• 03:08 — Sent back to Founding Engineer (d20f6f1c) with detailed remediation steps. All 3 fixes are <10 lines each.
• 03:19 — Re-verified all 3 fixes in code: P0 ratelimit now exports object with .limit() method, P1 TRPCContextWithDb includes user/ip from JWT and x-forwarded-for, P2 screenshot capped at 500KB via Zod.
