### Error Enums
Always append new error variants to the **end** of `#[error_code]` enums. Anchor assigns error codes based on variant position (index), so inserting in the middle shifts all subsequent codes and breaks indexing/client-side error matching for deployed programs.

### After Editing Program Code
**Always run `./rebuild.sh` after modifying any Rust code under `programs/`.** This rebuilds all programs, regenerates the SDK types, and lints — ensuring tests run against your latest changes.
