src/services/backupService.ts moves to src/nest/backup/backup.impl.ts, imported only by its own domain now that the controller reaches it through BackupService. src/services/ is down to airtrail/. It stays a module of free functions rather than becoming methods on the service. The restore path closes and reinitializes the core DB handle, which is the single most dangerous sequence in the server, and rewriting its shape in the same step as the move would make a regression there impossible to bisect. The db-lifecycle question is the last step of this fold, not part of it. The move also pulled 512 lines out of ungated src/services/ into a gated domain, which is how the per-domain ratchet caught that the per-entry extraction loop had no tests at all: the zip-slip refusal, the running decompressed-byte cap (the declared size in the central directory is attacker-controlled, so only the running total catches a lying archive), a corrupt stream not being dressed up as a size refusal, and the reopen failure that has to report restart-required rather than success. Six cases now cover it, and backup goes from 84% to 96% statements.
