Dahlia Carbon Intelligence, an evidence ledger for emissions

Field notes

The system separates valid time from knowledge time, so later corrections can be appended without rewriting what was known at declaration time. Its calculation layer hashes methodology packs into each result, while sealed bundles carry documents, lineage, and attestation hooks under a Merkle root. The public site also exposes a seeded CBAM/aluminium-extrusion demo, an OpenAPI document, and separate grant-scoped verifier access.
