Sea-to-Shore
Loop Bench

Reframe the ocean's "bounty" as a set of reciprocal loops. Pick one contribution and one disruption, then watch six flows reroute through channels and mechanical gates — revealing what depends on what.

Return Note

reroute reading
  • Strongest dependencyOcean Source — everything downstream leans on it (dependency 9/10).
  • Main bottleneckCare & Maintenance — narrowed by "Maintenance delay" (upkeep 9/10, delay 8/10).
  • Compensating routeA substitute path carries flow around Care & Maintenance → Processing & Making, but at lower capacity and higher uncertainty.
  • Deferred costProcessing & Making pays later: pressure deferred here instead of resolved, raising future upkeep.
  • Unresolved uncertaintyReturn to Sea stays unsettled (uncertainty 6/10) — outcomes remain provisional.
Reciprocal actionGive back rest to the source that fed the loop.
