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).
Replaces the legacy-viewer fallback for three of the fifteen Bedside
sub-modules with real React implementations. Weight-based dosing now
runs locally for the most time-critical emergencies — the other 12
modules (neonatal, airway, respiratory, ventilation, sepsis, sedation,
agitation, antiemetics, antimicrobials, burns, toxicology, trauma)
still fall through to LegacyPanel.
shared/clinical/calculators.ts
New formatDose(weightKg, perKg, max?, unit = 'mg') helper that
mirrors the vanilla S.dStr exactly — same rounding, same cap rule,
same label format. Returns { value, unit, capped, perKg, max,
label } so consumers can render rich UI without re-parsing a HTML
string. Pure function; unit tests in the existing vitest suite
still pass.
client/src/pages/BedsidePanels.tsx (new)
Three panels keyed to the Bedside pill id:
• AnaphylaxisPanel — STEP 1 epi IM callout + full 9-row dosing
table (fluids, diphenhydramine, ranitidine, dex, methylpred,
refractory epi gtt, glucagon). Drug per-kg + max values ported
verbatim from ANAPH_FALLBACK in the vanilla module.
• CardiacPanel — PALS dosing with 6 sub-views (general,
asystole/PEA, bradycardia, SVT, VF/pulseless VT, stable VT).
Every drug row carries the same mg/kg + max values as the
vanilla cardiac.js (epi, amio, lido, atropine, adenosine ×2,
bicarb, CaCl/CaGluc, Mg, D10, defib energies). Concentration
disclaimer + AHA citation preserved.
• SeizurePanel — full status-epilepticus timeline (0 min →
40 min refractory) with the vanilla SEIZURE_FALLBACK drug
table (loraz / midaz / diaz for benzo; levetiracetam /
fosphenytoin / valproate / phenobarb for 2nd-line; midaz
pentobarb propofol ketamine infusions for refractory). Key
points + citation preserved.
REAL_BEDSIDE_PANELS set + renderBedsideRealPanel(pillId) export so
Bedside.tsx can dispatch by id without import sprawl.
client/src/pages/Bedside.tsx
When the active pill is in REAL_BEDSIDE_PANELS, render the real
panel; otherwise fall back to LegacyPanel. No other changes — the
sub-nav, age→weight estimator, and 12 legacy-linked modules stay
exactly as they were.
e2e/tests/bedside-react.spec.js
Three new parity tests (in addition to the existing shell checks):
• Anaphylaxis: 20 kg → 0.2 mg epi IM; 70 kg → 0.5 mg (capped).
• Cardiac: 25 kg → 0.25 mg epi IV in general view and asystole.
• Seizure: 10 kg → D10W 20-50 mL, Lorazepam 1 mg.
Client tsc -b + vite build clean. Bundle 609 kB / 173 kB gz (+28 kB
for three full panels; vite's 500 kB chunk warning noted for later
code-splitting, not blocking).
First batch of real calculator ports, routed through a new
shared/clinical/calculators.ts module that both the server tree and
the React client can import. Kept strictly to the simplest, closed-form
formulas — tables (Rosner BP, Fenton LMS, AAP 2022 bili, Bhutani, CDC
BMI) stay in the vanilla viewer until per-table vector files land.
shared/clinical/calculators.ts
Verbatim ports from public/js/calc-math.js:
• parseAgeMonths / formatAgeMonths — legacy age-string parser
• estimateWeightFromAgeMonths — APLS (Luscombe 2007) + Best Guess
(Tinning 2007) weight-for-age. Cross-checked line-by-line against
calc-math.js:14-39; identical branches, formulas, and roundTo
behavior.
• calculateMostellerBsa — sqrt(h·w/3600), Mosteller 1987.
• calculateWeightBasedDose — generic mg/kg with optional max cap
and mg/mL → mL conversion.
• calculateGcs — 1-15 sum with 8/12 severity thresholds.
shared/clinical/calculators.test.ts
Vitest unit coverage for each helper. Numeric assertions match the
legacy function outputs (3y APLS → 14 kg; 20 kg, 110 cm → 0.782 m²;
15 kg × 100 mg/kg capped at 500 mg, etc.). For these closed-form
formulas the hand-verified expected values are equivalent to a
vanilla-captured vector file — table-driven calculators still need
a JSON fixture before they port.
client/src/pages/Bedside.tsx
Top-level age-to-weight estimator now runs in React
(BedsideWeightEstimator). Formula dropdown switches between APLS
and Best Guess live; weight field accepts a manual override. The
15 clinical dosing sub-modules still fall through to the legacy
viewer via LegacyPanel.
client/src/pages/Calculators.tsx
BSA, Weight-Based Dosing, and GCS panels render real React forms
backed by the shared helpers. PILLS gain a `ported` flag so the
four covered panels (bsa, dose, gcs, + the already-shipped pills)
swap out of the legacy fallback while the others remain linked
out. Result blocks carry data-testid hooks for parity tests.
Config + dep hygiene picked up along the way
• client/tsconfig.app.json: @shared/* path alias, exclude test files
from the React tsc pass.
• tsconfig.json: exclude **/*.test.ts from the backend tsc pass.
• package.json: declare google-auth-library and jszip explicitly —
both were already required() in src/utils/ttsGoogle.ts and
src/routes/learningAI.ts but missing from dependencies, which
would break a clean `npm install`. Also adds engines: node >=20
and convenience verify / verify:full scripts.
• knip.json: quiet now-expected ignoreDependencies / ignoreBinaries
entries for marp-cli, tiptap, cap, etc.
• .gitignore: ignore the .codex CLI marker.
e2e/tests/bedside-react.spec.js
Adds the age→weight parity test: 3y APLS → 14 kg, 3y Best Guess →
16 kg, weight field mirrors the estimator output.
e2e/tests/calculators-react.spec.js
Adds BSA (20 kg, 110 cm → 0.782 m²), dose cap (15 kg × 100 mg/kg,
max 500 mg → 500 mg capped), and GCS (15 → 10 when motor drops
to 1) parity tests.
Client tsc -b + backend tsc --noEmit + vite build all clean.
