# Top 10 Production Priorities (Round 2, Availability-First)

Context:
- Generated after implementing the first top-10 and follow-up items `IMP-20260219-011/012/013`.
- Focus remains: keep runtime up, prefer degraded/null outputs over hard failures.

## Priority List

1. Fix measurement outlier toggle corruption.
- Why: toggling replaces the outlier config object with a boolean, breaking later config reads.
- Evidence: `nodes/measurement/src/specificClass.js:509`.

2. Fix rotating machine pressure-difference unit request API mismatch.
- Why: `difference('Pa')` no longer matches container API; requested unit is ignored, risking incorrect efficiency basis.
- Evidence: `nodes/rotatingMachine/src/specificClass.js:856`, `nodes/generalFunctions/src/measurements/MeasurementContainer.js:436`.

3. Guard reactor PFR state indexing at boundary conditions.
- Why: known edge behavior can overrun index mapping near exact reactor length and destabilize updates.
- Evidence: `nodes/reactor/src/specificClass.js:326`.

4. Make dashboard template resolution fail-soft.
- Why: missing template currently throws and aborts dashboard generation path.
- Evidence: `nodes/dashboardAPI/src/specificClass.js:91`.

5. Make dashboard input path skip invalid children instead of throwing.
- Why: missing child source/config currently throws; should warn and continue in availability-first mode.
- Evidence: `nodes/dashboardAPI/src/nodeClass.js:55`.

6. Harden shared config merge semantics for arrays/types.
- Why: recursive merge mutates destination and treats arrays as objects, risking config drift.
- Evidence: `nodes/generalFunctions/src/helper/configUtils.js:77`.

7. Fix machineGroupControl child position source path.
- Why: reads `positionVsParent` from `general` instead of `functionality`, causing inconsistent routing metadata.
- Evidence: `nodes/machineGroupControl/src/specificClass.js:53`.

8. Accept numeric-string measurement payloads safely.
- Why: measurement node currently ignores numeric strings common in PLC/edge integrations.
- Evidence: `nodes/measurement/src/nodeClass.js:167`.

9. Fix reactor editor save wiring mismatch.
- Why: editor save hook references the wrong node helpers, risking mis-saved position settings.
- Evidence: `nodes/reactor/reactor.html:133`.

10. Replace raw `structuredClone` usage with compatibility-safe clone strategy.
- Why: runtime portability risk across constrained Node-RED deployments.
- Evidence: `nodes/settler/src/specificClass.js:34`, `nodes/settler/src/specificClass.js:45`.

## Implementation Status

- Implemented on 2026-02-19 in current session.
- Verification: tests passed for `generalFunctions`, `measurement`, `reactor`, `rotatingMachine`, `dashboardAPI`, `machineGroupControl`, `settler`, `pumpingStation`, `valve`, `valveGroupControl`, `monster`.
- Follow-up architectural items are tracked in `.agents/improvements/IMPROVEMENTS_BACKLOG.md`.
