levelBased ramp + engagement:
- Ramp foot is now max(startLevel, holdLevel) — was max(startLevel,
inflowLevel). inflowLevel is basin geometry, not a control setpoint;
the implicit hold zone it created was causing pumps to "start at
inflowLevel" instead of startLevel.
- New optional `holdLevel` config (defaults to startLevel = no hold band).
When raised, pumps engage at startLevel and hold at 0 % = MGC flow.min
across [startLevel, holdLevel], then ramp 0..100 % to maxLevel.
- Engagement decided in run() (not in `_applyMachineGroupLevelControl`):
rising-edge hysteresis arming gates a clean turnOff early-return.
Once armed, the helper always forwards setDemand(pct, '%') — 0 %
legitimately means "engaged at min flow", no more soft-turnOff at
the boundary.
- Disengagement paths (minLevel hard-stop, stopLevel falling-edge,
pre-arming idle) now all clear the shifted-ramp hysteresis state too.
- Threshold validator drops the startLevel ≤ inflowLevel rule; adds
startLevel ≤ holdLevel < maxLevel (only checked when holdLevel is
explicitly set, so default-null doesn't false-flag).
MGC unit math:
- Replace direct group.handleInput(percent) with group.setDemand(pct, '%')
in _applyMachineGroupLevelControl. The percent → m³/s resolution now
lives in MGC.setDemand (committed separately in the MGC submodule).
FlowAggregator variant picking:
- New _pickFlowSum() helper mirrors selectBestNetFlow's variant
precedence (measured first, then predicted) and resolves each side
independently. Realistic mixed case — real measured upstream sensor +
predicted pump outflow — now feeds the predicted-volume integrator.
Was reading only `flow.predicted.*` so a real upstream sensor
(which writes `flow.measured.*`) never moved the level.
Editor:
- New `holdLevel` and `deadZoneKeepAlivePercent` defaults + side-panel
input rows in the levelbased mode preview.
- Add the missing `ps-mode-line-holdLevel` SVG marker (was declared in
the side-panel coupling but the SVG element didn't exist, so the
dashed line never rendered).
- Relax stopLevel marker gate so it renders for any non-negative typed
value — start/stop ordering is the ribbon's job, not the marker's
(was hiding the line whenever startLevel was momentarily smaller).
- Add holdLevel to the marker loop in mode-preview so changes track.
- Add stopLevel + holdLevel + maxLevel to all three bindRedraw lists
(basin-diagram, mode-preview, bounds.apply) so the SVG, validation
ribbon, and HTML5 min/max attrs update on every edit.
- Initialise stopLevel + holdLevel + deadZoneKeepAlivePercent inputs
in oneditprepare so reopening the editor shows the saved values.
- nodeClass passes holdLevel + deadZoneKeepAlivePercent into the
domain config.
Tests:
- New test/basic/_probe_upstream_emit.test.js: confirms the parent
surfaces flow.measured.upstream.* on Port 0 after a measurement
child write — pins the previously-invisible measured variant flow.
- flowAggregator.basic.test.js: two new regression cases — measured
inflow when predicted side is empty, and the measured-in /
predicted-out mixed case.
- control-levelBased.basic.test.js: new cases for the holdLevel hold
band, the [stopLevel, startLevel] keep-alive, the engagement gate,
and the "0 % at startLevel = setDemand" contract.
- specificClass.test.js: zone tests adjusted to the new ramp foot.
Shifted-ramp tests pin holdLevel = 3 explicitly so their legacy
arithmetic (ramp foot at inflowLevel) stays self-consistent.
- shifted-ramp-end-to-end.test.js: same holdLevel pin for the same
reason.
Packaging:
- Add .gitignore + .npmignore so the published tarball drops the
wiki/, simulations/, test/, tools/, .claude/ etc. The pack went
from 1.5 MB (72 files) to ~57 KB (30 files).

Levelbased control now distinguishes startLevel (rising-edge engage,
ramp foot) from stopLevel (falling-edge disengage). _stopHystRunning
flag flips TRUE crossing startLevel up, FALSE crossing stopLevel down.
While engaged AND level inside [stopLevel, startLevel] (basin draining
through the dead band), emit a configurable keep-alive percControl
(default 1 %) so MGC keeps a single pump running for a full drain
stroke instead of oscillating at startLevel.
Hard turn-off the moment level <= stopLevel — independent of ramp
scaling. Manual-mode demand=0 now also issues explicit turnOff to
keep parity with the new MGC handleInput semantics where demand<=0
means "off".
Editor preview shades the new hysteresis band; admin endpoint
exposes runtime engaged state.

Bounds (new src/editor/bounds.js):
- Sets HTML5 min/max on every level + percent input each redraw,
derived from the current values of related inputs so the spinner
stops at the basin hierarchy:
0 < outflowLevel < dryRunLevel < startLevel ≤ inflowLevel
≤ shiftLevel ≤ maxLevel ≤ overflowLevel ≤ basinHeight
- dryRunPercent capped so dryRunLevel ≤ startLevel given current outflow.
- shiftArmPercent ∈ [1, 100]; highVolumeSafety% ∈ [1, 100].
Validation:
- New visible ribbon above the basin diagram (#ps-basin-validation)
listing every hierarchy violation. The in-SVG warning text is now a
small reminder ("⚠ N ordering issues").
- basin-diagram.js owns hierarchy issues; mode-preview.js trimmed to
only own shift-specific issues (shift > start, shift ≤ max,
shiftArmPercent range, shiftLevel required-when-enabled).
- oneditsave blocks Deploy on the union of _psBasinValidationIssues
and _psModeValidationIssues with a RED.notify listing all problems.
Layout polish:
- Side panel widened to 220 px with minmax(0, 1fr) first column so long
labels can no longer push the rows past the panel edge.
- Basin SVG max-width 380 → 360, gap between side panel and SVG bumped
14 → 28 px. Tank shifted right (x=145 width=110) so the inlet
"bottom of pipe" sub-label is no longer clipped on the left edge.
- "0 m (datum)" moved below the tank (y=395, centred) so it can't
collide with "Outlet / top of pipe" when outflowLevel is near floor.
- Zone labels shortened (Spare / Sewage + buffer / Buffer / Dead vol)
and only show when the bracketing thresholds are ≥ 28 px apart, so
they never sit on a threshold label.
- Mode preview axis labels under the chart removed — line colour +
side-panel labels + hover-couple already identify each line. Stub
<text> elements left hidden to keep the redraw loop simple. Arm-%
line + label trimmed in 10 px on the right so they're not clipped.
