chore(comments): includes 头注释英文化（R11 收尾）

把 includes 下 64 个 .vp 的文件头注释（含 traceback.vp 第 13-427 行的整块文件级说明）以及 2 处漏网的正文中文注释（ast/lexer.vp、json/__writer.vp）与 1 处中文 docstring（memhub.vp）逐行译为英文；同步把 fltk/gen_ffi.py 的生成模板与其自身注释英文化，使重新生成仍为英文。

只改注释/文档串文字：行数与代码逐字节不变（骨架比对 140 文件漂移 0），运行时中文字符串字面量 305 处保持原样。验证：三重重编 SUCCESS（170.21s）+ 全量 77/77 顺序回归通过 + VET 编译 SUCCESS / --search-paths 7 条 exit 0。

+#     (to keep a wild pointer from flying the walk off track); **all memory reads go through ReadProcessMemory, never a direct dereference of a wild rbp**.
-#     RBP 链只覆盖保持帧指针的函数；帧指针一旦未保留（[rbp+8] 不是返回地址）链即在第 1
+#     The RBP chain only covers functions that keep a frame pointer; once the frame pointer is not preserved ([rbp+8] is not the return address) the chain
-#     步断——此时由 ScanStack 兜底，另叠一层 dbghelp 加强（可用时）。
+#     breaks at step 1 -- then ScanStack is the fallback, with a further dbghelp augmentation layer on top (when available).
-#     --traceback 时 TPC 给 llc 加 `-frame-pointer=all`（Phase2Translator.py:2187-2193）；
+#     With --traceback, TPC adds `-frame-pointer=all` to llc (Phase2Translator.py:2187-2193);
-#     该 flag 是否真正生效见第十二节 C 的调查结论与修法落点。
+#     whether that flag actually takes effect is covered by the investigation result and fix location in section 12 C.
-#   【取证：先取证，再决策】每次转储在 banner 之后打印一组前置诊断（**TRACEBACK_DIAG=1 时**）——
+#   [Evidence first: gather evidence, then decide] After the banner each dump prints a set of preflight diagnostics (**only when TRACEBACK_DIAG=1**) --
-#     Seq / 回调线程 id / 主线程 id / Dumping 进入前值 / MapOk / SymReady / ModInited /
+#     Seq / callback thread id / main thread id / pre-entry Dumping value / MapOk / SymReady / ModInited /
-#     SymGetModuleBase64(主模块) 的**实际返回值** / 主模块基址 / 帧缓冲与两个回调地址
+#     the **actual return value** of SymGetModuleBase64(main module) / main-module base / whether the frame buffer and the two callback addresses
-#     是否就位；进入 dbghelp 主路径后，**首帧**再打印 StackWalk64 的返回码、传入的
+#     are in place; after entering the dbghelp main path the **first frame** additionally prints StackWalk64's return code, the
-#     machine/RIP/RSP/RBP、返回的 AddrPC，以及 SymFunctionTableAccess64(proc, AddrPC) 的
+#     machine/RIP/RSP/RBP passed in, the returned AddrPC, and the return value of SymFunctionTableAccess64(proc, AddrPC).
-#     返回值。这些行**先于任何降级判断**产出，使"0 帧"的根因可直接判定（见第九节）。
+#     These lines are produced **before any degrade decision**, so the root cause of "0 frames" can be judged directly (see section 9).
 #
 # -----------------------------------------------------------------------------
-# 五、链接期依赖（TPC 侧必须知道）
+# 5. Link-time dependencies (the TPC side must know this)
 # -----------------------------------------------------------------------------
-#   dbghelp（-ldbghelp）+ kernel32（既有）。SymInitialize / StackWalk64 / SymSetOptions /
+#   dbghelp (-ldbghelp) + kernel32 (existing). SymInitialize / StackWalk64 / SymSetOptions /
-#   SymGetModuleBase64 / SymFunctionTableAccess64 是**静态**引用（后两个用于首帧取证诊断），
+#   SymGetModuleBase64 / SymFunctionTableAccess64 are **static** references (the latter two are used for first-frame evidence),
-#   产物必须能解析 dbghelp 的导入库，否则链接失败。若不便新增 -ldbghelp，
+#   so the artifact must resolve dbghelp's import library or the link fails. If adding -ldbghelp is inconvenient,
-#   把 TRACEBACK_USE_DBGHELP 置 0：该常量比较会在编译期把唯一含 dbghelp 调用的分支
+#   set TRACEBACK_USE_DBGHELP to 0: that constant comparison folds away at compile time the only branch containing
-#   整体去掉（见 TRACEBACK_USE_DBGHELP 的注释），只保留 RBP 链回溯。
+#   dbghelp calls (see the TRACEBACK_USE_DBGHELP comment), leaving only the RBP-chain walk.
 #
 # -----------------------------------------------------------------------------
-# 六、TPC 侧调用入口（符号与签名）
+# 6. TPC-side call entry (symbol and signature)
 # -----------------------------------------------------------------------------
 #   import traceback
-#   traceback.Install()            # 返回 int：1=handler 已注册；0=未安装（无旁文件/失败）
+#   traceback.Install()            # returns int: 1 = handler registered; 0 = not installed (no sidecar/failure)
-#                                   # 注册两个：SetConsoleCtrlHandler（Ctrl+C/Break）+
+#                                   # registers two: SetConsoleCtrlHandler (Ctrl+C/Break) +
-#                                   # SetUnhandledExceptionFilter（崩溃），见第一节/第十四节
+#                                   # SetUnhandledExceptionFilter (crash), see section 1 / section 14
-#   调用时机：进程启动期一次即可。两种等价做法——
+#   Call timing: once during process startup. Two equivalent ways --
-#     (a) 在入口 main 的第一条语句调用；
+#     (a) call it as the first statement of entry main;
-#     (b) 注入一个 @llvm.global_ctors（.CRT$XCU 语义）构造器调用该符号（本仓先例：
+#     (b) inject an @llvm.global_ctors (.CRT$XCU semantics) constructor that calls this symbol (repo precedent:
-#         TransPyC/lib/core/LLVMCG/BaseGen.py:2061-2097 用 llvm.global_ctors 注册
+#         TransPyC/lib/core/LLVMCG/BaseGen.py:2061-2097 registers a Ctrl+C handler via llvm.global_ctors);
-#         Ctrl+C 处理器）。构造器在 CRT 初始化期执行，能覆盖「main 之前就卡住」的场景。
+#         the constructor runs during CRT initialization, covering the "stuck before main" case.
-#   本模块自身**没有**模块级构造器（状态对象由 Install 懒分配），故与 TPC 注入的
+#   This module itself has **no** module-level constructor (the state object is lazily allocated by Install), so it has
-#   构造器不存在初始化顺序依赖，重复调用是幂等的。
+#   no initialization-order dependency on TPC's injected constructor, and repeated calls are idempotent.
-#   ⚠ 本模块把「主线程」定义为**调用 Install() 的那个线程**（Install 里 GetCurrentThreadId
+#   NOTE: this module defines the "main thread" as **the thread that called Install()** (Install records its id
-#     记录其 id，回调时挂起/回溯的就是它）。故必须在真正的入口线程调用（main 或 CRT
+#     via GetCurrentThreadId; that is the thread suspended/walked on callback). So it must be called on the real entry
-#     构造器所在线程）；若在启动期的工作线程里调用，转储的将是那个线程的栈。
+#     thread (main, or the thread running a CRT constructor); if called on a startup worker thread, the dump is that thread's stack.
 #
 # -----------------------------------------------------------------------------
-# 七、为什么直接 WriteFile 而不是 printf
+# 7. Why WriteFile directly instead of printf
 # -----------------------------------------------------------------------------
-# 转储发生在「主线程已被挂起」的时刻：若主线程恰好停在 CRT 的 stdout 锁内，回调线程
+# The dump happens at a moment when **the main thread is already suspended**: if the main thread happens to be stopped inside
-# 再调用 printf 会**永久等待同一把锁**，把"卡死"变成"按了键彻底不动"。
+# the CRT's stdout lock, the callback thread calling printf would **wait forever on the same lock**, turning "hang" into "key press and nothing moves".
-# 故输出走 kernel32!WriteFile(GetStdHandle(STD_ERROR_HANDLE))（无用户态 CRT 流锁），
+# So output goes through kernel32!WriteFile(GetStdHandle(STD_ERROR_HANDLE)) (no user-mode CRT stream lock),
-# 格式化走 CRT snprintf（只写内存缓冲，不碰 FILE 锁）。stderr 的另一好处：stdout 常被
+# and formatting goes through CRT snprintf (writes only to a memory buffer, never touching FILE locks). Another benefit of stderr: stdout is often
-# 管道占用（如被父工具读取），stderr 一般直达终端。句柄与全部缓冲都在 Install 时备好，
+# taken by a pipe (e.g. read by a parent tool) while stderr usually goes straight to the terminal. Handles and all buffers are prepared at Install,
-# 回调线程**零分配**（MemBuddy 非线程安全，回调里绝不触碰池）。
+# and the callback thread does **zero allocation** (MemBuddy is not thread-safe; the callback never touches the pool).
 #
 # -----------------------------------------------------------------------------
-# 七之二、转储**同时落文件** + 控制台纯 ASCII（本轮的两次修正）
+# 7b. Dump **also written to a file** + pure-ASCII console (two fixes this round)
 # -----------------------------------------------------------------------------
-# (a) 落文件（解决"没有 Break 键"与"控制台代码页吞字"）：Install 成功时以
+# (a) File output (solves "no Break key" and "console code page eats characters"): on successful Install, open an
-#     `<exe 完整路径> + ".stackdump.txt"` 打开一个**追加写**句柄（OPEN_ALWAYS +
+#     **append** handle for `<exe full path> + ".stackdump.txt"` (OPEN_ALWAYS +
-#     FILE_APPEND_DATA，不存在则创建），EmitLine 把**同一份内容**既写控制台又追加落盘。
+#     FILE_APPEND_DATA, creating it if absent); EmitLine writes **the same content** both to the console and appending to disk.
-#     文件是 UTF-8 字节原样，不受控制台代码页影响；每次转储在段前追加一小段分隔头
+#     The file is raw UTF-8 bytes, unaffected by the console code page; each dump prepends a small separator header
-#     （本地时间戳/pid/触发键/主线程 id/Seq，中文标签，仅文件）。文件写失败**不阻断**
+#     (local timestamp/pid/trigger key/main thread id/Seq, Chinese labels, file only). A file write failure **does not block**
-#     控制台，且只提示一次（见 EmitToFile）。Install 成功时打印一行
+#     the console and is reported only once (see EmitToFile). On successful Install it prints a line
-#     `[traceback] stack dump also written to: <路径>` 便于确认去向。
+#     `[traceback] stack dump also written to: <path>` to confirm the destination.
-# (b) 控制台纯 ASCII：原先的运行时文本是中文（UTF-8 字节），而 cmd 的控制台输出代码页
+# (b) Pure-ASCII console: the runtime text was originally Chinese (UTF-8 bytes), while cmd's console output code page
-#     默认为 936(GBK)——WriteFile 到控制台会按 936 解释 UTF-8 字节，一段多字节在多次
+#     defaults to 936 (GBK) -- WriteFile to the console interprets UTF-8 bytes as 936, and a multi-byte sequence split/rejoined
-#     WriteFile 之间被拆开/重组，表现为**整行消失**（最长的"首帧"行首当其冲）或相邻行错位、
+#     across several WriteFile calls appears as **whole lines disappearing** (the longest "first frame" line first) or adjacent lines shifting,
-#     看似"重复且残缺"（含 '�'）。故**运行时输出到控制台的文本一律改英文/ASCII**
+#     looking "duplicated and mangled" (including the U+FFFD replacement character). So **all runtime text sent to the console is changed to English/ASCII**
-#     （banner / [diag] / Trigger= / exe base= / walk: primary=rbp_chain / frames=N 等），
+#     (banner / [diag] / Trigger= / exe base= / walk: primary=rbp_chain / frames=N, etc.),
-#     任何代码页下都可读、可 grep；`  File "<文件>", line <行>, in <函数名>` 帧行保留源路径
+#     readable and greppable under any code page; the `  File "<file>", line <line>, in <function>` frame line keeps the source path
-#     原文（分隔符/新增说明文字一律 ASCII）。
+#     text as-is (separators/added explanatory text are always ASCII).
-#     中文仅保留在：本文件的注释/文档串、以及**只写文件**的分隔头。
+#     Chinese is kept only in: this file's comments/docstrings, and the **file-only** separator header.
 #

-# 八、依赖的既有声明（未改动）与本模块新增声明
+# 8. Existing declarations relied on (unchanged) and declarations added by this module

+#   New this round: wc.SetConsoleCtrlHandler / wc.CTRL_C_EVENT / wc.CTRL_BREAK_EVENT;
-#         wp.CONTEXT（x64 完整布局）/ wp.CONTEXT_FULL / wp.GetThreadContext；

-#         编译器内部函数、无导出符号、不可链接）。
+#         a compiler intrinsic, has no exported symbol, and is not linkable).
-#   本轮新增（真 Python traceback 输出）：kernel32!GetEnvironmentVariableA 的**本模块自声明**
+#   New this round (real Python traceback output): **this module's own declaration** of kernel32!GetEnvironmentVariableA
-#         （win32base 未声明，仓库仅 VET/App/lib/VDirs.vp:45 有；kernel32 本就链接，TPC/TPV 均

+#         TPV can resolve it), used for the TRACEBACK_DIAG switch; everything else uses only existing APIs (see section 13).
 #
 # -----------------------------------------------------------------------------
-# 九、"0 帧"的可执行结论（哪种情形 → 看哪个现场字段）
+# 9. Actionable conclusions for "0 frames" (which case -> which live field to look at)
 # -----------------------------------------------------------------------------
-#   ⚠ 本节所有取证行都是 `[diag]` 行，故**只在 TRACEBACK_DIAG=1 时产出**（见第十三节 C）；
+#   NOTE: every evidence line in this section is a `[diag]` line, so it is **produced only when TRACEBACK_DIAG=1** (see section 13 C);
-#     排查"0 帧"时请先用 `set TRACEBACK_DIAG=1` 启动目标进程。
+#     when investigating "0 frames" first start the target process with `set TRACEBACK_DIAG=1`.
-#   首帧取证两行（"    [diag] StackWalk64 first: ret=… addrpc=… fta=…" 与紧随其后的
+#   The two first-frame evidence lines ("    [diag] StackWalk64 first: ret=... addrpc=... fta=..." and the one immediately after,
-#   "    [diag] StackWalk64 in: machine=… rip=… rsp=… rbp=…"——原为单条 143 字符长行，
+#   "    [diag] StackWalk64 in: machine=... rip=... rsp=... rbp=..." -- originally one 143-char line,
-#   拆成两条短行以消除窄终端折行造成的"显示残缺"假象，字段一个不减）
+#   split into two short lines to remove the "mangled display" illusion caused by wrapping in a narrow terminal, with no field dropped)
-#   与前置诊断行（"[diag] Seq=… … modinited=…" / "SymGetModuleBase64(main)=…"）合起来直接给出结论：
+#   together with the preflight lines ("[diag] Seq=... ... modinited=..." / "SymGetModuleBase64(main)=...") directly give the conclusion:
-#   (1) modinited == 0 且 SymGetModuleBase64(main) == 0 ⇒ dbghelp 的模块表不含主模块。
+#   (1) modinited == 0 and SymGetModuleBase64(main) == 0 => dbghelp's module table does not contain the main module.
-#       根因是 SymInitialize 的 fInvadeProcess 参数（必须 TRUE）或调用时机（要在进程启动期、
+#       Root cause is SymInitialize's fInvadeProcess argument (must be TRUE) or the call timing (it must be called during process
-#       模块枚举可用时调用，本模块放在 Install 里）。修法：确认 Install 里 SymInitialize 的
+#       startup while module enumeration is available; this module does it in Install). Fix: confirm Install's SymInitialize
-#       第三个实参为 1，且 Install 在入口线程、模块全部加载后调用；必要时改用
+#       third argument is 1, and that Install is called on the entry thread after all modules are loaded; if needed use
-#       SymRefreshModuleList 重新枚举。
+#       SymRefreshModuleList to re-enumerate.
-#   (2) 首帧 ret == 0，且紧邻有 "[diag] readmem failed addr=… size=… GetLastError=…"
+#   (2) first frame ret == 0 with an adjacent "[diag] readmem failed addr=... size=... GetLastError=..."
-#       ⇒ 读栈内存失败。`ReadProcessMemory` 在回调里返回 0 会让 StackWalk64 立刻终止（=0 帧）。
+#       => reading stack memory failed. A `ReadProcessMemory` returning 0 in the callback makes StackWalk64 stop at once (= 0 frames).
-#       修法：核对 ReadMemCb 的宽度口径（dbghelp 侧是 DWORD nSize + LPDWORD，kernel32 侧是
+#       Fix: check ReadMemCb's width convention (dbghelp side is DWORD nSize + LPDWORD, kernel32 side is
-#       SIZE_T，本模块已用本地 sizet 承接再写回 DWORD）与进程句柄/权限。
+#       SIZE_T; this module receives into a local sizet then writes back as DWORD) and the process handle/privileges.
-#   (3) 首帧 ret != 0 但返回 addrpc == 0，或 fta（SymFunctionTableAccess64(addrpc)）== 0
+#   (3) first frame ret != 0 but returned addrpc == 0, or fta (SymFunctionTableAccess64(addrpc)) == 0
-#       ⇒ 上下文/模块基址口径问题（传给 StackWalk64 的 RIP/RSP/RBP 或模块基址不对）。
+#       => a context/module-base convention problem (the RIP/RSP/RBP passed to StackWalk64 or the module base is wrong).
-#       修法：核对 CONTEXT 的 Rip/Rsp/Rbp 取值与 GetModuleHandleA(NULL) 基址。
+#       Fix: check CONTEXT's Rip/Rsp/Rbp values against the GetModuleHandleA(NULL) base.
-#   补充：首帧行里 `ret=not-called` 表示 SymInitialize/回调地址/帧缓冲前提不全、根本没调用
+#   Note: `ret=not-called` in the first-frame line means the SymInitialize/callback-address/frame-buffer preconditions are incomplete and
-#   StackWalk64（此时该行仍会产出，保证"转 RBP 链"之前永远有首帧证据）。
+#   StackWalk64 was never called (the line is still produced then, guaranteeing first-frame evidence always exists before "switching to the RBP chain").
-#   三者互斥且可判：只要把上面两组打印字段与判据对照，就能**当场**确定属于哪一类。
+#   The three cases are mutually exclusive and decidable: just compare the two printed field groups above against the criteria to determine **on the spot** which case it is.
 #
 # -----------------------------------------------------------------------------
-# 十、本轮新增的两组定位打印（应答"walk 到底跑到没有"与"重复残缺真因"）
+# 10. Two groups of locating prints added this round (answering "did the walk run at all" and "the real cause of duplicate/mangled")
 # -----------------------------------------------------------------------------
-#   A. walk 是否被调用、走了哪条出口（全部走 DumpMainThread / WalkViaDbgHelp 的既有输出通道；
+#   A. Whether the walk was called and which exit it took (all via DumpMainThread / WalkViaDbgHelp's existing output channels;
-#      这些行**只在 TRACEBACK_DIAG=1 时输出**）：
+#      these lines are **output only when TRACEBACK_DIAG=1**):
-#      * DumpMainThread 在**调用前**打 "    [diag] walk: enter use_dbghelp=… symready=…
+#      * DumpMainThread prints, **before the call**, "    [diag] walk: enter use_dbghelp=... symready=...
-#        modinited=… frame_buf=… mapok=… asan=…"，**调用后**打 "    [diag] walk: leave
+#        modinited=... frame_buf=... mapok=... asan=...", and, **after the call**, "    [diag] walk: leave
-#        frames=… mapok=…"。两行都在 ⇒ walk 一定进了 RBP 主路径（dbghelp 加强可选）。
+#        frames=... mapok=...". Both lines present => the walk did enter the RBP main path (dbghelp augmentation optional).
-#      * 若 **连 walk: enter 都不出现**（且 TRACEBACK_DIAG=1）⇒ DumpMainThread 在本行之前就返回：
+#      * If **even walk: enter does not appear** (and TRACEBACK_DIAG=1) => DumpMainThread returned before this line:
-#        只可能是三处 fallback（OpenThread / SuspendThread / GetThreadContext 失败，各自都有
+#        it can only be one of three fallbacks (OpenThread / SuspendThread / GetThreadContext failing, each with its own
-#        "fallback: … cannot dump stack" 行）——据该行即可定位被跳过的分支。
+#        "fallback: ... cannot dump stack" line) -- that line locates the skipped branch.
-#      * WalkViaDbgHelp 的**每一条 return** 都先打 "    [diag] walk: return reason=<…> frames=…"，
+#      * **Every return** in WalkViaDbgHelp first prints "    [diag] walk: return reason=<...> frames=...",
-#        reason ∈ {null_state, disabled, null_frame_buf, null_context, stackwalk_first_failed,
+#        with reason in {null_state, disabled, null_frame_buf, null_context, stackwalk_first_failed,
-#        stackwalk_failed, addrpc_zero, frame_limit}（含义见函数内注释），故 walk 的走向
+#        stackwalk_failed, addrpc_zero, frame_limit} (meanings in the in-function comments), so the walk's path
-#        必可判定、不再靠猜。本轮起主路径是 RBP 链，DumpMainThread 另打
+#        is always decidable, never guessed. Since this round the main path is the RBP chain; DumpMainThread additionally prints
-#        `walk: primary=rbp_chain` / `walk: rbp_chain frames=…` / `walk: dbghelp enhancement engaged`；
+#        `walk: primary=rbp_chain` / `walk: rbp_chain frames=...` / `walk: dbghelp enhancement engaged`;
-#        dbghelp 不可用时另打 `[diag] symwalk=disabled reason=…`（见第十一节 B）。
+#        when dbghelp is unavailable it additionally prints `[diag] symwalk=disabled reason=...` (see section 11 B).
-#   B. "重复残缺"真因的判别凭据（唯一凭据 = 行号是否重复）：
+#   B. Evidence for the real cause of "duplicate/mangled" (the only evidence = whether line numbers repeat):
-#      * EmitLine 在 **TRACEBACK_DIAG=1** 时给**每一行**加全局递增前缀 "    [dump#<k>] "
+#      * EmitLine adds a globally increasing prefix "    [dump#<k>] " to **every line** when **TRACEBACK_DIAG=1**

+#        traceback form (see section 13).
-#      * 同一段文本出现多份且**序号重复**（同一 k 出现两次）⇒ 该文本被写了两次，即**并发写
+#      * The same text appearing several times with **repeated numbers** (the same k twice) => that text was written twice, i.e. **concurrent writes to
-#        同一 LineBuf**；此时才需要"输出互斥"。同一序号不可能出自单线程的一次 EmitLine。
+#        the same LineBuf**; only then is "output mutual exclusion" needed. The same number cannot come from a single-threaded EmitLine.
-#      * 文本被**截断/换行错位**但**序号严格递增、无重复** ⇒ 内容只写了一次（乱不了号），
+#      * Text **truncated / line-wrapped out of place** but with **strictly increasing, non-repeating numbers** => the content was written once (numbers cannot be scrambled),
-#        只可能是**终端长行折行/回显**层的显示效果；修法是缩短长行（本轮已把三条最长行拆短），
+#        so it can only be a **terminal long-line wrap/echo** display effect; the fix is to shorten long lines (this round split the three longest),
-#        **不动锁**。
+#        **without touching the lock**.
-#      * 本轮补打：`[dump#skip]` 仅在使用输出互斥时才需要；本模块判定为"显示层"，
+#      * Added this round: `[dump#skip]` is only needed when output mutual exclusion is used; this module judged it a "display-layer"
-#        故未加互斥、未打印该标记（判据与结论见交付说明）。
+#        issue, so no mutual exclusion was added and that marker is not printed (criteria and conclusion in the delivery notes).
 #
 # -----------------------------------------------------------------------------
-# 十一、本轮两根因修复（崩溃 = 属性访问被降级；0 帧 = dbghelp 与环境互斥）
+# 11. Two root-cause fixes this round (crash = attribute access silently demoted; 0 frames = dbghelp conflicting with the environment)
 # -----------------------------------------------------------------------------
-# A. **崩溃根因不是分配失败，而是 TPC 把 `_State.<字段>` 静默降级成常量 null。**
+# A. **The crash root cause is not an allocation failure but TPC silently demoting `_State.<field>` to the null constant.**
-#    实测证据（构建产物 IR，模块前缀 = 本文件 sha1 前 16 位 9b4ee486e08837c5）：
+#    Evidence (build-artifact IR; module prefix = first 16 hex digits of this file's sha1, 9b4ee486e08837c5):
-#      * 源码 `string.memset(_State.FrameBuf, 0, …)` 被生成为
+#      * The source `string.memset(_State.FrameBuf, 0, ...)` was generated as
-#        `call i8* @memset(i8* null, i32 0, i64 248)` —— 参数就是字面 null；
+#        `call i8* @memset(i8* null, i32 0, i64 248)` -- the argument is the literal null;
-#        同一函数里 `_State.LineBuf`（snprintf）、`_State.FuncTableAddr / ModuleBaseAddr`
+#        in the same function `_State.LineBuf` (snprintf), `_State.FuncTableAddr / ModuleBaseAddr`
-#        （StackWalk64 的两个回调槽）同样全被折成 null。
+#        (StackWalk64's two callback slots) were likewise all folded to null.
-#      * `Install` 里的 `calloc(1,248)` 与其"分配失败即 return 0"的判空**都在且正确**
+#      * `Install`'s `calloc(1,248)` and its null check "return 0 if allocation failed" **are both present and correct**
-#        （IR 里 `@calloc` 返回值被正常 store 到字段 20），故**不是** calloc 返回 NULL。
+#        (in the IR `@calloc`'s return value is stored to field 20 normally), so it is **not** calloc returning NULL.
-#    机理（TPC 侧，只报不改）：`TransPyC/lib/core/Handles/HandlesExprAttr.py`
+#    Mechanism (TPC side, report only, no change): `TransPyC/lib/core/Handles/HandlesExprAttr.py`
-#      `_resolve_var_classname`（约 L285-293）对 `rawptr[X]` 形态的模块级全局只看
+#      `_resolve_var_classname` (approx. L285-293) looks only for a module-level global of the form `rawptr[X]` at
-#      `GVar.type.pointee`（= `X*`，仍是指针）⇒ 认不出 `X`，返回 None；兜底的
+#      `GVar.type.pointee` (= `X*`, still a pointer) => it fails to recognize `X` and returns None; the fallback
-#      `_recover_struct_class`（约 L723-740）虽能多解一层指针，但要求 `X` 已进入
+#      `_recover_struct_class` (approx. L723-740) can peel one more pointer level, but requires `X` to already be in
-#      **函数级**的 `Gen.variables/global_vars`（`HandlesFunctions.py:1848` 每函数清空），
+#      the **function-level** `Gen.variables/global_vars` (`HandlesFunctions.py:1848` clears it per function),
-#      而该登记只发生在"裸名 `X` 被求值一次"时（`HandlesExpr.py:479/487`）。
+#      and that registration only happens when "the bare name `X` is evaluated once" (`HandlesExpr.py:479/487`).
-#      ⇒ 凡**一上手就直接读写 `_State.<字段>`、且函数内从未单独求值过裸名 `_State`
+#      => For any function that **reads/writes `_State.<field>` right at the start and never separately evaluates the bare name `_State`
-#        的函数**，`_handle_attr_name` 在 L507-508 返回 None：
+#        inside the function**, `_handle_attr_name` returns None at L507-508:
-#          - 作为调用实参 ⇒ 被静默替换为 null（→ memset(null) 崩溃）；
+#          - as a call argument => silently replaced with null (-> memset(null) crash);
-#          - 作为 `if X == None:` 的条件 ⇒ 整个 `if` 被 `HandlesIf` L170-171 丢弃
+#          - as the condition of `if X == None:` => the whole `if` is dropped by `HandlesIf` L170-171
-#            （→ 我们原来写的 `if _State.FrameBuf == None: …` **根本没被生成**）。
+#            (-> the `if _State.FrameBuf == None: ...` we originally wrote **was never generated**).
-#      受影响函数（IR 佐证：这些函数体内 `@_State` 的 load 次数为 0）：
+#      Affected functions (IR corroboration: these function bodies load `@_State` 0 times):
-#        `EntryRva` / `LookupRva` / `EmitFrame` / `WalkViaDbgHelp`。
+#        `EntryRva` / `LookupRva` / `EmitFrame` / `WalkViaDbgHelp`.
-#      其余函数（`EmitLine` / `DumpMainThread` / `ReadMemCb` / `Install` …）入口都有
+#      Other functions (`EmitLine` / `DumpMainThread` / `ReadMemCb` / `Install` ...) all have a
-#        `_State == None` 判空 ⇒ 裸名已登记 ⇒ 字段访问正常（这就是为什么
+#        `_State == None` null check at entry => the bare name is registered => field access works (this is why
-#        `DumpMainThread` 打出的 `frame_buf=1`、`modinited=1` 都是真的）。
+#        the `frame_buf=1`, `modinited=1` printed by `DumpMainThread` are real).
-#    本模块的修法（**不去改 TPC**）：凡直接使用 `_State.<字段>` 的函数，入口
+#    This module's fix (**without changing TPC**): every function that uses `_State.<field>` directly gets
-#      **第一句就写 `if _State == None: …`**（即使是冗余判空）——它既是真正的兜底，
+#      **`if _State == None: ...` as its very first statement** (even if redundant) -- it is both a genuine fallback
-#      也把裸名 `_State` 登记进 `Gen.variables`，使其后的字段访问被正常解析。
+#      and registers the bare name `_State` into `Gen.variables`, so later field accesses resolve normally.
-#      崩溃点再加一道局部量兜底：`FBuf: VOIDPTR = _State.FrameBuf` → 判 `FBuf == None`
+#      At the crash point add one more local-variable fallback: `FBuf: VOIDPTR = _State.FrameBuf` -> check `FBuf == None`
-#      → `memset(FBuf, …)`，把"局部变量"这条最可靠的通道用在最危险的一行上。
+#      -> `memset(FBuf, ...)`, using the most reliable channel (a local variable) on the most dangerous line.
-# B. **0 帧 / DbgHelp 状态共享**：ASan 运行时会自己注册 DbgHelp 符号化器，本模块的
+# B. **0 frames / DbgHelp state sharing**: the ASan runtime registers its own DbgHelp symbolizer, so this module's
-#    SymInitialize 因此被拒（DbgHelp 进程上下文是**进程级**状态、按句柄唯一）。但这**不是
+#    SymInitialize is rejected (the DbgHelp process context is a **process-level** state, unique per handle). But this is **not
-#    冲突**：状态是共享的，用同一个 GetCurrentProcess() 伪句柄即可复用其模块表。故 Install
+#    a conflict**: the state is shared, and using the same GetCurrentProcess() pseudo-handle reuses its module table. So Install's
-#    的判定改为**取证式**三步：SymInitialize 成功 → SymReady=1；失败 → SymRefreshModuleList
+#    decision becomes an **evidence-based** three-step one: SymInitialize succeeds -> SymReady=1; fails -> SymRefreshModuleList
-#    刷新共享模块表（官方"外部初始化后再刷新"写法）；再统一用 SymGetModuleBase64(主模块)
+#    refreshes the shared module table (the official "refresh after external init" idiom); then a SymGetModuleBase64(main module)
-#    探针裁决——探针为 0 则 SymReady 回退 0 并打印原因，绝不静默 0 帧。回溯路径顺序：
+#    probe arbitrates -- if the probe is 0, SymReady falls back to 0 and the reason is printed, never a silent 0 frames. Walk-path order:
-#      * 主路径 = `WalkRbpChain`（纯 RBP 链，**零 dbghelp 依赖**）；
+#      * main path = `WalkRbpChain` (pure RBP chain, **zero dbghelp dependency**);
-#      * **第二兜底 = `ScanStack` 栈扫描**（零 dbghelp、且**不依赖 RBP / 帧指针**）：
+#      * **second fallback = `ScanStack` stack scan** (zero dbghelp and **no RBP / frame-pointer dependency**):
-#        RBP 链只拿到当前 RIP（<=1 帧）时启用（`walk: fallback=stack_scan`），见第十二节；
+#        enabled when the RBP chain yields only the current RIP (<=1 frame) (`walk: fallback=stack_scan`), see section 12;
-#      * dbghelp 加强：只有 RBP 链拿不到更多帧（<=1）且 DbgUsable != 0（= 探针通过）时才走
+#      * dbghelp augmentation: only when the RBP chain yields no more frames (<=1) and DbgUsable != 0 (= probe passed) does it run
-#        `WalkViaDbgHelp`。它**清空已收帧并整段重建**（顺带丢掉扫描推断帧），是唯一能用 PE
+#        `WalkViaDbgHelp`. It **clears the collected frames and rebuilds the whole stack** (dropping scan-inferred frames too) and is the only path that can use the PE
-#        展开表（.pdata）穿过**无帧指针的系统帧**、回到 .vp 栈的路径——Ctrl+C 的典型现场
+#        unwind table (.pdata) to cross **frame-pointer-less system frames** back to the .vp stack -- the typical Ctrl+C scene
-#        （主线程阻塞在系统 DLL 里、RBP=0）只有它能还原真实调用链。
+#        (main thread blocked in a system DLL, RBP=0) can only have its real call chain recovered by it.
-#      * 降级**必须给原因**（不静默 0 帧）：`[diag] symwalk=disabled reason=…`，
+#      * A degrade **must give a reason** (no silent 0 frames): `[diag] symwalk=disabled reason=...`,
-#        reason ∈ {compile_time_switch, syminitialize_failed_or_main_module_missing,
+#        reason in {compile_time_switch, syminitialize_failed_or_main_module_missing,
-#        callback_missing, null_frame_buf}；ASan 探测用 GetModuleHandleA 两个常见
+#        callback_missing, null_frame_buf}; the ASan probe uses GetModuleHandleA with two common
-#        ASan 运行时名（clang_rt / libclang_rt 前缀），**只用于诊断行**，不再参与裁决。
+#        ASan runtime names (clang_rt / libclang_rt prefixes), **for diagnostic lines only**, no longer part of the decision.
-#    `WalkRbpChain` 同步加固（升级为主路径后它必须"绝不把卡死变成崩溃"）：
+#    `WalkRbpChain` is hardened in step (after becoming the main path it must "never turn a hang into a crash"):
-#      * 读 [rbp]/[rbp+8] 一律走 `wm.ReadProcessMemory`（**不直接解引用**野 rbp）；
+#      * reads of [rbp]/[rbp+8] always go through `wm.ReadProcessMemory` (**no direct dereference** of a wild rbp);
-#      * **每一步无条件打 `[diag] rbp:` 原始读数 + 判定**（先取证后决策，含被拒步；见第十二节）；
+#      * **every step unconditionally prints `[diag] rbp:` raw readings + verdict** (evidence before decision, including rejected steps; see section 12);
-#      * 自洽校验：非 0 / 8 字节对齐 / `[rbp] > rbp` / 单步跨度 <= RBP_MAX_STEP /
+#      * self-consistency checks: non-zero / 8-byte aligned / `[rbp] > rbp` / single-step span <= RBP_MAX_STEP /
-#        返回地址落在主模块基址区间 [Base, Base+TRACEBACK_MODULE_MAX) 内才**接受**该帧。
+#        return address within the main-module base range [Base, Base+TRACEBACK_MODULE_MAX) -- only then is the frame **accepted**.
 #
 # -----------------------------------------------------------------------------
-# 十二、本轮新增：RBP 链逐步原始读数 + 栈扫描兜底（应答"栈走不长"）
+# 12. New this round: per-step RBP-chain raw readings + stack-scan fallback (answering "the walk is too short")
 # -----------------------------------------------------------------------------
-# 现场（用户实测，`#0` 已正确解析：RIP 在主模块、映射/查表/帧 #0 全对）：`#1 = 0x121fa`
+# Live case (user measurement, `#0` resolved correctly: RIP in the main module, mapping/lookup/frame #0 all correct): `#1 = 0x121fa`
-#   ——远小于主模块基址、也不是栈地址 ⇒ 链在第 1 步即断。⇒ 先把"断在哪一步、为什么断"
+#   -- far below the main-module base and not a stack address => the chain breaks at step 1. => First turn "where it broke and why"
-#   变成可读数据，再补一条**不依赖 RBP**的路径。
+#   into readable data, then add a path that **does not depend on RBP**.
-# A. **逐步原始读数**（`WalkRbpChain` 内，前缀 `[diag] rbp:`，**先于任何 reject 早退**，
+# A. **Per-step raw readings** (inside `WalkRbpChain`, prefix `[diag] rbp:`, **before any reject early-return**,
-#    TRACEBACK_DIAG=1 时才输出）：
+#    output only when TRACEBACK_DIAG=1):
-#      frame=<i> rbp=0x… [rbp]=0x… [rbp+8]=0x…        ← 读到的原始 8 字节值
+#      frame=<i> rbp=0x... [rbp]=0x... [rbp+8]=0x...        <- raw 8-byte values read
-#      frame=<i> rpm_ok=<0/1> rpm_err=<GetLastError> accept=<0/1> reject_reason=<…>
+#      frame=<i> rpm_ok=<0/1> rpm_err=<GetLastError> accept=<0/1> reject_reason=<...>
-#    reject_reason ∈ {rbp_zero, not_aligned, rpm_failed, ret_zero, ret_out_of_module,
+#    reject_reason in {rbp_zero, not_aligned, rpm_failed, ret_zero, ret_out_of_module,
-#    not_growing, step_too_large}；被接受时 reason=`accept`、accept=1。
+#    not_growing, step_too_large}; when accepted, reason=`accept`, accept=1.
-#    仅被接受的步才 FramePush 入帧缓冲（旧实现在校验前就输出，会把 `0x121fa` 这类垃圾值当成
+#    Only accepted steps are FramePush-ed into the frame buffer (the old implementation output before validating, printing garbage values like `0x121fa`
-#    一帧 external 打出来，误导读者）。三种断链根因据此一眼可分：读失败 / 值本身不是返回
+#    as an external frame, misleading the reader). The three chain-break root causes are distinguishable at a glance: read failure / the value itself is not a return
-#    地址（帧指针未保留）/ 被自洽校验档掉。
+#    address (frame pointer not preserved) / rejected by the self-consistency checks.
-# B. **栈扫描兜底**（`ScanStack`）：RBP 链 <=1 帧时启用（`walk: fallback=stack_scan`）。
+# B. **Stack-scan fallback** (`ScanStack`): enabled when the RBP chain yields <=1 frame (`walk: fallback=stack_scan`).
-#    在 [RSP, RSP+2MiB) 内按 8 字节步长遍历，**4 KiB/块整块读**（失败即停并打地址/err）；
+#    Scans [RSP, RSP+2MiB) in 8-byte steps, **reading 4 KiB per chunk whole** (stops on failure and prints address/err);
-#    候选 = 落在主模块区间、且**相邻 8 字节字（A-8 或 A+8）像栈地址**的字；按值去重、
+#    a candidate = a word within the main-module range whose **adjacent 8-byte word (A-8 or A+8) looks like a stack address**; de-duplicated by value,
-#    上限 64（诊断打 `scan_candidates=<N>`）；推断帧入缓冲时带 Scanned=1，打印时在帧行末尾加
+#    capped at 64 (diagnostic prints `scan_candidates=<N>`); inferred frames enter the buffer with Scanned=1 and append
-#    ` [inferred]`（`  File "…", line 0, in <unknown> [inferred]`）明确标注**扫描推断**
+#    ` [inferred]` (`  File "...", line 0, in <unknown> [inferred]`) to the frame line to mark them clearly as **scan inferences**
-#    （可含误报，不与权威帧混淆，见第十三节）。全部读取只经 ReadProcessMemory，
+#    (may contain false positives; never confused with authoritative frames; see section 13). All reads go only through ReadProcessMemory,
-#    绝不直接解引用主线程内存（诊断设施不许把"卡死"变成"崩溃"）。
+#    never a direct dereference of main-thread memory (a diagnostic facility must not turn a "hang" into a "crash").
-# C. **帧指针是否保留**（调查结论与 TPC 侧修法落点，本模块只报不改）：
+# C. **Whether the frame pointer is preserved** (investigation conclusion and TPC-side fix location; this module reports only, no change):
-#    * 单一 llc 调用点 = `TransPyC/lib/Projectrans/Phase2Translator.py:2160 _llc_compile`，
+#    * The single llc call site = `TransPyC/lib/Projectrans/Phase2Translator.py:2160 _llc_compile`,
-#      它在 `--traceback` 打开时把 `-frame-pointer=all` 追加到命令（2187-2193）；
+#      which appends `-frame-pointer=all` to the command when `--traceback` is on (2187-2193);
-#      App 模块（如 `TransPyV/App/lib/core/Gen/Expr/ExprGenOps.vp`，模块 sha1
+#      the App module (e.g. `TransPyV/App/lib/core/Gen/Expr/ExprGenOps.vp`, module sha1
-#      `8a96a2885bae09ca`）走的是**同一个**调用点（2608 的 _dso.ll / 2319 的内联合并），
+#      `8a96a2885bae09ca`) goes through the **same** call site (2608's _dso.ll / 2319's inlining merge),
-#      故 flag 的落点本身没问题。
+#      so the flag's location itself is fine.
-#    * 缓存失效：App 模块 obj = `output/{sha1}.obj`，`_compile_ll_files` 见其存在即跳过
+#    * Cache invalidation: App module obj = `output/{sha1}.obj`, `_compile_ll_files` skips it if it exists
-#      （2621），但 `--traceback` 时 `hotspot_on`（1144）为真 ⇒ 1196-1204 会删除旧 obj
+#      (2621), but with `--traceback` `hotspot_on` (1144) is true => 1196-1204 deletes the old obj
-#      强制重编；include 模块另有隔离目录 `includes.binary_traceback`（3097-3099）+
+#      to force recompilation; the include module has a separate isolated dir `includes.binary_traceback` (3097-3099) +
-#      旧 obj 删除（3181-3190）。⇒ App/include 都不会静默复用"无帧指针的旧 obj"。
+#      old-obj deletion (3181-3190). => Neither App nor include silently reuses a "frame-pointer-less old obj".
-#    * 交付结论：若 `[diag] rbp:` 显示 `[rbp+8]` 仍不是返回地址（`ret_out_of_module`），
+#    * Delivery conclusion: if `[diag] rbp:` shows `[rbp+8]` is still not a return address (`ret_out_of_module`),
-#      则说明 `-frame-pointer=all`（llc 默认值级别的开关）没有生效，最稳的改法是在**IR 里
+#      then `-frame-pointer=all` (a flag at the level of an llc default) did not take effect; the most robust fix is to annotate
-#      按函数显式标注** `"frame-pointer"="all"` —— 落点
+#      `"frame-pointer"="all"` explicitly per function **in the IR** -- location
-#      `TransPyV/App/lib/core/Gen/Func/FuncGenBase.vp`（属性拼装 `_append_llvm_attr`，154-181）
+#      `TransPyV/App/lib/core/Gen/Func/FuncGenBase.vp` (attribute assembly `_append_llvm_attr`, 154-181)
-#      与 `TransPyC/lib/core/Handles/HandlesFunctions.py:1735`（`func.attributes.add('noredzone')`
+#      and `TransPyC/lib/core/Handles/HandlesFunctions.py:1735` (next to `func.attributes.add('noredzone')`
-#      旁）—— 让帧指针成为**函数属性**而非 llc 命令行默认值，从根上免疫"llc 是否采纳默认值"。
+#      ) -- making the frame pointer a **function attribute** rather than an llc command-line default, immune at the root to "whether llc honors the default".
-#    * 【补充实测，Test/LLvmLiteTest Ctrl+C】`RBP=0x0`、RIP 落在系统 DLL：拒绝原因是
+#    * [Extra measurement, Test/LLvmLiteTest Ctrl+C] `RBP=0x0`, RIP in a system DLL: the reject reason is
-#      `rbp_zero`（不是 `ret_out_of_module`）⇒ 断链点**不在 .vp 函数**，而在被中断的那一层
+#      `rbp_zero` (not `ret_out_of_module`) => the break is **not in a .vp function** but in the interrupted
-#      系统帧。RBP 是 callee-saved，但系统/CRT 的免帧指针代码会把它当**临时寄存器**用
+#      system frame. RBP is callee-saved, but frame-pointer-less system/CRT code uses it as a **scratch register**
-#      （`xor ebp,ebp` 是常见的清零写法），故中断现场的 RBP 与"最近一个维护帧指针的祖先"
+#      (`xor ebp,ebp` is a common zeroing idiom), so the interrupted site's RBP is unrelated to "the nearest ancestor
-#      无关。⇒ 结论：**给 .vp 函数保留帧指针无法救这条路**（链在更内层就已断），只有基于
+#      that maintains a frame pointer". => Conclusion: **keeping a frame pointer for .vp functions cannot save this path** (the chain is already broken further in); only
-#      PE 展开表（.pdata）的回溯（dbghelp!StackWalk64，见第十一节 B）才能从这种现场还原
+#      PE unwind-table (.pdata) based walking (dbghelp!StackWalk64, see section 11 B) can recover
-#      真实调用链。帧指针开关因此**不是**本轮的修法落点，保留在上仅作历史记录。

 # -----------------------------------------------------------------------------
-# 十四、崩溃转储（未处理异常；应答"崩溃无错误堆栈"）
+# 14. Crash dump (unhandled exception; answering "crash has no error stack")
 # -----------------------------------------------------------------------------
-# A. 动机：Ctrl+C 有栈，**崩溃没有**——ASan 一旦过了它的报告窗口就什么都不打印，OS 默认只留一个
+# A. Motivation: Ctrl+C has a stack, **a crash does not** -- once ASan passes its report window it prints nothing, and the OS leaves only
-#    退出码（同一处崩溃实测：开 ASan = 0x80000003 STATUS_BREAKPOINT(int3)，关 ASan =
+#    an exit code (measurements of the same crash: ASan on = 0x80000003 STATUS_BREAKPOINT(int3), ASan off =
-#    0xC0000005 ACCESS_VIOLATION，两者都**没有堆栈**）。故 Install 追加注册
+#    0xC0000005 ACCESS_VIOLATION; neither has **a stack**). So Install additionally registers
-#    kernel32!SetUnhandledExceptionFilter(CrashHandler)，由 CrashHandler → DumpCrashThread
+#    kernel32!SetUnhandledExceptionFilter(CrashHandler), and CrashHandler -> DumpCrashThread
-#    在**出错线程**上补出这条缺失的栈。
+#    produces the missing stack on the **faulting thread**.
-# B. DumpCrashThread 的三条纪律：
+# B. DumpCrashThread's three rules:
-#      * **绝不吞异常**：过滤器恒定返回 EXCEPTION_CONTINUE_SEARCH(0)，退出码 / WER / ASan 报告
+#      * **Never swallow the exception**: the filter always returns EXCEPTION_CONTINUE_SEARCH(0); exit code / WER / ASan report
-#        的行为原样保留，本模块只加堆栈；
+#        behavior is preserved; this module only adds the stack;
-#      * **不解引用 OS 指针**：EXCEPTION_POINTERS（{ExceptionRecord, ContextRecord}）与
+#      * **Never dereference OS pointers**: EXCEPTION_POINTERS ({ExceptionRecord, ContextRecord}) and
-#        EXCEPTION_RECORD 头部（u32 ExceptionCode / u32[…] ExceptionAddress）一律经
+#        the EXCEPTION_RECORD header (u32 ExceptionCode / u32[...] ExceptionAddress) are always read via
-#        ReadProcessMemory 读取；
+#        ReadProcessMemory;
-#      * **不写 OS 的 CONTEXT**：StackWalk64 每走一帧都会回写它遍历的那条记录，故先把 OS 给的
+#      * **Never write the OS's CONTEXT**: StackWalk64 writes back to the record it walks on every frame, so first copy the OS-provided
-#        CONTEXT 拷进 _State.ContextBuf（尺寸已与 winnt.h 对齐 0x4D0）再从副本走栈。
+#        CONTEXT into _State.ContextBuf (size already aligned with winnt.h, 0x4D0) and walk from the copy.
-# C. 走栈顺序与打印：dbghelp 优先（崩溃点通常在系统 DLL 里，RBP 链必然无从下手）→ RBP 链 →
+# C. Walk order and printing: dbghelp first (the crash point is usually in a system DLL, where the RBP chain is hopeless) -> RBP chain ->
-#    栈扫描，与 Ctrl+C 路径同一套 WalkViaDbgHelp / WalkRbpChain / ScanStack 与 PrintFrames；
+#    stack scan, the same WalkViaDbgHelp / WalkRbpChain / ScanStack and PrintFrames as the Ctrl+C path;
-#    与 Ctrl+C 转储**共用同一把重入锁**（AtomicTryEnterDump），故一次只可能有一份 dump：
+#    it **shares the same reentrancy lock** with the Ctrl+C dump (AtomicTryEnterDump), so only one dump can exist at a time:
-#    崩溃若发生在转储进行中，本次崩溃不转储（锁被占），避免二次伤害。
+#    if a crash happens while a dump is in progress, this crash is not dumped (lock held), avoiding a second hit.
-#    输出形状：`=== TPC crash dump (unhandled exception; the process keeps terminating) ===`
+#    Output shape: `=== TPC crash dump (unhandled exception; the process keeps terminating) ===`
-#    → `    Trigger=unhandled-exception code=0x… addr=0x… av_kind=… av_addr=0x… crashthread=…`
+#    -> `    Trigger=unhandled-exception code=0x... addr=0x... av_kind=... av_addr=0x... crashthread=...`
-#    → `    exe base=… RIP=… RSP=… RBP=…` → `    regs: rcx=… rdx=… r8=… r9=… r12=…`
+#    -> `    exe base=... RIP=... RSP=... RBP=...` -> `    regs: rcx=... rdx=... r8=... r9=... r12=...`
-#    → 与 Ctrl+C 逐字同形的 Traceback 帧（含源码行回读）→ `    frames=N` → 落文件提示
+#    -> Traceback frames word-for-word identical to Ctrl+C (including source-line re-read) -> `    frames=N` -> file-output notice
-#    → `=== crash dump end ===`。
+#    -> `=== crash dump end ===`.
-#    * `av_kind`/`av_addr` 取自 EXCEPTION_RECORD 的 ExceptionInformation[0/1]（0=读 1=写 8=执行；
+#    * `av_kind`/`av_addr` come from EXCEPTION_RECORD's ExceptionInformation[0/1] (0=read 1=write 8=execute;
-#      数据地址），只在 0xC0000005 类访问违规时有效——崩溃现场正是"原始数字胜过猜测"的场合；
+#      data address) and are valid only for 0xC0000005 access-violation-type faults -- a crash site is exactly where "raw numbers beat guessing";
-#    * `regs` 给的是**出错帧的实参现场**（Win64 前 4 个整型实参 = rcx/rdx/r8/r9；r12 是该帧
+#    * `regs` gives **the argument state of the faulting frame** (Win64's first 4 integer arguments = rcx/rdx/r8/r9; r12 is the register that frame
-#      用来解引用指针的寄存器）：一条就能区分「实参传错」与「实参对、指针所指内容错」，
+#      uses to dereference a pointer): one line distinguishes "wrong argument passed" from "argument correct, pointed-to content wrong",
-#      不必再来一轮重编。Ctrl+C 路径不打印它（那里没有"出错指令的算子"可看）。
+#      with no need for another rebuild. The Ctrl+C path does not print it (there is no "operand of the faulting instruction" to see there).
-#    * **不打印 `[RBP+8]` 当返回地址**：.vp 帧的 RBP 是 locals base（`leaq N(%rsp), %rbp`），
+#    * **Does not print `[RBP+8]` as a return address**: a .vp frame's RBP is a locals base (`leaq N(%rsp), %rbp`),
-#      返回地址在 RBP + 帧字节数 - 8（逐函数不同；实测 _TypePrintDepth 是 RBP+0x38），
+#      and the return address is at RBP + frame size - 8 (varies per function; measured _TypePrintDepth is RBP+0x38),
-#      `[RBP+8]` 只是无关局部量。调用者一律以 .stackmap 走栈结果为准。
+#      `[RBP+8]` is just an unrelated local. Callers always rely on the .stackmap walk result.
-#    中文件头（栈转储/触发=）只属于 Ctrl+C 路径，崩溃路径不动它。
+#    The Chinese file header (stack dump/trigger=) belongs only to the Ctrl+C path; the crash path leaves it alone.
-# D. 已知边界：ASan 的 VEH 优先于未处理异常过滤器——若某次崩溃由 ASan 正常报告（它自带堆栈），
+# D. Known boundaries: ASan's VEH takes priority over the unhandled-exception filter -- if a crash is reported normally by ASan (which has its own stack),
-#    本路径不会被调用；本路径覆盖的正是「ASan 报不出来 / 没开 ASan」那两类（实测的两个退出码
+#    this path is not called; this path covers exactly the two cases where "ASan cannot report it / ASan is off" (the two measured exit codes
-#    都在其中）。栈耗尽类崩溃（本路径自身也需要栈）不在保障范围内。
+#    are both among them). Stack-exhaustion crashes (this path itself needs stack) are out of scope.
