Reference architecture literacy — pattern ID, zone diagram stub, control overlay, integration point, version note — named reference rows on YOUR `$ARCH_LAB` LAB-ARCH-001.
Visual · t41_reference_arch_stub
Reference arch = named pattern rows. $ARCH_LAB LAB-ARCH-001. Original Cyberlium.
Opening
Reference architectures accelerate consistent design — name pattern and zone rows on YOUR lab stub before publishing stranger org architecture as YOUR reference.
Reference architecture literacy names: pattern ID row category, zone diagram stub category, control overlay category, integration point category, and version note category. Analyst documents reference architecture stub on `$ARCH_LAB` LAB-ARCH-001 — links Module 5 DMZ/segmentation and Module 7-2 EA domains — without copying vendor reference architectures without license, without presenting lab stub as certified enterprise standard, without offensive bypass annotations on zone diagrams. Cyberlium teaches reference design vocabulary on YOUR notes. Refused: stranger org architecture plagiarism, offensive bypass annotations, fake certified reference claims. Lab row: reference arch stub (pattern ID, zone stub, control overlay, LAB label).
1. Named reference rows
Pattern ID, zone diagram, control overlay, integration point, version — five literacy anchors.
Zone stub cites Module 5 pattern literacy — defensive segmentation only.

SABSA business attributes — NAMED LITERACY:
Confidentiality: protect sensitive customer/order data
Integrity: orders and billing cannot be tampered undetected
Availability: platform meets fictional 99.9% SLA literacy
Accountability: actions attributable to user/service identity
Privacy: PII handled per policy (educational — not legal advice)
Auditability: evidence for compliance reviews (LAB SAMPLE)

2. Version discipline
Version note documents lab iteration — not forged enterprise approval stamp.
Control overlay links forward to Module 8 control selection — same org thread.
3. Refused
No stranger org architecture plagiarism; no offensive bypass annotations; no fake certified reference.
Reference literacy supports reuse — not architecture fraud.
4. What you ship: reference architecture stub
Pattern ID + zone stub + control overlay + version + NEVER plagiarism line.
5. What you record before the next lesson

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
Copy stranger org reference architecture PDF and rebrand as `$ARCH_LAB` certified enterprise standard.
Right
Reference architecture stub from `$ARCH_LAB` LAB-ARCH-001. Next: Enterprise Lab.
Mission: reference architecture stub
1) Name five reference arch literacy rows. 2) Zone stub from Module 5 pattern literacy. 3) Control overlay stub for Module 8 link. 4) Write NEVER stranger org plagiarism line.
