Graph Orchestrator

An LCA calculation graph built for each recipe from the sum of all tributaries — the way EOS's RETE engine does, but over the federated tributary inventories rather than a flat factor table. Two policies run every night, fully offline, with no memoised EOS values: parity replicates EOS's decision structure, and optimal resolves against geography- and year-specific tributary context builds. Both are compared to the EOS production anchor. Every recipe links to its graph in the Firefly composer.

Robust median = median |Δ%| vs EOS on fully-resolved recipes with an EOS value ≥ 200 g (segments out single-portion caterer anchors whose tiny denominators inflate relative deltas). Data: orchestrator-data.json, rebuilt by the lci-orchestrator nightly.
