Khalid Abdi 929bec8f31 feat: AI-added records save with placeholders + "Added by AI" provenance
Stop blocking AI imports/proposals on missing non-critical fields. Records
the chat agent drafts now save with safe placeholders, auto-generated file
numbers, and a source="ai" marker that surfaces an "Added by AI" badge so a
clinician can review/edit them later.

Backend:
- add `source` (manual|ai) column to patients/appointments/prescriptions
  (migration 0014) + canonical types, services, validation schemas
- relax patient/appointment validation: empty file number allowed, demographic
  + type/provider/initials fall back to placeholders (initials derived from name)
- patients.generateFileNumber() auto-assigns an MRN when one is missing
- proposeAppointment accepts a name when no file number resolves; AI commits +
  /api/ai/import stamp source="ai"

Frontend:
- `source` on Appointment/Patient/Prescription types; AI commits send source="ai"
- reusable <AiBadge> shown on the Patients table/detail and prescriptions list

Animation

Defaults

Most cartesian charts default to ~1100ms enter animation. Bar charts often use staggered reveals (~1.2s total) with easing cubic-bezier(0.85, 0, 0.15, 1).

Replay enter animations

Pass a changing revealSignature (or remount the chart with a new key) to replay mount animations after prop changes.

Correct

const [replayKey, setReplayKey] = useState(0);

<LineChart key={replayKey} data={data} revealSignature={String(replayKey)}>
  {/* ... */}
</LineChart>

<button type="button" onClick={() => setReplayKey((k) => k + 1)}>
  Replay
</button>

Live charts

  • LiveLineChart runs its own animation loop — use paused to freeze updates for debugging.
  • Avoid nesting heavy state updates inside the rAF path; pass stable props where possible.

Reduced motion

Respect prefers-reduced-motion when adding custom animation wrappers around charts. Bklit charts handle reduced motion internally for enter transitions.

Performance

  • Prefer CSS/SVG-friendly props over re-creating large data arrays every frame.
  • For streaming data, append points and trim the window instead of replacing the full array when possible.
