 A new `packages/hooks/` group with `hook-protocol` as a pure library. It owns four primitive families and the `hook/*` session events; each bridge plugin (`dsh-hooks-claude`, `dsh-hooks-codex`) owns what genuinely differs.
 
 **Shared (here):**
-- **Matcher** — `matcherDiagnostic(pattern, mode)` and `matchesMatcher(pattern, query, mode)`. The ONE axis the dialects differ on is collapsed to the `mode` parameter: `claude` treats a pure `[A-Za-z0-9_|]+` pattern as a literal (pipe = exact-match alternation) and anything else as a regex; `codex` is always an unanchored regex. Match-all on absent/`''`/`'*'`. Each bridge ignores unsupported events before group parsing, discards matcher fields on supported events without matcher subjects, validates the remaining runnable groups, and treats an invalid regex there as a whole-config load failure, with a stable dialect/pattern/event diagnostic; no hook listeners are registered. Runtime matching still contains an invalid regex as a non-match, so a direct library caller never throws into the loop.
+- **Matcher** — `matcherDiagnostic(pattern, mode)` and `matchesMatcher(pattern, query, mode)`. Pure `[A-Za-z0-9_|]+` patterns use the shared exact-match fast path (pipe = alternatives); the ONE remaining dialect axis is collapsed to `mode`: other Claude patterns use JavaScript `RegExp`, while other Codex patterns use Rust `regex`, including Rust-only syntax such as `(?i)`. Match-all on absent/`''`/`'*'`. Each bridge ignores unsupported events before group parsing, discards matcher fields on supported events without matcher subjects, validates the remaining runnable groups, and treats an invalid regex there as a whole-config load failure, with a stable dialect/pattern/event diagnostic; no hook listeners are registered. Runtime matching still contains an invalid regex as a non-match, so a direct library caller never throws into the loop.
 - **Execution** — `runHook(bash, hook, options)`. Runs a command hook through the `ctx.bash` seam rather than a bespoke `spawn`: the executor already provides the scrubbed-but-overridable env, process-group kills, and timeout the protocol needs, and `dsh-bash`'s `stdin`/`env` fields (added for exactly this) are the trusted-plugin surface an in-process bridge is allowed to use. It serializes the bridge-built payload to stdin (trailing newline iff CC), honors the hook's `timeoutSec` (else `DEFAULT_HOOK_TIMEOUT_MS`, the 10-minute reference default both dialects share), and never throws (an executor rejection becomes a non-blocking-error `HookOutput`).
 - **Decode** — `parseHookOutput(exit, stdout, stderr)`, the exit-code + structured-stdout codec, producing a dialect-neutral `HookOutput`. Exit `0` → lenient JSON parse of stdout; exit `2` → blocking error with `stderr` as the reason (surfaced as `decision: 'block'` so no caller needs a separate exit-code branch); other → non-blocking error. Parses the CC structured-stdout fields that have a consumer on some path (`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`); the bridge honors only the subset meaningful for its dialect. Fields with no consumer on any path are not parsed at all (CC's `suppressOutput` — hook stdout never enters a transcript here, so there is nothing to suppress; see [the tighten-hook-protocol-contract Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)).
 - **Merge** — `mergeHookOutputs(outputs)`, folding multiple matched hooks into one most-restrictive `MergedHookOutcome`: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined `\n\n`, context/system-messages accumulated in order.

 在 `packages/hooks/` 分组下新建 `hook-protocol` 作为纯库。它拥有四个原语族和 `hook/*` 会话事件；每个桥接插件（`dsh-hooks-claude`、`dsh-hooks-codex`）拥有真正不同的部分。
 
 **共享（本库）：**
-- **Matcher** — `matcherDiagnostic(pattern, mode)` 与 `matchesMatcher(pattern, query, mode)`。两种方言唯一不同的轴被收敛为 `mode` 参数：`claude` 将纯 `[A-Za-z0-9_|]+` 模式视为字面量（管道符 = 精确匹配的多选），其余视为正则；`codex` 始终是无锚定正则。缺省/`''`/`'*'` 匹配一切。每个桥接插件会在解析 group 前忽略不支持的事件，丢弃受支持但没有 matcher 匹配对象的事件所带 matcher 字段，再校验剩余的可运行 group；其中的无效正则会导致整份配置加载失败，并输出稳定的方言／模式／事件诊断，且不注册任何 hook 监听器。运行时匹配仍将无效正则收敛为不匹配，因此直接调用本库时绝不向 agent loop（智能体循环）抛异常。

 - **执行** — `runHook(bash, hook, options)`。通过 `ctx.bash` seam 而非自建 `spawn` 运行命令钩子：执行器已提供清洗但可覆盖的 env、进程组 kill 和超时，正是协议所需的能力；`dsh-bash` 的 `stdin`/`env` 字段（正是为此添加的）是进程内桥接插件被允许使用的受信插件接口。它将桥接插件构建的 payload 序列化到 stdin（CC 时追加尾部换行），遵守钩子的 `timeoutSec`（否则使用 `DEFAULT_HOOK_TIMEOUT_MS`，即两种方言共享的 10 分钟参考默认值），且从不抛异常（执行器拒绝变为 non-blocking-error 的 `HookOutput`）。
 - **解码** — `parseHookOutput(exit, stdout, stderr)`，exit-code + structured-stdout 编解码器，产出方言无关的 `HookOutput`。Exit `0` → 宽松 JSON 解析 stdout；exit `2` → blocking error，`stderr` 为原因（以 `decision: 'block'` 呈现，调用方无需单独处理 exit-code 分支）；其他 → non-blocking error。解析 CC structured-stdout 中在某条路径上有消费方的字段（`continue`/`stopReason`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`）；桥接插件只采纳对其方言有意义的子集。在任何路径上都没有消费方的字段不予解析（CC 的 `suppressOutput`——钩子 stdout 在此处从不进入 transcript（文本记录），因此无需抑制；见 [收紧钩子协议契约 Agent Note](../simplification/2026-07-04-tighten-hook-protocol-contract.md)）。
 - **合并** — `mergeHookOutputs(outputs)`，将多个匹配钩子的输出折叠为一个最严格的 `MergedHookOutcome`：权限优先级 **deny > ask > allow**，halt 在首个 `continue:false` 时粘滞，阻止原因以 `\n\n` 拼接，context/system-messages 按序累积。

-- **`matcherDiagnostic(matcher, mode)` / `matchesMatcher(matcher, query, mode)`** — match-all on absent/`''`/`'*'`; `claude` mode treats a pure `[A-Za-z0-9_|]+` pattern as a literal (pipe = exact-match alternation) and anything else as a regex; `codex` mode is always an unanchored regex. Bridge parsers discard matcher fields for events without matcher subjects, then use `matcherDiagnostic` to reject an invalid consumed regex with a stable diagnostic before registering any hooks. The runtime predicate still contains an invalid pattern as a non-match, so a direct library caller cannot throw into the agent loop.
+- **`matcherDiagnostic(matcher, mode)` / `matchesMatcher(matcher, query, mode)`** — match-all on absent/`''`/`'*'`; both dialects treat a pure `[A-Za-z0-9_|]+` pattern as exact pipe-separated alternatives. Other patterns are unanchored regexes compiled in the native dialect: JavaScript for Claude Code, Rust `regex` for Codex (including inline flags such as `(?i)`). Bridge parsers discard matcher fields for events without matcher subjects, then use `matcherDiagnostic` to reject an invalid consumed regex with a stable diagnostic before registering any hooks. The runtime predicate still contains an invalid pattern as a non-match, so a direct library caller cannot throw into the agent loop.
 - **`runHook(bash, hook, options, now)`** — require and forward the caller-owned `options.signal`, serialize `options.payload` to the hook's stdin (with a trailing newline iff `options.trailingNewline`), merge `options.env` after the executor's credential scrub (the `dsh-bash` trusted-plugin surface), honor the hook's `timeoutSec` (else `options.defaultTimeoutMs` — the bridge owns the default, its config defaulting to the lib's `DEFAULT_HOOK_TIMEOUT_MS` 10-minute reference), and decode the result (threading `options.expectedEventName` to the codec). Cancellation therefore reaches the executor's process-group kill and join boundary. Never throws: an executor rejection (infra fault) becomes a `HookOutput` with `exitCode: undefined` (a non-blocking error). `now` is injected for testable durations.
 - **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** decodes exit status and structured stdout. Exit 2 blocks with stderr; other failures are non-blocking. A matching hook-specific permission decision overrides the legacy top-level decision; mismatched or missing event discriminators suppress only event-specific fields. Top-level fields remain event-agnostic, and successful non-JSON output is left to the bridge.
 - **`mergeHookOutputs(outputs)`** — fold the results of every hook that matched one point: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined with `\n\n`, `additionalContext`/`systemMessages` accumulated in order.

 - **`runHook(bash, hook, options, now)`**：要求并转发调用方拥有的 `options.signal`，将 `options.payload` 序列化到 hook stdin（当且仅当 `options.trailingNewline` 时添加尾随换行符），在执行器凭证清理后合并 `options.env`（`dsh-bash` 受信任插件表层），遵循 hook 的 `timeoutSec`（否则使用 `options.defaultTimeoutMs`；默认值属于桥接，其配置默认为 lib 的 `DEFAULT_HOOK_TIMEOUT_MS` 10 分钟参考值），再解码结果（将 `options.expectedEventName` 传递给 codec）。因此取消会到达执行器的进程组终止与 join 边界。它绝不抛出异常：执行器拒绝（基础设施故障）会变为 `HookOutput`，其 `exitCode: undefined`（非阻塞错误）。`now` 会被注入，以便测试持续时间。
 - **`parseHookOutput(exitCode, stdout, stderr, expectedEventName?)`** 解码退出状态与结构化 stdout。退出码 2 使用 stderr 阻塞；其他失败不阻塞。匹配的 hook 特定权限决策会覆盖遗留顶层决策；事件判别字段不匹配或缺失只会抑制事件特定字段。顶层字段仍与事件无关，成功但非 JSON 的输出会留给桥接处理。
 - **`mergeHookOutputs(outputs)`**：折叠在一个点上匹配的每个 hook 结果：权限优先级为 **deny > ask > allow**，首个 `continue:false` 使 halt 粘滞，阻塞原因用 `\n\n` 连接，`additionalContext`／`systemMessages` 按顺序累积。

-- **Regex-only matchers** (no literal fast path; the matcher is always an unanchored regex).
+- **Native Codex matcher semantics:** pure word/pipe patterns are exact alternatives; other patterns are unanchored Rust `regex` expressions (including inline flags such as `(?i)`).
 - **snake_case stdin payloads** with `turn_id`/`model` extras, written **without** a trailing newline.
 - **No Codex plugin env injection and no config-time placeholder substitution** (the command still receives the executor's environment and runs through its shell).
 - **No pre-tool approval or rewrite path** — a hook can block, but the bridge does not pre-approve or replace tool input.
