# NousResearch/hermes-agent · Agent background review transcript isolation fixes

## Open now

- Nothing open on GitHub.

A cluster of bug fixes addressing how the agent handles transcript and wire-byte state during background review forks, preventing payload divergence that degraded cache prefix hit rates after agent close or review cycles.

## TL;DR

- 4 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 2 PR(s) closed without merging.
- A fix was merged to main in PR #101074. Verify it addresses your case.
- **Recommended:** read PR #101074 (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-101074`. 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.50`: 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

- #100795: \[Bug\]: State-rebuild payload divergence — after agent close / background review, the next user turn's API request no longer matches the cached prefix (0–85% hit for one shot)
