Subcontract (v1)
Subcontract is one of Demiton's published registers for Australian civil construction. The subcontract itself: the instrument, not the subcontractor or the claim. Demiton keeps it current from the systems a contractor already runs and publishes the record's shape as a versioned JSON Schema, so the same question works whichever system produced the record.
