 **Filter execution history through the API**
 
-To inspect failures without downloading every successful occurrence, authenticated clients with `threads:read` can request `GET /api/scheduled-tasks/{task_id}/runs?status=failed&limit=50&offset=0` for an owned task. The optional `status` accepts `queued`, `launching`, `running`, `success`, `failed`, `skipped`, or `interrupted`; these are occurrence statuses, so task statuses such as `completed` are invalid (422).
+To inspect failures without downloading every successful occurrence, authenticated clients with `threads:read` can request `GET /api/scheduled-tasks/{task_id}/runs?status=failed&limit=50&offset=0` for an owned task. The optional `status` accepts `queued`, `launching`, `running`, `success`, `failed`, `skipped`, `interrupted`, or `unmet`; these are occurrence statuses, so task statuses such as `completed` are invalid (422).
 
 Filtering happens before pagination. `limit` (1–200, default 50) and `offset` (nonnegative, default 0) apply to matching records, ordered by creation time then ID, both descending. Omitting `status` preserves the existing mixed-history array response; no matches return `[]`. The API does not change task execution, and the workspace history UI remains unfiltered.
 
 Current MVP limits:
 
-- No conversation-created `schedule_task` tool yet
 - No text-only notification jobs
 - No channel or GitHub dispatch targets (result push above is not a dispatch target)
 
 Enable background polling with `config.yaml -> scheduler.enabled`. Manual trigger uses the same scheduled-task resource and execution path.
 
+### Create schedules in a conversation
+
+Set both `scheduler.enabled: true` and `scheduler.tool_enabled: true`, then restart
+Gateway. An authorized interactive turn can use `schedule_task` to create, list,
+pause or delete tasks belonging to that conversation. For example: “Prepare a
+weekly meeting report every Monday at 9 AM in Asia/Shanghai for four weeks.”
+The tool returns the exact prompt, schedule, optional goal and stop method.
+Recurring report/file jobs may offer a manual trial; the trial requires your
+request and does not count toward the scheduled-launch limit.
+
+New tasks default to a fresh conversation for each occurrence. A configured
+`goal_objective` applies only to that occurrence: success does not stop a
+recurring schedule. The running agent can request `stop_scheduled_task` for its
+own schedule when your overall end condition has been met; the request takes
+effect during terminal finalization. `max_runs` counts automatic launches only,
+and `end_at` provides a deadline. Either end condition takes precedence over a
+pause request. Tool-created sub-hourly schedules require an end condition; each
+owner may keep at most 20 live tool-created tasks, including paused tasks.
+
+An unmet occurrence is recorded as `unmet`, distinct from an execution failure.
+Three eligible automatic unmet occurrences pause a recurring task. Accepted
+success resets the streak, including a success relying on disclosed assumptions;
+manual trials, interruption, execution failure and external waiting do not
+advance it. Resume retains the streak, so another eligible unmet occurrence can
+pause the task again. Existing notification bindings receive goal-unmet and
+auto-pause notices through the same durable outbox; manual trials stay silent.
+
+You can ask the agent in the originating conversation to save an explicit note
+for future runs (at most 10 notes of 500 characters). Fresh recurring runs may
+read the previous executed occurrence through opt-in `read_conversation`, with
+the same owner and read-permission checks. This provides a source reference,
+not an automatic summary or a post-back into the originating chat.
+
+For a trial, send a direct request such as "Run this task now" or "先跑一次".
+The host accepts a bounded set of English/Chinese direct-run requests from the
+current user turn; task mentions, quoted or conditional requests, and a bare
+"yes" do not start a paid run. The agent asks for a direct request when needed.
+
+A goal occurrence can use up to nine agent turns, with an evaluator request after
+each. Evaluator requests and provider-reported tokens are included in run usage;
+missing usage makes the corresponding cost estimate unknown. `token_budget`
+limits the main graph and is checked after model calls; evaluator usage is
+additional, so it is not a strict whole-run or dollar limit.
+
+**Goal evaluation upgrade:** existing scheduled, webhook and autonomous goal
+runs can accept disclosed low-risk, reversible assumptions and record
+`relied_on_assumption` in their verdict. Interactive goal evaluation remains
+strict. This policy also applies when conversation schedule tools are disabled;
+it does not authorize sensitive actions or substitute for user authorization.
+
+
 Scheduled runs use `scheduler.recursion_limit` in `config.yaml` (default `1000`, matching the web UI's interactive budget). Values above `max_recursion_limit` are clamped. This field is read at dispatch, so the next scheduled run picks it up without a Gateway restart.
 
 The background scheduler is single-instance by default. For a multi-pod deployment, set `scheduler.multi_instance: true` and use shared Postgres, `run_ownership.heartbeat_enabled: true`, and `run_events.backend: db`; startup and periodic recovery then preserve live peer runs, atomically return expired launch claims to the queue, take over only expired run leases, and fence stale launch writes. `max_concurrent_runs` is a shared global cap across Pods for `launching`/`running` occurrences; waiting `queued` rows do not consume it. Without those settings, enable the scheduler on exactly one Gateway pod. These scheduler fields are startup-only; restart all Gateway Pods together when changing them.

 筛选先于分页执行。`limit`（1–200，默认 50）和 `offset`（非负整数，默认 0）作用于匹配记录，按创建时间、ID 依次降序排列。不传 `status` 时保留原有的混合历史数组，无匹配项返回 `[]`。此 API 不改变任务执行行为，workspace 历史界面仍展示未筛选的记录。
 
 当前 MVP 限制：
 
-- 暂时还没有可在对话中创建任务的 `schedule_task` 工具
 - 没有纯文本通知任务
 - 没有渠道或 GitHub 分发目标（上面的结果推送不是分发目标）
 
 通过 `config.yaml -> scheduler.enabled` 开启后台轮询。手动触发使用同样的 scheduled-task 资源和执行路径。
 
+### 在对话中创建定时任务
+
+同时设置 `scheduler.enabled: true` 和 `scheduler.tool_enabled: true`，重启
+Gateway 后，具有权限的交互式对话可以通过 `schedule_task` 创建、列出、暂停或
+删除属于该会话的任务。例如：“未来四周，每周一北京时间上午九点准备会议报告。”
+工具回显实际保存的提示词、调度、可选目标和停止方法。周期性报告或文件任务可以
+提出手动试跑，只有用户提出试跑要求才执行，且不计入自动调度次数上限。
+
+新任务默认每次创建独立会话。`goal_objective` 只验证当次执行，达成它不会结束
+周期性调度。运行中的 Agent 在用户的总体结束条件满足后，可以请求
+`stop_scheduled_task` 停止自己的调度，请求在执行终结时生效。`max_runs` 只计算
+自动启动次数，`end_at` 指定结束时间；结束条件优先于暂停请求。工具创建的每小时
+多次调度必须带结束条件，每位用户最多保留 20 个活动工具任务，暂停任务也占名额。
+
+未达目标的执行记为 `unmet`，与执行故障区分。周期任务连续三次符合条件的自动
+执行未达目标后会暂停。成功会重置计数，包括依赖已声明假设的成功；手动试跑、
+中断、执行故障和等待外部条件不递增计数。恢复不重置计数，下一次符合条件的
+未达目标可能再次暂停。目标未达成及自动暂停通知复用现有绑定和持久化 outbox，
+手动试跑不通知。
+
+用户可以在来源会话明确要求保存今后执行的备注，最多 10 条、每条 500 字符。
+新会话中的周期任务可以通过按需开启的 `read_conversation` 回查上一次已执行的
+会话，仍须满足属主和读取权限检查。这是来源引用，不会自动生成记忆，也不会把
+结果回写到来源会话。
+
+试跑时请直接说“先跑一次”或“Run this task now”。宿主只接受本轮用户消息中
+限定的中英文直接执行请求；单独提到任务、引用、条件句或仅回答“好”不会启动
+付费运行。需要时，Agent 会请用户给出直接请求。
+
+一次目标执行最多包含九轮智能体回合，每轮后可以有一次评估器请求。运行用量
+包含评估器请求及服务商返回的 token；缺少用量时，对应费用估算为未知。
+`token_budget` 限制主图，并在模型调用后检查；评估器用量另行计入，因此它
+不是严格的整个运行用量上限，也不是金额上限。
+
+**目标评估升级：** 现有 scheduled、webhook、autonomous 模式的目标运行可以
+接受已声明的低风险、可逆假设，并将 `relied_on_assumption` 记录到评估结果。
+交互式目标评估仍保持严格。即使未启用对话调度工具，此策略也适用；它不授予
+敏感操作权限，也不代替用户授权。
+
+
 定时任务运行会读取 `config.yaml` 中的 `scheduler.recursion_limit`（默认 `1000`，与 Web UI 的交互式预算一致）。超过 `max_recursion_limit` 的值会被截断。该字段在 dispatch 时读取，因此下一次定时运行即可生效，无需重启 Gateway。
 
 后台调度器默认是单实例。多 Pod 部署时，请设置 `scheduler.multi_instance: true`，并使用共享 Postgres、`run_ownership.heartbeat_enabled: true` 和 `run_events.backend: db`；启动和周期性恢复会保留仍由对端持有的运行，把过期的 launch claim 原子退回队列，只接管过期的 run lease，并隔离过期的 launch 写入。`max_concurrent_runs` 是跨 Pod 共享的全局上限，只计入 `launching` / `running` 的执行；等待中的 `queued` 行不占用该配额。没有这些配置时，请只在一个 Gateway Pod 上启用调度器。这些 scheduler 字段只在启动时生效；修改后需要一起重启所有 Gateway Pod。

 run or serialized into run kwargs.
 
+## Scheduled run capabilities and goal outcomes
+
+`RunContext.scheduler_capability` is another per-run host capability. The worker
+installs it under `__scheduler_capability`, rejects caller copies in both context
+carriers, and releases it during terminal cleanup. `scheduled_task_runtime` is a
+separate private occurrence snapshot: its owner, task ID, occurrence ID, and goal
+objective must match the admitted record before the worker may install a goal.
+Run metadata and hidden conversation-reference messages are display data and
+never confer either capability.
+
+A scheduled goal is installed before the first turn, only in a fresh thread,
+using the existing goal writer and default continuation budgets. Terminal
+cleanup clears only that occurrence's goal instance, through the ordinary
+goal lock and expected-checkpoint guard while its own durable run slot is still
+active, before terminal status commits. A process-local scheduled cleanup barrier
+defers local cancel persistence and refuses premature replacement admissions;
+lease renewal continues through this barrier. This scheduled-only exception closes
+the handoff race where a peer could inherit the occurrence's goal. No ORM writer
+transaction spans a checkpointer write. Ordinary user goals retain terminal-first
+completion and delivery cleanup.
+Accepted cancellation during cleanup is applied again after the saver returns,
+including rollback, before terminal persistence; later requests arbitrate through
+the existing durable `cancel_action` compare-and-set.
+
+Scheduled goal `created_at` is the admitted run's timestamp, canonicalized to UTC
+with six microsecond digits. Recovery and ordinary-worker preflight match only an
+exact owner/thread/timestamp/normalized-objective terminal scheduled run, using
+`RunStore.list_by_thread_created_at` without bounded history pagination. Ambiguous
+or unavailable identity fails closed; source metadata must remain server-stamped
+at Gateway admission. `clear_recovered_scheduled_goal` uses the existing idle-thread
+checkpoint-write reservation; a busy thread defers to the next worker's preflight.
+Preflight source-resolution errors stop before graph execution with an explicit
+recovery error and preserve the goal; do not copy idle recovery's catch-and-defer
+behavior into an executing run. Cancellation continues to propagate unchanged.
+Newer user goals and ownership/lease loss always win. Failed cleanup remains
+recoverable through this durable instance tuple without new GoalState fields.
+
+`RunRecord.goal_verdict` / nullable `runs.goal_verdict` preserve the final
+evaluator outcome, including strict boolean `relied_on_assumption`. Persist it
+in the same terminal-status update, including durable cancellation arbitration,
+so recovery need not inspect mutable thread state. All non-interactive policies
+allow disclosed, low-risk reversible assumptions only with achievement evidence;
+their evaluator responses must explicitly provide the assumption boolean.
+
+Goal evaluator usage crosses a JSON-safe sink into
+`RunJournal.record_external_llm_usage_records` before response parsing or observer
+notification can fail. Critic tokens/cache reads and distinct calls belong to
+`middleware:goal_evaluator`; critic responses never enter visible history and
+graph journal callbacks are withheld to prevent double counting. External
+`count_call`/`usage_missing` flags default off for existing subagent consumers;
+missing critic usage adds `missing_usage_calls` to the model bucket, making the
+run's full cost unpriced instead of reporting a partial total as complete.
+Accounting includes critic usage, while the graph token-budget middleware does
+not gate standalone critic calls. A graph token limit is not a strict billing cap.

@@ -44,6 +44,11 @@ Only standalone tool discovery without a model falls back to the base profile.
 The ordinary `task` boundary carries one narrow parent-loop middleware recorder into the isolated subagent runtime under separate loop-detection, tool-promotion, and tool-progress keys. It schedules only `record_middleware` calls back onto the loop that owns `RunJournal`, keeps an execution-local atomic promotion claim so parallel searches do not double-report one new schema, is fenced and drained once before `task` returns, and never exposes the journal or event store to the child loop. Durable batch tasks have no parent run journal and do not use this bridge.
 
 Scheduled-task runtime note:
+- Trial admission matches the entire current user turn against bounded English/Chinese
+  direct-run forms. Bare confirmations, task mentions, quotes and conditional or
+  compound text do not dispatch. Never interpolate titles into authorization text;
+  only fixed commands and opaque task-ID forms are accepted. This host gate is
+  deliberately conservative, not a general intent parser.
 - Scheduled background runs resolve to the `scheduled` interaction policy through trusted `context.non_interactive=true` and therefore exclude `ask_clarification` from the lead-agent tool list. The legacy `context.non_interactive=true` key remains accepted only for internally authenticated scheduler calls during migration; arbitrary HTTP/IM clients cannot set it.
 
 Durable MCP task-management tools are added only while the process-local task submitter is installed. They expose bounded local task fields, including whether cancellation was requested, but never the remote handle. Cancellation records that request durably and returns immediately; the background service owns the remote call and retries. These remain ordinary business tools under an active skill's `allowed-tools` policy and must be declared explicitly.

+# Synthetic scheduled-work Gateway pilot
+
+This runs the production Gateway, scheduler, conversation tools, goal worker,
+sandbox artifact tools and persistence. It does not provide another agent loop.
+All sources and expected artifacts are explicitly synthetic and pinned by the
+committed fixture's SHA-256. No external dataset or network source is fetched.
+
+`plan` is offline. Only an explicit `run-live` starts paid agent work. The runner
+never starts a Gateway, loads credentials, changes models or adds account funds.
+Use a separately started, disposable loopback Gateway, a new `DEER_FLOW_HOME`
+and SQLite directory, empty extension/MCP configuration, and disabled channels,
+memory and automatic titles. Never point it at existing user data.
+
+## Required pilot configuration
+
+The reproduction pilot uses the user's selected official DeepSeek V4.1 Flash
+profile: alias and API model ID `deepseek-flash`, official endpoint
+`https://api.deepseek.com`, non-thinking mode, temperature 0, output cap 1024,
+SDK `max_retries: 0`, normal per-run token budget 60,000, the repository's default
+recursion limit 1000 and request
+timeout 120 seconds. Credentials belong only in the named `DEEPSEEK_API_KEY`
+environment variable of the separately started Gateway.
+
+The normal budget was raised after one pilot occurrence used about 25,000
+tokens to produce and deliver a correct report. Use the same 60,000-token budget
+for both matched arms so that this early threshold does not confound their
+comparison. Provenance records the actual configured budget and the normal
+reference separately; the independent tiny-budget phase remains 1000 tokens.
+
+The configured USD rates are conservative peak estimates: input 0.30 and output
+1.20 per million tokens. The operator checked the
+[official pricing page](https://api-docs.deepseek.com/quick_start/pricing/) for
+this pilot. Provider billing and off-peak/cache discounts are not established by
+the runner. Cost is calculated with production Console `_run_cost` from durable
+`RunRow` usage, using the configured miss price conservatively.
+
+The pilot configuration must include:
+
+```yaml

+  - name: deepseek-flash

+
+The fixture reader is operator-controlled Python configuration. It accepts only
+four committed case IDs and never opens a caller-selected file or URL. Expected
+answers are withheld from its return value. Actual reports use production
+`write_file` and `present_files`, and are opened through the Gateway artifact
+endpoint before an independent JSON/value grade is recorded.
+
+Mark only the disposable database directory after Gateway initialized it:
+
+```bash
+touch "$SCHEDULED_PILOT_SQLITE_DIR/.scheduled-benchmark-disposable"
+```
+
+## Commands
+
+Run from `backend/`, with the exact configuration used by the separately
+started Gateway. Each output directory must be new. Outputs belong in the
+outer workspace's `outputs/scheduler-agent-20261003/`, outside the Git worktree.
+
+```bash
+uv run --no-sync python -m scripts.benchmark.scheduled_tasks plan \
+  --config "$SCHEDULED_PILOT_CONFIG" --model deepseek-flash
+
+uv run --no-sync python -m scripts.benchmark.scheduled_tasks run-live \
+  --config "$SCHEDULED_PILOT_CONFIG" --model deepseek-flash \
+  --base-url http://127.0.0.1:8023 --phase lifecycle \
+  --output "$SCHEDULED_PILOT_OUTPUT/lifecycle" \
+  --max-cost 1 --reserve-per-run 0.08 --timeout 180 --interval 90
+
+uv run --no-sync python -m scripts.benchmark.scheduled_tasks run-live \
+  --config "$SCHEDULED_PILOT_CONFIG" --model deepseek-flash \
+  --base-url http://127.0.0.1:8023 --phase paired \
+  --output "$SCHEDULED_PILOT_OUTPUT/paired" \
+  --max-cost 1 --reserve-per-run 0.08 --timeout 120
+```
+
+For `--phase budget`, deliberately restart/reconfigure the disposable Gateway
+with `token_budget.max_tokens: 1000` and pass that exact new config file. The
+runner requires a tiny budget no greater than 2000, schedules one goal fixture,
+and checks the durable `token_capped` stop or its recorded verdict stand-down
+reason. The public history API projects title/thread-data/messages and omits the
+goal channel. The benchmark reads the same marked disposable SQLite database
+through the production `CheckpointStateAccessor` and native saver with
+`mode=ro` and `query_only=ON`, using the configured full/delta mode and cadence.
+It reads the complete root history, requires zero continuations and counters
+within their recorded limit, checks
+goal cleanup, and observes no later lead-model turn or second occurrence. Missing
+counter evidence fails the phase. It records actual usage, including any one-call
+overshoot. Do not change the model or prices for this phase.
+
+An already recorded tiny-budget run can be rechecked without a Gateway or a
+provider call. Use its exact original configuration and a new output file:
+
+```bash
+uv run --no-sync python -m scripts.benchmark.scheduled_tasks recheck-budget \
+  --config "$SCHEDULED_PILOT_BUDGET_CONFIG" --model deepseek-flash \
+  --run-output "$SCHEDULED_PILOT_OUTPUT/budget-1" \
+  --output "$SCHEDULED_PILOT_OUTPUT/budget-evidence-recheck-v2.json"
+```
+
+The reader is constrained to the disposable default-owner lead assistant and
+base schema without custom/plugin middleware. It preserves the original
+failure/results, matches the actual run's objective, status, calls and usage,
+and labels the new result as a read-only persisted-state recheck of the existing
+real Gateway run. Missing snapshots or counters fail; no zero is fabricated.
+
+The USD 1 admission guard sums all runs in the disposable database, including
+earlier pilot phases, and reserves USD 0.08 before each new run. It polls live
+usage and cancels active pilot work after a guard failure. This is an estimated
+spend guard, **not a hard provider billing limit**: usage becomes visible after
+calls, token budgets can overshoot once, and billing may differ from configured
+rates. The reserve and observed usage are preserved in provenance and results.
+No application-level or provider retries are added by the runner.
+
+## What each phase proves
+
+`lifecycle` creates one schedule through `schedule_task` in a real conversation.
+An automatic fresh-thread occurrence reads the fixture and produces the main
+branch report. The runner pauses between occurrences solely to avoid a note
+timing race, adds the exact user note through the same original conversation,
+then resumes. The second automatic occurrence must read the first through
+`read_conversation`, follow the develop note, write the independently graded
+report and call `stop_scheduled_task`. The runner checks the durable stop-run ID,
+parent paused state, different occurrence threads and no next dispatch. Its
+temporary between-occurrence pause does not count as self-stop evidence.
+An unsuccessful creation or note run, or failed first artifact/source grade,
+fails immediately and cleans up instead of paying for the next stage. A task
+committed by the creation tool is discovered for cleanup even if the surrounding
+interactive run fails. Preserve failed configuration trials separately. A small
+graph recursion budget can stop a correct model response because the middleware
+chain uses many supersteps per turn; the pilot records configuration failures
+without counting them as model loops or implementation defects.
+
+`paired` uses three matched synthetic inputs, with alternating arm order and
+fresh threads. Fixture setup uses production `ScheduledTaskRepository.create`
+and shared Gateway creation validation on one real HTTP-created owner origin
+thread. Both arms carry the same origin binding, sources, prompt, output name,
+model settings and budget; only the goal field differs. This setup bypasses the
+conversation creation step to avoid charging setup-model calls to the study;
+the lifecycle phase independently covers that user-facing step. The real
+Gateway poller and ordinary run worker execute every occurrence.
+
+An alleged goal arm is rejected unless its actual run has goal metadata and a
+durable `goal_verdict`. A plain arm is rejected if either appears. Artifact and
+source-use grades are independent of the evaluator's verdict. Delivery is checked
+separately against the host's `run.delivery` receipt and its successful
+`present_files` path binding; an AI claim or requested tool-call name cannot
+establish delivery. Effective independent completion requires correct artifact
+values, source use, host delivery and successful run status. A subsequent
+`token_capped` stop does not erase verified completion; a capped run without
+delivery remains incomplete. The cap flag, goal verdict and all evidence columns
+are preserved separately for analysis of partial results and evaluator false
+negatives. Results retain
+the raw occurrence status, goal verdict, lead-model turns, total model calls,
+input/output/per-model tokens, peak-price cost estimate and artifact hashes.
+The summary reports each arm descriptively. Three synthetic cases are not a
+statistical or general completion-rate claim, and zero benefit is a valid result.
+
+## Recovery and delivery limits
+
+The lifecycle phase records `restart_recovery: not_exercised_by_this_phase`.
+Testing a crash between durable self-stop and completion needs a separately
+controlled pause/barrier in the disposable agent and a restart of the exact
+Gateway process the operator started. Preserve the stop-request row before the
+crash, then verify recovery pauses the parent, leaves no further dispatch and
+that a repeated completion after user resume cannot pause it again. Offline
+repository/runtime regressions cover this contract; do not relabel them as a
+real-Gateway restart observation.
+
+No provider-account IM delivery is attempted. Writing an outbox row is not
+evidence of receiving a WeCom notification. The runner reports delivery as
+`not_tested` and never reads or messages existing user chats/platform accounts.
+
+Provenance stores config/fixture/prompt hashes, tracked Git diff hash, explicit
+untracked Python/contract/fixture source hashes, model parameters, timestamps,
+timeouts and rates. It never stores credentials, response headers or complete
+provider request payloads. Failures and cleanup failures remain visible, and
+terminal task definitions are preserved. If cleanup cannot pause active work,
+stop the disposable Gateway before leaving it unattended.
