Separate real bugs from style. Rank issues by severity, point at the root cause rather than the symptom, and suggest a concrete fix — specific and kind.

const NY_OFFSET = '-05:00'; // New York is UTC-5 function nineAmUtc(dateStr) {  // dateStr like '2026-01-15'  const iso = `${dateStr}T09:00:00${NY_OFFSET}`;  return new Date(iso).toISOString();} function scheduleSeries(dates) {  return dates.map((d) => ({    date: d,    startUtc: nineAmUtc(d),  }));}
