Generate a full clinical trial protocol document (ICH E6(R2)/FDA-style) for a drug or medical device, including background, objectives/endpoints, study design, population/eligibility, intervention details, assessment schedule, statistical analysis plan with sample-size justification, safety monitoring, and regulatory/ethical sections.

Use when the user says "/fable-domain SECTOR", "make a skill for DOMAIN", "add a domain to the fable method", or "give a lesser model Fable's workflow for DOMAIN". The bundle is the deliverable; a workflow without its flowchart, sources, and trap is not done.
