US Federal Procurement Attachments

United States · обновления: daily · us-procurement-attachments

The documents behind SAM.gov contract opportunity notices — solicitations, statements of work, amendments — as extracted PDF text, one record per attachment, joined to us-federal-procurement by notice ID. Extraction is gated on measured quality checks: scanned images and unreadable text layers are refused and counted, every record carries an extraction attestation naming the extractor, page count and yield, and only extracted text ships — the binary is never stored. Every record carries its source URL, fetch timestamp, HTTP status and the SHA-256 of both the raw response and the extracted record. Every release ships a manifest with every file’s SHA-256 and a Merkle root over every chunk hash, which the buyer can recompute from the downloaded files. record_id and chunk_id are stable across releases. Personal data is screened out inside the pipeline before any hash is computed.
