Handling rules

Handling rules define what counts as heavy and what as delicate, and the module orders both the route and the trolley accordingly. Without them a twenty-kilogram tin of paint collected at the first stop is carried through the rest of the wave.

Stockly → Warehouses → Rules → Handling.

Three classes

Class	Meaning
floor	heavy, the bottom of the stack
normal	ordinary
top	delicate, goes on top

The walk runs in the opposite direction to the load

This is intentional and not a defect.

Heavy goods go into the box first, because they form the base of the stack. They are collected last, so that they are not carried through the hall for the whole walk. There is no contradiction: the trolley has shelves, so the position of an item is determined by the shelf allocation and not by the moment it was picked.

In practice: delicate first, heavy last, and on the trolley the other way round.

Where the class comes from

A cascade; the first step that answers wins:

1. A handling rule, if one matches the article,
2. the packaging profile, if it names a Position in the carton,
3. the weight bands — above the heavy threshold floor, below the light one top,
4. normal, when nothing spoke.

The preview names the step that answered, which matters when looking for what to change: a top class derived from a weight threshold and a top class declared on the packaging profile look identical in a list.

An unknown weight is not a weight of zero

An article with no weight is ordinary, not light. An import writing 0.0 is routine, so a weight at or below zero counts as unknown too.

Otherwise every article without a measured weight would fall into the light band and be collected first, and one unfilled column would change the walking order across the whole warehouse.

A shop with no rules changes nothing

Until there is one active handling rule, the module assigns no classes: the route has a single partition and the trolley is loaded exactly as it was before this feature existed. Creating the first rule enables the mechanism; there is no separate switch.

The preview of the winning rule

Stockly → Warehouses → Rules → Handling → Preview.

Pick an article and optionally a warehouse, and the module asks the server for exactly the resolution the wave planning performs. The answer names the class, the cascade step that gave it, the criteria that matched and the weight; where there is no weight, it states that in words rather than leaving a blank.
