What does it mean when a proposal is "held"?

The engine wanted to make the change, but a safety check stopped it. The most common are: stock cover not verified, so a bid raise is held; the term family has orders, so a negative is blocked; the item is inside its settle window.

Each held row states what would release it — usually a fresh inventory pull or more evidence. Some clear on their own next run.

Held is not the same as rejected. AutoPPC still thinks the change is right; it just will not act without the missing condition.
