Constants Registry
Every numerical constant in the calculators is defined once in
shared/constants_registry.json. No magic numbers anywhere
in the calculator HTML. Each entry carries a source_id that
resolves to a public, citable authority.
| Symbol | constant_id | Value | Units | Type | Source | Note |
|---|
Editing rule. A constant is edited in
constants_registry.json
only with a matching change in shared/source_registry.json.
The deploy lint enforces source-attribution presence.
