The public disk was accidentally removed during the Laravel 11 upgrade
and re-added as local_public in the FileDisk refactor. Restoring the
standard Laravel name avoids breaking Spatie MediaLibrary expectations
and simplifies the v2-to-v3 upgrade path.
User avatars and company logos now explicitly use the public disk via
registerMediaCollections(), keeping them web-accessible while the default
media disk remains private for sensitive documents like PDFs and receipts.
The v3 upgrade migration renames the system disk entry and any alpha media
records from local_public back to public.
Major changes to the file disk subsystem:
- Each FileDisk now gets a unique Laravel disk name (disk_{id}) instead
of temp_{driver}, fixing the bug where multiple local disks with
different roots overwrote each other's config.
- Move disk registration logic from FileDisk model to FileDiskService
(registerDisk, getDiskName). Model keeps only getDecodedCredentials
and a deprecated setConfig() wrapper.
- Add Disk Assignments admin UI (File Disk tab) with three purpose
dropdowns: Media Storage, PDF Storage, Backup Storage. Stored as
settings (media_disk_id, pdf_disk_id, backup_disk_id).
- Backup tab now uses the assigned backup disk instead of a per-backup
dropdown. BackupsController refactored to use BackupService which
centralizes disk resolution. Removed stale 4-second cache.
- Add local_public disk to config/filesystems.php so system disks
are properly defined.
- Local disk roots stored relative to storage/app/ with hint text
in the admin modal explaining the convention.
- Fix BaseModal watchEffect -> watch to prevent infinite request
loops on the File Disk page.
- Fix string/number comparison for disk purpose IDs from settings.
- Add safeguards: prevent deleting disks with files, warn on
purpose change, prevent deleting system disks.
