Summary

• Skip null pipe rows in search_pipes for named and unfiltered searches.
• Preserve valid results, fuzzy ranking, caps, and pipesCount. Mark results incomplete when the API includes a null row.
• Treat a null pipe list as empty and keep upstream errors visible. Add no retry or API request.
• Explain null rows in the SDK, MCP description, and organization reference. A truncation flag alone does not prove a cap cut.

Test plan

• uv run pytest -m "not integration" (CI: 5,686 passed, 6 skipped, 46 deselected).
• uv run ruff check . && uv run ruff format --check . (CI).
• Focused SDK and facade tests: 60 passed, including 10 regression cases.
• Ruff and formatting passed for the three changed Python files.
• Manual smoke (if applicable).

Focused command: python -m pytest -q -p no:cacheprovider packages/sdk/tests/services/test_pipe_service.py packages/sdk/tests/services/test_pipefy_client.py::test_search_pipes_delegates_to_pipe_service --tb=short.
