+# Claro Complete Platform Roadmap
+
+Current release: **Claro v1.18.26**
+
+This roadmap tracks the larger goal: Claro as a complete beginner-friendly programming platform, not only a toy scripting interpreter.
+
+## Platform pillars
+
+1. Beginner scripting core
+2. Strong but optional-feeling static safety
+3. Objects and classes for larger programs
+4. Local projects and packages
+5. Safe networking and local web apps
+6. Cooperative tasks/concurrency
+7. Editor/IDE help
+8. Optional graphics/game support
+
+## Current status summary
+
+See `CURRENT_STATUS.md` for the detailed matrix.
+
+- Stable foundation: beginner scripting core, functions, friendly CLI/checking
+- Foundation present: static types, objects/classes, packages, networking, concurrency, IDE metadata
+- Experimental/planned: SDL graphics, package registry, web server, full editor extension/LSP
+
+## Completion definition
+
+Claro should not be called a complete beginner platform until:
+
+- each pillar has at least one beginner lesson
+- each pillar has a validation command or regression test
+- historical docs are clearly separated from current docs
+- optional features fail gracefully when dependencies are missing
+- README navigation tells learners exactly where to start
+
+## Next documentation work
+
+- Keep this roadmap and `CURRENT_STATUS.md` updated after each feature change.
+- Avoid saying experimental features are ready until examples run with the stable executable.
+- Prefer small learner examples over large speculative design docs.
