Understanding Constituent Resource Locus (CRL)

The CRL/FRL pairing is the model’s representation of transformation itself — tracking a resource as it is incorporated into a finished one, so that the act of combination or refinement is captured structurally in the barcode rather than lost. Filling out the CRL is only the first step, since each resource category has its own rule for what the paired Final Resource Locus must be: A constituents always yield an A4* final resource (fixed in place); B constituents can be incorporated into a final resource of nearly any category; C constituents almost always leave the FRL blank and jump straight to the Work Group Locus; D (monetary) constituents branch on role, with investments jumping past the FRL and insurance constituents showing the payout in the FRL; and E constituents always resolve to an E4* (ready-to-consume) final resource. F resources are never staged and so never appear in a CRL at all. This blank-FRL exception, called “jumping,” applies more generally whenever the constituent resource describes most information resources, investment resources, or inputs to the customer’s product, in which case the barcode jumps directly from the CRL to the Work Group Locus.
