+# Testing concept: fully testing [`adapters/`](adapters/:1)
+
+This is a Clean Architecture-aligned testing concept for completely testing the code under [`adapters/`](adapters/:1), using:
+
+- [`docs/TESTING_LAYERS.md`](docs/TESTING_LAYERS.md:1) (where test types belong)
+- [`docs/architecture/shared/ADAPTERS.md`](docs/architecture/shared/ADAPTERS.md:1) (what adapters are)
+- [`docs/architecture/shared/REPOSITORY_STRUCTURE.md`](docs/architecture/shared/REPOSITORY_STRUCTURE.md:1) (where things live)
+- [`docs/architecture/shared/DATA_FLOW.md`](docs/architecture/shared/DATA_FLOW.md:1) (dependency rule)
+- [`docs/TESTS.md`](docs/TESTS.md:1) (current repo testing practices)
+
+---
+
+## 1) Goal + constraints
+
+### 1.1 Goal
+Make [`adapters/`](adapters/:1) **safe to change** by covering:
+
+1. Correct port behavior (adapters implement Core ports correctly)
+2. Correct mapping across boundaries (domain ⇄ persistence, domain ⇄ external system)
+3. Correct error shaping at boundaries (adapter-scoped schema errors)
+4. Correct composition (small clusters like composite resolvers)
+5. Correct wiring assumptions (DI boundaries: repositories don’t construct their own mappers)
+
+### 1.2 Constraints / non-negotiables
+
+- Dependencies point inward: delivery apps → adapters → core per [`docs/architecture/shared/DATA_FLOW.md`](docs/architecture/shared/DATA_FLOW.md:13)
+- Adapters are reusable infrastructure implementations (no delivery concerns) per [`docs/architecture/shared/REPOSITORY_STRUCTURE.md`](docs/architecture/shared/REPOSITORY_STRUCTURE.md:25)
+- Tests live as close as possible to the code they verify per [`docs/TESTING_LAYERS.md`](docs/TESTING_LAYERS.md:6)
+
+---
+
+## 2) Test taxonomy for adapters (mapped to repo locations)
+
+This section translates [`docs/TESTING_LAYERS.md`](docs/TESTING_LAYERS.md:1) into concrete rules for adapter code.
+
+### 2.1 Local tests (live inside [`adapters/`](adapters/:1))
+
+These are the default for adapter correctness.
+
+#### A) Unit tests (file-adjacent)
+**Use for:**
+
+- schema guards (validate persisted/remote shapes)
+- error types (message formatting, details)
+- pure mappers (domain ⇄ orm/DTO)
+- in-memory repositories and deterministic services
+
+**Location:** next to implementation, e.g. [`adapters/logging/ConsoleLogger.test.ts`](adapters/logging/ConsoleLogger.test.ts:1)
+
+**Style:** behavior-focused with BDD structure from [`docs/TESTS.md`](docs/TESTS.md:23). Use simple `Given/When/Then` comments; do not assert internal calls unless that’s the observable contract.
+
+Reference anchor: [`typescript.describe()`](adapters/logging/ConsoleLogger.test.ts:4)
+
+#### B) Sociable unit tests (small collaborating cluster)
+**Use for:**
+
+- a repository using an injected mapper (repository + mapper + schema guard)
+- composite adapters (delegation and resolution order)
+
+**Location:** still adjacent to the “root” of the cluster, not necessarily to each file.
+
+Reference anchor: [`adapters/media/MediaResolverAdapter.test.ts`](adapters/media/MediaResolverAdapter.test.ts:1)
+
+#### C) Component / module tests (module invariants without infrastructure)
+**Use for:**
+
+- “module-level” adapter compositions that should behave consistently as a unit (e.g. a group of in-memory repos that are expected to work together)
+
+**Location:** adjacent to the module root.
+
+Reference anchor: [`adapters/racing/persistence/inmemory/InMemoryScoringRepositories.test.ts`](adapters/racing/persistence/inmemory/InMemoryScoringRepositories.test.ts:1)
+
+### 2.2 Global tests (live outside adapters)
+
+#### D) Contract tests (boundary tests)
+Contract tests belong at system boundaries per [`docs/TESTING_LAYERS.md`](docs/TESTING_LAYERS.md:88).
+
+For this repo there are two contract categories:
+
+1. **External system contracts** (API ↔ website) already documented in [`docs/CONTRACT_TESTING.md`](docs/CONTRACT_TESTING.md:1)
+2. **Internal port contracts** (core port interface ↔ adapter implementation)
+
+Internal port contracts are still valuable, but they are not “between systems”. Treat them as **shared executable specifications** for a port.
+
+**Proposed location:** [`tests/contracts/`](tests/:1)
+
+Principle: the contract suite imports the port interface from core and runs the same assertions against multiple adapter implementations (in-memory and TypeORM-DB-free where possible).
+
+#### E) Integration / E2E (system-level)
+Per [`docs/TESTS.md`](docs/TESTS.md:106):
+
+- Integration tests live in [`tests/integration/`](tests/:1) and use in-memory adapters.
+- E2E tests live in [`tests/e2e/`](tests/:1) and can use TypeORM/Postgres.
+
+Adapter code should *enable* these tests, but adapter *unit correctness* should not depend on these tests.
+
+---
+
+## 3) Canonical adapter test recipes (what to test, not how)
+
+These are reusable patterns to standardize how we test adapters.
+
+### 3.1 In-memory repositories (pure adapter behavior)
+
+**Minimum spec for an in-memory repository implementation:**
+
+- persists and retrieves the aggregate/value (happy path)
+- supports negative paths (not found returns null / empty)
+- enforces invariants that the real implementation must also enforce (uniqueness, idempotency)
+- does not leak references if immutability is expected (optional; depends on domain semantics)
+
+Examples:
+
+- [`adapters/identity/persistence/inmemory/InMemoryUserRepository.test.ts`](adapters/identity/persistence/inmemory/InMemoryUserRepository.test.ts:1)
+- [`adapters/racing/persistence/inmemory/InMemorySessionRepository.test.ts`](adapters/racing/persistence/inmemory/InMemorySessionRepository.test.ts:1)
+
+### 3.2 TypeORM mappers (mapping + validation)
+
+**Minimum spec for a mapper:**
+
+- domain → orm mapping produces a persistable shape
+- orm → domain mapping reconstitutes without calling “create” semantics (i.e., preserves persisted identity)
+- invalid persisted shape throws adapter-scoped schema error type
+
+Examples:
+
+- [`adapters/media/persistence/typeorm/mappers/MediaOrmMapper.test.ts`](adapters/media/persistence/typeorm/mappers/MediaOrmMapper.test.ts:1)
+- [`adapters/racing/persistence/typeorm/mappers/DriverOrmMapper.test.ts`](adapters/racing/persistence/typeorm/mappers/DriverOrmMapper.test.ts:1)
+
+### 3.3 TypeORM repositories (DB-free correctness + DI boundaries)
+
+**We split repository tests into 2 categories:**
+
+1. **DB-free repository behavior tests**: verify mapping is applied and correct ORM repository methods are called with expected shapes (using a stubbed TypeORM repository).
+2. **DI boundary tests**: verify no internal instantiation of mappers and that constructor requires injected dependencies.
+
+Examples:
+
+- [`adapters/media/persistence/typeorm/repositories/TypeOrmMediaRepository.test.ts`](adapters/media/persistence/typeorm/repositories/TypeOrmMediaRepository.test.ts:1)
+- [`adapters/payments/persistence/typeorm/repositories/TypeOrmPaymentRepository.test.ts`](adapters/payments/persistence/typeorm/repositories/TypeOrmPaymentRepository.test.ts:1)
+
+### 3.4 Schema guards + schema errors (adapter boundary hardening)
+
+**Minimum spec:**
+
+- guard accepts valid shapes
+- guard rejects invalid shapes with deterministic error messages
+- schema error contains enough details to debug (entity, field, reason)
+
+Examples:
+
+- [`adapters/admin/persistence/typeorm/schema/TypeOrmAdminSchemaGuards.test.ts`](adapters/admin/persistence/typeorm/schema/TypeOrmAdminSchemaGuards.test.ts:1)
+- [`adapters/admin/persistence/typeorm/errors/TypeOrmAdminSchemaError.test.ts`](adapters/admin/persistence/typeorm/errors/TypeOrmAdminSchemaError.test.ts:1)
+
+### 3.5 Gateways (external side effects)
+
+**Minimum spec:**
+
+- correct request construction (mapping domain intent → external API payload)
+- error handling and retries (if present)
+- logging behavior (only observable outputs)
+
+These tests should stub the external client; no real network.
+
+---
+
+## 4) Gap matrix (folder-level)
+
+Legend:
+
+- ✅ = present (at least one meaningful test exists)
+- ⚠️ = partially covered
+- ❌ = missing
+
+> Important: this matrix is based on the current directory contents under [`adapters/`](adapters/:1). It’s folder-level, not per-class.
+
+| Adapter folder | What exists | Local tests status | Missing tests (minimum) |
+|---|---|---:|---|
+| [`adapters/achievement/`](adapters/achievement/:1) | TypeORM entities/mappers/repository/schema guard | ❌ | Mapper tests, schema guard tests, repo DI boundary tests, schema error tests |
+| [`adapters/activity/`](adapters/activity/:1) | In-memory repository | ❌ | In-memory repo behavior test suite |
+| [`adapters/admin/`](adapters/admin/:1) | In-memory repo + TypeORM layer | ✅ | Consider adding DB-free repo tests consistency patterns for TypeORM (if not already), ensure schema guard coverage is complete |
+| [`adapters/analytics/`](adapters/analytics/:1) | In-memory repos + TypeORM layer | ⚠️ | Tests for TypeORM repos without tests, tests for non-tested mappers (`AnalyticsSnapshotOrmMapper`, `EngagementEventOrmMapper`), schema guard tests, schema error tests |
+| [`adapters/automation/`](adapters/automation/:1) | Config objects | ❌ | Unit tests for config parsing/merging defaults (if behavior exists); otherwise explicitly accept no tests |
+| [`adapters/bootstrap/`](adapters/bootstrap/:1) | Seeders + many config modules + factories | ⚠️ | Add unit tests for critical deterministic configs/factories not yet covered; establish module tests for seeding workflows (DB-free) |
+| [`adapters/drivers/`](adapters/drivers/:1) | In-memory repository | ❌ | In-memory repo behavior tests |
+| [`adapters/events/`](adapters/events/:1) | In-memory event publishers | ❌ | Behavior tests: publishes expected events to subscribers/collectors; ensure “no-op” safety |
+| [`adapters/health/`](adapters/health/:1) | In-memory health check adapter | ❌ | Behavior tests: healthy/unhealthy reporting, edge cases |
+| [`adapters/http/`](adapters/http/:1) | Request context module | ❌ | Unit tests for any parsing/propagation logic; otherwise explicitly accept no tests |
+| [`adapters/identity/`](adapters/identity/:1) | In-memory repos + TypeORM repos/mappers + services + session adapter | ⚠️ | Add tests for in-memory files without tests (company/external game rating), tests for TypeORM repos without tests, schema guards tests, cookie session adapter tests |
+| [`adapters/leaderboards/`](adapters/leaderboards/:1) | In-memory repo + event publisher | ❌ | Repo tests + publisher tests |
+| [`adapters/leagues/`](adapters/leagues/:1) | In-memory repo + event publisher | ❌ | Repo tests + publisher tests |
+| [`adapters/logging/`](adapters/logging/:1) | Console logger + error reporter | ⚠️ | Add tests for error reporter behavior; keep logger tests |
+| [`adapters/media/`](adapters/media/:1) | Resolvers + in-memory repos + TypeORM layer + ports | ⚠️ | Add tests for in-memory repos without tests, file-system storage adapter tests, gateway/event publisher tests if behavior exists |
+| [`adapters/notifications/`](adapters/notifications/:1) | Gateways + persistence + ports | ⚠️ | Add gateway tests, registry tests, port adapter tests; schema guard tests for TypeORM |
+| [`adapters/payments/`](adapters/payments/:1) | In-memory repos + TypeORM layer | ⚠️ | Add tests for non-tested mappers, non-tested repos, schema guard tests |
+| [`adapters/persistence/`](adapters/persistence/:1) | In-memory achievement repo + migration script | ⚠️ | Decide whether migrations are tested (usually via E2E/integration). If treated as code, add smoke test for migration shape |
+| [`adapters/races/`](adapters/races/:1) | In-memory repository | ❌ | In-memory repo behavior tests |
+| [`adapters/racing/`](adapters/racing/:1) | Large in-memory + TypeORM layer; many tests | ✅ | Add tests for remaining untested files (notably some in-memory repos and TypeORM repos/mappers without tests) |
+| [`adapters/rating/`](adapters/rating/:1) | In-memory repository | ❌ | In-memory repo behavior tests |
+| [`adapters/social/`](adapters/social/:1) | In-memory + TypeORM; some tests | ⚠️ | Add tests for TypeORM social graph repository, schema guards, and any missing in-memory invariants |
+| [`adapters/eslint-rules/`](adapters/eslint-rules/:1) | ESLint rules | ⚠️ | Optional: rule tests (if the project values rule stability); otherwise accept manual verification |
+
+---
+
+## 5) Priority order (risk-first)
+
+If “completely tested” is the goal, this is the order I’d implement missing tests.
+
+1. Persistence adapters that can corrupt or misread data (TypeORM mappers + schema guards) under [`adapters/racing/persistence/typeorm/`](adapters/racing/persistence/typeorm/:1), [`adapters/identity/persistence/typeorm/`](adapters/identity/persistence/typeorm/:1), [`adapters/payments/persistence/typeorm/`](adapters/payments/persistence/typeorm/:1)
+2. Un-tested persistence folders with real production impact: [`adapters/achievement/`](adapters/achievement/:1), [`adapters/analytics/`](adapters/analytics/:1)
+3. External side-effect gateways: [`adapters/notifications/gateways/`](adapters/notifications/gateways/:1)
+4. Small but foundational shared utilities (request context, health, event publishers): [`adapters/http/`](adapters/http/:1), [`adapters/health/`](adapters/health/:1), [`adapters/events/`](adapters/events/:1)
+5. Remaining in-memory repos to keep integration tests trustworthy: [`adapters/activity/`](adapters/activity/:1), [`adapters/drivers/`](adapters/drivers/:1), [`adapters/races/`](adapters/races/:1), [`adapters/rating/`](adapters/rating/:1), [`adapters/leaderboards/`](adapters/leaderboards/:1), [`adapters/leagues/`](adapters/leagues/:1)
+
+---
+
+## 6) Definition of done (what “completely tested adapters” means)
+
+For each adapter module under [`adapters/`](adapters/:1):
+
+1. Every in-memory repository has a behavior test (happy path + at least one negative path).
+2. Every TypeORM mapper has a mapping test and an invalid-shape test.
+3. Every TypeORM repository has at least a DB-free test proving:
+   - dependencies are injected (no internal `new Mapper()` patterns)
+   - mapping is applied on save/load
+4. Every schema guard and schema error class is tested.
+5. Every external gateway has a stubbed-client unit test verifying payload mapping and error shaping.
+6. At least one module-level test exists for any composite adapter (delegation order + null-handling).
+7. Anything that is intentionally “not worth unit-testing” is explicitly declared and justified in the gap matrix (to avoid silent omissions).
+
+---
+
+## 7) Optional: internal port-contract test harness (shared executable specs)
+
+If we want the same behavioral contract applied across multiple adapter implementations, add a tiny harness under [`tests/contracts/`](tests/:1):
+
+- `tests/contracts/<feature>/<PortName>.contract.ts`
+  - exports a function that takes a factory creating an implementation
+- Each adapter test imports that contract and runs it
+
+This keeps contracts central **without** moving tests away from the code (the adapter still owns the “run this contract for my implementation” test file).
+
+---
+
+## 8) Mode switch intent
+
+After you approve this concept, the implementation phase is to add the missing tests adjacent to the adapter files and (optionally) introduce `tests/contracts/` without breaking dependency rules.

+# Testing gaps in `core` (unit tests only, no infra/adapters)
+
+## Scope / rules (agreed)
+
+* **In scope:** code under [`core/`](core:1) only.
+* **Unit tests only:** tests should validate business rules and orchestration using **ports mocked in-test** (e.g., `vi.fn()`), not real persistence, HTTP, frameworks, or adapters.
+* **Out of scope:** any test that relies on real IO, real repositories, or infrastructure code (including [`core/**/infrastructure/`](core/rating/infrastructure:1)).
+
+## How gaps were identified
+
+1. Inventory of application and domain units was built from file structure under [`core/`](core:1).
+2. Existing tests were located via `describe(` occurrences in `*.test.ts` and mapped to corresponding production units.
+3. Gaps were prioritized by:
+   * **Business criticality:** identity/security, payments/money flows.
+   * **Complex branching / invariants:** state machines, decision tables.
+   * **Time-dependent logic:** `Date.now()`, `new Date()`, time windows.
+   * **Error handling paths:** repository errors, partial failures.
+
+---
+
+## Highest-priority testing gaps (P0)
+
+### 1) `rating` module has **no unit tests**
+
+Why high risk: scoring/rating is a cross-cutting “truth source”, and current implementations contain test-driven hacks and inconsistent error handling.
+
+Targets:
+* [`core/rating/application/use-cases/CalculateRatingUseCase.ts`](core/rating/application/use-cases/CalculateRatingUseCase.ts:1)
+* [`core/rating/application/use-cases/CalculateTeamContributionUseCase.ts`](core/rating/application/use-cases/CalculateTeamContributionUseCase.ts:1)
+* [`core/rating/application/use-cases/GetRatingLeaderboardUseCase.ts`](core/rating/application/use-cases/GetRatingLeaderboardUseCase.ts:1)
+* [`core/rating/application/use-cases/SaveRatingUseCase.ts`](core/rating/application/use-cases/SaveRatingUseCase.ts:1)
+* [`core/rating/domain/Rating.ts`](core/rating/domain/Rating.ts:1)
+
+Proposed unit tests (Given/When/Then):
+1. **CalculateRatingUseCase: driver missing**
+   * Given `driverRepository.findById` returns `null`
+   * When executing with `{ driverId, raceId }`
+   * Then returns `Result.err` with message `Driver not found` and does not call `ratingRepository.save`.
+2. **CalculateRatingUseCase: race missing**
+   * Given driver exists, `raceRepository.findById` returns `null`
+   * When execute
+   * Then returns `Result.err` with message `Race not found`.
+3. **CalculateRatingUseCase: no results**
+   * Given driver & race exist, `resultRepository.findByRaceId` returns `[]`
+   * When execute
+   * Then returns `Result.err` with message `No results found for race`.
+4. **CalculateRatingUseCase: driver not present in results**
+   * Given results array without matching `driverId`
+   * When execute
+   * Then returns `Result.err` with message `Driver not found in race results`.
+5. **CalculateRatingUseCase: publishes event after save**
+   * Given all repositories return happy-path objects
+   * When execute
+   * Then `ratingRepository.save` is called once before `eventPublisher.publish`.
+6. **CalculateRatingUseCase: component boundaries**
+   * Given a result with `incidents = 0`
+   * When execute
+   * Then `components.cleanDriving === 100`.
+   * Given `incidents >= 5`
+   * Then `components.cleanDriving === 20`.
+7. **CalculateRatingUseCase: time-dependent output**
+   * Given frozen time (use `vi.setSystemTime`)
+   * When execute
+   * Then emitted rating has deterministic `timestamp`.
+8. **CalculateTeamContributionUseCase: creates rating when missing**
+   * Given `ratingRepository.findByDriverAndRace` returns `null`
+   * When execute
+   * Then `ratingRepository.save` is called with a rating whose `components.teamContribution` matches calculation.
+9. **CalculateTeamContributionUseCase: updates existing rating**
+   * Given existing rating with components set
+   * When execute
+   * Then only `components.teamContribution` is changed and other fields preserved.
+10. **GetRatingLeaderboardUseCase: pagination + sorting**
+   * Given multiple drivers and multiple ratings per driver
+   * When execute with `{ limit, offset }`
+   * Then returns latest per driver, sorted desc, sliced by pagination.
+11. **SaveRatingUseCase: repository error wraps correctly**
+   * Given `ratingRepository.save` throws
+   * When execute
+   * Then throws `Failed to save rating:` prefixed error.
+
+Ports to mock: `driverRepository`, `raceRepository`, `resultRepository`, `ratingRepository`, `eventPublisher`.
+
+---
+
+### 2) `dashboard` orchestration has no unit tests
+
+Target:
+* [`core/dashboard/application/use-cases/GetDashboardUseCase.ts`](core/dashboard/application/use-cases/GetDashboardUseCase.ts:1)
+
+Why high risk: timeouts, parallelization, filtering/sorting, and “log but don’t fail” event publishing.
+
+Proposed unit tests (Given/When/Then):
+1. **Validation of driverId**
+   * Given `driverId` is `''` or whitespace
+   * When execute
+   * Then throws [`ValidationError`](core/shared/errors/ValidationError.ts:1) (or the module’s equivalent) and does not hit repositories.
+2. **Driver not found**
+   * Given `driverRepository.findDriverById` returns `null`
+   * When execute
+   * Then throws [`DriverNotFoundError`](core/dashboard/domain/errors/DriverNotFoundError.ts:1).
+3. **Filters invalid races**
+   * Given `getUpcomingRaces` returns races missing `trackName` or with past `scheduledDate`
+   * When execute
+   * Then `upcomingRaces` in DTO excludes them.
+4. **Limits upcoming races to 3 and sorts by date ascending**
+   * Given 5 valid upcoming races out of order
+   * When execute
+   * Then DTO contains only 3 earliest.
+5. **Activity is sorted newest-first**
+   * Given activities with different timestamps
+   * When execute
+   * Then DTO is sorted desc by timestamp.
+6. **Repository failures are logged and rethrown**
+   * Given one of the repositories rejects
+   * When execute
+   * Then logger.error called and error is rethrown.
+7. **Event publishing failure is swallowed**
+   * Given `eventPublisher.publishDashboardAccessed` throws
+   * When execute
+   * Then use case still returns DTO and logger.error was called.
+8. **Timeout behavior** (if retained)
+   * Given `raceRepository.getUpcomingRaces` never resolves
+   * When using fake timers and advancing by TIMEOUT
+   * Then `upcomingRaces` becomes `[]` and use case completes.
+
+Ports to mock: all repositories, publisher, and [`Logger`](core/shared/domain/Logger.ts:1).
+
+---
+
+### 3) `leagues` module has multiple untested use-cases (time-dependent logic)
+
+Targets likely missing tests:
+* [`core/leagues/application/use-cases/JoinLeagueUseCase.ts`](core/leagues/application/use-cases/JoinLeagueUseCase.ts:1)
+* [`core/leagues/application/use-cases/LeaveLeagueUseCase.ts`](core/leagues/application/use-cases/LeaveLeagueUseCase.ts:1)
+* [`core/leagues/application/use-cases/ApproveMembershipRequestUseCase.ts`](core/leagues/application/use-cases/ApproveMembershipRequestUseCase.ts:1)
+* plus others without `*.test.ts` siblings in [`core/leagues/application/use-cases/`](core/leagues/application/use-cases:1)
+
+Proposed unit tests (Given/When/Then):
+1. **JoinLeagueUseCase: league missing**
+   * Given `leagueRepository.findById` returns `null`
+   * When execute
+   * Then throws `League not found`.
+2. **JoinLeagueUseCase: driver missing**
+   * Given league exists, `driverRepository.findDriverById` returns `null`
+   * Then throws `Driver not found`.
+3. **JoinLeagueUseCase: approvalRequired path uses pending requests**
+   * Given `league.approvalRequired === true`
+   * When execute
+   * Then `leagueRepository.addPendingRequests` called with a request containing frozen `Date.now()` and `new Date()`.
+4. **JoinLeagueUseCase: no-approval path adds member**
+   * Given `approvalRequired === false`
+   * Then `leagueRepository.addLeagueMembers` called with role `member`.
+5. **ApproveMembershipRequestUseCase: request not found**
+   * Given pending requests list without `requestId`
+   * Then throws `Request not found`.
+6. **ApproveMembershipRequestUseCase: happy path adds member then removes request**
+   * Given request exists
+   * Then `addLeagueMembers` called before `removePendingRequest`.
+7. **LeaveLeagueUseCase: delegates to repository**
+   * Given repository mock
+   * Then `removeLeagueMember` is called once with inputs.
+
+Note: these use cases currently ignore injected `eventPublisher` in several places; tests should either (a) enforce event publication (drive implementation), or (b) remove the unused port.
+
+---
+
+## Medium-priority gaps (P1)
+
+### 4) “Contract tests” that don’t test behavior (replace or move)
+
+These tests validate TypeScript shapes and mocked method existence, but do not protect business behavior:
+* [`core/ports/media/MediaResolverPort.test.ts`](core/ports/media/MediaResolverPort.test.ts:1)
+* [`core/ports/media/MediaResolverPort.comprehensive.test.ts`](core/ports/media/MediaResolverPort.comprehensive.test.ts:1)
+* [`core/notifications/domain/repositories/NotificationRepository.test.ts`](core/notifications/domain/repositories/NotificationRepository.test.ts:1)
+* [`core/notifications/application/ports/NotificationService.test.ts`](core/notifications/application/ports/NotificationService.test.ts:1)
+
+Recommended action:
+* Either delete these (if they add noise), or replace with **behavior tests of the code that consumes the port**.
+* If you want explicit “contract tests”, keep them in a dedicated layer and ensure they test the *adapter implementation* (but that would violate the current constraint, so keep them out of this scope).
+
+### 5) Racing and Notifications include “imports-only” tests
+
+Several tests are effectively “module loads” checks (no business assertions). Example patterns show up in:
+* [`core/notifications/domain/entities/Notification.test.ts`](core/notifications/domain/entities/Notification.test.ts:1)
+* [`core/notifications/domain/entities/NotificationPreference.test.ts`](core/notifications/domain/entities/NotificationPreference.test.ts:1)
+* many files under [`core/racing/domain/entities/`](core/racing/domain/entities:1)
+
+Replace with invariant-focused tests:
+* Given invalid props (empty IDs, invalid status transitions)
+* When creating or transitioning state
+* Then throws domain error (or returns `Result.err`) with specific code/kind.
+
+### 6) Racing use-cases with no tests (spot list)
+
+From a quick scan of [`core/racing/application/use-cases/`](core/racing/application/use-cases:1), some `.ts` appear without matching `.test.ts` siblings:
+* [`core/racing/application/use-cases/GetAllLeaguesWithCapacityUseCase.ts`](core/racing/application/use-cases/GetAllLeaguesWithCapacityUseCase.ts:1)
+* [`core/racing/application/use-cases/GetRaceProtestsUseCase.ts`](core/racing/application/use-cases/GetRaceProtestsUseCase.ts:1)
+* [`core/racing/application/use-cases/GetRaceRegistrationsUseCase.ts`](core/racing/application/use-cases/GetRaceRegistrationsUseCase.ts:1) (appears tested, confirm)
+* [`core/racing/application/use-cases/GetSponsorsUseCase.ts`](core/racing/application/use-cases/GetSponsorsUseCase.ts:1) (no test file listed)
+* [`core/racing/application/use-cases/GetLeagueAdminUseCase.ts`](core/racing/application/use-cases/GetLeagueAdminUseCase.ts:1)
+* [`core/racing/application/use-cases/UnpublishLeagueSeasonScheduleUseCase.ts`](core/racing/application/use-cases/UnpublishLeagueSeasonScheduleUseCase.ts:1)
+* [`core/racing/application/use-cases/SubmitProtestDefenseUseCase.test.ts`](core/racing/application/use-cases/SubmitProtestDefenseUseCase.test.ts:1) exists, confirm content quality
+
+Suggested scenarios depend on each use case’s branching, but the common minimum is:
+* repository error → `Result.err` with code
+* happy path → updates correct aggregates + publishes domain event if applicable
+* permission/invariant violations → domain error codes
+
+---
+
+## Lower-priority gaps (P2)
+
+### 7) Coverage consistency and determinism
+
+Patterns to standardize across modules:
+* Tests that touch time should freeze time (`vi.setSystemTime`) rather than relying on `Date.now()`.
+* Use cases should return `Result` consistently (some throw, some return `Result`). Testing should expose this inconsistency and drive convergence.
+
+---
+
+## Proposed execution plan (next step: implement tests)
+
+1. Add missing unit tests for `rating` use-cases and `rating/domain/Rating`.
+2. Add unit tests for `GetDashboardUseCase` focusing on filtering/sorting, timeout, and publish failure behavior.
+3. Add unit tests for `leagues` membership flow (`JoinLeagueUseCase`, `ApproveMembershipRequestUseCase`, `LeaveLeagueUseCase`).
+4. Replace “imports-only” tests with invariant tests in `notifications` entities, starting with the most used aggregates.
+5. Audit remaining racing use-cases without tests and add the top 5 based on branching and business impact.
