Custom domain returns 404 "Application not found" with `x-railway-fallback: true` despite every control-plane signal healthy. Your AI support concluded this needs ops to inspect Fastly edge.

State (verified):

- Custom domain id: 48a0a708-16d6-4e6f-bb3a-8302ed6c7b2c (app.bizbrain.pro)

- Service: bizbrain-v2 (032e34db-ed8f-42b6-9622-6316d503d011)

- Project: 7983f168-e07d-44da-9075-8e61d267d152

- syncStatus: ACTIVE, targetPort: 8080 (matches Railway-injected PORT)

- DNS: app.bizbrain.pro -> ghbp4gtv.up.railway.app, propagated + currentValue == requiredValue

- TLS cert: valid Let's Encrypt, SAN includes app.bizbrain.pro

- Latest deployment: 72a4c699-2d2a-4005-a876-83bed9596ecc -> CONFIGURE_NETWORK completed with targetPort: 8080

- bizbrain-v2-production.up.railway.app/api/health -> HTTP 200

- app.bizbrain.pro/api/health -> HTTP 404 + x-railway-fallback: true

Already tried (with AI support help):

- customDomainUpdate: targetPort null -> 3000 -> 8080

- Delete + recreate domain (was orphaned from service networking; AI support re-attached)

- Multiple redeploys + deploymentRestart

- DNS re-pointed to new CNAME target after recreate

AI support's conclusion: "Fastly edge cache not invalidating or control-plane -> edge propagation failure. Requires Railway ops access."

Please verify Fastly routing entry for app.bizbrain.pro -> bizbrain-v2:8080 and force re-sync/cache invalidation.
