# NousResearch/hermes-agent · Unversioned config migration overwrites user values

## Open now

- Nothing open on GitHub.

These items address a bug where configs lacking a version stamp are incorrectly run through the full migration ladder, causing user-set values to be overwritten. The work involves fixes to migration logic, schema provenance ownership, and preservation of unstamped user settings.

## TL;DR

- 5 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 3 PR(s) closed without merging.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.40`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
