NervesGate.Indicators (nerves_gate v0.1.0)

Copy Markdown

Three status LEDs and fixed, release-only button gestures.

identify/1 overrides the LEDs for five seconds, then resumes current status. status/1 is read-only; observe/1 subscribes the caller to change hints. Recovery runs in one bounded worker and is never automatically retried.
