## Types

### PublicPublisherTechnologiesData

- `technologies` (list of PublicPublisherTechnologiesDataTechnologiesItems, required)
- `state` (enum, required)
  - Allowed values: `observed`, `unknown`
- `provenance` (list of PublicPublisherTechnologiesDataProvenanceItems, required)

### PublicPublisherTechnologiesMeta

- `datasetId` (string, required, nullable)
- `observedAt` (datetime, required, nullable)
- `freshness` ("unknown", required) — Freshness is not certified for this response; timestamps are evidence, not a freshness guarantee
