Adds all 6 ROOT 01 modules (how computers run software, the shell, filesystem navigation, files & text, processes, users & permissions foundations), each with a real lesson, demonstration/guided exercise, knowledge check where warranted, a hands-on Lab, and a reflection — 35 activities, 29 new content files. Adds 6 new hands-on Linux scenarios (linux-inspect-hardware, linux-shell-basics, linux-filesystem-navigation, linux-files-and-text, linux-process-management, linux-permissions-foundations) plus 2 MCQ scenarios, using the existing generic scenario/ validation engine (docs/ROOT_FOUNDATIONS_LAB_STRATEGY.md §1) — every one tested end-to-end via the real scenario setup/validate API, including negative tests confirming they correctly FAIL when not actually solved (e.g. the process-management scenario fails while the target process is still running; the permissions scenario is tested against a real `su - labuser` denial). Wires rootnode-linux-foundations-assessment (2 required + 4 random-draw scenarios) using the existing Phase 3B assessment engine. Adds a real, server-side ROOT 01->02->03->04->05 course prerequisite chain (courses.prerequisites) — verified live on two students: one who completed ROOT 01 sees ROOT 02 unlock; a fresh student sees ROOT 02 correctly locked while 03/04/05 stay vacuously satisfied (their own prerequisite courses are still empty). ROOT 06+ and the Capstone are unaffected. Co-Authored-By: Claude Sonnet 5 <[email protected]>

Knowledge Check: Linux and the Shell
1. What's the difference between a shell and a terminal?
Answer: The terminal is the window/program that displays text and captures keystrokes; the
shell (e.g. bash) is the program actually interpreting what you type as commands. The terminal
is the display, the shell is the brain.
2. A command exits with code 0. What does that tell you?
Answer: It succeeded. 0 is the universal "success" convention every script and pipeline
relies on; any non-zero value means some kind of failure occurred.
3. You've typed half a long path and can't remember the rest. What should you press?
Answer: Tab — tab completion finishes the path (or shows the options) without you needing to type or remember it exactly.
4. Where would you look to learn every option a command supports, without leaving the terminal?
Answer: Its manual page — man <command>.
Instructor Notes
Facilitation: Question 1 is the one students most often blur together — worth confirming verbally before moving on.
