# NousResearch/hermes-agent · Gateway session.replay_gap handling when clients fall behind

## Open now

- Nothing open on GitHub.

These members appear to concern clients that fall behind or reconnect and how \`session.replay_gap\` is handled by the gateway and CLI. One reports the CLI hanging on later turns after a replay gap was treated as a turn failure, and another proposes re-attaching instead of ending the turn in error; the outcome is not established by the titles.

## TL;DR

## 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.67`: 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.
