PRD Alignment Fixes: - disable-package-management.sh: Keep dpkg-query executable for audit tools (was disabled despite comments claiming it was preserved) - run.sh: Replace silent FDE skip with explicit warning message (PRD FR-011 says mandatory but host has no LUKS) - run.sh: Fix checksum generation to use post-rename filename (was referencing live-image-amd64.hybrid.iso instead of knel-football-secure.iso) Documentation Updates: - STATUS.md: Add FR-012 to alignment matrix (was missing) - STATUS.md: Fix stale requiretty reference (was removed) - STATUS.md: Update PRD coverage to 12/12 - JOURNAL.md: Replace audit entry with comprehensive fix entry 💘 Generated with Crush Assisted-by: GLM-5.1 via Crush <crush@charm.land>
