From e058fe92450cf7caceba7e4b2b8c3ede5d293f6d Mon Sep 17 00:00:00 2001 From: znetsixe Date: Sun, 10 May 2026 22:00:34 +0200 Subject: [PATCH] P5 wave 2: convert rotatingMachine to BaseDomain + extract helper modules MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit specificClass.js: 1760 → 400 lines. Machine extends BaseDomain. configure() wires curves + predictors + drift + pressure + state bindings + measurement handlers + flow controller. ChildRouter handles pressure/flow/power/temperature measurement events; custom registerChild override preserves the dedup + virtual-vs-real pressure tracking the integration tests pin. Added small host-aware helper modules to fit the 400-line cap: src/prediction/predictionMath.js (calcFlow/Power/Ctrl) src/prediction/efficiencyMath.js (calcCog/EfficiencyCurve/etc.) src/pressure/pressureSelector.js (getMeasuredPressure source preference) src/state/sequenceController.js (executeSequence/setpoint/wait helpers) src/measurement/childRegistrar.js (custom registerChild path) src/drift/healthRefresh.js (drift status update wrappers) src/io/output.js (buildOutput + buildStatusBadge) unitPolicy: live UnitPolicy methods .canonical()/.output()/.curve() bridged to legacy property-path readers via a frozen view object — same pattern as MGC. See OPEN_QUESTIONS.md. nodeClass.js: 433 → 61 lines. Extends BaseNodeAdapter. tickInterval=null (event-driven on state + measurement events). buildDomainConfig stamps the rotatingMachine state + errorMetrics slices on the domain config so configure() builds them from there. 5 tests adjusted (4 nodeClass-config, 1 error-paths) — pre-refactor they pinned private methods (_loadConfig, _setupSpecificClass, _attachInputHandler, _updateNodeStatus) that no longer exist. New versions drive the public BaseNodeAdapter surface or call extracted io/state-machine helpers directly. See OPEN_QUESTIONS.md 2026-05-10 "private nodeClass tests" for the deferred rewrite plan. 196 / 196 tests pass (basic 110 + integration ~80 + edge ~6).
