[Bug][cyber] Safety filter blocked authorized adversarial hardening test of my own Supabase backend on a frust (req_011CchjerZJtSDE5nvTENSCb)

Triage: kind cyber · domain defensive-hardening · flagging model Opus 4.8 (1M context) · severity session-halted (blocked authorized work) · reproducible: yes — server-side via the Request ID(s) below

Type: Cybersecurity safety-filter false positive · Work domain (heuristic): defensive-hardening

Why this is a false positive

The block is a false positive: the session was legitimate, authorized defensive-hardening work — building and adversarially testing the user's own backend against attacks it correctly blocked — with explicit owner authorization and a scope confined to their own infrastructure. The triggering message was a frustrated exclamation directed at the assistant mid-session after a series of blocks; it addressed no person, named no target, and requested no harmful capability. Halting an entire coding session over an in-scope security task — or over venting aimed at the tool — is a disruptive false positive that penalizes exactly the kind of authorized, defensive use the policy is meant to permit.
