Biomarker actionability moves from OncoKB to CIViC

OpenOnco is a free public resource, and CHARTER §2 commits it to staying non-commercial. Many of the source licences we depend on are conditional on exactly that. A licence and coverage audit of OncoKB concluded that its terms of service conflict with that commitment, so we moved the biomarker actionability layer to CIViC, which is released under CC0.

The full audit, including the coverage comparison that made the switch defensible clinically and not just legally, is published in docs/reviews/oncokb-public-civic-coverage-2026-04-27.md.

What has landed

• Phase 0 — coverage and licence audit, comparing what OncoKB public data and CIViC each cover for the biomarkers already in the knowledge base.
• Phase 1 (commit 5384348) — engine modules renamed from oncokb_* to actionability_*, the OncoKB proxy service dropped, and the schema generalised behind an evidence_sources block so no single vendor is baked into the data model.
• Phase 1.5 (commit c72e45b) — YAML migration: 29 biomarker files moved from oncokb_lookup to actionability_lookup, and 399 biomarker-actionability files replaced vendor level fields with the evidence_sources block.

What is still open

Phases 2 through 5 are not done: the CIViC reader and fusion-aware matcher, evidence reconstruction for the migrated actionability records, the render and spec updates, and the final verification pass.
