Dynamic Itinerary Stitching and CalDAV Transit Sync
Coordinating multi-leg travel schedules across disparate booking confirmations requires deterministic calendar synchronization. CalDAV protocols provide standardized event streaming without proprietary vendor lock-in.
Itinerary Invariants
- RFC 5545 Compliance: Transit legs and hotel waypoints generate standard VEVENT components with embedded GPS coordinates.
- Declarative Booking Sidecars: Confirmation PDFs pair with JSON metadata sidecars capturing booking references and cancellation policies.
- Automated Timeline Merging: The Wayfinder engine resolves overlapping transit windows and flags impossible connection intervals.
Deterministic calendar synchronization keeps expedition timelines transparent and resilient to change.
