Pin corrected Zig grammar as Rust WASM candidate

 Version output includes `cli_version`, `target`, and protocol information. Discovery and init preview return observations and unknowns. Dry-run creates neither `AGENTS.md` nor a project data directory. Add Cargo `--offline` only when dependencies are cached.
 
-The workspace requires `std`. The opt-in `wasm-precheck` build feature uses a bounded Rust worker with pinned Java, Python, TypeScript, and TSX grammar candidates. Java and TypeScript/TSX have narrow single-file fallback paths; `lint python` can provide bounded suspected syntax positions when Ruff is unavailable or no project Ruff configuration is declared. Native Ruff results take priority. It is absent from the published npm `0.1.2` package. No `no_std`, completed project-wide WASM fallback, zero-unsafe, or fastest-runtime claim is made. Runtime OS calls require safety review; a comprehensive security audit is not claimed.

-The current source-built CLI's `codeguard grammar status --format=json` reports the coverage gap without loading grammars or running lint: the pinned CodeGraph source has 30 vendored WASM files plus two distinct grammars resolved through its dependency; CodeGuard has four unqualified asset candidates (Java, Python, TypeScript, TSX) and zero released syntax capabilities. Python has a source-build-only, unqualified CLI fallback path; its report remains incomplete and cannot approve delivery. The separate [coverage inventory](grammars/codegraph-coverage.json) is not an approved asset manifest. COBOL's 16.4 MB source asset also exceeds the current Rust loader's 8 MiB limit.
+The current source-built CLI's `codeguard grammar status --format=json` reports the coverage gap without loading grammars or running lint: the pinned CodeGraph source has 30 vendored WASM files plus two distinct grammars resolved through its dependency; CodeGuard has five unqualified asset candidates (Java, Python, TypeScript, TSX, Zig) and zero released syntax capabilities. Zig uses a byte-pinned import adaptation so the corrected CodeGraph grammar can load in Rust; it has no public `lint zig` route or release qualification yet. [Zig's limited acceptance record](tests/acceptance/zig-grammar-candidate.md) distinguishes this from released syntax support. Python has a source-build-only, unqualified CLI fallback path; its report remains incomplete and cannot approve delivery. The separate [coverage inventory](grammars/codegraph-coverage.json) is not an approved asset manifest. COBOL's 16.4 MB source asset also exceeds the current Rust loader's 8 MiB limit.
