These issues and pull requests address a pattern where attachment and media downloads across multiple platforms (Matrix, Teams, Google Chat, video) buffer full responses before enforcing size limits. The work involves streaming downloads and applying size caps on actual bytes received rather than after buffering.

- 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evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.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 `0.17`: 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.
