|

A process-local refresh cache makes displayed time depend on state that cannot survive resume or be reconstructed from the durable session. Durable interval scheduling can reduce append frequency without introducing that hidden state.
|
||||
|
||||
Local calendar work also needs to distinguish two authorities: the immutable zone captured by the Session and the zone attached to each browser-originated request. Process state or a mutable connection default cannot represent travel, concurrent tabs, or old headerless Sessions without silently reinterpreting a request.

## Decision
|
||||
|
||||
`@deepseek-ai/dsh-time-context` is an opt-in function plugin in `packages/context/time-context/`. The `context/` group holds bounded request-context enrichments that define neither a tool nor a service, and shipped examples do not mount this plugin because its time-zone disclosure and token cost are deployment policy. It registers a prepended `agent/pre-step` listener and, when a reading is due and the downstream decision enters, returns one additional `UserMessage`. The message carries source `{ kind: 'plugin', plugin: 'time-context' }`; a suppressed, rejected, or failed attempt appends nothing.
|
||||
`@deepseek-ai/dsh-time-context` is an opt-in function plugin in `packages/context/time-context/`. The `context/` group holds bounded request-context enrichments that define neither a tool nor a service. Default compositions leave its disclosure and token cost disabled; the explicit Schedule Web overlay mounts it because local `at` interpretation consumes its authority.
|
||||
|
||||
The listener samples before `step/start`, then settles its reading only in the final enter decision. AgentLoop records it after `step/start` and before request derivation. A downstream rejection or failure therefore prevents the reading from entering durable history.
|
||||
When a reading is due, a prepended `system-prompt/assemble` listener opens a narrow authority envelope in the ordinary next-step inbox. It captures the already-claimed messages, and each user steering insertion admitted during asynchronous assembly synchronously stages a superseding authority. AgentLoop includes non-authority messages inside the closed envelope in the downstream `agent/pre-step` proposal, so ordinary guards, edits, discards, and filtering see the late input.
|
||||
|
||||
The optional `timeZone` config resolves the Node process's IANA zone once at plugin load when omitted; an explicit value is validated by `Intl.DateTimeFormat`. The timestamp includes the numeric UTC offset and resolved IANA zone.
|
||||
After downstream pre-step transformations settle, time-context derives one final authority from the returned messages. An entering step appends those messages and only the final authority after `step/start`, before request derivation. An empty decision consumes the envelope without opening a request. A rejection, throw, or cancellation removes the envelope before the failed turn closes and may settle an already-sampled final authority inside that turn; append rejection drops it instead of leaking it. Disposal removes pending authorities and prevents an in-flight listener from contributing after disposal.
|
||||
|
||||
Each reading's strict source is `{ kind: 'plugin', plugin: 'time-context', authority }`. The authority identifies the proposed turn and step, reports the immutable `SessionHeader.timeZone` as `resolved` or `unavailable`, and folds the final request chain's browser provenance into `resolved`, sorted `mixed`, or `missing`. The rendered clock uses the Session zone when available. A headerless Session uses the configured fallback, or the Node process zone resolved once at plugin load when config is omitted, while its machine Session authority remains `unavailable`. Every explicit or Session-owned IANA zone is validated through `Intl.DateTimeFormat`.
|
||||
|
||||
The optional `refreshIntervalMs` config is manually validated at plugin load as a non-negative safe integer. Omission or `0` injects on every eligible preparation attempt. A positive value scans the raw session events for the most recent `user/message` with this plugin's source and injects when none exists, wall time moved backward, or the event is at least the configured age. The raw event timestamp governs even after compaction shadows the message, so scheduling persists across turns and process resume without a timer or process-local cache.

### Durability and request reconstruction

Each reading remains a normal surface node until compaction shadows it; positive interval scheduling never removes existing readings. A later request therefore sees the cumulative unshadowed readings that affected earlier preparation and steps, rather than a system-prompt value rewritten in place.

Each reading remains a normal surface node until compaction shadows it; positive interval scheduling never removes existing readings. A later request therefore sees the cumulative unshadowed readings that affected earlier preparation and steps, rather than a system-prompt value rewritten in place. The strict source makes the same Session and request-zone authority available to typed consumers such as Schedule without parsing model-facing text.
|
||||
|
||||
The plugin contributes nothing to system-prompt assembly. `request/header` contains no time-context text; request reconstruction obtains the complete durable surface prefix at each `step/start`. Readings and requests need not map one-to-one because interval suppression can enter a request without appending a reading, while rejection or failure appends neither. The plugin depends on the agent registry for its lifecycle listener and does not require the system-prompt service at runtime.
|
||||
The plugin uses system-prompt assembly only as the bounded preparation window; it does not add a system-prompt section. `request/header` contains no time-context text, and request reconstruction obtains the complete durable surface prefix at each `step/start`. Readings and requests need not map one-to-one because interval suppression can enter a request without appending a reading, while a failed no-step preparation may retain its already-sampled authority without transmitting a request.

|
||||
- The first-step duration normally measures from the prompt that opened the turn, while later-step durations measure model and tool processing since the preceding step context.
|
||||
- An omitted `timeZone` still reflects the deployment process rather than a remote user, and elapsed time still uses durable harness append boundaries rather than client-origin timestamps. Supporting client-origin time requires a separate durable input contract.

A reminder created inside a conversation needs to survive a process restart and remain attributable to that exact Session. A process-local timer or model inbox item cannot provide that durability, while a global scheduler or private database would introduce a second identity, persistence, and lifecycle system.

Due work waits until the Agent is fully idle, then enters the ordinary next-turn queue through `followup()`; it never steers the current turn. The separate Web receipt portion of the original design is superseded by [conversational Schedule delivery](../simplification/2026-08-09-conversational-schedule-delivery.md).

### Session log authority and tools
|
||||
|
||||
The version-1 `schedule/change` stream is the only durable Schedule authority. A create record owns a Session-local, non-reused branded id, the trimmed user prompt, the rule, and its UTC target. Delete and dispatch are terminal transitions. The strict decoder and pure fold reject unknown versions, extra fields, reused ids, and transitions against inactive records. A normal Session folds its complete stream; a fork folds only events at or after `SessionHeader.seedLength`.
|
||||
|
||||
The current rule accepts a non-empty prompt and exactly one positive safe-integer `after_seconds`. Its record is `{ id, kind: 'after', prompt, afterSeconds, scheduledAt }`; dispatch stores only the id because the record already fixes its occurrence. `at`, `every_seconds`, `cron`, and `time_zone` are rejected rather than hidden in unused fields. Tool values derive `scheduled` or `overdue` and always include `deliveryMode: 'session-local'`.
|
||||
The current rule union accepts a non-empty prompt and exactly one selector. `after_seconds` is a positive safe-integer delay whose record is `{ id, kind: 'after', prompt, afterSeconds, scheduledAt }`. `at` is either a strict RFC 3339 date-time with `Z` or a numeric offset, or a structured `{ date, time, time_zone? }` local value; its record is `{ id, kind: 'at', prompt, scheduledAt }`. Both dispatch shapes store only the id because the active record already fixes the occurrence. `every_seconds` and `cron` remain rejected rather than hidden in unused fields. Tool values derive `scheduled` or `overdue` and always include `deliveryMode: 'session-local'`.
|
||||
|
||||
An Agent-scoped FIFO serializes each accepted management transaction and the live owner's due transaction from preflight through any post-append barrier. Every tool operation that reads or decides from the fold first awaits `ctx.sessions.flush(session)`. Create may reject input-shape failures before entering the FIFO; after a successful preflight it allocates an id, appends create, and waits for a second barrier. Delete validates its id before the FIFO, then preflights before deciding whether an id is active and waits for a second barrier only when it appends. List and unknown or finished delete never answer from an unconfirmed live suffix or observe a dispatch before their own barrier. A failed barrier returns `persistence_uncertain` rather than guessing whether an eager write committed.

This closes the recovery path where create appended successfully but its post-append barrier rejected: a later list can confirm the retained batch, return the active record, and arm its timer without a Schedule-specific retry loop.

|
||||
|
||||
### Session and request time-zone authority
|
||||
|
||||
The official Web create path requires the browser's IANA zone, validates and canonicalizes it at the Host boundary, and stores it once as immutable `SessionHeader.timeZone`. Resume preserves that value, fork copies it, and another create for the same id and cwd conflicts when its canonical zone differs. Session core keeps the field optional so pre-zone Sessions remain readable but explicitly `unavailable`; a legacy header is never backfilled from a later browser request. JSONL preserves the optional header, while SQLite schema v14 adds nullable `time_zone` and upgrades an owned v13 database atomically without guessing values for existing rows.
|
||||
|
||||
Every Web prompt samples its own `clientTimeZone`, which the Host validates before Agent entry and binds to that immutable `user-rpc` message source. This is request provenance, not a mutable property of the connection or Session, so concurrent tabs cannot overwrite one another and queue, steering, edit, retry, and persisted history retain the originating zone.
|
||||
|
||||
Time-context opens a request-authority envelope at system-prompt assembly. Its model-visible reading uses the Session zone for the current date, local time, and offset, while its machine source names the proposed turn and step plus Session `resolved`/`unavailable` and client `resolved`/`mixed`/`missing` state. Steering admitted during asynchronous assembly is followed synchronously by a same-step superseding authority; the model and Schedule tool both consume the last authority for that turn and step. AgentLoop drains only the closed envelope that begins and ends with those authority messages. If the proposed step exits before `step/start`, it settles appendable authority inside the failed turn or removes authority that cannot be appended, while preserving the existing steering policy, so an old turn/step authority cannot leak into a later request.
|
||||
|
||||
An implicit local `at` is accepted only when the final authority has one resolved client zone equal to the resolved Session zone. A headerless Session, missing or mixed client provenance, or a client/Session mismatch returns `timezone_confirmation_required` with the known zones. An explicit `time_zone` bypasses that ambiguity check but still passes the same IANA validation.
|
||||
|
||||
### Absolute-time normalization
|
||||
|
||||
Schedule, rather than the model or process locale, owns deterministic calendar normalization. Explicit-offset input must match the narrow supported profile and identify a strictly future four-digit-year instant. Structured local input validates the calendar and selected zone, rejects a daylight-saving gap, and chooses the first, earlier instant in an overlap. A successful create stores only UTC `scheduledAt`; the original offset, local fields, and interpreting zone are not a second durable representation. Natural-language interpretation remains the model's job, and time-context appears before the tool call rather than relying on a result echo.
|
||||
|
||||
### Persistence checkpoint and initialization recovery
|
||||
|
||||
`SessionStore.flush()` awaits every scoped listener and treats literal `true` as an explicit durability acknowledgement. An acknowledged call publishes a contained `session/flushed(session, throughSeq)` observation whose exclusive boundary was captured at call entry; append notification itself is not durability evidence. Observe-only listeners return void, an empty or observe-only checkpoint returns `false`, and any listener rejection prevents the success observation after all listeners settle.
|
||||
|
||||
The persistence coordinator supplies that acknowledgement only after its write path is quiescent. Its live controller retains the initial `seedEnd` scalar rather than a seed copy. If the first initialization rejects, a later flush rebuilds that immutable prefix from the append-only Session, reads the backend's actual cursor, and appends only a missing suffix. This covers failures before storage changed and failures reported after a commit, so one transient error neither permanently poisons the Session nor duplicates its prefix.
|
||||
|
||||
### Live delivery lifecycle
|
||||
|
||||
The Agent-scoped owner derives its earliest target from the durable fold. Long targets use bounded timer segments, and every wake reads the wall clock again, so a rollback cannot fire early and a forward jump becomes overdue. If a turn or another maintenance task already owns the Agent, `runMaintenance()` rejects the claim; the record stays active and one `whenIdle()` wait triggers a later retry. A rejected persistence preflight or contained framing or synchronous-enqueue failure also leaves the record active, but no private retry timer runs; later Agent activity reaching idle or a successful Schedule management preflight asks the owner to try again.

|
||||

||||
The accepted path first clears pending persistence and claims the idle phase through `runMaintenance()`. Inside that task it refolds the exact Session suffix, samples the decision clock once, constructs the complete fixed reminder frame with JSON-escaped id and prompt, synchronously queues one `followup()`, and appends the id-only dispatch. Waking input remains parked until maintenance settles, so the driver cannot claim the message before dispatch enters the log; only after the task releases the phase does the owner wait for the dispatch barrier.

The accepted path first clears pending persistence and claims the true idle phase through `runMaintenance()`. Inside that task it refolds the exact Session suffix so a direct management mutation that won the claim race cannot be followed by a stale dispatch, samples the decision clock once, constructs the complete fixed reminder frame with JSON-escaped id and prompt, synchronously queues one `followup()`, and appends the id-only dispatch. Waking input remains parked until maintenance settles, so the driver cannot claim the message before dispatch enters the log; only after the task releases the phase does the owner wait for the dispatch barrier. A framing or synchronous enqueue failure is contained and appends no dispatch. An append failure faults that owner because the message may already be queued. A later prompt-admission, request-checkpoint, or model failure cannot retract a dispatch.

||||

||||
Dispatch records queue admission, not model completion or user receipt. A framing or synchronous enqueue failure appends no dispatch. An append failure faults that owner because the message may already be queued. A later prompt-admission, request-checkpoint, or model failure cannot retract a dispatch. Agent or plugin disposal cancels timers, stops new work, unwinds the three tool registrations, and waits for in-flight preflights or idle waits without deleting durable records.
|
||||
Agent or plugin disposal cancels timers, stops new work, unwinds the three tool registrations, and waits for in-flight preflights or idle waits. It never deletes durable records during teardown. The narrow crash interval after synchronous followup admission and before durable dispatch may repeat the reminder after recovery; the design prefers a visible duplicate over silent loss and makes no model-success, user-read, external-effect, or exactly-once promise.
|
||||
|
||||
### Commit-aware Web receipt
|
||||
|
||||
The Schedule package owns `scheduleReminderPresentation()`, which derives `{ scheduleId, prompt, occurrenceAt }` from create plus dispatch; the client renderer adds the fixed `session-local` label. The current fork's `seedLength` is a hard boundary for child-owned dispatches. An inherited dispatch instead pairs with its nearest preceding same-id create because `session/end-seed` also marks replay or resume construction, not only fork ownership. This keeps resumed ancestor receipts renderable, preserves nested-generation id reuse, and never changes live ownership.
|
||||
|
||||
The Host continues to send every raw event on append. It keeps one monotonic watermark per exact live `Session` in a `WeakMap`; only `session/flushed` advancement makes it redeliver newly covered dispatch events with the generic `{ for: 'event', view }` sidecar. The durable `schedule/change` type selects the client renderer. Taking the maximum contains reversed concurrent flush completion, and exact object identity prevents a reused Session id from inheriting another lifecycle's cursor.
|
||||
|
||||
Attached history independently inspects persistence and adds views only to a stored event prefix whose header identity and every event match the live Session. Persistence canonically writes absent top-level `delegationDepth` as zero, so those two forms are identity-equivalent; cwd, lineage, origin, timestamps, version, id, and every event still match exactly. Missing, failed, divergent, or longer inspection withholds the view while returning raw history. Detached history is already a persisted prefix. A parent dispatch copied into a fork seed therefore appears in child history only after child storage proves that prefix.
|
||||
|
||||
The browser Session accepts a repeated seq only when the durable event is deeply identical, then upgrades the sidecar immediately without appending another event. Tail loading and true gap repair retain uncovered events in the existing `liveBuffer`; an accepted repair snapshot starts another pull when it advanced the tail but left a later buffered gap, while an identity conflict triggers a full resync. Ordinary older-page pagination keeps receiving live tail events in the current arrays, while a sidecar below the current window stays with the in-flight page and attaches only when that page returns the identical event. Reconnect generations prevent stale page or repair results and `finally` blocks from touching the rebuilt window. `TranscriptAdapter` creates a generic `PresentedEventNode` keyed by the durable event type. `ui-conversation` dispatches it through `conversation.chat.eventview` and retains an expandable JSON fallback, while `ui-schedule` owns the bilingual `schedule/change` reminder row.

||||

**Store reminders in a private SQLite table or global scheduler.** This could run cold Sessions, but requires a second Session identity map, startup scan, ownership lease, crash protocol, and notification policy. The accepted scope deliberately runs only while the original Session is live.
|
||||
|
||||
**Claim dispatch before `followup()` or add exactly-once fencing.** A claim-first record can silently lose the user-visible reminder when enqueue fails. Cross-process exactly-once requires a lease, outbox, acknowledgement, and downstream idempotency boundary that Session-local best-effort model work does not provide.

**Treat the model message as the receipt.** The queued inbox item is process-local and may fail before a durable user message exists. A dispatch-derived Web receipt remains visible and replayable independently of model success.
|
||||
|
||||
**Attach the reminder view on append.** `session/event` precedes the durability result, so this would display a ghost receipt after a rejected flush. The success watermark makes presentation follow the commit point.
|
||||
|
||||
**Add a Schedule-specific wire frame, client cache, or management page.** The generic event sidecar, existing Session window buffer, keyed slot, and model-facing tools already carry the required result. A parallel transport or state store would duplicate identity and replay logic.
|
||||
|
||||
**Adopt existing roots or register global tools.** Late adoption makes plugin load order change which unseen timers begin running and exposes tools outside the supported root-Agent composition. Future-root, Agent-scoped installation gives one clear lifecycle.
|
||||
|
||||
**Use the process zone or the most recently connected browser as the default.** The process zone is deployment state, while a connection-level value lets one tab or a later trip silently reinterpret another request. An immutable Session default plus message-bound client provenance makes disagreement visible without creating shared mutable zone state.
|
||||
|
||||
**Parse arbitrary natural-language dates inside Schedule or persist the local input.** A second language parser would compete with the model, and retaining local text or zone beside the resolved instant would create two durable interpretations of one one-shot target. The model emits a narrow structure after seeing time-context; Schedule validates it and stores one UTC fact.
|
||||
|
||||
The design does not recognize or migrate any unmerged Schedule implementation or private storage format. No fixed Session id, claim-before-send record, startup miss, or private database is a compatibility input.
|
||||
|
||||
## Verification
|
||||
|
||||
Package tests pin strict decoding, transitions, fork suffixes, id reuse, time bounds, bounded waits, wall-clock movement, overdue admission, fixed framing, enqueue and append failures, barrier recovery, registration rollback, and quiescent disposal. A production-JSONL restart test resumes one overdue record through the real Agent lifecycle and proves that a later restart does not dispatch it again. The opt-in Loader composition boots the package, and a keyless browser scenario executes `schedule_create` through the complete tool pipeline and snapshots the ordinary assistant follow-up.
|
||||
Package tests pin strict decoding, transitions, fork suffixes, id reuse, offset and local-calendar profiles, IANA validation, gap rejection, overlap-first selection, mismatch confirmation, time bounds, bounded waits, wall-clock movement, overdue admission, fixed framing, enqueue and append failures, barrier recovery, registration rollback, and quiescent disposal at 100% per-file coverage. Persistence tests cover new, fork, and resumed initialization failures against the actual durable cursor, optional header round-trips, a real SQLite v13-to-v14 migration, and a production JSONL restart. The assembled Loader/Web restart lane proves pending recovery, fork isolation, one durable dispatch, cold-history rendering without Agent activation, and no redelivery after another restart. Host/client tests cover zone identity across live, stored, and concurrent-create paths; per-operation prompt provenance; commit gating; reversed watermarks; semantic header identity; per-event prefix matching; same-seq upgrades; every window merge exit; and reconnect generations.
|
||||
|
||||
Time-context and AgentLoop lifecycle tests cover queued, edited, discarded, cancelled, and retried input; mixed tabs; delayed assembly with late steering; pre-step hook, assembly, checkpoint, append, and disposal failures; same-step last-authority selection; and non-leakage into the next turn. The opt-in Loader composition boots the source and built packages. Keyless real-browser scenarios execute `schedule_create` through the complete tool pipeline for the existing short `after` case and one absolute-time case, observe the identity-matched persisted prefix, and render the durable reminder card from attached history. The deliberately absent model adapter closes the turn with an error after dispatch, proving that model failure does not remove the receipt.
|
||||
|
||||
## Consequences
|
||||
|
||||
- Reminder state survives process restart and replays through ordinary Session persistence without a new database or public service.
|
||||
- A cold Session does no work and sends no external notification; reopening it may deliver an overdue reminder.
|
||||
- Each live root adds only fold-derived timers, an optional idle wait, and one in-flight operation.
|
||||
- The narrow crash interval after synchronous follow-up admission and before durable dispatch can repeat the reminder after recovery; the design prefers a visible duplicate over silent loss and makes no exactly-once promise.
|
||||
- The strict after-only protocol is intentionally small; other rule families require explicit record, time, and recurrence semantics rather than dormant fields.
|
||||
- A cold Session does no work and sends no external notification; reopening it may deliver an overdue reminder, and every tool/card says `session-local`.
|
||||
- Each live root adds only fold-derived timers, an optional idle wait, and one in-flight operation. Long waits and plugin unload do not create a second durable state machine.
|
||||
- A Session's default zone is immutable and may remain unavailable for older history. Travel or concurrent tabs can therefore require an explicit zone instead of silently changing the meaning of “tomorrow at 09:00.”
|
||||
- The generic commit-aware event-view path is reusable by other durable events, but it adds event-identity checks and generation-aware merge behavior to the client Session window.
|
||||
- The strict one-shot protocol covers delayed and absolute targets. Recurring rule families still require explicit transition, catch-up, and model-budget semantics rather than dormant fields.

### Session 日志权威与工具
|
||||
|
||||
版本 1 `schedule/change` stream 是唯一持久 Schedule 权威。create record 拥有 Session 内不复用的品牌 id、trim 后的用户 prompt、规则与 UTC 目标。delete 和 dispatch 是终结 transition。严格 decoder 与 pure fold 会拒绝未知版本、额外字段、重复 id，以及针对非活动 record 的 transition。普通 Session 折叠完整 stream；fork 只折叠 `SessionHeader.seedLength` 位置及其后的 event。
|
||||
|
||||
当前规则接受非空 prompt 与恰好一个正 safe-integer `after_seconds`。record 形状是 `{ id, kind: 'after', prompt, afterSeconds, scheduledAt }`；dispatch 只保存 id，因为 record 已经唯一确定 occurrence。`at`、`every_seconds`、`cron` 与 `time_zone` 会被拒绝，不会作为未使用字段隐藏在协议中。工具 value 派生 `scheduled` 或 `overdue`，并始终包含 `deliveryMode: 'session-local'`。
|
||||
当前规则 union 接受非空提示词与恰好一个 selector。`after_seconds` 是正 safe-integer delay，其 record 为 `{ id, kind: 'after', prompt, afterSeconds, scheduledAt }`。`at` 可以是带 `Z` 或数字 offset 的严格 RFC 3339 date-time，也可以是结构化的 `{ date, time, time_zone? }` local value；其 record 为 `{ id, kind: 'at', prompt, scheduledAt }`。两种 dispatch shape 都只保存 id，因为活动 record 已经唯一确定 occurrence。`every_seconds` 与 `cron` 仍会被拒绝，不会作为未使用字段隐藏在协议中。工具 value 派生 `scheduled` 或 `overdue`，并始终包含 `deliveryMode: 'session-local'`。
|
||||
|
||||
一个 Agent-scoped FIFO 会将每项已接纳的管理事务与 live owner 的到期事务从 preflight 到任何 post-append barrier 全程串行化。每项从 fold 读取或作出判断的工具操作都会先等待 `ctx.sessions.flush(session)`。create 可以在进入 FIFO 前拒绝只依赖输入 shape 的失败；preflight 成功后才分配 id、追加 create，并等待第二个 barrier。delete 在进入 FIFO 前验证其 id，随后在判断 id 是否活动前先 preflight，只有实际追加时才等待第二个 barrier。list 与未知或已终结 delete 绝不会从未确认的 live 后缀作答，也不会在自身的 barrier 前观察到 dispatch。barrier 失败会返回 `persistence_uncertain`，而不是猜测 eager write 是否已经提交。
|
||||
|
||||
每次成功的管理 preflight 也会要求 live owner 重新计算。这闭合了 create 已成功追加、但 post-append barrier 拒绝时的恢复路径：后续 list 可以确认保留的 batch、返回活动 record，并在没有 Schedule 私有重试循环的情况下 arm timer。

||||

|
||||
|
||||
### Session 与请求时区权威
|
||||
|
||||
官方 Web create 路径要求浏览器提供 IANA 时区，在 Host 边界校验并规范化后，将其一次性存为不可变的 `SessionHeader.timeZone`。resume 保留该值，fork 复制该值；若针对相同 id 与 cwd 的另一次 create 得到的规范化时区不同，则发生冲突。Session core 保持该字段可选，使时区支持前的 Session 仍可读取，但其时区明确为 `unavailable`；绝不会用后续浏览器请求回填 legacy header。JSONL 保留该可选 header；SQLite schema v14 增加 nullable `time_zone`，并以原子方式升级自有 v13 数据库，不为既有行猜测值。
|
||||
|
||||
每条 Web 提示词都会单独采样自己的 `clientTimeZone`；Host 在进入 Agent 前校验该值，并把它绑定到不可变的 `user-rpc` 消息来源。它是请求 provenance，而不是连接或 Session 的可变属性，因此并发 tab 无法相互覆盖，排队、steering（中途引导）、编辑、重试和持久化 history 都会保留来源时区。
|
||||
|
||||
Time-context 在系统提示词组装时打开请求权威包络。它向模型显示的读数按照 Session 时区给出当前日期、本地时间和 offset；机器源则标明拟议的轮次与步骤，以及 Session 的 `resolved`／`unavailable` 状态和 client 的 `resolved`／`mixed`／`missing` 状态。异步组装期间获准进入的 steering 后面，会同步追加同一步骤的取代权威；模型与 Schedule 工具都使用该轮次和步骤的最后一条权威。AgentLoop 只排空以这些权威消息为首尾的闭合包络。如果拟议步骤在 `step/start` 前退出，AgentLoop 会在失败轮次内结算可追加的权威消息，或移除无法追加的权威消息，同时保留既有 steering 政策，从而防止旧轮次／步骤的权威泄漏到后续请求。
|
||||
|
||||
只有最终权威包含一个已解析的 client 时区，且它等于已解析的 Session 时区，才会接受隐式 local `at`。无 header 的 Session、client provenance 缺失或 mixed，或 client／Session 不匹配，都会返回 `timezone_confirmation_required` 及已知时区。显式 `time_zone` 可绕过这项歧义检查，但仍要通过相同的 IANA 校验。
|
||||
|
||||
### 绝对时间规范化
|
||||
|
||||
确定性的日历规范化由 Schedule 负责，而不是模型或进程 locale。显式 offset 输入必须匹配受支持的窄 profile，并标识一个严格位于未来、年份为四位数的时点。结构化 local 输入会校验日历和选定时区，拒绝夏令时空档，并选择重叠时段中首次出现的较早时点。成功的 create 只存储 UTC `scheduledAt`；原 offset、local 字段和用于解释的时区不会形成第二份持久表示。自然语言解释仍由模型完成，time-context 出现在工具调用之前，而不依赖结果回显。
|
||||
|
||||
### Persistence checkpoint 与初始化恢复
|
||||
|
||||
`SessionStore.flush()` 会等待所有 scoped listener，并把字面量 `true` 视为显式 durability acknowledgement。获得确认的调用会发布受包含的 `session/flushed(session, throughSeq)` observation；其中排他边界在调用入口捕获，append 通知本身不是 durability 证据。仅观察 listener 返回 void；空或只有观察者的 checkpoint 返回 `false`；任一 listener 拒绝都会在全部结算后阻止成功 observation。
|
||||
|
||||
persistence coordinator 只有在写路径完全停稳后才给出该确认。live controller 只保留初始 `seedEnd` 标量，不复制 seed。首次初始化拒绝后，后续 flush 会从仅追加 Session 重建该不可变前缀、读取后端实际 cursor，并只追加缺失 suffix。无论失败发生在存储变更前，还是提交后才返回拒绝，一次暂时性错误都不会永久毒化 Session 或重复写入其前缀。
|
||||
|
||||
### Live 交付生命周期
|
||||
|
||||
Agent-scoped owner 从持久 fold 派生最早目标。超长目标使用有界 timer 分段，每次 wake 都重新读取墙钟，因此回拨不会提前触发，前跳则会形成 overdue。如果 agent 已被某个轮次或另一项 maintenance task 占用，`runMaintenance()` 会拒绝此次认领；record 保持活动，并由一个 `whenIdle()` wait 触发稍后的重试。被拒绝的 persistence preflight 或被收容的 framing／同步入队失败同样会让 record 保持活动，但不会运行私有重试 timer；后续 agent 活动进入 idle，或成功的 Schedule 管理 preflight 会要求 owner 再次尝试。
|
||||
|
||||
获得准入的路径会先清空 pending persistence，并通过 `runMaintenance()` 认领 idle phase。该任务会重新折叠确切的 Session 后缀，只采样一次 decision clock，使用 JSON-escaped id 与 prompt 构造完整固定 reminder frame，同步排入一次 `followup()`，再追加只含 id 的 dispatch。触发唤醒的 input 会保持 parked，直到 maintenance 结束，因此 driver 无法在 dispatch 进入 log 前认领消息；只有该任务释放 phase 后，owner 才会等待 dispatch barrier。
|
||||
获得准入的路径会先清空 pending persistence，并通过 `runMaintenance()` 认领真正的 idle phase。该任务会重新折叠确切的 Session 后缀，从而确保在认领竞态中胜出的直接管理变更之后不会跟随陈旧 dispatch；随后只采样一次 decision clock，使用 JSON-escaped id 与 prompt 构造完整固定 reminder frame，同步排入一次 `followup()`，再追加只含 id 的 dispatch。触发唤醒的 input 会保持 parked，直到 maintenance 结束，因此 driver 无法在 dispatch 进入 log 前认领消息；只有该任务释放 phase 后，owner 才会等待 dispatch barrier。framing 或同步入队失败会被收容，且不会追加 dispatch。append 失败会使该 owner fault，因为消息可能已经入队。后续 prompt admission、request checkpoint 或模型失败都不能撤回 dispatch。
|
||||
|
||||
dispatch 记录的是队列准入，而不是模型完成或用户收到提醒。framing 构造或同步入队失败不会追加 dispatch。append 失败会使该 owner fault，因为消息可能已经入队。后续 prompt admission、request checkpoint 或模型失败都不能撤回 dispatch。Agent 或插件 dispose 会取消 timer、停止新工作、撤销三个工具注册，并等待进行中的 preflight 或 idle wait，且不会删除持久 record。
|
||||
Agent 或插件 dispose 会取消 timer、停止新工作、撤销三个工具注册，并等待进行中的 preflight 或 idle wait。teardown 绝不会删除持久 record。同步 followup 获得准入后、durable dispatch 前的狭窄崩溃窗口可能在恢复后重复提醒；本设计选择可见重复而非静默丢失，不承诺模型成功、用户阅读、外部副作用或 exactly-once。
|
||||
|
||||
### Commit-aware Web 回执
|
||||
|
||||
Schedule package 拥有 `scheduleReminderPresentation()`，从 create 加 dispatch 派生 `{ scheduleId, prompt, occurrenceAt }`。client renderer 会添加固定的 `session-local` 标签。当前 fork 的 `seedLength` 是 child 自有 dispatch 的硬边界。继承的 dispatch 则会与它之前最近的同 id create 配对，因为 `session/end-seed` 也会标记回放或恢复构造，而不仅标记 fork 所有权。这使恢复后的祖先回执仍可渲染，保留嵌套 generation 的 id 复用，并且绝不会改变 live ownership。
|
||||
|
||||
Host 在 append 时继续发送所有 raw event。它在 `WeakMap` 中按 exact live `Session` 保存一个单调 watermark；只有 `session/flushed` 前进时，才会用通用 `{ for: 'event', view }` sidecar 重投新覆盖的 dispatch event。持久 `schedule/change` 类型用于选择 client renderer。取最大值可以收容反序完成的并发 flush，按对象身份键控则阻止复用的 Session id 继承另一个生命周期的 cursor。
|
||||
|
||||
已附加 history 会独立 inspect persistence，只有 stored event prefix 的 header identity 与每个 event 都和 live Session 匹配时才添加 view。persistence 会把顶层缺失的 `delegationDepth` 规范写成零，因此两种形式在身份上等价；cwd、lineage、origin、时间戳、版本、id 与每个 event 仍必须精确匹配。inspect 缺失、失败、分歧或比 live 更长时，只会省略 view，raw history 仍然返回。已分离 history 本身就是持久前缀。因此复制进 fork seed 的 parent dispatch 只有在 child storage 证明该前缀后才会显示。
|
||||
|
||||
浏览器 Session 只有在 durable event 深度一致时才接受重复 seq，随后立即升级 sidecar，不再追加 event。只有尾部加载与真正的 gap repair 才会将尚未覆盖的事件保留在既有 `liveBuffer` 中；已接受的 repair 快照在推进 tail 但仍留下后续已缓冲的 gap 时会启动另一次 pull，身份冲突则会触发全量重新同步。普通旧页分页会让当前数组继续接收 live tail 事件，当前 window 以下的 sidecar 则由 in-flight page 自身暂存，只有该页返回身份完全相同的事件时才附着。重连 generation 会阻止陈旧的 page 或 repair 结果以及 `finally` 块触碰重建后的 window。`TranscriptAdapter` 创建按持久事件类型键控的通用 `PresentedEventNode`。`ui-conversation` 通过 `conversation.chat.eventview` 分发，并保留可展开 JSON fallback；`ui-schedule` 则拥有双语 `schedule/change` 提醒行。
|
||||
|
||||
```text
|
||||
schedule_create → Session create event → persistence
|
||||

## 已考虑的替代方案
|
||||
|
||||
**使用 `ctx.tasks`。** Task 拥有进程内工作、终态结果、收集与通知语义，而不是 Session 日志状态和对话 follow-up。复用它会让错误的生命周期成为权威。
|
||||
**使用 `ctx.tasks`。** Task 拥有进程内工作、终态结果、收集与通知语义，而不是 Session 日志状态和可回放会话回执。复用它会让错误的生命周期成为权威。
|
||||
|
||||
**把提醒存入私有 SQLite 表或全局 scheduler。** 这样可以运行 cold Session，却必须增加第二套 Session 身份映射、startup 扫描、ownership lease、崩溃协议与通知政策。当前范围有意只在原 Session live 时运行。
|
||||
|
||||
**在 `followup()` 前 claim dispatch，或增加 exactly-once fencing。** claim-first record 会在入队失败时静默丢失用户可见提醒。跨进程 exactly-once 需要 lease、outbox、acknowledgement 与下游幂等边界，而 Session-local best-effort 模型工作不具备这些边界。
|
||||
|
||||
**把模型消息当作回执。** 已排队 inbox 项是进程内状态，可能在产生持久 user message 前失败。从 dispatch 派生的 Web 回执不依赖模型成功，仍然可见、可回放。
|
||||
|
||||
**在 append 时附加提醒 view。** `session/event` 早于 durability 结果；这样会在 flush 拒绝后显示幽灵回执。成功 watermark 让 presentation 服从提交点。
|
||||
|
||||
**增加 Schedule 专属 wire frame、client cache 或管理页面。** 通用 event sidecar、既有 Session window buffer、键控 slot 与面向模型工具已经能承载所需结果。平行 transport 或状态 store 会重复身份与回放逻辑。
|
||||
|
||||
**接管既有根或注册全局工具。** 晚接管会让插件加载顺序改变哪些不可见 timer 开始运行，并把工具暴露到支持范围之外。只面向未来根、按 Agent scope 安装，提供了单一明确生命周期。
|
||||
|
||||
**将进程时区或最近连接的浏览器用作默认值。** 进程时区属于部署状态，而连接级值会让某个 tab 或后续出行悄然重新解释另一个请求。不可变的 Session 默认值加上绑定到消息的 client provenance，能让分歧显现，而不创建共享的可变时区状态。
|
||||
|
||||
**在 Schedule 内解析任意自然语言日期，或持久化 local 输入。** 另一套语言解析器会与模型竞争，而在已解析时点旁保留 local 文本或时区，会为同一个一次性目标形成两种持久解释。模型看到 time-context 后输出一个窄结构；Schedule 校验它并存储一个 UTC 事实。
|
||||
|
||||
本设计不会识别或迁移任何未合入的 Schedule 实现或私有存储格式。固定 Session id、claim-before-send record、startup miss 与私有数据库都不是兼容输入。
|
||||
|
||||
## 验证
|
||||
|
||||
package 测试固定严格 decoding、transition、fork suffix、id 不复用、时间边界、有界等待、墙钟变化、overdue 准入、固定 framing、入队与 append 失败、barrier 恢复、注册 rollback 和完全停稳 dispose。production JSONL restart 测试通过真实 Agent 生命周期恢复一条 overdue record，并证明后续再次 restart 不会重复 dispatch。显式启用的 Loader 组合可启动该 package，无密钥浏览器场景会通过完整工具 pipeline 执行 `schedule_create`，并为普通 assistant follow-up 生成快照。
|
||||
package 测试以逐文件 100% coverage 固定严格 decoding、transition、fork suffix、id 不复用、offset 与 local-calendar profile、IANA 校验、gap 拒绝、overlap-first 选择、mismatch confirmation、时间边界、有界等待、墙钟变化、overdue 准入、固定 framing、入队与 append 失败、barrier 恢复、注册 rollback 和完全停稳 dispose。persistence 测试依据实际 durable cursor 覆盖 new、fork 与 resumed 初始化失败、可选 header round-trip、一次真实 SQLite v13 到 v14 migration，以及 production JSONL restart。组装后的 Loader/Web restart lane 证明 pending 恢复、fork 隔离、单次 durable dispatch、无需激活 agent 的 cold-history rendering，以及再次 restart 后不重投。Host/client 测试覆盖 live、stored 与 concurrent-create 路径中的 zone identity、逐操作提示词 provenance、commit gating、反序 watermark、语义 header identity、逐 event 前缀匹配、same-seq 升级、每个 window merge 出口和 reconnect generation。
|
||||
|
||||
Time-context 与 AgentLoop 生命周期测试覆盖已排队、已编辑、已丢弃、已取消和已重试的输入；混合 tab；带有晚到 steering 的延迟组装；pre-step 钩子、组装、检查点、追加与处置阶段的失败；同一步骤内选择最后一条权威；以及权威不会泄漏到下一轮次。显式 Loader 组合可以启动 source 与 built package。无密钥真实浏览器场景会通过完整工具 pipeline，针对既有的短 `after` case 和一个 absolute-time case 执行 `schedule_create`，观察 identity-matched 持久前缀，并从已附加 history 渲染 durable reminder card。刻意缺少的模型 adapter 会在 dispatch 后以错误关闭 turn，从而证明模型失败不会移除回执。
|
||||
|
||||
## 后果
|
||||
|
||||
- 提醒状态通过普通 Session persistence 跨进程重启并回放，无需新数据库或公开 service。
|
||||
- cold Session 不工作、不发送外部通知；重新打开后可能交付 overdue 提醒。
|
||||
- 每个 live 根只增加从 fold 派生的 timer、可选 idle wait 与一个 in-flight operation。
|
||||
- 同步 follow-up 获得准入后、持久 dispatch 前的狭窄崩溃窗口可能在恢复后重复提醒；本设计选择可见重复而非静默丢失，不作 exactly-once 承诺。
|
||||
- 严格的 after-only 协议有意保持小型；其他规则系列需要显式 record、时间与 recurrence 语义，而不是 dormant 字段。
|
||||
- cold Session 不工作、不发送外部通知；重新打开后可能交付 overdue 提醒，且每个工具／卡片都会显示 `session-local`。
|
||||
- 每个 live 根只增加从 fold 派生的 timer、可选 idle wait 与一个 in-flight operation。长等待和插件卸载不会创建第二套持久状态机。
|
||||
- Session 的默认时区不可变，且在较旧 history 中可能始终不可用。因此，旅行或并发 tab 可能需要显式时区，而不是悄然改变“明天 09:00”的含义。
|
||||
- 通用 commit-aware event-view 路径可供其他持久 event 复用，但为 client Session window 增加了事件身份检查与 generation-aware merge 行为。
|
||||
- 严格的一次性协议覆盖延迟目标和绝对时间目标。周期性规则系列仍需要显式 transition、catch-up 与 model-budget 语义，而不是休眠字段。

The current overlay supports one-shot reminders created with a positive whole-number `after_seconds` or an absolute `at` target. The model manages them through `schedule_create`, `schedule_list`, and `schedule_delete`; every result identifies the delivery mode as `session-local`.
|
||||
|
||||
An `at` target is either a strict RFC 3339 date-time with `Z` or a numeric offset, or a local `{ date, time, time_zone? }` value. The overlay loads time-context so the model sees the current date, local time, Session zone, and request-zone relationship before calling the tool. A local value may omit `time_zone` only when the current browser zone agrees with the immutable zone captured when that Session was created.
|
||||
|
||||
The browser samples its zone for each create or prompt operation. Resuming the Session from another zone does not overwrite the original default: an omitted local zone then returns `timezone_confirmation_required`, and the model asks which zone to use before retrying explicitly. Older headerless Sessions behave the same way with an unavailable default. Daylight-saving gaps are rejected and overlaps choose the first instant; successful records keep only the resulting UTC target.
|
||||
|
||||
The original Session log owns each reminder. A live root Agent waits and retries after it becomes idle, then queues a normal follow-up turn in that conversation. Closing the process or leaving the Session cold stops its in-memory timer without deleting the record; reopening that same Session restores the wait and delivers an overdue reminder. Merely reading cold history never activates it, and a fork does not inherit its parent's reminders.
|
||||
|
||||
Create and actual delete operations acknowledge success only after Session persistence confirms their event prefix. Schedule does not provide browser, operating-system, email, SMS, or other external notification. A durable dispatch records that the follow-up was queued; it does not acknowledge model success or user receipt.

当前 overlay 支持使用正整数 `after_seconds` 或绝对时间 `at` 目标创建的一次性提醒。模型通过 `schedule_create`、`schedule_list` 和 `schedule_delete` 管理它们；每个结果都会把交付模式标为 `session-local`。
|
||||
|
||||
`at` 目标可以是带 `Z` 或数值偏移量且严格符合 RFC 3339 的日期时间，也可以是本地 `{ date, time, time_zone? }` 值。此 overlay 会加载时间上下文，让模型在调用工具前看到当前日期、本地时间、Session 时区及其与请求时区的关系。只有当前浏览器时区与创建该 Session 时捕获且不可变的时区一致，本地值才可省略 `time_zone`。
|
||||
|
||||
浏览器会在每次创建或提示词操作时采样自身时区。从其他时区恢复 Session 不会覆盖原有的默认时区：此时若省略本地时区，就会返回 `timezone_confirmation_required`，模型会先询问应使用哪个时区，再显式指定该时区重试。没有标头的旧 Session 在默认时区不可用时也会采用相同行为。夏令时缺口会被拒绝，重叠时段则选择第一个时刻；成功创建的记录只保留所得的 UTC 目标。

每条提醒由原 Session 日志拥有。live 根 Agent 会等待并在恢复 idle 后重试，随后在该对话中排入一个普通 follow-up 轮次。关闭进程或让 Session 保持 cold 会停止内存 timer，但不会删除记录；重新打开同一个 Session 会恢复等待并交付逾期提醒。仅查看 cold 历史不会激活提醒，fork 也不会继承父 Session 的提醒。
|
||||
|
||||
创建和实际删除操作只有在 Session persistence 确认对应事件前缀后才会确认成功。Schedule 不提供浏览器、操作系统、邮件、短信或其他外部通知。持久 dispatch 会记录 follow-up 已经入队；它不确认模型成功或用户已收到提醒。

When `timeZone` is omitted, the plugin resolves the Node process's system zone once at plugin load. Node honors `TZ`; without that override, the host or container supplies the zone. An explicit `timeZone` must be an IANA identifier and is validated at plugin load.

When a Session has `SessionHeader.timeZone`, that immutable IANA zone formats its readings. A headerless Session instead uses the configured fallback; when `timeZone` is omitted, the plugin resolves the Node process's system zone once at plugin load. Node honors `TZ`; without that override, the host or container supplies the fallback. An explicit `timeZone` is validated at plugin load but does not override a Session-owned zone.

`refreshIntervalMs` must be a non-negative safe integer. Omission or `0` adds context to every eligible entering pre-step whose signal is not already aborted.

|

`refreshIntervalMs` must be a non-negative safe integer. Omission or `0` adds context to every eligible request preparation whose final pre-step decision contains input and whose signal is not already aborted. A positive value adds it only when the session has no earlier time-context injection, wall time moved backward, or at least that many milliseconds have elapsed since the latest injection.
|
||||
|
||||
## Timing semantics
|
||||
|
||||
The plugin prepends an `agent/pre-step` listener. When an injection is due and the downstream decision enters the proposed step, it adds one sourced `UserMessage` to the returned batch. AgentLoop records that context after `step/start` and before ordinary automatic compaction with source `{ kind: 'plugin', plugin: 'time-context' }`. A suppressed, rejected, or failed pre-step records nothing.
|
||||
The plugin opens a narrow authority envelope in `system-prompt/assemble` and closes it around `agent/pre-step`. It captures already-claimed input, and each user steering message admitted during asynchronous assembly is followed synchronously by a superseding same-step authority. AgentLoop includes the envelope's non-authority messages in the downstream pre-step proposal; after downstream edits, discards, or filtering settle, time-context derives the final authority from that decision.
|
||||
|
||||
An entering step records its downstream messages followed by exactly one final time-context `UserMessage` after `step/start`. Its source is `{ kind: 'plugin', plugin: 'time-context', authority }`, where `authority` identifies the proposed turn and step, the Session zone as `resolved` or `unavailable`, and the current request's client zones as `resolved`, `mixed`, or `missing`. An empty downstream decision consumes the envelope without opening a step or request.
|
||||
|
||||
If preparation exits before `step/start`, AgentLoop removes the envelope before closing the turn. It may settle an appendable final authority inside that failed turn, but an append failure drops the authority instead of leaving it pending. Cancellation cannot generate another authority after it wins; plugin disposal removes pending authorities and an in-flight listener contributes nothing after disposal. Steering and unrelated inbox work retain their ordinary cancellation policy, and no authority for an old turn or step can leak into a later request.
|
||||
|
||||
Positive-interval scheduling scans the raw durable session events for the latest `user/message` with that source, including a reading shadowed by compaction. The schedule therefore applies across turns and resumed processes without process-local cache state. It reduces append frequency and history growth but never removes an existing reading, and sessions schedule independently.
|
||||
|
||||
Step 1 measures from the latest preceding model-visible message, including the prompt that opened the turn. Later steps measure from the preceding time-context event in the same turn. Both baselines use durable session-event timestamps; backward wall-clock movement clamps elapsed time to zero. A missing first-step baseline, or a later step with no earlier same-turn reading because interval suppression skipped it, reports `unavailable`.
|
||||
Step 1 measures from the latest durable model-visible message before the current proposal; the prompt entering that same step has not been appended yet. Later steps measure from the preceding time-context event in the same turn. Both baselines use durable session-event timestamps; backward wall-clock movement clamps elapsed time to zero. A missing first-step baseline, or a later step with no earlier same-turn reading because interval suppression skipped it, reports `unavailable`.
|
||||
|
||||
A time reading records an entered pre-step batch, not a completed step or transmitted request. A later request-preparation failure can therefore leave the reading in history, but a downstream pre-step listener that rejects or fails prevents it from being recorded.
|
||||
A time reading records request preparation, not a completed step or transmitted request. A later request-preparation failure can therefore leave the reading in history, and a no-step failure can settle an already-sampled authority inside its failed turn.
|
||||
|
||||
The separately published `./invariant` companion checks each plugin-attributed reading against the open turn, next pre-step position, elapsed baseline, and durable event time. Its rendered timestamp must parse and cannot postdate the event; process suspension between sampling and append does not invalidate the reading.

The separately published `./invariant` companion strictly decodes each plugin-attributed authority and checks it against the open turn, next pre-step position, elapsed baseline, and durable event time. Its rendered timestamp must parse and cannot postdate the event; process suspension between sampling and append does not invalidate the reading.
|
||||
|
||||
The time reading stays in derived conversation history until a later compaction shadows it. Request headers contain no time-context state. Request reconstruction uses the complete durable surface prefix after each `step/start`, so transmitted requests need not map one-to-one to readings: request preparation can fail after step entry, while interval suppression can let a request reuse existing history without adding one.

The concrete `ReactLoopAgent`, its inbox, and run controls are package-internal. The package root exports only the plugin/service/config contract, and the package exports map exposes no `./src/*` escape hatch; lifecycle owners create agents through `ctx.agents` rather than naming, constructing, or starting driver internals. One prepared session can be claimed by only one concrete driver, and everything observable happens through session events and the `agent/*` event taxonomy.
|
||||
|
||||
The unified `send()` primitive routes content and source by (`target` × `wakeup`); `followup`/`steer`/`inject` are its fixed-preset aliases. `followup()` appends to the `next-turn` FIFO and wakes the driver, `steer()` appends to the `next-step` inbox and wakes it, and `inject()` appends to that same `next-step` inbox without waking it. At a turn boundary the driver opens the durable turn, then atomically claims pending next-step input plus one queued prompt; between steps it claims only next-step input. Claiming removes the batch through pure deletion splices and emits `agent/inbox/claimed { message, turn }` once per message. `agent/pre-step` then returns either rejection or the complete messages entering the proposed step. Rejection leaves the claimed batch removed and closes the turn without a step; input inserted after the claim remains pending, and idle injection waits until follow-up or steering wakes the driver.

Claiming removes the batch through pure deletion splices and emits `agent/inbox/claimed { message, turn }` once per message.
|
||||
|
||||
System-prompt assembly runs after that claim and before `agent/pre-step`. A provider may use this bounded asynchronous window to stage an authority-delimited envelope in the next-step inbox. The driver adds the envelope's ordinary messages to the pre-step proposal, so guards and transformations see late steering, but keeps preparation authorities outside that decision. Rejection leaves the claimed batch removed; an empty enter decision consumes the envelope without opening a step. A non-empty enter appends the transformed messages followed by only the envelope's final authority after `step/start`. If preparation fails before then, the driver removes the envelope and settles at most its final appendable authority inside the no-step turn, so no old authority leaks while unrelated pending input retains its normal ownership. The [durable time-context decision](../../../.agents/notes/implemented/feature/2026-07-16-durable-per-step-time-context.md) owns the current producer.
|
||||
|
||||
Input inserted after an ordinary claim remains pending unless it belongs to that bounded envelope, and idle injection waits until follow-up or steering wakes the driver.
|
||||
|
||||
Every inbox mutation publishes one normalized `agent/inbox/spliced` event before changing the live projection. Insertions, edits, removals, claiming, and cancellation replay through the same standard splice coordinates. Ordinary removals carry `outcome: 'canceled'` and emit `agent/inbox/discarded { message }`; claiming uses pure deletions with no outcome, after which the loop emits `agent/inbox/claimed`. Every insertion emits `agent/inbox/inserted { message }`. `MessageId` stays unique across both pending lists, and synchronous durable-event observers can reconstruct removed values from the pre-splice projection.

`dsh-tool-schedule` gives future live root agents three session-scoped tools for durable one-shot reminders. Version 1 accepts positive safe-integer `after_seconds` delays and absolute `at` targets. The session event log owns reminder state; timers, tool values, and model followups are disposable projections of that log.
|
||||
|
||||
## Composition
|
||||
|
||||
Load this function plugin after `ctx.sessions`, `ctx.agents`, `ctx.tools`, `ctx.sessionPersistence`, and the persistence listener that implements Session flushes. Static injection makes a missing persistence service a composition error. The plugin listens only to later `agent/created` events, installs on runtime roots, and registers all tools through the exact `agent.ctx`. Agents that already existed when the plugin loaded and runtime children do not receive Schedule.
|
||||
|
||||
Load `@deepseek-ai/dsh-time-context` before publishing a root that should resolve local `at` values without an explicit zone. The official Schedule Web overlay does so. Explicit-offset and explicit-zone values remain usable without an implicit-zone authority.
|
||||
|
||||
Every operation that reads or decides from the Schedule fold first awaits `ctx.sessions.flush(session)`. A missing, rejected, or detached persistence path returns `persistence_uncertain`; it never turns an unconfirmed live suffix into a list or not-found answer. A successful create or actual delete also awaits a post-append barrier before confirming the mutation.
|
||||
|
||||
## Durable state
|
||||
|
||||
The package owns the strict version-1 `schedule/change` create, delete, and dispatch union. Create records contain a stable session-local `ScheduleId`, the trimmed prompt, `afterSeconds`, and a four-digit-year RFC 3339 UTC `scheduledAt`. Delete and one-shot dispatch carry only the id.
|
||||
The package owns the strict version-1 `schedule/change` create, delete, and dispatch union. Every create record contains a stable session-local `ScheduleId`, the trimmed prompt, and a four-digit-year RFC 3339 UTC `scheduledAt`. An `after` record also stores `afterSeconds`; an `at` record stores no copy of the submitted offset, local calendar fields, or interpreting zone. Delete and one-shot dispatch carry only the id.
|
||||
|
||||
Replay rejects unknown versions, extra fields, reused ids, and delete or dispatch transitions against inactive records. Normal sessions fold the complete log. A fork folds only `session.events.slice(session.header.seedLength ?? 0)`, so it does not inherit its parent's reminders. The package's `./invariant` companion applies the same policy to existing logs and candidate events.
|
||||
|
||||
`scheduleReminderPresentation(events, dispatchSeq, seedLength)` is the pure Host-facing receipt projection. It returns `scheduleId`, prompt, and occurrence from the dispatch's nearest preceding same-id create; the client renderer adds the fixed `session-local` label. The current fork's `seedLength` is a hard boundary for child-owned dispatches, while inherited dispatches search their persisted prefix; resumed ancestors therefore remain renderable, nested generations may reuse session-local ids, and presentation never changes live ownership.
|
||||
|
||||
## Absolute-time authority
|
||||
|
||||
The `at` selector is either a strict `YYYY-MM-DDTHH:mm:ss[.S|.SS|.SSS](Z|±HH:MM)` string or `{ date: "YYYY-MM-DD", time: "HH:mm:ss[.S|.SS|.SSS]", time_zone?: string }`. The offset form already identifies one instant. The local form validates an explicit `UTC` or IANA Area/Location zone, or may omit `time_zone` only when the current step's final time-context authority reports one resolved client zone equal to the immutable Session zone.
|
||||
|
||||
The Web Host validates and canonicalizes the browser zone at Session creation and on every prompt. Session creation fixes `SessionHeader.timeZone`; each prompt instead carries its own `clientTimeZone` in the user-message source, so concurrent tabs do not overwrite shared state. A headerless Session, a missing or mixed client authority, or a client/Session mismatch returns `timezone_confirmation_required` with the known zones and requires an explicit `time_zone`.
|
||||
|
||||
Local times inside a daylight-saving gap are rejected. An overlap chooses its first, earlier instant. A successful create retains only the canonical UTC target, and no Schedule path reads the process time zone.
|
||||
|
||||
## Management tools
|
||||
|
||||
The generated [tool catalog](../../../docs/tool-catalog.md) owns the argument and output schemas for `schedule_create`, `schedule_list`, and `schedule_delete`. Their canonical values use camelCase record fields even though model input uses `after_seconds`.
|
||||
|
||||
One Agent-scoped queue serializes each accepted management transaction and the live owner's due transaction from preflight through any post-append barrier. Direct callers therefore cannot interleave a fold with another Schedule mutation or observe a dispatch before its own barrier. `schedule_create` validates shape-only failures before entering that queue, then checkpoints, allocates a never-reused id, appends the create, and checkpoints again. `schedule_list` returns every active record in create order with `state: "scheduled" | "overdue"` and `deliveryMode: "session-local"`. `schedule_delete` rejects an empty or whitespace-padded id before entering the queue and appends only for an active id; an unknown or terminal id returns `{ id, deleted: false, code: "schedule_not_found" }` after its preflight.
|
||||
One Agent-scoped queue serializes each accepted management transaction and the live owner's due transaction from preflight through any post-append barrier. Direct callers therefore cannot interleave a fold with another Schedule mutation or observe a dispatch before its own barrier. `schedule_create` requires exactly one of `after_seconds` or `at`, validates shape-only failures before entering that queue, then checkpoints, allocates a never-reused id, appends the create, and checkpoints again; an absolute target must be strictly future. `schedule_list` returns every active record in create order with `state: "scheduled" | "overdue"` and `deliveryMode: "session-local"`. `schedule_delete` rejects an empty or whitespace-padded id before entering the queue and appends only for an active id; an unknown or terminal id returns `{ id, deleted: false, code: "schedule_not_found" }` after its preflight.
|
||||
|
||||
Every successful management preflight also asks the live owner to recompute. This matters after a create or delete barrier returned `persistence_uncertain`: a later list or mutation can confirm the retained batch and immediately arm or retire the now-durable record without a private persistence-retry timer.
|
||||
|
||||
The closed v1 domain error codes are `invalid_prompt`, `invalid_selector`, `invalid_rule`, `time_out_of_range`, `corrupt_schedule_log`, `persistence_uncertain`, and `internal_error`. Diagnostics are stable and do not expose backend exceptions. Rendered content is deterministic JSON of the canonical value; generic tool-result policy remains responsible for any model-facing spill behavior.

The closed v1 domain error codes are `invalid_prompt`, `invalid_selector`, `invalid_rule`, `invalid_time_zone`, `timezone_confirmation_required`, `not_future`, `time_out_of_range`, `corrupt_schedule_log`, `persistence_uncertain`, and `internal_error`. Diagnostics are stable and do not expose backend exceptions. Rendered content is deterministic JSON of the canonical value; generic tool-result policy remains responsible for any model-facing spill behavior.

|
||||
|
||||
An overdue reminder first checkpoints persistence. If a turn or another maintenance task already owns the Agent, `runMaintenance()` rejects the idle-phase claim; the record stays active and the owner retries after `whenIdle()`. A successful maintenance task samples one decision time, builds the complete framing, synchronously queues `followup()`, and appends an id-only dispatch before releasing the phase. Waking input remains parked until that release, after which the owner checkpoints dispatch. Framing or synchronous followup failure writes no dispatch. An append failure faults that owner because the message may already be queued; a barrier rejection leaves the dispatch pending for a later ordinary preflight and does not start a private retry timer.
|
||||
|
||||
The follow-up opens a normal later turn after the Agent becomes fully idle; it never steers or interrupts the current turn. Its assistant output appears through the ordinary conversation transcript. Dispatch means that the follow-up was queued and recorded, not that the model succeeded or the user read the answer, and Schedule adds no independent Web receipt.
|
||||
|
||||
Agent or plugin disposal cancels timers, stops new work, and awaits in-flight preflights and idle waits. It never appends delete records during teardown.

## 组合
|
||||
|
||||
请在 `ctx.sessions`、`ctx.agents`、`ctx.tools`、`ctx.sessionPersistence`，以及实现 Session flush 的持久化监听器之后加载此函数插件。静态注入会使缺少持久化服务的组合直接失败。此插件只监听后续的 `agent/created` 事件，在运行时根 agent 上安装，并通过完全相同的 `agent.ctx` 注册所有工具。插件加载时已经存在的 agent 与运行时子 agent 不会获得 Schedule。
|
||||
|
||||
若根 agent 需要在未显式指定时区时解析本地 `at` 值，请在发布该 agent 前加载 `@deepseek-ai/dsh-time-context`。官方 Schedule Web overlay 会按此顺序加载。带显式偏移量的值和带显式时区的值即使没有隐式时区 authority 仍可使用。
|
||||
|
||||
每项从 Schedule 折叠结果读取或作出判断的操作，都会先等待 `ctx.sessions.flush(session)`。持久化路径缺失、拒绝或已分离时，操作返回 `persistence_uncertain`；它绝不会把未经确认的 live 后缀当成列表或未找到结果。成功创建或实际删除后，还会等待追加后的持久化 barrier（屏障）再确认变更。

|
||||
|
||||
回放会拒绝未知版本、额外字段、重复使用的 id，以及针对非活动记录的 delete 或 dispatch 转换。普通会话折叠完整日志。fork 只折叠 `session.events.slice(session.header.seedLength ?? 0)`，因此不会继承父会话的提醒。此包的 `./invariant` 配套项会对现有日志和候选事件应用相同策略。
|
||||
|
||||
`scheduleReminderPresentation(events, dispatchSeq, seedLength)` 是供 Host 使用的纯回执投影。它从 dispatch 之前最近的同 id create 返回 `scheduleId`、prompt 和 occurrence；client renderer 添加固定的 `session-local` 标签。当前 fork 的 `seedLength` 是 child 自有 dispatch 的硬边界，而继承的 dispatch 则会搜索其已持久前缀；因此恢复后的祖先仍可渲染，嵌套 generation 可以复用会话本地 id，presentation 绝不会改变 live ownership。
|
||||
|
||||
## 绝对时间 authority
|
||||
|
||||
`at` selector 可以是严格的 `YYYY-MM-DDTHH:mm:ss[.S|.SS|.SSS](Z|±HH:MM)` 字符串，也可以是 `{ date: "YYYY-MM-DD", time: "HH:mm:ss[.S|.SS|.SSS]", time_zone?: string }`。偏移量形式本身即可确定一个时刻。本地形式会校验显式指定的 `UTC` 或 IANA Area/Location 时区；仅当当前步骤最终的 time-context authority 给出唯一一个已解析的客户端时区，且该时区与不可变的 Session 时区相同时，才可以省略 `time_zone`。
|
||||
|
||||
Web Host 会在创建 Session 时以及每次提交提示词时校验并规范化浏览器时区。Session 创建会固定 `SessionHeader.timeZone`；每条提示词则会在用户消息来源中携带自己的 `clientTimeZone`，因此并发标签页不会覆盖共享状态。如果 Session 没有 header、客户端 authority 缺失或混杂，或客户端与 Session 不匹配，系统会返回 `timezone_confirmation_required` 并附上已知时区，同时要求显式指定 `time_zone`。
|
||||
|
||||
落在夏令时空档内的本地时间会被拒绝。遇到重叠时会选择第一次出现的较早时刻。创建成功后只保留规范化后的 UTC 目标，Schedule 的任何路径都不会读取进程时区。
|
||||
|
||||
## 管理工具
|
||||
|
||||
生成的[工具目录](../../../docs/tool-catalog.md)负责 `schedule_create`、`schedule_list` 和 `schedule_delete` 的参数与输出 schema。虽然模型输入使用 `after_seconds`，但其规范值中的记录字段使用 camelCase。
|
||||
|
||||
一条 Agent-scoped 队列会将每项已接纳的管理事务与 live owner 的到期事务从 preflight 到任何 post-append barrier 全程串行化。因此，直接调用方无法让一次 fold 与另一项 Schedule 变更交错，也无法在自身的 barrier 前观察到 dispatch。`schedule_create` 会在进入该队列前验证只依赖输入形状的失败，随后执行检查点、分配永不复用的 id、追加 create，再次执行检查点。`schedule_list` 按创建顺序返回所有活动记录，其中包含 `state: "scheduled" | "overdue"` 与 `deliveryMode: "session-local"`。`schedule_delete` 会在进入该队列前拒绝空 id 或前后带空白的 id，并只为活动 id 追加事件；未知或已终结的 id 会在 preflight（预检）后返回 `{ id, deleted: false, code: "schedule_not_found" }`。
