# NousResearch/hermes-agent · FTS5 index errors wrongly treated as fatal corruption

## Open now

- Nothing open on GitHub.

These issues and fixes address a bug where errors in the FTS5 full-text search index layer of state.db incorrectly trigger fail-close behavior on turns, causing dropped messages and unnecessary destructive recovery advice. The proposed fix changes the system to fail open on FTS-index-only errors while reserving stricter handling for genuine structural corruption.
