+# Schema strategy (dev) and persistence switching
+## Goal
+Keep the core domain independent from persistence details, while still providing a fast dev loop. Persistence and schema behavior are configured at the application boundary (the API app), not inside the domain.
+
+## Persistence modes (API runtime)
+The API supports two persistence modes, controlled by [`ProcessEnv.GRIDPILOT_API_PERSISTENCE`](apps/api/src/env.d.ts:7):
+
+- **`inmemory`**: no database required; the API runs with in-memory adapters.
+- **`postgres`**: the API uses Postgres via TypeORM.
+
+### Default inference (dev ergonomics)
+If `GRIDPILOT_API_PERSISTENCE` is **unset**, the API infers persistence from `DATABASE_URL` via [`getApiPersistence()`](apps/api/src/env.ts:33):
+
+- If `DATABASE_URL` is set → `postgres`
+- Otherwise → `inmemory`
+
+This is why dev compose should not hard-code `GRIDPILOT_API_PERSISTENCE`; it should allow inference unless explicitly overridden.
+
+## Schema strategy in development (TypeORM `synchronize`)
+When the API runs in Postgres mode, it loads [`DatabaseModule`](apps/api/src/domain/database/DatabaseModule.ts:1), which configures TypeORM with:
+
+- `synchronize: process.env.NODE_ENV !== 'production'` in [`TypeOrmModule.forRoot()`](apps/api/src/domain/database/DatabaseModule.ts:6)
+
+Practical meaning:
+- **Development/test:** TypeORM `synchronize` is enabled to keep schema aligned automatically during iteration.
+- **Production:** TypeORM `synchronize` is disabled.
+
+### Migrations (deferred)
+Migrations are intentionally deferred for now: local dev relies on `synchronize` for speed, while production-grade migrations will be introduced later at the infrastructure boundary (without changing the domain).
+
+## Switching modes locally
+### Docker dev (recommended)
+In [`docker-compose.dev.yml`](docker-compose.dev.yml:1), `GRIDPILOT_API_PERSISTENCE` should be optional so the default inference works.
+
+To force a mode, set one of:
+- `GRIDPILOT_API_PERSISTENCE=inmemory`
+- `GRIDPILOT_API_PERSISTENCE=postgres`
+
+Example environment reference (dev): [`DATABASE_URL`](.env.development.example:20) and optional persistence override (commented) in [`.env.development.example`](.env.development.example:17).
+
+## Dev seeding behavior (high level)
+Seeding/bootstrap runs at API startup via [`BootstrapModule`](apps/api/src/domain/bootstrap/BootstrapModule.ts:1), unless disabled with `GRIDPILOT_API_BOOTSTRAP=0` (parsed by [`getEnableBootstrap()`](apps/api/src/env.ts:49)).
+
+At startup:
+- Always runs `EnsureInitialData.execute()` in [`BootstrapModule.onModuleInit()`](apps/api/src/domain/bootstrap/BootstrapModule.ts:21).
+- Seeds racing data via `SeedRacingData` when:
+  - persistence is `inmemory`, or
+  - persistence is `postgres` AND `NODE_ENV !== 'production'` AND the racing DB appears empty (checked via the league repository) in [`BootstrapModule.shouldSeedRacingData()`](apps/api/src/domain/bootstrap/BootstrapModule.ts:42).
+
+This keeps dev environments usable without requiring manual seed steps, while avoiding unexpected reseeding in production.

+# Plan: Switch API persistence from InMemory to Postgres (TypeORM), keep InMemory for tests
+
+Timestamp: 2025-12-28T20:17:49Z  
+Scope: **Racing bounded context first**, dev switchable between InMemory and Postgres, tests keep forcing InMemory.
+
+## Goals
+- Make it **easy to switch** API persistence in dev via [`getApiPersistence()`](apps/api/src/env.ts:33) + [`process.env.GRIDPILOT_API_PERSISTENCE`](apps/api/src/env.d.ts:7).
+- Default dev flow supports Postgres via Docker, but does **not** force it.
+- Keep InMemory persistence intact and default for tests (already used in tests like [`process.env.GRIDPILOT_API_PERSISTENCE = 'inmemory'`](apps/api/src/domain/bootstrap/BootstrapSeed.http.test.ts:17)).
+- Implement Postgres/TypeORM persistence for **racing repositories** currently provided by [`InMemoryRacingPersistenceModule`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:72).
+- Provide **minimal idempotent seed** for Postgres so UI works (analogous to [`SeedRacingData`](apps/api/src/domain/bootstrap/BootstrapModule.ts:27)).
+
+## Current state (what’s wired today)
+- Env toggle exists: [`getApiPersistence()`](apps/api/src/env.ts:33).
+- Postgres wiring exists but incomplete: [`TypeOrmModule.forRoot()`](apps/api/src/domain/database/DatabaseModule.ts:6) with `entities` commented and `synchronize` enabled outside production ([`synchronize`](apps/api/src/domain/database/DatabaseModule.ts:18)).
+- Feature modules still hard-import in-memory racing persistence:
+  - [`LeagueModule`](apps/api/src/domain/league/LeagueModule.ts:8)
+  - [`RaceModule`](apps/api/src/domain/race/RaceModule.ts:8)
+  - [`DashboardModule`](apps/api/src/domain/dashboard/DashboardModule.ts:2)
+  - [`DriverModule`](apps/api/src/domain/driver/DriverModule.ts:2)
+  - [`ProtestsModule`](apps/api/src/domain/protests/ProtestsModule.ts:2)
+  - [`TeamModule`](apps/api/src/domain/team/TeamModule.ts:2)
+  - [`SponsorModule`](apps/api/src/domain/sponsor/SponsorModule.ts:2)
+  - [`BootstrapModule`](apps/api/src/domain/bootstrap/BootstrapModule.ts:11)
+- Dev compose currently forces InMemory even when `.env` provides `DATABASE_URL`:
+  - Forced: [`GRIDPILOT_API_PERSISTENCE=inmemory`](docker-compose.dev.yml:36)
+  - `.env` hints inference from `DATABASE_URL`: [`DATABASE_URL=postgres://...`](.env.development.example:20)
+
+## High-level approach
+1. Introduce a **persistence boundary module** for racing that selects implementation based on [`getApiPersistence()`](apps/api/src/env.ts:33).
+2. Implement a Postgres/TypeORM module for racing repos (same tokens as in-memory).
+3. Update racing-dependent API feature modules to import the boundary module (not the in-memory module).
+4. Add minimal Postgres seed (dev-only, idempotent).
+5. Fix dev compose to not hard-force InMemory.
+6. Verify with lint/types/tests.
+
+## Milestones (execution order)
+### M1 — Create racing persistence boundary (switch point)
+- Add [`RacingPersistenceModule`](apps/api/src/persistence/racing/RacingPersistenceModule.ts:1)
+  - `imports`: choose one of:
+    - [`InMemoryRacingPersistenceModule`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:72)
+    - New [`PostgresRacingPersistenceModule`](apps/api/src/persistence/postgres/PostgresRacingPersistenceModule.ts:1)
+  - `exports`: re-export the chosen module’s tokens, so downstream modules remain unchanged.
+
+Acceptance:
+- No feature module directly imports [`InMemoryRacingPersistenceModule`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:72) anymore.
+
+### M2 — Add Postgres racing persistence module (skeleton)
+- Add [`PostgresRacingPersistenceModule`](apps/api/src/persistence/postgres/PostgresRacingPersistenceModule.ts:1)
+  - Provides **the same tokens** defined in [`InMemoryRacingPersistenceModule`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:51):
+    - [`LEAGUE_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:52), [`RACE_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:53), etc.
+  - Uses `TypeOrmModule.forFeature([...entities])`.
+  - Must be compatible with DB root config in [`DatabaseModule`](apps/api/src/domain/database/DatabaseModule.ts:6).
+
+Acceptance:
+- API can start with `GRIDPILOT_API_PERSISTENCE=postgres` and resolve racing repository providers (even if repo methods are initially stubbed during iteration).
+
+### M3 — Implement first working slice (League + Season + Membership + Race as needed)
+- Implement ORM entities + mappers (ORM entities are not domain objects; follow clean architecture boundary from [`DOMAIN_OBJECTS.md`](docs/architecture/DOMAIN_OBJECTS.md:16)).
+- Implement TypeORM repositories for the minimal feature set used by:
+  - [`LeagueModule`](apps/api/src/domain/league/LeagueModule.ts:7)
+  - [`RaceModule`](apps/api/src/domain/race/RaceModule.ts:7)
+
+Strategy:
+- Start from the endpoints exercised by existing HTTP tests that currently force InMemory (e.g. league schedule/roster tests), but run them in InMemory first; then add a small Postgres-specific smoke test later if needed.
+
+Acceptance:
+- Core use cases depending on racing repos function against Postgres in dev.
+
+### M4 — Rewire feature modules to boundary module
+Replace imports of [`InMemoryRacingPersistenceModule`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:72) with [`RacingPersistenceModule`](apps/api/src/persistence/racing/RacingPersistenceModule.ts:1) in:
+- [`LeagueModule`](apps/api/src/domain/league/LeagueModule.ts:1)
+- [`RaceModule`](apps/api/src/domain/race/RaceModule.ts:1)
+- [`DashboardModule`](apps/api/src/domain/dashboard/DashboardModule.ts:1)
+- [`DriverModule`](apps/api/src/domain/driver/DriverModule.ts:1)
+- [`ProtestsModule`](apps/api/src/domain/protests/ProtestsModule.ts:1)
+- [`TeamModule`](apps/api/src/domain/team/TeamModule.ts:1)
+- [`SponsorModule`](apps/api/src/domain/sponsor/SponsorModule.ts:1)
+- plus adjust [`BootstrapModule`](apps/api/src/domain/bootstrap/BootstrapModule.ts:10) (see M5).
+
+Acceptance:
+- Switching env var changes racing persistence without touching module imports.
+
+### M5 — Minimal idempotent Postgres seed (dev UX)
+- Extend bootstrap so Postgres mode can seed minimal data when DB is empty.
+- Current bootstrap behavior only seeds racing data for InMemory: [`shouldSeedRacingData()`](apps/api/src/domain/bootstrap/BootstrapModule.ts:37).
+- Update logic to also seed for Postgres when:
+  - dev mode (non-prod), and
+  - tables empty (e.g., count leagues/drivers), and
+  - bootstrap enabled via [`getEnableBootstrap()`](apps/api/src/env.ts:49).
+
+Implementation note:
+- Seed code should remain adapter-level (reuse [`SeedRacingData`](apps/api/src/domain/bootstrap/BootstrapModule.ts:27)) but use repos from the active persistence module.
+
+Acceptance:
+- `docker compose -f docker-compose.dev.yml up` + `GRIDPILOT_API_PERSISTENCE=postgres` results in a usable UI without manual DB setup.
+
+### M6 — Dev compose/env ergonomics
+- Remove hard-coded forcing of InMemory in dev compose:
+  - Change/remove [`GRIDPILOT_API_PERSISTENCE=inmemory`](docker-compose.dev.yml:36)
+  - Prefer `.env.development` control, consistent with `.env example` guidance ([`DATABASE_URL`](.env.development.example:20)).
+
+Acceptance:
+- Devs can switch by editing `.env.development` or setting env override.
+
+### M7 — Verification gate
+Run:
+- `eslint`
+- `tsc`
+- tests
+
+Commands live in workspace scripts; start from package-level scripts as applicable (e.g. API tests via [`npm run test`](apps/api/package.json:10)).
+
+Acceptance:
+- No lint errors, no TypeScript errors, green tests (with default tests still using InMemory).
+
+## Out of scope (this pass)
+- Social persistence (stays InMemory for now).
+- Full migration system (placeholder remains, e.g. [`up()`](adapters/persistence/migrations/001_initial_schema.ts:5)).
+- Production-ready DB lifecycle (migrations, RLS, etc.).
+
+## Risks / watchouts
+- Provider scoping: racing repos are exported tokens; boundary module must avoid creating competing instances.
+- Entity design: ORM entities must not leak into core (enforce boundary per [`DOMAIN_OBJECTS.md`](docs/architecture/DOMAIN_OBJECTS.md:16)).
+- Bootstrap: ensure Postgres seed is idempotent and doesn’t run in production (align with `NODE_ENV` usage in [`DatabaseModule`](apps/api/src/domain/database/DatabaseModule.ts:18)).

+# Plan: Switch Racing persistence from InMemory to Postgres (TypeORM) while keeping InMemory for tests
+
+Timestamp: 2025-12-28T20:46:00Z  
+Scope: Racing bounded context persistence only (no Social/Identity/Media/Payments persistence changes)
+
+This plan is intentionally implementation-ready (what files to add, what to wire, what tests to write first) while keeping scope controlled: a minimal vertical slice that makes one meaningful League/Race workflow work in dev Postgres, but does not attempt to implement every Racing repository at once.
+
+---
+
+## 0) Context (current state, must preserve)
+
+- Persistence toggle is already defined at [`getApiPersistence()`](apps/api/src/env.ts:33) and typed in [`ProcessEnv`](apps/api/src/env.d.ts:3).
+- DB bootstrap exists as Nest module: [`DatabaseModule`](apps/api/src/domain/database/DatabaseModule.ts:1), with non-prod schema sync enabled via [`synchronize`](apps/api/src/domain/database/DatabaseModule.ts:18).
+- Racing repository tokens are currently defined in [`InMemoryRacingPersistenceModule`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:51) and are used as Nest provider tokens.
+- Persistence boundary already exists and selects between in-memory and Postgres: [`RacingPersistenceModule`](apps/api/src/persistence/racing/RacingPersistenceModule.ts:1).
+- Postgres wiring for Racing is currently placeholder-only: [`PostgresRacingPersistenceModule`](apps/api/src/persistence/postgres/PostgresRacingPersistenceModule.ts:51).
+- Clean Architecture rules to enforce (no ORM leakage into Core):
+  - [`DATA_FLOW.md`](docs/architecture/DATA_FLOW.md:1)
+  - [`DOMAIN_OBJECTS.md`](docs/architecture/DOMAIN_OBJECTS.md:1)
+  - File placement rules via [`FILE_STRUCTURE.md`](docs/architecture/FILE_STRUCTURE.md:1)
+
+---
+
+## 1) Goal and non-goals
+
+### Goal
+Enable Racing persistence via Postgres/TypeORM for development runtime (selected via [`getApiPersistence()`](apps/api/src/env.ts:33)), while keeping default test runs using in-memory persistence (to keep CI fast and deterministic).
+
+### Non-goals (explicit scope control)
+- No migration framework rollout, no production migration story beyond the existing non-prod `synchronize` behavior in [`DatabaseModule`](apps/api/src/domain/database/DatabaseModule.ts:18).
+- No broad refactors to use cases, DTOs, controllers, or domain modeling.
+- No implementation of non-Racing bounded contexts (Social/Identity/Media/etc).
+- No attempt to “finish all Racing repositories” in first pass; we will do a minimal vertical slice first.
+
+---
+
+## 2) Proposed adapter folder/file layout (TypeORM under `adapters/`)
+
+This follows the existing adapter organization shown in [`FILE_STRUCTURE.md`](docs/architecture/FILE_STRUCTURE.md:41) and the repo’s existing Racing adapter grouping under `adapters/racing/persistence/inmemory`.
+
+Create a parallel `typeorm` tree for Racing persistence:
+
+- `adapters/racing/persistence/typeorm/README.md`
+- `adapters/racing/persistence/typeorm/entities/`
+  - `LeagueOrmEntity.ts`
+  - `SeasonOrmEntity.ts`
+  - `LeagueScoringConfigOrmEntity.ts`
+  - `RaceOrmEntity.ts`
+  - `LeagueMembershipOrmEntity.ts`
+- `adapters/racing/persistence/typeorm/mappers/`
+  - `LeagueOrmMapper.ts`
+  - `SeasonOrmMapper.ts`
+  - `LeagueScoringConfigOrmMapper.ts`
+  - `RaceOrmMapper.ts`
+  - `LeagueMembershipOrmMapper.ts`
+- `adapters/racing/persistence/typeorm/repositories/`
+  - `TypeOrmLeagueRepository.ts`
+  - `TypeOrmSeasonRepository.ts`
+  - `TypeOrmLeagueScoringConfigRepository.ts`
+  - `TypeOrmRaceRepository.ts`
+  - `TypeOrmLeagueMembershipRepository.ts`
+- `adapters/racing/persistence/typeorm/testing/` (test-only helpers; never imported by prod code)
+  - `createTypeOrmTestDataSource.ts`
+  - `truncateRacingTables.ts`
+
+Notes:
+- Do not add any `index.ts` barrel files due to the lint restriction in [`.eslintrc.json`](.eslintrc.json:36).
+- All mapping logic must live in adapters (never in Core), per [`DATA_FLOW.md`](docs/architecture/DATA_FLOW.md:24).
+
+---
+
+## 3) Minimal vertical slice (useful and controlled)
+
+### 3.1 “Meaningful workflow” target
+Implement the smallest set that supports this end-to-end workflow in Postgres dev:
+
+1) Create a League (creates Season + scoring config) via the API call handled by the service method [`LeagueService.createLeague()`](apps/api/src/domain/league/LeagueService.ts:773) which uses [`CreateLeagueWithSeasonAndScoringUseCase`](core/racing/application/use-cases/CreateLeagueWithSeasonAndScoringUseCase.ts:56).  
+2) Fetch that League’s schedule (or races list) via [`GetLeagueScheduleUseCase`](core/racing/application/use-cases/GetLeagueScheduleUseCase.ts:33), used by [`LeagueService.getLeagueSchedule()`](apps/api/src/domain/league/LeagueService.ts:614).
+
+This is a practical vertical slice: it enables the admin UI to create a league and see a schedule scaffold.
+
+### 3.2 Repos/tokens INCLUDED in slice 1
+Implement Postgres/TypeORM repositories for the following tokens from [`InMemoryRacingPersistenceModule`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:51):
+
+- [`LEAGUE_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:52) → `TypeOrmLeagueRepository`
+- [`SEASON_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:62) → `TypeOrmSeasonRepository`
+- [`LEAGUE_SCORING_CONFIG_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:64) → `TypeOrmLeagueScoringConfigRepository`
+- [`RACE_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:53) → `TypeOrmRaceRepository`
+- [`LEAGUE_MEMBERSHIP_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:56) → `TypeOrmLeagueMembershipRepository`
+
+Rationale:
+- Creation flow requires the first three via [`CreateLeagueWithSeasonAndScoringUseCase`](core/racing/application/use-cases/CreateLeagueWithSeasonAndScoringUseCase.ts:56).
+- Schedule flow requires `league`, `season`, `race` repos via [`GetLeagueScheduleUseCase`](core/racing/application/use-cases/GetLeagueScheduleUseCase.ts:33).
+- Capacity listing and “join league” depend on membership repo via [`GetAllLeaguesWithCapacityUseCase`](core/racing/application/use-cases/GetAllLeaguesWithCapacityUseCase.ts:25) and [`JoinLeagueUseCase`](core/racing/application/use-cases/JoinLeagueUseCase.ts:18).
+
+### 3.3 Repos/tokens DEFERRED (slice 2+)
+Explicitly defer these tokens from [`InMemoryRacingPersistenceModule`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:51) to later phases:
+
+- [`DRIVER_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:51)
+- [`RESULT_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:54)
+- [`STANDING_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:55)
+- [`RACE_REGISTRATION_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:57)
+- [`TEAM_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:58)
+- [`TEAM_MEMBERSHIP_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:59)
+- Anything sponsorship/wallet-related in Racing persistence (tokens near [`LEAGUE_WALLET_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:66))
+
+This keeps slice 1 focused and prevents exploding schema surface area.
+
+---
+
+## 4) Mapping strategy (ORM entities vs domain entities)
+
+### 4.1 Boundary rule (non-negotiable)
+Core domain entities (example [`League`](core/racing/domain/entities/League.ts:93), [`Race`](core/racing/domain/entities/Race.ts:18)) MUST NOT import or refer to ORM entities, repositories, decorators, or TypeORM types, per [`DOMAIN_OBJECTS.md`](docs/architecture/DOMAIN_OBJECTS.md:16) and [`DATA_FLOW.md`](docs/architecture/DATA_FLOW.md:24).
+
+### 4.2 ORM entity design principles
+- ORM entities are persistence models optimized for storage/querying and can use primitives (string, number, Date) and JSON columns.
+- Domain entities use rich value objects and invariants and should be built using existing factories like [`League.create()`](core/racing/domain/entities/League.ts:132) and [`Race.create()`](core/racing/domain/entities/Race.ts:81).
+
+### 4.3 Mapping responsibilities
+Mapping lives in `adapters/racing/persistence/typeorm/mappers/*` and is responsible for:
+
+- `toDomain(orm)`:
+  - Convert primitive columns/JSON back into domain props.
+  - Call domain factory methods (`create`) with validated values.
+  - Handle optional fields and backward-compatibility defaults (e.g., `League.settings` in [`League`](core/racing/domain/entities/League.ts:72)).
+- `toOrm(domain)`:
+  - Convert domain value objects to primitives suitable for columns.
+  - Define canonical serialization for nested structures (e.g., store `League.settings` as JSONB).
+
+### 4.4 Proposed per-entity mapping notes (slice 1)
+
+#### League
+- Persist fields:
+  - `id` string (PK)
+  - `name` string
+  - `description` string
+  - `ownerId` string
+  - `createdAt` Date
+  - `settings` JSONB (store `LeagueSettings` from [`LeagueSettings`](core/racing/domain/entities/League.ts:72))
+  - `socialLinks` JSONB nullable
+  - `participantCount` integer (if needed; domain tracks via internal `_participantCount` in [`League`](core/racing/domain/entities/League.ts:103))
+  - `visibility` string (redundant to settings.visibility, but may be useful for querying; keep either:
+    - Option A: derive from settings only and do not store separate column
+    - Option B: store both and enforce consistency in mapper (preferred for query ergonomics)
+
+#### Season
+- Keep Season as its own ORM entity with FK to leagueId (string).
+- Use JSONB for schedule (if schedule is a complex object), and scalar columns for status, year, order, start/end.
+
+#### LeagueScoringConfig
+- Store `seasonId` string as unique FK.
+- Store scoring config payload (championships, points tables, bonus rules) as JSONB.
+
+#### Race
+- Persist scalar fields corresponding to [`Race`](core/racing/domain/entities/Race.ts:18):
+  - `id` string (PK)
+  - `leagueId` string (indexed)
+  - `scheduledAt` timestamptz
+  - `track`, `trackId`, `car`, `carId` strings
+  - `sessionType` string
+  - `status` string (from [`RaceStatus`](core/racing/domain/entities/Race.ts:11))
+  - `strengthOfField`, `registeredCount`, `maxParticipants` integers nullable
+- Queries required by Core ports (examples in [`IRaceRepository`](core/racing/domain/repositories/IRaceRepository.ts:10)):
+  - find by leagueId
+  - upcoming/completed filtering (status + scheduledAt)
+
+#### LeagueMembership
+- Persist fields corresponding to [`LeagueMembership`](core/racing/domain/entities/LeagueMembership.ts:25):
+  - `id` string (domain uses default `${leagueId}:${driverId}` in [`LeagueMembership.create()`](core/racing/domain/entities/LeagueMembership.ts:49))
+  - `leagueId` string (indexed)
+  - `driverId` string (indexed)
+  - `role` string
+  - `status` string
+  - `joinedAt` timestamptz
+- This enables membership queries required by [`ILeagueMembershipRepository`](core/racing/domain/repositories/ILeagueMembershipRepository.ts:13).
+
+---
+
+## 5) TypeORM + Nest wiring specifics
+
+### 5.1 Database root config
+Current `DatabaseModule` uses [`TypeOrmModule.forRoot()`](apps/api/src/domain/database/DatabaseModule.ts:6) and does not register entities.
+
+Plan change (minimal and controlled):
+- Update [`DatabaseModule`](apps/api/src/domain/database/DatabaseModule.ts:1) to support loading Racing entities when Postgres persistence is enabled:
+  - Add `autoLoadEntities: true` in the `forRoot` options so entities registered via feature modules are discovered.
+  - Keep [`synchronize`](apps/api/src/domain/database/DatabaseModule.ts:18) behavior as-is for non-prod for now (explicitly acknowledged technical debt).
+
+Why:
+- We want Racing persistence to be modular (entities registered only when the Postgres Racing module is imported) without a global “list every entity in the world” change.
+
+### 5.2 Postgres Racing module structure
+Replace placeholder providers in [`PostgresRacingPersistenceModule`](apps/api/src/persistence/postgres/PostgresRacingPersistenceModule.ts:51) with real wiring:
+
+- `imports`:
+  - [`LoggingModule`](apps/api/src/persistence/postgres/PostgresRacingPersistenceModule.ts:3) (already present)
+  - Nest TypeORM feature registration for the slice 1 entities:
+    - `TypeOrmModule.forFeature([LeagueOrmEntity, SeasonOrmEntity, LeagueScoringConfigOrmEntity, RaceOrmEntity, LeagueMembershipOrmEntity])`
+      - Mentioned as a method name; `TypeOrmModule` itself is already in use at [`TypeOrmModule.forRoot()`](apps/api/src/domain/database/DatabaseModule.ts:6).
+
+- `providers`:
+  - Register each repository implementation class under the existing tokens, matching the in-memory token names exactly (examples in [`InMemoryRacingPersistenceModule`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:75)):
+    - Provide [`LEAGUE_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:52) → `TypeOrmLeagueRepository`
+    - Provide [`SEASON_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:62) → `TypeOrmSeasonRepository`
+    - Provide [`LEAGUE_SCORING_CONFIG_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:64) → `TypeOrmLeagueScoringConfigRepository`
+    - Provide [`RACE_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:53) → `TypeOrmRaceRepository`
+    - Provide [`LEAGUE_MEMBERSHIP_REPOSITORY_TOKEN`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:56) → `TypeOrmLeagueMembershipRepository`
+
+- `exports`:
+  - Export the same tokens so downstream modules remain unchanged, mirroring the export list pattern in [`InMemoryRacingPersistenceModule`](apps/api/src/persistence/inmemory/InMemoryRacingPersistenceModule.ts:182).
+
+### 5.3 Repository implementation style
+Each `TypeOrm*Repository`:
+- Implements the relevant Core repository interface, e.g. [`ILeagueRepository`](core/racing/domain/repositories/ILeagueRepository.ts:10).
+- Depends only on:
+  - TypeORM repository/DataSource types (adapter-layer OK)
+  - Mappers in adapters
+  - Domain entities/ports (core-layer OK)
+- Does not expose ORM entities outside adapters.
+
+### 5.4 Persistence boundary selection remains the same
+Do not change selection semantics in [`RacingPersistenceModule`](apps/api/src/persistence/racing/RacingPersistenceModule.ts:7). This module already selects Postgres vs in-memory using [`getApiPersistence()`](apps/api/src/env.ts:33).
+
+---
+
+## 6) TDD-first phased rollout (tests first, controlled scope)
+
+### 6.1 Testing goals
+- Add confidence that TypeORM repositories satisfy Core port contracts.
+- Keep default test runs fast and in-memory by default.
+- Add Postgres-backed integration tests that are opt-in (run only when explicitly enabled).
+
+### 6.2 What tests already exist and should remain green
+- Persistence module selection test: [`RacingPersistenceModule.test.ts`](apps/api/src/persistence/racing/RacingPersistenceModule.test.ts:9) (currently asserts placeholder instance in Postgres mode). This will need updating once placeholders are replaced, but the intent remains valid.
+- Existing in-memory repository unit tests under `adapters/racing/persistence/inmemory/*.test.ts` (example: [`InMemoryLeagueRepository.test.ts`](adapters/racing/persistence/inmemory/InMemoryLeagueRepository.test.ts)) must remain untouched and continue to run by default.
+
+### 6.3 New tests to write first (TDD sequence)
+
+#### Phase A: Contract-style repo tests for TypeORM (integration tests, opt-in)
+Create a new test suite for each TypeORM repository in:
+- `adapters/racing/persistence/typeorm/repositories/*Repository.integration.test.ts`
+
+Test approach:
+- Use a real Postgres database (not mocks) and TypeORM DataSource configured similarly to runtime config in [`DatabaseModule`](apps/api/src/domain/database/DatabaseModule.ts:6).
+- Keep these tests skipped unless a flag is set, e.g. `RUN_RACING_PG_TESTS=1` (exact naming to be decided in implementation mode).
+- Use a dedicated DB name or schema per run and truncate tables between tests.
+
+Example test cases (for slice 1):
+- `TypeOrmLeagueRepository` should satisfy basic operations defined in [`ILeagueRepository`](core/racing/domain/repositories/ILeagueRepository.ts:10):
+  - create + findById roundtrip
+  - findAll returns inserted
+  - update roundtrip
+  - exists works
+- `TypeOrmSeasonRepository` should satisfy [`ISeasonRepository`](core/racing/domain/repositories/ISeasonRepository.ts:3):
+  - create + findById
+  - findByLeagueId
+- `TypeOrmRaceRepository` should satisfy [`IRaceRepository`](core/racing/domain/repositories/IRaceRepository.ts:10):
+  - create + findById
+  - findByLeagueId
+  - findUpcomingByLeagueId and findCompletedByLeagueId behavior (status + date)
+- `TypeOrmLeagueMembershipRepository` should satisfy [`ILeagueMembershipRepository`](core/racing/domain/repositories/ILeagueMembershipRepository.ts:13):
+  - saveMembership + getMembership
+  - getLeagueMembers filtering (active vs pending) must match whatever domain expects (start with minimal “returns all stored” behavior, then align with use cases)
+- `TypeOrmLeagueScoringConfigRepository` should satisfy [`ILeagueScoringConfigRepository`](core/racing/domain/repositories/ILeagueScoringConfigRepository.ts:3):
+  - save + findBySeasonId
+
+Why integration tests first:
+- It forces us to design the ORM schema + mapping in a way that matches the Core port contracts immediately.
+
+#### Phase B: Update module selection test (unit test, always-on)
+Update [`RacingPersistenceModule.test.ts`](apps/api/src/persistence/racing/RacingPersistenceModule.test.ts:9) to assert that in Postgres mode the provider resolves to the real TypeORM repo class (instead of the placeholder in [`PostgresRacingPersistenceModule`](apps/api/src/persistence/postgres/PostgresRacingPersistenceModule.ts:30)).
+
+This remains a fast unit test: it only checks Nest DI wiring, not DB behavior.
+
+### 6.4 What to mock vs run “for real”
+- Mock nothing for repository integration tests (they should hit Postgres).
+- Keep Core use case tests (if any exist) running with in-memory repos or test doubles by default.
+- Do not switch existing HTTP tests to Postgres by default (many explicitly set in-memory via env in files like those discovered under `apps/api/src/domain/league/*.http.test.ts` via earlier repo search).
+
+### 6.5 Keeping default tests in in-memory mode
+- Preserve the current default behavior where tests set [`GRIDPILOT_API_PERSISTENCE`](apps/api/src/env.d.ts:7) to `inmemory` (example in [`RacingPersistenceModule.test.ts`](apps/api/src/persistence/racing/RacingPersistenceModule.test.ts:20)).
+- Ensure the Postgres integration tests are opt-in and not included in default `npm run api:test` from [`apps/api/package.json`](apps/api/package.json:10).
+
+---
+
+## 7) Dev bootstrap/seed strategy for Postgres (minimal, idempotent, non-test)
+
+### 7.1 Current behavior
+Bootstrap currently seeds racing data only in in-memory mode via [`shouldSeedRacingData()`](apps/api/src/domain/bootstrap/BootstrapModule.ts:37), which returns `true` only for `inmemory`.
+
+### 7.2 Target behavior
+In dev Postgres mode, seed minimal Racing data only when the database is empty, and never during tests.
+
+Proposed logic change in [`BootstrapModule`](apps/api/src/domain/bootstrap/BootstrapModule.ts:10):
+- Seed when ALL are true:
+  - `NODE_ENV !== 'production'`
+  - persistence is Postgres via [`getApiPersistence()`](apps/api/src/env.ts:33)
+  - database appears empty for Racing (fast check: `driverRepository.findAll().length === 0` as already used in [`SeedRacingData.execute()`](adapters/bootstrap/SeedRacingData.ts:55))
+  - bootstrap is enabled (already toggled globally in app startup via [`getEnableBootstrap()`](apps/api/src/env.ts:49) and [`AppModule`](apps/api/src/app.module.ts:29))
+
+Implementation detail:
+- Keep using [`SeedRacingData`](adapters/bootstrap/SeedRacingData.ts:49) because it is already idempotent-ish (it skips when drivers exist at [`SeedRacingData.execute()`](adapters/bootstrap/SeedRacingData.ts:55)).
+- Ensure Postgres-backed `driverRepository` is not required for slice 1 if we keep seed minimal; however, current seed checks drivers first, so this implies either:
+  - Option A (preferred for UI usefulness): include Driver repo in Postgres slice 1b (small extension) so seeding can run fully, or
+  - Option B (controlled scope): create a Postgres-only “minimal seed” class that checks `leagueRepository.findAll()` instead of drivers and seeds only leagues/seasons/races/memberships/scoring configs.
+
+To keep scope controlled and aligned with “Racing only”, choose Option B for slice 1:
+- Introduce `SeedRacingDataMinimal` under `adapters/bootstrap/racing/` that seeds:
+  - one league
+  - one active season
+  - 0..N races in the season window
+  - one membership for the owner (so capacity endpoints have meaningful data)
+  - one scoring config for the active season
+- Keep it idempotent:
+  - skip if `leagueRepository.findAll()` returns any leagues
+  - upsert behavior for scoring config by seasonId (align with [`ILeagueScoringConfigRepository.findBySeasonId()`](core/racing/domain/repositories/ILeagueScoringConfigRepository.ts:3))
+
+Test contamination avoidance:
+- Tests already default to in-memory persistence and can also set `GRIDPILOT_API_BOOTSTRAP` to false if needed via [`getEnableBootstrap()`](apps/api/src/env.ts:49).
+
+---
+
+## 8) Dev ergonomics: docker-compose dev toggle change (exact change)
+
+### 8.1 Current issue
+`docker-compose.dev.yml` forces in-memory persistence via [`GRIDPILOT_API_PERSISTENCE=inmemory`](docker-compose.dev.yml:36), which overrides the inference behavior in [`getApiPersistence()`](apps/api/src/env.ts:33).
+
+### 8.2 Proposed exact change (minimal)
+Update [`docker-compose.dev.yml`](docker-compose.dev.yml:26) to stop hard-forcing in-memory:
+
+- Replace the hard-coded line at [`docker-compose.dev.yml`](docker-compose.dev.yml:36) with:
+  - `- GRIDPILOT_API_PERSISTENCE=${GRIDPILOT_API_PERSISTENCE:-postgres}`
+
+Expected dev behavior:
+- Default dev stack uses Postgres persistence (because compose default becomes `postgres`).
+- Developers can still run in-memory explicitly by setting `GRIDPILOT_API_PERSISTENCE=inmemory` before running the compose command.
+
+Alternative (if you prefer to preserve auto-detection):
+- Remove the line entirely and rely on [`getApiPersistence()`](apps/api/src/env.ts:33) + `DATABASE_URL` presence in `.env.development`.
+
+This plan recommends the explicit compose default approach because it is more deterministic and avoids hidden coupling to `.env.development` contents.
+
+---
+
+## 9) Phased implementation plan (step-by-step)
+
+### Phase 1: Prepare TypeORM adapter skeleton (no behavior change)
+1) Add the folder structure described in section 2.
+2) Add the ORM entity files for the slice 1 domain models with minimal columns and constraints (PKs, required columns, basic indices).
+3) Add mapper stubs with round-trip intent documented.
+4) Add repository class stubs that implement the Core interfaces but throw “not implemented” only for methods not used in slice 1 tests.
+
+Gate:
+- No changes to runtime wiring yet; existing tests remain green.
+
+### Phase 2: Add opt-in Postgres integration tests (TDD)
+1) Add TypeORM DataSource test helper.
+2) Write failing integration tests for `TypeOrmLeagueRepository` and implement it until green.
+3) Repeat for `Season`, `Race`, `Membership`, `ScoringConfig` repos.
+
+Gate:
+- Integration tests pass when enabled.
+- Default `npm run api:test` remains unaffected.
+
+### Phase 3: Wire Postgres Racing module to real repos (DI correctness)
+1) Update [`PostgresRacingPersistenceModule`](apps/api/src/persistence/postgres/PostgresRacingPersistenceModule.ts:51):
+   - Import TypeORM feature registration (section 5.2).
+   - Replace placeholder providers with real repository providers for slice 1 tokens.
+2) Update [`RacingPersistenceModule.test.ts`](apps/api/src/persistence/racing/RacingPersistenceModule.test.ts:9) to assert the Postgres providers resolve to the real TypeORM repo classes (instead of placeholders).
+
+Gate:
+- Always-on module selection tests pass.
+
+### Phase 4: Enable dev Postgres UX (bootstrap + compose)
+1) Update [`BootstrapModule`](apps/api/src/domain/bootstrap/BootstrapModule.ts:10) to seed minimal Racing data in dev Postgres mode only when empty.
+2) Update [`docker-compose.dev.yml`](docker-compose.dev.yml:26) per section 8.
+
+Gate:
+- `docker compose` dev stack can run with Postgres persistence and UI has minimal data.
+
+### Phase 5: Incrementally expand beyond slice 1 (future, explicitly not required to finish now)
+Add Driver + Result + Standings etc only when a concrete UI/endpoint requires them and after writing the next integration tests first.
+
+---
+
+## 10) Verification gates (exact commands and when)
+
+Run these at the end of each phase that changes TS code:
+
+- ESLint:
+  - `npm run lint` (script defined at [`package.json`](package.json:80))
+- TypeScript:
+  - `npm run typecheck:targets` (script defined at [`package.json`](package.json:120))
+- API tests:
+  - `npm run api:test` (script defined at [`package.json`](package.json:64)) or `npm run test --workspace=@gridpilot/api` via [`apps/api/package.json`](apps/api/package.json:10)
+
+For opt-in Postgres repository integration tests (added in Phase 2):
+- Define a dedicated command (implementation-mode decision), but the plan expects it to be an explicit command that developers run intentionally (not part of default CI).
+
+---
+
+## 11) Risks and mitigations
+
+- Risk: ORM entities leak into Core through shared types.
+  - Mitigation: enforce mappers in adapters only, keep interfaces as Core ports (example [`ILeagueRepository`](core/racing/domain/repositories/ILeagueRepository.ts:10)).
+- Risk: Seed logic contaminates tests.
+  - Mitigation: preserve default in-memory persistence in tests (example env usage in [`RacingPersistenceModule.test.ts`](apps/api/src/persistence/racing/RacingPersistenceModule.test.ts:20)) and gate seeding by non-prod + emptiness checks; tests can disable bootstrap via [`getEnableBootstrap()`](apps/api/src/env.ts:49).
+- Risk: TypeORM entity registration not picked up because entities not configured.
+  - Mitigation: enable `autoLoadEntities` in [`DatabaseModule`](apps/api/src/domain/database/DatabaseModule.ts:1) as part of implementation.
+
+---
+
+## 12) Ready-for-approval questions (for implementation mode to resolve quickly)
+
+These are the only decisions that materially affect implementation detail:
+
+1) Prefer Postgres integration tests using a developer-managed Postgres (via `DATABASE_URL`) or a dedicated docker-compose test database?
+2) For slice 1 seed, should we implement a minimal Racing-only seed (recommended) or extend slice 1 to include Driver repo so we can reuse [`SeedRacingData`](adapters/bootstrap/SeedRacingData.ts:49) unchanged?

+# Racing TypeORM Adapter Clean Architecture Audit + Strict Refactor Guide
+
+Scope focus: all persistence adapter code under [`adapters/racing/persistence/typeorm/`](adapters/racing/persistence/typeorm:1), especially mappers (incl. JSON mappers) and repositories, plus the ORM entities and adapter-scoped errors they depend on.
+
+This guide is intentionally strict and implementation-ready.
+
+---
+
+## Governing constraints (authoritative)
+
+- **Strict inward dependencies**: [`Only dependency-inward is allowed.`](docs/architecture/DATA_FLOW.md:24)
+- **Domain purity / no IO in domain objects**: [`Entities MUST NOT perform IO.`](docs/architecture/DOMAIN_OBJECTS.md:49)
+- **Persisted objects must rehydrate, not create**: [`Existing entities are reconstructed via rehydrate().`](docs/architecture/DOMAIN_OBJECTS.md:57)
+- **Adapters translate only (no orchestration/business logic)**: [`Adapters translate.`](docs/architecture/DATA_FLOW.md:437)
+- **Persistence entity placement**: ORM entities live in adapters, not domain: [`entities/ ORM-Entities (nicht Domain!)`](docs/architecture/FILE_STRUCTURE.md:47)

+
+### Adapter-scoped errors
+- [`InvalidLeagueScoringConfigChampionshipsSchemaError`](adapters/racing/persistence/typeorm/errors/InvalidLeagueScoringConfigChampionshipsSchemaError.ts:1)
+
+---
+
+## Concrete violations (file + function, why, severity)
+
+Severity rubric:
+- **Blocker**: violates non-negotiable constraints; can cause domain invariants to run on persisted state, or leaks construction/orchestration into adapters.
+- **Follow-up**: does not strictly violate constraints, but is unsafe/unclear and should be corrected to align with the canonical strict pattern defined below.
+
+### 1) Rehydration violations (calling `create()` when loading from DB) — **Blocker**
+
+- [`LeagueOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/LeagueOrmMapper.ts:46)
+  - **Why**: Uses [`League.create()`](core/racing/domain/entities/League.ts:132) for persisted reconstruction.
+  - **Rule violated**: persisted objects must reconstruct via [`rehydrate()`](docs/architecture/DOMAIN_OBJECTS.md:57) semantics (new vs existing).
+  - **Impact**: running creation-time defaulting + validation on persisted state can mutate meaning (e.g., defaults merged in [`League.create()`](core/racing/domain/entities/League.ts:132)) and can throw domain validation errors due to persistence schema drift.
+
+- [`RaceOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/RaceOrmMapper.ts:23)
+  - **Why**: Uses [`Race.create()`](core/racing/domain/entities/Race.ts:81) for persisted reconstruction.
+  - **Rule violated**: persisted objects must reconstruct via [`rehydrate()`](docs/architecture/DOMAIN_OBJECTS.md:57).
+  - **Impact**: DB rows become subject to “new entity” validations; adapter loses ability to separate “invalid persisted schema” (adapter concern) from “invalid new command” (domain concern).
+
+- [`SeasonOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/SeasonOrmMapper.ts:26)
+  - **Why**: Uses [`Season.create()`](core/racing/domain/entities/season/Season.ts:70) for persisted reconstruction.
+  - **Rule violated**: persisted objects must reconstruct via [`rehydrate()`](docs/architecture/DOMAIN_OBJECTS.md:57).
+  - **Impact**: same as above, plus schedule/scoring/drop/stewarding props are passed as `any`, making persisted-state validation unpredictable.
+
+- Positive control (already compliant): [`LeagueScoringConfigOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/LeagueScoringConfigOrmMapper.ts:54)
+  - Uses [`LeagueScoringConfig.rehydrate()`](core/racing/domain/entities/LeagueScoringConfig.ts:63) and validates schema before converting.
+  - This is the baseline pattern to replicate.
+
+### 2) Adapter “translation only” violations (construction / orchestration inside repositories) — **Blocker**
+
+- [`TypeOrmLeagueRepository.constructor()`](adapters/racing/persistence/typeorm/repositories/TypeOrmLeagueRepository.ts:10)
+  - **Why**: Default-constructs a mapper via `new` ([`new LeagueOrmMapper()`](adapters/racing/persistence/typeorm/repositories/TypeOrmLeagueRepository.ts:12)).
+  - **Rule violated**: adapters must “translate only” ([`Adapters translate.`](docs/architecture/DATA_FLOW.md:437)); object graph construction belongs in the composition root (Nest module).
+  - **Impact**: makes DI inconsistent, harder to test, and encourages mapper graphs to be built ad-hoc in infrastructure code rather than composed centrally.
+
+- [`TypeOrmRaceRepository.constructor()`](adapters/racing/persistence/typeorm/repositories/TypeOrmRaceRepository.ts:10)
+  - **Why**: Default-constructs mapper via [`new RaceOrmMapper()`](adapters/racing/persistence/typeorm/repositories/TypeOrmRaceRepository.ts:12).
+  - **Rule violated**: [`Adapters translate.`](docs/architecture/DATA_FLOW.md:437)
+  - **Impact**: same.
+
+- [`TypeOrmSeasonRepository.constructor()`](adapters/racing/persistence/typeorm/repositories/TypeOrmSeasonRepository.ts:10)
+  - **Why**: Default-constructs mapper via [`new SeasonOrmMapper()`](adapters/racing/persistence/typeorm/repositories/TypeOrmSeasonRepository.ts:12).
+  - **Rule violated**: [`Adapters translate.`](docs/architecture/DATA_FLOW.md:437)
+
+- Positive control (already aligned): [`TypeOrmLeagueScoringConfigRepository.constructor()`](adapters/racing/persistence/typeorm/repositories/TypeOrmLeagueScoringConfigRepository.ts:10)
+  - Requires mapper injection (no internal construction), and is enforced by [`TypeOrmLeagueScoringConfigRepository.test.ts`](adapters/racing/persistence/typeorm/repositories/TypeOrmLeagueScoringConfigRepository.test.ts:17).
+
+### 3) Persistence schema typing issues that currently force `unknown`/`any` translation — **Follow-up (but required by the canonical strict pattern)**
+
+These aren’t explicitly spelled out in the architecture docs, but they directly undermine “adapters translate only” by making translation ambiguous and unsafe. They also block strict `rehydrate()` mapping because you can’t validate/interpret persisted JSON precisely.
+
+- [`LeagueOrmEntity.settings`](adapters/racing/persistence/typeorm/entities/LeagueOrmEntity.ts:17)
+  - Current: `Record<string, unknown>`
+  - Problem: forces coercion and casts in [`LeagueOrmMapper.toOrmEntity()`](adapters/racing/persistence/typeorm/mappers/LeagueOrmMapper.ts:31) and [`LeagueOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/LeagueOrmMapper.ts:46).
+
+- [`SeasonOrmEntity.schedule`](adapters/racing/persistence/typeorm/entities/SeasonOrmEntity.ts:32), [`SeasonOrmEntity.scoringConfig`](adapters/racing/persistence/typeorm/entities/SeasonOrmEntity.ts:38), [`SeasonOrmEntity.dropPolicy`](adapters/racing/persistence/typeorm/entities/SeasonOrmEntity.ts:41), [`SeasonOrmEntity.stewardingConfig`](adapters/racing/persistence/typeorm/entities/SeasonOrmEntity.ts:44)
+  - Current: `Record<string, unknown> | null`
+  - Problem: propagates into pervasive `as any` in [`SeasonOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/SeasonOrmMapper.ts:26).
+
+- [`RaceOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/RaceOrmMapper.ts:23) and [`SeasonOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/SeasonOrmMapper.ts:26)
+  - Current: `as any` casts for status/sessionType/schedule/etc.
+  - Problem: translation is not explicit/verified; makes persisted schema errors show up as domain behavior or runtime surprises.
+
+### 4) Persistence boundary error mapping gaps — **Blocker**
+
+- [`LeagueOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/LeagueOrmMapper.ts:46), [`RaceOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/RaceOrmMapper.ts:23), [`SeasonOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/SeasonOrmMapper.ts:26)
+  - **Why**: because these call `create()` and use unsafe casts, the adapter does not reliably distinguish:
+    - invalid persisted schema (adapter concern) vs
+    - invalid incoming command/request (domain concern).
+  - **Rule violated (intent)**: separation of roles per [`Adapters translate.`](docs/architecture/DATA_FLOW.md:437) and persisted rehydration rule ([`rehydrate()`](docs/architecture/DOMAIN_OBJECTS.md:57)).
+  - **Impact**: domain errors (e.g. [`RacingDomainValidationError`](core/racing/domain/entities/League.ts:148)) can leak due to persistence drift, making debugging and recovery much harder.
+
+---
+
+## Canonical strict pattern for this repo (target state)
+
+This is the “golden path” all Racing TypeORM adapters should follow.
+
+### A) ORM entity shape rules (including JSON columns)
+
+- ORM entities are allowed in adapters per [`entities/ ORM-Entities (nicht Domain!)`](docs/architecture/FILE_STRUCTURE.md:47).
+- JSON columns must be **typed to a concrete serialized shape** (no `unknown`, no `Record<string, unknown>`).
+  - Example target types:
+    - `LeagueOrmEntity.settings: SerializedLeagueSettings`
+    - `SeasonOrmEntity.schedule: SerializedSeasonSchedule | null`
+    - `SeasonOrmEntity.scoringConfig: SerializedSeasonScoringConfig | null`
+- Serialized types must be:
+  - JSON-safe (no `Date`, `Map`, class instances)
+  - versionable (allow future `schemaVersion?: number`)
+  - strict enough to validate at runtime
+- Use `null` for absent optional columns (as already done in [`RaceOrmEntity.trackId`](adapters/racing/persistence/typeorm/entities/RaceOrmEntity.ts:17)).
+
+### B) Mapper rules (pure translation, no side effects)
+
+- Mappers are pure, deterministic translators:
+  - `domain -> orm` and `orm -> domain`
+  - no IO, no logging, no Date.now(), no random ids
+- **No `as any`** in mapping. If types don’t line up, fix the schema types or add a safe interpreter.
+- **No `create()` on load**. `orm -> domain` must call `rehydrate()` semantics for entities ([`rehydrate()` rule](docs/architecture/DOMAIN_OBJECTS.md:57)).
+- On `orm -> domain`:
+  - validate persisted schema and throw an **adapter-scoped persistence schema error**, not a domain validation error.
+  - treat invalid persisted schema as infrastructure failure (data corruption/migration mismatch).
+- On `domain -> orm`:
+  - serialize domain objects via explicit “serialize” helpers (no `as unknown as Record<...>`).
+- JSON mappers:
+  - must be pure
+  - must return serialized DTO-like shapes, not domain objects except as output of `fromJson`
+  - should avoid calling value-object constructors directly unless the VO explicitly treats constructor as a safe “rehydrate”; otherwise introduce `fromJson()`/`rehydrate()` for VOs.
+
+### C) Repository rules (IO + mapper only; composition root in Nest module)
+
+- Repositories implement core ports and do:
+  - DB IO (TypeORM queries)
+  - mapping via injected mappers
+- Repositories must not:
+  - construct mappers internally (`new` in constructor defaults)
+  - embed business logic/orchestration (that belongs to application services / use cases per [`Use Cases decide... Adapters translate.`](docs/architecture/DATA_FLOW.md:437))
+- Construction belongs in the Nest composition root:
+  - e.g. [`PostgresRacingPersistenceModule`](apps/api/src/persistence/postgres/PostgresRacingPersistenceModule.ts:57) should provide mapper instances and inject them into repositories.
+
+### D) Error handling rules (adapter-scoped errors vs domain errors)
+
+- Domain errors (e.g. [`RacingDomainValidationError`](core/racing/domain/entities/League.ts:148)) are for rejecting invalid **commands/new state transitions**.
+- Persistence adapters must throw adapter-scoped errors for:
+  - invalid persisted JSON schema
+  - impossible enum values/statuses stored in DB
+  - missing required persisted columns
+- Pattern baseline:
+  - follow [`InvalidLeagueScoringConfigChampionshipsSchemaError`](adapters/racing/persistence/typeorm/errors/InvalidLeagueScoringConfigChampionshipsSchemaError.ts:1) (adapter-owned, descriptive name, extends `Error`).
+- Repositories generally should not catch/translate DB errors unless you have a stable policy (e.g. unique violations) — keep this explicit and adapter-scoped if introduced.
+
+---
+
+## Controlled refactor plan (2–3 slices)
+
+Each slice is designed to be reviewable and to keep the system runnable.
+
+### Slice 1 — Mappers: `rehydrate()` + typed JSON schemas (DB-free unit tests)
+
+**Goal**
+- Make all `orm -> domain` mapping use rehydration semantics and strict, typed persisted schemas.
+- Remove `as any` from mapper paths by fixing schema types and adding validators.
+
+**Files to touch (exact)**
+- Mapper implementations:
+  - [`LeagueOrmMapper`](adapters/racing/persistence/typeorm/mappers/LeagueOrmMapper.ts:30)
+  - [`RaceOrmMapper`](adapters/racing/persistence/typeorm/mappers/RaceOrmMapper.ts:5)
+  - [`SeasonOrmMapper`](adapters/racing/persistence/typeorm/mappers/SeasonOrmMapper.ts:4)
+  - (keep as reference) [`LeagueScoringConfigOrmMapper`](adapters/racing/persistence/typeorm/mappers/LeagueScoringConfigOrmMapper.ts:42)
+  - JSON mappers as needed:
+    - [`PointsTableJsonMapper`](adapters/racing/persistence/typeorm/mappers/PointsTableJsonMapper.ts:7)
+    - [`ChampionshipConfigJsonMapper`](adapters/racing/persistence/typeorm/mappers/ChampionshipConfigJsonMapper.ts:17)
+- ORM entities (type JSON columns to serialized types):
+  - [`LeagueOrmEntity`](adapters/racing/persistence/typeorm/entities/LeagueOrmEntity.ts:4)
+  - [`SeasonOrmEntity`](adapters/racing/persistence/typeorm/entities/SeasonOrmEntity.ts:4)
+- Add adapter-scoped schema error types (new files under the existing folder):
+  - create new errors in [`adapters/racing/persistence/typeorm/errors/`](adapters/racing/persistence/typeorm/errors/InvalidLeagueScoringConfigChampionshipsSchemaError.ts:1)
+- Core changes required to satisfy rehydration rule (yes, this reaches into core because the adapter cannot comply otherwise):
+  - add `static rehydrate(...)` to:
+    - [`League`](core/racing/domain/entities/League.ts:93)
+    - [`Race`](core/racing/domain/entities/Race.ts:18)
+    - [`Season`](core/racing/domain/entities/season/Season.ts:14)
+
+**Acceptance tests (DB-free)**
+- Add mapper unit tests in the same pattern as [`LeagueScoringConfigOrmMapper.test.ts`](adapters/racing/persistence/typeorm/mappers/LeagueScoringConfigOrmMapper.test.ts:10):
+  - new: `LeagueOrmMapper.test.ts` verifies [`LeagueOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/LeagueOrmMapper.ts:46) calls `rehydrate()` and does not call [`League.create()`](core/racing/domain/entities/League.ts:132).
+  - new: `RaceOrmMapper.test.ts` verifies [`RaceOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/RaceOrmMapper.ts:23) uses `rehydrate()` and never calls [`Race.create()`](core/racing/domain/entities/Race.ts:81).
+  - new: `SeasonOrmMapper.test.ts` verifies [`SeasonOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/SeasonOrmMapper.ts:26) uses `rehydrate()` and never calls [`Season.create()`](core/racing/domain/entities/season/Season.ts:70).
+- Add schema validation tests:
+  - invalid JSON column shapes throw adapter error types (similar to [`InvalidLeagueScoringConfigChampionshipsSchemaError`](adapters/racing/persistence/typeorm/errors/InvalidLeagueScoringConfigChampionshipsSchemaError.ts:1)), not domain validation errors.
+
+**Definition of done**
+- No `create()` calls in any `toDomain()` for persisted entities.
+- No `as any` in mapper implementations.
+- JSON columns are typed to explicit `Serialized*` types, and validated on load.
+
+---
+
+### Slice 2 — Repository wiring cleanup (DI, no `new` inside repos)
+
+**Goal**
+- Repositories remain IO + mapper only.
+- Mapper graphs are constructed in the Nest module composition root.
+
+**Files to touch (exact)**
+- Repositories:
+  - [`TypeOrmLeagueRepository`](adapters/racing/persistence/typeorm/repositories/TypeOrmLeagueRepository.ts:9)
+  - [`TypeOrmRaceRepository`](adapters/racing/persistence/typeorm/repositories/TypeOrmRaceRepository.ts:9)
+  - [`TypeOrmSeasonRepository`](adapters/racing/persistence/typeorm/repositories/TypeOrmSeasonRepository.ts:9)
+  - (already OK, keep consistent) [`TypeOrmLeagueScoringConfigRepository`](adapters/racing/persistence/typeorm/repositories/TypeOrmLeagueScoringConfigRepository.ts:9)
+- Composition root wiring:
+  - [`PostgresRacingPersistenceModule`](apps/api/src/persistence/postgres/PostgresRacingPersistenceModule.ts:57)
+- Integration tests that new repos directly (update constructor signatures):
+  - [`PostgresLeagueScheduleRepositorySlice.int.test.ts`](apps/api/src/persistence/postgres/typeorm/PostgresLeagueScheduleRepositorySlice.int.test.ts:55)
+- Mapper tests that assume default constructors (update as needed):
+  - [`RacingOrmMappers.test.ts`](apps/api/src/persistence/postgres/typeorm/RacingOrmMappers.test.ts:20)
+
+**Acceptance tests**
+- Add repository constructor tests mirroring the existing pattern in [`TypeOrmLeagueScoringConfigRepository.test.ts`](adapters/racing/persistence/typeorm/repositories/TypeOrmLeagueScoringConfigRepository.test.ts:17):
+  - new: `TypeOrmLeagueRepository.test.ts` asserts no internal `new LeagueOrmMapper()`.
+  - new: `TypeOrmRaceRepository.test.ts` asserts no internal `new RaceOrmMapper()`.
+  - new: `TypeOrmSeasonRepository.test.ts` asserts no internal `new SeasonOrmMapper()`.
+- `tsc` should enforce injection by making mapper a required constructor param (strongest guard).
+
+**Definition of done**
+- No repository has a default `new Mapper()` in constructor params.
+- Nest module provides mapper instances and injects them into repositories.
+
+---
+
+### Slice 3 (optional) — Postgres integration tests + minimal vertical verification
+
+**Goal**
+- Verify the new strict schemas + rehydrate semantics survive real persistence roundtrips.
+
+**Files to touch (exact)**
+- Existing integration test:
+  - [`PostgresLeagueScheduleRepositorySlice.int.test.ts`](apps/api/src/persistence/postgres/typeorm/PostgresLeagueScheduleRepositorySlice.int.test.ts:31)
+- Potentially add one focused mapper+repo roundtrip test per aggregate if gaps remain:
+  - extend [`PostgresLeagueScheduleRepositorySlice.int.test.ts`](apps/api/src/persistence/postgres/typeorm/PostgresLeagueScheduleRepositorySlice.int.test.ts:55) rather than adding many files.
+
+**Acceptance tests**
+- With `DATABASE_URL` set, integration suite passes and persists/reads:
+  - League with settings JSON
+  - Season with nullable JSON configs
+  - Race with status/sessionType mapping
+  - LeagueScoringConfig with championships JSON (already covered)
+
+---
+
+## Notes on current wiring (for context)
+
+- Nest composition root is already the correct place for construction:
+  - [`PostgresRacingPersistenceModule`](apps/api/src/persistence/postgres/PostgresRacingPersistenceModule.ts:57)
+- But it currently relies on repository default constructors for some mappers:
+  - e.g. provides [`TypeOrmLeagueRepository`](adapters/racing/persistence/typeorm/repositories/TypeOrmLeagueRepository.ts:9) via `new TypeOrmLeagueRepository(dataSource)` in [`PostgresRacingPersistenceModule`](apps/api/src/persistence/postgres/PostgresRacingPersistenceModule.ts:66)
+- League scoring config is already composed explicitly (good reference):
+  - constructs `PointsTableJsonMapper -> ChampionshipConfigJsonMapper -> LeagueScoringConfigOrmMapper` in [`PostgresRacingPersistenceModule`](apps/api/src/persistence/postgres/PostgresRacingPersistenceModule.ts:126)
+
+---
+
+## Top blockers (short list)
+
+- Persisted entity mapping calls `create()` instead of `rehydrate()`:
+  - [`LeagueOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/LeagueOrmMapper.ts:46)
+  - [`RaceOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/RaceOrmMapper.ts:23)
+  - [`SeasonOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/SeasonOrmMapper.ts:26)
+- Repositories build mappers internally (construction not confined to composition root):
+  - [`TypeOrmLeagueRepository.constructor()`](adapters/racing/persistence/typeorm/repositories/TypeOrmLeagueRepository.ts:10)
+  - [`TypeOrmRaceRepository.constructor()`](adapters/racing/persistence/typeorm/repositories/TypeOrmRaceRepository.ts:10)
+  - [`TypeOrmSeasonRepository.constructor()`](adapters/racing/persistence/typeorm/repositories/TypeOrmSeasonRepository.ts:10)
+- Untyped JSON columns and `as any` casts prevent strict translation and reliable schema error handling:
+  - [`LeagueOrmEntity.settings`](adapters/racing/persistence/typeorm/entities/LeagueOrmEntity.ts:17)
+  - [`SeasonOrmEntity.schedule`](adapters/racing/persistence/typeorm/entities/SeasonOrmEntity.ts:32)
+  - [`RaceOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/RaceOrmMapper.ts:23)
+  - [`SeasonOrmMapper.toDomain()`](adapters/racing/persistence/typeorm/mappers/SeasonOrmMapper.ts:26)
