-## Logging
-
-Beide Dienste schreiben strukturierte, einzeilige JSON-Log-Zeilen nach
-stdout/stderr (`docker compose logs --follow`). Jede Zeile enthält
-`timestamp`, `level`, `scope` und `message`. `compose.yaml` konfiguriert für
-beide Dienste den `json-file`-Treiber mit Rotation (`max-size: 20m`,
-`max-file: 10`, also bis zu 200 MB je Dienst); ohne diese Einstellung würde
-Docker mit der Standardkonfiguration unbegrenzt in eine einzelne Datei unter
-`/var/lib/docker/containers/<container-id>/` schreiben. Die Logs überleben
-einen Container-Neustart (`docker compose restart`), aber nicht das Entfernen
-des Containers (`docker compose down` gefolgt von `up` erzeugt neue
-Container und damit neue, leere Logdateien); für ein echtes Langzeitarchiv
-über Rebuilds hinweg müssten die Zeilen zusätzlich in eine Datei im
-gemounteten `./data`-Verzeichnis oder an ein externes Log-System geschrieben
-werden. Die Express-API protokolliert
-jede abgeschlossene Anfrage (Methode, Pfad, Status, Dauer; `/health` wird
-nicht mitgeloggt) sowie unbehandelte Exceptions/Promise-Rejections. Das
-Next.js-Frontend protokolliert Seitenanfragen (Navigation) über
-`src/proxy.ts` und unbehandelte Fehler über `src/instrumentation.ts`.
-Beide Prozesse schreiben zusätzlich alle fünf Minuten einen `verbose`-Heartbeat
-mit Laufzeit und Speicherverbrauch – nützlich, um Speicherlecks oder Hänger vor
-einem 502 über einen längeren Zeitraum nachzuvollziehen. Für die Detailsuche
-`LOG_LEVEL=debug` setzen; das protokolliert zusätzlich den Start jeder
-API-Anfrage und macht damit hängende (nie abgeschlossene) Requests sichtbar.
-Ein `close`-Ereignis ohne vorheriges `finish` wird als `request aborted before
-response finished` (`warn`) geloggt und zeigt damit vom Client oder einem
-vorgeschalteten Proxy abgebrochene Verbindungen.
-
-Eine unbehandelte Exception oder Promise-Rejection wird geloggt und beendet
-den jeweiligen Prozess anschließend bewusst (`process.exit(1)`), statt in
-einem unbekannten Zustand weiterzulaufen. Beide Dienste laufen deshalb mit
-`restart: unless-stopped`, damit Docker sie danach automatisch neu startet;
-ohne diese Policy würde ein Crash den Dienst dauerhaft unerreichbar lassen.

-# Revit 2026 / Dynamo diagnostics
-
-This directory contains self-contained Python scripts for a Dynamo **Python
-Script** node. They use only Dynamo's built-in Revit integration, the Revit API
-and the Python standard library. No Dynamo package is required.
-
-The scripts are read-only. They do not start a Revit transaction and do not
-change the open model.
-
-## Python engine
-
-Use the built-in `CPython3` engine in Revit 2026. Autodesk ships Dynamo with
-Revit; optional PythonNet3 packages are not required by these diagnostics.
-
-## 01 - Check model identity
-
-File: `01_check_model_identity.py`
-
-The script reports:
-
-- Revit, Dynamo and Python versions;
-- `ProjectInformation.UniqueId` as a native model-identity candidate;
-- all occurrences and values of `LB_ModelId` and `LB_ProjectId` on Project
-  Information;
-- all Project Information parameters;
-- optional cloud/worksharing identity information when the API exposes it.
-
-Input `IN[0]` is optional. It may be either an output directory or a complete
-`.json` file path. With no input, the report is written below the current
-Windows temporary directory in `leistungsbilanz-dynamo`.
-
-## 02 - Inventory Electrical Fixtures parameters
-
-File: `02_export_electrical_fixture_parameter_inventory.py`
-
-The script reads every instance of
-`BuiltInCategory.OST_ElectricalFixtures` in the complete current document. It
-exports:
-
-- element, family, type and MEP Space identities;
-- every instance parameter and value;
-- every unique family-type parameter and value;
-- an aggregated parameter inventory with occurrence counts and sample values;
-- per-element warnings instead of aborting at the first unreadable element.
-
-Inputs:
-
-- `IN[0]` (optional): output directory or complete `.json` path;
-- `IN[1]` (optional): include empty parameters, default `true`;
-- `IN[2]` (optional): maximum sample values per aggregated parameter, default
-  `5`.
-
-The default output location is again the Windows temporary directory. The
-generated report can contain model paths and project-specific parameter values;
-review it before sharing or committing it.
-
-## Running a script
-
-1. Open the target model in Revit 2026.
-2. Open Dynamo from **Manage > Visual Programming > Dynamo**.
-3. Create a graph and add a **Python Script** node.
-4. Select the `CPython3` engine for the node.
-5. Copy the complete content of the desired `.py` file into the node.
-6. Optionally connect a String node containing the output path to `IN[0]`.
-7. Run the graph and inspect `OUT` for status, counts and the generated path.
-
-For the first test, run `01_check_model_identity.py` in the Revit main model.
-Then run the parameter inventory. Keep both generated JSON files so their
-structure can be checked before the production snapshot DTO is finalized.
