Lukas Geiger · claude · Lukas Geiger · commit b744401206b1 · 2026-06-05T11:49:21.000+02:00
- Ruff auto-fix: 58 unused imports entfernt (F401/F541 pre-existing style)
- src/__init__.py: Re-Exports auf X-as-X-Syntax umgestellt (Ruff F401)
- Capability-Probe-Imports mit # noqa: F401 markiert (ftfy, PIL.Image, pip_licenses)
- BUGS.md angelegt: 2 bekannte nicht-kritische Defekte dokumentiert
  (B-001: Modell-Auswahl silent broken; B-002: roter Border bleibt)
- llms.txt committed (Projekt-Metadaten fuer LLM-Agents)

+# Bekannte Defekte (BUGS.md)
+
+Defekte, die beim Bug-Sweep identifiziert, aber nicht im laufenden Sweep behoben wurden.
+Format: `[Status] Titel — Kurzbeschreibung`
+
+---
+
+## Offen
+
+### B-001: Modell-Auswahl nicht funktional
+**Status:** Offen  
+**Datei:** `src/gui/main_window.py` — `_apply_settings()`  
+**Schwere:** Mittel (Feature silent broken)  
+**Beschreibung:**  
+`_apply_settings()` liest `ai.model` aus den Einstellungen, ruft aber `ai_service.set_model()` nie auf. Der gespeicherte Wert ist zudem der Anzeigename (z. B. "Claude Haiku") statt der API-ID. Die Modell-Auswahl in den Einstellungen wird daher vollständig ignoriert.  
+**Workaround:** Keiner. Das KI-Modell bleibt beim Standardwert der `AIService`-Instanz.
+
+### B-002: Rotes Validierungs-Rahmen in NewProjectDialog wird nicht zurückgesetzt
+**Status:** Offen  
+**Datei:** `src/gui/dialogs/new_project_dialog.py` — `_validate_input()` / `name_edit`  
+**Schwere:** Gering (kosmetischer UX-Defekt)  
+**Beschreibung:**  
+Wenn der Benutzer im `NewProjectDialog` einen ungültigen Projektnamen eingibt und auf "Erstellen" klickt, setzt `_validate_input()` einen roten Rahmen auf `name_edit`. Sobald der Benutzer dann wieder zu tippen beginnt, wird dieser Rahmen nicht automatisch zurückgesetzt. Der rote Rahmen bleibt, bis das Formular neu validiert wird.  
+**Workaround:** Nutzer muss das Formular erneut absenden, um den Rahmen zu entfernen.

+# DevCenter
+
+Canonical repository: https://github.com/dev-bricks/DevCenter
+
+DevCenter is a local-first Python desktop IDE and developer toolkit from dev-bricks. It combines a PySide6 editor, static analysis, encoding repair, PyInstaller build helpers, icon conversion, third-party license collection, project/file indexing, backup-oriented sync helpers and an optional Claude/Anthropic AI assistant.
+
+Primary audience:
+- Python developers who want a lightweight Windows-first desktop IDE.
+- Maintainers who need local analysis, build and release helpers in one app.
+- LLM agents that need project metadata and redacted status exports without uploading full source trees.
+
+Positioning:
+- This is not Azure DevCenter, Microsoft Dev Box, Moderne DevCenter or Devbox.
+- This is not a hosted cloud IDE.
+- The desktop app is authoritative; the Web/PWA companion is planned as a read-only viewer for redacted `devcenter-workspace-v1.json` exports.
+
+Privacy and safety:
+- Projects, settings, file indexes and build artifacts stay local by default.
+- Network access is only expected for explicitly configured integrations such as the optional Claude/Anthropic API or package installation commands started by the user.
+- API keys, tokens, local absolute paths and full source contents must not be written into public exports.
+
+Important files:
+- `README.md`: user-facing overview, screenshots, installation and feature list.
+- `PRIVACY_POLICY.md`: privacy scope for local settings, indexes, build artifacts and optional API use.
+- `EXPORTFORMAT.md`: planned redacted workspace export contract.
+- `PORTIERUNGSPLAN.md`: desktop, Web/PWA, Linux, macOS and Store strategy.
+- `.github/workflows/tests.yml`: Windows smoke tests for Python 3.10, 3.11 and 3.12.
+
+Useful search phrases:
+- local-first Python IDE
+- PySide6 Python development suite
+- Windows Python IDE with PyInstaller build helper
+- offline Python code editor and static analyzer
+- Python developer toolkit with license collector
