Visual · t35_concepts_lab
Lab: purple concepts pack. $PURPLE_LAB only. Original Cyberlium.
Opening
Concepts pack merges roles to methodology to comms — paperwork before detection engineering module.
Lessons 2-1–2-3 named red blue purple, methodology, and roles comms. This lab merges three cards into one $PURPLE_LAB concepts artifact with M1 ethics cross-reference. No stranger-network sims or third-party tenant work — purple concepts paperwork only. Next: Quiz — Purple Concepts.
1. Lab contract: purple concepts pack
Create $HOME/cyberlium-lab/t35-m02-l04-concepts-lab.txt merging red blue purple, methodology, and roles comms sections with $PURPLE_LAB fictional exercise and M1 ethics cross-reference.
Optional: one-line note which fictional org name you used — lab labels only.

- red-blue-purple.txt: team role literacy
- purple-methodology.md: plan → simulate → detect → tune loop
- purple-roles-comms.txt: exercise roles + comms
## Integrity
- Collaborative detection validation — not offensive stranger sims

2. Cross-check refusal boundaries
Grep pack for stranger-network sim refs, third-party tenant targeting, live victim breach scripts — redact or delete. Pack stays documentary literacy.
Update pack if you rename lab hosts — note new fictional labels.
3. Lock the proof
chmod 600 on the pack. Quiz next — then Detection as Code.
Purple concepts literacy feeds detection engineering lessons in M3.
4. What you ship: purple concepts pack for $PURPLE_LAB
Merged roles, methodology, comms sections. $PURPLE_LAB named. NO stranger sims. chmod 600.
5. What you record before the next lesson
Date. Concepts pack path. $PURPLE_LAB named. File t35-m02-l04-concepts-lab.txt chmod 600.
6. Wrong vs right: stranger networks vs YOUR purple lab
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Include stranger-network sim steps in pack. Skip methodology section.
Right
Write YOUR purple concepts pack for $PURPLE_LAB. chmod 600. Next: Quiz — Purple Concepts.
Mission: freeze YOUR purple concepts pack
1) Merge M2 literacy sections. 2) Confirm zero stranger-network or third-party tenant refs. 3) Link M1 ethics cross-ref. 4) chmod 600.
