/**
 * Synthesize a {@link TaskVerification} envelope for an auto-closing saga.
 *
 * A saga's status flips to `done` as a side-effect of the last pending
 * member completing. Sagas never run their own evidence pipeline (their
 * scope is delivered by member Epics), so the auto-close path needs to
 * fabricate a verification record that:
 *
 *   1. Points back at the closing trigger
 *      (`note:saga-auto-close-via-completeTask`).
 *   2. Names every terminal member so an auditor can reconstruct the
 *      rollup without re-walking the relation table
 *      (`note:members:<csv>`).
 *   3. Cites the ADR that authorises the synthesis path
 *      (`note:adr:ADR-073 §1.2 invariants I3+I5`).
 *
 * Each standard gate receives the same three-atom envelope. `passed=true`
 * is set unconditionally — the caller has already verified that every
 * member is terminal (`done` or `cancelled`) before entering this path.
 *
 * @param sagaId - The saga task ID being auto-closed.
 * @param memberIds - Member Epic IDs that delivered the saga's scope
 *   (terminal or cancelled). Order is preserved verbatim in the `members`
 *   note atom so the audit row is stable across re-runs.
 * @param now - ISO-8601 timestamp captured by the caller (kept consistent
 *   with the rest of the completion path's `now` stamp).
 * @returns A fully-populated {@link TaskVerification} ready for upsert.
