  note: |
    v1.25 is the kyverno-json Unified Policy Engine milestone — a feat
    milestone. Four active personas: lead-developer (coordination +
    docs + ARCHITECTURE.md §12.7), backend-engineer (core/policy_engine.py
    protocol + registry + contract_resolver.py wiring + run_platform.sh
    Step 5 + pipeline tests), policy-engineer (adapters/kyverno-json/
    engine + policies across all 4 target dirs + meta-policies + policy
    tests + adapter README + STANDARDS.md policy-authoring section),
    data-engineer (config.json policy object + schemas/README.md note +
    capability-inventory JSON fixture for regression policies).
    frontend-engineer stays deactivated (no UI). The policy-engineer is a
    new custom persona created for this milestone's policy domain (see
    RESEARCH.md §4 — kyverno-json + JMESPath is a distinct framework from
    backend-engineer's fastify/hono).

# ACDL — Persona Roster (v1.25 kyverno-json Unified Policy Engine)

> v1.25 roster. Four active personas + one deactivated. This is a feat
> milestone: the work is a swappable policy-engine protocol + a new
> adapter + policies across 4 Nova artifacts + pipeline wiring + docs.
> The policy-engineer is a new custom persona — kyverno-json + JMESPath
> is a specialized domain that doesn't fit backend-engineer's
> fastify/hono frameworks or data-engineer's drizzle/postgresql.

## Active personas

### lead-developer
- **Domain:** coordination + docs
- **Frameworks:** []
- **Constraints:** ["pragmatic", "battle-tested defaults", "docs match code", "swap boundary is the moat"]
- **Territory:**
  - `.ciagent/ARCHITECTURE.md` (§12.7 Policy Engine Registry — NEW)
  - `.ciagent/PROJECT.md` (v1.25 section)
  - `.ciagent/REQUIREMENTS.md` (v1.25 section)
  - `.ciagent/ROADMAP.md` (v1.25 section)
  - `.ciagent/PLAN.md`, `.ciagent/RESEARCH.md`, `.ciagent/CLARIFY.md`,
    `.ciagent/GRILL.md`, `.ciagent/PERSONAS.md`
  - `docs/METRICS.md` (swappable engine narrative — REQ-307)
- **Reason:** Owns the milestone coordination + the architecture
  narrative. The swap boundary (PolicyEngine protocol) is the moat per
  Strategic Objective #2 — the lead-developer owns the boundary
  description in ARCHITECTURE.md §12.7 and the docs/METRICS.md note.
  No Python policy code (backend-engineer + policy-engineer territory).
  No UI (frontend-engineer deactivated).

### backend-engineer
- **Domain:** backend (Python + bash + pipeline wiring)
- **Frameworks:** ["boto3", "terraform"]
- **Constraints:** ["api-first", "strict-typing", "engine-agnostic confidence signal", "fail-soft when kj absent"]
- **Territory:**
  - `core/policy_engine.py` (NEW — PolicyEngine Protocol + PolicyEngineRegistry + NullEngine)
  - `core/contract_resolver.py` (MODIFIED — invoke registry pre/post resolve)
  - `scripts/run_platform.sh` (MODIFIED — Step 5 kyverno-json parallel pass)
  - `scripts/install-kyverno-json.sh` (NEW)
  - `tests/test_policy_engine.py` (NEW — protocol conformance, registry, NullEngine)
  - `tests/test_run_platform_plan_json_policies.py` (NEW — script-substring assertion)
  - `.github/workflows/ci.yml` + `.gitea/workflows/ci.yml` (MODIFIED — Go + kj install)
- **Reason:** Owns the Python protocol layer + the pipeline wiring. The
  `PolicyEngine` Protocol + `PolicyEngineRegistry` are Python structural-
  typing constructs (PEP 544) — backend-engineer's strict-typing
  constraint. The `contract_resolver.py` wiring + `run_platform.sh`
  Step 5 are backend territory. Does NOT write kyverno-json policy
  files (policy-engineer territory) — only the Python that *invokes* the
  engine. Does NOT modify the confidence signal (it already consumes
  `list[PolicyCheckResult]` engine-agnostically — PROJECT.md hard-
  constraint).

### policy-engineer
- **Domain:** policy (declarative compliance rules)
- **Frameworks:** ["kyverno-json", "jmespath", "kyverno ValidatingPolicy"]
- **Constraints:** ["declarative-policies", "no-imperative-rules", "schema-validated", "severity-via-annotation", "assertion-trees-not-foreach"]
- **Territory:**
  - `adapters/kyverno-json/` (NEW — engine impl + __init__.py + README)
  - `adapters/kyverno-json/kyverno_json_engine.py` (NEW — KyvernoJsonEngine)
  - `adapters/kyverno-json/policies/` (NEW — all 4 target dirs: contract/, stack-ir/, plan-json/, meta/, regression/)
  - `adapters/kyverno-json/policies/_smoke.json` (NEW)
  - `adapters/README.md` (MODIFIED — new adapter row + PolicyEngine Protocol section)
  - `tests/test_kyverno_json_engine.py` (NEW — PCR schema validity, defensive parsing)
  - `tests/test_stack_ir_policies.py` (NEW)
  - `tests/test_plan_json_policies.py` (NEW)
  - `tests/test_meta_policies.py` (NEW)
  - `tests/test_regression_policies.py` (NEW)
  - `tests/fixtures/stack_ir/`, `tests/fixtures/plan_json/`, `tests/fixtures/capability_inventory.json` (NEW)
  - `modules/STANDARDS.md` (MODIFIED — Policy authoring standard section — REQ-307)
- **Reason:** The policy-engineer owns the declarative policy artifacts.
  kyverno-json's `ValidatingPolicy` + assertion trees + JMESPath is a
  distinct framework from backend-engineer's fastify/hono and requires
  its own constraints: no imperative rules (everything is an assertion
  tree), severity via the `nova.cloudinit.dev/severity` annotation (not
  in the engine adapter), no `forEach` (use the `~` modifier). The
  adapter pattern (engine ↔ protocol ↔ registry) is backend-engineer
  territory, but the policy *content* and the engine *translation*
  (`_to_pcr()`) are policy-engineer territory because they require
  kyverno-json output-shape knowledge. Created per RESEARCH.md §4 — this
  is a phase-spanning persona (active for P1..P4), not phase-specific.

### data-engineer
- **Domain:** data (config schema + structured fixtures)
- **Frameworks:** ["jsonschema", "yaml"]
- **Constraints:** ["schema-first", "type-safe config", "backward-compatible additions"]
- **Territory:**
  - `.ciagent/config.json` (MODIFIED — new `policy` object: engine + policy_root)
  - `schemas/policy_check_result.schema.json` (READ-ONLY — no change per D-116)
  - `schemas/README.md` (MODIFIED — note engine: "kyverno" shared by K8s adapter + kj)
  - `tests/fixtures/capability_inventory.json` (NEW — clean + drifted inventory fixtures for regression policies)
- **Reason:** The `config.json.policy` object is a schema-first addition
  (new top-level key with `engine` + `policy_root` fields). The
  capability-inventory JSON fixtures for the regression-gate policies
  (REQ-304) are structured data — the data-engineer owns the fixture
  shape. The `policy_check_result.schema.json` is read-only (D-116 — no
  enum change); the data-engineer documents the `engine: "kyverno"`
  sharing in `schemas/README.md`. No migrations (no database). No Python
  (backend-engineer + policy-engineer territory).

## Deactivated personas

### frontend-engineer
- **active:** false
- **Reason:** ACDL has no frontend (no package.json — confirmed in
  config.json personas.personas[frontend-engineer].reason). v1.25 adds
  no UI work — the policy engine is backend + policy artifacts only.
  Deactivated per the v1.15+ convention.
