FDM.4:4.1 - Name the claimed change and prior position

State what is supposed to have changed, for which party, under which arrangement and at what relevant time. Recover the prior position to the extent needed to explain the effect. FDM.1 supplies a missing position account; FDM.2 resolves an uncertain party boundary.

Distinguish a changed permission, duty, usable resource, recorded statement and business outcome. If a message says only “approved”, establish what its sender actually approved before treating it as evidence of another result.
