find-violations.mjs

#!/usr/bin/env node
// CLI wrapper around src/analyze.js: read flespi API responses from disk, print
// the compliance report as JSON.
//
// Usage:
//   node scripts/find-violations.mjs <parsed.json> [more.json ...] [--gen g1|g2] [--pretty]
//   node scripts/find-violations.mjs public/example.json --pretty
//   node scripts/find-violations.mjs day1.json day2.json day3.json   # same card, merged
//
// Pass several complementary files - successive downloads of the SAME driver card,
// or of the same vehicle unit. They are normalized, merged into one timeline (same
// day from two files -> the richer record is kept), and analysed together. Mixing
// different drivers/vehicles (or a card with a VU) throws an error.
//
// All the logic lives in src/analyze.js - import analyze() from there rather than
// shelling out to this script.
