Module support 

Compatibility support-matrix accessor (read-only).

Loads the packaged support-matrix.json (copied from the evidence workstream) and exposes feature-state queries by id and category, so consumers and the CLI can report OPY support status without duplicating the matrix.

The matrix is embedded at build time via include_str! rather than loaded at runtime: the shipped artifact always carries the exact matrix CI validated, no runtime file lookup or dependency is required, and cargo rebuilds the crate automatically when the file changes. The module is a strict read-only consumer — it never writes, rewrites, or caches a modified copy of the matrix.

The five declared feature states (planned, source-supported, semantic-supported, lowering-dependent, end-to-end-supported) are documented in the matrix itself; Workshop-dependent items stay lowering-dependent and are never approximated here (repo ownership boundary: see AGENTS.md).

Structs

Feature

One support-matrix feature entry.

MatrixReference

The pinned reference identity recorded in the matrix.

MatrixSnapshot

The snapshot provenance recorded in the matrix.

MatrixSummary

The matrix summary (counts by state and category).

SupportMatrix

The machine-readable support matrix, mirroring compatibility/support-matrix.json.

SupportMatrixError

A support-matrix load failure.

Constants

FEATURE_STATES

The declared feature states (see the matrix’s states map for wording).

SUPPORT_MATRIX_SCHEMA_VERSION

The matrix schema version this module understands.
