// src/utils/pendingVoiceFixes.js
//
// In-memory store for pending /voicediag remediation cards. Identical
// shape to pendingIgmpFixes / pendingHostAssigns — every entry is
// stamped with a `timestamp` on insert, and a background sweep expires
// un-acted cards after TTL_MS so the map never leaks.
//
// Entries hold:
//   {
//     storeNum,
//     personId,           // Webex person id the remediation targets
//     personLabel,        // displayName or email for message/audit
//     remediationId,      // e.g. 'disable_dnd', 'clear_forwarding_always'
//     remediationPayload, // free-form; whatever the check's remediation
//                         // handler expects (usually the pre-computed
//                         // PUT body plus contextual identifiers).
//     requester,          // from extractRequester(trigger)
//     timestamp,          // auto-set on .set()
//   }
//
// TTL matches pendingIgmpFixes at 15 minutes — long enough for a
// normal "let me check with the store first" handoff without leaving
// a stale card interactive past the point where the underlying state
// may have already been changed by hand.
