# NousResearch/hermes-agent · Compression attempt telemetry fields lost during flush

## Open now

- Nothing open on GitHub.

These items address a bug where telemetry fields for compression attempts (such as aux_prompt_tokens and middle_window_tokens) are dropped or nulled out, with fixes aimed at preserving that data across memory flush and commit boundaries.

## 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 #136083. Verify it addresses your case.
- **Recommended:** read PR #136083 (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-136083`. 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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

- #118580: \[Bug\] Compression attempt telemetry never carries seeded fields (aux_prompt_tokens, middle_window_tokens always null)
