+2. **Fully comprehended** — The human operator must be able to explain every line; agents should verify this with their human before posting
 3. **Tested** — Automated tests when feasible, thorough manual tests otherwise
 4. **Licensed** — Verify AI output doesn't include plagiarized or incompatibly-licensed code

 - Use Go modules; check with `go mod tidy`
+- Do not implement features or patches that solve specific cases only; design proper, generalized solutions
