Basin undersized (10m³) for sinus peak (126 m³/h) → overflow → 122%.
Now 30 m³ with 4m height, all PS fields set. New rule: always configure
every field of every node.

Charts rendered blank because the helper was missing 15+ required
FlowFuse properties. The critical three:
- interpolation: "linear" (no line drawn without it)
- yAxisProperty: "payload" + yAxisPropertyType: "msg" (chart didn't
know which msg field to plot)
- xAxisPropertyType: "timestamp" (chart didn't know the x source)
Also: width/height must be numbers not strings, colors/textColor/
gridColor arrays must be present, and stackSeries/bins/xAxisFormat/
xAxisFormatType all need explicit values.
Fixed the ui_chart helper to include every property from the working
rotatingMachine/examples/03-Dashboard.json charts. Added the full
required-property template + gotcha list to the flow-layout rule set
(Section 4) so this class of bug is caught by reference on the next
chart build.

Sections 10-16 extend the existing flow-layout rule with a deterministic
lane-and-group convention anchored in the S88 hierarchy:
- 8 logical lanes: L0 inputs -> L1 adapters -> L2 CM -> L3 EM -> L4 UN
-> L5 PC -> L6 formatters -> L7 outputs. 240 px between lanes.
- Lane assignment is by S88 level, not by node name. New nodes inherit
a lane via a NODE_LEVEL registry, no rule change needed.
- Every parent + its direct children is wrapped in a Node-RED group box
coloured by the parent's S88 level (Pump A = EM blue, MGC = Unit blue,
PS = Process Cell blue, ...). Search the parent's name -> group
highlights.
- Utility clusters (mode broadcast, station-wide commands, demand
fan-out) use neutral-grey group boxes.
- Dashboard / setup / demo-driver tabs each get a variant of the rule.
- Spacing constants, place() and wrap_in_group() helpers, an 8-step
verification checklist.
Off-spec colours (settler orange, monster teal, diffuser and
dashboardAPI missing) are flagged in Section 16 as a follow-up cleanup.
The NODE_LEVEL registry already maps those nodes to their semantic S88
level regardless of what the node's own colour currently says.
Rule lives in the superproject only; per-node repos will reference it
from their own CLAUDE.md files (separate commits per submodule).

The demo was a single 96-node tab with everything wired directly. Now
4 tabs wired only through named link-out / link-in pairs, and a
permanent rule set for future Claude sessions to follow.
Tabs (by concern, not by data flow):
🏭 Process Plant only EVOLV nodes (3 pumps + MGC + PS + 6 measurements)
+ per-node output formatters
📊 Dashboard UI only ui-* widgets, button/setpoint wrappers, trend
splitters
🎛️ Demo Drivers random demand generator + state holder. Removable
in production
⚙️ Setup & Init one-shot deploy-time injects (mode, scaling,
auto-startup, random-on)
Cross-tab wiring uses a fixed named-channel contract (cmd:demand,
cmd:mode, cmd:setpoint-A, evt:pump-A, etc.) — multiple emitters can
target a single link-in for fan-in, e.g. both the slider and the random
generator feed cmd:demand.
Bug fixes folded in:
1. Trend chart was empty / scrambled. Root cause: the trend-feeder
function had ONE output that wired to BOTH flow and power charts,
so each chart received both flow and power msgs and the legend
garbled. Now: 2 outputs (flow → flow chart, power → power chart),
one msg per output.
2. Every ui-text and ui-chart fell on the (0, 0) corner of the editor
canvas. Root cause: the helper functions accepted x/y parameters
but never assigned them on the returned node dict — Node-RED
defaulted every widget to (0, 0) and they piled on top of each
other. The dashboard render was unaffected (it lays out by group/
order), but the editor was unreadable. Fixed both helpers and added
a verification step ("no node should be at (0, 0)") to the rule set.
Spacing convention (now codified):
- 6 lanes per tab at x = [120, 380, 640, 900, 1160, 1420]
- 80 px standard row pitch, 30-40 px for tight ui-text stacks
- 200 px gap between sections, with a comment header per section
New rule set: .claude/rules/node-red-flow-layout.md
- Tab boundaries by concern
- Link-channel naming convention (cmd:/evt:/setup: prefixes)
- Spacing constants
- Trend-split chart pattern
- Inject node payload typing pitfall (per-prop v/vt)
- Dashboard widget rules (every ui-* needs x/y!)
- Do/don't checklist
- Link-out/link-in JSON cheat sheet
- 5-step layout verification before declaring a flow done
CLAUDE.md updated to point at the new rule set.
Verified end-to-end on Dockerized Node-RED 2026-04-13: 168 nodes across
4 tabs, all wired via 22 link-out / 19 link-in pairs, no nodes at
(0, 0), pumps reach operational ~5 s after deploy, MGC distributes
random demand, trends populate per pump.
