/**
 * findings/contingent — no towers on unverified lemmas.
 *
 * Pattern: one pure rule over (the values a moment used, the corpus's
 *          carriers, the ledger's fold); the sibling of
 *          `integrity/unsupported-claim` (a value against the settled facts,
 *          at the answer) and `integrity/unsupported-argument` (a value
 *          against what was served, at dispatch). Those two ask "did this
 *          value come from a result at all?"; this asks "did it come ONLY
 *          from results the model itself set aside?".
 * Role:    core/ layer leaf. Two moments call it: `stages/route.ts ·
 *          judgeEvidence` over the values the extractor found in the answer
 *          (the gate's `EvidenceVerdict.grounded`), and `stages/toolCalls.ts`
 *          over the DATA values of a call's arguments (`groundedArgumentValues`
 *          below). Both hand the rows to `ledger.ts · recordFindings`, the one
 *          writer.
 * Emits:   N/A — the writer emits `agentfootprint.findings.contingent`.
 *
 * ## The owner's ask, and the rule that answers it
 *
 * Agents build theorem towers on unverified lemmas — a value read in step
 * two, judged noise in step three, and used in the answer anyway, where it
 * reads exactly like a fact — and the staircase comes down as circular. The
 * ledger already has the standings the model DECLARED (`fact` / `open` /
 * `noise` / `ruled-out`); the evidence module already knows which result
 * carried which value. The rule joins the two and infers nothing:
 *
 *   a value the model USES — in its final answer, or as an argument of a
 *   later call — that came from a result the model itself declared `open`,
 *   `noise` or `ruled-out` is recorded as CONTINGENT.
 *
 * The fences, because they are the rule's honesty:
 * - DECLARED STANDINGS ONLY. A carrier with no standing row is undeclared —
 *   not "unverified" — and the rule says nothing about it: an undeclared
 *   carrier means the value stands.
 * - THE LAST STANDING PER RESULT IS CURRENT. Read off `foldLedger(...)
 *   .standingOf`, the ledger's own fold — never a second fold here.
 * - EVERY CARRIER NON-FACT. A value several results carried is contingent
 *   only when every one of them holds `open`, `noise` or `ruled-out`; one
 *   `fact` carrier and the value stands. A value the corpus lists more
 *   carriers for than it keeps (`ValueCarriers.truncated`) is NOT judged —
 *   "every carrier" cannot be read off a prefix — and NOTHING is judged from
 *   a corpus whose token ceiling was hit (`EvidenceCorpus.truncated`): the
 *   results after the cut carried nothing into the index, so a `fact`
 *   carrier past it is invisible and a row read off the prefix would be
 *   false. The gate downgrades itself to record-only under the same flag;
 *   this check files nothing.
 * - THE SAME QUESTION THE GATE ASKED. A grounded value carries the exact
 *   spellings the gate looked it up under (`EvidenceVerdict.grounded[].forms`,
 *   `extract.ts · candidateForms`); the carriers are read under those and
 *   no wider set. One row per VALUE: two spellings of one value in one
 *   answer (`0xef0101`, `ef0101`) share a canonical form
 *   (`normalize.ts · canonicalForm`) and file once.
 * - THE EXTRACTOR DECIDES WHAT IS A VALUE. Both moments read
 *   `evidence/extract.ts`'s DATA rule (a digit and a distinctive shape, or a
 *   declared shape), so a word is never a tower and an all-letters name
 *   needs the shape the gate would need. Exempt values — the person's
 *   message, the app's prompt — are never contingent: the model had them
 *   from a source it never judged.
 * - ONE ROW PER VALUE PER MOMENT, never per carrier; the carriers ride the
 *   row, in wire order, each with the standing that made it one. At
 *   dispatch, every standing in the batch's `_findings.previous` is filed
 *   BEFORE the check, so a standing declared on a sibling call of the same
 *   batch governs this call's arguments too.
 * - THIS TURN ONLY. The carriers are the current turn's results
 *   (`EvidenceCorpus.carriers`); a result of an earlier turn of a continued
 *   conversation, whatever its standing, carries nothing here — a value
 *   taken from it is not judged and gets no mark.
 *
 * Both doors must be armed for any of this to run — `.findings()` (the
 * standings) and `.namesAndNumbersFromEvidence()` (the corpus) — and an
 * agent with one or neither records the bytes it always did.
