Cross-chain control and correlation matrix

Run python3 verify_control_matrix_offline.py to check the curated84-authorization/6-key matrix, five chain-pair joins, selectedCar5keys/77addresses and the new mass-mint counterparty comparison. This does not rerun the previously completed cryptographic signature recoveries.

In the retained investigation workspace, build_control_matrix.py reconstructs these outputs from the exact sources recorded by SHA256 in SOURCE-PROVENANCE.json. It performs no network call and rewrites only this control directory. Its full raw/earlier proof dependencies are separately retained; this selection is not a standalone cryptographic84-signature replay.

Fresh state, history and existing signature proof scopes remain distinct. Same address/shared factory/unsolicited token receipt do not establish shared control. No new runtime-positive same-address account outside Polygon5a was found in the20 complete current-state networks; Blast and Plasma gaps remain gaps. Full third-party deployment documentation bodies are not selected.
