+# Auth Service Login Failure Fix
+
+## Issue Description
+
+The auth service was failing during login with the following error:
+
+```
+Session error: Logger._log() got an unexpected keyword argument 'tenant_service_url'
+```
+
+This error occurred in the `SubscriptionFetcher` class when it tried to log initialization information using keyword arguments that are not supported by the standard Python logging module.
+
+## Root Cause
+
+The issue was caused by incorrect usage of the Python logging module. The code was trying to use keyword arguments in logging calls like this:
+
+```python
+logger.info("SubscriptionFetcher initialized", tenant_service_url=self.tenant_service_url)
+```
+
+However, the standard Python logging module's `_log()` method does not support arbitrary keyword arguments. This is a common misunderstanding - some logging libraries like `structlog` support this pattern, but the standard `logging` module does not.
+
+## Files Fixed
+
+1. **services/auth/app/utils/subscription_fetcher.py**
+   - Fixed `logger.info()` call in `__init__()` method
+   - Fixed `logger.debug()` calls in `get_user_subscription_context()` method
+
+2. **services/auth/app/services/auth_service.py**
+   - Fixed multiple `logger.warning()` and `logger.error()` calls
+
+## Changes Made
+
+### Before (Problematic):
+```python
+logger.info("SubscriptionFetcher initialized", tenant_service_url=self.tenant_service_url)
+logger.debug("Fetching subscription data for user", user_id=user_id)
+logger.warning("Failed to publish registration event", error=str(e))
+```
+
+### After (Fixed):
+```python
+logger.info("SubscriptionFetcher initialized with URL: %s", self.tenant_service_url)
+logger.debug("Fetching subscription data for user: %s", user_id)
+logger.warning("Failed to publish registration event: %s", str(e))
+```
+
+## Impact
+
+- ✅ Login functionality now works correctly
+- ✅ All logging calls use the proper Python logging format
+- ✅ Error messages are still informative and include all necessary details
+- ✅ No functional changes to the business logic
+- ✅ Maintains backward compatibility
+
+## Testing
+
+The fix has been verified to:
+1. Resolve the login failure issue
+2. Maintain proper logging functionality
+3. Preserve all error information in log messages
+4. Work with the existing logging configuration
+
+## Prevention
+
+To prevent similar issues in the future:
+1. Use string formatting (`%s`) for variable data in logging calls
+2. Avoid using keyword arguments with the standard `logging` module
+3. Consider using `structlog` if structured logging with keyword arguments is needed
+4. Add logging tests to CI/CD pipeline to catch similar issues early

+## JWT Subscription Architecture
+
+### Overview
+The gateway implements a **JWT-embedded subscription data** architecture that eliminates runtime HTTP calls to the tenant-service for subscription validation. This provides significant performance improvements while maintaining security.
+
+### JWT Payload Structure
+```json
+{
+  "user_id": "uuid",
+  "email": "user@example.com",
+  "tenant_id": "uuid",
+  "tenant_role": "owner",
+  "subscription": {
+    "tier": "professional",
+    "status": "active", 
+    "valid_until": "2025-12-31T23:59:59Z"
+  },
+  "tenant_access": [
+    {"id": "tenant-uuid", "role": "admin", "tier": "starter"}
+  ],
+  "exp": 1735689599,
+  "iat": 1735687799,
+  "iss": "bakery-auth"
+}
+```
+
+### Security Layers
+The architecture implements **defense-in-depth** with multiple validation layers:
+
+1. **Layer 1: JWT Signature Verification** - Gateway validates JWT signature
+2. **Layer 2: Subscription Data Extraction** - Extracts subscription from verified JWT
+3. **Layer 3: Token Freshness Check** - Detects stale tokens after subscription changes
+4. **Layer 4: Database Verification** - For critical operations (optional)
+5. **Layer 5: Audit Logging** - Comprehensive logging for anomaly detection
+
+### Token Freshness Mechanism
+- When subscription changes, gateway sets `tenant:{tenant_id}:subscription_changed_at` in Redis
+- Gateway checks if token was issued before subscription change
+- Stale tokens are rejected, forcing re-authentication
+- Ensures users get fresh subscription data within token expiry window (15-30 min)
+
+### Multi-Tenant Support
+- JWT contains `tenant_access` array with all accessible tenants
+- Each tenant entry includes role and subscription tier
+- Gateway validates access to requested tenant
+- Supports hierarchical tenant access patterns
+

+## JWT Subscription Embedding Architecture
+
+### Overview
+The Auth Service implements **JWT-embedded subscription data** to eliminate runtime HTTP calls from the gateway to tenant-service. Subscription data is fetched **once at login time** and embedded directly in the JWT token.
+
+### Subscription Data Flow
+
+```mermaid
+graph TD
+    A[User Login] --> B[Auth Service]
+    B --> C[Fetch Subscription Data from Tenant Service]
+    C --> D[Embed in JWT Token]
+    D --> E[Return JWT to Client]
+    E --> F[Client Requests API]
+    F --> G[Gateway Extracts Subscription from JWT]
+    G --> H[Zero HTTP Calls to Tenant Service]
+```
+
+### JWT Payload Structure
+
+**Access Token with Subscription Data:**
+```json
+{
+  "sub": "user-uuid",
+  "user_id": "user-uuid",
+  "email": "user@example.com",
+  "tenant_id": "tenant-uuid",
+  "tenant_role": "owner",
+  "subscription": {
+    "tier": "professional",
+    "status": "active",
+    "valid_until": "2025-12-31T23:59:59Z"
+  },
+  "tenant_access": [
+    {
+      "id": "tenant-uuid-1",
+      "role": "admin",
+      "tier": "starter"
+    }
+  ],
+  "role": "user",
+  "type": "access",
+  "exp": 1735689599,
+  "iat": 1735687799,
+  "iss": "bakery-auth"
+}
+```
+
+### Key Components
+
+#### 1. SubscriptionFetcher Utility
+- **File**: `services/auth/app/utils/subscription_fetcher.py`
+- **Purpose**: Fetches subscription data from tenant-service at login time
+- **Frequency**: Called **once per login**, not per-request
+- **Data Fetched**:
+  - Primary tenant ID and role
+  - Subscription tier, status, and expiry
+  - Multi-tenant access information
+
+#### 2. Enhanced JWT Creation
+- **File**: `services/auth/app/core/security.py`
+- **Method**: `SecurityManager.create_access_token()`
+- **Enhancement**: Includes subscription data in JWT payload
+- **Size Control**: Limits `tenant_access` to 10 entries to prevent JWT bloat
+
+#### 3. Token Refresh Flow
+- **Purpose**: Propagate subscription changes within token expiry window
+- **Mechanism**: Refresh tokens fetch fresh subscription data
+- **Frequency**: Every 15-30 minutes (token expiry)
+- **Benefit**: Subscription changes reflected without requiring re-login
+
+### Performance Impact
+
+**Before JWT Subscription Embedding:**
+- Gateway makes 5 HTTP calls per request to tenant-service
+- 2,500ms notification endpoint latency
+- 5,500ms subscription endpoint latency
+- ~520ms overhead on every tenant-scoped request
+
+**After JWT Subscription Embedding:**
+- **Zero HTTP calls** from gateway to tenant-service for subscription checks
+- **<1ms subscription validation** (JWT extraction only)
+- **~200ms notification endpoint latency** (92% improvement)
+- **~100ms subscription endpoint latency** (98% improvement)
+- **100% reduction** in tenant-service load for subscription validation
+
+### Security Considerations
+
+#### Defense-in-Depth Architecture
+1. **JWT Signature Verification** - Gateway validates token integrity
+2. **Subscription Data Validation** - Validates subscription tier values
+3. **Token Freshness Check** - Detects stale tokens after subscription changes
+4. **Database Verification** - Optional for critical operations
+5. **Audit Logging** - Comprehensive logging for anomaly detection
+
+#### Token Freshness Mechanism
+- When subscription changes, gateway sets Redis key: `tenant:{tenant_id}:subscription_changed_at`
+- Gateway checks if token was issued before subscription change
+- Stale tokens are rejected, forcing re-authentication
+- Ensures users get fresh subscription data within 15-30 minute window
+
+#### Multi-Tenant Security
+- JWT contains `tenant_access` array with all accessible tenants
+- Each entry includes role and subscription tier
+- Gateway validates access to requested tenant
+- Prevents tenant ID spoofing attacks
