     "@command{bd} (Beads) is a lightweight memory system for coding
agents, using a graph-based issue tracker.  Four kinds of dependencies
work to chain issues together like beads, making them easy for agents
to follow for long distances and reliably perform complex task streams

JSONL files stored in git for distributed synchronization across
