Incoming review checks resin identity, melt flow, moisture, and a supplier certificate but excludes the feedstock's product and processing lineage. Prior heat and ultraviolet exposure, molecular-chain scission, pigments, fillers, flame retardants, plasticizers, and incompatible-polymer residues can therefore enter the new compound without being intentionally selected or represented by the nominal grade. Lots that pass routine incoming checks may behave differently during molding or after service aging because their inherited conditions conflict with the new structural use.","actors":["Recycled-resin supplier and sorting operator","Materials quality lead","Polymer formulation scientist","Analytical laboratory technician","Molding process engineer","Product safety or reliability engineer","Procurement owner","Production release authority"],"observable_state":"For each recycled-resin lot, the plant can observe a nominal polymer grade, supplier certificate, melt-flow result, moisture result, and short molding trial, but cannot link the lot to source-product categories, prior service exposure, wash and reprocessing history, blend events, additive families, or earlier thermal cycles. Retained samples may also show unexplained variation in spectroscopy, thermal transitions, ash content, molecular-weight proxies, molding pressure, odor, color, or aged mechanical behavior.","consequence":"An inherited contaminant, additive package, or degradation state can remain latent at receipt, then cause unstable processing, weak interfaces, accelerated embrittlement, stress cracking, or inconsistent failure behavior in the finished structural compound. Because multiple products may consume the same pooled lot, one lineage blind spot can create a concentrated cross-product quality and safety exposure.","affected_objective":"Maintain reproducible processing and defensible structural performance while using recycled polymer feedstock without silently accepting material history that is incompatible with the intended service conditions.","intervention":"Establish a lot-level recycled-feedstock lineage audit before structural-use release. Bound each lot as an inherited substrate; record source-stream categories, collection and sorting routes, blend events, prior-use information, washing and reprocessing steps, and declared additive families; identify how inherited chemistry and degradation travel into the new compound; compare those origin conditions with the target part's temperature, load, chemical exposure, and lifetime; and assign each lot to release, restricted use, controlled blending, additional testing, isolation, or rejection. Use analytical fingerprints and a virgin-resin clean reference to resolve material lineage where documentary provenance is incomplete, and retain an explicit owner and refresh trigger for accepted residual uncertainty.","structural_mapping":[{"archetype_element":"Borrowed substrate","domain_realization":"Each pooled lot of post-consumer recycled polymer used as the base resin for a new
