core/rollup.py implements the locked truth table: worst gradeable line wins;
a Plan Type Needed line caps the patient at Action Needed; non-gradeable
lines are displayed but never touch the light; no-graded-lines patients carry
None (no label invented). /api/upload gains additive patients[] (one entry
per patient, nested device lines with doc checklists, citations, timing
flags, dedup display fields) and patient_stats (counts patients, not rows).
Flat records payload untouched until P6. Independent audit: SHIP; its LOW
findings fixed (date coercion on timing keys, empty-rollup guard, severity
divergence documented). 151 tests green.
