Residual of BOX T126 (#3254, PR #3301), from arch condition C3 (arch_rulings 1173).
crates/minimal/src/dash/app.rs creates a box by calling prepare_activation_inputs_with_config with opts.loadouts. It never calls entry_loadout_gate. So a min dash create of a sealed entry still reads and applies loadouts, against BOX-166 and BOX-175, and a loadout named for a sealed box is not refused as BOX-173 requires.
Scope: have the min dash create path call entry_loadout_gate and gate_selection before it resolves loadouts, as min box create, min session start and min task run do after T126. Pin it in a crates/minimal dash test.
