        - `methodologyVersion` string
        - `materializationVersion` string
        - `object` 'factor_bulk_return', required
        - `responseMode` 'compact' | 'standard' | 'verbose': Projection used for this resource. compact is token-efficient for agents; standard and verbose retain fuller operational context.

        - `disclosures` string[]: Short product/legal disclosures for research-scenario outputs. Omitted on low-risk compact responses.

          - `retrievedAt` string, required
          - `parserVersion` string, required
        - `freshness` FreshnessMetadata: Freshness of the record. For SEC filings, freshness measures the delay between SEC acceptance (`sourcePublishedAt`) and when the record became available in the API — not the age of the document. Statuses: `current` (recently published and available promptly), `archival` (an immutable historical document held in full; its availability delay is not a freshness signal), `degraded`/`stale` (a recently published filing that became available later than the freshness thresholds allow), `fresh` (continuously refreshed datasets recently observed at source), `unknown` (no timestamps). An old immutable filing is never `stale` simply because it was published long ago. `lagMs` is the publish-to-availability delay in milliseconds.
