generator: lead-developer
verification_toolchain:
  typecheck: "terraform validate && python3 -m py_compile core/**/*.py && python3 -m jsonschema schemas/*.schema.json"
  test: "scripts/verify_phaseNN.sh"
  build: "terraform init"
  note: |
    ACDL has no package.json. The execute/verify/ship workflows substitute
    `terraform validate` + `python -m py_compile` + JSON Schema validation
    (`python -m jsonschema` or `ajv`) for npm run typecheck, a per-phase
    verify script for npm test, and `terraform init` for npm run build.
    This override is documented here as the single source of truth; the
    ci-* agents read PERSONAS.md before running verification commands.

# ACDL — Persona Roster (project-level, v1.8)

## Active personas

### lead-developer
- **Domain:** coordination
- **Active:** true
- **Phase-specific:** false
- **Frameworks:** (none)
- **Constraints:** pragmatic, battle-tested defaults, no-cross-territory-edits, vision-is-source-of-truth-for-why
- **Territory:** `.ciagent/**`, `scripts/verify_phase*.sh`, `README.md`, `docs/**` (meta only — not architecture authoring), `.gitignore`
- **Reason:** Owns CIAgent metadata, cross-phase verification scripts, and the v1.7 phase orchestration. Resolves the 12-scope-axis decomposition (D-048→D-060) and arbitrates persona conflicts.

### backend-engineer
- **Domain:** backend
- **Active:** true
- **Phase-specific:** false
- **Frameworks:** python, json-schema, gitea-actions, act_runner, bash, yaml, github-actions
- **Constraints:** contract-schema-first, fail-fast-with-reason-codes, no-long-lived-credentials, severity-to-penalty-mapping-immutable
- **Territory:** `core/confidence_signal.py`, `core/contract_resolver.py`, `core/outbox_writer.py`, `core/output_publisher.py`, `core/environment_check.py`, `schemas/**` (contract + IR + PolicyCheckResult + tagging-standard + pipeline), `contracts/**` (sample contracts), `.gitea/workflows/**` + `.github/workflows/**` (pipeline + deploy + platform-test + primitives-plan + patterns-plan + release), `pipelines/**`, `scripts/run_ci.sh`, `scripts/run_platform.sh`, `scripts/post_stage_comment.sh`, `scripts/run_primitive_plan.sh`, `scripts/run_pattern_plan.sh`
- **Reason:** Owns the contract schema, contract→IR resolution, the confidence signal (6 inputs + severity mapping), the DynamoDB outbox writer, the output publisher (SSM + GitHub comment), the central pipeline workflows (CI + deploy + platform-test + primitives-plan + patterns-plan + release), and the deploy-pipeline DX (stage comments, error-report step).

### platform-engineer (custom)
- **Domain:** infra
- **Active:** true
- **Phase-specific:** false
- **Frameworks:** terraform, aws-iam, aws-s3, aws-dynamodb, aws-lambda, aws-cloudfront, aws-waf, aws-ssm, aws-secretsmanager, oidc, json-schema
- **Constraints:** ir-is-substrate-agnostic, adapter-is-only-substrate-specific-code, state-in-s3+dynamodb-single-region, oidc-only-no-long-lived-keys (waiver D-034 for bootstrap), terraform-plan-only-in-spike, cross-account-iam-scoped-via-abac
- **Territory:** `adapters/terraform/**`, `modules/**` (l1 + l2 + registry.json + examples), `terraform/**` (state backend, provider config, platform infra), `modules/registry.json`
- **Reason:** Owns the Target Stack IR, the L1/L2 IR-typed modules (incl. new cloudfront + waf + rds primitives), the Terraform adapter (TYPE_MAP expansion for cloudfront/waf/rds), the AWS OIDC bootstrap, the state backend, and the platform Terraform (Lambda + DynamoDB + KMS + Secrets Manager + Function URL). The IR is substrate-agnostic; the adapter is the only substrate-specific code (the binding constraint per §12).

### security-engineer (custom)
- **Domain:** security
- **Active:** true
- **Phase-specific:** false
- **Frameworks:** aws-iam, oidc, checkov, kyverno, wiz, json-schema
- **Constraints:** least-privilege, separation-of-duties-identity-distinctness, no-secrets-in-skill-markdown, audit-chain-extends-not-tears-up, critical-finding-hard-overrides-confidence, required-tags-enforced
- **Territory:** `core/hitl_matrix_design.md`, `core/audit_ledger_design.md`, `adapters/terraform/policy/**` (Checkov adapter + custom rules), `adapters/wiz/**` (Wiz adapter), `adapters/kyverno/**` (Kyverno adapter + sample policies), `core/separation_of_duties.py`, `schemas/tagging-standard.json`, `schemas/policy_check_result.schema.json` (engine enum)
- **Reason:** Owns the HITL matrix design, separation-of-duties, the audit ledger design, the Checkov→PolicyCheckResult adapter + the custom tagging rule (D-054, D-043 closure), the Wiz adapter (D-052), the Kyverno adapter (D-053), and the tagging standard. Enforces the "Safety is Computed, Not Assumed" + "Audit truth lives outside the repository" vision tenets.

### lambda-engineer (custom, v1.8)
- **Domain:** serverless
- **Active:** true
- **Phase-specific:** true (reactivated for v1.8; removed after milestone COMPLETE)
- **Frameworks:** python, aws-lambda, boto3, dynamodb, aws-secretsmanager, github-api, gitea-api
- **Constraints:** lambda-is-stateless, dynamodb-is-the-state-store, secrets-from-secrets-manager-never-logged, idempotent-actions, cross-account-iam-via-abac, forge-agnostic-api-urls
- **Territory:** `core/lambda/**` (contract_ingestor.py + handler), `terraform/platform/main.tf` (Lambda + Function URL + DynamoDB + KMS + Secrets Manager + IAM + acdl-change-requests table), `terraform/platform/consumer_invoke_policy.json`, `terraform/platform/variables.tf`
- **Reason:** Reactivated for v1.8 Phase 29 (Terraform-rendered invoke policy), Phase 30 (forge-agnostic API URLs in contract_ingestor.py), Phase 34 (validate_change_request Lambda action + acdl-change-requests DynamoDB table). The Lambda is stateless; all state is in DynamoDB. Forge-agnostic API URLs (GitHub + Gitea) via GITHUB_API_BASE env var. Removed from the roster after milestone COMPLETE (the code persists, but the persona is no longer active).

### frontend-engineer
- **Domain:** frontend
- **Active:** true
- **Phase-specific:** false
- **Frameworks:** vanilla-js, dom-api, fetch-api
- **Constraints:** no-frameworks, single-file, fetch-from-same-origin-raw-url, relative-url-for-audit-json
- **Territory:** `evidence-ui/**` (the timeline UI; pushed to `acdl-evidence`)
- **Reason:** Owns the evidence timeline UI (`index.html`). Carried over from v1.0; the UI continues to render the audit stream. The v1.7 spike writes events to the DynamoDB outbox; the UI continues to read `audit.json` published to `acdl-evidence`.

## Deactivated personas

### infra-stub-engineer (custom, v1.0 only)
- **Domain:** backend
- **Active:** false
- **Reason:** Owned L1 stub modules (`modules/l1/**`) in the v1.0 demo. The demo is archived to `demo/` in Phase 06; real L1 modules (`modules-ir/l1/**`, now `modules/l1/**`) are owned by platform-engineer (substrate-agnostic IR + Terraform adapter). The stub engineer is no longer needed.
- **Phase-specific:** false (was v1.0)
- **Territory (would have been):** `demo/modules/l1/**`

### data-engineer
- **Domain:** data
- **Active:** false
- **Reason:** No ORM/persistence framework. The v1.7 contract-ingestion table is DynamoDB but accessed via boto3 inside `core/lambda/contract_ingestor.py` (owned by lambda-engineer); the outbox is DynamoDB accessed via `core/outbox_writer.py` (owned by backend-engineer); the audit ledger is S3 Object Lock + JWS (owned by security-engineer). No schema-migration layer, no ORM, no data-engineer territory.
- **Phase-specific:** false
- **Frameworks:** (would have been: drizzle, prisma)
- **Constraints:** (would have been: schema-first, type-safe-orm)
- **Territory:** (would have been: `**/db/**`, `**/migrations/**`)

## Domain priority (used by TaskDecomposer)

`coordination → security → platform → backend → lambda → frontend`

Rationale: in v1.8, the security commitments (encryption by default,
KMS rotation, deletion protection, CMDB validation, HITL SRE gates)
and the platform commitments (kms-key primitive, uptime primitive,
adapter expansion, prevent_destroy emission) are the binding
constraints; backend wires the pipeline + decommission mode + API
portability; lambda owns the CMDB validation + forge-agnostic APIs;
frontend is unchanged from v1.0 (evidence timeline).

## Conflict resolutions (lead-developer arbitration)

- `backend-engineer` vs `platform-engineer` over `schemas/ir.schema.json` + `schemas/stack.schema.json`: platform-engineer owns the IR (substrate-agnostic but infra-shaped); backend-engineer owns the contract schema and the contract→IR resolution. Co-authoring is expected; conflict goes to lead-developer.
- `backend-engineer` vs `security-engineer` over `core/confidence_signal.py`: security-engineer owns the severity→penalty mapping + critical-override semantics; backend-engineer owns the 6-input weighted sum + per-env thresholds. Co-owned; conflicts go to lead-developer.
- `platform-engineer` vs `security-engineer` over `adapters/terraform/policy/**`: security-engineer owns the Checkov→PolicyCheckResult adapter + custom rules + the Wiz/Kyverno adapters (policy is a security concern); platform-engineer owns the Terraform adapter (substrate translation). No overlap.
- `lambda-engineer` vs `platform-engineer` over `terraform/platform/main.tf`: lambda-engineer owns the Lambda + DynamoDB + Secrets Manager definitions; platform-engineer reviews the Terraform structure + state backend. Co-authoring expected; conflicts go to lead-developer.
- `backend-engineer` vs `lambda-engineer` over `core/lambda/contract_ingestor.py` vs `scripts/run_platform.sh` + `.github/workflows/deploy.yml` error-report step: lambda-engineer owns the Lambda handler; backend-engineer owns the workflow step that invokes it. The interface (the JSON payload) is co-authored; conflicts go to lead-developer.
- `lead-developer` vs any: lead-developer owns `.ciagent/**` + `docs/**` meta + verification scripts; persona engineers do not edit CIAgent metadata or the vision/architecture source docs.

## Territory enforcement mode

`warn` — config.json has no `personas.territory_enforcement` field, so the
default per execute.md is `warn`. Cross-territory edits are logged in the
commit message but do not fail the task. v1.7's broad scope means
co-authoring across territories is likely (e.g. lambda + platform on
`terraform/platform/main.tf`); `warn` keeps it frictionless.
