/**
 * arguments/sources — where the MODEL says each argument value came from
 * (`_findings.from`), and the one reader of it.
 *
 * Pattern: Map. The vocabulary of a declared source and one pure reader that
 *          judges the model's `from` array against the call it rides on. The
 *          reader is called by the ONE reader of `_findings`
 *          (`findings/reserved.ts` · `readDeclaration`, under declared
 *          sources — `.inputsLayer({ argumentSources: true })` or
 *          `.findings({ argumentSources: true })`), so the inputs layer and
 *          ToolCalls' peel read one `_findings` the same way.
 * Role:    core/ layer leaf of the inputs layer (honesty layer 2). Imports
 *          nothing from `findings/` — the folder's one-way law. Small and
 *          synchronous on purpose: the one reader is on every armed agent's
 *          graph; the CHECKS (`checks.ts`) load with the layer.
 * Emits:   N/A.
 *
 * ## What the model may say
 *
 * ```json
 * "_findings": { "basis": "direct",
 *   "from": [ { "argument": "window",  "source": "user",   "quote": "over the last week" },
 *             { "argument": "host",    "source": "result", "id": "toolu_01AbC" },
 *             { "argument": "limit",   "source": "assumed" } ] }
 * ```
 *
 * `user` (+ `quote`, the person's words copied exactly), `result` (+ `id`, a
 * tool_result id), `turn` (the person answered it, when asked, earlier),
 * `app` (the app's own text carries it), `assumed` (the model chose it). A
 * declaration is a CLAIM: the library checks it (`checks.ts` · `checkSource`)
 * and files its verdict beside it; an unchecked claim is never trusted.
 *
 * ## Never repaired
 *
 * An entry is dropped and COUNTED (never defaulted) when it is not an object;
 * its `source` is outside the five; a `user` entry has no string `quote` or a
 * `result` entry no string `id`; its `argument` is not a top-level argument
 * this call carries a value for (a key the call left out, a missing value, or
 * a nested / non-primitive value — not ruled in this version); or an earlier
 * entry already named the same argument (the first wins).
