Release 001
7 September 2026. DrillFlowCore, BBIPEvidenceCore, EFSTagCore and ExplorationEvidenceCore are published as a deliberately limited interoperability layer under MPL-2.0.
Licence model
Covered source is publicly licensed under MPL-2.0. BBIP retains copyright in BBIP-authored code and may separately offer BBIP-owned code or later BBIP-owned versions under commercial or proprietary terms. Existing MPL-2.0 grants remain effective. The public release does not itself grant a separate commercial licence.
Boundary
The engineering-specific split is published with the release. Production security and authority, private persistence/reconciliation, customer/site content, operational datasets, diagnostic decision logic and other specialised proprietary implementation remain outside the open core.
