A shape can fit
and still fail the scan.

Seal a load

1. Select a piece on the cargo floor. Read its shape, weight, fragility, orientation, class, unload, bracing, and climate labels.
2. Rotate it if allowed, then choose its top-left anchor cell or drag it onto the container.
3. Read the handling scanner after each placement. Invalid overlap or bounds are rejected immediately; whole-load conflicts remain visible until resolved.
4. Place every piece with no active conflict, then seal the load for a mastery, density, checks, and handling-rules report.

Labels that change the puzzle

Foundations and backhaul contracts

The campaign is 24 separately authored loads. The 12 Dispatch foundations teach the handling rules on a rear-door bay. The 12 Backhaul contracts are new customers with their own bays, cargo, shapes, chilled zones, fixed load-restraint points, and a loading door on the front, left, or right instead. No load is another load turned, mirrored, or relabelled, and the campaign tests check that against every rotation and reflection of the bay. Use the manifest rack to replay any unlocked load. Daily slips generate a stable dated job; relief dispatch creates a deterministic, replayable load with variable bay dimensions.

The rules this bay really enforces

The handling-rules panel beside the container lists every rule that applies to the manifest in front of you, and marks each one met, breached, or not yet placed as you work. Nothing is checked only at seal time. The weight rule is narrow and worth reading carefully: a heavy piece may not sit in the row directly behind a fragile one. There is no separate rule that heavy pieces must sit low in the bay, so a heavy carton at the far end of the floor plan is a legal placement. First-drop cargo must touch the loading doors, braced pieces must reach a side wall, chilled pieces must stay wholly inside the blue zone, this-side-up pieces cannot be rotated, food and household chemicals must not touch, magnetic and electronic parcels must not touch, and fixed load-restraint points cannot be covered.

Reading a refusal

A refused placement names the rule it broke and then highlights every anchor cell where that piece does fit at its current turn, with a hatched mark and a plus, and states how many there are. Rotating, selecting another piece, undoing, or a successful placement clears the marks. If nothing is highlighted, the piece fits nowhere at that turn and needs rotating or another piece needs moving.

Rotating by touch

Rotation has an on-screen control as well as the bracket keys. The handling scanner carries a rotate button on the selected piece that names the angle it will turn to, alongside a readout of the current angle. This-side-up cargo shows the control disabled and says the rotation is locked.

What the sealed load shows

Sealing draws the finished bay twice. The top view is the bay from above with each piece in place, the loading-door edge marked, and × on every fixed load-restraint point. The side view lists the rows in unloading order, nearest the doors first, with each piece’s weight, fragility, and bracing, which is how the heavy-behind-fragile rule can be checked by eye. The report also states the par packing score for the manifest and one thing to try next.

Sealing, undo, and the walkthrough

Seal the load never does nothing. If a piece is still on the floor or a rule is breached, it says which piece and which rule, and the list under the button stays visible while you work. The packing score counts stowed volume, so it rises before the rules are satisfied; it is labelled provisional until every rule reads met. Undo and redo are free. The first load you open runs a four-step walkthrough that can be skipped and is never shown twice, and ? opens the keyboard reference at any time.
