Core primitives - Reflex

rfx organizes its API into focused package surfaces:

Surface	Purpose
`rfx.robot`	Robot contract, config, discovery, and hardware-facing abstractions
`rfx.sim`	Simulation and mock execution
`rfx.collection`	Dataset recording and collection contracts
`rfx.runtime`	Lifecycle, health, CLI, operational helpers
`rfx.teleop`	Teleoperation and high-rate recording built on the same primitives

Intent

Keep the middleware core small and explicit.
Treat simulation as a primitive, not an afterthought.
Treat collection as a primitive, not a script on the side.
Keep robot adapters separate from framework identity.
Let workflow helpers compose on top of the primitives instead of defining them.

Usage

import rfx

robot = rfx.MockRobot(state_dim=12, action_dim=6)
obs = robot.observe()

Access package surfaces directly:

import rfx

rfx.robot       # Robot protocol, config, discovery
rfx.sim         # Simulation and mock backends
rfx.collection  # Collection and dataset APIs
rfx.runtime     # Runtime and operational helpers
rfx.teleop      # Teleop on top of the same robot/runtime contracts
