Bearer (ck_ endpoint token)

Cost per attributed conversion from Signal's spend-attribution mart, by date, attribution model, channel and campaign: spend, credited_conversions and CAC. Use it for "what does a conversion cost by channel" once Signal is tracking conversions. Rows exist ONLY where credited conversions join ad spend on matching campaign names, so an empty result is a valid state — it means nothing has joined yet, not that CAC is zero and not that the tool failed. Because credit is split by attribution model, always state which model a CAC figure comes from. Requires the Signal spend/CAC mart: without the entitlement this returns a plan refusal rather than empty rows.
