An order does not belong to the address it came from

Why this is the important case

Accounts can be signed into again and messages can be resent. An order in progress is the thing a reader cannot reconstruct and cannot afford to be wrong about, which is why the fear attaches to it more strongly than anywhere else.

It is also the case where the mirror metaphor does the most damage, because a copy that goes stale is exactly the wrong mental model to bring to something that is in progress.

The structural answer

An order lives with the account and the market, not with the route the request came in on. The address is the path the instruction travelled down. Once the instruction has arrived, the path has no further part in it.

If that were not so, three addresses would be three separate markets that happened to share a name, and no reasonable use of the word mirror would apply.

What follows if an address goes quiet

• The order is not lost, cancelled or orphaned by the route becoming unavailable.
• You do not need that particular address to look at it again. Any route to the market is a route to the record.
• Nothing about the order needs moving, migrating or re-entering on another address.
• What you lose is a way in, and you had two others, which is the whole argument of what a second address buys you.

The genuine exception: things not yet submitted

An order you were in the middle of writing is a different object from an order you have placed. Text sitting in a form on a page is on the page. It has not reached anything and it does not exist anywhere but in front of you.

That is the one thing plurality can cost you, and it is covered properly in switching mid order. The boundary is submission, and it is sharp.

Why the fear persists anyway

Because the consequence of being wrong is large and the reasoning that settles it is abstract. A reader who is not sure will avoid the other two addresses while an order is open, which is precisely the period during which they most need a working route.

So the belief produces its own risk. Somebody waiting on an order, refusing to use the other two routes in case it disturbs something, has arranged to have exactly one way in during the week they can least afford to lose it.

What this study does not settle

It says nothing about how any order will go, how disputes are handled, or what any party will do. Those are questions about the market and this site has no view on them.

It settles one narrow thing: that the number of addresses is not a variable in any of it. An order placed through one route is the same order seen through another.

The rule

Submit, then move freely. Before submitting, finish or deliberately abandon. That single sentence covers everything plurality contributes to this subject, and everything else about orders belongs elsewhere.

Why this study is deliberately narrow

There is a great deal to say about orders and almost none of it is about the number of published addresses. Delivery, disputes, timing, what to expect: real subjects, and this site is not the place for any of them.

Keeping the study narrow is what makes it usable. A reader who arrives worried about an order and a quiet route gets one answer to one question, without having to sort it out of a general guide that is mostly about other things.

What this study is not. It is not advice about ordering, disputes or delivery, and nothing here is a claim about what happens after an order is placed.
