BDN-TEP-01: Exploratory Transfer-Extension Protocol and Multi-Constant Candidate Register

This record is a supplementary exploratory priority note linked to the C106/v1.6 BDN-137 record. It records a pre-validation BDN-like transfer-extension protocol and candidate register for possible future multi-constant readouts. The record is intended to preserve priority and traceability for the transfer-extension programme only. It does not claim that the listed constants have already been physically derived, validated, or incorporated into the frozen C106 BDN-137 model. The C106/v1.6 no-retuning boundary remains unchanged. This record preserves priority and traceability for the BDN-TEP-01 exploratory transfer-extension programme only. It does not modify, retune, validate, or replace the frozen C106/v1.6 BDN-137 construction.
