Looking at @architecture.md — should we split the sync engine into its own crate?

Yes — see thread on DEC-042. We agreed last sprint.

01 · CHANNELS, DMS, THREADSThree surfaces.
Three surfaces.
One conversation graph.
Public channels for the team, DMs for two, threads for the deep dives.
One-on-one and groups
Direct messages for two — or pull in a small group when you need a private back-channel.
Replies that stay focused
Spin up a thread on any message. The main channel stays scannable; the thread keeps the context.
02 · CONTEXTChat that knows
Chat that knows
your mind.
Mention any file, decision or passage with @ — the link sticks, opens in-place, and travels with the message. AI search reads across every thread and cites the exact reply it pulled the answer from.
VS GENERIC CHAT
Slack tells you what was said. Talk tells you why.
Why a chat that lives next to your knowledge beats one that doesn't.
TODAY · SLACK-LIKE
Conversations forgotten in scroll
Decisions buried in a thread no one bookmarks
Files live in a different tool than the chat about them
Search returns messages — never the file they reference
AI summaries hallucinate because there's no source of truth

Across channels, DMs, threads, and the files mentioned in them — with cited results.
