From ac18c983853b7ca2274edb665fb781cfca5417fe Mon Sep 17 00:00:00 2001 From: Jon Chery Date: Wed, 12 Aug 2026 18:19:16 +0000 Subject: [PATCH 1/2] feat(P1): kyverno-json engine core + PolicyEngine protocol (REQ-291..294, 308, 309) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit core/policy_engine.py: PolicyEngine Protocol (PEP 544, runtime_checkable) + PolicyEngineRegistry (selects from config.json.policy.engine) + NullEngine fallback (NULL_ENGINE_INACTIVE when policy key absent). adapters/kyverno-json/: KyvernoJsonEngine — shells to , translates native output → list[dict] PCR records (engine: "kyverno", ruleId KJ_ prefix, severity via nova.cloudinit.dev/severity annotation, default info). is_configured() guards on → KJ_ENGINE_NOT_CONFIGURED SKIPPED PCR (distinct from NullEngine). Defensive parsing (malformed → error PCR). config.json: new object {engine: kyverno-json, policy_root}. scripts/install-kyverno-json.sh: go install kj@latest (D-115). CI (.gitea + .github): install Go + kj for policy-engine tests (best-effort; tests skip when kj absent). tests: 24 pass, 2 skip (kj not installed). 132 existing tests unchanged. NullEngine satisfies PolicyEngine Protocol (G-Q8a — proves swap boundary). ---ci--- project: acdl phase: 1 milestone: v1.25 status: execute phase_role: execution requirements: covered: [REQ-291, REQ-292, REQ-293, REQ-294, REQ-308, REQ-309] partial: [] ---/ci--- --- .ciagent/config.json | 6 +- .gitea/workflows/ci.yml | 17 ++ .github/workflows/ci.yml | 15 ++ adapters/kyverno-json/__init__.py | 27 ++ adapters/kyverno-json/kyverno_json_engine.py | 269 +++++++++++++++++++ adapters/kyverno-json/policies/_smoke.json | 30 +++ core/policy_engine.py | 212 +++++++++++++++ scripts/install-kyverno-json.sh | 35 +++ tests/test_kyverno_json_engine.py | 213 +++++++++++++++ tests/test_policy_engine.py | 125 +++++++++ 10 files changed, 948 insertions(+), 1 deletion(-) create mode 100644 adapters/kyverno-json/__init__.py create mode 100644 adapters/kyverno-json/kyverno_json_engine.py create mode 100644 adapters/kyverno-json/policies/_smoke.json create mode 100644 core/policy_engine.py create mode 100644 scripts/install-kyverno-json.sh create mode 100644 tests/test_kyverno_json_engine.py create mode 100644 tests/test_policy_engine.py diff --git a/.ciagent/config.json b/.ciagent/config.json index 674a825..acbcece 100644 --- a/.ciagent/config.json +++ b/.ciagent/config.json @@ -209,5 +209,9 @@ "enabled": true, "persist": true }, - "strategic_direction_file": ".ciagent/NORTH_STAR.md" + "strategic_direction_file": ".ciagent/NORTH_STAR.md", + "policy": { + "engine": "kyverno-json", + "policy_root": "adapters/kyverno-json/policies" + } } diff --git a/.gitea/workflows/ci.yml b/.gitea/workflows/ci.yml index 839b9bd..965138c 100644 --- a/.gitea/workflows/ci.yml +++ b/.gitea/workflows/ci.yml @@ -63,6 +63,23 @@ jobs: - name: Install test dependencies run: pip install -r requirements-test.txt + - name: Install kyverno-json (kj) for policy-engine tests + run: | + # v1.25: kyverno-json is the primary policy engine.
