Safe Workspaces in Termux

$HOME is private to Termux and is the preferred location for academy labs. Shared storage is convenient but has broader visibility and different permission behavior.

Create the workspace

mkdir -p ~/dedsec-academy/{source,working,evidence,reports,backups}
chmod 700 ~/dedsec-academy
ls -ld ~/dedsec-academy

Copy before analysis

cp source/sample.log working/sample.log
sha256sum source/sample.log working/sample.log

The hashes should match before analysis. Any later change belongs in the working copy, never the source file.
