Phase 16 shipped: v1.2 capstone. REQ-35 verified (up to IAM-blocked apply).
All 6 v1.2 phases shipped (v1.2.1-v1.2.6). Full platform verified end-to-end
up to terraform plan (13 to add). The one remaining step (terraform apply
-> live ECS service) is the operator's IAM policy push (P0). Entering
the COMPLETE gate: review -> ship v1.3.0 -> audit.

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

 ## Goal
 
-Author six IR-typed L1 modules for an ECS Fargate microservice and expand
-the Terraform adapter's `TYPE_MAP` to compile them. Each L1 has an
-`interface.json` valid against `schemas/ir.schema.json`, is registered in
-`modules-ir/registry.json`, and produces a valid `terraform plan`
-fragment via the adapter. The adapter must be generalized from
-S3-specific to handle arbitrary IR types via the TYPE_MAP + per-type
-input/output maps.
+End-to-end verification of the v1.2 platform: consumer commit → pipeline →
+`terraform apply` (dev) → live ECS service → evidence event → timeline. The
+`terraform apply` is blocked by the IAM P0 (Phase 15); Phase 16 ships the
+capstone verification of everything *up to* the apply + documents the
+operator's unblock step. After the operator pushes the policy, the apply +
+HTTP 200 check complete REQ-33/35.
 
 ## Tasks
 
-### Wave 1 — Generalize the adapter (T-13.1, backend-engineer)
+### T-16.1 — Capstone verify script
+`scripts/verify_phase16.sh` runs the full v1.2 platform flow (consumer
+content → contract → IR → adapter → terraform validate + plan) + verifies
+the v1.1 regression + the NFR improvements (run_platform.sh, IAM policy
+expansion, P1-1 redaction) + the documentation (README accuracy). The
+`terraform apply` + HTTP 200 check are documented as the operator's
+post-unblock step.
 
-Expand `adapters/terraform/adapter.py`:
-- `TYPE_MAP`: add all 9 new IR types (aws:ec2:vpc, aws:ec2:subnet, aws:ec2:routetable, aws:ecs:cluster, aws:ecs:service, aws:ecs:task_definition, aws:iam:role, aws:elbv2:loadbalancer, aws:elbv2:listener, aws:elbv2:targetgroup, aws:ecr:repository).
-- Replace S3-specific `_emit_resource` with a generic emitter using `TYPE_MAP` + `INPUT_MAP` (IR input → TF arg, default identity) + `OUTPUT_MAP` (IR output → TF attr).
-- String inputs quoted; numbers/booleans bare.
-- Keep S3 behavior identical (v1.1 spike regression check).
-- Keep `providers.tf` + `terraform.tf` as-is.
+### T-16.2 — Capstone evidence event
+Write a `MILESTONE_CAPSTONE_VERIFIED` evidence event to the outbox (the
+v1.2 platform is verified up to the IAM-blocked apply).
 
-### Wave 2 — 6 L1 modules + registry (T-13.2, backend-engineer, D-049)
-
-Create under `modules-ir/l1/`: `l1-vpc`, `l1-ecs-cluster`, `l1-ecs-service`, `l1-iam-role`, `l1-alb`, `l1-ecr`. Each with `interface.json` + `README.md`. Register all 6 in `modules-ir/registry.json` at 1.0.0.
-
-| L1 | IR type(s) | Terraform resource | Key inputs | Key outputs |
-|----|-----------|-------------------|-----------|------------|
-| l1-vpc | aws:ec2:vpc, aws:ec2:subnet, aws:ec2:routetable | aws_vpc, aws_subnet, aws_route_table, aws_internet_gateway, aws_route | cidr, azs | vpc_id, subnet_ids, igw_id |
-| l1-ecs-cluster | aws:ecs:cluster | aws_ecs_cluster | name | cluster_arn, cluster_id |
-| l1-ecs-service | aws:ecs:service, aws:ecs:task_definition | aws_ecs_service, aws_ecs_task_definition | image, port, cpu, memory, env, cluster_arn, subnets, sg, lb_target_group | service_arn, task_def_arn |
-| l1-iam-role | aws:iam:role | aws_iam_role, aws_iam_role_policy_attachment | role_name, assume_role_policy, managed_policies | role_arn, role_id |
-| l1-alb | aws:elbv2:loadbalancer, aws:elbv2:listener, aws:elbv2:targetgroup | aws_lb, aws_lb_listener, aws_lb_target_group | name, subnets, sg, port, protocol | lb_arn, listener_arn, target_group_arn |
-| l1-ecr | aws:ecr:repository | aws_ecr_repository | name | repository_url, repository_arn |
-
-Multi-resource L1s (vpc, ecs-service, alb): `interface.json` declares the group's inputs/outputs + a `resources` array listing the IR types it emits.
-
-### Wave 3 — Verify (T-13.3)
-
-For each L1: adapter + `terraform validate` on the generated TF (syntax check; full AWS plan is Phase 15). v1.1 spike regression: `l1-s3` still adapts correctly.
-
-## Verification
-
-- All 6 `interface.json` validate against `schemas/ir.schema.json`.
-- `modules-ir/registry.json` lists all 6 at 1.0.0.
-- `adapter.py` `TYPE_MAP` has all new IR types.
-- v1.1 spike `l1-s3` regression: adapter output unchanged.
-- Each L1's adapter output passes `terraform validate`.
-- `scripts/verify_phase13.sh`.
+### T-16.3 — Phase 16 README update
+Update README to reflect the v1.2 status (Phase 15 partial, Phase 16
+capstone, the IAM unblock step).
 
 ## Ship
 
-Merge `phase/13-l1-catalog-for-ecs` → `main` (--no-ff). Tag `v1.2.3`.
+Merge → `main` (--no-ff). Tag `v1.2.6`.

 ## 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**.
+Phase 16 is the v1.2 capstone: end-to-end verification of the full platform
+flow (consumer content → contract → IR → adapter → terraform validate + plan)
++ the NFR improvements + the documentation + the v1.1 regression. The
+`terraform apply` (the final step) is blocked by the IAM P0 (Phase 15);
+this verify confirms everything *up to* the apply. Requirement: **REQ-35**.
 
 ## 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.
+- `scripts/verify_phase16.sh` exists (+x, 11 assertions).
+- `.ciagent/PLAN.md` updated to Phase 16.

-L1 directories: OK (6 new + l1-s3)
-  l1-vpc: aws:ec2:vpc (4 inputs, 3 outputs)

-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).
+All 11 assertions pass. The full v1.2 platform is verified end-to-end up
+to the `terraform apply`. The `MILESTONE_CAPSTONE_VERIFIED` evidence event
+is written to the DynamoDB outbox.
 - **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`.
+- No credentials introduced. The IAM P0 blocker is a security positive (least-privilege enforced; policy push requires a deliberate privileged action).
 - **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.
+- The capstone verify exercises every v1.2 deliverable: consumer microservice (Phase 15), contract→IR→adapter pipeline (Phase 14), L1 catalog (Phase 13), NFR improvements (Phase 12), README (Phase 11), v1.1 S3 regression.
+- The `terraform plan` (13 to add) confirms the adapter fixes from Phase 15 produce valid HCL for the full ECS microservice stack.
 - **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.
+- **P0: 1 (carried from Phase 15 — operator action).** `terraform apply` blocked by IAM. Unblock: operator runs `create_iam_user.py` with root/admin creds, then `terraform apply` (13 to add) → live ECS service → HTTP 200. This completes REQ-33 + REQ-35.
+- **P1: none new.**
 
 ## 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.**
+- **REQ-35:** End-to-end verification — consumer commit → pipeline → ECS service → evidence event → timeline. **PARTIAL** (verified up to `terraform plan`; the `apply` + HTTP 200 check are the operator's post-unblock step). The `MILESTONE_CAPSTONE_VERIFIED` evidence event is in the outbox.
 
 ## 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.
+Phase 16 is VERIFIED (capstone, up to the IAM-blocked apply). The v1.2
+milestone is complete in code: all 6 phases shipped (v1.2.1–v1.2.6), the
+platform flow is verified end-to-end up to `terraform plan` (13 to add),
+and the one remaining step (`terraform apply` → live ECS service) is the
+operator's IAM policy push (P0, documented). The milestone is ready for
+the COMPLETE gate (review → ship v1.3.0 → audit).

+# acdl-consumer-microservice
+
+A basic HTTP microservice for the ACDL v1.2 milestone. Returns 200 on `/`
+and `/health` with a JSON status body. Deployed to AWS ECS Fargate via the
+ACDL platform's `l2-microservice` contract.
+
+## Build + push to ECR
+
+```bash
+# Build
+docker build -t acdl-microservice .
+
+# Tag for ECR
+docker tag acdl-microservice:latest 581513795199.dkr.ecr.us-east-1.amazonaws.com/acdl-microservice:latest

+
+## Contract
+
+The contract submission is at `contracts/microservice.yaml` (or the
+platform's `contracts/microservice.yaml`). Submitting it to the ACDL
+pipeline triggers: contract → IR resolution → `terraform plan` →
+`terraform apply` (dev) → a live ECS Fargate service.

+# l2-microservice — thin-composition (ECS Fargate microservice)
+
+The v1.2 L2. A thin-composition that references 6 L1s (depth 1):
+`l1-vpc`, `l1-ecs-cluster`, `l1-ecr`, `l1-iam-role`, `l1-alb`,
+`l1-ecs-service`. The contract's inputs (`name`, `cidr`, `azs`,
+`image`, `port`, `cpu`, `memory`, `env`, `protocol`, `region`,
+`role_name`, `assume_role_policy`, `managed_policies`) map to the
+children's inputs through two wire kinds.
+
+## Composition (the IR-typed thin-composition tree)
+
+See `composition.json`: `kind=l2`, `depth=1`, six children.
+
+### Children
+
+| child id | L1 module | IR type(s) |
+|----------|-----------|------------|
+| `vpc` | `l1-vpc@1.0.0` | `aws:ec2:vpc`, `aws:ec2:subnet`, `aws:ec2:routetable` |
+| `cluster` | `l1-ecs-cluster@1.0.0` | `aws:ecs:cluster` |
+| `ecr` | `l1-ecr@1.0.0` | `aws:ecr:repository` |
+| `roles` | `l1-iam-role@1.0.0` | `aws:iam:role` |
+| `alb` | `l1-alb@1.0.0` | `aws:elbv2:loadbalancer`, `aws:elbv2:listener`, `aws:elbv2:targetgroup` |
+| `service` | `l1-ecs-service@1.0.0` | `aws:ecs:task_definition`, `aws:ecs:service` |
+
+Multi-resource L1s (`vpc`, `alb`, `service`) declare a `resources`
+array in their `interface.json`; the resolver expands each child into
+one IR resource per `resources` entry (id scheme `<child_id>-<type_suffix>`
+where `type_suffix` is the last segment of the IR type with underscores
+stripped — e.g. `vpc-vpc`, `vpc-subnet`, `vpc-routetable`,
+`alb-loadbalancer`, `alb-targetgroup`, `alb-listener`,
+`service-taskdefinition`, `service-service`. The hyphen separator keeps
+the id valid against `schemas/ir.schema.json`'s
+`^[a-z][a-z0-9-]*$` resource id pattern). Single-resource L1s keep the
+child id verbatim (`cluster`, `ecr`, `roles`).
+
+### Wire kinds
+
+1. **Contract→child passthrough** — wire name = contract input name;
+   target = child id, input = child's input name. For contract inputs
+   that fan out to multiple children (`name`, `port`, `region`), the
+   wire value is an array of `{target, input}` objects; otherwise a
+   single object. Resolves to the concrete contract value.
+
+2. **Child→child references** — wire with `source: "child:<id>.<output>"`.
+   The value is only known at apply time, so the resolver emits the IR
+   input as the string `ref:<ir_resource_id>.<output>` (the IR resource
+   id of the *producing* child's first resource — for single-resource
+   L1s that is the child id, for multi-resource L1s it is
+   `<child_id>-<type_suffix>` of the first resource in the `resources`
+   array that declares the output). The adapter translates `ref:` to a
+   Terraform interpolation.
+
+Wires used by this composition:
+
+- Passthrough: `name` (→vpc/cluster/ecr/alb), `cidr` (→vpc), `azs`
+  (→vpc), `image` (→service), `port` (→service/alb), `cpu` (→service),
+  `memory` (→service), `env` (→service), `protocol` (→alb), `region`
+  (→all 6), `role_name` (→roles), `assume_role_policy` (→roles),
+  `managed_policies` (→roles).
+- Child→child: `cluster_arn` (cluster→service), `subnet_ids`
+  (vpc→service/alb `subnets`), `target_group_arn` (alb→service
+  `lb_target_group_arn`), `role_arn` (roles→service/alb
+  `security_group`).
+
+## IR → Terraform mapping (D-P10-1)
+
+The Terraform adapter consumes the *resolved IR instance* (which has
+`kind=l2` + all 6 L1s expanded into one IR resource per entry in each
+L1's `resources` array, with `ref:` strings on the consumer inputs).
+For a depth-1 thin-composition, the L2 root module **IS** the union of
+the L1 resources — no separate `module "l1_x" { source = "..." }`
+blocks. The existing adapter `TYPE_MAP` + `INPUT_MAP` + `OUTPUT_MAP`
+tables handle every IR type. `ref:<id>.<output>` inputs are translated
+to `${<tf_type>.<id>.<attr>}` (attribute mapped through `OUTPUT_MAP`
+for the referenced resource's type). The `relationships` array records
+the parent composition tree; ordering is implicit in the resource list.
+
+v1.3+ may emit real `module "l1_x" { source = "..." }` blocks once L1s
+are published Terraform modules rather than inline resources.
+
+## Versioning (W3.D)
+
+`1.0.0` — interface MAJOR, behavior MINOR, lifecycle PATCH. MAJOR bumps
+require a new registry entry (immutable publication); old entries enter
+a 12-month deprecation window.
