Local Build Parity

Intent

Ensure the same toolchain runs locally and in CI

Implementation Considerations

Scripts

• _scripts/publisher.sh pins IG Publisher and Java version
• _scripts/sushi.sh pins SUSHI version
• Cache publisher and node modules in CI

Docker (optional)

• Provide Dockerfile with pinned tools
• Mount repo and run make build

Benefits

• Fewer "works on my machine" issues

Trade-offs

• Container build time
