summary: Entity-scoped CAC detail for an analysis period
description: 'Customer acquisition cost for one concrete legal entity and an explicit analysis period (default: year to date). The numerator is explicit CAC-tagged sales & marketing spend (GL classification is reconciliation evidence, never a tag); the denominator is canonical new paying customers, available only with continuous subscription history from before the period start. When `available` is false, `reason` names why and no numeric zero is fabricated. The top-level `available` always equals `metric.available`: a snapshot can compute and still have no ratio (`insufficient_inputs`), in which case `period` and `breakdown` are still returned as evidence while `metric.value` is null.'

Mounting is still conditional: with ONBOARDING_V3_ENABLED false every path below returns the hidden-resource 404 before body parsing or authentication. The header stays defined and is still honoured, because a deployment left at ONBOARDING_V3_QA_ONLY=true keeps requiring it on every path below and 404s unmarked traffic; setting that flag back to true is the rollback. On either setting the header is a pre-company bundle marker, never tenant authorization.
