Sinus inflow: 54-270 m³/h (base 0.015 + amplitude 0.06 m³/s), 4 min
period. Peak needs 1-2 pumps, never all 3 = realistic headroom.
PS control: continuous proportional demand when level > stopLevel, not
just when > startLevel && filling. Pumps now ramp down smoothly as
basin drains toward stopLevel instead of staying stuck at last setpoint.

Three fixes:
1. PS outflow triple-counted (pumpingStation c62d8bc): MGC registered
twice + individual pumps registered alongside MGC + dual event
subscription per child. Now: one registration per aggregation level,
one event per child. Volume integration tracks correctly.
2. All 3 pumps always on: minFlowLevel was 1.0 m but startLevel was
2.0 m, so at the moment pumps started the percControl was already
40% → MGC mapped to 356 m³/h → all 3 pumps. Fixed: minFlowLevel
= startLevel (2.0 m) so percControl starts at 0% and ramps
linearly. Now pumps graduate: 1-2 pumps at low level, 3 at high.
3. Generalizable registration rule added as code comments: when a group
aggregator exists (MGC), subscribe to it, not its children. Pick
one event name per measurement type per child.
E2E verified: 2/3 pumps active at 56% fill, volume draining correctly,
pump C at 5.2% ctrl delivering 99 m³/h while pump A stays off.

generalFunctions 29b78a3 -> 086e5fe:
Schema default machineCurve.nq had a dummy pressure slice at key "1"
with fake data. Deep merge injected it alongside real curve data,
pulling the pressure-dimension spline negative at low pressures.
Fix: default to empty {nq: {}, np: {}}.
rotatingMachine 26e253d -> 510a423:
Tests updated for corrected fValues.min (70000 vs old 1).
Trace instrumentation removed. 91/91 green.

Architecture change: demo is now driven by a sinusoidal inflow into the
pumping station basin, rather than a random demand generator. The basin
fills from the sinus, and PS's levelbased control should start/stop
pumps via MGC when level crosses start/stop thresholds.
Changes:
- Demo Drivers tab: sinus generator (period 120s, base 0.005 + amp 0.03
m³/s) replaces the random demand. Sends q_in to PS via link channel.
- PS config: levelbased mode, 10 m³ basin, startLevel 1.2 m / stopLevel
0.6 m. Volume-based safeties on, time-based off.
- MGC scaling = normalized (was absolute) so PS's percent-based level
control maps correctly.
- Dashboard mode toggle now drives PS mode (levelbased ↔ manual) instead
of per-pump setMode. Slider sends Qd to PS (only effective in manual).
- PS code (committed separately): _controlLevelBased now calls
_applyMachineGroupLevelControl + new Qd topic + forwardDemandToChildren.
KNOWN ISSUE: Basin fills correctly (visible on dashboard), but pumps
don't start when level exceeds startLevel. Likely cause: _pickVariant
for 'level' in _controlLevelBased may not be resolving the predicted
level correctly, or the safetyController is interfering despite
time-threshold being 0. Needs source-level tracing of the PS tick →
_safetyController → _controlLogic → _controlLevelBased path with
logging enabled. To be debugged in the next session.

Each node repo now has a CLAUDE.md that declares its S88 hierarchy
level (Control Module / Equipment Module / Unit / Process Cell), the
associated S88 colour, and the placement lane per the superproject's
flow-layout rule set (.claude/rules/node-red-flow-layout.md).
The rule set lives in the superproject only (single source of truth).
Per-node repos reference it. When Claude Code opens a node repo, it
reads the local CLAUDE.md and knows which lane / colour / group to
use when building a multi-node demo or production flow.
Submodule pointer bumps for all 11 nodes.

New top-level examples/ folder for end-to-end demos that show how multiple
EVOLV nodes work together (complementing the per-node example flows under
nodes/<name>/examples/). Future end-to-end demos will live as siblings.
First demo: pumpingstation-3pumps-dashboard
- 1 pumpingStation (basin model, manual mode for the demo so it observes
rather than auto-shutting pumps; safety guards disabled — see README)
- 1 machineGroupControl (optimalcontrol mode, absolute scaling)
- 3 rotatingMachine pumps (hidrostal-H05K-S03R curve)
- 6 measurement nodes (per pump: upstream + downstream pressure mbar,
simulator mode for continuous activity)
- Process demand input via dashboard slider (0-300 m3/h) AND auto random
generator (3s tick, [40, 240] m3/h) — both feed PS q_in + MGC Qd
- Auto/Manual mode toggle (broadcasts setMode to all 3 pumps)
- Station-wide Start / Stop / Emergency-Stop buttons
- Per-pump setpoint slider, individual buttons, full status text
- Two trend charts (flow per pump, power per pump)
- FlowFuse dashboard at /dashboard/pumping-station-demo
build_flow.py is the source of truth — it generates flow.json
deterministically and is the right place to extend the demo.
Bumps:
nodes/generalFunctions 43f6906 -> 29b78a3
Fix: childRegistrationUtils now aliases the production
softwareType values (rotatingmachine, machinegroupcontrol) to the
dispatch keys parent nodes check for (machine, machinegroup). Without
this, MGC <-> rotatingMachine and pumpingStation <-> MGC wiring
silently never matched in production even though tests passed.
Demo confirms: MGC reports '3 machine(s) connected'.
Verified end-to-end on Dockerized Node-RED 2026-04-13: pumps reach
operational ~5s after deploy, MGC distributes random demand across them,
basin tracks net flow direction, all dashboard widgets update each second.

generalFunctions: e50be2e -> 43f6906
Fixes the bug where picking a supplier and then a type left the model
dropdown stuck on "Awaiting Type Selection". Affects every node that
uses the shared assetMenu (measurement, rotatingMachine, pumpingStation,
monster, …). The chained dropdowns now use an explicit downward
cascade with no synthetic change-event dispatch, so the parent handler
can no longer wipe a child after the child was populated.

measurement: d6f8af4 -> <new>
Fixes a regression in the previous measurement editor commit where a
const Temporal Dead Zone error in oneditprepare aborted the function
before the asset / logger / position menu init ran. Menus are now
kicked off first, mode logic is guarded with try/catch and null-checks.

measurement: 495b4cf -> d6f8af4
Makes Input Mode the top-level hierarchy in the editor: analog-only and
digital-only field blocks toggle visibility live based on the dropdown,
legacy nodes default to 'analog', channels JSON gets live validation,
and runtime logs an actionable warning when the payload shape doesn't
match the selected mode.
