"""
freight/scripts/generate_freight_dataset.py β€” Full-Spectrum Multi-Intent US Freight SFT Dataset Generator.

Trains LoadETA across all 5 operational pillars of commercial trucking:
1. Spot Rate Negotiation & Booking (FMCSA verification, Rate Floor, Equipment, Driver info, Rate Con)
2. Check Calls & In-Transit Tracking (Miles out, MacroPoint ELD link, ETA updates, weather/traffic delays)
3. Accessorials, Detention & Lumpers (Detention >2hrs, BOL in/out timestamps, EFS/Comchek codes, TONU)
4. Billing, POD & Factoring Inquiries (Signed BOL/POD submission, Notice of Assignment, QuickPay status)
5. Equipment, Safety, HOS & Regulatory Q&A (IFTA, 11h/14h clock, 80k GVWR axle limits, Kingpin laws, MC vs DOT)

Strict Speech & TTS Hygiene:
- Digit-by-digit pronunciation for IDs and MC numbers
- Natural spoken phrasing for dollar amounts
- Full state name pronunciation
- No company suffixes (LLC, INC)
- No robotic markdown, bullets, or emojis

Usage:
