feat(P42): stub implementation — SoD, HITL gates, attestation matrix, Wiz, Kyverno

project: acdl
phase: 42
milestone: v1.9
status: execute
---/ci---

Phase 42 — stub-implementation (REQ-107..111, D-084):

route_halt_artifact (REQ-107):
- core/separation_of_duties.py: real SNS publish (ACDL_SOD_HALT_TOPIC_ARN)
  + outbox fallback (SEPARATION_OF_DUTIES_VIOLATION event via
  outbox_writer) + stderr emission. No silent print-only stub.
- terraform/platform/main.tf: aws_sns_topic.acdl-sod-halt + output.

HITL attestation gates (REQ-108):
- core/hitl_gates.py: attest(contract_id, env, approver, evidence,
  outbox_client) records approver_qa/approver_prod/approver_dr to
  outbox, runs SoD check on prod, invokes attestation matrix, returns
  (ok, reason). Dev skips (autonomous). approver_from_env() reads
  GITHUB_ACTOR/GITEA_ACTOR.
- scripts/run_platform.sh: Step 7b HITL gate before apply for qa/prod/dr.

8-concern attestation matrix (REQ-109, D-084):
- core/attestation_matrix.py: check(env, evidence) runs the 8 concerns
  from hitl_matrix_design.md §10.4. Offline-testable (contract_nfrs,
  schema_validity, policy_pass) run for real. Operator-supplied accept
  signed artifacts validated for freshness (FRESHNESS_DAYS table) +
  schema. Signature skip when ACDL_ATTESTATION_SIGNING_KEY_ID unset
  (D-089). Fail loud if missing/expired for prod/dr.

Wiz real client (REQ-110):
- adapters/wiz/wiz_adapter.py: WizClient (GraphQL API, Bearer auth,
  pagination via pageInfo.hasNextPage + endCursor). fetch_and_adapt
  translates issues → PolicyCheckResult; graceful degrade when
  WIZ_API_TOKEN/WIZ_API_URL unset.

Kyverno fleshed out (REQ-111):
- adapters/kyverno/kyverno_adapter.py: full PolicyReport →
  PolicyCheckResult mapping (pass/fail/skip/warn + severity + skip-with-
  reason + resource ref construction from kind/name/namespace).
  adapt_inactive() emits KYVERNO_INACTIVE_TF_STACK guard. --kube-version
  stub parsed for future GitOps.

Tests: +47 (test_route_halt_artifact.py, test_hitl_gates.py,
test_attestation_matrix.py, test_wiz_adapter_real_client.py, expanded
test_kyverno_adapter.py). Existing wiz_adapter tests updated for the
real client's control.name ruleId. 493 passed; run_ci.sh green;
run_platform.sh --check-only green.
