Elaborates framework PRD FR-8/9/10 for a hosted, multi-tenant service:
stakeholders, which Stage 0 guarantees (WP-0002) carry over unchanged

onto which task (T03-T08), functional/non-functional requirements, and
an API surface sketch. Flags that no current task owns hosting the
Breach/Compliance Record component added by License V1C1 SS7.4.
