# NousResearch/hermes-agent · Stale close stamps blocking session compression fix

## Open now

- Nothing open on GitHub.

These issues and PRs concern a bug where a stale explicit-close timestamp on an active session causes compression to permanently no-op with no recovery path. The work addresses detecting and healing such stale end stamps so compression can proceed normally.

## TL;DR

## 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.50`: 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

- #106459: Pain cluster: over-limit sessions become permanently uncompressible — compression result is discarded when the session row is marked ended, /compress no-ops, no recovery path
