The user drags a flight ticket (PDF/text/ics/html) onto the chat panel,
or uses the new 📎 button. The doc is text-extracted server-side
(pdftotext for PDFs; images rejected with a clear "no OCR" message),
then the LLM reads it, extracts the confirmed arrival + departure
(date, local time, airport, city) and calls a new deterministic tool,
apply_flight_anchors, which reconfigures the trip:
- re-dates the day window across the booked [arrival, departure] span
(contiguous when the day counts match, evenly spread when they don't)
- records the flights as hard-anchor bookings, replacing placeholders
- shortens the arrival day (start after landing + a real airport→hotel
taxi time) and the departure day (ends exactly at the booked time)
- trims stops that no longer fit and updates the trip title's range
Undo/redo and reload persistence now version the trip's bookings + title
alongside days/stays, so a re-configuration reverts and reloads cleanly.
Server gains POST /parse-doc. Verified E2E (LLM extraction + reconfigure),
idempotency, drag-and-drop, and undo; non-flight agent unaffected.
