Project rename across api/ + web/: modules, symbols, routes (/console/api/dify-builder/*), feature flag (DIFY_BUILDER_ENABLED), Celery queue/tasks, the 7 DB tables (via migration df1b0114de40), and regenerated contract artifacts. Behavior unchanged; 430 tests green, ruff clean. Branch renamed feat/copilot-py-backend → dify-builder. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

"""Pure mapping from a Dify workflow-run result into the dify_builder domain.
|
|
|
|
``AppGenerateService.generate(..., streaming=False)`` returns a blocking
|
|
response dict; its ``["data"]`` sub-mapping plus the run's per-node
|
|
execution rows are all these functions need to build a dify_builder ``Run`` /
|
|
``NodeEvent``. No DB, no services, no I/O — node-execution rows are
|
|
duck-typed (``node_id``, ``node_type``, ``title``, ``status``, ``error``,
|
|
``.outputs_dict``/``.inputs_dict``) rather than importing the real
|
|
``WorkflowNodeExecutionModel``, so tests can pass lightweight stand-ins
|
|
(e.g. ``SimpleNamespace``).
|
|
|
|
Status mapping is intentionally conservative: only a clean ``SUCCEEDED``
|
|
finish counts as a dify_builder-domain "succeeded" run. ``FAILED``,
|
|
``PARTIAL_SUCCEEDED``, ``STOPPED``, and ``PAUSED`` all map to "failed", as
|
|
does the distinct *paused-shape* response (human-input node — carries
|
|
``paused_nodes``/``reasons`` instead of a clean ``status``/``outputs``/
|
|
``error`` shape). A verify run that didn't cleanly succeed should never
|
|
read as green to the user, even if it's technically "still running"
|
|
(paused) or "mostly fine" (partial success) rather than an outright error.
