The pack builder accepts the aliases declared in the target overrides, so --target switch works there, but the installer's target manifests carried only canonical names. The documented word was the one that failed, and the installer then carried on with every file: 1911 files and 4.1 GB where the user had asked for the 863 that target needs. Aliases are emitted beside their canonical target, and an unknown target now stops the run and lists what is available. A filter is applied or refused, never ignored.
