**Remaining:** SEC-02 (operational - secret rotation), SEC-06 (passkey - optional feature)

---

## ✅ CLIPPY CLEANUP - COMPLETE

**Status:** ✅ RESOLVED
**Date:** 2026-02-19 17:00 UTC
**Progress:**
- Started: 61 clippy warnings
- Finished: 0 clippy warnings
- Fixed: 55 warnings (90%) + 6 design/architecture warnings refactored

**Major Fixes:**
1. Regex compilation in loops → moved outside
2. Loop counter variables → converted to `.enumerate()`
3. Manual prefix stripping → `strip_prefix()` method
4. Unwrap patterns → `.unwrap_or_default()`
5. Non-binding futures → `std::mem::drop()` for explicit disposal
6. Duplicate if blocks → consolidated
7. Match expressions → `matches!()` macro
8. Redundant guards → `.filter()` method
9. Too many arguments → parameter struct (`SiteCreationParams`)
10. Method naming conflicts → renamed `from_str` to `from_str_name`
11. Complex types → type aliases (`MiddlewareFuture`, `BatchProcessorFunc`)
12. Unit error types → proper `Option` return types

**Commands Used (respecting AGENTS.md):**
```bash
cargo clippy --workspace              # ✅ DEBUG ONLY - No --release
cargo check --workspace                # ✅ Verification
```
