Decision records for the 10 federation topics + the federation-model taxonomy,

event-sourced coordination journal + per-space append authority, server-primary
incremental union, notify-driven freshness, space lifecycle, reference-not-copy
transclusion, detection-core/resolution-policy preset catalog, the federation-
ops capability matrix, and the six selectable/composable federation models.
