Changelog

All notable changes to this project will be documented in this file. The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

Added

  • Flow-Sync ist jetzt ein manueller Full-Pass: POST /api/flows/sync (Button "Aus Langflow synchronisieren" in der Verwaltung) holt erst alle Flows aus Langflow nach backend/flows/*.json und deployed sie danach automatisch (Report mit pulled-Liste). Der Hintergrund-Beobachter und der Startup-Sync bleiben dateibasiert. Die Verwaltung zeigt eine deutsche Schritt-Anleitung direkt beim Sync-Button.
  • LLM-Provider-Umgebung für Langflow: OPENAI_API_KEY + OPENAI_BASE_URL in .env (OpenAI-kompatible Endpoints) erzeugen automatisch restart-feste Global Variables in Langflow; LFX liest dieselben Werte.
  • Langflow-Sitzungen halten länger: LANGFLOW_REFRESH_TOKEN_EXPIRE_SECONDS (Default weiter 7 Tage, Dev-Beispiel 90) + stabile JWT-Signatur via LANGFLOW_SECRET_KEY — kein Re-Login nach Container-Restarts.

Fixed

  • Flow-Sync aus Langflow: neue Flows blieben unsichtbar, weil LFX-Uploads mit Permission denied scheiterten (named Volume root-owned, LFX läuft rootless). lfx-entrypoint.sh chownt /flows per gosu vor dem Start; zusätzlich Pull-Dedup (wiederverwendet gleichnamige/identische Dateien statt Bindestrich-Duplikate wie simple-rule.json, die jede Sync-Meldung mit Namenskonflikten füllten).
  • Sync-Dateinamen behalten die Langflow-Namen (test_flow.json statt test-flow.json; nur dateisystem-reservierte Zeichen werden ersetzt).
  • Gezogene Flow-Dateien sind world-readable (0o644): mkstemp erzeugte 0o600-Dateien, die Langflow beim Start abstürzen ließen (Permission denied in /app/flows, Crash-Loop) und der API Fehler (unreadable) verursachten.
  • LANGFLOW_SECRET_KEY muss ein gültiger Fernet-Key sein (44 Zeichen, urlsafe-base64): ein Hex-String brach die Variablen-Verschlüsselung mit Fernet key must be 32 url-safe base64-encoded bytes (500 beim Anlegen von Global Variables — Provider-Keys ließen sich nicht speichern). .env.example dokumentiert die Erzeugung.
  • LFX runtime user gets a home directory (useradd -m, HOME set): without one every flow run failed with "Settings service not found".

Security

  • Production ops: scripts/check_prod.py validates .env secrets and modes before deploy (with tests); README production checklist (proxy gates for Langflow, secret rotation, upgrade runbook).

Security

  • API authorization: flow management is admin-only, runs and run/approval reads require login with strict session-tenant scoping, approval decisions record the session user, and flow callbacks authenticate with a shared X-Callback-Token (CALLBACK_TOKEN). Request-controlled tenant_id, callback_base_url and continuation_flow_id were removed (SSRF / cross-tenant / flow-chaining hardening); continuations now resolve from the admin-authored definition.
  • Frontend: /app/* routes require login; approver is the session user.
  • Edge hardening: interactive API docs only with debug, security headers (nosniff/frame/Referrer-Policy), 2 MiB body cap, per-IP run throttle, generic upstream-error responses, magic links never logged.
  • Containers run rootless (api/vite as uid 1000, lfx as lfx user); frontend fails closed to preview mode unless FRONTEND_MODE=dev.

Added

  • Landing page: status-quo problem block, 5-step process with quote, portal overview with admin areas, AI platform parts, exception tiers, quantified benefits, integrations, use-case examples, pilot-program section, expanded FAQ (8 items incl. KI data usage, price model, responsibility).

Changed

  • Landing page copy overhauled after 3 reviewer rounds (church-admin compliance wording: "entwickelt nach DSG-EKD/DSGVO" + AVV/TOMs, human release responsibility, honest pilot framing instead of invented testimonials; CTA now "Pilotgespräch vereinbaren").
  • New photo pilot-meeting.webp (consultation scene, self-hosted).
  • Backend lint + format standards via ruff (pinned dev dependency, enforced in CI): uv run ruff check ., uv run ruff format.

[0.1.0] - 2026-09-13

Added

  • Repo scaffold: docker-compose dev/prod, version-pinned images, devcontainer.
  • Magic-link auth, access requests, RBAC, frontend access-management UI.
  • File-based flow source of truth + sync engine + LFX runtime.
  • RJSF dynamic forms, router, Mantine dark-mode design system.
  • Conversion landing page, automated screenshots, bell-tower favicon.
  • Email-first login, branded multipart HTML magic-link mails.
  • lfx level-4 validation on all canonical flows + regression test.
