# NousResearch/hermes-agent · clock step tolerance fixes for session liveness checks

## Open now

- 1 issue, 1 PR open on GitHub.
- #105714: \`active_sessions._pid_alive\` still compares \`create_time\` with a 1 ms tolerance — a live session's lease is pruned after any clock step (the third site from #62505)
- PR #105720: fix(cli): keep live session leases across clock steps

These items address cases where wall-clock steps cause live sessions to be incorrectly pruned, by widening or removing fragile create_time comparisons in PID liveness and CLI lease logic. A remaining site with only 1 ms tolerance is flagged as still vulnerable.

## TL;DR

- 3 member(s): 1 open issue(s), 0 closed issue(s), 1 open PR(s), 0 merged PR(s), 1 PR(s) closed without merging.

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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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