+Always build and test. 
+Maintain the full testing pyramid: unit tests, static analysis, 
+linters, integration tests, and end-to-end coverage. 
+Continuously execute against the roadmap.
+
+Keep files small and focused. 
+Target <100 LOC per file unless there is a clear and 
+documented reason otherwise. 
+Enforce one responsibility per file.
+
+Decompose aggressively. 
+Break up large blobs of logic into composable units. 
+Large files are a smell.
+
+Use structured architecture. 
+Prefer plugin / service / controller patterns with explicit dependency injection.
+
+Favor declarative designs. 
+Declarative workflows are strongly preferred over imperative glue code.
+
+Everything as a workflow. 
+If something is not part of a workflow, question whether it should be executed at all. 
+Even complex systems (including game engines) can be expressed this way.
+
+Eliminate repetition. 
+Loop, parameterize, and abstract instead of copy-pasting similar code.
+
+Externalize data. 
+If you see a list, map, or configuration embedded in code, 
+it likely belongs in JSON (or equivalent).
+
+Modular configuration. 
+If JSON files grow large, 
+split them and reference them hierarchically.
+
+Ship templates, not chores. 
+Package concepts as reusable templates instead of forcing users to configure from scratch.
+
+Logging is mandatory. 
+Use structured logging with clear 
+levels (DEBUG / INFO / TRACE / ERROR) throughout the system.
+
+Declarative workflows first. 
+Increase usage wherever possible.
+
+Innovate continuously. 
+Avoid stagnation; improve structure, clarity, and expressiveness over time.
+
+Roadmap discipline. 
+If you run out of ROADMAP.md tasks, stop and report. 
+We should reassess priorities before inventing work.
