Lumo Labels

Lumo Labels is a Dockerized Proton Mail auto-labeler. It polls unread inbox mail, classifies each message with the local Lumo model, and applies the matching Proton label.

The runtime is a single Docker container managed by supervisord. It runs the Go API server, the polling daemon, and the local Lumo API V2 process together.

What It Does

For each unread inbox message, the app:

1. Fetches the message from Proton Mail.

2. Redacts configured sensitive content.

3. Builds a classification prompt using GARDRAIL.md, TUNING.md, sender, subject, body, and recent applied decisions.

4. Sends the prompt to Lumo.

5. Parses the response against the allowed label list.

6. Applies the label in Proton Mail when a match is found.

7. Persists checkpoints and decisions so messages are not reprocessed unnecessarily.
