guess-market/api/src/main, branch 1.0

Break down purchase receipts by cost/commission, harden XML validation and state I/O

2026-08-18T15:19:50Z

Adds a full pre-load validation pass for GM XML seeds (ids, names, options, commission, LMSR liquidity), replaces IO.print with System.out, and surfaces detailed error messages across load/save commands instead of generic failures.

Wire event ledger movements, show winning market by name, seed LMSR subsidy

2026-08-18T09:07:57Z

- 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.

Replace order matching with risk/matching/fulfillment/settlement pipeline

2026-08-17T11:15:59Z

Move XML loading infrastructure and models under service/catalog, and split order execution into a real pipeline: RiskEngine checks the order, MatchingEngine matches it, FulfillmentContext books the resulting trades, and SettlementContext resolves winning markets. GuessMarketContext.buyShares becomes placeOrder(price, quantity), and TradingMechanism.buy now returns matched trades directly instead of a single TradeExecution.

Split DTOs into api/model, extract order matching into service/matching

2026-08-16T18:50:15Z

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.

Rename Option/Account to Market/Ledger, add Result-based error handling

2026-08-16T11:55:08Z

Split GuessMarketContext into a separate CatalogContext for read-only event listing, wrap fallible operations in Result instead of throwing, and wire load/save of events and users through a JSON Wrapper.

Wire buyShares and menu commands, replace factory interfaces with DI

2026-08-14T11:02:33Z

Implement LocalGuessMarketContext.buyShares/loadEvents via a new TradingOperation and Loader, backed by in-memory repositories. Replace the ConsoleInputProviderFactory/ConsoleOutputProviderFactory pattern with picocontainer-injected providers, and drive the menu from a list of MenuCommand implementations instead of a hardcoded printout.

Add service module with stubbed LocalGuessMarketContext

2026-08-13T16:24:24Z

GuessMarketContext gained a richer surface (loadEvents/listEvents/ buyShares/closeEvent/account/save-restoreState) backed by new EventDetailDTO, MarketStateDTO, OptionStateDTO and PurchaseReceiptDTO. The old engine-module provider implemented the previous shape and is removed; market.guess.service.LocalGuessMarketContext replaces it as a stub, each method throwing UnsupportedOperationException pending a real implementation.

Replace EventDTO with richer EventSummaryDTO/TradeRowDTO view models

2026-08-13T15:52:07Z

Introduce MechanismType and rename CommissionChargeType to CommissionTiming to better describe LMSR vs order-book events. LocalGuessMarketContext.GetAllEventsAsync is stubbed pending the new mapping.

Move I/O provider abstraction to ui-console, add ledger/account/problem DTOs

2026-08-13T15:39:56Z

InputProvider/OutputProvider were api-layer types only ever implemented by the console UI; relocate them there. Drop the unused GuessMarketEngine/LocalGuessMarketService pair, flesh out LoadResultDTO with success/failure variants, and make LocalGuessMarketContext.LoadAsync report real outcomes instead of an empty placeholder.

Move engine contracts to api module, add I/O provider abstraction and PicoContainer wiring

2026-08-10T20:21:55Z

Relocates GuessMarketEngine/GuessMarketContext into market.guess.api so engine and ui-console depend on a shared contract instead of engine internals, and makes context loading async (CompletableFuture). Adds InputProvider/OutputProvider interfaces with console implementations, wires the console app's Menu through a PicoContainer, and adds the generated model classes plus vendored picocontainer jar needed to build it.
