What Would Need to Be True
Primary-text verification: does the Arthashastra itself articulate the dharma-as-output framing, or is this Pillai's reconciliation that the text leaves implicit?
Comparative analysis: do other strategist-pedagogues (Krishna, Machiavelli, etc.) articulate the same reconciliation, or is each one's resolution different in ways that matter?
Operational test: does the framing produce different decisions than pure deontology AND different decisions than pure consequentialism in real cases? If it collapses into one or the other, the reconciliation is rhetorical rather than structural.
