How 012 is built and the bar every change meets. Start with the rules in CLAUDE.md, then:
| Page | For |
|---|---|
| Architecture | How the engine and UI fit together |
| Extending 012 | The patterns new features and scale follow |
| UX and visual bar | The rules every change follows |
| Testing | Unit, end-to-end through libghostty, golden screens, the oracle, docs checks, demos |
| Bounds of support | Measured bounds and known bottlenecks |
| Observability | Event logs, OTLP export, DuckDB queries, the local telemetry stack |
| Releasing | The release checklist and make dist |
| The docs site | Building and previewing the Docusaurus site over these docs |
Plans are in the roadmap.
