Crate behavior_contracts 

behavior-contracts — language-neutral IR runtime COMMON core (Rust).

Ports the same thin COMMON primitives as the TS/Python references. No backend, key-resolution, retry-tuning, or DSL-specific concepts — those live in consumers.

Public COMMON primitives (runtime-boundary.md §2.1):

• validate_envelope — spec-version fail-closed check
• evaluate_expression — expression-ir.md normative evaluation
• render_template — {param} strict rendering
• run_plan — execution-plan skeleton (stage / Skip propagation / Policy Kind)
• canonical_value / canonical_json / py_float_repr — canonical serialization
• assert_portable — Portability Guard
• decode_value / deep_equals — conformance runner adapter COMMON part
