| 29 | ## Working on T3 Code |
| 30 | |
| 31 | Start with the [development runbook](./operations/development.md) and |
| 32 | [contribution policy](../CONTRIBUTING.md). |
| 33 | |
| 34 | Internal notes preserve architectural decisions, constraints, and implementation traps that the |
| 35 | source alone does not explain. Most code changes do not need an internal documentation update. Follow the |
| 36 | [documentation rules](../AGENTS.md#documentation) before adding one. |
