feat(facts)!: count a tool result's matching elements, and the conditions beside them - #717
Conversation
…ions beside them The read-the-review gate was unsatisfiable wherever its declared command's transport is refused. This container's proxy answers `gh api graphql` 403, so no record could ever be minted, `ready-needs-an-answered-review` read `Missing` on every call, and the deny printed a command that could not clear it. What that produced is the whole reason the column exists: `mise run land` readied and merged #708 with NO record in existence at all. A `[[fact]]` row may now name a `tool` instead of a `command`, and count the elements of a collection in that tool's RESULT which satisfy a predicate. `counts` names the collection, `where` narrows it to blocking elements, `blocking` adds a condition sitting BESIDE the collection, and `counts = "."` names a bare top-level array — the empty string stays a load error and `[]` iterates into N values, so neither could have named the payload itself. WHY `blocking` IS A COLUMN AND NOT A SECOND FACT. A page cap is a scalar next to the array, so `counts`/`where` structurally cannot reach it; a second `[[fact]]` cannot either, because a `counts` path resolving to a bool is could-not-look and such a row would deny forever instead of passing on a complete page; and no Rego module can, because `input.call` carries a tool's NAME and never its arguments. Losing it was a false green in the one direction this gate exists to prevent — an unresolved thread beyond the page reads as zero — so the primitive grew rather than the gate shrinking. TWO ROWS MAY SHARE A SELECTOR, and could not before. `record_agent_fact` took the FIRST matching row, which was correct while a selector was a command — two rows cannot declare one byte-identical command without being the same row — and wrong for a tool, whose methods answer different questions. Measured: with both review rows naming `pull_request_read`, the second never recorded, its check denied forever, and reading the reviews did not satisfy it. Every matching row is offered the result now and `counted` discriminates, because a row whose `counts` path is absent from this payload records nothing. `returns` is no longer ranked where `counts` decides. The order it encodes is a statement about `rows_declared` — `json-array` refuses a non-array, `json` counts it as one — and `counted` walks a path instead, answering could-not-look for a non-array AT that path whatever the column says, with `opaque` refused beside `counts` at load. Reporting a loosening between the two reachable values described a relaxation that does not exist. The consumer is this repository's own review gate, re-sourced to the tool that can answer it, with `review-happened` and `V-REVIEW-ABSENT` carrying the third condition the replaced `--jq` projection folded in. What that still does not catch is a PR reviewed only by its own author: a field-to-field comparison, CLOUD-859's, and deliberate forgery rather than the honest error this threat model names. `V-REVIEW-UNANSWERED`'s class narrowed with the fact. It read "an unresolved review thread, or no review from anyone but the author", which was true of the projection and would now send a reader looking for threads on a head whose only problem is that nobody looked. The end-to-end tier is `crates/batten/tests/review_answered.rs`, which main created when CLOUD-1059 retired the bats suite: its fixture now reads five columns across two rows rather than one command, records through an MCP tool name, and every count assertion reads the decoded subject rather than prose. BREAKING CHANGE: `facts::Declared` gains `tool`, `counts`, `where` and `blocking`, so a struct literal built outside this crate no longer compiles (`constructible_struct_adds_field`), and `trust::WeakeningKind` gains `FactCountingChanged` beside its two sibling fact kinds rather than at the end, which shifts the discriminants after it (`enum_no_repr_variant_discriminant_changed`). Appending the variant would clear one lint and leave the other, so it would buy no compatibility — only a table where the three fact kinds no longer sit together. CLOUD-690 §6 claimed patch-compatibility and deferred the library half to the semver gate per CLOUD-842; it answered, so the claim is corrected rather than the gate argued with. Below 0.1.0 release-plz bumps the patch whatever the type says, so this changes the record and not the version. Refs: CLOUD-690, CLOUD-859
Widening `ready-needs-an-answered-review`'s `checks` to name the second fact is a `rule-predicate-changed` weakening — a byte comparison with no ranking, exactly like `fact-command-changed` — so it would need grooming and an admission. A NEW `receipt` row is deny-only by construction: it adds refusals and can never remove one, so no `WeakeningKind` covers it. Measured: the base-ref class drops from three smells to two. Not a dodge of the gate but a smaller change to the thing it guards. The two records answer different questions from different methods of one tool, and a refusal naming one check should name the read that satisfies THAT check — the shared remedy had to describe both reads and could not tell a reader which was missing. Splitting them makes each remedy exact and leaves the existing row's predicate untouched. Refs: CLOUD-690, CLOUD-859
…an edit `config-lint`'s base-ref class reported two smells against `origin/main`: `fact-command-changed` at `fact[review-answered].answered-by` and `fact-counting-changed` at `.counts`. Neither says a bar was lowered. `trust.rs` documents both as deliberate over-reports — a command comparison is byte-for-byte because "there is no ranking of two commands", and a counting change is reported "in either direction, because the direction is not rankable", where "over-reporting is the safe direction, and the cost of a false report is one edit." So the refusal was not a verdict to override. It was the gate saying a committed declaration changed and it cannot rank the change — and the way to answer that is to stop changing the declaration. `WeakeningKind` carries `FactRemoved` and `RuleRemoved` and has no `FactAdded` and no `RuleAdded`, because a fact or a receipt row can only ever be the object of a refusal: declaring one more cannot lower a bar. `MintAdded` is the lone addition-shaped kind and exists for the opposite reason — a mint SATISFIES a gate, so its presence does lower one. Measured on this branch before the general case was drawn: splitting a second check out of an existing row's `checks` list into its own rule dropped the smell count from three to two with no new finding. So `review-answered` and `ready-needs-an-answered-review` are restored to `origin/main`'s exact bytes, and the tool-sourced predicate lives in rows added beside them: `review-threads-clear` with its receipt row, and `review-happened` with its own. `gh pr ready` now answers to THREE checks where main had one, and `CONFIG_LINT_BASE=origin/main mise run config-lint` reports 0 smells. THE RESIDUE, STATED RATHER THAN ABSORBED. The restored row still declares a command this container's proxy answers 403, so a hand-typed `gh pr ready` is still refused with a remedy nobody here can perform. That is the state on `main` today — this does not create it and does not widen it — and retiring that row trips `FactRemoved` and `RuleRemoved`, both real weakening kinds, so it wants a groomed decision of its own rather than a clause bolted onto this branch. CLOUD-859 owns it, and `FactRemoved`'s own doc already records the honest reading: a receipt row naming a fact nobody declares can never be satisfied, so the removal TIGHTENS. Refs: CLOUD-690, CLOUD-859
CLOUD-690 A `[[fact]]` cannot count the elements of a tool result that match a predicate, so the read-the-review gate is unsatisfiable wherever its declared command's transport is refused
Why Fourth in the capability-gap family. CLOUD-440 (commit objects), CLOUD-452 (document nodes) and CLOUD-496 (remote APIs) each record a class of policy that cannot live in The gap 452 does not cover. CLOUD-452's consumer is The constraint, measured (README, 2026-08-12, 4-core x86_64, release build, 100 timed runs, p95 of sorted):
~91 ms of headroom, and it is an absolute ceiling. The finding: the obvious consumer does not need a parse. The motivating case is a guardrail on context explosion — refuse a read that would blow N tokens into the caller's window. Walking it through:
So the parse cost, if any, lands on the retrieval verb rather than inside the mediated call. That collapses most of the design: the hook keeps a cheap monotone count, and the expensive half runs only when the caller asks for it. What would actually need this capability, and it is an open question rather than a claim: a rule whose verdict depends on structure rather than size — "deny unless the request names a specific symbol", "deny a file with more than N definitions". Nothing in the tree wants one today. Under CLOUD-452's own standard — "One consumer is a bash task that works; two is a capability" — the count is zero, so this issue records the gap and does not propose building it. Re-open predicate. A rule is proposed whose decision on the mediated path cannot be made from a count, a literal, or the call envelope, and needs the structure of a file the call names. That rule is the first consumer; a second makes it a capability. Constraints any eventual design inherits, recorded now so they are not re-derived:
Related, from when this was a record rather than a proposal — superseded as a §8 clause by the Refinement block below, which is now this row's one Blockers statement. The gap is narrower than this row's title, and that is what makes it buildable (2026-08-26)The comment above names the first consumer. Refining here, because the title's framing — structure on the mediated path — is now measurably too wide: structure already reaches the engine on that path, twice.
So the missing capability is not addressing structure. It is a predicate over a collection — how many elements of this array satisfy P — which neither channel can express: Naming it that way shrinks the design from a query language to one column pair, which is what keeps it inside house-style §8's narrowness. Refinement — Ready Refinement gate: Definition of Ready & Done. This body carries only specializations.
Acceptance
What this row does NOT settle, and CLOUD-859 ownsThe review predicate has a second half — at least one review whose author is not the PR's author — which is a field-to-field comparison and is deliberately outside §2 above. Equality-to-literal cannot express it, and widening the primitive to reach it is the first step of the query language this refinement exists to avoid. How CLOUD-859 composes that half (a second fact, a different tool projection, or a narrowing of its own Acceptance) is that row's decision, and pretending otherwise here would be specifying somebody else's predicate to make this one look complete. One consumer, not twoCLOUD-452's standard — "One consumer is a bash task that works; two is a capability" — is not met: this is one. The candidate second named in the comment above ( |

Included review availability: Your plan provides up to 10 included reviews per hour; 8 remain after this review.
A tool serves several methods and the method is an argument, so `tool` alone cannot tell one method's result from another's. The two review rows leaned on SHAPE to do it — `get_reviews` answers with a bare array, `get_review_comments` with an object — and shape is a proxy. Measured on this branch: one `pull_request_read` call with method `get_files` minted `review-happened` with `rows 3`, because a file listing is also a bare top-level array. That cleared the check asking whether a review exists, which is a false green in the one direction the gate is for. `when` is the column that says it. Same vocabulary as `where` and `blocking` — the same `Literal`, the same path grammar, equality only — read over `Envelope::input`, which is where the engine can see arguments and a Rego module cannot. It only ever narrows: fewer calls mint a record, so a check naming the row denies at least as often. Refused beside `command` at load, where the whole command line is already byte-compared. Two load refusals come with it, both mutually-unsatisfiable pairs rather than strict ones: * a NAMED `counts` path beside `returns = "json-array"` — the shape requires the payload to BE the array and a named segment requires an object, so the pair reaches could-not-look on every payload and a check naming it denies forever. `.` is exempt: it is the one path a bare array can carry. * `when` beside `command`. `fact_weakenings`' suppression of `FactReturnsLoosened` under `counts` now rests on those two refusals rather than on a claim that `counted` ignores `returns` — it does not, and the comment that said so was wrong. A named path can only carry `json`, which is one value; under `.` the two remaining values reach the identical verdict on every payload. A case pins that rather than the paragraph. Also here: the command row's comment block is restored to describing the command row, with the retained 403 residue stated beside it; the fixture reads each row's own `tool`, `when` and `returns` from the committed config rather than carrying its own; the fixture's receipt rows are split per check, so an assertion naming one read can no longer pass on the other's refusal; and a dead duplicate lookup in `fact_weakenings` is removed. Verified: test:cargo 2652, test:bats, policy-test, batten-check, schema-check, clippy, and `config-lint` 0 smells against origin/main — `when` is an added column on rows that are themselves additions, and `WeakeningKind` has no `FactAdded`.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
One counts path, two readings of whitespace. validate_one decides on path.trim() and counted evaluates on the raw path, so counts = " . " clears the json-array refusal and then resolves as a named segment, which answers could-not-look on every payload.

Why
The read-the-review gate was unsatisfiable wherever its declared command's transport is refused. This container's egress proxy answers
gh api graphql403, so no record could ever be minted,ready-needs-an-answered-reviewreadMissingon every call, and the deny printed a command that could not clear it.What that produced is the whole reason the primitive exists:
mise run landreadied and merged #708 with nofact.review-answered.*record in existence at all.What a
[[fact]]row can say nowA row may name a
toolinstead of acommand, and count the elements of a collection in that tool's RESULT which satisfy a predicate.toolrules::selects_tool_name—[[mint]]'s matcher, not a second onecountswhereblockingcounts = "."blockingis a column rather than a second fact because a page cap is a scalar beside the array:counts/wherestructurally cannot reach it, a second[[fact]]cannot either (acountspath resolving to a bool is could-not-look, so such a row would deny forever instead of passing on a complete page), and no Rego module can, becauseinput.callcarries a tool's NAME and never its arguments. Without it an unresolved thread beyond the page reads as zero — a false green in the one direction this gate exists to prevent.counts = "."exists because neither alternative could name the payload itself: the empty string stays a load error, and[]iterates into N values wherecountedrequires exactly one array.Two defects this found
record_agent_facttook the FIRST matching row. Correct while a selector was a command — two rows cannot declare one byte-identical command without being the same row — and wrong for a tool, whose methods answer different questions. Measured: with two rows namingpull_request_read, the second never recorded, its check denied forever, and reading the reviews did not satisfy it. Every matching row is offered the result now, andcounteddiscriminates because a row whosecountspath is absent from this payload records nothing.returnswas ranked wherecountsdecides. The order it encodes is a statement aboutrows_declared—json-arrayrefuses a non-array,jsoncounts it as one — andcountedwalks a path instead, answering could-not-look for a non-array AT that path whatever the column says, withopaquerefused besidecountsat load. Reporting a loosening between the two reachable values described a relaxation that does not exist.The consumer, and why it is ADDED rows
review-answeredandready-needs-an-answered-revieware byte-identical tomain. The tool-sourced predicate lives in rows added beside them —review-threads-clearwith its receipt row, andreview-happenedwith its own — sogh pr readyanswers to three checks wheremainhad one.That shape is
trust.rs's doing rather than a preference. Changing what answers an existing fact isfact-command-changedand changing how it counts isfact-counting-changed, both byte comparisons that report in either direction because neither is rankable.WeakeningKindhasFactRemovedandRuleRemovedand noFactAddedand noRuleAdded, because a fact or a receipt row can only ever be the object of a refusal.MintAddedis the lone addition-shaped kind and exists for the opposite reason — a mint SATISFIES a gate.So
CONFIG_LINT_BASE=origin/main mise run config-lintreports 0 smells, and nothing needed a groomed admission.What is deliberately not here
gh pr readyis still refused with a remedy unperformable here. That ismain's current state and this does not widen it; removing the row tripsFactRemovedandRuleRemoved, so it wants a groomed decision. CLOUD-859 owns it.landconsult — written, and blocked onmise-tasks/land.shretiring, sinceshell-retirementarm B refuses any in-place edit tomise-tasks/**andV-SHELL-RULE-EDITEDdeclares no override route. The 51-line diff and its reasoning are on CLOUD-859.config-linthole this branch found — a claim that groomed nothing reads as the absence of a claim, so a commit trailer admits a weakening alone. The one-conjunct fix and its discriminating case cannot land in place for the sameshell-retirementreason; filed as CLOUD-1078 with the patch and the evidence.--jqprojection folded it in; it is a field-to-field comparison that equality-to-a-literal cannot express.review-happenedcovers "no review at all" instead. An author reviewing their own PR is deliberate forgery rather than the honest error this threat model names, and CLOUD-859 owns the comparison.Also here
