v0.2.1

NosoGraph v0.2.1 — Stabilization

Backward-compatible stabilization patch for the v0.2.0 Compare V2 milestone. No new features, no public API changes, and no changes to Compare V2 biomedical semantics, fingerprints, exports, or replay behavior.

Fixed

• Timezone-aware UTC timestamps in the asynchronous job queue, target hypothesis agent, and dossier web flow; machine-facing serialized timestamps carry an explicit UTC offset while filename-safe tokens retain their exact YYYYMMDDTHHMMSSZ shape.
• Open Targets ingestion normalizes optional phase data at an explicit boundary (integer/numeric-string phases become integers; missing, null, boolean, malformed, or unsupported values become no phase instead of crashing import) and types snapshot identifiers as UUID values with deterministic import behavior preserved.
• Compare V2 validates persisted status at the storage boundary: comparable and insufficient_data round-trip unchanged; unknown stored statuses are invalid persisted data following the existing persistence-error path rather than a raw validation error or silent coercion to insufficient_data.
• Disease discovery excludes the transient zz_scaffold_test test fixture so parallel test execution no longer leaks it into registry sampling.

Changed

• The informational mypy ratchet (make typecheck) now covers the recently shipped stabilization surfaces (Open Targets import adapter, biomed/nosograph_compare/, dossier API/router/service); those files type-check cleanly.
• Removed obsolete dossier-service type-suppression comments after confirming the optional WeasyPrint/ReportLab imports are typed correctly; PDF fallback behavior is unchanged.
• Technical-debt ledger refreshed with a prioritized active backlog separating current open work from the completed historical audit.
• Public package, runtime, citation, CodeMeta, roadmap, and documentation metadata advance to v0.2.1. v0.2.1 has no Zenodo archive record yet, so citation metadata uses the all-versions concept DOI; the v0.2.0 version DOI remains historical metadata for v0.2.0 only.

Known limitations

• Third-party warnings remain visible and documented: FastAPI/Starlette TestClient's future httpx2 migration and SHAP/Matplotlib color-map deprecations (dependency-family work deferred to the ledger).
• The mypy ratchet across remaining legacy runtime boundaries (59 known errors in 45 previously checked files) continues as incremental debt work.
