  Findings
  --------
  [WARNING] cue  2 (line 5)  overlap
            Overlaps the previous cue by 300 ms.
  [ERROR  ] cue  3 (line 9)  numbering

  [WARNING] cue  3 (line 9)  short_duration
            Displayed for 0.30 s — may be too brief to read (rule: ≥ 0.83 s).
  [WARNING] cue  3 (line 9)  reading_speed
            Reading speed 230.0 characters/second exceeds the 20 cps rule.
  [WARNING] cue  3 (line 9)  line_length
            Line has 69 characters (rule: ≤ 42).
  [ERROR  ] cue  4 (line 13)  numbering
            Cue number 5 is out of sequence (expected 4).
  [ERROR  ] cue  4 (line 13)  end_before_start
            End time must be later than start time (00:00:09,000 → 00:00:08,000).
  [ERROR  ] cue  5 (line 17)  numbering
            Cue number 6 is out of sequence (expected 5).
  [ERROR  ] cue  5 (line 17)  end_syntax
            End time "00:00:12.500" is not a valid SRT timestamp (HH:MM:SS,mmm).

  Scope
  -----
  Automated checks cover file structure, timestamp syntax, numbering, order,
  overlaps, readability rules and encoding. They do NOT verify that the text
  matches the spoken audio; that requires review against the source media.
