style: palette swatch → (domain-hue redesign 2026-05-21)

Sidebar swatch now follows function family rather than S88 level, so the
palette is visually identifiable instead of monochromatically blue. Editor-group
rectangles in flow.json still follow S88 — only the registerType color changed.
Full table + rationale: superproject .claude/rules/node-red-flow-layout.md §10.0
and .claude/refactor/OPEN_QUESTIONS.md (2026-05-21 entry).

+## Limitations vs `rotatingMachine`

+- **No `maintenance` state machine.** The schema's `mode.current` enum
+  accepts `maintenance` (gates sources via `isValidSourceForMode`), but
+  the FSM has no `entermaintenance` / `exitmaintenance` states and the
+  `sequences` schema declares only `startup`, `shutdown`, `emergencystop`,
+  and `boot`. Configuring `maintenance` mode therefore disables external
+  command sources but does not put the valve through a maintenance
+  sequence. Aligns with valve's role as a passive flow-controlled
+  actuator; lift to RM-style FSM if/when site maintenance procedures
+  require explicit state transitions.

 | Canonical topic | Aliases | Payload | Unit | Effect |
-|:---|:---|:---|:---|:---|
-| `set.mode` | `setMode` | `string` (`auto` / `virtualControl` / `fysicalControl` / `maintenance`) | &mdash; | Calls `source.setMode(payload)`. Invalid mode logs `warn` and is dropped. |
-| `cmd.startup` | &mdash; | `{ source?: string }` | &mdash; | `source.handleInput(payload.source ?? 'parent', 'execSequence', 'startup')` &mdash; runs the configured `startup` sequence (default `[starting, warmingup, operational]`). |
-| `cmd.shutdown` | &mdash; | `{ source?: string }` | &mdash; | `source.handleInput(..., 'execSequence', 'shutdown')`. Pre-shutdown the valve ramps to position 0 if currently `operational`. |
-| `cmd.estop` | `emergencystop`, `emergencyStop` | `{ source?: string, action?: string }` | &mdash; | `source.handleInput(payload.source ?? 'parent', payload.action ?? 'emergencystop')` &mdash; runs the `emergencystop` sequence (default `[emergencystop, off]`). |
-| `set.position` | `execMovement` | `{ source?: string, action?: string, setpoint: number }` | control % (no `units`; no `percent` measure in convert) | `source.handleInput(..., 'execMovement', Number(payload.setpoint))` &mdash; moves the valve to a position via `state.moveTo`. |
-| `data.flow` | `updateFlow` | `{ variant, value, position, unit? }` &mdash; `variant ∈ {'measured','predicted'}` | `volumeFlowRate` (default `m3/h`) | `source.updateFlow(...)` &mdash; pushes a flow value into MeasurementContainer at `<position>` and triggers a deltaP recompute. |
-| `query.curve` | `showcurve` | any | &mdash; | `source.showCurve()` &mdash; replies on **Port 0** with `{ topic: 'Showing curve', payload: <result> }` via `ctx.send`. |
-| `child.register` | `registerChild` | `string` (child node id); `msg.positionVsParent` carries the position label | &mdash; | Resolves the child via `RED.nodes.getNode(payload)` and registers it through `childRegistrationUtils.registerChild(child.source, msg.positionVsParent)`. The valve's `registerChild` records the child for fluid-contract tracking. |
-| `execSequence` | &mdash; (legacy umbrella, `_legacy: true`) | `{ source, action, parameter }` with `action ∈ {'startup','shutdown','emergencyStop','emergencystop'}` | &mdash; | Content-based router: forwards to canonical `cmd.startup` / `cmd.shutdown` / `cmd.estop` based on `payload.action`. Unknown action logs `warn`. Prefer the canonical `cmd.*` topics. |
+|---|---|---|---|---|
+| `set.mode` | `setMode` | `string` | — | Switch the operating mode. Allowed: `auto`, `virtualControl`, `fysicalControl`, `maintenance` (schema-validated in `valve.json` → `mode.current`). |

+| `cmd.shutdown` | — | any | — | Initiate the valve shutdown sequence. |

+| `data.flow` | `updateFlow` | `object` | — | Push a measured flow into the valve (variant + position + unit). |
