Decisions — macros-and-labels-import

[2026-05-03] Architectural Decisions

Schema

• labels table: global, unique by name, nullable color, hidden_at (NOT deleted_at)
• macros table: unique by uuid (uppercase), hidden_at (NOT deleted_at)
• macro_assignments: restrictOnDelete on macro_id and label_id FKs
• service_macro_overrides: existence of row = override active; no extra boolean
• song_arrangement_labels: replaces song_arrangement_groups; references global label_id

Macro Assignment Semantics

• part_type enum: information | moderation | sermon | song | agenda_item
• position enum: all_slides | first_slide | last_slide | by_label
• by_label is valid for ALL part_types (not songs-only) — validated at app level if restriction needed
• Stacking: multiple assignments can fire on same slide — all applied in order ASC
• Override wins 100% — no globals bleed through when override exists

Override Semantics

• "Anpassen" snapshots current globals into service_macro_assignments rows
• "Auf Standard zurücksetzen" deletes the override row + cascades service_macro_assignments
• German tooltip: "Erstellt eine Kopie der aktuellen globalen Zuweisungen für diesen Gottesdienst. Spätere Änderungen an den globalen Zuweisungen wirken sich auf diesen Gottesdienst NICHT mehr aus."

Data Migration

• Destructive: up() deletes songs, song_groups, song_slides, song_arrangements, song_arrangement_groups
• down() throws RuntimeException (irreversible)
• Guard: if (!Schema::hasTable('song_groups') || !DB::table('song_groups')->exists()) return;
• Old 4 macro settings keys → migrated to global assignment if all present; then deleted

Label Color Priority

1. Labels file import → always sets/overwrites color
2. .pro song import → only sets color on CREATE (new label); existing color preserved
3. UI → read-only (no manual edit)

Current Migration Scope

• labels migration only defines the schema; no model or business logic belongs in this task
• Use hidden_at instead of deleted_at to align with soft-hide semantics
