New vendor adapters must provide: a conservative detector, an importer that creates canonical tables, explicit timestamp and coordinate semantics, loss-aware retention of unknown fields, synthetic fixtures, and tests against multiple real export versions where licensing permits.
Experimental models must include a declared estimand, assumptions, simulation or parameter-recovery evidence, failure diagnostics, and responsible-use notes. Do not label derived components as attention, effort, engagement, or cognitive load without a defensible validation argument.
