acdl	v1.11	2026-07-28	lead-developer	v1.9 PERSONAS.md (lambda-engineer reactivated for v1.11; new cost-engineer persona added for the AWS spend tier)	typecheck test build note terraform validate && python3 -m py_compile core/**/*.py && python3 -m jsonschema schemas/*.schema.json scripts/verify_phaseNN.sh terraform init 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, v1.9)

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-engine-agnostic, adapter-is-only-engine-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 engine-agnostic; the adapter is the only engine-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, v1.9, reactivated v1.11)

• Domain: serverless
• Active: true
• Phase-specific: true (reactivated for v1.11 Phases 56/57/58; removed after milestone COMPLETE)
• Frameworks: python, aws-lambda, boto3, dynamodb, aws-secretsmanager, aws-sns, 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, sns-topic-arn-from-env
• Territory: core/lambda/** (contract_ingestor.py + handler), terraform/platform/main.tf (Lambda + Function URL + DynamoDB + KMS + Secrets Manager + IAM + acdl-change-requests table + acdl-sod-halt SNS topic), terraform/platform/consumer_invoke_policy.json, terraform/platform/variables.tf
• Reason: Reactivated for v1.11 Phase 57 — CAP-018 (Lambda contract-ingestor deployed + invocable) needs the lambda-engineer to verify the live Lambda Function URL responds to an ingest request with a real record written to acdl-contracts. The persona is removed from the roster after v1.11 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.

cost-engineer (custom, v1.11)

• Domain: finops
• Active: true
• Phase-specific: true (created for v1.11 Phase 59; removed after milestone COMPLETE)
• Frameworks: aws-cost-explorer, aws-billing, boto3-ce, markdown
• Constraints: document-real-spend-not-estimates, cost-avoidance-via-local-emulators-primary-tier, teardown-is-mandatory-pre-complete (D-096), no-permanent-live-spend-beyond-milestone-window, per-service-breakdown-not-lump-sum
• Territory: .ciagent/COST.md (new), scripts/query_aws_spend.py (new, Phase 59), .ciagent/REGRESSION_REPORT.md (cost-section addendum only)
• Reason: Created for v1.11 Phase 59 (REQ-119, G-008 escalation). Owns the Cost Explorer query + the COST.md document + the teardown-cost-ceiling guidance for downstream clones. Distinct from platform-engineer (which owns infra-as-code but not the spend accounting) and from lead-developer (which owns .ciagent/ metadata but the cost doc is a finops deliverable, not pure metadata). Removed after milestone COMPLETE; COST.md persists but the persona is inactive going forward.

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 (engine-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 → cost → frontend

Rationale: in v1.11, the binding constraints are the IAM re-bootstrap (security owns least-privilege policy scope), the live terraform apply (platform owns the stacks), the Lambda ingest verification (lambda owns the live probe), the cost documentation (cost owns the spend query + COST.md), and the deck rewrite (lead-developer owns .ciagent/ + the deck edits). frontend is unchanged from v1.0 (evidence timeline, idle this milestone).

Conflict resolutions (lead-developer arbitration)

• backend-engineer vs platform-engineer over schemas/ir.schema.json + schemas/stack.schema.json: platform-engineer owns the IR (engine-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 (engine 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. v1.11's IAM + deploy + teardown scope means co-authoring across territories is likely (e.g. security + platform on spike_runner_policy.json; lambda + platform on terraform/platform/main.tf); warn keeps it frictionless.
