Domain schema: services (sku, name, category, price_from, duration_estimate): service catalog as SKUs; parts_stock (sku, delta, reason, moved_at): parts and consumables movements; jobs (job_no, service_area, status, scheduled_for): jobs as orders with status transitions; job_lines (job_no, sku, qty): services and parts on a job; events (seq, record_type, record_id, kind, at): application-owned history written in the same transaction. Public information: service catalog and pricing from, service areas and hours, licensing and insurance summary. Kept out of scope until handling is reviewed: customer addresses and access notes, payment details. Customer addresses and access instructions are personal data; keep them out until handling is reviewed.
