Record original-alignment implementation and traceability checkpoint

Capture current source, content data, tests, asset licenses, and original-specification traceability. Original implementation remains incomplete. The accepted matching UI generation passed 154 suites and 12,253 checks, with eight rendered staff-contract screens reviewed. Latest native Windows and full-original acceptance remain outstanding.
