#!/usr/bin/env python3 # -*- coding: utf-8 -*- """ Script: scripts/import_markdown.py — Markdown → Qdrant (Notes, Chunks, Edges) Version: 3.5.0 Datum: 2025-09-09 Kurzbeschreibung ---------------- - Liest Markdown-Dateien ein, erzeugt Notes/Chunks/Edges **idempotent**. - **Änderungserkennung** (nur Inhalte, keine FS-Zeitstempel) konfigurierbar: * ``--hash-mode``: body | frontmatter | body+frontmatter | full (Alias) - Env: ``MINDNET_HASH_MODE`` **oder** ``MINDNET_HASH_COMPARE`` (Body/Frontmatter/Full) * ``--hash-normalize``: canonical | none (Default: canonical) * ``--hash-source``: parsed (Default) | raw - "raw" hasht den **ungeparsten** Body (Frontmatter via Regex entfernt). * **NEU**: ``--compare-text`` (oder ENV ``MINDNET_COMPARE_TEXT=true``) - Zusätzlich zum Hash wird der *parsed* ``fulltext`` direkt verglichen. - Erkennt Änderungen auch dann, wenn eine Normalisierung Unterschiede glättet. * **NEU**: Signaturabgleich: - Falls sich die Signatur (z. B. body→full, parsed→raw, canonical→none) zwischen Alt/Neu unterscheidet, gilt die Note als **geändert** (Einmal-Update, um neue Signatur zu persistieren).
