definitely not polymarket https://git.sartin.in/guess-market/atom?h=2.0 2026-09-06T06:21:37Z 2026-09-06T06:21:37Z Kostya mail@sartin.in 2026-09-06T06:21:37Z urn:sha1:da82f3b492c3cd36f2e8723632a63a6cc1f4e39b The ex-2 schema describes a nested Guess-Market/GM-events document in which every event carries its pricing mechanism inline, as either a GM-LMSR element holding the liquidity parameter b or a GM-order-book element holding the allow-mint, initial and d attributes, instead of naming a mechanism and passing its parameters separately. Add the xjc-generated classes for that schema under catalog.model.v3, along with the fixtures the loader will be tested against: small.xml with two events, one per mechanism, multiple.xml with four, and two negative cases -- error-2.xml, where a market maker is funded with zero initial cash, and error-3.xml, where a market maker points at event id 12, which no event declares -- so the cross-reference and funding checks have something to reject. The binding covers the GM-events subtree only. The GM-users half of the document and the per-event id element are not bound yet, so nothing reads these classes so far.
