/**
 * arguments/checks — the declared-sources checks: where the model SAID a value
 * came from, checked against the one place that source lives.
 *
 * Pattern: Walker, pure. `checkSource` is a function of one argument's value,
 *          its rule, the model's claim about it (`_findings.from`, read by
 *          `sources.ts` · `readSources`) and the corpora the layer is handed
 *          (`SourceCorpus`). The same inputs always give the same verdict; no
 *          clock, no model, no scope.
 * Role:    core/ layer, the inputs layer (honesty layer 2), step 5. Loaded with
 *          the layer's stage bodies (`resolve.ts` imports it; both through
 *          `import()`), never on a plain agent's graph. Imports nothing from
 *          `findings/` (the one-way law): the mount builds the corpus and hands
 *          it in.
 * Emits:   N/A.
 *
 * ## One claim, one corpus — and a pass is never support
 *
 * Every check is whole-token membership (`lib/normalize.ts` · `tokenize`
 * and `canonicalForm`, the evidence gate's own "same value", through
 * `evidence/resultCarries.ts` · `canonicalTokens`) in the ONE place the
 * claimed source lives:
 *
 * | Claim     | Checked against                                                       | Verified as                        |
 * |-----------|-----------------------------------------------------------------------|------------------------------------|
 * | `user`    | the quote in the person's own messages; the value in the quote, or a phrase the author declared for it | `said` (`matched: 'quote' \| 'phrase'`), or a READING |
 * | `result`  | the named result's own bytes (`evidence/resultCarries.ts` · `resultReader`, read once per batch) | `result` (`setAside` when the model set it aside) |
 * | `turn`    | the person's earlier answers to the library's ask (the ledger's `answered` rows) | `answered` (`matched: 'spelling'` across `24h` ↔ `-24h`) |
 * | `app`     | the app's own text (system messages, the composed system prompt, `externalGrounds`) | `app` (`appSource` = the ground's label) |
 * | `assumed`, nothing | nothing — the model's own                                    | `model`                            |
 *
 * A failed check is FILED as written (`failed`), never repaired and never
 * retried against another corpus: a false claim is itself a fact. For a failed
 * claim and for the model's own value, the library still looks the value up
 * (`coincides`) — a HINT for the lens and the bench, never a source, never
 * support, never enough to skip an ask.
 *
 * Membership can REFUTE a claim ("those words are not in any message you
 * sent"); a pass proves nothing — the words can be there by coincidence, in a
 * negation, in another sentence. So no verdict here ever supports "known": a
 * pass only keeps a reason from firing (`assessment/assess.ts` ·
 * `readArgumentVerdicts`).
 *
 * ## The declared default beats the app and a result (V1)
 *
 * A value equal to the argument's own `assume` value that the checks did not
 * verify as the PERSON's (their quoted words, or their answer) is filed
 * `default`, the claim kept as written — a model that copies a default from a
 * description chose nothing, and a default must never earn more standing
 * through `app` or `result` than the same default declared as `assume`.
