# Improvements Backlog

Purpose:
- Capture functional and architectural improvements discovered during analysis runs where functionality is not changed.
- Keep an implementation queue outside active feature work.

Lifecycle:
- Add item when discovered.
- When implemented, remove the item from this file and record the fix in session notes/PR.

| ID | Date | Area | Summary | Evidence | Status |
|---|---|---|---|---|---|
| IMP-20260219-004 | 2026-02-19 | measurement editor | Label expression precedence can hide fallback label text. | `nodes/measurement/measurement.html:63` | open |
| IMP-20260219-005 | 2026-02-19 | measurement editor | `success` assigned without declaration in editor save path. | `nodes/measurement/measurement.html:131` | open |
| IMP-20260219-016 | 2026-02-19 | generalFunctions/state | `movementManager` constructor writes startup `console.log` on runtime path, adding noisy non-structured logs. | `nodes/generalFunctions/src/state/movementManager.js:16` | open |
| IMP-20260219-018 | 2026-02-19 | generalFunctions/helper | Legacy menu endpoint still uses generated class source (`menuUtils.legacy.js`) as compatibility fallback; plan removal after UI validation of stable bootstrap/data path. | `nodes/generalFunctions/src/helper/endpointUtils.js:113`, `nodes/generalFunctions/src/helper/menuUtils.js:575` | open |
| IMP-20260219-019 | 2026-02-19 | generalFunctions/menu | `menuUtils.js` embeds extensive runtime `console.*` and inline API/debug logging in generated client scripts, increasing noise and making prod diagnostics harder. | `nodes/generalFunctions/src/helper/menuUtils.js:35` | open |
| IMP-20260219-020 | 2026-02-19 | generalFunctions/predict | `interpolation.js` contains raw runtime debug log (`console.log(this.interpolationtype)`), leaking internal state in production paths. | `nodes/generalFunctions/src/predict/interpolation.js:127` | open |
| IMP-20260219-021 | 2026-02-19 | generalFunctions/menu | Two active menu utility implementations (`menuUtils.js` and `menuUtils_DEPRECATED.js`) still coexist, increasing drift risk and maintenance overhead. | `nodes/generalFunctions/src/helper/menuUtils.js:1`, `nodes/generalFunctions/src/helper/menuUtils_DEPRECATED.js:1` | open |
| IMP-20260219-022 | 2026-02-19 | generalFunctions/outliers | `DynamicClusterDeviation.update()` emits verbose `console.log` traces on each call with no log-level guard, unsafe for production telemetry volume. | `nodes/generalFunctions/src/outliers/outlierDetection.js:7` | open |
| IMP-20260224-006 | 2026-02-24 | rotatingMachine prediction fallback | When only one pressure side is available, predictor uses absolute pressure as surrogate differential, which can materially bias flow prediction under varying suction/discharge conditions. | `nodes/rotatingMachine/src/specificClass.js:573`, `nodes/rotatingMachine/src/specificClass.js:588` | open |
| IMP-20260224-012 | 2026-02-24 | cross-node unit architecture | Canonical unit-anchor strategy is implemented in rotatingMachine plus phase-1 controllers (`machineGroupControl`, `pumpingStation`, `valve`, `valveGroupControl`); continue rollout to remaining nodes so all runtime paths use canonical storage + explicit ingress/egress units. | `nodes/machineGroupControl/src/specificClass.js:42`, `nodes/pumpingStation/src/specificClass.js:48`, `nodes/valve/src/specificClass.js:87`, `nodes/valveGroupControl/src/specificClass.js:78` | open |
