OPB METHODOLOGY
ORR Pin Bridge (Explainer Rail)
ORR is the change-control rail for this Explainer — one FFIEC stack per cvr_cycle_id, one narrative pin per pre-close deal.
Deal teams should recognize these TRNSFM markings; OPB foots them at the Explainer cut plane for client-side audit.
Me = slice @ pin. Them = merged standalone @ pin. Post-close absorption is a lineage assumption only.
PRC bridge reads Smartmarkets LIBRARY at pin-replayed org_keys — same accretion instrument as forward minted DealCard, just with a past-tense exemplary cut.
See Prompt Chip for the production mint on your next deal. This Review Explainer trains the bridge — not production mint (you will not be able to mint this deal card; Them is already rolled under).
