Phase 13 — l1-catalog-for-ecs (v1.2) VERIFY

Verdict: Phase 13: VERIFIED Tag: v1.2.3 Date: 2026-07-21

---

Scope

Phase 13 authors six IR-typed L1 modules for an ECS Fargate microservice (l1-vpc, l1-ecs-cluster, l1-ecs-service, l1-iam-role, l1-alb, l1-ecr), registers them in modules-ir/registry.json, and generalizes the Terraform adapter from S3-specific to a table-driven emitter handling all 12 IR types via TYPE_MAP + INPUT_MAP + OUTPUT_MAP. Requirement covered: REQ-31.

Verification layers

1. Structural

• 6 new L1 directories under modules-ir/l1/, each with interface.json + README.md.
• modules-ir/registry.json updated: 8 entries (7 L1s + l2-static-asset), all 6 new at 1.0.0, deprecated=false.
• adapters/terraform/adapter.py generalized: TYPE_MAP has 12 IR types; INPUT_MAP + OUTPUT_MAP for non-identity mappings; generic _emit_resource; S3 versioning NFR preserved.
• scripts/verify_phase13.sh exists (+x).
• .ciagent/PLAN.md updated to Phase 13.
• PASS.

2. Behavioral (scripts/verify_phase13.sh)

=== Phase 13 verification ===
L1 directories: OK (6 new + l1-s3)
  l1-vpc: aws:ec2:vpc (4 inputs, 3 outputs)
  l1-ecs-cluster: aws:ecs:cluster (2 inputs, 2 outputs)
  l1-ecs-service: aws:ecs:task_definition (10 inputs, 2 outputs)
  l1-iam-role: aws:iam:role (4 inputs, 2 outputs)
  l1-alb: aws:elbv2:loadbalancer (6 inputs, 3 outputs)
  l1-ecr: aws:ecr:repository (2 inputs, 2 outputs)
interface.json validation: OK
registry: OK (8 entries: 7 L1s + 1 L2)
TYPE_MAP: OK (12 IR types)
adapter.py: py_compile OK
S3 regression: OK (v1.1 spike l1-s3 adapts identically)
IR schema availability: OK (interface contracts have valid L1 shape)
.ciagent/ consistency: OK

=== Phase 13: VERIFIED ===

All assertions pass. The S3 regression check confirms the generalized adapter produces byte-identical main.tf for the v1.1 spike's l1-s3/spike_instance.json (resource block with bucket, versioning, bucket_arn/bucket_name outputs).

• PASS.

3. Security

• No credentials introduced. The L1 interfaces declare inputs/outputs only; no AWS key material.
• The adapter remains a thin translator — no hardcoded secrets, no IAM role assumptions.
• The spike_runner_policy.json (Phase 12) already grants the ECS/ECR/ELB/IAM/EC2 permissions these L1s will need for Phase 15's terraform apply.
• PASS.

4. Quality

• The adapter generalization preserves the v1.1 contract: S3 is the regression baseline, and its main.tf output is byte-identical (confirmed by the subagent's diff against the pre-edit baseline + the verify script's grep assertions).
• The 6 L1 interfaces follow the exact l1-s3 pattern (same JSON structure, same README sections with IR→Terraform mapping tables).
• Multi-resource L1s (l1-vpc, l1-ecs-service, l1-alb) use a resources array in interface.json to declare the grouped IR types — a clean extension of the single-resource pattern.
• The TYPE_MAP + INPUT_MAP + OUTPUT_MAP tables are the only substrate-specific code (per §12.2); the L1 content is substrate-agnostic.
• PASS.

P0 / P1

• P0: none.
• P1: none. The adapter handles the ECS task definition's container_definitions (a JSON string built from image/port/env) via a targeted transformation — not a hardcoded shape, but the one pragmatic mapping the plan called for.

Requirements covered

• REQ-31: Six new IR-typed L1 modules exist under modules-ir/l1/ and are registered in modules-ir/registry.json: l1-vpc (4 inputs, 3 outputs, IR types aws:ec2:vpc/subnet/routetable), l1-ecs-cluster (2/2, aws:ecs:cluster), l1-ecs-service (10/2, aws:ecs:task_definition + aws:ecs:service), l1-iam-role (4/2, aws:iam:role), l1-alb (6/3, aws:elbv2:loadbalancer/listener/targetgroup), l1-ecr (2/2, aws:ecr:repository). The adapter TYPE_MAP is expanded to 12 IR types. The v1.1 l1-s3 regression passes (byte-identical output). VERIFIED.

Conclusion

Phase 13 is VERIFIED. The L1 catalog is ready for Phase 14's l2-microservice thin-composition (which will reference these 6 L1s) and Phase 15's terraform apply (which will provision them). The adapter is now a clean table-driven translator — adding future L1s (v1.3+) is a matter of extending the three maps, not writing new emit logic.
