/**
 * Group-level word verification — thin wrapper around the universal token API.
 *
 * Maps verifyToken results to group-specific statuses:
 * - 'verified' = exact counter match
 * - 'duress'   = duress token detected (with member pubkeys)
 * - 'stale'    = valid token from an adjacent counter (out of sync)
 * - 'failed'   = no match

/**
 * Verify a spoken word against the group's current state.
 *
 * Checks in order:
 * 1. Current verification word → verified
 * 2. ALL members' duress words within tolerance window → duress (with all matching members)
 * 3. Adjacent verification word within tolerance → stale (out of sync)
 * 4. None matched → failed
 *
 * Per CANARY-DURESS: the verifier MUST check all identities and collect all matches.
 * The verifier MUST NOT short-circuit after the first duress match.
 *
 * @param spokenWord - The word or phrase spoken/entered by the user (case-insensitive, trimmed).
 * @param seedHex - Group seed as a hex string.
 * @param memberPubkeys - Array of member pubkeys for per-member and duress checking.
 * @param counter - Current effective counter for the group.
 * @param wordCount - Number of words in the token (1, 2, or 3; default: 1).
 * @param tolerance - Counter tolerance window: accept tokens within ±tolerance (default: 1).
 * @returns `{ status: 'verified' | 'duress' | 'stale' | 'failed', members?: string[] }`.
 * @throws {RangeError} If tolerance exceeds MAX_TOLERANCE or memberPubkeys exceeds 100.
 *
 * @example
 * ```ts
 * const result = verifyWord('falcon', seedHex, [alicePubkey, bobPubkey], counter)
 * if (result.status === 'duress') alert(`Duress from: ${result.members}`)
 * ```
