## 6) End-to-End Execution Flow
1. Node registration instantiates `nodeClass`, then `Specific` (`Machine`).
2. `Machine` constructor loads model curve, initializes predictors/state/measurements, creates virtual pressure children, and subscribes to state events.
3. `nodeClass` starts delayed child registration (`output 2`) and 1-second tick/status loops.
4. Incoming topics route through `switch(msg.topic)` to mode changes, movement/sequence commands, child registration, and simulated measurements.
5. Child measurement events update parent measurement container and dispatch typed handlers.
6. Pressure updates set predictor dimension, recompute flow/power/efficiency/CoG/BEP metrics.
7. Each tick emits formatted process + influx messages.

## 8) Calculations and Capability Matrix
- **Curve-backed capabilities**:
  - flow prediction (`nq`) via `predictFlow`
  - power prediction (`np`) via `predictPower`
  - control inversion (flow->ctrl) via reversed `nq`
- **Pressure basis selection order**:
  1. real differential (`downstream - upstream`)
  2. real/virtual downstream only
  3. real/virtual upstream only
  4. fallback `0` (minimum pressure behavior)
- **Availability-first behavior**:
  - missing pressure does not stop operation; it degrades predictions and warns.
  - CoolProp failure does not stop operation; density fallback is used.
  - non-operational states force predicted flow/power to zero.
- **BEP indicators**:
  - computes peak efficiency index and normalized CoG (`NCog`) for optimization usage by parent/group controllers.

## 9) Error Handling and Safeguards
- Invalid actions/sources are rejected by mode gates, with warnings (`nodes/rotatingMachine/src/specificClass.js:297`).
- Invalid setpoint (`<0` or non-number) is rejected in `setpoint()` (`nodes/rotatingMachine/src/specificClass.js:398`).
- Missing curve model disables predictor objects but keeps class alive (`nodes/rotatingMachine/src/specificClass.js:27`).
- Missing pressure initialization surfaces Node-RED warning ring status (`nodes/rotatingMachine/src/nodeClass.js:126`).
- `simulateMeasurement` rejects non-finite values and unsupported types (`nodes/rotatingMachine/src/nodeClass.js:312`).

## 10) Test Evidence Matrix
| Test file | Covered behavior |
|---|---|
| `nodes/rotatingMachine/test/basic/constructor.basic.test.js` | constructor curve/no-curve behavior and output shape |
| `nodes/rotatingMachine/test/basic/mode-and-input.basic.test.js` | `setMode`, `handleInput` validation, operational-state predicate |
| `nodes/rotatingMachine/test/edge/error-paths.edge.test.js` | negative setpoint resilience, status failure path |
| `nodes/rotatingMachine/test/edge/nodeClass-routing.edge.test.js` | input-topic routing, pressure initialization status warning, curve/CoG reply routing |
| `nodes/rotatingMachine/test/integration/sequences.integration.test.js` | startup sequence and movement execution |
| `nodes/rotatingMachine/test/integration/registration.integration.test.js` | child registration and pressure event propagation |
| `nodes/rotatingMachine/test/integration/pressure-initialization.integration.test.js` | explicit pressure init combinations and real-vs-virtual pressure priority |
| `nodes/rotatingMachine/test/integration/coolprop.integration.test.js` | efficiency path with CoolProp and medium-pressure initialization behavior |
| `nodes/rotatingMachine/test/integration/basic-flow-dashboard.integration.test.js` | example-flow parser/wiring contracts for dashboard topics |

## 11) Invariants (Anchor Truth)
- `specificClass` is the mechanical/logic source of truth; `nodeClass` is routing/lifecycle only.
- Prediction calculations must be curve-backed when curve exists, and availability-first fallback when it does not.
- Pressure selection priority is **real sensor > virtual dashboard > aggregated fallback**.
- Command execution must remain mode-gated by both action and source.
- Output shape must keep process/influx separation and parent registration on output port 2.
- Operational-state gating must continue to prevent active prediction outputs in inactive states.

## 12) Known Gaps / Risks (Current Implementation)
- `nodeClass` routes topic `CoG` to `m.showCoG()`, but `showCoG` is not present in `specificClass` (runtime risk on that topic): `nodes/rotatingMachine/src/nodeClass.js:340`.
- `handleInput('emergencystop')` calls sequence `"emergencyStop"`, but config default key is `"emergencystop"` (case/name mismatch risk): `nodes/rotatingMachine/src/specificClass.js:327`, `nodes/generalFunctions/src/configs/rotatingMachine.json:381`.
- `_setupSpecificClass` uses `machineConfig.eneableLog` (typo) for state logging config; likely not intended: `nodes/rotatingMachine/src/nodeClass.js:86`.
- Label expression can evaluate unexpectedly because `+` and `||` precedence are mixed: `nodes/rotatingMachine/rotatingMachine.html:58`.
