+"""ABAC end-to-end test for the token-vend Lambda (Edge 5 item 7, INV-17).
+
+The M1.5 verification-gate spike (PLAN.md Happy Path §3.3 Edge 5 item 7):
+
+    Known PAT → known ABAC-allowed action → signed OIDC token → jose/pyjwt
+    verification → green. Known PAT + ABAC-denied action → 403 with deny
+    reason logged (INV-17 fail-closed).
+
+This is the end-to-end ABAC path: PAT → revocation check (D-229 strong
+read) → kyverno-json ABAC policy evaluation → KMS-signed OIDC token →
+JWKS fetch → pyjwt signature verification. It wires the **real**
+``core.abac_evaluator.evaluate_token_vend_policy`` (which shells to the
+``kj`` binary against ``platform/abac/token-vend.policy``) behind the
+token-vend Lambda handler, then verifies the vended OIDC token against
+the JWKS the JWKS Lambda would serve — exactly the M1.5 spike shape.
+
+## Two execution surfaces (REQ-362 covered-reference)
+
+* **acdl CI** — ``kj`` is NOT installed (``which kj`` is absent) and
+  there is no live KMS key. The ABAC-allowed and ABAC-denied tests
+  therefore ``pytest.skip`` with a clear reason (the ``kj`` binary is a
+  build-host/nova-platform-ops dep). The fail-closed (policy-absent)
+  test runs in acdl CI because it does NOT need ``kj`` — it exercises
+  the ``is_configured()``-False → 403 ``abac_eval_failed`` path.
+* **nova-platform-ops CI** — ``kj`` is present at ``/opt/kj/kj`` and the
+  live KMS key ``alias/nova-oidc-signing`` is reachable. The
+  ABAC-allowed/denied tests run against the real binary + a mock KMS
+  (or the live key when marked ``live_aws``).
+
+## Test deps
+
+* ``moto[dynamodb]`` — mocks ``nova-pats`` (revocation strong read).
+* mock KMS via ``cryptography`` generated ECDSA P-256 keypair (the same
+  pattern as ``tests/test_kms_roundtrip.py`` + ``test_pat_revocation.py``).
+* ``pyjwt`` — verifies the vended OIDC token against the JWKS the JWKS
+  Lambda serves (the ``jose``-equivalent verification in the plan; the
+  repo standardizes on ``pyjwt`` + ``cryptography``, no ``jose`` dep).
