description	A final verification step to ensure the JSON output meets all structural and constraint requirements before delivery.

1. Day Count Verification: Ensure the plan array contains exactly 7 objects representing Day 1 to Day 7.
2. Attraction Field Validation:
   • Iterate through every day object.
   • Verify that the attraction string is not empty ("").
   • Verify that the attraction string is not a null-placeholder ("-").
   • Confirm the trailing semicolon format.
3. Constraint Check:
   • Confirm transportation never mentions "flight" or "plane".
   • Confirm accommodation is sourced from the database and is pet-friendly.
   • Confirm data_sources lists all files accessed (e.g., distance matrix, restaurant csv, etc.).
4. City Consistency: Ensure that if the current_city is "from A to B", the restaurants and attractions for that day are located in A, B, or a city on the path between them.
5. Budget Check: Sum the estimated costs of restaurants and accommodations (if price data is available in the CSV) to ensure the total is within the $5,100 limit.
