2026-10-03 CG METHOD owned practice. Python3.10+ shared_path.py and create_clip_list.py need only standard libraries. No network requests, mount lookup, clipboard or deletion. Windows PowerShell code was tested as input, not with -File: current host blocks .ps1 file execution; no execution policy change. Extract-Practice.ps1 uses an already available official 7-Zip executable and a NEW output folder. Our test used official portable7za26.03; this ZIP does NOT redistribute vendor executables. practice-files.zip has3 harmless text files including same basename in separate folders and Japanese/spaces. t tests archive integrity, not malware safety. Never extract unknown archives as part of this practice. Disk-Read.ps1 reads device/disk/partition/volume only; it does not reproduce a faulty external SSD. CFU helper writes a new UTF8 reference list, does not create target folders, and does not prove Tablacus native use. shared_path.py converts explicit UNC/SMB text only; local C: paths and guessed /Volumes mappings are rejected. Mac Automator/Finder and real SMB access are not validated. HTML files display actual local test results, not vendor app GUI screens. Keep old outputs under another name to undo practice; no normal files/settings are changed.
