"""E2E tests for failure paths in the lifecycle.

Covers:
* Hard-gate (D5) judge failure -> REJECTED
* Low MQM score -> REJECTED
* No bids -> FAILED with reason='no_bids' (no synthetic fallback)
* All bidders below reputation gate -> orchestrator's documented fallback
* On-chain commit hang -> 90s timeout -> pending sentinel

All tests use MockLLM (no live Anthropic) and the orchestrator's
``mock_bids`` knob.
