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.
