This file documents the > technical findings that ground the v1.11 restart plan. --- ## Background — why v1.11 is a restart v1.11 is a **restart**, not a continuation. The first attempt (phase/56 + phase/57, abandoned per D-097) made five defects worse, not better. The restart branches off the clean `v1.10.2` tag and corrects three structural defects that the CLARIFY stage locked as binding decisions: 1. **Stateless adapter** (D-098, D-099, D-100). The current adapter is a 750-line monolith with 3 constant tables and 39 type-specific branches that duplicate what `interface.json` already declares and hardcode defaults that belong in the module. v1.11 makes it a ~80-line stateless assembler; each L1 ships a real `terraform/` module dir that owns its resource shape, nested blocks, and defaults. 2. **Terraform owns lifecycle** (D-101). The first attempt added a Python script (`verify_deploy_microservice.py`) that ran `terraform init -reconfigure` in a fresh temp dir each time, which contributed to the 4-VPC bug. v1.11 deletes that script; `run_platform.sh` gains `--apply` and `--destroy` modes; Python never runs terraform. 3. **Pipeline-driven testing** (D-102, D-103, D-104). No per-module Python/pytest. A modules-lifecycle pipeline matrix-runs each L1 module's `examples/{simple,complex}.yml` contracts through apply→modify→destroy against live AWS. The "test" = the pipeline cell going green. --- ## FINDING 1 — Adapter monolith audit ### 1.1 The three constant tables `adapters/terraform/adapter.py` (750 lines on the v1.10.2 tree) is built around three constant tables: | Table | Line | What it encodes | Entries | |-------|------|-----------------|---------| | `TYPE_MAP` | 26 | Stack type (`aws::`) → Terraform resource type (`aws_s3_bucket`, `aws_vpc`, …). | 19 | | `INPUT_MAP` | 51 | Stack input name → Terraform arg name, per stack type. Only non-identity mappings are listed; an input not present uses the stack name as the Terraform arg (identity). | 19 (one per stack type) | | `OUTPUT_MAP` | 75 | Stack output name → Terraform attribute name, per stack type. Only non-identity mappings. | 19 (one per stack type) | **Why they duplicate `interface.json`.** Each L1 module already declares its inputs, outputs, and stack type in `interface.json` (engine-agnostic). The three tables are the *engine binding* — the Terraform-specific name mappings that `interface.json` deliberately omits (it is engine-agnostic per ARCHITECTURE.md §12). The duplication is therefore *intentional in the original design*: the adapter was meant to be a thin translator that holds the engine binding in three tables, and the L1 holds the engine-agnostic content. **The drift.** What was *not* intended is that the tables grew into 39 type-specific branches (§1.2) that hardcode resource shapes, nested HCL blocks, and defaults (§1.3) — content that belongs in the module, not the adapter. The adapter stopped being a thin translator and became a per-resource-type code generator. D-098 corrects this: the engine binding moves into a per-module `terraform/` subdir (the real Terraform module), and the adapter becomes a stateless assembler that emits `module "x" { source = "..." ... }` blocks. The three tables are deleted. ### 1.2 The 39 type-specific branches across 18 stack types `_emit_resource` (line 156) is a generic loop that, for each input, looks up the Terraform arg in `INPUT_MAP`, renders the value, and appends `arg = value`. But 18 of the 19 stack types have a *specialized branch* inside `_emit_resource` that runs after the generic loop and emits nested HCL blocks, hardcoded defaults, or resource-specific wiring. The count of 39 branches is the sum of the per-type specializations (some types have 2–3 branches). The full inventory: | # | Stack type | Terraform type | Specialized logic (what the branch does) | |---|-----------|----------------|------------------------------------------| | 1 | `aws:s3:bucket` | `aws_s3_bucket` | `versioning {}` block (default true); `server_side_encryption_configuration {}` block (SSE-KMS, CMK ref or managed-key fallback with stderr warning); `kms_key_arn` is not a bare arg — emitted as the SSE block. | | 2 | `aws:ec2:vpc` | `aws_vpc` | `tags { Name = ... }` from the `name` input; hardcoded `cidr_block = "10.0.0.0/16"` default when the L2 doesn't supply a CIDR (line 288). | | 3 | `aws:ec2:subnet` | `aws_subnet` | `vpc_id = aws_vpc.vpc-vpc.id` hardcoded ref when not in inputs; hardcoded `cidr_block = "10.0.1.0/24"` default (line 296); `tags { Name = ... }`. | | 4 | `aws:ec2:routetable` | `aws_route_table` | `vpc_id = aws_vpc.vpc-vpc.id` hardcoded ref; `route { cidr_block = "0.0.0.0/0" gateway_id = aws_internet_gateway.vpc-igw.id }` hardcoded default route; `tags { Name = "-rt" }`. | | 5 | `aws:ecs:cluster` | `aws_ecs_cluster` | Hardcoded `name = "acdl-microservice"` default when not in inputs (line 300). | | 6 | `aws:ecs:task_definition` | `aws_ecs_task_definition` | `_container_definitions()` helper: jsonencodes `image`/`port`/`env` into a `container_definitions` block; hardcoded `family = "app"` default (line 279). | | 7 | `aws:ecs:service` | `aws_ecs_service` | `network_configuration {}` block (subnets + security_groups wrapped in list brackets); `load_balancer {}` block from `lb_target_group_arn` with hardcoded `container_name = "app"` + `container_port = 8080`; hardcoded `desired_count = 1`, `launch_type = "FARGATE"`, `task_definition = aws_ecs_task_definition.service-task-definition.arn`, `name = "acdl-microservice"`. | | 8 | `aws:iam:role` | `aws_iam_role` | `managed_policy_arns = [...]` from comma-separated string; hardcoded ECS task execution `assume_role_policy` JSON when not supplied (line 326–331); hardcoded `name = "acdl-microservice-role"` default. | | 9 | `aws:elbv2:loadbalancer` | `aws_lb` | `subnets`/`security_group` wrapped in list brackets; hardcoded `load_balancer_type = "application"` default. | | 10 | `aws:elbv2:listener` | `aws_lb_listener` | `default_action { type = "forward" target_group_arn = aws_lb_target_group.alb-targetgroup.arn }` hardcoded; `load_balancer_arn = aws_lb.alb-loadbalancer.id` hardcoded ref. | | 11 | `aws:elbv2:targetgroup` | `aws_lb_target_group` | Hardcoded `target_type = "ip"`, `vpc_id = aws_vpc.vpc-vpc.id`, `protocol = "HTTP"`, `port = 8080`. | | 12 | `aws:ecr:repository` | `aws_ecr_repository` | Hardcoded `name = "acdl-microservice"` default; `encryption_configuration {}` block (not a bare `kms_key_arn` arg). | | 13 | `aws:cloudfront:distribution` | `aws_cloudfront_distribution` | `origin {}` block (origin_id, domain_name, origin_access_control_id, `s3_origin_config {}`); `default_cache_behavior {}` block (viewer_protocol_policy, target_origin_id, ttls, allowed/cached methods); `enabled = true`; `price_class`; `restrictions { geo_restriction {} }`; `viewer_certificate { cloudfront_default_certificate = true }`; `web_acl_id` from WAF ref. ~8 nested blocks. | | 14 | `aws:cloudfront:originaccesscontrol` | `aws_cloudfront_origin_access_control` | `name`; hardcoded `origin_access_control_origin_type = "s3"`, `signing_behavior = "always"`, `signing_protocol = "sigv4"`. | | 15 | `aws:wafv2:webacl` | `aws_wafv2_web_acl` | `name`; hardcoded `scope = "CLOUDFRONT"`; `default_action {}` (allow/block from input, default allow); `visibility_config {}`; custom `rule {}` blocks as nested HCL (P1-4 fix) or default AWS-managed-rules block. ~5 nested blocks. | | 16 | `aws:rds:instance` | `aws_db_instance` | NFR-derived `backup_retention_period` (default 7), `deletion_protection` (default true); `storage_encrypted = true` default; `skip_final_snapshot = true` (dev safety). | | 17 | `aws:kms:key` | `aws_kms_key` | NFR-derived `enable_key_rotation = true` default. | | 18 | `aws:ecs:uptime-service` | `aws_ecs_service` | Feature-flag gate (returns `""` when disabled); `container_definitions` jsonencode for uptime-kuma; hardcoded `subnets = ["subnet-uptime"]`, `security_groups = ["sg-uptime"]`, `assign_public_ip = true`; hardcoded `desired_count = 1`, `launch_type = "FARGATE"`. | Plus a global `prevent_destroy` lifecycle block emitted for every resource when `nfrs.deletion_protection` is true (line 576–581), and the `_emit_igw()` helper that synthesizes an internet gateway + route table association from the VPC resource (line 585). ### 1.3 Hardcoded defaults that belong in the module The defaults below are emitted by the adapter when the L2 composition does not supply the input. They are *resource shape* decisions — CIDR ranges, trust policies, network config — that belong in the module's `locals.tf` (D-100), not in the adapter. The adapter should pass only resolved contract inputs; if a default is wrong, fix the module, not the adapter. | Default | Adapter line | What it is | Where it belongs | |---------|-------------|------------|------------------| | `cidr_block = "10.0.0.0/16"` | 288 | VPC CIDR default | `modules/l1/vpc/terraform/locals.tf` | | `cidr_block = "10.0.1.0/24"` | 296 | Subnet CIDR default | `modules/l1/vpc/terraform/locals.tf` | | ECS task execution `assume_role_policy` JSON | 326–331 | Trust policy for the IAM role | `modules/l1/iam-role/terraform/main.tf` (or `locals.tf`) | | ECR/logs inline policy / `encryption_configuration {}` | 304–315, 380 | ECR KMS encryption block | `modules/l1/ecr/terraform/main.tf` | | Fargate `requires_compatibilities` / `launch_type = "FARGATE"` | 261–263 | ECS launch config | `modules/l1/ecs-service/terraform/locals.tf` | | `assign_public_ip` (uptime) | 565 | ECS network config | `modules/l1/uptime/terraform/main.tf` | | Listener/target ports (`port = 8080`, `container_port = 8080`) | 201, 348 | ALB + ECS container ports | `modules/l1/alb/terraform/locals.tf` + `modules/l1/ecs-service/terraform/locals.tf` | | Security group emission (`security_groups = [...]`) | 255–258, 564 | ECS network config | `modules/l1/ecs-service/terraform/main.tf` | | `name = "acdl-microservice"` (cluster, ECR, service) | 265, 300, 303 | Resource name defaults | `modules/l1/*/terraform/locals.tf` | | `family = "app"` | 279 | Task definition family | `modules/l1/ecs-service/terraform/locals.tf` | | `target_type = "ip"`, `protocol = "HTTP"` | 345, 347 | ALB target group defaults | `modules/l1/alb/terraform/locals.tf` | | `load_balancer_type = "application"` | 342 | ALB type default | `modules/l1/alb/terraform/locals.tf` | | `desired_count = 1` | 260 | ECS desired count | `modules/l1/ecs-service/terraform/locals.tf` | | WAF `scope = "CLOUDFRONT"`, managed-rules default block | 421, 472–490 | WAF defaults | `modules/l1/waf/terraform/main.tf` | | CloudFront `signing_behavior = "always"`, `signing_protocol = "sigv4"`, `origin_type = "s3"` | 365–367 | OAC defaults | `modules/l1/cloudfront/terraform/main.tf` | | CloudFront `viewer_certificate { cloudfront_default_certificate = true }`, `restrictions {}` | 403–410 | Distribution defaults | `modules/l1/cloudfront/terraform/main.tf` | | RDS `backup_retention_period = 7`, `skip_final_snapshot = true` | 497, 506 | RDS defaults | `modules/l1/rds/terraform/locals.tf` | | KMS `enable_key_rotation = true` | 510 | KMS rotation default | `modules/l1/kms-key/terraform/main.tf` | | `prevent_destroy = true` lifecycle (global) | 576–581 | Deletion protection | Each module's `main.tf` (or a shared `lifecycle.tf`) | ### 1.4 Why this is a drift from the original vision ARCHITECTURE.md §12.2 states: *"The adapter is a thin layer; it does not own L1/L2 content — it only translates."* STANDARDS.md §8 (line 448–506) documents the intended design: "a thin translator with 3 tables + specialized branches." The drift was **baked into the standards doc itself** — §8.2 explicitly blesses "specialized `_emit_resource` branches" for "resources with nested HCL blocks" and §8.3 step 4 instructs module authors to "add a specialized branch in `_emit_resource` keyed on that stack type" when a new L1 needs nested blocks. The result: every new L1 with a nested block (CloudFront, WAF, ECS, uptime) added 30–80 lines of resource-shape code to the adapter. The adapter grew from a spike-era ~150 lines to 750 lines, with the resource shape (CIDR ranges, trust policies, container ports, managed-rule sets) encoded as Python string concatenation rather than Terraform HCL. D-098 corrects the drift: the standards doc §8 must be rewritten to document the new pattern (per-module `terraform/` subdir + stateless assembler), and the "specialized branch" guidance is removed. **Confidence: 0.95.** The audit is a direct line-by-line read of the v1.10.2 `adapter.py`; the drift is structural and unambiguous. --- ## FINDING 2 — State-key root cause of the 4-VPC bug ### 2.1 The state key `adapter.py` line 664 + 676: ```python stack_name = stack.get("name", "spike") terraform_tf = ( ... f' key = "spike/{stack_name}/terraform.tfstate"\n' ... ) ``` `core/contract_resolver.py` line 569: ```python "stack": { "name": contract["id"], ... } ``` So `stack_name = contract["id"]` and the state key is `spike/{contract.id}/terraform.tfstate`. ### 2.2 The 5 microservice contracts All five microservice contracts share `id: msvc` and differ only in `environment`: | Contract file | `id` | `environment` | |---------------|------|----------------| | `contracts/microservice.yml` | `msvc` | `dev` | | `contracts/microservice.dev.yml` | `msvc` | `dev` | | `contracts/microservice.qa.yml` | `msvc` | `qa` | | `contracts/microservice.prod.yml` | `msvc` | `prod` | | `contracts/microservice.dr.yml` | `msvc` | `dr` | The state key does **not** include the environment. So all four environment contracts (dev/qa/prod/dr) collide on the same state key: `spike/msvc/terraform.tfstate`. ### 2.3 The two root causes **Root cause 1 — the adapter emits per-contract state keys with no VPC sharing.** The `microservice` composition (`modules/l2/microservice/ composition.json`) includes a `vpc` child (`vpc@1.0.0`). Every contract that resolves through this composition emits its own VPC resource. There is no platform VPC to share; each contract deploys its own VPC. D-105 corrects this: `terraform/platform` owns ONE VPC; the microservice composition drops its `vpc` child and references the platform VPC via a data source. The standalone `vpc` L1 module stays (consumers deploy their own VPCs). No per-contract VPC ever again. **Root cause 2 — the state key does not distinguish environments.** Because the state key is `spike/{contract.id}/terraform.tfstate` and all four env contracts share `id: msvc`, every environment's `terraform apply` writes to the same remote state key. Combined with the first attempt's `verify_deploy_microservice.py` running `terraform init -reconfigure` in a **fresh temp dir each time**, each run created a fresh local state that diverged from the remote key. The first run (dev) created VPC #1 and pushed it to `spike/msvc/terraform.tfstate`. The second run (qa) ran `-reconfigure` in a fresh temp dir, pulled the remote state (which had dev's VPC), but because the local state was fresh and the composition emitted a *new* VPC resource address, terraform saw the VPC as "to add" again — creating VPC #2 and overwriting the remote state. Repeating for prod and dr created VPCs #3 and #4. Four VPCs, one state key, no environment discrimination. D-106 corrects this: the composition must be deterministic — same contract → same resolved stack → same state key, every time. State keys become **env-aware and stable** across apply/modify/destroy: `spike/{id}/{env}/terraform.tfstate`. The environment is part of the key, so dev/qa/prod/dr never collide. ### 2.4 Why `-reconfigure` in a fresh temp dir made it worse `terraform init -reconfigure` forces terraform to re-read the backend config and pull remote state into the local working directory. When the working directory is a fresh temp dir (as `verify_deploy_microservice.py` did), there is no local `.terraform/` state cache — terraform must pull the remote state fresh. If the remote state key is shared across environments (root cause 2) and the composition emits a new VPC each time (root cause 1), the `-reconfigure` pull merges the prior environment's state with the new resource addresses, and the subsequent `apply` creates a new VPC because the resource address in the *new* composition run differs from the one in the remote state (the L2 namespacing or the fresh temp dir caused terraform to treat the VPC as a new resource). D-101 deletes `verify_deploy_microservice.py` entirely; `run_platform.sh` gains `--apply` and `--destroy` modes that run terraform in a stable working directory (not a fresh temp dir per run), and Python never runs terraform. **Confidence: 0.90.** The state-key derivation is a direct code read (adapter.py:664,676 + contract_resolver.py:569). The 5 contracts are read verbatim. The 4-VPC mechanism is the only consistent explanation for the observed symptom (4 VPCs in the account after 4 env runs). The 0.10 residual is for the possibility that the resource-address divergence was caused by a separate composition-namespacing bug rather than the fresh temp dir alone — but either way, the two root causes (shared state key + per-contract VPC) are confirmed and D-105/D-106 correct both. --- ## FINDING 3 — Per-module terraform module design ### 3.1 What the per-module `terraform/` subdir should contain D-098/D-099: each L1 module ships a real `terraform/` module dir. The canonical layout for a multi-resource module: ``` modules/l1// interface.json # engine-agnostic (unchanged) instance.json # regression baseline (unchanged) README.md examples/ simple.yml complex.yml terraform/ # NEW — the engine binding versions.tf # required_version + required_providers variables.tf # from interface.json inputs locals.tf # default interpolation (heavy use, D-099) main.tf # resource blocks (resource shape + nested blocks) outputs.tf # from interface.json outputs ``` Trivial single-resource modules (e.g. `s3`) may inline `locals` in `main.tf` (D-099). Multi-resource modules (`vpc`, `ecs-service`, `alb`, `microservice`-shaped) get the full split. ### 3.2 The three reference modules (from interface.json) **s3** (`modules/l1/s3/interface.json`): - `variables.tf`: `bucket_name` (string, required), `region` (string, required), `kms_key_arn` (string, optional). - `locals.tf`: `sse_algorithm = "aws:kms"`, versioning default `true`, managed-key fallback (`alias/aws/s3` when `kms_key_arn` is null), the `prevent_destroy` lifecycle. - `main.tf`: `resource "aws_s3_bucket" "this" { bucket = var.bucket_name ... }` + `versioning {}` block + `server_side_encryption_configuration {}` block (CMK ref or managed fallback). - `outputs.tf`: `bucket_arn` (→ `aws_s3_bucket.this.arn`), `bucket_name` (→ `aws_s3_bucket.this.id`), `bucket_regional_domain_name` (→ `aws_s3_bucket.this.bucket_regional_domain_name`). - `versions.tf`: `terraform { required_version = ">= 1.9, < 1.10" required_providers { aws = { source = "hashicorp/aws", version = "~> 5.0" } } }`. **vpc** (`modules/l1/vpc/interface.json` — multi-resource: vpc + subnet + routetable): - `variables.tf`: `cidr` (string, required), `azs` (string, required), `name` (string, required), `region` (string, required). - `locals.tf`: `cidr_block = coalesce(var.cidr, "10.0.0.0/16")`, subnet CIDR derivation (`cidrsubnets(local.cidr_block, 8, 8, ...)` per AZ), `name` tag interpolation, the IGW + route table association. - `main.tf`: `aws_vpc`, `aws_subnet` (count/for_each over `azs` split), `aws_route_table`, `aws_internet_gateway`, `aws_route_table_association` — all the resources that the adapter's `_emit_igw()` helper synthesized dynamically now live here as real HCL. - `outputs.tf`: `vpc_id`, `subnet_ids` (join the subnet ids). - `versions.tf`: same provider block. **ecs-service** (`modules/l1/ecs-service/interface.json` — multi-resource: task_definition + service): - `variables.tf`: `image`, `port`, `cpu` (default 256), `memory` (default 512), `env` (optional), `cluster_arn`, `subnets`, `security_group`, `lb_target_group_arn` (optional), `region`, `kms_key_arn` (optional), `desired_count` (default 1), `launch_type` (default "FARGATE"), `family` (default "app"). - `locals.tf`: `container_definitions` jsonencode (image/port/env/cpu/ memory), `requires_compatibilities = ["FARGATE"]` when launch_type is FARGATE, log group name + KMS ref, the `prevent_destroy` lifecycle. - `main.tf`: `aws_ecs_task_definition` (family, container_definitions, requires_compatibilities, execution_role_arn) + `aws_ecs_service` (name, cluster, task_definition, desired_count, launch_type, network_configuration {}, load_balancer {} block). - `outputs.tf`: `service_arn`, `task_def_arn`. - `versions.tf`: same provider block. ### 3.3 How the stateless adapter assembles them The new adapter (D-098) is a ~80-line stateless assembler. It: 1. Reads `modules/registry.json` → for each resource in the resolved stack instance, looks up the L1 module by `module` field (`@`). 2. Gets the `terraform_dir` from the registry entry (or derives it as `modules/l1//terraform/`). 3. Emits a root `main.tf` with one `module "x" { source = "" ... }` block per resource, passing the resolved contract inputs as module arguments. 4. Wires refs via `module "x".` interpolations: a `ref:.` input value becomes `module..` in the consuming module block. 5. Emits the stack-level `output {}` blocks (passthrough from the producing module's outputs). 6. Emits `terraform.tf` (backend config with the env-aware state key, D-106) + `providers.tf` (aws provider, region from the first resource). The adapter holds **no** TYPE_MAP, INPUT_MAP, OUTPUT_MAP, and no type-specific branches. The engine binding (stack type → Terraform resource type, input → arg name, output → attribute name, nested blocks, defaults) lives entirely in the per-module `terraform/` subdir. `interface.json` stays engine-agnostic. **Confidence: 0.90.** The module layout is grounded in the existing `interface.json` files (read verbatim) and the Terraform module convention (versions/variables/locals/main/outputs split). The assembler design is D-098/D-099 (user-confirmed). The 0.10 residual is for the exact `terraform_dir` registry field shape (not yet implemented) and the ref-wiring syntax (`module..` vs a locals alias). --- ## FINDING 4 — Existing pipeline architecture ### 4.1 The central pipeline contract `pipelines/contract.yml` is the declarative deployment pipeline spec (a contract, not an executable workflow). It declares 9 stages: `validate-contract` → `resolve-stack` → `terraform-plan` → `checkov` → `confidence` → `apply` (dev only) → `publish-outputs` → `deploy-uptime` → `comment-outputs`. Each stage has `name`, `command`, `required` (bool), and optional `description`. The executable workflow (`.github/workflows/deploy.yml` + `.gitea/workflows/deploy.yml`, byte-identical) implements these stages by invoking `scripts/run_platform.sh`. Validated against `schemas/deploy-pipeline.schema.json`. ### 4.2 The plan-only pipelines (existing, run on every PR) Two platform pipelines run on every PR to main (offline, free): | Pipeline | File | Matrix | What it does | |----------|------|--------|--------------| | Primitives plan | `.github/workflows/primitives-plan.yml` (+ `.gitea/` byte-identical) | `s3, vpc, ecs-cluster, ecs-service, iam-role, alb, ecr, cloudfront, waf, rds` (10 primitives) | For each L1 primitive, runs `bash scripts/run_primitive_plan.sh --check-only ` — resolves the primitive's `instance.json`, runs the adapter, validates the emitted Terraform structure (offline, no AWS). | | Patterns plan | `.github/workflows/patterns-plan.yml` (+ `.gitea/` byte-identical) | `static-assets, microservice` (2 modules) | For each L2 module, runs `bash scripts/run_pattern_plan.sh --check-only ` — resolves the sample contract, runs the adapter, validates the emitted Terraform (offline). | Both trigger on `pull_request: branches: [main]`, run on `ubuntu-latest`, install `jsonschema pyyaml boto3`. The `--check-only` mode is offline (no AWS, no Checkov, no DynamoDB) — it resolves the contract/instance, runs the adapter, and validates the emitted Terraform file structure. This is what makes the pipelines free. ### 4.3 `run_platform.sh` — plan only, never apply/destroy `scripts/run_platform.sh` (521 lines) has three modes today: - `--check-only` (offline, no AWS): contract → resolver → adapter → stream TF → validate → exit 0. - `--plan-only` (requires AWS): contract → resolver → adapter → `terraform init -reconfigure -lock=false` → `terraform validate` → `terraform plan -lock=false -out=tfplan` → exit 0 (line 274–297). - default (requires AWS + Checkov + DynamoDB): contract → resolver → adapter → `terraform plan` → Checkov → confidence → outbox. **Critically, line 287 runs `terraform plan` only.** There is no `terraform apply` and no `terraform destroy` in `run_platform.sh` today. The `apply` stage in `pipelines/contract.yml` (line 54–57) declares `command: bash scripts/run_platform.sh --plan-only` — a misnomer; it runs plan, not apply. The lifecycle modes (`--apply`, `--destroy`) **must be added** (D-101). Python never runs terraform; `run_platform.sh` is the only shell entry point. ### 4.4 `run_primitive_plan.sh` `scripts/run_primitive_plan.sh` (65 lines) runs the platform pipeline for a single primitive. `--check-only` mode: resolves `instance.json`, runs the adapter, validates the emitted `{main.tf,terraform.tf,providers.tf}` exist and `main.tf` is non-empty. Default mode (requires AWS): `terraform init -backend=false` → `terraform validate` → `terraform plan`. This is the per-primitive plan check that the primitives-plan pipeline matrix invokes. ### 4.5 The byte-identical Gitea+GitHub convention `pipelines/README.md:22` documents the convention: "Create byte-identical workflow YAMLs in `.gitea/workflows/.yml` and `.github/workflows/.yml`." Both workflows must implement the same stages, commands, triggers, and runner declared in the contract. `tests/test_pipeline_contract.py` validates that the Gitea and GitHub workflow YAMLs are byte-identical and conform to the schema. The only difference is the forge runtime (Gitea Actions vs GitHub Actions). The new modules-lifecycle pipeline (D-102) must follow this convention: byte-identical `.gitea/workflows/modules-lifecycle.yml` + `.github/workflows/modules-lifecycle.yml`. **Confidence: 0.95.** All pipeline files are read verbatim from the v1.10.2 tree. The "plan only, never apply/destroy" finding is a direct read of `run_platform.sh` line 287 + the `--plan-only` exit at line 293. --- ## FINDING 5 — PERSONAS.md update for v1.11 The existing `PERSONAS.md` (v1.9) has 6 active personas: `lead-developer`, `backend-engineer`, `platform-engineer` (custom), `security-engineer` (custom), `lambda-engineer` (custom, v1.9), `frontend-engineer`. v1.11 changes the roster: - **Deactivate `lambda-engineer`** — no per-module Python this milestone (D-102: testing is pipeline-driven, not pytest). The v1.9 Lambda (`core/lambda/contract_ingestor.py`) persists but is not touched in v1.11. - **Deactivate `cost-engineer`** — not in the v1.9 roster (the v1.9 `data-engineer` is already deactivated). v1.11 has no cost-engineer work; cost is documented in `COST.md` (REQ-119) by the lead-developer. - **Keep `backend-engineer`** — owns the adapter rewrite (stateless assembler) + `core/contract_resolver.py` (env-aware state keys, D-106). - **Keep `data-engineer`** (reactivated) — owns `terraform/` (platform VPC, D-105) + the per-module `terraform/` subdirs (the engine binding, D-098/D-099/D-100). This is the heaviest territory in v1.11: 12 L1 modules each get a real `terraform/` module dir. - **Keep `general`** (the `lead-developer` + `backend-engineer` pipeline work) — owns `pipelines/` + `.gitea/workflows/` + `.github/workflows/` (the modules-lifecycle pipeline, D-102) + `scripts/run_platform.sh` (`--apply`/`--destroy` modes, D-101). ### Territory alignment (v1.11) | Persona | Territory | Domain | |---------|-----------|--------| | backend-engineer | `adapters/terraform/adapter.py` (rewrite to stateless assembler), `core/contract_resolver.py` (env-aware state keys), `schemas/stack.schema.json` (if touched) | backend | | data-engineer | `terraform/` (platform VPC, D-105), `modules/l1/*/terraform/` (per-module terraform subdirs — the engine binding), `modules/l1/*/interface.json` (defaults move from adapter to interface), `modules/registry.json` (terraform_dir field) | data | | general (lead-developer + backend-engineer) | `pipelines/modules-lifecycle.yml`, `.gitea/workflows/modules-lifecycle.yml` + `.github/workflows/modules-lifecycle.yml` (byte-identical), `scripts/run_platform.sh` (`--apply`/`--destroy`), `scripts/run_primitive_plan.sh` (if extended), `modules/STANDARDS.md` §8 rewrite | coordination + pipelines | ### Territory enforcement: `warn` Co-authoring is expected on the adapter + `run_platform.sh` boundary (backend-engineer rewrites the adapter; general adds the lifecycle modes to `run_platform.sh` that invoke it). `warn` keeps it frictionless — cross-territory edits are logged in the commit message but do not fail the task. ### Domain priority (v1.11) `data → backend → general` Rationale: the terraform foundation (per-module `terraform/` subdirs + platform VPC) is the binding constraint — the stateless adapter cannot be written until the reference s3 module exists (D-107: P56a proves the design with s3 first). Backend (adapter/resolver) follows once the module shape is proven. General (pipelines/workflows) wires the lifecycle modes last, once the adapter + modules produce valid terraform. The updated `PERSONAS.md` is written to `/root/acdl/.ciagent/PERSONAS.md` (see that file). YAML frontmatter with `active`, `phase_specific`, and `reason` fields per persona. **Confidence: 0.90.** The persona changes are grounded in the CLARIFY decisions (D-098..D-107) and the v1.11 scope (no per-module Python → lambda-engineer deactivated; terraform module authoring is the heaviest work → data-engineer reactivated). --- ## Assumptions logged | ID | Assumption | Confidence | Rationale | |----|------------|------------|-----------| | A-1.1 | The `terraform_dir` field will be added to `modules/registry.json` entries (or derived as `modules/l1//terraform/`) so the stateless adapter can locate each module's terraform subdir. | 0.85 | D-098 says the adapter reads `registry.json` → gets `terraform_dir`. The exact field name is not yet locked; the derivation path is the obvious fallback. | | A-1.2 | The ref-wiring syntax in the root `main.tf` will be `module..` (standard Terraform module output interpolation), not a locals alias. | 0.85 | The existing `_ref_expr` already produces `..`; the module equivalent is `module..`. Standard Terraform convention. | | A-2.1 | The 4-VPC bug's resource-address divergence was caused by the fresh temp dir + `-reconfigure` pull merging remote state with new composition runs, not a separate composition-namespacing bug. | 0.80 | The two confirmed root causes (shared state key + per-contract VPC) are sufficient to explain 4 VPCs. The exact terraform-state mechanics of the divergence are inferred, not observed in a debug log. | | A-3.1 | Trivial single-resource modules (s3) may inline `locals` in `main.tf`; multi-resource modules (vpc, ecs-service, alb) get the full 5-file split. | 0.90 | D-099 states this explicitly. | | A-4.1 | The modules-lifecycle pipeline will matrix-run each L1 module's `examples/{simple,complex}.yml` contracts (the modify variants), not new contract files. | 0.90 | D-103: "Uses the module's own existing example contracts as the modify variants. No extra contract files needed." | | A-5.1 | `platform-engineer` and `security-engineer` from the v1.9 roster are folded into `data-engineer` and `backend-engineer` for v1.11 (the v1.11 scope is terraform + adapter + pipelines, not security adapters or HITL gates). | 0.75 | The v1.11 scope (D-097..D-107) does not touch Wiz/Kyverno/Checkov/HITL. The persona roster is simplified to the three active domains. | --- ## Decisions surfaced (research → already bound in CLARIFY) All v1.11 binding decisions (D-097..D-107) were committed in the CLARIFY stage (`80b7286`) before this research ran. This research *grounds* those decisions with codebase evidence; it does not surface new binding decisions. The decisions are summarized in §Background above and documented in full in the CLARIFY commit. --- # v1.12 Addendum — Presentation Refinement Research > Generated: 2026-07-29. Phase 66. Milestone v1.12. > Mode: docs-only NFR milestone focused on the leadership decks. > Surface: `docs/presentations/` (PW + DX, all four layers) + one real > adapter fix + two probe fixes required to make deck claims true. ## Background — why v1.12 exists v1.11 (P56a–P65) landed the stateless adapter, pipeline-driven lifecycle testing, single platform VPC, `COST.md`, `PRE_MORTEM.md`, and a teardown to zero-cost. P65's plan (REQ-118) required the decks to be rewritten to "Verified live-aws via lifecycle pipeline; torn down to zero-cost." That rewrite did not fully land on the deck artifacts. This research is a drift audit: a systematic comparison of the deck artifacts against the v1.11-verified reality. ## FINDING 1 — Drift audit (9 items) Systematic comparison of `docs/presentations/*` against `.ciagent/CAPABILITY_INVENTORY.md`, `.ciagent/COST.md`, `.ciagent/PRE_MORTEM.md`, `.ciagent/ROADMAP.md`, and `git log`. 1. **Wrong verification status.** Both rendered HTML decks still say "6 cloud capabilities are design-verified + locally emulated, deploy-unverified (IAM drift)" (PW "Testing vs. Planned" slide; DX slide A6). `CAPABILITY_INVENTORY.md` says 22/22 Verified and the IAM-drift framing was *removed* in P65. The decks contradict the inventory. Verified: `grep -c "deploy-unverified\|IAM drift\|design-verified" docs/presentations/*.html` → 3 hits per deck. 2. **Re-verification header stale.** Both source `.md` headers say "Re-verification (2026-07-27)… v1.10 Phase 54… 16/16… 6 IAM-gated escalated." Should reflect v1.11: 22/22 Verified, torn down. 3. **Road to the North Star diagram stale.** `docs/presentations/assets/mmd/road-to-north-star.mmd` shows v1.10 as "NEXT" with "HITL wiring / all-runner OIDC / regulatory ledger". v1.11 is complete; the diagram must advance. 4. **Rendered HTML not re-rendered.** `git log` shows the HTML was last touched at `10b87a6` (P57), *before* v1.11. P65's "re-render HTML" task did not reach the rendered artifacts. 5. **Version refs stale.** Decks reference `@v1.10` in deploy.yml `uses:` snippets (Safe Promotion Path, Safe Decommission). Ship tag is now `v1.11.0`; will be `v1.12.0` at Phase 70 complete. 6. **Cost story has no real numbers.** `COST.md` exists ($0.001883 over 8 days, ~$0.007/mo, S3-dominated, zero BAU compute) but the decks' A6 "Operating Model & Cost" slide is generic prose with no figures. 7. **Pre-mortem unreferenced.** P65 planned to add a pre-mortem reference; `PRE_MORTEM.md` exists (v1.10 decay root cause + four forward failure modes) but no deck slide references it. 8. **Two v1.11 stories absent.** (a) Architectural simplicity: adapter 918→~80 lines, defaults centralized in per-module `terraform/` dirs. (b) Verifiable deploys: a `modules-lifecycle` pipeline matrix-runs each module apply→modify→destroy against live AWS. Neither is in the decks. 9. **Duplicated story-beat lines.** `how-the-platform-works.md` slides 3–10 each repeat their intro line twice (a copy-paste artifact). ## FINDING 2 — Regression gate surfaces real decay (D-091) The v1.12 regression gate run (Phase 66) re-ran the D-091 regression gate to back every deck claim. It found **3 Broken capabilities**: `{'Verified': 19, 'Decayed': 0, 'Broken': 3}`. ### CAP-013 — live-aws — REAL platform defect (Class A) `adapters/terraform/adapter.py:159-172` (the `seen` dedup loop) collapses the two `ecs-service` sub-resources (`service-task-definition` + `service-service`, both module `ecs-service@1.0.0`) into ONE `module "service-task-definition"` block. But the stack output `service_arn` (resolver `from: "service-service"`) is emitted as `value = module.service-service.service_arn` — referencing a module call that was never emitted. `terraform validate` fails: "No module call name." The same defect silently breaks the `alb` L1 too. Static- assets (CAP-014) doesn't hit it because its L1s are single-resource. **Classification A — real platform defect.** The adapter produces invalid Terraform for any multi-resource L1 with stack-level outputs. **Fix required before decks can claim 22/22 Verified.** ### CAP-017 — lifecycle-pipeline — regression-probe bug (Class B/C) `core/regression_verify.py:444` hardcodes `required = ["versions.tf", "variables.tf", "locals.tf", "main.tf", "outputs.tf"]`. The CAP-017 probe targets the `rds` L1 module, whose `main.tf` uses only `var.*` and `aws_db_subnet_group.this` — no `local.*` references, so `locals.tf` is legitimately absent. The probe is over- strict. The rds module is correctly structured; the capability works. **Classification B/C — trivial probe fix.** Drop `locals.tf` from the required list, or make it conditional on `local.` usage. ### CAP-018 — lifecycle-pipeline — regression-probe bug (Class B/C) `core/local_emulators.py:273` defines `LocalLambdaStub` as a dataclass with one required field `outbox: FlatFileOutbox`. Every real caller passes it (`core/local_emulators.py:464`, the tests). The CAP-018 probe at `core/regression_verify.py:486-491` is the *only* caller that instantiates it bare: `LocalLambdaStub()` → `TypeError`. The probe was added in P63 and never aligned with the real signature. The capability is exercised green by CAP-011. **Classification B/C — trivial probe fix.** Pass an `outbox` to the constructor. ### Implication for the decks `CAPABILITY_INVENTORY.md` claims 22/22 Verified, but the regression gate (D-091 — the exact mechanism PRE_MORTEM.md FM-3 says backs every deck claim) shows CAP-013 is genuinely broken. **The inventory overstates.** v1.12 cannot ship decks claiming 22/22 until CAP-013 is fixed and the gate re-runs clean. This is the structural mitigation the pre-mortem requires (verified-only claims; decks unfrozen only after re-verification). The user decision: fix the defect inside v1.12 (Phase 67), then the decks can honestly claim 22/22. ## FINDING 3 — Talking points structure gap Both talking-points files have only 5 appendix sections (A1–A5) while the Marp decks have 6 (A6 = "Operating Model & Cost"). The A6 content exists in the Marp deck and source markdown but was never distilled into the talking points. The re-distill step (Phase 69) must add the A6 section to both talking-points files. ## FINDING 4 — Versioning facts - Current ship tag: `v1.11.0` (v1.11 complete). - `deploy.yml` still references `v1.9` in comments + `ref: v1.9` — v1.11 apparently did not bump the deploy workflow `uses:` tag (the bump is a separate concern; decks use the current ship tag). - Decks should show `@v1.11` in examples (current state); Phase 70 bumps to `@v1.12` after the tag exists. ## Assumptions logged - No automated `ci-doc-verifier` script exists in the repo. The plan's "ci-doc-verifier confirms" is satisfied by a manual grep-based verification recorded in the Phase 70 VERIFY step (consistent with how prior NFR-patch phases handled it). Confidence 0.90 — verified by `ls scripts/ | grep doc` and `grep -rl deck tests/`. - PPTX export requires Chromium + Marp CLI; the environment has it (`/root/.cache/ms-playwright/chromium-1217/chrome-linux64/chrome`). PPTX is uploaded to the Gitea release, not committed. Confidence 0.85 — README documents the path; the chromium binary exists. ## Decisions surfaced (research → bound in CLARIFY-equivalent) - **D-108** — v1.12 includes one real adapter fix (CAP-013) and two probe fixes (CAP-017, CAP-018) as Phase 67 prerequisites, so the decks can honestly claim 22/22 Verified. The milestone is "presentation refinement" but the verified-only-claims pre-mortem mitigation makes the fixes mandatory. The user confirmed this scope (interactive decision, 2026-07-29). - **D-109** — Decks use `@v1.11` in examples during Phase 68 (current state), bumped to `@v1.12` at Phase 70 complete after the tag exists. Avoids a dangling reference to a tag that doesn't exist yet. --- ## v1.14 Research Addendum — NFR Refinement scope audit (2026-07-29) > Phase 0 RESEARCH for milestone v1.14 (NFR Refinement). A full codebase > survey (8 categories, file:line evidence) was conducted to populate the > 20-phase scope. This addendum records the findings; the phase list is > in ROADMAP.md §v1.14; the requirements are in REQUIREMENTS.md §v1.14. ### Survey method Read-only survey of `/root/acdl` at v1.13.2 (HEAD `139224ff`, 533 tests collected). 8 categories: stubs, P1/P2 backlog, security, docs drift, test gaps, terraform gaps, workflow gaps, config hygiene. All file:line references verified against the live codebase. ### Finding 1 — Open P1/P2 backlog (REVIEW.md v1.11) 5 P1 + 4 P2 findings from the v1.11 multi-persona review remain open: | ID | File:Line | Status | v1.14 phase | |----|-----------|--------|-------------| | P1-1 | `adapter.py:159-170` (silent drop of unregistered-module resources) | open | P1 | | P1-2 | `static-assets/composition.json` (unwired cloudfront inputs; WAF unconditional) | open | P2 | | P1-3 | `run_l2_lifecycle_*.sh` (vestigial `[ci-vpc-outputs.json]` arg) | open | P3 | | P1-4 | `CAPABILITY_INVENTORY.md:9-16` (summary table stale) | **fixed** (now 22/22) | — | | P1-5 | `regression_verify.py:432-519` (CAP-017..022 offline proxy, no `terraform validate`) | open | P4 | | P2-1 | `alb/main.tf:9` (`name_prefix="tg-ci-"` discards `var.name`) | open | P6 | | P2-2 | `test_adapter.py` (no dedup-merge or remote-state-key test) | open | P5 | | P2-3 | `waf/complex.yml` + `locals.tf` (redundant `upper()` + uppercase example) | open (post-hoc) | folded into P2 | | P2-4 | `COST.md:106` (account ID published; accepted exposure) | open (post-hoc) | folded into P8 (centralize code-side) | ### Finding 2 — Security posture gaps **Swallowed errors (6 sites):** - `core/local_emulators.py:374` — `except Exception: pass` in `_fake_urlopen`; if patching fails, urlopen stays real → network egress. [SEC] → P7. - `core/lambda/contract_ingestor.py:157` — GitHub search failure → `existing = []` → duplicate issues. → P7. - `terraform/bootstrap/create_state_backend.py:51` — over-broad `except Exception:` on `head_bucket` → spurious `create_bucket` on permissions/network errors. → P7. - `core/output_publisher.py:100,168` — SSM/GitHub failure → silent `None`/`False`. → P7. - `terraform/bootstrap/apply_iam_baseline.py:78` — over-broad on old-version delete. → P7. **Hardcoded account ID `581513795199` (15+ sites):** `adapter.py:125,140`, `apply_iam_baseline.py:33`, `create_state_backend.py:33,35`, `push_consumer_image.py:32`, terraform state-bucket names, ECR image ref. → P8 (externalize to `ACDL_AWS_ACCOUNT_ID` / `data.aws_caller_identity`). **IAM policy wildcards (6 `Resource: "*"` statements):** `spike_runner_policy.json` — cloudfront (line 117), wafv2 (129), kms (218), iam (236). KMS allows key creation/deletion on ANY key; IAM allows role creation on ANY role. → P9 (scope to `acdl-*` ARNs). **Contract-ingestor identity validation gap:** `contract_ingestor.py:221-245` — `_validate_caller_identity` validates `consumerRepo` format only; doesn't verify caller owns the repo (ABAC reliance). No `contractId`/`environment`/`error` validation. → P10. **Schema validation gaps:** `contract.schema.json` + `environment.schema.json` — no `additionalProperties: false` (undocumented fields pass silently); no format validation for bucket/ARN/CIDR. → P11. **Credential hygiene:** `.gitignore` covers `.env*`/`*.tfstate*` but no credential-pattern catch-all (`*.pem`/`*.key`/`*.p12`). → P12. **Audit ledger integrity (D-083):** `audit_ledger_design.md:47-70` — JWS + Object Lock + DLQ deferred. Per D-096, stays deferred; documented in P19. The hash-chain + DynamoDB outbox is the v1.14 audit record. ### Finding 3 — Stubs / missing functionality - `adapters/kyverno/kyverno_adapter.py:11,115-116` — `--kube-version` parsed then discarded (`_ = kube_version`). → P13 (implement or remove + document). - `scripts/__pycache__/verify_deploy_microservice.cpython-312.pyc` — orphan bytecode for a deleted source file. → P14. - `core/regression_verify.py:237` — DynamoDB write deferred to Phase 54 (outbox hash-chain verified, no real DynamoDB write). Accepted deferral. - `adapters/wiz/wiz_adapter.py` — real GraphQL client (not a stub); degrades gracefully. OK. - `core/separation_of_duties.py` — `route_halt_artifact` is real (SNS + outbox fallback). OK. - `core/lambda/contract_ingestor.py` — `report_error` is real (GitHub issues via Secrets Manager). OK. ### Finding 4 — Documentation drift - `ARCHITECTURE.md` — no v1.11/v1.12/v1.13/v1.14 addendum; line 500-506 still describes the **old** parameterized adapter (pre-stateless rewrite). → P19. - Stale `@v1.6`–`@v1.9` workflow refs in `README.md:225`, `docs/consumer-guide.md` (12 sites), `docs/architecture.md:233`, `docs/pipeline/versioning.md:29`, `docs/pipeline/index.md:42`. → P19. - `modules/STANDARDS.md` §8 references `TYPE_MAP` (deleted in v1.11); §9.4 requires 5-file split but §489-492 allows inlining — inconsistent. → P18. - `COST.md` window stops at v1.10; no v1.11–v1.13 spend. → P19. - `GRILL.md` G-005/G-008 escalations — CAP-017..022 now Verified via lifecycle pipeline; COST.md now exists. → P19 (mark resolved). - `IAM_POLICY.md` — reflects v1.11 re-bootstrap but not v1.12/v1.13. → P19. - Decks reference "v1.12" verification status; not re-synced for v1.13.2. → P19. ### Finding 5 — Test coverage gaps - 533 tests collected; 5 `@pytest.mark.slow` (deselected from fast suite). 7 scripts with no test: `seed_uptime_monitors.py`, `push_consumer_image.py`, `sync_to_gl.sh`, `post_stage_comment.sh`, `rotate_spike_key.sh`, `create_state_backend.py`, `create_iam_user.py`. → P15. - Adapter dedup-merge + `ACDL_REMOTE_STATE_KEY` override — no unit test (P2-2). → P5. ### Finding 6 — Terraform gaps - 3 L1 modules lack `locals.tf` (`ecr`, `ecs-cluster`, `rds`). → P18. - `static-assets/composition.json` unwired inputs (P1-2). → P2. - `terraform/platform/main.tf:255` — hardcoded CIDR; `count=2` subnets not data-driven. → P20. - `terraform/bootstrap/create_state_backend.py:51` — over-broad except (Finding 2). → P7. ### Finding 7 — Workflow / pipeline gaps - 4 GitHub-only workflows (patterns-plan, platform-test, primitives-plan, release) — no Gitea mirror. → P16. - `rotate_spike_key.sh` (only `set -u`), `sync_to_gl.sh` (no `set` flags). → P16. - 3 shared workflows (ci, deploy, modules-lifecycle) byte-identical (verified). OK. - modules-lifecycle matrix covers all 12 L1 + 2 L2. OK. ### Finding 8 — Config / project hygiene - `config.json` bash_allowlist has dead JS entries (npm/node/jest/eslint /tsc — no package.json). → P14/P17. - `config.json` `branching_strategy: "phase"` mismatched with flat-workflow practice. → P17. - `config.json` `ollama-cloud.base_url: ""` (empty; no `glm` model configured). → P17. - `config.json` `frontend-engineer` persona still in `personas[]` (PERSONAS.md:80 says inactive). → P17. - `pyproject.toml` version `1.3.0` (stale); coverage source `acdl_platform` (renamed to `core` in v1.6). → P14. ### Persona assessment (v1.14) The v1.14 milestone is NFR-only (bug fixes, security, tests, docs). The active persona roster from v1.11 (PERSONAS.md) carries forward unchanged: - **lead-developer** (active) — coordination; owns the wave ordering + cross-phase dependencies. - **backend-engineer** (active) — owns `adapters/`, `core/` (adapter dedup, contract ingestor, regression gate, output publisher). - **data-engineer** (active) — owns `terraform/`, `modules/` (ALB fix, static-assets wiring, platform VPC, IAM policy, STANDARDS). - **frontend-engineer** (inactive) — no frontend; decks are markdown (lead-developer territory). Stays deactivated per PERSONAS.md:80. No custom personas needed for v1.14 (no new domains). Territory enforcement = `warn` (config.json:167). The v1.14 work is concentrated in `adapters/`, `core/`, `terraform/`, `scripts/`, `tests/`, `docs/`, `.ciagent/` — all within existing persona territories.
