  Smart Tile Serving Test
═══════════════════════════════════════════════════════════════

Test Cases:

Test 1: Exact tile that exists
  Request: z=4, x=2, y=15
  URL: https://tile.map.one/tiles.php?user_id=1&name=20251012T053349Z-ca94635b&z=4&x=2&y=15&token=tst_b255b9dc7fce5f299cba339c5c611e2ffe7080aa4855384b4ddd4968272a
  Expected: ✅ Exact tile served

Test 2: Another exact tile that exists
  Request: z=7, x=12, y=37
  URL: https://tile.map.one/tiles.php?user_id=1&name=20251012T053349Z-ca94635b&z=7&x=12&y=37&token=tst_b255b9dc7fce5f299cba339c5c611e2ffe7080aa4855384b4ddd4968272a
  Expected: ✅ Exact tile served

Test 3: Overzoom: z=10 → should serve z=7 tile at adjusted coords
  Request: z=10, x=48, y=148
  URL: https://tile.map.one/tiles.php?user_id=1&name=20251012T053349Z-ca94635b&z=10&x=48&y=148&token=tst_b255b9dc7fce5f299cba339c5c611e2ffe7080aa4855384b4ddd4968272a
  Expected: ✅ Tile served at lower zoom (z=7)

Test 4: Under min zoom: z=1 → should serve z=4 tile
  Request: z=1, x=0, y=0
  URL: https://tile.map.one/tiles.php?user_id=1&name=20251012T053349Z-ca94635b&z=1&x=0&y=0&token=tst_b255b9dc7fce5f299cba339c5c611e2ffe7080aa4855384b4ddd4968272a
  Expected: ✅ Tile served at higher zoom (z=4)

Test 5: Different location: should return 404
  Request: z=8, x=232, y=148
  URL: https://tile.map.one/tiles.php?user_id=1&name=20251012T053349Z-ca94635b&z=8&x=232&y=148&token=tst_b255b9dc7fce5f299cba339c5c611e2ffe7080aa4855384b4ddd4968272a
  Expected: ❌ Tile not found

How to Test:
───────────────────────────────────────────────────────────────

1. Enable debug mode:
   export PMTILES_DEBUG=1

2. Test a case:
   curl 'https://tile.map.one/tiles.php?user_id=1&name=20251012T053349Z-ca94635b&z=4&x=2&y=15&token=tst_b255b9dc7fce5f299cba339c5c611e2ffe7080aa4855384b4ddd4968272a'

3. Check Apache error log for detailed debug output:
   tail -f /var/log/apache2/error.log | grep PMTILES

4. Clear cache if needed:
   php clear_cache_and_debug.php

  Key Features:
═══════════════════════════════════════════════════════════════

✓ Overzoom: Requests above max zoom serve tiles at max zoom
✓ Parent fallback: Missing tiles try parent tiles (5 levels up)
✓ Geographic accuracy: Only serves tiles from the same area
✓ 404 for missing areas: Returns 'Tile not found' when appropriate
