Leverage

Cache reuse per fresh input. How much an operator leverages cached signal relative to new input.

cache_read, input.

leverage = cache_read / max(input, 1)

Leverage measures how efficiently an operator reuses cached context relative to fresh input.

Verify leverage = cache_read / max(input, 1) for known inputs. Cross-check with 10xDEV = log10(leverage).

The numeric leverage value.

If leverage does not equal cache_read / max(input, 1), the implementation is wrong.

Canonical test. Field data shows leverage distributions across operators.

Does NOT establish causal leverage or business value. High leverage may indicate efficient reuse OR may indicate insufficient fresh input.
