+
+## 📦 Product-Specific Secret Patterns
+
+### MindLyst Product (12 secrets) ✅
+**Prefix:** `mindlyst-*`  
+**Status:** Fully populated  
+**Secrets:**
+- Cosmos DB (endpoint, key, database)
+- Blob Storage (connection string)
+- Azure OpenAI (endpoint, key, deployment, api-version)
+- Azure Speech (key, region)
+- Notification Hub (connection string)
+- Application Insights (connection string)
+
+### MyWisprAI Product (7 secrets) ⚠️
+**Prefix:** `wispr-*`  
+**Status:** Partially populated  
+**Secrets:**
+- Azure OpenAI (endpoint, key, deployment)
+- Azure Speech (key, region)
+
+**Missing:**
+- Cosmos DB secrets
+- Blob Storage secrets
+- Stripe secrets
+- JWT secret
+
+### LysnrAI Product (0 secrets) ❌
+**Prefix:** `lysnr-*`  
+**Status:** Completely missing  
+**Expected:** 13 secrets  
+**Actual:** 0 secrets
+
+**This is the primary gap!** The platform services are designed for LysnrAI but have zero secrets in Key Vault.
+
+---
+
+## 🔧 Remediation Plan
+
+### Step 1: Seed LysnrAI Secrets (Immediate)
+
+Use the provided script with populated .env file:
+
+```bash
+# 1. Create .env with all secrets
+cp .env.example .env
+# Edit .env and fill in real values
+
+# 2. Run the seeding script
+./scripts/seed-keyvault.sh
+
+# 3. Verify secrets were created
+az keyvault secret list --vault-name kv-mywisprai --output table
+```
+
+The script will create all 13 `lysnr-*` secrets automatically.
+
+### Step 2: Update Services to Use Key Vault
+
+Add to each service's startup (already implemented in code):
+
+```typescript
+import { resolveKeyVaultSecrets, LYSNR_SECRETS } from '@bytelyst/config';
+
+// Before loading config
+await resolveKeyVaultSecrets(Object.values(LYSNR_SECRETS));
+
+// Then load config (will use KV values)
+const config = loadConfig();
+```
+
+### Step 3: Test Key Vault Integration
+
+```bash
+# Set Key Vault URL
+export AZURE_KEYVAULT_URL=https://kv-mywisprai.vault.azure.net
+
+# Remove local .env secrets to test KV
+mv .env .env.backup
+
+# Start service (should fetch from KV)
+pnpm --filter @lysnrai/platform-service dev
+
+# Check logs for KV resolution
+# Should see: "[keyvault] Resolving 13 secrets from Key Vault"
+```
+
+### Step 4: Verify Each Service
+
+| Service | Port | Test Endpoint | Expected Status |
+|---------|------|---------------|-----------------|
+| platform-service | 4003 | GET /health | 200 OK |
+| extraction-service | 4005 | GET /health | 200 OK |
+
+### Step 5: Production Checklist
+
+- [ ] Seed all `lysnr-*` secrets to Key Vault
+- [ ] Add Stripe secrets (test keys first, then prod)
+- [ ] Add Gemini API key
+- [ ] Configure managed identity for services
+- [ ] Remove connection strings from code/env files
+- [ ] Enable Key Vault audit logging
+- [ ] Set up secret rotation schedule
+- [ ] Document secret access patterns
+
+---
+
+## 🔄 Secret Rotation Strategy
+
+### Recommended Rotation Schedule:
+
+| Secret Type | Rotation Frequency | Method |
+|-------------|-------------------|--------|
+| Cosmos DB keys | Quarterly | Azure Portal → rotate keys → update KV |
+| JWT secret | Quarterly | Generate new → update KV → rolling deploy |
+| Stripe keys | Annually or on breach | Stripe Dashboard → update KV |
+| API keys (Gemini, OpenAI) | Annually or on breach | Provider portal → update KV |
+| Blob storage keys | Quarterly | Azure Portal → rotate keys → update KV |
+
+### Rotation Procedure:
+1. Generate new secret in Azure Portal / provider
+2. Update Key Vault with new value
+3. Services auto-fetch new secret on next restart (or use Key Vault rotation event)
+4. Monitor for errors
+5. Revoke old secret after 24h grace period

+## 🚀 Quick Fix Commands
+
+### Get Azure Resource Keys (for seeding):
+
+```bash
+# Cosmos DB
+az cosmosdb keys list --name cosmos-mywisprai --resource-group rg-mywisprai --type keys
+
+# Blob Storage
+az storage account keys list --account-name bytelystblobs --resource-group rg-mywisprai
+
+# OpenAI
+az cognitiveservices account keys list --name mywisprai-openai-sweden --resource-group rg-mywisprai
+
+# Speech Services
+az cognitiveservices account keys list --name mywisprai-speech --resource-group rg-mywisprai
+```
+
+### Manually Add a Secret:
+
+```bash
+az keyvault secret set \
+  --vault-name kv-mywisprai \
+  --name lysnr-cosmos-key \
+  --value "your-actual-cosmos-key-here"
+```
+
+### Verify Secret Resolution in Code:
+
+```bash
+# Check if KV is being used
+export AZURE_KEYVAULT_URL=https://kv-mywisprai.vault.azure.net
+node -e "process.env.AZURE_KEYVAULT_URL && console.log('✅ KV enabled') || console.log('❌ KV disabled')"
+```
