Summary

• Preserve the signed fractional wheel/touchpad delta through the Sandbox viewport camera path instead of reducing every nonzero event to one full notch.
• Apply bounded magnitude-sensitive orthographic and perspective zoom transactionally; invalid inputs leave camera state unchanged.
• Add bounded product-process automation diagnostics and a packaged assertion that sends a real 0.25 scroll event and verifies the authoritative camera state changes.

• Focused Debug henka_tests: passed (1/1).
• Focused Release henka_tests: passed (1/1).
• Fresh Debug Sandbox build and package: passed; package marker records clean source SHA and executable hash parity.
• Full check_packaged_sandbox3d_windows.ps1 -NonInteractive -ProductStartupPrimitiveOnly: passed (exit 0), including the fractional-scroll product-state assertion and remaining packaged workflow.
• Repository integrity, public-content hygiene, and git diff --check: passed.

A pre-existing CMake object-path length warning was observed during build; it did not fail the target and no path gate was weakened.
