Leak-site claim

Attacker assertion only. Establishes: claim date, group, alleged victim.

Press / market report

State AG / regulator filingThis record

Unlocks: discovery date, data types, affected count, compliance clock.

SEC 8-K / victim statement

Unlocks: materiality, stated response, full audit trail. Ceiling removed.
