PALETTE REDESIGN (2026-05-21)
Sidebar swatches switched from S88 level (all blue) to domain-hue per node.
Family hue = function (rotating=orange, valves=teal, biology=green/olive,
sampling=violet, sensor=amber, aeration=sky-blue, infrastructure=slate);
within a family, darker = higher S88 / "more controller-ish."
Editor-group rectangles in flow.json still follow S88 — only the
registerType colour changed.
Submodule bumps for palette: rotatingMachine, machineGroupControl,
pumpingStation, valve, valveGroupControl, reactor, settler, monster,
measurement, diffuser, dashboardAPI.
Docs touched:
- CLAUDE.md: palette swatch vs. editor-group bullets split out.
- .claude/rules/node-red-flow-layout.md: new §10.0 introduces the two
color systems, full 12-row palette table, and explicit warning not to
mix the two hexes.
- .claude/refactor/MODULE_SPLIT.md: per-node headers annotated with
both `group #XXX` and `palette #XXX`.
- .claude/refactor/WIKI_HOME_TEMPLATE.md + WIKI_TEMPLATE.md: clarify
Mermaid classDefs visualize hierarchy, not palette swatches.
- .claude/refactor/OPEN_QUESTIONS.md: dated decision entry with
rationale, file list, and follow-ups.
CORESYNC SUBMODULE (new)
nodes/coresync added pointing at https://gitea.wbd-rd.nl/RnD/coresync.
FROST/SensorThings handoff path — first version forwards FROST-ready HTTP
request messages on the dbase output; a downstream http-request node
performs the POST and feeds responses back on msg.topic = "frost.response".
Lazy stream resolver, latest-wins queue (keep first + latest, drop middle),
knot-emit on slope change, provenance preserved in Observation parameters.
- .gitmodules: add nodes/coresync entry.
- package.json: register coresync as a Node-RED node.
- generalFunctions bump: new frostFormatter + 4 node config schemas
expose the dbase format option.
- measurement bump: "frost" option added to dbaseOutputFormat dropdown
(plus the in-flight data.measurement unit-handling work).
- machineGroupControl bump: small editor compact-fields tweak alongside
the palette change.
- CORESYNC_FROST_INTERVIEW_HANDOFF.md added at root with interview state
(Q20 open: slope angle vs. relative delta comparison).
DASHBOARDAPI MODULE_NOT_FOUND FIX
package.json: dashboardapi entry path corrected to
nodes/dashboardAPI/dashboardAPI.js. Commit e04c4a1 renamed the files to
camelCase but missed package.json; on case-sensitive filesystems
(Linux/Docker, where the tarball lands) the require resolved to nothing
and the node showed MODULE_NOT_FOUND in the Node-RED palette.
MISC CLEANUP
- examples/README.md + examples/pumpingstation-complete-example/ removal
(build_flow.py, flow.json, README.md superseded by per-node examples).
- jest.config.js: in-progress tweak.

Submodule bumps land the deadlock fix (state.js residue unpark + MGC
optimalControl dispatch reorder) and pumpingStation stopLevel hysteresis.
- Renames examples/pumpingstation-3pumps-dashboard →
pumpingstation-complete-example with regenerated flow.json. New
dashboard groups, demand-broadcast wiring, S88 placement rule
applied, ui-chart trend-split and link-channel naming follow
.claude/rules/node-red-flow-layout.md.
- New cross-node test harness under test/: end-to-end-pumpingstation
drives PS + MGC + 3 pumps + physics simulator end-to-end and
verifies the ~5/15 min cycle.
- Adds Grafana provisioning dashboards (pumping-station.json) and a
helper sync-example.sh script for export/import to live Node-RED.
- Docker entrypoint + settings + compose tweaks for the persistent
user dir layout used by the demo.

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.
