Term: sheet
As people use the word, a sheet is the page itself. Someone curates a set of items, writes them into a public list and shares the address so others can read it. When they say "my sheet", they mean the page they have been keeping.
The word gets borrowed for private files too. A personal sheet is the same idea kept unshared: a running list of items opened, compared and shortlisted, built up over weeks. Either way the sheet is the container, not the products.
Term: spreadsheet
A spreadsheet is the format rather than the content. Rows and columns, item IDs in one field, prices in another, notes and image links further along. It is plain, editable and easy to copy, which is exactly why these lists spread the way they did.
The format carries one consequence worth naming. A spreadsheet holds whatever the person filling it decided to write down, so the columns you inherit describe their habits, not a standard. Two sheets can carry the same item and disagree on price, name and category.
Term: finds list
A finds list is what a sheet page usually is: items somebody found, judged worth ordering and decided to publish. The word "finds" is doing real work, because it tells you a person made those calls. Their picks, and their omissions, shape the list.
That matters the moment you inherit one from somebody else. The price beside an item is a snapshot taken the day it was added, and the category label is that person's opinion. Neither is a claim made by the seller or by any platform, so both are worth re-checking before you spend against them.
Term: agent
An agent is the platform that buys on your behalf, receives the parcel at its own warehouse and forwards it to you. It is a service, not a document, and it is the only piece of this stack with an account, a balance and terms attached to it.
ACBuy was that piece for this whole ledger. Purchasing stopped there on 12 June 2026 and never came back, which is why the platform ledger records it as closed, and why the words "my ACBuy sheet" usually mean the file rather than the service now.
How the four connect
The four pieces feed each other in a fixed order. Someone publishes a list of finds, somebody else copies it into a spreadsheet, the cells fill up with item IDs and wrapped addresses, and an agent hands out those wrapped addresses in the first place. The agent is the part that changes.
In the 31 wrapper records collected for snapshot 2026-W39, every source marker read WD, pointing at Weidian, and not one pointed anywhere else. Marketplace listings do not belong to whichever platform wrapped them, so an old sheet still resolves once you rebuild its addresses.
If you are working out where your own sheet sits in all this, start with the platform ledger to see which platforms are still open to new orders, then the open questions hub for the rest of these definitions and the terms that sit alongside them.
