05: Decision Log - Lesson 1: The Architect's Criteria (DDIA)

📋 Decision Summary​

  • Status: ✅ GO
  • Authorized Phase: Phase 06: Final Synthesis

🔍 Evaluation​

  • Structural Integrity: The "Three-Legged Stool" Epitome is the dominant governor. The "High-Rise" analogy is consistent throughout all concepts.
  • Curiosity Debt: All external terms (Netflix, Chaos Monkey, SRE) have been bound with inline IFO logic.
  • Seductive Details: No anecdotal fluff detected.
  • Resolution vs. Load: Exactly 4 core concepts with targeted Pixels (Fault vs Failure, Scaling Modes, Fan-out, Accidental Complexity). This is optimal for a 90-minute block.

⚠️ Known Risks​

  • The Twitter "Fan-out" story is the most complex part of the draft. It will require clear visual framing in the final synthesis.

🎯 Next Steps​

Design the final "System Boot" simulation and promote to docs/lessons/ddia/01_foundations.md.
