  "headline": "The 2026-08-20 release adds two resource types. InsurancePlan arrives usable: 233 health plans, every one naming an owning organization, across 27 payers. HealthcareService arrives empty: 54,445 resources of which 0.5% name a location, 1 name a provider, and none carry a service name, type or specialty. It is a network-membership join, not a description of a service.",

  "notes": "Measured by streaming the release's own NDJSON rather than through BigQuery, because there are no tables for these types yet and a release should be characterizable the day it lands. HealthcareService carries active, extension, id, location, meta, providedBy, resourceType and nothing else; the descriptive fields that would make it a service record (name, type, specialty, category, telecom, comment, availableTime, serviceProvisionCode) are absent from every resource. The registered prior, that a new resource carries identity before it carries detail, holds for HealthcareService and is rejected for InsurancePlan, which is complete enough to use on arrival. One caveat on InsurancePlan: `type` is free text and not coded, and the same product appears under several spellings (Medicare Advantage PPO Plan, CSNP-COPD, mediadv, MAPD, CSNP, Qualified Health Plan), so grouping plans by type requires normalising strings rather than reading a code. Reproduce with analysis/h55_new_resource_types.py.",
