- #18426: patch tool can create duplicate content loops when used repeatedly
- PR #56570: fix(tools): patch idempotency guard prevents duplicate-content loops on re-edit (#18426)

The members concern the patch tool producing duplicated content when edits are applied repeatedly, along with two pull request titles describing guards (idempotency and replay protection for JSON value patches) intended to address this. The titles alone do not show whether those changes are complete, merged, or effective.

## 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.
- 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.67`: 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.
