WIP: Sicherheitsnetz vor Phase-1-R\u00fcckbau
Enth\u00e4lt gemischt: Laravel-10-Upgrade + Phase 1 (Contacts-Modul, Duplicats-Commands, Soft-Delete+Merge-Fields) + Phase 2 Code-Umstellungen (inquiry_id, $table='contacts'/'inquiries') + Offers-Modul (Migrationen, Models, offer_id in Booking, offer-Disk in filesystems.php). Phase 2 + Offers werden im folgenden Commit nach dev/backups/phase2-offers-2026-04-17/ verschoben, damit der Workspace auf Phase-1-only (= Test-System-Stand) reduziert ist und direkt auf Live deploybar wird. Tarball-Backup zus\u00e4tzlich unter: ../backups-safety/workspace-pre-phase1-rollback-2026-04-17.tar.gz Made-with: Cursor

/**
|

* Phase 1 — Schritt 2: Duplikate zusammenführen
|
||||
*
|
||||
* Strategie: Der neueste Datensatz (höchstes updated_at, dann höchste id)
|
||||
* wird Master. Alle anderen Datensätze derselben Gruppe erhalten
|
||||
* merged_into_id = master_id und werden nicht mehr zurückgegeben.
|
||||
*
|
||||
* Alle FK-Referenzen in lead, booking, customer_mails, lead_mails
|
||||
* werden auf den Master umgestellt.
|
||||
*
|
||||
* Verwendung:
|
||||
* php artisan contacts:merge-duplicates --dry-run # Vorschau, keine Änderung
|
||||
* php artisan contacts:merge-duplicates --confidence=HIGH # Nur sichere Duplikate
|
||||
* php artisan contacts:merge-duplicates # Ausführen
