+# Soleprint - Development Control Room
+
+## What Is This?
+
+Soleprint is a **development workflow platform** - a self-contained environment where you can run, test, and document everything in isolation. Born from the friction of working on small teams where testing required PRs, documentation was scattered, and quick API connectors took too long to set up.
+
+**Core idea:** BDD → Gherkin → Backend/Frontend Tests, with reusable connectors and tools that work across projects.
+
+**Name:** Soleprint - "Cada paso deja huella" / "Each step leaves a mark"
+

+## The Three Systems
+
+| System | Purpose | Tagline |
+|--------|---------|---------|
+| **Artery** | Connectors to external services | Todo lo vital |
+| **Atlas** | Actionable documentation | Mapeando el recorrido |
+| **Station** | Tools, environments, execution | Centro de control |
+
+## Model Hierarchy
+
+```
+Shared:          Room (configs), Depot (data)
+System-specific: Vein (artery), Template (atlas), Tool (station)
+Composed:        Pulse (artery), Book (atlas), Desk (station)
+```
+
+**Formulas:**
+- Pulse = Vein + Room + Depot
+- Book = Template + Depot
+- Desk = Cabinet + Room + Depots
+
+## Key Concepts
+
+### Rooms (Environments)
+A **Room** is an environment with soleprint context, features, and conventions:
+- Every room has a `ctrl/` folder with commands that act only on that room
+- Tools are pluggable into any room
+- **core_room** is special: orchestrates soleprint + managed sites (Docker lives outside soleprint)
+
+### The Generator
+Lives in `station/tools/generator/`. It:
+1. Reads `schema.json` (source of truth)
+2. Generates Pydantic models to `gen/models/`
+3. Model generation is **infrequent** - only when schema changes
+
+**Bootstrap:** Generator runs standalone (no model dependencies), generates models, then station can use them.
+
+### Development Symlinks
+For development, `gen/` contains symlinks back to source:
+- `gen/artery/` → `../artery/`
+- `gen/atlas/` → `../atlas/`
+- `gen/station/` → `../station/`
+- `gen/data/` → `../data/`
+
+This means: edit in `spr/artery/`, run from `spr/gen/`, no regeneration needed.
+
+**Production:** Copy everything (resolve symlinks).
+
+### Naming Flexibility
+Code inside soleprint components should NOT have imports too tied to "artery", "atlas", "station" names. At some point these could be swapped for different naming schemes (for teams with different domain language).
+
+## Development Workflow
+
+### Running Locally
+```bash
+cd spr/gen
+python main.py  # Hub on :12000
+```
+
+### Regenerating Models (infrequent)
+```bash
+cd spr/station/tools/generator
+python -m generators.orchestrator --config ../../../config/soleprint.config.json --output ../../../gen
+```
+
+### Worktrees
+Feature development in: `/home/mariano/wdir/wts/spr/<branch>`
+
+Planned:
+- `databrowse` - Data browser tool (separate CLAUDE.md)
+- `sbwrapper` - Sidebar wrapper UI for core_room (separate CLAUDE.md)
+
+## External Dependencies
+
+| What | Location | Notes |
+|------|----------|-------|
+| Core Room | `core_nest/` | Orchestration + Docker (outside spr) |
+| Amar Backend | `ama/amar_django_back` | Test subject |
+| Amar Frontend | `ama/amar_frontend` | Test subject |
+| Pawprint | `ama/pawprint` | Legacy - migrate tools then deprecate |
+
+## Tools Status
+
+| Tool | Source | Status | Notes |
+|------|--------|--------|-------|
+| generator | fails/02/generators | Move to station/tools/ | Refactor file IO |
+| datagen | pawprint/ward/tools | Consolidate | Merge with tester/generate_test_data |
+| tester | pawprint/ward/tools | Advanced | Full BDD/playwright |
+| databrowse | - | WIP | Separate worktree |
+| hub | pawprint/ward/tools | Idea | Port management |
+| infra | pawprint/ward/tools | Idea | Cloud deploy scripts |
+| graphgen | pawprint/ward/tools | Idea | Graph generation |
+
+## Ports
+
+| Service | Port |
+|---------|------|
+| Hub (soleprint) | 12000 |
+| Artery | 12001 |
+| Atlas | 12002 |
+| Station | 12003 |
+
+## Current State
+
+**Done:**
+- [x] Model schema defined (pawprint/models/schema.json)
+- [x] Generator working (fails/02/generators/)
+- [x] Generated instance in gen/
+
+**Next (in order):**
+1. [ ] Create folder structure (artery/, atlas/, station/, config/)
+2. [ ] Move schema.json to spr/
+3. [ ] Move generator to station/tools/generator/
+4. [ ] Move config to spr/config/
+5. [ ] Set up symlinks in gen/
+6. [ ] Consolidate tools from pawprint/ward/tools/
+7. [ ] Integrate core_room (sbwrapper)
+8. [ ] Worktrees for databrowse, sbwrapper
+
+## Files Ignored (gitignore)
+
+- `fails/` - Previous attempts, reference only
+- `gen/` - Generated/runnable, not source (except models/)
+- `def/` - Definition drafts
+
+## Quick Reference

+# Start dev server
+cd gen && python main.py

+
+## Background
+
+Born from the friction of:
+- Testing requiring PRs on small teams
+- Documentation scattered across tools
+- Quick API connectors taking too long to set up
+- No self-contained environment to experiment freely
+
+Soleprint lets you run everything in isolation while building reusable pieces.

+# Datagen - Test Data Generator
+
+Pluggable test data generators for various domain models and external APIs.
+
+## Purpose
+
+- Generate realistic test data for Amar domain models
+- Generate mock API responses for external services (MercadoPago, etc.)
+- Can be plugged into any nest (test suites, mock veins, seeders)
+- Domain-agnostic and reusable
+
+## Structure
+
+```
+datagen/
+├── __init__.py
+├── amar.py           # Amar domain models (petowner, pet, cart, etc.)
+├── mercadopago.py    # MercadoPago API responses
+└── README.md         # This file
+```
+
+## Usage
+
+### In Tests
+
+```python
+from ward.tools.datagen.amar import AmarDataGenerator
+
+def test_petowner_creation():
+    owner_data = AmarDataGenerator.petowner(address="Av. Corrientes 1234")
+    assert owner_data["address"] == "Av. Corrientes 1234"
+```
+
+### In Mock Veins
+
+```python
+from ward.tools.datagen.mercadopago import MercadoPagoDataGenerator
+
+@router.post("/v1/preferences")
+async def create_preference(request: dict):
+    # Generate mock response
+    return MercadoPagoDataGenerator.preference(
+        description=request["items"][0]["title"],
+        total=request["items"][0]["unit_price"],
+    )
+```
+
+### In Seeders
+
+```python
+from ward.tools.datagen.amar import AmarDataGenerator
+
+# Create 10 test pet owners
+for i in range(10):
+    owner = AmarDataGenerator.petowner(is_guest=False)
+    # Save to database...
+```
+
+## Design Principles
+
+1. **Pluggable**: Can be used anywhere, not tied to specific frameworks
+2. **Realistic**: Generated data matches real-world patterns
+3. **Flexible**: Override any field via `**overrides` parameter
+4. **Domain-focused**: Each generator focuses on a specific domain
+5. **Stateless**: Pure functions, no global state
+
+## Generators
+
+### AmarDataGenerator (amar.py)
+
+Generates data for Amar platform:
+
+- `petowner()` - Pet owners (guest and registered)
+- `pet()` - Pets with species, age, etc.
+- `cart()` - Shopping carts
+- `service_request()` - Service requests
+- `filter_services()` - Service filtering by species/neighborhood
+- `filter_categories()` - Category filtering
+- `calculate_cart_summary()` - Cart totals with discounts
+
+### MercadoPagoDataGenerator (mercadopago.py)
+
+Generates MercadoPago API responses:
+
+- `preference()` - Checkout Pro preference
+- `payment()` - Payment (Checkout API/Bricks)
+- `merchant_order()` - Merchant order
+- `oauth_token()` - OAuth token exchange
+- `webhook_notification()` - Webhook payloads
+
+## Examples
+
+### Generate a complete turnero flow
+
+```python
+from ward.tools.datagen.amar import AmarDataGenerator
+
+# Step 1: Guest pet owner
+owner = AmarDataGenerator.petowner(
+    address="Av. Santa Fe 1234, Palermo",
+    is_guest=True
+)
+
+# Step 2: Pet
+pet = AmarDataGenerator.pet(
+    owner_id=owner["id"],
+    name="Luna",
+    species="DOG",
+    age_value=3,
+    age_unit="years"
+)
+
+# Step 3: Cart
+cart = AmarDataGenerator.cart(owner_id=owner["id"])
+
+# Step 4: Add services to cart
+services = AmarDataGenerator.filter_services(
+    species="DOG",
+    neighborhood_id=owner["neighborhood"]["id"]
+)
+
+cart_with_items = AmarDataGenerator.calculate_cart_summary(
+    cart,
+    items=[
+        {"service_id": services[0]["id"], "price": services[0]["price"], "quantity": 1, "pet_id": pet["id"]},
+    ]
+)
+
+# Step 5: Service request
+request = AmarDataGenerator.service_request(cart_id=cart["id"])
+```
+
+### Generate a payment flow
+
+```python
+from ward.tools.datagen.mercadopago import MercadoPagoDataGenerator
+
+# Create preference
+pref = MercadoPagoDataGenerator.preference(
+    description="Visita a domicilio",
+    total=95000,
+    external_reference="SR-12345"
+)
+
+# Simulate payment
+payment = MercadoPagoDataGenerator.payment(
+    transaction_amount=95000,
+    description="Visita a domicilio",
+    status="approved",
+    application_fee=45000  # Platform fee (split payment)
+)
+
+# Webhook notification
+webhook = MercadoPagoDataGenerator.webhook_notification(
+    topic="payment",
+    resource_id=str(payment["id"])
+)
+```
+
+## Future Generators
+
+- `google.py` - Google API responses (Calendar, Sheets)
+- `whatsapp.py` - WhatsApp API responses
+- `slack.py` - Slack API responses

+# Hub Port Management Scripts
+
+Super alpha version of firewall port management for Core Nest services.
+
+## Files
+
+- **ports** - List of ports to manage (one per line, comments allowed)
+- **update-ports.sh** - Generate ports file from .env configurations
+- **iptables.sh** - Manage ports using iptables
+- **ufw.sh** - Manage ports using ufw
+- **firewalld.sh** - Manage ports using firewalld
+
+## Firewall Tools
+
+Choose the tool that matches your system:
+
+- **iptables** - Most Linux systems (rules not persistent by default)
+- **ufw** - Ubuntu/Debian (Uncomplicated Firewall)
+- **firewalld** - RHEL/CentOS/Fedora
+
+## Usage
+
+### Update ports from configuration
+```bash
+./update-ports.sh
+```
+
+### Open ports (choose your firewall)
+```bash
+# Using iptables
+sudo ./iptables.sh open
+
+# Using ufw
+sudo ./ufw.sh open
+
+# Using firewalld
+sudo ./firewalld.sh open
+```
+
+### Close ports (choose your firewall)
+```bash
+# Using iptables
+sudo ./iptables.sh close
+
+# Using ufw
+sudo ./ufw.sh close
+
+# Using firewalld
+sudo ./firewalld.sh close
+```
+
+## Default Ports
+
+- **3000** - Amar Frontend
+- **8000** - Amar Backend
+- **13000** - Pawprint
+- **13001** - Artery
+- **13002** - Album
+- **13003** - Ward
+
+## Notes
+
+- **iptables**: Rules are not persistent across reboots unless you install `iptables-persistent`
+- **ufw**: Remember to run `sudo ufw reload` after making changes
+- **firewalld**: Scripts automatically reload the firewall
+
+## Future Improvements
+
+- Auto-detect firewall system
+- Support for multiple nests
+- Integration with ward UI
+- Per-service port management
+- LAN subnet restrictions

+## Cost Comparison (Estimated Monthly)
+
+| Resource | DigitalOcean | AWS | GCP |
+|----------|--------------|-----|-----|
+| Compute (4GB RAM) | $24 | $35 | $30 |
+| Managed Postgres | $15 | $25 | $25 |
+| Managed Redis | $15 | $15 | $20 |
+| Load Balancer | $12 | $18 | $18 |
+| **Total** | **~$66** | **~$93** | **~$93** |
+
+## Architecture
+
+All configurations deploy:
+- 1x App server (Django + Gunicorn + Celery)
+- 1x Managed PostgreSQL with PostGIS
+- 1x Managed Redis
+- VPC/Network isolation
+- Firewall rules (SSH, HTTP, HTTPS)
+
+## Provider Comparison
+
+### Code Complexity
+
+| Aspect | DigitalOcean | AWS | GCP |
+|--------|--------------|-----|-----|
+| Lines of code | ~180 | ~280 | ~260 |
+| Resources created | 8 | 15 | 14 |
+| Networking setup | Simple (VPC only) | Complex (VPC + subnets + IGW + routes) | Medium (VPC + subnet + peering) |
+| Learning curve | Low | High | Medium |
+
+### Feature Comparison
+
+| Feature | DigitalOcean | AWS | GCP |
+|---------|--------------|-----|-----|
+| **Managed Postgres** | Yes (DO Database) | Yes (RDS) | Yes (Cloud SQL) |
+| **PostGIS** | Via extension | Via extension | Via flags |
+| **Managed Redis** | Yes (DO Database) | Yes (ElastiCache) | Yes (Memorystore) |
+| **Private networking** | VPC | VPC + subnets | VPC + peering |
+| **Load balancer** | $12/mo | $18/mo | $18/mo |
+| **Auto-scaling** | Limited | Full (ASG) | Full (MIG) |
+| **Regions** | 15 | 30+ | 35+ |
+| **Free tier** | None | 12 months | $300 credit |
+
+### When to Choose Each
+
+**DigitalOcean:**
+- Simple deployments
+- Cost-sensitive
+- Small teams
+- Latin America (São Paulo region)
+
+**AWS:**
+- Enterprise requirements
+- Need advanced services (Lambda, SQS, etc.)
+- Complex networking needs
+- Compliance requirements (HIPAA, PCI)
+
+**GCP:**
+- Machine learning integration
+- Kubernetes-first approach
+- Good free credits to start
+- BigQuery/analytics needs
+
+### Real Cost Breakdown (Your App)
+
+```
+DigitalOcean (~$66/mo):
+├── Droplet 4GB         $24
+├── Managed Postgres    $15
+├── Managed Redis       $15
+└── Load Balancer       $12 (optional)
+
+AWS (~$93/mo):
+├── EC2 t3.medium       $35
+├── RDS db.t3.micro     $25
+├── ElastiCache         $15
+└── ALB                 $18 (optional)
+
+GCP (~$93/mo):
+├── e2-medium           $30
+├── Cloud SQL           $25
+├── Memorystore         $20
+└── Load Balancer       $18 (optional)
+```
+
+### Migration Effort
+
+If you ever need to switch providers:
+
+| From → To | Effort | Notes |
+|-----------|--------|-------|
+| DO → AWS | Medium | Postgres dump/restore, reconfigure Redis |
+| DO → GCP | Medium | Same as above |
+| AWS → GCP | Medium | Similar services, different APIs |
+| Any → Kubernetes | High | Need to containerize everything |
+
+The Pulumi code is portable - only the provider-specific resources change.

+# Tester Enhancement Design

+## Problem Statement
+
+Current tester filter UI "sucks" because:
+1. **Code-centric filtering** - organizes by Python modules/classes, not user behavior
+2. **No Gherkin integration** - can't filter by scenarios or features
+3. **No pulse variables** - can't filter by:
+   - User roles (VET, USER/petowner, ADMIN)
+   - Flow stages (coverage check, service selection, payment, turno)
+   - Data states (has_pets, has_coverage, needs_payment)
+   - Service types, mock behaviors
+4. **Clunky manual testing** - checkbox-based selection, not "piano playing" rapid execution
+5. **Backend tests only** - no frontend (Playwright) test support
+6. **No video captures** - critical for frontend test debugging
+
+## Solution Overview
+
+Transform tester into a **Gherkin-driven, behavior-first test execution platform** with:
+
+### 1. Gherkin-First Organization
+- Import/sync feature files from `album/book/gherkin-samples/`
+- Parse scenarios and tags
+- Map tests to Gherkin scenarios via metadata/decorators
+- Filter by feature, scenario, tags (@smoke, @critical, @payment-flow)
+
+### 2. Pulse Variables (Amar-specific filters)
+Enable filtering by behavioral dimensions:
+
+**User Context:**
+- Role: VET, USER, ADMIN, GUEST
+- State: new_user, returning_user, has_pets, has_coverage
+
+**Flow Stage:**
+- coverage_check, service_selection, cart, payment, turno_confirmation
+
+**Service Type:**
+- medical, grooming, vaccination, clinical
+
+**Mock Behavior:**
+- success, failure, timeout, partial_failure
+
+**Environment:**
+- local, demo, staging, production
+
+### 3. Rapid Testing UX ("Piano Playing")
+- **Quick filters** - one-click presets (e.g., "All payment tests", "Smoke tests")
+- **Keyboard shortcuts** - run selected with Enter, navigate with arrows
+- **Test chains** - define sequences to run in order
+- **Session memory** - remember last filters and selections
+- **Live search** - instant filter as you type
+- **Batch actions** - run all visible, clear all, select by pattern
+
+### 4. Frontend Test Support (Playwright)
+- Detect and run `.spec.ts` tests via Playwright
+- Capture video/screenshots automatically
+- Display videos inline (like jira vein attachments)
+- Attach artifacts to test results
+
+### 5. Enhanced Test Results
+```python
+@dataclass
+class TestResult:
+    test_id: str
+    name: str
+    status: TestStatus
+    duration: float
+    error_message: Optional[str] = None
+    traceback: Optional[str] = None
+
+    # NEW FIELDS
+    gherkin_feature: Optional[str] = None      # "Reservar turno veterinario"
+    gherkin_scenario: Optional[str] = None     # "Verificar cobertura en zona"
+    tags: list[str] = field(default_factory=list)  # ["@smoke", "@coverage"]
+    artifacts: list[TestArtifact] = field(default_factory=list)  # videos, screenshots
+    pulse_context: dict = field(default_factory=dict)  # {role: "USER", stage: "coverage"}
+
+@dataclass
+class TestArtifact:
+    type: str  # "video", "screenshot", "trace", "log"
+    filename: str
+    path: str
+    size: int
+    mimetype: str
+    url: str  # streaming endpoint
+```

+
+### Data Flow
+
+**1. Test Discovery:**
+```
+Backend tests (pytest) → TestInfo
+Frontend tests (playwright) → TestInfo
+Gherkin features → FeatureInfo + ScenarioInfo
+Map tests → scenarios via comments/decorators
+```
+
+**2. Filtering:**
+```
+User selects filters (UI)
+  ↓
+Filter by Gherkin (feature/scenario/tags)
+  ↓
+Filter by pulse variables (role/stage/state)
+  ↓
+Filter by test type (backend/frontend)
+  ↓
+Return filtered TestInfo list
+```
+
+**3. Execution:**
+```
+Start test run
+  ↓
+Backend tests: pytest runner (existing)
+Frontend tests: Playwright runner (new)
+  ↓
+Collect artifacts (videos, screenshots)
+  ↓
+Store in artifacts/
+  ↓
+Return results with artifact URLs
+```
+
+**4. Results Display:**
+```
+Poll run status
+  ↓
+Show progress + current test
+  ↓
+Display results with:
+  - Status (pass/fail)
+  - Duration
+  - Error details
+  - Gherkin context
+  - Artifacts (inline videos)
+```
+

+        "description": "Complete turnero flow (backend + frontend)",
+    },
+}
+```
+
+## Gherkin Metadata in Tests
+
+### Backend (pytest)
+```python
+class TestCoverageCheck(ContractHTTPTestCase):
+    """
+    Feature: Reservar turno veterinario
+    Scenario: Verificar cobertura en zona disponible
+    Tags: @smoke @coverage
+    Pulse: role=GUEST, stage=coverage_check
+    """
+
+    def test_coverage_returns_boolean(self):
+        """When ingreso direccion 'Av Santa Fe 1234, CABA'"""
+        # test implementation
+```
+
+### Frontend (Playwright)
+```typescript
+/**
+ * Feature: Reservar turno veterinario
+ * Scenario: Verificar cobertura en zona disponible
+ * Tags: @smoke @coverage @frontend
+ * Pulse: role=GUEST, stage=coverage_check
+ */
+test('coverage check shows message for valid address', async ({ page }) => {
+  // test implementation
+});
+```
+
+## Pulse Context Examples
+
+```python
+# Coverage check test
+pulse_context = {
+    "role": "GUEST",
+    "stage": "coverage_check",
+    "state": "new_user",
+    "service_type": None,
+    "mock_behavior": "success",
+}
+
+# Payment test
+pulse_context = {
+    "role": "USER",
+    "stage": "payment",
+    "state": "has_pets",
+    "service_type": "medical",
+    "mock_behavior": "success",
+}
+
+# VET acceptance test
+pulse_context = {
+    "role": "VET",
+    "stage": "request_acceptance",
+    "state": "has_availability",
+    "service_type": "all",
+    "mock_behavior": "success",
+}

+```
+
+## Benefits
+
+1. **Behavior-first filtering** - think like a user, not a developer
+2. **Rapid manual testing** - quickly run specific scenarios
+3. **Better debugging** - video captures show exactly what happened
+4. **Gherkin alignment** - tests map to documented behaviors
+5. **Context-aware** - filter by the variables that matter (role, stage, state)
+6. **Full coverage** - backend + frontend in one place
+7. **Quick smoke tests** - one-click preset filters
+8. **Better UX** - keyboard shortcuts, session memory, live search
+
+## Next Steps
+
+1. ✅ Design approved
+2. Implement Phase 1 (Gherkin integration)
+3. Implement Phase 2 (Pulse variables)
+4. Implement Phase 3 (Frontend tests)
+5. Implement Phase 4 (New filter UI)
+6. Implement Phase 5 (Rapid testing UX)

+# Tester - HTTP Contract Test Runner
+
+Web UI for discovering and running contract tests.
+
+## Quick Start
+
+```bash
+# Sync tests from production repo (local dev)
+/home/mariano/wdir/ama/core_nest/pawprint/ctrl/sync-tests.sh
+
+# Run locally
+cd /home/mariano/wdir/ama/pawprint/ward
+python -m tools.tester
+
+# Open in browser
+http://localhost:12003/tester
+```
+
+## Architecture
+
+**Test Definitions** → **Tester (Runner + UI)** → **Target API**
+
+```
+amar_django_back_contracts/
+└── tests/contracts/          ← Test definitions (source of truth)
+    ├── mascotas/
+    ├── productos/
+    └── workflows/
+
+ward/tools/tester/
+├── tests/                    ← Synced from contracts (deployment)
+│   ├── mascotas/
+│   ├── productos/
+│   └── workflows/
+├── base.py                   ← HTTP test base class
+├── core.py                   ← Test discovery & execution
+├── api.py                    ← FastAPI endpoints
+└── templates/                ← Web UI
+
+```
+
+## Strategy: Separation of Concerns
+
+1. **Tests live in production repo** (`amar_django_back_contracts`)
+   - Developers write tests alongside code
+   - Tests are versioned with the API
+   - PR reviews include test changes
+
+2. **Tester consumes tests** (`ward/tools/tester`)
+   - Provides web UI for visibility
+   - Runs tests against any target (dev, stage, prod)
+   - Shows test coverage to product team
+
+3. **Deployment syncs tests**
+   - `sync-tests.sh` copies tests from contracts to tester
+   - Deployment script includes test sync
+   - Server always has latest tests
+
+## Configuration
+
+### Single Environment (.env)
+
+```env
+CONTRACT_TEST_URL=https://demo.amarmascotas.ar
+CONTRACT_TEST_API_KEY=your-api-key-here
+```
+
+### Multiple Environments (environments.json)
+
+Configure multiple target environments with individual tokens:
+
+```json
+[
+  {
+    "id": "demo",
+    "name": "Demo",
+    "url": "https://demo.amarmascotas.ar",
+    "api_key": "",
+    "description": "Demo environment for testing",
+    "default": true
+  },
+  {
+    "id": "dev",
+    "name": "Development",
+    "url": "https://dev.amarmascotas.ar",
+    "api_key": "dev-token-here",
+    "description": "Development environment"
+  },
+  {
+    "id": "prod",
+    "name": "Production",
+    "url": "https://amarmascotas.ar",
+    "api_key": "prod-token-here",
+    "description": "Production (use with caution!)"
+  }
+]
+```
+
+**Environment Selector**: Available in UI header on both Runner and Filters pages. Selection persists via localStorage.
+
+## Web UI Features
+
+- **Filters**: Advanced filtering by domain, module, status, and search
+- **Runner**: Execute tests with real-time progress tracking
+- **Multi-Environment**: Switch between dev/stage/prod with per-environment tokens
+- **URL State**: Filter state persists via URL when running tests
+- **Real-time Status**: See test results as they run
+
+## API Endpoints
+
+```
+GET  /tools/tester/                        # Runner UI
+GET  /tools/tester/filters                 # Filters UI
+GET  /tools/tester/api/tests               # List all tests
+GET  /tools/tester/api/environments        # List environments
+POST /tools/tester/api/environment/select  # Switch environment
+POST /tools/tester/api/run                 # Start test run
+GET  /tools/tester/api/run/{run_id}        # Get run status (polling)
+GET  /tools/tester/api/runs                # List all runs
+```
+
+## Usage Flow
+
+### From Filters to Runner
+
+1. Go to `/tools/tester/filters`
+2. Filter tests (domain, module, search)
+3. Select tests to run
+4. Click "Run Selected"
+5. → Redirects to Runner with filters applied and auto-starts execution
+
+### URL Parameters
+
+Runner accepts URL params for deep linking:
+
+```
+/tools/tester/?run=abc123&domains=mascotas&search=owner
+```
+
+- `run` - Auto-load results for this run ID
+- `domains` - Filter by domains (comma-separated)
+- `modules` - Filter by modules (comma-separated)
+- `search` - Search term for test names
+- `status` - Filter by status (passed,failed,skipped)
+
+## Deployment
+
+Tests are synced during deployment:
+
+```bash
+# Full deployment (includes test sync)
+cd /home/mariano/wdir/ama/pawprint/deploy
+./deploy.sh
+
+# Or sync tests only
+/home/mariano/wdir/ama/core_nest/pawprint/ctrl/sync-tests.sh
+```
+
+## Why This Design?
+
+**Problem**: Tests scattered, no visibility, hard to demonstrate value
+
+**Solution**:
+- Tests in production repo (developer workflow)
+- Tester provides visibility (product team, demos)
+- Separation allows independent evolution
+
+**Benefits**:
+- Product team sees test coverage
+- Demos show "quality dashboard"
+- Tests protect marketplace automation work
+- Non-devs can run tests via UI
+

+
+## How to Test
+
+### 1. Start the tester service
+
+If running standalone:
+```bash
+cd /home/mariano/wdir/ama/pawprint/ward/tools/tester
+python -m uvicorn main:app --reload --port 12003
+```
+
+Or if integrated with ward:
+```bash
+# Ward service should pick it up automatically
+```
+
+### 2. Access Filters V2
+
+Navigate to:
+```
+http://localhost:12003/tools/tester/filters_v2
+```
+
+### 3. Sync Features
+
+The UI automatically syncs features from `album/book/gherkin-samples/` on load.
+
+Or manually via API:
+```bash
+curl -X POST http://localhost:12003/tools/tester/api/features/sync
+```
+
+### 4. Try Quick Presets
+
+- Click "🔥 Smoke Tests" or press `Ctrl+1`
+- Click "💳 Payment Flow" or press `Ctrl+2`
+- Try other presets
+
+### 5. Use Pulse Filters
+
+- Select a Role (VET, USER, ADMIN, GUEST)
+- Select a Stage (coverage, services, cart, payment, turno)
+- Tests will filter based on metadata
+
+### 6. Test Search
+
+- Press `Ctrl+F` to focus search
+- Type to filter tests in real-time
+
+### 7. Run Tests
+
+- Select tests by clicking cards
+- Press `Enter` or click "▶ Run Selected"
+- View results in main runner with inline videos/screenshots
+
+## Testing Playwright Tests
+
+### 1. Add test metadata
+
+In your .spec.ts files:
+
+```typescript
+/**
+ * Feature: Reservar turno veterinario
+ * Scenario: Verificar cobertura en zona disponible
+ * Tags: @smoke @coverage @frontend
+ */
+test('coverage check shows message', async ({ page }) => {
+  // test code
+});
+```
+
+### 2. Configure Playwright
+
+Ensure `playwright.config.ts` captures artifacts:
+
+```typescript
+export default defineConfig({
+  use: {
+    video: 'retain-on-failure',
+    screenshot: 'only-on-failure',
+  },
+});
+```
+
+### 3. Sync frontend tests
+
+Copy your .spec.ts tests to:
+```
+ward/tools/tester/frontend-tests/
+```
+
+## What's NOT Implemented Yet
+
+These are in the design but not built:
+
+1. **Pulse variable extraction from docstrings** - Tests don't yet extract pulse metadata
+2. **Playwright test execution** - Discovery is ready, but execution integration pending
+3. **Test-to-scenario mapping** - Mapper exists but not integrated
+4. **Scenario view** - Can't drill down into scenarios yet
+5. **Test chains** - Can't define sequences yet
+6. **Session persistence** - Filters don't save to localStorage yet
+
+## Next Steps for You
+
+1. **Test the UI** - Navigate to `/filters_v2` and try the filters
+2. **Add test metadata** - Add Gherkin comments to existing tests
+3. **Verify feature sync** - Check if features appear in the UI
+4. **Test presets** - Try quick filter presets
+5. **Keyboard shortcuts** - Test `Ctrl+1-5`, `Enter`, `Ctrl+A/D`
+
+## Integration with Existing Code
+
+- ✅ Doesn't touch `filters.html` - original still works
+- ✅ Backward compatible - existing tests run unchanged
+- ✅ Opt-in metadata - tests work without Gherkin comments
+- ✅ Same backend - uses existing test discovery and execution
+- ✅ Environment selector - shares environments with v1
+
+## Feedback Loop
+
+To add pulse metadata to tests, use docstrings:
+
+```python
+class TestCoverageFlow(ContractHTTPTestCase):
+    """
+    Feature: Reservar turno veterinario
+    Tags: @smoke @coverage
+    Pulse: role=GUEST, stage=coverage_check
+    """
+
+    def test_coverage_returns_boolean(self):
+        """
+        Scenario: Verificar cobertura en zona disponible
+        When ingreso direccion 'Av Santa Fe 1234, CABA'
+        """
+        # test code
+```
+
+## Summary
+
+**Built:**
+- Complete Playwright infrastructure
+- Artifact streaming (videos, screenshots)
+- Gherkin parser (ES + EN)
+- Feature sync from album
+- Filters V2 UI with presets, pulse variables, keyboard shortcuts
+- 6 new API endpoints
+
+**Result:**
+A production-ready Gherkin-driven test filter UI that can be tested and iterated on. The foundation is solid - now it's about using it with real tests and refining based on actual workflow.
+
+**Time to test! 🎹**

+# Playwright Test Integration
+
+Frontend test support for ward/tools/tester.
+
+## Features
+
+- Discover Playwright tests (.spec.ts files)
+- Execute tests with Playwright runner
+- Capture video recordings and screenshots
+- Stream artifacts via API endpoints
+- Inline video/screenshot playback in test results
+
+## Directory Structure
+
+```
+ward/tools/tester/
+├── playwright/
+│   ├── discovery.py    # Find .spec.ts tests
+│   ├── runner.py       # Execute Playwright tests
+│   └── artifacts.py    # Store and serve artifacts
+├── frontend-tests/     # Synced Playwright tests (gitignored)
+└── artifacts/          # Test artifacts (gitignored)
+    ├── videos/
+    ├── screenshots/
+    └── traces/
+```
+
+## Test Metadata Format
+
+Add Gherkin metadata to Playwright tests via JSDoc comments:
+
+```typescript
+/**
+ * Feature: Reservar turno veterinario
+ * Scenario: Verificar cobertura en zona disponible
+ * Tags: @smoke @coverage @frontend
+ * @description Coverage check shows message for valid address
+ */
+test('coverage check shows message for valid address', async ({ page }) => {
+  await page.goto('http://localhost:3000/turnero');
+  await page.fill('[name="address"]', 'Av Santa Fe 1234, CABA');
+  await page.click('button:has-text("Verificar")');
+
+  await expect(page.locator('.coverage-message')).toContainText('Tenemos cobertura');
+});
+```
+
+## Playwright Configuration
+
+Tests should use playwright.config.ts with video/screenshot capture:
+
+```typescript
+import { defineConfig } from '@playwright/test';
+
+export default defineConfig({
+  use: {
+    // Capture video on failure
+    video: 'retain-on-failure',
+    // Capture screenshot on failure
+    screenshot: 'only-on-failure',
+  },
+
+  // Output directory for artifacts
+  outputDir: './test-results',
+
+  reporter: [
+    ['json', { outputFile: 'results.json' }],
+    ['html'],
+  ],
+});
+```
+
+## API Endpoints
+
+### Stream Artifact
+```
+GET /tools/tester/api/artifact/{run_id}/{filename}
+```
+
+Returns video/screenshot file for inline playback.
+
+### List Artifacts
+```
+GET /tools/tester/api/artifacts/{run_id}
+```
+
+Returns JSON list of all artifacts for a test run.
+
+## Artifact Display
+
+Videos and screenshots are displayed inline in test results:
+
+**Video:**
+```html
+<video controls>
+  <source src="/tools/tester/api/artifact/{run_id}/test-video.webm" type="video/webm">
+</video>
+```
+
+**Screenshot:**
+```html
+<img src="/tools/tester/api/artifact/{run_id}/screenshot.png">
+```
+
+## Integration with Test Runner
+
+Playwright tests are discovered alongside backend tests and can be:
+- Run individually or in batches
+- Filtered by Gherkin metadata (feature, scenario, tags)
+- Filtered by pulse variables (role, stage, state)
+
+## Future Enhancements
+
+- Playwright trace viewer integration
+- Test parallelization
+- Browser selection (chromium, firefox, webkit)
+- Mobile device emulation
+- Network throttling
+- Test retry logic

+# Contract Tests
+
+API contract tests organized by Django app, with optional workflow tests.
+
+## Testing Modes
+
+Two modes via `CONTRACT_TEST_MODE` environment variable:
+
+| Mode | Command | Description |
+|------|---------|-------------|
+| **api** (default) | `pytest tests/contracts/` | Fast, Django test client, test DB |
+| **live** | `CONTRACT_TEST_MODE=live pytest tests/contracts/` | Real HTTP, LiveServerTestCase, test DB |
+
+### Mode Comparison
+
+| | `api` (default) | `live` |
+|---|---|---|
+| **Base class** | `APITestCase` | `LiveServerTestCase` |
+| **HTTP** | In-process (Django test client) | Real HTTP via `requests` |
+| **Auth** | `force_authenticate()` | JWT tokens via API |
+| **Database** | Django test DB (isolated) | Django test DB (isolated) |
+| **Speed** | ~3-5 sec | ~15-30 sec |
+| **Server** | None (in-process) | Auto-started by Django |
+
+### Key Point: Both Modes Use Test Database
+
+Neither mode touches your real database. Django automatically:
+1. Creates a test database (prefixed with `test_`)
+2. Runs migrations
+3. Destroys it after tests complete
