RULE / OBSTACLES
Obstacles and clearance in 3D packing
Reserved volumes are geometry: unions of exact boxes approximate a wheel arch, a post or a roof shelf, and placements route around them.
obstacles + additional_boxesWhy it exists
The usable space is rarely the container envelope. Modelling the exclusion zone is what makes the result loadable in the vehicle you actually have.
What a useful refusal looks like
The engine returns the rule that refused, the item it refused, and the measured value against the configured threshold. It also states how strongly that is backed: proven, observed, inferred, or unknown because a search limit was reached first.

What this rule changes
One request, run twice by @packvium/engine while this page was built: once as written, once with only this rule taken out. The request diff is the whole input change; everything in the result diff follows from it.
