Core position

Mobility intelligence must be:

Modular

Replaceable

Diagnosable

Field-serviceable

Never:

Proprietary black box

Cloud-dependent

Firmware-locked

Architectural principle:

Control intelligence should be layered:

Signal layer

Control layer

Power layer

Each layer independently testable.
Each layer replaceable.

Engineering requirement:

A trained technician —  not a factory specialist — must be able to:

• Identify failure
• Replace module
• Restore function
• Verify stability

The deeper design constraint:

Stability must not depend on secrecy.
It must depend on architecture.

Intelligence should fail gracefully — not catastrophically.
