OSDU reference implementation

Two emissions-integrity domains — geological CO₂ storage and methane MRV — modelled in Open Footprint, deployed onto a live OSDU Data Platform, and driven through their full certification lifecycles including the anomaly cascades that revoke certification.

Interactive consoles

Drive the lifecycles

Each console shows live certification state, the immutable version timeline, the constraint gate, the attestation, and a searchable record index — plus one write action that moves the state machine.

CCUS · Storage Complex Evidence Pack

Decatur CO₂ storage certification

An evidence pack certified against seven EPA UIC Class VI constraints, then suspended when a plume observation breached the Area of Review — cutting the carbon claim and revoking the attestation.

ISO 25624-1 reconcile & restate

A source-level inventory reconciled against a site measurement, verified Gold Standard, then formally restated after an unlit flare was caught as a super-emitter — with the OFP five-domain graph behind it.

The bundle

What ships alongside these consoles

The reference implementation is self-contained: it regenerates the model, replays it onto any OSDU, and verifies itself with no network.

Path	What it is
ccus-scep/	Schema generation from the SysML v2 model, the Class VI certification gate, the anomaly cascade, and the exported evidence.
methane-mrv/	The ISO 25624-1 lifecycle, the restatement, the OFP five-domain grounding, and a 342-record evidence bundle with every version body.
ofp-schema-deploy/	The OFP → OSDU schema pipeline: canonical kind ids taken from the Open Footprint model itself.
methane-mrv/verify_export.py	Re-derives the whole proof from the export with no network — 23 checks.
methane-mrv/restore_claim3.py	Replays schemas and records onto any OSDU platform, remapping partition-scoped ids.

Synthetic data. Both sites are illustrative — Decatur is modelled on the public IBDP geology, MRV-01 on ISO 25624-1's own worked example. Thresholds and the LEI are demo parameters, not measured or registered values.
