defaults. Rescope Trust Service work to offline schemas/fold/fixtures, add
normative core extraction workplan, and split PRD roadmap Phase 4 into
foundation vs hosted service. Sync workplans with State Hub.
Establishes specs/ProductRequirementsDocument.md and
specs/TechnicalSpecificationDocument.md, plus two workplans: prior-art
research for the TargetRevenueSourceLicense draft, and bootstrapping the
Trust Service reference implementation.
