 GridPilot follows strict BDD (Behavior-Driven Development) with comprehensive test coverage.
 
 ### Local Verification Pipeline
-Run this sequence before pushing to ensure correctness:
+
-```bash
+GridPilot uses **lint-staged** to automatically validate only changed files on commit:
-npm run lint && npm run typecheck && npm run test:unit && npm run test:integration
+
-```
+- `eslint --fix` runs on changed JS/TS/TSX files
+- `vitest related --run` runs tests related to changed files
+- `prettier --write` formats JSON, MD, and YAML files
+
+This ensures fast commits without running the full test suite.
+
+### Pre-Push Hook
+
+A **pre-push hook** runs the full verification pipeline before pushing to remote:
+
+- `npm run lint` - Check for linting errors
+- `npm run typecheck` - Verify TypeScript types
+- `npm run test:unit` - Run unit tests
+- `npm run test:integration` - Run integration tests
+
+You can skip this with `git push --no-verify` if needed.
 
 ### Individual Commands

 # Run all tests

+# CI/CD & Dev Experience Optimization Plan
+
+## Current Situation
+
+- **Husky `pre-commit`**: Runs `npm test` (Vitest) on every commit. This likely runs the entire test suite, which is slow and frustrating for developers.
+- **Gitea Actions**: Currently only has `contract-testing.yml`.
+- **Missing**: No automated linting or type-checking in CI, no tiered testing strategy.
+
+## Proposed Strategy: The "Fast Feedback Loop"
+
+We will implement a tiered approach to balance speed and safety.
+
+### 1. Local Development (Husky + lint-staged)
+
+**Goal**: Prevent obvious errors from entering the repo without slowing down the dev.
+
+- **Trigger**: `pre-commit`
+- **Action**: Only run on **staged files**.
+- **Tasks**:
+  - `eslint --fix`
+  - `prettier --write`
+  - `vitest related` (only run tests related to changed files)
+
+### 2. Pull Request (Gitea Actions)
+
+**Goal**: Ensure the branch is stable and doesn't break the build or other modules.
+
+- **Trigger**: PR creation and updates.
+- **Tasks**:
+  - Full `lint`
+  - Full `typecheck` (crucial for monorepo integrity)
+  - Full `unit tests`
+  - `integration tests`
+  - `contract tests`
+
+### 3. Merge to Main / Release (Gitea Actions)
+
+**Goal**: Final verification before deployment.
+
+- **Trigger**: Push to `main` or `develop`.
+- **Tasks**:
+  - Everything from PR stage.
+  - `e2e tests` (Playwright) - these are the slowest and most expensive.
+
+---
+
+## Implementation Steps
+
+### Step 1: Install and Configure `lint-staged`
+
+We need to add `lint-staged` to [`package.json`](package.json) and update the Husky hook.
+
+### Step 2: Optimize Husky Hook
+
+Update [`.husky/pre-commit`](.husky/pre-commit) to run `npx lint-staged` instead of `npm test`.
+
+### Step 3: Create Comprehensive CI Workflow
+
+Create `.github/workflows/ci.yml` (Gitea Actions compatible) to handle the heavy lifting.
+
+---

+```json
+{
+  "*.{js,ts,tsx}": ["eslint --fix", "vitest related --run"],
+  "*.{json,md,yml}": ["prettier --write"]
+}
+```
+
+---
+
+## Questions for the User
+
+1. Do you want to include `typecheck` in the `pre-commit` hook? (Note: `tsc` doesn't support linting only changed files easily, so it usually checks the whole project, which might be slow).
+2. Should we run `integration tests` on every PR, or only on merge to `main`?
+3. Are there specific directories that should be excluded from this automated flow?

+# Test Coverage Analysis & Gap Report
+
+## 1. Executive Summary
+We have compared the existing E2E and Integration tests against the core concepts defined in [`docs/concept/`](docs/concept) and the testing principles in [`docs/TESTING_LAYERS.md`](docs/TESTING_LAYERS.md). 
+
+While the functional coverage is high, there are critical gaps in **Integration Testing** specifically regarding external boundaries (iRacing API) and specific infrastructure-heavy business logic (Rating Engine).
+
+## 2. Concept vs. Test Mapping
+
+| Concept Area | E2E Coverage | Integration Coverage | Status |
+|--------------|--------------|----------------------|--------|
+| **League Management** | [`leagues/`](tests/e2e/leagues) | [`leagues/`](tests/integration/leagues) | ✅ Covered |
+| **Season/Schedule** | [`leagues/league-schedule.spec.ts`](tests/e2e/leagues/league-schedule.spec.ts) | [`leagues/schedule/`](tests/integration/leagues/schedule) | ✅ Covered |
+| **Results Import** | [`races/race-results.spec.ts`](tests/e2e/races/race-results.spec.ts) | [`races/results/`](tests/integration/races/results) | ⚠️ Missing iRacing API Integration |
+| **Complaints/Penalties** | [`leagues/league-stewarding.spec.ts`](tests/e2e/leagues/league-stewarding.spec.ts) | [`races/stewarding/`](tests/integration/races/stewarding) | ✅ Covered |
+| **Team Competition** | [`teams/`](tests/e2e/teams) | [`teams/`](tests/integration/teams) | ✅ Covered |
+| **Driver Profile/Stats** | [`drivers/`](tests/e2e/drivers) | [`drivers/profile/`](tests/integration/drivers/profile) | ✅ Covered |
+| **Rating System** | None | None | ❌ Missing |
+| **Social/Messaging** | None | None | ❌ Missing |
+
+## 3. Identified Gaps in Integration Tests
+
+According to [`docs/TESTING_LAYERS.md`](docs/TESTING_LAYERS.md), integration tests should protect **environmental correctness** (DB, external APIs, Auth).
+
+### 🚨 Critical Gaps (Infrastructure/Boundaries)
+1. **iRacing API Integration**: 
+   - *Concept*: [`docs/concept/ADMINS.md`](docs/concept/ADMINS.md:83) (Automatic Results Import).
+   - *Gap*: We have tests for *displaying* results, but no integration tests verifying the actual handshake and parsing logic with the iRacing API boundary.
+2. **Rating Engine Persistence**:
+   - *Concept*: [`docs/concept/RATING.md`](docs/concept/RATING.md) (GridPilot Rating).
+   - *Gap*: The rating system involves complex calculations that must be persisted correctly. We lack integration tests for the `RatingService` interacting with the DB.
+3. **Auth/Identity Provider**:
+   - *Concept*: [`docs/concept/CONCEPT.md`](docs/concept/CONCEPT.md:172) (Safety, Security & Trust).
+   - *Gap*: No integration tests for the Auth boundary (e.g., JWT validation, session persistence).
+
+### 🛠 Functional Gaps (Business Logic Integration)
+1. **Social/Messaging**:
+   - *Concept*: [`docs/concept/SOCIAL.md`](docs/concept/SOCIAL.md) (Messaging, Notifications).
+   - *Gap*: No integration tests for message persistence or notification delivery (queues).
+2. **Constructors-Style Scoring**:
+   - *Concept*: [`docs/concept/RACING.md`](docs/concept/RACING.md:47) (Constructors-Style Points).
+   - *Gap*: While we have `StandingsCalculation.test.ts`, we need specific integration tests for complex multi-driver team scoring scenarios against the DB.
+
+## 4. Proposed Action Plan
+
+1. **Implement iRacing API Contract/Integration Tests**: Verify the parsing of iRacing result payloads.
+2. **Add Rating Persistence Tests**: Ensure `GridPilot Rating` updates correctly in the DB after race results are processed.
+3. **Add Social/Notification Integration**: Test the persistence of messages and the triggering of notifications.
+4. **Auth Integration**: Verify the system-level Auth flow as per the "Trust" requirement.
+

+*Uncle Bob's Note: Remember, the closer a test is to the code, the more of them you should have. But for the system to be robust, the boundaries must be ironclad.*

-# API Smoke Tests
-
-This directory contains true end-to-end API smoke tests that make direct HTTP requests to the running API server to validate endpoint functionality and detect issues like "presenter not presented" errors.
-
-## Overview
-
-The API smoke tests are designed to:
-
-1. **Test all public API endpoints** - Make requests to discover and validate endpoints
-2. **Detect presenter errors** - Identify use cases that return errors without calling `this.output.present()`
-3. **Validate response formats** - Ensure endpoints return proper data structures
-4. **Test error handling** - Verify graceful handling of invalid inputs
-5. **Generate detailed reports** - Create JSON and Markdown reports of findings
-
-## Files
-
-- `api-smoke.test.ts` - Main Playwright test file
-- `README.md` - This documentation
-
-## Usage
-
-### Local Testing
-
-Run the API smoke tests against a locally running API:
-
-```bash
-# Start the API server (in one terminal)
-npm run docker:dev:up
-
-# Run smoke tests (in another terminal)
-npm run test:api:smoke
-```
-
-### Docker Testing (Recommended)
-
-Run the tests in the full Docker e2e environment:
-
-```bash
-# Start the complete e2e environment
-npm run docker:e2e:up
-
-# Run smoke tests in Docker
-npm run test:api:smoke:docker
-
-# Or use the unified command
-npm run test:e2e:website  # This runs all e2e tests including API smoke
-```
-
-### CI/CD Integration
-
-Add to your CI pipeline:
-
-```yaml
-# GitHub Actions example
-- name: Start E2E Environment
-  run: npm run docker:e2e:up
-
-- name: Run API Smoke Tests
-  run: npm run test:api:smoke:docker
-
-- name: Upload Test Reports
-  uses: actions/upload-artifact@v3
-  with:
-    name: api-smoke-reports
-    path: |
-      api-smoke-report.json
-      api-smoke-report.md
-      playwright-report/
-```
-
-## Test Coverage

-
-### Feature Flags
-- `/features` - Feature flag configuration
-
-## Reports
-
-After running tests, three reports are generated:
-
-1. **`api-smoke-report.json`** - Detailed JSON report with all test results
-2. **`api-smoke-report.md`** - Human-readable Markdown report
-3. **Playwright HTML report** - Interactive test report (in `playwright-report/`)
-
-### Report Structure
-
-```json
-{
-  "timestamp": "2024-01-07T22:00:00Z",
-  "summary": {
-    "total": 50,
-    "success": 45,
-    "failed": 5,
-    "presenterErrors": 3,
-    "avgResponseTime": 45.2
-  },
-  "results": [...],
-  "failures": [...]
-}
-```
-
-## Detecting Presenter Errors
-
-The test specifically looks for the "Presenter not presented" error pattern:
-
-```typescript
-// Detects these patterns:
-- "Presenter not presented"
-- "presenter not presented"
-- Error messages containing these phrases
-```
-
-When found, these are flagged as **presenter errors** and require immediate attention.
-
-## Troubleshooting
-
-### API Not Ready
-If tests fail because API isn't ready:
-```bash
-# Check API health
-curl http://localhost:3101/health
-
-# Wait longer in test setup (increase timeout in test file)
-```
-
-### Port Conflicts
-```bash
-# Stop conflicting services
-npm run docker:e2e:down
-
-# Check what's running
-docker-compose -f docker-compose.e2e.yml ps
-```
-
-### Missing Data
-The tests expect seeded data. If you see 404s:
-```bash
-# Ensure bootstrap is enabled
-export GRIDPILOT_API_BOOTSTRAP=1
-
-# Restart services
-npm run docker:e2e:clean && npm run docker:e2e:up
-```
-
-## Integration with Existing Tests
-
-This smoke test complements the existing test suite:
-
-- **Unit tests** (`apps/api/src/**/*Service.test.ts`) - Test individual services
-- **Integration tests** (`tests/integration/`) - Test component interactions
-- **E2E website tests** (`tests/e2e/website/`) - Test website functionality
-- **API smoke tests** (this) - Test API endpoints directly
-
-## Best Practices
-
-1. **Run before deployments** - Catch presenter errors before they reach production
-2. **Run in CI/CD** - Automated regression testing
-3. **Review reports** - Always check the generated reports
-4. **Fix presenter errors immediately** - They indicate missing `.present()` calls
-5. **Keep tests updated** - Add new endpoints as they're created
-
-## Performance
-
-- Typical runtime: 30-60 seconds
-- Parallel execution: Playwright runs tests in parallel by default
-- Response time tracking: All requests are timed
-- Average response time tracked in reports
-
-## Maintenance
-
-When adding new endpoints:
-1. Add them to the test arrays in `api-smoke.test.ts`
-2. Test locally first: `npm run test:api:smoke`
-3. Verify reports show expected results
-4. Commit updated test file
-
-When fixing presenter errors:
-1. Run smoke test to identify failing endpoints
-2. Check the specific error messages
-3. Fix the use case to call `this.output.present()` before returning
-4. Re-run smoke test to verify fix
