Why Firmware Ownership Stays Separate from the Manufacturer

Hardware development and firmware product logic have different long-term ownership requirements.

The lab result behind Why Firmware Ownership Stays Separate from the Manufacturer changed the implementation more than the first hypothesis did. The manufacturer can own PCB, mechanical, acoustic, RF and factory-test work without becoming the owner of LOUP application firmware.

Keeping firmware source, releases and OTA authority with LOUP preserves the ability to change backend, security policy, UX and telephony behavior independently of the factory. It also prevents production programming from becoming the only place where a product release can be reproduced.

Reversibility stayed part of the experiment: preserve the previous artifact, make the change, then prove the new path before promoting it. Evidence marker: firmware-ownership.

Supplier boundaries should match strategic ownership. Manufacturing access to firmware artifacts is not the same thing as ownership of firmware source and release policy. Preserving that distinction is what lets the project increase complexity without losing the ability to explain a regression.
