No production consumer; deprecated since the MeasurementContainer-based
event surface landed. Drops the on-emit subscription that bridged the
analog channel's <type>.measured.<position> event to source.emitter
as 'mAbs'. 96/96 tests pass.

Runtime:
- Fix silent no-op when user selected any camelCase smoothing or outlier
method from the editor. validateEnum in generalFunctions lowercases enum
values (zScore -> zscore, lowPass -> lowpass, ...) but the dispatcher
compared against camelCase keys. Effect: 5 of 11 smoothing methods
(lowPass, highPass, weightedMovingAverage, bandPass, savitzkyGolay) and
2 of 3 outlier methods (zScore, modifiedZScore) silently fell through.
Users got the raw last value or no outlier filtering with no error log.
Review any pre-2026-04-13 flows that relied on these methods.
Fix: normalize method names to lowercase on both sides of the lookup.
- New Channel class (src/channel.js) — self-contained per-channel pipeline:
outlier -> offset -> scaling -> smoothing -> min/max -> constrain -> emit.
Pure domain logic, no Node-RED deps, reusable by future nodes that need
the same signal-conditioning chain.
Digital mode:
- config.mode.current = 'digital' opts in. config.channels declares one
entry per expected JSON key; each channel has its own type, position,
unit, distance, and optional scaling/smoothing/outlierDetection blocks
that override the top-level analog-mode fields. One MQTT-shaped payload
({t:22.5, h:45, p:1013}) dispatches N independent pipelines and emits N
MeasurementContainer slots from a single input message.
- Backward compatible: absent mode config = analog = pre-digital behaviour.
Every existing measurement flow keeps working unchanged.
UI:
- HTML editor: new Mode dropdown and Channels JSON textarea. The Node-RED
help panel is rewritten end-to-end with topic reference, port contracts,
per-mode configuration, smoothing/outlier method tables, and a note
about the pre-fix behaviour.
- README.md rewritten (was a one-line stub).
Tests (12 -> 71, all green):
- test/basic/smoothing-methods.basic.test.js (+16): every smoothing method
including the formerly-broken camelCase ones.
- test/basic/outlier-detection.basic.test.js (+10): every outlier method,
fall-through, toggle.
- test/basic/scaling-and-interpolation.basic.test.js (+10): offset,
interpolateLinear, constrain, handleScaling edge cases, min/max
tracking, updateOutputPercent fallback, updateOutputAbs emit dedup.
- test/basic/calibration-and-stability.basic.test.js (+11): calibrate
(stable and unstable), isStable, evaluateRepeatability refusals,
toggleSimulation, tick simulation on/off.
- test/integration/digital-mode.integration.test.js (+12): channel build
(including malformed entries), payload dispatch, multi-channel emit,
unknown keys, per-channel scaling/smoothing/outlier, empty channels,
non-numeric value rejection, getDigitalOutput shape, analog-default
back-compat.
E2E verified on Dockerized Node-RED: analog regression unchanged; digital
mode deploys with three channels, dispatches MQTT-style payload, emits
per-channel events, accumulates per-channel smoothing, ignores unknown
keys.
Depends on generalFunctions commit e50be2e (permissive unit check +
mode/channels schema).
