## Open now

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `partially_resolved` · deciding PR(s): `pr-122787`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
- Members outside that structural core may belong to a different underlying problem.
- Pairwise link density `0.29`: 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.

## Closed / duplicate issues

- #6442: TUI stream parser swallows text after literal \`<think>\` tags inside backticks when show_reasoning is false
- #53953: \[Bug\]:Hermes Desktop markdown renderer silently consumes bare \`<word>\` sequences in assistant text (unknown HTML-like tokens treated as unclosed tags)
