|
|
**Null convention for this node:** a Port-0 key whose source is not yet
|
|||
|
|
available is emitted as **explicit `null`** (e.g. `timeleft`, `flowSource`,
|
|||
|
|
`manualDemand` outside manual mode), never silently absent. Delta-compression on
|
|||
|
|
Port 0 then drops keys whose value is unchanged since the previous tick.
|
|||
|
|
|
|||
|
|
## Port 0 (process data) — `specificClass.getOutput()` → `outputUtils.formatMsg(..., 'process')`
|
|||
|
|
|
|||
|
|
`msg.topic = config.general.name`. Keys below are the full pre-delta-compression set.
|
|||
|
|
|
|||
|
|
| Key | Source | Type | States tested | Test file |
|
|||
|

|

|
|||
|
|
| `direction` | `getOutput` ← `state.direction` | string (`filling`/`draining`/`steady`) | present | test/basic/specificClass.test.js |
|
|||
|
|
| `flowSource` | `getOutput` ← `state.flowSource` | string, `null` when no source | null (pre-child) | test/basic/specificClass.test.js |
|
|||
|
|
| `timeleft` | `getOutput` ← `state.seconds` | number s, `null` when steady | present, null | test/basic/specificClass.test.js |
|
|||
|
|
| `percControl` | `getOutput` ← `controlState.percControl` | number % 0..100 | 0, 25, 50, 75, 85, 100 | test/basic/specificClass.test.js |
|
|||
|
|
| `dryRunLevel` | `_computeSafetyPoints` | number m | populated | test/basic/specificClass.test.js |

|
|
## Port 1 (InfluxDB telemetry) — `formatMsg(..., 'influxdb')`
|
|||
|
|
|
|||
|
|
Same key set as Port 0 (formatted via the `influxdb` formatter rather than
|
|||
|
|
`process`). Field names == Port-0 keys; `config.general.name` is the measurement
|
|||
|
|
tag. No Port-1-only fields. Covered transitively by the Port-0 tests above; a
|
|||
|
|
dedicated Port-1 line-protocol assertion is a **gap** (see below).
|
|||
|
|
|
|||
|
|
## Port 2 (registration / control plumbing) — `BaseNodeAdapter._scheduleRegistration`
|
|||
|
|
|
|||
|
|
| Topic | Source | Payload shape | States tested | Test file |
|
|||
|
|
|---|---|---|---|---|
|
|||
|
|
| `child.register` | `BaseNodeAdapter.js:122` | `{ topic:'child.register', payload:<node.id>, positionVsParent, distance }` | — | _(gap — see below)_ |
|
|||
|
|
|
|||
|
|
> Note: the canonical outgoing topic is **`child.register`** (matching the input
|
|||
|
|
> registry). Earlier docs said `registerChild`; that is the deprecated input
|
|||
|
|
> alias, not what this node emits.
|
|||
|
|
|
|||
|
|
## Child-facing events — `measurements.emitter`
|
|||
|
|
|
|||
|
|
Fired as `<type>.<variant>.<position>` when a series receives a value. Parents
|
|||
|
|
subscribe by event name (data-driven, not a fixed catalogue):
|
|||
|
|
|
|||
|
|
| Event | When | Test file |
|
|||
|
|
|---|---|---|
|
|||
|
|
| `volume.predicted.atequipment` | each integrator tick | test/basic/flowAggregator.basic.test.js |
|
|||
|
|
| `level.predicted.atequipment` | recomputed from volume | test/basic/specificClass.test.js |
|
|||
|
|
| `flow.predicted.in` (child `manual-qin`) | `set.inflow` handler | test/basic/measurementRouter.basic.test.js |
|
|||
|
|
| `overflowVolume`/`underflowVolume`/`flow.predicted.overflow` | integrator hits a physical bound | test/basic/flowAggregator.basic.test.js |

Populated/structure coverage: test/integration/basic-dashboard-flow.test.js
|
|||
|
|
(asserts output count = 15 and routes outputs 0–14). **Degraded/empty-input**
|
|||
|
|
coverage (no `payload:null` reaching any `ui-chart`) is still a gap — see below.
|
|||
|
|
|
|||
|
|
## Known coverage gaps (tracked, prospective per the rule)
|
|||
|
|
|
|||
|
|
The output-coverage rule applies prospectively. Outstanding items for this node:
|
|||
|
|
|
|||
|
|
- [ ] Dedicated `test/basic/output-port0.test.js` exercising **every** key above
|
|||
|
|
in both populated and degraded (pre-tick / null) states.
|
|||
|
|
- [ ] Port-1 line-protocol assertion (field names + tag).
|
|||
|
|
- [ ] Port-2 `child.register` payload-shape test.
|
|||
|
|
- [ ] `fn_status_split` degraded/empty-input fan-out test (no `payload:null` to
|
|||
|
|
any `ui-chart`) — the failure mode the rule was written for. The structure
|
|||
|
|
test in `basic-dashboard-flow.test.js` covers the populated path only.
