# EM-PEO-07 provider comparison

Claude and Grok independently require distinct Absence, Worklog and Timesheet identities; Work Calendar and Availability remain derived, Time Approval remains aggregate-owned and WM-ACT-008 remains reference-only. Both reject worklog as presence, productivity, quality or capacity evidence and preserve DST, overlap and additive-correction semantics. The single frozen audit upheld the boundary and found 16 artifact defects; all were remediated without rerun.
