qa-detect-network-errors

What it checks

HTTP 4xx/5xx responses and failed requests captured during navigation.

Orchestrator flow (uses Playwright MCP network APIs)

1. BEFORE navigate, call browser_network_requests() (start fresh capture).
2. Navigate to cell route.
3. AFTER navigation completes, call browser_network_requests() to read all collected requests.
4. Filter + transform per rules below.

Rules

• Skip any URL containing favicon.
• For each response with status >= 400:
  • status >= 500 → httpError (critical)
  • status >= 400 → httpError (high)
• For each requestfailed → requestFailed (high)
