- Added a check in `blueforce-install.sh` to ensure the script is run with root privileges, providing user-friendly error messages and guidance for launching with sudo or using check mode. - Updated `01-precheck.sh` to conditionally require root privileges based on the check mode, allowing for non-root execution in read-only mode. - Modified test scripts to reflect changes in the installation process, ensuring accurate reporting of the Python console's presence and adjusting expectations accordingly.

# Network is informational here and never a gate: an offline install takes its
|
||
# packages from the local bundle, so it needs neither the Internet nor the
|
||
# central endpoint. Three things are reported separately for the operator:
|
||
# 1. local network link — no intent, not used by the install,
|
||
# 2. Internet — NOT required for an offline install (no warning),
|
||
# 3. central connection — not needed during install; that is the enrollment
|
||
# stage's job.
|
||
# This module therefore never fails because a network probe failed.
|
||
#
|
||
# Idempotent: safe to re-run. Supports --check for read-only verification.
|
||
# Exit codes: 0 = OK, 3 = SKIP (optional step, nothing to do), 1 = real failure.
