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).

Each fixture's machineConfig() now passes asset: { model, unit } only —
the supplier / category / type strings are derived at runtime via
assetResolver in rotatingMachine's _setupCurves. Six integration tests
updated. No behaviour change.

- Fix flowmovement unit mismatch: MGC computed flow in canonical (m³/s)
but rotatingMachine expects output units (m³/h). All flowmovement calls
now convert via _canonicalToOutputFlow(). Without this fix, every pump
stayed at minimum flow regardless of demand.
- Fix absolute scaling: demandQout vs demandQ comparison bug, reorder
conditions so <= 0 is checked first, add else branch for valid demand.
- Fix empty Qd <= 0 block: now calls turnOffAllMachines().
- Add empty-machines guards on optimalControl and equalizePressure.
- Add null fallback (|| 0) on pressure measurement reads.
- Fix division-by-zero in calcRelativeDistanceFromPeak.
- Fix missing flowmovement after startup in equalFlowControl.
- Add marginal-cost refinement loop in BEP-Gravitation: after slope-based
redistribution, iteratively shifts flow from highest actual dP/dQ to
lowest using real power evaluations. Closes gap to brute-force optimum
from 2.1% to <0.1% without affecting combination selection stability.
- Add NCog distribution comparison tests and brute-force power table test.
