## Summary

LayerFS is a filesystem that lets AI coding agents mount a writable workspace over a shared, committed history. Each agent runs on its own computer, commits every file‑tool call as an atomic Store operation, and discards the workspace when done. The design enables massive parallelism: six core agents and four supporting agents on different machines share one serverless Store.

The system records every step as a checkpoint, with commits that are append‑only and content‑addressed. A fork copies only metadata, so ten copies compress into 0.31 of the original size, with a deduplication ratio of 1.05. Installation takes ~5 min, while mounting takes 0.05 s. Conflict rules prevent same‑file clashes, and a .lww file lets the newest edit win.

## Key points

- Agents spend ~80% thinking and ~10% in Bash, with each tool call becoming a commit
- Ten copies compress into 0.31, with a deduplication ratio of 1.05
- ~5 min install versus 0.05 s mount, enabling massive parallelism

## Why it matters

Provides AI developers a low‑cost, fast, and conflict‑free storage layer, scaling multi‑agent workflows without a database server.
