statfidelity 0.1.0 (2026-09-03)

Release scope

• Provides a ten-dimensional statistical-fidelity audit covering semantic, numerical, temporal, geographic, unit, contextual, provenance, revision, transformation, and uncertainty fidelity.
• Provides geometric and weakest-link summaries together with non-compensatory critical-error rules and PASS/WARN/FAIL certification logic.
• Provides provenance graphs, revision handling, portable SHA-256 proof bundles, batch auditing, prompt perturbation, statistical red-team generation, minimal-pair tests, benchmark utilities, and model-stability tools.
• Provides bounded interfaces for Eurostat, World Bank, OECD, UNSD SDG, UK ONS, U.S. BLS, and low-level IMF SDMX URL construction, together with an extensible HTTPS JSON API registry.
• Provides gsbpm52_map(), gsbpm_align(), and gsbpm_quality_report() for explicit alignment with relevant GSBPM 5.2 Analyse, Disseminate, Evaluate, Quality Management, and Metadata Management activities.
• Includes offline fixtures and regression tests for provider parsing, audit behaviour, proof integrity, and GSBPM alignment.

Scope and compatibility

• GSBPM alignment is offline and deterministic and introduces no additional network dependency.
• The package supports relevant GSBPM 5.2 activities but does not claim to implement or certify the complete GSBPM statistical production process.
