"""E2E tests for transient network failures.

Verifies the lifecycle degrades gracefully when external dependencies are
flaky:

* RSS feed unreachable -> trigger ``event_source='rss'`` falls back to
  the hardcoded sample.
* Anthropic 503 once + 200 retry -> lifecycle succeeds.
* Arc RPC disconnect mid-bid-submit -> other agents still bid, lifecycle
  continues (mock_bids path stays resilient).
* Polymarket Gamma 503 in dry_run -> lifecycle still reaches SUBMITTED
  with simulated fallback.

All tests rely on monkey-patched httpx clients so no real network hits.
