## Recent Fixes

### PATH Configuration Fix (2026-01-18)
Fixed an issue where the `go` command was not found in the container's PATH during runtime:
- **Problem**: Line 40 of the Dockerfile explicitly set `/usr/bin` in the PATH, which was redundant and potentially caused PATH resolution issues
- **Solution**: Changed `ENV PATH="${GOPATH}/bin:/usr/bin:${PATH}"` to `ENV PATH="${GOPATH}/bin:${PATH}"`
- **Impact**: Simplifies PATH configuration by relying on the base image's default PATH, which already includes `/usr/bin`
- **Testing**: Smoke tests should now successfully execute `go version` within the container

## Build Issues Encountered

During local testing, the container build encountered SSL/TLS certificate verification issues:
