Receives `contextStore` with tech stack, framework, codebase root, output_dir. ## Workflow **MANDATORY READ:** Load `shared/references/two_layer_detection.md` for detection methodology. 1) Parse context + output_dir 2) **Determine project type (Layer 2 pre-check):** Is this a web service (all checks apply), CLI tool (health/probes not applicable), or library (most checks optional)? Adjust applicable checks accordingly. 3) Check observability patterns (Layer 1: grep) 4) Analyze context per candidate (Layer 2): - Structured logging: is this a library (no logging OK) or a service (logging required)? - Health endpoints: web service -> required. CLI/library -> skip - Request tracing: monolith -> less needed. Microservice -> critical 5) Collect confirmed findings 6) Calculat...
