# Async Functions Without Await - TODO

Generated: 2026-01-04

## Summary

There are **277 async functions** that don't use `.await` internally. These add unnecessary overhead by creating state machines for synchronous code.

## Why Not Fixed Now

Removing `async` from these functions requires:
1. Removing `.await` from all call sites
2. Some implement `async_trait` which mandates async signatures
3. Changes cascade across multiple files

## Priority

Medium - Performance improvement but not critical for correctness.

## How to Fix

1. For standalone async functions: Remove `async` keyword and remove `.await` from call sites
2. For trait implementations: Check if trait can be made sync, or leave as-is
3. Run `cargo check` after each change to catch cascading errors
