What was actually published, and when.

A competitor's price, a supplier's stock, a marketplace rank. Unverifiable after the fact, until now. oddly commerce reads what storefronts publish, every tick, and keeps the value before and after every change with the receipt on each. The report is the record, read for your category.

The storefront markets

Every mark is a market we have read a storefront in.

A market with no storefront on the record draws nothing, and that absence is the honest half of the map.

This surface publishes no change count. A repeat is not a change, and on the record today no storefront has been observed twice, so there is nothing here to count and nothing worth borrowing from another class to fill the gap.

root [today's root]

That stamp is the newest observation anywhere on the ledger, and it is labelled as such because it is the only one a public read carries. It is not a claim that every storefront above was read on that date.

Down to one cell

A market is the easy part. The argument is one cell and its inputs.

A benchmark cell is not an opinion about a category. It is an arithmetic over prices that were published, each one read at a stated time, each one still reachable from the cell a year later.

What the decision rests on today

An assertion, handed over.

Every one of these is believed because of who supplied it. None of them can be checked by the person who has to act on it.

the screenshot

A screenshot is an assertion with a timestamp you typed. It proves you had a screen.

the export

A scraper's export has one clock and it is yours. Nobody can tell when the source said the number was true.

the report

A market report is someone's summary of what they saw, weeks ago, for everyone at once.

What oddly puts on the record

The same thing, observed.

Two clocks on every row: when the source said it was true, and when we looked. A root a day. An anchor outside us. Nothing here is our word.

storefronts

The storefronts across their markets, each read on its own cadence, each observation sealed with the one before it.

change

The changes on the record, each carrying the value before, the value after, both clocks and the receipt. A repeat is not a change and is not counted.

your category

A benchmark cell is computed from the published prices of the stores in it, and every cell reaches the observations it was computed from.

The verbs

Observe. Seal. Publish. Anchor.

The same four on every surface. A product here is the record read for one decision, never a second machine.

observe

Read the source as it is published, and write down both clocks.

seal

Hash the row with its predecessor, so no receipt can move without every later one changing.

publish

Fold the day's receipts into one root and put it where anyone can read it.

anchor

Submit the root to a chain we do not run. From then on, checking us does not involve us.

Every slot above is read at load and stays bracketed until a real value fills it. A row reads [unread] when the newest observation on the ledger belongs to another class, and the anchor reads [pending] until a day has been confirmed in a block, because a pending batch has no block height and printing one as anchored would be the worst thing this surface could do.
