 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.

-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.

 Reuse pinned CodeGraph grammar WASM artifacts and applicable upstream licenses, source references, patches and corpus cases. Do not copy CodeGraph's graph extraction or source-blanking heuristics into a syntax verdict. CodeGraph's `src/extraction/grammars.ts` loads language artifacts through `web-tree-sitter`; successful loading there does not prove compatibility with Codeguard's Rust runtime. The local source review on 2026-09-28 found modified grammar artifacts and about 65 MB of grammar files, so a live directory is not a release input.

Python has a narrow source-build-only fallback for unavailable or undeclared Ruff, with native results taking priority and no delivery approval. An initialized single-file scope now syncs one stable native-confirmation task; candidate zero recoveries do not close it.

+WASM requirements and 19 implementation tasks are recorded in the existing change. Candidate Rust worker and narrow Java/TypeScript/TSX single-file reports and a Python Ruff-unavailable candidate report now exist behind an opt-in feature; all five grammars remain unqualified; Zig is only a Rust-loadable candidate.

 Use a parent-controlled parser worker with a total deadline, per-file input bound, memory/process limit and capped diagnostics. Lazy-load selected grammars, parse without general network/filesystem imports, and terminate a stuck worker without losing native results from other modules. Host-specific enforcement and Rust MSRV compatibility must be tested; numeric production budgets remain measurement-driven rather than invented promises.

 再后续的 [Python 资产候选](python-grammar-asset-candidate.md)使当前候选数变为 4；Python 尚未接入 lint，已发行能力仍为 0。上述数值均为各次增量当时的记录。
+
+2026-09-29 增量：来源库存更新到 CodeGraph `1072f82ce24db3d133258d30165cef6b74d108b2`，当前工作树 30/30 份随仓 WASM 的长度与 SHA-256 与新库存一致。Zig 源 WASM 已变更为修复空容器误报的构建；其原始字节与 Rust 适配后的候选资产、加载测试见 [Zig 局部验收](zig-grammar-candidate.md)。当前候选资产为 5，已验收发行仍为 0。`objc` 与 `solidity` 的精确字节可从 CodeGraph 锁定的 `tree-sitter-wasms@0.1.13` 本机 npm 缓存重现，但本增量尚未把它们写入 CodeGuard 资产清单或验收为可加载能力。历史 2/3/4 候选数仅表示各次验收快照。

+# Zig WASM 固定资产候选与 Rust 导入适配（2026-09-29）
+
+对应 OpenSpec 14.1、14.2、14.4、14.19，均未完成整体验收。CodeGraph `1072f82ce24db3d133258d30165cef6b74d108b2` 的 Zig 语法 WASM 是 ABI 15，SHA-256 `95d8eef504bde9cca06b7950d6a8ae177ce318d16080deac96f653b29c629f98`，705336 字节。上游 `@tree-sitter-grammars/tree-sitter-zig` 1.1.2 的源码提交、空容器补丁、构建器与 MIT 许可证来源记录在 CodeGraph `docs/grammars/tree-sitter-zig.md`；CodeGuard 保存原始 `grammars/zig/source.wasm` 和许可证。当前固定 CodeGraph 提交的另外 29 份随仓 WASM 也已逐字节核对库存，但未因此成为 CodeGuard 候选。
+
+RED：直接用 Rust `WasmStore` 加载新 Zig 原始 WASM，因缺少 `__main_argc_argv` 导入失败。旧 Zig WASM 虽能加载，却把合法 `const S = struct {};` 解析成错误；所以回退旧版会带回已知误报。新版导入表中 `__main_argc_argv` 与 `args_get` 同为 `(i32, i32) -> i32`；固定源字节适配只将 import section 的这一个导入名改成 `args_get`，不改语法表或树。Rust `adapt_zig_wasm` 同时验证原始 SHA-256、唯一导入位置及输出 SHA-256。适配后 `grammars/zig/parser.wasm` 为 705328 字节，SHA-256 `e8a3aa89cc07b59188122e6c1e0a812ca58cf85c9e191dcf2663a30b6b3b99e3`。更改来源任何字节、缺少导入或更改输出字节都不能获得固定资产身份。
+
+GREEN：离线 Rust 加载实测 ABI 15；`struct`、`enum`、`union(enum)`、`opaque` 四种合法空容器没有解析恢复，未闭合容器产生解析错误。本机 Zig 0.16.0 的 `zig fmt --check` 对同一四种空容器样例返回 0，形成一项窄范围原生对照。隔离 worker 对合法 Zig 文件返回候选观察，但 `grammar_qualified=false`，聚合结果保持 `incomplete`；`grammar status` 显示 Zig 为第五份 `candidate_unvalidated`，`released_count=0`。初检没有公共 Zig `lint/check` 路由、工作台任务与宿主对话接线，因此**不宣称 Zig 语法检查能力已发布**。完整 Zig 版本/方言覆盖、合法与非法语料、原生对照、性能与发行包均待验收。
+
+验证：`grammar_asset_manifest` 4/4，`wasm_grammar_load` 2/2，`grammar_status_cli` 2/2，`syntax_worker_candidate` 7/7；均以 `--locked` 离线构建，worker 测试启用 `wasm-precheck`。默认构建的 `cargo test --workspace --locked --quiet --no-fail-fast` 退出 0；启用 `codeguard-cli/wasm-precheck` 的全工作区、全部 targets 回归最终退出 0，共 180 组、1129 通过、106 条条件忽略、零失败。首轮特性回归暴露旧测试假定“工作区只有一张 Ruff 任务”；测试现按 `reason_code` 选取原生环境任务，同时核对候选初检的原生确认任务仍在。特性 Clippy `-D warnings`、格式、分层检查、OpenSpec strict 与 diff 检查退出 0。条件忽略的真实原生工具测试、Rust 1.85 MSRV 和发行包实装并未由这些结果证明。
