Scope

Build a full-height Dataflow workspace with pipeline selection, a node palette, draggable canvas, connectable typed edges, node inspector, SQL editor, validation panel, and preview table. Graphical and SQL modes operate on the same canonical definition and make lossy conversion explicit.

Acceptance Criteria

  • Users can drag transforms onto the canvas, connect them, reposition them, select them, edit configuration, and delete them.
  • A visible connection preview/drop target makes edge creation clear.
  • SQL mode validates and compiles without losing the last saved graph on failure.
  • Save, discard, preview, loading, empty, error, conflict, and unsaved states are complete.
  • Keyboard access, focus handling, responsive sizing, and non-overlapping full-height layout are verified.
  • WebUI structure tests and a production TypeScript build pass.

Codex State: progress

Summary

  • Implemented the full-height Dataflow workspace with pipeline selection, drag/drop node palette, connectable React Flow canvas, node inspector, SQL workbench, validation, bounded preview, conflict handling, save/discard/delete, and result diagnostics.

Changed Files

  • webui/src/features/dataflow
  • webui/src/api/dataflow.ts
  • webui/src/styles/dataflow.css

Verification

  • WebUI structure test, standalone TypeScript typecheck, Dataflow-only production build, and full-product build pass.

Next / Blocked

  • Run browser-level interaction, keyboard/focus, and responsive visual checks before closing this package.

Suggested status label: status/in-progress

Codex State: progress

Summary

  • The full-height editor now consumes the backend catalogue and groups reusable nodes under Load, Combine, Filter, Transform, and Output.
  • Typed/multi-input ports, join-side handles, cycle/fan-in checks, connector source selection, JSON/CSV import, node-specific inspectors, and preview lineage summaries are implemented.
  • TypeScript, structure tests, Dataflow-only builds, and full-product builds pass.

Verification

  • python -m unittest discover -s govoplan-connectors/tests (7 passed)
  • python -m unittest discover -s govoplan-dataflow/tests (24 passed)
  • tools/checks/check-contracts.sh (45 contracts passed)
  • tools/checks/check-focused.sh (core, module, API, and WebUI checks passed)
  • Composed JSON/CSV snapshot and connector-backed preview probe passed.

Next / Blocked

  • Keep open for focused keyboard/focus testing and desktop/mobile interaction screenshots against a running app.
