✅ 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):

cargo clippy --workspace              # ✅ DEBUG ONLY - No --release
cargo check --workspace                # ✅ Verification
