+## Policy Engine Protocol (v1.25)
+
+The `core/policy_engine.py` module defines the **swap boundary** between
+Nova and its policy engines. A `PolicyEngine` Python Protocol (PEP 544)
+with three members (`name`, `is_configured()`, `evaluate()`) is the
+contract; a `PolicyEngineRegistry` selects the active engine from
+`config.json`'s `policy.engine` key. The confidence signal and pipeline
+never import an engine directly — they go through the registry.
+
+**Implementations:**
+- `KyvernoJsonEngine` (`adapters/kyverno-json/`) — shells to the `kj`
+  CLI; the v1.25 default.
+- `NullEngine` (`core/policy_engine.py`) — fallback when the `policy`
+  key is absent (emits `SKIPPED`).
+- Future: `OpaEngine` — implements the same protocol, shells to
+  `opa eval`. The OPA-equivalent surface is documented in
+  `.ciagent/RESEARCH.md` §4.2.
+
+**How to add a new engine:**
+1. Create `adapters/<name>/<name>_engine.py` implementing the
+   `PolicyEngine` protocol (`name`, `is_configured()`, `evaluate()`).
+2. `evaluate()` returns `list[dict]` where each dict conforms to
+   `schemas/policy_check_result.schema.json`.
+3. Register the engine in `core/policy_engine.py`'s `_autoload_*`
+   function (or call `register(name, factory)` at startup).
+4. Set `config.json.policy.engine` to the engine's `name`.
+5. Add the engine to the `engine` enum in
+   `schemas/policy_check_result.schema.json` if it needs a distinct
+   enum value (v1.25 reuses `"kyverno"` — see D-116).

+# kyverno-json Engine Adapter (v1.25)
+
+The `kyverno-json` engine is Nova's **primary compliance/policy tool**
+(v1.25), implemented behind the swappable `PolicyEngine` protocol so
+OPA (or any other engine) can replace it one day.
+
+## What kyverno-json is
+
+[kyverno-json](https://github.com/kyverno/kyverno-json) is a standalone
+Go binary from the Kyverno project — a **separate runtime** from the
+K8s Kyverno admission controller. It applies Kyverno `ValidatingPolicy`
+resources to **any** JSON or YAML payload file via the `kj scan` CLI.
+Unlike the K8s Kyverno adapter (`adapters/kyverno/`), which only
+speaks to K8s manifests, kyverno-json evaluates consumer contracts,
+resolved Stack IR, terraform plan JSON, and even the merged PCR list
+itself (meta-policies).
+
+## Install
+
+```bash
+bash scripts/install-kyverno-json.sh
+# or directly:
+go install github.com/kyverno/kyverno-json/cmd/kj@latest
+kj version
+```
+
+The platform functions without the binary — `is_configured()` returns
+`False` when `which kj` is absent → `evaluate()` returns a single
+`SKIPPED` PCR (`KJ_ENGINE_NOT_CONFIGURED`). The confidence signal
+proceeds with a neutral `policy` input (D-120 graceful degradation).
+

+## The four policy categories
+
+1. **contract/** — over the consumer contract JSON (pre-resolve).
+2. **stack-ir/** — over the resolved Target Stack IR (post-resolve).
+3. **plan-json/** — over `terraform show -json` output (pipeline Step 5b).
+4. **meta/** — over the merged `list[PolicyCheckResult]` (meta-policies).
+5. **regression/** — over the capability-inventory JSON (declarative
+   mirrors of `core/regression_verify.py`).
+
+## Severity convention
+
+kyverno-json does not natively assign severities. Each Nova policy
+declares its severity via a `metadata.annotations` field:
+
+```yaml
+metadata:
+  annotations:
+    nova.cloudinit.dev/severity: high
+```
+
+Valid values: `critical`, `high`, `medium`, `low`, `info` (default
+when absent).
+
+## Engine enum reuse (D-116)
+
+kyverno-json PCR records carry `engine: "kyverno"` (no new enum value).
+The `engine` field records the policy-engine *family*, not the specific
+binary. The K8s Kyverno adapter and the kyverno-json engine are
+distinguished by `ruleId` prefix (`KYVERNO_` vs `KJ_`) and `evidence`
+payload shape (`namespace`/`kind` vs `assertion`/`jmespath`).
+
+## Schema path
+
+The output records validate against
+[`schemas/policy_check_result.schema.json`](../../schemas/policy_check_result.schema.json)
+(`engine: "kyverno"` is in the enum). The confidence signal consumes
+the merged PCR list engine-agnostically.
+
+## Swap boundary
+
+The `PolicyEngine` protocol (`core/policy_engine.py`) is the swap
+boundary. The OPA-equivalent surface is documented in
+`.ciagent/RESEARCH.md` §4.2 — a future `OpaEngine` implements the same
+protocol without touching the confidence signal, the PCR schema, or
+the pipeline.

+## v1.25 — Swappable Policy Engine
+
+The policy engine that produces the `PolicyCheckResult` records feeding
+the confidence signal is **swappable** (NORTH_STAR Strategic Objective #2
+— provable trust via a replaceable substrate, not a vendor lock-in).
+The `PolicyEngine` protocol (`core/policy_engine.py`) is the swap
+boundary; `config.json.policy.engine` selects the active engine
+(default `"kyverno-json"`). A future `OpaEngine` implements the same
+protocol without touching the confidence signal, the PCR schema, or
+the pipeline. See `.ciagent/ARCHITECTURE.md` §12.7 for the registry
+diagram.

+## 10. Policy Authoring Standard (v1.25)
+
+Module owners may ship per-module kyverno-json policies in
+`modules/<name>/policies/` (future convention; v1.25 policies live
+under `adapters/kyverno-json/policies/`). A policy file is a
+`ValidatingPolicy` resource (YAML or JSON).
+
+### 10.1 Required fields
+
+- `apiVersion: json.kyverno.io/v1alpha1`
+- `kind: ValidatingPolicy`
+- `metadata.name` — matches the filename (e.g. `require-tags.json` →
+  `name: require-tags`). This becomes the `ruleId` prefix `KJ_<name>`.
+- `metadata.annotations["nova.cloudinit.dev/severity"]` — one of
+  `critical`, `high`, `medium`, `low`, `info`. Drives the confidence
+  signal's penalty mapping.
+- `spec.rules[].validate.assert` — an `all` or `any` list of assertion
+  trees with JMESPath expressions. **No `forEach`, pattern operators,
+  anchors, or wildcards** — use the `~` projection modifier to iterate.
+
+### 10.2 Severity guidance
+
+| Severity | When to use | Confidence penalty |
+| --- | --- | --- |
+| `critical` | a violation makes the deploy unsafe (e.g. public ingress on a prod DB) | hard override (score = 0, block) |
+| `high` | a violation is a security or compliance gap (e.g. plaintext secrets) | -0.20 |
+| `medium` | a violation is a best-practice miss (e.g. missing tags) | -0.05 |
+| `low` | a violation is a style or convention issue | -0.01 |
+| `info` | a non-blocking observation (default) | 0.0 |
+
+### 10.3 Assertion-tree patterns
+
+- **Iterate an array:** use the `~` modifier on the array key:
+  ```yaml
+  check:
+    ~.resources:
+      (@ < `5`): true
+  ```
+- **Match a resource type:** use the `match.any` block:
+  ```yaml
+  match:
+    any:
+      - type: aws:s3:bucket
+  ```
+- **Binding for descendant access:** use `->name`:
+  ```yaml
+  (bar + bat)->sum:
+    ($sum): 10
+  ```
+
+### 10.4 Testing
+
+- Ship a fixture pair (`passing.json` + `failing.json`) under
+  `tests/fixtures/<policy_target>/`.
+- Add a test file `tests/test_<policy_target>_policies.py` using the
+  `KyvernoJsonEngine` (skip-without-kj pattern).
+- The regression gate (`pytest tests/`) must remain green.
