FUNCTIONAL VERIFICATION

Do not only verify that it can run—
verify that every state
responds correctly

Ensure BMS, EMS, PCS, cooling, fire interfaces, and protection logic transition correctly under a controlled state machine across normal, limited, fault, manual-intervention, and recovery scenarios.

Functional validation answers how the system should act — not by repeating performance or life tests.

We have to make every change in the state a basis.
Leave evidence for every fault response

Sixty-four functional scenarios have been completed for final return, SC-47 has exceptionally preserved the full history, and all access to the Cristical/Major functionality has been closed before the system has been technically authorized to enter the final test and FAT phases.

Stage boundary: FUNCTIONAL BEHAVIOR VERIFIED denotes status machine, permission, failure response, heat control, communication/fire-fighting connection and 64 system scenes have been validated. It only authorizes access. Final Testing / FATThis does not mean that FAT itself has passed, nor that PSI, packaging or shipment has been completed.
