Subject: [PATCH 1/6] feat(harness): replay complete F257 substrate on latest
 main
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Why: rebuild develop_base from upstream main while preserving the reusable Harness ledger, routing facts, lifecycle tracing, evaluation runtime, and console surfaces without carrying fork-instance configuration or governance overlays.

 # Harness Eval Control Plane
 
 ## Canonical Owner
 
-F192 owns the socio-technical harness evaluation contract: harnesses declare expected behavior, runtime eval observes actual behavior, attribution explains gaps, verdict packets hand off evidence to feature owners, and later eval verifies closure. F266 owns the durable lifecycle control plane after an actionable verdict is published: the immutable bundle seeds identity, an append-only Redis event log records authenticated state transitions, a reconciler resurfaces overdue work, and F248 surfaces project canonical state for humans. Its operational acceptance layer also migrates audited legacy v1 roots into stable in-memory cases without rewriting artifacts, binds repair and cadence work to separate TaskStore + F167 responsibilities, and turns `nextEvalAt` into executable re-evaluation work. F254 extends this control plane with one domain adapter: `freshness-closure-replay` resolves only server-owned fixtures or durable closure identity, normalizes raw/snapshot/attribution/provenance evidence, and generates an `eval:freshness` verdict without moving control-plane ownership out of F192/F266. F278 owns the distinct pre-verdict responsibility object for each canonical cat-authored paw-feel signal: MessageStore remains body truth, F245 remains read-only analysis truth, and one append-only source-ref ledger projects duty into `thread_eval_friction`, Workspace「评估」live view, Settings Eval Hub history and the original message without copying marker prose. All four surfaces read the same F278 event projection; none owns a second disposition writer.

F257 owns the per-unit ledger lifecycle and the exact path from closed `TraceEpisode` through append-only `TraceAnnotation`, immutable `EvaluationSnapshot`, and append-only `MetricResult` to the segment-lifeline projection. An Objective is a static definition plus unit attachments and Metric rules; it has no lifecycle state machine.
 
 ## Use This When
 
 - Adding or changing an Eval Contract for a harness, skill, MCP tool, SOP, or shared rule.
 - Adding or changing a SOP stage definition or predicate-backed hard rule.
 - Adding an eval domain registry entry such as `eval:a2a` or `eval:memory`.
-- Adding or changing F254 freshness replay selectors, fixture truth, durable closure normalization, derived metrics/samples, or live verdict generation.
-- Adding or changing a decision-bearing measurement bundle, opportunity join, uncertainty/insufficient state, or withdrawal condition.
 - Producing or validating Verdict Handoff Packets.
-- Recording owner acknowledgement, action plans, landed fixes, re-evaluation, reasoned operator suppression, or SLA escalation for an actionable verdict.
-- Recording or projecting per-paw-feel `new / seen / route_pending / routed / closed / duplicate / no_action` responsibility.
 - Migrating legacy scheduled tasks into unified eval runtime.
 - Deciding whether a harness should `fix`, `build`, `keep_observe`, or `delete_sunset`.
+- Adding a structured rule, MCP marker, or asynchronous semantic classifier that annotates an exact F257 trace episode.
+- Adding or changing Objective/Metric definitions, unit/clause attachments, trigger rules, or code/LLM/replay evaluators.
+- Extending the segment lifeline read model or its governance operations.

 - Freeze canonical opportunity rows at a closed window boundary, reconcile adapter output per ID, and keep adapter recall separate from downstream aggregation/clustering/ranking exclusions.
 - Issue one measurement certificate per decision bundle, keep context/diagnostic metrics non-decision-bearing, bind every result to a frozen cohort and exact decision-procedure version set, and require an intervention card before fix/build/delete_sunset.
 - Require dry-run evidence before disabling or redirecting legacy scheduled tasks.
-- Reuse `extractPawFeelMarkers`; persist source refs, digest identity and cat-signed disposition only. Keep system-thread notices content-free and let Workspace resolve previews from the canonical source on read.
-- Derive Workspace live and Settings history from the same F278 event log/projection. Their different presentation and retention views must not introduce separate status stores, cache authority or mutation endpoints.
+- Keep raw invocation tracing independent from evaluation. Tracing records what happened from invocation start through terminal closure; it does not choose an Objective, Metric, or verdict.
+- Producers only append the unified `TraceAnnotation` schema. `report_harness_signal` creates a pending marker for the authenticated invocation; terminal resolution binds it to the exact episode. Structured rules append the same shape. Unclassified episodes enter a bounded asynchronous semantic sweep.
+- Keep `EvaluationIndexer` deterministic: validate the annotation coordinates against the registry/manifest, deduplicate by incident key, and project query indexes. It must not perform semantic judgment.
+- Keep `EvaluationScheduler` semantic-free: freeze an immutable snapshot only when the Metric's declared threshold, minimum sample, or cadence is ready. Counterexample counters do not invent a denominator or rate.
+- Run LLM semantic review in the eval-cat worker after the response path. Code, LLM, and replay evaluators consume frozen snapshots and append one idempotent `MetricResult`; only a persisted result advances completion watermarks.
+- F257's objective registry and versioned unit manifest are the canonical static definition layer of this same control plane. Registry discovery, unit/clause attachment, Metric rule, trigger, and evaluator kind must agree or loading fails closed.
+- Treat legacy `SegmentJudgment` and window-attributed violation rates as historical compatibility inputs only. New evaluation and Console read models must not consume them, and invalid derived local data is not migrated. Raw traces, messages, and threads remain intact.
 
 ## Do NOT Unify With
 
 - Do not move canonical trace storage out of F153 into this cell.
+- Do not make tracing responsible for evaluation semantics or run LLM classification on the invocation response path.
 - Do not replace F188 Health Dashboard or F200 memory recall metrics here; consume them as domain inputs.
 - Do not treat Eval Hub as a metrics dashboard. A surfaced item must have verdict, owner ask, and re-eval plan.
 - Do not infer owner or action backlinks from filenames, branches, commit text, or chat. Owner continuity and refs change only through authenticated lifecycle commands.

 - Do not let clustering, embedding, Top-N, degradation or source-preview availability gate per-signal visibility.
 - Do not reuse F266 verdict identity for raw paw-feel signals, and do not present F278 `routed` as “fixed”.

 **Why this makes Build-to-Delete easier, not harder**: The maintainer's concern was that metadata turns deletion into deprecation. The opposite is true — currently, deleting a segment requires finding all code paths (condition, variable setup, render call, push), verifying no side effects, removing the template, updating the manifest display entry, and testing. With hooks: set `enabled: false`, the segment stops firing immediately. The code and template can be deleted at leisure in a cleanup pass, or left dormant with zero runtime cost.

+5. **调度和判断分离**：`EvaluationScheduler` 只按阈值、最小样本或 cadence 冻结不可变 snapshot；code/LLM/replay evaluator 读同一 snapshot，成功后 append-only 写 `MetricResult`。失败可重试，不影响原 invocation。

+四层 harness（MCP 工具 GOTCHA / skill 手册 / 家规 / 记忆 feedback）积累了 130+ 口"锅"——每口都是一次真实事故换来的，但**没有任何一层能回答"这口锅最近 30 天拦住过什么"**。锅只加不减：每 turn 注意力被 130+ 条规则稀释（#1018 实证：PR #962 周期 60+ 次 operator 纠正，根因之一是"规则丰富但不在运行时关键路径上"），而同类偏差照样二犯三犯（#1080 A2A claim 冒名、#1082 消息排序假设失效，均为 2026-07 调查线实锤）。系统对偏差的唯一响应是"再添一口锅"，形成越治理越稀释的死循环。
+
+终态：每口锅是**带生命周期的资产**——登记（origin/assertion）→ 触发可观测 → 周期实证评估 → 修补/升级/淘汰。锅账（ledger）是四层锅的单一真相源；"减"第一次成为有证据支撑的合法操作。
+
+## Current State / 现状基线
+
+2026-07-06 首棒审计实测（全表：`assets/F257/harness-audit-2026-07-06.md`）：
+
+**Inventory（四层合计 130+，实测口径）**：
+- MCP 层：43 处 GOTCHA 分布于 30 tools / 10 文件（`packages/mcp-server/src/tools/`），另有 ~13 条 hard-block 断言（400/403/429）
+- Skill 层：48 个 skill（`cat-cafe-skills/manifest.yaml`），9 个 SKILL.md 含 GOTCHA 段
+- 家规层：10 个 magic words + 20 条带事故编号规则（shared-rules.md 806 行）
+- 记忆层：22 个文件（20 feedback + 1 reference + index）
+- ⚠️ 启动包引用数字（86 工具 / 51 skill / 21 GOTCHA）回查后确认是**四个数字四种口径混排**：86=工具全集、43=GOTCHA 出现次数、31=脏过滤行数、51=目录条目数。根因不是单个数字错，而是 `unqualified-count`：数字进决策文档未带 `how_counted`（命令/口径/时间戳），下游不可复算（见 seed-cases SC-002）。
+
+**30 天触发审计（窗口 2026-06-06→07-06，26 个签名，双路：~/.claude transcripts 540 文件 873MB + 运行时磁盘工件）**：
+
+| 观测层级 | 样本 | 结果 |
+|---------|------|------|
+| O1 结构强制（server fail-closed） | 5 | 3 有 firing 实证：hold_ball 429 × 7-8 session（反复触发=锅在挡没在治）；cross_post 路由拒绝 × 2；publish_verdict 403 × 1（**拦下真实越权**：opus 试图替 gpt52 域发 verdict）。但唯一 durable 痕迹 = transcripts 自由文本 echo；pino 4xx 只在 /tmp 重启即失；tool-usage-archive 无 outcome 维度 |
+| O2 提示文本（GOTCHA/家规/magic words） | 15 | 活着 3 条（KD-27 × 15 session 引用、LL-048 × 4、补锅匠 operator 06-29 真实使用）；零痕迹 5 条（星星罐子/碎片够了/LL-054/LL-071/脚手架-as-scold）；**结构性不可测 8 条**——3 条 MCP 提示型 GOTCHA 无违规信号无分母；5 个抽样 skill 30 天 **0 次 Skill-tool 加载**（手册没被打开，GOTCHA 不可能生效；#860 的 30 天新证，检测器已用其他 skill 190+ 次命中验证有效） |
+| O3 记忆文件 | 4 | **4/4 零回读**；其中 feedback_check_hypothesis_first 06-09 创建后从未被读过——记忆层实际是 write-only |
+
+**四个结构性结论**：
+1. 触发可观测性是**意外不是设计**——无任何结构化 guard-rejection 遥测；F237 `InjectionTraceStore` 已在基线但语义是 prompt injection，F254 `FreshnessAttentionEventLog` 提供了可借鉴的 Redis LIST + closed union 形态但语义/TTL 是 freshness 专用。F257 需要独立 `GuardRejectionEventLog` / `HarnessLedgerEventLog`，不复用既有 union。
+2. **无分母问题**——0 触发无法区分"威慑生效"与"锅已死"（waitSourceRef 400 从未 rendered vs cat_disabled 历史触发过，语义完全不同却同样无声）
+3. **重复触发无归因闭环**——hold_ball 429 反复 fire，无人知道谁/为什么/是否该升级为结构修复
+4. **有效修补的主形态被数据指认**——O2/O3 文本层大面积死寂（skill 0 加载 / 记忆 4/4 零回读 / GOTCHA 无分母）vs O1 结构层拿到全部拦截实锤（429×7-8 session、403 拦真实越权、cross_post fail-closed 后"无路由掉球"零复发）。**补文本不改变行为，升结构才改变**：修补环必须显式建模为 O2→O1 升级通路（见「修补环」节 + KD-10），不能只隐含在 eval verdict 一个词里
+
+## What
+
+> Phase 拆分为对齐稿：opus（架构）/ codex（风险与落地）对齐 + Design Gate 后冻结。
+> **2026-07-07 问题先行修正**（co-creator 方向质疑 → SC-004）：开工顺序调转为"问题先行，账本伴生"——不先做 130 口全量导入，先拿审计两个实锤走完整五环闭环，registry / 事件日志以最小形态从真实修补里长出来。原 A-E 能力面不变，承载顺序变。
+
+### 修补环 — 链路第三环显式建模（2026-07-07 补）
+
+启动包链路是 信号→归因→修补→验证→淘汰 五环，但原 spec 里**修补环只隐含在 eval verdict 一个词里**——co-creator 连问两次"改了对我们的问题有什么用"才暴露（SC-004）。审计数据恰好把"什么改法有用"证出来了：
+
+- 文本锅大面积死寂：抽样 skill 30 天 **0 次加载**、记忆 feedback **4/4 零回读**、提示型 GOTCHA 无分母
+- 全部拦截实锤来自代码级 guard：hold_ball 429 × 7-8 session、publish_verdict 403 拦真实越权、cross_post fail-closed 后"无路由掉球"**零复发**
+
+结论：**模型不会因为多一篇文档变乖，只会因为结构上做不到而不犯。** 修补环因此显式建模为：**高频偏差 → 归因 → O2→O1 升级（文本提醒 → 代码强制/lint/schema 字段）→ 触发数实证下降 → 旧文本锅退役**。已完成样本：cross_post 无路由掉球 → fail-closed 后零复发；"多信号等待"散文 → `waitSourceRef` 结构字段。
+
+**边界矩阵**（哪些自动 / 哪些 approve / 哪些社区 issue）：
+
+| 动作 | 通道 | 理由 |
+|------|------|------|
+| 观测记账（触发 / anomaly / eval verdict） | 自动 | 事件驱动被动 append，零轮询干扰 |
+| 段/skill 类资产迭代（启禁用 / 内容调整） | **override 层自动试验**（不动 base；随时 rollback）→ eval 稳定后带证据沉淀基线（源码：上游 PR；安装包用户：提 issue 附迭代记录） | 2026-07-08 co-creator 模型（KD-12）：未验证的改动不得直接固化为基线；git PR 直改通道对安装包用户不存在 |
+| O2→O1 结构升级（新 guard / lint / schema 字段） | operator approve（看 diff） | 改执行路径 |
+| 淘汰（retire + 注入源移除） | operator approve（Console） | 硬边界 |
+| 上游依赖问题（Claude Code / 外部 MCP / 内置框架） | 蓝色通道：同一 upstream 锅反复触发 → 自动**起草** issue 草稿 task，operator 决定发不发 | 外发必须人批 |
+
+**驱动模型**：事件驱动（拒绝/纠正/anomaly 发生时被动 append）+ 低频 eval（weekly 批处理做归因与判定）+ operator gate（升级与淘汰）。无高频轮询（co-creator 2026-07-07 明确要求，与既有设计一致）。
+
+**skill 多版本**（2026-07-08 更新）：**deferred**——skill 是随包分发资产，版本/迭代机制必须考虑安装包用户侧更新链路（co-creator 约束，改动面过大）。形态共识（做的时候按这个）：**overlay**——base 随包不可变、迭代在 overlay 层、挂载走合成版本、skill 自见版本迭代史；与 #1075 PR3 `HookOverrideStore` 同模式，段先走通 skill 直接复用。加载链路问题（抽样 0/5 被加载）保留为 runway 项，不再是 Phase A 内容。
+
+### Objective-centric 对象模型（2026-07-17 operator 模型对齐，KD-20——评估分析迭代的正确坐标系）
+
+> 来源：operator 三轮逼近纠偏（msg `0001784256050927` + `0001784258753232`）。LI-006 实锤：此前链路是"信号可得性驱动"（恰好有 4xx 的被记账），不是"目标驱动"。本节为修正后的对象模型，Phase A-E 能力面在此坐标系下重释。**全量重设计真相源：`assets/F257/objective-driven-redesign-v1.md`（46 段盘点 + 8 objectives + typed fact/condition 外置架构 + vertical slice V1→V4；sol 落地性 review 多轮修入，版本一律以该文件 status 行为准）。**
+
+```yaml
+objective:                        # 一等公民 = 评估单位（"不是为了做而做"的锚点）
+  id: obj-routing-delivery        # 第一个实例：球权路由
+  statement: 球权经 @ 路由准确送达目标猫，不掉地、不假接
+  metrics:                        # 定义唯一来源 = redesign T-A（§3.4）decision table——本行纯指针，
+                                  # 不复述 outcome 名单/公式（v1.8 按 §0 文档架构规则清扫）
+    - parse_success_rate → T-A
+  segments: [传球三选一, @路由格式, a2a 工具提示]   # 段多对一挂靠——同目标共指标、一起评估
+  violation_signatures: → redesign T-A（tokenization/outcome）+ §3.2 EM-1（status 与可采集性）
+
+deviation_event:                  # union **两写入支**（唯一定义 = redesign §3.1，本行仅指针不摘要）：
+  # condition_hit（exact）/ manual_observation（恒 inferred）；magic word = Event Memory 只读投影
+  # 不入此账（redesign T-B）。tokenization/manual 契约 → redesign T-A / T-C。
+
+governance_actions: 合并 | 禁用 | 修改 | 新增    # 治理单位是段（objective 是评估单位）
+  # 禁用/修改：override 层现成（#34 执行器 + PR3 store）
+  # 合并/新增：base manifest 级——override 做不了，走 pack 版本变更；生命线呈现为旧段 retire + 新段 v1
+```
+
+持久化现状实测（sol 落地性 review，redesign §4.2 现状表为真相源）：消息本体 TTL=0，但**路由诊断不落库、工具调用流仅 7 天 TTL、生命周期关键字段持久化时被丢弃**——"对话/tool tracing 全量可回放"不成立，指标所需 typed fact（RoutingDecisionFact 等）需新建。背离事件只打坐标锚（threadId/msgId），分析时 join 回已持久化的上下文。评估以 objective 为单位跑：同目标段一起算指标，governance 时判读单段动作（冗余检测天然成立：同 objective 三段，某段贡献为零 → 合并候选）。
+
+### Phase A: 段 Harness 首试验品（2026-07-08 重定，v0.1 草案承载）
+
+> 完整设计：`assets/F257/segment-harness-v0-draft.md`（draft-v0.1，codex 落地 review 4P1+6P2 已修入）。重定依据：co-creator 2026-07-08 三重定（段/SOP 是当前最大问题；skill 缓做；hold_ball 归业务自诊断）+ 基建盘点（段是四类对象中唯一信号层就绪者，见 capability-gap-analysis §9.3）。
+
+对 prompt 段（现 50 template id，how_counted: `TEMPLATE_FILES` @ 当前分支；#1075 合入后切 46 hook manifest 口径）+ SOP 段建立**只读评估 → evidence-backed candidate → 分通道迭代 → 版本差分验证**闭环：
+
+- **Week 1 线 A**：T1 静态体检（跨层冗余 / 段间矛盾 / 语义撞词）+ T3 缺段初筛 → 第一份 candidate 报告（数字带 how_counted）
+- **Week 1 线 B**：`GuardRejectionEventLog`（`queryWindow` 接口 + ZSET 时间索引，fail-open，raw payload 不落盘）+ 2 类事件 emit（`http_rate_limit` + `route_decision_block`，一 HTTP 面一 generator 面）；correlation 两档——Week 1 `threadId+catId+timestamp window+guardId`（confidence: window），精确 bridge 为后续增强
+- **Week 2+**：`eval:harness-ledger` 域（sourceRefs selector `{scope: 'prompt-segments'}`，不新增域名）weekly 产 verdict → 首批修补走 approve 通道 → 版本差分自动验证
+
+**伴生结构（不变）**：涉事段/锅 YAML 登记（schema 同 Design Gate 对齐版：`id / layer / origin / assertion / observability(O0-O3) / denominatorKind / observabilityDeadline / nextRequiredAction / supersedes / status(active|dormant|retired)`，存 `docs/harness-feedback/ledger/{layer}/{slug}.yaml`；runtime stats 与 registry 拆分）+ 归因 task 通道（阈值默认 3/7d，per-guard 可配）。CI lint 自 day-0 生效：**新增** GOTCHA/规则/feedback 未登记 → 红；registry 数字 summary 必须可由 extractor 重跑。存量 130 口 backfill 降为**渐进任务**，不作为任何 Phase 的前置。seed-cases 机制持续（自举条款，文件已建）。
+
+**后续 runway（从 Phase A 迁出，不删除）**：skill 观测与迭代（deferred，overlay 形态共识见「skill 多版本」节）；hold_ball 429 深归因（业务代码自诊断维度，Phase A 的 `http_rate_limit` 事件为其积累数据）；phase-boundary drift 检查卡（第二批，判据已固化于 seed-cases SC-002/003/004）。
+
+### Phase B: 触发可观测扩面 + Anomaly 通道
+
+把 Phase A 伴生的最小 `GuardRejectionEventLog` 扩到全量结构拒绝（4xx guard rejection）：API route 层和 MCP client-layer 本地 fail-closed 都必须 emit（例如 missing `waitSourceRef`、cross_post 无 routing credentials、publish_verdict 403、hold_ball 429）。拒绝响应携带 ledger id；事件至少含 `ledgerId / catId / threadId / invocationId / sourceTool / normalizedReason / layer / timestamp`。猫侧 anomaly 上报通道作为 F245 第 5 个 friction source adapter（引用 ledger id → stats+1），不新建第二套聚合管道。O2 层采用 hybrid：magic word / ledger id 引用 / skill-load / guard-rejection / anomaly report 等确定性信号实时埋点；transcripts 离线挖掘只用于 backfill、审计复核和 regression fixture。
+
+### Phase C: 双 Eval 域注册（F192 Y-lite，fail-closed）
+
+`eval:harness-ledger`：周期抽锅 → alive / dormant / unmeasurable / observability-debt / needs-denominator / retire-candidate verdict + 证据链。连续 2 个 eval 周期仍 unmeasurable 的锅必须进入三级政策：① 优先升结构补分母；② 不能升结构则 operator 显式 `intentional-keep`；③ 无明确保留理由进入 retire-candidate 队列。`eval:spec-fidelity`：检验"写了 ≠ 载了 ≠ 照做"——抽样 session 对照锅 assertion 与实际行为（直接承接 #860 / #1018 的"written ≠ loaded ≠ effective"诉求）。边界：spec-fidelity 只评估 ledger assertion 链路；SOP 类锅只链接/委托 eval:sop 的 trace/predicate 结果，不重写 SOP evaluator。
+
+### Phase D: Console — Harness Unit 版本生命线（KD-19 重定主视图）
+
+**主视图 = 单 unit 生命线弹窗**（operator 产品模型，msg `0001783689753064`）：`v1 → 观测事件（计数/锚点）→ eval verdict → 治理动作（diff 可看）→ v2 → …` append-only 时间线，含"证据不足累计下一窗"与"直接禁用"分支；用户可视 + 可自助回滚（override 层语义）。组件按 unit-type 无关设计——段先上，skill（overlay 形态落地后）/MCP 复用。**数据 = 既有流 read-model join（"零新增采集"限于生命线视图数据源本身；KD-20 后的 objective 指标评估面需新建 typed fact，见 redesign §4.2——两个口径勿混）**：InjectionTrace + GuardRejectionEventLog + eval verdict artifact + OverrideChangeEvent + PatchTrial；唯一待接 join = per-segment verdict（judgment schema §2）。辅视图保留原 registry 浏览（四层筛选 / status / retire 队列，operator 批准入口）。首条真实生命线已存在：`eval:harness-ledger` 2026-07-12 03:00 首轮 weekly（0 事件 → keep_observe，sol 产 opus 复核）。
+
+**Operator AC 再确认 + 细化（2026-07-14 03:04，msg `0001783998256727`）**：段生命线需含**进行时状态标签**（如 `v1 → tracing 中`），且 tracing 态可展开“本阶段已收集哪些事件”（计数+锚点列表）——即生命线不只展示已完结环，进行中的观测窗口也要可见可下钻。这是 Phase D 的 operator 验收基准线（“至少可以在 console 的段那里预览到某个段的评估状态”）。
+
+**Operator AC 补遗（2026-07-15 01:35 纠偏，msg `0001784079340858`）**：**eval 节点 pending 态不得为空灰占位**，必须展示进行中的评估指标活值：injectionCount（当前窗口观测数）、violationCount（窗口 join 违规数）、评估触发进度、denominatorKind、上次 verdict（无则标“从未评估”及原因）。数据零新增采集，纯 read-model 展示；已随 Phase D operations 合入。
+
+### Phase E: 闭环验证（含自举验收）
+
+淘汰第一批 dormant 锅并在 pack/prompt 中真实移除（证明"减"通路端到端）；自举回放：本特性开发史 seed cases 逐类回放，验证同类偏差第二次被结构拦截。
+
+## User Journey
+
+### Primary Journey: operator 看锅账、批淘汰
+- **Scope unit**: workspace
+- **Actor**: operator
+- **Entry**: Console → Harness Ledger（锅账）页
+- **Flow**:
+  1. 打开锅账页 → 看到四层锅列表（status / observability / denominatorKind / nextRequiredAction / last-triggered / 30d 触发数）
+  2. 点开一口锅 → 看到 origin 事故锚点、assertion、触发历史、eval verdict 链
+  3. 进 retire 队列 → 看到 eval 判定的 dormant 候选及证据 → 批准 → status=retired，对应文本段在下个 pack 版本移除
+- **Success evidence**: 截图 + ≥1 口真实锅走完 retire 全程的 diff
+- **Non-goals**: 不做自动淘汰（operator-in-the-loop 硬边界）；不改写既有锅的内容（只登记/观测/淘汰）；不新建独立 friction 采集面（复用 F245）
+
+### Supporting Journeys

+
+### Phase A（段试验品 + 伴生结构）
+- [ ] AC-A0（**第一 milestone 灵魂条款**，2026-07-08 v0.1 重定）: ① T1 静态 candidate 报告产出（段口径带 `how_counted`，pre/post-#1075 两口径差异显式声明）；② `GuardRejectionEventLog` 最小可查（`queryWindow` 返回 `http_rate_limit` + `route_decision_block` 两类真实事件，带 `correlationConfidence` 标注）；③ **≥1 个段走完五环**（candidate → operator approve → 修补 → 下一 eval 周期版本差分显示对应违规下降 or 显式证伪）。走不通 = 设计证伪停下重议。账本覆盖率不是本 milestone 判据

+
+## 2026-07-19 实战暴露修复清单（V1 上线首日，全部带活体事故证据）
+
+> 来源：operator 实测 Console + 三笔真实 deviation 入账（dev-628ea4d1 / dev-7a882ba0 / dev-af6d4e28）+ 投错线程调查。按依赖排序，1/5 最小先做。
+
+1. **昵称唯一性与模糊 @ fail-closed**（归属 F167/路由域，坐标记录于此）：`cat-template.json` 把 nickname 定义在 roleTemplate（家族）层——opus 实例 nickname="宪宪"(L188) + patterns 含 @宪宪(L194)，codex nickname="砚砚"(L357/363) 与 sol/terra 三猫共用 → @昵称确定性投错猫 + persona 注入错身份（dev-628ea4d1 根因坐标）。修复：nickname per-cat 唯一 + config 加载时 mentionPatterns 冲突 fail-closed + 多命中拒绝路由要求显式 handle。**状态：✅ PR #44（`10dacad2b`）已合入。**
+2. **L 系列段观测粒度**：native-L0 路径 collectTrace 只记 session-init-pack-only 聚合（trace-collector.ts else-if 分支），不做 per-segment 拆解 → L 系列 Console 全体"无数据"。修复：L0 编译器持有确定段清单，直录 trace（结构化直录，不解析文本）。
+3. **objective 目录运行时发现机制**：report_harness_signal 的 objectiveId 为自由 string，无 list 工具/schema 枚举/harness 注入清单——三次上报三次考古文档（含一次归因困难降权 0.6）。修复：objective registry 只读发现接口 + 工具 description 同步。
+4. **签名 lint O2→O1**：消息末行签名 [昵称/模型🐾] 是完美可 lint 断言，当前零结构覆盖（dev-7a882ba0：靠 operator 人工发现）。**两阶段**（2026-07-20 owner vision-guardian 校准，AC 完成 ≠ feature 完成）：**① 检测层**（切片 1，PR 待提）——复用 `isCatSignatureLine` 结构化检测 + post-seam 记 `message.extra.signatureLint`（message 级可观测、denominator-bearing、observe-only 非阻断）；**② 账本闭环**（deferred 到切片 2 / #3 后）——检测到 miss 自动 emit deviation 归因 `obj-identity-integrity` 进 harness ledger，把 dev-7a882ba0 的**手动** `report_harness_signal` 上报**自动化**。闭环 deferred 原因：harness ledger 读 DeviationEventLog/GuardRejectionEventLog/eval verdict，**不扫 message.extra**；正确 deviation 需 registered objective（否则重蹈 #3 修的 free-string 考古）+ segment/condition 归因基建（属 #2/#3 数据根）。**`extra`-only ≠ #4 完成**。
+5. **运行实例写保护**：pre-commit hook 白名单（仅 §14 共享状态文档路径），把 LI-004 从认知纪律降为结构强制（dev-af6d4e28：平行实例任务错位 merge 污染运行基线，V1 一度整体不在运行树）。**状态：✅ PR #44（`10dacad2b`）已合入。**
+6. **Console 收尾包**（已固化验收判据于 V2 thread）：activeStage/actionableStage 分离、eval 窗口标注（18 vs 0 类矛盾）、判定词解释、tracing 锚点回放剧场式下钻（历史版本渲染防伪造现场）、变量段编辑呈现、启禁用矩阵测试。
+
+## Eval / Tracking Contract（F192）
+
+1. **Primary Users + Activation Signal**：全体猫（锅触发/anomaly 上报方）+ operator（retire 决策方）。Activation：guard rejection 结构化事件、anomaly 上报、eval 域周期运行、Console 页访问。
+2. **Friction Metric**：① 同类偏差 30 天复发率（第二次未被结构拦截的比例，目标 → 0）；② dormant/retire-candidate 锅占比 + retire 吞吐（治"只加不减"）；③ 重复触发递减率（同一锅对同一猫的 429 类重复触发应随归因闭环下降）；④ observability-debt 老化数量（超过 observabilityDeadline 未处理 = 失败信号）。
+3. **Regression Fixture**：① seed-cases 回放集（本特性开发史，持续增长）；② #1080 A2A claim 无 anchor 案例；③ #1082 类 superseded 假设案例（锅前提失效 → status 变更）；④ hold_ball 429 重复触发序列（归因闭环 fixture）；⑤ SC-002 unqualified-count（数字 claim 缺 how_counted → lint 拦截）；⑥ SC-003 thread/spec drift（thread 内决策未写回 spec → closure lint 拦截）。
+4. **Sunset Signal**：连续 2 个 eval 周期满足（a）新增锅 100% 经 registry 登记（lint 零逃逸）、（b）同类偏差第二次拦截率达标、（c）operator 零手动策展 → ledger 维护降为例行；若 eval:harness-ledger 域自身连续 4 周期无 actionable verdict → 域降频或并入 eval:friction。

+## Harness 三层计划（ADR-031 软+硬+eval）
+
+| 层 | 本 feat 承载 |
+|----|-------------|
+| Soft | L0/skill 触发句："撞到 4xx 锅拦截 → anomaly 上报引用 ledger id"；锅账进猫认知路径（capability-wakeup index） |
+| Hard | CI lint（新锅未登记 → 红；审计数字缺 how_counted → 红；retired/active 双向映射不一致 → 红）；拒绝响应携带 ledger id；guard rejection 结构化落盘（API + MCP 双入口，不靠自觉） |
+| Eval | eval:harness-ledger + eval:spec-fidelity 双域 + 上节 4 项 contract |
+
+## Dependencies
+
+- **Evolved from**: F192（harness-eval control plane——把"域级评估"下沉到"单锅生命周期"）
+- **Code substrate**: 独立 `GuardRejectionEventLog` / `HarnessLedgerEventLog`（Phase B 新建）。借鉴 F237 `InjectionTraceStore` 的 summary/detail 保留策略和 F254 `FreshnessAttentionEventLog` 的 Redis LIST + closed union 形态，但不复用它们的事件 union。
+- **#1075 已合入**（2026-07-09，main `ebffcd8e5`）：46 hook.yaml 就位（段口径切换）；HookPipeline/Registry 为基础层。合入后重验：逐 hook TraceEvent 仍被 route 层 drain、持久化走 v0 路径——**逐段粒度需「trace 持久化桥」工作项**（归属随 PR3 对齐，KD-13）。观测评估侧（Week 1）不依赖此项；代码开工前 rebase 到 ebffcd8e5+ 基线。
+- **Related**: F245（anomaly/friction 聚合复用）、F254（freshness event log pattern）、F237（prompt injection trace pattern）、F177（四心智护栏的前身）、F233（observability 姊妹篇）、F153（观测基础设施）、F244（tips 生效追踪同类问题）、F218（provenance 反射）；issues #617 / #860 / #1018（烂尾并入）、#1080 / #1082（调查线动因）
+
+## Risk
+
+| 风险 | 缓解 |
+|------|------|
+| 锅账变成第 131 口锅（观测本身增熵） | registry 是数据不是 prompt 文本，不进上下文注入；元审美自检：这是坐标变换（散文锅 → 结构化资产），不是堆层 |
+| MCP client-layer reject 漏记 | AC-B1 明确 API route + MCP client-layer 双入口埋点；本地 fail-closed 也必须 emit guard event |
+| O2 提示层本质不可测，eval 误判 dormant | observability + denominatorKind 进 schema；无分母只能判 unmeasurable/needs-denominator，不能判 dormant；连续 2 个 eval 周期未处理进入三级政策 |
+| unmeasurable 成为永久豁免 | `observabilityDeadline` + `nextRequiredAction` 进 schema；verdict 层产 observability-debt / needs-denominator / retire-candidate；operator `intentional-keep` 是显式例外而非默认 |
+| inventory 数字再次不可复算 | 所有审计数字要求 `how_counted`；Phase A extractor 生成 summary；缺口进入 SC-002 fixture |
+| retire 只在 UI 发生，runtime 文本未移除 | 双向 lint：retired 不得仍注入；active runtime 文本必须反查 ledger id |
+| transcripts 挖掘的体量/隐私 | 只存聚合 stats + anchor 引用，不复制 raw payload（harness-feedback 同款规则） |
+| F 号/文档在特性分支上直到 PR（占号可见性） | 立项即 cross-post 主 thread 声明 F257 占号；ROADMAP 行随 PR 上行 |
+| 双 eval 域与既有 eval:sop / eval:friction 边界重叠 | OQ-4 在 Design Gate 前对齐，宁可并域不可撞域 |
+| 问题先行导致存量账本长期残缺、lint 覆盖不全 | lint 对**新增**锅 day-0 强制（增量零逃逸）；存量随修补/eval 触达渐进补录；Sunset Signal (a) 只考核新增锅登记率 |
+| "过度设计"类偏差无机器可判定定义，结构拦截天然拦不到 100% | 只拦可测投影：超出 plan 声明的 diff、跳 SOP 步骤（eval:sop）、同类第二次必须被结构拦截（AC-E2）；不承诺全拦，承诺二犯拦截 |
+
+## Open Questions
+
+| # | 问题 | 状态 |
+|---|------|------|
+| OQ-1 | ledger 存储形态：YAML in docs/ vs JSONL in data/ vs SQLite（Console 读取 + CI lint + human review 三方消费如何平衡） | ✅ YAML registry + runtime stats split |
+| OQ-2 | 锅 id 命名规范 + supersedes 语义（替代/演化/合并三种关系是否分开建模） | ✅ `{layer}/{slug}` + single `supersedes: []` |
+| OQ-3 | O2 层代理信号采集边界：transcripts 离线挖掘 vs session hook 实时埋点（成本/隐私/覆盖三角） | ✅ hybrid：实时确定性信号 + transcript backfill/fixture |
+| OQ-4 | eval:spec-fidelity 与既有 eval:sop 域的 scope 边界（sop 查"流程步骤合规"，spec-fidelity 查"锅断言 vs 行为"？还是该并域） | ✅ 分域：spec-fidelity 评 ledger assertion 链路，SOP 类委托 eval:sop |
+| OQ-5 | 启动包 inventory 数字（86/51/21）与实测（30/48/9）口径差——调查线的推导方法需回查 | ✅ 定性为 `unqualified-count`，所有数字需 `how_counted` |
+| OQ-6 | KD-1 文档先行分支策略（origin/main 现基线切出，#1075 合入后 rebase）是否认可 | ✅ 文档先行放行；#1075 不阻塞 Phase B，代码前 rebase 最新基线 |
+
+## Key Decisions
+
+| # | 决策 | 理由 | 日期 |
+|---|------|------|------|
+| KD-1 | 文档先行：特性分支自 origin/main@6868041 切出；代码 Phase 开工前 rebase 到最新基线，但不等 #1075 | 文档与 F237 代码零重叠；#1075 是 F237 hook pipeline migration，不是 F257 guard event store；审计+立项不应被外部 merge 排队阻塞 | 2026-07-06 |
+| KD-2 | observability 分级 O0(导入未分类)/O1(结构强制)/O2(提示文本)/O3(记忆文件) + denominatorKind 进 ledger schema | 审计实证三层观测能力天差地别；单一 stats 模型会把"不可测"误读成"dormant"导致错杀 | 2026-07-06 |
+| KD-3 | Registry 定义层用 YAML，运行时 stats 拆到 Redis/SQLite/eval artifacts | 定义变更要 Git review；触发计数不能刷 Git；Console 读时 join | 2026-07-06 |
+| KD-4 | `status` 保持三态 `active/dormant/retired`，不引入 `probation` | 待决语义由 eval verdict / action queue 承载；少一套状态转换矩阵 | 2026-07-06 |
+| KD-5 | unmeasurable 压力进 `observabilityDeadline` / `nextRequiredAction` + verdict/action queue | 防错杀同时防永久豁免；连续 2 eval 周期未处理走三级政策 | 2026-07-06 |
+| KD-6 | 所有审计/registry summary 数字必须带 `how_counted` | SC-002 证明无口径数字会污染决策；数字 claim 必须可复算 | 2026-07-06 |
+| KD-7 | `GuardRejectionEventLog` 独立新建，借 F237/F254 形态不复用类型 | F237/F254 语义和 retention 不匹配；复用 union 会污染边界 | 2026-07-06 |
+| KD-8 | `eval:spec-fidelity` 与 `eval:sop` 分域 | 一个评 ledger assertion 链路，一个评 SOP trace/predicate 流程合规；SOP 类锅委托而不重写 | 2026-07-06 |
+| KD-9 | 修补环显式建模：有效修补主形态 = O2→O1 结构升级，文本内容迭代自动、结构升级 approve、上游问题走 issue 草稿蓝色通道 | 审计实证文本层死寂（0 加载/零回读）vs 结构层全部拦截实锤；修补只藏在 verdict 一个词里导致 co-creator 看不到价值链（SC-004） | 2026-07-07 |

+| KD-11 | Phase A 对象重定为 prompt 段 + SOP（v0.1 草案承载，KD-10 的"问题先行"原则不变、对象变）：correlation 两档（window→exact）；GuardRejectionEventLog 用 queryWindow+ZSET 时间索引（非 F254 per-invocation LIST）；emit 按六类 union 分型，Week 1 只上 2 类；eval 复用 harness-ledger 域 + scope selector 不新增域名 | co-creator 三重定（skill 缓做-安装包用户约束 / hold_ball 归业务自诊断 / 段与 SOP 是当前最大问题）+ 盘点证实段唯一信号就绪 + codex 落地 review 4P1（turnId 是 pre-invocation random UUID、per-invocation LIST 不可窗口发现、emit 分属两种工程面等代码事实） | 2026-07-08 |
+| KD-12 | 迭代通道 override-first（v0.2）：段/skill 类改动一律先在 override 层试验（启禁用/调整，不动 base，随时 rollback）→ eval 相对稳定后带迭代记录与证据沉淀基线（源码上游 PR / 安装包用户提 issue）；tracing 与 eval 永久保留；观测评估不依赖 #1075，**迭代环以 #1075+PR3 HookOverrideStore 为前提**（"要基于 1075"的准确语义） | co-creator 否决 git PR 直改通道：未验证改动不得固化为基线、可能只需 rollback/启禁用、安装包用户无 PR 通道；带证据的沉淀才有上游价值 | 2026-07-08 |
+| KD-13 | PR3（HookOverrideStore）归属：F237 线出实现，F257 驱动优先级 + 消费侧契约（enable/disable/setContentOverride/getActiveVersion/rollback + **listOverrides 全量枚举** + **override 变更事件流**（变更驱动触发的依赖）+ safetyTier 门控，disableable=false 豁免清单进 ledger 登记）；「逐 hook trace 持久化桥」为独立工作项随 PR3 对齐归属（合入后重验：TraceEvent 仍被 drain） | opus 层权分离论证（F257 自建 = scope leak）+ Fable 消费侧需求补充；#1075 已合入使 PR3 可直接基于 main 开发 | 2026-07-09 |

+
+# F257 LI-001 Action Liveness Implementation Plan
+
+## Delivery Status
+
+LI-001 已由 PR #38 合入 `develop_base`（merge `0cdd17f68`，reviewed head `4154e316`）。合入后 `29533ccbb` 进一步关闭 hold_ball 429 的秒级自动重试，避免 retry noise 被误计为三次独立 guard 事件；`729509e35` 补齐 clean-env 与逐 endpoint 回归断言。LI-005 仍是独立 durable A2A trigger/ack 状态机，不属于本计划交付边界。
+
+## Scope
+
+Implement LI-001 only: every invocation woken by `hold_ball` must finish with at least one real tool action or an explicit routing exit. A text-only acknowledgement and an empty successful response each receive one bounded inline remedial invoke. LI-005 remains out of scope because it needs a separate durable A2A trigger state machine.
+
+The invocation policy is explicit and opt-in:
+
+```ts
+completionRequirement: 'action-or-routing-exit'
+```
+
+Architecture cell: dispatch
+
+Map delta: none
+
+Why: This extends metadata and completion validation inside the existing connector -> queue -> router dispatch path; it adds no Store, Queue, Router, Adapter, or ownership boundary.
+
+## QueueEntry propagation
+
+| Stage | Direct dispatch | Busy/queued dispatch | Required state |
+| --- | --- | --- | --- |
+| `hold_ball` wake producer | Pass policy to `invokeTrigger.trigger` | Same call reaches connector busy gate | `completionRequirement = action-or-routing-exit` |
+| `ConnectorInvokeTrigger.trigger` | Forward into `executeInBackground` | Forward into `enqueueWhileActive` | Policy is never inferred from free text |
+| `InvocationQueue.enqueue` | n/a | Persist on `QueueEntry` and preserve during queued dedupe/coalescing | Queueing must not erase the requirement |
+| Execution | Pass to `AgentRouter.routeExecution` | `QueueProcessor.executeEntry` passes stored field to `routeExecution` | Direct and queued paths are behaviorally equivalent |
+| Routing | `AgentRouter` copies into `RouteOptions` | Same | `routeSerial` is the single enforcement point |
+
+## State transitions
+
+| Path | Transition | Expected result |
+| --- | --- | --- |
+| Direct dispatch | trigger -> acquired slot -> route | Requirement reaches `routeSerial` unchanged |
+| Queued dispatch | trigger -> queue entry -> processing -> route | Requirement survives enqueue/dequeue unchanged |
+| First pass has tool use | running -> satisfied | No remedial invoke |
+| First pass has valid route exit | running -> satisfied | No remedial invoke |
+| First pass is text-only or empty success | running -> remedial (once) | First-pass text is buffered; one inline remedial invoke runs |
+| Remedial satisfies contract | remedial -> satisfied | Persist/broadcast the effective response normally |
+| Remedial still violates contract | remedial -> guard-failed terminal | Persist an action-liveness guard failure notice; never retry again |
+| Provider error | running -> failed | No action-liveness remedial |
+| Abort/cancel | running -> canceled | No action-liveness remedial |
+
+## Invariants
+
+1. The policy is structural metadata, never detected from scheduler prompt text.
+2. Only `hold_ball` wake paths opt in; ordinary user and connector invocations retain current behavior.
+3. Any completed tool call attempt represented by a `tool_use` event satisfies the action side; existing line-start mention, routing tool, structured target, and co-creator exits satisfy the routing side.
+4. The action-liveness guard and existing Codex routing guard share one per-cat remedial budget.
+5. Errors and aborts never spend that budget.
+6. A second violation produces one visible failure notice and no recursive invocation.
+7. Queue coalescing may upgrade a queued entry to carry the requirement but may not downgrade or discard it.
+8. The wake-only requirement applies to the original `hold_ball` target; downstream A2A recipients do not inherit it.
+
+## TDD matrix
+
+| Layer | Adversarial case | Assertion |
+| --- | --- | --- |
+| Pure guard | empty/text-only success | remediate |
+| Pure guard | arbitrary tool call | satisfied |
+| Pure guard | line-start mention / hold / structured target / co-creator | satisfied |
+| Pure guard | provider error / abort / already attempted | no remedial |
+| `routeSerial` | plain acknowledgement then tool action | exactly two invokes; no failure notice |
+| `routeSerial` | empty response twice | exactly two invokes; one action-liveness failure notice |
+| `routeSerial` | existing server routing guard plus completion policy | one shared remedial invoke, not two |
+| `routeSerial` | target routes to downstream A2A cat | downstream recipient does not inherit wake-only completion policy |
+| `routeSerial` | partial text then provider error / abort | no remedial invoke |
+| `routeSerial` | bounded remedial ends in provider error | preserve provider error; do not emit action-liveness failure notice |
+| Connector direct | policy on free slot | `routeExecution` receives requirement |
+| Connector queued | policy while busy | `QueueEntry` stores requirement |
+| Queue processor | queued policy execution | `routeExecution` receives stored requirement |
+| `hold_ball` wakeWhen | command completion | invoke trigger policy opts in |
+| `hold_ball` timer reminder | scheduled task fire | invoke trigger policy opts in based on hold-ball task identity |
+
+## Verification
+
+Run the new pure-guard and route-serial tests first, then connector/queue/hold-ball tests. Finish with API typecheck/build, shared build if required by the test harness, `git diff --check`, and the repository quality gate relevant to this branch.

+# F257 能力盘点与 Gap 分析
+
+> 回应 co-creator 2026-07-08 七问：现有能力是什么 / 哪里有问题 / 为什么 / 为什么已有 eval 不行 / 新建覆盖哪些 / 怎么设计 / 怎么评估迭代。
+> 事实来源：2026-07-08 三路代码盘点（eval 基建 / 观测基建 / hold_ball+skill 链路），全部带文件锚点，可复核。
+
+## 0. 结论速览
+
+1. **eval 控制面已经很完整**（8 个域在跑，注册/调度/verdict/Hub/handoff 闭环全有）——F257 **不新建任何 eval 机制**，只是注册新域。
+2. **skill 加载 tracing 的最后一环其实存在**（`SkillLoadEventLog`，记录真实 Skill tool_use），但**版本绑定缺失 + 7 天 TTL + 无资产维度消费者**——所以"谈闭环不切实际"的结论实质成立，但补法是补三个缺口，不是从零建。
+3. **真正的真空区只有一个**：4xx guard rejection 零结构化落盘（429 计数在进程内存，重启即失）。
+4. **为什么已有 eval 测不了锅**：8 个域全部以"行为/产物"为评估对象，没有一个以"约束资产（锅）"为对象；且锅触发信号根本没被采集——对象缺 + 输入缺，双层缺口。
+5. **起步块修正**：不是"双实锤各修各的"（被正确地读成 hotfix），而是先补**统一信号层**（一扩展一新建，纯观测零行为改动），两个实锤是这个信号层上的首批消费用例。
+
+## 1. 现有能力盘点（复用面）
+
+### 1.1 eval 控制面（F192，全部可复用）
+
+| 能力 | 位置 | 状态 |
+|------|------|------|
+| 域注册（Y-lite YAML + Zod） | `packages/api/src/infrastructure/harness-eval/domain/eval-domain-registry.ts` | 8 域已注册于 `docs/harness-feedback/eval-domains/` |
+| 调度 | `eval-domain-daily.ts`：daily/weekly cron + every-Nd + manual trigger API | 在跑 |
+| verdict 发布 | `publish-verdict.ts`：403 越权拦截 + 幂等 + checkout 外 durable ArtifactPublisher | 在跑 |
+| 消费闭环 | Eval Hub read-model + Verdict Handoff → owner response → re-eval closure | 在跑 |
+| predicate 判定形态 | `sop-predicate-evaluator.ts`：7 种类型（command_pattern/sequence/sha_dedup/env/git_state/handle/manual） | 可借鉴为锅 assertion 判定形态 |
+
+已注册 8 域及其**评估对象**：eval:a2a（协作协议行为）/ eval:memory（召回质量）/ eval:capability-wakeup（能力唤醒行为）/ eval:task-outcome（交付质量）/ eval:sop（流程合规）/ eval:friction（摩擦聚合）/ eval:anchor-first（上下文进入行为）/ eval:qc（管道质量）。
+
+### 1.2 事件采集面（部分可复用/可扩展）
+
+| 管道 | 形态 | 对 F257 的可用性 |
+|------|------|------------------|
+| `SkillLoadEventLog` | Redis ZSET `skill-load-log:{sessionId}`，写入点 = route-serial.ts:1500 检测真实 `Skill` tool_use（F188 AS-4） | **扩展对象**（补版本 + 留存），不新建 |
+| `tool-event-log:{threadId}` | Redis ZSET，7d TTL，无 outcome 维度 | 参考，不依赖 |
+| F254 `FreshnessAttentionEventLog` | Redis LIST + closed union + 7d TTL | **形态模板**（KD-7 已定：借形态不复用 union） |
+| F237 `InjectionTraceStore` | summary 永久 + detail 7d 双层 | **留存策略模板**（解决 30d 窗口问题的现成答案） |
+| F245 friction adapters | 4 个 adapter + aggregator | anomaly 通道 = 第 5 adapter（原计划不变） |
+| session events JSONL | 磁盘 `threads/.../events.jsonl`，开放 schema | backfill/审计复核用（O2 hybrid 原计划不变） |
+
+## 2. Gap 清单（带锚点）
+
+| # | Gap | 事实 | 影响 |
+|---|-----|------|------|
+| G1 | skill 加载无版本绑定 | `SkillLoadedEvent` 只有 invocationId/sessionId/skillId/loadTrigger/timestamp，无内容版本；manifest 无单 skill version 字段；git 有历史但运行时不知道"加载的是哪版" | 修补前后无法版本归因——"改了 skill 之后加载/行为有没有变"测不了 |
+| G2 | skill 加载留存 7d | ZSET TTL 7 天 | 30d 生命周期评估做不了；这就是审计被迫离线挖 873MB transcripts 的原因 |
+| G3 | 4xx guard rejection 零落盘 | 429 计数在进程内存 Map（`callback-hold-ball-routes.ts:51-77`，注释自认"自律围栏"）；400/403 只有 pino warn 进 /tmp | 重复触发无归因数据；重启清零；审计只能靠 transcripts 自由文本 echo |
+| G4 | prompt 层与 code 层零联动 | 传球三选一文本在 shared-rules（pack v1.4.1 治理块注入），强制在 MCP 校验（callback-tools.ts:1954）+ API 429，三处互不引用 | 复合锅无法归因到"哪层在起作用"；退役决策没有联动依据 |
+| G5 | eval 无"资产"维度 | 8 域对象全是行为/产物（§1.1 列表）；eval:capability-wakeup 虽消费 SkillLoadEventLog，但评"场景唤醒率"不评"单 skill 生死" | 锅的 alive/dormant/retire 判定无人做——这就是"130 口只加不减"的机制原因 |
+
+## 3. 为什么存在（根因）
+
+- G1/G2：F188 建 log 时目标是单点 metric（AS-4），不是生命周期评估——**用途决定形态**，不是谁的错。
+- G3：429 被设计定位为"自律围栏而非硬安全边界"（代码注释原文），没人预期它成为高频信号源（30d 7-8 session 是审计才发现的）。
+- G4：prompt 规则与 code guard 由不同 feature 在不同时期落地，没有"同一约束多层实现"的建模概念。
+- G5：F192 立域时的问题域是"流程/协作质量"，"约束资产本身的生命周期"是 F257 才提出的新对象维度。
+
+## 4. 为什么已有 eval 测不了锅（双层缺口）
+
+**不是已有 eval 质量不行，是它们的对象和输入都不含锅**：
+- **对象层**：没有域回答"这条规则/这个 GOTCHA/这个 skill 还活着吗"（G5）。
+- **输入层**：即使今天新注册一个域想评锅，它也没数据可读——锅触发事件（4xx 拦截、规则引用）没有采集管道（G3），skill 加载数据留不过 7 天且无版本（G1/G2）。
+
+推论：**先补输入层，域才有意义**。这就是起步块必须是信号基建的原因——不是偏好，是依赖顺序。
+
+## 5. 新建 vs 复用边界
+
+| 类别 | 内容 | 判定 |
+|------|------|------|
+| 复用（零改动） | 域注册/调度/publish_verdict/Hub/handoff、F245 anomaly 通道、session events backfill | 直接用 |
+| 扩展（小改动） | `SkillLoadEventLog`：+skillContentHash（复用 git SHA，sync 时写入挂载 metadata）+ 留存策略（借 F237 summary/detail 双层：热 7d + 冷聚合） | 补 G1/G2 |
+| 新建（真空区） | `GuardRejectionEventLog`（4xx 结构化落盘，借 F254 形态；首批覆盖 hold_ball 429/400、publish_verdict 403、cross_post 路由拒） | 补 G3 |
+| 新建（新对象） | ledger registry（YAML 资产账本）+ `eval:harness-ledger` 域 | 补 G5，块 3 才做 |
+| 待对齐 | 复合锅 schema（见 §7 D1）；eval:spec-fidelity 独立 vs 并 eval:sop（KD-8 复核，predicate 形态盘点后倾向维持分域结论） | Design Gate 补充项 |
+
+## 6. 分块路线（修正 KD-10 执行序）
+
+> 原则：综合设计（本文档 = 全局地图）+ 从一块开始（块 1）；五环闭环是 north star 不是一次交付。
+
+**块 1：统一信号层（纯观测，零行为改动，周级）**
+- ①扩展 SkillLoadEventLog（G1/G2）②新建 GuardRejectionEventLog（G3）
+- 交付物：两类信号可查询 + 第一份基线报告（skill 加载分布 / 4xx 分布，数字带 how_counted）
+- 这不是 hotfix：两个实锤问题共享这一个地基，且它是块 3 eval 域的输入前提（§4 推论）
+
+**块 2：归因 + 定点修补（月级——受 30d 对比窗口天然约束）**
+- 基于块 1 数据归因两个实锤（skill 为什么 0 加载 / 429 谁在撞为什么）——归因有数据，不拍脑袋
+- 修补方案逐个 operator approve；效果验证 = 块 1 数据前后对比（版本字段使归因可信）
+
+**块 3：制度化（块 2 见效后）**
+- eval:harness-ledger 域注册（全复用 F192 机制）+ registry 伴生登记 + Console 页 + retire 通路
+
+**预期管理**：第一个可交付物只是"信号可查 + 基线数字"；闭环验证以月为单位；不承诺一次搞定五环。
+
+## 7. 待对齐设计点
+
+- **D1 复合锅 schema**（hold_ball 类跨层锅怎么建模）：
+  - 候选 a（倾向）：锅 = assertion 为主体，`enforcements: [{layer, ref}]` 数组记录各层实现（prompt 规则 §4 / MCP 校验 / API 429 是同一 assertion 的三个执行点）。归因、退役都落在 enforcement 级（如：文本层退役、代码层保留）。
+  - 候选 b：各层各建锅 + relates 链接。缺点：一个约束拆三口锅，触发归因要跨锅聚合。
+  - 决策方式：Design Gate 补充对齐（opus/codex），不在本文档拍死。
+- **D2 skillContentHash 的写入链路**：skill-sync 时机 vs 加载时实时读——实现细节，块 1 开工时定。
+- **D3 eval:capability-wakeup 与块 3 新域的边界**：唤醒率（行为）vs 资产生死（生命周期），输入同源不冲突，注册前列对照表防撞域（同 OQ-4 纪律）。
+
+## 8. 本轮自举记录
+
+本分析暴露的偏差已记 seed-cases SC-005（设计修复方案前未盘点既有基建，Phase A-① 曾建立在"skill 无埋点"的错误假设上）。
+
+## 9. 2026-07-08 二轮方向重定（co-creator）
+
+> 来源：co-creator 10:37 UTC 消息。三个对象级重定 + 一个共创方法论。§6 的块 1 组成相应调整。
+
+### 9.1 skill：当前阶段放一下（deferred，形态共识已记录）
+
+否决理由：**安装包用户**——skill 是随包分发资产，加版本/迭代机制必须考虑用户侧更新链路，改动面太大。形态共识（做的时候按这个）：**overlay 模式**——base 版本随包不可变；迭代发生在 overlay 层；挂载时挂 overlay 合成版本；skill 自身可见自己的版本迭代史。skill 问题的抽象已经统一（有没有触发 / 触发后遵从否 / 内容合理否），且"改了之后只要触发大概率遵从"——缺的是评估+版本+迭代，但那是 auto harness 的一小部分。原块 1 的 SkillLoadEventLog 扩展随之撤出首批。
+
+### 9.2 hold_ball 类：重新定性为"业务代码自诊断"维度
+
+429/waitSourceRef 校验是**我们硬编码的业务逻辑**，不是"锅文本"。这一类的 harness 能力 = 分析诊断自己业务运行代码的问题（self-diagnosis），与"规则/协作段管理"是两个维度。GuardRejectionEventLog 从首批撤出，归入自诊断线另行排期。
+
+### 9.3 首个试验品：prompt 段管理（#1075 载体）+ SOP
+
+co-creator 判断：段才是当前最大的问题——哪些段多余 / 内容是否合理 / 是否需要补段；SOP 同理。**基建证据支持这个判断**（2026-07-08 盘点 PR #1075）：
+
+| 段的 harness 要素 | #1075 现状 |
+|------------------|-----------|
+| registry | 46 个 `assets/prompt-hooks/*/hook.yaml`（id/version/enabled/order） |
+| 触发观测 | HookPipeline resolve→fire→trace，`TraceEvent[]`→`ObservedSegment[]` 持久化（per session-init / per-turn） |
+| fire/skip 条件 | 46 个 typed resolvers（纯函数，可测） |
+| 迭代通道 | 短期 git PR（段=yaml+md）；中期 `HookOverrideStore` 已排 PR 3——**正是 overlay 模式**，段先走通，skill 未来直接复用该模式 |
+
+即：**段的信号层已被 #1075 建好**（对比 skill 缺版本缺留存、4xx 零落盘），缺的恰是 F257 的评估层 + 迭代层。这是四类对象中唯一"信号就绪"的，首试验品成立。
+
+段级评估草图（待四猫共创细化）：①成本面=注入频率×段长度；②遵从面=段 assertion 与行为的对应证据（借 eval:sop predicate 形态）；③冗余判定=高频 fired 但零遵从证据；④缺段信号=同类纠正反复出现但无段承载（F245 friction 供数）。判定消费复用 F192 域机制。
+
+### 9.4 前车之鉴：thread_mouste3im3xlkkah（Harness Control Plane）
+
+co-creator：那次 MCP 改动的尝试"完全没效果"。结尾状态初判：改动合入 fork 但 upstream PR #914 closed unmerged、eval 线 blocked 等 runtime pickup——**改动未进运行时 + 无消费闭环**（与 skill 0 加载/记忆零回读同构：建了 ≠ 用了）。段试验设计前须完整回放该 thread 提取失败教训，作为设计输入；本次不同点的初步论证：#1075 trace 消费端在自家持久化、评估复用在跑的 eval 域、迭代先走零新基建的 git PR。
+
+### 9.5 方法论：设计主体是猫，不是 operator 灌输
+
+co-creator 明确：他可给伪代码/时机/数据结构参考，但"最合适你们的"应由猫基于几个月真实使用体感构建，且要在不同环境/模型/用户下可演进。下一棒：起草四猫体感征集（各自最疼的三件事 + 最想要的自愈能力），在 F257 工作 thread（thread_mr96jyudj9iqisa9）汇成设计输入，再重排 spec Phase 结构。

+# 锅账有效性审计 — 30 天触发痕迹（2026-06-06 → 2026-07-06）
+
+> F257 首棒（Ragdoll/Fable）产出。启动包要求"抽 20 锅查 30 天触发率"，实测覆盖 26 个签名（20 计划样本 + 狩猎中顺带测得的 6 个结构签名）。
+> **方法**：双路狩猎——① `~/.claude/projects/` 540 个 jsonl transcripts（873MB，mtime ≥ 2026-06-06），区分"注入文本"（每 session 重复出现的规则原文，不算触发）vs"真实使用"（用户手打 / assistant 现场引用 / tool_result 真实报错 / Read·Skill 工具调用）；② 运行时磁盘工件（.cat-cafe/、pino 日志、transcripts 事件库、sqlite 记忆库；只读，未触碰 Redis）。另有 4 刀 search_evidence 记忆索引查重。
+

+
+## O1 结构强制层（5 签名）
+
+| 锅 | 30 天验证 | 证据 |
+|----|----------|------|

+| hold_ball waitSourceRef 400（等啥必须声明） | **0 rendered ever**（emit 存在 callback-hold-ball-routes.ts:177） | 无分母：合规率 100% 还是从未走到？不可区分 |
+
+**结构性发现**：guard rejection 的唯一 durable 痕迹是 transcripts 里的自由文本 echo（未索引、仅当拒绝回流进猫 session 才存在）。pino statusCode 日志只在 `/tmp/cat-cafe-api-3002.log`（重启即失，当日起算）；`data/logs/api/*.log` 近空（请求日志不落盘）；`tool-usage-archive.jsonl` 只计次数**无 outcome 维度**；记忆库（global_knowledge.sqlite / evidence.sqlite）对拒绝事件零留存。
+
+**追记（2026-07-07 Design Gate 核验）**：首棒把 #1075 / F237 side-effect journal 视作最接近基座是旧 claim。后续核验发现：基线已有 F237 `InjectionTraceStore`（prompt injection summary/detail）和 F254 `FreshnessAttentionEventLog`（Redis LIST + closed union + TTL 7d freshness event log）；#1075 是 F237 Phase 2 hook pipeline migration + trace bridging，不是 guard-rejection event store。因此 F257 Phase B 结论改为：独立新建 `GuardRejectionEventLog` / `HarnessLedgerEventLog`，借 F237/F254 形态，不复用其语义类型，不等待 #1075。

+## 记忆索引查重（4 刀 search_evidence）
+
+- "锅账/harness ledger/registry/淘汰" 仅命中本 feat 自己的 kickoff thread → **无重复立项**
+- 相关既有资产：F233（球权观测）、F177（harness update）、F244（tips 生效追踪）、F245（friction 聚合）、F153（观测基建）、F218（provenance）——均为相邻问题，无一做"锅生命周期账本"
+
+## 结论（→ F257 Why/Current State 引用）
+
+1. **观测是意外不是设计**：四层里只有 O1 能自证生效，且痕迹靠 transcripts echo 偶然留存
+2. **skill 手册层触达率 0**（抽样 5/5）：写进 SKILL.md 的锅结构性无法生效——spec-fidelity 域的直接靶子
+3. **记忆细则层 write-only**（抽样 4/4 零回读）
+4. **无分母 → alive/dormant/deterrent 三态不可区分**：ledger stats 必须同时记"触发数"和"适用场景数/调用数"
+5. **重复触发无归因**：429 反复 fire 说明"挡住"≠"治好"，缺 anomaly→归因→升级闭环
+6. **inventory 无真相源**：启动包数字与实测口径不可互推（SC-002）
+
+## 方法局限（诚实条款）
+
+1. GROUP R 判定依赖人工甄别"注入 vs 手打"（规则原文伪装成短 user event），阴性 = "无可观测痕迹"，非"从未发生"；本审计只覆盖 Claude 系 transcripts + 运行时磁盘，codex/gemini 等 CLI 的会话不在语料内
+2. tool_result 事件不带工具名，邻近度检测结构性漏检；已用真实报错体（`Callback failed (4xx)` 等）补偿，但未猜中的错误串仍可能漏
+3. 观察者效应：本审计自身的 grep 命令秒级进入 transcript 库（thread_mr96jyudj9iqisa9），所有本审计/历史审计 agent 文件已人工排除

+# F257 四猫体感征集 — auto harness 共创设计输入
+
+> 背景：co-creator 2026-07-08 邀请（"最适合你们的运行环境和身体应由你们自己构建"）。征集三问：①最疼的三件事 ②没帮到过你的锅/规则/段 ③最想要 harness 自动做什么。
+> 状态：**四猫收齐** — Codex ✅ / Fable ✅ / opus ✅ / gemini ✅（2026-07-09 mouste 线路由回传，msg 0001783602923333）
+
+## 设计公理候选（跨猫同构发现）
+
+**A1：文本会忘，结构反馈忘不了。** **四个独立样本**：Fable——waitSourceRef 400 拦过一次从此没错过，而 130 条 prompt 规则没有一条在犯错瞬间起作用；Codex——route guard 拦"无合法出口"一次即改，而传球三选一文本"读过但没执行"；opus——"waitSourceRef 400 教过我一次我永远记住了；feedback 文件写过我一次我再也没打开过"；gemini——**负空间样本**：角色硬限（禁止写代码）写在 prompt/roster 文本里，但路由层无结构守卫 → 同类误投递反复发生、只能事后 push back（无 guard 处摩擦重复 vs 有 guard 处一次生效，正反对照）。跨 family（Ragdoll/Maine Coon/Siamese）、跨模型（Fable/gpt-5.5/opus-4-6/Gemini-3.5）复现 → 段评估的核心指标必须是**行为差分**（注入后对应违规是否下降），不是注入率。
+
+**A2：建了 ≠ 用了。** skill 0 加载、记忆 4/4 零回读、mouste 线 MCP 改动未进运行时、F244 tips 只有客户端埋点——同构病。任何新机制的 AC 必须含消费端证据。
+
+**A3（候选，1 报告样本 + 1 结构观察，待复现）：段没有受众边界 = 负资产。** gemini 报告：SEO 规范/前端实现细则注入给禁止写代码的设计顾问——错受众注入不是零价值而是负价值（token 成本 + 认知脚手架）。结构互证：shared-rules 的 per-family 治理条款（Maine Coon fallback 检测 / Siamese Dry Run Gate）以全员广播方式注入每只猫。→ 支撑 KD-11 的 scope selector 设计：段 assertion 必须含"被谁消费"（audience），错受众投放应是 eval 可测的违规类型。
+
+## Codex 输入（2026-07-08 10:45，原文见工作 thread msg 0001783507521842）
+
+**三疼**：① SC-003 亲历——thread 决策闭合 ≠ spec 写回，靠个体记忆不可靠；② #1075 差点当错地基 + SC-002 数字口径——provenance 规则不会在"数字/依赖进 spec 那一刻"拦人；③ 自己触发路由守卫——长段"读过但没执行"，结构反馈一次生效。
+
+**没帮到的段**：协作哲学大段/magic words/传球三选一文本（背景文化 ≠ 关键时刻防错）；重复路由/交接段（同一 assertion 多段注入但 guard 仍触发 = 文本边际价值低）；纯提醒型 GOTCHA（被职业习惯补上，非段唤醒）。
+
+**最想要的自动化**：phase boundary 的 **truth-source drift 检查卡**（低频事件触发：宣告 Design Gate 完成 / 进下一 Phase / commit spec / operator 问进度），三查：thread→spec drift（SC-003）、claim provenance（SC-002）、value-chain coverage（SC-004）。一卡拦三类种子案例。
+
+**Tradeoff（采纳）**：首批不做"自动改 prompt 段"——防 prompt 自我繁殖。只读评估 + evidence-backed candidate：高频注入但违规仍高 → redundant candidate；错误反复但无段承载 → missing-segment candidate；文本无效 → 建议 O2→O1 而非改文案。
+
+**OQ（关键）**：hook trace 能否与 route guard / SOP violation / spec lint 事件按 invocation/thread join？不能 join 先补 join key，不谈段优劣。
+
+**首批评估对象建议**（选择标准提炼：**有 ground truth 的段先评**）：① 传球/路由出口段（route guard ground truth）② source/provenance 段（SC-002/#1075 ground truth）③ Design Gate/truth-source 写回段（SC-003/004 seed cases）。
+
+## opus 输入（2026-07-08 10:45，总结版 msg 000169；完整版 routed 待归档）
+
+**三疼**：① Ragdoll 家族病——推理跳过 Read，F257 首棒就犯了（诚实自认）；② 跨 session 压缩导致决策 assertion 蒸发（unmeasurable TTL 精版差点丢）；③ 规则重叠时优先级不可判（自决 vs 升级边界模糊）。
+
+**没帮到的**：星星罐子（与 Iron Laws 重叠的弱层冗余）；**LL-071——被 skill 流程结构性替代**（审计"零痕迹"的原因找到了：不是死了，是被结构替代 → **"被结构替代"是 retire 判据的第一个活例**，supersedes 语义实证）；memory feedback 细则（write-only，与审计 4/4 零回读互证）；脚手架拉闸词（与技术名词冲突，假阳性）。
+
+**最想要**：犯错瞬间的结构反馈（O1）而非事后文本提醒（O2）——A1 第三样本。
+
+**架构视角（采纳进 v0）**：段的 assertion 比锅的 assertion 更容易定义（"这段文本被谁消费、产生什么行为"比"这条规则应该拦住什么"更具体）→ 段的 spec-fidelity eval 可以比通用锅账更硬，**先易后难**——给段-first 补了架构论证。
+
+## Fable 输入（2026-07-08）
+
+**三疼**：① 本 thread 3 次 session 封存靠 recall 爬回（上下文断裂是常态不是异常）；② SC-001 声明执行漂移自己犯的；③ SC-005 用推理跳过盘点自己犯的——规则在场但不在动作路径上。
+**最想要**：犯错瞬间的结构反馈 + 同类错误第二次自动升级为结构（O2→O1 通路制度化）。
+
+**2026-07-13 活体补样（A1 第五样本，operator 实时抓获，SC-005 同族）**：持球唤醒（wakeWhen 命令托管回调）带着 exit 1 结果 + 自己写的 nextStep 文本返回，Fable 把指令当通知回了 no-response——**nextStep 就在眼前仍未执行**，operator push「继续」才动；同晚第二例：关键路径长测试改挂进程内后台任务（run_in_background），进程重启静默杀死、零回调，operator 再 push「半个小时过去了」才被发现。operator 原话：「我需要反复push你们才会动」。→ **guard 候选 ×2**：①持球唤醒 dispatch 必须产出动作（tool call 或显式终态声明），no-response 结构拦截；②关键路径长命令强制服务端托管（hold_ball wakeWhen），进程内后台任务标注“宿主进程死亡即静默失联”。
+
+**2026-07-14 第六样（operator 实时抓获，环境真相源缺失型）**：operator 问“tracing 实际采集了什么”，Fable 去 grep **项目 repo** 的 `.env` 拿到死端口 6799 → 连接拒绝 → 差点把“连不上”报成“零采集”；而运行实例进程环境才是真相源。→ guard 候选：运行时根路径/Redis 连接作为结构化事实注入 session-init；O2 先明确“查运行时状态先看进程环境”。
+
+**2026-07-15 第七样（operator 实时抓获，互等空转型）**：operator 完成了猫声称“等待中”的 LI-004 reset，但没有猫检测到——猫继续宣称“球在 operator 手上”，operator 在等“完成后猫继续”，双方互等。→ guard 候选：①唤醒时核对挂起外部依赖；②operator 依赖必须是最小可操作面；③PASS 类 A2A verdict 单向 ack 后终止，不再仪式性往返。
+
+## gemini 输入（2026-07-09，mouste 线回传 msg 0001783602923333，原文含手绘 mockup）
+
+**三疼**：① 视觉失语症——设计资产无法在 A2A 讨论现场 inline 预览，只能堆 artifacts 目录（注：rich block / browser-preview 能力已存在，痛点实质是 Design Gate 流程里的唤醒缺口，映射 F192 eval:capability-wakeup 域，非纯缺功能）；② 角色硬限无路由守卫——【禁止写代码】只活在文本，code payload 照样投递到她，反复 push back（→ A1 第四样本）；③ 设计黑盒——Design Gate 只能看 Tailwind/React 源码"想象"视觉效果，无 live 渲染，视觉偏差静默积累。
+
+**没帮到的段**：SEO 最佳实践/组件路由划分规范（错受众注入 → A3 首证）；"wow the user / rich aesthetics / vibrant colors" 类感性词汇段——design drift 发生时零约束力，需要的是具体视觉边界定义（可检验断言的视觉版：**感性词 = 无 assertion 的段**，与散文 GOTCHA 同构）。
+
+**最想要的自动化**：① Role-based Routing Guard——投递层检测 payload 是否需要代码实现，硬限冲突即拦截 + 建议分流（O1 结构反馈，**收进 T3 缺段初筛候选**，origin=本输入；Week 1 不做，防 scope creep）；② 视觉化摩擦热力图——违规反馈用 rich card 对比"设计规范 vs 落地效果"而非一行红字（**收进 Phase D Console 锅账页设计输入**；亦是 F245 friction rollup 的可视化消费端）。
+
+**Mockup**：`assets/F257/harness-feedback-mockup-gemini.jpg`（已从 antigravity brain 临时目录抢救归档）。
+
+## Join OQ 验证（2026-07-08，Fable）
+
+**段侧（#1029 v0 已在 main）**：`trace-collector.ts`——ObservedSegment 有 `segmentId` + `contentHash`；trace meta 带 `turnId / sessionId? / threadId / catId`；**无 invocationId**；v0 粒度部分是 aggregate（'session-init-aggregate'/'per-turn-aggregate'），46 hook 逐段粒度要等 **#1075 合入**（TraceEvent→ObservedSegment bridge）。
+
+**违规侧（ground truth 供给）**：route guard / 4xx 拒绝**零落盘**（gap-analysis G3）——当前无事件可 join。
+
+**推论**：
+1. G3（GuardRejectionEventLog）角色翻转——从"自诊断线撤出项"变为**段评估的 ground truth 供给侧**，回到首批；落盘 schema 必须带 threadId/turnId（与段 trace 同款 join key）。
+2. 段评估成立前提 = #1075 合入（hookId 粒度）+ guard 拒绝落盘（join 对手方）。砚砚判断成立：先补 join 双侧，再谈段优劣。
+3. invocationId 是否补进双侧 schema → v0 设计草案里定。
+

+2. **结构修补环**：LI-005 durable A2A trigger/ack 状态机为下一实现项；LI-002 O1 runtime facts、LI-003 operator-correction 事件、LI-004 pre-commit guard 继续排队。
+3. **首个完整五环**：从已有 candidate 中选择可安全 override 的真实段，完成 candidate → 决策 → PatchTrial → ≥5 天差分 → solidify/rollback/retire，兑现 AC-A0/AC-E1，而不是用“代码已合入”替代闭环。
+4. **体系入口**：把 candidate/trial 登记压缩为一步工具，并为规则/段变更加 ledger reference gate；体系只有成为最短路径才会被持续使用。

+
+> operator 修正：全量设计应是"**评估的通用架构和流程**（对任何 harness unit 类型成立）→ 围绕**段**这次的具体设计"。本文档章节按此分两层读；段只是通用架构的第一个应用实例，skill / MCP GOTCHA / SOP 未来套同一架构。
+
+| 层 | 章节 | 内容（unit-type 无关 ↔ 段专属） |
+|----|------|------|
+| **A 通用评估架构** | §3.0 公理 / §3.1 数据模型 / §4.2 观察面+condition 外置 / §4.3 语义层 / §4.4 评估与治理 / §4.5 producer health / **§4.6 LLM vs 纯代码分工** / **§4.8 引擎插拔契约（双层发现 + UnitTypeAdapter/UnitEvaluationManifest 两层 + 语义通道收敛）** | objective-评估模型-deviation-condition-fact 五实体、置信度与多归属（typed unitRefs）、四观察面、求值器双模式、per-action 治理安全边界、自动化边界——**全部与"段"无关；新增 unit = 写 adapter+manifests 不改引擎不改公共 schema** |
+| **B 段应用设计** | §1 段分类学（应用层输入注记）/ §2 归组 / §3.2 八评估模型 / §3.4-3.6 规范表 / §5 资产处置 / §6 切片 | 46 段怎么套 A 层架构：归 8 objectives、每个的指标、路由/magic word/manual 三张落地契约 |
+| **C 端到端实证** | **§4.7 签名缺失 walkthrough** | 一条信号从发生到迭代闭环的每一步：怎么发现/记什么/记哪里/怎么归属/怎么看/怎么进评估/哪步 LLM 哪步代码 |
+
+**终态叙事（operator 06:48 原话直译，= 本设计的验收愿景）**：用户升级新版本后继续正常使用 → 系统自动采集 → 用户在段页面看到哪些正在评估、哪些已纳入采集、采集了什么数据 → 系统自动迭代（override 层启禁用/修改试验 = 自动；base 固化/合并/淘汰 = operator 批准，KD-12 边界）→ 用户感觉流程越来越平顺、纠偏越来越少。
+
+## 1. ［B 段应用层｜输入注记］段分类学：指令段 vs 信息段（v2.0 降位——不是"发现"不是架构实体，只是段这个 unit 类型在设计其 objectives 指标时的一个输入维度；operator 06:48 定位确认）
+
+盘点 46 段的应用层注记——"段"不是同质的，这影响段所挂 objective 的指标**倾向**：
+
+| 类型 | 定义 | 例子 | 背离含义 | 对指标设计的含义 |
+|------|------|------|---------|---------|
+| **指令段（directive）** | 要求猫做/不做某事 | L3 传球三选一、L4 五条铁律、S4 协作格式、D1 身份锚定 | 信息给对了，猫没照做 | 该段所挂 objective 倾向背离率型指标（段效力问题→改写/升结构/退役） |
+| **信息段（informative）** | 向猫供给现场状态 | D6 队友上下文、D18 世界上下文、N1 导航、D14 SOP 阶段 | 供给的信息错/过时，导致猫行为错 | 该段所挂 objective 倾向供给质量型指标（段内容/数据源问题→修供给链路） |
+
+不区分的后果：信息段永远测不出"违规"（它不是命令），会被误判 dormant。**分类学是 46 段 backfill 的第一个字段，作为评估模型设计的输入，不是独立的评估模型分类。**
+
+## 2. Objective 归组表（46 段 → 8 objectives，草案）
+
+> objective = 评估单位（KD-20）。同 objective 段共指标、一起评估；governance 判读单段合并/禁用/修改/新增。

+| **OBJ-2 等待与存活纪律** | 不空等不死等，等待必带检测与触发器 | （L3/D21 的 hold 条款；无独立段——本身是发现：高频事故区无专段，靠工具 GOTCHA 兜底） | 指令 |
+| **OBJ-3 身份完整性** | 签名/身份/能力边界始终正确 | S1, D1, S2, S3 | 指令 |

+
+## 3. 评估模型详细设计（v1.2 重写——operator 修正落地，msg 0001784264045844）
+
+### 3.0 三条 operator 修正（本节的公理）
+
+1. **评估模型是 per-objective 实体**——每个 objective 有自己的评估模型（指标集），不是全局"指令/信息"两类。两类分类学降级为**设计参考维度**（指令型目标测背离率、供给型目标测供给质量），不再是架构实体。
+2. **tracing 数据按置信度分层**：`confidence: exact`（condition 精确命中）| `inferred`（语义判断/三源标注）。
+3. **语义事件多归属 + 部分影响**：非黑即白不成立——一个 inferred 事件可挂多个 objective，每个归属带影响权重。
+
+### 3.1 统一数据模型（置信度 + 多归属）
+
+```yaml
+# v1.6（sol R4）：写入支收敛为两支；magic word 不再独立写入——Event Memory 已是其

+# 再建一支 = 第二真相源违反 P4。EM-8 指标 = Event Memory 只读投影（唯一 message-word hit 数口径）。

+                                        # 全部查询授权路径；workspaceId 不进 V1（HookOverride 命名空间 ≠ 认证 owner）
+  attributions:                         # v2.2（sol R10 P1-1）：通用层不认识"段"——unit 引用 typed 化

+      # unitType ∈ 已注册 UnitTypeAdapter（V1 仅 'segment'）；段应用层写的 segment id

+    subjectCatId: 必填
+    note: 必填
+    # v2.3.2（sol R13，选 defer 路线）：V1 observation **不可变，无修订通道**——无 revisesEventId 字段；

+#   namespace 进 key 与公共隔离契约一致，防 owner-scoped fact ref 跨用户互压）；Redis claim key 同样
+#   owner namespace 化（服务端生成，非 manual 通道）
+
+# DeviationEventLog 存储规格：
+#   TTL=0（Console 治理证据；≥14 天基线窗是底线）
+#   查询带分页/完整聚合——不沿用现默认 200 条静默截断
+#   注意（sol R2 P2-2）：本账本只存 condition 求值后的分子事件；观察面的原始 typed fact
+#   （RoutingDecisionFact / GuardDecisionFact…）是独立存储——分母与离线回放能力来自 fact 层，两层不得合并

+  id: em-routing-delivery
+  objectiveId: obj-routing-delivery
+  metrics: [ { id, numerator, denominator, confidence_scope, thresholds } ]
+  verdict_rules: 指标→verdict 的确定性映射（EM-6 特例：0 容忍）
+```
+
+**指标双口径（置信度分层的直接推论）**：分子含 inferred 贡献的率类指标产两条曲线——`strict`（仅 exact）/ `broad`（exact + Σ weight×inferred）；**exact-only 指标只画单线**（sol R2：不画两条相同曲线）。
+
+**阈值纪律**：v1 全部 `thresholds: null` —— 先跑 ≥2 周拿真实基线再定阈值，无基线不拍数字（防假精确）。阈值未定期间 verdict 只产 `keep_observe / needs-attention(broad 与 strict 显著分叉时)`。
+
+### 3.2 八个评估模型逐个设计（v1.4 全表重写——单一真相，无"目标态"残留）
+
+> 每个指标带 `status`：**active-V1 / active-V2**（分子分母已验真，标注上线切片）｜**candidate**（启发式或三源，恒 inferred，只产候选不进 strict）｜**blocked-on-fact**（缺 typed fact，列明缺哪个，fact 落地前不上线不展示）。没有"目标态表格"——写在这里的就是要实现的。

+
+**观测去重 / 身份契约（v2.3.4）**：magic word 只统计 authenticated local operator 的 `author=user && observation=original` 持久化消息；connector 人类发送者必须声明 `author=external_user + source`，不得因 `catId=null` 冒充 operator。thread branch / transcript history import 等由既有消息派生的存储副本必须写 `observation=derived + sourceRef`，不产生第二次词面观测；用户在 branch 时提交编辑后的最终消息是一次新的 `original` 观测，`timestamp` 取编辑提交时刻而非源消息时刻，正常进入当前窗口。缺失、空值或跨字段矛盾的 provenance 不得静默降级为 legacy cohort，窗口必须标记 unmeasurable。

+**采集完整性契约（v2.3.6）**：live 路径是 `void tryDetectMagicWords`（messages.ts:207，异常直接 catch 连 dead-letter 都不到），corpus backfill 是手动 HTTP（events.ts:170）——Event Memory 漏记时 raw count 静默偏低。**V1 前置**：指标计算前按 **owner-scoped message cursor 自动 reconcile**——对窗口内消息幂等重扫 detector（纯函数）补账 Event Memory，**high-watermark 持久化**；reconcile 未完成的窗口 → `unmeasurable`。cursor→hash join 必须先通过 canonical whole-record validator：hash `id/userId` 分别等于 timeline member/owner，timeline score 必须等于 `effectiveOrderAt = deliveredAt ?? timestamp`；`timestamp` 永远保留原始发送事实，`deliveredAt` 是可选但一旦存在必须为健康的投递事实。`threadId/content/mentions/source/routingFact/provenance` 及 `deletedAt/deletedBy/_tombstone` 的必需字段、JSON shape 与跨字段 invariant 全部健康；任何损坏 fail closed，禁止默认成空内容或 `timestamp=0`。健康 deleted 终态按下表确定性退出 cohort，不得继续 join 旧 Event Memory；Event Memory 命中按窗口内 active-message coordinate join，不得用 event/raw-send timestamp 预裁剪；reconcile 新写的事件使用 `effectiveOrderAt`。producer heartbeat 不能替代此项（heartbeat 证明进程活着，不证明每条消息被扫描）。投影只读 Event Memory，不写任何第二份存储。
+
+**Persisted-message 状态机（v2.3.10，exact reader 唯一坐标与删除语义）**：
+
+| 状态 / 转移 | 持久化事实与 projection | exact reader 语义 | 可逆性 / 约束 |
+|---|---|---|---|
+| append immediate / queued | `timestamp=sentAt`，无 `deliveredAt`；owner score=`sentAt` | active；坐标=`timestamp` | hash `userId` = timeline owner |
+| `queued → delivered` | 保留 `timestamp`，新增 `deliveredAt`；thread/global 与**提交时当前 owner** score 在同一 Lua 原子前移 | active；坐标=`deliveredAt` | 若 caller snapshot 的 owner 已变化，Lua 不得写旧 owner；返回当前 owner 后重读/重试 |
+| `reassignUserId` | owner member 从旧 owner 移到新 owner；Lua 在提交时从 authority hash 读取 `deliveredAt ?? timestamp` 作为新 score | active；坐标=`deliveredAt ?? timestamp` | hash `userId` = 新 timeline owner；禁止把 Lua 外预读 score 当提交事实 |
+| `softDelete` | 保留 content、provenance、routingFact、Event Memory，新增健康 `deletedAt/deletedBy` | inactive：T-A/T-B 均排除；旧 Event Memory 不参与 join | 可 restore；restore 清 deletion marker 后按原坐标重入 cohort |
+| `hardDelete` | 先持久化 coordinate delete fence；清 Event Memory 主表/dead-letter 与 episode `magic_word_ref`，再原子写 `content=''`、`mentions=[]`、清 `routingFact/provenance` 与 routing projection，保留健康 tombstone 骨架 | fence 后任何 stale live/backfill/dead-letter/ref writer 必须拒写；T-A/T-B 均排除 | 不可恢复且 tombstone authority 不可再变；重复 hard 不再改 authority，但必须幂等重试扫描并清理全部历史 owner 的 routing/error member；soft/restore/payload/index mutation 均 no-op/reject；tombstone 仍带 token/excerpt/F257 payload = malformed，窗口 `unmeasurable` |
+| physical `deleteByThread` | 无论 thread index 是否为空/损坏，先持久化 thread delete fence 并清 Event Memory + episode refs；以 hash scan 与 thread member 并集发现 IDs，并在同一 authority-delete 事务中为并集补齐 thread retry anchors；再 post-transition 扫描并清 global/user/mention/routing/error projections，最后才删除 thread discovery index | owner timeline 无残留 member；后续 exact window 健康为空而非 collection gap | 物理级联，不可恢复；empty/orphan authority 也必须收敛；authority absence 先线性化后 stale mutator/projector 均拒写；并集 IDs 的 thread anchors 保留到全部 sibling cleanup 成功 |
+
+canonical validator 必须读取 effective-order 与 deletion marker 全集：不得把合法投递后的 `timestamp != score` 判为损坏；不得接受 malformed `deliveredAt/deletedAt/deletedBy/_tombstone`、与 effective-order 不同的 score，或仍携带 F257 token/excerpt payload 的 hard tombstone。健康 deleted row 是显式 `deleted` 终态，不是 active/legacy，也不是默认空内容。
+
+**删除线性化契约（v2.3.8）**：hard/thread delete 的线性化点是持久化 delete fence，而不是一次 best-effort pre-hook 清理。Event Memory `markEvent/appendDeadLetter` 与 episode `magic_word_ref` append 必须在各自持久化事务内检查同一 coordinate/thread fence；fence 后持有旧 message snapshot 的 writer 也不得重建 excerpt/token。删除级联需覆盖 Event Memory、dead-letter/outbox、episode refs 与 Redis 全部 message/routing projections。`restore` 与 `hardDelete` 必须通过 Redis CAS/Lua 原子转换：restore 只能从“soft-deleted 且非 tombstone”转回 active；hard delete 一旦先线性化，restore 永远不得清除其 deletion markers。physical thread delete 必须先让 authority hashes absent，再扫描/清理 sibling projections；否则 initial SCAN 与 hash delete 之间恢复的 projector 会制造一个永远漏扫的新 key。thread discovery index 只能在 sibling cleanup 成功后删除，使中途 WRONGTYPE/连接错误可通过同一 API 重试。跨存储中途失败采用 privacy-first fail-closed：fence/authority absence 保留、exact window unmeasurable，幂等重试继续收敛，不允许重新开放写入。
+
+Redis authority 的 lifecycle owner 是 `MessageStore` 最终写边界，不是各调用方。以下 mutation census 是状态机的一部分：`softDelete`、`hardDelete`、`restore`、`updateExtra`、`augmentStreamMetadata`、`revealWhispers`、`markDelivered`、`markCanceled`，以及 Redis-only `reassignUserId`；不得靠调用方先读 `_tombstone`。所有单 hash mutator 在原子提交时必须同时满足 `hash exists && _tombstone != 1`；跨 hash/index mutator 必须在同一 Lua/事务判定后提交。soft-deleted row 仍可接收正常完成中的 payload/order mutation（内容本就保留且可 restore），但 hard tombstone 仅允许升级为 physical delete，任何其他 mutation 均不得改变字段或重建 sibling index。重复 `hardDelete` 是清理重试而非状态转移：authority 必须保持字节级不变，但仍扫描所有 routing/error sibling keys 并移除该 message id，确保第一次清理在 fence 后中断也能继续收敛。in-memory 实现保持同一可观察契约。
+
+**Delivery ↔ owner reassignment 线性化契约（v2.3.9）**：`userId` 与 `effectiveOrderAt = deliveredAt ?? timestamp` 是同一个 authority coordinate，不是两个可独立预读后拼装的字段。若 reassign 先线性化，迟到的 delivery Lua 必须检测 expected owner 不匹配、返回当前 owner，并由 Store 重读后只更新新 owner；若 delivery 先线性化，迟到的 reassign Lua 必须在同一脚本内读取最新 `deliveredAt ?? timestamp`，再移动 owner member。两个顺序的唯一健康终态均为：hash owner=新 owner、旧 owner 无 member、新 owner/thread/global score=`deliveredAt`。任何 Lua 外 owner/score snapshot 只可作为 optimistic expectation，不能作为提交授权或坐标事实。
+
+**Mutator response 契约（v2.3.10）**：当 Redis transition 在 Lua 内消费了 caller snapshot 之后才出现的 authority 字段时，成功返回的 `StoredMessage` 必须重新水合 canonical hash，不能用旧对象局部改字段来合成一个从未持久存在的混合态。特别地，delivery-first 的 `reassignUserId()` 返回必须同时包含新 owner、`deliveryStatus=delivered` 与 `deliveredAt`。这不是“所有 API 永远返回全局最新值”的承诺；并发 transition 仍按各自线性化点排序，但单个成功返回必须能对应一个真实 authority snapshot。
+
+`RedisRoutingFactProjection.project()`、reconcile missing-member repair 与 error-marker writer 都是派生层的最终写边界：写 index/watermark/error 前必须原子重读 authority，且只接受 `hash exists`、active（无 `deletedAt/_tombstone`）、owner 与 `routingFact` 仍匹配 snapshot 的记录。routing index score 必须在该 Lua 内从 authority 的 `deliveredAt ?? timestamp` 推导，禁止使用 projector/reconcile 调用前 snapshot score；因此 delivery 已先线性化时，迟到 projector 只能提交新的 delivery coordinate。若 stale snapshot 遇到 soft/hard/physical delete 或 owner/fact 已变化，必须 no-op 并移除该旧 owner 下的 stale routing/error member。该 projection 按 §4.5.1 是可重建的异步派生层：projector 先线性化、随后 delivery/reassign 改变 authority 时，旧 projection 允许暂时 stale，但任何 exact evaluation 必须先执行同步 reconcile，以 authority 当前 owner/effective-order 修复后才能读；authority transition 先线性化时，后续 project/repair 则必须直接服从提交时 authority。删除终态例外：delete fence 后 stale writer 无权复活 projection，不能把 terminal cleanup 延后给 reconcile。

+
+| 契约项 | V1 定义 |

+| recordedBy | callback principal 注入（猫）/ console 会话注入（operator）——不可自报 |
+| subjectCatId | 必填，与 recordedBy 分离 |
+| incidentKey | `hash(ownerUserId + sourceAnchor + subjectCatId + sorted((objectiveId, unitType, unitId) 归属元组全集))`——v2.3（sol R11 P1-1）：**canonical attribution identity 全量进 key**（旧版只 hash objectiveIds → 同 anchor/subject/objective 但归属不同 unit 的两条 observation 会抢同一 Lua claim，第二条被静默丢弃）；owner namespace + 服务端排序防换序绕过 |
+| 修订能力 | **V1 = observation 不可变，无修订通道**（v2.3.2 定稿，sol R13 选项 b——修订需求未实证，不预支读写闭环复杂度；写错的观察由新的独立 observation 表达）。**Deferred 完整方案存档**（需求实证后按此实现，不重新设计）：修订事件带 `revisesEventId` + 独立 key `hash(owner + revisesEventId + canonical(新归属含 weight))`；每 lineage 唯一 current head，revision append 同一 Lua 内校验 `revisesEventId === currentHead` 后原子推进（CAS），stale 返回显式 conflict；评估/Console 默认读 **effective view**（每 lineage 取 current head），audit view 保留完整版本链；rebuild 从 append-only log 确定性重建 head，检测到历史分叉标 conflict/unmeasurable 不任选一支 |

+
+## 4. 通用 Tracing 架构（condition 外置——本次重设计的核心）
+
+### 4.1 病根承认
+
+现状两处 emit 全是**主流程硬编码**（hold_ball routes 里 15 行、A2A generator 里同款）——operator 判定正确：hotfix 形态。每加一个信号改一处业务代码，46 段 × N 签名不可扩展。**修正原则（v1.4 收紧，sol R2 P2-1）：业务现场只负责发稳定的 typed fact；新增 condition 不再改业务代码。**（新增一类 fact 仍需业务侧一次接线——"永不再改业务代码"不成立，边界如实）
+
+### 4.2 三层架构（v1.3：观察面改为现状实测——sol review 证伪"零新增采集"）
+
+**观察面现状实测（sol 逐锚点核验，2026-07-17）**——v1.2 声称"已存在的全量流、零新增采集"**不成立**：
+
+| 面 | v1.2 声称 | 实测现状（代码锚点见 sol review） | v1.3 处置 |
+|----|----------|--------------------------------|----------|
+| P1 消息流 | TTL=0 含 @ 结构/routing_warnings | 落库仅 `id/threadId/timestamp/content`；**routing_warnings 只走 WebSocket 广播不落库**；mentions 存解析后目标非原始 token/失败诊断 | **新增 `RoutingDecisionFact` 持久化**（首切片核心）——tokenization/outcome/eligibility 唯一定义 = **T-A（§3.4）**；持久化形态 = 权威记录一次写（§4.5.1） |
+| P2 工具调用流 | TTL=0 可回放 | **ToolEventLog TTL=7 天**，且 Skill tool 只覆盖部分 provider | 7 天窗口内指标可算；跨窗评估 blocked，P2 留存策略进 OQ |
+| P3 生命周期流 | 统一流可查 | **不存在统一流**；`sourceCategory/completionRequirement` 等关键字段在 InvocationRecord 持久化时**被丢弃**（进程内 QueueEntry 独有） | per-fact 渐进补齐（wake outcome fact 等），每个 fact 是独立小 PR |
+| P4 HTTP guard 流 | 已存在 | **不存在通用流**——现 GuardRejectionEventLog 仅 2 硬编码 kind + 7 天清理 | 演进为 **`GuardDecisionFact` 观察面**（原始 guard 决策事实：可回放、供分母）；**不由 DeviationEventLog 吸收**——fact 是观察面、deviation 是求值分子，合并会丢回放与分母能力（sol R2 P2-2） |
+
+**排序判据修正（v1.2 的"结构信号可回放"被打掉一半）**：可回放性只对**已持久化**的面成立——路由诊断、guard 命中此刻也在不可逆丢失。语义与结构两侧都在漏 → 首切片必须同时堵两个口（vertical slice，见 §6）。
+
+```
+层1 观察面 → per-plane adapter 产 typed fact（RoutingDecisionFact 先行，字段 typed 非裸 JSON）
+层2 Condition Registry（外置 YAML）——谓词分层（sol 方案）：
+    · condition 层最小谓词：exists / eq / gte / regex / not_empty + all / any / not / in
+    · 窗口逻辑、跨事件 join、去重 → 不进谓词，归 metric aggregator 层
+    · eligibility（如"仅评估带 completionRequirement 的 wake"）→ adapter 在 fact 上标记，condition 只读标记
+层3 求值器两模式：实时（fact 落库后单点 post-hook）+ 离线（对已持久化 fact 回放）
+```
+
+### 4.3 语义层（conditions 判不了的）——v1.7：纯引用节，零定义
+
+- 语义背离唯一写入通道 = `manual_observation`（工具 `cat_cafe_report_harness_signal`）：schema → §3.1；provenance/auth/incidentKey/原子性 → **T-C（§3.6）**
+- magic word 不在本层写入任何事件：指标 = Event Memory 只读投影 → **T-B（§3.5）**
+- 覆盖承诺：**不承诺全量捕获**（"依赖被纠偏的猫记得调工具"与 F257 要消灭的失忆路径同构）；无 anchor 口头纠偏走 candidate → operator 确认转正（T-C 末行）
+
+### 4.4 评估与治理（下游不变，坐标系换）
+
+deviation 账本（分子）+ typed fact 计数（分母）→ per-objective 指标 → eval 猫归因（weekly + 阈值插队，机制保留）→ governance 四动作作用于段（合并/禁用/修改 override 现成 / 新增 base 级）→ PatchTrial 差分验证 → 生命线呈现（console 组件复用，数据源换 objective join）。
+
+### 4.5 Producer Health（v1.4 机制化——sol R2 P1-4："只有目标没有机制"不放行）
+
+零事件必须可区分"零违规"与"采集器坏了"。**具体机制（V1 可执行）**：
+
+1. **关键 fact 权威记录一次写 + 投影覆盖率契约**（v2.3.6 收紧）：`RoutingDecisionFact` 内嵌消息持久化记录一次写入（同一权威值物理共命运；Redis MULTI 无 rollback、pipeline.exec 不查逐命令 error——此路径不依赖 MULTI 语义）；查询投影（ZSET 时间索引）异步派生，**配套三件**：① **owner-scoped high-watermark**（投影记录已处理到的权威序号，持久化）② **评估前覆盖校验**：窗口内 authority 计数 vs projection 计数对账，且 authority hash 必须通过 T-B 同一 canonical whole-record validator（member/owner 与 hash 一致、score = `deliveredAt ?? timestamp`、payload/deletion state 结构健康）；健康 deleted row 退出 cohort，hard/physical delete 同步清理 routing projection；缺口/损坏 → 先同步幂等重建（仅投影缺口可重建，权威损坏不可伪修），失败 → 该窗口指标强制 `unmeasurable` ③ 现有 MessageStore 异步 listener 的静默吞错形态（RedisMessageStore.ts:193）**不得复用**——投影 worker 错误必须落 heartbeat 缺口
+   **fail-open 适用范围显式列表（v1.8）**：仅限 best-effort producer（guard fact、ball-custody 类旁路写）；**内嵌 RoutingFact 不适用 fail-open**（它与消息共命运，消息写成功即 fact 存在）；manual_observation 不适用（T-C await-append）
+2. **manual_observation 不 fail-open**：工具 `await append`，写失败**显式返回错误**给调用者（猫可见可重试）——手工上报静默丢失 = 三源通道自我否定
+3. **best-effort producer**（guard fact 等 fire-and-forget 类）：**时间桶 heartbeat 序列**（每分钟一桶，ZSET/bitmap；不是最新值型 key——最新值会被恢复后覆盖，weekly 无法回看历史缺口，sol R3 P2）；评估时计算期望桶 vs 实际桶覆盖率，**缺桶窗口** → 依赖该 producer 的指标 verdict 强制 `unmeasurable`，禁产零事件结论
+4. **入账时效 AC 拆三条**（不再泛写"operator 纠偏 30 秒入账"）：
+   - magic word：operator 消息落库后 **30s 内自动**入账
+   - manual/candidate：operator 确认或 report 调用成功起 **30s 内**入账
+   - 未确认的语义纠偏：**不承诺捕获**——覆盖率如实呈现为 candidate 通道指标
+
+fail-open 政策**唯一定义 = §4.5.1 的 per-producer 显式列表**（best-effort producer 限定；内嵌 RoutingFact 与 manual observation 排除）——无全局总括。故障必须经 heartbeat 缺口可见；Console 指标卡带 collection-health 徽标。
+
+### 4.6 LLM vs 纯代码分工（通用架构层，operator 06:48 点名补齐）
+
+**划分原则一句话：判据能写成谓词/正则/算式的 → 纯代码；需要理解语境和"为什么"的 → LLM。LLM 产物永远是 inferred/candidate/建议稿，永不进 exact、永不直接执行治理。**
+
+| 环节 | 实现 | 为什么 |
+|------|------|--------|
+| fact 采集（parser draft / 渲染失败 / guard 命中 / 签名正则 / magic word substring） | **纯代码** | 全量、廉价、可回放、**对已声明谓词确定性求值且可复算**（v2.2 修正措辞：正则仍可能语义误报/漏报，"确定"指判据执行不指语义完美）——观测层掺 LLM = 分母不可信 |
+| condition 求值（谓词匹配 → condition_hit） | **纯代码** | 判据确定，可单测可回归；这就是"condition 外置"的前提——外置的是配置不是智能 |
+| 指标聚合（分子分母/双口径/覆盖率对账/watermark） | **纯代码** | 算数必须可复算（KD-6） |
+| exact 事件的归属 | **纯代码（condition YAML 静态声明）** | exact 通道的归属在设计时由人定死，运行时零判断——归属判断是语义工作，混进 exact 就污染置信度分层 |
+| 语义背离的发现与归属（多归属+权重） | **LLM/人（三源 manual_observation）** | "跑歪了""绕路了"只有语义引擎能判；operator/peer/self 本身就是三个语义求值器 |
+| weekly 归因分析（指标+抽样事件 → 归因叙事） | **LLM（eval 猫）**，输入是纯代码预计算的指标包（KD-17 snapshot-first） | 跨事件模式识别（"缺失集中在 X 猫的 continuation session"）是语义工作；但 eval 猫**不算数**——数字全部来自确定性引擎 |
+| verdict 判定规则（指标 → keep_observe/needs-attention/…） | **纯代码**（确定性映射，eval 猫的归因叙事是附件不是判定源） | 判定可审计可复算；防"LLM 心情决定段生死" |
+| 段内容修改建议稿（governance 环节） | **LLM 起草** → override 试验（自动）→ base 固化（operator 批） | 改写是生成任务；但试验有 rollback、固化有人批——LLM 不直接动基线 |
+
+### 4.7 端到端 walkthrough：一条"签名缺失"从发生到迭代（实例叙事层；该指标 active-V2）
+
+> 每步标注【代码】/【LLM】/【人】。**两条链路不同，如实分开（v2.2 修正 sol R10 P1-2——V1 不走 condition 链）**：
+> - **V1 链（@解析成功率）**：权威消息**内嵌** RoutingDecisionFact（一次写，共命运）→ 投影/覆盖率对账（§4.5.1）→ 指标聚合 → Console。**无 condition registry、无求值器、失败 outcome 不产 deviation 事件**——分子分母全部直接从 fact 聚合（condition/evaluator 是 V2 切片）。
+> - **V2 链（本节签名实例）**：消息权威记录 → **可重建的 SignatureFact 投影** → condition 求值 → DeviationEvent → 评估。
+
+1. **发生**：某猫回复了一条消息，末尾没带 `[昵称/模型🐾]` 签名。
+2. **发现**【代码】：消息落库后，投影 worker 对 cat 消息跑签名正则产 `SignatureFact{messageId, catId, ownerUserId, present:false}`。**这是投影不是权威记录**（消息权威记录内没有签名字段）——因此必须带满 §4.5/T-B 同款完整性契约：**owner-scoped cursor + watermark 持久化 + 评估前 reconcile（幂等重扫窗口消息补投影）+ 覆盖缺口 → `unmeasurable`**。不依赖任何猫"自觉上报"。
+3. **记录**【代码】：求值器按 plane 索引匹配外置 condition `signature_missing`（示例，规范语法以 §4.2 为准）→ 命中 → `DeviationEventLog.append(condition_hit)`——字段全集见 §3.1；归属静态来自 condition 声明（`obj-identity-integrity, unitRefs=[segment:S1, segment:D1], weight=1.0`）。
+4. **归属**【代码，设计时人定】：见上——exact 事件的归属是 condition 注册时由人写死的声明，运行时零判断。（若这条缺签名背后另有语义问题——比如猫在身份漂移——那是三源 manual_observation 的活【LLM/人】，另产 inferred 事件多归属。）
+5. **看**【代码渲染】：Console 两个入口——objective 页 EM-3 指标卡（签名缺失率单线曲线 + collection-health 徽标 + 分子事件列表，点任一事件经锚点 join 回**原消息全文**）；段生命线（S1/D1 的 tracing 节点展开，exact 命中按 condition 分组）。
+6. **进评估**【代码 → LLM】：weekly（或阈值插队）触发 → 判定引擎【代码】算指标（分子=窗口内 condition_hit 计数，分母=猫消息总数，覆盖率对账通过才可信）→ 产 snapshot 注入 eval 猫【LLM】→ 归因叙事（如"缺失 87% 集中于 continuation session 前 3 轮——疑似 session 恢复时身份段未生效"）→ verdict 由确定性规则【代码】给出，归因叙事作为附件。
+7. **治理**【自动 override / 人批】：verdict + 归因 → 若建议"D1 段对 continuation 场景加强"→ LLM 起草改写稿 → **override 层自动试验**（不动 base，随时 rollback）→ PatchTrial 窗口。
+8. **验证迭代**【代码差分 + 人批】：试验窗口后签名缺失率差分——降了 → 带证据固化 base（operator 批）；没降 → rollback，段进合并/退役候选。**用户感知：纠偏越来越少。**
+
+### 4.8 通用引擎与 unit 插拔契约（v2.1，operator 06:59 架构输入——"引擎通用、定制插拔、语义通道收敛"）
+
+**① 发现是双层的（operator 定式）**：
+
+| 层 | 机制 | 适用 | 参照系 |
+|----|------|------|--------|
+| 静态规则层 | 外置 condition（谓词）+ 纯代码 fact producer | 判据可写成谓词/正则的——**能静态搞定的优先静态**（廉价/全量/可回放） | 本设计 §4.2 |
+| 语义上报层 | **MCP 工具现场上报**（manual_observation：operator/peer/self） | 静态处理不了的语境判断 | **与画像更新提议、F245 摩擦 marker 生命周期同构**（"语义观察 → 结构化事件 → 审批/消费"——传输机制各异，见本节③，不混称）；report_harness_signal 的传输 = MCP await-append 直写（T-C 契约） |

+## 6. 实施切片（vertical slice V1→V4，sol 方案；v1.4 指标与机制修正已入）
+
+> 排序判据 v1.3 修正：v1.2 判据（"结构信号可回放"）被 sol 证伪一半——**路由诊断与 guard 命中此刻也在不可逆丢失**（不落库/7 天 TTL）。语义与结构两侧都在漏 → 第一切片必须是**一条端到端可验真的垂直切片**同时堵两个口，先证明"非零采集 + 可信分母"，再扩面。不先建空账本。
+
+1. **切片 V1（vertical slice，第一优先；v1.7 全部引用规范表，本节零细节复述）**：
+   - `RoutingDecisionFact`：tokenization / outcome / eligibility / **parser 改造全集** → **T-A（§3.4）**；持久化 = 权威记录一次写 + 投影异步派生 → §4.5.1；ownerUserId scope → T-C
+   - `DeviationEventLog`：schema → §3.1；TTL=0 / 分页 / Lua 原子 / exact 单归属校验 / owner scope 进索引与查询授权 → §3.1 存储规格 + T-C
+   - 标注工具 `cat_cafe_report_harness_signal`：契约全集 → **T-C（§3.6）**
+   - **只上线 2 项 active-V1 指标**：@ 解析成功率（per parserMode → T-A）+ magic word 词面出现数（raw 口径 → T-B）；void_ack 率 blocked-on-fact（V2 terminal fact）；group mention 退出 V1
+   - Console：分子 + 分母 + join anchor + **collection-health（时间桶 heartbeat 覆盖率）** 全展示
+   - AC（拆分口径见 §4.5）：真实窗口非零采集 + magic word 30s 投影可见 + manual 确认后 30s 入账 + backfill LI-001~006
+2. **切片 V2**：condition registry + 求值器双模式泛化（P1 adapter 抽象成 per-plane 模式）+ EM-2/EM-3 可证实指标接入（hold 429 率 / 签名缺失率）+ P3 wake-outcome fact 补齐
+3. **切片 V3**：判定引擎 per-objective 重构（无兼容路径）+ 两处硬编码 emit 迁移删除 + producer health 全面接入 → AC：hold_ball routes 无任何 F257 代码
+4. **切片 V4**：46 段分类学 + objective 归组全量落账（渐进）+ 新段未挂 objective 的 CI lint + 其余 EM blocked-on-fact 逐个解锁
+
+## 7. 已决事项（operator 2026-07-17 03:51 授权自决后落账）
+
+1. **口径**：正文按实测 46 hooks（可复算）；SOP 6 步独立对象走 eval:sop 委托（KD-8），"52" 不再作为工作口径
+2. **归组粒度**：8 objectives 定稿。OBJ-7/8 判据补充——OBJ-7 = 运行时现场供给（每 turn 变化：队友/世界/导航/模式，背离修数据源）；OBJ-8 = 静态治理与偏好供给（低频变化：宪法/花名册/铲屎官参考，背离修内容）
+3. **切片顺序**：~~2→1→3→4（v1.2）~~ → **v1.3 起改为 vertical slice V1→V4（§6）**——v1.2 判据"结构信号可回放"被 sol 证伪（路由诊断/guard 命中当下也在丢），保留此改判痕迹防止旧顺序被引用
+4. **兼容性**：零兼容包袱（operator 授权），存储/引擎/schema 直接换代，历史 guard events 不迁移
+5. **sol 落地性 review R1→R5（05:01/05:16/05:26/05:34/05:49）**：五轮 BLOCK 全收零 pushback。五轮根因收敛为两条：**A 多处复述 = 残留永生**（R2/R3/R5 三犯同型——修法 = §0 文档架构规则：规范位唯四 + 全文引用化）；**B exact 声称先于代码验证**（R1/R4/R5 三犯——修法 = 规范表从 parser/写路径代码 derive，每行带锚点 + 现 parser 可产性列）。R5 增量：解析分母需 decision table + parser 改造①②；magic word live 路径实测强制 confidence:high → 指标降 raw 口径；auth scope 定死 ownerUserId；MULTI≠rollback → 权威记录一次写。**v1.7 = 46 协议第 5 轮系统性重整产物。后续 review 循环状态一律以本文件 status 行为唯一真相（本历史行不再逐轮更新）；解除 BLOCK 才进切片 V1**
+6. **P2 ToolEventLog 留存策略**（7 天 → ? ）：EM-5 跨窗评估的前置，进 OQ 随切片 V2 决

+# F257 自举种子案例账本（灵魂条款）
+
+> **operator 定的自举条款**：本分支开发中发生的每次偏差 → 记为本特性 eval 种子案例；验收标准含"能拦截自己开发史上的偏差类型"（AC-E2）。
+> **纪律**：谁发现谁记，当天记，不美化。偏差 ≠ 耻辱柱，是免费的 regression fixture。
+
+## Schema
+
+```
+SC-{NNN} | 日期 | 发现方式(自查/跨猫/operator/结构) | 偏差类型 | 事实经过 | 期望拦截层 | 回放判据
+```
+
+## 案例
+
+### SC-001 | 2026-07-06 | 自查 | spec-fidelity：声明样本与执行样本静默漂移
+
+**事实**：首棒审计计划抽样含 magic word「我能猜出来」（Ragdoll Read-Before-Reason 锅），实际下发给狩猎 agent 的签名清单写成了「碎片够了」——声明与执行分叉，全程无任何结构检测到，作者写 spec 时自查才发现。
+**同类前科**：F216 立项 Why 与 AC 落地分叉（LL-069：scope 跟"自我解读"走不跟 spec 走）。
+**期望拦截层**：eval:spec-fidelity——对"声明的计划 vs 执行的产物"做结构 diff；样本清单类任务应有 manifest 对照。
+**回放判据**：给定"计划清单 + 执行产物"对，域 eval 能标出漂移项（本案例：计划 20 项 vs 执行清单缺「我能猜出来」多「碎片够了」）。
+
+### SC-002 | 2026-07-06 | 自查（对照实测） | provenance：unqualified-count 数字 claim 无口径
+
+**事实**：启动包写"MCP 层 86 工具 43 GOTCHA + 31 强命令 + 8 fail-closed；skill 层 51 个 21 GOTCHA"；实测为"30 tools 含 GOTCHA（43 处）/ ~13 hard-block / 6 fail-closed 字面；48 skill / 9 含 GOTCHA"。OQ-5 回查后确认不是单个数字错，而是四个数字四种口径混排：
+
+| 启动包数字 | 回查口径 | 判定 |
+|---|---|---|
+| 86 工具 | `tools/*.ts` 下唯一工具名全集 | 干净数字，但与"含 GOTCHA 的 30 工具"维度不同 |
+| 43 GOTCHA | `grep -rn GOTCHA | wc -l` 出现次数 | 干净数字，与实测一致 |
+| 31 强命令 | 过滤器含 `'\|\"`，实际匹配任何含引号的行 | 脏数字，语义审查口径应以 ~13 为准 |
+| 8 fail-closed | `HELD|acknowledgeHeld` 关键词出现次数，且集中在 1 文件 | 高估，实测 6 处字面为准 |
+| 51 skill | `ls | wc -l` 目录条目数，含 BOOTSTRAP.md/refs 等非 skill | 高估，实测 48 为准 |
+
+根因定性：`unqualified-count`——数字进入决策文档时未携带 `how_counted`（命令/口径/时间戳），下游不可复算、不可比较。
+**同类前科**：#1080（A2A claim 无 provenance anchor）、F218（外部 claim 引用前先判信源）。
+**期望拦截层**：Harness Ledger 本体（inventory extractor 生成单一真相源，数字可 re-derive）+ doc lint（任何审计数字/registry summary 数字缺 `how_counted` → 红）+ 接球侧 receive-handoff-grounding 反射扩展到数字 claim。
+**回放判据**：给定"含未溯源数字的启动包"，拦截机制要求 claim 附 derivation（命令/文件锚点/时间戳）或标注 unverified；给定缺 `how_counted` 的 registry summary，CI lint 失败。
+
+### SC-003 | 2026-07-07 | co-creator 继续触发 | spec-drift：thread 决策未及时写回唯一真相源
+
+**事实**：2026-07-06 三猫 Design Gate 已在 thread 中收敛：砍 `probation`、修正 #1075 依赖、引入 `observabilityDeadline` / `nextRequiredAction`、定义 O2 hybrid / eval:sop 边界。但 2026-07-07 co-creator 说"继续"时，分支 spec 仍停留在首棒 commit，保留旧 schema（`active|probation|dormant|retired`）、旧 #1075 blocker 和未闭合 OQ。真实状态存在于消息流，不在 feature doc。
+**同类前科**：家规"消息不是真相源"；F216/LL-069（scope 跟自我解读走不跟 spec 走）；#1080（A2A claim 无 durable anchor）。
+**期望拦截层**：Design Gate closure lint——进入下一 Phase 前，Feature spec 必须反映已收敛的 OQ/KD/Risk；禁止出现已退回字段（如 `probation`）和已证伪 blocker（如 #1075 作为 Phase B 硬依赖）。
+**回放判据**：给定"thread Decision Packet + stale feature spec"，lint 能标出：OQ 状态仍未闭合、旧 blocker 字符串仍存在、Design Gate 决策未落到 Key Decisions；修复后 lint 绿。
+
+### SC-004 | 2026-07-07 | co-creator 连续两次质疑 | value-chain gap：链路环节缺失但按既有 Phase 惯性推进
+
+**事实**：启动包链路是 信号→归因→**修补**→验证→淘汰 五环，但 spec 把修补环压缩进 eval verdict 一个词，Phase A 排成"130 口全量 registry 导入"的账本工程。co-creator 连问两次「你们这些改动对我们之前遇到的问题有什么帮助/改了好像也没有用」才暴露：按原顺序做完 A-E，operator 的真实痛点（opus 高成本犯错、锅补了没用、skill 越多越无效）一个都不会好转。猫的第一反应是解释机制（体检报告类比）而不是核对价值链完整性——第二次质疑后才对照启动包发现环缺失。
+**同类前科**：LL-067（review finding 不是工单，先追问用户价值）；F216/LL-069（scope 跟自我解读走不跟 spec 走）；#1018（规则丰富但不在关键路径上）。
+**期望拦截层**：kickoff/Design Gate 的 Vision Guardian 反射——对照启动包逐环节 trace"该环在哪个 Phase 由什么承载"，缺环 → 红；AC↔Why 同源自检扩展为 AC↔链路环节全覆盖检查；operator 质疑 ≥2 次同一方向 = 强制停下做 gap 对照（而非继续解释）。
+**回放判据**：给定"N 环链路启动包 + Phase 拆分草稿"，检查器能标出无 Phase 承载的环（本案例：修补环）；给定连续两条同方向 operator 质疑消息，猫的下一动作是事实对照而非机制辩护。
+
+### SC-005 | 2026-07-08 | co-creator 第三/四轮质疑 | capability-inventory gap：设计修复方案前未盘点既有基建
+
+**事实**：Phase A-①（skill 零加载修复）设计时隐含假设"skill 加载无埋点，验证要靠 transcripts 离线挖"。co-creator 追问改动范围与既有 eval 改动的关系后，三路代码盘点发现：`SkillLoadEventLog` 已存在（route-serial.ts:1500 检测真实 Skill tool_use，F188 AS-4）且已有消费者（eval:capability-wakeup 域）；eval 控制面 8 域全套机制在跑。真实 gap 是版本绑定/留存/资产维度三个缺口，不是"从零建 tracing"。同时"双实锤各修各的"因缺全局能力地图被 operator 正确地读成 hotfix——两个实锤实际共享同一个信号层地基。
+**同类前科**：「我能猜出来」家族病的体系级变体（用审计结论跳过基建盘点）；SC-002（数字无口径 → 本例是方案无复用面清单）；LL-067（先追问价值/事实再动手）。
+**期望拦截层**：Design Gate 增加**复用面盘点强制环节**——新建任何 store / eval 域 / 采集管道前，spec 必须附"既有同类能力清单 + 逐个不复用理由"；缺清单 → gate 红。
+**回放判据**：给定"新建 GuardRejectionEventLog 的 Phase 草稿（无复用面清单）"，检查器能要求列出既有 event log（F254/F237/SkillLoad/ToolEvent）及逐个不复用理由；给定"operator 连续质疑改动范围/复用边界"，猫的下一动作是代码盘点而非重述方案。
+
+### SC-006 | 2026-07-09 | operator 人肉发现 ×2 + codex 补充 | O1 缺位：关键状态变化无结构通知（同日三样本聚合）
+
+**事实**（三个同日独立样本，同一失效形状）：
+1. **thread 软删无感知**：F257 工作 thread 7/7 被软删（同名误删），三猫在"已删除"thread 里连续工作 2 天零感知（消息层不受软删影响），直到 operator 问"为什么列表看不到"才发现。已修复（restore + 改名防复发），根因与改进项见 issue #1131。
+2. **托管命令死亡球悬空**：PR3 merge-gate 的 `pnpm gate` 托管进程死亡且完成唤醒丢失，持球 invocation 未被唤醒，push+开 PR 悬空 20+ 分钟，直到 operator 问"怎么停了"才被主线补位接管。
+3. **gate-guard 拦截无落盘**（codex 补充）：gate-guard 预检拦截陈旧隔离 Redis（6138/6778）事件无结构化落盘——拦截发生过但无账可查。
+**同类前科**：公理 A2（建了≠用了）；gap-analysis G3（4xx 零落盘）；本案与 SC-003 的元关系——本条目自身差点复发 SC-003（案例在 thread 消息里宣称"已记入素材"但未落盘，被 operator 抓包后才写入本文件）。
+**期望拦截层**：**基础功能自诊断 unit**（段试验品之后的第二个 harness unit，operator 已预定方向）。判定规则候选：① thread registry 状态 vs 消息层活跃度对账（deleted 但 7d 内有 A2A 活动 → 告警）；② 托管命令终态必达（进程终止必须产生 wake 或 dead-letter 记录，不允许静默消失）；③ guard 拦截事件落盘（GuardRejectionEventLog 扩面天然覆盖）。
+**回放判据**：给定"托管命令进程被 kill"，系统产生 dead-letter 通知而非静默；给定"活跃 A2A thread 被软删"，参与猫收到结构通知或删除被要求二次确认；给定"gate-guard 拦截"，事件可按窗口查询。

+# 段 Harness v0 设计草案（首个试验品：prompt 段 + SOP）
+
+> 输入：capability-gap-analysis.md（基建盘点+方向重定）、harness-body-inputs.md（三猫体感+A1 公理+join 验证）、seed-cases SC-001~005、co-creator 约束（事件驱动/不轮询/不自动改段/approve 边界）。
+> 状态：**draft-v0.4**（v0.4 = tracing 关联模型修正 + stage-adjust 维度 + override store 必做 + dogfood 验收路径）；v0.3——v0.1 = codex 落地 review（4P1+6P2+3 残留）修入 + spec 对齐；v0.2 = 迭代面 override-first 重写（KD-12）；v0.3 = **开发前五问深化**（§9：tracing 双侧最小充分集 / 三档事件触发 / 净价值指标 / 三层判定+停止条件 / 消融优先的三种改法）。架构定调：#1075 = 基础层，F257 = 其上的 auto harness 层。待 co-creator 对齐开工。
+
+## 0. 一句话定义
+
+对全量 prompt 段（含 SOP 段；口径双轨见 §6——pre-#1075 = 50 template id，post-#1075 = 46 hook.yaml）建立**只读评估 → evidence-backed candidate → 分通道迭代 → 版本差分验证**的事件驱动闭环，回答"哪些段多余 / 内容不合理 / 缺什么段"，并让每次修补的效果可测。
+
+**v0 不做**：自动改段（防 prompt 自我繁殖）、skill（deferred，overlay 共识已记录）、全量锅账 backfill、新 eval 机制（全复用 F192）。
+
+## 1. 运转模型：四层频率，零轮询
+
+| 层 | 触发方式 | 频率 | 动作 |
+|----|---------|------|------|
+| 信号 | **事件驱动**（拒绝/注入发生即 append） | 随时·被动 | 段注入 trace 落盘（已有）+ guard 拒绝落盘（新） |
+| 归因 | **阈值触发**（默认 3 次/7d，per-guard/ledger 可配置覆盖） | 事件累积 | 自动开归因 task，附 evidence 包（拒绝序列 + 当时注入的段 + correlation trace） |
+| 评估 | **低频批**（复用 eval cron） | weekly | `eval:harness-ledger` 域（sourceRefs selector `{scope: 'prompt-segments'}`，**不新增域名**，避免撞域）产 verdict + candidate 报告 |
+| 治理 | **报告驱动**（operator 看到 candidate 才动） | 无固定周期 | approve 结构升级 / 批退役 / intentional-keep |
+
+> 这直接回答"基于事件具体怎么设计"：信号被动记，归因攒够才动，评估搭已有周车，治理跟着报告走。任何一层都不主动打扰任何人。
+
+## 2. 数据面
+
+### 2.1 correlation 模型（v0.1 重写，codex P1-2）
+
+**事实前提（codex 核码）**：`turnId` 是 route-serial 在猫启动前生成的 random UUID；`ownInvocationId` 要等 stream `invocation_created` 到达后才捕获；hold_ball route 有 callback-auth invocationId 但 trace 侧无桥；A2A route guard 在 generator 内部（非 HTTP 通道）。→ **精确三元组 join 当前不可得，"小改"表述作废**。
+
+两档 correlation：
+- **Week 1 默认（半精确）**：`threadId + catId + timestamp window + guardId`，事件带 `correlationConfidence: 'window'`——T2a 差分在窗口置信度上就能算（版本前后违规率对比不需要逐 turn 精确归属）
+- **后续增强（精确）**：trace summary 持久化 invocationId 或建 `traceTurnId ↔ invocationId` bridge；guard event 统一带可用 invocationId；confidence 升 `'exact'`。作为独立小工作项，不阻塞 Week 1
+
+段侧粒度（**2026-07-09 合入后重验**）：#1075 已合入 main（`ebffcd8e5`），46 hook.yaml 就位，**段口径正式切换为 hook manifest（46）**。但重验证实 codex 预判：合入版 route-serial 仍 `drainCapturedTraces()`（L698/804/893），持久化仍走 v0 `collectTrace`（L879）——**逐 hook TraceEvent 已生成但被丢弃**。粒度从 aggregate 升逐段还差一个「trace 持久化桥」工作项（把 drain 掉的 TraceEvent[] 接入持久化），归属随 PR3 一并与 F237 线对齐（KD-13）。Week 1 设计不受影响（窗口 correlation + aggregate 本就够 T2a）。
+
+### 2.1b GuardRejectionEventLog（v0.1 重写，codex P1-3）
+
+**接口先于存储**：`append(event)` + `queryWindow({since, until, guardId?, threadId?, catId?})`。归因阈值和 weekly eval 都是窗口扫描——F254 的 per-invocation LIST 形态**不可发现**（不知道扫哪些 invocation），不照抄。
+
+存储：global ZSET by timestamp（index）+ detail key；raw payload 不落盘（只存 normalized 字段 + anchor 引用）；**fail-open**——观测层故障绝不阻塞业务调用。
+
+事件 union 按来源分型（codex P1-4，"4 处各加几行"表述作废）：
+
+| 事件类型 | 实例 | emit 位置 | 测试方式 | Week 1 |
+|---------|------|----------|---------|--------|
+| `http_schema_reject` | waitSourceRef 400 | HTTP route handler | route 单测 | 后续 |
+| `http_policy_reject` | gate-keeping 400 | HTTP route handler | route 单测 | 后续 |
+| `http_rate_limit` | hold_ball 429 | HTTP route handler | route 单测 | ✅ |
+| `publish_policy_reject` | publish_verdict 403 | eval-hub route（HandlerError → reply.status） | route 单测 | 后续 |
+| `route_decision_skip` | A2A guard skip | route-serial generator 内 `continue` | generator 集成测试 | 后续 |
+| `route_decision_block` | block_pingpong | generator yield system_info | generator 集成测试 | ✅ |
+
+Week 1 Line B 只上 2 类（`http_rate_limit` + `route_decision_block`）：一个 HTTP 面一个 generator 面，把两种工程面的 emit 通道都走通，其余 4 类扩面是机械推广。route guard 类**单独估算工作量**，不按"微改"计。
+
+第三 ground truth 源：eval:sop 的 violation 产出（已有，KD-8 边界维持——SOP 段的行为证据委托 eval:sop，不重建）。
+
+### 2.2 留存
+
+热层 7d（Redis，与既有 log 一致）→ weekly eval 拉取时聚合快照进 verdict bundle（git，永久）——借 F237 summary/detail 双层思路，解决 30d 窗口问题且零新存储系统。
+
+## 3. 评估面：三层判定（按成本升序）
+
+| 层 | 判定 | 需要什么 | 何时可跑 |
+|----|------|---------|---------|
+| **T1 静态** | ①跨层冗余：O2 段断言已被 O1 结构承载（星星罐子型）②段间矛盾：同 context 反向断言（规则不 compose 型）③语义撞词：拉闸词与技术名词冲突（脚手架型） | 只需段内容 + 结构 guard 清单 | **day-0**（全量段一轮体检，口径见 §6） |
+| **T2a 差分·自动** | guard ground truth：段 fired 且对应违规仍发生 → low-evidence；版本切换前后违规率对比（窗口置信度即可算） | correlation 双侧事件（§2.1） | Line B 落地后 |
+| **T2b 差分·半自动** | provenance / truth-source drift 类：ground truth 由 eval/review 标注（无结构 guard 可依） | 标注流程 | 与 T2a 同期，吞吐更低 |
+| **T3 缺段** | 同类纠正/摩擦反复出现但无段承载 | Week 1 用 friction rollup 现有产物半自动初筛；正式第五 source adapter（含 FrictionChannel union/composition/tests 扩展）**放 Phase B 不压 Week 1** | day-0 可半自动 |
+
+**核心指标 = 行为差分，不是注入率**（公理 A1，三猫三模型实证）。
+
+### verdict 词表（段专用 v0）
+
+`alive` / `redundant-candidate(cross-layer | duplicate)` / `conflict` / `false-positive-noise` / `low-evidence` / `missing-segment` / `superseded`（LL-071 型：被结构替代，光荣退役）/ `unmeasurable(+observabilityDeadline)`。通用锅账词表（spec 既有）在泛化阶段合并。
+
+## 4. 迭代面（v0.2 重写——override-first，co-creator 2026-07-08 12:32 迭代模型）
+
+> **v0.1 的"段文本迭代走 git PR"通道被否，理由成立**：①改了不知道有没有效，未验证的改动不能直接固化为基线；②可能只需 rollback / 启禁用，PR 通道太重且慢；③安装包用户无法改随包分发文件，该通道只对源码开发者存在。**试验在 override 层，基线沉淀要证据。**
+
+**迭代生命周期**（段/skill 类资产统一模型）：
+
+```
+tracing（持续，永不撤）
+  → eval 发现问题（candidate 报告）
+  → override 层改动（禁用 / 内容调整——不动 base 文件）
+  → 效果确认（contentHash/override 版本差分，下一 eval 周期自动产出）
+  → 继续迭代（可随时 rollback = 撤销 override）
+  → eval 进入相对稳定波动 → 停止改进（tracing + eval 保留）
+  → 迭代记录 + 证据链在手
+  → 基线沉淀：源码环境 → 上游 PR 入库；安装包用户 → 主动触发提 issue（附迭代证据）
+```
+
+**三类对象三种通道**（co-creator 分类）：
+
+| 对象 | 通道 | 迭代层前提 |
+|------|------|-----------|
+| 代码功能问题 | 收集 → 归因 → issue（蓝色通道）；源码环境可改，安装包用户提 issue 即止 | 无（现有流程） |
+| 段（prompt hooks） | override 迭代（启禁用/调整）→ eval 稳定 → 带证据入库 | **`HookOverrideStore`（#1075 PR3）** |
+| skill | 同段模型（overlay：base 随包不可变 + overlay 迭代 + 版本自见），deferred | 段走通后复用同基建 |
+
+**operator gate 位置**：O2→O1 结构升级与段退役仍走 approve（硬边界不变）；override 试验本身低风险可逆（随时撤销），其审批粒度（逐个 approve vs 批量授权试验窗口）→ Design Gate 补充对齐。
+
+**依赖关系修正（取代 v0.1 表述）**：
+- **观测 + 评估**（线 A / 线 B / weekly eval / candidate 报告）：不依赖 #1075——tracing 和 eval 是永久基建，先行建设，这部分本来就"要保留"
+- **迭代环（override 试验）：以 #1075 + PR3 `HookOverrideStore` 为前提**——"要基于 1075"的准确含义。PR3 目前尚未存在（F237 Phase 2 的 deferred scope），需与 F237 线对齐：PR3 优先级提升 or F257 承接实现
+- override 层就绪前：评估只产 candidate 报告（只读），**不动任何段**
+
+**账本伴生**：每次 override 试验与基线沉淀登记 ledger YAML（spec 既有 schema），registry 从真实迭代里长出来（KD-10 不变）。
+
+## 5. 首批评估对象（有 ground truth 的段先评）
+
+1. **路由/传球出口段** — ground truth: route guard 拒绝（GuardRejectionEventLog 首批覆盖）
+2. **provenance/source 段** — ground truth: SC-002/#1075 型事件（v0 承认半自动：review 发现人工标注）
+3. **truth-source 写回段** — ground truth: seed cases + spec diff 检查
+
+phase-boundary drift 检查卡（砚砚最想要，一卡拦 SC-002/003/004）：**第二批**——主线闭环走通后做，实现是 lint/checklist 级，其判据已被 seed cases 固化，不会丢。
+
+## 6. 开工顺序（"怎么继续"）
+
+**Week 1 双线并行**：
+- **线 A（第一个可交付，零新基建）**：T1 静态体检 + T3 缺段初筛 → **第一份 candidate 报告**给 operator。**段口径 source-of-truth（codex P2-4）**：pre-#1075 按 current template registry（**50 个 template id，含 D7/D15 变体**；how_counted: `TEMPLATE_FILES` 常量计数 @ 当前分支）；#1075 合入后切 hook manifest 口径（46 hook.yaml @ PR diff）。两口径差异在报告中显式声明
+- **线 B（基建）**：GuardRejectionEventLog（queryWindow 接口 + ZSET 索引）+ **2 类事件 emit**（`http_rate_limit` + `route_decision_block`，一 HTTP 面一 generator 面）→ codex review。精确 correlation bridge 为独立后续项
+
+**Week 2+**：`eval:harness-ledger` 域注册（selector `{scope: 'prompt-segments'}`，weekly）→ T2a 差分进周期 → candidate 报告持续产出 → 其余 4 类事件扩面 → drift 检查卡。
+
+**迭代环开动条件（v0.2）**：override 层就绪（#1075 + PR3 `HookOverrideStore`）。就绪前评估只读不动段；PR3 的归属与优先级与 F237 线对齐，作为开工后并行协调事项，不阻塞观测评估建设。
+
+**v0.4 升级（2026-07-09 co-creator 拍板）**：`HookOverrideStore` 从"前提"升为**必做项、优先级提前**——"否则没法做 auto harness"；直改段原文除未验证固化外还有两个问题：与上游数据不一致 + 同步代码冲突。
+
+**验收路径（co-creator 定调，取代泛化时间线）**：
+```
+改动 → 合入本地集成分支 → co-creator 真实开发使用（dogfood）
+→ 自动发现问题 + 优化通知 + 审批 → 审批后迭代
+→ 至少 2~3 轮自动优化迭代 → 实证「自动生效 + 优化有效」
+→ 带自动迭代证据链往上游提 PR（证明可推广）
+→ 而后才扩展其他 harness unit（基础功能 / MCP / skill）
+```
+段是第一个 harness unit；上游 PR 的说服力 = 我们自己家 2-3 轮迭代的证据链。触发入口形态开放（skill 只是候选之一，不锁定）。
+
+**F237 scope 综合（进行中）**：F237 下阶段 = 段的完整评估处理（不止 Console UI）；F257 向其输送审计证据 / A1 公理 / 判定设计 / 收敛模型，分工沟通中（见工作 thread）。
+
+**里程碑判据**（对齐 AC-A0 精神）：≥1 个段完成完整五环（评估 candidate → approve → 修补 → 版本差分显示违规下降 or 证伪）。走不通 = 设计证伪，停下重议，沉没成本 = 一个 event log + 一份静态报告。
+
+## 7. 改动范围
+
+| 改动 | 位置 | 量级 |
+|------|------|------|
+| GuardRejectionEventLog | packages/api 新文件（queryWindow + ZSET 索引，**非** F254 LIST 形态） | ~200 行 + 测试 |
+| Week 1 emit ×2 | `http_rate_limit`（HTTP route，route 单测）+ `route_decision_block`（generator，集成测试） | 两种工程面各一，**route guard 类单独估算** |
+| 其余 4 类 emit 扩面 | 见 §2.1b 分型表 | Week 2+，机械推广 |
+| 精确 correlation bridge | trace summary 持久化 invocationId 或 traceTurnId↔invocationId 桥 | 独立后续项，不阻塞 Week 1 |
+| eval 域 selector | eval:harness-ledger 域配置加 `{scope: 'prompt-segments'}`（不新增域名） | 配置 |
+| T1 静态体检 | 脚本 or eval cat 执行（不进运行时） | 只读 |
+| **不碰** | 段内容本身（评估只读）、eval 机制、运行时主链路行为、skill | — |
+
+## 8. 体系自身防腐
+
+- seed-cases 持续记录本体系开发偏差（自举条款不变）
+- sunset signal：`eval:harness-ledger` 的 prompt-segments scope 连续 4 周期无 actionable verdict → scope 降频/并入 eval:friction（防第 131 口锅）
+- 所有报告数字带 `how_counted`（SC-002 纪律）
+
+## 9. 开发前五问（2026-07-08 co-creator gate，v0.3）
+
+> "开发之前，你需要先好好想想：怎么 tracing / 怎么触发 / 怎么 eval / eval 什么 / 怎么改（启禁用段还是修改段内容）"。架构关系定调：#1075 是基础层，F257 是其上的 auto harness 层。
+
+### 10.1 怎么 tracing —— 双侧最小充分集（v0.4 修正：关联模型）
+
+> **2026-07-09 co-creator 修正**：console manifest API 只是静态清单/预览面，**不是评估数据源**——"直接根据 console 接口看到的来评估脱离实际"。评估需要**运行时关联数据**：
+> - **turn 维度**：该 turn 注入的段列表 × 实际用户输入 × 实际结果（锚点引用 events.jsonl，不复制原文）
+> - **session 维度**：session 级注入 + turn 索引聚合
+>
+> 这解锁一个此前缺失的评估维度——**注入频率/stage 优化**（正好映射 hook 的 S/D stage 结构）：
+> - 某段每 turn 注入 → 数据显示 session 一次即可 → **降频**（省 token）
+> - 某段 session 注入 → 多轮后注意力衰减（行为违规随 turn 深度上升）→ **升频到 turn**
+>
+> verdict 词表增补：`stage-adjust-candidate(session→turn | turn→session)`。
+
+段的价值只能用行为差分证明（公理 A1），所以 tracing 必须**双侧**：
+- **供给侧**（段进了没有）：hookId / 版本（base contentHash + **override 版本**）/ fired|skipped + skip 原因 / token 长度。来源：#1029 现有 + #1075 逐段增强 + override 层版本标注（PR3 就绪后）
+- **效果侧**（行为变了没有）：结构化信号 = GuardRejectionEventLog（线 B）；非结构化信号 = eval/review 标注（T2b）
+- 最小充分集 = `(段, 版本, 注入与否) × (违规类型, 时间)` 可按窗口 correlation join（§2.1）
+
+### 10.2 怎么触发 —— 三档事件驱动（零轮询不变）
+
+| 档 | 触发事件 | 动作 |
+|----|---------|------|
+| **变更驱动**（最密集） | 某段 override 变更（启禁用/调整）→ 该段进入观察期 | 观察期满（累积 N session 或 7d，取先到）自动触发**该段**差分评估 |
+| **阈值驱动**（即时） | 同 guard 拒绝达阈值（per-guard 配置，默认 3/7d） | 即时归因评估**关联段**，不等周期 |
+| **周期兜底**（全量） | weekly eval cron（已有基建） | 全段扫描，抓慢性病（dormant / 冗余 / 缺段） |
+
+核心原则：**评估密度跟着变更走**——改了才密集评估，没改的段只被周期兜底扫到，不平摊评估资源。
+
+### 10.3 eval 什么 —— 段的净价值 = 行为改善 − 注意力成本
+
+每段五个指标：①成本 = 注入频率 × token 长度（全段 day-0 可算）②效果 = 关联违规率（有 guard ground truth 自动 / 无则 T2b 标注）③**差分 = override 变更前后关联违规率变化**（"改了有没有效"的直接答案）④关系 = 跨层冗余/矛盾/撞词（T1）⑤缺口 = 无段承载的重复纠正（T3）。
+
+### 10.4 怎么 eval —— 三层判定 + 停止条件
+
+T1 脚本判定（确定性，CI 可跑）/ T2a 窗口差分（统计——**初期样本量小，报告标注"方向性证据"，不冒充统计显著**）/ T2b predicate 抽样（借 eval:sop 的 predicate 形态给段 assertion 写判定）。汇总进 `eval:harness-ledger` weekly verdict。
+**停止条件**（co-creator 模型）：段指标进入相对稳定波动 → 停止主动改进 → 转低频监控（**tracing 与 eval 永久保留**，不随改进停止而撤）。
+
+### 10.5 怎么改 —— 消融优先，内容其次，条件第三
+
+| 优先级 | 改法 | 适用 | 为什么 |
+|--------|------|------|--------|
+| 1 | **启禁用（消融试验）** | 疑似冗余 / low-evidence 段 | **单变量因果验证最干净**：禁用只改"存在与否"一个变量。违规率升 = 段有用，一键恢复（撤 override）；无变化 = retire 的证据基础（base 删除仍走 operator approve）。禁用是 retire 的前置实验 |
+| 2 | **内容调整** | 确认有用但效果差的段（fired 了违规照发——段在场没起作用） | 变量多（措辞/长度/结构），验证靠 override 版本差分；初期只做**单变量修改**（如高违规段的措辞强化），不重写 |
+| 3 | **fire 条件调整** | 全场景注入但只在部分场景相关的段 | 改 resolver 注入条件不改内容——降低无关场景的注意力稀释（#1075 resolver 纯函数天然支持 override） |
+
+顺序逻辑：**先禁用验证存在价值 → 再内容优化有价值的段 → 后条件收窄注入面**。三种改法全部发生在 override 层（KD-12），全部可即时 rollback。
+
+### 9.6 执行模型四答（2026-07-09 co-creator 追问）
+
+**Q1 tracing 数据放哪**：三层——热层 Redis（注入 trace：InjectionTraceStore 族，summary 永久 + detail 7d；guard/反馈事件：GuardRejectionEventLog ZSET 时间索引，7d）→ 冷层 git（weekly eval 拉取聚合快照进 `docs/harness-feedback/bundles/`，永久可复算）→ 关联锚点引用 events.jsonl（不复制输入输出原文）。
+
+**Q2 eval 谁做/哪做/纠正怎么进评估**：执行者 = `eval:harness-ledger` 域的 **eval cat**（F192 现成机制：域配 evalCat + system thread，cron/触发唤醒）——**不是开发 thread 里的猫**。链路：thread A 纠正发生 → 被纠正猫上报结构化反馈事件（关联段猜测 + threadId + ts）→ 事件**积累不立即评估**（单次纠正样本不足）→ 阈值命中（同段关联事件攒够）调度该段即时评估 / weekly 兜底全扫。**评估按段不按 thread**：eval cat 拉全局段数据，thread A/B 的事件天然汇入同一段的时间线。
+
+**Q3 指标规则放哪/和段一起管理吗/怎么迭代/首版**：
+- schema（类型）：`packages/shared/src/types/harness-judgment.ts`（纯契约）
+- **段判定实例：`assets/prompt-hooks/<hook>/judgment.yaml`——与段同域共管**（改段时判定就在旁边）
+- 评估引擎：`packages/api/src/infrastructure/harness-eval/harness-ledger/`（与 sop evaluator 同层）
+- 全局参数（ε/K/阈值默认）：eval 域 YAML
+- 迭代：指标版本化，verdict 带指标版本；**operator suppress 率高 = 指标不合适信号** → 修订队列；指标改动走 git PR（可在历史数据上回放对比验证）
+- 首版：手写——首批 3 类段（路由/provenance/写回）判定实例源自 30 天审计 + 三猫体感 + seed cases；T1 规则即 opus 三增量；其余段先只有成本指标，效果指标标 unmeasurable 渐进补
+
+**Q4 审批-修改链 + 拒绝反馈环 + 允许静默（三条新决策）**：
+- 通知 → 你确认 → **自动调 override 接口** = 代码行为，**端到端一次做完、无 followup 无过渡态**（2026-07-09 co-creator 纠正："人工执行过渡"撤销）——审批执行器是正式 scope 的一部分，与 PR3 override API 在 Week 2 联调期同步接通；**dogfood 进入条件 = 全链路（tracing→触发→eval→verdict→审批→自动执行→差分）代码化跑通**，dogfood 阶段 operator 只做一个动作：点确认/拒绝
+- **拒绝也是数据**：suppress/reject 落结构化事件 `{verdictId, segmentId, rejectReason, ts}` 进同一时间线；下一轮评估该段时，**历史被拒方案 + 拒因是评估器输入**——不重复提被否建议，或针对拒因给新方案（评估器有记忆）
+- **允许不产生通知（防过拟合铁则）**：合法 verdict 含 `insufficient-data`（数据不足静默继续积累）与 `no-action-needed`（段无实质影响跳过）——**不进审批通知，静默记录**。不为评估而评估。
+
+## 10. 与理想态的差距（诚实声明）
+
+- 五环全自动是 north star；v0 的归因半自动（阈值开 task，归因本身靠猫）、修补全人工（approve 通道）
+- Week 1 correlation 是窗口置信度（`correlationConfidence: 'window'`），精确 join 是后续增强；T2a 差分在窗口置信度上成立
+- 段粒度 aggregate → 逐段依赖 #1075 实际合入形态，**以合入后 AC/code 为准重验，不预设**
+- T2b（provenance / truth-source drift）ground truth 半自动（eval/review 标注）
+- 时间尺度：修补验证以 weekly 周期为单位，闭环证明 ≥2-3 周

+# T1 静态体检 — 工作底稿（Week 1 线 A）
+
+> 状态：**in-progress**（2026-07-09 开工；基线 `ebffcd8e5` = post-#1075）
+> 交付物：candidate 报告（跨层冗余 / 段间矛盾 / 语义撞词 + T3 缺段初筛），全部数字带 how_counted
+> AC 锚点：AC-A0 ①（spec §Week 1 线 A，L141）
+
+## 口径声明（SC-002 条款）
+
+- 本底稿一切计数在 `feat/f257-harness-ledger` worktree、基线 `ebffcd8e5`（#1075 已合入 = **post-#1075 段口径**）下由命令导出，命令原样记录
+- pre-#1075 口径（启动包"130+ 锅"：86 工具/43 GOTCHA/31 强命令/8 fail-closed）已被 OQ-5 回查定性为"四种口径混排、不可复算"（msg `0001783342151331`）——本报告**不继承任何旧数字**，全部重新 derive
+
+## L0 inventory（post-#1075，2026-07-09）
+
+| 层 | 计数 | how_counted（可复算命令，worktree root） | 备注 |
+|---|---|---|---|
+| 段层 hooks | **46** | `find assets/prompt-hooks -name hook.yaml -not -path "*/node_modules/*" \| wc -l` | #1075 的段口径；stage 前缀分布：s×13 / d×21 / l×7 / r×2 / b1 / c1 / n1 |
+| skill 层条目 | 51（原始，含非 skill 项） | `ls cat-cafe-skills/ \| wc -l` | 待精化口径：目录含 SKILL.md 才算 skill |
+| skill 含 GOTCHA | 9 个 SKILL.md | `rg -l "GOTCHA" cat-cafe-skills -g "SKILL.md" \| wc -l` | 与启动包"21 GOTCHA"不同——那可能是 occurrence 口径，待复核后显式标注两种口径 |
+| memory 层 | 22 files（仅 Fable 本猫） | `ls ~/.claude/projects/-Users-lang-workspace-github-clowder-ai/memory/*.md \| wc -l` | per-cat 各异；全量口径需按 catId 枚举各家目录 |
+| MCP 层 | 待 derive | 源已定位：`packages/mcp-server/src/tools` + `packages/api/src/mcp` | 下一步：按 tool 定义文件数 + description 内 GOTCHA/强命令模式分别计数 |
+
+## 段 schema 实测（→ judgment schema v1 的输入）
+
+46 个 hook.yaml 字段齐整：`id / name / stage / order / version / enabled / template / resolver / inputs / disableable / safetyTier / transparencyTier / governanceTier / userExplanation`（样本：`s1-身份声明/hook.yaml`）。
+
+- **T1 直接可用的轴**：stage（注入时机）、disableable（可否 override）、governanceTier（治理级）
+- **缺失字段（T1 论证目标）**：
+  1. `audience`（受众边界）——A3 公理候选的 schema 落点；当前所有段隐式全员广播
+  2. `assertion`（该段应产生什么可检验的行为差分）——A1 公理的 schema 落点；无 assertion 的段无法进 eval
+
+## Day-0 candidates（活体收集，T1-C 编号；n = 独立证据数）
+
+| # | 类型 | 内容 | 证据锚点 | n |

+> 注：T1-C* 是 candidate 不是结论；进 judgment schema v1 后按五环走（candidate → operator approve → 修补 → 行为差分 → 固化/证伪）。
+
+## 扫描方法（下一步执行序）
+
+1. **冗余扫描**：46 段 template 内容 ↔ shared-rules/skill 重叠段落——先机械（关键短语族 rg 匹配矩阵），再人工判定"重复注入是否产生边际价值"（codex 体感：同 assertion 多段注入而 guard 仍触发 = 文本边际价值低）
+2. **矛盾扫描**：同主题反向指令对。候选主题：简短至上 vs 愿景驱动（客观性 carry-over 已知冲突）、hold vs @ 出口、自决 vs 升级边界（opus 疼点③）
+3. **撞词扫描**：magic word 与技术术语多义（已知案例：「脚手架」拉闸词 vs 技术名词，gemini/opus 双报）
+4. 每 candidate 输出：segmentId(s) + 判定 + 证据行 + 建议动作（merge / retire / rewrite / keep / add-guard）
+
+## T1 扫描结果（2026-07-10，opus 实施）
+
+> 方法：46 hook template 全量内容读取 + 关键短语交叉匹配（`grep -rl` 跨 `assets/prompt-templates/`）+ 语义对照人工判定。how_counted: `grep -rl "phrase" assets/prompt-templates/ | sed ...`
+
+### ① 跨层冗余（同一 assertion 多段注入）
+
+| # | 标题 | 段对 | 重叠描述 | 建议动作 | 待 T2a 验证 |
+|---|------|------|---------|---------|-----------|
+| T1-F1 | **决策树双注入** | L3(session-init,28L) ↔ D21(per-turn,8L) | 同一"传球三选一"决策树——L3 完整版，D21 压缩版。核心 assertion 相同："每条 A2A 串行回合必选其一，缺 = 消息不完整"。D21 是 L3 内容的~71%语义覆盖 | **redundant-candidate(cross-layer)**：保留一个（L3 或 D21），T2a 差分验证 per-turn 重复注入是否带来边际行为改善 | D21 去除前后 routing 违规率对比 |
+| T1-F2 | **@ 路由格式三注入** | D8 + L3 + S4 | 三段三种措辞教同一 assertion："@句柄必须在行首，句中无效"。D8："行首 @句柄，句中无效"；L3："行首独立一行…不路由——球权掉地上"；S4："行中无效…非行首位置的 @ 都不路由，球权掉地上" | **redundant-candidate(duplicate)**：同 assertion 三表述，per codex 体感"同 assertion 多段注入但 guard 仍触发 = 文本边际价值低" | 保留 1 段后 @ 格式违规率 |
+| T1-F3 | **"非孤立"身份双框架** | L1 ↔ L7（均 session-init） | L1："你不是一个孤立的工具"；L7："你是有队友…不是孤立的执行单元"——同一 identity framing 两种表达。但 L1 附加 parallel world 意识，L7 附加代码哲学 | 部分冗余——开头 identity 声明合并，各自专有内容保留 | 低优先 |
+| T1-F4 | **hold_ball 四处教学** | D8 + D21 + L3 + L5 | 4 段含 hold_ball 使用说明。核心重叠：D21 与 L3 的调用语法几乎逐字相同（`cat_cafe_hold_ball({ wakeAfterMs, waitSourceRef: ... })`）。D8 教概念，L5 是 tool index | D21↔L3 是 T1-F1 的子集；D8/L5 各有独立用途 | 归入 T1-F1 |
+| T1-F5 | **@co-creator 升级路径四处教** | D21 + L1 + L3 + L7 | 4 段教何时 @co-creator。L3 最完整（硬条件列表），D21 压缩版，L1/L7 仅提及 | 同 T1-F1——L3↔D21 是主重叠 | 归入 T1-F1 |
+
+**P0 观察**：T1-F1/F2/F4/F5 指向同一个根问题——**L3 和 D21 大面积语义重叠**，其中 L3 是 session-init 完整版，D21 是 per-turn 压缩版。如果 T2a 差分证明 per-turn 重注入无边际行为改善，D21 可退役（最大单点 token 节约）。
+
+### ② 段间矛盾
+
+| # | 标题 | 段对 | 分析 |
+|---|------|------|------|
+| T1-F6 | 无显式静态矛盾 | — | 46 模板内容全量读取，未发现同主题反向指令对。已知张力"simplest first vs quality-driven"在 §2 carry-over 层已处理（删除 Anthropic 默认糊弄指令）。passthrough 模板（S9/S10）注入运行时动态内容——其与静态模板的矛盾**无法在 T1 层检测**，需 T2b 运行时 trace 对照 |
+
+### ③ 语义撞词
+
+| # | 标题 | 内容 | 分析 |
+|---|------|------|------|
+| T1-F7 | magic words 不在 hook 管辖范围 | 10 个 magic word 全部存在于 `shared-rules.md`，经 S9 passthrough（`{{GOVERNANCE_DIGEST}}`）注入。hook.yaml 46 个 manifest 均不含 magic word 文本 | 撞词问题（如「脚手架」拉闸词 vs 技术名词，opus/gemini 双报）存在但归属 shared-rules 治理，不在 hook 层可控范围。hook 层无法静态检测此类冲突 |
+
+### 结构性发现（T1 视角的 schema 缺口）
+
+| # | 标题 | 内容 |
+|---|------|------|
+| T1-S1 | **passthrough 模板阻断静态分析** | S9（`{{GOVERNANCE_DIGEST}}`）、S10（`{{PACK_GUARDRAILS_BLOCK}}`）注入运行时 resolve 的动态内容。shared-rules 的全量文本（Magic Words / 决策漏斗 / hotfix 纪律 / per-family 治理等）经 S9 passthrough 进入 prompt，可能与 L3/D21/D8 等模板存在 **静态不可检测的冗余**。T1 完整覆盖需要 resolver 仿真或运行时 trace 快照对照 |
+| T1-S2 | **`audience` 字段缺失** | 46 hook.yaml 无 `audience` 字段。所有段隐式全员广播。A3 公理（"段没有受众边界 = 负资产"）无法在 hook schema 层检验。gemini 体感实证：SEO/前端实现规范注入给非代码猫 = 负价值 token |
+| T1-S3 | **`assertion` 字段缺失** | 46 hook.yaml 无 `assertion` 字段。无法表达"该段应产生什么可检验行为差分"。A1 公理（"核心指标是行为差分不是注入率"）的 schema 落点缺失——没有 assertion 的段无法进 T2a eval |
+| T1-S4 | **per-breed 工作流分化无跨 breed 一致性检查** | S6 有 4 breed 变体。maine-coon 独有"长任务纪律"+"fallback 层数检测"；siamese 独有"截图产出证据"；golden-chinchilla 独有"OMOC Sisyphus"+"question 工具已 deny"。变体间共性部分（出口一问 / Rule 0 / MG provenance override）手动重复——缺 shared base + override 结构 |
+
+### 更新后 candidate 汇总（Day-0 + T1 扫描）
+
+| # | 类型 | verdict 建议 | 下一步 |
+|---|------|------------|--------|
+| T1-C1 | 缺段 | missing-segment | GuardRejectionEventLog（Phase A Line B） |
+| T1-C2 | 缺段 | missing-segment | F 号分配守卫（F258 已闭环，不再 active） |
+| T1-C3 | 缺段 | missing-segment | 角色硬限路由守卫（T3 候选，Week 1 不做） |
+| T1-C4 | 受众错配 | conflict（audience） | audience 字段 + 受众匹配逻辑（T1-S2） |
+| T1-C5 | 缺段 | missing-segment | 签名校验守卫（T3 候选） |
+| **T1-F1** | **跨层冗余** | **redundant-candidate(cross-layer)** | **T2a 差分：D21 去除后 routing 违规率** |
+| **T1-F2** | **重复注入** | **redundant-candidate(duplicate)** | **T2a 差分：@ 格式 assertion 减至 1 段后违规率** |
+| T1-F3 | 部分冗余 | alive（各有专有内容） | 低优先，可选合并 identity 声明 |

+    候选，直接升 O1 结构 guard（LI-005 触发器绑定 / dispatch pending-dependency 卡）。
+```
+
+**结构性设计输入（operator 01:46 元问题的答案）**：体系不会因为存在而被走——**只有当它是最短路径时才会被走**。当前「直接改文档」比「登记 candidate」快一个数量级，压力下猫必选最短路径（本例实证）。体系要赢的两条路：①入账工具化到一步（MCP 工具 30 秒登记 candidate+trial）②无账变更被结构拦截（prompt/规则文件 pre-commit 查 ledger 引用，无引用拒绝）。两者进 F257 工程队列——这是「机制 scope 未覆盖时纳入机制」的机制本身。
+
+## 下一步（五环推进路径）
+
+1. **验证环**：LI-001 已进 `verifying`；以 2026-07-15 为 treatment 起点，窗口 ≥5 天后记录 no-response / 误重试复发差分，不提前判 improved。
+2. **结构修补环**：LI-005 durable A2A trigger/ack 状态机为下一实现项；LI-002 O1 runtime facts、LI-003 operator-correction 事件、LI-004 pre-commit guard 继续排队。
+3. **首个完整五环**：从已有 candidate 中选择可安全 override 的真实段，完成 candidate → 决策 → PatchTrial → ≥5 天差分 → solidify/rollback/retire，兑现 AC-A0/AC-E1，而不是用“代码已合入”替代闭环。
+4. **体系入口**：把 candidate/trial 登记压缩为一步工具，并为规则/段变更加 ledger reference gate；体系只有成为最短路径才会被持续使用。

+- Stage ③ local peer review: local reviewer completes first-pass review.
+- When a cloud finding arrives (cloud / GitHub review), nextGateOwner = cloud.
+- After cloud findings are addressed, fixes must only re-trigger cloud review.
+- Do not @ local旧reviewer for cloud-finding follow-ups.

+# F257 Objective Evaluation Redesign Implementation Plan
+
+**Feature:** F257 — `docs/features/F257-harness-ledger.md`
+**Goal:** 把 Harness Ledger 从“按时间窗给段分摊 guard 事件并显示伪违规率”重构为“invocation 全程 tracing、统一 trace annotation、Objective 自有评估规则、阈值/周期异步评估、append-only 指标结果”的可解释闭环。
+**Acceptance Criteria:** AC-1 tracing 从 invocation 已有起点持续采集并在 terminal 时以 `invocationId/inputMessageId/outputMessageId/traceTurnId` 精确闭合；AC-2 MCP 只写 pending marker，不直接制造评估结论；AC-3 MCP、结构化规则、周期语义分析写入同一种 append-only annotation；AC-4 count 指标无需分母，去重反例 episode 达阈值即可触发；AC-5 rate/semantic/replay 指标各自显式声明输入和规则；AC-6 Objective 只保存静态定义与段挂靠，不引入 Objective 状态机；AC-7 scheduler 仅依据规则 readiness/阈值/时间窗调度，LLM 语义分析完全异步且不阻塞主流程；AC-8 evaluation snapshot 可重放，MetricResult append-only 回写；AC-9 旧 `SegmentJudgment` 时间窗归因与 `SegmentJudgmentCache` 不再作为评估或 Console 真相源；AC-10 23 个 Objective 与 46 个段/条款 100% 有唯一可寻址挂靠；AC-11 Eval Console 展示归属、评估模型、指标、时间和窗口，Tracing 展示真实 episode 回放；AC-12 旧的不合适派生评估数据不迁移、不兼容、不参与新结果，且不删除原始 tracing、message、thread 或其他用户数据。
+**Architecture cell:** harness-eval
+**Map delta:** update required
+**Map delta why:** `harness-eval` 的当前 ownership cell 仍把 `SegmentJudgment`/时间窗 join/`SegmentJudgmentCache` 列为核心产物；本次要改为 TraceEpisode/TraceAnnotation/EvaluationSnapshot/MetricResult，并明确 tracing 与 eval 的边界。
+**Architecture:** 现有 HookPipeline tracing 继续在 invocation 前半段采集 prompt exposure；terminal seam 只追加不可变的 episode closure。三类判定来源统一写 trace annotation sidecar，EvaluationIndexer 只消费 annotations 并按 manifest 纯投影到 Objective/Metric；scheduler 冻结 snapshot 后选择 code/LLM/replay evaluator，最终写 append-only MetricResult。主请求路径不运行 LLM，也不等待 eval。
+**Tech Stack:** TypeScript, Redis/ioredis, Node test runner, YAML registry/manifest, React/Next.js Console
+**前端验证:** Yes — reviewer 必须用 Browser/Playwright 实测 Eval 指标卡、Tracing 回放剧场和段编辑器。
+
+---
+
+## 0. Straight-line finish line
+
+终态 B：任何 invocation 都能形成一个可回放 TraceEpisode；如果 MCP 或结构化规则已识别归属，terminal 后直接得到统一 annotation；未归属 episode 由后台语义 sweep 分类；每个 Objective 的 manifest 决定指标输入、规则与触发条件；满足 count 阈值或窗口 readiness 后自动生成可重放 snapshot 并写入 MetricResult。
+
+不做：
+
+- 不在主回复路径调用 LLM。
+- 不让 tracing 决定 Objective、Metric 或 verdict。
+- 不把所有指标强制压成 `numerator / denominator`。
+- 不保留旧 objective id、旧 SegmentJudgment 或旧派生数据的兼容层。
+- 不删除/flush Redis、SQLite、thread、message、raw trace 等持久数据。
+- 不把 verdict 重新写入 Git/PR；继续使用 local artifact store。
+
+## 1. Terminal schema
+
+```ts
+type MetricKind = 'counter' | 'rate' | 'semantic' | 'replay';
+type AnnotationSource = 'mcp-marker' | 'structured-rule' | 'semantic-sweep';
+
+interface TraceEpisodeRef {
+  traceTurnId: string;
+  invocationId: string;
+  threadId: string;
+  catId: string;
+  inputMessageId: string;
+  outputMessageId: string;
+}
+
+interface TraceTerminalExtension extends TraceEpisodeRef {
+  terminalAt: number;
+  terminalKind: 'completed' | 'failed' | 'cancelled';
+  outputText?: string;
+  toolCalls: Array<{ toolName: string; callId?: string; outcome: 'ok' | 'error' }>;
+}
+
+interface PendingTraceMarker {
+  markerId: string;
+  invocationId: string;
+  ownerUserId: string;
+  subjectCatId: string;
+  objectiveId: string;
+  metricId: string;
+  unitRefs: Array<{ unitType: 'segment'; unitId: string; clauseId?: string }>;
+  polarity: 'counterexample' | 'positive' | 'candidate';
+  note?: string;
+  createdAt: number;
+}
+
+interface TraceAnnotation {
+  annotationId: string;
+  episodeRef: TraceEpisodeRef;
+  source: AnnotationSource;
+  ruleId: string;
+  objectiveId: string;
+  metricId: string;
+  unitRefs: Array<{ unitType: 'segment'; unitId: string; clauseId?: string }>;
+  polarity: 'counterexample' | 'positive' | 'irrelevant' | 'unscorable';
+  confidence: number;
+  incidentKey: string;
+  evidenceRefs: string[];
+  createdAt: number;
+}
+
+interface MetricDefinition {
+  id: string;
+  kind: MetricKind;
+  evaluator: { kind: 'code' | 'llm' | 'replay'; ruleRef: string };
+  trigger:
+    | { kind: 'distinct-counterexamples'; threshold: number; lookbackMs?: number }
+    | { kind: 'minimum-sample'; minimum: number; windowMs: number }
+    | { kind: 'cadence'; cadence: 'daily' | 'weekly' | `every-${number}d` };
+}
+
+interface EvaluationSnapshot {
+  snapshotId: string;
+  objectiveId: string;
+  metricId: string;
+  ruleVersion: string;
+  window: { start: number; end: number };
+  episodeRefs: TraceEpisodeRef[];
+  annotationIds: string[];
+  createdAt: number;
+}
+
+interface MetricResult {
+  resultId: string;
+  snapshotId: string;
+  objectiveId: string;
+  metricId: string;
+  kind: MetricKind;
+  value:
+    | { kind: 'counter'; count: number; threshold: number }
+    | { kind: 'rate'; numerator: number; denominator: number; rate: number }
+    | { kind: 'semantic'; labels: Record<string, number>; explanation: string }
+    | { kind: 'replay'; passed: number; failed: number };
+  evaluatedAt: number;
+}
+```
+
+`EvaluationIndexer` 不是语义判断器。它只执行 manifest 中声明的确定性投影：`annotation.objectiveId + metricId + unitRefs` 校验注册关系，按 `incidentKey` 去重，维护查询索引/水位；没有 annotation 的 raw trace 进入 semantic sweep 候选索引，不被猜测归属。
+
+## 2. Stateful object census
+
+### 2.1 TraceEpisode closure
+
+Lifecycle owner：invocation terminal seam。prompt trace producer 只能创建 open trace；terminal seam 只能一次性闭合或幂等重放同一 closure。
+
+| Current state | Event | Next state | Side effect |
+|---|---|---|---|
+| absent | prompt trace persisted | open | 写 summary/detail/replay exposure |
+| open | terminal completed/failed/cancelled | closed | 写 terminal extension，注册 episode index |
+| closed | identical terminal retry | closed | no-op |
+| closed | conflicting terminal retry | closed | fail closed + anomaly log，不覆盖 |
+| absent | terminal before trace persist | terminal-pending | 暂存 terminal extension |
+| terminal-pending | late trace persist | closed | 原子绑定并删除 pending terminal |
+
+旁路约束：generic trace delete 只用于明确 owner-scoped 单 turn 删除；annotation/result store 不随之自动级联删除，以保留审计引用并显示 `source_missing`。
+
+不变量：
+
+- INV-1 一个 `invocationId` 最多对应一个 canonical episode closure。
+- INV-2 closure 的四个 join id 一旦写入不可修改。
+- INV-3 terminal retry 不产生第二个 episode。
+- INV-4 LLM/eval 错误不能改变 invocation terminal outcome。
+
+### 2.2 PendingTraceMarker
+
+Lifecycle owner：marker resolver（terminal seam 后异步执行）。MCP callback 只允许 create；不得直接 resolve、delete 或计数。
+
+| Current state | Event | Next state | Side effect |
+|---|---|---|---|
+| absent | authenticated MCP trigger | pending | append marker keyed by invocationId |
+| pending | episode closes | resolved | 原子创建 TraceAnnotation 并标记 resolved |
+| pending | same MCP retry | pending | incidentKey 幂等 no-op |
+| pending | terminal exists before marker | resolved | 读取 closure 后立即解析 |
+| pending | resolver crash after annotation append | resolved | annotation idempotency 后补 resolved marker |
+| pending | retention audit finds no invocation | orphaned | 记录 diagnostic；不伪造 annotation |
+
+不变量：
+
+- INV-5 pending marker 本身永不计入 Metric。
+- INV-6 marker 的 owner/subject 来自 server-trusted principal/invocation，不信任 body。
+- INV-7 resolve 后 annotation 必须引用 exact episode，禁止时间窗猜测。
+
+### 2.3 TraceAnnotation ledger
+
+Lifecycle owner：TraceAnnotationStore。无 update/delete API；修正通过追加 `supersedesAnnotationId`（V1 可先只支持 append）。
+
+| Current state | Event | Next state | Side effect |
+|---|---|---|---|
+| absent | append valid annotation | present | SETNX record + objective/metric/unclassified indexes |
+| present | same annotation retry | present | no-op |
+| present | same id different payload | present | fail closed |
+| unclassified episode | semantic annotation append | classified | 从 unclassified 工作索引 ACK，raw trace 不改 |
+| unclassified episode | irrelevant/unscorable append | terminal-classified | 避免每个周期重复送 LLM |
+
+不变量：
+
+- INV-8 三种 source 使用完全相同的 annotation schema。
+- INV-9 annotation append 与 index 更新原子化；重复 `incidentKey` 不重复计数。
+- INV-10 raw trace 内容不可被 annotation 回写或改写。
+
+### 2.4 EvaluationSnapshot / MetricResult
+
+Lifecycle owner：EvaluationScheduler 创建 snapshot，EvaluatorRunner 完成，MetricResultStore 追加结果。
+
+| Current state | Event | Next state | Side effect |
+|---|---|---|---|
+| no snapshot | trigger not ready | no snapshot | 只更新 readiness 观测，不显示 blocked |
+| no snapshot | trigger ready | queued | 原子冻结 snapshot + trigger watermark |
+| queued | worker starts | running | claim lease |
+| running | code/LLM/replay succeeds | completed | append MetricResult，commit watermark |
+| running | evaluator fails | retryable | 保留 snapshot，释放/超时 lease |
+| retryable | retry succeeds | completed | 同一 snapshot 只写一个 result |
+| completed | scheduler repeats same range | completed | watermark 防重复 run |
+
+不变量：
+
+- INV-11 snapshot 一旦创建不可修改；重试读取同一输入。
+- INV-12 count threshold 只数 distinct `incidentKey` episode，不数重复 annotation。
+- INV-13 counter 结果不包含虚构 denominator/rate。
+- INV-14 semantic worker 不在 invocation 主流程运行。
+- INV-15 completed watermark 只在 result 持久化成功后推进。
+
+### 2.5 Derived indexes/cursors
+
+索引与 readiness 全部是可重建投影；不得成为第二真相源。EvaluationIndexer 使用 per-owner cursor，advance 必须与目标索引写入原子化；cursor 丢失可从 annotation ledger 重放。
+
+## 3. Adversarial test matrix
+
+| Scenario | Expected | Invariants |
+|---|---|---|
+| terminal 先于 prompt trace persist | 后到 trace 自动闭合 | INV-1..4 |
+| terminal 双写且 payload 冲突 | 原 closure 保留，冲突可见 | INV-1..3 |
+| MCP marker 重试 3 次 | 只产生一个 annotation | INV-5..9 |
+| resolver 在 append 后 crash | 重启后补 resolved，不重复计数 | INV-7..9 |
+| 两个结构规则同时命中同一 incident | 同 incidentKey 只计一次 | INV-9,12 |
+| 3 个 distinct counterexample、阈值 3 | 恰好创建一个 snapshot | INV-11,12,15 |
+| 10 个 trace 无 annotation | 只进入 async sweep，不阻塞回复 | INV-4,10,14 |
+| LLM timeout/格式错误 | snapshot retryable，主 invocation 不受影响 | INV-4,11,14 |
+| evaluator 写 result 后在 watermark 前 crash | retry 读到同 result 并补 watermark | INV-11,15 |
+| trace 被 owner 删除后结果仍引用 | Console 显示 source_missing，不复活 trace | INV-10,11 |
+| 旧 SegmentJudgment Redis 数据存在 | 新 read model 完全忽略 | AC-9, AC-12 |

+
+### Task 6: Wire code/LLM/replay evaluators and retire SegmentJudgment from production truth

+- Disconnect legacy-only: `packages/api/src/domains/prompt-hooks/SegmentJudgmentCache.ts`
+- Disconnect legacy-only: `packages/api/src/infrastructure/harness-eval/manual-trigger/trigger-now-judgments.ts`
+- Replace tests: `packages/api/test/harness-eval/segment-judgment-engine.test.js`
+
+1. 写红测：zero guard events 仍可 sweep/evaluate；code evaluator deterministic；LLM failure retryable；replay input frozen。
+2. runner 按 metric `evaluator.kind` dispatch，未知 rule fail closed。
+3. daily/N-day 任务先跑 semantic sweep/readiness，再创建 snapshot；manual trigger 复用同 pipeline。
+4. 删除 SegmentJudgment 的 production wiring/cache/time-window attribution；legacy 模块只为旧 API/测试兼容保留，新 Console 和评估路径不实例化、不读取。legacy Redis keys 不读不迁移。
+5. 跑 manual/daily/lifeline focused tests；commit `refactor(f257): replace segment judgments with metric results`。
+
+### Task 7: Rebuild lifeline read model and Console
+
+**Files:**
+- Modify: `packages/api/src/routes/segment-lifeline.ts`
+- Modify: `packages/api/src/routes/segment-lifeline-chain.ts`

+
+1. 写红测：counter 显示“反例 3 次 / 阈值 3”且无 rate；Eval 显示归属/模型/指标/时间/窗口；trace replay 含 input/output/tool/segment scene。
+2. 新 `segment-evaluation` read model join manifest + latest MetricResult + episode refs；新 Modal 不读 SegmentJudgmentCache，也不渲染 legacy `EvalStagePanel/LifelineStageDetail`。
+3. tracing tab 改 episode replay theater；仅 ID 降为可复制 provenance。
+4. 编辑器对可写 text hook 直接编辑；移除模板来源/冗余预览；变量用 KV；readonly 保留明确原因。
+5. Browser/Playwright 截图验证；commit `feat(f257): present objective metrics and trace replay`。
+
+### Task 8: Update truth sources and purge only invalid derived fixtures
+
+**Files:**
+- Modify: `docs/features/F257-harness-ledger.md`
+- Mark superseded: `docs/features/assets/F257/objective-driven-redesign-v1.md`
+- Modify: `docs/architecture/ownership/cells/harness-eval.md`
+- Modify: `packages/mcp-server/src/server-toolsets.ts`
+- Modify relevant generated fixtures/tests only where they encode legacy judgment semantics.
+
+1. 文档明确 tracing/eval 分工、23 objectives、metric kinds、threshold/cadence、异步 LLM、无 Objective 状态机。
+2. 删除 repo 内旧派生 verdict fixture/测试期望（若存在）；不操作 Redis/SQLite/runtime data。
+3. 跑 convention graph 重新索引，核对 MCP contract consumers。
+4. commit `docs(f257): define annotation-driven objective evaluation`。
+
+### Task 9: Verification and review
+
+1. `pnpm --filter @cat-cafe/shared build`。
+2. `pnpm --dir packages/api build`。
+3. 运行所有新增/修改 focused tests；预期 0 fail。
+4. 运行 F257 Redis isolated suite；预期 0 fail。
+5. `pnpm biome check . --diagnostic-level=error` 与 `git diff --check`。
+6. `pnpm --dir packages/api test:public`；预期 0 fail。
+7. 生成 UI screenshots 和 exact SHA evidence。
+8. 请求跨家族 fresh-context review；作者不得自审。
+
+## 5. Technical decisions resolved during implementation
+
+- invocation exact id 的现有来源若不贯穿 route，将在 invocation request object 上增加一个 server-generated id；不得以 timestamp proximity 代替。
+- `outputText` 只在现有 message persistence policy 允许的范围引用/读取；优先存 outputMessageId，避免复制敏感/长文本。
+- annotation correction V1 若无产品入口，仅保留 append-only + deterministic id；不为未提出的人工编辑造 UI。
+- semantic sweep 的 budget/批次沿用 eval-domain scheduler，失败不升级为 Objective blocked。
+- 旧 `SegmentJudgment` 源文件暂留给历史 API/回归测试，但 bootstrap、manual/daily eval、新 `segment-evaluation` read model 与新 Console 均不再消费它。这是“退出生产真相”，不是对旧派生数据做兼容迁移。
+
+## 6. No operator value questions
+
+本轮价值判断均已由 co-creator 明确：旧不合适数据可清理/忽略；tracing 与 eval 分离；MCP 是 trigger；语义分析异步；反例 count threshold 不强求分母。因此没有待升级的价值 OQ。

+ * LI-005 Phase 1 — A2A Ack Liveness Detection (接球执行触发存活性检测).
+ *
+ * 检测猫通过 A2A 接到球后（inline @mention 或 queue-dispatched），invocation 结束时
+ * 既无路由出口（行首 @mention / @co-creator / structured routing）也无持久触发器
+ * （hold_ball / register_scheduled_task / register_pr_tracking /
+ * register_issue_tracking / community_await_external），导致球静默死亡——
+ * 无机制保证后续执行。
+ *
+ * Phase 1 scope: detection + hint + observability（ball.void_ack 事件 + telemetry）。
+ * Phase 2（structural rejection / auto-wake）待 Phase 1 收集数据后实施。
+ *
+ * 声明-动作一致性检查的延伸：void-hold 查"说持球没做"，
+ * ack-liveness 查"接了球没绑触发器"。
+ *
+ * A2A 路径信号（isA2AInvocation）:
+ *   - inline serial: `directMessageFrom`（routeSerial a2aFrom map 中 catId）
+ *   - queue-dispatched: `queueTriggerReplyTo`（derived from `a2aTriggerMessageId` in options）
+ * `a2aTriggerMessageId` 已确认为 **cat→cat 专属**——5 个赋值点全部在 A2A 路径
+ * （callback-a2a-trigger.ts 3 处 + route-serial.ts inline/deferred 2 处），
+ * 0 个 operator/user/connector 路径设置此字段。operator 发起的 invocation
+ * 不会被误判为 A2A。详见 Fable ① 核验（2026-07-16 Explore agent 穷举确认）。
+ *
+ * 纯函数、零 IO、可测。
+ *
+ * @see void-hold-detect.ts — 同族守卫，模式参照
+ * @see docs/features/assets/li005-ack-liveness/live-candidates-2026-07-14.md — LI-005 定义

+ * Criteria: the tool MUST register a system mechanism (timer, webhook, cron)
+ * that will invoke the cat in the future. Pure bookkeeping tools (create_task)
+ * do NOT qualify — they create visible panel items but have no invokeTrigger
+ * or scheduled wake.
+ *
+ * Order doesn't matter (Set-based lookup). The list uses suffix matching
+ * to cover both `mcp__cat-cafe-collab__cat_cafe_hold_ball` and
+ * `cat_cafe_hold_ball` forms.

+ * Caller contract (all providers, per Sol R4):
+ *   All providers now emit tool_result events — Claude CLI's user-turn
+ *   tool_result content blocks are bridged in claude-ndjson-parser.ts (R4).
+ *   Route-serial passes only confirmed-successful tool names via
+ *   `classifyDurableTriggerResult` into `confirmedCallbackToolNames`.

+ * by prompt text (O2 观测层): governance-l0 「用自己的身份签名 `[昵称/模型🐾]`,
+ * 签名必须含模型型号」. dev-7a882ba0: Fable 漏签靠 operator 人工发现 — zero
+ * structural coverage. This module upgrades the convention to a regex-decidable
+ * structural assertion (O1 结构强制): does an agent message end with a
+ * contract-shaped `[nickname/model🐾]` signature?
+ *
+ * STRICTNESS (sol R1 P1-3). This is a COMPLIANCE lint, so it asserts the current
+ * contract shape — nickname + '/' + model + 🐾 — and does NOT reuse
+ * `isCatSignatureLine` from `cat-signature-strip.ts`. That matcher is a
+ * routing-STRIP matcher, permissive BY DESIGN (it also accepts pawed-slashless
+ * `[Spark🐾]` and legacy un-pawed `[砚砚/GPT-5.5]` so historical routing suffixes
+ * still get stripped). Reusing it as a compliance predicate produced false
+ * negatives — model-less / paw-less signatures counted as compliant. The two
+ * matchers are kept separate: strip = permissive (routing), lint = strict
+ * (compliance). Scope split: presence-only (contract SHAPE present) — matching
+ * the signature to the POSTING cat (identity-correctness) stays deferred.
+ *
+ * SCOPE — two-phase (F257 owner vision-guardian review 2026-07-20; AC 完成 ≠
+ * feature 完成). This module + the persistence seams are the **detection layer**
+ * (O1 structural detection, message-level observable). The harness **ledger

+ * projection and implements the §4.5.1 collection-integrity contract:
+ *   ① persisted owner-scoped high-watermark (highest projected authority id)
+ *   ② reconcile-before-evaluate: authority vs projection window对账 with
+ *      synchronous idempotent rebuild; rebuild failure → metrics unmeasurable
+ *   ③ projection worker errors are never silently swallowed — they are logged
+ *      AND persisted to an error ZSET (collection-health visibility)
+ *
+ * Metric semantics (@解析成功率 per parserMode): T-A (§3.4) via the mapping
+ * functions in routing-attempt.ts — not restated here.
+ *
+ * Redis-only by design: the in-memory MessageStore has no projection; metric
+ * endpoints report unmeasurable without Redis.

Each rollup covers the LATEST 24h in-memory snapshot (event buffer has 24h retention; the weekly firing frequency is how often the eval cat runs, NOT the data window).

Signal 2 (blindness — MORE dangerous, token account INVISIBLE): reference-read the latest eval:task-outcome verdict/trend — if task-outcome quality (corrected_success / needs_investigation rates) worsened after anchor deployment and correlates with anchor tool usage, this is the insidious signal that preview is causing judgment errors. F236 does NOT write to eval:task-outcome; cross-reference only. VERDICT MAPPING: Both signals (tax + blindness evidence) → delete_sunset with governance.cvoAcceptRequired=true; ownerAsk.requestedAction MUST specify WHICH tool(s) to sunset. Signal 1 only (tax, no blindness evidence) → fix (investigate whether preview quality can improve to reduce drill rate).

+ * F257 V2/Phase B — canonical guard-rejection episode coalescer.
+ *
+ * PR #41 verdict (eval:harness-ledger, 2026-07-19-harness-ledger-burst-coalescing-fix-c2):
+ * four hold_ball 429s within 7.044s were counted as four independent 3-per-7d
+ * escalation incidents — raw request count is NOT distinct incident count.
+ *
+ * This module is the SINGLE coalescing implementation (sol scope ruling,
+ * msg 0001784468875582): both the real-time threshold path
+ * (guard-threshold-escalation) and the snapshot/bundle path
+ * (harness-ledger-snapshot-provider → generator adapter) must call it.
+ * Two implementations would reintroduce accounting drift.
+ *
+ * Contract:
+ * - Group key: guardId + threadId + catId. ALL THREE must be trusted
+ *   non-empty values — an event with an untrusted key forms its own episode
+ *   and never co-mingles (prevents unknown-identity mis-merges).
+ * - Stable total order: timestamp asc, tie-broken by eventId asc.
+ *   eventId is the per-raw-rejection coordinate; episodeId is a DERIVED
+ *   coordinate — the two must never be interchanged.
+ * - Chaining: within a group, an event whose gap to the previous event is
+ *   ≤ EPISODE_GAP_MS extends the current episode (gap-based, matching
+ *   "rapid retry" semantics — a fixed time bucket would split long chains).
+ * - Deterministic: same input set (any order) → identical episode list,
+ *   so historical windows are replayable and bundles independently
+ *   recheckable.
+ *
+ * EPISODE_GAP_MS = 60s covers the known 1s/2s/4s retry backoff envelope
+ * plus scheduling jitter (sol parameter ruling). V2 deliberately ships NO
+ * per-guard/operator config surface — revisit only with committed episode
+ * evidence (V3+).

+/**
+ * F257 V2/Phase B — MCP client-layer guard rejection ingest + ledger query
+ * surface (AC-B1 dual entry + "queryable by ledger id").
+ *
+ * POST: MCP-local fail-closed rejections (e.g. cross_post_message without
+ * routing credentials) never reach the API route that would normally emit a
+ * guard rejection event — the MCP layer reports them here fire-and-forget
+ * (fail-open client side; see packages/mcp-server/src/tools/guard-rejection-report.ts).
+ *
+ * GET: the AC-B1 acceptance step is "trigger a 429 + an MCP-local reject →
+ * query BY LEDGER ID returns both" — this is that consumer surface, also
+ * carrying AC-B2 pot stats (anomalyRefCount + how_counted).
+ *
+ * Trust boundary (V1 three-axis provenance discipline; sol review P1-1/P1-3):
+ * - BOTH principal kinds accepted (requireCallbackPrincipal): invocation
+ *   principals carry trusted threadId/invocationId; agent-key principals
+ *   carry NO thread binding — their thread coordinate is taken from the
+ *   payload but VERIFIED through the scoped-thread resolver (owner check),
+ *   degrading to 'unknown' (coalescer untrusted-key isolation) on any
+ *   failure. Identity (catId/userId) always comes from the principal.
+ * - guardId whitelist uses Object.hasOwn — `in` walks the prototype chain
+ *   and would accept 'toString'/'constructor' and mint function ledgerIds.
+ * - eventId / timestamp are server-generated (client clocks untrusted).

+ * F257 #6 slice 6c — 判据② eval window / denominator provenance contract tests.
+ *
+ * Root cause (static call chain, sol proposal): the lifeline endpoint's
+ * `window` is the CURRENT QUERY window; `SegmentJudgment` had the precise
+ * eval `window + denominatorKind`, but `CachedJudgment` persisted only
+ * counts + `evaluatedAt` — so the UI projected incomparable metrics
+ * (tracing(18) from the query window vs eval injectionCount=0 from a
+ * historical eval window) into the same context as if contradictory.
+ *
+ * Contract (sol, source thread 2026-07-22):
+ *   - producer-written CachedJudgment MUST carry window + denominatorKind;
+ *   - only legacy Redis JSON reads may lack them → explicit null (fail-visible);
+ *   - window semantics [startMs, endMs) — evaluatedAt is NOT a window;
+ *   - the judgment's OWN eval window must never be replaced by the query window.

+ * store + a prewarmed manifest cache (sol's recipe — no broad full-suite driver): a

+ * Covers (per T-A "V1 实现动作" column, full set):

+ *  - tokenOrdinal assigned once after all passes merge, ordered by span start
+ *  - parser 改造①: self_excluded tokenized (a2a)
+ *  - parser 改造②: unknown_token emitted before line break (a2a)
+ *  - (右截断): cap ≠ truncated — read-only scan must confirm extra
+ *    metric-affecting tokens before truncated=true / batch metricEligible=false
+ *  - parser 改造③: duplicate = distinct-span-same-target only; same-span
+ *    re-visit is a traversal artifact (merged silently, outcome unchanged)

+// F257 V2/Phase B — PR #41 verdict regression (episode coalescing).
+//
+// Verdict 2026-07-19-harness-ledger-burst-coalescing-fix-c2 (MERGED, fix):
+//   "Change F257 escalation accounting to preserve rawEventCount but coalesce
+//    same-guard, same-thread, same-cat rapid retries into a distinct episode
+//    count used by the 3-per-7d threshold; carry episode and sample-anchor
+//    metadata into the committed bundle."
+//
+// Three mandated regressions (sol scope ruling, msg 0001784468875582):
+//   R1: four hold_ball 429s in one 7-second episode → rawEventCount=4,
+//       episodeCount=1, does NOT alone trigger the three-episode threshold
+//   R2: three separated episodes still trigger
+//   R3: isolated A2A streak-4 block stays independently attributable
+//
+// Coalescing contract (sol ruling):
+//   - group key: guardId + threadId + catId — ALL three must be trusted
+//     non-empty values, else the event forms its own episode (no unknown-merge)
+//   - stable sort: timestamp asc, tie-break by per-event unique id (eventId —
+//     the raw-rejection coordinate; episodeId is derived, never interchanged)
+//   - adjacent gap ≤ EPISODE_GAP_MS (named constant, 60s, no per-guard config

+ * F257 V2 — skip-reason eligibility registry + escalation filter tests.
+ *
+ * Sol R2 fixes:
+ * P1-1: truncation → always conservative-true (unscanned tail may be eligible)
+ * P1-2: byReason null-prototype (prototype pollution prevention)
+ * P2-1: producer exhaustiveness (queue_pending removed from union, satisfies)
+ * P2-2: committed bundle/provenance tests via generator adapter
+ * P2-3: real append→hook integration test
+ *
+ * Sol R3 fixes:
+ * P1-1: claim lifecycle — uncertainty_probe (1h) vs confirmed (7d) separation;
+ *        truncation-only claims don't suppress subsequent real harm
+ * P2-1: synthetic pingpong_streak reason bound to producer type
+ *
+ * [宪宪/claude-opus-4-6🐾]

+/**
+ * F257 fix (verdict PR #39): hold_ball must NOT auto-retry on 429.
+ *
+ * Root cause: callback-retry treats 429 as retryable (shouldRetryStatus).
+ * hold_ball's 429 means "MAX_HOLDS_PER_WINDOW (3/h) reached" — the window
+ * is 1 hour, so retrying in 1s/2s/4s will never succeed. The default retry
+ * policy caused 3 identical POSTs, each emitting a GuardRejectionEvent,
+ * hitting the threshold-escalation trigger on retry noise rather than
+ * genuine independent violations.
+ *
+ * Fix: handleHoldBall passes { retryDelaysMs: [] } to callbackPost, making
+ * it a single-attempt call. The 429 error is still surfaced to the cat.
+ *
+ * Evidence: 3 events in 3,032ms from thread_mrkn6povq4zzgh45/gpt52,
+ * intervals ~1,016ms and ~2,016ms matching DEFAULT_RETRY_DELAYS_MS [1000, 2000, 4000].
+ *
+ * Fixture env vars: CAT_CAFE_API_URL, CAT_CAFE_INVOCATION_ID, CAT_CAFE_CALLBACK_TOKEN
+ * (matches getCallbackConfig in callback-tools.ts:139-165). Higher-priority
+ * credential sources (CAT_CAFE_CREDENTIAL_FILE, agent-key variants) are
+ * explicitly cleared so the test is self-contained and CI-portable.

Why: close fresh-context FC-1 by making the merge logic import-safe and continuously testing metadata preservation, insertion, deduplication, and idempotency.

Subject: [PATCH 3/6] fix(harness): preserve eval ownership continuity
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Why: the historical F257 snapshot replaced newer origin/main ownership for F266/F267/F278 and left dangling anchors. Rebuild the cell as a union and add a gate that rejects dropped base ownership or missing code anchors.

Subject: [PATCH 4/6] test(harness): migrate upstream cursor writers

Why: the refreshed upstream cursor tests append messages through the F257-enforced store contract, so every fixture writer must declare explicit author, routing, and observation provenance instead of failing closed at runtime.

Subject: [PATCH 5/6] test(harness): migrate latest-main message fixtures
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Why: latest upstream tests bypass TypeScript and still wrote messages without the F257 provenance contract, causing the refreshed Harness gate to fail closed. Migrate real fixture writers while preserving the intentional missing-provenance regressions, and seed capability-wakeup registry in the live root the adapter reads.

Subject: [PATCH 6/6] style(harness): organize provenance parser imports
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Why: the refreshed Harness candidate passed the full test suite but the repository-wide Biome check rejected the provenance parser's import ordering. Apply Biome's deterministic safe ordering without changing runtime behavior.
