model: relocate market DTOs out of the flat api package

2026-08-23T14:05:29Z

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.

Move CommissionTiming and MechanismType into model.event package

2026-08-20T09:09:20Z

Groups them with the other event-domain enums instead of the general api package, and updates all call sites accordingly.

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.

Fix menu wording and reprint prompt on retry

2026-08-18T07:37:50Z

Rename "option"/"but order" wording to "market"/"buy order", add a blank line before the command prompt, and reprint the prompt text on readInt() retries instead of leaving the user without context.

Harden console path input against crashes

2026-08-18T07:29:50Z

Menu.start() runs command.execute() with no surrounding try/catch, so an unchecked InvalidPathException from Path.of() on bad user input crashed the whole console loop. Centralize path parsing in InputProcessor.readPath(), which now validates and reprompts instead of throwing, and strips a surrounding pair of quotes so pasted/quoted paths still work.

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.
