warble_claude_code/ir.rs
1//! Typed view of the Warble IR (`warble_ir_version: 0.5`) that this back-end consumes.
2//!
3//! Mirrors [`ir-schema.md`][spec-ir] field-for-field. The IR JSON is the language-neutral seam
4//! between the front-end compiler and any back-end: this module depends on the schema doc, not on
5//! the front-end's Rust types. Enum arms cover every schema-valid value; arms this target does not
6//! yet realize are rejected at emit time (a "wall-hit"), not at deserialization.

17/// cross-target lockstep owner is `core/tests/ir_version_lockstep_tests.rs`; this target's
18/// `ir_version_tests.rs` covers only its own rejection behavior. An unrecognized

41/// tier with no mapping is a loud-fail. Kept as `String` so the seam never constrains the vocabulary.
