## [Unreleased]
+### Changed
+- Declutter: shared `BaseApiClient` (LFX/Langflow), single `get_db`, `model_validate` mappers, unified LFX/Langflow error mapping, stream logic moved to `runner.py`, `sync_full_pass` single orchestration (API+CLI), shared model base (`utcnow`/`ts_column`), unified auth counters, `httpx` in `deploy_flow.py`.
+- Forms: shared `components/kirche/_form_core.py` single source (codegen-inlined for LFX), structured `visible_if` key alongside legacy markers, `LangflowClient.upsert_flow` + `scripts/push_flows_to_langflow.py` (6 canonical flows pushed to Langflow UI).
+- Tests (full real LFX kept, 146 green): shared `conftest` helpers (`load_flow_fixture`, `flow_helpers`, `lfx_client`, `anon_client`), `tests/_harness.py` shared with smoke script, parametrized `filename_stem`.
+- Frontend: shared `formatApiError`, ``, ``, `URLSearchParams` queries, localized run dates.
### Added
- Branched questionnaires: `[visible_if feld=Wert]` markers in a
`CustomInputForm` field's `info` (code editor) show the field only when
