Risks
Three things most likely to hurt us.
Migrating live billing
High likelihoodMitigation: dual-run old and new billing for one full cycle in October; no clinic moves until its shadow invoice matches to the cent.
Proration edge cases
Medium likelihoodMitigation: Ines writes the twelve known cases as tests in week two, before any code. Unknown cases get a manual override path.
Sales promising early
Medium likelihoodMitigation: one approved sentence for prospects, owned by Jonah, and no dates given to customers before Oct 23.
