 - Agents/subagents: keep collect-mode announce queues batching unresolved-origin items with compatible same-route messages and resume collection after a true cross-channel drain when a later compatible batch remains. Fixes #83577.
 - Skills: refresh existing session skill snapshots when watched skill roots change, so changed extra skill directories take effect without starting a new session. Fixes #83782. (#83800) Thanks @hclsys.
 - Providers/Anthropic: preserve native image input for current Claude model rows when stale local catalog data marks them text-only. (#83756) Thanks @TurboTheTurtle.
-- Providers/DeepSeek: normalize MCP tool schemas with `anyOf`/`oneOf` unions before sending them to DeepSeek, preventing union-shaped parameters from being rejected. (#83766) Thanks @TurboTheTurtle.
+- Providers/DeepSeek: normalize MCP tool schemas with `anyOf`/`oneOf` unions before normal and compaction requests reach DeepSeek, preventing union-shaped parameters from being rejected. (#83766) Thanks @TurboTheTurtle.
 - Control UI: render live tool progress from session-scoped `session.tool` Gateway events so externally started runs show their tool cards in the active session. (#83734) Thanks @TurboTheTurtle.
 - Outbound: resolve send-capable channel plugins from the active runtime registry when the pinned startup registry only has setup metadata. (#83733) Thanks @TurboTheTurtle.
 - Control UI: keep the chat delete confirmation popover clamped inside the visible viewport on small screens. (#83804) Thanks @ThiagoCAltoe.
