## Open now

- #8041: Bug: ProcessSession.env_ref holds strong reference, prevents GC of environment objects for 30 minutes
- PR #8072: fix: use weakref for ProcessSession.env_ref to prevent GC leak
- PR #8075: fix: use weakref for ProcessSession.env_ref to allow environment GC

Most members address a memory management issue where ProcessSession.env_ref holds a strong reference blocking garbage collection of environment objects, with weakref corrections proposed. One unrelated member adds detection of SQLite/JSONL divergence following incomplete rewrites.

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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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