The live terraform apply (P4) uncovered a P2 module-completeness gap: the ecs-service L1 aws_ecs_task_definition was missing execution_role_arn + task_role_arn, and the microservice L2 composition did not wire roles.outputs.role_arn to the service. Fargate requires an execution role for ECR image pull. Fixed: interface.json + variables.tf + main.tf + composition.json wires. The iam-role assume-policy trusts ecs-tasks + the inline policy grants ECR pull + CW logs. A second live gap surfaced once the task definition applied: the ALB aws_lb had no security group (AWS rejects an ALB with an empty SG list). The platform VPC only outputs an ECS SG; the composition now wires platform_vpc.outputs.ecs_security_group_id to alb.inputs.security_group (the ECS SG opens port 80 to 0.0.0.0/0 — acceptable for an internet-facing ALB + dev pilot per D-020). No iam-role module changes were needed — its locals.tf already trusts ecs-tasks.amazonaws.com and grants ECR pull + CloudWatch logs by default. Live apply now succeeds: Apply complete! Resources: 0 added, 1 changed, 0 destroyed (task def + ECS service created on the first re-apply; ALB SG updated in-place on the second). Full suite: 844 passed. ---ci--- project: acdl phase: 4 milestone: v1.26 status: execute wave: W1 ---
