/**
* findings/reserved — the reserved `_findings` argument: its schema, the one
* decorator that adds it to a served tool, and the two peels that take it
* back off before anything else reads the model's words.
*
* Pattern: pure functions over plain JSON; no scope, no I/O.
* Role: core/ layer leaf. `withFindingsArgument` runs at the ONE decoration
* site (the committed tool list in `buildToolsSlot`, and the seed
* fallback) — and so does its sources-only twin, `withSourcesArgument`
* (declared sources without the ledger: ruled tools only, `from`
* alone); `splitFindings` is the FIRST read of a tool call's args
* in the dispatch loop; `peelAnswerFindings` runs before the output
* schema judges an answer, reading the answer's text through
* `answerText.ts` — the scanner the stream shares, so the answer
* returned and the tokens shown are the same text. `ledger.ts` turns
* what they return into rows.
*
* THE LAWS THIS FILE KEEPS
* - Never mutate a schema or an args object: every changed value is a
* rebuilt copy, and an unchanged one is the SAME reference (so an unarmed
* path, or a schema the author already decorated, is byte-identical).
* - `_findings` is never added to a tool's `required` and never touches
* `additionalProperties`; the author's own `_findings` property wins.
* - Never coerce, never infer: a field that fails its enum check is dropped
* and COUNTED (`malformed`), never defaulted. An absent declaration stays
* absent — `splitFindings` returns no `findings` for it.
* - `FINDINGS_ARGUMENT_SCHEMA` is the frozen base and is never edited. The
* OFFER (`withFindingsArgument`'s second argument — the ids of served
* results the model can still read: no standing, `fact` or `open`,
* newest first; `offer.ts · offeredResultIds`) is a rebuilt copy per call
* whose `previous.items.properties.toolCallId` carries `enum: offer`; an
* empty offer serves the base by reference. The offer is what the model
* may COPY, never what the library resolves: an id outside it is still
* recorded as the model wrote it (`ledger.ts · standingRowsFrom`,
* `unknownId: true`), never mapped to a position — and every id inside
* it resolves, because the rows are identified against the same served
* history the offer was read from (`offer.ts · knownResults`).
*
* Both model-facing strings here (`FINDINGS_INSTRUCTION` and the schema's
* description) say what the model may DO and never what the library
* guarantees; `test/modelFacingSurfaces.test.ts` runs them through
* `unprovable` so a later call cannot falsify a sentence.
