Runtime (specificClass.js):
- Replace direction-based hysteresis with level-armed _shiftArmed state.
Arms when level rises past shiftLevel; disarms when level drops below
startLevel. While armed, ramp foot moves to startLevel and ramp top
to shiftLevel — both ends shift left, then saturate at 100 % up to
maxLevel.
- _scaleLevelToFlowPercent now takes (rampStartLevel, rampTopLevel) so
the saturation point follows the shift state.
- New setManualOutflow mirroring setManualInflow.
Adapter (nodeClass.js):
- Pipe enableShiftedRamp / shiftLevel through to control.levelbased.
- New q_out topic handler.
Editor (pumpingStation.html + new src/editor/ modules):
- Split monolithic <script> into modules: index.js (helpers),
basin-diagram.js, mode-preview.js, hover-couple.js, oneditprepare.js,
oneditsave.js — served via /pumpingStation/editor/:file.
- Mode preview redrawn per the SVG diagrams: OFF tier below 0 %, 0 %
flat from start→inlet, ramp inlet→max, optional shifted-down curve
start→shift with 100 % saturation past shift.
- Mode preview gains zone bands (dryRun / safetyLow / safe / safetyHigh /
overflow), level markers (dryRun derived, start, inlet, max, shift,
overflow), validation ribbon that blocks save on bad ordering.
- Auto-default shiftLevel to 0.9 × maxLevel on enable so the marker is
always visible.
- All level inputs moved to a side panel left of each diagram, color-
coded to match line strokes; hover-couple highlights the paired SVG
line on input focus / mouseover.
- Removed UI for non-static parameters: minHeightBasedOn,
pipelineLength, maxDischargeHead, staticHead, defaultFluid,
maxInflowRate, temperatureReferenceDegC,
timeleftToFullOrEmptyThresholdSeconds, inletPipeDiameter,
outletPipeDiameter, minLevel (now derived = dryRunLevel).
- foreignObject inputs in basin SVG removed (single source of truth in
side panel).
Dashboard example (examples/basic-dashboard.flow.json):
- Add manual Q_OUT slider + q_out builder mirroring the existing q_in
trio so the basin can be exercised end-to-end without a connected
rotating-machine downstream.
Tests (test/basic/specificClass.test.js):
- Replace direction-shift test with two new cases covering shift-disabled
hold-zone behaviour and shift-armed/disarmed transitions through
shiftLevel and startLevel boundaries. 53/53 tests pass.

### Guardrails (specificClass.js)
New _validateThresholdOrdering() runs in the constructor. Checks every
ordered pair of basin + control + derived-safety levels and logs a
warning for each violation; returns the list as this.thresholdIssues
so tests and the eval harness can inspect. Non-fatal — we prefer a
running-but-warned station to a refusal-to-start (availability-first).
Strict invariants (bottom → top):
0 < outflowLevel < inflowLevel < overflowLevel ≤ basinHeight
dryRunLevel ≤ minLevel ≤ startLevel < maxLevel ≤ overfillLevel
Uses a list-of-checks pattern rather than a switch — easier to add new
invariants without reflowing cases, and the list itself is readable
documentation.
### Bug fix (specificClass.js)
calibratePredictedLevel was writing the volume value into the LEVEL
slot. Root cause: MeasurementContainer is stateful — its type()/
variant()/position() calls mutate the container's own cursor, so
caching chain references (const levelChain = ...; const volumeChain
= ...) doesn't isolate them. The second cached chain ended up sharing
the state of the last type() call. Rebuilt chains fresh each time,
matching the calibratePredictedVolume pattern that already worked.
### Tests (test/basic/specificClass.test.js)
Ported from Jest to node:test + node:assert — the project's standard
per .claude/rules/testing.md. Deleted the stale test/specificClass.test.js
(tests referenced methods that no longer exist post-rename).
New coverage, 42 passing subtests:
- Basin geometry derivations + minHeightBasedOn
- Level/volume roundtrip
- Threshold guardrails (5 violation cases)
- Direction derivation
- Mode change accept/reject
- Calibration (volume and level paths — catches the bug above)
- Levelbased control zones (STOP / DEAD ZONE / RAMP / saturate)
- getOutput flattening
- setManualInflow
Run with: node --test test/basic/*.test.js
