Add GET /api/activity/patient/:fileNumber (every audited change on one chart,
newest first, readable by any clinic member) and surface it as a Record
history timeline in the patient detail sheet. Add a Download summary action
that builds a clean, printable one-page clinical summary in the browser
(Save as PDF) — no PDF dependency, nothing leaves the server.
