## 🎯 What This Pack Tunes

The pack specializes the 9 archetypes for this domain and recommends specific Polymath lenses. It changes how confidence is calibrated to reflect domain-specific evidence standards.

## 🎭 Archetype Calibration

| Standard Archetype | EA-Tuned Role |
|---|---|
| 🛠️ Practitioner | **Platform Engineer / SRE** — built and operated systems at scale |
| 🎓 Academic | **CS Researcher** — distributed systems, ML systems, formal verification |
| 🤔 Skeptic | **Senior Architect with Project Scars** — has seen frameworks fail |
| 💰 Economist | **CIO / CTO with Budget Authority** — total cost of ownership |
| 📜 Historian | **IT Transformation Historian** — ERP/SOA/Big Data/Cloud cycles |
| 🔮 Futurist | **Platform Strategist** — AI/cloud/edge/agentic convergence |
| ⚖️ Regulator | **Security / Compliance Architect** — GDPR, EU AI Act |
| 🔥 Contrarian | **Anti-Platform Advocate** — replication over scaling |
| 🕵️ Insider | **Vendor Solutions Architect** — what's actually delivered vs sold |

## 📊 Domain-Specific Data Sources & Evidence Standards

Weight: production case studies over vendor benchmarks, total cost of ownership over upfront licensing, post-mortems and incident reports, Conway's Law analysis of actual organizational structure, multi-year operational data.

Skeptical of: vendor-sponsored success stories, pilot metrics extrapolated to scale, "best practices" without specified context, reference architectures detached from organizational structure.

## 🎚️ Confidence Calibration Notes

- **HIGH:** Multiple production deployments at scale, across industries, converging post-mortems
- **MODERATE:** Validated at scale in a few cases; pilot-tested broadly
- **LOW:** Pilot-stage evidence, vendor claims, single-case studies
- **UNKNOWN:** Pre-pilot, theoretical, or vendor-only claims

Be aggressive about flagging LOW for pilot performance — pilot-to-scale gap is the dominant failure mode.
