Scenario solution patterns

Encrypted cross-account artifact fails

Check the target role trust, assumed-role permissions, bucket policy, object ownership, KMS key policy or grant, organization controls, Region, and exact key ARN. Do not begin with administrator access.

ECS image deployment fails

Check image digest and repository, task execution role, repository policy, network path to ECR, task events, container health, target-group port/path, and deployment alarms.

Lambda canary fails

Confirm callers use the alias, inspect version-specific errors and latency, verify alarm dimensions, examine pre/post-traffic hooks, return the alias to the known-good version, and investigate duplicate asynchronous processing.

Compliance release is slow

Automate deterministic checks, produce an evidence bundle tied to the digest, and retain one accountable approval with timeout and audit.
