Skepticism ("is this even real?") is the top objection. The data IS accurate
(verified our subscribers' NPIs match the official CMS Revalidation Due Date List
exactly), so this is a credibility-presentation fix:
1. Email: replace the plain detail row with an "Official record - CMS Medicare
Revalidation Due Date List" card (NPI, legal name, due date, days overdue)
plus a "Verify on CMS.gov" button. Clearly labeled as our presentation of
public CMS data, not a CMS screenshot (no impersonation).
2. API: npi/lookup now pulls the revalidation due date LIVE from the public CMS
dataset (data.cms.gov) instead of the empty local table, and returns a
revalidation{ due_date, source, cms_legal_name, verify_url } proof object.
3. Tool: /tools/npi-compliance-check shows a live "official record" card with a
self-verify link when CMS returns a due date.
Builder now stores reval_due_date/days_overdue as separate attribs for the card
(existing 194 subscribers backfilled from their detail string).
