# The usage context store, proved end to end (novox/hq ADR 0054). A postgres PROVIDER and the
# model-usage CONSUMER ride one node; the substrate (store, broker, control) owns the other. As in
# two-node-db, the app-postgres provider and the mesh's own substrate store both want host port 5432,
# so they cannot share a machine — the substrate lives on `anchor` and NOTHING else, and `laptop`
# runs postgres plus model-usage. Provider and consumer are co-located on laptop, so only enrolment
# crosses to anchor, over the underlay both machines already share.
#
# The property the bed proves: a usage event emitted into the mesh is upserted into model-usage's
# provisioned postgres store, at BOTH grains (licence and session, differing only in `consumer`),
# LATEST-per-key, and IN THE CLEAR — an ordinary select returns the numeric value and its raw payload.
