Removed:
- The [string]\ parameter
- The \ variable
- The 'Create app-data dir with restricted ACLs' step block
- The AppData reference in the .DESCRIPTION docstring
Per the user's 2026-06-18 'NEVER USE APPDATA' directive. Tier 2 state
and failure reports now live inside the clone (scripts/tier2/state/
and scripts/tier2/failures/); no external dir needs to be created.
