The PDHC synthetic clinical-data generator — reproducible, FHIR-coded cohorts, attributed to real PlanDefinitions and organisations, landed straight into the platform's CDRs.
Sim produces synthetic longitudinal patient data (never real
patients) and pushes it where the platform needs it — patient identities into
ips.pdhc, observations into a CDR. Every value is tagged synthetic
and coded against a plan.pdhc Concept, so downstream services treat
it exactly like production data. It runs as a local operator CLI
(python -m sim …); there is no public endpoint.
Drive MITRE Synthea straight from a plan.pdhc
PlanDefinition: a cohort whose observations are exactly that plan's
concepts, on its cadence, over a chosen time window.

--purge-source completes the move (only after a
verified-complete copy).

lands Patients in ips.pdhc; --push-observations
adds Shape B (mapped Observations into a CDR).
