Summary

Align the standalone New-LogEntry implementation with the IT-ToolBox 3.0.1 logger fixes, correcting destination validation, macOS case-alias locking and timeout error reporting.

Scope

• Reject non-filesystem log destinations before file operations.
• Preserve buffered entries when a flush destination is rejected.
• Share mutex identities for case-only path aliases on macOS.
• Correct timeout exception formatting.
• Add regression tests and document the path and locking boundaries.

The public API remains unchanged. Non-filesystem destinations now raise an error instead of potentially creating an unintended local file.

On case-sensitive macOS volumes, distinct case-only filenames may share a lock. Upgrade concurrent writers together because older versions can generate different lock names.

Validation

• Pester tests run — 35 passed, 0 failed on macOS
• Module imports successfully — not applicable; standalone loader tested instead
• Documentation updated where needed
• No unrelated files changed

Notes

Regression tests cover cross-process lock contention, provider-path rejection and buffer retention. The changed logger helpers have matching executable code in both repositories.

Windows and Linux validation runs through CI. Locks remain path-based; symlink and hard-link aliases are not resolved to a shared file identity.
