-|---|---|---|---|
-| `set.mode` | `setMode` | `string` | Replaces the named state value with the supplied payload. |
-| `cmd.startup` | _(none)_ | `any` | Triggers an action / sequence — not idempotent. |
-| `cmd.shutdown` | _(none)_ | `any` | Triggers an action / sequence — not idempotent. |

-| `set.position` | `execMovement` | `object` | Replaces the named state value with the supplied payload. |
-| `data.flow` | `updateFlow` | `object` | Pushes a value into the node's measurement stream. |
-| `query.curve` | `showcurve` | `any` | Read-only query; node replies on the same msg. |
-| `child.register` | `registerChild` | `string` | Parent/child plumbing — registers or unregisters a child node. |
+| Canonical topic | Aliases | Payload | Unit | Effect |
+|---|---|---|---|---|
+| `set.mode` | `setMode` | `string` | — | Switch the valve between auto / manual control modes. |
+| `cmd.startup` | _(none)_ | `any` | — | Initiate the valve startup sequence. |
+| `cmd.shutdown` | _(none)_ | `any` | — | Initiate the valve shutdown sequence. |
+| `cmd.estop` | `emergencystop`, `emergencyStop` | `any` | — | Trigger an emergency stop on the valve. |
+| `execSequence` | _(none)_ | `object` | — | Legacy umbrella that demuxes payload.action to startup / shutdown / estop. |
+| `set.position` | `execMovement` | `object` | — | Move the valve to a control-% position via execMovement. |
+| `data.flow` | `updateFlow` | `object` | — | Push a measured flow into the valve (variant + position + unit). |
+| `query.curve` | `showcurve` | `any` | — | Return the valve characteristic curve on the reply port. |
+| `child.register` | `registerChild` | `string` | — | Register a child measurement with this valve. |
