 The registry lives in `src/commands/index.js`. Each descriptor maps a canonical `msg.topic` to its handler; aliases emit a one-time deprecation warning the first time they fire.

-| `data.influent` | `influent`, `setInfluent` | `{F: number, C: number[13]}` &mdash; either field optional | `F` in m³/h, `C[*]` in mg/L | Replaces influent flow and/or the 13-species concentration vector on the domain (`source.F_in`, `source.Cs_in`). Triggers `notifyOutputChanged`, which re-emits the 3-stream Fluent envelope on Port 0. |
-| `child.register` | `registerChild` | `string` (child node id) | &mdash; | Register a child node (measurement / reactor / machine) with this settler. Port 2 wiring does this automatically in normal flows; the explicit handler exists because `BaseNodeAdapter` does not have an implicit registration path. |
