# NousResearch/hermes-agent · macOS deleted-WAL holder detection via libproc

## Open now

- Nothing open on GitHub.

These issues and PRs concern a bug where the check for processes holding a deleted WAL sidecar file was Linux-only and silently did nothing on macOS, allowing a gateway restart to create a replacement WAL under a live writer. The work involves implementing the holder enumeration on macOS using libproc.

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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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