/**
 * Decides whether an issue is "done" based on the final verification verdict and
 * an acceptance-criteria comparison.
 *
 * An issue is "done" ONLY if the verdict is PASS AND every acceptance criterion
 * is matched-and-checked by the verifier. Otherwise it is "needs-human" with the
 * reason and the unmet/unmatched criteria listed.
 *
 * Two robustness properties (issue 06):
 *
 *  1. Matching is by NORMALIZED TEXT, not list position. The verifier's
 *     `CRITERIA:` checklist is free-form LLM output; it may reorder, reword
 *     slightly, or add extra lines. Each issue criterion is matched to a verifier
 *     entry by a normalized key (lowercased, collapsed whitespace, stripped
 *     trailing punctuation), so a reorder or cosmetic difference does not produce
 *     a false "needs-human". An issue criterion with no matching checked verifier
 *     entry is unmet.
 *
 *  2. "No criteria" is distinguished from "criteria failed to parse". A trivial
 *     ticket with NO acceptance-criteria section is a deliberate weak gate
 *     (warn-and-proceed → done on PASS). But a criteria SECTION that was present
 *     yet parsed to zero items is a malformed spec — you cannot verify what did
 *     not parse — so it is needs-human, never a silent done. The caller passes
 *     `sectionPresent` to make that distinction; omitted, it defaults to the
 *     trivial-ticket reading for back-compat.
 *
 * Pure (no I/O) so it is unit-tested directly.
