Closes #2326

问题

当 Replyer 的可见回复被插件清空(例如 MaiLife 的 duplicate_turn / stale_group_turn)时,reply 工具只返回泛化的 plugin_empty_response,Planner 无法得知是插件抑制以及应该改用哪条消息,于是继续对同一旧 msg_id 调用 reply,直到达到内部轮次上限,用户收不到回复。

复现日志(QQ 私聊):

  • 18:27:18 对旧消息 -776958163 的回复已成功发送,MaiLife 同时建立该锚点的轮次锁。
  • 18:27:38 用户发送新消息 1162386407。
  • 18:28:03–18:29:07 Planner 仍用旧 msg_id=-776958163 调用 reply,MaiLife 连续 14 次以 duplicate_turn 抑制。
  • 120s 轮次锁未过期,最终先达到 MAX_INTERNAL_ROUNDS=16,本轮无回复。

修改

  • reply 工具
    • 目标已回复过,且之后出现更新的用户消息时,直接返回 stale_reply_target 结构化失败,并附带 suggested_msg_id,不再生成必被插件拦截的回复。
    • 插件抑制导致的空回复会把 suppress_reason 和最新的 suggested_msg_id 写入工具结果,让 Planner 能看到真实原因。
    • 保留“目标仍是最新消息”时对同一条消息补充回复的提醒逻辑。
  • Replyer:读取 after_response Hook 的 suppress_reason / mai_life_suppress_reason,写入 error_details,并生成可操作的错误信息。
  • Planner:对同一 (msg_id, error_code) 连续两次回复失败时结束本轮思考(reply_failure_limit),避免无意义重试;同批剩余工具调用会收到“未执行”回执。

测试

  • 新增 pytests/maisaka/test_reply_target_guard.py,覆盖旧锚点检测、通知过滤、补充回复保留、失败计数和结束原因。
  • .venv/bin/python -m pytest pytests/maisaka -q:149 passed
  • .venv/bin/python -m ruff check ...:通过

其他信息

  • 本次提交不是 main 分支
  • 已阅读贡献指南
  • 本次更新类型为:BUG 修复
  • 本次更新已经过测试
  • 不涉及 src/A_memorix

不使用无条件自动 retarget,避免破坏合法的“对同一条消息补充回复”场景;只有目标已被回复且之后出现新用户消息时才快速失败。

Summary by CodeRabbit

  • 功能改进
    • 回复目标已过期时,会提示可改用的最新消息,并尝试重新规划;回复失败时也会显示相关原因和建议消息。
    • 首次过期发生在轮次上限时,系统最多额外规划一次;再次遇到过期目标时,会结束本轮。
  • 稳定性改进
    • 系统会记录回复失败情况;同一目标连续失败达到上限后,将停止执行本轮剩余操作。成功回复后,会清除该目标的失败记录。

- reply 工具在目标已回复且其后出现新用户消息时快速返回 stale_reply_target,并给出 suggested_msg_id
- 将插件抑制原因透传到 Planner,失败结果附带 suppress_reason
- Planner 对同一目标连续回复失败两次时结束本轮思考,避免达到内部轮次上限

Walkthrough

生成器和 reply 工具识别过期回复目标,并在失败结果中传递建议消息 ID 或插件抑制原因。推理引擎累计回复失败,按失败次数控制重规划和工具执行,并在符合条件时授予一次额外轮次。

Changes

回复失败处理

Layer / File(s) Summary
传递过期目标与抑制原因
src/common/data_models/reply_generation_data_models.py, src/chat/replyer/maisaka_generator_base.py
新增 ReplyTargetStaleError,保存目标消息 ID、原因和建议消息 ID。生成器捕获该异常,并读取 Hook 返回的插件抑制原因,将相关信息写入失败结果。
校验回复目标并构造失败结果
src/maisaka/builtin_tool/reply.py, pytests/maisaka/test_reply_target_guard.py
reply 工具识别目标回复后出现新用户消息的过期目标,并返回带建议消息 ID 的失败结果。空回复失败可包含插件抑制原因。测试覆盖消息筛选、过期判断和失败字段。
累计失败并控制重规划
src/maisaka/reasoning_engine.py, src/maisaka/display/runtime_mixin.py, pytests/maisaka/test_reply_target_guard.py, pytests/maisaka/test_wait_message_policy.py
推理引擎按目标和错误码累计失败。同一组合失败两次后停止同批剩余工具并以 reply_failure_limit 结束本轮。首次过期失败可追加提醒并重新规划;满足条件时仅授予一次额外轮次。测试覆盖计数、清理、暂停原因和授予条件。

Merge Risk: Minimal · previous review f56b9

The effective round limit is correctly passed to logging. An additional regression test would improve coverage, but no actionable merge-blocking risk is established.

Check name Status Explanation
Title check Passed 标题“fix: 阻止回复旧锚点导致的无效重试”与变更内容直接相关。变更新增 reply 工具的 stale_reply_target 快速失败、插件抑制原因透传、Planner 连续失败结束本轮等机制,目的正是阻止对旧锚点的无效重试。标题简短,类型前缀为 fix,且指出主要影响。

描述覆盖了模板的主要内容:关联 Issue(Closes #2326)、问题背景与复现日志、修改内容、测试结果(pytest 149 通过、ruff 通过)以及其他信息中的分支、贡献指南、更新类型、测试与 src/A_memorix 勾选项。描述未勾选模板第 3 项中的“功能新增”以外的类型,也未填写破坏性更新(第 6 项)。这些是非关键项,或可视为已明确选择 BUG 修复。模板中的 i18n 提醒与 dev 分支提醒未在描述中明确确认。整体基本完整。

Full details: Out of Scope Changes check

Explanation

基于整体 PR 摘要(merge base 8df22f9 至 head f56b9c0)评估,未逐行读取 diff。改动范围包括:src/common/data_models/reply_generation_data_models.py 新增 ReplyTargetStaleError;src/chat/replyer/maisaka_generator_base.py 捕获该异常并返回 stale_reply_target 失败,记录 suppress_reason 写入 error_details;src/maisaka/builtin_tool/reply.py 的过期目标检查、suggested_msg_id 与空回复原因;src/maisaka/reasoning_engine.py 的 (msg_id, error_code) 失败计数、过期目标重规划及一次性额外轮次授权;src/maisaka/display/runtime_mixin.py 的 total_rounds 日志参数;以及 pytests/maisaka 下的新增测试和调用签名更新。额外轮次授权服务于过期目标重规划,属于 PR 声明的 stale 目标处理链路。total_rounds 日志参数用于修正额外轮次后日志显示 17/16 的问题,与该授权直接相关。未发现与 PR 目标无关的改动。剩余不确定性:额外轮次授权的边界条件仅依据摘要判断,未通过 reasoning_engine.py 的代码确认。该不确定性涉及正确性,不影响范围判断。

Full details: Docstring Coverage

Explanation

Docstring coverage is 91.30% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 23 functions across 7 files.

已处理 CodeRabbit 的 3 条意见,提交 55454dc0a:

  1. 补充器路径的旧锚点检查:在 collect_supplement() 确定最终目标后、发送前,用最新聊天记录重新检查该目标;命中 stale_reply_target 时返回带 suggested_msg_id 的失败结果。
  2. 参数错误不再计入目标失败:_record_reply_failure 只统计带非空 msg_id 的回复失败,无效 after_reply、wait_seconds、缺失 reply_reference 等参数错误不会触发熔断,Planner 可修正后重试。
  3. 成功回复后清除计数:新增 _clear_reply_failure_counts,成功回复后清除该目标在所有错误码下的失败计数,避免“失败→成功→再失败”被误判为连续失败。

另外补齐了相关 docstring,pytests/maisaka 152 passed,ruff 通过。

已处理第二轮 CodeRabbit 意见,提交 6ca33510c:

  1. Mai Replier 目标解析前检查:在 resolve_reply_target() 中,补充器确定目标后、模型请求前调用 _build_stale_reply_target_failure;命中过期目标时抛出 ReplyTargetStaleError,由生成器转成 stale_reply_target 结构化失败,避免先生成再丢弃。
  2. 被动模式有限重新规划:_reply_from_planner_content 遇到 stale_reply_target 时,把失败和 suggested_msg_id 写入聊天历史并返回继续本轮;复用现有 _reply_failure_counts 的两次上限,第二次仍过期时以 reply_failure_limit 正常结束,避免无限重试。
  3. 保留生成后检查:生成期间到达新消息导致目标过期时,仍由发送前的检查拦截。

已处理第三轮 CodeRabbit 意见,提交 44b556f8a:

  • 新增 _grant_stale_reply_extra_round:仅在最后一轮首次遇到 stale_reply_target 且失败次数未达两次时,授权一次额外规划轮次。
  • run_loop、_start_cycle_round、_finalize_cycle 使用 _max_internal_rounds + _stale_reply_extra_round_granted 作为有效上限,保证额外轮次一定会被 Planner 读取,且只会多出一轮。
  • 该授权仍在每轮结束时重置,并继续受 _reply_failure_counts 两次上限约束;第二次过期仍以 reply_failure_limit 结束。
