Summary
We established a deterministic Unreal Engine build lane on Linux and produced a hash-verified packaged output for BC1's verification project.
Why it matters
This validates that the production pipeline can produce reproducible build artifacts with verifiable evidence.
What was achieved
- Unreal Engine source build installed and verified on Linux
- BC1 verification project build/cook/package completed successfully on Linux
- Artifacts and logs were hashed and verified (0 checksum failures)
Next steps
- Add Win64 packaging via a Windows runner
- Import Win64 artifacts into the same milestone evidence bundle
- Continue expanding automated verification gates
