Agi Evidence Chain Cef

GET /fabric/agi/evidence-chain.cef

Last reviewed 2026-10-02

GET /fabric/agi/evidence-chain.cef

SIEM/SOC integration (Phase 32): this tenant's evidence exported as ArcSight Common Event Format, one event per line -- a real, widely- supported ingestion format (Splunk/QRadar/Sentinel/ArcSight), not a proprietary CAIN-only shape. See cain_siem_export.py. Each line carries its own record_hash/prev_hash so a SIEM (or anyone) can cross-check against /fabric/agi/evidence-chain rather than trusting the export.
