NosoGraph v2.4.0 — Evidence Explorer (Legacy prototype)

NosoGraph v2.4.0 — Evidence Explorer

NosoGraph v2.4.0 makes evidence traceability a first-class research experience: open any claim, inspect supporting and contradictory evidence, read provenance, and reach original sources — without treating associations as causation.

Maturity: Public Alpha — research use only; not production clinical software.

What changed

Evidence Explorer

• First-class dashboard navigation (#evidence-explorer) with deep links (?claim_id={uuid}).
• Claim summary (subject · predicate · object), evidence groups, quality badges, provenance timeline, filters, related claims.
• Condition Explorer bridge: Open in Evidence Explorer on claim rows.

Evidence quality

• ADR-001 structured dimensions on each evidence row (species_context, study_design, origin_class, etc.).
• Missing metadata remains unknown — absence is not low quality.

Provenance & sources

• Machine-readable provenance chains and per-evidence source metadata with validated HTTPS links when available.

Condition integration

• Discover claims via GET /api/v1/conditions/{curie}/claims and drill into Explorer from the dashboard.

Reliability

• Playwright fixes for modal overlays and structure API mocks.
• Hosted slow-test workflow green including browser subset (workspace 11/11, explorer 4/4 locally and on Actions).

API changes

• GET /api/v1/claims/{id}/evidence returns a paginated PagedResponse (not a bare array).
• New: GET /api/v1/claims/{id}/related.
• Claim detail adds summary counts and quality on evidence rows.

Upgrade notes

If you called GET /api/v1/claims/{id}/evidence and parsed a JSON array directly, read response.items instead. Claim detail (GET /api/v1/claims/{id}) still embeds inline evidence arrays.

Known limitations

• Heuristic evidence-quality inference; sparse rows stay unknown.
• Compare V2, public demo, and contradiction engine remain future work (Wave 2+).
• No public hosted demo deployment.
