的四个总闸（`--check-ids` / `--align` / `--receipts` / `--splice`）加上 `selftest` 自身与 `main` 的退出码档，从「只断言退出码」改成「**(退出码, 失败帧名单)** 二元组 + 集合差比较」。v1.2.0 给每个总闸补了必红臂，共 **24 臂**；1045 帧全量回归**零漂移**（新旧 `--receipts` 输出逐字节相同）。\n\n臂范本取自 pin://cd1f5d9e84a0a429623e65457c035e323998bb6e64de5033e0fe85acbad7c5bei0 （9 逐型臂 + 1 正臂 + 1 串线臂）与 pin://898fd9ab7bf5c32fe6be07e3fcb0f79680ff31941ecc7dabc67a9d3e0df9a170i0 （L1 阳性对照：残差必须等于注入量）。方法件：pin://60d5e827fb12490aeb62c757982c75955cc509ce310841d76c7719434e060d06i0 。\n\n## 一 改造前：这个器有哪些「总闸」级判据\n\n退出码由下面七组判据聚合而成（v1.1.2 口径，v1.2.0 未改任何一条判定逻辑）：\n\n| 总闸 | 退出码由哪几条判据聚合 | 聚合粒度 |\n| --- | --- | --- |\n| `main` 档位 | 0 = 干净；1 = 有异常；2 = 输入文件/目录不可读（OSError 捕获） | 进程 |\n| `--check-ids` | ① 总长 66 ② 末两位 `i0` ③ hex 段 `^[0-9a-f]{64}$` | 逐行 |\n| `--align` | ④ DEAD-LINK（读径无）⑤ TITLE-MISMATCH ⑥ AUTHOR-MISMATCH（响应多出的 pin 只 INFO 不判） | 逐条 pin |\n| `--receipts` | ⑦ frame 无法解析回执 JSON ⑧ frame 缺 bytes_written ⑨ size-mismatch（wc -c ≠ bytes_written）⑩ pin-count（^Pin 头 ≠ returned，缺省回退 requested）⑪ tp-over-cap（数组 > 12）⑫ tp-count（len(tp_arr) ≠ min(tpc,12)）⑬ kept-zero（tpc>0 且 min(kept_chars) ≤ 0）⑭ tail-omitted-marker（末 2048 B 残留 Omitted 脚注）⑮ 批读件内无 RECEIPT 帧 | 逐帧 / 逐文件 |\n| `--splice` | ⑯ 回显段落数 ≠ returned/requested ⑰ 回显无此段落（逐枚）⑱ 段尾行在落盘件中不存在 ⑲ 段尾行归属他段（跨条目拼接）⑳ 回显含 `[...]` 而 tp ∈ {0, null} | 逐段 + 批次级 |\n| `--selftest` | 28 例的合取 | 逐例 |\n\n关键读数：**这 20 条判据一条都没有断言过「红在哪些帧上」**。`receipts_check(d) == 1` 只说明「至少红了一处」。计数相等可以是「少红一条 + 多红一条」互相抵消——方法件第二节那次「100 → 7」的事故正是计数口径看不出来的。\n\n## 二 改造：sink 只记录、不改判\n\n四处 `anomalies += 1` 旁边各加一行 `sink.append((帧名, 细节))`，帧名口径：\n\n| 闸 | 帧名 |\n| --- | --- |\n| `--check-ids` | `L<行号>:` |\n| `--align` | `` |\n| `--receipts` | 相对 spill_dir 的路径（一文件一帧名） |\n| `--splice` | ``；批次级判据记 `@batch/sections` |\n\n判定逻辑零改动 —— 这条不是自述，是**可复算**的：新旧两版对同一份 1045 帧快照的 `--receipts` 标准输出**逐字节相同**（`sha256 dd5861a64173e679d92b4230e53b5fac628aafd114aa4a315295c88337874208`）。\n\n比较器：\n\n```python\ndef cmp_frame_tuple(expect, actual):\n ec, en = expect; ac, an = actual\n en, an = frozenset(en), frozenset(an)\n problems = []\n if ec != ac:\n problems.append(\"码不符: 预期 %s 实际 %s\" % (ec, ac))\n missing = sorted(en - an) # 预期有、实际没有\n extra = sorted(an - en) # 实际多出来的\n ...\n```\n\n码必须**相等**（不是同档）；名单做**双向集合差**，`missing` / `extra` 分列。整个函数里没有任何计数比较。\n\n## 三 `--must-arms` 原样输出（预期码 / 实际码 / 结果）\n\n```\n# readpath_precheck.py v1.2.0\n#

2。\n\n三条容易被跳过的实现细节：\n\n1. **每臂目录里都放一件已知良好件**。必红臂断言的不只是「红了」，还有「名单里只有该红的那一枚」——不误伤同目录的正例，与「必红」是同一份名单比较同时证明的。\n2. **两条元臂把 `--receipts` 打哑/焊死**：恒返回 0 → `selftest` 必须红在 6 例上（断言 `==1` 的那 6 条）；恒返回 1 → 必须红在 9 例上（断言 `==0` 的那 9 条）。只会红的检查器和永远绿的检查器一样没用，这两条臂是唯一能把这两种坏法抓出来的地方。\n3. **串线臂有两条**：`crosswire-wrong-code` 把预期码写成 0；`crosswire-wrong-name` 把预期名单换成**同样 1 项、但名字不同**的一枚 —— 后者专门用来证明比较器比的是**名字**不是**条数**：任何只比计数的实现都会在这一臂上放行。\n\n## 四 全量回归：1045 帧，前后对照\n\n语料口径：本机 spill 目录里 `*-read_metaweb_pins_batch.txt` 按 mtime 取最早的 **1045** 份（截止 `2026-11-13T10:05:03`，与方法件写作时的 1045 一致；此后新写入的 9 份（10:06–10:14）单列另跑）。合计 23,604,747 字节、1049 条帧记录（4 份文件各含 2 帧）。\n\n| 闸 | v1.1.2 | v1.2.0 | 名单集合差 | 报文 |\n| --- | --- | --- | --- | --- |\n| `--receipts` | exit 1，FAIL **9** 枚 | exit 1，FAIL **9** 枚 | **∅**（missing ∅ / extra ∅） | stdout 逐字节相同 |\n| `--align`（1045 份自证清单） | 1045/1045 exit 0 | 1045/1045 exit 0 | **∅** | — |\n| `--splice`（1045 份自对照） | 983 绿 / **62** 红 | 983 绿 / **62** 红 | **∅** | 逐条相同 |\n| `--selftest` | 28/28 PASS | 28/28 PASS | 用例级逐条相同 | 新增 `[未验收]` 标记 |\n| 9 份新到件（快照外） | exit 0，0 FAIL | exit 0，0 FAIL | **∅** | stdout 相同 |\n\n`--receipts` 那 9 枚失败帧逐 id 如下（新旧同）：\n\n```\nsession-016500510717/70fac9d4ab01-read_metaweb_pins_batch.txt frame 无法解析回执 JSON\nsession-050353ff1b69/e853722fb025-read_metaweb_pins_batch.txt size-mismatch +

kept-zero\nsession-e4ffdbcdaa66/c2b4b22f178d-read_metaweb_pins_batch.txt pin-count + kept-zero\n```\n\n**逐条解释「它为什么没变」**：唯一的变化是新增了 `sink` 记录点与 `--must-arms` / `--env` 两个新模式，判定分支、正则、取数优先级一个字符都没动。所以这 9 枚不该变；变了就是回归失败。`--splice` 那 62 红同样逐条相同：57 条是「回显含 `[...]` 而回执 tp=0」、5 条是「回显段落数 ≠ returned」（后者与 `--receipts` 的 pin-count 同源，是文件自身不自洽）。这两个数字是**改造前就存在的读数**，不是本次引入的。\n\n需要如实登记的一条旧账：`--splice` 的 `[...]` 判据在 1045 份**自对照**（回显==落盘）上开了 57 枪。自对照本应全绿，所以这 57 枪是**该判据已知的假阳性家族**（正文里字面出现 `[...]`，不是呈现层裁剪）。本次**不修**——改判定逻辑会制造漂移，越界；它的必红臂（`splice-dots-tp0`）因此只能算「接线正确 + 在真实语料上确实会开火」，不能算「开得对」。\n\n## 五 只证明能接线、不证明有分辨力（(d) 项）\n\n`--corpus-dir` 让每条判据在真实语料上的开火次数可机读（按判据 tag 从 sink 里统计，不另写第二套判定）。1045 帧实测：\n\n| 判据 | 真实开火 |\n| --- | --- |\n| size-mismatch | 2 |\n| pin-count | 7 |\n| kept-zero | 5 |\n| bad-json（无法解析回执 JSON） | 2 |\n| tp-count（len≠min(tpc,12)） | **0** |\n| tp-over-cap（数组 >12） | **0** |\n| tail-omitted-marker | **0** |\n| missing-bytes-written | **0** |\n| no-frame（批读件内无 RECEIPT 帧） | **0** |\n\n合计 16 条判据命中 / 9 枚文件（多判据可同帧）。**下面 5 臂只能靠畸形构造输入触发，真实 1045 帧里从未出现该形状——只证明能接线，不证明有分辨力**：\n\n- `receipts-missing-bytes`（shape=missing-bytes-written，corpus=0）\n- `receipts-no-frame`（shape=no-frame，corpus=0）\n- `receipts-tail-omitted`（shape=tail-omitted-marker，corpus=0）\n- `receipts-tp-count`（shape=tp-count，corpus=0）\n- `receipts-tp-over-cap`（shape=tp-over-cap，corpus=0）\n\n其中 `no-frame` 尤其要盯：它守的是「回执整段丢失」，而真实语料里 1045 份文件**全部**都有 RECEIPT 帧；这条闸在本机从未有机会开火，它的绿不代表回执不会丢。\n\n## 六 一次期望值标错的复盘（必红演练当场抓到的）\n\n第一次跑 `--must-arms`：23 臂 OK、1 臂 MISMATCH。红的是 `selftest-detects-mute-gate`——实际名单比预期**多**一项 `receipt-pin-count`。\n\n查下去：`selftest` 里确实有第 6 条断言 `receipts_check(...) == 1` 的用例（源码 883 行，在我先前手抄的清单里被漏掉了）。**判据没错，是我手数用例时数错了。** 把预期从 5 项改成 6 项后 24/24。\n\n这件事的价值恰在于它是反向的：元臂（把闸打哑，看 selftest 会不会红）**抓到了我自己的漏数**。它不是「臂通过了」，是「臂先红了一次，红得对」。方法件里 b1 记过同一形状——第一遍 4 条 FAIL 的原因是期望值标错，不是尺子坏了；「对照没通过就不报数」比「对照好看」重要。所以这一臂的红必须留住，不能为了好看把预期改成实际。\n\n## 七 环境指纹（header 原样）\n\n```\n# readpath_precheck.py
