Ethos v0.4.0

Ethos v0.4.0 is a public-beta evaluation release for deterministic document evidence grounding
and citation checking across native Ethos JSON and supported foreign parser outputs.

This release prepares:

  • verification hardening for claim kinds, matching, staleness, resource limits, capability
    downgrades, proof summaries, and application answer-release inputs;
  • additive 1.1.0 verification-config, verification-report, evidence-anchor, and answer-release
    contracts while retaining the supported 1.0.0 forms;
  • a versioned citation-emission JSON contract, dependency-free Python emission helpers for
    LangChain and LlamaIndex-shaped retrieval objects, and model-free walkthroughs;
  • schema-derived TypeScript declarations for verification reports, citation emission, and
    answer-release decisions in @docushell/ethos-pdf;
  • caller-run PDFium setup and ethos doctor checks. Ethos does not automatically download or
    bundle PDFium.

The intended v0.4.0 release surfaces are:

  • Rust library crates ethos-doc-core, ethos-verify, and ethos-pdf at 0.4.0;
  • the Python ethos-pdf wheel at 0.4.0;
  • the npm @docushell/ethos-pdf@0.4.0 CLI package;
  • macOS arm64 and Linux x64 CLI archives with checksums, inventory sidecars, and smoke evidence.

Ethos verifies citation grounding against supplied source representations. It does not establish
semantic truth, and applications remain responsible for relevance, synthesis policy, and final
answer-release decisions.

PDFium-backed commands require caller-provided PDFium through
ETHOS_PDFIUM_LIBRARY_PATH. This release does not bundle a project-maintained PDFium build.

Outside the v0.4.0 release boundary: Windows packaged artifacts, bundled/project-maintained
PDFium builds, ethos-mcp, hosted surfaces, the WASM playground, native OCR or scanned-document
support, Action Marketplace publication, public benchmark reports or comparative claims, speed,
footprint, parser-quality, table-quality, production positioning, ethos-doc, and ethos-rag.
