+# Prototype Code Standards (Relaxed)
+
+Prototypes are throwaway code for validating ideas. Standards are intentionally
+relaxed to maximize iteration speed. The goal is learning, not production quality.
+
+## What's Allowed in Prototypes
+- Hardcoded values (no need for data-driven config)
+- Minimal or no doc comments
+- Simple architecture (no dependency injection required)
+- Singletons and global state
+- Copy-pasted code (no need for abstraction)
+- Debug output left in place
+- Placeholder art and audio
+- Quick-and-dirty solutions
+
+## What's Still Required
+- Each prototype lives in its own subdirectory: `prototypes/[name]/`
+- Every prototype MUST have a `README.md` with:
+  - What hypothesis is being tested
+  - How to run the prototype
+  - Current status (in-progress / concluded)
+  - Findings (updated when prototype concludes)
+- No production code may reference or import from `prototypes/`
+- Prototypes must not modify files outside `prototypes/`
+- Prototypes must not be deployed or shipped
+
+## When a Prototype Succeeds
+If a prototype validates a concept and the feature moves to production:
+1. The prototype code is NOT migrated directly — it is rewritten to production standards
+2. The prototype `README.md` findings inform the production design document
+3. The prototype directory is preserved for reference but never extended
+
+## Cleanup
+Concluded prototypes should be archived or deleted after findings are captured.
+Never let prototype code grow into production code through incremental "cleanup."
