The .eno format

A run is written to a single .eno file. It is a plain, documented file on your own disk — and it is the reason you can walk away from Cloud without losing anything.

What’s inside

One file holds the whole run:

Cases and outputs — every input, and exactly what came back.

Scores — per-case results and the aggregate.

Provenance — the commit, model, and settings used for the run.

Reading a file

Nothing is locked away:

omic show run.eno — inspect a run from the terminal

omic diff a.eno b.eno — compare two runs directly

omic export --json — convert to JSON for your own tooling

Why it matters

The format is the guarantee:

Local by default — runs never leave your machine unless you connect Cloud.

Documented — the spec is public; you can read a file without Omic.

Portable — stop paying and your history is still yours.
