Properties
| Name | Type | Description |
|---|---|---|
| abn | string | The contractor's Australian Business Number — the registration's identity coordinate (`contractor_abn` on the fact; `abn` in the payload). |
| scheme | string | The prequalification scheme the registration is under, e.g. one of `tfnsw_r_levels`, `nsw_construction`, `vic_csr`, `qld_tmr`, `federal_npp`. |
| status | string | The registration's state; parser defaults `"active"` when the source omits it. The tenant projector consumes **only** `"active"` rows, so a wrong default silently changes what tenants see. |
| expires_at | string | When the registration lapses. |
| entity_name | string | The registered entity's trading/legal name, when the classifier file carries it. |
| observed_at | string | When the registration was observed; the gate requires it and the router derives it from `registered_at`, falling back to the harvest time. |
| region_code | jurisdiction | The jurisdiction the scheme belongs to, derived from `scheme`; unmapped schemes log and leave it NULL (`:609-613`), and the partition bucket falls back to `OTHER`. |
| registered_at | string | When the registration took effect; also the preferred `observed_at`. |
| classification | string | The grade/level held under that scheme. |
| source_dataset | string | Producer identity; the atom's `source_system` lowercased — `"classifier_repo"` as written today. |
