Time Travel CRDT Skill

"Time is of the essence — but the essence is not time." — Kleppmann & Gentle

CRDTs enable time travel: branch, merge, undo, redo without central coordination. GF(3) coloring for causal consistency.

Overview

Time travel in collaborative systems means:

1. Branching: Diverge from any point in history
2. Merging: Automatically reconcile divergent branches
3. Undo/Redo: Navigate the causal graph
4. Replay: Reconstruct any historical state

This skill connects Diamond Types, Automerge, Eg-walker, and Janus reversible computing.
