…tamped op batch (BE-11131) --emit-workflow writes API format, which the canvas and every edit tool refuse (workflow_not_frontend_format) and which a shared-document consumer cannot attribute. --emit-ops re-expresses the SAME graph (build_workflow stays the single source of the model→node mapping) as add_node/set_widget/connect specs and materializes it through workflow_ops.apply_specs — the machinery every hand edit uses, so widget order, autogrow and positions have one answer. The file on disk becomes frontend format (canvas-editable), and the envelope carries the replace_ops batch exactly like templates fetch --emit-ops, so the consumer folds the replacement in as attributed ops. Also fixes a latent converter bug the round-trip contract exposed: convert_ui_to_api paired widgets positionally from the input DICT's order and ignored input_order, silently swapping neighboring widget values on any re-serialized catalog (GeminiImageNode's prompt/model traded places on an alphabetized fixture). It now honors input_order the way the cql engine's _ordered_names does. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QX1YteLA2BYbfjup13xNg1

Merge Risk: 🔵 Low · up to The new workflow-operation generation flags work through custom argument parsing, but invalid flag combinations may leave incomplete error telemetry and the new options do not receive normal CLI help and validation behavior.

- Line 614: Wrap the _get_graph call in generate with a typer.Exit handler that
invokes _track_error("emit", exc) before re-raising the same exception, ensuring
exits after cql_no_graph produce a terminal generate:error event while
preserving existing exit behavior.
- Around line 607-617: Update the invalid base-version handling in the generate
command to pass the caught conversion exception to _bail instead of directly
raising after renderer.error. Preserve the generate_bad_args user-facing message
while ensuring _track_error records the matching generate:error lifecycle event.

- Line 3: Remove the internal ticket identifier “BE-11131” from the comment text
in test_emit_ops.py and replace it with a concise, non-sensitive description of
the --emit-workflow behavior. Preserve the existing explanation about API-format
output and canvas compatibility.

… from the test docstring Public-repo hygiene rejected the ticket identifier in the test module docstring; it now states the reason in plain words. Two review follow-ups: an invalid --base-version goes through _bail so generate:error is recorded before the exit, and a typer.Exit raised by _get_graph (cql_no_graph) is tracked before it is re-raised, so generate:start is never left without its terminal event.
