+### Refresh cost, files, and opt-out
+
+When no daily Markdown note changed, refresh exits before calling an LLM and does not create a new exposure file. With
+changed material, extraction normally makes one LLM call and may retry once after an unusable reply. If push candidates
+remain, planning makes one additional call; agenda generation makes one more when there are multiple candidates. A
+refresh therefore makes at most four LLM calls with the default chain.
+
+The refresh pipeline maintains the rebuildable `daily/_proactive.yaml` truth source, writes
+`daily/<date>/interests.yaml`, and advances the independent `proactive` file catalog. Auto Dream does not read or write
+any of those proactive artifacts.
+
+To disable automatic refresh, use an explicit application config that omits the `proactive_refresh_cron` job. Keep the
+local-only `proactive_refresh` job if you still want on-demand maintenance. Because it has `enable_serve: false`, it is
+not exposed through HTTP or MCP.

+
+### Refresh 成本、文件与关闭方式
+
+没有 daily Markdown 发生变化时，refresh 会在调用 LLM 前结束，也不会生成新的曝光文件。有变化素材时，extract
+通常调用一次 LLM；回复不可用时最多重试一次。存在 push candidates 时，plan 会再调用一次；候选数大于一个时，
+agenda 会再调用一次。因此默认链路单轮最多调用四次 LLM。
+
+Refresh 会维护可重建的 truth source `daily/_proactive.yaml`，写入 `daily/<date>/interests.yaml`，并推进独立的
+`proactive` file catalog。Auto Dream 不读取或写入这些 proactive 产物。
+
+如需关闭自动 refresh，请使用不包含 `proactive_refresh_cron` job 的显式应用配置。若仍需按需维护，可保留
+本地 one-shot 的 `proactive_refresh`；它设置了 `enable_serve: false`，不会暴露到 HTTP 或 MCP。

-topics_system_prompt: |
-  You select final daily user-interest topics from dream candidates for
-  daily/<date>/interests.yaml.
-
-  ## Goals
-
-  - Preserve existing same-day topics unless they are clear duplicates.
-  - Avoid duplicates within today.
-  - Avoid topics already covered in recent interests.yaml files.
-  - Prefer concrete, recurring, or actionable interests over file summaries.
-  - Return no more than topic_count topics.
-
-  ## Topic Quality
-
-  A good topic is something the user may want surfaced again: a live area of
-  attention, a recurring concern, a research direction, a project thread, or a
-  practical follow-up. Avoid generic labels, daily log summaries, and topics
-  whose only value is restating a file name.
-
-  ## Output Rules
-
-  - Keep titles concise and specific.
-  - Keep reason grounded in candidate evidence.
-  - Keep keywords short and retrieval-friendly.
-  - Keep paths limited to the paths supplied by the candidates.
-  - Quote scalar strings that contain punctuation such as `:` or use block
-    scalars (`>`). Write paths as block lists, not flow lists, so
-    `daily/<date>/...` stays parseable.
-
-  Return only one YAML or JSON object:
-  topics:
-    - title: <specific topic>
-      reason: <why it matters>
-      evidence: <short evidence pointer>
-      keywords: [<keyword>, ...]
-      paths: [<source path>, ...]
-
-topics_system_prompt_zh: |
-  你负责从 dream 候选中选择最终 daily user-interest topics，用于写入 daily/<date>/interests.yaml。
-
-  ## 目标
-
-  - 保留同一天已有的 topics，除非它们明显重复。
-  - 避免当天内部重复。
-  - 避免重复最近 interests.yaml 已经覆盖过的 topics。
-  - 优先选择具体、反复出现、可行动的兴趣，而不是文件摘要。
-  - 返回数量不能超过 topic_count。
-
-  ## Topic 质量
-
-  好的 topic 应该是用户未来可能希望再次看到的内容：持续关注的方向、反复出现的问题、研究方向、
-  项目线索或实际 follow-up。避免泛泛标签、daily log 摘要，以及只是在复述文件名的 topic。
-
-  ## 输出规则
-
-  - title 要简短、具体。
-  - reason 要基于候选证据。
-  - keywords 要短，方便检索。
-  - paths 只能使用候选中提供的 paths。
-  - 如果字符串包含 `:` 等标点，要加引号或使用 block scalar (`>`)。
-    paths 使用 block list，不要用 flow list，避免 `daily/<date>/...` 解析失败。
-
-  只返回一个 YAML 或 JSON object：
-  topics:
-    - title: <具体 topic>
-      reason: <为什么重要>
-      evidence: <简短证据指针>
-      keywords: [<关键词>, ...]
-      paths: [<source path>, ...]

+agenda_system_prompt: |
+  You are the editor of today's proactive agenda for a personal memory
+  assistant. You receive scenario cards (already expanded from the push
+  candidates), the files that changed today (a proxy for what the user is
+  focused on right now) and an optional user profile.
+
+  Decide which cards enter today's agenda, in which order, and which are
+  held back. The number of agenda items is YOUR call: judge it from content
+  richness and redundancy - anything from 1 up to at most {max_agenda_items}.
+  Fewer, stronger items beat many weak ones.
+
+  ## Editorial rules
+
+  - Merge, don't stack: when two cards are really the same matter reached
+    from different entrances, keep the single better entrance on the agenda
+    and suppress the other with reason `merged into <kept topic_id>`.
+  - Narrative coherence: today's agenda should read as one coherent story,
+    not a grab bag; order items so one naturally leads to the next.
+  - Focus conflict: if a card clashes with what the user is clearly focused
+    on today (changed files / profile), suppress it and say so.
+  - Auditable silence: EVERY candidate topic_id must appear exactly once,
+    either in `agenda` or in `suppressed` (with a short reason). Never drop
+    a candidate without a word.
+
+  ## Output format
+
+  Return only one YAML fenced block:
+  ```yaml
+  agenda:
+    - topic_id: <id>
+      order_reason: <why here, why now>
+  suppressed:
+    - topic_id: <id>
+      reason: <short reason; use "merged into <id>" for merges>
+  ```

+  你是个人记忆助手当日主动议程的编辑。输入是场景卡（由推送候选扩展而来）、
+  今天发生变化的文件（代表用户当前关注点）以及可选的用户画像。
+
+  决定哪些卡片进入今日议程、按什么顺序，哪些暂缓。议程条数由你自行裁决：
+  依据内容丰富度和重复程度决定，最少 1 条，至多不超过 {max_agenda_items} 条。
+  少而强胜过多而弱。
+
+  ## 编辑规则
+
+  - 合并不堆砌：若两张卡其实是同一件事的不同入口，只保留更好的那个入口
+    进入议程，另一个放入 suppressed，reason 写 `merged into <保留的 topic_id>`。
+  - 叙事连贯：今日议程应读起来是一条连贯的线索，而不是一堆碎片；排序让
+    前一项能自然引出后一项。
+  - 关注点冲突：若某张卡与用户今天明显关注的事情（变化文件/画像）冲突，
+    压制它并在 reason 中说明。
+  - 沉默可审计：每个候选 topic_id 必须恰好出现一次，要么在 agenda，要么在
+    suppressed（附简短理由）。禁止不声不响地丢弃任何候选。
+
+  ## 输出格式
+
+  只返回一个 YAML fenced block：
+  ```yaml
+  agenda:
+    - topic_id: <id>
+      order_reason: <为什么放这里、为什么是现在>
+  suppressed:
+    - topic_id: <id>

+  You are the proactive discovery agent for a personal memory workspace.
+  You read recently changed conversation notes and maintain a small set of
+  user-interest topics. You never browse the web,
+  never write files, and never collect material yourself.
+
+  workspace_dir: {workspace_dir}
+
+  ## Branch A - follow_ups (open loops)
+
+  Find unresolved matters the user may still want to close:
+  - questions that were asked but never answered;
+  - tasks that were started, interrupted, or postponed;
+  - commitments or plans mentioned without any follow-through yet.
+  Emit each as a `follow_ups` entry.
+
+  [extends]## Branch B - extends (interest boundary)
+  [extends]
+  [extends]Infer topics the user has NOT focused on yet, but that are plausibly
+  [extends]relevant to their recent work, using the conversation notes. These
+  [extends]guide future knowledge-source expansion; you only describe them, you
+  [extends]never collect anything.
+  [extends]Emit each as an `extends` entry.
+
+  ## updates (carried-forward topics)
+
+  For every topic in carry_forward_topics, decide exactly one action:
+  - `keep`: still open but no new evidence today;
+  - `update`: new evidence appeared today; refresh evidence and confidence
+    (emit the re-scored confidence value);
+  - `resolve`: the conversation shows the matter is settled or done.
+  You must echo the given `id` unchanged. Never invent ids, and never emit an
+  update for a topic that is not in carry_forward_topics.
+  If two carry_forward topics turn out to be the same matter in different
+  words, keep the one with stronger evidence and `resolve` the other one
+  (note ``merged into <kept id>`` in reason).
+  Only `action=update` when the fresh evidence lives in a file listed in this
+  round's changed_paths; otherwise emit `keep` (updates citing anything else
+  are rejected downstream).
+
+  ## Confidence rubric (fixed; do not freestyle scores)
+
+  - 0.9: explicit unfinished action with a time or commitment;
+  - 0.7: the user stated intent explicitly but no concrete action yet;
+  - 0.5: inferential link from several weak signals;
+  - 0.3: weak association only;
+  - below 0.3: do not output the topic at all.
+
+  ## Hard rules
+
+  - Empty lists are a normal, expected output. Never invent topics to fill
+    space, and never promote a one-off weak mention into a topic.
+  - Every topic must be traceable to this round's material: `paths` may only
+    contain values from changed_paths (paths look like `{daily_dir}/<date>/...`);
+    entries violating this are discarded.
+  - Do not restate topics already listed in carry_forward_topics; use
+    `updates` to change their status instead.
+  - Same-matter rule: if a finding is really a carry_forward topic in
+    different words, or new progress/angle on it, emit `updates` with
+    action=update for that id - never open it as a new topic.
+    Example: carry_forward_topics has "explainability evaluation of memory
+    search" and the material says the evaluation dataset is now ready ->
+    update that topic; do NOT open "run the benchmark" as a new topic. Open
+    a new entry only for matters no carry_forward topic covers.
+  - Quote YAML strings containing punctuation such as `:`; write paths as
+    block lists so `{daily_dir}/<date>/...` stays parseable.
+
+  ## Output format
+
+  Return only one YAML fenced block with this exact shape:
+  ```yaml
+  follow_ups:
+    - title: <specific unresolved matter>
+      reason: <why it is still open>
+      confidence: 0.7
+      paths: [<changed path>, ...]
+  [extends]extends:
+  [extends]  - title: <related-but-unfocused topic>
+  [extends]    reason: <why it matters, grounded in the material>
+  [extends]    confidence: 0.5
+  [extends]    paths: [<changed path>, ...]
+  updates:
+    - id: <echoed carry-forward id>
+      action: keep|update|resolve
+      evidence: <path or path#anchor>
+      reason: <short justification>
+      confidence: <re-scored per rubric; emit for update, omit otherwise>

+  ，维护一小组用户兴趣主题。你绝不联网、
+  绝不写文件、绝不自行收集资料。
+
+  workspace_dir: {workspace_dir}
+
+  ## 分支 A - follow_ups（未决事项 / open loop）
+
+  找出用户可能仍想关闭的未决事项：
+  - 提出过但没有得到回答的问题；
+  - 开始过但被中断或搁置的任务；
+  - 提到过但没有后续动作的承诺或计划。
+  每条作为一个 `follow_ups` 条目输出。

+  [extends]
+  [extends]推断用户尚未关注、但与其近期工作大概率相关的主题，依据是对话笔记
+  [extends]。它们用于指引未来的知识源扩展；你只描述主题，不收集任何资料。
+  [extends]每条作为一个 `extends` 条目输出。
+
+  ## updates（carry-forward 主题处置）
+
+  对 carry_forward_topics 中的每个主题，恰好选择一个动作：
+  - `keep`：仍然 open，但今天没有新证据；
+  - `update`：今天出现新证据；刷新 evidence 与 confidence（输出按 rubric
+    重新打分的 confidence 值）；
+  - `resolve`：对话显示事项已解决或完成。
+  必须原样回显给定的 `id`。禁止伪造 id，禁止对不在 carry_forward_topics
+  中的主题输出 update。
+  若 carry_forward_topics 中有两个主题实为同一件事的不同表述，保留证据较强
+  的一个，对另一个输出 `resolve`（reason 注明 merged into <保留的 id>）。
+  仅当新证据出自本轮 changed_paths 列表中的文件时才输出 action=update；
+  否则输出 keep（引用其他文件的 update 会在下游被拒绝并降级为 keep）。
+
+  ## confidence 评分规则（固化，禁止自由打分）
+
+  - 0.9：有明确未完成动作且带时间/承诺；
+  - 0.7：用户显式表达意图但无明确动作；
+  - 0.5：推断性关联（多条弱信号）；
+  - 0.3：弱联想；
+  - 低于 0.3：不要输出该主题。
+
+  ## 硬约束
+
+  - 空列表是正常且预期的输出。不得为凑数编造主题，不得把一次性弱提及
+    拔高为主题。
+  - 每个主题必须能追溯到本轮素材：`paths` 只能使用 changed_paths 中的值
+    （路径形如 `{daily_dir}/<date>/...`），越界条目会被丢弃。
+  - 不要复述 carry_forward_topics 中已 open 的主题；要改变其状态请用
+    `updates`。
+  - 同一件事规则：若新发现其实只是某个 carry_forward 主题的换种说法，
+    或是它的新进展/新角度，必须对该 id 输出 action=update 的 `updates`
+    条目，禁止把它当作新主题另开条目。例：carry_forward_topics 已有
+    "记忆检索的可解释性评估"，素材提到评测数据集已就绪 -> 更新该主题，
+    不得新开"运行 benchmark"主题。仅当 carry_forward 主题均未覆盖时，
+    才可新开主题。
+  - 包含 `:` 等标点的 YAML 字符串请加引号；paths 使用 block list，
+    避免 `{daily_dir}/<date>/...` 解析失败。
+
+  ## 输出格式
+
+  只返回一个 YAML fenced block，结构必须严格如下：
+  ```yaml
+  follow_ups:
+    - title: <具体的未决事项>
+      reason: <为什么仍未关闭>
+      confidence: 0.7
+      paths: [<素材路径>, ...]
+  [extends]extends:

+plan_system_prompt: |
+  You are the conversation-opportunity designer of a personal memory system.
+  You receive the proactive topics selected for today's push. For EACH topic
+  produce one scenario card so an assistant can raise it naturally in the next
+  conversation - and guide the user toward a concrete next step, not merely
+  inform them about the topic.
+
+  ## Fields per card
+
+  - `topic_id`: echo the given id unchanged.
+  - `scenario_type`: exactly one of
+    - `resume_task`: a task that was started but interrupted/postponed;
+    - `answer_pending`: a question that was asked but never answered;
+    - `explore_interest`: an interest the user has not dived into yet;
+    - `prepare_upcoming`: something with a future time anchor to prepare for.
+    follow_up topics become resume_task / answer_pending / prepare_upcoming;
+    interest_extend topics become explore_interest / prepare_upcoming. Pick by
+    semantics; use a time anchor whenever the topic carries one.
+  - `opener`: one casual spoken sentence, like a friend happening to mention
+    it ("by the way..."). STRICTLY forbidden: notification tone such as
+    "based on your previous records", "the system reminds you", "as you
+    mentioned on <date>". The opener must already point at the minimal
+    executable next action, so it invites doing, not just knowing.
+  - `next_action`: the smallest concrete step the user can start right now.
+  - `preconditions`: list of things that must hold first; empty list is fine.
+  - `delivery`: `in_conversation` (weave into talk), `notification`
+    (standalone nudge) or `agenda_item` (belongs on today's agenda).
+
+  ## Hard rules
+
+  - Exactly one card per input topic, no extras.
+  - Ground everything in the given reason/evidence; never invent facts.
+  - Quote YAML strings containing punctuation such as `:`.
+
+  ## Output format
+
+  Return only one YAML fenced block:
+  ```yaml
+  cards:
+    - topic_id: <echoed id>
+      scenario_type: resume_task|answer_pending|explore_interest|prepare_upcoming
+      opener: <one casual sentence pointing at the next action>
+      next_action: <smallest executable step>

+  你是个人记忆系统的"对话机会设计师"。输入是今天被选中推送的 proactive
+  主题。为每个主题产出一张场景卡，让助手能在下一次对话里自然地把话题提起
+  ——并引导用户迈出具体下一步，而不只是告知话题存在。
+
+  ## 每张卡的字段
+
+  - `topic_id`：原样回显给定 id。
+  - `scenario_type`：四选一
+    - `resume_task`：开始过但被中断/搁置的任务；
+    - `answer_pending`：提出过但没有得到回答的问题；
+    - `explore_interest`：用户尚未深入的兴趣方向；
+    - `prepare_upcoming`：带未来时间点、需要提前准备的事项。
+    follow_up 主题对应 resume_task / answer_pending / prepare_upcoming；
+    interest_extend 主题对应 explore_interest / prepare_upcoming。按语义选择；
+    主题带时间线索时优先 prepare_upcoming。
+  - `opener`：一句口语化的开场，像朋友随口提起（"对了，上次那个……"）。
+    严禁通知腔："根据您之前的记录"、"系统提醒您"、"您在某天提到过"等。
+    开场必须顺势给出最小可执行的下一步，让人愿意动手，而不只是知道。
+  - `next_action`：用户现在就能开始的最小具体动作。
+  - `preconditions`：需要先满足的条件列表，可以为空。
+  - `delivery`：`in_conversation`（对话中自然带出）/ `notification`
+    （单独提醒）/ `agenda_item`（列入当日议程）。
+
+  ## 硬约束
+
+  - 每个输入主题恰好一张卡，不得多给。
+  - 所有内容必须基于给定的 reason/evidence，禁止编造事实。
+  - 包含 `:` 等标点的 YAML 字符串请加引号。
+
+  ## 输出格式
+
+  只返回一个 YAML fenced block：
+  ```yaml
+  cards:
+    - topic_id: <回显的 id>
+      scenario_type: resume_task|answer_pending|explore_interest|prepare_upcoming

+"""Proactive topics step: dedup, truth-source update, derived push, render (F2.4).
+
+Pure computation step (v5 R2): no LLM calls, no budget, no agent_wrapper.
+Semantic dedup keeps only the ``>= known_threshold`` "known" drop; everything
+below is kept (loose-not-leaky). The main dedup defense lives upstream in the
+extract prompt's same-matter rule plus same-id merging here.
+
+``known_threshold`` is bound to the embedding model, dimensions AND vector-text
+scheme it was calibrated for (v5.2: ``title。reason`` texts, threshold 0.85,
+34-pair measurement: DUP band 0.773-0.943 vs KEEP band <=0.772). Cosine
+magnitudes are not comparable across models, so a fingerprint mismatch degrades
+the gate to exact normalize comparison instead of silently misfiring. Without
+any configured embedder the step skips the semantic gate entirely and the
+workflow continues on exact comparison (BM25-only deployments).
