Diagram Hygiene
Documentation standards literacy — diagram legend, version header, assumption block, control reference, LAB disclaimer — named doc rows on YOUR `$ARCH_LAB` LAB-ARCH-001.
Visual · t41_documentation_standards
Documentation standards = named doc rows. $ARCH_LAB LAB-ARCH-001. Original Cyberlium.
Opening
Architecture documentation must be readable and traceable — name standard rows on YOUR lab pack before submitting stranger org diagrams as YOUR deliverables.
Documentation standards literacy names: diagram legend category, version header category, assumption block category, control reference category, and LAB/educational disclaimer category. Analyst documents documentation standards card on `$ARCH_LAB` LAB-ARCH-001 — five standard rows applied to Modules 6–8 artifacts — without omitting LAB disclaimer, without presenting lab docs as live employer architecture without authorization, without offensive annotations in diagram legends. Cyberlium teaches documentation discipline on YOUR notes. Refused: missing disclaimers, stranger org diagram substitution, offensive legend annotations. Lab row: documentation standards card (five rows, applied example, LAB disclaimer).
1. Named documentation rows
Legend, version header, assumptions, control reference, LAB disclaimer — five anchors.
Each standard applied to one lab artifact sample — not stranger org exports.

2. Disclaimer discipline
LAB disclaimer states fictional org LAB-ARCH-001 and courseware purpose — mandatory.
Control reference links Module 8 catalog — traceability without forged compliance claims.
3. Refused
No missing LAB disclaimers; no stranger org diagram substitution; no offensive legend notes.
Documentation literacy supports professional handoff — not architecture fraud.
4. What you ship: documentation standards card
Five standard rows + applied example + LAB disclaimer + NEVER stranger org substitution line.
5. What you record before the next lesson
Documentation standards card path.
6. Wrong vs right: offensive playbooks vs YOUR threat models
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Submit stranger org architecture PDF as `$ARCH_LAB` documentation without LAB disclaimer or authorization.
Right
Documentation standards card from `$ARCH_LAB` LAB-ARCH-001. Next: Review Lab.
Mission: documentation standards card
1) Name five documentation standard literacy rows. 2) Apply each to one lab artifact sample. 3) LAB disclaimer prominent on sample. 4) Write NEVER stranger org substitution line.
