Attribution event matching
Match supplied click/event identities, windows and credit rules without invented results.
Match a conversion to a supplied click window
Check visitor identity and a half-open elapsed window before proposing a credit link.
Hold a last-touch credit when eligible clicks tie
Keep a same-time tie unresolved instead of using row order as a hidden priority.
Revise attribution after a conversion timestamp is corrected
Recompute the supplied credit link and preserve the old attribution revision as history.
Report one primary conversion credit beside earlier assists
Keep touch roles separate so assists are not added to the exclusive conversion total.
Apply event-time and arrival-grace windows independently
Distinguish an in-window conversion from one that arrived too late for automatic inclusion.
