These are Sebastian-authored educational tools, not audit opinions, legal advice, customer outcomes, or standards endorsements. PCAOB material is auditor-facing; NIST frameworks are voluntary; management remains responsible for its own accounting policies, controls, evidence, and technology decisions.
Every worksheet can be completed in the browser, downloaded as a CSV, or printed to a clean PDF. The worked examples are fictional and labeled so a staged scenario cannot be mistaken for customer proof. The Sebastian appendix on each resource states implemented behavior and assigns no future credit to unavailable capabilities.
Named finance authorship and independent customer proof remain separate evidence gates. Until a qualified reviewer and permissioned customer are published, these resources should be judged on their mechanism, primary-source accuracy, and usefulness—not on implied authority.
