## Summary Under iMessage `groupPolicy=allowlist`, group authorization could be satisfied by sender identities coming from the DM pairing store, broadening DM trust into group contexts.

## Details Affected component: `src/imessage/monitor/monitor-provider.ts`.

Vulnerable logic derived `effectiveGroupAllowFrom` using both the static group allowlist and DM pairing-store identities (`storeAllowFrom`). This allowed a sender approved via DM pairing to satisfy group authorization in groups even if the sender/chat was not explicitly present in `groupAllowFrom`.

This weakens boundary separation between DM pairing and group allowlist authorization.
