# PLAN — v1.25 (kyverno-json Unified Policy Engine)

> Feature milestone. Tags on the **v1.24.x** line: v1.24.0 (P0) →
> v1.24.1 (P1) → v1.24.2 (P2) → v1.24.3 (P3) → v1.24.4 (P4) → v1.24.5
> (P5 final = milestone release). 19 requirements (REQ-291..309),
> 4 execution phases + P0 pre-execution + P5 final review/ship.

## Wave model

Each phase is a **vertical slice** (end-to-end: policy files + Python
wiring + tests + docs). Phases are ordered by dependency: the engine
protocol (P1) must exist before policies (P2/P3) can be wired; the
pipeline wiring (P3) must exist before the meta-policies (P3) can
consume the merged PCR list; the regression-gate policies (P4) are
independent of the pipeline and can be authored in parallel with P3's
tests, but ship after P3 because they reference the engine registry
finalized in P1. Within each phase, the waves are the persona task
groups (parallelizable across personas when `parallelization.enabled:
true`, `max_concurrent_agents: 5`).

## Phase breakdown

### Phase P1 — engine-core (Wave 1, backend-engineer + policy-engineer + data-engineer)

**Type:** `feat` (engine protocol + registry + kyverno-json engine adapter + install + tests)

**Requirements:** REQ-291, REQ-292, REQ-293, REQ-294, REQ-308, REQ-309

**Must-haves:**
- `core/policy_engine.py` — `PolicyEngine` Protocol (PEP 544) +
  `PolicyEngineRegistry` (selects from `config.json.policy.engine`) +
  `NullEngine` fallback (emits `SKIPPED` when `policy` key absent)
  (REQ-291)
- `.ciagent/config.json` gains `policy` object: `{"engine":
  "kyverno-json", "policy_root":
  "adapters/kyverno-json/policies"}` (REQ-292)
- `adapters/kyverno-json/kyverno_json_engine.py` — `KyvernoJsonEngine`
  implementing the protocol: `is_configured()` guards on `which kj`;
  `evaluate()` writes payload to temp JSON, invokes
  `kj scan --policy <dir> --payload <json> --output json`, translates
  native output → `list[dict]` PCR records (`engine: "kyverno"`,
  `ruleId` prefixed `KJ_<policy_name>`, severity from
  `nova.cloudinit.dev/severity` annotation); defensive parsing
  (malformed → `error` PCR, never exception); `is_configured()==false`
  → single `SKIPPED` PCR (`KJ_ENGINE_NOT_CONFIGURED`) (REQ-293)
- `adapters/kyverno-json/__init__.py` exports `KyvernoJsonEngine`;
  `adapters/kyverno-json/policies/_smoke.json` trivial
  `require-contract-id` policy for round-trip validation;
  `scripts/install-kyverno-json.sh` runs
  `go install github.com/kyverno/kyverno-json/cmd/kj@latest`;
  `.github/workflows/ci.yml` + `.gitea/workflows/ci.yml` install Go + kj
  (cached) (REQ-294)
- `tests/test_policy_engine.py` — protocol conformance, registry
  selection, unknown-engine `KeyError`, `NullEngine` fallback,
  `is_configured()` false when `which kj` absent (mocked) (REQ-308)
- `tests/test_kyverno_json_engine.py` — `evaluate()` returns PCR dicts
  validating against `schemas/policy_check_result.schema.json` (via
  `jsonschema`); defensive parsing (malformed kyverno-json output →
  `error` PCR); `is_configured()==false` → `SKIPPED` with
  `KJ_ENGINE_NOT_CONFIGURED`; `pytest.skip("kj not installed")` when
  `which kj` absent (REQ-309)

**Vertical slice:** The `PolicyEngineRegistry.get_engine()` returns a
configured `KyvernoJsonEngine` that can `evaluate()` a trivial payload
against `_smoke.json` and produce a valid PCR list. The confidence
signal is unchanged — it already consumes `list[PolicyCheckResult]`.
The platform runs with or without the `kj` binary (`is_configured()`
guard). All existing tests pass (NullEngine fallback when `policy` key
absent in test config — but the v1.25 config.json *sets* the key, so
existing tests that use the real config get `KyvernoJsonEngine` with
`is_configured()==false` → `SKIPPED`).

**Files touched:**
- `core/policy_engine.py` (NEW)
- `.ciagent/config.json` (MODIFIED — `policy` object)
- `adapters/kyverno-json/__init__.py` (NEW)
- `adapters/kyverno-json/kyverno_json_engine.py` (NEW)
- `adapters/kyverno-json/policies/_smoke.json` (NEW)
- `scripts/install-kyverno-json.sh` (NEW)

- `.gitea/workflows/ci.yml` (MODIFIED — Go + kj install step)
- `tests/test_policy_engine.py` (NEW)
- `tests/test_kyverno_json_engine.py` (NEW)

**Verification:** `pytest tests/test_policy_engine.py
tests/test_kyverno_json_engine.py tests/test_confidence_signal.py
tests/test_adapter.py tests/test_checkov_adapter.py
tests/test_kyverno_adapter.py -v` (new tests pass or skip-without-kj;
existing adapter/confidence tests unchanged). `python3 -m py_compile
core/policy_engine.py adapters/kyverno-json/kyverno_json_engine.py`.

---

### Phase P2 — contract + stack-IR policies (Wave 2, policy-engineer + backend-engineer)

**Type:** `feat` (policies + resolver wiring + tests)

**Requirements:** REQ-295, REQ-296, REQ-297, REQ-298, REQ-299

**Must-haves:**
- `adapters/kyverno-json/policies/contract/` — 4 policies over consumer
  contract JSON: `require-id-pattern.json`,
  `require-env-in-enum.json`, `require-infrastructure-min-1.json`,
  `forbid-unknown-fields.json` — each a `ValidatingPolicy` with one
  `validate.assert` rule using JMESPath against the payload root;
  severity via `nova.cloudinit.dev/severity` annotation (REQ-295)
- `core/contract_resolver.py` invokes
  `PolicyEngineRegistry.get_engine().evaluate(contract_dict,
  policies/contract/, contract_id)` **before** resolving; failures
  feed the `policy` input as `fail` PCRs (no resolver exit — confidence
  signal decides the gate, `--soft-fail` pattern); emits
  `nova.policy.evaluated` metrics event (REQ-296)
- `adapters/kyverno-json/policies/stack-ir/` — 3 policies over
  resolved Stack IR: `require-tagging-standard.json` (ports
  `nova_tagging.py` — `nova:owner` + `nova:environment` tags on every
  `resources[]` entry), `forbid-public-ingress.json` (v1.0 demo rule),
  `require-encryption-by-default.json` (v1.8 D-encryption-default);
  `~` modifier iterates `resources[]` (REQ-297)
- `core/contract_resolver.py` invokes the engine with the resolved
  Stack IR and `policies/stack-ir/` **after** resolving; resulting PCRs
  appended to the contract-policy PCRs; resolver return values and
  exceptions unchanged (additive) (REQ-298)
- `tests/test_stack_ir_policies.py` + `tests/fixtures/stack_ir/` —
  passing IR (all tags + encryption) + failing IR (missing tags, public
  ingress, plaintext bucket); each policy in isolation + full dir as
  bundle; `pytest.skip("kj not installed")` when `which kj` absent
  (REQ-299)

**Vertical slice:** A consumer contract passes through the resolver
and produces two PCR lists (contract policies pre-resolve, stack-IR
policies post-resolve) that feed the confidence signal. A contract
with a bad `id` or missing tags produces `fail` PCRs that lower the
confidence score. The resolver's existing tests pass unchanged (the
policy call is additive — it does not change resolver return values
or exceptions).

**Files touched:**
- `adapters/kyverno-json/policies/contract/require-id-pattern.json` (NEW)
- `adapters/kyverno-json/policies/contract/require-env-in-enum.json` (NEW)
- `adapters/kyverno-json/policies/contract/require-infrastructure-min-1.json` (NEW)
- `adapters/kyverno-json/policies/contract/forbid-unknown-fields.json` (NEW)
- `adapters/kyverno-json/policies/stack-ir/require-tagging-standard.json` (NEW)
- `adapters/kyverno-json/policies/stack-ir/forbid-public-ingress.json` (NEW)
- `adapters/kyverno-json/policies/stack-ir/require-encryption-by-default.json` (NEW)
- `core/contract_resolver.py` (MODIFIED — pre/post resolve engine calls)
- `tests/test_stack_ir_policies.py` (NEW)
- `tests/fixtures/stack_ir/passing.json` (NEW)
- `tests/fixtures/stack_ir/failing.json` (NEW)

**Verification:** `pytest tests/test_contract_resolver.py
tests/test_stack_ir_policies.py tests/test_policy_engine.py -v`
(existing resolver tests pass; new policy tests pass or skip-without-
kj). `python3 -m py_compile core/contract_resolver.py`.

---

### Phase P3 — plan-JSON policies + meta-orchestration + pipeline wiring (Wave 3, policy-engineer + backend-engineer)

**Type:** `feat` (plan-JSON policies + meta-policies + run_platform.sh wiring + tests)

**Requirements:** REQ-300, REQ-301, REQ-302, REQ-303

**Must-haves:**
- `adapters/kyverno-json/policies/plan-json/` — 3 policies over
  `terraform show -json` output: `forbid-plaintext-secrets.json` (ports
  CKV_AWS_41/45/46), `forbid-iam-wildcard.json` (ports CKV_AWS_1/40),
  `require-kms-reference.json` (ports CKV_AWS_7/33); JMESPath over
  `planned_values.root_module.resources[]` (REQ-300)
- `run_platform.sh` Step 5 gains a parallel kyverno-json pass: after
  Checkov/Wiz produce raw PCRs, the script runs
  `kj scan --policy adapters/kyverno-json/policies/plan-json/
  --payload <tfshow.json> -o json` and pipes through
  `adapters/kyverno-json/kyverno_json_engine.py` to produce a second
  PCR list; both lists concatenated and fed to the confidence signal;
  `nova.policy.evaluated` event with both engine names; when
  `which kj` is false, logs and proceeds with Checkov/Wiz list only
  (no hard failure) (REQ-301)
- `tests/test_plan_json_policies.py` + `tests/fixtures/plan_json/` —
  passing plan (no secrets, no wildcard, KMS alias) + failing plan
  (plaintext password, `Action: "*"`, inline KMS key); policies in
  isolation + bundle; `tests/test_run_platform_plan_json_policies.py`
  asserts `run_platform.sh` has the kyverno-json Step 5 block +
  concatenates PCR lists (script-substring assertion, pattern from
  `tests/test_pipeline.py:79-95`) (REQ-302)
- `adapters/kyverno-json/policies/meta/` — `block-on-any-critical.json`
  (asserts no PCR in merged list has `severity: critical` + `result:
  fail`; if any does, emits `fail` PCR `KJ_META_BLOCK_CRITICAL`
  severity `critical` — declarative source of truth; the
  `confidence_signal.py` hard-override stays as defense-in-depth per
  D-119) + `tagging-rules-agree.json` (cross-checks Checkov
  `NOVA_TAG_NAMING` vs kj `KJ_REQUIRE_TAGGING_STANDARD` by
  `resourceRef`; divergence emits `error` PCR per D-118);
  `tests/test_meta_policies.py` (REQ-303)

**Vertical slice:** `run_platform.sh` Step 5 produces a merged PCR list
(Checkov/Wiz + kj plan-JSON policies + kj meta-policies over the
merged list) that feeds the confidence signal. A plan with a plaintext
secret produces two `fail` PCRs (one Checkov, one kj) for the same
resource — visible defense-in-depth. A critical finding anywhere
produces a `KJ_META_BLOCK_CRITICAL` meta-PCR that the confidence
signal's hard-override blocks. The pipeline runs with or without `kj`
(graceful skip).

**Files touched:**
- `adapters/kyverno-json/policies/plan-json/forbid-plaintext-secrets.json` (NEW)
- `adapters/kyverno-json/policies/plan-json/forbid-iam-wildcard.json` (NEW)
- `adapters/kyverno-json/policies/plan-json/require-kms-reference.json` (NEW)
- `adapters/kyverno-json/policies/meta/block-on-any-critical.json` (NEW)
- `adapters/kyverno-json/policies/meta/tagging-rules-agree.json` (NEW)
- `scripts/run_platform.sh` (MODIFIED — Step 5 kj parallel pass)
- `tests/test_plan_json_policies.py` (NEW)
- `tests/test_meta_policies.py` (NEW)
- `tests/test_run_platform_plan_json_policies.py` (NEW)
- `tests/fixtures/plan_json/passing.json` (NEW)
- `tests/fixtures/plan_json/failing.json` (NEW)

**Verification:** `pytest tests/test_plan_json_policies.py
tests/test_meta_policies.py tests/test_run_platform_plan_json_policies.py
tests/test_pipeline.py -v` (new tests pass or skip-without-kj; existing
pipeline tests pass). `python3 -m py_compile` on any modified Python.
Shellcheck on `run_platform.sh` if available.

### Phase P4 — regression-gate policies + docs (Wave 4, policy-engineer + data-engineer + lead-developer)

**Type:** `feat` (regression policies) + `docs` (adapter READMEs + ARCHITECTURE + STANDARDS + METRICS)

**Requirements:** REQ-304, REQ-305, REQ-306, REQ-307

**Must-haves:**
- `adapters/kyverno-json/policies/regression/` — 3 policies over
  capability-inventory JSON frontmatter: `cap-013-adapter-dedup.json`,
  `cap-023-metrics-collector.json`, `cap-024-deck-structure.json`;
  emit `pass`/`fail` PCRs per capability; the existing
  `core/regression_verify.py` is kept (drives the CI gate); the
  policies are the declarative mirror (REQ-304)
- `tests/test_regression_policies.py` +
  `tests/fixtures/capability_inventory/clean.json` +
  `tests/fixtures/capability_inventory/drifted.json` — clean (all caps
  pass) + drifted (duplicate adapter, missing metric status, broken
  deck arc); regression gate still 287/287 baseline (new tests
  additive, skip-without-kj) (REQ-305)
- `adapters/README.md` gains new kyverno-json adapter row + "Policy
  Engine Protocol" section (Protocol, registry, swap boundary,
  how-to-add-OpaEngine); `adapters/kyverno-json/README.md` documents
  the engine, install path, policy directory layout, 4 policy
  categories (REQ-306)
- `.ciagent/ARCHITECTURE.md` §12.7 (added in RESEARCH) is finalized;
  `schemas/README.md` notes `engine: "kyverno"` shared by K8s adapter
  + kj (distinguished by `ruleId` prefix); `modules/STANDARDS.md`
  gains "Policy authoring standard" section for module owners;
  `docs/METRICS.md` notes the policy engine is swappable (Strategic
  Objective #2 — provable trust via a replaceable substrate) (REQ-307)

**Vertical slice:** The regression gate's capability checks are now
declarative policies auditable as artifacts. A new module owner can
read `modules/STANDARDS.md` "Policy authoring standard" and write a
per-module kyverno-json policy. A new engineer can read
`adapters/README.md` "Policy Engine Protocol" and implement an
`OpaEngine`. The 287/287 baseline is unchanged.

**Files touched:**
- `adapters/kyverno-json/policies/regression/cap-013-adapter-dedup.json` (NEW)
- `adapters/kyverno-json/policies/regression/cap-023-metrics-collector.json` (NEW)
- `adapters/kyverno-json/policies/regression/cap-024-deck-structure.json` (NEW)
- `tests/test_regression_policies.py` (NEW)
- `tests/fixtures/capability_inventory/clean.json` (NEW)
- `tests/fixtures/capability_inventory/drifted.json` (NEW)
- `adapters/README.md` (MODIFIED — new row + PolicyEngine Protocol section)
- `adapters/kyverno-json/README.md` (NEW)
- `schemas/README.md` (MODIFIED — engine enum note)
- `modules/STANDARDS.md` (MODIFIED — Policy authoring standard section)
- `docs/METRICS.md` (MODIFIED — swappable engine narrative)

**Verification:** `pytest tests/test_regression_policies.py
tests/test_kyverno_json_engine.py -v` (new tests pass or skip-without-
kj). Full regression gate `pytest tests/` still at 287/287 baseline +
new tests (skip without kj). Manual read of `adapters/README.md` +
`adapters/kyverno-json/README.md` + `modules/STANDARDS.md` policy
section for clarity.

---

### Phase P5 — final review + audit + milestone ship (Final Phase)

**Type:** `docs` (review + audit + milestone completion)

**Requirements:** All REQ-291..309 (mark complete)

**Must-haves:**
- `ciagent-review` multi-persona code review across P1..P4
  (lead-developer, backend-engineer, data-engineer, policy-engineer).
  Auto-fix P0; flag P1+ for post-hoc review. If P1+ issues found, fix
  them in this final phase (not loop back to EXECUTE).
- `ciagent-audit` — reconstruction test (git log ↔ `.ciagent/` files),
  `.ciagent/` file discipline, branch hygiene, commit discipline.
  Critical issues fixed in this phase.
- `ciagent-ship` (milestone) — merge `phase/05-final-review-ship` →
  `milestone/v1.25-kyverno-json` → `main`; tag `v1.24.5` (= the v1.25
  release per the prev-minor tagging rule); create Gitea release with
  full milestone summary (all phases, all requirements); delete all
  milestone branches (local + remote).
- Update `REQUIREMENTS.md` (mark REQ-291..309 complete),
  `ROADMAP.md` (mark v1.25 complete), `CHECKPOINT.json`
  (milestone_complete: true), `NORTH_STAR.md` (note Strategic
  Objective #2 — provable trust via a replaceable policy-engine
  substrate).

**Vertical slice:** The v1.25 milestone is complete: kyverno-json is
the primary policy tool, behind a swappable adapter, with policies
over all 4 Nova artifacts. Tags v1.24.0..v1.24.5 on the v1.24.x line.
The milestone branch merges to main.

**Verification:** `pytest tests/ -v` full suite passes (287 baseline +
new tests). `git log --oneline` shows the v1.25 phase commits.
`git tag` shows v1.24.0..v1.24.5. `git branch` shows no leftover
milestone/phase branches (all deleted post-ship).

---

## Wave ordering (parallelization)

With `parallelization.enabled: true`, `max_concurrent_agents: 5`,
`min_plans_for_parallel: 2`:

- **P1 Wave 1:** backend-engineer (protocol + registry + install) ‖
  data-engineer (config.json policy object) ‖ policy-engineer (engine
  adapter + smoke policy). 3 concurrent personas. Merge in order:
  data-engineer → backend-engineer → policy-engineer.
- **P2 Wave 2:** policy-engineer (contract + stack-IR policies) ‖
  backend-engineer (resolver wiring — depends on P1 registry). 2
  concurrent. Merge: policy-engineer → backend-engineer (wiring
  references the policy dirs).
- **P3 Wave 3:** policy-engineer (plan-JSON + meta policies) ‖
  backend-engineer (run_platform.sh wiring — depends on P1 engine +
  P2 resolver pattern). 2 concurrent. Merge: policy-engineer →
  backend-engineer.
- **P4 Wave 4:** policy-engineer (regression policies) ‖ data-engineer
  (capability-inventory fixtures) ‖ lead-developer (docs: READMEs,
  STANDARDS, METRICS). 3 concurrent. Merge: data-engineer →
  policy-engineer → lead-developer.

Territory enforcement: `warn` mode (per `config.json
personas.territory_enforcement: "warn"`). Cross-territory edits
(e.g., backend-engineer touching a policy file) emit a warning, not a
block.
