Four archives, four explicit readiness states.

01Before installation

Resolve uncertain archives before they move.

Mixed roots and ambiguous content open in a focused inspector. Tailmark shows the archive tree, explains the warning, and asks for the missing destination or type.

The inspector keeps the archive and the decision in one view.

02After installation

Keep installed content organised and recoverable.

User skins, sound packages, collections, sights, hangars, and backups remain visible after installation, with safe-mode controls close by.

Installed content and its recovery state stay together.

03Operation record

Every file change leaves a readable trail.

Activity records installs, activations, destinations, and results so a later rollback starts with evidence instead of guesswork.

The operation history is persistent and exportable.

  2. Recoverable changes

    Replaced content is backed up before Tailmark installs over it.

  3. No account

    The Windows app and its operation history stay on the computer.
