Ships the AAP 2022 phototherapy/exchange nomograms, the Bhutani 1999
risk zones, and the Fenton 2013 preterm weight-for-GA chart as real
React calculators. These were the high-risk "table-driven" ports the
migration checkpoint flagged as needing captured vectors before
landing — the whole vector-capture workflow now exists and can be
reused for BP / BMI / growth-beyond-Fenton next.
Workflow, so future calculator ports have a template:
scripts/capture-calc-vectors.js
Standalone Node script. Data tables + math inlined VERBATIM from
public/js/calculators.js (no rewriting, no reformatting). Picks 83
carefully chosen test cases — edge-of-domain, table-key-exact,
interpolated-between-keys, and clinical-decision-boundary values —
and emits e2e/fixtures/calc-vectors.json with
{ inputs, output } pairs produced by the authoritative math.
e2e/fixtures/calc-vectors.json
12 Bhutani cases, 58 AAP 2022 cases, 13 Fenton cases. Re-run
capture-calc-vectors.js whenever the vanilla file changes.
shared/clinical/bilirubin.ts
• 17 HourTable constants ported byte-for-byte from calculators.js
lines 1489-1512: photo 35w/36w/37w/38w/39w/40+ (low risk) +
35w/36w/37w/38+ (medium risk), same 8 for exchange.
• Bhutani zones (p95/p75/p40) from lines 1644-1651.
• interpolateThreshold helper (lines 1514-1525).
• classifyBhutani + classifyAapBili functions mirror the vanilla
click-handler logic.
shared/clinical/fenton.ts
• 15-week × 2-sex LMS table from lines 1168-1183 preserved entry-
for-entry.
• interpolateLMS + calcZ + zToPercentile (Abramowitz & Stegun
normal CDF, lines 2299-2326) ported byte-for-byte.
• fentonWeightForAge returns { L, M, S, z, percentile };
classifySizeForAge labels SGA/<10 / AGA / LGA/>90.
shared/clinical/bilirubin.test.ts + fenton.test.ts
Vitest suites that import e2e/fixtures/calc-vectors.json and assert
classifyBhutani / classifyAapBili / fentonWeightForAge match
every captured vector to 10 decimal places for threshold values
and 6 decimals for the Fenton M (grams, so 6 is >= 1e-3 g).
All 102 tests pass locally (19 prior + 70 bili + 13 Fenton).
client/src/pages/Calculators.tsx
• BiliPanel with AAP 2022 / Bhutani mode switch, GA + risk-factor
dropdowns, color-coded status / zone badges, both threshold
pairs surfaced in the result grid.
• GrowthPanel runs Fenton with sex + GA + weight inputs, emits
Z-score, percentile, L/M/S reference, and SGA/AGA/LGA label.
• PILLS flags bili + growth as ported: true; ActivePanel routes to
the new components. BP / BMI / vitals / resus / equipment
remain legacy-linked until their own vectors land.
e2e/tests/calculators-react.spec.js
Three new parity tests covering above-phototherapy/above-exchange
transitions (38w 72h TSB 20 → phototherapy; TSB 26 → exchange),
Bhutani high-risk classification at 36h TSB 13, and Fenton 32w
male 1795g landing exactly at 50th percentile AGA.
Backend tsc + client tsc + vite build + vitest (102/102) all green.
Bundle 619 kB / 178 kB gz (+10 kB for the bili tables).
