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

lib/*/*.jar is auto-globbed onto the build classpath, so this makes
mapstruct available for future DTO<->domain mappers without any build
script changes.

Vendor jacocoagent.jar/jacococli.jar under lib/jacoco/ (excluded from
the shipped classpath), attach the agent during test runs, and
generate an HTML+XML report into build/coverage after tests pass.

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.

- 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.

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.

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.

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.

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.

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.
|
| |
|
|
|
|
| |
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.

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.
|

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.

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 ++.

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
|

Correct Mapper's generic parameter order to <TModel, TDomain> and stub
addEvent/addUser on the Event/User repositories.
|
| |
|
|
|
|
|

and file load command
Wires InputProcessor into the console menu's selection loop and the
load-file command's prompt handling, replacing the unimplemented stub.
|
| |
|
|
|
|
|
|
| |
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.
|

|

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.
|
| |
|
|
|
|
| |
Adds LmsrTradingMechanism, exposes Event/Account getters plus
Event.toEventSummary() for DTO conversion, and implements
EventMapperV1.toDomain() to build Event from the legacy XML model.
|
| |
|
|
|
|
|
| |
and tests
Removes the placeholder Mapper interface in favor of concrete mapper/provider
implementations, fixes Menu.stop() to no-op instead of throwing.
|
| |
|
|
|
| |
Rename repositories package to repository, add MarketAction domain type,
and round Account.initialBalance through BigDecimalOptions.toMoney.
|

module
Introduces Account/Event/Trade/User/Option/LedgerEntry domain types plus
EventRepository/UserRepository and TradingMechanism abstractions.

Superseded by the service module's GuessMarketContext implementation;
the JAXB model, TradingMechanism interface, and its LMSR/order-book
stubs had no remaining callers.
|
| |
|
|
|
|
|
|
|
|
| |
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.
|
| |
|
|
|
|
|
| |
Introduce MechanismType and rename CommissionChargeType to
CommissionTiming to better describe LMSR vs order-book events.
LocalGuessMarketContext.GetAllEventsAsync is stubbed pending the new
mapping.
|
| |
|
|
|
|
|
|

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.

PicoContainer wiring
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.

Move api, engine, ui-console and ui-desktop out of modules/ up to the
repo root and drop the empty exception project (GuessMarketException now
lives in api).
Vendor gson, jaxb, okhttp, openjfx and tomcat under lib/, and group the
JUnit standalone jar into lib/junit/ alongside them.
Rewrite every .classpath: drop the copy-pasted optional="true" that was
masking real build path errors, point the library entries at ../lib/,
and put the JUnit jar on the test source folders so the placeholder
AppTest classes compile.
ui-desktop: take the JavaFX jars off the modulepath (there is no
module-info.java, so module="true" left the packages unresolvable) and
add a Launcher that calls Application.launch, avoiding the "JavaFX
runtime components are missing" check without VM arguments.
engine: add LocalGuessMarketService and the GuessMarketContext provider
interface, and give GuessMarketException the no-arg and cause
constructors they need.
