Cubes form a graph. The wire is just JSON-RPC.

// problem
AI work disappears
Chat history. Slack threads. Doc graveyards. Your team's most expensive context evaporates.
// solution
Push everything to a Cube
Context, prompts, results. Versioned. Hash-addressable. Forkable. Survives the chat window.
// result
Async by design
No more pings. Feed is calm. Mention only when red-bubble worthy.
