- wiki/functional-description.md: rename Overfill Protection → High-volume
Safety; tighten basin-ordering chain; relocate level-based mode
diagrams under wiki/diagrams/modes/level-based/; document the new
flow.predicted.overflow.default position (replaces the previous
child='overflow' under position 'out'); add underflowVolume +
predictedUnderflowVolume entries.
- wiki/modes/{levelbased,powerbased}.md: paragraph cleanups.
- wiki/diagrams: move level-linear basin diagram under modes/level-based/
alongside a new level-log variant.
- simulations/run.js: add max_demand_gt expectation.
- simulations/scenarios/*: minor fixture updates.
- test/basic/nodeClass-config.test.js: new config-shape coverage.
