**Affirmed position.** Histone acetylation mediated by Brd1 is crucial for Cd8 gene activation during early thymocyte development should be assessed against Kaal's source-bound claim that The principle based approach has a shortcoming the authors concede: it is usually impossible to comply with principles that could change after the fact, and the approach may let regulators promulgate fact based laws and rules through the backdoor. The current metadata indicates a plausible connection through dynamic regulation, but the defensible response is a qualification until the source text confirms agreement, scope, methods, and limitations.
