 Q2 CLAIMED; awaiting Adversary cold-verify. Continuing on Q3 (SSO-dependent suite) in parallel.
+
+## 2026-05-28 — Q2 FAIL on F2-5; fixed; RE-CLAIMED
+
+Adversary FAILed Q2 on three findings:
+- **F2-5 (gate-blocker):** `teardown_deps` silently suppressed teardown failures via
+  `contextlib.suppress(Exception)`. The `===== DEPS teardown =====` print fired even when undeploy
+  raised. On Adversary cold-check 14+ minutes after my Q2.4 run, the dep keycloak stack
+  `keyc-c12afe` was STILL UP — 2 services + leftover secrets/volumes. The "green" Q2.4 run leaked.
+- **F2-6 (secondary):** cold keycloak install flake (502 from /realms/master). Real issue, but
+  unrelated to Q2 acceptance — flagged for future infra hardening.
+- **F2-7 (transparency):** SSO setup is keycloak-hardcoded; `setup_authentik_realm` would need a
+  parallel backend. Documented for Q5 to avoid skipping authentik on the false premise that the
+  harness is reusable for it.
+
+**This explained my Q3.1 flake!** When I ran lasuite-docs+keycloak again after the Q2.4 run, the
+dep domain (`keyc-c12afe.ci.commoninternet.net` — deterministic per parent+dep+pr+ref) was the
+SAME, and the leftover stack from Q2.4 collided with the new deploy. The "502 from /realms/master"
+was actually the OLD stack still running, but trying to deploy a fresh keycloak on top of the
+existing one. The new abra app new succeeded (created a new .env), but the swarm services were
+already running so abra app deploy did weird things, and Traefik routed to the OLD running stack
+(which was timing out / not healthy after the secrets had been swapped).
+
+**Fix (commit `c6e94af`):**
+- `deps.py::teardown_deps`: switched to `verify=True` so `lifecycle.teardown_app` raises on
+  residuals; loop catches per-dep failures, logs LOUDLY, but continues to teardown other deps;
+  after all attempts, raises a combined `TeardownError`.
+- `run_recipe_ci.py`: catches the dep `TeardownError` in finally; surfaces via
+  `dep_teardown_error` in the summary + non-zero exit code; run still prints diagnostics so a
+  teardown failure doesn't hide other failures.
+
+**Cold-verified e2e** (log `/root/ccci-f25-verify.log`):
+```
+RECIPE=lasuite-docs STAGES=install,custom cc-ci-run runner/run_recipe_ci.py
+===== DEPS: ['keycloak'] =====
+  dep: deploying keycloak -> keyc-c12afe.ci.commoninternet.net
+  dep: keycloak ready @ keyc-c12afe.ci.commoninternet.net
+===== TIER: install =====   2 PASS
+===== TIER: custom =====    3 PASS (incl. test_oidc_password_grant_against_dep_keycloak)
+===== DEPS teardown =====
+  dep: tearing down keycloak @ keyc-c12afe.ci.commoninternet.net
+===== RUN SUMMARY =====
+deploy-count = 2 (expect 2)
+```
+
+Post-run cc-ci state (verified 30s later): `docker stack ls | grep keyc` → empty;
+`docker volume ls | grep keyc` → empty; `docker secret ls | grep keyc` → empty. No leak.
+
+Side-effect of the cleanup: also landed Q3.1 partial (PARITY.md + 2 new functional tests for
+lasuite-docs — test_health_check parity port + test_auth_required showing 401 on protected API).
+test_oidc_with_keycloak.py is the third specific test (Q2.4 acceptance + Q3.1 OIDC coverage).
+
+**Lessons:**
+1. **Silent exception suppression in cleanup paths is a bug**, not robustness. Use it ONLY for
+   things you know are inherently best-effort and don't have downstream effects. Dep teardown
+   has downstream effects (deterministic dep domain → next-run collision); it MUST be loud.
+2. **Deterministic per-run domains amplify state leaks.** When parent+pr+ref+dep produces the
+   same hash on a re-run, any leak from the prior run silently corrupts the next. The fix
+   options were either (a) make teardown sacred (chosen — F2-5 fix), or (b) make the domain
+   random/timestamped. (a) is right because deterministic helps debugging and concurrent-safety
+   when verified to fully teardown.
+
+Q2 RE-CLAIMED. Continuing Q3 work in parallel.
