Research direction

The failing tests are in crates/registry-language-server/tests/evidence_cards_protocol.rs. Look for the MESSAGE_TIMEOUT constant at line 631. First, run the tests under load to reproduce the flakiness. Check sibling protocol test files for the same constant. The fix is to adjust the timeout or change the waiting strategy. Verify by rerunning the full test suite.

Description

area:evidence bug

Tests in crates/registry-language-server/tests/evidence_cards_protocol.rs fail under machine load because MESSAGE_TIMEOUT is 10 seconds (line 631). Seen on macOS on 2026-09-24 during full-crate runs beside other builds; they pass when rerun alone.

Next step: reproduce under contention and raise or scale the timeout, or wait on the specific protocol message without a short wall-clock bound. Check the sibling protocol test files for the same constant.
