- `ui/docs/diplomail-ui.md`: new topic doc covering the wire
surface, recipient-by-race-name decision, threading model,
translation toggle, push events, badge, layout, and
accessibility.
- `docs/FUNCTIONAL.md` §11.4 grows a paragraph that records the
UI's per-race threading rule, the absent read-receipt UX, and
the recipient-by-race-name compose path. Mirrored verbatim into
`docs/FUNCTIONAL_ru.md`.
- `ui/PLAN.md` Phase 28 marked done with a "Decisions during
stage" block matching the implementation plan, and the artifact
list updated to the actual file set.
