/**
 * findings/serve — the answer turn served from the ledger.
 *
 * Pattern: two pure functions over the folded ledger (the twin of
 *          `evidence/recovery.ts · evidenceRecoveryPiece`): no scope, no
 *          I/O, no clock. Same input, same bytes.
 * Role:    core/ layer leaf. `findingsLedgerPiece` composes the request-only
 *          system piece the wire joins AFTER the recovery piece (order
 *          recovery → findings, fixed) and the served-view rebuild recomposes
 *          with the same call in the same order, so the receipt agrees by
 *          construction. `collapseJudged` rewrites — on the WIRE only — the
 *          `content` of `role: 'tool'` messages the model has already judged
 *          to a ticket. Neither touches `history`; the window stage stays its
 *          only writer.
 * Emits:   N/A.
 *
 * ## The piece
 *
 * Headed by the context contract's own field meanings
 * (`lib/context-contract · CONTEXT_FIELD_MEANINGS` — one owner of the
 * vocabulary, quoted, never restated), then one bucket per field, each
 * marked "declared by the model": the model's words are quoted as its
 * declaration and nothing is inferred. A result the model never named is
 * counted as `undeclared` — the honest absence, never 'open'. After the four
 * buckets, `contingent (read off the record):` (9.110.0) lists the towers
 * on the record — one line per `ContingentRow`, the value the model used
 * and every result that carried it with the standing the model gave that
 * result (`contingent.ts` is the rule; this only quotes the rows; the
 * heading says the lines are the library's join, not a declaration). After
 * it, `unsettled by absence (read off the record):` (9.113.0) quotes the
 * rows the fold keeps beside a ruled-out standing whose only witness was an
 * absence — what the envelope, as the model was served it, said it did not
 * check and its `try_instead`, in its own field names (`unsettled.ts` is
 * the rule, and quotes nothing the model was not served; the model's own
 * ruled-out line stays in `limitations`, exactly as declared). Every
 * bucket is bounded
 * (`FINDINGS_PIECE_LIMITS`) and every overflow is STATED; an empty bucket is
 * omitted rather than rendered as "no facts". A basis-only ledger
 * (`foldLedger(rows).hasStanding` false) serves nothing at all.
 *
 * `undeclared` needs the set of tool results on the wire, which a pure
 * function cannot see — so the caller hands it `servedToolCallIds(messages)`
 * (the `role: 'tool'` ids in wire order) as the second argument. Both the
 * wire and the rebuild derive it from the same message list; a caller that
 * passes nothing gets a piece with no `undeclared` line, which is the same
 * omission rule the other buckets follow. The set itself — served ids minus
 * ids with a current standing — has ONE owner, `offer.ts · undeclaredIds`.
 * The schema's OFFER (`offer.ts · offeredResultIds`, newest first) is that
 * set PLUS the ids the model can still read and revise — a current `fact` or
 * `open` — read off the same served ids by the same owner, so the piece and
 * the schema cannot disagree about what is undeclared, and the undeclared
 * line is always a subset of what the schema lists.
 *
 * ## The proposition
 *
 * A basis row may carry the `proposition` the model declared BEFORE the call
 * (`_findings.proposition`, one line: what the call tests). An `open` or
 * `ruled-out` line quotes it after the model's own words — `… — tested:
 * <proposition>` — so what was ruled out, or left open, reads against what
 * the model set out to test rather than against hindsight. It is the model's
 * text, quoted as declared, under a bucket already headed "declared by the
 * model"; the piece never composes one. A fact line does not repeat it (a
 * fact stands on its assertions), and `predicts` is record-only.
 *
 * ## The cache
 *
 * The piece joins the ONE system block a cache marker covers:
 * `cache/CacheDecisionSubflow.ts · computeCacheMarkers` folds the base
 * system prompt's policy (`'always'` by default) in at index 0 of the system
 * slot, and `adapters/llm/anthropicCacheWire.ts · applyCacheMarkers` marks
 * the whole joined prompt as one block — and on that wire a changed system
 * block misses the message breakpoints after it too. So the piece carries no
 * byte that is not a function of its two arguments — no call number, no
 * clock (the first cut anchored the header to the iteration, and that one
 * token made an unchanged ledger a cache miss on every call) — and a call
 * that serves the same ledger over the same tool ids (a re-ask:
 * `output-retry`, `step-nudge`, `evidence-recheck`) reuses the cached prefix.
 * The third argument, the answer-turn ask (9.103.0, `answerAsk`), is a
 * build-time constant of the run — `'none'` by default, and under
 * `'quote-facts'` the constant `reserved.ts · FINDINGS_ANSWER_ASK` appended
 * as the piece's last section — so it moves no byte between two calls of
 * one run either.
 * A call after the ledger or the wire moved does not: a model that declares
 * on every call writes a new system cache entry on every call. That is the
 * cost the design page records beside the byte saving; the receipt hashes
 * the piece per epoch either way.
 *
 * ## The collapse
 *
 * The `placedToolResult` precedent: a tool message carries a ticket, not a
 * sentence — `{ collapsed: true, standing, toolCallId, ref? }` as JSON, no
 * model words. Only `noise` and `ruled-out` results collapse by default;
 * `'ledger-only'` collapses `fact` results too (bench-gated, never a
 * default). `open` and undeclared results stay verbatim. `toolName` and
 * `toolCallId` are untouched so the tool_use/tool_result pair stays
 * wire-valid and `window/toolNames · toolNameOfMessage` still finds the
 * name; count and positions are unchanged; an uncollapsed entry keeps its
 * object identity (cache markers address `messages[i]`); and when nothing
 * collapses the SAME array instance comes back — which also makes the
 * function idempotent, since a message already carrying its ticket is not
 * a change.
