# NousResearch/hermes-agent · YAML config scalar mutation and data loss fixes

## Open now

- Nothing open on GitHub.

These issues and pull requests address bugs in config.yaml handling where ruamel-yaml re-folding silently mutated long quoted scalars, and where transient read errors could wipe config contents. The work focuses on preserving stored values accurately during config read and write operations.

## 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.
- A fix was merged to main in PR #120343. Verify it addresses your case.
- **Recommended:** read PR #120343 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `resolved` · deciding PR(s): `pr-120343`. 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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.

## Closed / duplicate issues

- #119844: \[Bug\]: config saves silently insert spaces into long double-quoted scalars (ruamel re-folding mutates stored values)
