What

loopx goal-channel prepare-operation maps every ValueError from the typed-operation owner to:

{"ok": false, "blocker": "invalid_configuration", "public_summary": "the Goal Channel configuration is invalid"}

Real causes such as operation executor binding is invalid, operation payload_digest does not match payload, operation projection fields are unavailable or typed operation proposal is unavailable all collapse into that single line, so an operator (or an agent driving the CLI) cannot tell a malformed request from a broken channel binding. Reproduced locally while preparing a typed finance operation: the CLI reported invalid_configuration while the underlying normalizer raised operation executor binding is invalid.

Change

  • Keep the existing blocker and summary for compatibility.
  • Add details.validation_reason: the code-authored ValueError message, truncated at 240 characters.
  • Messages that contain /, \\, ~, control characters or are empty collapse to the exception class name, so private paths never reach the packet.
  • Unit test covering kept reasons and the redaction fallbacks.

Verification

/Users/huangruiteng/Developer/loopx/.venv/bin/python -m pytest tests/extensions/test_lark_goal_channel_operation.py -q
41 passed

No behavior change for successful prepare/deliver/inspect/consume/report paths; the packet only gains a details field on this error branch.

goal-channel prepare-operation mapped every ValueError from the typed
operation owner to blocker=invalid_configuration with a generic summary, so
an operator or agent saw "the Goal Channel configuration is invalid" even
when the real cause was an invalid executor binding or a payload digest
mismatch.

Keep the compatibility blocker and add the code-authored validation reason
through details.validation_reason. Messages that look path-like, carry
control characters, or are unreasonably long collapse to the exception class
so private material never reaches the packet.

Request changes conclusion (author-owned PR; GitHub blocks formal self-review)

[P2] 不要把未知异常文本当作公开安全的校验原因。 准确审查 head:da7b835b844ef524ce7a521ffa931d3753c2eae5。

动机

通过命令行准备待确认操作的用户与 Agent,需要区分请求校验失败和通道配置故障。

例如执行器绑定无效时,旧版只给出笼统的配置错误;新版能显示具体原因,但未知参数名也会未经脱敏进入同一个公开诊断字段。

独立 CLI 验证确认诊断可用,也确认了新增的信息泄露路径;当前版本尚未同时满足可操作错误和公开安全边界。

本次不验证真实飞书发送、金融执行、安装采纳或长期运行收益,也不授予合并权限。

判断依据是修改前的 docs/architecture/rfcs/goal-channel-collaboration-v0.md,revision d4487a7c0a332365fc80ee3ca43d421bdf510d42:Command Contract 要求紧凑、类型化的失败回包;Lark Provider Binding 要求公开状态不暴露私有标识、原始载荷、路径或凭证。需要保留具体诊断的价值,同时证明其可公开,不能由新过滤规则自行定义“安全”。

改动思路

复用现有错误 packet 合理,但公开文本必须由明确的安全原因契约决定;字符黑名单不能承担来源鉴别。

当前 PR 只需修正这一个诊断投影并补 CLI 负例,保留既有操作校验、授权、幂等和成功路径。

数据流是私有请求 → 原操作归一化器 → ValueError → 新 helper → operation_packet.details。旧版在最后一步只显示通用配置错误;新版保留 blocker 和 summary,再增加具体原因。这是有用的、可兼容的方向,不需要新增命令、状态机、配置项或完整 TypeScript 迁移。但原归一化器还会生成带输入内容的错误,不能把所有 ValueError 都视作固定文案。最小修复是复用原错误 owner 的安全原因代码,或在本边界明确允许固定公开原因;其他情况保持通用回退。

具体改动

完整差异只有两个文件,+52/-1。loopx/cli_commands/goal_channel_operation.py 增加 helper,并在共享的 except ValueError 处添加 details.validation_reason。它先 strip,再拒绝空串、超过240字符、斜杠、反斜杠、波浪号和控制字符,其他文本原样返回。PR 描述说超过长度会截断,但实现实际回退到异常类名;应同步描述。

关键代码讲解

_safe_validation_reason(248行)的关键风险在259–269行:这些字符条件只能识别部分文本形状,无法证明消息是固定代码文本。run_goal_channel_operation(272行)把 helper 用在整个 prepare/deliver 分发的 ValueError 分支,因此错误来源不限于作者列出的两个固定例子。其余执行器漂移、发送阶段未知结果、冲突以及普通异常处理保持不变。

未修改的 ChatActionService._allowed_parameters 会执行 raise ValueError(f"unknown typed action parameter: {sorted(unknown)[0]}")。独立使用真实 source console、隔离 File registry、原生安装/启用/doctor 的 bundled provider,向 prepare-operation 送入未知键 api_key=synthetic-review-sentinel:head 的公开 JSON 原样出现 unknown typed action parameter: api_key=synthetic-review-sentinel,同输入在 d4487a7c0a332365fc80ee3ca43d421bdf510d42 只有通用 summary。这里全部是合成标记,没有使用真实凭据,也没有发出飞书消息或创建操作。将键换成含斜杠的名字则正确回退,说明问题正是字符黑名单遗漏动态文本,而非正常拒绝失效。

tests/extensions/test_lark_goal_channel_operation.py 新增 helper 级断言,覆盖固定绑定/摘要错误、路径、换行和空串。整模块41项全部通过,却仍遗漏上述正常 caller 链;请把未知请求字段及 projection 字段的反例放在完整 dispatcher/CLI 边界验证。

对主干的风险

这是即时错误投影变化,没有新增操作授权或持久化格式。四个对照输入在 base/head 都是 exit1、无 actions store、无外部写入;固定执行器绑定和 digest 错误能显示具体原因,provider 关闭时也仍由原 extension_unavailable 门挡住。已有主体绑定、确认、幂等和未知发送结果语义没有被本差异改写。

独立验证:操作测试41 passed/0 skip,Ruff通过,diff advisory后完整 semantic drift smoke通过;标准 native premerge 为6个直接检查加5个选中检查,全部通过、无人工hold,包含真实 CLI 输出预算、维护性、双语RFC和模块边界检查。首次探针误用不存在的 python -m loopx,改为当前 source console;最初 provider-off 结果未当作校验成功,而是在只启用隔离本地 provider 后重做。一次 inventory --check 调用缺少 output 参数,保留该调用并改用文档指定的 semantic smoke。没有修改活动 Goal 或全局安装,也未查询或等待 CI。

剩余风险是新公开字段可进入后续日志、状态或 Agent 上下文,private_provider_payload_captured=false 不会消除已输出的私有请求文本。真实飞书发送、金融执行、用户安装采纳及长期效果均未验证,也不是证明这个本地回归所需的前置条件。

我的整体评价

结论是 REQUEST_CHANGES。具体诊断能减少无效排查,现有 envelope 与 owner 复用也合理;但固定短消息与用户可控消息尚未分开,真实 CLI 已否证当前安全承诺。请修复该局部公开边界并加入上述反例,再针对新准确 head 复评。未来改动的简化检查已应用于这个边界:优先明确安全原因的单一 owner,不再扩充字符黑名单,不要求额外框架或无关迁移。此次不合并、不撤销其他审查,也不把全绿 smoke 当作隐私证明。

English verdict: REQUEST_CHANGES - da7b835b844ef524ce7a521ffa931d3753c2eae5 adds useful diagnostics but reflects an arbitrary unknown request key into public validation_reason. Reproduced through the real isolated CLI against the immutable base; 41 operation tests and native premerge (6 direct + 5 selected) pass but miss this counterexample. Keep safe fixed diagnostics and fall back for untrusted text.

code-authored phrase, and fall back to the exception class otherwise.

[P2] 仅公开明确安全的固定校验原因

New head publishes request-derived text while claiming a public-safe packet; the same base input does not.

最小修复:在既有错误 owner 区分固定公开原因与动态详情;仅输出明确允许的固定消息或类型化安全代码,对未知文本回退,并补完整 CLI 回归。

The [P2] on publishing request-derived text is addressed in #6743 (merged head predates the fix): the packet now carries only a fixed details.validation_reason_code from an allowlist, with unclassified_validation_error as the fallback, plus a full CLI regression.
