+"""lasuite-docs — Q2 SSO-flow acceptance test (Phase 2 §6 Q2 gate).
+
+The plan §6 Q2 acceptance is: "a dependent recipe can deploy a provider and run an OIDC login test
+in one run." This test exercises that contract end-to-end:
+
+1. The orchestrator deployed a **per-run keycloak** as lasuite-docs's declared dep
+   (`recipe_meta.DEPS = ["keycloak"]`). Its domain is in `deps_apps["keycloak"]`.
+2. Use the shared SSO-setup harness primitive (`runner/harness/sso.py`) to create a realm + OIDC
+   client + test user in the dep keycloak — idempotent, with cc-ci-controlled identifiers.
+3. Exercise the OIDC discovery endpoint (`.well-known/openid-configuration`); assert issuer is
+   the per-run keycloak's `/realms/<realm>`.
+4. Perform the **OIDC password grant** against the dep keycloak; assert the returned access_token
+   is a valid JWT with the expected claims (iss = provider/realm, azp = the OIDC client, exp in
+   future). This is the canonical "OIDC login" flow — the user-equivalent token issuance — that
+   proves the SSO subsystem is intact.
+
+Non-vacuous: a keycloak with broken admin API would fail at setup; a broken token endpoint would
+fail at password grant; wrong claims would fail JWT validation. Each step uses real credentials
+generated for THIS run (class-B per §4.4-B); destroyed when the dep is torn down at run end.
+
+This test does NOT yet exercise lasuite-docs's own OIDC-protected endpoints — those would require
+wiring the client_secret + OIDC env into lasuite-docs at install time (a future Q3.1 task; see
+DECISIONS.md). What it proves NOW is the **dep resolver + SSO-setup harness** end-to-end, which is
+exactly the Q2 gate acceptance: a dependent recipe deploys its provider and runs an OIDC test.
