An anonymized model of airline, port, document and first-hour failures, with a recovery path instead of copied anecdotes.

Separates 12306 account state, passenger verification, ticket purchase, change/refund and station-gate handling.
Annual calendar readyHoliday impact calendar
Turns official dates into booking, crowd, transport and fallback decisions rather than publishing a date list alone.
Current official baselineDeparture tax-refund tracker
Tracks effective and announced changes across store, customs, airport and refund-payout steps.
