Evidence and estimation contract

The evidence contract should evidence from commerce platform, analytics, CRM, inventory and finance and preserve it in the commerce margin cockpit. Connect market themes such as contribution margin; new-customer quality; repeat purchase with validation signals including qualified sessions; product views; cart progression; stock coverage and diagnostics such as product; category; channel; cohort; promotion; device. Label every input as observed, disclosed, surveyed, derived, assumed or modeled, and show transformations, currency basis, inflation treatment and double-counting controls.

Bias and uncertainty tests

A rigorous review asks whether revenue can grow while margin, returns or customer quality deteriorate, survivorship bias, incompatible definitions, stale sources, private-company gaps, bundled revenue, gross-versus-net inconsistency and false precision. Segment only by product; category; cohort; channel; market; device when the evidence remains decision-useful.
