## Open now

- 0 issues, 2 PRs open on GitHub.
- PR #100239: fix(state): catch segment-dependent FTS corruption in the health probe
- PR #100244: fix(state): commit FTS health probe so trigram idx collisions are visible

These issues and fixes address cases where segment-dependent or content-dependent FTS trigram index corruption goes undetected by the health probe and repair tooling. The work focuses on improving the probe's ability to surface these corruption scenarios rather than silently missing them.

## TL;DR
