Add the session storage infrastructure for tracking correct answers
during a game. Designed for easy swap to Valkey in Phase 4.
- GameSessionStore interface with create/get/delete methods, all async
to match the eventual Valkey implementation
- InMemoryGameSessionStore backed by a Map
- GameSessionData holds only the answer key (questionId → correctOptionId)
- Also fix root build script to build packages in dependency order
Extend the game flow from raw term rows to a complete GameSession
matching the shared schema:
- Add getDistractors model query: fetches N same-POS, same-difficulty,
same-target-language terms excluding a given termId. Returns bare
strings since distractors only need their display text.
- Fix getGameTerms select clause to use the neutral field names
(sourceText, targetText, sourceGloss) that the type already declared.
- Rename gameService entry point to createGameSession; signature now
takes a GameRequest and returns a GameSession.
- Per question: fetch 3 distractors, combine with the correct answer,
shuffle (Fisher-Yates), assign optionIds 0-3 by post-shuffle index,
and assemble into a GameQuestion with a fresh UUID.
- Wrap the questions in a GameSession with its own UUID.
- Run per-question distractor fetches in parallel via Promise.all.
Known gap: the correct option is not yet remembered server-side, so
/game/answer cannot evaluate submissions. SessionStore lands next.
- Add GameRequestSchema and derived types to packages/shared
- Add SupportedLanguageCode, SupportedPos, DifficultyLevel type exports
- Add getGameTerms() model to packages/db with pos/language/difficulty/limit filters
- Add prepareGameQuestions() service skeleton in apps/api
- Add createGame controller with Zod safeParse validation
- Wire POST /api/v1/game/start route
- Add scripts/gametest/test-game.ts for manual end-to-end testing
- Configure PostgreSQL 18 and Valkey 9.1 services
- Create multi-stage Dockerfiles for API and Web apps
- Set up pnpm workspace support in container builds
- Configure hot reload via volume mounts for both services
- Add healthchecks for service orchestration
- Support dev/production stage targets (tsx watch vs compiled)
