- services/field: Einsatz-Sessions (Anfahrt/Arbeit/Pause als TimeEntry-Segmente,
  eine aktive Session je User+Auftrag), Zeitkorrektur mit Recht + Grund + Audit,
  Checkliste, Material (Abweichung nur mit Begründung, Zusatzmaterial), Notizen,
  Fotos, Sprachnotizen (ohne Transkriptions-Processor Status disabled), Uploads
  (idempotent je Mandant), autorisierte Dokument-Auslieferung, Lesemodelle + Bundle
- services/sync: applyOperations mit Idempotenz, baseVersion-Konfliktprüfung,
  Registry für Ops anderer Lanes, lane-lokaler requireApiContext
- /api/v1/sync, /api/v1/uploads, /api/v1/field/bundle, /api/v1/field/documents/[id]
- lib/sync/ops.ts (Zod-Payloads je opType), lib/field/material-rules.ts
- Stubs mit Vertragssignatur: transitionWorkOrder (L2), storeFile (§4.3),
  getSiteHistory (L1)
- Processor image-derivatives + Registrierung, Audit-Entity-Labels
- Tests: test-einsatz-field (48 Prüfungen), test-einsatz-sync (38 Prüfungen)
