+# Network-First Safeguards
+
+- Register interceptions before any navigation or user action; store the promise and await it immediately after the triggering step.
+- Assert on structured responses (status, body schema, headers) instead of generic waits so failures surface with actionable context.
+- Capture HAR files or Playwright traces on successful runs—reuse them for deterministic CI playback when upstream services flake.
+- Prefer edge mocking: stub at service boundaries, never deep within the stack unless risk analysis demands it.
+- Replace implicit waits with deterministic signals like `waitForResponse`, disappearance of spinners, or event hooks.
