A familiar project name does not prove that a mirror is current, unchanged or trustworthy. Review where the files came from and whether the contents match what you expected.
Avoid unexpected executables
A browser-based reference copy should not require you to run unrelated executable files just to view normal static content. Be cautious when a download adds extra installers or utilities.
Practical check
Keep the process small and testable. Make one meaningful change at a time, confirm the result, and preserve enough context to undo it if needed.
Keep a known-good backup
Before an update or customization, archive the working copy. A backup gives you a clean comparison point if something breaks.
What to avoid
Avoid mixing advice from unrelated builds as if every copy behaves identically. Version, file structure, enabled data and hosting method can all change the correct next step.
Separate trust from convenience
A convenient download source can still be outdated or modified. Verify first, then test changes in a separate folder before replacing your normal setup.
Summary checklist
- Work from a clear reference goal.
- Keep source and version context visible.
- Preserve a known-good local backup.
- Test paths and browser behavior before making broad changes.
