+# dashboardAPI — Contract
+
+dashboardAPI is an EVOLV utility node that listens for child-registration
+events from other EVOLV nodes and emits Grafana dashboard upsert HTTP
+requests on Port 0. It has **no domain measurements, no tick loop, and no
+parent of its own** — it is a one-shot HTTP emitter. Per
+OPEN_QUESTIONS.md (2026-05-10) it does NOT extend `BaseNodeAdapter` /
+`BaseDomain`; it uses the shared command registry only.
+
+## Inputs (msg.topic on Port 0)
+
+| Canonical | Aliases (deprecated) | Payload | Effect |
+|---|---|---|---|
+| `child.register` | `registerChild` | string (child node id) **or** `{ source: {...} }` **or** `{ config: {...} }` (optionally `msg.includeChildren: boolean`, default `true`) | Resolves the child source (`RED.nodes.getNode` → `node._flow.getNode` → inline payload), calls `source.generateDashboardsForGraph(child, { includeChildren })`, then emits one `topic: 'create'` HTTP-upsert message on Port 0 per generated dashboard. |
+
+Aliases log a one-time deprecation warning the first time they fire.
+
+## Outputs (msg.topic on Port 0/1/2)
+
+- **Port 0 (process):** one message per generated dashboard, shaped for a
+  downstream `http request` node:
+  ```js
+  {
+    topic: 'create',
+    url: <grafanaUpsertUrl>,           // e.g. http://grafana:3000/api/dashboards/db
+    method: 'POST',
+    headers: {
+      Accept: 'application/json',
+      'Content-Type': 'application/json',
+      Authorization: 'Bearer …'        // only when bearerToken is set
+    },
+    payload: { dashboard: {…}, folderId: 0, overwrite: true },
+    meta: { nodeId, softwareType, uid, title }
+  }
+  ```
+  Re-emits the inbound `msg` fields by spread (`{...msg, ...}`) so any
+  caller-supplied correlation/trace fields propagate.
+- **Port 1 (InfluxDB telemetry):** **not used.** dashboardAPI has no
+  measurements; nothing is emitted on Port 1.
+- **Port 2 (registration / control plumbing):** **not used.** dashboardAPI
+  is a sink for `child.register`, not a source — it does not register
+  itself with any parent.
+
+## Events emitted by `source.emitter`
+
+None. The specificClass (`DashboardApi`) exposes no `EventEmitter` — it
+is a passive service that responds to method calls and returns built
+dashboard payloads.
+
+## Children accepted
+
+Any EVOLV node whose `nodeSource.config` includes
+`functionality.softwareType`. The graph walk reads children via
+`nodeSource.childRegistrationUtils.registeredChildren.values()`. A
+dashboard template is loaded from `config/<softwareType>.json` (with
+case-insensitive fallback and a `machineGroupControl → machineGroup.json`
+alias); a missing template is logged at `warn` and the dashboard is
+skipped.
+
+The dashboard's templating variables `measurement` and `bucket` are
+filled from the child's id and `positionVsParent` (or
+`config.defaultBucket` / `config.bucketMap[position]` overrides). The
+root dashboard is augmented with `links[]` entries pointing at each
+direct child dashboard.
+
+## Why no BaseNodeAdapter / BaseDomain
+
+- No `generalFunctions/src/configs/dashboardapi.json` — `BaseDomain`'s
+  constructor unconditionally calls `configManager.getConfig(ctor.name)`
+  and would throw. The local `dependencies/dashboardapi/dashboardapiConfig.json`
+  is for the editor menu endpoint, not the runtime config pipeline.
+- No periodic output — `BaseNodeAdapter`'s `_emitOutputs()` /
+  `outputUtils.formatMsg` pipeline assumes a delta-compressed Port 0/1
+  stream; dashboardAPI emits HTTP-shaped messages instead.
+- No registration to a parent — `BaseNodeAdapter._scheduleRegistration`
+  would emit a spurious `child.register` of its own.
+- No status badge / tick / measurements / children of its own.
+
+dashboardAPI uses the shared `commandRegistry` (canonical topic naming +
+alias-with-deprecation) and stops there.

+
+## 1. What this node is
+
+**dashboardAPI** is an HTTP-emitter utility node — it listens for `child.register` events from other EVOLV nodes and emits one Grafana dashboard upsert HTTP request per node on Port 0. It is not a domain in the `BaseDomain` sense: no measurements, no tick loop, no children of its own, no parent registration.
+
+## 2. Position in the platform
+
+```mermaid

+    classDef equip fill:#86bbdd,color:#000
+    classDef ctrl fill:#a9daee,color:#000
+    classDef neutral fill:#dddddd,color:#000
+```
+
+dashboardAPI has **no S88 level** — it's a utility node. Dashed arrows = inbound `child.register` events; the solid arrow is the outbound HTTP upsert on Port 0 to a downstream `http request` node.
+
+## 3. Capability matrix
+
+| Capability | Status | Notes |
+|---|---|---|
+| Accept `child.register` from any EVOLV node | ✅ | Resolves via `RED.nodes.getNode` → `node._flow.getNode` → inline payload. |
+| Emit Grafana dashboard upsert (Port 0) | ✅ | One msg per generated dashboard, shaped for `http request`. |
+| Walk child graph + emit per-child dashboards | ✅ | `includeChildren: true` by default; opt-out per call. |
+| Add root → child dashboard `links[]` | ✅ | Each direct child appears as a link on the root dashboard. |
+| Template selection by `softwareType` | ✅ | Reads from `config/<softwareType>.json`; case-insensitive fallback. |
+| Bearer-token auth | ✅ | Set via editor or `INFLUXDB_BUCKET` env (bucket only). |
+| Domain output on Port 0 | ❌ | Never. Port 0 carries HTTP request envelopes, not measurements. |
+| Port 1 telemetry / Port 2 registration | ❌ | Both unused — see Section 8. |
+| Status badge / tick loop / FSM | ❌ | Stateless; no periodic emission. |
+
+## 4. Code map
+
+```mermaid
+flowchart TB
+    subgraph nodeRED["nodeClass.js — passive adapter"]
+        nc["createRegistry(commands)<br/>dispatch on msg input<br/>NO BaseNodeAdapter"]
+    end

+    subgraph cmd["src/commands/"]

+    end
+    subgraph tpl["config/ (templates)"]
+        t["<softwareType>.json<br/>Grafana JSON skeletons"]

+```
+
+| Module | Owns | Read first if you're changing… |
+|---|---|---|
+| `src/nodeClass.js` | Input wiring, command dispatch, config build | Topic dispatching, configuration mapping. |
+| `src/specificClass.js` | Template loading, dashboard composition, child graph walk | UID stability, links, templating-var substitution. |
+| `src/commands/` | `child.register` handler + legacy alias | Adding / renaming inbound topics. |

+
+dashboardAPI deliberately does NOT split into `concerns/` — its surface is too narrow. See CONTRACT.md → "Why no BaseNodeAdapter / BaseDomain" for the rationale.
+
+## 5. Topic contract
+
+> **Auto-generated** from `src/commands/index.js`. Do NOT hand-edit between the markers. Re-run `npm run wiki:contract`.
+
+<!-- BEGIN AUTOGEN: topic-contract -->
+
+| Canonical topic | Aliases | Payload | Effect |
+|---|---|---|---|
+| `child.register` | `registerChild` | `any` | Parent/child plumbing — registers or unregisters a child node. |
+
+<!-- END AUTOGEN: topic-contract -->
+
+The legacy `registerChild` alias logs a one-time deprecation warning on first use. The payload can be a string (child id), `{ source: {...} }`, or `{ config: {...} }`; `msg.includeChildren` (default `true`) controls graph-walk depth.
+
+## 6. Child registration
+
+dashboardAPI does **not** maintain a child registry of its own. Instead, every inbound `child.register` triggers a one-shot resolution + dashboard emission. No state is held between calls.
+
+```mermaid
+flowchart LR
+    src["any EVOLV node<br/>(has functionality.softwareType)"]:::other -->|child.register| dash[dashboardAPI<br/>Utility]:::neutral
+    dash --> resolve[resolve child source<br/>RED.nodes.getNode → _flow → inline]
+    resolve --> walk["source.generateDashboardsForGraph(child)<br/>(includes children if flag set)"]
+    walk --> emit[emit one msg per dashboard<br/>topic='create']
+    emit --> http[(downstream<br/>http request node)]
+    classDef neutral fill:#dddddd,color:#000
+    classDef other fill:#ffffff,stroke:#666
+```
+
+| Inbound softwareType | Filter | Side effect |
+|---|---|---|
+| any | child has `functionality.softwareType` | Loads `config/<softwareType>.json`; emits one upsert msg per dashboard in the graph walk. |
+| (template missing) | no matching `config/*.json` | Warns and skips that dashboard. No error. |
+
+## 7. Lifecycle — what one event does
+
+```mermaid
+sequenceDiagram
+    participant emitter as any EVOLV node
+    participant dash as dashboardAPI
+    participant api as DashboardApi
+    participant out as Port-0 output
+    participant grafana as Grafana HTTP API
+
+    emitter->>dash: child.register {source / config / id}
+    dash->>dash: commandRegistry dispatch
+    dash->>api: generateDashboardsForGraph(child, {includeChildren})
+    api->>api: loadTemplate(softwareType)
+    api->>api: stableUid + updateTemplatingVar
+    api->>api: walk children via childRegistrationUtils
+    api-->>dash: [{dashboard, uid, title}, ...]
+    loop per dashboard
+        dash->>out: msg{topic:'create', url, method, headers, payload}
+        out->>grafana: POST /api/dashboards/db
+    end
+```
+
+One inbound event yields N outbound HTTP messages (N = 1 + direct child count when `includeChildren=true`).
+
+## 8. Data model — `getOutput()`
+
+> **dashboardAPI has no domain output.** It does not extend `BaseDomain` and does not implement `getOutput()`. The `wiki:datamodel` script falls back to the placeholder below.
+
+<!-- BEGIN AUTOGEN: data-model -->
+
+No domain output. dashboardAPI emits **HTTP request envelopes on Port 0**, shaped for a downstream `http request` node:
+
+```js
+{
+  topic: 'create',
+  url: 'http://<grafana>:<port>/api/dashboards/db',
+  method: 'POST',
+  headers: {
+    Accept: 'application/json',
+    'Content-Type': 'application/json',
+    Authorization: 'Bearer …'   // only when bearerToken is set
+  },
+  payload: { dashboard: {…}, folderId: 0, overwrite: true },
+  meta: { nodeId, softwareType, uid, title }
+}
+```
+
+Port 1 (InfluxDB telemetry) and Port 2 (registration / control plumbing) are unused — dashboardAPI has no measurements and does not register with a parent.
+
+<!-- END AUTOGEN: data-model -->
+
+See CONTRACT.md for the full envelope spec.
+
+## 9. Configuration — editor form ↔ config keys
+
+```mermaid
+flowchart TB

+|---|---|---|---|
+| Basic | `examples/01-Basic.flow.json` | Inject `child.register` payload + a downstream `http request` → mock Grafana | ⏳ TBD |
+| Integration | `examples/02-Integration.flow.json` | Real EVOLV node (e.g. pumpingStation) wired into dashboardAPI | ⏳ TBD |
+| Dashboard | _n/a_ | dashboardAPI **is** the dashboard plumbing — no FlowFuse tier | — |
+
+## 12. Debug recipes
+
+| Symptom | First thing to check | Where to look |
+|---|---|---|
+| No HTTP request emitted | Did the `child.register` resolve a source? `source.generateDashboardsForGraph` returns `[]` when child has no `config`. | `node_redlog` for "generateDashboardsForGraph skipped" warning. |
+| `Skipping dashboard generation: no template` | `config/<softwareType>.json` missing for this node type. | `config/` directory; add a template. |
+| Empty `Authorization` header | `bearerToken` not set in editor. | Editor form → Bearer token field. |
+| Wrong bucket in Grafana | `defaultBucket` overrides position-based default. Check `INFLUXDB_BUCKET` env. | `_buildConfig` in nodeClass.js. |
+| `registerChild` alias warns once | Expected — migrate callers to `child.register`. | Caller's `msg.topic`. |
+
+> Never ship `enableLog: 'debug'` in a demo — fills the container log within seconds and obscures real errors.
+
+## 13. When you would NOT use this node
+
+- Use dashboardAPI when you want **auto-generated Grafana dashboards** from EVOLV node topology. If you maintain dashboards by hand in Grafana, skip it.
+- Don't use dashboardAPI as a generic HTTP client — it only emits Grafana dashboard upserts. For arbitrary HTTP, use a plain `http request` node.
+- Don't put dashboardAPI in a hot data path. It fires on registration events, not on each tick — wiring tick data to it is a misuse.

+## 14. Known limitations / current issues
+
+| # | Issue | Tracked in |
+|---|---|---|
+| 1 | No domain output — cannot be introspected through the standard `getOutput()` channel; debugging relies on Port 0 HTTP envelopes. | CONTRACT.md → "Why no BaseNodeAdapter / BaseDomain" |
+| 2 | Template discovery is filename-based; renaming a node's `softwareType` requires renaming the template file (with the `machineGroupControl → machineGroup.json` alias being a one-off). | `_templateFileForSoftwareType` in specificClass.js |
+| 3 | No retry / circuit-breaker on the downstream `http request` — Grafana outages drop dashboards silently. | TBD |
+| 4 | Tier 1/2 example flows not yet written. | P9 wiki cleanup follow-up |

+No domain output. dashboardAPI emits **HTTP request envelopes on Port 0**, shaped for a downstream `http request` node:
+
+```js
+{
+  topic: 'create',
+  url: 'http://<grafana>:<port>/api/dashboards/db',
+  method: 'POST',
+  headers: {
+    Accept: 'application/json',
+    'Content-Type': 'application/json',
+    Authorization: 'Bearer …'   // only when bearerToken is set
+  },
+  payload: { dashboard: {…}, folderId: 0, overwrite: true },
+  meta: { nodeId, softwareType, uid, title }
+}
+```
+
+Port 1 (InfluxDB telemetry) and Port 2 (registration / control plumbing) are unused — dashboardAPI has no measurements and does not register with a parent.
