Minimal router — the linked docs are the source of truth.
- Monorepo layout, build, test: docs/contributing/monorepo.md and docs/contributing/architecture.md
- Verifying fixes at runtime (real desktop dev build + simulator app, fully scriptable e2e — use this to verify PRs, not just unit tests): docs/contributing/runtime-verification.md
- CI and trusting fork PRs: docs/contributing/ci.md
- Releasing: docs/contributing/releasing.md
