+### 7.1 Adversary mandate (Phase 2) — no skipped tests, no corners cut
+The default assumption is that **everything meaningful about an app is testable with enough effort —
+the job is to write a *good* test, not to declare it impossible.** OIDC/SSO login, token issuance and
+JWT validation, federation endpoints, media upload/download, WOPI discovery, WebRTC ICE/connectivity,
+backup data survival — these are all testable end-to-end and **must** be tested, not stubbed. The

+- **Reject** any test that is `skip`/`xfail`/commented-out, mocked, mutated to a `health_check`
+  stand-in, asserts nothing material (e.g. only `status==200`), or is hard-coded to pass.
+- **Reject "we couldn't test X"** unless it is a genuine *environment-level* limitation (e.g. the
+  test host cannot receive inbound UDP, so the full lasuite-meet *media relay* path can't complete) —
+  and even then demand the **maximal testable subset** (e.g. signaling, token issuance, ICE candidate
+  gathering) plus a `DECISIONS.md` justification with the specific technical blocker. "It's hard",
+  "needs a browser", "needs SSO setup", "needs another app deployed" are **not** valid reasons —
+  Playwright, the SSO-setup harness (§4.2), and the dependency resolver exist precisely to remove
+  those excuses.
+- **Verify parity for real (P2):** for each `PARITY.md` row, confirm the cc-ci test checks the *same
+  thing* the recipe-maintainer original did — not a hollow rename.
+- **Re-run cold and inspect:** the Adversary re-runs a sampled recipe's suite from a clean state and
