-Settler has no operational config of its own — all behaviour is driven by the runtime state (`F_in`, `Cs_in`, `C_TS`). Tune behaviour by feeding it different reactor effluents or `C_TS` measurements.

 ## 10. State chart
 
-Skipped — settler is stateless. Each `stateChange` (or `data.influent`, or `quantity (tss)` update) recomputes the 3 Fluent streams from scratch.
+Not applicable — settler is stateless. There is no FSM. Every trigger (`stateChange` from the reactor, `data.influent`, or a `quantity (tss)` update) causes a fresh recompute of the 3 Fluent streams from the current runtime state and the split immediately re-emits.
