Background

Scheduling a project for deletion would automatically put them into an archived state. Similarly, restoring them would put them back into an active state.

Proposal

Remove this behavior to keep archived as a separately managed state.

This is in line with the our state transitions where restoring a group/project would put it to its previous archived state.

This also helps simplify the work needed for &19690 (comment 2837069265)
