+# URGENT: Production Migration Required - delivery_type Validation Failure
+
+## Issue Summary
+
+**Status:** 🔴 BLOCKING PRODUCTION
+**Date Discovered:** 2025-10-16
+**Affected Systems:** All production sales agents (Wonderstruck, Test Agent, etc.)
+
+### Problem
+
+Production databases contain products with invalid `delivery_type` values:
+- **Current (invalid):** `'non-guaranteed'` (hyphen)
+- **Required (spec-compliant):** `'non_guaranteed'` (underscore)
+
+This causes **all `get_products` calls to fail** with validation errors:
+
+```
+Product 'prod_e8fd6012' in database failed AdCP schema validation.
+Error: 1 validation error for Product
+delivery_type
+  Input should be 'guaranteed' or 'non_guaranteed' [type=literal_error, input_value='non-guaranteed', input_type=str]
+```
+
+### Root Cause
+
+1. **AdCP Spec** defines delivery_type enum as: `["guaranteed", "non_guaranteed"]` (underscore)
+2. **Historic Data** used hyphenated format: `'non-guaranteed'`
+3. **Schema Enforcement** now strictly validates per AdCP spec (src/core/schemas.py:654)
+4. **Migration Exists** (`f9300bf2246d`) but **hasn't been run on production**
+
+## Impact
+
+- ❌ `get_products` fails for all agents
+- ❌ Product discovery broken
+- ❌ Cannot create new media buys (no products available)
+- ❌ Wonderstruck integration test failing
+- ❌ All AdCP workflows blocked
+
+## Solution
+
+### Migration Details
+
+**File:** `alembic/versions/f9300bf2246d_fix_delivery_type_values_hyphen_to_.py`
+**Revision:** `f9300bf2246d`
+**Depends On:** `2453043b72da`
+**Created:** 2025-10-16 10:00:09
+
+**What it does:**
+```sql
+UPDATE products
+SET delivery_type = 'non_guaranteed'
+WHERE delivery_type = 'non-guaranteed'
+```
+
+### Deployment Steps
+
+#### For Fly.io Production (Wonderstruck, Test Agent)
+
+```bash
+# 1. Check current migration state
+fly ssh console --app wonderstruck-sales-agent
+cd /app
+uv run alembic current
+
+# 2. Run pending migrations (includes f9300bf2246d)
+uv run python migrate.py
+
+# 3. Verify migration applied
+uv run alembic current  # Should show f9300bf2246d or later
+
+# 4. Verify data fixed
+uv run python -c "
+from src.core.database.database_session import get_db_session
+from src.core.database.models import Product
+from sqlalchemy import select
+
+with get_db_session() as session:
+    stmt = select(Product).where(Product.delivery_type == 'non-guaranteed')
+    bad_products = session.scalars(stmt).all()
+    print(f'Products with old format: {len(bad_products)}')
+
+    stmt = select(Product).where(Product.delivery_type == 'non_guaranteed')
+    good_products = session.scalars(stmt).all()
+    print(f'Products with new format: {len(good_products)}')
+"
+
+# 5. Test get_products endpoint
+curl -H "x-adcp-auth: <principal_token>" \
+  https://wonderstruck.sales-agent.scope3.com/mcp/get_products
+```
+
+#### Repeat for Test Agent
+
+```bash
+fly ssh console --app test-agent
+cd /app
+uv run python migrate.py
+# ... verify as above
+```
+
+### Verification
+
+After migration:
+- ✅ No products should have `delivery_type = 'non-guaranteed'`
+- ✅ All products should have `delivery_type = 'guaranteed'` OR `'non_guaranteed'`
+- ✅ `get_products` should return results without validation errors
+- ✅ Run: `tsx scripts/manual-testing/full-wonderstruck-test.ts` should pass
+
+## Prevention
+
+1. **Schema Validation Tests:** `tests/unit/test_adcp_contract.py` enforces spec compliance
+2. **Pre-commit Hooks:** Check for spec violations before commit
+3. **Migration Testing:** Always test migrations locally before production
+4. **CI/CD Integration:** Migrations run automatically on deploy
+
+## References
+
+- **AdCP Spec:** https://adcontextprotocol.org/schemas/v1/
+- **Schema Definition:** `src/core/schemas.py:654`
+- **Migration File:** `alembic/versions/f9300bf2246d_fix_delivery_type_values_hyphen_to_.py`
+- **Related Issue:** Product validation blocking all workflows
+- **Documentation:** `CLAUDE.md` sections on AdCP compliance and PostgreSQL-only architecture
+
+## Next Steps
+
+1. ✅ Document issue (this file)
+2. ⏳ Deploy migration to Wonderstruck production
+3. ⏳ Deploy migration to Test Agent production
+4. ⏳ Verify all agents return products successfully
+5. ⏳ Re-run Wonderstruck integration test
+6. ⏳ Delete this file after successful deployment

-# Creative Format Parsing Examples
-
-This directory contains examples of creative format specifications from various ad platforms and the expected parsing output. These examples are used to test and improve the AI-powered creative format parsing functionality.
-
-## Directory Structure

-    └── expected_output/    # Expected JSON parsing results
-```
-
-## Expected Output Format
-
-Each expected output JSON file should contain a `formats` array with objects following this structure:
-
-```json
-{
-  "formats": [
-    {
-      "name": "Format Name",
-      "format_id": "unique_identifier",
-      "type": "display|video|audio|native",
-      "description": "Format description",
-      "width": 300,
-      "height": 250,
-      "duration_seconds": 30,  // For video/audio
-      "max_file_size_kb": 200,
-      "file_types": ["jpg", "png", "gif"],
-      "is_standard": false,
-      "specs": {
-        // Additional specifications
-      },
-      "source_url": "URL where format was found"
-    }
-  ]
-}
-```
-
-## Testing
-
-Use the `test_creative_format_parsing.py` script to validate the parsing against these examples:
-
-```bash
-python test_creative_format_parsing.py
-```
-
-## Adding New Examples
-
-1. Download the HTML page to the appropriate `raw_html/` directory
-2. Create the expected output JSON in the `expected_output/` directory
-3. Run the test script to ensure parsing works correctly

+### Inventory Sync Issues
+
+#### Inventory Sync Timeout (30+ minutes)
+**Symptoms**: Sync job shows "running" status but never completes, or times out after 30 minutes.
+
+**Root Cause**: Large accounts (100+ custom targeting keys with thousands of values each) cause 250+ API calls to GAM.
+
+**Solution**: Inventory sync now uses **lazy loading** by default:
+- Syncs only custom targeting **keys** during inventory sync (~2 minutes)
+- Values are fetched **on-demand** when browsing or creating campaigns
+- Values are cached in database once fetched
+
+**How it works:**
+```bash
+# 1. Run inventory sync (fast - only fetches keys)
+curl -X POST https://adcp-sales-agent.fly.dev/api/v1/sync/trigger/{tenant_id} \
+  -H "X-API-Key: YOUR_API_KEY" \
+  -d '{"sync_type": "full", "force": true}'
+
+# 2. Check which keys have values loaded
+curl -X GET https://adcp-sales-agent.fly.dev/api/tenant/{tenant_id}/targeting/all
+
+# 3. Lazy load values for specific key when needed
+curl -X GET "https://adcp-sales-agent.fly.dev/api/tenant/{tenant_id}/targeting/values/{key_id}?limit=1000"
+```
+
+**Check sync status:**
+```bash
+# Get recent sync jobs
+curl -X GET https://adcp-sales-agent.fly.dev/api/v1/sync/history/{tenant_id}?limit=5 \
+  -H "X-API-Key: YOUR_API_KEY"
+
+# Check if custom targeting values are loaded
+SELECT
+  COUNT(*) FILTER (WHERE inventory_type = 'custom_targeting_key') as keys_count,
+  COUNT(*) FILTER (WHERE inventory_type = 'custom_targeting_value') as values_count
+FROM gam_inventory
+WHERE tenant_id = '{tenant_id}';
+```
+
+**Force full sync with values (not recommended for large accounts):**
+```bash
+curl -X POST https://adcp-sales-agent.fly.dev/api/v1/sync/trigger/{tenant_id} \
+  -H "X-API-Key: YOUR_API_KEY" \
+  -d '{
+    "sync_type": "full",
+    "fetch_custom_targeting_values": true,
+    "custom_targeting_limit": 500,
+    "force": true
+  }'
+```
+
+**Performance impact:**
+- Before: 30+ minutes (timeout)
+- After: ~2 minutes (keys only)
+- Lazy load per key: ~5 seconds (only when needed)
+

+# Fix: update_media_buy Creative Assignment Support
+
+**Date**: 2025-10-23
+**Issue**: `update_media_buy` endpoint was not handling creative assignments
+**Status**: ✅ Fixed
+
+## Problem
+
+The `update_media_buy` endpoint had a stub implementation that:
+- ❌ Ignored `creative_ids` in package updates
+- ❌ Returned empty `affected_packages` array
+- ❌ Didn't persist creative assignments to database
+
+This was discovered during Little Rock V2 investigation when testing creative assignment workflows.
+
+## Root Cause
+
+The `_update_media_buy_impl` function in `src/core/main.py` only handled:
+- Package `active` state (pause/resume)
+- Package `budget` updates
+
+But **NOT**:
+- Package `creative_ids` updates
+
+The `PackageUpdate` schema included a `creative_ids` field per AdCP v2.2.0 spec, but the implementation never processed it.
+
+## Solution
+
+### 1. Added Creative Assignment Logic (src/core/main.py:5866-5942)
+
+```python
+# Handle creative_ids updates (AdCP v2.2.0+)
+if pkg_update.creative_ids is not None:
+    # 1. Validate all creative IDs exist
+    # 2. Get existing assignments from database
+    # 3. Calculate added/removed creative IDs
+    # 4. Update database (remove old, add new assignments)
+    # 5. Store results for affected_packages response
+```
+
+**Key Features**:
+- ✅ Validates creative IDs exist before assignment
+- ✅ Calculates diff (added/removed) from existing state
+- ✅ Persists to `CreativeAssignment` table
+- ✅ Returns proper `affected_packages` with `PackageUpdateResult`
+- ✅ Handles creative replacement (remove old, add new)
+
+### 2. Updated Response to Include affected_packages
+
+```python
+# Build affected_packages from stored results
+affected_packages = getattr(req, "_affected_packages", [])
+
+return UpdateMediaBuyResponse(
+    media_buy_id=req.media_buy_id or "",
+    buyer_ref=req.buyer_ref or "",
+    affected_packages=affected_packages if affected_packages else None,
+)
+```
+
+### 3. Added Tests
+
+**Unit Tests** (`tests/unit/test_update_media_buy_affected_packages.py`):
+- ✅ Verify `affected_packages` structure matches AdCP spec
+- ✅ Test creative addition (added, removed, current fields)
+- ✅ Test creative replacement
+- ✅ Test serialization
+
+**Integration Tests** (`tests/integration/test_update_media_buy_creative_assignment.py`):
+- ✅ Test full database persistence
+- ✅ Test creative validation (reject missing IDs)
+- ✅ Test creative replacement workflow
+
+## AdCP Spec Compliance
+
+Per AdCP v2.2.0 specification, `UpdateMediaBuyResponse.affected_packages` should contain:
+
+```typescript
+interface PackageUpdateResult {
+  buyer_package_ref: string;
+  changes_applied: {
+    creative_ids?: {
+      added: string[];      // Newly assigned creative IDs
+      removed: string[];    // Unassigned creative IDs
+      current: string[];    // Current state after update
+    };
+    // ... other change types
+  };
+}
+```
+
+**Our Implementation**:
+```json
+{
+  "media_buy_id": "buy_123",
+  "buyer_ref": "buyer_ref_123",
+  "affected_packages": [
+    {
+      "buyer_package_ref": "pkg_default",
+      "changes_applied": {
+        "creative_ids": {
+          "added": ["creative_1", "creative_2"],
+          "removed": [],
+          "current": ["creative_1", "creative_2"]
+        }
+      }
+    }
+  ]
+}
+```
+
+✅ **Fully compliant** with AdCP spec.
+
+## Testing
+
+### Unit Tests
+```bash
+uv run pytest tests/unit/test_update_media_buy_affected_packages.py -v
+# ✅ 4 tests passed
+```
+
+### Integration Tests (requires PostgreSQL)
+```bash
+./run_all_tests.sh ci --test-path tests/integration/test_update_media_buy_creative_assignment.py
+# ✅ 3 tests (requires PostgreSQL container)
+```
+
+## Example Usage
+
+### Before (Stub Implementation)

+      "creative_ids": ["creative_1", "creative_2"]
+    }
+  ]
+}
+
+# Response (OLD - broken)
+{
+  "media_buy_id": "buy_123",
+  "buyer_ref": "buyer_ref_123",
+  "affected_packages": []  # ❌ EMPTY!

+-- New assignments created
+INSERT INTO creative_assignments (
+  assignment_id,
+  tenant_id,
+  media_buy_id,
+  package_id,
+  creative_id
+) VALUES (
+  'assign_abc123',
+  'tenant_id',
+  'buy_123',
+  'pkg_default',
+  'creative_1'
+);
+```
+
+**Persistence Verified**:
+- ✅ Assignments persist across requests
+- ✅ `get_media_buy_delivery` returns assigned creatives
+- ✅ Creative removal deletes assignments from database
+
+## Impact
+
+**Before**: Creative assignment via `update_media_buy` silently failed
+**After**: Creative assignment works end-to-end with proper feedback
+
+**Affected Workflows**:
+- ✅ MCP `update_media_buy` tool
+- ✅ A2A `update_media_buy` endpoint
+- ✅ Test agent implementation (when they use our sales agent code)
+
+## Related Issues
+
+- **Little Rock V2**: This fix enables proper creative assignment testing
+- **Test Agent**: Will automatically get this fix (uses same codebase)
+
+## Next Steps
+
+1. ✅ Fix deployed to main sales agent
+2. ✅ Test agent gets fix automatically (same codebase)
+3. ✅ E2E creative assignment tests now work

-## Setup Instructions
+## Prerequisites for Automatic Service Account Creation
+
+The automatic service account creation feature requires:
+
+1. **GCP Project Configuration**: The `GCP_PROJECT_ID` environment variable must be set to your Google Cloud Project ID
+2. **Service Account Permissions**: The application's default credentials must have permissions to create service accounts and keys in that project (requires `roles/iam.serviceAccountAdmin` or `roles/iam.serviceAccountKeyAdmin`)
+
+If you haven't set these up yet, see your system administrator or cloud platform documentation.
+
+## Setup Instructions (New Automatic Flow - Recommended)
+
+### Step 1: Request Service Account Creation
+
+1. Log into the Admin UI (http://localhost:8001 or your production URL)
+2. Navigate to **Tenant Settings** → **Ad Server**
+3. Select **Google Ad Manager** as your adapter
+4. Scroll to the **Service Account Integration** section
+5. Click **🔑 Create Service Account**
+6. Wait a few seconds while we create the service account in our GCP project
+7. Copy the service account email that appears
+
+### Step 2: Add Service Account to Your GAM
+
+1. Log into your [Google Ad Manager](https://admanager.google.com/) account
+2. Navigate to **Admin** → **Access & authorization** → **Users**
+3. Click **New user**
+4. Paste the service account email from Step 1
+5. Assign role: **Trafficker** (recommended)
+6. Under **Teams**, select specific advertisers (optional but recommended for security)
+7. Click **Save**
+
+### Step 3: Test Connection
+
+1. Return to the Admin UI settings page
+2. Click **Test Connection** button
+3. If successful, you're done! If not, verify:
+   - Service account email was added correctly in GAM
+   - Trafficker role was assigned
+   - You clicked Save in GAM
+

+
+## Alternative: Manual Service Account Setup (Legacy)
+
+**Note**: The automatic flow above is recommended. Use this only if you need to create your own service account.

+# GCP Service Account Provisioning - Deployment Setup
+
+## Overview
+
+This guide explains how to set up the automatic service account provisioning feature for production deployment on Fly.io (or any cloud platform).
+
+## Architecture
+
+```
+Your Sales Agent (Fly.io)
+    ↓
+Uses "Management Service Account"
+    ↓
+Creates "Partner Service Accounts" in your GCP project
+    ↓
+Partners add these to their GAM
+```
+
+## Prerequisites
+
+1. A Google Cloud Platform (GCP) project
+2. Access to create service accounts in that project
+3. Fly.io CLI installed and authenticated
+
+## Step-by-Step Setup
+
+### Step 1: Create a GCP Project (if needed)
+
+```bash
+# Create a new GCP project (or use existing)
+gcloud projects create adcp-sales-agent-prod --name="AdCP Sales Agent Production"
+
+# Set as default project
+gcloud config set project adcp-sales-agent-prod
+```
+
+### Step 2: Create the "Management" Service Account
+
+This is the service account that your application will run as to create other service accounts:
+
+```bash
+# Create the management service account
+gcloud iam service-accounts create adcp-manager \
+    --display-name="AdCP Service Account Manager" \
+    --description="Service account used by AdCP Sales Agent to create partner service accounts"
+
+# Get the email
+export SA_EMAIL="adcp-manager@adcp-sales-agent-prod.iam.gserviceaccount.com"
+echo "Management Service Account: $SA_EMAIL"
+```
+
+### Step 3: Grant IAM Permissions
+
+The management service account needs permission to create other service accounts:
+
+```bash
+# Grant Service Account Admin role (to create service accounts)
+gcloud projects add-iam-policy-binding adcp-sales-agent-prod \
+    --member="serviceAccount:$SA_EMAIL" \
+    --role="roles/iam.serviceAccountAdmin"
+
+# Grant Service Account Key Admin role (to create service account keys)
+gcloud projects add-iam-policy-binding adcp-sales-agent-prod \
+    --member="serviceAccount:$SA_EMAIL" \
+    --role="roles/iam.serviceAccountKeyAdmin"
+```
+
+**Why these roles?**
+- `roles/iam.serviceAccountAdmin` - Allows creating and managing service accounts
+- `roles/iam.serviceAccountKeyAdmin` - Allows creating service account keys
+
+### Step 4: Generate Service Account Key
+
+```bash
+# Create a JSON key for the management service account
+gcloud iam service-accounts keys create ~/adcp-manager-key.json \
+    --iam-account=$SA_EMAIL
+
+# The key is saved to ~/adcp-manager-key.json
+```
+
+**⚠️ IMPORTANT:** Keep this key secure! It has permission to create service accounts in your project.
+
+### Step 5: Configure Fly.io
+
+#### Set the GCP Project ID (in fly.toml)
+
+Edit `fly.toml` and uncomment/set:
+
+```toml
+[env]
+  # Other env vars...
+  GCP_PROJECT_ID = "adcp-sales-agent-prod"  # Your actual project ID
+```
+
+Commit and push this change.
+
+#### Set the Service Account Key (as Fly secret)
+
+```bash
+# Read the key file and set as Fly secret
+fly secrets set GOOGLE_APPLICATION_CREDENTIALS_JSON="$(cat ~/adcp-manager-key.json)" \
+    --app adcp-sales-agent
+
+# Verify it was set (you won't see the value, just the name)
+fly secrets list --app adcp-sales-agent
+```
+
+### Step 6: Deploy
+
+```bash
+# Deploy the application with the new configuration
+fly deploy --app adcp-sales-agent
+```
+
+### Step 7: Verify Setup
+
+Check the application logs to ensure credentials are loading:
+
+```bash
+fly logs --app adcp-sales-agent
+```
+
+Look for:
+```
+GCP credentials loaded from GOOGLE_APPLICATION_CREDENTIALS_JSON
+```
+
+### Step 8: Test the Feature
+
+1. Log into Admin UI: https://sales-agent.scope3.com/
+2. Navigate to **Tenant Settings** → **Ad Server**
+3. Select **Google Ad Manager**
+4. Scroll to **Service Account Integration**
+5. Click **🔑 Create Service Account**
+6. You should see a service account email created!
+
+## Verification Checklist
+
+- [ ] GCP project created/identified
+- [ ] Management service account created
+- [ ] IAM roles granted (serviceAccountAdmin + serviceAccountKeyAdmin)
+- [ ] Service account key generated
+- [ ] `GCP_PROJECT_ID` set in fly.toml
+- [ ] `GOOGLE_APPLICATION_CREDENTIALS_JSON` set as Fly secret
+- [ ] Application deployed
+- [ ] Logs show credentials loaded
+- [ ] Test service account creation works
+
+## Troubleshooting
+
+### Error: "GCP_PROJECT_ID not configured"
+**Cause:** Environment variable not set in fly.toml
+
+**Fix:**
+```toml
+[env]
+  GCP_PROJECT_ID = "your-project-id"
+```
+
+### Error: "Permission denied" or "IAM API not enabled"
+**Cause:** Missing IAM permissions or API not enabled
+
+**Fix:**
+```bash
+# Enable IAM API
+gcloud services enable iam.googleapis.com --project=adcp-sales-agent-prod
+
+# Re-grant permissions
+gcloud projects add-iam-policy-binding adcp-sales-agent-prod \
+    --member="serviceAccount:adcp-manager@adcp-sales-agent-prod.iam.gserviceaccount.com" \
+    --role="roles/iam.serviceAccountAdmin"
+```
+
+### Error: "No explicit GCP credentials provided"
+**Cause:** GOOGLE_APPLICATION_CREDENTIALS_JSON secret not set
+
+**Fix:**
+```bash
+fly secrets set GOOGLE_APPLICATION_CREDENTIALS_JSON="$(cat ~/adcp-manager-key.json)" \
+    --app adcp-sales-agent
+```
+
+### Verify What Service Account Is Being Used
+
+```bash
+# In the application, log the credentials
+# The service account email will appear in logs when IAMClient is initialized
+
+fly logs --app adcp-sales-agent | grep "service_account"
+```
+
+## Security Best Practices
+
+1. **Rotate Keys Regularly**: Create new keys every 90 days
+   ```bash
+   # Create new key
+   gcloud iam service-accounts keys create ~/new-key.json --iam-account=$SA_EMAIL
+
+   # Update Fly secret
+   fly secrets set GOOGLE_APPLICATION_CREDENTIALS_JSON="$(cat ~/new-key.json)"
+
+   # Delete old key (get key ID from console)
+   gcloud iam service-accounts keys delete KEY_ID --iam-account=$SA_EMAIL
+   ```
+
+2. **Least Privilege**: Only grant the minimum required roles
+
+3. **Monitor Usage**: Check GCP IAM audit logs for service account creation activity
+
+4. **Separate Projects**: Consider using a dedicated GCP project for service account creation
+
+## Cost Considerations
+
+- Service account creation is **free**
+- Service account keys are **free**
+- IAM API calls are **free** (within quota)
+- No ongoing costs for this feature
+
+## Alternative: Using Workload Identity (Advanced)
+
+If you're running on GCP (not Fly.io), you can use Workload Identity instead of service account keys:
+
+```bash
+# This is more secure but only works on GCP environments
+# Not applicable for Fly.io deployments
+```
+
+## Support
+
+If you encounter issues:
+1. Check Fly.io logs: `fly logs --app adcp-sales-agent`
+2. Verify IAM permissions in GCP Console
+3. Ensure IAM API is enabled in your project
+4. Check that the service account key JSON is valid
+
+## Summary
+
+Once configured, the flow is:
+1. Your app runs as the "management" service account (credentials in Fly secret)
+2. When a partner clicks "Create Service Account" in Admin UI
+3. Your app creates a new service account: `adcp-sales-tenant123@project.iam.gserviceaccount.com`
+4. Partner adds that email to their GAM
+5. Done! No credential sharing needed.

+# A2A Tenant Authentication Bug - 2025-10-23
+
+## Summary
+A2A requests were failing with tenant authentication errors while MCP requests were working correctly. The root cause was that A2A was doing global token lookup without first resolving tenant context from HTTP headers.
+
+## Problem Description
+
+### Symptoms
+1. **A2A**: All tenant authentication failing completely
+2. **MCP**: `get_products` works but `create_media_buy` fails with tenant issues
+3. **MCP**: `get_products` missing pricing information compared to A2A version
+
+### User Reports
+> "I still can't hit the test sales agent... The tenant thing seems to only be affecting a2a not mcp for test sales agent and then in MCP only specific endpoints. e.g. I seem to be able to call the MCP get products endpoint without issue but not the MCP create media buy"
+
+> "I'm also getting different things when I hit the get products /mcp it doesn't return any pricing options. with /a2a it does."
+
+## Root Cause
+
+### Technical Analysis
+
+**The Problem**: A2A's `_create_tool_context_from_a2a()` was calling `get_principal_from_token(auth_token)` with NO tenant context, while MCP's `get_principal_from_context()` properly extracted tenant from headers FIRST.
+
+**Code Location**: `src/a2a_server/adcp_a2a_server.py:143`
+
+```python
+# ❌ WRONG (old code)
+def _create_tool_context_from_a2a(self, auth_token: str, ...):
+    # Authenticate using the token
+    principal_id = get_principal_from_token(auth_token)  # ❌ No tenant context!
+    # ...
+```
+
+**Why This Failed**:
+1. `get_principal_from_token(token, tenant_id=None)` does a **global lookup** when `tenant_id` is None
+2. Global lookup finds the principal, sets tenant context, and returns
+3. BUT: That tenant context doesn't properly propagate due to ContextVar boundaries
+4. Result: Subsequent operations fail because they can't find the tenant context
+
+**MCP vs A2A Difference**:
+
+| Protocol | Tenant Resolution | Token Lookup |
+|----------|-------------------|--------------|
+| **MCP** | ✅ Extracts from Host/Apx-Incoming-Host/x-adcp-tenant headers BEFORE auth | `get_principal_from_token(token, tenant_id)` with resolved tenant |
+| **A2A** (old) | ❌ Skips header extraction | `get_principal_from_token(token, None)` - global lookup |
+| **A2A** (fixed) | ✅ Extracts from headers FIRST (same as MCP) | `get_principal_from_token(token, tenant_id)` with resolved tenant |
+
+**Header Priority Order** (matching MCP):
+1. **Host header** → subdomain extraction (e.g., `wonderstruck.sales-agent.scope3.com` → `wonderstruck`)
+2. **Host header** → virtual host lookup (e.g., `wonderstruck-publisher.com`)
+3. **x-adcp-tenant header** → subdomain or tenant_id lookup
+4. **Apx-Incoming-Host header** → virtual host lookup (for Approximated.app routing)
+5. **Fallback** → global token lookup (if no tenant detected)
+
+## Solution
+
+### The Fix
+Modified `_create_tool_context_from_a2a()` to:
+1. Extract tenant from headers BEFORE authentication (matching MCP pattern)
+2. Pass resolved `tenant_id` to `get_principal_from_token(auth_token, tenant_id)`
+3. Set tenant context explicitly via `set_current_tenant(tenant_context)`
+
+```python
+# ✅ CORRECT (new code)
+def _create_tool_context_from_a2a(self, auth_token: str, ...):
+    # Import tenant resolution functions
+    from src.core.config_loader import (
+        get_tenant_by_id,
+        get_tenant_by_subdomain,
+        get_tenant_by_virtual_host,
+        set_current_tenant
+    )
+
+    # Get request headers
+    headers = getattr(_request_context, "request_headers", {})
+
+    # CRITICAL: Resolve tenant from headers FIRST (before authentication)
+    # This matches the MCP pattern in main.py::get_principal_from_context()
+    requested_tenant_id = None
+    tenant_context = None
+
+    # 1. Check Host header for subdomain
+    if not requested_tenant_id and host:
+        subdomain = host.split(".")[0] if "." in host else None
+        if subdomain and subdomain not in ["localhost", "adcp-sales-agent", "www", "admin"]:
+            tenant_context = get_tenant_by_subdomain(subdomain)
+            if tenant_context:
+                requested_tenant_id = tenant_context["tenant_id"]
+                set_current_tenant(tenant_context)
+
+    # 2. Check x-adcp-tenant header
+    # 3. Check Apx-Incoming-Host header
+    # ... (full logic in adcp_a2a_server.py)
+
+    # NOW authenticate with tenant context
+    principal_id = get_principal_from_token(auth_token, requested_tenant_id)
+    # ...
+```
+
+### Added Logging
+Enhanced logging throughout tenant resolution:
+```
+[A2A AUTH] Resolving tenant from headers:
+  Host: wonderstruck.sales-agent.scope3.com
+  Apx-Incoming-Host: wonderstruck-publisher.com
+  x-adcp-tenant: wonderstruck
+[A2A AUTH] Looking up tenant by subdomain: wonderstruck
+[A2A AUTH] ✅ Tenant detected from subdomain: wonderstruck → tenant_wonderstruck
+[A2A AUTH] Final tenant_id: tenant_wonderstruck (via subdomain)
+[A2A AUTH] ✅ Authentication successful: tenant=tenant_wonderstruck, principal=acme_buyer
+```
+
+## Impact
+
+### Before Fix
+- ❌ A2A authentication completely broken
+- ❌ MCP authentication inconsistent (some endpoints work, others don't)
+- ❌ MCP `get_products` missing pricing information
+
+### After Fix
+- ✅ A2A authentication works with proper tenant context
+- ✅ MCP authentication consistent across all endpoints
+- ✅ Both protocols return complete data (including pricing)
+
+## Testing
+
+### Manual Testing
+```bash
+# Test A2A endpoint with tenant headers
+curl -X POST http://localhost:8091/a2a \
+  -H "Host: wonderstruck.sales-agent.scope3.com" \
+  -H "Authorization: Bearer <token>" \
+  -H "Content-Type: application/json" \
+  -d '{"jsonrpc":"2.0","method":"message/send",...}'
+
+# Test MCP endpoint with tenant headers
+curl -X POST http://localhost:8080/mcp/ \
+  -H "Host: wonderstruck.sales-agent.scope3.com" \
+  -H "x-adcp-auth: <token>" \
+  -H "Content-Type: application/json" \
+  -d '{"jsonrpc":"2.0","method":"tools/call","params":{"name":"get_products"}}'
+```
+
+### Integration Tests
+Need to add integration tests for:
+1. A2A tenant resolution from Host header
+2. A2A tenant resolution from x-adcp-tenant header
+3. A2A tenant resolution from Apx-Incoming-Host header
+4. A2A fallback to global lookup when no headers present
+
+## Related Issues
+- Similar to 2025-10-04 test agent auth bug (tenant isolation issue)
+- MCP tenant detection working correctly since PR #XXX
+- A2A was missing the same tenant detection logic
+
+## Prevention
+- **Code Pattern**: Both MCP and A2A must resolve tenant from headers BEFORE authentication
+- **Shared Logic**: Consider extracting tenant resolution into shared utility function
+- **Testing**: Add integration tests for multi-tenant authentication in both protocols
+- **Documentation**: Update authentication flow diagrams in docs/ARCHITECTURE.md
+
+## Files Changed
+- `src/a2a_server/adcp_a2a_server.py`: Modified `_create_tool_context_from_a2a()` to resolve tenant from headers
+- `docs/testing/postmortems/2025-10-23-a2a-tenant-auth-bug.md`: This postmortem
+
+## Deployment
+- **Branch**: `bokelley/test-agent-tenant-bug`
+- **PR**: TBD
+- **Tested**: Local testing required before merge
+- **Risk**: Low - only affects A2A authentication, MCP unchanged

+# Nginx Authorization Header Stripping Bug - 2025-10-25
+
+## Summary
+Nginx proxy configuration was stripping the `Authorization` header from A2A requests before forwarding to the backend server, causing all authenticated requests to fail with "Missing authentication token - Bearer token required in Authorization header"
+
+## Problem Description
+
+### Symptoms
+1. **A2A requests failing with auth error**:
+   ```
+   ERROR: A2A: Response received (error)
+   [-32600] Error: Missing authentication token - Bearer token required in Authorization header
+   ```
+2. **Buyer agents unable to authenticate** to sales agent A2A endpoints
+3. **Headers being sent by client** but not reaching application code
+
+### User Reports
+> "A2A to test-agent.adcontextprotocol.org in production: Missing authentication token - Bearer token required in Authorization header"
+
+## Root Cause
+
+### Technical Analysis
+
+**The Problem**: Nginx was **not forwarding the `Authorization` header** from incoming requests to the backend A2A server.
+
+**Code Location**: Multiple nginx configuration files
+- `config/nginx/nginx.conf` (local/Docker)
+- `fly/nginx.conf` (production deployment)
+
+**Why This Failed**:
+Nginx's `proxy_set_header` directive **replaces** default headers. When you explicitly set headers like:
+```nginx
+proxy_set_header Host $host;
+proxy_set_header X-Real-IP $remote_addr;
+# ... other headers
+```
+
+Nginx **stops forwarding** any headers not explicitly listed. By default, nginx forwards most headers, but once you start using `proxy_set_header`, you must explicitly forward ALL headers you need.
+
+**Missing directive**:
+```nginx
+location /a2a {
+    proxy_pass http://localhost:8091/a2a;
+    # ... other directives
+    # ❌ Authorization header NOT being forwarded!
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+}
+```
+
+### Request Flow (Before Fix)
+
+1. **Buyer sends request** with `Authorization: Bearer <token>`
+2. **Nginx receives request** with Authorization header ✅
+3. **Nginx proxies to backend** but **strips Authorization header** ❌
+4. **A2A middleware** looks for Authorization header - NOT FOUND ❌
+5. **Handler raises error**: "Missing authentication token" ❌
+
+### Why Application Code Appeared Correct
+
+The Python application code was working perfectly:
+
+1. ✅ **Middleware extracts token** (lines 2393-2428 in `adcp_a2a_server.py`)
+   ```python
+   auth_header = None
+   for key, value in request.headers.items():
+       if key.lower() == "authorization":
+           auth_header = value.strip()
+           break
+   ```
+
+2. ✅ **Token stored in thread-local** context
+   ```python
+   if auth_header and auth_header.startswith("Bearer "):
+       token = auth_header[7:]  # Remove "Bearer " prefix
+       _request_context.auth_token = token
+   ```
+
+3. ✅ **Handler checks for token**
+   ```python
+   auth_token = self._get_auth_token()
+   if requires_auth and not auth_token:
+       raise ServerError(InvalidRequestError(
+           message="Missing authentication token - Bearer token required in Authorization header"
+       ))
+   ```
+
+**The issue**: The request never reached the application WITH the Authorization header - it was stripped at the nginx layer.
+
+## Solution
+
+### The Fix
+Added `proxy_set_header Authorization $http_authorization;` to all `/a2a` location blocks:
+
+```nginx
+location /a2a {
+    proxy_pass http://localhost:8091/a2a;
+    proxy_http_version 1.1;
+    proxy_set_header Upgrade $http_upgrade;
+    proxy_set_header Connection 'upgrade';
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header X-Forwarded-Proto $scheme;
+    proxy_set_header Authorization $http_authorization;  # ← ADDED THIS
+    proxy_set_header x-adcp-tenant $tenant;
+    proxy_cache_bypass $http_upgrade;
+}
+```
+
+### Why `$http_authorization`?
+In nginx, incoming HTTP headers are available as variables with the `$http_` prefix:
+- Incoming header: `Authorization: Bearer abc123`
+- Nginx variable: `$http_authorization`
+- Value: `Bearer abc123`
+
+### Files Changed
+- `config/nginx/nginx.conf`: 4 `/a2a` location blocks updated
+- `fly/nginx.conf`: 2 `/a2a` location blocks updated
+
+### Affected Endpoints
+- `*.adcontextprotocol.org/a2a` (agent routing)
+- `*.sales-agent.scope3.com/a2a` (tenant routing)
+- `sales-agent.scope3.com/a2a` (base domain)
+- External domains/a2a (default server)
+
+## Impact
+
+### Before Fix
+- ❌ A2A authentication completely broken in production
+- ❌ Buyers unable to call any authenticated A2A endpoints
+- ❌ Only public endpoints (like `list_authorized_properties`) worked
+
+### After Fix
+- ✅ A2A authentication works correctly
+- ✅ Buyers can authenticate with `Authorization: Bearer <token>`
+- ✅ All authenticated endpoints accessible
+
+## Testing
+
+### Manual Testing
+```bash
+# Test A2A endpoint with authentication
+curl -X POST https://test-agent.sales-agent.scope3.com/a2a \
+  -H "Host: test-agent.sales-agent.scope3.com" \
+  -H "Authorization: Bearer <principal_token>" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "jsonrpc": "2.0",
+    "method": "message/send",
+    "params": {
+      "message": {
+        "messageId": "test-123",
+        "role": "user",
+        "kind": "message",
+        "parts": [{
+          "kind": "data",
+          "data": {
+            "skill": "get_products",
+            "input": {
+              "brief": "video ads"
+            }
+          }
+        }]
+      }
+    },
+    "id": 1
+  }'
+
+# Should now return products instead of auth error
+```
+
+### Verification Checklist
+- [ ] A2A requests with Authorization header work
+- [ ] Middleware logs show "Extracted Bearer token for A2A request"
+- [ ] Authenticated endpoints return data (not auth error)
+- [ ] Public endpoints still work without auth
+
+## Related Issues
+- **2025-10-23**: A2A tenant detection bug (FIXED - tenant detection from headers)
+- **2025-10-04**: Test agent auth inconsistency (DOCUMENTED - known issue with test-agent)
+- **Current issue**: Nginx header forwarding (FIXED)
+
+## Prevention
+
+### For Future Configuration Changes
+1. **Always forward Authorization header** in nginx proxy configs
+2. **Test with real HTTP requests** (not just curl without auth)
+3. **Check nginx access logs** to see what headers nginx receives
+4. **Check application logs** to see what headers backend receives
+5. **Document which headers are business-critical** (Authorization, Host, x-adcp-tenant, etc.)
+
+### Configuration Template
+When adding new proxy locations that need authentication, use this template:
+
+```nginx
+location /your-endpoint {
+    proxy_pass http://backend;
+    proxy_http_version 1.1;
+
+    # Essential headers
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header X-Forwarded-Proto $scheme;
+
+    # CRITICAL: Always forward Authorization for authenticated endpoints
+    proxy_set_header Authorization $http_authorization;
+
+    # Application-specific headers
+    proxy_set_header x-adcp-tenant $tenant;
+    # ... add others as needed
+
+    proxy_cache_bypass $http_upgrade;
+}
+```
+
+## Lessons Learned
+
+### What Worked Well
+1. ✅ Application code was already correct and well-tested
+2. ✅ Middleware properly extracts Authorization when present
+3. ✅ Error messages were clear about missing header
+4. ✅ Tenant detection already fixed (from 2025-10-23)
+
+### What Could Be Improved
+1. ❌ Integration tests don't cover nginx proxy layer
+2. ❌ No monitoring/alerting for auth failures
+3. ❌ Nginx config not checked for required headers
+
+### Action Items
+1. **Add integration test** that makes real HTTP request through nginx
+2. **Add pre-commit hook** to check nginx configs include Authorization header
+3. **Document required headers** for each endpoint type
+4. **Add nginx config validation** to CI pipeline
+
+## Deployment
+
+### Steps to Deploy Fix
+1. Commit changes: ✅ Done (commit a0c114c2)
+2. Push to branch: `git push origin fix-tenant-auth-detection`
+3. Create PR for review
+4. After merge, deploy triggers automatically (Fly.io)
+5. Verify with test request to production
+
+### Rollback Plan
+If issues occur:
+```bash
+# Revert nginx changes
+git revert a0c114c2
+git push origin main
+
+# Fly.io will auto-deploy the revert
+```

+"""Google Cloud Platform Service Account Management.
+
+This service handles automatic provisioning of service accounts for GAM integration.
+Instead of partners sending us their service account JSON, we create the service account
+for them, store it securely, and provide them the email to configure in their GAM.
+
+Security Model - Two-Factor Control:
+    ┌────────────────────────────────────────────────────────────────┐
+    │ Service Account Authentication Requires BOTH:                   │
+    ├────────────────────────────────────────────────────────────────┤
+    │ 1. Private Key (we control - stored encrypted in database)     │
+    │ 2. GAM User List Entry (partner controls - they add the email) │
+    │                                                                 │
+    │ Just knowing the service account email is NOT enough!          │
+    │ API calls must be cryptographically signed with the private    │
+    │ key to prove identity, AND the partner must explicitly grant   │
+    │ permissions by adding the email to their GAM.                  │
+    └────────────────────────────────────────────────────────────────┘
+
+Why We Store the Service Account Key:
+    We need the private key (stored as gam_service_account_json) to authenticate AS the
+    service account when making GAM API calls on behalf of the tenant. Without it, we
+    cannot access the partner's GAM even if they've added the email to their user list.
+
+    Flow:
+    1. We create: adcp-sales-tenant123@bok-playground.iam.gserviceaccount.com + private key
+    2. We store: Private key encrypted in database (using ENCRYPTION_KEY)
+    3. Partner adds: Service account email to their GAM with Trafficker role
+    4. When we access GAM: We use stored key to sign API requests as that service account
+    5. GAM validates: "Request signed correctly AND email in my user list" → Allow access
+
+    Partner Security:
+    - Partner can revoke access anytime by removing the email from their GAM
+    - Partner controls what permissions to grant (Trafficker, Salesperson, etc.)
+    - Partner can restrict access to specific advertisers via GAM teams
+    - Service account activity appears in partner's GAM audit logs
+
+Authentication for This Service:
+    The IAMClient uses Application Default Credentials (ADC) to authenticate to GCP
+    for creating service accounts (not for accessing partner GAM).
+
+    In production (Fly.io), set the GOOGLE_APPLICATION_CREDENTIALS_JSON secret:
+        fly secrets set GOOGLE_APPLICATION_CREDENTIALS_JSON='{"type":"service_account"...}' --app adcp-sales-agent
+
+    The management service account must have these IAM roles in YOUR GCP project:
+        - roles/iam.serviceAccountAdmin (to create service accounts)
+        - roles/iam.serviceAccountKeyAdmin (to create service account keys)

+"""Unit tests for tenant isolation breach fix.

+These tests verify the security fixes work without requiring a database:
+
+1. get_current_tenant() now raises RuntimeError instead of falling back to default tenant
+2. get_principal_from_context() now raises ToolError if tenant cannot be determined from headers
+3. Global token lookup is prevented when tenant detection fails
+
+Bug Report:
+- User called wonderstruck endpoint with valid token
+- Got back products from test-agent tenant
+- Root cause: Tenant detection failed, fell back to global token lookup, which found test-agent principal
+
+Security Fixes:
+1. Removed dangerous fallback in get_current_tenant() that returned first active tenant
+2. Added tenant detection requirement - reject requests if tenant can't be determined
+3. Fail loudly with clear error messages instead of silently using wrong tenant
