/**
 * Tracks every distinct ABDM consent ARTIFACT id discovered under a consent
 * request. Needed because a multi-facility M3 consent produces one artifact
 * per linked HIP facility, and the bridge's merged "fetch by consent_request_id"
 * call does not reliably keep returning sessions for artifacts that were
 * already individually resolved earlier (verified 2026-07-28: a previously
 * "received" artifact stopped appearing in the merged sessions list, while
 * still returning real data when queried directly by its own artifact id).
 * So HMS must remember every artifact id it has ever seen for a consent
 * request and keep polling each one individually, in addition to the merged
 * request-id call (which is what discovers brand-new sibling artifacts).
