behavior-contracts 0.1.2

Language-neutral IR runtime core (expression evaluation, template rendering, execution plan, canonical serialization) shared across DSL implementations. Passes the dsl-contracts conformance vectors byte-for-byte.

//! 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
