Provenance and freshness

  • CCA Entities production contract: Version 0.1.0 implementation, OpenAPI contract, aliases, documentation, llms.txt, RFC 9727 catalog, and ETag behavior verified at repository commit b7811bec94b84f245696041cd8f1279fa2d7cd38 and production Worker version becef229-6c77-4424-82ff-c7b6be26ae62. Source
  • Initial SEC EDGAR release: The completed sec-edgar cycle 2026-09-02 release contains 8,005 entities and 28,829 identifiers with zero rejects; live public status reports one complete release, no active release, no open conflicts, and healthy fresh capacity below 1% on the largest database. Source
  • Published data limitations: Documents material and known limits for contractor headcount, private-company financials, EIN and domain coverage, registry variation, and release-based rather than real-time freshness. Source
  • Machine-readable API discovery: Live OpenAPI 3.1, HTML documentation, llms.txt, and RFC 9727 linkset describe the public read-only integration surface. Source

Update cadence: The populated SEC EDGAR source is checked daily and published through immutable, release-based cycles; the current cycle is 2026-09-02, completed 2026-09-04. Other configured sources range from continuous and daily to weekly, monthly, as-needed, or jurisdiction-dependent and are not claimed as populated.
Metadata verified: 2026-09-04

Governance: Production version 0.1.0 remains beta but is operational following the complete initial SEC release: 8,005 entities, 28,829 identifiers, and zero rejects. The cca-entities service owns the ecgc namespace. Public status is sanitized, topology-safe, and fresh; deep readiness, per-shard capacity, administration, and release mutation remain private. Public reads are mirror-only and release-based rather than real-time. Current populated coverage is SEC EDGAR; configured GLEIF, IRS Exempt Organizations, state registry, Wikidata, and CCA sources do not imply populated coverage. Private-company financials, contractor headcount, EINs, domains, and registry fields remain incomplete, provenance-dependent, and may be null. No corpus completeness is claimed.

Agent readiness

Partial · 88/100 88%

OpenAPI 3.1, HTML documentation, llms.txt, RFC 9727 discovery, examples, operation identifiers, provenance, limitations, and topology-safe status are live. Agent use must remain source- and release-aware because version 0.1.0 is beta, only SEC EDGAR is currently populated, and documented fields may be null.
