Water Intake / Hydration Estimator implementation

Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

Computation or source lookup only

Input and validation requirements

The specification does not define activity adjustments, climate effects, or a branch rule, and it permits arithmetic inputs that can yield nonphysical zero values or JavaScript Infinity at extreme magnitudes. Unit ambiguity can also change the result substantially.

Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.

{
  "inputs": {
    "weight_kg": 50,
    "activity_adjustment_ml": 0,
    "climate": "temperate"
  },
  "expected_outputs": {
    "suggested_daily_intake_L": 1.75
  },
  "working": "Base intake = 35 mL/kg/day × 50 kg = 1750 mL/day. Activity adjustment = 0 mL/day. Total = 1750 + 0 = 1750 mL/day. Convert to liters: 1750 ÷ 1000 = 1.75 L/day."
