/**
 * scripts/match — is a fenced block the program ONE call of this turn
 * submitted? Identity against the record, never evidence for a value.
 *
 * Pattern: pure function over the answer and this turn's rows.
 * Role:    core/ layer. Asked inside the ONE judge closure the Route decider
 *          builds (`stages/route.ts` · `judgeEvidence`, through `judge.ts`),
 *          before the names-and-numbers extractor reads the text — so the
 *          draft and the delivered candidate are read alike. Only under
 *          `.namesAndNumbersFromEvidence({ code: 'match' })`.
 * Emits:   N/A.
 *
 * ## The match rule: exact, after removing only the wrapper (design § 5.2)
 *
 * A block matches a call only when its content (`../evidence/codeRegions.ts`)
 * equals the program the call SUBMITTED to the tool, byte for byte. Nothing is
 * transformed: no trailing-space strip, no line-ending rewrite, no Unicode
 * normalization, no shape, no edit distance — each can change a literal and so
 * the program (`print(len("""A  \nB"""))` prints 5, its copy without the two
 * spaces 3; `"é"` written with a combining mark is one more character than its
 * NFC form). The strings are compared as they hold the text (UTF-16 code
 * units): for well-formed text that is UTF-8 byte equality, and for a lone
 * surrogate it is stricter, the safe direction.
 *
 * - Against the rows of the CURRENT TURN only; earlier turns are counted
 *   (`earlierTurnRows`), never compared, and a miss says "no submission of
 *   this turn", never "no submission".
 * - A block over `MAX_SCRIPT_BYTES` is `over-size`: no row keeps a program
 *   that long, so it is never compared.
 * - Two calls that submitted byte-identical programs: the block names the
 *   LATEST, counts the rest (`alsoMatches`) and carries its label.
 * - No nearest submission is ever named: a near match is a different program.
 *
 * WHAT A MATCH YIELDS. The block is script content: it is cut out of the text
 * the extractor reads, so it yields no value candidates — and it grounds
 * nothing: the evidence corpus is untouched, so a value in the prose that also
 * sits in the script still needs a result. A MISS stays in the text and is
 * checked as prose, exactly as today.
 *
 * COST. One linear scan of the answer (`codeRegionsOf`); each of at most
 * `MAX_CODE_REGIONS` blocks is looked up once among at most `MAX_SCRIPT_ROWS`
 * programs of at most `MAX_SCRIPT_BYTES` — within the 512 comparisons per
 * judged answer of design § 4.4. Earlier turns add nothing.
