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.

Co-Authored-By: Codex + vendor model Opus 4.7 (1M context) <noreply@anthropic.com>
First Bedside commit. Delivers the /app/bedside page with the full
15-pill sub-nav in the same order + labels as the vanilla app, and
switches the sidebar Bedside link to available.
client/src/pages/Bedside.tsx
Single-file shell. PILLS array is the single source of truth for
pill ID / label / icon / summary, ordered to match
public/components/bedside.html (neonatal, airway, cardiac,
respiratory, ventilation, seizure, sepsis, anaphylaxis, sedation,
agitation, antiemetics, antimicrobials, burns, toxicology, trauma).
Clicking a pill flips useState<active>, and LegacyPanel renders a
summary of that module + a button to open the legacy Bedside tab.
What is intentionally NOT in this commit
Each pill's actual clinical dosing panel stays in vanilla for now.
Those panels encode weight-based dosing, syndrome-keyed
antimicrobials, and PALS / ALS formulas — exactly the class of
content the migration checkpoint memory flags as must-not-be-
"simplified" by an LLM. They belong in per-module commits that
land alongside the calculators port (APLS + Best Guess weight,
Fenton 2013 LMS, AAP 2022 bilirubin, Rosner BP splines) where
test vectors can verify byte-for-byte parity with the vanilla
output.
The top-level age → weight estimator also waits on calculators —
it calls window._PED_MATH.estimateWeightFromAgeMonths in the
vanilla module, which is defined in public/js/calculators.js.
e2e/tests/bedside-react.spec.js — three smoke tests
All 15 pills render by data-testid, clicking a pill swaps the
panel, and the legacy-viewer link is present. The pill-order list
is hard-coded in the spec so re-ordering or dropping a pill trips
a loud failure.
Client tsc -b + vite build clean. Bundle 456.71 kB / 130.53 kB gz.
