+## Email Router Architecture Decision (2025-05-28)
+
+### Single Router Class
+- **Important**: We will have only ONE router class, not two
+- The existing `DomainRouter` will be evolved into `EmailRouter`
+- This avoids confusion and redundancy
+- Use `git mv` to rename and preserve git history
+- Extend it to support the new match/action pattern inspired by SmartProxy
+- Maintain backward compatibility for legacy domain-based rules
+
+### Benefits of Single Router
+- Clear, single source of truth for routing logic
+- No confusion about which router to use
+- Preserved git history and gradual migration path
+- Supports all match criteria (not just domains)

+## Configuration System Cleanup (2025-05-27) - COMPLETED
+
+### Overview
+The `ts/config/` directory cleanup has been completed. Removed ~500+ lines of unused legacy configuration code.
+
+### Changes Made
+✅ **Removed Files:**
+- `base.config.ts` - All unused base interfaces
+- `platform.config.ts` - Completely unused platform config
+- `email.config.ts` - Deprecated email configuration
+- `email.port.mapping.ts` - Unused port mapping utilities
+- `schemas.ts` - Removed all schemas except SMS
+- `sms.config.ts` - Moved to SMS module
+
+✅ **SMS Configuration Moved:**
+- Created `ts/sms/config/sms.config.ts` - ISmsConfig interface
+- Created `ts/sms/config/sms.schema.ts` - Validation schema
+- Updated SmsService to import from new location
+
+✅ **Kept:**
+- `validator.ts` - Generic validation utility (might move to utils later)
+- `index.ts` - Now only exports ConfigValidator
+
+### Result
+- Config directory now contains only 2 files (validator.ts, index.ts)
+- SMS configuration is self-contained in SMS module
+- All deprecated email configuration removed
+- Build passes successfully
