📝 WalkthroughWalkthroughCandyHole.sh was refactored to introduce a configurable, multi-path installation approach for Paqet. The script now supports local archives, dynamic extraction, library compatibility fixes, post-install verification, server secret key generation, and enhanced network discovery with MAC address resolution and user validation prompts.

In `@CandyHole.sh`:
- Around line 288-307: The script relies on the caller's CWD and doesn't
validate file operations; create and use a dedicated temp working directory
(mktemp -d) before using LOCAL_PATH/DOWNLOAD_URL/PAQET_FILE to avoid clobbering
unrelated files, run show_progress around safe downloads and check wget's exit
code and that PAQET_FILE exists and is a regular file before extraction, ensure
tar extraction succeeds (check exit code), validate PAQET_BINARY exists after
extraction and before moving, and then atomically install to
/usr/local/bin/paqet (or another intended destination) while checking
mv/permission errors and failing fast (exit non-zero) on any step so installs
are directory-safe and reliably validated.
- Around line 285-301: Add SHA256 integrity checks before extracting PAQET_FILE:
after using LOCAL_PATH or downloading via DOWNLOAD_URL (the blocks using
print_info/show_progress/wget and variable PAQET_FILE), compute and verify the
archive's SHA256 against a trusted expected hash (or by downloading a signed
checksum file) using sha256sum -c (or equivalent), and abort with print_error
and exit 1 if verification fails; ensure both the local-file branch (LOCAL_PATH)
and the download branch perform the same verification prior to calling tar -xzf,
and include clear error logging on mismatch.

Add checksum verification before extracting archive in root installer.
Lines 291 and 300 download and extract untrusted artifacts without integrity validation. Running as root, this creates a critical supply-chain risk—any MITM attack, corrupted download, or repository compromise directly executes arbitrary code with full privileges.
The upstream release exists and includes the expected Linux asset. Add SHA256 verification:

Make installation directory-safe and fail fast on file ops.
Line 288/Line 300 depend on caller CWD, and Line 307 doesn’t validate install success. This can break installs or overwrite unrelated files.
