 ### Go Version
-- **Required**: Go 1.25.9
+- **Required**: Go 1.26
 - **Tool**: Use [gvm](https://github.com/andrewkroh/gvm) for version management
 - **CRITICAL**: Always run this before ANY Go command:

   # For Apple Silicon (M1/M2/M3)
-  eval "$(gvm 1.25.9 --arch=arm64)"

 1. **Read the error message carefully** - it usually tells you exactly what's wrong
 2. **Check if it's a lint issue** - run `make pre-commit` first

 4. **Check Docker** - some tests require Docker daemon running
 
 ## Common Pitfalls to Avoid
 
 ### Code Issues
 - ❌ Using interface types as return values
-- ❌ Forgetting to run `eval "$(gvm 1.25.9 --arch=arm64)"`
+- ❌ Forgetting to run `eval "$(gvm 1.26 --arch=arm64)"`
 - ❌ Not handling errors from built-in options
 - ❌ Using module-specific container names (`PostgresContainer`)
 - ❌ Calling `.Customize()` method instead of direct function call
