Module backup 

Backup session management for undo safety net.

Before any --apply write, commands save the original content of each affected file to .patchloom/backups/<timestamp>/. The patchloom undo command restores the most recent (or a chosen) backup.

Structs

BackupSession

An active backup session that collects originals before writes.

Manifest

The manifest for a backup session.

ManifestEntry

A single file entry in the backup manifest.

Enums

FileAction

What the apply operation did to a file.

Constants

BACKUP_DIR

Directory name under the project root.

Functions

backup_write_files

list_sessions

List available backup sessions, most recent first.

prune_old_backups

Remove a consumed backup session directory so subsequent undo calls reach older sessions instead of replaying the same one.
