-# Phase 12 — nfr-harden-and-simplify (v1.2) PLAN
+# Phase 13 — l1-catalog-for-ecs (v1.2) PLAN
 
 ## Goal
 
-Apply Phase 11's NFR + simplification findings: tighten the spike IAM
-policy for the v1.2 ECS scope, consolidate the two `run_spike_*.sh`
-scripts into one `scripts/run_platform.sh` (D-048), redact the two AWS
-access key IDs from `.ciagent/` (P1-1), and fix the one stale `platform/`
-path in PERSONAS.md (P1-B). The v1.1 spike still runs e2e after the
-refactor.
+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.
 
 ## Tasks
 
-### Wave 1 (backend-engineer — scripts + IAM)
+### Wave 1 — Generalize the adapter (T-13.1, backend-engineer)
 
-#### T-12.1 — Consolidate run_spike_*.sh → run_platform.sh (D-048, REQ-30)
-- Create `scripts/run_platform.sh` with a `--plan-only` flag (default: full e2e).
-- Subsumes `run_spike_e2e.sh` (full pipeline) + `run_spike_plan.sh` (plan-only subset).
-- Use `set -euo pipefail` + `fail()` helper for uniform strictness.
-- Delete `run_spike_plan.sh` + `run_spike_e2e.sh`; update README.md to reference `run_platform.sh` only.
-- Territory: `scripts/run_platform.sh`, `scripts/run_spike_*.sh`, `README.md`
+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-12.2 — IAM policy expansion for ECS (REQ-30)
-- Update `terraform/bootstrap/spike_runner_policy.json` to add ECS + ECR + ELB + IAM plan/apply permissions (scoped to the spike resources, least-privilege).
-- Keep the `DenyEverythingElse` statement; expand the `NotResource` list.
-- Territory: `terraform/bootstrap/spike_runner_policy.json`
+### Wave 2 — 6 L1 modules + registry (T-13.2, backend-engineer, D-049)
 
-#### T-12.3 — Idempotency documentation (REQ-30)
-- Add a comment block to `create_state_backend.py` + `create_iam_user.py` documenting the idempotency contract (already idempotent per Phase 11 audit — no code change).
-- Territory: `terraform/bootstrap/create_state_backend.py`, `terraform/bootstrap/create_iam_user.py`
+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.
 
-### Wave 2 (docs — redactions + stale paths)
+| 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 |
 
-#### T-12.4 — Redact P1-1 AWS key IDs (REQ-30)
-- Replace the two v1.1 AWS access key IDs (rotated spike key + deactivated root key) → `AKIA…SPIKE` / `AKIA…ROOT-DEACTIVATED` in `.ciagent/RESEARCH.md`, `.ciagent/PROJECT.md`, `.ciagent/REVIEW.md`, `.ciagent/AUDIT.md`.
-- Territory: `.ciagent/`
+Multi-resource L1s (vpc, ecs-service, alb): `interface.json` declares the group's inputs/outputs + a `resources` array listing the IR types it emits.
 
-#### T-12.5 — Fix stale platform/ path in PERSONAS.md (P1-B, REQ-30)
-- Line 47: `platform/registry/**` → `modules-ir/registry.json`.
-- Territory: `.ciagent/PERSONAS.md`
+### 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
 
-- `scripts/run_platform.sh` runs the full v1.1 spike e2e and exits 0.
-- `scripts/run_platform.sh --plan-only` runs plan-only and exits 0.
-- `run_spike_plan.sh` + `run_spike_e2e.sh` no longer exist.
-- No live v1.1 AWS access key IDs remain anywhere in `.ciagent/` (fully redacted to placeholders).
-- `grep -rn "platform/registry" .ciagent/PERSONAS.md` returns nothing.
-- `spike_runner_policy.json` has ECS + ECR + ELB + IAM permissions.
-- `scripts/verify_phase12.sh` (authored in verify).
+- 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`.

 ## Scope
 
-Phase 12 applies Phase 11's NFR + simplification findings: consolidates
-the two `run_spike_*.sh` scripts into one `scripts/run_platform.sh`
-(D-048), expands the spike IAM policy for the v1.2 ECS scope
-(least-privilege), documents the bootstrap idempotency contract, redacts
-the two v1.1 AWS access key IDs from `.ciagent/` (P1-1), and fixes the
-last stale `platform/` path in PERSONAS.md (P1-B). Requirement covered:
-**REQ-30**.
+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
 
-- `scripts/run_platform.sh` exists (+x, supersedes the two v1.1 scripts).
-- `scripts/run_spike_e2e.sh` + `scripts/run_spike_plan.sh` deleted.
-- `terraform/bootstrap/spike_runner_policy.json` expanded (ECS + ECR + ELB + IAM + EC2 Allow statements; DenyEverythingElse NotResource expanded).
-- `terraform/bootstrap/create_state_backend.py` + `create_iam_user.py` have idempotency-contract docstrings (logic unchanged).
-- `README.md` references `run_platform.sh` (no stale `run_spike_*.sh` refs).
-- `.ciagent/RESEARCH.md`, `PROJECT.md`, `REVIEW.md`, `AUDIT.md` redacted (no live AWS key IDs).
-- `.ciagent/PERSONAS.md` line 47 fixed (`platform/registry/**` → `modules-ir/registry.json`).
-- `scripts/verify_phase12.sh` exists (+x).
-- `.ciagent/PLAN.md` updated to Phase 12.
+- 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.**

 ```
 
-All 22 assertions pass. Additionally, the subagent ran
-`bash scripts/run_platform.sh --plan-only` during execution and it
-completed all 4 plan steps against real AWS (`.env.secrets` present in
-this env), printed `=== PLATFORM PLAN OK ===`, exit 0 — the consolidated
-script is functionally equivalent to the original `run_spike_plan.sh`.
+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
 
-- **P1-1 closed**: no live AWS access key IDs remain in `.ciagent/` (`grep -rn "AKIAYOZHMKZ7RK26N66W\|AKIAYOZHMKZ772SINHFX" .ciagent/` returns nothing). The key IDs in git history (v1.1 commits) are immutable but the current-tree narrative is clean.
-- **IAM policy**: expanded to ECS/ECR/ELB/IAM/EC2 with region-scoped resource ARNs (`arn:aws:ecs:us-east-1:581513795199:*` etc.) — least-privilege, no `*` resources. `DenyEverythingElse` preserved with expanded `NotResource`. The policy is ready for Phase 15's `terraform apply` but grants no more than the ECS microservice needs.
-- **No credentials introduced**: the policy is a static JSON document; no secrets in code.
+- 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
 
-- `run_platform.sh` uses `set -euo pipefail` (strict bash) — stricter than the original `set -u`.
-- The `--plan-only` flag defaults to false (full e2e is the default), matching the v1.1 behavior where `run_spike_e2e.sh` was the primary entry point.
-- The IAM policy expansion follows the Phase 13 L1 catalog scoping (D-049): the 6 L1s map to exactly the 5 new permission categories (ECS, ECR, ELB, IAM, EC2).
-- The idempotency documentation is accurate (the scripts were already idempotent per the Phase 11 code audit — this phase documents the contract, no logic change).
+- 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 new.** P1-1 (carried from v1.1) is now **closed** by this phase. P1-B (stale `platform/` path) is now **closed**. P1-A (config.json status) was closed at `ab69d10` in v1.1. P1-C (run.md tag-placement guidance) and P1-D (ROADMAP audit-pending) were closed in v1.1.
+- **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-30:** NFR hardening — (a) `spike_runner_policy.json` expanded to least-privilege ECS/ECR/ELB/IAM/EC2 (audit-ready, no wildcards beyond documented exceptions); (b) `create_state_backend.py` + `create_iam_user.py` idempotency documented (already idempotent); (c) `run_spike_plan.sh` + `run_spike_e2e.sh` consolidated into `scripts/run_platform.sh` with `set -euo pipefail` + `--plan-only` flag; (d) P1-1 redacted (no live AWS key IDs in `.ciagent/`); (e) P1-B fixed (no stale `platform/` paths). **VERIFIED.**
+- **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 12 is VERIFIED. The platform is hardened and simpler: one
-`run_platform.sh` instead of two scripts, least-privilege IAM ready for
-ECS, idempotency documented, and the v1.1 audit's P1-1 + P1-B hygiene
-items are closed. The v1.1 spike still runs e2e after the refactor
-(verified by the subagent's `--plan-only` run against real AWS).

+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.

+# l1-alb — Application Load Balancer primitive (multi-resource L1)
+
+An L1 module for an Application Load Balancer (load balancer + target
+group + listener). Substrate-agnostic (the IR types are
+`aws:elbv2:loadbalancer`, `aws:elbv2:listener`, `aws:elbv2:targetgroup`,
+not Terraform resource types). This is a multi-resource L1: the
+interface declares the group's inputs/outputs plus a `resources` array
+listing the IR types it emits. The IR instance (Phase 14/15) will have
+multiple `resources` entries all with `module: "l1-alb@1.0.0"`.
+
+## Interface (the IR-typed contract)
+
+See `interface.json`: inputs `name` (string), `subnets` (string,
+comma-separated, ref to l1-vpc), `security_group` (string), `port`
+(number, default 80), `protocol` (string, default "HTTP"), `region`
+(string); outputs `lb_arn` (arn) + `listener_arn` (arn) +
+`target_group_arn` (arn); no NFRs.
+
+The `resources` array lists the emitted IR types:
+
+- `aws:elbv2:loadbalancer` — application load balancer in the VPC
+  subnets.
+- `aws:elbv2:targetgroup` — target group for the ECS service tasks.
+- `aws:elbv2:listener` — listener forwarding the LB port to the target
+  group.
+
+## IR → Terraform mapping (performed by the adapter)
+
+The Terraform adapter (`adapters/terraform/adapter.py`) translates each
+emitted IR resource to Terraform:
+
+| IR | Terraform |
+|----|-----------|
+| `resource.type = aws:elbv2:loadbalancer` | `resource "aws_lb" "<id>" { ... }` |
+| `resource.inputs.name` | `name = <value>` arg |
+| `resource.inputs.subnets` | `subnets = [<value>]` arg (comma-split) |
+| `resource.inputs.security_group` | `security_groups = [<value>]` arg (comma-split) |
+| `resource.outputs.lb_arn` | `output "lb_arn" { value = aws_lb.<id>.id }` |
+| `resource.type = aws:elbv2:targetgroup` | `resource "aws_lb_target_group" "<id>" { ... }` |
+| `resource.inputs.port` | `port = <value>` arg |
+| `resource.inputs.protocol` | `protocol = <value>` arg |
+| `resource.outputs.target_group_arn` | `output "target_group_arn" { value = aws_lb_target_group.<id>.arn }` |
+| `resource.type = aws:elbv2:listener` | `resource "aws_lb_listener" "<id>" { ... }` |
+| `resource.inputs.lb_arn` | `load_balancer_arn = <value>` arg (identity) |
+| `resource.inputs.port` | `port = <value>` arg |
+| `resource.inputs.protocol` | `protocol = <value>` arg |
+| `resource.outputs.listener_arn` | `output "listener_arn" { value = aws_lb_listener.<id>.id }` |
+
+The adapter is a thin layer (ARCHITECTURE.md §12.2); it does not own L1
+content — it only translates.
+
+## Versioning (W3.D)

+Single-purpose, substrate-agnostic (the IR type is `aws:iam:role`, not a
+Terraform resource type).
+
+## Interface (the IR-typed contract)
+
+See `interface.json`: inputs `role_name` (string), `assume_role_policy`
+(JSON string), `managed_policies` (optional comma-separated ARNs),
+`region` (string); outputs `role_arn` (arn) + `role_id` (string), no
+NFRs.
+
+## IR → Terraform mapping (performed by the adapter)
+
+The Terraform adapter (`adapters/terraform/adapter.py`) translates this
+L1's IR shape to Terraform:
+
+| IR | Terraform |
+|----|-----------|
+| `resource.type = aws:iam:role` | `resource "aws_iam_role" "<id>" { ... }` |
+| `resource.inputs.role_name` | `name = <value>` arg |
+| `resource.inputs.assume_role_policy` | `assume_role_policy = <value>` arg (JSON string) |
+| `resource.inputs.managed_policies` | `managed_policy_arns = [<arns>]` arg (comma-split) |
+| `resource.inputs.region` | `provider "aws" { region = <value> }` |
+| `resource.outputs.role_arn` | `output "role_arn" { value = aws_iam_role.<id>.arn }` |
+| `resource.outputs.role_id` | `output "role_id" { value = aws_iam_role.<id>.id }` |
+
+The adapter is a thin layer (ARCHITECTURE.md §12.2); it does not own L1
+content — it only translates.
+
+## 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.

+# l1-vpc — VPC primitive (multi-resource L1)
+
+An L1 module for a VPC with subnets and a route table. Substrate-agnostic
+(the IR types are `aws:ec2:vpc`, `aws:ec2:subnet`, `aws:ec2:routetable`,
+not Terraform resource types). This is a multi-resource L1: the
+interface declares the group's inputs/outputs plus a `resources` array
+listing the IR types it emits. The IR instance (Phase 14/15) will have
+multiple `resources` entries all with `module: "l1-vpc@1.0.0"`.
+
+## Interface (the IR-typed contract)
+
+See `interface.json`: inputs `cidr` (string, e.g. "10.0.0.0/16"), `azs`
+(string, comma-separated, e.g. "us-east-1a,us-east-1b"), `name` (string,
+used for tagging), `region` (string); outputs `vpc_id` (string),
+`subnet_ids` (string, comma-separated), `igw_id` (string); no NFRs.
+
+The `resources` array lists the emitted IR types:
+
+- `aws:ec2:vpc` — the VPC itself (cidr → cidr_block, name → tag).
+- `aws:ec2:subnet` — one subnet per availability zone (`azs` split on
+  comma); inputs include the parent VPC id.
+- `aws:ec2:routetable` — route table bound to the VPC with an internet
+  gateway + default route (0.0.0.0/0 → igw).
+
+## IR → Terraform mapping (performed by the adapter)
+
+The Terraform adapter (`adapters/terraform/adapter.py`) translates each
+emitted IR resource to Terraform:
+
+| IR | Terraform |
+|----|-----------|
+| `resource.type = aws:ec2:vpc` | `resource "aws_vpc" "<id>" { ... }` |
+| `resource.inputs.cidr` | `cidr_block = <value>` arg |
+| `resource.inputs.name` | `tags = { Name = <value> }` (emit as-is) |
+| `resource.outputs.vpc_id` | `output "vpc_id" { value = aws_vpc.<id>.id }` |
+| `resource.type = aws:ec2:subnet` | `resource "aws_subnet" "<id>" { ... }` |
+| `resource.inputs.cidr` | `cidr_block = <value>` arg |
+| `resource.inputs.az` | `availability_zone = <value>` arg |
+| `resource.outputs.subnet_id` | `output "subnet_id" { value = aws_subnet.<id>.id }` |
+| `resource.type = aws:ec2:routetable` | `resource "aws_route_table" "<id>" { ... }` |
+| `resource.inputs.vpc_id` | `vpc_id = <value>` arg |
+
+The internet gateway + default route are emitted as part of the route
+table resource's IR (the `igw_id` output is wired via the route table's
+inputs). The adapter is a thin layer (ARCHITECTURE.md §12.2); it does
+not own L1 content — it only translates.
+
+## 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.
