SAM Attachment Evidence
Captured public notice attachment metadata, document content, source evidence and observed versions.
Source, grain and coverage
Progressively acquired public files. Discovery, permitted download, extraction and search coverage are reported separately; the complete SAM attachment total is unknown.
Public captured SAM attachments only; acquisition, file extraction and indexing have separate partial coverage. Zero stored rows does not mean SAM has no attachments. Unsupported, restricted, failed and pending files cannot support content-based negatives. Consult the attachment status endpoint. Semantic and reranking availability is reported at runtime; generic dataset queries support structured and lexical predicates. Counts apply to the declared stored dataset grain, never all SAM files.
Collection schedule: Bounded scheduled discovery and processing; inspect live source status..
Records describe public source observations. Missing values remain unknown; historical observations do not establish current status.
Definitions audited . Use source status and the returned watermarks to inspect current collection health.

The primary dataset is sam_attachments. Select another dataset from this source with dataset_id. Supported field names can be used as exact filters; the versioned query endpoint also supports declared ranges and list operators.
Through canonical /mcp, use govbiz_discover_datasets, govbiz_describe_dataset, govbiz_search_records, and govbiz_get_evidence. Cross-source relationships use govbiz_get_related_records and require access to every involved domain.

sam_attachments · Schema 1
One current public attachment reference per attachment_id; equal file bytes across notices remain distinct references.
Search modes: structured, lexical. History: Current retained projection; exact historical reconstruction is unsupported.
Measures: record_count. Monetary values use decimal strings with declared units. Unknown amounts do not become zero.
