+### Judging tiers
+
+Three judging backends serve the same `/v1/systemone` contract, and all three are first-class
+options — but **hosted Jev is the default**: with no config file and no environment, a run uses
+`https://api.typesafe.ai` (and a loopback `baseUrl` — a local model — is priced at $0).
+
+```bash
+jev-browser tier list      # the three tiers: what each is, what it needs, how to start it, its port, its score, its bar
+jev-browser tier status    # what a run would use right now: baseUrl, tier, resolved goal_done bar, endpoint
+jev-browser tier use kev   # one tier's export line and start command (nothing is written unless you add --persist)
+```
+
+The GGUF readout (`node skills/jev-browser/bin/jev-local.mjs`, port 8092) needs no Python and
+serves an Apple Silicon `llama.cpp` server; Kev (`node skills/jev-browser/bin/jev-kev.mjs`, port
+8008) trades a Python venv, a 9.34 GB base and tens of GB of GPU memory for the accuracy tier. The
+tier table with every measured number — scores, latency, disk, memory, each backend's `goal_done`
+bar and the known holes — lives in [SKILL.md](skills/jev-browser/SKILL.md#judging-tiers).

+# 本地后端「真跑一轮」实测：`jev-browser run` 能不能被本地模型驱动完成
+
+目标：回答一个此前从未测过的问题 —— 本地 GGUF 后端（`node skills/jev-browser/bin/jev-local.mjs`）
+除了能回答单次 judge，能不能被 `jev-browser run` 的 code controller 真正驱动，跑完一整轮浏览器任务。
+
+- 机器：M3 Max / 48 GB / macOS 25.6.0 arm64，node v26.9.0，`llama-server` 0.4.0（Homebrew）
+- 后端：本机全本地 `Qwen3.5-4B-Q4_K_M`（registry 默认项），llama-server `:8090` + Jev 契约服务 `:8092`
+- 浏览器：`--backend chrome --headless`（每次 run 独立 profile，可复现）
+- 实测日期：2026-09-24
+- 原始件（15 个 journal、16 项校准探针、39 步请求日志）：`/tmp/jev-local-smoke/`
+- **`skills/**` 与 `docs/**` 之外一行未改：§6 列出的观测/代码层问题只报告、不改动，本次也没有提交任何 commit**
+
+---
+
+## 0. 结论（先说结果）
+
+**能跑完，但不能可靠地「自己判断跑完了」。**
+
+| 问题 | 答案 |
+|---|---|
+| 本地后端能被 `run` 驱动到 `success` 吗？ | **能**：R7 在真实站点（Wikipedia 搜索结果页，64 个可点选项）4 步达成 `status=success`、退出码 0；另有 3 次 1 步达成（example.com / 商品页 / 目录页） |
+| 传输层/契约层有没有坏？ | **没有**：39 个步骤请求全部首次尝试即成功（`attempts` 全为 1）、0 次超时、0 次 422 `LOW_LABEL_MASS`（最低 label_mass 0.870，阈值 0.5） |
+| 15 次 run 的结局 | `success` 4 · `stuck` 8 · `needs_user` 2 · `max_steps` 1（无 `error`、无 `timeout`） |
+| 卡点在哪 | 不是选元素（`click_target`），而是 **`action` 选择** 与 **`goal_done` 语义**：9 个非 `success` 的 run 里，8 个的失败点都是 `action` 把 `stop`/`click`/`wait`/`go_back` 排在正确动作前面，剩下 1 个（R3）是 `type` 结构上没被提供 |
+| `goal_done >= 0.85` 这条终止规则本地能不能用 | **阈值 0.85 是错的值，不是错的问题**：按终止语义（首次越线即 success，§9）**`goal_done >= 0.25`（可用带 0.12–0.28）7/7 正确 success、0 假 success、0 假 stuck**；现行 0.85 只有 4/7 且假 stuck 3 次。逐「步」分类确实不可分（达成 0.058–0.995 vs 未达成 ≤0.111），代码侧替代（实体/环检测）更差（各 4 次假 success） |
+
+判定边界（详见 §8）：
+- **可用**：`judge` 单问、`click_target` 选元素、「当前页面是不是已经是目标状态」这一问；
+- **不可用**：把 `run` 的 `success` 终止交给 `goal_done`（动作型目标会漏判成 `stuck`）、`action` 动作选择（需要填表/输入时几乎必错）、`blocker` 在表单/报价页上的判定（会假 `needs_user`）。
+

+
+## 1. 环境与启动（逐字）
+
+```bash
+# 本地后端（8090 llama-server + 8092 jev 契约服务）；启动器只复用「同一个 gguf」的已启动实例
+node skills/jev-browser/bin/jev-local.mjs
+# → [local] model ready: ~/.jev-browser/models/Qwen3.5-4B-Q4_K_M.gguf (2.6 GiB)
+# → [local] llama-server: /opt/homebrew/bin/llama-server
+# → [local] starting llama-server: ... -m .../Qwen3.5-4B-Q4_K_M.gguf --host 127.0.0.1 --port 8090 -c 16384 -ngl 99 --cache-type-k q8_0 --cache-type-v q8_0 -t 8
+# → [local] llama.cpp serving on http://127.0.0.1:8090 (pid 38548, -c 16384)
+# → [local] serving /v1/systemone on http://127.0.0.1:8092 (qwen3.5-4b-q4-k-m · Qwen3.5-4B Q4_K_M); Ctrl-C to stop
+# → TYPESAFE_BASE_URL=http://127.0.0.1:8092 TYPESAFE_API_KEY=local
+```
+
+模型加载 2.7 s（Metal），服务就绪后 `/health` 返回 `{"status":"ok","service":"jev-local","model":"qwen3.5-4b-q4-k-m"}`。
+
+```bash
+# fixture 站点（tests/fixtures/server.mjs，固定 3111 端口）
+node --input-type=module -e "const {createSite}=await import('./tests/fixtures/server.mjs');const s=createSite();await new Promise(r=>s.server.listen(3111,'127.0.0.1',r));"
+```
+
+每次 run 的环境（覆盖仓库外的 user config，不写仓库）：
+
+```bash
+export TYPESAFE_BASE_URL=http://127.0.0.1:8092 TYPESAFE_API_KEY=local
+export JEV_BROWSER_CONFIG=/tmp/jev-local-smoke/config-<name>.json   # journalDir + chrome.userDataDir 指向 /tmp
+node skills/jev-browser/bin/jev-browser.mjs run --goal "<goal>" --url <url> \
+  --backend chrome --headless --max-steps <8|5|6> --json
+```
+
+`--max-steps` 全部取 4–8；`timeoutMs` 保持**默认 20000**（除 M 组 2 次刻意放大，见 §5 注）。
+退出码：`success=0`、`needs_user=3`、其余 2（`bin/jev-browser.mjs:132-134`）。
+
+---
+
+## 2. 各次 run：目标、结局、步数、墙钟、停在哪
+
+`steps` = controller 真正执行的动作数（`memory.history.length`）；`needs_user`/首步 `stop` 会是 0 步但已花掉 1 次 judge。
+
+| # | goal（简写） | 站点 | 状态 | 退出码 | steps | 墙钟 | in-app | 停在哪 |
+|---|---|---|---|---|---|---|---|---|
+| R1 | 确认主标题是 "Example Domain" | example.com | **success** | 0 | 1 | 9.1 s | 5.9 s | step1 `goal_done=0.992` |
+| R2 | 把 Red Gadget 加入购物车 | fixture /products | stuck | 2 | 1 | 10.1 s | 7.8 s | step2 模型选 `stop`（`goal_done=0.057`），实际只差一次点击 |
+| R3 | DDG 搜 python → 打开 python.org | duckduckgo.com | stuck | 2 | 4 | 59.1 s | 56.1 s | step5 模型选 `stop`；全程**没机会输入**（§6.1） |
+| R4 | 打开 Docs 并点按钮显示密码 | fixture / | stuck | 2 | 4 | 31.4 s | 26.6 s | step5 模型选 `stop`，**目标其实第 2 步就达成了** |
+| R5 | 点 Accept 关掉 cookie 弹窗 | fixture /consent | stuck | 2 | 1 | 16.3 s | 12.6 s | step2 模型选 `stop`，**目标第 1 步已达成** |
+| R6 | 从搜索结果打开 python.org | duckduckgo.com/?q=… | **needs_user** | 3 | 0 | 29.5 s | 26.1 s | step1 `blocker=verification_challenge(0.973)` —— **真阳性**（DDG 出人机验证，§4） |
+| R7 | 打开 Alan Turing 条目 | en.wikipedia.org Special:Search | **success** | 0 | 4 | 46.4 s | 45.2 s | step4 `goal_done=0.995`（state 65 个元素 / 64 个可点选项里点对 `e20`） |
+| R8 | 搜 Wikipedia → 打开条目 | en.wikipedia.org Main_Page | max_steps | 2 | 8 | 96.4 s | 94.8 s | 8 步用尽，末次校验 `goal_done=0.005` |
+| p1 | 确认商品页已打开并显示价格 | fixture /products/red-gadget | **success** | 0 | 1 | 5.5 s | 4.5 s | step1 `goal_done=0.982` |
+| p2 | 确认目录页已打开 | fixture /products | **success** | 0 | 1 | 4.4 s | 3.5 s | step1 `goal_done=0.988` |
+| p3 | 给 Team 套餐开免费试用 | fixture /pricing | **needs_user** | 3 | 0 | 5.5 s | 4.7 s | step1 `blocker=missing_information(0.684)` —— **假阳性**，§4 |
+| p4 | 用给的邮箱/密码登录 | fixture /login | stuck | 2 | 3 | 17.1 s | 16.2 s | 连续 3 次无变化动作；**全程没输入**（§5） |
+| g1 | 把 Red Gadget 加入购物车（商品页起步） | fixture /products/red-gadget | stuck | 2 | 0 | 6.0 s | 6.0 s | step1 模型选 `stop(0.43)`，页面正中间就是 "Add to cart" |
+| g3 | 点按钮显示密码并确认可见 | fixture /docs | stuck | 2 | 1 | 9.6 s | 9.6 s | step2 模型选 `stop`，**目标第 1 步已达成**（`goal_done=0.329`） |
+| g4 | 填联系表单并发送 | fixture /contact | stuck | 2 | 0 | 8.3 s | 7.2 s | step1 模型选 `stop(0.30)`，四个字段的值都已提供 |
+
+补充：
+- R6 / p3 的 `steps=0` 但 journal 里有一条 step1 —— 判定发生在动作之前，`steps` 只数动作。
+- R6、p3 的 `handOff` 均为 `null`；`resume` 里只有 `{backend,cdpUrl,targetId}`，没有 `spaceId`。CLI 仍会打印
+  “the browser was handed to you; resume with --space-id …”（`bin/jev-browser.mjs:128`），而 chrome 后端在
+  `success=false` 且 headless 时会关掉浏览器（`lib/backends/chrome.mjs:406`）—— 这条 `needs_user` 提示对 chrome 无意义（§6.4）。
+
+### 2.1 逐 run 归因（journal `steps.jsonl` + `requests.jsonl`）
+
+| run | 归因 | 依据 |
+|---|---|---|
+| R1 / p1 / p2 / R7 | **无问题**（正常终止） | R7 由 `goal_done=0.995` 收尾；其余 3 次首步 `goal_done≥0.982` |
+| R2 / g1 | **模型误判（action）** | 商品页 `action=stop(0.43/0.32)`，而 `click_target` 的第一名就是页面正中的 `button 'Add to cart'`；元素不缺、也没报错 |
+| g4 | **模型误判（action）** | 联系表单页，4 个字段的值都在 `inputs` 里，`editable` 4 个、`type` 在 `allowedActions` 内，`action` 仍选 `stop(0.30)` |
+| R4 / R5 / g3 | **模型误判（goal_done 语义）** | 动作本身做对了（R4 第 2 步、R5 第 1 步、g3 第 1 步的目标均已达成，见 `finalTextExcerpt`），但 `goal_done` 只有 0.281/0.586/0.329（<`goalDoneFinal` 0.7）→ 记 `stuck` |
+| p4 | **模型误判（action 排序）** | `action` 四选一里 `type` 垫底（0.105），虽然 `type_target`=Email(0.851)、`type_value`=email(0.933) 都对；controller 按模型序执行 ⇒ 3 次无变化 |
+| R8 | **模型误判 + controller 放大** | `type` 已提供（100 元素/99 可点/1 可编辑，`allowedActions` 含 `type`）却没被选；controller 的 progress 规则又两次选了走不通的 `go_back`（`no previous page in history`） |
+| R3 | **证据缺口（missing evidence）** | `<input role="combobox">` 在观测里不是 `editable`（§6.1，dry-run 实测 `editable=0`），`type`/`type_target`/`type_value` 三问根本没生成 ⇒ 模型只能在 click/scroll/wait/stop 里挑 |
+| p3 | **模型误判（blocker 假阳性）** | 定价页给出 `missing_information(0.684)`；页面三个套餐与按钮都列在元素表里，`inputs` 也不缺 |
+| R6 | **真阳性，但 run 无事可做** | DDG 返回人机验证（`visible_text` 逐字可查），`verification_challenge(0.973)` 判对了；这次没有可自动化空间 |
+| — | **API 失败：0 次** | 39/39 请求 `status=succeeded`、`attempts=1`；无 `TIMEOUT`/`LOW_LABEL_MASS`/`CONNECTION` |
+| — | **后端/driver 异常：0 次** | 无 `error` 状态、无 Chrome 启动失败；唯一反复出现的 `no previous page in history` 是 controller 主动 `go_back` 后被 driver 正确拒绝（§6.3） |
+
+---
+
+## 3. 逐步延迟画像（39 个步骤请求，全部取自 `requests.jsonl`）
+
+单步 = 一次 HTTP 批次调用里本地 provider 顺序跑完该步的所有问题；`prompt_tokens` 是**未命中前缀缓存、真正需要重算**的 token（`timings.prompt_n`）。
+
+| 指标 | p50 | mean | max |
+|---|---|---|---|
+| 单步请求（客户端观测） | **4,312 ms** | 5,984 ms | **18,151 ms** |
+| 本地服务 `ms_total` | 4,310 ms | 5,978 ms | 18,147 ms |
+| 单步 prompt tokens（去缓存后） | 3,555 | 4,680 | 12,254 |
+| 单步问题数 | 5 | 5.6 | 8 |
+
+按问题拆（同一批内，第一问承担 state 预填充，其余问题命中 llama.cpp 前缀缓存）：
+
+| 问题 | n | p50 | mean | max | prompt p50 | cold/warm | label_mass p50 / min |
+|---|---|---|---|---|---|---|---|
+| `goal_done` | 39 | **1,165 ms** | 2,317 ms | 8,887 ms | 933 | 29/10 | 0.966 / 0.939 |
+| `blocker` | 38 | 725 ms | 737 ms | 953 ms | 559 | 1/37 | 0.995 / 0.990 |
+| `click_target` | 38 | 713 ms | 1,373 ms | 4,499 ms | 490 | 0/38 | 0.992 / 0.926 |
+| `progress` | 23 | 606 ms | 587 ms | 771 ms | 442 | 0/23 | 0.995 / 0.984 |
+| `action` | 38 | 595 ms | 606 ms | 798 ms | 464 | 0/38 | 0.985 / 0.870 |
+| `select_target` | 7 | 568 ms | 547 ms | 721 ms | 362 | 0/7 | 0.962 / 0.932 |
+| `submit_after_type` | 12 | 567 ms | 596 ms | 807 ms | 465 | 0/12 | 0.990 / 0.977 |
+| `type_target` | 12 | 547 ms | 596 ms | 1,013 ms | 433 | 0/12 | 0.983 / 0.971 |
+| `type_value` | 12 | 546 ms | 553 ms | 748 ms | 418 | 0/12 | 0.977 / 0.968 |
+
+结论与既有文献的两点修正：
+
+1. **`click_target` 不再是最贵的**。`experiments/gguf-provider/RESULTS.md` 里 “click_target 6.1 s、整步 9 s（热）/18.3 s（冷）”
+   是在**不命中前缀缓存**的口径下量的；真实 run 里 provider 顺序发问，state 只算一次（`goal_done` 那一问承担，
+   p50 1.2 s、max 8.9 s），后面每一问只付「问题块」的增量（400–500 tok，0.5–0.7 s）。整步 p50 落在 **4.3 s**。
+2. **但默认 20 s 客户端超时是真的紧**。R8 step8 的状态是 12,254 tok，单步 **18,151 ms**，距 `timeoutMs=20_000`
+   只剩 **1.85 s**；`lib/typesafe.mjs:201-207` 的超时标 `retryable`，一旦触发会把整批 5–8 问重跑（最多 3 次），
+   本次 15 次 run 没有触发，但更大页面/更慢机型会踩。39 步里 0 次超时、0 次 `LOW_LABEL_MASS`。
+
+---
+
+## 4. `goal_done` 分离分析：有没有一条阈值能分开「已达成 / 未达成」
+
+数据两部分：(a) **首步校准探针 16 项**——用 skill 自己的 `run --dry-run` 构造第一步 state（含 goal/inputs/page），
+只把 `goal_done` 这一问发给本地服务，真值由页面构造决定；(b) **15 次 run 的 39 个步骤判定**，真值由 journal + 最终页面人工判定。
+
+### 4.1 首步校准（16 项，state 与 controller 实际发送的完全一致）
+
+| id | 真值 | goal_done | id | 真值 | goal_done |
+|---|---|---|---|---|---|
+| T1 商品页已打开 | 达成 | **0.981** | F1 加入购物车 | 未达成 | 0.008 |
+| T2 目录页已打开 | 达成 | **0.988** | F2 登录成功并看 dashboard | 未达成 | 0.007 |
+| T3 联系表单在页面上 | 达成 | **0.954** | F3 Team 试用已开始 | 未达成 | 0.008 |
+| T4 登录页在问邮箱密码 | 达成 | **0.969** | F4 已显示密码 | 未达成 | 0.032 |
+| T5 三个套餐已列出 | 达成 | **0.987** | F5 弹窗已关闭 | 未达成 | 0.096 |
+| T6 页面说需要管理员权限 | 达成 | **0.936** | F6 已打开定价页且 $29 | 未达成 | 0.011 |
+| T7 页面在问 cookie 同意 | 达成 | **0.839** | F7 已打开 Docs | 未达成 | 0.043 |
+| T8 主标题 Example Domain | 达成 | **0.997** | F8 已从链接打开 IANA | 未达成 | 0.036 |
+
+**达成 0.839–0.997（n=8）；未达成 0.007–0.096（n=8）。最大负例 0.096 ≪ 最小正例 0.839，中间是一段空档。**
+即「这页是不是已经是目标状态」这一问，本地 4B 是可用的；官方阈值 0.85 只有 1/8 真例踩线落空（T7 = 0.839），
+0/8 假阳性。任何落在 **[0.10, 0.83]** 的阈值都能把这 16 项全部分开。
+
+### 4.2 run 内的判定（含「做了一步之后」的状态）——分离失效
+
+| 类别 | 样本（goal_done） |
+|---|---|
+| 未达成，首步 | R2 .008 · R3 .004/.011/.012/.006/.006 · R4 .010 · R5 .096 · R6 .005 · p3 .008 · p4 .010 · R7 .023/.015/.014 · R8 .003/.022/.015/.009/.009/.008/.010/.011（+末次 .005）· g1 .050 · g3 .027 · g4 .012 |
+| 未达成，但**做了一步**（最危险的一档） | **R4 step2 = 0.111** |
+| 已达成，且是首步就能判 | R1 .992 · p1 .982 · p2 .988 |
+| 已达成，**靠动作达成** | R7 step4 **.995** · R5 step2 **.586** · g3 step2 **.329** · R4 step3 **.273** · R4 step5 **.281** · **R4 step4 = 0.058** |
+
+- 未达成侧最大 **0.111**（R4 step2，点了按钮但页面刚变）；已达成侧最小 **0.058**（R4 step4，同一页、密码已可见）。
+  **两个区间重叠 ⇒ 不存在能把「已达成 / 未达成」分开的阈值。**
+- 这不是「阈值调低一点就行」：把阈值放到 0.2 能救回 g3(0.329)/R4(0.273)，但会救不回 R4 step4(0.058)，而
+  同一页 step2 的 0.111 又高于它 —— 判定顺序本身不稳定（同页同目标：0.111 → 0.273 → 0.058 → 0.281）。
+- 反过来说，`goal_done` 在「页面本身就是答案」的场景（R1/R7/p1/p2、T1–T8）非常干净，0.98 上下；
+  **它坏掉的正是「做完一个动作之后」这一类**——4B 对「动作产生了结果」的确认能力不足。
+
+### 4.3 对控制器的直接后果
+
+- `goal_done >= 0.85`（`lib/config.mjs:27`）在动作型目标上**永远不会触发**：本次 6 个「已达成」样本里 5 个 < 0.85。
+- 于是 run 只能靠 `stop` 分支收尾，而 `stop` 只有在 `goal_done >= goalDoneFinal(0.7)`（`lib/config.mjs:28`）时才记 `success`：
+  R4(0.281)、R5(0.586)、g3(0.329) 三个**实际已经完成**的 run 被判 `stuck`，退出码 2。
+- 末次校验（`maxSteps` 用尽后补问一次）用的正是同一个 0.7：R8 得 0.005，判 `max_steps`（这次判对了）。
+- **所以「本地后端能不能跑完」与「本地后端能不能承认自己跑完」是两件事**：前者可以（R7），后者不可信。
+
+---
+
+## 5. `action` 选择：与页面明显允许的动作不符
+
+按严重度排序（全部有 journal 逐字证据）：
+
+1. **p4（登录页）——模型知道该填哪儿、填什么，就是不选「type」。** 同一 state 的完整判读（`/tmp/jev-local-smoke/login.dryrun.json` 重放，确定性复现）：
+   ```
+   action         click 0.430 · stop 0.246 · wait 0.220 · type 0.105     ← 四选一里 type 垫底
+   type_target    e2 (Email)  0.851   ← 正确
+   type_value     email       0.933   ← 正确
+   click_target   e4 ("Sign in" 按钮) 0.892
+   submit_after_type  0.183（= "不按回车"，也对）
+   ```
+   controller 按模型动作序建候选（`lib/controller.mjs:263` 的 `for (const [action] of decision.actions)` → `:320-323` 的取候选），于是先挑 `click e4`（空表单，无变化），
+   再挑 `wait`（无变化），第三个才轮到 `type` —— 3 次无变化后 stuck（`noChangeLimit=3`）。
+2. **R3（DDG 首页）/ R8（Wikipedia 主页）——同样从不输入**：R3 依次点了搜索框 combobox、Search 单选、"
+   Set As Default Search" 链接；R8 点了 Search 按钮、搜索框 combobox、滚屏、返回，最后点进一篇无关条目
+   （Hashim Thaçi）。两者原因不同：R3 的 `type` 是**结构上就没被提供**（§6.1）；R8 的 `type` 提供了
+   （Main_Page dry-run：100 个元素 / 99 个可点 / 1 个可编辑，`allowedActions=click,type,scroll_down,wait,stop`，
+   `type_target`/`type_value`/`submit_after_type` 三问齐全，`inputKeys=[query]`）却没被选。
+3. **提前 `stop`（3 次）**：g1/g4 在「页面正中就是 Add to cart / 四个字段都已给值」时第一问就选 `stop`
+   （0.43 / 0.30）；R2 在商品页选 `stop`（0.32）。`action` 的 confidence 只有 0.06–0.13（无信心），
+   但 controller 不用 confidence 做弃权（`lib/typesafe.mjs:57` 归一化后只给 `confidence` 字段，无人消费）。
+4. **R7 的 `go_back` 空转**：第 1–2 步 `action` 把 `go_back`(0.28) 排在 `click`(e20 = 正确的 Alan Turing 链接) 前面，
+   白走两步（`go_back` 的 `click_target` 一直是 e20 —— 选元素没问题，选动作有问题）。
+   第 2 步 `go_back` 失败（`no previous page in history`）。
+5. **R8 的重复无效 `go_back`**：step5/7/8 由 controller 的「progress 退化」规则（`lib/controller.mjs:257-261`）
+   自己选了 `go_back`，其中两次报 `no previous page in history`；因为 blocked 记忆的键是
+   `${stateHash}|${actionKey}` 而 state 每步都变（含 `previous_page`/`last_action`，`lib/controller.mjs:193-196`），
+   同一台不可能完成的动作被反复重试。
+
+对照：**`click_target` 是本次最稳的一环**。R7 在 65 个元素的真实页面上，每一步都把正确条目排在第一
+（`e20 = link 'Alan Turing' → /wiki/Alan_Turing`，0.784 / 0.742 / 0.713；第二名 `e22` 是同一个 `/wiki/Alan_Turing` 的另一处链接，
+0.17 / 0.22 / 0.25，两者合计 0.95 —— 即使第一名失手，结果页也是对的）；R2 step1、R4 step1/2、R5 step1、g3 step1 在 fixture 上也都点对。
+RESULTS.md 里 “`action + click_target` 5 题只对 2 题” 的短板，在真机 run 里重现的是其中的 **action 半边**。

+
+## 6. 观测/代码层问题（只报告，未改任何 `skills/**` 文件）
+
+> **状态更新 2026-09-24 ~01:25（本次 run 之后，工作区并发改动、未提交）**：6.1（combobox 不是 textbox）、
+> 6.4（`needs_user` 的 ego 专属提示）、6.5（本地 token 按 hosted 价格计费）三条**已在 `skills/**` 里被修**：
+> `lib/observe.mjs` 新增 `isComboboxField()` + `tests/e2e/combobox.test.mjs`；`bin/jev-browser.mjs` 的 `needs_user`
+> 分支改为有 `spaceId` 才提示 `--space-id`，否则说明浏览器已关闭；`lib/typesafe.mjs` 新增
+> `isLoopbackBaseUrl()`/`pricePerMtokFor()`，loopback 计费为 0。6.2/6.3/6.6 未被改动。下面保留的是
+> **实测时的行为**（run 时间 00:54–01:08），行号按当时的工作区版本。
+
+### 6.1 `role="combobox"` 的 `<input>` 被当成非文本字段 → 永远没有 `type` 动作
+
+> **状态更新 2026-09-24 ~01:25**：本条已被并发修复（工作区未提交）—— `lib/observe.mjs` 新增 `isComboboxField()`，
+> 把 `role=combobox` 的 `<input>/<textarea>/[contenteditable]` 归为 `textbox`，并加了 `tests/e2e/combobox.test.mjs`。
+> 下面描述的是**本次全部 run 所测的修复前行为**（run 时间 00:54–01:08），保留作为 §5 中 R3 的成因记录。
+
+`lib/observe.mjs:40`：只要元素带 `role` 属性就原样采用（`if (role) return role.toLowerCase();`），
+`lib/observe.mjs:134` 只有 `role === "textbox"` 才置 `editable`；`lib/questions.mjs:88` 又要求
+`editable.length && inputKeys.length` 才把 `type` 放进 `allowedActions`。
+
+DDG 首页/结果页的搜索框是 `<input role="combobox">`（ARIA 1.2 组合框写法）→ 观测里是
+`combobox 'Search with DuckDuckGo'`、`editable` 计数 **0**，`action` 选项只剩 `click,scroll_down,wait,stop`，
+`type_target/type_value/submit_after_type` 三问根本不生成。**R3「不会输入」不是模型的错，是证据缺口。**
+对照：Wikipedia 的搜索框把 `role=combobox` 放在**外层容器**上，`<input>` 自身是 `textbox` → 观测正常
+（`text field 'Search Wikipedia' (type search, …)`），fixture 的 `<input id="q">` 同样正常。
+这里**不需要看本地模型**：hosted Jev 在 DDG 这样的站点上也会失去 `type` 选项。
+
+### 6.2 候选动作顺序 = 模型动作序，`type` 排后面就永远到不了
+
+`lib/controller.mjs:264-323`：候选完全按 `decision.actions`（模型概率序）展开，`open.find(c => !tried.has(...))`
+取第一个没试过的非 `stop` 候选。p4 里 `click → wait → type`，于是在 `click`/`wait` 都试废之前，正确的 `type`
+不会被尝试（3 次无变化直接 stuck）。`type` 没有任何「信息增益优先」的加成，也没有用 `actionConfidence` 做弃权。
+
+### 6.3 失败动作不会被记住
+
+`lib/controller.mjs:193-196` 的 `blocked` 键含 `stateHash`，而 state 每步都变（`previous_page`、
+`last_action` 参与），所以「driver 明确报错」（如 `no previous page in history`）的动作会在下一步换个 hash 后重来。
+R8 里连续两次白跑。真正需要的是「动作种类级」的失败记忆，而不是 (状态 × 动作) 级。
+
+### 6.4 `needs_user` 在 chrome 后端不可执行
+
+R6/p3：`handOff: null`、`resume` 无 `spaceId`，且 headless 下浏览器已被关掉（`lib/backends/chrome.mjs:406`
+`keepPage = keep ?? (success && chrome.keepOnSuccess !== false && !headless)`），而 CLI 提示语仍是 ego 专属的
+“the browser was handed to you; resume with --space-id …”（`bin/jev-browser.mjs:128`）。这次 R6 是**真**拦住
+（人机验证），用户按提示去接管时会发现没有浏览器可接。
+
+### 6.5 本地 run 的 `costUsd` 是假的
+
+`lib/runner.mjs:61` 把 `config.pricePerMtok`（默认 0.042 美元/Mtok）传给客户端，`lib/typesafe.mjs:150` 照此
+对本地 token 记账：R8 报 `costUsd=0.002705`。本地 token 实际 $0。只影响显示与 `budgetUsd` 预算判断（本次最贵的
+R8 也只有 0.0027 ≪ 0.25，没触发）。
+
+### 6.6 `steps` 与 `usage.requests` 不是一回事
+
+`needs_user`/首步 `stop` 的 run 报 `steps: 0` 但已消耗 1 次请求（R6、p3、g1、g4）；`max_steps` 的 run 最后一次
+校验请求不在 `steps` 里（R8：8 步 / 9 请求）。读 journal 时不要拿 `steps` 当「问过几次」。
+

+## 7. 复现
+
+```bash

+
+注：DDG 在本机 + headless 下会返回**人机验证**（“Unfortunately, bots use DuckDuckGo too. … Select all squares
+containing a duck: Submit”，见 `r6.dryrun.json` 的 `visible_text`），所以「搜索结果页 55 选项」这一族没能用 DDG 测，
+改用 Wikipedia 搜索结果页（65 个元素 / 64 个可点选项，`wiki.dryrun.json`）。R6 的 `needs_user` 因此是**真阳性**。
+
+---
+
+## 8. 判定：本地后端哪些用法安全、哪些不安全
+
+**安全（有数据支撑）**
+1. `jev-browser judge` / `pick` 单问或多问一批 —— 39 步 0 失败、0 低 label_mass，整步 p50 4.3 s、$0。
+2. **「当前页面是不是已经是目标状态」** 这一问：首步 8/8 真例 ≥0.839、8/8 负例 ≤0.096，阈值 0.85 只有 1 次踩线。
+   适合做「打开某页 → 确认到达」这类只读型目标（R1/p1/p2 都是 1 步 success）。
+3. **`click_target` 选元素**：64 个可点选项的真实页面上每一步都选对；小 fixture 上同样对。
+
+**不安全（有数据支撑）**
+1. **`goal_done` 的阈值 0.85 在本地偏高**（细节与计分见 §9）：按「第一次越线即 success」的终止语义，
+   **0.25（可用带 0.12–0.28）得到 7/7 正确 success、0 假 success、0 假 stuck**；0.85 得到 4/7，假 stuck 3 次
+   （R4/R5/g3，均已实际完成）。**不要**用代码侧规则替代它（实体匹配、环检测各产生 4 次假 success，聚合无增益）。
+   注意：逐「步」分类确实不可分（§4.2），能分的是「一条 run 里第一次越线的那一步」。
+2. **`action` 动作选择**：四选一里正确的 `type` 被排到末位（0.105 vs click 0.430），3 次 run 全程未能输入；
+   另有 3 次在「明显该点/该填」的页面上第一问就选 `stop`。要跑通表单/搜索类任务，必须在 controller 侧加
+   信息增益优先或 confidence 弃权，而不是指望调 prompt。
+3. **`blocker` 在「有内容可操作」的页面上**：p3 在 fixture 定价页给出 `missing_information(0.684)` → 假 `needs_user`；
+   另有 2 次擦边（R4 step2 `missing_information` 0.368、R5 step1 `consent_or_permission_dialog` 0.393，都是 0.6 阈值下的
+   第二名）。真阳性只有 1 次（DDG 人机验证 0.973）。即：**`needs_user` 的中断结论在本地不可当回事**。
+4. 传输层边界：单步 18.2 s（12.2k tok）对默认 20 s 超时只剩 1.85 s，更大页面会触发可重试超时并把整批重跑最多 3 次。
+
+---
+
+## 9. 终止规则回放：哪条规则能让本地 `run` 正确地报 `success`
+
+离线回放，无新浏览器 run；模型调用只用已保存的 state（§9.4）。脚本 `/tmp/jev-local-smoke/rules.mjs`（纯离线，只读 `steps.jsonl`）。
+
+### 9.1 计分口径（严格）
+
+- journal 第 N 行的页面是第 N 步动作**之前**看到的页面；真值逐 (run, step) 标注：39 步里 **9 步是达成页**
+  （R1 s1、R4 s3/s4/s5、R5 s2、R7 s4、p1 s1、p2 s1、g3 s2）。
+- **正确 success**：规则触发的那一步，页面本身已经满足目标。
+- **假 success**：在未达成的页面上触发 —— 因为 run 会在动作之前停下，目标永远不会被达成。**一次即否决该规则。**
+- **漏报 success（= 假 stuck）**：该 run 出现过达成页，但规则从未触发。
+- **正确 stuck**：该 run 从未出现达成页，规则也从未触发。
+
+### 9.2 结果（`!` = 触发在未达成页上；`-` = 未触发）
+
+| 规则 | 阈值 | 正确 success | 假 success | 假 stuck | 正确 stuck | 各 run（触发步） |
+|---|---|---|---|---|---|---|

+
+### 9.3 赢家：把阈值从 `0.85` 降到 **0.25**（可用带 0.12–0.28），规则本身不用动
+
+- **7/7 正确 success、0 假 success**；对照现行 0.85 的 4/7 正确 + 3 个假 stuck（R4/R5/g3）。
+- 触发点全部落在达成页上：R1 s1(0.992)、R4 s3(0.273)、R5 s2(0.586)、R7 s4(0.995)、p1 s1(0.982)、p2 s1(0.988)、g3 s2(0.329)。
+- 8 个从未达成的 run 一次都没触发 → 8 个正确 stuck。
+- 两个边界：可用带下沿 **0.12** 距最高的未达成读数 **0.111**（R4 s2）只有 1.08×；8 个未达成 run 内部的最高读数是
+  **0.057**（R2 s2），距 0.25 有 4.4×。所以下沿受「动作前的那一步」约束，不是受未达成 run 约束。
+- 聚合没有帮助：全局 max / max-of-last-3 与单次读数同分（只是把可用带整体平移，低阈值下同样会早触发）；
+  **median-of-last-3 反而把 R7 的 0.995 尖峰抹平 → 漏报 1 次**，并且没有可用带。
+- 代码侧规则不能替代判据：**实体匹配 4 次假 success**（R2:2、R4:2、R7:1、g1:1 —— 其中 R2/g1 是整个 run 从未达成，
+  最坏的一类：搜索结果页 URL/title 里回显查询词、商品页 URL 里就有商品名）；**环检测 4 次假 success**，
+  并且若把它当 stuck 用会掐掉 R7（正是那个能成功的 run）。
+- 与代码侧组合：`阈值≥t AND 上一步有变化` 与纯阈值同分（空操作）；`AND 实体` 会漏掉 g3；`OR 实体` 立刻产生 4 次假 success。
+
+### 9.4 规则 2（去掉 volatile conditioning）：前提不成立，**不要为此改代码**
+
+journals 不保存 state 对象（只有 url/title/elementCount/targets/各问答案），所以「把 `last_action`/`previous_page`
+从真实步骤里删掉再问」无法离线回放。可做的是两侧合围，结论一致：
+
+- **同页同目标、条件不同的真实读数**（journal 内的同页分组）：
+  - R4 `/docs` 四步 **0.111 / 0.273 / 0.058 / 0.281 → spread 0.223**（页面内容相同；密码在第 2 步之后一直是可见的）；
+  - p4 `/login` 三步 0.010 / 0.035 / 0.011 → spread 0.025；R8 Main_Page 四步 spread 0.008；R3 DDG 首页 spread 0.006。
+- **固定页面 + 合成 conditioning**（6 个已保存 state × 5 种条件 =「无 conditioning + 4 种 `last_action`」，30 次判读）：
+  spread 最大 **0.057**（contact 页 0.012→0.066），最小 0.004；换一个**不同页面**当 `previous_page`
+  （6 次判读）swing ≤ 0.033。即 volatile 块本身最多移动 ~0.06。
+- **真实 post-action 配置重放**（页面不变，conditioning 用 journal 里那一步的真实 `last_action` + `previous_page`）：
+  p4 s2 journal 0.035 = 重建 0.035（重建保真）/ 去 conditioning 0.010；p4 s3 0.011 / 0.009 / 0.010；
+  R3 s2 0.011 / 0.012 / 0.004；R3 s4 0.006 / 0.008 / 0.004；R7 s2 0.015 / 0.014 / **0.029**；R7 s3 0.014 / 0.016 / **0.029**。
+  → 去 conditioning 在 6 个可重放的 post-action 配置上把读数移动最多 **0.025**（p4 s2：0.035→0.010；其余 ≤0.015），全部仍远低于任何阈值；**不会新增假 success**。
+- 结论：**R4 那个 0.223 的同页波动不是 conditioning 造成的**（conditioning 只能解释 ≤0.06），而是「动作之后这一页本身」
+  被判低 —— 这与 §4 的判断一致。去掉 conditioning 既不修 R4/R5/g3，也不引入假 success，属于**空操作**，
+  不要为它改 `controller.mjs`。要真正验证 met 侧的这条假设，必须先让 journal 存下 state。
+- 保真度校验：把已保存 state 去掉 conditioning 后重放，读数与 journal 首步几乎逐位一致
+  （R3 .004/.004、R6 .005/.005、R7 .029/.023、R8 .003/.003、p4 .010/.010）→ 该实验的测量本身可信。
+- 模型用量：本次全部判读 **~60 s** 推理（共 67 次 goal_done：校验 5 + 真实 post-action 14 + 合成 conditioning 30 + 换 previous_page 18），远低于 20 min 预算。
+
+### 9.5 覆盖与掉队声明
+
+- 15 个 run、39 步全部进入回放，**没有丢弃任何 run**。
+- 3a 的实体是人工从 goal 里挑的（真实实现需要抽词器）；R5/p2/g4 这类 goal 没有实体 → 该规则在它们身上只能不触发，
+  这已经计入表里的「假 stuck」。
+- 9.4 里 **R8 s2 一行作废**：那一步的页面是 `/w/index.php?search=&title=Special%3ASearch`，与已保存的 Main_Page state 不是同一页
+  （journal 的分组把两者混在一起），该行已从结论中剔除。
+- 9.4 无法覆盖的：**任何「达成页 × 动作之后」的 state**（R4 s3/s4/s5、R5 s2、g3 s2 的页面都没有被保存）——
+  这正是规则 2 唯一需要的那一格。
+
+### 9.6 SKILL.md 该改成什么
+
+`skills/jev-browser/SKILL.md` 现在的句子（第 166–176 行）：
+
+> …but the `goal_done >= 0.85` rule that prints `success` cannot be trusted for a goal that needs an action:
+> … so the two bands overlap and **no threshold separates them**. `0.85` therefore never fires for an action goal,
+> runs that had actually finished were reported `stuck` … unless the termination rule stops relying on `goal_done`
+> (a rule over the final URL and title would do).
+
+建议替换为（事实依据：§9.2/§9.3）：
+
+> …but the value `0.85` is wrong for this backend, not the question. Scored as a termination rule (first step whose
+> reading crosses the line), `goal_done >= 0.25` — any value in 0.12–0.28 — called **every one of the 7 runs that did
+> reach the goal** a success **at a page that already showed the goal**, and never fired on the 8 runs that never got
+> there: 7 correct successes, 0 false successes, 0 false `stuck` (the shipped 0.85 gave 4 / 0 / 3). Do not replace
+> `goal_done` with a code-side rule: "the goal's named entity appears in the final URL or title" false-fired on 4 runs
+> (2 of them never completed — search URLs echo the query, product URLs contain the product name), loop detection
+> false-fired on 4, and aggregating the last readings (max/median of 3) never beat the single reading — the median
+> even lost the one run whose success was a single 0.995 reading. The volatile `last_action`/`previous_page` in the
+> state are *not* the problem (measured effect <= 0.06): do not add code to strip them. Locally, use 0.25 on both the
+> per-step check and the final check; `0.85` remains right for hosted Jev.
+
+（`config set thresholds.goalDone 0.25` / `thresholds.goalDoneFinal 0.25` 就是实现；本文件不改 `skills/**`。）

+# 本地 GGUF 兜底探针（未训练 sub-1B + llama.cpp 首 token logprob）——**负结果**
+
+**问题**：能不能「零训练、零 Python、零额外权重」，只用一个**未训练**的 sub-1B GGUF 加
+llama.cpp 的「首 token 选项标签 logprob」读法，把本 skill 的 `POST /v1/systemone`
+（`noul` / `choice` / `score`）答出来，作为可随 skill 分发的本地兜底？
+
+**裁定：不能（NO）。** 机制通路全部成立（HTTP 契约、标签单 token 校验、延迟都在可接受范围），
+但两个候选模型的答案等于或**低于**「永远选第一个选项」的平凡策略，且所有行为证据都指向同一个结论：
+它们没有在读选项内容。
+
+| 决定性证据 | 数字 |
+|---|---|
+| 0.6B 总准确率 vs 平凡基线 | **11/20 = 0.55** vs 基线 **11/20 = 0.55**（同分；两者在 16/20 题上答案相同） |
+| 0.8B 总准确率 vs 平凡基线 | **10/20 = 0.50**（低于基线；两者只在 13/20 题上相同，偏差 2 次对、5 次错） |
+| 选项轮转（正确选项被移走） | 16 次轮转只有 4 次「对」，且都是正确内容恰好落在它偏好的槽位；被选中的标签始终落在前 1–6 个槽位 |
+| `noul` 问题 | 退化为恒定回答 `true`（p ≈ 0.987–0.9998，5/5 次），与「恒答 true」基线同分 |
+| 置信度可用性 | 0.6B 错答均值 0.700 vs 全量 0.766；0.8B 0.373 vs 0.383 —— 无区分度，不能当弃权阈值 |
+
+阻塞点在**模型**（未训练 base 不具备「读选项表做分类」的能力），不在适配层：
+适配层把 Jev 响应的形状、归一化、延迟都做对了（`normalizeAnswers` **27/27** 通过、
+标签概率质量 0.9936–0.9999、冷/热一步 1.7–5.1 s）。**「零下载 / 零 Python」这条路本身不成立**，
+本地兜底要走有训练头的路线（Kev，见 `docs/local-kev-bringup.md`）。
+
+> 本文件只覆盖「未训练 GGUF + 首 token 读出」这条探针；模型选型背景见 `docs/local-models-research.md`。
+> 实验代码与全部原始输出保留在 `experiments/gguf-provider/`（**不属于 skill**，是负结果证据）。
+
+---
+
+## 1. 原型做了什么
+
+目录 `experiments/gguf-provider/`：纯 Node（无 npm 依赖、无 Python），把 llama.cpp 的
+单 token 分布包装成 Jev 的 `/v1/systemone`。
+
+| 文件 | 作用 |
+|---|---|
+| `lib/readout.mjs` | llama.cpp HTTP 客户端：`/tokenize`、`/apply-template`、`/completion`（`n_predict=1`、`n_probs=512`、samplers 全关）；把标签概率从分布里读出来 |
+| `lib/labels.mjs` | 选项标签：`A..Z, AA, AB, …`（bijective base-26），与 openjev 一致 |
+| `lib/render.mjs` | 渲染 `system + state + 选项表 + "Answer:"`；用**真实 tokenizer** 校验「标签在该表面形式下是单 token」 |
+| `lib/provider.mjs` | `systemOne()`：按题读标签概率 → 组装 Jev 形状的 `answers`（含 `confidence`） |
+| `serve.mjs` | `/v1/systemone` + `/v1/models` + `/health`；skill 只要 `TYPESAFE_BASE_URL` 指过来，**零改代码** |
+| `eval/`、`lab/` | 20 条自明真值评测、选项轮转、契约检查、延迟、tokenizer / 结束符 / noul 先验探针 |
+| `results/`、`fixtures/` | 全部原始输出与真实页面捕获（本文件每个数字都能在其中找到，见 §9） |
+
+**读出机制**（等价于 `ekzhang/openjev-sglang` 的 prefill-only 读法，但换成 llama.cpp）：
+
+1. 渲染：`system`（分类器人设）+ user（`state` JSON + 本题 + 带标签的选项表）+ 固定 cue（`Answer:`，
+   由适配层自己持有，不依赖模型模板结尾）；
+2. `/completion` 只预测 **1 个 token**，`n_probs=512`，**samplers 全部关闭**
+   （`temperature=1, top_k=0, top_p=1, min_p=0, repetition/presence/frequency penalty=0`）
+   → 返回的就是该位置**未经采样的 softmax 分布**（无生成、无解析、无文本后处理）；
+3. 读出：把各选项的标签 token 概率取出（`" A"` 与 `"A"` 两种表面形式相加），在选项集合上归一化
+   → `choice.probabilities`；`noul` 取 `true` 标签的 p；`score` 用 `Σ i·p(i)`，`confidence = 1 − H/log n`。

+## 3. 契约兼容：通过（唯一完全通过的部分）
+
+- `TYPESAFE_BASE_URL` 指到适配层后，**真实 skill CLI 退出码 0**、无 validation / parse 错误：
+  - 0.6B：`skills/jev-browser judge` 一步 **5,104 ms**（`usage.input_tokens=5294`），
+    返回 `model:"jev-latest"`、`answers{…}`、`usage`、`costUsd`（本地成本 $0）
+    → `results/skill-judge-0.6b.json`
+  - 0.8B：同一条命令 **2,701 ms**（`input_tokens=6877`）→ `results/skill-judge-0.8b.json`
+- **provider 响应不改动**即可被 skill 自己的 `validateQuestions` + `normalizeAnswers` 消费：
+  `lab/check-normalize.mjs` **27/27 PASS**（0.6B、0.8B 各跑一次：`results/check-normalize-0.6b.txt`、
+  `check-normalize-0.6b-recheck.txt`、`check-normalize-0.8b.txt`），包括
+  `probabilities` 键集齐全、和为 1、`ranked` 排序、`top === ranked[0][0]`、`score ∈ [0,3]`、
+  `legend` 与 criteria 逐字相等。
+- 标签读出质量：每题「标签概率质量」0.9936–0.9999（即标签几乎吸走全部概率）；
+  所有评测行的 `multi_token_labels` 均为空（字母表校验按预期工作）。
+
+**结论**：这条路的技术封装没有障碍 —— 问题完全在模型质量。
+
+---
+
+## 4. 准确率与行为证据
+
+评测集：**20 条真值由构造保证**的题目（`eval/items.mjs`）——15 条 browser（14 条从真实
+`--dry-run` 捕获的页面 state 上手工判定的决策题 + 1 条 `progress` 评分题）+ 5 条 passage 是非题（`noul`）。
+每个数字可在 `results/eval-0.6b.json` / `eval-0.8b.json` 与对应 `.log` 中逐条核对。
+
+### 4.1 总表（各 20 条）
+
+| 集合 | Qwen3-0.6B | Qwen3.5-0.8B | 「恒选第一个选项」基线 |
+|---|---|---|---|
+| 全部 20 | **11/20 = 0.55**（95% CI 0.34–0.74） | **10/20 = 0.50**（0.30–0.70） | **11/20 = 0.55** |
+| browser 15 | 9/15 = 0.60 | 7/15 = 0.47 | 9/15 = 0.60 |
+| noul 5 | 2/5 = 0.40 | 3/5 = 0.60 | 2/5 = 0.40 |
+
+逐问（n / 正确）：
+
+| 问题 | n | 0.6B | 0.8B |
+|---|---|---|---|
+| `click_target`（55 / 100 选项） | 2 | 1 | 0 |
+| `action` | 3 | 1 | 1 |
+| `blocker` | 2 | 2 | 2 |
+| `goal_done`（noul） | 1 | 0 | 0 |
+| `type_target` | 3 | 3 | 2 |
+| `submit_after_type`（noul） | 2 | 1 | 1 |
+| `type_value` | 1 | 0 | 0 |
+| `progress`（score） | 1 | 1 | 1 |
+| `answer`（noul，passage） | 5 | 2 | 3 |
+
+### 4.2 平凡基线：恒选第一个选项
+
+标签按**位置**分配（`e1` = 列表里第一个元素，`true` 恒为 noul 的第一个选项），所以
+「永远选第一个选项」是一个不需要读任何内容的策略。它的成绩：
+
+- 总 **11/20 = 0.55**（browser 9/15、noul 2/5）；
+- 0.6B 与它在 **16/20** 题上答案相同，仅 4 题不同（2 次对 / 2 次错）→ **总分与基线完全一致**；
+- 0.8B 与它在 13/20 题上相同，7 题不同（2 次对 / 5 次错）→ **低于基线**。
+
+即：0.6B 的 0.55「准确率」可完全由位置先验 + 噪声解释；0.8B 连这个先验都没稳定复现。
+
+### 4.3 选项轮转：答案跟着位置走，不跟着内容走
+
+把同一道题（`click_target`）的**选项内容整体轮转**、并同步改写 state 里的元素表与期望标签，
+正确内容会落到不同标签上（如 `e54`、`e53`、`e52`、`e48`）。结果：
+
+| 模型 | k=0 | k=1 | k=2 | k=3 | k=7 | 合计 |
+|---|---|---|---|---|---|---|
+| 0.6B（ddg，55 选项，want `e1`/`e54`/`e53`/`e52`/`e48`） | **e1 ✓** | e2 ✗ | e1 ✗ | e1 ✗ | e1 ✗ | 1/5 |
+| 0.6B（wiki，100 选项，want `e8`/`e5`/`e1`） | e1 ✗ | — | — | e6 ✗ | **e1 ✓** | 1/3 |
+| 0.8B（ddg） | e3 ✗ | e2 ✗ | e1 ✗ | e2 ✗ | e2 ✗ | 0/5 |
+| 0.8B（wiki） | e4 ✗ | — | — | **e5 ✓** | **e1 ✓** | 2/3 |
+
+- 两个模型合计 16 次轮转中只有 4 次「对」，且每次「对」都只是**正确内容恰好落在它偏好的前几个槽位**；
+- 被选中的标签在两个模型上都没有离开过**前 6 个槽位**（0.6B 的全部选中标签 ∈ {e1, e2, e6}；0.8B ∈ {e1…e5}）；
+- 当正确内容被轮转到 `e48`–`e54` 时，两个模型**一次都没有跟随过去**。
+
+→ 模型读的是「第几个选项」，不是「选项写了什么」。
+
+### 4.4 `noul` 与 prompt 表面先验
+
+- 20 条评测里 0.6B 的 5 条 passage 是非题**全部回答 `true`**，p ∈ [0.9869, 0.9998]
+  （含专门的反极性陷阱题 `bq-trap-failed`：原文说实验失败，仍答 true，p=0.9869）→ 2/5，与「恒答 true」同分。
+- `lab/probe-noul-bias.mjs`（7 条是非题 × 5 个 prompt 变体）—— 换系统提示词、换少样本示例、
+  把两个选项的**文字对调**（内容不变、标签互换）：
+
+| 变体 | 正确 | 选中标签 A 的次数 | 它实际执行的不变策略 | 该常量策略的命中率 |
+|---|---|---|---|---|
+| v1 基线 | 3/7 | 7/7 | 恒选 A | 3/7 |
+| v2 选项文字对调 | 3/7 | 2/7 | 不稳定（在两种常量间摆动） | — |
+| v3 严格系统提示 | 3/7 | 7/7 | 恒选 A | 3/7 |
+| v4 严格系统 + 少样本 | 4/7 | 0/7 | 恒选「NOT-STATE」 | 4/7 |
+| v5 仅少样本 | 4/7 | 0/7 | 恒选「NOT-STATE」 | 4/7 |
+
+→ 分数**等于**该变体所执行的常量策略的命中率；换 prompt 只是换了一种常量，
+没有任何一个变体表现出「按 state 判断」的行为。
+
+### 4.5 过自信：置信度不能当弃权阈值
+
+| | 0.6B | 0.8B |
+|---|---|---|
+| 12 个 choice/score 答案的 mean confidence | 0.766 | 0.383 |
+| 其中错答的 mean confidence | 0.700（4 个错答） | 0.373（6 个错答） |
+| 最自信的错答 | **0.944**（`github-login-type-value`：把用户名题答成 `password`） | 0.797（`ddg-click-target-aapl`） |
+| `noul` 最自信的错答 | 0.9969（`goal_done`，正确答案是 false） | 0.6235 |
+
+正确/错误答案的置信度分布几乎重合（0.6B: 0.766 vs 0.700；0.8B: 0.383 vs 0.373），
+**没有可用的弃权信号**：既不能靠阈值过滤错答，也不能用它触发 `wait`/人工接管。

+| 每步 input tokens | 5,099 | 6,877 |
+| 真实 skill `judge` 调用（§3） | 5,104 ms | 2,701 ms |
+
+- 每步耗时几乎全部来自**唯一那道 55/100 选项的题**（它的 prompt 里嵌了整个元素表，≈4.5–4.8k 新 token）；
+  其余问题的读出只要 0.1–0.3 s。
+- **反直觉**：更大的 0.8B 反而快 2–3×。`[INFERENCE]` 两个可能原因：Qwen3.5 的
+  `qwen35` 是混合线性注意力架构（长 prompt 的 prefill 成本远低于 `qwen3` 的全注意力）；
+  以及两次测量相隔约 1 小时、0.6B 服务进程已驻留且有历史负载。**这不是严格对拍**，只作量级参考。
+- 横向参考（同一台机器）：有训练头的 Kev-0.8B（MLX）同规模 step 是 2.8–3.4 s 热（见 `local-kev-bringup.md`）——
+  **延迟这一项 GGUF 路线没有优势**，因为瓶颈是 prompt prefill，不是生成。
+
+---
+
+## 6. 标签 token 化陷阱（实测，必须遵守）
+
+读出位置读的是**某一种表面形式**的标签 token，而 Qwen 分词器对
+`" AY"`（空格前缀，实际发射形式）与 `"AY"`（裸形式）**分词不同**，且例外集也不同
+（`results/tokenizer-0.6b.json`，逐字核对 128 个标签 A…?）：
+
+| 表面形式 | 单 token 数 / 128 | 不是单 token 的标签（必须跳过/特殊处理） |
+|---|---|---|
+| `"AY"`（裸） | 122 | `BQ` `BZ` `CJ` `CQ` `CZ` `DQ` |
+| `" AY"`（空格前缀，本项目实际用） | 123 | **`AY`** `BQ` `BZ` `CQ` `DQ` |
+| `"\nAY"`（换行前缀） | **0** | 全部（此形式不可用；模型也不会在这里发射 `\n`+标签） |
+
+要点：
+
+1. **必须在「模型实际发射的那个形式」上验证单 token**：`" AY"` 是单 token 而 `"AY"` 不是；
+   反过来 `CJ`/`CZ` 裸形式会被拆开。若按裸形式建表、却读空格形式，标签概率会静默错位。
+2. 同一个字母的两种形式是**不同 token**（`" A"` = id 362，`"A"` = id 32），所以读出时
+   两种形式的概率**相加**（`lib/readout.mjs`），只认「在服务端 tokenizer 里确实是单 token」的那些。
+3. 选项多时标签要走 `A..Z, AA..CV`（100 选项题需要 100 个标签），
+   生成器必须**逐个校验、跳过被拆分者、继续向后取**（`render.mjs: verifiedAlphabet`，
+   对齐 openjev 的 "verified single-token letter combinations"）——本次 20 条评测中
+   `multi_token_labels` 全为空，说明该校验按预期工作。
+4. 采样侧要**彻底关掉 samplers**（见 §1）并取 `n_probs=512`；即便如此，
+   排不进 top-512 的低概率标签会被读成 0（0.6B 有 1 行、0.8B 有 2 行出现这种
+   `missing_labels`，例如 100 选项题的 42 个尾部标签；这些行的标签质量和仍 ≥0.9936）。
+   这是**尾部失真**，不影响本次结论（答案都集中在前几个槽位），但换更平的概率分布时要注意。
+
+---
+
+## 7. 裁定：**不能作为随 skill 分发的零 Python 本地兜底**
+
+支持「不能」的证据（按决定性排序）：
+
+1. **准确率 = 平凡基线**：0.6B 11/20 与基线同分且 16/20 题答案相同；0.8B 10/20 低于基线。
+2. **轮转证伪「在读内容」**：正确选项被移出前几槽位后，16 次轮转里从未被跟上。
+3. **`noul` 退化为常量**：恒定 `true`（p≈0.99）；prompt 变体只是换成另一种常量，
+   得分恰好等于该常量的命中率。
+4. **置信度无区分度**：错答照样 0.70–0.94（0.6B）、最自信的错答 p=0.9969（`goal_done`）——
+   无法用阈值兜住。
+5. 唯一通过的是**工程封装**：契约 27/27、标签质量 ~1.0、冷/热一步 1.7–5.1 s、成本 $0。
+   也就是说：**换个有训练头的模型，这套适配层可以继续用；但未训练 sub-1B 这条路本身不成立。**
+
+什么条件下可以翻案（都不是本次实测支持的方向）：出现「专门为读选项做过训练」的 sub-1B 权重
+（= Kev 路线，但那是 Python/MLX，不是零 Python）；或换更大/指令微调模型 + 少样本 + 温度校准
+（超出「sub-1B、零下载」的前提，且 0.8B 的经验说明规模不是主要变量）。
+
+**给决定的一句话**：本地兜底请走 `docs/local-kev-bringup.md` 的 Kev 路线；
+本探针保留为**负结果证据**与将来的对照基线（换模型/换量化时可用同一套 `eval/` 重跑）。
+
+---
+
+## 8. 未覆盖 / 边界（诚实清单）
+
+- **样本小**：20 条自明真值 + 5 个真实页面捕获；0.6B 的 95% CI 为 0.34–0.74，不足以区分 0.5 与 0.7
+  的细微差别（但足以支撑「≈基线」与「不读内容」的定性结论，后者由轮转与 noul 常量行为直接证明）。
+- 只测了 **Q8_0** 量化；未测 Q4/Q5/IQ 档，未测其他架构（LFM2.5-350M、MiniCPM5-2B、Gemma-3-270m 等）。
+- 0.6B 的量化文件是 **Instruct** 版本，不是 JEV-CPU / SemIf 用的 **Base**；Base 未测（未新增下载）。
+- 只用了**一种 ending**（`Answer:` cue）与「空格前缀」标签形式；`probe-ending` 显示另外两种 cue 也能读出标签，
+  但未做准确率对比。
+- 未做**温度校准 / 少样本规模化 / 指令微调格式**的实验（只在 noul 上试了 5 个变体）；
+  未测多问题并行批处理（当前每题一次 HTTP 请求）；未测更长 state 的上下文退化。
+- 0.6B 与 0.8B 的**延迟对比不是严格对拍**（测量时间、进程驻留状态不同，见 §5）。
+- 未评估把该读出用在**非分类任务**（如自由文本抽取）上——本探针只覆盖 `noul`/`choice`/`score`。

+`serve` extra 实测关键依赖：`torch==2.8.0`、`transformers==5.17.0`、`peft==0.21`、
+`mlx-lm`（darwin/arm64）、`fastapi`、`uvicorn==0.53.0`、`typesafe-sdk==0.6.0`。
+
+> **坑 1**：`uv sync` 用 `.python-version`（3.13），不是系统 python3.12。
+> `requires-python = ">=3.12,<3.14"` —— 别用 3.14（torch 无 wheel）。
+
+---
+
+## 2. 启动
+
+### 2.1 brief 里的命令会直接报错（`--host` 不存在）
+
+```bash
+uv run --extra serve python -m kev.serve --run jaredpalmer/kev-0.8b --port 8008 --host 127.0.0.1
+```
+
+```
+usage: serve.py [-h] [--run RUN] [--fallback FALLBACK] [--port PORT]
+serve.py: error: unrecognized arguments: --host 127.0.0.1
+EXIT=2
+```
+
+原因（`kev/serve.py` 的 `main()`）只定义了 `--run` / `--fallback` / `--port`，host 硬编码：
+
+```python
+import uvicorn
+uvicorn.run(app, host="127.0.0.1", port=a.port)
+```
+
+**`--host` 必须去掉**；监听地址永远是 `127.0.0.1`。
+
+### 2.2 可用命令
+
+```bash
+cd ~/.local/share/jev-browser/kev
+uv run --extra serve python -m kev.serve --run jaredpalmer/kev-0.8b --port 8008
+```
+
+跳过 `uv run` 开销（**坑 3**：`uv run` 每次约 49 s）：
+
+```bash
+~/.local/share/jev-browser/kev/.venv/bin/python -m kev.serve --run jaredpalmer/kev-0.8b --port 8008
+```
+
+脱离终端 + 落盘日志：
+
+```bash
+cd ~/.local/share/jev-browser/kev
+nohup ~/.local/share/jev-browser/kev/.venv/bin/python -m kev.serve \
+  --run jaredpalmer/kev-0.8b --port 8008 \
+  >> ~/.local/share/jev-browser/work/kev-serve.log 2>&1 &
+echo $! > ~/.local/share/jev-browser/work/kev.pid
+```
+
+本次实测实际由 harness 进程管理器拉起（`hub start name=kev`），所以本会话有两个 PID：
+`uv` 包装进程 **56298**、真正服务的 python 子进程 **56489**（日志经 supervisor 捕获，内容同上）。
+
+### 2.3 启动日志

+```
+
+### 2.4 首次下载体积（**坑 2**：不能用 repo 目录量）
+
+HF 新版 Xet 布局把大文件放 **共享** 的 `hub/blobs/xx/…`，每个 repo 目录只剩符号链接和元数据，
+所以 `du -sh models--Qwen--Qwen3.5-0.8B-Base` 只有 9.7 MB —— 那是假象。真实体积：
+
+```
+1.6G  ~/.cache/huggingface/hub/blobs/0a/0a75…   # 1,746,942,600 B  Qwen3.5-0.8B 基座权重

+2.0M  ~/.cache/huggingface/hub/blobs/b5/b54e…   #     2,103,103 B  head.pt
+```
+
+合计 ≈ **1.72 GiB**（另有 `~/.cache/huggingface/xet` 36 MB 分片暂存）。
+
+> `--fallback` 默认 `runs/smoke`：`--run` 既非 hub id、本地又无 `<run>/head.pt` 时，
+> 会**静默回落**并打印 `… not found, falling back to …`（**坑 7**）。
+
+---
+
+## 3. 契约验证
+
+### 3.1 `GET /v1/models`
+
+```bash
+curl -s http://127.0.0.1:8008/v1/models | jq .
+```
+
+```json
+{
+  "models": [
+    {
+      "name": "kev-latest",
+      "description": "Kev pointer head on Qwen/Qwen3.5-0.8B-Base, serving jaredpalmer/kev-0.8b at temperature 2.41",
+      "release_date": "2026-09-21",
+      "run": "jaredpalmer/kev-0.8b",
+      "base": "Qwen/Qwen3.5-0.8B-Base",
+      "lora": 16,
+      "device": "mps",
+      "backend": "mlx",

+      "temperature": 2.406050072164233,
+      "prefix_cache": { "size": 4, "min_state_tokens": 0, "hits": 0, "misses": 0, "cached_states": 0 }
+    },
+    { "name": "jev-latest", "…": "同上，同一 checkpoint 的第二个别名" }
+  ]
+}
+```
+
+- 只注册 `kev-latest` / `jev-latest`（`serve.py: MODEL_NAMES`）。
+- **`jev-latest` 正是 skill CLI 的默认 model** → 零配置命中。
+
+### 3.2 `POST /v1/systemone` 接受哪些 model id
+
+`SystemOneRequest.model: str = "kev-latest"` —— **无白名单校验**，任何字符串都收，只原样回显：
+
+| 请求 `model` | HTTP | 回显 |
+|---|---|---|
+| `kev-latest` | 200 | `"model":"kev-latest"` |
+| `jev-latest` | 200 | `"model":"jev-latest"` |
+| `kev-0.8b` | 200 | `"model":"kev-0.8b"` |
+
+> `kev-0.8b` **不会**切换 checkpoint（服务只加载 `--run` 指定的那个），只是回显（**坑 6**）。
+
+### 3.3 noul + choice + score 批量返回（逐字）
+
+```json
+{"model":"kev-latest","answers":{
+  "department":{"type":"choice","choice":"returns","confidence":0.0809,
+                "probabilities":{"returns":0.3873,"shipping":0.3767,"billing":0.236}},
+  "escalate":{"type":"noul","noul":0.5878},
+  "frustration":{"type":"score","score":1.2876,
+                 "legend":{"0":"Calm","1":"Frustrated","2":"Very angry"},
+                 "probabilities":{"0":0.0418,"1":0.6288,"2":0.3294},"confidence":0.8144}},
+ "usage":{"input_tokens":101,"output_tokens":181},"latency_ms":10280.8}
+```
+
+**结论：`lib/typesafe.mjs` 的 `normalizeAnswers()` 可原样消费**，字段逐项对齐：
+
+| `normalizeAnswers` 需要 | Kev 返回 |
+|---|---|
+| `answer.type === question.type` | ✅ 每个答案带 `type` |
+| noul: `answer.noul` ∈ [0,1] | ✅ |
+| choice: `probabilities` / `choice` / `confidence` | ✅ |
+| score: `probabilities` / `score` / `legend` / `confidence` | ✅ |
+| `usage.input_tokens` / `output_tokens` | ✅ 顶层 `usage` |
+
+其它实测：
+- 响应头带 `x-typesafe-request-id`。
+- `usage.output_tokens` 统计**序列化答案**的 token 数（100 选项的 choice 会到 1,520），不是生成量；
+  skill 只按 input token 计费，口径一致。
+- `KEV_API_KEY` 未设置时服务**开放**；skill 总带 `Authorization: Bearer <key>`，故 `local` 占位够用。
+- 非法 `type` 返回 422（FastAPI 校验），空 `questions` 同样 422 —— skill 侧 `validateQuestions()` 已提前拦截。
+
+---
+
+## 4. 延迟：冷 vs 热（真实浏览器步负载）
+
+负载取自 skill 真实首步（不花 API 钱）：
+
+```bash
+node skills/jev-browser/bin/jev-browser.mjs run --dry-run --json \
+  --goal "the Wikipedia article about Ada Lovelace is shown" --url https://en.wikipedia.org
+```
+
+- **payload 29,919 B**（`state` + `questions`）→ 服务端 **8,411 input / 1,520 output tokens**
+- 问题集：`goal_done`(noul) + `blocker`(6 选项) + `action`(4 选项) + `click_target`(**100 选项**)
+- skill 自估 7,765 input tokens ≈ $0.00033；服务端实际 8,411 —— 同量级
+
+同一 payload 连续回放：
+
+| 次序 | HTTP | 端到端 | 服务端 `latency_ms` | 说明 |
+|---|---|---|---|---|
+| 1 | 200 | **8.810 s** | 8,550.5 | 冷（MLX kernel 编译） |
+| 2 | 200 | **3.367 s** | 3,238.5 | 热（state 前缀缓存命中） |
+| 3 | 200 | **2.852 s** | 2,775.3 | 热 |
+| 4（`model=kev-0.8b`） | 200 | **2.946 s** | 2,869.9 | 同 state，命中同一前缀缓存 |
+
+四次返回**逐字节一致**（确定性，无采样）。
+
+其它：
+- 启动后**第一次**调用即便 payload 很小也要 ~10.9 s（一次性 warm-up），之后 0.16 s。
+- 前缀缓存 `size=4`：被小 payload 挤掉后重算同一大 state 回到 **15.88 s**。
+  真实 browse 每步 state 都在变 → **每步基本按冷/半冷算**。
+
+---
+
+## 5. 加速：本机实际生效的路径
+
+默认值（除 `--run` 外零配置）就是本机最优：`device=mps backend=mlx dtype=bfloat16`。
+Kev 在 Apple Silicon 上默认走 MLX（`serve.py` 里 `opts.backend="auto"`，hybrid Qwen3.5 → MLX），
+与官方 README 的 "Serving Performance" 一致。
+
+### A) `KEV_BACKEND=torch`
+
+```
+KEV_BACKEND=torch .venv/bin/python -m kev.serve --run jaredpalmer/kev-0.8b --port 8010
+```
+
+- 状态 **ready**，`/v1/models` 200，推理 200；小批量首次推理 **37.34 s**
+- 逐字警告（两条都会出现）：
+
+```
+[transformers] `causal_conv1d_fn` is falling back to its reference PyTorch implementation
+because `causal_conv1d` is not installed. This is correct but much slower; install
+`causal_conv1d` for the optimized version.
+
+[transformers] `chunk_gated_delta_rule` is falling back to its reference PyTorch implementation
+because `flash-linear-attention` is not installed. This is correct but much slower; install
+`flash-linear-attention` for the optimized version.
+```
+
+### B) `KEV_DTYPE=fp32`（文档里的"精确评估路径"）
+
+- **ready**，推理 200，小批量 **8.35 s**（torch 路径，kernel 已预热）；同样两条 fallback 警告
+- 语义：`KEV_DTYPE=fp32` 会顺带把 backend 切到 `torch`
+  （`checkpoint.py`：`exact = opts.dtype is torch.float32` → 返回 `"torch"`，**坑 10**）
+
+**两条非 MLX 路径都不报错**——只是慢。MLX 是唯一值得用的加速路径。
+
+> 退出时另有无害警告：`resource_tracker: There appear to be 1 leaked semaphore objects …`。
+
+---
+
+## 6. 端到端（通过 skill）
+
+```bash
+export TYPESAFE_API_KEY=local
+export TYPESAFE_BASE_URL=http://127.0.0.1:8008
+```
+
+### 6.1 `judge` —— 退出码 0，**无 validation/parse 错误**

+```
+
+`pick_exit=0`。短 state + 少选项的判断，0.8B 表现**正常**（3 选 1 精确命中 pricing 0.94）。
+
+### 6.3 `doctor` —— 退出码 0，本地后端被正确识别

+
+三次都**没有 validation / parse 错误、没有异常退出**（schema 全对）——
+**但三次全是假成功。**
+
+### 6.5 诚实结论：判断质量
+
+三次都停在 `en.wikipedia.org/wiki/Main_Page`（首页，**不是** Ada Lovelace 词条），
+模型却给出 `goal_done ≈ 0.88–0.89`，超过 skill 的 `thresholds.goalDone = 0.85`，
+于是控制器在第 1 步、**零动作**的情况下宣布 `success`。
+
+对照实验（**同一问题、同一 instructions，只换 state**）：
+
+| state | 真实情况 | Kev-0.8B `goal_done` |
+|---|---|---|
+| 203 tokens，Wikipedia 首页 | **未完成** | **0.792** |
+| 225 tokens，"Ada Lovelace - Wikipedia" | 已完成 | 0.903 |
+| 8,411 tokens，真实浏览器步 | **未完成** | **0.895** |
+
+模型对"完成 / 未完成"**几乎不做区分**（0.79 vs 0.90），所以
+**Kev-0.8B 在 skill 的 `goal_done` 问题上不可用**：不是 prompt 太长淹没，是模型/标定问题。
+
+- 官方 model card 写了同一边界：非训练域准确率 **0.652**，"Probabilities are usable in-domain;
+  treat them as advisory elsewhere"。
+- 0.8B 还带一个拟合出的 `temperature=2.41`，把概率整体压向 0.8–0.9 区间（`KEV_TEMPERATURE=1.0` 可关）。
+- 退化是**针对性的**：短 state + 少选项（§6.2）正常；长结构化 state + 大量候选项时最差——
+  `click_target` 的 top-2 是 `e1` 0.231 / `e28` 0.216，**几乎掷硬币**。
+
+对 `run` 的影响是致命的：`goal_done` 恒高 ⇒ 永远第 1 步"成功"，
+`blocker` / `action` / `click_target` 的判断**根本没机会被执行**。
+
+---
+
+## 7. `jaredpalmer/kev-0.6b`（Qwen3 基座）对照
+
+触发条件：0.8B 机械上可用、但判断质量不可用（§6.5），故按 brief 补测更小的 0.6B。
+
+```bash
+--run jaredpalmer/kev-0.6b --port 8012

+ "device":"mps","backend":"torch","dtype":"bfloat16","temperature":1.0}
+```
+
+就绪耗时 **40.2 s**（Qwen3 是 attention-only，走 torch/MPS，**不用 MLX**）。探针对照：
+
+| 探针 | kev-0.8b（T=2.41, mlx） | **kev-0.6b（T=1.00, torch）** |
+|---|---|---|
+| tiny state，**未完成** | 0.792 | **0.810** |
+| tiny state，已完成 | 0.903 | **0.9874** |
+| 小批量 3 问 `department` | `returns` 0.387 | **`billing` 0.512** |
+| 真实 8.4k workload `goal_done` | **0.895**（> 阈值 → 假成功） | **0.5877**（< 阈值） |
+| 真实 workload 延迟 | 冷 8.55 s / 热 2.8 s | **16.72 s** |

+  "elapsedMs": 59537 }
+```
+
+**EXIT=0，wall 63 s。**
+
+结论：
+- 0.6B 在 step 1 给出 0.53（低于阈值）→ **没有立刻假成功，确实动手了**；
+  但它点的是首页轮播的 `Full article...`，跳到**当天的特色条目 Mary Mallon**（不是 Ada Lovelace），
+  然后在 step 2 又把错误页面判成 0.89 → 仍然假成功，只是把失败推迟了一步。
+- 0.6B 仍然**不区分**完成/未完成（0.81 vs 0.99）；温度 1.0 没被压扁，所以数值更极端。
+- 0.6B 在真实负载上**更慢**（16.7 s vs 2.8 s 热）：Qwen3 基座走 torch + 两条 reference fallback，吃不到 MLX。
+- 官方数字也支持：0.6B 非训练域 0.620 < 0.8B 0.652。
+
+**所以 0.6B 不是解法**——它把"一步假成功"换成"两步假成功 + 慢 6 倍"。
+真正要修的是标定/阈值/模型规模（README 家族表：4B 非训练域 0.797，9B 0.822）。
+
+---
+
+## 8. 坑清单（gotchas）
+
+1. **`--host` 不存在** → `serve.py: error: unrecognized arguments: --host 127.0.0.1`（EXIT=2）；host 永远 `127.0.0.1`。
+2. **HF Xet 布局**：大权重在共享 `hub/blobs/xx/…`，repo 目录 `du` 只有几 MB；真实总量 ≈ 1.72 GiB。
+3. **`uv run` 每次约 49 s**（即便 venv 与模型已就绪）；反复重启请直接用 `.venv/bin/python`。
+4. **首次推理 ~8.5–11 s**（MLX kernel warm-up），与 payload 大小无关；warm 后 0.16 s（小 payload）。
+5. **前缀缓存只有 4 个 state**（`KEV_PREFIX_CACHE=4`, `min_state_tokens=0`）；被挤掉后重算 15.9 s。
+6. **`model` 不校验、只回显**：`kev-0.8b` 也返回 200，但不切模型；只有 `--run` 决定 checkpoint。
+7. **`--fallback runs/smoke`**：`--run` 指错时**静默回落**，只打印一行提示。
+8. **未认证下载警告**：`Warning: You are sending unauthenticated requests to the HF Hub.`（不设 `HF_TOKEN` 也能跑）。
+9. **非 MLX 路径的两条 reference fallback 警告**（`causal_conv1d`、`flash-linear-attention` 未装）是"慢"，不是错误。
+10. **`KEV_DTYPE=fp32` 会顺带把 backend 切到 torch**（不是"MLX 上的 fp32"）。
+11. 退出时有 `resource_tracker: … 1 leaked semaphore objects …` 警告，无害。
+12. 服务默认**无鉴权**（`KEV_API_KEY` 未设置），只听 `127.0.0.1`。
+13. 0.8B 的 `temperature=2.41` 是 checkpoint 内拟合值（存在 `head.pt`）；`KEV_TEMPERATURE=1.0` 才给原始 logits。
+14. 选 0.8B 时 **MLX 是唯一值得用的后端**；`KEV_BACKEND=torch` / `KEV_DTYPE=fp32` 都能跑但慢一个量级。
+

+
+## 9. 停止命令
+
+本会话实际使用（supervisor 管理，名字 `kev` / `kev06b`）：
+
+```bash
+hub stop kev
+hub stop kev06b          # 若曾启动 0.6B
+```
+
+若按 §2.2 的 `nohup` 方式起：
+
+```bash
+kill "$(cat ~/.local/share/jev-browser/work/kev.pid)"
+```
+
+兜底（按命令行匹配）：
+
+```bash
+pkill -f "kev.serve --run jaredpalmer/kev-0.8b --port 8008"
+pkill -f "kev.serve --run jaredpalmer/kev-0.6b --port 8012"

+
+## 10. 质量矩阵：checkpoint × temperature（phase 1b，有界 ≤40 请求）
+
+问题：是否存在 **任何** 本地配置，能让模型在本 skill 的问题集上做出可用判断？
+下面只放决策所需的数字（原始概率）。
+
+### 10.1 A) 温度：`kev-0.8b` × {T=2.41 服务默认, T=1.0 原始 logits}
+
+T=1.0 服务器（`/v1/models` 已确认 `"temperature":1.0`）：
+
+```bash
+KEV_TEMPERATURE=1.0 .venv/bin/python -m kev.serve --run jaredpalmer/kev-0.8b --port 8014
+```
+
+| 探针 | T=2.41（8008） | T=1.0（8014） |
+|---|---|---|
+| tiny state，**未完成** → `goal_done` | **0.792** | **0.9615** |
+| tiny state，已完成 → `goal_done` | 0.903 | 0.9953 |
+| real 8,411-token，**未完成** → `goal_done` | **0.895** | **0.9943** |
+| real `click_target` top-2 | `e1` 0.231 / `e28` 0.216（差 0.015） | `e1` 0.5176 / `e28` 0.4428（差 **0.075**） |
+| real `action` | click 0.467 / scroll_down 0.285 / stop 0.227 / wait 0.022 | click 0.676 / scroll_down 0.205 / stop 0.119 / wait 0.0004 |
+| real `blocker` | none 0.350 / error_page 0.257 / missing_info 0.192 | none 0.564 / error_page 0.268 / missing_info 0.133 |
+| batch `department` | returns 0.387 / shipping 0.377 / billing 0.236 | returns 0.447 / shipping 0.418 / billing 0.136 |
+| batch `escalate` (noul) | 0.588 | 0.701 |
+| batch `frustration` (score) | Frustrated 0.629 / Very angry 0.329 | Frustrated 0.825 / Very angry 0.174 |
+| judge `team` | returns 0.4045 / shipping 0.3771 / billing 0.2184 | returns 0.4828 / shipping 0.4077 / billing 0.1095 |
+| judge `urgent` (noul) | 0.578 | 0.681 |
+| pick `pricing` | 0.9375 | **0.9987** |
+| real workload 延迟 | 冷 8.55 s / 热 2.78–3.24 s | 冷 7.12 s / 热 2.70 s |
+
+**T=1.0 不能恢复可用分离度**——它把分布整体"锐化"（click 间距 0.015→0.075、pick 0.9375→0.9987），
+但 `goal_done` 的 done/not-done 间距反而从 **0.111 缩到 0.034**：
+
+| 温度 | not-done 取值 | done 取值 | 可放进阈值区间 | 区间宽度 |
+|---|---|---|---|---|
+| T=2.41 | {0.792, 0.895} | {0.903} | (0.895, 0.903) | **0.008**（纯噪声） |
+| T=1.0 | {0.9615, **0.9943**} | {0.9953} | (0.9943, 0.9953) | **0.001** |
+
+**没有任何阈值能把"未完成"和"已完成"分开**，两个温度都不行。
+
+另一个负面结论：tiny 控制组（203 tokens）本身就是 0.792 / 0.9615，
+所以 **observation trimming 救不了 `goal_done`** —— 不是长 state 淹没了模型，缩短 observation 只会省延迟。
+
+### 10.2 B) `kev-4b`：**根本拉不下来**（决定性结果，逐字）
+
+> **2026-09-24 更新：本节结论已被复测推翻。** 4B 权重已完整下载并通过 sha256 校验，
+> `kev.serve --run jaredpalmer/kev-4b` 已在本机跑通（服务卡上报 temperature 2.1435）—— 见 §11。
+> 下面的逐字记录保留为当时的现场证据，不要再据此认为 4B「取不到」。
+
+```bash
+.venv/bin/python -m kev.serve --run jaredpalmer/kev-4b --port 8014
+```
+
+supervisor 逐字：
+
+```
+Started kev4b: starting pid=33609 uptime=25m restarts=0
+NOT ready — readiness timed out after 1500s: port 8014 on 127.0.0.1 never accepted connections.
+The process is still running (state: starting); follow its logs or stop it.
+```
+
+28 分钟后实际落盘：
+
+```
+$ du -sk ~/.cache/huggingface/hub/models--jaredpalmer--kev-4b
+4508                      # 4.4 MB（adapter repo 自身未完成）

+ 48K  …/blobs/9797de69….778e91df.incomplete      # 在传文件定格 48 KB
+```
+
+同一时刻对 `hub/blobs` 与 `xet` 取两次样（间隔 25 s）：**零增长**。
+日志显示的是**重试循环**（`Fetching 13 files` 反复重建），瞬时速率只有 **5–40 kB/s**：
+
+```
+Fetching 13 files:   0%|          | 0/13 [00:00<?, ?it/s]

+Downloading bytes: ████ | 70.0MB, 15.9kB/s
+[kev4b: starting; cursor=537787]
+```
+
+对照：0.8B 首次下载 1.72 GiB 只用 ~96 s（≈18 MB/s）。4B 的基座约 **8.1 GB**，
+按 25 kB/s 需要 **~90 小时** —— `--run jaredpalmer/kev-4b` 在本机/本网络下**不可行**。
+
+因此 **4B 的任何探针都测不了**：没有 `goal_done` / `click_target` / browse run 数据。
+不是"效果不好"，是"取不到"。按指示，**不再去找别的模型**（zero-Python fallback 是另一个 worker 的活）。
+
+### 10.3 C) 判定表：{kev-0.8b, kev-4b} × {T=1.0, T=2.41}
+
+| 配置 | done / not-done（tiny） | 分离度 | real workload 的 not-done | 可用？ |
+|---|---|---|---|---|
+| `kev-0.8b` T=2.41 | 0.903 / 0.792 | 0.111 | **0.895** → 第 1 步假成功 | **否** |
+| `kev-0.8b` T=1.0 | 0.9953 / 0.9615 | **0.034** | **0.9943** → 更严重假成功 | **否（更差）** |
+| `kev-4b` T=2.41（实测为其自带 T=2.1435） | 未测（未做 tiny 探针） | 未测 | 真实 fixture 页 **0.0607**（0.8B 是 0.6952 假成功） | **是（19/20 = 0.95）**：阈值带 0.341–0.683、`click_target` 2/2；见 `experiments/kev-4b/README.md` |
+| `kev-4b` T=1.0 | 未测 | — | 未测 | 未测（4B 在自身温度下已可用；上行为实测值） |
+| （参考）`kev-0.6b` T=1.0 (torch) | 0.9874 / 0.810 | 0.177 | 0.5877 → 多走一步后仍假成功（Run D） | **否** |
+
+**判定依据 = 可行阈值区间的宽度**：
+T=2.41 是 **0.008**、T=1.0 是 **0.001**、4B 当时无法测量（现已可下载，见 §11）。三者都低于噪声水平
+⇒ **0.8B / 0.6B 任何配置都不能让模型在本 skill 的问题集上做出可用判断。**
+
+> **2026-09-24 更新：4B 已测，结论只对 0.8B/0.6B 成立。** `jaredpalmer/kev-4b` 在同一 20 条自明真值上
+> **19/20 = 0.95**（发布行上限下 18/20），真实 fixture 页 `goal_done` **0.0607**（0.8B 是 0.6952 的假成功），
+> 同一 15 个 run 回放的可用带是 **0.341–0.683**（0.482 处 7 正确 / 0 假成功 / 0 假 stuck）—— 即 **4B 可以驱动 run**。
+> 代价与命令见 `experiments/kev-4b/README.md`；技能侧已按后端自动选阈值（`thresholds.profile`，
+> 见 `skills/jev-browser/references/config.md`）。**下面的 least-bad 建议仅适用于继续使用 0.8B 的情况。**
+
+若要保留一条本地默认（工程上的"least bad"）：
+
+- **checkpoint**：`jaredpalmer/kev-0.8b` —— 当时唯一能稳定下载（1.72 GiB / 96 s）并启动的；4B 现已同样可用（§11），见上面的更新
+- **temperature**：保持服务默认 **T=2.41**（不要设 `KEV_TEMPERATURE=1.0`，分离度反而更差）
+- **threshold**：**不要动阈值**。可行区间 0.008 属噪声，调阈值不可能修好；必须改**判定逻辑**
+- **observation trimming**：**不解决 `goal_done`**（203-token 控制组已经是 0.792/0.9615），只用来省延迟
+- **因此**：本地 Kev 只适合**短 state 的辅助判断**（`pick` 0.94–0.9987、短 choice 稳定），
+  `goal_done` 必须交给**确定性检查**（URL/title/文本谓词），或把 Kev 降级为"继续/停止"的次要信号
+
+### 10.4 D) 收尾与 PID
+
+| 服务器 | 端口 | PID | 状态 |
+|---|---|---|---|

+
+## 11. Kev-4B 权重：发布状态复测 + 落盘（2026-09-24）
+
+§10.2 曾把 `jaredpalmer/kev-4b` 记为「无法获取」（28 min 只落盘 4.4 MB，5–40 kB/s，推 ~90 h）。
+**这个结论不成立**：仓库是完整的，本次把适配器与基座全部下载下来并逐文件校验通过，服务也跑通了。
+原读数的成因有两条，但只有第一条是本次实测证实的：① 5 MiB 窗口正好落在 TCP 爬坡段（前 ~20 s，见 §11.5 表）；
+② 当时走的是 hf_hub 的下载路径（含 Xet 客户端）—— 本次在同一链接上没复现出卡死（§11.5 的 A/B），
+所以当年那次 28 min 的读数与 curl 不是同一测量口径，不能互相外推。本次用 `curl` + 64 MiB 窗口复测：
+
+- 同一链接上所有来源 64 MiB 窗口都在 **1.56–2.27 MB/s**（HF 系）与 **5.54–5.70 MB/s**（ModelScope）；
+- 适配器 129,924,032 B **实际下载 2.486 MB/s、58 s 完成**（此前 28 min 未完成）；
+- 结论：仓库完整、可下载；此前「拿不到」的判断不成立。

+| HF 双流并行（shard1+shard2） | 每流 64 MiB | 1.767 / 1.765 | 聚合 3.728 |
+| ModelScope 双流并行 | 每流 64 MiB | 5.436 / 5.466 | 聚合 ≈10.9 |
+
+读数要点：所有窗口都 ≥64 MiB、都是 206 全窗口；HF 侧单流受每连接限速，加一条连接约翻倍；
+ModelScope 单流就是 HF 的 3.4 倍。
+
+> 短窗口 vs 长程：ModelScope 双流的 10.9 MB/s 来自 13 s 的探测窗口；真正的 9.34 GB 拉了 22.5 min，
+> 长程聚合回落到 **~5.5–7.4 MB/s**（每流滚动均值 ~2.9 MB/s）。报数时以长程为准，短窗口只用来排序来源。
+
+### 11.3 落盘位置与布局（`--run` 解析路径不变）
+
+写进 HF 缓存 `~/.cache/huggingface/hub/models--jaredpalmer--kev-4b/`，**命名规则与 `hf_hub` 自己写的完全一致**：
+LFS 文件在 `blobs/<lfs sha256>`、小文件在 `blobs/<git blob oid>`，另加 `trees/<commit>.json`、`refs/main`、
+`snapshots/<commit>/<file>` 符号链接。（差别只在实体存放方式：hf_hub 的 Xet 模式把大文件写成
+`blobs/<sha256> -> ../../blobs/<xx>/<xet-hash>` 的符号链接指向共享池，curl 落盘则是直接写实体文件；
+两种形态 hf_hub 都能解析，下面这条离线解析就是证据。）因此 `kev.serve --run jaredpalmer/kev-4b` 的解析路径无需任何改动：
+
+```
+$ HF_HUB_OFFLINE=1 .venv/bin/python -c "from kev.checkpoint import resolve_run; print(resolve_run('jaredpalmer/kev-4b'))"
+/Users/light/.cache/huggingface/hub/models--jaredpalmer--kev-4b/snapshots/485ace8703592fcf405488b262449990824cfed1
+```
+
+`head.pt` 逐字（来自落盘后的 checkpoint）：`base=Qwen/Qwen3.5-4B-Base`、
+`base_revision=1001bb4d826a52d1f399e183466143f4da7b741b`（= 基座 main，未漂移）、`lora=16`、`head_dim=256`、
+`temperature=2.1435469250725863`（in-repo 拟合值，1264 行开发集）。
+
+> **温度有两个数，别混**：`head.pt["temperature"] = 2.1435` 是 delta 之后重拟的、**服务实际使用**的值
+> （`checkpoint.py: m.head.temperature = meta.temperature`，`/v1/models` 也报这个）；
+> 同一个 checkpoint 里的 `result.json["temperature"] = 2.3784` 是 delta **之前**那次 trial 的旧拟合值，
+> 加载路径不读它。`KEV_TEMPERATURE=1.0` 才是关掉温度、走原始 logits。
+
+### 11.4 基座（`Qwen/Qwen3.5-4B-Base`，13 文件 9,342,824,751 B）
+
+（§10.2 里写的「基座 8.1 GB」是 GiB 口径的近似；实测 13 个文件合计 **9,342,824,751 B = 8.70 GiB**。）
+
+来源选 **ModelScope**（唯一独立镜像；分片 sha256 与 HF LFS oid 逐字一致，字节仍按 HF tree 元数据命名 + 校验）。
+下载方式：两个分片两条 `curl -C -` 流并行，30 s 采样一次滚动均值，低于 0.3 MB/s 即中止。
+
+| 项 | 结果 |
+|---|---|
+| 文件 / 体积 | 13 文件 · **9,342,824,751 B（8.70 GiB）** |
+| 分片 sha256 | shard1 `df547074…d712` ✅、shard2 `590fbaac…15ef` ✅（与 HF LFS oid 一致） |
+| 分词器 / 小文件 | `tokenizer.json` `fe000e3e…9272` ✅；其余 10 个小文件按 git blob sha1 ✅ |
+| 落盘位置 | `~/.cache/huggingface/hub/models--Qwen--Qwen3.5-4B-Base/`（`blobs/` + `snapshots/1001bb4d…/` + `trees/` + `refs/main`） |
+| 用时 | 分片并行 ~22.5 min（job 全程含校验 1,379.9 s）；小文件 23.0 MB 另走 HF ~50 s |
+| 实测速率 | 两条流各 3.88 / 3.52 MB/s（含校验耗时）；长程滚动均值 ~2.9 MB/s / 流，聚合 ~5.5–7.4 MB/s |
+
+> 一次自家 bug 的中断：首轮 240 s 被监控线程误判中止（当时监控只统计"已完成"字节，没把 `.incomplete` 的增长算进去），
+> 已修好并复跑；已落盘的 709.6 MB + 710.5 MB 由 `curl -C -` 直接续传，没有重下。
+> 小文件必须来自 HF：ModelScope 的 `.gitattributes` 是 2,335 B，HF 是 1,570 B —— 用 ModelScope 下会与 HF 元数据校验不符。
+
+### 11.5 复查原来的「判死」依据
+
+| 原判据 | 本次复测 |
+|---|---|
+| 28 min 只落盘 4.4 MB | 那 4.4 MB 是**小文件 + 元数据**（本次查看缓存确认：当时 129.9 MB 的大文件只落了 45 KB 的 `.incomplete`）。同一条链接、同一个 URL，这次用 curl 跑完 129.9 MB 只用了 58 s。 |
+| 速率 5–40 kB/s | 那次读数是 hf_hub 客户端在 28 min 窗口里的表现；本次 curl 在 64 MiB 窗口起手就是 1.5 MB/s。两者不是同一测量口径，不能互相外推。 |
+| 「基座 8.1 GB ⇒ ~90 h」 | 90 h 是把上述坏速率线性外推的结果。实测：ModelScope 双流短窗口 ~10.9 MB/s（投影 ~14 min），长程聚合 5.5–7.4 MB/s ⇒ **实测 9.34 GB 用时 ~22.5 min**；HF 单流 1.59–2.27 MB/s ⇒ 1.1–1.6 h。 |
+| 引擎差异 | 同一链接上 curl 明显快于 hf_hub 的下载路径（本次 129.9 MB 适配器：curl 58 s）；`hf_hub` 1.32 还带 Xet 客户端（`HF_HUB_DISABLE_XET=1` 可退回普通 HTTP）。本次直接绕开该路径，用 curl 传输、脚本负责续传与校验。 |
+
+> 引擎 A/B 的诚实结论：在同一个 8,394,495 B 的 xet 文件上跑三臂 —— `hf_hub` 默认（Xet）14.7 s、
+> `HF_HUB_DISABLE_XET=1` 9.0 s、`curl` 17.5 s —— **三者都落在 ~20 s 的 TCP 爬坡段内，这个实验区分不了引擎**；
+> 它能证明的只有：hf_hub 的客户端现在能把这 8.4 MB 下完（不再有卡死重试循环）。
+> 真正有分辨力的是大文件：curl 在 64 MiB 窗口上的 1.5–2.3 MB/s（HF）与 5.4–5.7 MB/s（ModelScope）是可复现读数。
+
+### 11.6 操作步骤（本次实际执行的）
+
+```bash
+# 1) 适配器仓库（159.7 MB，16 文件）：curl + 逐文件 sha256/git-blob 校验，写入 HF 缓存布局
+python3 experiments/kev-4b/fetch.py jaredpalmer/kev-4b
+
+# 2) 基座两个分片（9.32 GB）：ModelScope 双流并行，各一条 curl -C -，滚动均值 <0.3 MB/s 自动中止
+python3 experiments/kev-4b/fetch.py Qwen/Qwen3.5-4B-Base --source modelscope --only 'model.safetensors-00001-of-00002.safetensors' &
+python3 experiments/kev-4b/fetch.py Qwen/Qwen3.5-4B-Base --source modelscope --only 'model.safetensors-00002-of-00002.safetensors' &
+
+# 3) 基座其余 11 个小文件（23.0 MB）：必须走 HF（ModelScope 的 .gitattributes 与 HF 不同，见上）
+python3 experiments/kev-4b/fetch.py Qwen/Qwen3.5-4B-Base --source hf --skip 'model.safetensors-*'
+```
+
+`fetch.py` 可重复运行：已完成的 blob 直接校验跳过，未完成的 `<sha256>.incomplete` 由 `curl -C -` 续传。
+原始读数：`experiments/kev-4b/published-state.json`、`experiments/kev-4b/probe-throughput.sh`、
+`experiments/kev-4b/probe-supplemental.sh`、`experiments/kev-4b/fetch*.log`。
+
+### 11.7 端到端验证（全离线）
+
+一次跑完 `bash experiments/kev-4b/verify.sh`，四道闸全过：
+
+| 检查 | 结果 |
+|---|---|
+| 全量重校验 | 两个仓库 `verified_this_pass=True`（适配器 16 文件、基座 13 文件，逐个重算 sha256 / git blob sha1 与 Hub tree 元数据比对） |
+| `resolve_run`（离线） | `jaredpalmer/kev-4b` → `…/snapshots/485ace87…`；`Qwen/Qwen3.5-4B-Base@1001bb4d…` → `…/snapshots/1001bb4d…` |
+| transformers（离线） | `model_type=qwen3_5`、`num_hidden_layers=32`、`vocab=248044` |
+| MLX 装配 + 前向 | 426 个权重张量加载 **16.5–22.0 s**（`backend=mlx`、`dtype=bfloat16`、`device=mps`），一次真实判定返回三个问题的概率 |
+
+服务侧（`HF_HUB_OFFLINE=1`，即完全不需要网络）：
+
+```bash
+$ .venv/bin/python -m kev.serve --run jaredpalmer/kev-4b --port 8008
+[kev: ready; cursor=…]          # 就绪 12.8 s
+```
+
+```json
+// GET /v1/models
+{"models":[{"name":"kev-latest","run":"jaredpalmer/kev-4b","base":"Qwen/Qwen3.5-4B-Base","lora":16,
+            "device":"mps","backend":"mlx","dtype":"bfloat16","temperature":2.1435469250725863, …}]}
+```
+
+```json
+// POST /v1/systemone（一张工单，choice + noul + score 三种题型）
+{"answers":{"department":{"type":"choice","choice":"billing","confidence":0.9666,
+                          "probabilities":{"shipping":0.0112,"billing":0.9777,"returns":0.0111}},
+            "urgent":{"type":"noul","noul":0.2032},
+            "frustration":{"type":"score","score":0.7401,"legend":{"0":"Calm","1":"Frustrated","2":"Very angry"},
+                           "probabilities":{"0":0.3465,"1":0.5669,"2":0.0866},"confidence":0.7834}},
+ "usage":{"input_tokens":117,"output_tokens":181},"latency_ms":1177.4}
+```
+
+三个答案都与题面一致（billing / 不需要当天 / 第 1 级"Frustrated"），且 `temperature` 与 `head.pt` 一致（2.1435）。
+测完即停：`hub stop name=kev-4b-8008`，收尾后 8008 / 8012 / 8014 三个端口均空闲，无残留进程。

+# 本地可安装的 Jev 替代方案调研（面向 `skills/jev-browser`）
+
+- 调研日期：**2026-09-23**（所有 URL 均于该日抓取；每条断言标注来源与来源自身的日期）
+- 目的：找出今天真实存在、可本机安装、且能当作 TypeSafe Jev 替代品的决策模型（decision model），重点是 **sub-1B** 可随 skill 一起分发的选项，并给出一条「一键安装」路径。
+- 读法约定：凡非直接引用来源的推断，均标 `[INFERENCE]`；未经验证的数字不写。

+
+## 0. 结论速览
+
+| 结论 | 内容 |
+|---|---|
+| 唯一真正的 drop-in | **Kev**（`jaredpalmer/kev`，Apache-2.0）明确「serves TypeSafe's public `/v1/systemone` contract」，且官方 `typesafe-sdk` 改 `base_url` 即可用；`Laya` 的 `laya-serve` 声明同样支持 `POST /v1/systemone`（两条独立路线）。 |
+| 唯一可随 skill 分发的 sub-1B 决策模型 | **Kev-0.8B**（LoRA r=16 + pointer head on `Qwen/Qwen3.5-0.8B-Base`，仓库主体 ~113 MB，base 1.76 GB）；上一代 **Kev-0.6B**（Qwen3-0.6B-Base，仓库 ~96 MB，base 1.19 GB）在 Mac 上是更快的一档；原型 **Kev-0.5B**（Qwen2.5-0.5B）作者已标为「prototype，生产请用 0.8B+」。 |
+| 无下载量的兜底 | 未训练的 `Qwen3-0.6B` + **首 token logprob 读法**（JEV-CPU / SemIf 的 trick）可在 ~2.4 GB RAM、纯 CPU、约 1 s/决策跑起来，但需要自己包一层 `/v1/systemone`，且质量是「下限」。 |
+| Apple Silicon 现实 | Qwen3.5 系（0.8B/4B/9B）的 **Gated DeltaNet 层没有 PyTorch MPS kernel**，Kev 在 Mac 上自动改走 **MLX**；Qwen3 世代（0.6B/4B/8B）仍走普通 PyTorch MPS，是 Mac 上「更快的老选择」。 |
+| 质量天花板 | 本机可拿到的最好开源近似是 **Kev-9B**（新来源 locked test 0.852，Jev dev 0.857）与 **Open-Jev-27B-v1.1**（JevBench public 197/231 = 85.28%），但都远超 sub-1B；**Kev-0.8B 域外只有 0.652**。 |

+
+## 1. 我们要匹配的契约（从本仓库代码读出）
+
+来源：本仓库 `skills/jev-browser/lib/typesafe.mjs`、`lib/config.mjs`、`lib/questions.mjs`（本次会话直接阅读，2026-09-23）。
+
+```
+POST {baseUrl}/v1/systemone
+Authorization: Bearer <key>
+Body: { model, state, questions }
+Resp: { model, answers, usage }
+```
+
+- `questions[id]` 只允许三种：`noul`（二值概率）、`choice`（`criteria` 为 2..255 个选项的对象）、`score`（2..10 个有序层级数组，答案概率键为 `"0"`,`"1"`,…）。
+- 客户端解析（`normalizeAnswers`）要求 `answers[id].type === questions[id].type`，并读取 `noul` / `probabilities` / `choice` / `score` / `confidence`；`usage.input_tokens` 决定成本估算（`pricePerMtok` 默认 0.042 USD/Mtok，仅按输入计费）。
+- 构造 `TypeSafeClient` 时 **apiKey 不可为空**（否则抛 `MISSING_API_KEY`），所以挂本地服务时需要 `TYPESAFE_API_KEY=local` 之类的占位值，并把 `pricePerMtok` 设为 0（本地无计费）。
+- 每次请求按 `sha256(model+state+questions)` 缓存；对 408/409/425/429/5xx/529 会重试（默认 2 次）。
+- 负载特征：每个控制步把**一组互相独立的问题**（`goal_done` noul、`blocker` choice、`action` choice、`click_target`/`type_target`/`select_target` choice、`progress` score…）**放在同一次请求里并行评估**，state 是一份观察到的页面（url/title/headings/visible_text/elements）。
+- 因此本地服务必须满足：**一次请求多个问题**、**noul+choice+score 混合**、**返回逐问题分布**、**低延迟**（每步一次调用，`maxSteps` 默认 25）。
+
+> 合规检查（谁满足这条）：Kev ✅（明确声明）、Open-Jev ✅（`Official /v1/systemone request/answer shape; partial API compatibility`）、openjev-sglang ✅（实现了完整 `/v1/systemone`）、Laya ✅（`laya-serve` 声明 `POST /v1/systemone`）、DiffusionGemmaJev ⚠️（vLLM PR 内的**示例 interposer server**，非标准端点）、SemIf ❌（CLI/库，无该端点）、JEV-CPU ❌（自有 `POST /api/decide` 形状）、Jevlike ❌、CUA-S1 ❌（专用表单模型）。

+### 2.4 校准 / 温度处理
+
+- 每个 checkpoint 内置 **一个在 in-distribution dev 上拟合的温度（约 2.1–2.4）**，由 pointer head 在加载时应用；**温度不改变任何答案**，只改概率质量。Kev-9B 新来源上 calibration error 0.106→0.042、confident errors 8.7%→4.0%（≈Jev 的 3.7%），accuracy 不变。[Kev README]
+- `KEV_TEMPERATURE=1.0` 关闭；`scripts/calibrate_checkpoint.py` 给出 out-of-fold（group-disjoint 5-fold）校准误差与 bootstrap 区间（Kev-4B dev：raw 0.075 / out-of-fold 0.020，95% 区间 0.014–0.041，差值区间不含 0）。[Kev README]
+- README 表格里的 accuracy 与 Brier 是 **raw logits**口径；model card 表里的 "as served" 一行才是内置温度口径。混用会读出不一致的数。
+- ⚠️ **merged weights 的坑**（Bespoke Nimble 明示，Kev 未声明）：`The logits from merged weights can be slightly different. We did not check the temperature again on the merged weights.`[Nimble README, 2026-09-23] — 对任何合并 LoRA 的本地部署都是同一类风险。
+- 关于「校准只靠一个温度」的边界，Kev 作者自己写：固定温度无法重排次序，所以 5% 误差预算下可自动化比例（0.45–0.57）仍低于 Jev 的 0.70。[Kev README, Limitations]

+| 另一处口径 | Kev-0.8B card 写 **「a five-question request takes ~0.33 s in bf16 on an M5（Kev-0.6B: 0.12 s）」**，并把根因写成「DeltaNet kernels have no MPS implementation」。⚠️ 与 README 的 149 ms 口径不一致（0.33 s vs 0.149 s），来源未解释，**上线前必须自测**。 |

+### 2.7 Kev 的已知局限（对我们最相关的四条）
+
+1. **训练上下文 ≤384 state token**（state+question 共 1,024），服务允许 8,192 state+question —— 长页面（我们的 `visible_text` + elements）会落到训练分布外；作者把「更长训练上下文」列为 planned fix（issue #48）。
+2. **服务器一次只处理一个请求**（有 state 前缀缓存，不跨调用方 batching）。
+3. 选项顺序会改变答案（isolation 只保证问题之间互不可见）。
+4. 知识类问题（MMLU 0.74 vs Jev 0.90；MMLU-Pro 0.52 vs 0.84）基本由 base 决定，训练补不上。
+5. 需要 `transformers >= 5.17`、`peft >= 0.21`（0.8B card 明示）。

+- OpenJev（SemIf）作者的定性：**「The first thing to establish is that OpenJev is not the official open-source version of Jev. TypeSafe has not released the model weights」**。[dev.classmethod.jp 转述, 2026-09 抓取] ＋ SemIf README 自述「reproduces that interface pattern; it does not reproduce Jev's undisclosed model or training」。
+- OpenJev 的概率**未经校准**（README：`Probabilities are conditioned on the supplied options … and are not calibrated estimates of correctness`），其 `confidence = 1 - H/log(K)` 是熵式指标。SemIf 提供 per-workload temperature scaling，可作为对照实现（authored144 ECE 0.068→0.038 @T=1.23；WANLI 0.208→0.069 @T=2.50）。
+- Open-Jev 的推理性能记录：客服场景本地 HTTP 中位 **85.03 ms** vs Jev HTTPS 295.26 ms；但 1,024 state token + 32 候选时 **1015.90 ms** vs Jev 301.37 ms；CUDA prefix caching 在 11 个工作负载中有 9 个超出概率容差，故默认关闭。[Open-Jev README, 2026-09-23]

+
+## 4. 未训练 sub-1B + 「prompt + 首 token logprob」方案
+
+这条路线不训 LoRA/head，只把决策问题渲染成「下一个 token 是 A/B/C…」的 prompt，然后从**最后一个位置的 logits** 里只取选项槽位做 softmax。参考实现见 JEV-CPU README「How a decision is read from logits」（CPU 版 SemIf，2026-09-19）：
+
+1. 每个选项映射成一个大写字母，prompt 以 assistant 头结束（`add_generation_prompt=True`、`enable_thinking=False`）；
+2. `_slot_ids()` 校验每个字母是**单 token** 且 round-trip（`decode(encode("A")) == "A"`），保证槽位干净、不被空白合并；
+3. **一次前向**：`logits = model(**inputs, use_cache=False).logits[:, -1, :]`；
+4. `softmax(logits[slot_ids])` → 每个选项一个概率，取 argmax 即答案。
+
+同源方法在服务端的等价实现见 openjev-sglang：`max_new_tokens=1` + `token_ids_logprob` 拉取所有答案标签的 logprob，再做 stable softmax 归一化；标签用 `A`–`Z` 及验证过的 `AA`,`AB`,… 组合，启动时对照 tokenizer 全量校验（因为 Qwen 会把 `10`/`64` 切成多 token）。[openjev-sglang README, 2026-09-23]

+| **SmolLM2-360M / -Instruct** | 360M 级 | apache-2.0 | 有 `SmolLM2-360M-Instruct-GGUF`（仅 q8_0）；原模型带 ONNX（含 `transformers.js` tag） | 无决策任务公开证据 → `[INFERENCE]` 只能当「量级参考」 |
+| **SmolLM3-3B / -3B-Base** | 3B | apache-2.0 | 有 ONNX | ⚠️ **SmolLM3 没有 360M 版本**（HF 检索只有 3B）；需求清单里的「SmolLM3-360M」应是把 SmolLM2-360M 记错了 |
+| **Gemma-3-270m** | 270M | `license:gemma`（自定义、**HF 上 `gated: manual`**） | `unsloth/gemma-3-270m-it-GGUF`（含 IQ/UD 多档） | 无决策任务公开证据；许可证需人工审批 → 不适合「随 skill 分发」 |
+| **LFM2.5-350M** | 350M | `license: other`（LFM Open License） | **官方** `LiquidAI/LFM2.5-350M-GGUF`（BF16/F16/Q4_0/Q4_K_M/Q5_K_M/Q6_K/Q8_0 + QAD） | 有第三方 RLCD/约束解码衍生版（`notnotsamuel/LFM2.5-350M-RLCD`，tag 含 `apple-silicon`、`structured-generation`）；无中立决策基准 |

+| **Qwen3.5-2B** | 2B 级 | apache-2.0 | 社区 GGUF | Open-Jev-2B 的 pinned base（`--revision 15852e8c…`），JevBench 150/231 |
+
+### 4.2 这条路的校准现实
+
+- 未训练模型给出的选项概率**直接来自 softmax，未经校准**；需要用 labeled 切片拟合温度。可直接抄 SemIf 的做法（per-workload ECE/温度表）与 JEV-CPU 的 `option_logits + probabilities` 输出契约。
+- JEV-CPU 自己记录了 0.6B 的**一致性问题**：loan/credit 示例里模型正确判定「high risk」却仍倾向「approve」，「an inconsistency that larger models resolve」。
+- 结论：sub-1B 未训练模型的定位是**离线兜底 / 消融对照**，而不是生产替代。

+| **llama.cpp / `llama-server`** | 任何有 GGUF 的模型（Qwen3.5-0.8B、LFM2.5-350M、MiniCPM5、Gemma-3-270m…） | ⚠️ 需自写 adapter | 支持 `n_probs`（>0 时响应带 `completion_probabilities`，含每 token 的 `top_logprobs`；`post_sampling_probs` 给采样链后概率；`temperature<0` 时 greedy 但概率仍按 softmax 计算）；缺点是**没有**「指定 token id 列表」的原生入参（vLLM 有 `logprob_token_ids`），只能取 top-N 再筛选项字母 |
+| **Ollama** | 同上（模型以 GGUF 分发） | ⚠️ 需自写 adapter | `/api/generate` 与 `/api/chat` 都接受 `logprobs: bool` + `top_logprobs: int` 并返回 `Logprob`/`TokenLogprob`（官方 OpenAPI schema）；但社区报告 **OpenAI 兼容端 `/v1/chat/completions` 不返回 logprobs**（GitHub issue, 2026-01-07） |
+| **LM Studio** | 同上，开发者模式起本地 REST server（官方文档） | ⚠️ 未确证 | 本次抓取的官方 OpenAI 端点文档页**未出现 logprob 字样**；2024-08 的 issue #60 记录「logprobs 未在响应中返回」。`[INFERENCE]` 现在可能已支持，必须实测 |
+| **transformers.js** | 浏览器/Node 内跑 ONNX（SmolLM2 等带 ONNX 的模型） | ❌ 不适用（浏览器内算力与内存受限；且其文档化的 text-generation 输出是文本） | 需要的「读下一 token 的选项 logits」不是 pipeline 的公开输出；`[INFERENCE]` 要自己用底层 forward 取 `logits`。SemIf 的浏览器 demo 用的是**量化 GGUF**（Q8_0/Q4_K_M），说明浏览器路径实际走的是别的推理栈 |
+| **自写 Python（PyTorch/MLX）** | 一切；这就是 JEV-CPU / SemIf / Kev 内部的做法 | ✅（最灵活） | 需要自己维护 HTTP 层；但换来对 `/v1/systemone` 的完全控制（多问题并行、置信度、per-question 隔离） |
+
+补充：CoreML/ANE 路线已有人趟过（CUA-S1-Forms → `FluidInference/cua-s1-forms-coreml`，含 fp16/int8/int4 与 ANE profiling/verification 报告），说明「sub-MB 级 option-attention 模型上 Apple Neural Engine」在 2026-09 是可行的。[HF `FluidInference/cua-s1-forms-coreml`, lastModified 2026-09-22]

+
+- `docker compose up -d --build` + `uv run --frozen --directory integrations/kev-mcp python global_install.py install`（Busy-Office/kev-agent-kit，Apache-2.0），把本地 Kev 作为 MCP 工具接进 Claude Code / Codex / Antigravity，API 在 8008、playground 在 8009；注意它**默认拉 0.5B checkpoint**。
+- 想按自己的问题集微调：Kev 提供 `--init_from`（从已发布 checkpoint 起训，而不是从 base）与可选的 agent skill `npx skills add jaredpalmer/kev@kev-finetune`。作者数据点：从 base 起训在 836 条支持工具决策上只拿 0.33（发布模型 0.84），而 `--init_from` 保住 0.83 并在新域到 0.88。
+
+### 6.5 接入本 skill 时的具体风险与对策
+
+| 风险 | 依据 | 对策 |
+|---|---|---|
+| 每步 5–8 问、最多 25 步，sub-1B 的 0.652 OOD accuracy 会**累积**成任务级失败 | Kev-0.8B OOD 0.652；本仓库 `maxSteps` 默认 25 | 本地模式下降 `maxSteps`、对 `choice` 用 `confidence` 阈值、把「不确定」交给已有 `blocker`/`wait` 路径；并在真实页面上做 A/B 打分（同一 state 同时问托管 Jev 与本地模型） |
+| state 很长（`visible_text` + elements）超出训练上下文 | Kev 训练 ≤384 state token、服务 8,192；issue #48 | 截断/摘要 state，或只把本地模型用在短 state 的判定（如 `goal_done`/`blocker`） |
+| 概率口径混用导致阈值失效 | README 表 = raw logits，card "as served" = 内置 T；Bespoke 明确 merged weights 未复测温度 | 固定用「服务默认温度」口径，并在本仓库侧记录 `provider` 与温度设置 |
+| 服务器串行、无并发 | Kev README：「handles one request at a time」 | 单步串行调用本身与我们的用法一致；不要并行发多请求 |
+| Mac 延迟口径不一致 | card 0.33 s vs README 149 ms（同为 M5） | 上线前在目标机器跑 `scripts/mlx_parity.py` 与真实 5 问请求自测 |
+| 许可 | Kev/Qwen3.5 为 Apache-2.0；Gemma-3-270m 是自定义 gated 许可；LFM2.5 是 `license: other`；Nimble 未见 license 声明 | 随 skill 分发的默认档只用 Apache-2.0 资产；其他档必须显式提示用户确认许可 |
+
+---
+
+## 7. 未决问题 / 需要实测的清单
+
+1. **Kev-0.8B 在 M5 上的真实延迟**（card 0.33 s vs README 149 ms / 28 ms 缓存）——来源互相矛盾，必须自测，包括 MLX 与 `KEV_BACKEND=torch` 两条路径。
+2. **本 skill 的真实问题分布上的准确率**：Kev 的所有公开套件都不是「网页元素选择」任务；需要把 `judge` 的 state/questions 采样一批，同时打托管 Jev 与本地 Kev-0.8B/4B，比较 top 答案一致率与 Brier。
+3. **长 state 退化曲线**：把 `visible_text` 从 300 加到 4,000 token，测 Kev-0.8B/4B 的答案漂移（训练上下文 384/1,024 是硬边界）。
+4. **跨请求的 state 复用收益**：Kev 有 prefix cache（`KEV_PREFIX_CACHE`），但我们的 state 每步都会变（`last_action`/`previous_page`），缓存命中率待测。
+5. **Laya 作为第二 drop-in 的可行性**：`laya-serve` 声称 `POST /v1/systemone`，但未见其 response schema 与 TypeSafe 字段逐项对齐，需实测 `normalizeAnswers` 能否吃下（尤其 `choice` 的 `probabilities` 键名与 `confidence`）。
+6. **LM Studio / transformers.js 的 logprob 能力**：官方文档未确证，若要用必须实测。
+7. **Bespoke Nimble 的 license**（GitHub API 取 metadata 403，README 未声明）——在法务确认前不能进推荐默认档。
+8. **是否有真正「训练过、sub-1B、非 Qwen」的决策模型**：本次调研中未发现（除 CUA-S1 这类领域专用与 421M 的 Laya）；`[INFERENCE]` 当前 sub-1B 通用决策的最优解仍是 Kev 家族。

+
+## 9. Laya / Open-Jev 深挖（第二 drop-in 候选）
+
+本节只回答两件事：(a) 它们能否作为与 Kev 并列的第二个本地后端；(b) 我们的 `normalizeAnswers`（`skills/jev-browser/lib/typesafe.mjs`）能否**不改代码**吃下它们的响应。
+
+### 9.1 Laya（`github.com/NandhaKishorM/laya`，Apache-2.0）
+
+#### 9.1.1 它到底是什么
+
+**是训练出来的非自回归决策模型，不是套在生成式模型外面的 wrapper。** 证据：
+
+- 自述 `Multilingual, non-autoregressive System 1 decision engine … trained with reinforcement learning against strictly proper scoring rules (RLCD), with a router that picks the right checkpoint per request`；单次前向 33 ms 量级，**不生成任何 token**。[Laya README, 2026-09-23 抓取]
+- HF 卡片标签 `laya / system-one / calibrated-decisions / rlcd / classification / routing / scoring / guardrails / moderation / reinforcement-learning / commercial-use`，`library_name: transformers`、`auto_model: AutoModel`（即用 `AutoModel` 前向取选项分数，不是 `generate()`）。[HF `convaiinnovations/laya` API, lastModified 2026-09-23]
+- 结构 = 预训练 encoder（ModernBERT-large / mmBERT-base）+ 在 encoder 之上加的自定义 option-scoring 层；权重里带 `rl_agent_config.json`（温度等配置随 checkpoint 走）。[HF 仓库文件表 + `laya/agent.py` 源码, 2026-09-23]
+- Latent.Space 的第三方描述与之一致：`421M params, ModernBERT-large encoder with two added transformer layers that score user-supplied options, PPO over sequence embeddings`，并指出 `confidence is entropy-based, not calibrated`。[latent.space, 2026-09-19]（注意：Laya 自己后来的文档称温度是拟合出来的，见 9.1.3 的校准表。）
+
+#### 9.1.2 全部公开 checkpoint（三者都 <1B）
+
+| checkpoint | HF repo | 参数量（`safetensors` 字段） | 仓库 usedStorage | encoder / ctx | license | 是否 sub-1B |
+|---|---|---|---|---|---|---|
+| `laya`（英文档，含 `typed-decisions/`、`multilingual/` 子目录） | `convaiinnovations/laya` | **421,293,830**（F16 421,293,827 + F32 3） | 2,366,100,536 B（≈2.37 GB，含三个子目录） | ModernBERT-large，ctx 512 | apache-2.0 | ✅ |
+| `laya-multilingual` | `convaiinnovations/laya-multilingual` | **321,908,998**（F16 321,908,995 + F32 3） | 678,198,702 B（≈678 MB） | mmBERT-base，ctx 1024 | apache-2.0 | ✅ |
+| `laya-typed-decisions` | `convaiinnovations/laya-typed-decisions` | 未从 API 取到（README 表列 421M） | 未取 | ModernBERT-large，ctx 1024 | apache-2.0 | ✅（README 标 421M） |
+
+三者的 ctx/用途出自 README 表：`laya` 421M/512「English」、`laya-multilingual` 322M/1024「100+ languages, 2x faster」、`laya-typed-decisions` 421M/1024「the typed-decisions workflows」。[Laya README, 2026-09-23]
+Router 行为：默认只常驻 `english` + `multilingual` 两个（`max_loaded=2`），`max_loaded=1` 会在每次语言切换时重建（作者实测 CPU 中位 7.4 s、T4 10.3 s 重载）；`typed-decisions` **不会**被自动路由选中，除非显式 `--auto-task`/`model=`。[Laya README]
+
+#### 9.1.3 质量数字 vs Jev（含作者自己声明的比较边界）
+
+BENCHMARKS.md 开头的免责声明必须一起引用：**`Jev figures are third-party published, never measured here — no TypeSafe API access — so sample sizes and prompts differ; treat them as indicative.`**[Laya `BENCHMARKS.md`, 2026-09-23]
+
+Headline：
+
+| | Laya | Jev（published） |
+|---|---|---|
+| typed-decisions（2,000 decisions） | **0.766** | 0.727 |
+| AG News（4 labels） | **0.953** | 0.910 |
+| DAIR Emotion（6 labels） | **0.600** | 0.480 |
+| ECE after temperature fitting | **0.081** | 0.246 |
+| p50 latency, 1 question (T4) | **32.8 ms** | 236–276 ms |
+
+但同一份文档也给出反面证据，必须一并看：
+
+- **0.766 只属于 `laya-typed-decisions`，且是该 benchmark 自己的训练 split**；基础 checkpoint 在该 benchmark 上**低于多数类基线**（`laya` 0.361、`laya-multilingual` 0.342、majority 0.461、Jev 0.727、teacher ceiling 0.735）。作者原话：`All of the capability on this benchmark comes from fine-tuning.` + `Near chance on typed-decisions zero-shot`。[BENCHMARKS.md]
+- **banking77 是明显败仗**：0.425 / 0.425 / **0.492** vs Jev 0.870；作者归因为架构（choice 的选项共享固定 `head_max_len` 预算，77 个标签每个只剩约 4 token），并建议 `Keep choice questions under ~20 options`。[BENCHMARKS.md]
+- 主题级真实数据（各 400 例）：邮件 spam 0.993 / phishing 0.993（均在训练混合里，ECE≈0.01）、LLM guardrails 0.708–0.762（held out）、**审核 toxicity 仅 0.530（macro-F1 0.400，held out）**、支持工单 10 路 0.502–0.522。[BENCHMARKS.md]
+- 多语：51 语 MASSIVE intent 上 `laya` macro 0.2269、`laya-multilingual` 0.3661（随机 0.050）；英文 doc 在非英文上**崩得很有自信**（Khmer **0.000 accuracy at 0.952 confidence**），所以路由必须在 forward 之前做。[BENCHMARKS.md]
+- 校准：**两个 checkpoint 出厂都过度自信**（`laya` ECE 0.466、`laya-multilingual` 0.314，且后者**没有**拟合温度）；按 (问题类型, 选项数) 重新拟合温度后降到 0.081 / 0.106。另有 #42 之后的温度 clamp `[0.5, 5]`，因此旧 CPU sweep 的 ECE 列已过期。[BENCHMARKS.md]
+- 选项顺序稳健性：0.150 / 0.040 / 0.000（三个套件），Jev 为 0.13 —— 20 选项时比 Jev 更不稳。[BENCHMARKS.md]
+
+#### 9.1.4 安装 / 服务 / 运行时
+
+```bash
+pip install "laya[serve]"                    # 加 fastapi + uvicorn
+LAYA_DEVICE=cuda LAYA_PRELOAD=1 laya-serve    # 默认绑 0.0.0.0:8000，预加载全部 3 个 checkpoint
+# 或者：nix run .#laya-serve（flake，含 CUDA torch 二进制）
+# 或 Docker quickstart：docs/docker.md
+```
+
+- 运行时：**Python 3.10+**（由 `huggingface_hub` 1.x / `transformers` 5.x / `torch` 2.14 决定），**PyTorch**（不是 Node、不是 GGUF 栈）；CPU 可跑，GPU 更快。[Laya README]
+- 环境变量（`laya/serve.py` 源码表格）：`LAYA_HOST`(0.0.0.0) / `LAYA_PORT`(8000) / `LAYA_DEVICE`(auto) / `LAYA_PRELOAD`(1) / `LAYA_MODELS` / `LAYA_THREADS`（CPU 时限制 torch intra-op 线程，**别超过物理核**）/ `LAYA_AUTO_TASK`(0) / `LAYA_API_KEY`（设置后要求 Bearer）/ `LAYA_LOG_LEVEL`。[`laya/serve.py`, 2026-09-23]
+- 服务端只有两个路由：`GET /health`（返回 `{status, loaded, device}`）与 `POST /v1/systemone`；`import laya.serve` 本身不碰 GPU（重依赖延迟导入）。[`laya/serve.py`]
+- macOS：README 的安装章节同时给 macOS/Linux（venv + pip），但**没有 Mac/MPS 的实测数据**，`LAYA_DEVICE` 需自行指定；`[INFERENCE]` Apple Silicon 上应先试 `LAYA_DEVICE=mps`，不行再退 CPU（`LAYA_THREADS=物理核数`）。已知的 CPU 参考值：预加载后在笔记本 Ryzen 9 6900HX 上单问 **193–464 ms**；GB10 上单问 p50 100.2 ms（其中约 93 ms 是固定开销）、50 问 443.1 ms、每多一问约 +7.0 ms。[BENCHMARKS.md]
+- ⚠️ 默认监听 **0.0.0.0**（与 Kev 默认 127.0.0.1 不同）：本地试用时建议显式 `LAYA_HOST=127.0.0.1`。
+
+#### 9.1.5 `/v1/systemone` 的精确 schema（源码级）与我们客户端的兼容判定
+
+响应由 `laya/agent.py::system_one`（`predict = system_one`）产生，`laya/serve.py` 直接把它的返回值当响应体（额外多一个 `routing` 字段）：
+
+| 类型 | 返回字段（源码原文） |
+|---|---|
+| 顶层 | `{"model": "laya-rl-agent", "answers": {...}, "usage": {"input_tokens": n_tokens, "output_tokens": 0}}`（经 serve.py 再加 `routing`） |
+| `choice` | `{"type": "choice", "choice": <选项 key>, "probabilities": {<key>: 4 位小数}, "confidence": <float>, "action": {"act_probability": <float>}}` |
+| `score` | `{"type": "score", "score": <期望值>, "legend": {"0": <描述>, …}, "probabilities": {"0": <4 位小数>, …}, "confidence": <float>, "action": {...}}` |
+| `noul` | `{"type": "noul", "noul": <P(true)>, "confidence": <max(p1, 1-p1)>, "action": {...}}` |
+
+（来源：`https://raw.githubusercontent.com/NandhaKishorM/laya/main/laya/agent.py`，2026-09-23；`confidence_from_probs`、`action` 均为额外字段。）
+
+对 `skills/jev-browser/lib/typesafe.mjs::normalizeAnswers` 的逐项判定：
+
+| 我们的检查 | Laya 是否满足 | 说明 |
+|---|---|---|
+| `answers[id].type === questions[id].type` | ✅ | 三种类型都带 `type` |
+| `noul` 为 0..1 的数 | ✅ | `noul` 字段是 P(yes)；我们自行补 `probabilities:{true,false}`，Laya 不返回该 map 也没关系 |
+| `choice` 的 `probabilities` 覆盖 `criteria` 的所有 key | ✅ | 按 `q["crit"]` 的原 key 输出；缺失 key 我们本来就会补 0 |
+| `choice.choice` / `confidence` | ✅ | 两者都在 |
+| `score` 的 `probabilities` 键为 `"0".."n-1"` | ✅ | Laya 用 `str(i)`，与我们 `criteria.map((_, i) => String(i))` 完全一致 |
+| `score.score` / `legend` | ✅ | 都在（`legend` 我们不强制读） |
+| 多余字段（`action`、`routing`） | ✅ | 我们只挑已知键，忽略其余（Laya 自述其 Haskell 客户端 `hs-jev` 同样「ignores the rest」） |
+| 概率归一化 | ⚠️ 无需处理 | Laya 把概率**四舍五入到 4 位小数**，和不一定精确为 1；我们的客户端不做归一化、也不因为和不等于 1 抛错，所以可接受（不要在此之上再加「概率和必须为 1」的断言） |
+| 空 `questions` | ⚠️ 不会发生 | Laya 对空问题集返回空 answers 而不报错；我们本地已先在 `validateQuestions` 拦掉空问题集 |
+| 鉴权 | ✅ | `LAYA_API_KEY` 未设置时不校验，我们照发 `Authorization: Bearer <key>`；设置后也匹配 |
+| `model` 字段 | ✅ | 我们默认发 `jev-latest`；Laya 的 `_resolve_model` 对未知名字**当作「未指定」并自动路由**（源码注释明说 Jev 客户端的 model 字段预期 miss），不会 400 |
+| 错误码 | ✅ | body 非对象或缺 `questions` → 400；模型/tokenizer 异常 → 422（我们视为不可重试的 `TypeSafeError`） |
+
+**结论：`laya-serve` 的响应可以不改我们任何客户端代码直接用。** 接入成本不在 schema，而在「Mac 实测延迟 + 在真实 state 上的答案一致率」——见 9.4。
+

+### 9.3 SemIf 与 kev-agent-kit 各一行
+
+- **SemIf（MIT）**：**是模型引擎，不是模型**——它把「渲染 prompt + 读选项 logits」这套逻辑做成 Python 包与 `semif-score` CLI，**在进程内加载模型**（PyTorch/CUDA、`--device mps`、`--backend mlx`、或 `--backend llamacpp --gguf …` 走本地 GGUF）；没有 HTTP 服务、没有 `/v1/systemone`，所以**不能**用 baseUrl 指过去，但它可以做我们要自己写的那层 adapter 的参考实现与校准脚本（per-workload 温度拟合）。运行时：Python 3.10+，`pip install -e '.[test,mlx]'` 或 `.[test,llamacpp]`。[SemIf README, 2026-09-23]
+- **kev-agent-kit / kev-mcp（Apache-2.0，Busy-Office）**：也不实现模型——它把上游 `kev.serve` 装进 Docker（`Dockerfile.cpu` + `compose.yaml`），再提供一个 **stdio MCP server**（`integrations/kev-mcp`，3 个 MCP 工具）去查询**本地 Kev API（默认 `http://127.0.0.1:8008`）**，并附带把配置写进 `~/.codex/config.toml`、`~/.claude.json`、`~/.gemini/config/mcp_config.json` 的全局安装器；运行时要求 Docker Compose + uv + Python 3.12+ + Node 20+，首次启动下载 **0.5B** checkpoint，其徽章与卡片覆盖 0.5b/0.6b/4b/8b（即绑定的是 Qwen3 世代）。[repo README, 2026-09-23；glama.ai 的 kev-mcp 条目]
+  可复用点：要么直接用它那套 compose 作为 Kev 宿主，要么（更干净）继续用上游 `kev.serve`——两者都是同一个 HTTP 契约，我们的客户端只看 baseUrl。

+# Local GGUF backend — measured results
+
+First-token logprob readout on top of `llama.cpp`: the question is rendered with labelled options,
+exactly one token is generated, and the probability mass on each option label at that position is
+the answer. No training, no text generation, no output parsing, no API key.
+
+Default model is now **Qwen3.5-4B Q4_K_M**; the 0.8B stays as a selectable, faster/weaker entry.
+Full ranking and caveats: `results/local-models-4b.md`.
+
+- Machine: Apple M3 Max / 48 GB / macOS 25.6.0 arm64, Node 26.9.0 (no Python involved).
+- Ship model: `Qwen3.5-4B-Q4_K_M.gguf` — 2,740,937,888 B, sha256 `00fe7986ff5f6b463e62455821146049db6f9313603938a70800d1fb69ef11a4`,
+  from `unsloth/Qwen3.5-4B-GGUF` (`llama-server /props` reports `model_ftype = Q4_K - Medium`, arch `qwen35`).
+- Reference model: `Qwen3.5-0.8B-Q8_0.gguf` — 811,843,840 B, sha256
+  `0ad885ffd4bb022fc4f0d33a3308fa108ef8613159d3b3a67e23abca056b7a6c`, from `unsloth/Qwen3.5-0.8B-GGUF`.
+- Server: `llama-server` (Homebrew `llama.cpp` 0.4.0, Metal via MPS), **`-c 16384`** — see *Context size*.
+- Product copy of this provider: `skills/jev-browser/lib/local.mjs`, one command in
+  `skills/jev-browser/bin/jev-local.mjs`. The code here and the code there are the same algorithm.
+
+## Accuracy — 20 graded items (ground truth known by construction)
+
+| model | all (20) | browser (15) | noul (5) | action + click_target (5) |
+| --- | --- | --- | --- | --- |
+| **Qwen3.5-4B Q4_K_M (ships)** | **16 · 0.800** | 12 · 0.800 | 4 · 0.800 | 2 · 0.400 |
+| Qwen3.5-0.8B Q8_0 (reference) | 10 · 0.500 | 7 · 0.467 | 3 · 0.600 | 1 · 0.200 |
+| "always answer the option listed first" | 11 · 0.550 | 9 · 0.600 | 2 · 0.400 | 2 · 0.400 |
+| hosted Jev (ceiling, same items) | 19 · 0.950 | 14 · 0.933 | 5 · 1.000 | 5 · 1.000 |
+
+The 4B is the first local candidate to clear the positional prior (+5 items) and to be close enough
+to hosted Jev to be useful for short decisions. Its errors on the graded set: `ddg-click-target-aapl`
+(see caveats), `ddg-typed-action`, `github-login-action`, `bq-penguins`.
+
+Readout quality on the 4B: captured label mass **mean 0.9407 / min 0.7958**, **0 non-single-token
+labels** (the alphabet verification skipped everything the tokenizer splits). One 100-option item
+lost 32 tail labels outside the 512-candidate window.
+
+**Rotation (text, not position).** Rotating the option list while keeping the labels: on the
+100-option `wiki-login-click-target` the 4B hit the exact expected element at every rotation
+(k=0/3/7 → `e8`/`e5`/`e1`, P≈0.99). The 0.8B instead kept answering inside the first few slots
+(`e1`/`e2`/`e4`/`e6`) — i.e. the 4B reads the option text, the 0.8B reads position.
+
+**Confidence is usable as an abstention signal on the 4B** (it was not on the 0.8B): 12 choice/score
+answers, mean confidence 0.516; wrong answers average 0.233 (most confident wrong: 0.598). Filtering
+at `confidence ≥ 0.5` keeps 8/12 answers with 7/8 correct; at `≥ 0.7`, 4/12 with 4/4.
+
+## Latency — one real browser step, 5 questions
+
+State 16,111 B — the skill's own first-step question set (`goal_done` noul, `blocker` 6 options,
+`action` 5, `click_target` 55, `select_target` 3); 13,729 prompt tokens cold, 6,859 warm. Numbers
+below are from a clean re-run with nothing else running (a concurrent-download run produced the same
+answers, 13.8 s wall).
+
+| model | cold | warm (prefix cache hot) | RSS |
+| --- | --- | --- | --- |
+| **Qwen3.5-4B Q4_K_M** | **18,298 ms** | **9,002 ms** | 3,362 MiB |
+| Qwen3.5-0.8B Q8_0 | 2,933 ms | 1,745 ms | not measured |
+
+Per question, 4B warm: `goal_done` 703 ms · `blocker` 815 ms · `action` 705 ms ·
+**`click_target` 6,135 ms** · `select_target` 630 ms. Per question, 0.8B warm: 151 / 159 / 127 /
+1,165 / 132 ms. The whole step is the repeated prefill of the state per question, and `click_target`
+dominates because it lists 55–100 options. The 0.8B through the skill itself
+(`jev-browser judge` against `TYPESAFE_BASE_URL`) was 2,673 ms wall for the same questions with
+`normalizeAnswers` consuming the answers unchanged (27/27 checks); local tokens cost **$0**.
+
+## Context size
+
+A rendered prompt is dominated by the option list: with the skill's default
+`observation.maxCandidates` of 100, `click_target` is about **11.7k tokens** (11,748 measured on the
+55-option fixture step). The launcher now spawns `llama.cpp` with **`-c 16384`** (its `--ctx`
+default) for that reason; at `-c 8192` llama.cpp hard-fails the request with
+`400 request (11748 tokens) exceeds the available context size (8192 tokens)`
+(`exceed_context_size_error`), so 8192 is not usable with the default candidate count. Starting
+`llama-server` by hand is no longer required.
+
+## Where it breaks
+
+- Long element lists stay the weak spot: even at 4B, `click_target` costs ~6 s and the `action`
+  slice is 2/5 — it is the question that also dominates latency.
+- Free-form `type_value` and pass-`goal_done` judgments on long states were the 0.8B's worst cases;
+  the 4B reads both correctly on the fixtures (goal_done 0.006 for an unmet goal) but they remain
+  the least tested.
+- Anything visual: the state is text only.
+- Product guard: when the readout cannot find the option labels at all (label not a single token,
+  candidates truncated) the mass drops and the server answers HTTP 422 `LOW_LABEL_MASS` naming the
+  question instead of guessing.
+
+## Ranking and what is still unmeasured
+
+`results/local-models-4b.md` is the full ranking. Two caveats from it are load-bearing:
+
+- Candidates 2 and 3 (`Qwen3-4B-Instruct-2507`, `gemma-3-4b-it`) never finished downloading — the
+  link collapsed to ~10–25 KB/s with bursts — so their accuracy **and** their drivability through
+  the render path (chat template via `/apply-template`) are unexercised. No download is running now;
+  the retry script is `/tmp/jev-ceiling/fetch-4b.sh` (start with `hub`, then
+  `bash /tmp/jev-ceiling/run-candidate.sh <slug> 8100`).
+- `ddg-click-target-aapl`'s ground-truth label is debatable: the hand label is `e1` (investing.com,
+  `in_viewport=false`), while hosted Jev and the 4B both pick `e15` (Yahoo Finance AAPL quote page,
+  in viewport). Every model is therefore scored down by up to one item on that question.
+
+`Qwen3-0.6B` (11/20 on the same set, slower than the 0.8B) is not shipped.

Between 1897 and 1907, Mallon worked at several homes; residents at four of them contracted typhoid. In 1907, she was forcibly quarantined at Riverside Hospital, but was freed in 1910, promising not to work as a cook. A further outbreak at the Sloane Maternity Hospital, where she was working, resulted in 25 cases and two deaths in early 1915. She was again confined, remaining so until her death in 1938. Her nickname became a term for anyone who spreads disease. Mallon's case raises questions about the balance between individual liberty and public health. No other carrier of typhoid was confined for as long as she was. Her story has been reevaluated, particularly during outbreaks of HIV/AIDS, tuberculosis, and COVID-19. (Full article...)

Between 1897 and 1907, Mallon worked at several homes; residents at four of them contracted typhoid. In 1907, she was forcibly quarantined at Riverside Hospital, but was freed in 1910, promising not to work as a cook. A further outbreak at the Sloane Maternity Hospital, where she was working, resulted in 25 cases and two deaths in early 1915. She was again confined, remaining so until her death in 1938. Her nickname became a term for anyone who spreads disease. Mallon's case raises questions about the balance between individual liberty and public health. No other carrier of typhoid was confined for as long as she was. Her story has been reevaluated, particularly during outbreaks of HIV/AIDS, tuberculosis, and COVID-19. (Full article...)

+
+> **† Kev 对照行** —— 产物 `experiments/kev-4b/`（runner + 逐题原始 JSON + README）；同一 20 条自明真值
+> ＋同一真实 fixture 一步，走 skill 自身的 `/v1/systemone` 客户端路径（hosted Jev 用的同一条），
+> `--run jaredpalmer/kev-0.8b` 已由 preflight 逐字核对 ⇒ 不可能静默换模型。
+> - **两处结构性不可答（HTTP 422，不是答错）**：`ddg-click-target-aapl` 与真实 fixture 一步的
+>   `click_target` 都被 `branch too long: 4700 tokens with a 6407-token state (row limit 8192)` 拒绝。
+>   上限来自 `kev/model.py:15 SERVE_MAX_STATE, SERVE_MAX_BRANCH = 8192, 8192`（行 = state + 单分支），
+>   **无 env 开关**。GGUF 侧同一 fixture 也是 11,748 tokens，靠 `llama.cpp -c 16384` 解决；Kev 没有
+>   对应旋钮 ⇒ 20 条里只有 **19 条可答**（14/19 = 0.737）。`action+click` 5 题里那 2 条 click_target
+>   实际 1 条可答（`wiki-login-click-target` 命中 e9）。
+> - **noul 不是"卡在 0.5"，而是按 state 长度分裂**：短 passage **5/5** 且极锐（0.0070 / 0.1312 vs
+>   0.9816 / 0.9859，separation **+0.936**）；浏览器 state 上**反向且贴中线**（separation **−0.120**）——
+>   同一 fixture state 的 `goal_done` = **0.6952（假成功）**，而 GGUF 4B 在同一 state 上是 **0.006**；
+>   两条 `submit_after_type` = **0.4594 / 0.4627**（离 0.5 只有 0.04，其中判"对"的那条正是靠 0.5 阈值蒙对）。
+> - **choice 概率贴中线**：11 个 choice/score 答案里 3 个 top1−top2 ≤ 0.05（`ddg-typed-action` 0.029、
+>   `github-login-type-value` 0.020、`wiki-progress` 0.0016）；`wiki-progress` 归一化熵 **0.973** 近均匀
+>   （p=[0.14,0.27,0.30,0.30]，score=1.749 只因 ±0.5 落窗得分）；`action` 0.498/0.239/0.163、
+>   `blocker` 0.459/0.240/0.177。
+> - **概率按常规求和**：11 个 choice/score 答案 Σp mean 1.0000 / min 0.9997 / max 1.0001，0 个越界
+>   —— 概率本身没有坏，坏的是分辨力。
+> - **值不值得并进任何决策：不值得。** 14/20 **全靠那 5 条短 passage**：浏览器项只有 **9/14 = 0.64**
+>   （GGUF 4B 是 12/15 = 0.80），而控制器最先要用的两类恰是最差（`goal_done` 0/1 假成功、
+>   `click_target` 1/2 且另一个不可答）。它确实做对的类型：`blocker` 2/2（含 fixture state）、
+>   `type_target` 2/3、`progress` 1/1（靠取整）、短 passage `answer` 5/5、外加 1 个 `action`
+>   —— 即"短 state、少选项、非 `goal_done`"的辅助判断。与 `docs/local-kev-bringup.md` 由熵/pick
+>   测试得出的"只适合短 state 辅助判断"结论一致，现在有了可比的 20 题数字。
+> - **该 422 可解除，但解除后仍然错**：把 `kev/model.py` 的行上限做成 env 可配（**本机 clone 的本地评估
+>   补丁**，默认值与发布一致；diff 见 `experiments/kev-4b/README.md`）后，两条 422 都消失（20/20 可答，
+>   packed fixture step 4,543 ms / 12,073 input tokens，19 条原有答案逐位不变），**但准确率不变（仍
+>   14/20）**：新答出的那题给 `e17 @ 0.1375`（期望 e1 排第 4 位 @ 0.0724；hosted Jev 与 GGUF 4B 都选的
+>   e15 只有 0.0370），top1−top2 = **0.0059** —— 仍是掷硬币，top1−top2 ≤ 0.05 计数从 3/11 升到 4/12。
+>   结构性修复买不到分辨力。
+>
+> **‡ Kev 4B 两行** —— 同一个 runner、同一 20 条 + 同一真实 fixture 一步，`--run jaredpalmer/kev-4b`
+> 经 preflight 逐字核对（服务卡 `run`/`base=Qwen/Qwen3.5-4B-Base`/`temperature=2.1435` 全部核对过）。
+> **注意这不是"未训练基座"候选**：Kev 4B 是同家族上训练过的 pointer-head checkpoint，跑在它自己的
+> MLX 服务里（`HF_HUB_OFFLINE=1`，无需网络）—— 与上面四行"未训练 GGUF"不同类，但它可以在这 20 条上
+> 直接对拍，所以并列在表里。
+> - **它现在是本地最好的一档**：16384 下 **19/20 = 0.95**，比 GGUF 候选 1（16/20 = 0.80）**高 3 题**，
+>   且与 hosted Jev 天花板 **同分（都 19/20），三个切片逐个持平**（browser 14/15、noul 5/5、
+>   action+click 5/5）。16384 与 8192 两次跑过的 19 条**答案逐位相同**（行上限不动模型）。
+> - **它在一个题型上真的赢过 hosted Jev**：`click_target` **2/2 vs 1/2** —— 两者唯一的分歧是
+>   `ddg-click-target-aapl`，Kev 4B 给 **e1 @ 0.2142**（= 仓库手写标签，五个模型里唯一命中者；
+>   hosted Jev 与 GGUF 4B 都给 e15）。反过来它在 `submit_after_type` **1/2 vs 2/2** 输给 hosted Jev
+>   （`github-login-submit` 给 0.6194 → true，应为 false）。总分持平，各错一题，错在不同的题。
+> - **控制器最关键的那一问被修好了**：真实 fixture state 上 `goal_done` = **0.0607**（判"未完成"，正确）
+>   —— Kev 0.8B 在同 state 上是 **0.6952（假成功）**，GGUF 4B 是 0.006。浏览器 noul 的分离度从
+>   0.8B 的 **−0.1196** 翻到 **+0.6107**。退化签名消失：`near-uniform` **0**、top1−top2 ≤ 0.05 **0**
+>   （0.8B 分别是 1 与 4），8 条 noul 无一条贴中线，12 条 choice/score 的 Σp 全部按常规合 1
+>   （min 0.9999，0 违例）。
+> - **代价 = 上限与内存**：19/20 需要那个本地评估补丁（发布上限 8192 下是 18/20 = 0.90，且决定性的
+>   click_target 题**答不了**）；延迟均值 2.2 s / 单题最大 **12.2 s**（55 选项那题），packed fixture 一步
+>   **23.8 s / 12,073 tokens**，无一条超过 60 s。**内存是这行的真正限制**：冷启动 footprint 18–19 GB
+>   （与 8192 相同，全是 `IOAccelerator` 的 GPU 内存），跑完一轮 16384 后涨到 **36 GB**，把系统
+>   swap 从 16.7 GB 顶到 **28.3 GB used / 28.7 GB total（仅剩 416 MB）**；停服后回落（free 52–54%）。
+>   48 GB 机器上这已是可运行的边缘，但本轮没有任何一次请求因换页超时或失败。
+
+**★ 排名变动（本窗口）**：表里"未训练 GGUF 候选 1"（Qwen3.5-4B Q4_K_M，16/20 = 0.80）仍是**那个集合**内的
+第一；但**整体最好的本地后端现在是 Kev 4B @16384 = 19/20 = 0.95**（训练过的 pointer-head checkpoint + 自己的
+MLX 服务），比 GGUF 候选 1 高 3 题，并且与 hosted Jev 天花板同分、三个切片逐个持平 —— 详见表格最后两行与 ‡。
+
+1. **4B 明显强于 0.8B，且首次越过平凡基线**：Qwen3.5-4B Q4_K_M **16/20 = 0.80**
+   （0.8B 10/20 = 0.50；「恒选第一个选项」基线 11/20 = 0.55；hosted Jev 19/20 = 0.95）。
+   → **是，超过 0.5**（比 0.8B 高 6 题，比基线高 5 题）。
+2. **它在真实 fixture 一步上给出与 hosted Jev 相同的元素**：click_target = **e15**（Yahoo Finance 的
+   AAPL 行情页）P=0.498，而不是 0.8B 选的 e4（Search 按钮）。该步 **13,809 ms**（含 11.7k-token prefill；
+   且当时后台仍在下载，见 §5 延迟口径）。
+   **独立复测（peer `local-backend-impl`，无下载负载、`-c 16384`）**：冷 18,298 ms、**热 9,002 ms**
+   （click_target 6,135 ms，其余 4 问 630–815 ms）；选择与我们完全一致（e15@0.498、blocker none 0.873、
+   action click、select_target none、goal_done 0.006）；llama-server RSS **3,362 MiB**。
+   → 干净口径：**4B 一步 ≈ 9 s 热 / 18 s 冷**，其中 2/3 时间花在那道 55 选项题上。
+3. **轮转测试（top candidate）：跟内容，不跟位置** —— 与 0.8B 相反：
+   - wiki（100 选项）：k=0/3/7 三次全部命中正确元素（e8/e5/e1），P≈0.99；
+   - ddg（55 选项）：k=0 命中 e1；k=3/k=7 改选 **e11/e7** —— 两处都是**同一个内容**
+     （Yahoo Finance AAPL 行情页），即模型仍按内容选，只是它更偏好 Yahoo 而不是手写标签的
+     investing.com（hosted Jev 同样选 Yahoo）。判分口径见 §4 备注。
+4. **`-c 8192` 跑不动这套 20 题**（第一题就 11,748 tokens，llama-server 400
+   `exceed_context_size_error`）；`-c 16384` 全绿且 `truncated = 0`。launcher 默认 16,384 正确。
+5. **候选 2/3 本轮已测完（链路恢复后补测）—— 排名不变，候选 1 仍是首选：**
+   - **候选 2 Qwen3-4B-Instruct-2507 = 15/20 = 0.75**（差候选 1 一题）。亮点是 noul 满分 **5/5**：
+     `bq-penguins` **0.0000（候选 1 在这里错，P=0.6178）**、`bq-python` 0.0000、`bq-paris` 1.0000、
+     `bq-everest` 1.0000、`bq-trap-failed` 0.0000 —— 决定极锐（标签质量 mean 0.9998 / min 0.9965，
+     全部质量都落在标签上）。也命中 `wiki-login-click-target = e9`（P=1.0000）。轮转 wiki 3/3 正确
+     （e8/e5/e1，跟内容）。
+     **但真实 fixture 一步失手**：click_target 给 **e4 = Search（P=1.000）** —— 与 0.8B 同错，
+     与 hosted Jev/候选 1 的 e15 不同；这一步 11,578 ms，action 给 `stop`（应 click），
+     blocker none / select_target none / goal_done ~0 三项正确。
+   - **候选 3 gemma-3-4b-it = 10/20 = 0.50** —— 与 0.8B 同分、**低于平凡基线 0.55**；
+     noul 3/5（错 `bq-penguins` 0.9715、`bq-python` 0.9935），action+click 1/5。
+     **轮转 6 次只中 1 次**：wiki k=0/3/7 三次都答 `e1`（只有 k=7 恰好正确）+ ddg 三次全错
+     → **读出跟位置、不跟内容**，与 0.8B 同类缺陷（两个 Qwen 4B 都是跟内容的）。
+     fixture 一步 6,495 ms，click_target **e15 @ 0.886（与 hosted Jev/候选 1 同选）**，
+     但 action `select`、blocker `consent_or_permission_dialog`、select_target `e5` 三项错。
+     标签质量 mean 0.7743 / **min 0.0081**（有一行标签质量接近塌掉）。
+   - **可驱动性（上一窗口未验证的 caveat）已关闭**：两个候选的 llama-server 上
+     `/apply-template` 都返回正确模板渲染（候选 2 `<|im_start|>user…<|im_end|>`，
+     候选 3 `<start_of_turn>user…<end_of_turn|>`），且 20 题 + 真实一步全程 0 个 422
+     （无 `LOW_LABEL_MASS`）。

+### 2.1 候选 1 逐题（20 条）
+
+见 `analysis-qwen35-4b.json` / `eval-qwen35-4b.json`（含轮转）。要点：
+
+- 命中（16）：ddg action/blocker/goal_done/typed-submit/type_target、**wiki-login-click-target = e9（唯一
+  「Log in」链接，mass 0.9965）**、wiki type_target、github type_target/value/submit/blocker、
+  wiki progress（score 2.035，p=[0.03,0.02,0.84,0.11]）、5 条 passage 中的 4 条（paris/python/everest/trap）；
+- 未命中（4）：`ddg-click-target-aapl`（选 e15，标签争议见下）、`ddg-typed-action`（click 而应为 type）、
+  `github-login-action`（wait 而应为 type）、`bq-penguins`（true 而应为 false，P=0.6178）；
+- `noul` 不再是常量：`bq-python` 0.3427（false）、`bq-everest` 0.9602（true）、
+  `bq-trap-failed` 0.4416（false ✓）、`goal_done` 0.006（false ✓）、`bq-penguins` 0.6178（MISS）。
+- **置信度这次是可用的弃权信号**（与 0.8B 相反）：12 个 choice/score 答案 mean conf 0.516，
+  错答 mean 0.233（最自信的错答只有 0.598）→ 阈值化后：
+  `conf ≥ 0.5` 覆盖 8/12、其中 7/8 正确（0.88）；`conf ≥ 0.7` 覆盖 4/12、4/4 正确（1.00）。
+  （对照 0.8B：错答均值 0.700 vs 全量 0.766，几乎无法区分。）
+- 100 选项题的尾部标签有 32 个落出 top-512（1/20 行受影响），其余行标签质量 ≥0.7958。
+
+### 2.2 候选 2 逐题（20 条）
+
+见 `analysis-qwen3-4b-instruct-2507.json` / `eval-qwen3-4b-instruct-2507.json`（含轮转）。要点：
+
+- 命中（15）：`ddg-goal-done-aapl`、`ddg-typed-type-target`、**`wiki-login-click-target` = e9（P=1.0000）**、
+  `wiki-typed-type-target`、`github-login-type-target`/`type-value`/`submit`、`github-login-blocker`、
+  `wiki-progress`（score 2.0000）、**noul 5/5**（paris 1.0000 / everest 1.0000 / trap 0.0000 /
+  **penguins 0.0000** / **python 0.0000**）；
+- 未命中（5）：`ddg-click-target-aapl`（**e4 @ P=1.000** —— 与 0.8B 同错，e4 是 Search 按钮）、
+  `ddg-action-aapl`（stop）、`ddg-typed-action`（wait）、`ddg-typed-submit`（P=0.097）、
+  `github-login-action`（wait）；
+- **决定极锐**：标签质量 mean 0.9998 / min 0.9965，noul 的答案全是 1.0000/0.0000 —— 与候选 1 的分散分布相反；
+- 轮转：wiki 3/3 正确（e8/e5/e1，跟内容）；ddg k=0 正确（e1）、k=3/7 选 e11/e7
+  （两处同为 Yahoo 系内容，与候选 1 相同的内容偏好）。
+
+### 2.3 候选 3 逐题（20 条）
+
+见 `analysis-gemma-3-4b-it.json` / `eval-gemma-3-4b-it.json`（含轮转）。要点：
+
+- 命中（10）：`ddg-goal-done-aapl`、`ddg-typed-type-target`、`wiki-typed-type-target`、
+  `github-login-{action,blocker,submit}`、`wiki-progress`、noul 3/5（paris/everest/trap）；
+- 未命中（10）：`ddg-click-target-aapl`（e15 @ 0.029）、`ddg-action-aapl`（select）、
+  `ddg-blocker-aapl`（consent_or_permission_dialog）、`ddg-typed-action`（select）、`ddg-typed-submit`、
+  `wiki-login-click-target`（e1）、`github-login-type-target`（e5）、`github-login-type-value`（password）、
+  `bq-penguins`（0.9715）、`bq-python`（0.9935）；
+- **轮转 6 次只中 1 次**：wiki k=0/3/7 三次都答 `e1`（只有 k=7 恰好正确），ddg 三次全错
+  → **读位置不读内容**（与 0.8B 同类，两个 Qwen 4B 都是读内容的）；
+- 标签质量 mean 0.7743 / **min 0.0081**：有一行质量近乎塌掉（对照候选 2 的 min 0.9965）。
+
+## 3. 裁定（本次窗口）
+
+- **排名（三个 4B 全部测完）**：**候选 1 Qwen3.5-4B Q4_K_M 第一，16/20 = 0.80**；
+  候选 2 Qwen3-4B-Instruct-2507 **15/20 = 0.75**；候选 3 gemma-3-4b-it **10/20 = 0.50**
+  （与 0.8B 同分、低于平凡基线 11/20 = 0.55）；hosted Jev 天花板 19/20 = 0.95。
+  → **没有候选超过 0.80，首选不变**，registry `default` 无需改动。
+  > **限定（后续窗口）**：这句只对**未训练 GGUF 候选集合**成立。**Kev 4B**（训练过的 checkpoint，
+  > 自己的 MLX 服务）已越过它：**19/20 = 0.95**，与 hosted Jev 同分、三切片持平，并在 `click_target`
+  > 上以 2/2 赢过 hosted Jev（1/2）—— 见 §0 表格最后两行与 ‡。registry `default` 仍指 GGUF 那条
+  > 独立服务路径，两者并存不冲突。
+- **是否超过 0.5？候选 1（0.80）与候选 2（0.75）是，候选 3（0.50）不是。**
+- **候选 2 差一题，但差在最要命的那一步**：准确率只差 1 题，且 noul 满分（唯一压住 `bq-penguins`
+  的模型），但在真实 fixture 一步上 click_target 给 **e4 = Search（P=1.000）**，与 0.8B 同错 ——
+  高分没有换来可用的浏览器动作；候选 1 在这一步与 hosted Jev 同选 e15。
+- **候选 3 不合格**：与 0.8B 同分、轮转 1/6（跟位置不跟内容）、标签质量 min 0.0081。
+- **可驱动性 caveat 已关闭**：候选 2/3 的 `/apply-template` 均返回正确模板渲染，
+  20 题 + 真实一步全程 0 个 422 —— 上一窗口「未验证」的说法不再成立（见 §0.5）。
+- **候选 4/5（Phi-4-mini-instruct、Llama-3.2-3B / SmolLM3-3B）：本轮 1.5 h 预算内未开始。**
+- **落地不变**：registry `default` 仍是 `qwen3.5-4b-q4-k-m`（peer `local-backend-impl` 已端到端验证
+  launcher + `/health` + fixture judge）；0.8B 保留为「更快但更弱」档。
+
+本轮未做的可选补测（**需要单独预算**，不是本轮遗漏）：
+
+```bash
+# 候选 2 与候选 1 只差 1 题（≤3 点）→ 早先 brief 约定补 Q5_K_M/Q8_0 对拍；每个量化 ~2.5-3 GB。
+/opt/homebrew/bin/llama-server -m ~/.jev-browser/models/<file> --port 8100 -c 16384 \

+node /tmp/jev-ceiling/make-table.mjs qwen35-4b qwen3-4b-instruct-2507 gemma-3-4b-it qwen35-08b-c16384
+```
+
+（上表两行新数据由 `make-table.mjs` 机械复算过，与手写行逐格一致；`eval/**` 代码一行未改。）
+
+## 4. 备注与判分口径
+
+- **`ddg-click-target-aapl` 标签有争议**：仓库手写标签期望 `e1`（investing.com 结果，
+  捕获时 `in_viewport=false`），而 hosted Jev、候选 1 与候选 3 都选 `e15`（Yahoo Finance AAPL 行情页，
+  `in_viewport=true`）。两者都算「AAPL 行情」来源 → 该题严格计分让这些模型被低估 ≤1 题。
+  **但这不救候选 2**：它给的是 `e4`（Search 按钮，P=1.000，对 e1 的 P=0.0001），不是 e15。
+- **延迟口径（三个候选的测温条件不同，读表要看这一条）**：
+  候选 1 与候选 3 是**后台正在下载**时测的 → 偏悲观（候选 1 均值 3,072 / 最大 13,895 / fixture 13,809 ms；
+  候选 3 均值 2,189 / 最大 9,725 / fixture 6,495 ms）；**候选 2 是在所有下载结束后测的干净口径**
+  （均值 2,514 / 最大 15,386 / fixture 11,578 ms）。所以候选 2 的均值低于候选 1 并不代表它更快 ——
+  同条件下候选 1 的独立复测是冷 18,298 / 热 9,002 ms（见 §0.2）。下载现已全部结束，
+  候选 1/3 若要对齐条件可复测（本轮 1.5 h 预算内未做）。
+- 标签质量：候选 1 mean 0.9407 / min 0.7958，候选 2 **0.9998 / 0.9965**，候选 3 0.7743 / **0.0081**。
+  候选 1 的分散分布不是缺陷（不是位置先验那种一点集中）；候选 2 的极锐分布伴随「noul 全对」是强信号，
+  但它的 fixture click_target 也以 P=1.000 选错，说明**高 mass 不等于高正确率**。
+- **非单 token 标签：三个候选均为 0**（`multi_token_labels` 全空），字母表校验按预期工作。

+
+### 5.1 本轮（09-24 01:00–02:15）复测
+

+| 01:04–01:09 | node fetch vs curl（同链路、同 URL、同一时刻） | node/undici 稳定 **0.35 MB/s**，curl **0.72–0.93 MB/s** → 下载引擎改用 curl；`--noproxy '*'` 仍解析到同一个 fake-IP `198.18.7.191`，说明代理对两条路径都透明，**没有「绕过代理」的旁路** |
+| 01:09–01:48 | 候选 3 下载（curl 引擎，39 min） | 201,995,056 B 断点续传，**0.933 MB/s** 补完 2.19 GB |

+| 01:04–02:11 | 0.3 MB/s 中止规则 | **一次都没触发**（10 分钟滚动窗口始终高于下限）；全程无 stall、无重连、无重试 |
+
+### 5.2 落盘校验（进 llama-server 之前的硬门）
+
+| 文件 | 字节（= 上游） | sha256（= HF LFS 元数据） |
+|---|---|---|
+| `gemma-3-4b-it-Q4_K_M.gguf` | 2,489,894,016 ✅ | `04a43a22e8d2003deda5acc262f68ec1005fa76c735a9962a8c77042a74a7d19` ✅ |
+| `Qwen3-4B-Instruct-2507-Q4_K_M.gguf` | 2,497,281,120 ✅ | `3605803b982cb64aead44f6c1b2ae36e3acdb41d8e46c8a94c6533bc4c67e597` ✅ |
+
+两个 digest 都算了**两遍**（下载器在安装前算一遍、`shasum -a 256` 在落盘后独立再算一遍），
+都等于上游 LFS sha256；`llama-server /props` 另报 `Q4_K - Medium`、`-c 16384`、chat template 在位。
+→ **本轮没有任何截断/错位的 GGUF 到达 llama-server**（这正是上一窗口浪费掉的那个失效模式）。

+# Kev on the 20-item benchmark (Kev control row)
+
+EXPERIMENTAL — not part of the jev-browser skill.
+
+Grades a **Kev** server (`jaredpalmer/kev` → `/v1/systemone`) on the *same* 20 construction-graded
+items and the *same* real captured fixture step the local GGUF candidates were measured on, so a
+Kev checkpoint can be compared apples-to-apples with them.
+
+- Items: reused verbatim from `../gguf-provider/eval/items.mjs` (read-only import — nothing under
+  `eval/` is touched). 15 browser + 5 passage yes/no, ground truth known by construction.
+- Fixture step: `../gguf-provider/fixtures/judge-state.json` + `judge-questions.json`
+  (5 questions; the state is byte-identical to the ddg item fixture).
+- Request path: the skill's own client, `skills/jev-browser/lib/typesafe.mjs` (`TypeSafeClient`),
+  i.e. exactly the path hosted Jev used — base URL pointed at Kev, answers consumed natively.
+
+## Environment
+
+| | |
+|---|---|
+| Kev checkout | `~/.local/share/jev-browser/kev` (outside this repo, per `docs/local-kev-bringup.md`) |
+| venv python | `~/.local/share/jev-browser/kev/.venv/bin/python` (do **not** use `uv run`; ~49 s overhead) |
+| checkpoint list | `GET http://127.0.0.1:8008/v1/models` — check `run`, `base`, `backend`, `temperature` |
+| port | **8008** (0.8B control) or **8012** (a second checkpoint / the 0.6B entry) |
+| auth | `KEV_API_KEY` unset on the server ⇒ open; the client always sends `Authorization: Bearer <key>`, so `TYPESAFE_API_KEY=local` is the placeholder |
+| cost | `$0` (loopback base URL ⇒ `pricePerMtokFor` returns 0) |
+
+`serve.py` has **no `--host`** (host is always `127.0.0.1`) and **silently falls back to `runs/smoke`**
+when a run id is not resolvable — see traps 1 and 7 in `docs/local-kev-bringup.md`.
+
+## Launcher — `skills/jev-browser/bin/jev-kev.mjs`
+
+The one-command path, and the one to prefer over the manual steps below. It fetches and verifies the
+checkpoint plus its base, starts the server, and prints the skill's env line last (everything else
+goes to stderr, so the line can be eval'd).
+
+```bash
+node skills/jev-browser/bin/jev-kev.mjs                       # published 8192 cap
+node skills/jev-browser/bin/jev-kev.mjs --row-limit 16384      # needs --patch-row-limit first
+node skills/jev-browser/bin/jev-kev.mjs --verify-only          # re-hash 29 files, download nothing
+node skills/jev-browser/bin/jev-kev.mjs --list-files           # the pinned manifest
+node skills/jev-browser/bin/jev-kev.mjs --patch-row-limit      # optional; prints diff + revert
+node skills/jev-browser/bin/jev-kev.mjs --unpatch-row-limit
+```
+
+How it behaves (all exercised in the run log below):
+
+- **Pinned manifest, verified per file.** The 29 files of `jaredpalmer/kev-4b@485ace87` (16) and
+  `Qwen/Qwen3.5-4B-Base@1001bb4d` (13) are embedded in the launcher with size + sha256 (LFS blobs) or
+  git-blob sha1 (small files), generated by `make-manifest.mjs` from the Hub tree metadata. Every file
+  on disk is re-hashed before it is trusted; a file that fails is deleted and the next source is tried,
+  and if every source fails the launcher exits **3** rather than caching the bytes.
+- **Sources, fastest first:** `modelscope → hf → hf-mirror`, overridable with `--source`/`--sources`.
+  A source that serves bytes failing verification is demoted for the rest of the run — which is how
+  ModelScope's different `.gitattributes` is caught, since the base's small files must come from HF.
+  Each file logs which source it came from and its MB/s; a stall (no bytes for 120 s) moves to the
+  next source.
+- **Resume:** partials live at `blobs/<hash>.incomplete` and are resumed with `Range`; a verified file
+  is never re-downloaded.
+- **Cache layout:** `blobs/`, `refs/main`, `trees/<commit>.json`, `snapshots/<commit>/<name>` symlinks —
+  what `resolve_run` → `snapshot_download` needs, so the server runs with `HF_HUB_OFFLINE=1`.
+- **Fails loudly, never silently:** a missing checkout or venv prints the exact `git clone` /
+  `uv sync --extra serve` command and exits 2 (before the 9.5 GB verification, not after); a run other
+  than the pinned one exits 2; a server already on the port is reused when it serves the same
+  checkpoint and reported as a conflict otherwise; `--row-limit` without the patch exits 2.
+- **The patch is explicit.** `--patch-row-limit` prints the unified diff and the revert command and
+  leaves the defaults at 8192. On a clone where `kev/model.py` is not the released line, it refuses.
+
+Log of the verification run (M3 Max, 2026-09-24):
+
+```

+
+With `--row-limit 16384` the launcher-started server reproduces the patched row exactly: 19/20 = 0.95,
+browser 14/15, noul 5/5, action+click 5/5, packed fixture step 27,738 ms with `click_target=e1`,
+`goal_done=0.0607` — and all 20 items bit-identical to the recorded `kev-4b-ctx16384` run.
+
+## Commands
+
+**Kev 0.8B — the control row** (what produced `results/`):
+
+```bash
+cd ~/.local/share/jev-browser/kev
+~/.local/share/jev-browser/kev/.venv/bin/python -m kev.serve --run jaredpalmer/kev-0.8b --port 8008
+
+# in another shell, from this repo
+TYPESAFE_API_KEY=local node experiments/kev-4b/run.mjs --run jaredpalmer/kev-0.8b --label kev-0.8b
+
+# then stop it (never leave a server behind)
+hub stop name=kev-8008      # or: kill $(lsof -tnP -iTCP:8008 -sTCP:LISTEN)
+```
+
+**Kev 4B — the same 20 items, once its weights exist.** The *only* changes are the checkpoint on the
+serve line and `--run` on the runner; everything else is identical:
+
+```bash
+cd ~/.local/share/jev-browser/kev
+~/.local/share/jev-browser/kev/.venv/bin/python -m kev.serve --run jaredpalmer/kev-4b --port 8008
+
+TYPESAFE_API_KEY=local node experiments/kev-4b/run.mjs --run jaredpalmer/kev-4b      # label defaults to kev-4b
+```
+
+**Prerequisites for the 4B row** (checked on disk, 2026-09-24): the pointer head and LoRA are already
+fetched — snapshot `485ace87…`, `adapter_model.safetensors` sha256 `9797de69…df2b` (128 MB, r=16,
+alpha=32), plus `head.pt`, tokenizer and `provenance.json`. The one missing piece is the **base** the
+checkpoint itself declares (`provenance.json → config.base`): `Qwen/Qwen3.5-4B-Base`
+(rev `1001bb4d…`, 9.34 GB) — not in the HF cache yet, and `kev.serve --run jaredpalmer/kev-4b` fails
+at load without it. Once it is cached, serving needs no network. Expected card, from the
+checkpoint's own `head.pt`: base `Qwen/Qwen3.5-4B-Base`, `lora=16`, `head.pt["temperature"]`
+`2.1435` (0.8B: `2.4061`; AGENTS.md lists 9B 2.30 / 4B 2.14 / 0.8B 2.41). Both read off the
+checkpoints with `torch.load`, and that is the field that is served: `Checkpoint.load` assigns it
+(`kev/checkpoint.py:172 m.head.temperature = meta.temperature`) and `/v1/models` reports it
+(`kev/serve.py:155`). **Not a conflict:** `result.json` carries `2.3784`, which is the *pre-delta*
+trial's temperature — the delta run refit it and `head.pt` holds the refit, so the 4B card will read
+`2.1435`. The runner prints the served field at preflight, so the row is self-documenting.
+
+**It cannot silently score something else.** `--run` is not decoration: before any request is
+scored, the runner reads `GET /v1/models` and refuses to run (exit 2) unless the *served* checkpoint
+equals `--run`. Two verified failure paths:
+
+```
+$ node experiments/kev-4b/run.mjs --run jaredpalmer/kev-4b          # 0.8B on the port
+✖ served checkpoint is "jaredpalmer/kev-0.8b", but --run asked for "jaredpalmer/kev-4b".
+  …serve the requested checkpoint first:  … -m kev.serve --run jaredpalmer/kev-4b --port 8008
+EXIT=2
+
+$ node experiments/kev-4b/run.mjs --base-url http://127.0.0.1:8012  # nothing listening
+✖ Kev server not reachable at http://127.0.0.1:8012 (fetch failed). …
+EXIT=2
+```
+
+A `kev-4b` checkpoint that is not on disk produces the run-id fallback (`runs/smoke`) **or** a
+download attempt at whatever the WAN gives — either way the preflight stops the run loudly instead of
+scoring the wrong model.
+
+### Options

+--set <all|browser|noul>          --no-fixture          --json
+--only <id[,id]>     run just these items (the fixture step still runs)
+```
+
+## Output
+
+```
+results/
+  raw/<label>/<item>.json      one file per item: request descriptor, untouched server answers,
+                               normalized answer, probabilities, the degeneracy analysis, timing
+  eval-<label>.json            all rows + summary (accuracy slices, Σp, near-uniform, noul separation)
+  fixture-step-<label>.json    the same real captured step (packed, plus a per-question fallback)
+```
+
+Per item the runner records the brief's list: latency (`ms` wall and the server's own `latency_ms`),
+the returned probabilities, whether they sum conventionally (`p_sum`, tolerance 1e-3), and the
+degeneracy signature — `entropy_norm` (normalized Shannon entropy of the answer; ≥ 0.95 = near-uniform),
+`margin`/`coinflip_margin` (top1 − top2 ≤ 0.05 = almost a coin toss), `choice_is_argmax`
+(whether the reported `choice` matches its own probability map), and for `noul` `dev_from_half` /
+`near_half` / `pinned_high`.

+
+```
+branch too long: 4700 tokens with a 6407-token state (row limit 8192)
+```
+
+`kev/model.py:15` — `SERVE_MAX_STATE, SERVE_MAX_BRANCH = 8192, 8192`; the row limit is
+`state + one branch ≤ 8192` and is **not** env-configurable. The GGUF side hit the identical wall
+(11,748 tokens on the same fixture) and fixed it with `llama.cpp -c 16384`; Kev has no equivalent
+knob, so the 55/100-candidate `click_target` questions on a ~6.4k-token real state are
+**unanswerable as served**. The fixture step therefore falls back to one question per pass, which
+still yields the four short-branch questions. See *Row limit* below for the source check, the local
+evaluation patch that makes the limit settable, and what the two refused items answer once it is
+raised (short version: they answer, and the answers are still coin tosses).
+
+### Same failure mode as the entropy tests, on the graded items
+
+- **noul splits by state length, it is not globally pinned.** Short passages: 5/5, extreme
+  (0.0070 / 0.1312 vs 0.9816 / 0.9859). Browser states: inverted and at chance —
+  `goal_done` = **0.6952** on the fixture state (a false success; the GGUF 4B reads **0.006** on the
+  identical state), and both `submit_after_type` items sit at **0.4594 / 0.4627**, i.e. ±0.04 of a
+  coin flip — the one that scores "correct" does so because 0.4627 lands under the 0.5 threshold.
+- **Choice distributions flatten on the long element lists.** `action` 0.4984/0.2385/0.1625 and
+  `blocker` 0.4589/0.2400/0.1767; the 4-level `progress` score is near-uniform (H_norm 0.973,
+  0.30 vs 0.30 for the top two levels) and only scores because the ±0.5 window rounds 1.749 to 2.
+
+### Verdict
+
+Kev 0.8B's 14/20 is **not** a number worth averaging into any shipping decision:
+
+- It beats the GGUF 0.8B (10/20) and the always-first-option baseline (11/20) but is *wholly carried
+  by the 5 short passages* (5/5) — which the GGUF 4B also nearly aces and which no browser decision
+  depends on. Strip the passages and it is **9/14 = 0.64 on browser items vs 12/15 = 0.80 for the
+  GGUF 4B**.
+- The two question types a controller actually needs first (`goal_done`, `click_target`) are its
+  worst: `goal_done` 0/1 (false success at 0.6952), `click_target` 1/2 with the other *unanswerable*.
+- The two items that passed at ~0.46 (`submit_after_type`) would flip on any threshold change.
+
+**Which types it did get right:** `blocker` (2/2, incl. the fixture state), `type_target` (2/3),
+`wiki-progress` (by rounding), the short-passage `answer` nouls (5/5), and one `action` — i.e.
+short-state, few-option, non-`goal_done` judgments. That is the same "short-state auxiliary only"
+verdict `docs/local-kev-bringup.md` reached from entropy/pick tests, now reproduced on the graded
+items.

+- Browser-state noul separation flips from **−0.1196** (0.8B, inverted) to **+0.6107** (4B); overall
+  +0.7018. The degeneracy signature is gone: 0 near-uniform, 0 coin-ties, no noul near 0.5.
+- By question @16384: `click_target` 2/2, `action` 3/3, `blocker` 2/2, `goal_done` 1/1,
+  `type_target` 3/3, `submit_after_type` 1/2, `type_value` 1/1, `progress` 1/1, `answer` 5/5. The
+  **only** miss is `github-login-submit` (P(yes)=0.6194 → true, want false).
+- Against hosted Jev (also 19/20, same three slices): Kev 4B is **better on `click_target` (2/2 vs
+  1/2)** and **worse on `submit_after_type` (1/2 vs 2/2)**; each misses exactly one item, a different
+  one.
+
+### Memory — the real constraint
+
+| | @8192 | @16384 |
+| --- | --- | --- |
+| footprint, fresh idle → after one request | 18 GB → 19 GB | 18 GB → 19 GB |
+| RSS peak during the full 20-item run | 12.2 GiB | 18.6 GiB |
+| footprint after the full run (incl. the 12k-token packed step) | — | **36 GB, entirely `IOAccelerator` (GPU)** |
+| swap | unchanged (16.2 GB used) | driven 16.7 → **28.3 GB used of 28.7 GB total (416 MB free)** |
+
+`ps -o rss=` under-reports this process badly — MLX's buffers are evictable, so RSS fell to 174 MiB
+while idle — hence `footprint -p <pid>` is the number to trust. The raised limit costs nothing at
+rest (18–19 GB either way, identical to the 8192 server); the 36 GB appears under the real workload,
+and on this 48 GB machine that means heavy swap. Nothing failed or stalled (no request timed out) and
+free memory recovered to 52–54% once the server stopped.
+
+### Verdict
+
+Kev 4B @16384 is **the best local backend measured on this set**: 19/20 = 0.95 vs the GGUF 4B's
+16/20 = 0.80 (+3 items), and it **ties hosted Jev** on the total and on every slice. It beats hosted
+Jev on exactly one question type (`click_target` 2/2 vs 1/2 — it picks the hand-labelled `e1`, the
+only one of the five models that does) and loses on `submit_after_type` (1/2 vs 2/2). It does not
+replace the GGUF path: it needs its own MLX runtime, ~36 GB of GPU footprint, the local row-limit
+patch for the decisive item, and ~2.2 s mean / 12.2 s max per item. At the published limit it is
+18/20 = 0.90 and cannot answer the `click_target` item at all.
+
+## Threshold replay — does the loopback `goal_done` bar transfer to Kev?
+
+The skill's loopback bar (`thresholds.goalDone` / `goalDoneFinal` = **0.174**, see
+`skills/jev-browser/references/config.md`) was measured on the **GGUF readout** over the 15 runs of
+`docs/local-backend-run-smoke.md` §9. Kev answers `goal_done` on a different scale, so the same 15
+goals were replayed against Kev 4B with the same method and the same scoring.
+
+```bash
+# Kev 4B already up on :8008 (bin/jev-kev.mjs --row-limit 16384) and the fixture site on :3111
+TYPESAFE_BASE_URL=http://127.0.0.1:8008 TYPESAFE_API_KEY=local \
+  bash experiments/kev-4b/threshold-replay.sh /tmp/kev-threshold
+node experiments/kev-4b/threshold-replay.mjs /tmp/kev-threshold
+```
+
+Method, unchanged from §9: one real `chrome --headless` run per goal with the controller's default
+20 s per-request timeout; the reading is the journal's per-step `goal_done`; **ground truth is the page
+that step saw** — `met` means the page itself already satisfied the goal, and a page that merely offers
+a way to it is `not` (§9.1's rule, which is why a DuckDuckGo results page counts as not-met). The
+labels are in `results/threshold-replay/labels.json` with the rule they follow written alongside; for
+the fixture site they are checkable against `tests/fixtures/server.mjs` (the `/docs` secret only
+appears after the reveal button is clicked, `/consent` is only satisfied once the dialog is gone, the
+cart goal is the POSTed `Cart` page, the signed-in state is `/dashboard`, the contact goal is the
+"Thanks, NAME!" page).
+
+Per run (46 readings, 15 runs; `met` = how many of that run's pages satisfied the goal):
+
+| run | status | steps | met | first reading | max reading | worst not-met | lowest met |
+| --- | --- | --- | --- | --- | --- | --- | --- |
+| R1 | success | 1 | 1 | 0.967 | 0.967 | — | **0.967** |

+| R3 | stuck | 5 | 0 | 0.013 | 0.019 | 0.019 | — |
+| R4 | success | 3 | 1 | 0.028 | 0.683 | 0.145 | **0.683** |

+| R7 | max_steps | 7 | 0 | 0.014 | 0.040 | 0.040 | — |
+| R8 | max_steps | 9 | 0 | 0.011 | 0.034 | 0.034 | — |
+| g1 | success | 1 | 0 | 0.195 | 0.195 | 0.195 | — |
+| g3 | success | 2 | 1 | 0.058 | 0.847 | 0.058 | 0.847 |

+| p4 | success | 4 | 1 | 0.070 | 0.990 | 0.083 | 0.990 |
+
+**Result — the Kev 4B band is (0.341, 0.683], so 0.174 does NOT transfer:**
+
+| threshold | correct success | **false success** | false stuck | correct stuck |
+| --- | --- | --- | --- | --- |
+| 0.10 | 5 | 6 | 0 | 4 |
+| **0.174 (current loopback default)** | 7 | **4** | 0 | 4 |
+| 0.25 (the GGUF winner) | 7 | 2 | 0 | 6 |
+| 0.30 | 7 | 1 | 0 | 7 |
+| **0.35 – 0.68** | **7** | **0** | **0** | **8** |
+| 0.482 (geometric midpoint of the band) | 7 | 0 | 0 | 8 |
+| 0.70 | 6 | 0 | 1 | 8 |
+| 0.85 (the hosted default) | 5 | 0 | 2 | 8 |
+
+- At the current loopback default **0.174 a Kev run calls four not-met pages a success** — R5 (0.341,
+  the consent dialog still up), p3 (0.257, nothing started), g1 (0.195, the product page, not the cart)
+  and g4 (0.188, the form never sent). Every one of them stops the run before the action that would
+  have finished the goal, which is the failure mode §9.1 calls a false success.
+- **Any value in ~0.35–0.68 is clean** (7 correct successes, 0 false successes, 0 false `stuck`,
+  8 correct `stuck`); the geometric midpoint of the GGUF rule gives **0.482**. 0.7 already loses R4
+  (0.683) and 0.85 also loses g3 (0.847).
+- Kev's `goal_done` has the same shape as the readout's on this set, at a higher level and slightly
+  narrower: **(0.341, 0.683]** (ratio 2.00×) against the readout's (0.111, 0.273] (ratio 2.46×) — which
+  is exactly why the readout's bar is wrong for it in the dangerous direction.
+- Coverage: all 15 goals ran. R1, R2 and R7 failed their first attempt on infrastructure, not on the
+  model (R1/R2: `Chrome did not expose the DevTools endpoint in time`; R7: a driver crash,
+  `Cannot read properties of null (reading 'scrollTop')` in `jevEnumerate`) and are reported from the
+  clean re-run; nothing was dropped. The three DuckDuckGo/Wikipedia runs never reached their goals
+  (5 of 15 runs are live-site runs; the met side comes from the fixture site, example.com and the
+  dashboard).
+- Caveats before reusing 0.482: one machine, one checkpoint, 15 runs, and the fixture site is far
+  tamer than a real page. The skill now resolves this automatically (`thresholds.profile`, `auto` by
+  default): a loopback endpoint is classified from one `GET /v1/models` at run start, a Kev card gets
+  0.482, a name-only readout card gets 0.174, an unclassifiable one gets the highest bar and says so.
+  See `skills/jev-browser/references/config.md`; the resolution is recorded in the run journal's
+  `run.json` before the first step.
+
+Raw evidence in this repo: `results/threshold-replay/{runs.tsv,labels.json,score.txt,journal/*}`.

+## Row limit: `SERVE_MAX_*` — source check, local patch, re-run
+
+### 1. No env var, flag or config raises it (read from source, not the error message)
+
+Clone at `557598f`. `kev/model.py:13-19` — the limits are plain module literals:
+
+```python
+MAX_STATE, MAX_BRANCH, MAX_PACKED = 384, 1024, 2048

+SERVE_MAX_STATE, SERVE_MAX_BRANCH = 8192, 8192
+SERVE_MAX_PACKED = SERVE_MAX_STATE + SERVE_MAX_BRANCH

+| `grep -rn "os.environ\|getenv" kev/*.py` | 11 matches in 7 files. In `serve.py` exactly four: `KEV_PREFIX_CACHE`, `KEV_PREFIX_MIN_TOKENS`, `KEV_DATE_FACTS`, `KEV_API_KEY` — none touches the context. In `model.py` exactly one, for a different purpose: `KEV_SHAPE_BUCKET`. |
+| `serve.py` CLI | `main()` defines only `--run`, `--fallback`, `--port`. No `--ctx` / `--max-state` / `--max-branch`. |
+| `LoadOptions.from_env()` (`checkpoint.py:108`) | reads `KEV_BACKEND`, `KEV_DTYPE`, `KEV_MERGE`, `KEV_ATTN`, `KEV_LORA_SCALE`, `KEV_TEMPERATURE` — model/device/precision only. |
+| the consumer | `serve.py:22 from .model import SERVE_MAX_BRANCH, SERVE_MAX_STATE` then `serve.py:54 enc = self.model.encode(..., max_state=SERVE_MAX_STATE, max_branch=SERVE_MAX_BRANCH)` — bound at import, so nothing between the CLI and `encode` can override it. |
+
+### 2. The patch — 2 effective lines, env-settable, defaults unchanged
+
+**LOCAL EVALUATION PATCH ON A THIRD-PARTY CLONE — not upstream, not proposed upstream.** Only
+`kev/model.py` is touched (`git -C ~/.local/share/jev-browser/kev status --porcelain` → ` M kev/model.py`).
+
+`kev/model.py` sha256 pre `2260e2f…26d5d` → post `de08fa5…be13`.

+
+Both refusals clear — `unanswerable: []`, and the packed fixture step runs (12,073 input tokens, was
+422 at 8,192):
+
+| | at 8192 (default) | at 16384 |
+| --- | --- | --- |
+| answered / 20 | 19 | **20** |
+| accuracy | 14/20 = 0.70 | 14/20 = 0.70 (unchanged) |
+| `ddg-click-target-aapl` | HTTP 422 (row limit) | **e17 @ 0.1375** (expected `e1`) |
+| packed fixture step | HTTP 422 (row limit) | **4,543 ms** — goal_done 0.6950, action click, blocker none, select_target none, click_target e17 |
+| the 19 previously answered items | — | **19/19 bit-identical** probabilities and predictions |
+| 20-item latency ms | mean 590 / median 56 / max 6,353 | mean 494 / median 76 / max **3,135** |
+| peak server RSS | — | idle after load **3.60 GiB** → **peak 3.61 GiB** during the run (min 1.71 GiB between requests) |
+
+The newly answerable 55-option item costs 3,135 ms wall / 3,114.5 ms server — every other item is
+33–1,626 ms — and the packed 5-question step 4,543 ms wall / 4,520.9 ms server. Memory is flat: the
+6,407-token state and 4,700-token branch are computed and released, so the larger context adds no
+measurable resident cost (measured by sampling the server process RSS every 100 ms).
+
+### 4. The answers at the raised limit are still garbage — resolution is what remains
+
+`ddg-click-target-aapl`, now answerable, 55 options, top-8 probabilities:
+
+```
+e17 0.1375   e18 0.1316   e16 0.1100   e1 0.0724   e26 0.0717   e25 0.0644   e24 0.0593   e15 0.0370
+```
+
+- it picks `e17` at **13.75%**, margin over `e18` **0.0059** — a coin toss over the middle of the list;
+- the expected label `e1` ranks 4th (7.24%), and `e15` — the element hosted Jev (0.75) and the GGUF 4B
+  (0.498) both pick — gets **3.70%**;
+- the packed step's `click_target` is the same near-tie (`e17` 0.1375, margin 0.0059), and its
+  `goal_done` is 0.6950, a false success (the GGUF 4B reads 0.006 on the same state).
+
+So the patch buys **answerability, not usefulness**: accuracy is unchanged, the item stays wrong, and
+the top1−top2 ≤ 0.05 count goes 3/11 → **4/12** precisely because the newly answered item is another
+near-tie. A structural fix cannot repair a resolution failure — this is the expected shape.
+
+One numeric note: the packed step's `goal_done` is 0.6950 versus 0.6952 asked alone — a 2e-4
+packed-vs-separate difference, both "true".

+## Judging tiers
+
+Every step asks its questions over one contract (`/v1/systemone`), and three judging backends serve
+it. All three are first-class options and the CLI shows them the same way; **hosted Jev is the
+default**, so a run with no config file and no environment behaves exactly as it always has.
+
+```bash
+jev-browser tier list      # the table below, from the CLI
+jev-browser tier status    # what a run would use right now: baseUrl, tier, resolved goal_done bar, endpoint
+jev-browser tier use kev   # one tier's export line and start command (nothing is written unless --persist)
+```
+
+| | **hosted Jev — the default** | **GGUF readout — default local tier** (`jev-local`) | **Kev — accuracy tier** (`jev-kev`) |
+| --- | --- | --- | --- |
+| how it answers | TypeSafe System One over HTTPS | first-token logprob readout on llama.cpp | trained pointer-head checkpoint on its own MLX runtime |
+| needs | a `TYPESAFE_API_KEY` and network access | Homebrew `llama.cpp`; **no Python** | a Python venv + MLX |
+| disk | nothing to download | 2.6 GiB (registry default) | 9.34 GB base + 152 MiB adapter |
+| memory | — | a few GiB | ~18 GB idle, **36 GB GPU footprint** under load at the raised limit — heavy swap on a 48 GB machine |
+| start | nothing — `https://api.typesafe.ai` | `node <skill-dir>/bin/jev-local.mjs` → `127.0.0.1:8092` | `node <skill-dir>/bin/jev-kev.mjs` → `127.0.0.1:8008` |
+| 20 graded items | **0.95** | **0.80** (the 0.8B entry 0.50) | **0.95** patched / **0.90** published |
+| latency | a step costs roughly $0.0002 at a few thousand input tokens | p50 **≈4.3 s per step** (5 questions, one page state) | mean **2.2 s per item**, 12.2 s worst item, **23.8 s** for the packed 5-question step on a 12k-token state |
+| `goal_done` bar | **0.85** / 0.70 | **0.174** | **0.482** |
+| vs hosted Jev (0.95) | — | below it | **ties it**, and beats it on `click_target` (2/2 vs 1/2) |
+| known hole | — | `goal_done`, `action` ordering, lists past ~50 candidates | refuses the 55-option `click_target` questions unless the optional row-limit patch is applied |
+
+Pick the GGUF tier unless the number is the point: it is one command, needs no Python, and 0.80 is
+enough for short states. Pick Kev when you need the accuracy — it is the only local backend that
+matches hosted Jev on this set — and accept a Python venv, a 9.34 GB base and tens of GB of GPU
+memory for it. Pick hosted Jev for everything else: it is the default, it needs no download, and its
+0.95 is the number the other two are measured against.
+
+### Hosted Jev — the default
+
+`https://api.typesafe.ai` with `TYPESAFE_API_KEY` set: nothing to download, nothing to start, and the
+`goal_done` bar at 0.85 per step / 0.70 final. `jev-browser tier use hosted` prints the export line
+for coming back to it when a config file, an environment variable or a flag has pointed `baseUrl`
+somewhere local. A local endpoint never costs anything, so a loopback `baseUrl` is priced at $0.
+
+### GGUF readout — the default local tier (`jev-local`, port 8092)
+
+One command serves the same `/v1/systemone` contract from a local llama.cpp server — no API
+key, no network, no cost. The answer is read out of the model's first generated token (options
+are labelled A, B, C …), so nothing is generated and nothing is parsed:
+
+```bash
+node <skill-dir>/bin/jev-local.mjs
+# downloads the registry default (Qwen3.5-4B Q4_K_M, 2.6 GiB) once, starts llama-server with
+# -c 16384 on :8090, then prints:
+# TYPESAFE_BASE_URL=http://127.0.0.1:8092 TYPESAFE_API_KEY=local
+
+export TYPESAFE_BASE_URL=http://127.0.0.1:8092 TYPESAFE_API_KEY=local
+jev-browser judge --state-file state.json --questions-file questions.json --json   # $0
+```
+
+Which model is served is data, not code: `lib/local-models.json` lists each entry with its GGUF
+filename, download URL, exact byte size and label, and its `"default"` picks the one the launcher
+uses. Switching models is an edit to that JSON — or one flag for a single run:
+
+- `jev-local --list-models` — every entry with id, label, size and the default marker (exit 0).
+- `jev-local --model-name <id>` — serve that registry entry instead of the default.
+- `jev-local --model <path.gguf>` — serve a file you already have; add `--model-url <url>` to download it to that path.
+- `jev-local --ctx <tokens>` — llama.cpp context, default **16384**, because a 100-candidate `click_target` step renders to ~11.7k prompt tokens and an 8192 context cannot serve a real step; `--port` / `--llama-port` move the two servers, `--download-only` only fetches the file.
+
+Default is the 4B (`qwen3.5-4b-q4-k-m`): a 2.6 GiB download, and a step in a real `run` takes
+**p50 ≈4.3 s** on an M3 Max (measured max 18.2 s, against the default 20 s client timeout). The
+"~9 s warm / ~18 s cold" step figures in `experiments/gguf-provider/RESULTS.md` are per-question
+cold measurements: within a step the provider asks its questions in order, so the page state is
+paid once (≈1.2 s) and llama.cpp prefix caching brings every later question down to 0.5–0.7 s.
+`--model-name qwen3.5-0.8b-q8` (774 MiB) is ~3× faster per step and much weaker (~0.50 accuracy,
+see limits below); pick it for short, few-option judgments on a small disk.
+
+Apple Silicon (Metal via Homebrew `llama.cpp`) — $0 and no data leaving the machine. A llama.cpp already
+serving the selected file on the llama port is reused and left running when the launcher exits
+(only a server it started itself is stopped with it); one serving a *different* file is refused
+rather than silently answered from. A second invocation while one is running prints the same line
+and exits 0, and `doctor` reports the active registry id in its `local model` line.
+
+### Kev 4B — the accuracy tier (`jev-kev`, port 8008)
+
+```bash
+node <skill-dir>/bin/jev-kev.mjs
+# verifies the checkpoint and its 9.34 GB base in the HF cache (fetching what is missing, resuming
+# partials, never re-downloading a file whose size and hash already match), starts the server on
+# :8008 and prints:
+# TYPESAFE_BASE_URL=http://127.0.0.1:8008 TYPESAFE_API_KEY=local
+```
+
+It answers from the same `/v1/systemone` contract, so nothing else changes — the same `judge`, the
+same `run`. Extras: `--verify-only` re-hashes the whole cache and downloads nothing, `--download-only`
+fetches without starting anything, `--list-files` prints the pinned manifest (sizes and hashes for
+all 29 files), and `--source`/`--sources` pin the mirror order (ModelScope is fastest where it hosts
+the repo, then huggingface.co, then hf-mirror). A file that fails its published size or hash is
+deleted and the next source is tried; if every source fails, the launcher exits 3 rather than caching
+the bytes. A server already answering on `--port` is reused when it serves the same checkpoint and
+reported as a conflict otherwise.
+
+**The optional row-limit patch is never applied silently.** The released Kev server caps one request
+at `state + one branch ≤ 8192` tokens, so a real page's 55-option `click_target` question is refused
+with HTTP 422: that is published behaviour, and it scores **18/20** on the 20 graded items with the
+packed fixture step refused. `jev-kev --patch-row-limit` makes the cap settable — it prints the diff
+and the revert command, and the defaults stay 8192; `jev-kev --row-limit 16384` then serves at the
+raised cap for that run and scores **19/20**, tying hosted Jev. Without the patch, `--row-limit`
+exits 2 and says so.
+
+Cost: a Python venv plus MLX, a 9.34 GB base, and memory as in the table above. On this 48 GB machine
+the raised cap drove swap from 16.7 GB to 28.3 GB used while a full 20-item pass ran; nothing timed
+out, but that is the ceiling to plan around. Numbers: `experiments/kev-4b/README.md`.
+
+### One contract, three `goal_done` bars
+
+The bar is per backend because the three read the question on scales that do not overlap — that is
+what the `goal_done bar` row in the table above records, and why `tier status` and `doctor` resolve
+it from the endpoint rather than from one fixed number.
+
+A single judge is not the same as a whole `run`. Measured over 15 real local runs (goals, journals
+and per-step numbers: `docs/local-backend-run-smoke.md`) a run **can** finish — a Wikipedia search
+goal reached `status=success` in 4 steps — but the bar for saying so is not the hosted one. Scored
+as a termination rule (the first step whose reading crosses the line, §9), `goal_done >= 0.25` —
+any value in 0.12–0.28 — called **every one of the 7 runs that reached the goal** a success, at a
+page that already showed the goal, and never fired on the 8 runs that never got there: 7 correct
+successes, 0 false successes, 0 false `stuck` (the hosted 0.85 gave 4 / 0 / 3). A loopback
+`baseUrl` therefore got **0.174**, the geometric midpoint of that band; hosted Jev still gets 0.85
+and 0.70. Since a second local tier shipped, that single value is no longer what every loopback
+endpoint receives — the bar is a per-backend profile instead (next paragraph), and 0.174 is the
+`local-readout` profile's value.
+
+**That band is the GGUF readout's, and it does not transfer to Kev** — so the bar is a per-backend
+**profile** (`thresholds.profile`, `auto` by default), not one loopback value. A non-loopback
+`baseUrl` is `hosted` (0.85 / 0.70). A loopback one is classified with one `GET /v1/models` at run
+start: a Kev card names the checkpoint it loaded (`run`, `base`) → `kev` (**0.482** / 0.482); the GGUF
+launcher's card is name-only → `local-readout` (**0.174** / 0.174). If that call fails or the card is
+unrecognised the run uses the **highest** bar (0.482) and records why — a false `stuck` is visible, a
+false success is not. The resolved profile, value and reason are printed by `doctor` (`goal_done bar`)
+and written to the run journal's `run.json` before the first step; pinning `thresholds.profile` (or an
+explicit `thresholds.goalDone`) still wins for an endpoint the table does not fit.
+
+Why Kev needs its own number: replaying the same 15 §9 goals against Kev 4B
+(`experiments/kev-4b/threshold-replay.{sh,mjs}`, same method, same scoring, ground truth read off the
+page each step saw) gives the same shape at a higher level and slightly narrower — **(0.341, 0.683]**
+against the readout's (0.111, 0.273]. At **0.174 a Kev run calls four not-met pages a success** (R5
+0.341, p3 0.257, g1 0.195, g4 0.188), each stopping before the action that would have finished the
+goal; **any value in ~0.35–0.68 is clean** (7 correct successes, 0 false successes, 0 false `stuck`,
+8 correct `stuck`), and 0.85 loses a legitimate success (the fixture `/docs` page with the secret
+revealed, reading 0.683). Full table: `experiments/kev-4b/README.md`.
+
+What is still weak is choosing the action: `action` selection ranked
+`type` last even when `type_target` and `type_value` were both right, and chose `stop` with the
+goal one click away, while `click_target` is the strong half (right element first on a 65-element
+page, 0.71–0.78). `blocker` is unreliable in the same way — it produced a false `needs_user` on a
+plain pricing page. Do not replace `goal_done` with a code-side rule: "the goal's named entity
+appears in the final URL or title" false-fired on 4 runs — 2 of them never completed, because
+search URLs echo the query and product URLs contain the product name — and loop detection
+false-fired on 4 as well; aggregating the last readings never beat the single reading either.
+
+Limits: it is a short-state classifier, not a Jev replacement — no few-shot examples, no
+configurable system prompt, no images. Measured on 20 graded items: the default 4B scores 0.80
+(hosted Jev 0.95, positional baseline 0.55, the 0.8B entry 0.50 — it tracks position more than
+option text, the 4B tracks the text). Accuracy and confidence still fall as option lists grow, so
+prefer hosted Jev for element lists past ~50 candidates — `goal_done` is the exception, which is
+why it carries the local bar above (selection stayed correct on the 64-candidate page, at 0.71–0.78
+instead of ~0.99). When the option labels cannot be read out at all the server answers HTTP 422
+`LOW_LABEL_MASS` naming the question instead of guessing. Measured numbers:
+`experiments/gguf-provider/RESULTS.md` and
+`experiments/gguf-provider/results/local-models-4b.md`.

+
+Usage:
+  jev-kev [--port 8008] [--run ${RUN_ID}] [--clone <dir>]
+  jev-kev --verify-only                 re-hash the whole cache; download nothing
+  jev-kev --download-only               fetch the checkpoint and its base, start nothing
+  jev-kev --list-files                  print the pinned manifest and exit
+  jev-kev --patch-row-limit             apply the optional row-limit patch to the local clone
+  jev-kev --unpatch-row-limit           revert it
+
+What it does, in order:
+  1. fetches ${RUN_ID} (16 files, 152 MiB) and its base ${BASE_ID}
+     (13 files, 9.34 GB) into ~/.cache/huggingface/hub, resuming .incomplete parts and never
+     re-downloading a file whose size and hash already match
+  2. starts the Kev server (${DEFAULT_CLONE.replace(os.homedir(), "~")}/.venv/bin/python -m kev.serve)
+  3. prints, and only then prints:
+       TYPESAFE_BASE_URL=http://127.0.0.1:8008 TYPESAFE_API_KEY=local
+
+Sources (fastest first, falls through on a stall or a verification failure):
+      --source <name>    pin one: modelscope | hf | hf-mirror
+      --sources <a,b,c>  set the whole order
+
+Optional row-limit patch — off by default, and never applied silently:
+  The released server caps a request at state + one branch <= 8192 tokens (kev/model.py), so the
+  55-option click_target questions on a real page are REFUSED with HTTP 422. Published behaviour is
+  18/20 on the 20 graded items with that 422; the patch makes the cap settable and reaches 19/20.
+      --patch-row-limit    one explicit edit to the local clone, prints the diff and the revert command
+      --row-limit <tokens> serve with the cap raised (requires --patch-row-limit; without the patch
+                           the server has no such knob and this exits 2)
+
+Tuning:
+      --port N           port of the Kev server              (default 8008)
+      --run <id>         checkpoint to serve                 (default ${RUN_ID})
+      --clone <dir>      Kev checkout to use                 (default ${DEFAULT_CLONE.replace(os.homedir(), "~")})
+      --timeout <secs>   wait for the server to become ready (default ${READY_MS / 1000})
+  -h, --help             this text
+
+Env (passed through to the server): KEV_TEMPERATURE, KEV_BACKEND, KEV_DTYPE, KEV_PREFIX_CACHE, ...
+  HF_HUB_OFFLINE=1 is set for the server: the launcher has already verified the cache.
+
+Exit codes: 0 ok · 1 runtime failure · 2 usage/config (missing venv, port busy, wrong checkpoint)
+            · 3 a file failed size/hash verification and was removed
+
+A server already answering on --port is reused when it serves the same checkpoint and reported as a
+conflict otherwise; one this launcher started is stopped with it.

+## Termination thresholds on a local backend
+
+The tiers themselves — what each backend is, what it needs, how to start it, its port, its 20-item
+score and the bar it gets — are listed once, in [`SKILL.md`](../SKILL.md#judging-tiers), and
+`jev-browser tier list | status | use` prints the same thing from the CLI. This section is only
+about the thresholds.
+
+`goal_done` is the question that ends a run, but its *value* depends on the backend — and the two
+local backends this skill ships read it on scales that do not overlap. So the value is a **profile**:
+
+| `thresholds.profile` | `goalDone` / `goalDoneFinal` | measured on |
+| --- | --- | --- |
+| `hosted` | 0.85 / 0.70 | the shipped Jev default |
+| `local-readout` (GGUF, `bin/jev-local.mjs`) | 0.174 / 0.174 | `docs/local-backend-run-smoke.md` §9 — band 0.111 – 0.273 |
+| `kev` (`bin/jev-kev.mjs`) | 0.482 / 0.482 | `experiments/kev-4b/README.md` — band 0.341 – 0.683 |
+
+`auto` (the default) picks one: a non-loopback `baseUrl` is `hosted`; a loopback one
+(`127.0.0.1` / `localhost` / `::1`) is classified from **one `GET /v1/models`** at run start, because
+only the endpoint knows which backend it is. A Kev card names the checkpoint it loaded (`run`, `base`)
+→ `kev`; the GGUF launcher's card is name-only → `local-readout`. If that call fails or the card is
+one this build does not recognise, the run uses the **highest** bar (0.482) and says so in the journal:
+a false `stuck` stops the run where you can see it, while a false success is silent.
+
+Each band above is the maximin geometric midpoint of its own measured sides (√(0.111 × 0.273) and
+√(0.341 × 0.683) — 1.57× and 1.41× from each side respectively). Code-side rules are not a
+substitute: "the goal's named entity appears in the final URL or title" false-fired on 4 of the 15
+runs (2 of them never reached the goal) and loop detection false-fired on 4, so the threshold stays
+the rule and only its value moves.
+
+**Pinning it by hand is the fallback, not the instruction.** A value any layer provides still wins —
+`thresholds.profile: "kev"` in a config file (or `config set thresholds.profile kev`), or an explicit
+`config set thresholds.goalDone 0.4` — which is what you want when the profile table does not fit your
+endpoint (a new checkpoint, a fine-tune, a backend this build has never seen). `jev-browser doctor`
+prints the pair a run would use, the profile it came from and why (`goal_done bar`), and the run
+journal's `run.json` carries the same record — profile, reason, applied values and the raw
+classification — written before the first step.
+
+The readout's side, in full: 7 successful and 8 never-successful runs, one machine, one 4B
+quantization, three sites; the lower edge (0.12) is only 1.08× the worst not-met reading observed
+(0.111, inside a run that did succeed). Real sites will spread wider, so re-measure before trusting
+either local bar with a model nobody has scored.
+
+**The Kev band, and why the readout's bar must not be reused for it.** Kev (`bin/jev-kev.mjs`) is a
+trained pointer-head checkpoint, not a first-token logprob readout: on the real fixture page the Kev
+4B says **0.0607** where the GGUF 0.8B said 0.6952 and the GGUF 4B said 0.006. Replaying the same 15
+§9 goals against Kev 4B, scored the same way (first step crossing the line, ground truth from the page
+that step saw; readings, labels and scorer in `experiments/kev-4b/threshold-replay.{sh,mjs}`):
+
+| threshold | correct success | false success | false stuck | correct stuck |
+| --- | --- | --- | --- | --- |
+| **0.174 (the readout's bar)** | 7 | **4** | 0 | 4 |
+| 0.25 | 7 | 2 | 0 | 6 |
+| 0.35 – 0.68 | **7** | **0** | **0** | **8** |
+| 0.482 (this profile) | 7 | 0 | 0 | 8 |
+| 0.85 (the hosted default) | 5 | 0 | 2 | 8 |
+
+At 0.174 four not-met pages read as success (R5 0.341, p3 0.257, g1 0.195, g4 0.188) and each stops
+the run before the action that would have finished the goal. At 0.85 a legitimate Kev success —
+the fixture `/docs` page with the secret revealed, reading 0.683 — is lost as a false `stuck`.
