Testing cron position tracking...

Scenario 1: position is NULL
  Old code (line 624): currentPosition = (null ?? 1) = 1
  Correct code (line 734): position = (null ?? 0) + 1 = 1
  ❌ BUG: Old code defaults to 1 instead of 0

Scenario 2: position is 0
  Old code (line 624): currentPosition = (0 ?? 1) = 0
  Correct code (line 734): position = (0 ?? 0) + 1 = 1
  ✓ OK: Null coalescing preserves 0

Scenario 3: position is 1
  Old code (line 624): currentPosition = (1 ?? 1) = 1
  Correct code (line 734): position = (1 ?? 0) + 1 = 2
  ✓ Both handle existing values correctly

Scenario 4: Genesis 1:1-5 trace
  Initial state: schedule.position = 0
  Run 1:
    Line 734: position = 0 + 1 = 1 → calculateVerseAtPosition('Genesis 1:1-5', 1)
    VerseApiClient: targetVerse = 1 + (1 - 1) = 1 → Genesis 1:1 ✓
    Line 663: newSchedulePosition = 0 + 1 = 1
    Updated: schedule.position = 1
  Run 2:
    Line 734: position = 1 + 1 = 2 → calculateVerseAtPosition('Genesis 1:1-5', 2)
    VerseApiClient: targetVerse = 1 + (2 - 1) = 2 → Genesis 1:2 ✓
    Line 663: newSchedulePosition = 1 + 1 = 2
    Updated: schedule.position = 2
  Run 3:
    Line 734: position = 2 + 1 = 3 → calculateVerseAtPosition('Genesis 1:1-5', 3)
    VerseApiClient: targetVerse = 1 + (3 - 1) = 3 → Genesis 1:3 ✓
