Two-tier service model the marketplace is priced and searched on. Admin catalog skeleton (categories + EAV option groups/values, addable as data not migrations; NULL category = cross-category) and the nurse pricing layer (nurse_service_variants — the atomic bookable unit: category + one value per required dimension at the nurse's own IRR price and price unit). - New `catalog` schema via one additive migration; Price BIGINT (no floats), on the wire as a string of digits; total = price + unit + session_count. - Duplicate-listing guard: deterministic option_set_hash + filtered UNIQUE(nurse_id, service_category_id, option_set_hash) WHERE deleted_at IS NULL + friendly 409 pre-check. One value per dimension; required groups (incl. cross-category) enforced; deactivate, never delete. - Public catalog browse cached behind a CatalogCache generation token, invalidated on any admin write. IVariantSnapshotSerializer shipped for b8. - Contract (catalog.md) + handoff + report published; swagger refreshed. 122 tests green; zero new build warnings.
