Platform contractor stats

Platform contractor stats is one of Demiton's published registers for Australian civil construction. Per-contractor statistics rolled up from awarded contracts. 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.

Part of Platform in the register catalog.
