LayerFS promises ephemeral workspaces for coding agents in 5 to 20 ms

What the research found

LayerFS is a filesystem for coding agents that mounts ephemeral writable workspaces over shared committed history, with claimed 5 to 20 ms mounts and dedup and conflict handling; it is an early product page with self-reported benchmarks.

Claims and how well the evidence supports them

1. Each agent mounts a writable workspace over shared committed history and commits its changes 99%
2. Measured mounts take 5 to 20 ms per the site 98%
3. Dependencies persist across mounts so installs are not repeated 97%
4. A same-file conflict between agents is refused with a Conflict error 96%
