Comparing offers across apps

Platform chips, the other books popover, exact lines versus alternate lines, over-only products, and when a price counts as published.

Two apps can post the same player and market and still be offering different things. Comparing them means matching the line, the side and the product before comparing the number.

Platform chips

The filter chips above the board are driven by the data on this slate, not by a fixed list. A book with no lines today has no chip, so a quiet feed never shows as an empty filter, and a book the product has switched off is absent everywhere a reader could meet it.

Exact line, not nearest line

A cross book comparison is only meaningful at one line. The product picks one row per book nearest the anchor line and says so, and it never blends prices from different lines into one average. An alternate rung is a different offer with a different probability, not a better price on the same one.

Example: Illustrative only

One app posts 1.5 total bases and another posts 0.5. These are not two prices for one offer. They are two offers, and the model's probability for each is computed at its own line.

The other books popover

Offers that do not sell the side shown, or that come from a book no feed attests, move behind an explicit disclosure control that lists each one with its real terms. They are a listing, never a second opinion supporting the row.

Over-only products

Many pick apps sell one side only. Reduced payout goblins and boosted payout demons are over-only by product rule, and plenty of ordinary offers are one sided too. The product locks those to the side the app sells, so an Under can never be published on an offer that has no Under, and a demon is never recommended.

When a price is published

A price counts as published only when the app's own feed carried it. Prices attached by an aggregator, and the screening multipliers the product uses internally, publish nothing: those rows print that the price is not published by the app, and no expected value is computed from them.
