/**
 * search/statementText — the rule for declaration text that can reach a
 * statement the library writes (`statement-text-refused`).
 *
 * Pattern: one pure rule, asked by `declaration.ts` at `defineTool` (an
 *          ERROR: `search` is a new API, so no consumer breaks), over the ONE
 *          list of texts that reach a statement (`statementTextsOf`).
 * Role:    semantics/ layer, pure.
 * Emits:   N/A.
 *
 * A declaration is untrusted text from the tool author, and a statement of a
 * negative claim is built from it — the source, the subject, each fixed
 * qualifier and default as `name: value`, each argument's name, each gap's
 * `what` and `why`. Three layers hold it, and only the last is the boundary:
 *
 *   1. SHAPE — one line of at most {@link MAX_STATEMENT_TEXT} characters, in a
 *      stated character class: letters, combining marks, digits, spaces and
 *      `. , : ; ' ( ) - _ / & % + # @`. No format character (zero-width, a
 *      bidi override), no control, no quote mark, backtick or bracket a
 *      renderer could be broken out of.
 *   2. A HEURISTIC — the instruction phrases ("do not", "always", "tell the
 *      user", …), scanned after NFKC folding with format characters removed,
 *      so a fullwidth or zero-width-split phrase is caught. A denylist is
 *      never complete (confusables pass it); it catches the honest mistake.
 *   3. THE BOUNDARY — the statement renders declaration text as QUOTED DATA
 *      ATTRIBUTED TO THE TOOL, never as library-authored prose:
 *      `source (as the tool names it): "the incident store"`. Whatever the
 *      words say, the person reads them as the tool's, in quotes. The
 *      statement writer (the negative-claim checker's `statement.ts`) owns
 *      that rendering; this rule only bounds what it is handed.
