* Move CommissionTiming and MechanismType into model.event packageKostya2026-08-2011-18/+18
| | | | | Groups them with the other event-domain enums instead of the general api package, and updates all call sites accordingly.
* Add MapStruct jars to service moduleKostya2026-08-201-0/+2
| | | | | | lib/*/*.jar is auto-globbed onto the build classpath, so this makes mapstruct available for future DTO<->domain mappers without any build script changes.
* Break down purchase receipts by cost/commission, harden XML validation and ↵Kostya2026-08-186-27/+485
| | | | | | | | | state I/O 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 subsidyKostya2026-08-189-16/+54
| | | | | | | | | | | | | - 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.
* Add XML schema validation, split build scripts by module, rename ↵Kostya2026-08-1817-34/+371
| | | | | | | | | BuyMenuCommand to PlaceOrderMenuCommand Introduces XMLValidatorV1 and deserializer/adapter classes for events, ledgers, markets, users, and trading mechanisms. Replaces the monolithic build.bat/run.sh scripts with per-module tools (_util.sh, build.sh, package.sh, test.sh) that compile in dependency order.
* Replace order matching with risk/matching/fulfillment/settlement pipelineKostya2026-08-1773-2151/+1995
| | | | | | | | | 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/matchingKostya2026-08-1620-226/+118
| | | | | | | 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 handlingKostya2026-08-1618-133/+295
| | | | | | Split GuessMarketContext into a separate CatalogContext for read-only event listing, wrap fallible operations in Result<T> instead of throwing, and wire load/save of events and users through a JSON Wrapper.
* Implement LMSR and order-book trading logic, wire MarketContext facade and ↵Kostya2026-08-1521-95/+358
| | | | | | | | | | | new menu commands Fill in the previously stubbed cost/pricing math for both trading mechanisms, and give OrderBookTradingMechanism an actual matching engine with resting bid/ask books. Fold EventRepository/UserRepository access into a single MarketContext used by LocalGuessMarketContext, and move the repository package under infrastructure. Add Buy/EventDetails/LoadState/ SaveState/SettleEvent console commands and wire them into App/Menu.
* Switch TradingMechanism quantities to int, add yes/no and select promptsKostya2026-08-143-6/+6
| | | | | | | | | TradingMechanism's q/quantity params move from long/long[] to int/int[] to match the rest of the domain (Trade.quantity, Option counts, etc. are already int). Add InputProcessor.readYesNo and readSelect for upcoming menu commands that need a confirm prompt or a pick-from-list prompt.
* Collapse console I/O interfaces into InputProcessor, drop unneeded atomicsKostya2026-08-143-8/+5
| | | | | | | | | | | InputProvider/OutputProvider each had one implementation and no test exercised the seam, so fold Console{Input,Output}Provider straight into InputProcessor and update Menu/MenuCommand call sites accordingly. Account and Event both use AtomicInteger for a ledger/trade id counter that's only ever touched next to a plain, non-thread-safe ArrayList add in the same method - the atomic bought no real thread-safety. Swapped both to plain int with ++.
* Implement in-memory repositories, XML load validation, and menu exit/list ↵Kostya2026-08-1413-53/+201
| | | | | | | | | | | | | | commands - Add generic Repository<T> interface; EventRepository/UserRepository extend it - Implement InMemoryEventRepository/InMemoryUserRepository backed by ArrayList - Rename XMLLoader to XMLLoaderV1, add LoadValidator and mapper/v2 package - Add OrderBookTradingMechanism - Add User(String, int) convenience constructor - Add ListEventsMenuCommand and ExitMenuCommand, isExit() on MenuCommand - Menu now sizes selection range by max command index and exits on isExit() - LoadFileMenuCommand reports validation issues on failed loads - Untrack test-data/ and config.properties from .gitignore
* Move mapper/provider infra into v1 packages, add repository write methodsKostya2026-08-148-17/+82
| | | | | Correct Mapper's generic parameter order to <TModel, TDomain> and stub addEvent/addUser on the Event/User repositories.
* Wire buyShares and menu commands, replace factory interfaces with DIKostya2026-08-148-5/+116
| | | | | | | | 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 ledgered credit/debit to Account and trade recording to EventKostya2026-08-146-26/+67
| | | | | | | Drops AccountType (accounts no longer need to self-identify), gives Account credit()/debit() that append LedgerEntry rows, adds Event.recordTrade()/tradeVolumeOf()/getCommission(), and implements LocalGuessMarketContext.listEvents() via the repository.
* Implement LMSR mechanism and Event/Account accessors, wire EventMapperV1Kostya2026-08-144-2/+176
| | | | | | Adds LmsrTradingMechanism, exposes Event/Account getters plus Event.toEventSummary() for DTO conversion, and implements EventMapperV1.toDomain() to build Event from the legacy XML model.
* Wire EventRepository into LocalGuessMarketContext, add mapper/provider infra ↵Kostya2026-08-147-3/+48
| | | | | | | and tests Removes the placeholder Mapper interface in favor of concrete mapper/provider implementations, fixes Menu.stop() to no-op instead of throwing.
* Add legacy XML model bindings, mapper infra, and normalize account balanceKostya2026-08-1328-4/+2277
| | | | | Rename repositories package to repository, add MarketAction domain type, and round Account.initialBalance through BigDecimalOptions.toMoney.
* Add domain model, repositories, and trading mechanism interfaces to service ↵Kostya2026-08-1311-0/+197
| | | | | | | module Introduces Account/Event/Trade/User/Option/LedgerEntry domain types plus EventRepository/UserRepository and TradingMechanism abstractions.
* Add service module with stubbed LocalGuessMarketContextKostya2026-08-133-0/+122
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.
