guess-market/service/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.

Add XML schema validation, split build scripts by module, rename BuyMenuCommand to PlaceOrderMenuCommand

2026-08-18T06:52:47Z

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 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.

Implement LMSR and order-book trading logic, wire MarketContext facade and new menu commands

2026-08-15T16:25:40Z

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 prompts

2026-08-14T20:54:31Z

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 atomics

2026-08-14T20:32:49Z

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 commands

2026-08-14T18:49:26Z

- Add generic Repository 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
