Adds an isolated filesystem prototype for comparing Windows NTFS bulk MFT acquisition with ordinary enumeration and Get-ChildItem. It reconstructs metadata and hardlink paths, provides C# inventory and folder totals, and exposes a thin experimental Get-FileSystemItem command. Auto keeps normal enumeration; the MFT backend requires explicit selection and elevated read-only access.

The benchmark separates fresh index acquisition, C# scanning, C# folder totals and PowerShell output. The plan and results retain failed samples, explain the guarded physical-partition read route, and document visibility, freshness, timestamp, memory and allocation limits. The prototype is excluded from the normal solution and cannot be packed or published; the shipped module is unchanged.

Validation:

• 37 focused tests pass in PowerShell 7 and Windows PowerShell 5.1, rerun for this revision with Pester 5.7.1.
• Both target builds and the independent bulk-reader review were completed during evaluation.
• The retained two-iteration large-tree and whole-volume measurements are documented in Prototypes/FileSystem/RESULTS.md. Whole-volume populations differ, so the results make no equivalent-coverage ranking.

This remains a draft for evaluation. Production integration and transparent Get-ChildItem compatibility require the open decisions and qualification work in Prototypes/FileSystem/PLAN.md.
