These issues and PRs concern bugs and features around how reasoning or chain-of-thought content (think blocks, Anthropic thinking blocks) is filtered, preserved, and displayed to users on platforms like Telegram during and after streaming. Topics include content leaking, content being silently dropped, and adding configurable collapsible display of reasoning output.

## 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evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.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 `0.15`: 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.
