A bug where ContextVar-based skill_view marks are lost when crossing tool-call worker threads, causing the curator's read-before-write guard to always refuse patches or edits to existing skills. The members cover the bug report and several fix attempts addressing this thread-context propagation issue.

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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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

- #94324: \[Bug\] Background curator read-before-write guard can never pass: skill_view marks (ContextVar) are lost across tool-call worker threads, so every patch/edit of an existing skill is refused
