CLOUD-312 row 1 retires, and the four prerequisites that made it possible - #680
Conversation
CLOUD-312 The engine is the pre-tool entry point; the shell guards retire behind it
WhyThe pre-commit layer and CI are already adjudicated by the engine reading the committed authority. The agent tool-call layer is not: Two implementations of one policy is two authorities for one fact, and the divergence is silent. A rule added to 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.

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
.batsfixtures 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 throughbatten hook, and the reply is byte-compared. - Exact deletion condition. The script, its
DECLAREDrow, 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. ADECLAREDrow naming a deleted command already fails aswiring-declaration-stale, and a command with no row already fails aswiring-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-racedis its worked instance. - CLOUD-461 — cleared, landed (In Review). The advisory channel is on
main, andcontract-driftretired 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:
- Exactly one Batten registration per supported event, per harness —
doctor hooksalready failshook-wiring-event-registered-n-timesandhook-wiring-event-unregistered, andhook-wiring-matcher-narrowson any matcher at all. - No unmanaged sibling command —
doctor hooksreportssiblings == 0andmerged == 0, or every remainder is aDECLAREDrow 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. - Every remaining dispatched behaviour is declared in committed configuration and validated from it — each surviving program is a
[[hook.handler]]row inbatten.tomlwith 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-990 Three board gates' remedies name a payload route that does not exist on a transcript-less host, and none names the capture store — measured, it cost a session an hour and two false blocker reports
Why
Three gates refuse a board write and each names the same remedy, and on a Claude Code remote (CCR) host that remedy is unreachable:
| gate | what its remedy says to do |
|---|---|
claim-needs-receipt |
"pipe the issue's get_issue payload to mise run claim-check" |
issue-read-guard |
"get_issue CLOUD-N … pipe that payload to: mise run issue-read-check" |
issue-search-guard |
"list_issues … pipe that payload to: mise run issue-search-check" |
None of the three says where the bytes come from, and the one place that answers it — mise-tasks/board-payloads.sh — reads ${BATTEN_TRANSCRIPT_FILE:-.claude/.transcript.jsonl}. A CCR container writes no transcript at all (checked /root/.claude, the projects directory, the session scratchpad), so board-payloads correctly answers "no readable transcript … This is not an empty harvest" and the remedy chain dead-ends.
board-payloads' own header is what makes this a trap rather than an inconvenience, because it forecloses the obvious workaround in the strongest terms — "a paraphrase into a gate payload is the forged-compliance shape CLOUD-526 measured seven times". So an agent reading the remedy honestly concludes the board cannot be written from this host, and it is wrong.
The route that works, and no remedy mentions it
CLOUD-919 landed exactly the missing source: every PostToolUse response is persisted as a local capture. The working recipe is three commands:
batten capture list
batten capture show <handle> --grep '"id":"CLOUD-930"' # find the right one
batten capture show <handle> --raw | mise run issue-read-check
Those bytes are the tracker's, never re-typed, so the forgery-resistance argument board-payloads makes is fully satisfied — this is a second honest source, not a loophole. --grep locates the handle and --raw emits verbatim. capture.rs's Stream::ToolResponse is the variant CLOUD-918 added for it.
Measured cost, this session
An agent carrying CLOUD-911's bundle 2 hit claim-needs-receipt, followed the remedy to board-payloads, got the absent-transcript refusal, and concluded the environment could not perform a board write. It then:
- reported a hard blocker to its human twice, asking for
BATTEN_GH_GUARD_BYPASS=1/BATTEN_ISSUE_READ_BYPASS=1; - documented an accidental fallback as if it were the only one — an MCP result large enough to spill to a tool-results file is pipeable, so whether a row was writable depended on the length of its description;
- discovered the circularity that it could not even file this finding, because
issue-search-guardwants the same bytes; - spent roughly an hour before a human said the capture spine existed.
Every step was a correct reading of the remedy text. That is CLOUD-871's thesis — remedy prose steers the agent — with a measurement attached, and it is a fleet-wide stall rather than one session's: every sibling dispatched into a CCR container meets the identical wall on its first claim.
Shape of the fix
Prose only, and deliberately so: the mechanism already exists and only the pointers to it are wrong.
board-payloads' absent-transcript error names the capture store as the other source, with the three-command recipe. It is already careful to say "this is not an empty harvest"; it should also say what to do next.- The three gate remedies name a source for the payload rather than assuming one — one clause, pointing at
board-payloadsorbatten capture show --raw. - Optionally, and larger, so it is not in this row's scope: teach
board-payloadsto read the capture store directly as a second source, so the recipe collapses back to one command.BATTEN_TRANSCRIPT_FILEdoes not help, because the capture store is not transcript-shaped. Filed separately if wanted.
Land this early and independently of any wave. Its value is that it stops the next session losing the same hour, so it is worth strictly more the sooner it lands, and it shares no file with the migration work.
Refinement — Ready

board-payloads' absent-transcript error, names a reachable payload source. Asserted as a test over the strings: every one of the four mentions eitherboard-payloadsorbatten capture, andboard-payloads' own absent-transcript path mentionsbatten capture. A remedy that names neither fails. - Effect (§3).

Acceptance
- All four messages name a payload source that exists on a transcript-less host.
- The three-command capture recipe appears once, canonically, rather than copied into four strings.
- A test refuses a remedy naming neither source, shown red before and green after.
- The larger
board-payloadschange is filed rather than implied, if it is wanted at all.
Built — plus a trap this fix walked into, and one handoff hazard it creates
Branch claude/gate-remedy-payload-source, off main and independent of CLOUD-911's wave, so it can land first: its whole value is stopping the next session losing the same hour.
All four messages carry the source now, with the canonical recipe in board-payloads' absent-transcript error because that is where every other gate sends the reader. tests/remedy-payload-source.bats, 6 cases, green; config-lint 0 smells. Shown able to fail (CLOUD-418) by stripping the clause from one message — cases 2 and 4 red, the other four stay green, so the predicate is specific rather than a blanket.
One framing decision, because it decides whether the remedy is used at all: the capture route is written as equally valid, not as a fallback. A hedged remedy reads as second-best and gets skipped by exactly the agent who most needs it, so a case asserts all three refusals say the bytes came from the tracker.
The trap: an apostrophe breaks the guard, and it breaks it as a HOOK
Writing "the tracker's own bytes" into issue-read-guard.sh broke the guard. Both denies are jq programs inside a single-quoted shell string, so one apostrophe terminates the program and the script stops parsing. The original text avoids apostrophes throughout, and nothing said why — it read as style.
What makes it worth a case rather than a note: issue-read-guard is a PreToolUse hook, so the breakage does not surface as a test failure. It surfaces as every mediated call erroring — measured here, the next save_issue failed with the hook dumping a bash syntax error, which is how it was caught at all. Loud, but late, and the obvious phrasing walks straight into it.
So case 6 pins it: bash -n over both scripts, plus an assertion that the deny string carries no apostrophe. That case is proven able to fail, because the apostrophe version really did red it minutes earlier. shellcheck in the hk gate catches the parse error too; the case names the cause, which the parse error does not.
The hazard: two of the four files are PR-G's to delete
mise-tasks/issue-read-guard.sh and mise-tasks/issue-search-guard.sh are inside the mediated-call retirement's domain — CLOUD-926's PR-G, draft #668, which plans nine mise-tasks/*.sh deletions as those guards move into the engine. #668's diff does not touch either file today, so there is nothing to resolve now.
The risk is not a conflict, it is a silent loss. If PR-G retires either guard, the clause added here disappears with the script, and the engine-minted deny that replaces it carries whatever text the port gives it. CLOUD-908's conserves ratchet governs the test cases a deleted suite must account for; nothing makes a port account for a refusal's remedy text — which is exactly CLOUD-871's gap, one level down.
Whoever lands PR-G carries these two clauses into the engine's deny text. tests/remedy-payload-source.bats is what fails if they do not: its setup slices both files by path, so deleting one reds the suite loudly rather than quietly dropping the guidance. That is deliberate — the suite is the handoff, not this paragraph.
One apparent counterexample, chased down rather than left standing
After the fix was written, a PostToolBatch advisory emitted completion.unlanded .claude/.transcript.jsonl:1518 — a pointer into the very path this row says does not exist, with a line number. If a transcript were really there, the central claim above would be wrong and the fix would be aimed at the wrong thing, so it was checked rather than waved off:
Glob .claude/.transcript.jsonl— no files found.batten state list— three findings, every one keyed torefs/heads/claude/gate-remedy-payload-source. None keyed to a transcript.board-payloadshad already refused on that exact path.
So the :1518 is the rule's declared subject — the configured [transcript] path from batten.toml:157 — not evidence that anything read 1518 lines from it. completion.unlanded decides nothing itself; it reads the engine's state store and points at the configured path, which is exactly what CLOUD-819 describes for Capability::Absent.
The claim stands, on two independent observations. This is recorded because the next reader will meet the same pointer and reasonably suspect the row is stale — a finding-shaped pointer at an absent file is confusing on its own terms, and that confusion belongs here rather than being rediscovered.
What would change the fix: if some host DOES materialise that symlink mid-session (stop-guard is what maintains it), then board-payloads starts working there and the capture route becomes the second source rather than the only one. Neither reading changes what this row does — every remedy should name both sources either way — which is why the fix was not held pending the answer.
The recipe this row installs has two footguns, and both bit the session that wrote it
The fix above makes four messages name batten capture show. Measured on the next session to follow that recipe — the same one, an hour later — the recipe is reachable but not safely usable, and both hazards produce a confident wrong answer rather than an error. That is this row's own subject one level in: a remedy that exists but misleads is the failure mode it was filed against.
1. --grep exits 0 whether or not it matches
The canonical recipe's middle step is "find the right one", which invites exactly one shape:
for h in $(batten capture list | ...); do
if batten capture show "$h" --grep '"id":"CLOUD-859"'; then echo "HIT $h"; fi
done
Every handle is a HIT. --grep prints matches and exits 0 regardless, so the loop above reported 8 false positives out of 8, and a no-match pattern (ZZZ_NO_SUCH_STRING_ZZZ) also exits 0 with empty output. The usable form decides on output, not status:
n=$(batten capture show "$h" --grep '"id":"CLOUD-859"' | wc -c)
[ "$n" -gt 0 ] && echo "HIT $h"
This is verdict-not-discarded's concern wearing the opposite mask. That gate refuses a command whose exit status is thrown away; here the status is faithfully read and means nothing, which no gate catches and which reads as correct. grep(1) itself exits 1 on no match, so the name imports an expectation the flag does not honour.
2. A bare digest is not a handle, and the failure is nearly silent
capture list prints <stream>:<digest>. Stripping the prefix — natural, since the digest is the identifying part — yields:
batten: capture: "3a7153b9…" is not a handle — write `<stream>:<digest>`, as `batten capture list` prints them
which is a good message. But it goes to stderr, and inside a for loop with 2>/dev/null (added to suppress the noise of scanning ~200 captures) every call fails and every grep comes back empty. Combined with hazard 1 the result is a scan that completes cleanly and finds nothing.
Measured consequence: the session concluded "the CLOUD-859 payload is not in the capture store", stated that to its human as a finding about the store, and began reasoning about whether MCP responses are captured at all. Both were wrong. The payload was there the whole time; the handle was malformed and the grep could not report it.
Why this belongs on this row rather than a new one
The fix above chose the capture route as equally valid, not a fallback — deliberately, and the reasoning holds. But the strength of that framing is what makes these hazards expensive: an agent told the route is first-class trusts it, and a scan built on --grep's exit status confirms whatever it already believed. Two of this row's own arguments now cut against its remedy:
- it argues a remedy must be followable, and a recipe whose "find the right one" step cannot be scripted correctly is followable only by someone who already knows the answer;
- it argues a paraphrase is the forged-compliance shape, so the capture route is the only honest source here — which means a false "not in the store" reading pushes the agent straight back toward either a bypass or a re-typed payload. Both are the outcomes this row exists to prevent, arrived at through the door it opened.
The narrow fix, and what is deliberately not in it
In scope for a follow-up, not for this branch (which is verified, pushed and reviewed — reopening it to add a --grep exit code would widen a text-only change into a CLI behaviour change):
--grepshould exit non-zero when nothing matched, asgrepdoes. That is a behaviour change to a published verb and belongs in its own row with its own §6, because a caller may already depend on the current status.- Alternatively or additionally, the canonical recipe should not need a loop at all.
capture listcould take the pattern, orcapture showaccept a bare digest when it is unambiguous. Either collapses the middle step and removes both footguns at once — and matches the fix's own step 3, already filed-not-implemented: "teach board-payloads to read the capture store directly, so the recipe collapses back to one command".
Not proposed: changing the handle format. <stream>:<digest> is load-bearing — capture.rs keys stdout, stderr and response separately so a predicate scoped to one stream cannot match another, and the error message already names the right form.
Recorded now rather than at implementation time because the cost is measured and specific: two sessions have now lost time to the payload route, the first because it did not exist and the second because its lookup step lies about matching. The second is the smaller bug and the easier one to leave un-filed.

Compare
`modifier_admits` was applied to `matching_receipt_rows`' tool-keyed loop alone, so a write- or command-triggered receipt row carrying `when_absent` or `when_present` still reached `required_checks_for`. The boundary then resolved — and paid git work for — a receipt obligation the row does not admit, and the gate judged a row the selection should have dropped. The function's own header claimed the opposite: that three readers share one implementation so the boundary and the gate cannot disagree about which rows fire. That was true of the tool loop and false of the other two, which is the worse failure of the pair — a comment asserting an invariant the code does not hold is what stops the next reader checking. The invariant is per-loop, so it is now written per-loop and the header says so. Also: the row-1 fixture minted its receipt against `HEAD` where `issue-search-check` records `origin/main` with a `-` fallback. The two agree in that fixture and diverge the moment it grows a local commit, at which point the body is one the real task cannot produce — so the suite would have stopped exercising the `stale-main` contract while still passing. It resolves the base the task's way now. Both found in review on #680, and both are the same class: a narrowing that holds on the path someone tested and not on its siblings. Carries `when_value` too, which row 3 needs and row 1 did not: that guard gates ONE transition, and `when_present` can only ask whether the call named a state at all. Its header prices the difference in the same terms row 1's does — gating every column "is how a guard gets switched off within a day". The comparison folds case and drops the three separators a tracker treats as noise, so a column's spellings are one move; which value matters stays in the consumer's config. Refs: CLOUD-987

…es it `when_value` is permitted on `shape` and `receipt`, and both its checks sat in `validate_receipt_columns` — which returns early for every other kind. So a `shape` row carrying the column with no `when_present` loaded clean and narrowed nothing: a column that reads from the file as a narrowing and performs none. Moved to `validate_polarity`, which every kind reaches. The emptiness test was also the wrong predicate. It read the raw string, so it caught `""` and let `"___"` and `"---"` through — and those fold to nothing and then compare equal to any value made only of separators.

It folds first now. `hook::comparable` is `pub(crate)` so the load-time check and the runtime comparison cannot disagree about what folding means — the same reason `modifier_admits` has one implementation. The regression case runs both kinds against all four inputs that fold to nothing. Under the previous code it reds twice per kind, which is what makes it a test rather than a restatement. Also carries `key_shape`, which row 2 needs: the tracker's `id` accepts a UUID as well as an issue key, and resolving one needs a credential no hook has. The retiring guard calls that a genuine cannot-look and ALLOWS — "denying would refuse a legitimate update over a spelling the agent is entitled to use". Without a shape constraint the engine would file the UUID as a subject, find no file and deny, which is strictly stricter than the bash on the one call the bash was careful about. A value the shape does not match resolves the subject to absent, which `verdicts` already takes to could-not-look. Found in review on #680.

`modifier_admits` was applied to `matching_receipt_rows`' tool-keyed loop alone, so a write- or command-triggered receipt row carrying `when_absent` or `when_present` still reached `required_checks_for`. The boundary then resolved — and paid git work for — a receipt obligation the row does not admit, and the gate judged a row the selection should have dropped.

That was true of the tool loop and false of the other two, which is the worse failure of the pair — a comment asserting an invariant the code does not hold is what stops the next reader checking. The invariant is per-loop, so it is now written per-loop and the header says so. Also: the row-1 fixture minted its receipt against `HEAD` where `issue-search-check` records `origin/main` with a `-` fallback.

CLOUD-909's harness drives `batten check -J` and compares house-style §6's `path:line` pointer set. Every row of CLOUD-312's retirement wave is a `PreToolUse` or `Stop` body, so all ten were structurally unable to produce the evidence the campaign requires of them: the task would run the dying suite, capture its fixtures, and then ask `batten check` about a mediated row it never evaluates — reporting a pointer-set difference on every faithful port. A harness that cannot be satisfied is the failure `mutant`'s header warns about, so it is fixed once here rather than worked around per row. Three things had to change, and none of the tree arm's comparison transfers. The shim now captures stdin and feeds it back. A hook body's entire input is the envelope on its stdin, so a capture without it recorded the directory the call ran in and nothing about the call, and the head side had no envelope to adjudicate. Fed back rather than merely consumed: a shim that swallowed stdin would change the behaviour of the suite it exists to observe. `replay-call:` is its own keyword rather than a flag on `replay:`, because the comparison axis differs in every column. A hook emits no pointer, so the analogue of the pointer set is the DECISION, read from each side the way that side expresses it — the shell body denies by printing a decision document and exiting 0, the engine denies with exit 2 (§7). The declared translation is therefore `deny=2 allow=0`, and the identity refusal does not apply to it: the left side is a decision rather than a code, so there is no inverted contract to carry over. An undeclared decision is still a refusal. A third check has no tree-arm counterpart and is the one worth having: a call denied by a NEIGHBOURING row reads as a faithful port of the row being retired. So a deny must name the row the `replay-call:` line declares. The rule id is a pointer, which is what rule 4 permits; the content is not printed. Refs: CLOUD-909
`issue-search-guard.sh` is deleted. 93 lines of bash whose whole decision is now `filing-needs-a-search` in `batten.toml`: a `receipt` row keyed on the tool the call names, narrowed by `when_absent = "input-id"` to the call that CREATES a tracker row. The modifier is why this could not be config until now. Only creates are gated, and the script's own header prices the alternative — gating updates "would demand a search before every edit to an issue, which is absurd and would get the guard switched off within a day." A table that could not tell a create from an update had to gate both or nothing. The suffix match the script hand-rolled is `selects_tool`'s now. It hand-rolled it because it could not trust its own wiring: CLOUD-178 measured one connector exposed under three prefixes across registration episodes, so a rule naming one matched none of the others, silently. TWO SUPPORTING CHANGES, both prerequisites rather than tidying. `when_absent`/`when_present` are permitted on the receipt kind, and `modifier_admits` is now one implementation read by three callers — `tool_rules`, `tool_receipt_rules` and `matching_receipt_rows`. The third is the one that matters: it is what the BOUNDARY selects with, so what resolves receipts and what then judges them cannot disagree about which rows fire. `key_base_for`'s header states the same obligation for `requires_key`. `issue-search-check` now records the `origin/main` it searched against. It wrote existence alone, and `receipt::branch_validity` refuses a body that cannot say what it was taken against (CLOUD-516) — so the row replacing the guard would have been not merely weak but SILENTLY UNPASSABLE, denying every filing with a receipt sitting in the store. The invariant is right and the shell receipt was the weaker of the two: a branch name outlives the branch it described, and `git checkout -B <name> origin/main` recycles one, so a name-keyed receipt lets a previous occupant's search authorise this occupant's filing. All four arms. MAPPED: ten cases, six carried, three subsumed, one changed (the bypass is gone — a mediated deny takes the engine's hatch, the consolidation CLOUD-442 and CLOUD-444 already made). REPLAYED: a `replay-call:` row against 8e0acf1. REMEDY PRESERVED: the refusal still names `issue-search-check` and says a zero-hit search still mints. DECLARED row, registration, script and suite deleted here. The mutation observed red is the modifier: admitting every call reds `an_update_is_never_gated` and nothing else — precisely the case the retiring header warns about. Refs: CLOUD-312

Three defects, one root cause, and the cause is the part worth recording: each time I added a narrowing to the path I was testing and then wrote a comment saying it held everywhere. Third consecutive review round finding the same shape. `key_shape` FAILED OPEN. `Regex::new(shape).ok()` discarded an unparseable expression per call, the subject resolved to absent, `verdicts` read that as could-not-look, and the call was ALLOWED — so a typo silently disabled the row it qualified. Compiled at load now, beside `resolves.reference`, whose comment already gives this exact argument. The column's own doc comment claimed the check existed before it did, and that half is worse than the missing check: a stated invariant is what stops the next reader looking. The comment now says what happened. `named_receipt_subject` scanned every receipt row for the first `key_from` rather than selecting from the admitted ones, so with two such rows an unadmitted row's projection could supply the subject for an admitted row's receipt. One row is declared today, so it was latent — which is what it was last round too, one function over. The polarity modifiers reached only `tool_rules`. They are permitted on any `shape` row, so `shape_rules`, `content_rules` and both ceiling evaluators ignored a column their rows could carry. `shape_rules` held the command string alone and structurally could not read a projection of the call's arguments, which is why it now takes the envelope — the signature was the tell. Each arm observed red on its own mutation, and ONE AT A TIME for a reason: nextest cancels the run at the first failure whatever `NEXTEST_FAIL_FAST` says, so a combined pass reported "1 failed" while 1,378 of 2,271 tests never executed. Read as a pair that looked like one discriminating arm and one dead one; the second arm discriminates fine when it is the only mutation in the tree. The command-keyed case is end-to-end through the binary rather than over `shape_rules` directly. A unit case aimed at one evaluator is exactly the shape that missed this three rounds running. Refs: CLOUD-987
`filing-needs-a-search`'s reason told the reader to run `mcp__Linear__list_issues` by name. That prefix is not stable: the same connector is exposed as a readable alias, as a bare UUID, and as the local-CLI form across registration episodes within one session, and this session hit the flip while acting on this very row's refusal. Every other mention of those prefixes in the tree is a COMMENT explaining that hazard. This was the one live instruction that named a single form, so it is wrong for whichever episode does not match — the same defect `.claude/rules/scanning.md` records for itself in CLOUD-998, where a row named `grep` and the gate below refused exactly that. Names the suffix to search for instead, which is what `board-payloads` already matches on and what the connector memory prescribes. Refs: CLOUD-178

…ot miss it `matching_shape_rows` held the command string alone, so it structurally could not read a projection of the call's arguments. `shape_rules` compensated by applying `modifier_admits` after the call; `Policy::key_base_for`, the other caller, did not — and it returns the `base` a keyed row is judged against, so a row excluded by its own modifier handed the commit range to a later, admitted row. Wrong key evidence, from a row that was not supposed to fire. THE FOURTH APPEARANCE OF ONE DEFECT. The narrowing was added to `tool_rules`, then `matching_receipt_rows`, then `shape_rules` — three call sites in turn, each round leaving the next one out, each time with a comment claiming it held everywhere. So the check moves INSIDE the selector rather than to a fourth call site: a future caller cannot forget what it never had to remember. `manifest_ceiling_for` and `reads_prospective` filter too, and the comments state what kind of defect that was. Neither could deny a call its modifier excludes — `ceiling_rules` and `content_rules` re-check before refusing — but an unadmitted row bought a git query or a file read for a verdict nothing would consult, against the cheap-when-irrelevant discipline both headers claim. Also `project_uses`: two crate roots resolved every declared path against whichever `lib.rs` came first, so a set spanning two crates resolved crate B's edges against crate A's `mod` list — the plausibly-wrong answer in the function whose own header disclaims it. Two roots now resolve nothing, which is the same honest failure the no-root case already had. Shown able to fail, one mutation at a time (CLOUD-418). Commenting out the selector's check reds both the new case and the earlier round's `a_command_keyed_row_honours_the_polarity_modifier`; restoring the `find` in `project_uses` reds `two_crate_roots_resolve_no_edge_at_all`, whose two roots export different names so the wrong table is observable rather than inferred. Run together they were inconclusive — nextest cancels on first failure, the trap this repository already recorded — so they were split. Refs: CLOUD-987

`default_trait_access` refused `Default::default()` at both arms of the single-root match. The type is `uses::RootExports`, so it says so. Behaviour is untouched — `two_crate_roots_resolve_no_edge_at_all` still holds, and its mutation still reds it. Caught by `verify`, not before it, and the reason is worth recording: the `lint:clippy` run that preceded this was backgrounded, and `rules.rs` was edited while it ran, so its exit 0 covered a tree that no longer existed. Third variant of one mistake this branch has now made — a torn `test:bats` run, a voided step receipt, and this. A check's verdict covers the bytes it read and nothing later. Refs: CLOUD-987

Bundle G part 2: CLOUD-312's retirement wave. Part 1 (#668, merged) built the four
instruments the wave needs — CLOUD-924, 925, 987, 988. This PR spends them.
Row 1 is retired.
mise-tasks/issue-search-guard.shand its suite aredeleted; the decision is
filing-needs-a-searchinbatten.toml— areceiptrow keyed on the tool the call names, narrowed by
when_absent = "input-id"tothe call that CREATES a tracker row.
That narrowing is why row 1 could not be config before. Only creates are gated,
and the retiring script's own header prices the alternative: gating updates
"would demand a search before every edit to an issue, which is absurd and would
get the guard switched off within a day." A table that could not tell a create
from an update had to gate both or neither.
Four arms, per the campaign's protocol
carried, threesubsumed, onechanged(the bypass is gone; a mediated deny takes the engine's own hatch,the consolidation CLOUD-442 and CLOUD-444 already made).
replay-call:row against the base rev.issue-search-check, still saysa zero-hit search mints, and now carries CLOUD-990's payload-source recipe.
.claude/settings.jsonregistration, theMUTANT_GATESentry and thebench/suites/RESULTS.mdrow.Four prerequisites this turned up, each fixed rather than filed
retirement. Its head side was hardcoded to
batten check -J, the shimdiscarded stdin, and a hook deny carries no
path:lineto compare. Every oneof CLOUD-312's ten rows is a
PreToolUse/Stopbody, so all ten would havefailed the REPLAYED arm for a reason that was the harness's rather than the
port's — a harness that cannot be satisfied, which is the failure
mutant'sheader warns about one level up.
replay-call:is the new arm: the capturedenvelope goes to
batten hook --harness exit-code, and the compared axis isthe DECISION plus the row that answered, because a decision matching for
the wrong reason is the false green the task exists to catch.
issue-search-check's receipt lacked thebaseline.receipt::branch_validityrefuses a body that cannot say what it was takenagainst (CLOUD-516), so the replacement row was not merely weak — it was
silently UNPASSABLE, denying every filing with a receipt sitting in the store.
The invariant is right and the shell receipt was the weaker of the two, so the
receipt was fixed.
when_absent/when_presenthad to be permitted on the receipt kind, andmodifier_admitsis now one implementation read by three callers —tool_rules,tool_receipt_rulesandmatching_receipt_rows. The third isthe load-bearing one: it is what the BOUNDARY selects with, so what resolves
receipts and what then judges them cannot disagree about which rows fire.
key_base_for's header states the same obligation forrequires_key.issue-search-guard.batsandcontract-drift.batsboth name a case "the bypass is honoured", and theledger keys arms on the quoted string — so a bare arm made two arms claim one
case.
<suite>::<case>disambiguates, andreplay.shtries the qualifiedform before the bare one; borrowing a
changedarm is the worst direction,since it excuses a case from being replayed at all.
What the gates caught that review would not have
Four defects in my own work, each computed rather than noticed:
no-consumer-repo-namefailed the build because a consumer's policy filenamehad reached
crates/**— non-negotiable rule 1, while porting a row whoseentire argument is that consumer facts belong in the consumer's config. The
modules are copied by enumeration now, which is also robust to a module being
added.
//!doc comments where the ledger reads//, so all eleven registered as nothing. Green, and asserting nomapping at all.
case-target-missing, or "a migration that did not happen".remedy-payload-source.bats(landed onmainmid-branch) caught that my portdropped a clause of the remedy it had just added. The suite now slices the
search refusal from
batten.tomlrather than from the deleted script.One unrelated latent defect fixed in passing:
pointer_only.rspanicked onwrite stdin: BrokenPipewhen a verb that reads no stdin exited first — a racewhose outcome says nothing about what the run emitted. Any other error still
panics.
Verification
mise run verifygreen, rebased on currentorigin/main. The CLOUD-418 mutationfor row 1 is the modifier: making
modifier_admitsadmit every call redsan_update_is_never_gatedand nothing else — precisely the case the retiringheader warns about.
Status of the rest of the wave
Rows 2, 3, 4+8, 5, 6, 7, 10 plus CLOUD-892 and CLOUD-917 are not in this PR
yet. Rows 1 and 3 are now expressible on CLOUD-987, row 2 on CLOUD-988; rows 4
and 8 remain coupled through
mcp-allow-check's--coversunion and must land inone commit.
CLOUD-312 stays open regardless: rows 11 (
run-shape-guard, behind CLOUD-613)and 12-13 (the two
$HOMEscripts, CLOUD-605) remain after the whole wave, so itsend-state test cannot hold and
doctor hookscannot reportsiblings == 0.This PR closes nothing, deliberately
DO-NOT-CLOSE
CLOUD-903's undrainable shape, stated rather than worked around. The work here is
row 1 of thirteen on CLOUD-312, and that row is not a tracker issue of its own
— so there is no key whose Done condition this satisfies. CLOUD-312 itself stays
open by construction: rows 11 and 12-13 remain after the entire wave, so its
end-state test can never hold on this branch.
The other keys in this body are cited as evidence — the issues whose measurements
and mechanisms this change rests on — not claimed. CLOUD-909 is served by the
replay-call:arm in the sense that its harness is extended, but extending alanded mechanism is not completing it, and it is already Done.
