Teamz storyboards enterprise collaboration: channels/DMs, Kanban, GitHub-style activity, calendar, goals, presence — the day-to-day team surface. TEAMZ1-CORE.html is the UI shell; COFFEE-TEAMZ/PRO-STACK.md describes the recommended Pro backend.
Teamz Pro is meant to be server-authoritative: durable messages and history, not ad-hoc P2P as the system of record. The stack sketch: coffee-server (Express) + WebSockets (or SSE) for realtime + SQLite or Postgres + org auth for members + Keyman for operator/API boundaries + vault for tokens (e.g. GitHub) kept off the browser.
Nostr / PeerJS are documented as optional edges, not the authoritative store for private org collab — that clarity is part of the arc’s team-management honesty.
That order is how you de-risk team features: identity and data model before flashy realtime.
