The value-chain toolkit reorganises Biojet Node by actor, not function. Every step tags the specific SARP / SCS clause it satisfies, so the toolkit acts as a compliance scaffold — not just a reference. Waste collector and producer flows ship in v0; aggregators, certifiers, blenders, and corporate offtakers follow once we have usage signal.
UCO aggregators, MSW operators, slaughterhouse residue collectors, cassava-residue suppliers. Four flows: eligibility check, chain-of-custody template, mass-balance reconciliation, find-a-producer.
HEFA / FT / ATJ / co-processing plants. Four flows: LCA eligibility (CORSIA + EU RED III side-by-side), pathway recommendation, sustainability evidence kit, CORSIA attestation walk-through.
