Once a rendezvous plan is committed it now runs to completion untouched: an
ordinary new setpoint arriving while the group is 'working' is remembered
(latest wins) and dispatched sequentially when the group reaches 'ready',
instead of aborting + re-planning. A re-plan mid-flight dropped the in-flight
schedule and re-deferred a pump that was mid-sequence, parking starting pumps
at minimum flow.
Only an EMERGENCY pre-empts the lock: a stop (≤0) or a pressure excursion.
_isUrgentDemand (which pre-empted on any large step) is replaced by
_isEmergencyDemand; the large-step pre-emption is gone — large operator steps
now defer like any other setpoint. _pressureEmergency() reads
planner.emergencyPressurePa and is INERT until that threshold is configured;
handlePressureChange fires a latched bypass dispatch when it breaches.
Verified live on the E2E Isolated MGC rig: a 1→2 pump staging transition ramps
the added pump straight through (no wait-at-minimum, no start-then-stop) and the
group total climbs monotonically. (The Pump-tab node's hunting is a separate
demand-feedback-loop issue in that flow's wiring, not the rendezvous.)
Integration tests now settle to 'ready' between demands (waitReady) since the
lock defers setpoints arriving mid-move.

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).
