- #132048: \[Bug\]: Relay-managed plain-generator stream close races blocked iterator after interrupt
- PR #132059: fix(relay): drain the off-loop provider read before closing the raw stream
- PR #132064: fix(agent): close an interrupted relay provider stream on its owning thread

These issues and pull requests address race conditions and threading problems that occur when closing relay-managed streams, particularly around interrupted generators and off-loop reads. The work targets multiple close-path seams where blocked iterators or unread data could cause unsafe behavior.

## TL;DR

- 4 member(s): 1 open issue(s), 0 closed issue(s), 2 open PR(s), 0 merged PR(s), 1 PR(s) closed without merging.
- No fix has been merged to main; one or more PRs were attempted (see below).
- **Recommended:** review the prior/competing PR(s) below. A fix was attempted but not merged; your case may extend or revive that work.

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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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