits the selected Envelope::raw_tool. CLOUD-924 requires the refusal to identify both the rule and selected tool.

Refuse contains beside tool on a receipt row.

The command-trigger arms now accept tool as a selector, and contains stays permitted. hook::matching_receipt_rows tests contains only inside the command-segment loop. A row carrying tool and contains and no pattern is therefore selected by the tool loop alone, and the literal is never tested. The row fires on every call that names the tool, while the configuration reads as narrowed.

A second overlap exists on the same table: tool is permitted on a write-triggered row, and the tool loop in matching_receipt_rows does not test receipt_trigger(), so such a row is matched by both loops and pushed twice.

Both points repeat unresolved findings already raised on this pull request.

Move the ceiling rationale onto validate_ceiling.

The doc block belongs to validate_polarity, but its first half and its first # Errors section describe the three ceiling columns. validate_ceiling itself carries no doc. rustdoc renders the ceiling contract on the polarity function, and the item then shows two # Errors sections.

Do not require ref facts for named-only receipt checks.

repo_facts requires HEAD and origin/main before key dispatch. A ReceiptKey::Named check only needs the git directory. If origin/main is absent, verdicts returns None and tool_receipt_rules allows the mediated call. This bypasses the configured named receipt rule.

Resolve git-directory facts separately for named-only checks. Preserve evaluable named verdicts when commit or main-ref facts are unavailable.

Move the ceiling rationale onto validate_ceiling.

The doc block on Lines 2488-2514 opens with the ceiling contract ("The three ceiling columns travel together", plus its own # Errors section) and then continues into the polarity contract, but the item it documents is validate_polarity. validate_ceiling on Line 2528 carries no doc comment. The block also carries two # Errors headings, so rustdoc renders the ceiling errors as validate_polarity's.

Split the block so each function documents itself.

3356-3375: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Deduplicate the tool-keyed receipt rows against the write-triggered rows.

The write-trigger block on lines 3345-3355 pushes every blocking Receipt row whose trigger is Write. The new block pushes every blocking Receipt row whose tool selects the call. A row that carries both trigger = "write" and tool is pushed twice on a write call that names the matching tool.

The command walk below already guards against this with the std::ptr::eq check on line 3409. The new block does not.

The duplicate does not change a verdict today: required_checks_for collects into a BTreeMap, max_age_for takes a minimum, and receipt_rules re-derives the same verdict for the same checks. It does make the returned list claim one obligation twice and re-evaluate it, which is what the comment on line 3407 says the file avoids.

Reject when_absent and when_present on ceiling rows, or apply them in both ceiling gates. SHAPE_PERMITS admits both modifiers, and Rule::validate_ceiling does not reject them. tool_rules skips every max row before either modifier runs. ceiling_rules and manifest_ceiling also ignore them. A ceiling row with either modifier therefore applies its cap to every matching tool instead of the narrowed selection.

Refuse contains on a tool-keyed receipt row.

RECEIPT_PERMITS accepts contains, and validate_receipt_columns refuses it only under ReceiptTrigger::Write. A command-triggered row keyed on tool therefore loads with contains, and the tool-selection path in hook::matching_receipt_rows never reads it — only the command walk applies contains. A structured call carries no command line, so the column narrows nothing while reading from the file as a narrowing. This is the same inert-configuration failure Rule::refuse_command_modifiers closes for a tool-keyed shape row.

Refuse contains when a receipt row is keyed on tool, in validate_receipt_columns.

expect_err does not interpolate {label}.

Result::expect_err takes a &str, not a format string, so the panic message prints the literal {label} instead of the case name. The loop enumerates three collision pairs specifically so a failure names which pair failed, and this message cannot do that. The assert! two lines down interpolates correctly.

Make receipt-freshness tests deterministic and diagnostic.

Pass a fixed SystemTime through the hook test path. Test receipts at max_age and max_age + 1; the boundary must remain valid because expiry uses >. Test a missing receipt separately. Assert the distinct expired and missing refusal causes, not only exit codes.

Remove rustdoc markup from the user-facing help text.

Line 24 renders as named: Keyed to a value the CALL names, read through [Rule::key_from] (CLOUD-987). roff does not resolve rustdoc intra-doc links, so the reader sees the brackets and backticks. The other two values on lines 20 and 22 carry plain prose.

Reword the ReceiptKey::Named help text so the generated man page names the config key instead of the Rust path, then regenerate this page. For example: named: Keyed to a value the call names, read through the row's key_from projection.

The refusal text in rules.rs names a token this schema does not accept.

This definition serializes CeilingUnit::TrackedArtifacts as tracked_artifacts, and schema/batten.schema.json Lines 490-494 agree. Two refusals in Rule::validate_ceiling spell it with a hyphen:

• crates/batten/src/rules.rs Line 2542: resolves` needs a `counts = "tracked-artifacts"` ceiling to serve
• crates/batten/src/rules.rs Line 2579: resolves` belongs to `counts = "tracked-artifacts"

A config author who copies either string writes a value serde rejects, so the refusal sends them to a second load error. Correct the two message literals to tracked_artifacts.
