The previous tables grouped all ≥38-week infants into one table (using
38w values) and 36-37 into another. AAP 2022 actually has separate
phototherapy curves per completed week for 35, 36, 37, 38, 39, 40+.
Worst real-world impact: a 40-week infant at 72h of life got the 38w
threshold (18.8 mg/dL) instead of the correct 40w threshold
(19.8 mg/dL) — a 1.0 mg/dL error at exactly the clinical decision point.
Borderline infants could be started on phototherapy unnecessarily, or
the reverse (miss a true threshold) depending on the direction.
Replaced the block with 18 distinct per-week tables extracted directly
from peditools.org/bili2022 API:
- Phototherapy no-risk: 35, 36, 37, 38, 39, 40+ (all differ)
- Phototherapy with-risk: 35, 36, 37, 38+ (38-41 identical)
- Exchange (both risk states): 35, 36, 37, 38+ (38-41 identical)
Selection logic updated to map gaNum → correct table. HTML dropdown
label clarified to "completed weeks" with a one-line note that days
don't change the curve per AAP 2022.
Validation: exhaustive roundtrip — 7 GA weeks × 85 hours × 2 risk
profiles = 1190 cases, all match peditools within 0.01 mg/dL (zero
mismatches). See commit message footer.
