Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Stoplight-shaped notifier whose only job is to translate the upstream ‘notifier.notify(light, from_color, to_color, error)` callback into a StandardCircuit Rails event.

Stoplight calls notifiers on every color transition (GREEN<->RED, RED->YELLOW for half-open recovery). We map each transition to a stable event name and forward a uniform payload to whichever event bus is live.

This is the single Stoplight notifier StandardCircuit registers — Logger, Sentry, and Metrics are now subscribers, not direct notifiers.
