Defined in:

Overview

Rack middleware that:

1. Builds an Omnitrack::Context from the incoming request
2. Makes it available thread-locally as Omnitrack::Context.current
3. Clears it after the response (prevents cross-request data leakage)

Auto-inserted by the Railtie; can also be added manually:

config.middleware.use Omnitrack::Middleware::RequestTracker
