Evidence
The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact two-author 1975 invited tutorial paper and the principles it states. Earlier individual suggestions acknowledged in the paper, Multics implementations, later security taxonomies and modern secure-development practice remain separate.
