- #53362: TUI Python process pegs CPU at 99% and becomes unresponsive — /stop, Ctrl+C, and keyboard input all ignored
- PR #53381: fix: replace SIG_IGN for SIGINT with two-stage handler in TUI gateway

The members center on a TUI Python process that reportedly pegs CPU and ignores /stop, Ctrl+C, and keyboard input. Two related pull requests propose changes to signal handling in the TUI gateway, including a two-stage SIGINT handler, EOF exit, and SIGKILL escalation.

## TL;DR

- 3 member(s): 1 open issue(s), 0 closed issue(s), 2 open PR(s), 0 merged PR(s), 0 PR(s) closed without merging.

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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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