UppercaseSnakeForTrueConstants [rule] v0.1.0

Reserve UPPER_SNAKE_CASE for top-level program-wide constants whose value is fixed for the lifetime of the program and is also a primitive or deeply frozen value. Not every const deserves UPPER_SNAKE_CASE — only the ones that act as named magic values.

Checks

• The binding is at module scope (not a local const inside a function).
• The value is a primitive, a frozen object, or otherwise not meaningfully mutable.
• The name reads as a constant the consumer must not change: MAX_RETRIES, DEFAULT_TIMEOUT_MS, API_BASE_URL.
• Ordinary local const bindings stay in camelCase — const user = await fetchUser() is camelCase, not UPPER_SNAKE.

Label

Use UPPER_SNAKE_CASE only for module-level deeply-immutable constants
