Fabric RMT Lane Mapping

How RMT scheduling intent maps to Fabric lanes.

What it covers

Lane mapping translates RMT scheduling intent into canonical Fabric lanes. The RMT record states priority and purpose; Fabric decides execution, telemetry, and backpressure for the current platform.

Public building blocks

• fabric/rmt-lane-mapping.js normalizes lanes and schedules.
• fabric/rmt-lane-mapping.d.ts types resolutions, diagnostics, and mapping.
• fabric/xtend-fabric.js runs the resulting fiber.

Recommended workflow

critical, visible, transition, idle, and diagnostics resolve through defined profiles. An unknown lane yields a diagnostic and documented default, not a new global priority class. Review Scheduling and Lanes before a host introduces custom names.
