mgc.html: sidebar swatch → #B5651D (mid-orange, rotating-machinery family) as part of the EVOLV palette redesign 2026-05-21. See superproject .claude/rules/node-red-flow-layout.md §10.0 and .claude/refactor/OPEN_QUESTIONS.md.
src/editor/compact-fields.js: minor field tweak (separate, in-progress work).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* compact-fields.js (new): trimmed to MGC-only output-format pickers
(processOutputFormat / dbaseOutputFormat). The logger toggle/level
and physical-position visuals now come from generalFunctions'
shared iconHelpers, auto-injected via /machineGroupControl/menu.js.
* mode-cards.js: strategy cards re-styled — Most-efficient (BEP bell
with dot on the curve peak), Priority (clean staircase), Maintenance
(Font Awesome fa-wrench). Rendezvous toggle flips Active / Inactive
label dynamically.
* mgc.html: dropped the duplicated .mgc-icon-* CSS rules (now live in
the shared iconHelpers stylesheet). Strategy + rendezvous CSS stays
local (MGC-specific). Output picker holders switched to the shared
.evolv-icon-picker class.

Routes every dispatch through a tick-aware planner so all pumps reach
their setpoint at the same wall-clock instant t* = max(eta_i),
regardless of control strategy or per-pump reaction speed.
Architecture (src/movement/):
- machineProfile.js – pure snapshot of a registered child (state,
position, velocityPctPerS, ladder timings,
flowAt / positionForFlow). Reads timings from
child.state.config.time (the actual storage
location — previous fallback paths silently
produced 0 s, collapsing every eta to ramp-only).
- moveTrajectory.js – seconds-to-target per machine; handles
idle / starting / warmingup / operational / cooling.
- movementScheduler.js – t* = max eta over ALL non-noop moves. Every
command is delayed so its move finishes at t*.
Startup execsequence fires at 0; its flowmovement
is gated by max(ladderS, t* − rampS) so a fast
pump waits before ramping rather than landing
early. useRendezvous=false collapses to all
fireAtTickN=0 (legacy fire-and-forget).
- movementExecutor.js – wall-clock virtual cursor: each tick fires
every command whose fireAtTickN ≤ floor(elapsed/tickS).
tick() no longer awaits pending fireCommand
promises — the synchronous prologue of
handleInput claims the latest-wins gate, which
is what race-favouring relies on.
Shared dispatch path (src/specificClass.js):
- _dispatchFlowDistribution(distribution) — extracted from
_optimalControl. Builds profiles, calls movementScheduler.plan,
replans the executor, ticks once. Reads
config.planner.useRendezvous (default true).
- _optimalControl computes its bestCombination and hands off.
- equalFlowControl (priorityControl mode) computes its
flowDistribution and hands off via ctx.mgc._dispatchFlowDistribution.
Same-time landing now applies in BOTH modes.
Editor toggle (mgc.html + src/nodeClass.js):
- New "Same-time landing" checkbox under Control Strategy.
- nodeClass.buildDomainConfig bridges uiConfig.useRendezvous →
config.planner.useRendezvous. Default ON.
Tests:
- New: planner-convergence.integration.test.js (real-time end-to-end
diagnostic — drives a 3-pump mixed-state dispatch and asserts both
convergence to the demand setpoint AND same-time landing within
one tick).
- New: planner-rendezvous.integration.test.js (schedule-shape
assertions against real pump objects).
- New: movementScheduler.basic.test.js — includes a mixed-speed
multi-startup case proving the fast pumps wait so all three land
together (the regression that prompted this work).
- New: movementExecutor.basic.test.js + moveTrajectory.basic.test.js.
- Updated executor contract test: tick() must NOT await pending fires.
Commands + wiki:
- handlers.js: source/mode allow-list gate moved into a shared _gate()
helper; every command now checks isValidActionForMode +
isValidSourceForMode before dispatching. Status-level commands
(set.mode, set.scaling) are allowed in every mode.
- commands.basic.test.js: coverage for the new gate behaviour.
- wiki regen: Home.md visual-first rewrite + Reference-{Architecture,
Contracts,Examples,Limitations}.md split with _Sidebar.md index.

Two governance items from the 2026-05-14 quality review:
- test/_output-manifest.md enumerates every Port 0/1/2 key MGC emits, its
source, type, range, and which tests cover it in populated/degraded states
(per .claude/rules/output-coverage.md).
- src/control/strategies.js extracts computeEqualFlowDistribution as a pure
function so the equal-flow algorithm is testable without an MGC fixture.
test/basic/equalFlowDistribution.basic.test.js (6 tests) covers all three
demand branches and pins the legacy quirk where the default branch counts
active machines but iterates priority-ordered first-N (documented in the
test so the future cleanup is a deliberate change).
Plus rolled-up session work that landed alongside:
- set.demand is now unit-self-describing ({value, unit:'m3/h'|'l/s'|'%'|...}
or bare number = %); setScaling/scaling.current removed from MGC, commands,
editor (mgc.html), specificClass.
- _optimalControl + equalFlowControl now compute eta = (Q*dP)/P_shaft rather
than Q/P, keeping the metric in the same scale as each child's cog.
- groupEfficiency.calcRelativeDistanceFromPeak returns undefined (was 1) when
pumps are homogeneous (|max-min| < 1e-9). Dashboard treats undefined as
'-' instead of showing a misleading 100% / 0% reading.
- examples/02-Dashboard.json: auto-init inject so the dashboard populates at
deploy, NCog formatter normalizes the SUM emitted by MGC by
machineCountActive, Q-H fanout trims the flat-Q tail so the H axis isn't
stretched to 40m by curve-envelope clamp points, num/pct treat null AND
undefined as no-data (closes the +null === 0 trap).
- new test/integration/dashboard-fanout.integration.test.js (17 tests),
bep-distance-demand-sweep.integration.test.js (3 tests),
group-bep-cascade.integration.test.js -- total suite now 108/108 green.
- .gitignore: wiki/test.gif (143 MB screen recording, kept locally only).

Editor (mgc.html)
- Drag-in defaults now expose mode (optimalControl) and scaling (normalized)
via dropdowns in the edit dialog. Was: no control fields in the UI at all,
so users had to send set.mode/set.scaling after deploy or live with the
hidden schema defaults.
Wire-up (src/nodeClass.js)
- buildDomainConfig now bridges the flat editor fields (mode, scaling) into
the nested schema shape (mode.current, scaling.current). Was: returned {}
so the editor's mode/scaling never reached the runtime.
Mode-case bug fix (src/specificClass.js)
- Schema enum values are camelCase (optimalControl, priorityControl) but the
runtime switch in _runDispatch matched lowercase only. With the default
config, dispatch silently fell through to the warning branch and nothing
ran. Normalise via String(this.mode).toLowerCase() so both forms work.
Status badge (src/io/output.js)
- Compacted from ~80 chars (mode | Ⓝ: 💨=Q/Qmax | ⚡=P | N machine(s)) to
~50 chars (mode | norm | Q=Q/Qmax m³/h | P=P kW | active/total x).
Drops emoji glyphs that rendered inconsistently across themes; uses the
same dot+fill convention as pumpingStation.
Output extension (src/io/output.js)
- getOutput() now also emits flowCapacityMin/Max, machineCount,
machineCountActive. Was: only group-level totals + dist-from-peak +
mode/scaling, so dashboards couldn't show capacity / active count
without subscribing to each rotatingMachine individually.
Examples
- Drop pre-refactor stubs (basic.flow.json, integration.flow.json,
edge.flow.json). They had a single MGC + inject + debug, no children,
and never dispatched anything.
- 01-Basic.json: 1 MGC + 3 rotatingMachine pumps + Setup once-fires
virtualControl + cmd.startup on all pumps via fan-out function. Numbered
driver groups for Control mode / Scaling / Operator demand. Pumps
register with MGC via Port 2 (child.register, automatic).
- 02-Dashboard.json: same plumbing + FlowFuse Dashboard 2.0 page with
Controls (mode + scaling buttons, demand slider 0–100, stop + init
buttons), Status (7 ui-text rows), Trends (3 charts: flow + capacity,
power, BEP rel %), and a raw-output ui-template dumping every Port 0
field. Fan-out function caches last-known values so deltas don't blank.
Wiki + README
- examples/README.md rewritten for the two-file set with canonical command
surface table and "what to try" recipes.
- wiki/Home.md §11 (Examples) updated; §14 #4 (TODO flow item) replaced
with the actual current limitation (no per-pump fan-out on Port 0).

### Bug fix — stale flow cache on shutdown (specificClass.js)
When turnOffAllMachines() fires (negative demand, zero flow demand, or
safety trip), the MGC was only shutting pumps down. The pumps' last
emitted predicted flow / power stayed in the MeasurementContainer,
so the parent pumpingStation kept computing net flow from cached
non-zero values — reading the MGC as "still draining" when it wasn't.
Net: net-flow direction and safety triggers misfired during and
shortly after an MGC shutdown.
Fix: after shutting down all machines, write 0 to the predicted
flow (downstream + atEquipment) and predicted power (atEquipment)
slots so the cache reflects reality immediately.
### Correctness — async/await on shutdown (specificClass.js)
Two call sites invoked turnOffAllMachines() without awaiting it, so
the subsequent `return` raced the shutdown promises. Now awaited.
Also DRY'd one inline shutdown loop into a call to
turnOffAllMachines().
### Physics correction — NCog for centrifugal pumps (integration tests)
The previous tests asserted NCog > 0 for centrifugal pumps. That's
physically wrong: for variable-speed centrifugal pumps P ∝ n³ and
Q ∝ n, so Q/P ∝ 1/n² is monotonically decreasing with speed. Peak
efficiency (peak Q/P) is always at minimum speed → cogIndex = 0 →
NCog = 0 by the current formula.
Tests now:
- Assert NCog == 0 for all centrifugal configurations
- Assert distributeByNCog() falls back to equal distribution when
NCog == 0 (confirmed by the existing tests 4-6 that slope-based
redistribution is what actually differentiates pumps with different
BEPs — not NCog)
This matches the actual implementation; the previous tests were
asserting an idealised COG model that doesn't apply here.
### Editor hygiene (mgc.html, nodeClass.js)
- mgc.html: add missing asset-menu defaults (uuid, supplier, category,
assetType, model, unit) — brings MGC in line with rotatingMachine
and pumpingStation editor shapes.
- nodeClass.js: clear node status badge on close.
All 13 tests (basic + integration) pass.
