- #43394: fix(memory): _resolve_entity uses LIKE for exact match — wildcard and case-sensitivity bugs create duplicate entities
- PR #40746: fix(memory): treat entity names as literals in holographic resolution

All members address the same bug: the \`_resolve_entity\` function used SQL \`LIKE\` instead of exact equality (\`=\`) when matching entity names, causing wildcard characters and case-sensitivity issues to produce duplicate entities.

## TL;DR

- 5 member(s): 1 open issue(s), 0 closed issue(s), 1 open PR(s), 0 merged PR(s), 3 PR(s) closed without merging.

## 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.40`: 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.
