Summary

Standardised load profiles (IOPS mix, RDP session counts, file-share patterns) emitted against a cluster and correlated with MAPROOM expected capacity assertions.

Deferral rationale

azurelocal-loadtools has the most mature test infrastructure in the org but tests the load tool itself, not the shape of load profiles. PULSE requires a MAPROOM fixture extension for capacity expectations — design after MAPROOM reaches its first real consumer set.

Acceptance criteria

• MAPROOM reaches first real consumer set
• MAPROOM fixture schema extended for capacity expectations
• Standard load profiles defined (IOPS mix, RDP session counts, file-share patterns)
• Integration with azurelocal-loadtools
• Module docs added under docs/

Target: v0.3.0+
