| - **No internal multithreading requirement**: A single `Interpreter` does not need to evaluate a program using multiple threads. | ||
| - **Independent interpreters should be concurrency-friendly**: Applications should be able to run multiple independent `Interpreter` instances concurrently in the same JVM. | ||
| - **Shared mutable state is exceptional**: State should belong to an interpreter or evaluation unless it has an explicit concurrency contract and tests. | ||
|
|
Motivation: Prevent future AI-assisted changes from introducing unsafe assumptions about interpreter threading or shared state. Modification: Add a Threading Model section to CLAUDE.md covering allowed parallel evaluation, interpreter isolation, and explicit contracts for shared mutable state. Result: Repository guidance now supports future parallel evaluation while preserving deterministic behavior and cross-platform interpreter isolation.
