THINK produces one traveling substance — Thought (the renamed bone family). Player effects are sinks at the target: a camera claim is a reservoir filling from real wire routes; auto-process and senses are persistent taps. The core becomes the passive-draw sink of last resort, overridden by any local sink in gravity range, so quiet deep racks are research farms and the frontier spends the research stream. Reverses issue #3's 'knowledge is not operation fuel' with Cameron's explicit agreement; PendingOpsJob dockets are the migration base. Defense: design capture amending wiki/mechanics/machine-work.md (ops bullet superseded, core-sink bullet amended, taxonomy rename, flow render rule, criterion 10, new OPENs); no src change in this work order — runtime migration is dispatched under ROADMAP #33.
