# NousResearch/hermes-agent · Plugin load race, fork checkpoint, compression fixes

## Open now

- Nothing open on GitHub.

These items address a race condition in plugin loading, incorrect checkpoint requirements for certain fork types, and a telemetry miscategorization of compression outcomes. The fixes span agent, compression, and telemetry components but share a common thread around plugin initialization and checkpoint API errors.

## TL;DR

- 4 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 2 merged PR(s), 1 PR(s) closed without merging.
- A fix was merged to main in PR #133054. Verify it addresses your case.
- **Recommended:** read PR #133054 (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-133032`. 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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.
