- #8478: fix: Ctrl+D deletes character under cursor instead of sending EOF

These issues and pull requests address how the CLI handles Ctrl+D, specifically whether it should delete the character under the cursor or exit the session, with proposals to match standard readline/bash/zsh semantics (exit only on empty input).

## TL;DR

- 8 member(s): 1 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 5 PR(s) closed without merging.
- A fix was merged to main in PR #15383. Verify it addresses your case.
- **Recommended:** read PR #15383 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.

## 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.26`: 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.

## Fix status

- Merged to main in PR #15383 (cited above). No release data is tracked. Verify downstream.
- Fix last verified (merged) `2026-04-24`. This confirmation is old and may be out of date (a revert/reopen would not have invalidated it here); re-verify.
