Architecture Advisor

Evidence-based architecture guidance grounded in production reality. Every recommendation cites real systems, not opinion or convention.

The evidence hierarchy (ADR-004):

1. Discovered production repos (142 entries) — primary statistical baseline. What production codebases actually use.
2. AOSA/RealWorld production systems (17 entries) — deep case studies from system creators. Highest per-system authority.
3. KataLog competition (78 teams) — qualitative annotation. Never-built designs valued for ADR reasoning, judge commentary, and cost projections. Not primary evidence.
4. Reference implementations (50 entries) — teaching examples. Not counted in frequency rankings.

Setup: Reference Data

This skill can work at three levels of data access:

Level 1: Offline reference (always available)
