Windows folder selection can surface drive roots as D:, which Node treats as drive-relative instead of the absolute D:\ root. Normalize drive-root inputs before resolving launch directories, filesystem access roots, transcript metadata, and workspace paths. Use path.relative containment checks so drive roots and child projects remain distinct in session grouping and file access.
Constraint: Windows drive-root inputs may arrive as C:, D:, or any other single-letter drive prefix
Rejected: Special-case only D: | every Windows drive letter has the same drive-relative semantics
Confidence: high
Scope-risk: moderate
Directive: Keep Windows drive-root normalization centralized; do not reintroduce string-prefix containment checks for workspace roots
