definitely not polymarket https://git.sartin.in/guess-market/atom?h=master 2026-09-06T09:22:58Z 2026-09-06T09:22:58Z Kostya mail@sartin.in 2026-09-06T09:22:58Z urn:sha1:5bc7c4ed9d052668af66d3116a6b7afbe62c6eec The desktop UI needs to create events, trade on both sides of an order book, and show who is participating in an event, none of which the api module could express so far. Add AccountContext for looking up ledger accounts by owner, and give CatalogContext an openEvent operation plus createEvent, taking either a CreateEventRequest or its fields spelled out. createEvent defaults to a "Not implemented" error so existing implementations keep compiling until they support it. Let GuessMarketContext.placeOrder take an explicit side, keeping the old signature as a default method that places a BUY so current callers are unaffected. Add OrderBookDTO and BookOrderDTO to describe per-option books with best bid, best ask and spread, and ParticipantDTO for a user's position, fees and P&L in an event. Carry the order books and participants on EventDetailDTO and the market maker's name on EventSummaryDTO. 2026-08-23T14:05:29Z Kostya mail@sartin.in 2026-08-23T14:05:29Z urn:sha1:843820ea9f357220d69f3795f3289ee41eed355c Move AccountDTO/MarketDTO/MarketStateDTO/PurchaseReceiptDTO/TradeRowDTO out of the catch-all api package into model.market (and LedgerDTO into model.ledger), matching the existing model.event convention so DTOs live next to the domain they describe rather than in the interface package. Relocate LedgerMapper from mapper.v2 to infrastructure.adapter to match the module's established package layout, and update all call sites and imports accordingly. Also register the ui-desktop module in the build tooling: add it to MODULES, add openjfx to the shipped runtime libs, and generalize package.sh so each executable module (ui-console, ui-desktop) gets its own Main-Class/Class-Path manifest and run script instead of special-casing ui-console. Fold long Class-Path manifest lines at 72 bytes per the JAR spec, since adding ui-desktop's dependencies pushed the line past the limit. 2026-08-20T09:09:20Z Kostya mail@sartin.in 2026-08-20T09:09:20Z urn:sha1:0fc488c3f9e29f5e9f1092f8081714c9e820f178 Groups them with the other event-domain enums instead of the general api package, and updates all call sites accordingly. 2026-08-18T09:07:57Z Kostya mail@sartin.in 2026-08-18T09:07:57Z urn:sha1:9dab2b3d624ecae08439532157fb8b9805fe9274 - Event ledger now grows on purchase and shrinks on payout, mirroring the exact amounts moved on the buyer's ledger (it previously had a Ledger object that nothing ever wrote to). - Settlement and event-detail views now show the winning market's display name instead of its raw key; event details are viewable for settled events too (the picker previously excluded anything not ACTIVE). - LMSR events seed their ledger with a SUBSIDY entry for the market maker's worst-case loss (b * ln(outcomes)), reusing the existing cost() function rather than recomputing the formula. 2026-08-16T18:50:15Z Kostya mail@sartin.in 2026-08-16T18:50:15Z urn:sha1:eed9265be711432f40247f149c07f9e33511192a Moves Event/Ledger DTOs out of the flat api package into api/model/{event,ledger}, and moves LocalCatalogContext and order matching logic into dedicated service/catalog and service/matching packages, replacing TradingOperation/TradingOperationImpl.
