# Status Log

## 2026-04-11 — Case Studies for Key Principles

### Completed
- Created `docs/examples/` directory with 4 case study documents
- **#6 Cheapest Model per Task**: GitHub Copilot tiering, Anthropic model family routing, Colette two-pass pipeline
- **#9 Checkpoint / Resume**: GitLab 2017 DB loss, Apache Kafka offsets, psyresearch paper ingestion
- **#10 Diagnose Before Retrying**: Knight Capital $440M loss, AWS S3 2017 outage, microservice retry storms, agent retry loops
- **#29 Emergency Stop**: Tesla Autopilot disengagement, AWS auto-scaling runaway, OpenAI spending caps, dispatch Not-Aus
- Each case study includes: real-world scenario, followed vs violated analysis, industry cross-reference table, key insight summary
- Total: 14 case studies across 4 principles, with 24 industry cross-references

### What's Next
- Add case studies for remaining high-impact principles (e.g., #2 Vertical Spike, #14 Parallel by Default, #26 PDCA)
- Cross-link case studies from README.md principle entries
- Consider blog post or talk format

## 2026-03-31 — Project Created

### Completed
- Extracted 24 principles from workspace configs, memory files, CLAUDE.md files, and observed patterns
- Grouped into 7 themes: Architecture, Cost, Execution, Autonomy, Documentation, Capture, Content
- Each principle grounded in real usage, not theory

### Sources Mined
- Global CLAUDE.md (user instructions)
- Workspace CLAUDE.md (autonomous agent rules)
- 12 memory files (feedback, projects, user context)
- Project-specific CLAUDE.md files (claudine, affordance, 3sets)
- control-center.md, agent-handbook.md
- Colette virtual publisher plans

### What's Next
- Add concrete examples for key principles (docs/examples/)
- Cross-reference with industry patterns (12-factor app, etc.)
- Consider blog post or talk format
- Keep extracting from ongoing sessions
