Command

audit moat [--years xxxx-yyyy] [--period q1|h1|9m|annual] [--wacc 0.xx] [--tax 0.xx] [--help]

Parameter	Description	Default
`--years`	Year range	All years
`--period`	Fiscal period	annual
`--wacc`	Discount rate	0.10 (10%)
`--tax`	Tax rate for NOPAT	0.21 (21%)

Core Metrics

Metric	Formula	Meaning
ROIC Mean		Average capital return
ROIC Stability		Return consistency
Gross Margin CoV		Pricing power stability
Revenue R²	Linear regression	Growth consistency
Economic Moat		Value creation spread

Where:

,
when the sum is non-negative; the raw sum (no tax) when negative. Losses have no tax shield.
Negative NOPAT produces negative ROIC, which participates in the mean.

Key signals:

ROIC > WACC → has moat
ROIC < WACC → no moat, destroying value
ROIC negative → operating loss, no moat
