Event Types

Event ID	Description	Frequency	Category
4104	Script Block Logging	~30%	process
4103	Module Logging — cmdlet invocation	~30%	process
400	Engine State → Available	~8%	process
403	Engine State → Stopped	~8%	process
600	Provider Started	~8%	process
800	Pipeline Execution Details	~8%	process
4105	Script Block Invocation Start	~4%	process

Realism Features

Session correlation — Engine start (400) produces sessions consumed by engine stop (403)
Script block correlation — 4104 produces block IDs referenced by 4105/4106 invocation events
~15% of script blocks flagged as warning level (encoded commands, reflection APIs, crypto)
30 cmdlets with realistic frequency weights (Get-Process, Get-Service dominate)
Host application variety — powershell.exe (55%), pwsh.exe (20%), PSRemoting (15%), ISE (10%)
120-host fleet with per-host record IDs and correlation pools
