+- **Evidence boundary:** [discussion evolution and current-implementation measurements](../../../packages/loopx-jev/DESIGN_DECISIONS.md); deterministic integration checks are distinct from provider accuracy and task benefit. No automatic intervention or native host-hook rollout.
+- **Pending:** maintainer acceptance of this optional-tool scope and independently evaluated comparative value. The earlier M0 intake is not retroactive implementation approval.

+# Progress-Review Sentinel
+
+[中文](README.zh-CN.md)
+
+The progress-review sentinel lets a Goal consume **typed drift receipts** that
+an optional, external, bounded reviewer writes after each captured work
+transition. It is default-off. In `shadow` the core only records and displays
+receipts. In `assist` a run of consecutive completed drift receipts becomes the
+**existing** `autonomous_replan_obligation`; nothing else changes.
+
+It exists because the typed repeat fuse is blind by construction to one
+pattern: an Agent that keeps declaring `advanced`, keeps changing its
+`hypothesis_id`, and keeps the tests green while its scoped file delta only
+renames identifiers or reorders fields. That work is caught today only by the
+periodic review after 20 durable runs.
+
+## What the core does and does not do
+
+| The core | Never |
+| --- | --- |
+| Reads receipts through one strict schema, `progress_review_receipt_v0` | Calls a model, reads a raw delta, or imports the observer package |
+| Joins receipts to run rows by `turn_instance_id`, else by `(generated_at, agent_id)` | Overwrites or supplements the Agent's own `progress_observation` |
+| Counts only `completed` receipts whose selected drift signal is `True` | Counts `unknown`, `abstained`, `failed`, `stale` or missing receipts |
+| Stops the streak at an acknowledged autonomous replan and re-arms | Pauses turns, opens user gates, or settles Goal acceptance |
+| Requires one goal contract revision across the counted receipts | Keeps receipts alive across an acceptance-contract change |
+
+The typed repeat fuse keeps precedence. A receipt streak only adds evidence
+when that fuse is quiet.
+
+## Policy
+
+```bash
+loopx configure-goal --goal-id <goal-id> --progress-review-mode shadow --execute
+loopx configure-goal --goal-id <goal-id> --progress-review-mode assist \
+  --progress-review-signal noul --progress-review-drift-threshold 2 --execute
+loopx configure-goal --goal-id <goal-id> --clear-progress-review-configuration --execute
+```
+
+| Field | Values | Meaning |
+| --- | --- | --- |
+| `mode` | `off`, `shadow`, `assist` | `off` loads nothing; `shadow` records and displays; `assist` may raise the obligation |
+| `signal` | `noul`, `choice` | Which receipt judgment pair counts as drift |
+| `drift_threshold` | 2–20 | Consecutive completed drift receipts before an obligation |
+
+The policy lives at `control_plane.progress_review` in the goal registry and is
+visible in `loopx configure-goal --goal-id <goal-id>` under `feature_summary`
+and in the Dashboard capability editor. A malformed block fails closed to `off`.
+
+## Receipts
+
+Receipts are written to
+`<runtime-root>/goals/<goal-id>/progress-review/receipts/<event-id>.json` by
+the observer in the optional `loopx-jev-pilot` distribution
+([`packages/loopx-jev/DRIFT_SHADOW.md`](../../../packages/loopx-jev/DRIFT_SHADOW.md)).
+Each receipt carries only typed fields:
+
+- identity: `goal_id`, `event_id`, `evidence_id`, `contract_revision`, `sequence`,
+  and the run's `turn_instance_id`, `generated_at`, `agent_id`, `todo_id`;
+- `status`: `completed`, `abstained`, `failed`, `not_evaluated`, `stale`;
+- `judgments.choice`: `relation` and `increment` labels or null;
+- `judgments.noul`: probabilities for `behavior_change`, `serves_acceptance`,
+  `evidence_increment`, or null;
+- `drift_signal.noul` and `drift_signal.choice`: `true`, `false` or null;
+- `timing_ns`, `usage`, `label_probability_threshold`, `recorded_at`.
+
+The drift signals are derived by the observer with its configured label
+threshold `t`:
+
+- `noul`: `P(behavior_change) ≤ 1−t` **and** `P(serves_acceptance) ≤ 1−t` is
+  drift; either probability `≥ t` is not drift; anything else is null.
+- `choice`: `relation = off_goal` **and** `increment = no_new_evidence` is
+  drift; `on_goal`, `necessary_prerequisite` or `new_evidence` is not drift;
+  anything else is null.
+
+Documentation-only or test-only work that serves an acceptance criterion is
+therefore not drift under either signal.
+
+## What you see
+
+`loopx status --format json` adds `external_progress_review` to a goal item and
+its `project_asset` whenever the policy is not `off`: receipt counts by status,
+drift counts per signal, and the latest receipt's typed judgments. In `assist`,
+a qualifying streak appears as an `autonomous_replan_obligation` whose trigger
+`kind` is `external_progress_review_drift`, with `frontier_identity`
+`progress_review:<evidence-id>`, a P1 todo action, and the usual
+`required: true`, `stop_condition` and ack contract. The heartbeat prompt
+already instructs Agents to obey that obligation and acknowledge it with a
+typed replan.
+
+## Verifying the differential
+
+`packages/loopx-jev` ships a comparison harness:
+
+```bash
+loopx-jev sentinel compare \
+  --matrix packages/loopx-jev/tests/fixtures/sentinel/matrix.json \
+  --responses packages/loopx-jev/tests/fixtures/sentinel/responses \
+  --output /tmp/sentinel-comparison.json
+```
+
+For every recorded sequence it reports the first round at which the typed
+repeat fuse would fire (never, within the sequence, for self-declared
+advancement), the first round at which each receipt signal flags drift, and the
+false flags on sequences whose gold label is on-goal. Without `--live` it
+replays committed provider responses, so the numbers reproduce in CI without a
+key. `python3 examples/progress-review-sentinel-smoke.py` runs the same replay.
+
+## Recorded differential
+
+The committed live recording of the 16-sequence matrix (`jev-1.13.0`, 35 rounds,
+every round self-reporting `advanced`):
+
+| | Typed repeat fuse | `noul` receipts | `choice` receipts |
+| --- | --- | --- | --- |
+| Drift sequences flagged at or after their gold round | 0/9 | 6/9 | 4/9 |
+| Reaching the `assist` obligation at threshold 2 | 0/9 | 6/9 | 1/9 |
+| Real on-goal upstream commits falsely flagged | 0/7 | 0/7 | 0/7 |
+
+All six purely cosmetic sequences were flagged at round 1 and would raise the
+obligation at round 2, against a periodic review that waits for 20 durable runs.
+Cosmetic churn after a real implementation in the same file was not flagged, and
+one executed negative probe was flagged in two of three live runs. See the
+[operation guide](../../../packages/loopx-jev/DRIFT_SHADOW.md) for the full table,
+latency and variance.
+
+## Boundaries and next step
+
+Escalation (a user gate after an ignored obligation) and pause remain future
+work and are not granted here. The observer's prediction quality is a separate
+question from this integration; run one Goal in `shadow`, label its receipts
+with `loopx-jev drift label`, and compare first-flag rounds before enabling
+`assist`.

+# 进展评估哨兵
+
+[English](README.md)
+
+进展评估哨兵让一个 Goal 消费**类型化的漂移回执**。回执由一个可选的、外部的、有界评估器在每次捕获到的工作转换后写入。能力默认关闭。`shadow` 模式下核心只记录和展示回执；`assist` 模式下，连续若干条已完成的漂移回执会变成**已有的** `autonomous_replan_obligation`，除此之外不改变任何行为。
+
+它要补的是现有类型化重复保险丝按构造看不见的一种情形：Agent 每轮自报 `advanced`、每轮更换 `hypothesis_id`、测试始终全绿，但限定文件的实际变化只是改名和调整字段顺序。今天这类工作只能在 20 条 durable run 之后由周期复审兜底发现。
+
+## 核心做什么、不做什么
+
+| 核心会 | 核心不会 |
+| --- | --- |
+| 只通过一个严格 schema `progress_review_receipt_v0` 读取回执 | 调用模型、读取原始 diff、导入观察器包 |
+| 按 `turn_instance_id` 关联 run 行，缺失时退回 `(generated_at, agent_id)` | 覆盖或补充 Agent 自己的 `progress_observation` |
+| 只计入状态为 `completed` 且所选漂移信号为 `True` 的回执 | 把 `unknown`、`abstained`、`failed`、`stale` 或缺失的回执算作漂移 |
+| 在已确认的自主重规划处停止计数并重新武装 | 暂停 Turn、打开 user gate、判定 Goal 验收 |
+| 要求被计数的回执共享同一个 Goal 契约修订 | 让契约变化前的回执继续生效 |
+
+类型化重复保险丝保持优先。只有它沉默时，回执连续段才会补充证据。
+
+## 策略
+
+```bash
+loopx configure-goal --goal-id <goal-id> --progress-review-mode shadow --execute
+loopx configure-goal --goal-id <goal-id> --progress-review-mode assist \
+  --progress-review-signal noul --progress-review-drift-threshold 2 --execute
+loopx configure-goal --goal-id <goal-id> --clear-progress-review-configuration --execute
+```
+
+| 字段 | 取值 | 含义 |
+| --- | --- | --- |
+| `mode` | `off`、`shadow`、`assist` | `off` 不加载任何内容；`shadow` 记录并展示；`assist` 可以触发义务 |
+| `signal` | `noul`、`choice` | 哪一组判断算作漂移 |
+| `drift_threshold` | 2–20 | 触发义务前需要的连续已完成漂移回执数 |
+
+策略保存在 Goal 注册表的 `control_plane.progress_review`，可在 `loopx configure-goal --goal-id <goal-id>` 输出的 `feature_summary` 和 Dashboard 能力编辑器中看到。格式错误的配置块会安全地退回 `off`。
+
+## 回执
+
+回执由可选的 `loopx-jev-pilot` 发行版中的观察器写入 `<runtime-root>/goals/<goal-id>/progress-review/receipts/<event-id>.json`（见 [`packages/loopx-jev/DRIFT_SHADOW.zh-CN.md`](../../../packages/loopx-jev/DRIFT_SHADOW.zh-CN.md)）。每条回执只包含类型化字段：
+
+- 身份：`goal_id`、`event_id`、`evidence_id`、`contract_revision`、`sequence`，以及 run 的 `turn_instance_id`、`generated_at`、`agent_id`、`todo_id`；
+- `status`：`completed`、`abstained`、`failed`、`not_evaluated`、`stale`；
+- `judgments.choice`：`relation` 与 `increment` 标签或 null；
+- `judgments.noul`：`behavior_change`、`serves_acceptance`、`evidence_increment` 的概率或 null；
+- `drift_signal.noul`、`drift_signal.choice`：`true`、`false` 或 null；
+- `timing_ns`、`usage`、`label_probability_threshold`、`recorded_at`。
+
+漂移信号由观察器按其配置的标签阈值 `t` 推导：
+
+- `noul`：`P(behavior_change) ≤ 1−t` **且** `P(serves_acceptance) ≤ 1−t` 为漂移；任一概率 `≥ t` 为非漂移；其余为 null。
+- `choice`：`relation = off_goal` **且** `increment = no_new_evidence` 为漂移；`on_goal`、`necessary_prerequisite` 或 `new_evidence` 为非漂移；其余为 null。
+
+因此，服务于验收条件的纯文档或纯测试工作在两种信号下都不算漂移。
+
+## 你会看到什么
+
+只要策略不是 `off`，`loopx status --format json` 会在 Goal 条目及其 `project_asset` 中增加 `external_progress_review`：按状态统计的回执数、按信号统计的漂移数，以及最新回执的类型化判断。`assist` 模式下，满足条件的连续段表现为一个 `autonomous_replan_obligation`，其 trigger 的 `kind` 为 `external_progress_review_drift`，`frontier_identity` 为 `progress_review:<evidence-id>`，附带一条 P1 todo 动作以及一贯的 `required: true`、`stop_condition` 和 ack 契约。心跳提示词已经要求 Agent 遵守该义务并用类型化重规划确认。
+
+## 验证差异
+
+`packages/loopx-jev` 附带对照命令：
+
+```bash
+loopx-jev sentinel compare \
+  --matrix packages/loopx-jev/tests/fixtures/sentinel/matrix.json \
+  --responses packages/loopx-jev/tests/fixtures/sentinel/responses \
+  --output /tmp/sentinel-comparison.json
+```
+
+它对每个录制序列报告：类型化重复保险丝首次触发的轮次（对自报 advanced 的序列在序列内永不触发）、每种回执信号首次标记漂移的轮次，以及 gold 标注为 on-goal 的序列上的误报。不加 `--live` 时回放已提交的 provider 响应，因此 CI 无需 key 即可复现数字。`python3 examples/progress-review-sentinel-smoke.py` 运行同一回放。
+
+## 录制对照结果
+
+16 序列矩阵的已提交 live 录制（`jev-1.13.0`，35 轮，每轮自报 `advanced`）：
+
+| | 类型化重复保险丝 | `noul` 回执 | `choice` 回执 |
+| --- | --- | --- | --- |
+| 在 gold 轮或之后标记的漂移序列 | 0/9 | 6/9 | 4/9 |
+| 阈值 2 下达到 `assist` 义务 | 0/9 | 6/9 | 1/9 |
+| 真实 on-goal 上游提交被误报 | 0/7 | 0/7 | 0/7 |
+
+6 个纯装饰性序列全部在第 1 轮被标记、第 2 轮即可触发义务，而周期复审要等 20 条 durable run。真实实现落地后对同一文件的装饰性改动未被标记；一次已执行的负结果探测在三次 live 中有两次被标记。完整表格、延迟与波动见[操作指南](../../../packages/loopx-jev/DRIFT_SHADOW.zh-CN.md)。
+
+## 边界与下一步
+
+升级（义务被忽略后打开 user gate）与暂停仍是未来工作，本能力不授予。观察器的预测质量与本集成是两个独立问题：先让一个 Goal 运行在 `shadow`，用 `loopx-jev drift label` 标注回执，比较首次告警轮次后再开启 `assist`。

+# Task-progress observation: design decisions and evidence
+
+[中文](DESIGN_DECISIONS.zh-CN.md) · [Operation guide](DRIFT_SHADOW.md) · [Research RFC](../../docs/architecture/rfcs/optional-semantic-assistance-jev-v0.md)
+
+Current implementation review: [PR #4854](https://github.com/loopx-project/loopx/pull/4854).
+
+**Current proposal:** ship task-progress observation as an explicitly installed,
+default-off tool, plus a default-off core policy (`progress_review`) that can
+record its typed receipts (`shadow`) or let consecutive completed drift receipts
+raise the **existing** autonomous replan obligation (`assist`). No pause, gate or
+acceptance authority is added. The decision requested is whether to accept this
+bounded closed loop and its recorded differential, not whether Jev has proved
+useful enough to control an Agent on its own.
+
+## Implemented functionality and observed effect
+
+The current delivery is a usable **capture → assess → inspect** path, enabled
+at an explicitly wrapped refresh call. It does not automatically observe every
+native Agent session.
+
+| Implemented functionality | Concrete effect and verification boundary |
+| --- | --- |
+| `drift init` binds a Goal contract, exact files and an initial checkpoint | Subsequent wrapped refreshes collect actual before/after material without hand-written artifact summaries; scope and contract still need operator selection. |
+| `drift refresh` captures around the real core command | Net file/evidence changes are associated with a durable run. Original stdout and exit code are retained; all 10 live-check run records remained unchanged. Collection adds measured overhead. |
+| Separate `drift drain` consumer | Jev evaluates Goal relation and evidence increment outside core transactions. All 10 requests in this run returned, but the decorative-work case was not detected. |
+| Durable deduplication, request budget and revocation checks | Repeated events are not additional evidence; saved answers can survive a consumer restart without a new request. Offline tests cover duplicates, unresolved sends, changed contracts/configuration and failures; this is not full long-horizon recovery qualification. |
+| Local off/shadow settings and environment-only key | Operators can enable, disable and read back the observer. Missing credentials, denied egress and request failure leave the existing Agent workflow in place. No automatic fallback judge or control action is added. |
+| `drift status` and phase timings | Operators can inspect judgments, unknowns, failures and capture/assessment time. No raw private source is printed by this status surface; the record supports review, not acceptance certification. |
+
+Validation covers 61 package tests plus 35 related core regressions (96 passing,
+no skips), strict source typing and lint, documentation checks, and a built-wheel
+CLI journey in an independent environment. **The observation workflow is
+implemented; reliable drift detection and reduced wasted work are not proven.**
+
+In practical terms, the tool removes the need to hand-write the selected diff
+packet and makes an additional assessment inspectable; the amount of operator
+time saved has not been measured. In current checks it recognized the retry
+implementation and necessary failing test as related to the Goal. It did not
+identify decorative renaming as drift, and it cannot certify a missing helper's
+behavior. No Agent was redirected or stopped, so these runs do not measure
+correction success, earlier intervention or final task-completion improvement.
+
+This is a public-safe decision record, not a transcript or an approval receipt.
+[RFC PR #4749](https://github.com/loopx-project/loopx/pull/4749) and
+[Discussion #4838](https://github.com/loopx-project/loopx/discussions/4838)
+preserve the public discussion. Earlier claims in that discussion are historical;
+the limitations below are essential to interpreting the current proposal.
+
+## How the proposal changed
+
+| Question / earlier claim | Challenge or observation | Retained decision |
+| --- | --- | --- |
+| Can semantics detect busy work that the repeat fuse misses? | An `advanced` self-report or changed fingerprint can evade that specific repeat condition. This does not prove that the entire Agent/review/acceptance system is blind. | Investigate earlier evidence-based observation; retain existing acceptance and control authority. |
+| Is Jev a strict superset of the rule? | A few constructed cases, including hand-written artifact descriptions, cannot establish that claim or a production error rate. | Drop the strict-superset claim; collect attributable before/after artifacts and preserve unknowns. |
+| Should Jev replace the working Agent's judgment? | An independent read-only Agent can assess the same material too. Role separation, evidence preparation and provider choice are different treatments. | Keep the existing Agent workflow; no fallback judge is implicitly launched by this package. |
+| Should every explored direction ship? | Candidate ranking experiments also depended on reducers, contexts and different Agent entrypoints. Their results do not qualify drift detection. | Only task-progress observation ships in this proposal. Other direction code, ranking reducers, selector changes and unrelated workflows are excluded. |
+| Is the change just three model questions inside refresh? | Refresh has its own state-write transactions. Network failures must not interrupt those writes; repeated polling must not create repeated drift evidence. | Bounded capture around the command, inference in another process, durable event/request deduplication and historical-only results. |
+| Is a delta sufficient evidence? | A new test or probe may be uninterpretable without unchanged surrounding code. | Supply both scoped checkpoints plus the delta. Do not silently truncate required context to fit a request. |
+| Does a fast response justify automatic correction? | Later checks still abstained on decorative changes and disagreed on evidence increment. Capture itself also adds latency. | Keep off/shadow. High probability is not a correctness guarantee; no-new-evidence is not itself drift. |
+
+## Current implementation: execution results
+
+The following checks exercised this task-progress observation implementation at source revision
+`2f4783bdd`. They used the installed `drift init/refresh/drain/status` entrypoints,
+real Git/files, an isolated Goal fixture and real Jev API calls. They are
+implementation checks on small constructed tasks, not independent production
+qualification or native long-running Agent sessions. Private workspaces, raw
+model traffic and credentials are not part of the public record.
+
+Five scenarios were each run twice: implement a retry, rename an unrelated
+constant, add a necessary failing test, produce a negative probe result, and
+change a call whose external helper implementation is absent. The failing test
+and probe actually ran. Expected labels were fixed before requests. The model
+was pinned to `jev-1.13.0`, selected-label probability threshold to 0.6 and request
+deadline to the default 5 seconds; input included both scoped checkpoints and
+the delta. Credentials came from the consumer environment.
+
+| Measurement | Result |
+| --- | ---: |
+| New requests / parseable responses | 10 / 10 |
+| Timeouts / full abstentions | 0 / 0 |
+| Cases with matching classifications across both repeats | 5/5 |
+| Exact two-label match to fixed expectations | 4/10 |
+| Client assessment median | 746 ms |
+| Request-to-headers median | 646 ms |
+| Synchronous capture overhead median | 334 ms |
+| Whole consumer process median | 824 ms |
+| Input tokens median | 1217 |
+
+| Scenario (two equal results each) | Goal relation | Evidence increment |
+| --- | --- | --- |
+| Retry implementation | on_goal | new_evidence |
+| Decorative renaming | unknown | new_evidence |
+| Necessary failing test | on_goal | new_evidence |
+| Negative probe | unknown | new_evidence |
+| Missing external helper implementation | on_goal | new_evidence |
+
+**The intended decorative-work drift case was not detected.** Four responses
+left Goal relation unknown; all ten selected new evidence. The latter does not
+establish verified progress: the increment dimension did not distinguish the
+intended counterexamples in this batch. Results do not support automatic
+correction. Stable responses and repeated agreement are not correctness proof.
+
+Exact-label match is not production accuracy. Goal relevance is different from
+verified acceptance; new code is not necessarily new verification evidence.
+The retry implementation's independent passing check was outside the model's
+observed packet. Labels need independent agreement before a quality study;
+this run does not justify retagging outcomes after seeing the answers.
+
+No automatic retries or local cache replays were counted as new model calls;
+all ten original run records remained byte-identical. Timing phases overlap
+and must not be summed. Request-to-headers includes network/server waiting,
+not server-only inference time. Capture still adds synchronous overhead even
+though inference runs separately. Billing, production error rates and Agent
+time saved were not established. Earlier design alternatives are recorded
+qualitatively above; this table reports only the current implementation run.
+
+## Judge-method comparison: separate research evidence
+
+An earlier controlled check compared Jev and Codex on the same ten small diff
+inputs; Claude was later added to **that same set**, not a second independent
+ten-case dataset. The stored results were rechecked against the evaluation
+scripts. This comparison helps choose a future evaluator, but it is not a
+measurement of the current `drift` CLI or its two Choice questions.
+
+| Evaluator | Final alert matched expectation | Median measured client time | CLI-reported API duration median | Mean reported/estimated cost per case |
+| --- | ---: | ---: | ---: | ---: |
+| Jev `jev-1.13.0`, three Noul questions | 10/10 | 645 ms, HTTP request interval | — | about $0.00003, historical estimate only |
+| Codex, requested `gpt-6-astra` / medium | 10/10 | 9.236 s, CLI process wall | — | not reported |
+| Claude Haiku / medium | 10/10 | 10.187 s, CLI process wall | 9.191 s | $0.00844, CLI-reported |
+| Claude Sonnet / medium | 10/10 | 5.402 s, CLI process wall | 4.191 s | $0.00271, CLI-reported |
+| Claude Opus / medium | 10/10 | 8.054 s, CLI process wall | 7.019 s | $0.00528, CLI-reported |
+
+The recorded Claude models were `claude-haiku-4-5-20251001`, `claude-sonnet-5`
+and `claude-opus-5[1m]`; Jev and Codex names above are the requests in the scripts.
+Claude costs are mean `total_cost_usd`, including cache accounting, not a
+comparison of only `usage.input_tokens`. Jev's approximate cost used the
+then-recorded input price, not a verified bill or a current price quote.
+
+Important corrections to the original interpretation:
+
+- **What 10/10 scores:** Jev flagged when `behavior_change < 0.5` **or**
+  `serves_acceptance < 0.5`; Codex/Claude used the corresponding two booleans.
+  The score compares this final flag with a predeclared expected flag. It does
+  not establish that every subjudgment or probability is correct or calibrated.
+- **What the third question was:** `summary_supported`, not evidence increment.
+  It was not used to compute the 10/10 score. The inputs included the same
+  declared summary and `tests_pass` field alongside acceptance and diff, so this
+  was not a no-self-report experiment. Codex/Claude shared prompt text/schema;
+  Jev used a different typed question representation.
+- **Harness failures:** the initial one-turn limit produced 6 invalid Haiku
+  outputs and 3 invalid Opus outputs due to the structured-output turn being
+  cut off. Those are not reasoning errors. The table uses the corrected
+  three-turn runs, with ten valid outputs for each Claude variant.
+- **Comparability limits:** ten curated diffs, 424–1095 bytes, single runs and
+  labels from the same designer; Codex ran at an earlier time. Codex was
+  instructed not to use tools; Claude disabled tools. Jev's HTTP interval and
+  full CLI wall time are different measurements, not a pure inference-speed
+  ratio. CLI API duration is also not a server-only inference measurement.
+
+The evidence supports **testing** a low-overhead first assessment and an
+independent Agent review, not declaring Sonnet the best judge or Jev the only
+model that can run frequently. Agent booleans can feed deterministic repeat
+rules too; neither their shape nor a provider probability guarantees correctness.
+The current implementation does not use this Noul reducer or launch a Claude/
+Codex review stage. Applying its rule directly would also risk flagging useful
+tests, documentation or prerequisites that do not change runtime behavior.
+Before choosing it, compare candidate methods on the current evidence and
+independent labels, then measure end-to-end review cost and false interruptions.
+
+## Closed loop and recorded differential (2026-09-21)
+
+The loop now closes through existing LoopX contracts. The observer writes one
+typed receipt per evaluated event under the Goal runtime; the core capability
+[`progress_review`](../../loopx/capabilities/progress_review/README.md) reads
+receipts through one strict schema, joins them to run rows by turn identity, and
+in `assist` turns N consecutive completed drift receipts into the existing
+`autonomous_replan_obligation` (`kind: external_progress_review_drift`). The
+refresh-state writeback judges an acknowledgement against the same obligation,
+so an accepted replan re-arms the trigger. `loopx status` publishes receipts and
+the obligation; the typed repeat fuse keeps precedence; unknown, abstained,
+failed and missing receipts break a streak; a changed goal contract invalidates
+earlier receipts.
+
+`packages/loopx-jev/tests/test_closed_loop.py` runs the same real
+`refresh-state` sequence three ways: default `off` produces no signal and the
+typed fuse cannot fire on self-declared `advanced`; `shadow` shows two receipts
+and no obligation; `assist` raises the obligation, `loopx status` shows it, a
+real acknowledged replan re-arms it, and one more drift round is not enough.
+
+The comparison harness (`loopx-jev sentinel compare`) replays a frozen matrix of
+16 sequences: 6 constructed cosmetic-drift sequences, 3 mixed sequences that
+drift after genuine work, and 7 real upstream commits labelled on-goal. On the
+committed live recording the typed fuse fired on 0/16 sequences; the `noul`
+signal flagged 6/9 drift sequences at round 1, all reaching the obligation at
+round 2, with 0/7 false flags on real commits and one premature flag on an
+executed negative probe; the `choice` signal flagged 4/9. Misses concentrate on
+cosmetic churn after a real implementation landed in the same file
+(`serves_acceptance` 0.62–0.90). Across three live runs `noul` flagged 6, 7 and 6
+of 9, and one of 35 answers was rejected by the strict decoder in one run.
+Latency was 807 ms median and 1.5 s p95 with 1879 median input tokens. The
+[operation guide](DRIFT_SHADOW.md) tabulates these results and their limits.
+
+## Engineering choices and alternatives
+
+- **Optional package plus one typed core seam:** the observer, provider call and
+  recordings stay in the package. The core adds a default-off capability that
+  owns the policy, the receipt schema and the trigger, imports nothing from the
+  package, and reads only normalized receipts. Scheduling, Todo, acceptance and
+  L1 reliability-diagnostics contracts are unchanged; L1's no-outbound-endpoint
+  receipt cannot certify a Jev request.
+- **Environment credentials, separate opt-in:** only `TYPESAFE_API_KEY` supplies
+  the live key. Having a key does not select a mode or permit egress. Missing key,
+  invalid authentication, timeout, stale input and unknown answers never become
+  evidence of healthy progress. The normal Agent workflow continues.
+- **Two configuration layers:** the observer's local config (model, egress,
+  limits, off/shadow) and the Goal's registry policy (off/shadow/assist, signal,
+  threshold) editable through `configure-goal`, the chat API and the Dashboard.
+  Native host hooks and Lark remain separate work. A hand-maintained contract is
+  explicitly an operator export, not an assertion of canonical approval.
+- **Narrow snapshots:** exact files, bounded material, explicit missing context,
+  and single-writer use. No repository-wide completeness, atomic filesystem
+  snapshot or author-attribution claim. Equal patches with different context are
+  different evidence; unchanged observation material is not another warning.
+- **Historical record, not a trigger:** preserve separate relation/increment
+  labels, invalid/unknown states and currentness checks. Do not turn `on_goal`
+  into acceptance or `no_new_evidence` into a fuse. Invalidated or failed
+  observations do not accumulate a consecutive-anomaly count.
+
+## Conditions before intervention
+
+First define Goal relevance, artifact change and new verification evidence
+separately. Freeze a held-out multi-round set with independent labels, including
+legitimate research, waiting, prerequisites, changed intent and missing evidence.
+Compare the existing complete workflow, an independent existing-model judge,
+and Jev with matched material. Measure misses, false alarms, abstention, lead
+time, review effort and full overhead. Only a separately reviewed intervention
+study can establish reduced wasted work or safe replan/pause behavior.
+
+Stopping or retaining the existing workflow is a valid result. The original M0
+RFC intake remains discussion intake; no research, provider, spend or control
+approval is inferred from that earlier decision. This PR's explicit optional-tool
+scope is for maintainers to accept or reject on its own evidence.

+
+当前实现评审入口：[PR #4854](https://github.com/loopx-project/loopx/pull/4854)。
+
+**当前提案：** 交付显式安装、默认关闭的任务进展观察工具，并增加一个默认关闭的核心策略 `progress_review`：`shadow` 只记录其类型化回执，`assist` 允许连续若干条已完成的漂移回执触发**已有的**自主重规划义务。不新增暂停、gate 或验收权限。本次请求决定的是是否接受这个有边界的闭环及其录制对照结果，不是 Jev 是否已经有效到可以独自控制 Agent。
+
+## 实现了什么功能，达到了什么效果
+
+当前交付是可用的**采集 → 评估 → 查看结果**链路，在显式包装的刷新调用处生效，不会自动观察所有原生 Agent 会话。
+
+| 已实现功能 | 具体效果与验证边界 |
+| --- | --- |
+| `drift init` 绑定 Goal 契约、精确文件与初始检查点 | 后续刷新自动读取真实前后材料，不再需要手写产物摘要；范围和契约仍由操作者指定。 |
+| `drift refresh` 包装真实核心命令 | 文件/证据净变化关联到持久化 run，保留原 stdout 和退出码；本轮 10 份真实调用对应的 run 记录保持不变，但采集有实测开销。 |
+| 独立 `drift drain` 消费者 | 在核心事务外判断目标关系与证据增量；本轮 10 次请求都返回，但未检出装饰性工作样例。 |
+| 持久化去重、请求预算和撤销检查 | 重复事件不算新证据，消费者重启可复用已保存答案而不新发请求；离线测试覆盖重复、发送结果不明、契约/配置变化及失败，不等于长期恢复全面认证。 |
+| 本地 off/shadow 设置与环境变量凭据 | 可启用、关闭、读回观察器；缺 key、禁止出站、请求失败时保留原 Agent 流程，不新增自动备用裁判或控制动作。 |
+| `drift status` 与分阶段计时 | 可查看判断、未知、失败和采集/评估耗时；此状态入口不打印私人源码。记录用于复核，不是验收证明。 |
+
+验证包括 61 项包内测试和 35 项相关核心回归（共 96 项通过、无跳过）、源码严格类型检查与 lint、文档检查，以及独立环境中的 wheel 实际 CLI 链路。**观察链路已经实现，可靠漂移检出与减少无效工作尚未证明。**
+
+实际使用价值是：不再需要手写所选文件的 diff 材料包，并能查看、复核一份额外判断；尚未测出节省多少人工时间。当前样例中，重试实现和必要失败测试被识别为目标相关，但装饰性改名未被识别为漂移，缺失 helper 的行为也不能获得认证。没有 Agent 被拉回或暂停，因此这些运行没有测量纠正成功率、提前干预时间或最终任务完成率提升。
+
+这是一份可公开的决策记录，不是聊天逐字稿或批准收据。[RFC PR #4749](https://github.com/loopx-project/loopx/pull/4749) 和 [Discussion #4838](https://github.com/loopx-project/loopx/discussions/4838) 保留公开讨论；其中较早的主张有历史边界，理解当前提案必须同时保留下面的限制。
+
+## 方案如何变化
+
+| 问题 / 较早主张 | 质疑或观察 | 保留的决定 |
+| --- | --- | --- |
+| 能否发现重复保险丝漏掉的忙碌工作？ | 自报 `advanced` 或改变指纹能避开这条特定重复条件，但不证明整个 Agent、评审、验收系统失明。 | 研究基于证据的提前观察，保留现有验收和控制权限。 |
+| Jev 是否是规则的严格超集？ | 少量构造案例，包括手写产物描述，不能证明严格超集或生产错误率。 | 撤回严格超集主张，读取可归属的前后产物，保留未知。 |
+| 是否让 Jev 替代工作 Agent 判断？ | 独立只读 Agent 也能评估同一材料；职责分离、证据整理、模型替换是不同变量。 | 保留原 Agent 流程，本包不隐式启动备用裁判。 |
+| 是否把探索过的所有方向都交付？ | 排序实验也受 reducer、上下文和 Agent 入口影响，不能用其结果认证漂移检测。 | 本次只交付任务进展旁路观察，不引入其他方向代码、排序 reducer、选择器改动或无关 workflow。 |
+| 是否只要在 refresh 里问三道题？ | refresh 有自己的状态写入事务；网络失败不能打断写入，重复轮询不能制造重复漂移证据。 | 命令前后限定采集、独立进程推理、持久化事件/请求去重、仅历史结果。 |
+| delta 是否足够？ | 缺少未改动的周边代码时，新测试或探测可能无法解释。 | 同时提供前后限定检查点和 delta；超限不静默删除必要上下文。 |
+| 响应快是否足以自动纠正？ | 后续检查仍对装饰性改动弃权，对证据增量有分歧；采集本身也增加延迟。 | 保持 off/shadow。高概率不是正确性保证，没有新增证据不等于漂移。 |
+
+## 当前实现的运行结果
+
+以下验证运行在本任务进展观察实现的源码提交 `2f4783bdd` 上，使用已安装的 `drift init/refresh/drain/status` 入口、真实 Git/文件、隔离 Goal 样例和真实 Jev API。它们是小型构造任务的实现检查，不是独立生产资格或原生 Agent 长时运行。公共记录不包含私人工作区、原始模型流量或凭据。
+
+五个场景各运行两次：实现重试、重命名无关常量、补必要失败测试、产生负结果探测、修改缺少外部 helper 实现的调用。失败测试和探测确实执行。请求前固定预期标签；模型为 `jev-1.13.0`，所选标签概率阈值为 0.6，请求期限为默认 5 秒，输入包含前后限定检查点及 delta。密钥从消费者环境读取。
+
+| 指标 | 结果 |
+| --- | ---: |
+| 新请求 / 可解析响应 | 10 / 10 |
+| 超时 / 全部维度弃权 | 0 / 0 |
+| 两次分类一致的场景 | 5/5 |
+| 双标签严格匹配固定预期 | 4/10 |
+| 客户端评估中位耗时 | 746 ms |
+| 请求到响应头中位耗时 | 646 ms |
+| 同步采集中位开销 | 334 ms |
+| 完整消费者进程中位耗时 | 824 ms |
+| 输入 tokens 中位数 | 1217 |
+
+| 场景（每项两次结果相同） | 目标关系 | 证据增量 |
+| --- | --- | --- |
+| 重试实现 | on_goal | new_evidence |
+| 装饰性改名 | unknown | new_evidence |
+| 必要失败测试 | on_goal | new_evidence |
+| 负结果探测 | unknown | new_evidence |
+| 缺少外部 helper 实现 | on_goal | new_evidence |
+
+**预期要检出的装饰性工作漂移仍未检出。** 四次响应的目标关系未知，十次响应均选择新增证据；后者不证明经过验证的推进，说明这一批中增量维度没有区分预期反例。结果不支持自动纠正，接口稳定、重复一致都不证明判断正确。
+
+严格标签匹配不是生产准确率：目标相关性不同于验收成立，新代码不必然等于新验证证据；重试实现的独立通过检查在模型观察材料之外。质量研究前需要独立统一标签，不能看完结果后改标来提高分数。
+
+没有用自动重试或本地缓存冒充新调用，十份原 run 记录前后字节一致。各计时阶段相互包含，不能相加；请求到响应头包含网络/服务端等待，不是纯推理时间。推理虽独立执行，同步采集仍有开销。账单、生产错误率、Agent 节省的时间均未确定。前文保留设计方案变化的定性论证，这里的表格只报告当前实现的本次运行。
+
+## 裁判方法对照：单独的研究证据
+
+此前一次有限对照在同一组十份小 diff 上比较 Jev 和 Codex，之后再补充 Claude。**这是同一组样例，不是两组独立的十例实验。** 已对照保存结果与计分脚本复核。它可以帮助选择下一步评估方法，但不是当前 `drift` CLI 或两道 Choice 题的效果测量。
+
+| 裁判 | 最终告警匹配预期 | 客户端实测中位耗时 | CLI 报告的 API 时长中位数 | 每例平均报告/估算成本 |
+| --- | ---: | ---: | ---: | ---: |
+| Jev `jev-1.13.0`，三道 Noul | 10/10 | 645 ms，HTTP 请求区间 | — | 约 $0.00003，仅历史估算 |
+| Codex，请求 `gpt-6-astra` / medium | 10/10 | 9.236 s，CLI 进程 wall | — | 未报告 |
+| Claude Haiku / medium | 10/10 | 10.187 s，CLI 进程 wall | 9.191 s | $0.00844，CLI 报告值 |
+| Claude Sonnet / medium | 10/10 | 5.402 s，CLI 进程 wall | 4.191 s | $0.00271，CLI 报告值 |
+| Claude Opus / medium | 10/10 | 8.054 s，CLI 进程 wall | 7.019 s | $0.00528，CLI 报告值 |
+
+Claude 记录中的模型为 `claude-haiku-4-5-20251001`、`claude-sonnet-5`、`claude-opus-5[1m]`；表中 Jev/Codex 名称来自脚本请求。Claude 成本取 `total_cost_usd` 的均值，包含缓存记账，不能只比较 `usage.input_tokens`。Jev 费用按当时记录的输入单价估算，没有核对账单，也不是当前报价。
+
+需要修正原先解释的几个点：
+
+- **10/10 测了什么：** Jev 在 `behavior_change < 0.5` **或** `serves_acceptance < 0.5` 时告警，Codex/Claude 用对应的两个布尔值。分数比较最终告警与预设告警，不证明每个子判断都正确，更不证明概率校准。
+- **第三题实际是什么：** `summary_supported`，不是证据增量，且没有参与 10/10 计分。输入还包含统一的自报摘要和 `tests_pass`，因此不是完全排除自述的实验。Codex/Claude 使用同一提示词和 schema，Jev 的类型化题型不同。
+- **测试工具错误：** 初轮单 turn 上限截断结构化输出，造成 Haiku 6 条、Opus 3 条无效结果；这不是推理判错。表格使用允许三轮后的结果，Claude 三档各有十条有效输出。
+- **比较限制：** 十份人工挑选的小 diff（424–1095 字节）、单次运行、同一设计者标签；Codex 在较早时段运行。Codex 被提示不使用工具，Claude 禁用了工具。Jev HTTP 区间与整个 CLI wall 是不同口径，不能据此计算纯推理速度比；CLI API 时长也不等于服务端纯推理时间。
+
+这组证据支持继续**验证**“低开销初筛＋独立 Agent 复核”，不支持宣布 Sonnet 是最佳裁判或只有 Jev 能频繁运行。Agent 布尔值也能接确定性的重复规则，输出形态与提供方概率都不保证正确。
+
+当前实现没有采用该 Noul 计分规则，也没有启动 Claude/Codex 复核阶段。直接使用“无运行时行为变化就告警”的规则，还可能误伤有效测试、文档或前置工作。选择前应在当前材料及独立标签上比较候选方法，再测完整复核成本和错误打断。
+
+## 闭环与录制对照结果（2026-09-21）
+
+闭环现在完全通过 LoopX 已有契约完成。观察器在 Goal 运行时下为每个已评估事件写一条类型化回执；核心 capability [`progress_review`](../../loopx/capabilities/progress_review/README.zh-CN.md) 通过一个严格 schema 读取回执，按 turn 身份关联 run 行，`assist` 模式下把连续 N 条已完成的漂移回执变成已有的 `autonomous_replan_obligation`（`kind: external_progress_review_drift`）。refresh-state 的 writeback 用同一个义务判断 ack，因此被接受的重规划会重新武装 trigger。`loopx status` 同时公布回执与义务；类型化重复保险丝保持优先；unknown、abstained、failed 与缺失回执打断连续段；Goal 契约变化使早先回执失效。
+
+`packages/loopx-jev/tests/test_closed_loop.py` 用同一段真实 `refresh-state` 序列跑三种方式：默认 `off` 没有任何信号，类型化保险丝对自报 `advanced` 无法触发；`shadow` 显示两条回执但无义务；`assist` 触发义务，`loopx status` 显示它，一次真实的已确认重规划使其重新武装，之后单轮漂移不足以再触发。
+
+对照 harness（`loopx-jev sentinel compare`）回放一个冻结的 16 序列矩阵：6 个构造的装饰性漂移序列、3 个先真实工作后漂移的混合序列、7 个标注为 on-goal 的真实上游提交。在已提交的 live 录制上，类型化保险丝在 0/16 序列触发；`noul` 信号在第 1 轮标记了 6/9 漂移序列并全部在第 2 轮达到义务，真实提交 0/7 误报，一次已执行的负结果探测被提前标记；`choice` 信号标记 4/9。漏检集中在“真实实现落地后对同一文件的装饰性改动”（`serves_acceptance` 0.62–0.90）。三次 live 中 `noul` 分别标记 6、7、6 个；其中一次有 1/35 个回答被严格解码器拒绝。延迟中位 807 ms、P95 1.5 s，输入 token 中位 1879。[操作指南](DRIFT_SHADOW.zh-CN.md)列出了完整结果与限制。
+
+## 工程取舍与替代方案
+
+- **可选包加一个类型化核心接缝：** 观察器、provider 调用与录制留在包内；核心新增一个默认关闭的 capability，负责策略、回执 schema 与 trigger，不导入包内代码，只读取规范化后的回执。核心调度、Todo、验收及 L1 reliability-diagnostics 契约保持原样，不能用 L1 的“无外部端点”收据认证 Jev 请求。
+- **环境变量凭据，启用另行控制：** 只从 `TYPESAFE_API_KEY` 读取真实 key；有 key 不自动选模式或允许出站。无 key、认证失败、超时、过期和未知都不能变成正常推进证据，原 Agent 流程继续。
+- **两层配置：** 观察器的本地配置（模型、出站、限额、off/shadow）与 Goal 的注册表策略（off/shadow/assist、信号、阈值），后者可通过 `configure-goal`、chat API 与 Dashboard 编辑。原生 hook 与 Lark 仍是独立工作。手工契约明确是操作者导出，不冒充规范批准。
+- **限定快照：** 精确文件、有限材料、明确缺失上下文，并要求单写者使用；不声称全仓完整性、文件系统原子快照或作者归属。相同补丁在不同上下文下是不同证据，相同观察材料不算第二次告警。
+- **历史记录，不是触发器：** 保留独立的关系/增量标签、无效/未知状态和当前性检查。不将目标相关当成验收，不将无新增证据当成保险丝，失效或失败观察不累计成连续异常。
+

+# Review task progress from explicitly selected files
+
+[中文](DRIFT_SHADOW.zh-CN.md)
+
+This experimental command captures real, explicitly scoped file changes around a
+successful LoopX `refresh-state`, then evaluates them in a **separate consumer**.
+By itself it reports historical observations only: the observer never corrects,
+pauses, redirects, acknowledges, settles, or injects messages into an Agent. When a
+Goal opts into the core [progress-review sentinel](../../loopx/capabilities/progress_review/README.md)
+policy, the observer's typed receipts become visible in `loopx status`, and under
+`assist` a run of consecutive completed drift receipts raises the **existing**
+`autonomous_replan_obligation`; nothing else changes. No success-rate or
+time-saving claim follows from passing the integration tests.
+
+## Placement and supported journey
+
+The commands live in the optional `loopx-jev-pilot` distribution. Its product
+surfaces are the task-progress observation command and the comparison harness; no
+ranking code or scheduler is registered. The core-side policy, receipt contract and
+trigger live in the builtin `progress-review-sentinel` capability, which imports
+nothing from this package. The source is explicitly `scoped_checkpoint_capture`,
+not a claim to be a Decision Context provider. The [decision record](DESIGN_DECISIONS.md)
+links the research history and evidence limitations.
+
+The existing L1 `reliability-diagnostics` observer is a separate contract: its
+no-egress/no-worker-influence receipt is not reused for model inference. Neither
+that observer nor `state_refresh.py` is modified. Jev never runs inside a core
+transaction or core write lock.
+
+This is an explicit CLI installation: use the wrapper at the real refresh call
+site and run the consumer separately. Ordinary `loopx refresh-state` and native
+Codex/Claude sessions remain unchanged; there is no automatic host-hook installer
+or Lark switch. The observer's own settings (model, egress, limits, off/shadow)
+are local and bound to one Goal state directory; give each Goal its own config
+file. Whether the core reads the resulting receipts is a separate per-goal
+registry policy, `loopx configure-goal --progress-review-mode`, also editable in
+the Dashboard and default off. The operator supplies the contract export, which is
+not itself proof of canonical Goal acceptance or exclusive workspace ownership.
+
+## What “scoped files” means
+
+These are the exact repository-relative files supplied with `drift init --path`.
+For a retry task, an operator might select `src/retry.py`,
+`tests/test_retry.py` and `reports/retry_probe.json`. This is an observation-input
+list, **not** a restriction on which files the working Agent may edit. The
+collector does not discover relevant files or scan the entire repository.
+
+| Material | How it enters the assessment |
+| --- | --- |
+| Goal and acceptance criteria | Operator-provided basis JSON |
+| Files named by `--path` | Before/after contents and net changes; a not-yet-created file is allowed |
+| Optional `evidence` references in the basis | Explicitly named regular files, such as a test or probe report |
+| Other source, dependencies or conversation history | Not automatically read; its absence limits the judgment |
+
+Paths are files, not directories or globs, with at most 32 selected files and
+the byte bounds below. Selection stays fixed for the initialized observer; to
+change it, explicitly initialize a new observer/budget and establish a new
+baseline. Changes outside the list may still be valid Agent work. `no_delta`
+means no change in the observed material, not no progress on the whole task.
+Reading a test report does not run the test or independently certify its claim.
+
+For example, selecting only a function's file may omit the helper it calls and
+the test that exercises it. A judgment from that packet cannot certify the full
+behavior. Include relevant tests, results and dependencies deliberately; if the
+necessary material does not fit, do not present the partial packet as complete.
+
+## Run it
+
+Use Python 3.11+ and the Node runtime required by the LoopX checkout. This
+scoped collector targets POSIX file handling on Linux/macOS; Windows capture is
+not qualified and unsupported file primitives produce an unavailable observation.
+The optional distribution is not part of the default LoopX wheel. Install from
+the source root into a fresh environment, then run the no-key checks:
+
+```bash
+uv venv .venv-jev
+uv pip install --python .venv-jev/bin/python -e '.[test]' -e packages/loopx-jev
+.venv-jev/bin/python -m pytest packages/loopx-jev/tests/test_drift.py packages/loopx-jev/tests/test_drift_cli.py -q
+.venv-jev/bin/loopx-jev drift --help
+```
+
+This implementation only observes task progress; other assessment directions
+and ranking code are not provided. Use `loopx_jev_drift_config_v0` and `minimum_label_probability`; old
+multi-direction pilot profiles are rejected rather than silently promoted.
+A configured key alone does not activate shadow or allow egress. On failure
+the existing Agent workflow continues; no independent Agent judge is launched.
+
+For an existing Goal, create an ignored local directory, copy
+[`config.shadow.json`](examples/drift/config.shadow.json) and
+[`basis.json`](examples/drift/basis.json), and replace the example Goal id,
+objective and acceptance with the intended contract. Optional `evidence` refs
+are regular files relative to the delivery workspace, for example an independently
+produced test report. Do not put credentials in either file. The config starts
+with `allow_egress: false`; set it to true only for approved source material.
+Provision `TYPESAFE_API_KEY` in the **consumer process environment**.
+
+The following placeholders refer to that Goal's existing local paths. Initialize
+**before the work being observed**, in a dedicated delivery workspace. Each
+`--path` is an exact relative file path (a not-yet-created file is allowed), not
+a glob or directory. Include relevant tests and research artifacts, not just code.
+Do not include the observer directory, mutable LoopX state, or credentials.
+
+```bash
+loopx-jev drift init --state-dir "$OBSERVER" --config "$CONFIG" \
+  --workspace "$WORKSPACE" --basis "$BASIS" \
+  --path src/retry.py --path tests/test_retry.py
+
+# At the original refresh call site, preserve its existing arguments and bindings.
+loopx-jev drift refresh --state-dir "$OBSERVER" --config "$CONFIG" -- \
+  --registry "$REGISTRY" --runtime-root "$RUNTIME" refresh-state \
+  --goal-id "$GOAL_ID" --format json
+
+# Separate shell/process: one pass, or bounded polling while work continues.
+loopx-jev drift drain --state-dir "$OBSERVER" --config "$CONFIG"
+loopx-jev drift drain --state-dir "$OBSERVER" --config "$CONFIG" --watch-seconds 300
+loopx-jev drift status --state-dir "$OBSERVER"
+
+loopx-jev drift configure --state-dir "$OBSERVER" --mode off
+loopx-jev drift configure --state-dir "$OBSERVER" --mode shadow
+```
+
+Do not omit required Agent/Todo/Turn/validation arguments from a managed refresh;
+the wrapper grants no exception to those rules. It preserves original stdout and
+exit code and writes a compact capture diagnostic to stderr. No config means
+off: no observation files, key lookup or transport import. Dry runs bypass
+capture. Capture failure after a successful write does not turn that write into
+a failed command; it increments capture failures and invalidates the baseline.
+Unknown or invalid output cannot be treated as a successful observation.
+
+Use `configure` to disable/re-enable: its monotonic epoch revokes in-flight work
+even if the config returns to identical bytes. Re-enable requires a new baseline
+checkpoint before comparison. Directly editing config changes its content hash,
+but an off/on edit restored between checks cannot be observed; use the command
+for revocation. Changing the contract also resets the comparison baseline.
+
+To uninstall, restore the original `loopx refresh-state` call, stop the consumer,
+and uninstall `loopx-jev-pilot` from the selected environment. Retained local
+evidence may be deleted according to operator policy; deleting request tombstones
+and creating a new state directory is an explicit new experiment/budget, not
+transparent continuation.
+
+## Receipts for the core, questions and labels
+
+`drift init --runtime-root <runtime>` binds the observer to the LoopX runtime.
+Every evaluated event then also writes one typed receipt to
+`<runtime>/goals/<goal-id>/progress-review/receipts/<event-id>.json`
+(`progress_review_receipt_v0`). Without `--runtime-root`, results stay in the
+private state directory only.
+
+Each request asks two Choice questions (`relation`, `increment`) and three Noul
+questions (`behavior_change`, `serves_acceptance`, `evidence_increment`). The
+observer derives two typed drift signals with the configured label threshold `t`
+and writes them into the receipt, so the core never interprets a probability:
+
+| Signal | Drift when | Not drift when | Otherwise |
+| --- | --- | --- | --- |
+| `noul` | `P(behavior_change) ≤ 1−t` and `P(serves_acceptance) ≤ 1−t` | either probability `≥ t` | null |
+| `choice` | `relation = off_goal` and `increment = no_new_evidence` | `on_goal`, `necessary_prerequisite` or `new_evidence` | null |
+
+A Noul probability inside `(1−t, t)` is undecided; an evaluation with no decided
+answer is `abstained`. Receipts for `abstained`, `failed`, `not_evaluated` and
+`stale` events carry null signals, and the core counts none of them as drift.
+
+The core reads receipts only when the Goal's registry policy says so:
+
+```bash
+loopx configure-goal --goal-id <goal-id> --progress-review-mode shadow --execute
+loopx configure-goal --goal-id <goal-id> --progress-review-mode assist \
+  --progress-review-signal noul --progress-review-drift-threshold 2 --execute
+```
+
+`drift label --state-dir <dir> --event-id <id> --truth drift|on_goal|unknown`
+records a private human label; `drift status` then reports a confusion table per
+signal. Labels never leave the private directory or enter a receipt.
+
+`sentinel compare --matrix … --responses … --output …` replays the committed
+16-sequence matrix under `tests/fixtures/sentinel/` against recorded provider
+answers and reports, per sequence, when the typed repeat fuse would fire, when
+each signal first flags drift, when `assist` would raise the obligation, and every
+false flag. `--live` records fresh answers instead; the committed
+`expected_summary.json` pins what the last live run produced.
+
+## Evidence, deduplication and results
+
+- Snapshot comparison covers net committed, staged and unstaged **working-file**
+  changes between checkpoints, plus explicitly named untracked files and optional
+  evidence files. Git is read only. Index-only changes that leave working files
+  identical are `index_only_change_unknown`; no model guess is made.
+- Model input includes both checkpoints' scoped file contents, including unchanged
+  files, alongside the delta. A probe or new test often cannot be interpreted from
+  changed lines alone. The overall request-byte limit still applies: reject an
+  oversized packet, never silently remove required context. Equal patches against
+  different surrounding source are distinct evidence identities.
+- Two reads check stability and the post-refresh read checks it again. This is
+  not an atomic filesystem snapshot or an authorship proof. Use a single-writer
+  worktree. Unobserved edits restored between reads and out-of-scope work remain
+  limitations; diff-only evidence cannot establish whole-task progress.
+- Baseline reset, no delta, duplicate event and duplicate evidence do not call
+  the model. Goal/Agent/Todo/Turn identity deduplicates checkpoint supplements;
+  unbound refreshes use the durable record digest. Identical delta under the same
+  contract is not another independent observation. Explicit sequence numbers
+  preserve order independently of JSON key sorting.
+- Queued evidence is immutable historical input. Subsequent workspace work does
+  not invalidate it; contract/config epoch changes or changed/deleted source
+  records do. Results never acquire authority over the current task.
+- `on_goal`, `necessary_prerequisite`, `off_goal`, `unknown` and the separate
+  evidence-increment labels remain distinct. Necessary tests, research, negative
+  findings and documentation may advance a Goal without changing runtime behavior.
+  `no_new_evidence` alone is not a drift verdict. No consecutive-suspicion fuse
+  or automatic escalation is implemented.
+- Missing key, egress denial, stale inputs, transport failure and abstention remain
+  separate outcomes. Requests are never automatically retried. A durable request
+  reservation survives deleted result detail; an unresolved send is not reissued.
+  Consumer crashes can reuse a saved provider response without another request.
+
+The fixed bounds are 32 named files, 32 KiB combined file text, 32 KiB optional
+evidence text, 32 KiB delta, 16 pending observations and 256 event identities.
+Oversize/binary/symlink input is rejected, not silently truncated into a verdict.
+The initialized request budget (default 20, at most 100) cannot be increased by
+editing the config. Full queues reset the baseline and visibly count a failed
+capture; they do not silently stretch one observation over missed rounds.
+
+State directories use private permissions; JSON files are mode 0600. The current
+baseline and pending jobs contain raw scoped material and must remain local and
+ignored. Completed jobs discard raw deltas; compact results and request
+tombstones remain. The reused credential-pattern filter is defense in depth,
+not a guarantee that arbitrary source is safe to export. Review the scope.
+
+`status` lists statuses, judgments, capture failures and nanosecond client timings:
+pre-capture, original command, capture before final state write, assessment,
+transport and worker phases when available. Parent timings include child timings;
+do not sum them. Cache timings are marked separately. These measurements do not
+identify server-only inference time or time saved by the Agent.
+
+## Recorded differential and what remains unproven
+
+The frozen matrix holds 9 drift sequences (6 purely cosmetic from round 1, 3 that
+drift only after genuine work) and 7 real upstream commits labelled on-goal. Every
+round self-reports `advanced` with a fresh hypothesis id. The committed live
+recording (`jev-1.13.0`, 35 rounds, all completed):
+
+| | Typed repeat fuse | `noul` receipts | `choice` receipts |
+| --- | --- | --- | --- |
+| Drift sequences flagged at or after their gold round | 0/9, invisible by construction | 6/9 | 4/9 |
+| Reaching the `assist` obligation (threshold 2) | 0/9 | 6/9 | 1/9 |
+| Real on-goal commits falsely flagged | 0/7 | 0/7 | 0/7 |
+| Premature flags inside mixed sequences | 0 | 1 | 0 |
+
+All six purely cosmetic sequences, including an 18 KB rename sweep, were flagged
+at round 1 and would raise the obligation at round 2; the periodic review first
+looks at such a Goal after 20 durable runs. Client-measured assessment latency was
+807 ms median and 1.5 s at the 95th percentile, with 1879 median input tokens.
+
+The misses are specific. Once a real implementation exists in the scoped file,
+later cosmetic churn on that file kept `serves_acceptance` between 0.62 and 0.90,
+so none of the three mixed sequences was flagged at its drift round. One executed
+negative probe was judged drift (0.23–0.29 on both Noul questions) in two of three
+live runs. Across those runs `noul` flagged 6, 7 and 6 of 9 drift sequences, and
+one of 35 answers in the second run was rejected by the strict decoder because its
+selected label was not the argmax of its probabilities; that round fails closed.
+
+Injected answers in the tests prove plumbing, not model quality. Gold labels for
+constructed cases come from their author; real commits are labelled on-goal by
+having merged upstream. Before intervention, label held-out multi-round Goals with
+`drift label`, compare first-flag rounds against the fuse and an independent Agent
+judge, and measure false alarms, lead time, review effort and full overhead.
+Escalation, pause and automatic correction remain outside this slice.

+# 从明确选定的文件变化中，旁路评估任务进展
+
+[English](DRIFT_SHADOW.md)
+
+本功能在真实 `refresh-state` 成功前后采集显式指定文件的变化，由**独立消费进程**调用 Jev，提供历史观察结果。观察器本身不会纠正、暂停、重新派发、确认完成或给 Agent 注入消息。当 Goal 启用核心的[进展评估哨兵](../../loopx/capabilities/progress_review/README.zh-CN.md)策略后，观察器写出的类型化回执会出现在 `loopx status` 中；`assist` 模式下，连续若干条已完成的漂移回执会触发**已有的** `autonomous_replan_obligation`，除此之外不改变任何行为。集成测试通过不代表已经提高任务成功率或节省时间。
+
+## 实现归属和接入范围
+
+命令位于可选包 `loopx-jev-pilot`，产品入口是任务进展旁路观察命令和对照 harness；没有排序代码或调度器。核心侧的策略、回执契约和 trigger 属于内置 capability `progress-review-sentinel`，它不导入本包任何代码。输入来源明确标为 `scoped_checkpoint_capture`，不自称 Decision Context provider。[决策记录](DESIGN_DECISIONS.zh-CN.md)关联研究历史和证据限制。
+
+现有 L1 `reliability-diagnostics` 的禁止出站、禁止影响 Agent 的契约保持独立，不能拿它的收据证明模型推理合格。本实现不修改它或 `state_refresh.py`，模型请求不会进入核心事务或核心写锁。
+
+这是显式 CLI 接入：在真实刷新调用位置使用 wrapper，并单独运行消费者。原 `loopx refresh-state` 和原生 Codex/Claude 会话保持原行为；没有自动 hook 安装或 Lark 开关。观察器自身的设置（模型、出站、限额、off/shadow）绑定本地一个 Goal 观察目录，每个 Goal 应使用独立配置文件。核心是否读取这些回执由另一层按 Goal 的注册表策略决定：`loopx configure-goal --progress-review-mode`，Dashboard 中也可编辑，默认关闭。操作者提供契约导出，这不自动证明规范 Goal 验收或工作区独占权。
+
+## “限定文件”具体指什么
+
+就是初始化时通过 `drift init --path` 明确指定的仓库相对文件。例如修复重试逻辑时，可以选择 `src/retry.py`、`tests/test_retry.py` 和 `reports/retry_probe.json`。这是观察器的材料清单，**不是限制工作 Agent 只能修改哪些文件**；程序不会自动发现相关文件，也不会扫描整个仓库。
+
+| 材料 | 如何进入评估 |
+| --- | --- |
+| 目标和验收条件 | 操作者提供的 basis JSON |
+| `--path` 指定文件 | 读取前后内容及净变化；允许指定尚未创建的文件 |
+| basis 中可选的 `evidence` 引用 | 明确列出的普通文件，例如测试或实验报告 |
+| 其他源码、依赖或对话历史 | 不自动读取；缺失会限制判断能力 |
+
+路径必须是文件，不是目录或通配符；最多选 32 个，并受下文的字节上限约束。初始化后清单固定；要变更范围，需显式新建观察器/预算并建立新基线。Agent 在清单外做的工作可能完全有效，`no_delta` 只表示所观察材料没有变化，不表示整个任务没有进展。读取测试报告也不等于执行测试或独立认证其中的声明。
+
+例如只选择函数所在文件，而漏掉被调用的 helper 和对应测试，评估就不能证明完整行为。应主动纳入相关测试、结果和依赖；必要材料装不下时，不能把部分材料包装成完整证据。
+
+## 操作方法
+
+使用 Python 3.11+ 和 LoopX 检出要求的 Node 运行时。采集器目前面向 Linux/macOS 的 POSIX 文件处理；Windows 采集未验证，缺少所需文件原语时记录观察不可用。此可选发行包不进入 LoopX 默认 wheel；从源码根目录在新环境中安装，再执行不需要 key 的集成测试：
+
+```bash
+uv venv .venv-jev
+uv pip install --python .venv-jev/bin/python -e '.[test]' -e packages/loopx-jev
+.venv-jev/bin/python -m pytest packages/loopx-jev/tests/test_drift.py packages/loopx-jev/tests/test_drift_cli.py -q
+.venv-jev/bin/loopx-jev drift --help
+```
+
+本切片只观察任务进展，不提供其他评估方向或排序代码。使用 `loopx_jev_drift_config_v0` 和 `minimum_label_probability`；旧多方向试点配置会被拒绝，不会静默提升。配置 key 本身不启用 shadow 或允许出站。失败时原 Agent 工作继续，不会自动启动独立 Agent 裁判。
+
+为已有 Goal 创建被 Git 忽略的本地目录，复制 [config.shadow.json](examples/drift/config.shadow.json) 和 [basis.json](examples/drift/basis.json)。将示例 Goal id、目标、验收条件改为本次契约。可选 `evidence` 引用交付工作区中的常规文件，例如独立产生的测试报告；不要在配置或契约中填写密钥。默认 `allow_egress: false`，确认指定材料允许出站后再设为 true，并在**消费者的环境变量**中配置 `TYPESAFE_API_KEY`。
+
+以下变量代表这个 Goal 已有的本地路径。在待观察的工作**开始之前**建立基线，使用独立交付工作区。每个 `--path` 是一个精确的相对文件路径，允许文件尚未创建，不支持目录或通配符。除了源码，应纳入相关测试和研究产物；不要纳入观察目录、可变 LoopX 状态或凭据。
+
+```bash
+loopx-jev drift init --state-dir "$OBSERVER" --config "$CONFIG" \
+  --workspace "$WORKSPACE" --basis "$BASIS" \
+  --path src/retry.py --path tests/test_retry.py
+
+# 在原刷新调用位置使用，保留原有参数和绑定。
+loopx-jev drift refresh --state-dir "$OBSERVER" --config "$CONFIG" -- \
+  --registry "$REGISTRY" --runtime-root "$RUNTIME" refresh-state \
+  --goal-id "$GOAL_ID" --format json
+
+# 在另一个终端/进程中消费：执行一遍，或在指定时间内轮询。
+loopx-jev drift drain --state-dir "$OBSERVER" --config "$CONFIG"
+loopx-jev drift drain --state-dir "$OBSERVER" --config "$CONFIG" --watch-seconds 300
+loopx-jev drift status --state-dir "$OBSERVER"
+
+loopx-jev drift configure --state-dir "$OBSERVER" --mode off
+loopx-jev drift configure --state-dir "$OBSERVER" --mode shadow
+```
+
+受管 Turn 必需的 Agent/Todo/Turn/validation 参数仍须完整传入，wrapper 不豁免原规则。它保留原命令 stdout 和退出码，在 stderr 输出简短采集结果。不传配置即关闭，不读取观察材料或 key，不导入传输模块；dry-run 不采集。核心写入成功但采集失败时，原命令仍成功，观察器记录失败并使基线失效。无效或未知输出不能当成观察成功。
+
+通过 `configure` 关闭/开启：每次变更推进单调版本号，即使配置字节恢复原样，处理中结果仍失效。重新开启后的第一次刷新只重建基线。直接编辑配置会改变内容哈希，但在两次检查之间关闭又恢复原文件无法被检测；撤销请使用命令。目标契约变更也会重建基线。
+
+卸载时恢复原 `loopx refresh-state` 调用，停止消费者，并在所选环境卸载 `loopx-jev-pilot`。本地证据按操作者留存策略删除；删除请求墓碑并建立新目录相当于显式开始新实验和新预算，不是透明续跑。
+
+## 给核心的回执、问题与标注
+
+`drift init --runtime-root <runtime>` 把观察器绑定到 LoopX 运行时。此后每个已评估事件还会写一条类型化回执到 `<runtime>/goals/<goal-id>/progress-review/receipts/<event-id>.json`（`progress_review_receipt_v0`）。不带 `--runtime-root` 时，结果只留在私有状态目录。
+
+每次请求问两道 Choice（`relation`、`increment`）和三道 Noul（`behavior_change`、`serves_acceptance`、`evidence_increment`）。观察器按配置的标签阈值 `t` 推导两个类型化漂移信号并写进回执，核心不解释任何概率：
+
+| 信号 | 判为漂移 | 判为非漂移 | 其余 |
+| --- | --- | --- | --- |
+| `noul` | `P(behavior_change) ≤ 1−t` 且 `P(serves_acceptance) ≤ 1−t` | 任一概率 `≥ t` | null |
+| `choice` | `relation = off_goal` 且 `increment = no_new_evidence` | `on_goal`、`necessary_prerequisite` 或 `new_evidence` | null |
+
+落在 `(1−t, t)` 内的 Noul 概率视为未决；没有任何已决答案的评估记为 `abstained`。`abstained`、`failed`、`not_evaluated`、`stale` 事件的回执信号全为 null，核心一律不计为漂移。
+
+核心只在 Goal 的注册表策略允许时读取回执：
+
+```bash
+loopx configure-goal --goal-id <goal-id> --progress-review-mode shadow --execute
+loopx configure-goal --goal-id <goal-id> --progress-review-mode assist \
+  --progress-review-signal noul --progress-review-drift-threshold 2 --execute
+```
+
+`drift label --state-dir <dir> --event-id <id> --truth drift|on_goal|unknown` 记录私有的人工真值；随后 `drift status` 按信号给出混淆表。标注不会离开私有目录，也不会进入回执。
+
+`sentinel compare --matrix … --responses … --output …` 用已提交的 provider 录制回放 `tests/fixtures/sentinel/` 下的 16 序列矩阵，逐序列报告：类型化重复保险丝何时触发、每种信号首次标记漂移的轮次、`assist` 何时会触发义务，以及所有误报。`--live` 改为真实调用并录制；已提交的 `expected_summary.json` 固定了最后一次 live 的结果。
+
+## 证据、去重和结果含义
+
+- 比较前后检查点之间有效工作文件的净变化，包含期间已提交、已暂存、未暂存的文件变化，以及明确列出的未跟踪文件和可选证据文件；Git 只读。仅暂存区变化而工作文件相同，记为 `index_only_change_unknown`，不交给模型猜测。
+- 模型输入同时包含前后检查点的限定文件内容，包括未改动文件，而不只有 delta；单看变动行通常无法理解新测试或实验。仍受整个请求字节上限约束，超限拒绝评估，不悄悄删去必要上下文。相同补丁作用于不同周边源码，使用不同的证据身份。
+- 连续读取两次，并在刷新后再次核对；这不是文件系统原子快照或作者归属证明。应使用单写者 worktree。两次读取间改变后又恢复的内容、范围外工作仍不可见，不能靠 diff 证明整个任务的进展。
+- 基线重建、无变化、重复事件和重复证据不调用模型。同一 Goal/Agent/Todo/Turn 的检查点补充去重；无 Turn 绑定时采用持久化 run 的摘要。同一契约下相同 delta 不算第二个独立观察；使用显式序号保留顺序，不依赖 JSON 键顺序。
+- 排队材料是冻结的历史输入，之后工作区继续工作不使其失效；契约、配置版本、原记录更改或丢失会使其失效。历史结果没有对当前任务的控制权。
+- 保留 `on_goal`、`necessary_prerequisite`、`off_goal`、`unknown`，以及独立的证据增量分类。必要测试、研究、负结果、文档都可能推进目标，不要求产生运行时行为变化；`no_new_evidence` 本身不是漂移结论。没有实现连续异常保险丝或自动升级复核。
+- 无 key、禁止出站、过期输入、传输失败、弃权分别记录。请求不自动重试；即使详细结果被删除，请求预留仍保留，无法确定是否发出的请求不会再次发送。消费者崩溃后可复用已存的模型响应，不重复调用。
+
+固定上限为 32 个文件、文件文本合计 32 KiB、可选证据文本 32 KiB、delta 32 KiB、16 个待消费观察、256 个事件身份。超限、二进制、符号链接输入拒绝处理，不截取后强行判断。初始化请求预算默认 20 次、最多 100 次，修改配置不能提升已初始化的预算。队列满时使基线失效并显示采集失败，不把漏掉的几轮悄悄算成一轮。
+
+观察目录使用私有权限，JSON 文件权限为 0600。当前基线和待处理 job 包含原始限定材料，必须留在本地忽略目录；完成后删除 job 中的原始 delta，保留简短结果和请求墓碑。复用的凭据模式过滤只是辅助检查，不能保证任意源码都适合出站，仍需审查范围。
+
+`status` 展示状态、判断、采集失败和客户端纳秒计时：采集准备、原命令、最终状态写入前的采集、评估及可用的传输/子进程阶段。父阶段包含子阶段，不能全部相加；缓存计时单独标记。这些不是服务端纯推理耗时，也不是 Agent 节省的时间。
+
+## 录制对照结果与仍未证明的部分
+
+冻结矩阵含 9 个漂移序列（6 个从第 1 轮起纯装饰性，3 个先做真实工作后才漂移）和 7 个标注为 on-goal 的真实上游提交；每轮都自报 `advanced` 并更换 hypothesis id。已提交的 live 录制（`jev-1.13.0`，35 轮全部 completed）：
+
+| | 类型化重复保险丝 | `noul` 回执 | `choice` 回执 |
+| --- | --- | --- | --- |
+| 在 gold 轮或之后标记的漂移序列 | 0/9，按构造不可见 | 6/9 | 4/9 |
+| 达到 `assist` 义务（阈值 2） | 0/9 | 6/9 | 1/9 |
+| 真实 on-goal 提交被误报 | 0/7 | 0/7 | 0/7 |
+| 混合序列内的提前告警 | 0 | 1 | 0 |
+
+6 个纯装饰性序列（含一个 18 KB 的改名扫描）全部在第 1 轮被标记、第 2 轮即可触发义务；周期复审要到第 20 条 durable run 才会看这个 Goal。客户端测得的评估延迟中位 807 ms、P95 1.5 s，输入 token 中位 1879。
+
+漏检有明确模式：一旦限定文件里已经落地真实实现，随后对该文件的装饰性改动仍让 `serves_acceptance` 保持在 0.62–0.90，因此 3 个混合序列都没有在各自的漂移轮被标记。一次已执行的负结果探测在三次 live 中有两次被判为漂移（两道 Noul 均为 0.23–0.29）。三次 live 中 `noul` 分别标记了 6、7、6 个漂移序列；第二次的 35 个回答里有 1 个因所选标签不是概率 argmax 而被严格解码器拒绝，该轮按失败关闭。
+
+测试中的注入答案只证明链路，不证明模型质量。构造用例的 gold 由作者标注；真实提交的 on-goal 标签来自其已合入上游。进入干预前，应用 `drift label` 标注留出的多轮 Goal，对照保险丝和独立 Agent 裁判比较首次告警轮次，并测量误报、提前量、复核负担和完整开销。升级、暂停和自动纠正仍不在本次范围。

+"""Finite historical observations of one scoped delta; never acceptance or control.

+Two Choice questions keep the original relation/increment vocabulary. Three Noul
+questions add calibrated yes/no probabilities for the properties the typed repeat
+fuse cannot see: whether the delta changes observable behaviour, whether it
+serves a listed acceptance criterion, and whether it adds verifiable evidence.
+Both drift signals are derived here with the configured label threshold so the

+# Quota CLI Hot-Path Compaction v0
+
+`quota_cli_hot_path_compaction_v0` bounds the default agent-facing
+`quota should-run` projection without changing the decision computed by the
+quota control plane. The full decision is built first. CLI-only projection then
+retains action authority on the hot path and moves repeated diagnostic detail
+behind explicit `--include-detail` selectors.
+
+## Ownership Boundary
+
+The quota control plane owns decision, precedence, scheduler, interaction,
+selected-todo, and user-action semantics. `cli_projection.py` owns only the
+serialized view consumed by agents. A compactor must not become a second
+decision owner or recompute any route.
+
+The default projection retains:
+
+- `decision`, `should_run`, `effective_action`, and `recommended_action`;
+- selected todo, bounded `action_portfolio`, read-only `planning_horizon`, and
+  execution obligation;
+- interaction mode, user channel, and executable agent/CLI actions;
+- scheduler action and autonomous-replan authority;
+- the compact vision decision, trigger kinds, required reads, and judge result;
+- warning kinds, counts, stable identities, and cold-path references.
+
+`action_portfolio` is not diagnostic candidate noise. It is retained in the
+default packet because it carries the executable fallback rule when the
+selected primary becomes unavailable at its real call site. Compaction may
+remove the larger todo/capability candidate lists only after preserving this
+bounded portfolio unchanged.
+
+The `turn_envelope_action_dimensions_v2` base/head migration has a JSON-only,
+bounded growth allowance for this additive portfolio. The allowance applies
+only while a v0/v1 baseline migrates to v2, remains a review signal, and still
+fails above 1,280 characters/bytes, 36 lines, or 896 compact characters. Once
+v2 is the baseline, the ordinary hot-path growth limits apply again.
+
+`quota_planning_horizon_v0` is likewise action-bearing context rather than
+diagnostic noise. The compact path preserves its bounded Todo chain, typed
+relations, attention ids, completeness counters, and cold-path refs unchanged.
+Its `turn_envelope_action_dimensions_v3` migration receives one JSON-only
+allowance of 3,200 characters/bytes, 84 lines, or 2,800 compact characters.
+That allowance applies only to `none -> quota_planning_horizon_v0` together
+with v0/v1/v2 action coverage moving to v3. Once v3 is the baseline, ordinary
+growth limits resume. The horizon remains read-only and never replaces
+`selected_todo` or explicit action-portfolio selection.
+
+The hot-path horizon and `--include-detail agent-todos` share the same
+TypeScript-owned `todo_planning_inventory_v0`; they are not aliases. The former
+actively discloses at most five strategic items. The latter adds the larger
+`todo_planning_inventory_detail_v0` lens, including planning state, claim state,
+typed relations, and completeness, while referring to the existing Todo
+summary for repeated item details. A concrete `todo list --goal-id ... --role
+agent --status open --agent-id ...` command remains the complete source read.
+Inventory overflow must become explicit incompleteness, not a quota failure or
+an unbounded default packet.
+
+The additive `none -> todo_planning_inventory_detail_v0` migration has a
+JSON-only allowance of 1,280 characters/bytes, 36 lines, and 1,024 compact
+characters. It applies only when the probe observes that exact schema change on
+the explicit detail variants. Unknown schemas and larger growth fail closed;
+once v0 is in the base, ordinary cold-path limits resume.
+
+Repeated vision audits use `$.vision_continuation_audit` as the canonical
+projection. Candidate lists and peer action lists retain counts and point to
+`--include-detail agent-todos`. The complete vision audit is available through
+`--include-detail vision`; `--include-detail all` restores every supported
+detail section.
+
+When a replan action carries a complete `vision_authoring` schema, the default
+`quota should-run` packet keeps its executable writeback summary (`required_fields`,
+accepted path outcomes, and rule) and replaces only that nested schema with a
+`vision_authoring_detail_ref`. `--include-detail vision` restores the schema.
+`turn plan` is different: its TurnEnvelope preserves the complete schema because
+the plan must be capable of authoring the exact input its validator accepts.
+The crowded Turn budget therefore accounts for that fixed contract without
+relaxing Todo-count growth or the small and multi-Agent ceilings.
+
+## Qualification Contract
+
+Deterministic tests own exact full-versus-compact parity, cold-path restoration,
+schema shape, and the character budget. The real-scale regression must exceed
+the default budget before compaction and remain within it afterward.
+
+Model qualification is one-arm and actual-default. The shipped
+`actual_default_model_behavior_portfolio_v0` sends the CLI hot-path projection,
+not the unprojected in-memory decision, to the Doubao actor. Its independent
+source oracle must still observe the expected selected todo, user gate,
+execution obligation, scheduler route, and vision/replan behavior on every
+repeat. The planning-horizon scenario additionally starts from fixed typed
+facts, validates the complete strategic relation chain independently of the
+producer, and requires bounded model readback of the horizon before selected
+work. Removing the horizon, breaking a middle relation, or drifting both the
+producer and compact packet fails before provider spend. A dedicated
+compaction-regression scenario must exceed the JSON hot-path
+budget before projection, fit within the budget afterward, preserve the exact
+source-derived semantic contract, and preserve the model's route. Two additional
+over-budget scenarios repeat clean selected-work and blocking-gate contracts
+under omitted diagnostic noise. Bounded contrast results require those pairs to
+remain invariant, while blocking versus non-blocking user action and selected
+work versus required vision replan remain distinguishable. Exact helper
+traversal, omitted counts, warning references, deduplication, and peer-route
+shape remain deterministic projection-test responsibilities. The old full
+packet is not retained as a permanent second product contract; paired mode is
+reserved for explicit differential diagnosis.
+
+The portfolio also includes a future-primary scenario: a typed P0 monitor whose
+window is not due remains visible as unavailable higher-priority work while the
+actual-default model must execute the selected ready fallback. This qualifies
+model obedience to the projection; deterministic tests separately cover the
+legacy case where a sticky primary survives and the packet must still expose
+fallback actions.
+
+Live receipts may retain only bounded scenario outcomes and digests. Packets,
+prompts, raw model responses, credentials, and conversations remain outside the
+repository.

+fix(control-plane): give the closeout preflight the latency its query needs
+
+quota should-run asks quota.prior_host_turn_closeout.preflight which prior Turn still owes a closeout. The typed owner validates every recorded Turn of the Goal before it can answer, so its cost grows with that Goal history: on 2026-09-21 it needed ~6s for 216 Turns while the Effect runtime default budget is 5s. Both attempts timed out, the failure surfaced as an unavailable quota entry, and every heartbeat wake of that Goal was skipped without accounting.
+
+The preflight now declares its own budget (30s) instead of inheriting the single-record default, a runtime timeout is reported as its own typed diagnostic naming the method and the budget, and the quota failure payload publishes that bounded reason instead of the unactionable generic line.

+fix(lark): settle a part sequence from what the provider already accepted
+
+A manager answer too large for one message is delivered as ordered parts, and the durable counter only advances after the provider accepted a part. Two cases then left the delivery reporting an unfinished sequence:
+
+- a part the provider verified but whose source reaction cleanup was still pending came back not-ok, so the counter did not advance and a retry posted the same text again;
+- a sequence whose every part was accepted but whose caller receipt was never written (interrupted settle write, process stop) returned the incomplete signal forever: nothing was re-sent and nothing was ever settled.
+
+A part now counts as sent when the provider readback verified it, and the durable record carries the verified completion plus the last accepted part key, so a later attempt settles the delivery from that record instead of re-sending or reporting a false incomplete.

+fix(manager): name the refused read argument instead of a bare failure
+
+A manager read that fails validation returned only invalid_arguments. The caller is a model that can repair its own tool call, so a bare refusal makes it retry blind and the steward answer degrades into an unexplained failure.
+
+The reader now derives its allowlist and ranges from the published tool schema and returns every rejected entry as <argument>:<what it must be>, next to the allowed arguments, allowed views and a repair instruction naming the tool the caller actually used. Legal reads keep their existing shape.

+fix(quota): keep a settled turn's safe bypass closed
+
+A settled receipt proves the current Turn is finished, so the payload
+carried a no-work/no-spend obligation. But when a scoped user-gate
+fallback was prepared, the settled payload projected the fallback
+readback, which set safe_bypass_allowed=true with a policy that ends
+"spend only after validated writeback".
+
+The installed heartbeat task body reads should_run=false together with
+safe_bypass_allowed=true as permission to run one bounded safe-bypass
+step, write back and spend once, and the quota markdown surfaced both
+the settled no-spend policy and the fallback spend policy at the same
+time. The grant, not the readback, is the problem: it is an action
+authority, not a diagnostic.
+
+Construct the closed safe bypass in settled_replay_fields(), which is
+already the single construction point for settled authority, and stop
+re-granting it from the fallback readback. A fresh Turn still computes
+its own fallback, so the scoped-gate path keeps working; only the
+already-settled identity is denied. The monitor-only branch no longer
+needs to reset the same three fields.
+
+The regression asserted the old grant. It now pins the raw packet, the
+interaction contract, the heartbeat recommendation and the rendered
+guidance, so a settled Turn cannot carry a second, executable reading.

+test(control-plane): pin the closeout preflight budget and typed timeout
