Type: slice / docs

Depends on: #40

Estimate: M (1–2 days)

Slice — layers touched

example flow → docker provisioning cleanup → docs.

Context

Proof that the generator works for the canonical example. Anchors PRD §8.2 (≤15 ui-* nodes) and §8.3 (time-to-first-dashboard ≤1 min).

Scope

  • Strip the 73-node Dashboard tab in pumpingstation-complete-example flow down to control-only widgets (mode, demand, calibration, signal injection) — target ≤15 ui-* nodes.
  • Drop in one dashboardAPI, configure URL + token, deploy.
  • Remove docker/grafana/provisioning/dashboards/pumping-station.json (now dynamic).
  • Update the project's README/CLAUDE.md to point to the generator as the canon.

Out of scope

  • Migrating the other 9 example flows — those are follow-ups, not in this PRD.

Acceptance criteria

  • Active flow has ≤15 ui-* nodes (verified by counting ui-* types in flow.json).
  • docker/grafana/provisioning/dashboards/pumping-station.json deleted.
  • Grafana dashboard at the dashboardAPI's UID renders all expected panels for the migrated flow.
  • Stopwatch: a fresh R&D engineer can build a new example flow + see a Grafana dashboard in ≤1 minute.

Slice #42 partially shipped — example round-trip done; active flow migration deferred

Branches: dashboardAPI · EVOLV

What landed

  • nodes/dashboardAPI/examples/basic.flow.json: replaced the placeholder inject→dashboardapi→debug with a real round-trip: inject (simulating measurement child.register) → dashboardapi (composes dashboard JSON) → http request (POSTs to Grafana) → debug (shows response). Configured for the Docker compose stack (host: grafana, port: 3000, bucket: telemetry).

What's deferred and why

The PRD §8.2 success metric is "active flow ≤15 ui-* nodes (down from 73)." The active flow lives in the container's named-volume project (/data/projects/pumpingstation-complete-example/) and migrating it means visually walking 73 ui-chart/ui-gauge/ui-text/ui-button/ui-slider/fan-out function nodes:

  • Keep: ui-button (mode select, signal injection), ui-slider (operator demand, calibration setpoints), ui-switch (control mode toggles), ui-template (small control headers).
  • Delete: ui-chart, ui-gauge, ui-text reading telemetry, fan-out function nodes that split signals onto ui-charts.
  • Re-wire: the deleted telemetry consumers' upstream signal sources need to be confirmed unconnected before deletion (else they break upstream nodes).

That's a 30-60 minute visual session, not a script — risks breaking the working flow if done blindly. Recommended next step: schedule a focused review session where I drive the deletions interactively and you confirm each cluster of nodes before they go.

Also pending in that same session:

  • Drop docker/grafana/provisioning/dashboards/pumping-station.json (becomes dynamic).
  • Update README/CLAUDE.md to point at the generator.

Acceptance criteria (status)

  • Active flow ≤15 ui-* nodes — deferred to interactive session.
  • pumping-station.json removed — pending the same session.
  • Example flow demonstrates the round-trip — examples/basic.flow.json updated.
  • Stopwatch test (new flow + Grafana dashboard ≤1 min) — runnable once the active flow is migrated.

Leaving issue open since the headline success metric isn't met yet. The smaller example round-trip is in.
