 ## Decision
 
-**One primitive, three preset aliases.** `Agent` is now an abstract class whose single abstract `send(content, { target, wakeup, source, contexts, meta })` covers the (`target` × `wakeup`) matrix. `followup` (`next-turn`/wakeup), `steer` (`next-step`/wakeup), and `inject` (`next-step`/no-wakeup) are concrete delegates on the base class, so concrete drivers implement `send` once and inherit the ergonomic presets. `wakeup` means "make the model run": wake a parked driver for a `next-turn` item, or force a continuation for a running `next-step` item. `send` defaults to `{ target: 'next-turn', wakeup: true }`, so every prior bare `agent.send(content)` call keeps its exact behavior. `next-turn`/no-wakeup (queue without waking) is now representable with no alias and no current caller.
+**One acceptance mechanism, four intent helpers.** The concrete loop resolves `followup`, `queue`, `steer`, and `inject` into one (`target` × `wakeup`) acceptance mechanism. `followup` is `next-turn`/wakeup, `queue` is `next-turn`/no-wakeup, `steer` is `next-step`/wakeup, and `inject` is `next-step`/no-wakeup. The public structural interface exposes that mechanism as `send(ResolvedAgentInput)` for callers that already have fully resolved routing; every field is mandatory, and the discriminated input type excludes attached contexts from injection. The [intent-named delivery decision](2026-07-24-intent-named-agent-delivery.md) owns that superseding interface choice. Internally, `wakeup` means “make the model run”: wake a parked driver for an ordinary item or force a continuation for running steering.
 
-**inject keeps its mechanism.** The `next-step`/no-wakeup path is exactly the old `inject`: durable model-facing context appended at the current log position (deferred behind an executing tool batch), or a one-shot `injection` turn when idle. It bypasses the FIFOs entirely and defaults its source to `{ kind: 'plugin', plugin: '' }`, never `{ kind: 'user' }`.
+**inject keeps its mechanism.** `inject` appends durable model-facing context at the current log position (deferred behind an executing tool batch), or opens a one-shot `injection` turn when idle. It bypasses the FIFOs entirely, accepts no attached contexts, and defaults its source to `{ kind: 'plugin', plugin: '' }`, never `{ kind: 'user' }`.
 
 **context/message is gone.** Injected context is now a `user/message` whose `source` is a non-`user` kind (plugin or goal). `PromptMessageData` gained the optional `meta` that `context/message` carried. The surface, derivation, and `SurfaceEventType` drop `context/message`; consumers that need "is this a human prompt?" read `source.kind === 'user'` instead of the event type. This keeps goal-authority's human-authority check exactly as strict as before — an injected message defaults to a plugin source and can never satisfy `source.kind === 'user'`.
 
 **Goal replay disambiguates by round, not type.** A goal state change is a round-zero goal-sourced `user/message` carrying `goal/change` metadata; a positive round is an admitted continuation prompt. `decodeGoalEvent` now takes a `user/message` and still fails loud on goal metadata under a non-goal source or a goal source lacking metadata.
 
-**`send` returns an id.** `send` (and the aliases) return an opaque branded `AgentMessageId` for the accepted message; `send`'s previous return was `void`.
+**Delivery returns an id.** Each delivery method returns an opaque branded `AgentMessageId` for the accepted input. FIFO methods carry it through their inbox lifecycle events; injection bypasses those events.
 
-**Three inbox events replace agent/queued.** `agent/inbox/enqueue` (an item entered a FIFO), `agent/inbox/dequeue` (the driver claimed one), and `agent/inbox/discard` (`cancel()` dropped pending items) each carry an `AgentMessage` — the accepted message including its returned `id`, `target`/`wakeup`, source, and contexts — so a caller can correlate a queued item with its lifecycle. Injection never touches a FIFO and emits none of these. Every FIFO entry publishes an enqueue, including the loop-authored continuation-reason steer (`agent/turn-continuation` returning `{ action: 'continue', reason }`), so the ledger stays balanced with its later dequeue or discard. The `dsh-agent` invariant companion asserts FIFO conservation: a per-agent outstanding count that dequeue and discard can never drive negative.

 ## Consequences
 
-The delivery surface is now one primitive plus three self-documenting presets, and the (`target` × `wakeup`) matrix makes previously-unreachable combinations explicit. One durable message type serves prompts, injected context, and goal rounds, so the surface projection and every "human prompt?" check simplify to a `source` test. The cost: `Agent` became an abstract class, so object-literal test fakes must supply `followup` and cannot spread a class-typed value without re-casting (prototype methods are non-enumerable); the goal fold's channel split moved from event type to `source.round`; and every consumer that filtered `context/message` now filters `user/message` by source. The turn-enclosure and reconstruction invariants are unchanged — an idle injection still wraps a one-shot turn, now emitting `user/message` instead of `context/message`.
+The concrete driver has one delivery mechanism. Four common helpers hide its (`target` × `wakeup`) matrix behind caller intent, while `send` exposes the fully resolved matrix for advanced callers.

-`wakeup` is the "should the model run" signal, so the inbox distinguishes `hasWakingQueued` (drives the loop and idle/quiescence decisions) from `hasQueued` (anything to dequeue): a lone `next-turn`/no-wakeup item stays parked at idle and rides along the next waking send, and `whenIdle`/`cancel` settle quiescence off the waking signal (a lone quiet item takes `whenIdle`'s fast path, so no waiter is ever left hanging). `SendOptions.meta` on a queued or steering send is carried onto the durable `user/message`/`steering/message`, matching injection; it is intentionally not on the live `AgentMessage` event, which carries only routing facts. Every enqueued id gets exactly one terminal lifecycle event: a terminal stop that drops pending steering emits `agent/inbox/discard` (both at the in-turn stop point and on the post-turn drain of late steering), and disposal discards any still-pending items before the loop exits. The `agent/inbox/*` payload is frozen so a listener cannot mutate the shared correlation object mid-dispatch, and a loop-authored continuation reason is snapshotted and frozen like a public send. Injection (`next-step`/no-wakeup) validates its payload up front — before opening the idle one-shot turn, honoring the "invalid input throws before any append" contract — and rejects attached `contexts` (which belong only to inbox messages) rather than silently dropping them. `gen-cordis-api` collects exported classes (public members, body-stripped) so the now-class `Agent` and its transitive shapes still appear in the model-facing API catalog.

+
+## Problem
+
+A configurable `send(content, { target?, wakeup?, ... })` makes every caller learn the loop's routing matrix, its defaults, and the interaction between active-turn targeting and model activation. Optional routing fields also let advanced-looking calls silently become ordinary sends. Most callers have one semantic intent, while some adapters already possess exact routing facts and should not have to reverse-map them into a helper name.
+
+Sharing helper implementations through an abstract `Agent` class also makes the public seam nominal in practice. Object-literal adapters and tests must inherit prototype methods even though the package promises a swappable structural handle. The shared base exists only to forward fixed arguments, while the concrete loop remains the sole production adapter.
+
+## Decision
+
+`Agent` is a structural interface with four intent-named delivery helpers:
+
+- `followup()` queues an ordinary turn and wakes the driver.
+- `queue()` queues an ordinary turn without waking an idle driver.
+- `steer()` targets the running turn and requests another step; while idle it becomes a waking ordinary turn.
+- `inject()` appends model-facing context without running the model.
+
+`followup`, `queue`, and `steer` accept `SendOptions`; `inject` accepts `InjectOptions`, which omits attached contexts because injection has no inbox item to own them. `followup` names the waking next-turn operation used for both initial prompts and later independent prompts.
+
+`Agent` also exposes `send(ResolvedAgentInput)` for callers that already hold the complete route. Every field is mandatory: content, source, contexts, metadata (possibly `undefined`), target, and wakeup. The discriminated union requires the empty context tuple for non-waking next-step injection. `ReactLoopAgent` implements this method once, and all four helpers resolve their defaults before delegating to it. The method accepts the delivery facts as one resolved input; acceptance can still lead to later dequeue, discard, or durable injection rather than eventual delivery.
+
+The target/wakeup matrix is an explicit advanced part of the structural `Agent` interface, not the ordinary helper options and not a base-class implementation seam. With one concrete adapter, a protected subclass seam would be hypothetical; callers and tests use the same public interface.
+
+## Alternatives considered
+
+**Keep the resolved primitive private.** This minimizes the public method count, but forces adapters that already hold exact target/wakeup facts to reverse-map them into helper calls and removes the reusable type for that resolved state.
+
+**Use configurable `send(content, options)` as the primitive.** Optional routing fields would let advanced-looking calls silently become ordinary sends. One mandatory discriminated input keeps the resolved route explicit and rejects attached contexts on injection.
+
+**Name the primitive `acceptInput`, `sendInternal`, or `addMessageAdvanced`.** `acceptInput` describes the synchronous acceptance boundary but not the caller's delivery action. A public method must not describe itself as internal, and `addMessageAdvanced` is inaccurate because the input may later be discarded.
+
+**Use `send(content, options)` as the waking-turn helper.** This reserves the shortest delivery name for one preset and forces callers with complete target/wakeup facts through a less direct primitive name. `followup` distinguishes the next-turn/wakeup intent while leaving `send` for the resolved operation.
+
+**Bind source first through a public sender object.** A source-bound adapter can make attribution explicit for repeated producers, but it adds another public object and does not simplify one-off human input. The existing source default remains, with the standing requirement that non-human producers label their content.
+
+## Verification
+
+Focused agent-loop coverage exercises direct fully resolved acceptance, waking sends, quiet queues, active and idle steering, injection, source/context snapshots, cancellation, and inbox lifecycle correlation through the public methods. Type-level coverage uses structural `Agent` fakes, requires every `ResolvedAgentInput` field, requires empty contexts on its injection variant, and keeps routing fields out of `SendOptions`. The keyless Cordis inspection snapshot pins the structural interface without an abstract-class implementation.
+
+## Consequences
+
+Ordinary callers choose one verb instead of encoding two routing axes; advanced callers may submit the exact discriminated route. The concrete loop retains one acceptance path and one ownership boundary, while the structural interface preserves simple adapters and fakes. Adding a common delivery intent still requires an explicit public helper and mapping rather than another optional matrix combination.
+
+The advanced method adds interface surface and requires structural fakes to implement it. In return, resolved routing has one typed representation, while helper defaults and mappings stay beside the only implementation that owns them.

+# Agent Note: 按意图命名公开的 agent 投递

+## 问题
+
+可配置的 `send(content, { target?, wakeup?, ... })` 会迫使每个调用方理解循环的路由矩阵、默认值，以及活跃轮次目标与模型激活之间的相互作用。可选路由字段还会让看似高级的调用悄然变成普通投递。大多数调用方只有一种语义意图，而有些适配器已经持有确切的路由信息，不应再被迫将这些信息反向映射为某个辅助方法名称。
+
+通过抽象 `Agent` 类共享辅助方法的实现，实际上也会让公开 seam 具有名义类型约束。对象字面量适配器和测试必须继承原型方法，尽管该包承诺提供一个可替换的结构化句柄。共享基类只负责转发固定参数，而具体循环仍是唯一的生产适配器。
+
+## 决策
+
+`Agent` 是一个结构化接口，提供四种按意图命名的投递辅助方法：
+
+- `followup()` 将一个普通轮次入队并唤醒驱动器。
+- `queue()` 将一个普通轮次入队，但不唤醒空闲驱动器。
+- `steer()` 以运行中的轮次为目标并请求另一个步骤；空闲时，它会变成一个唤醒式普通轮次。
+- `inject()` 追加面向模型的上下文，但不运行模型。
+
+`followup`、`queue` 和 `steer` 接收 `SendOptions`；`inject` 接收 `InjectOptions`，后者不包含附加上下文，因为注入没有 inbox 项来拥有它们。`followup` 为唤醒式下一轮操作命名，这项操作既用于初始提示词，也用于后续的独立提示词。
+
+`Agent` 还公开 `send(ResolvedAgentInput)`，供已经持有完整路由的调用方使用。每个字段都必须提供：内容、来源、上下文、元数据（可以是 `undefined`）、目标和唤醒标志。对于目标为下一步且不触发唤醒的注入，可辨识联合类型要求上下文为空元组。`ReactLoopAgent` 统一实现这个方法；四个辅助方法都会先解析各自的默认值，再委托给它。调用方以一个解析后的输入向该方法提交各项投递事实；接受之后，工作仍可能在稍后出队、被丢弃或持久注入，而不是最终必然送达。
+
+结构化 `Agent` 接口显式包含面向高级用法的 target/wakeup 矩阵；该矩阵不属于普通辅助方法的选项，也不是基类实现 seam。只有一个具体适配器时，protected 子类 seam 只是假想的；调用方和测试使用同一个公开接口。
+
+## 考虑过的替代方案
+
+**让解析后的原语保持私有。** 这会把公开方法数量降到最低，但会迫使已经持有精确 target/wakeup 路由信息的适配器将其反向映射为辅助方法调用，也会移除表示该解析后状态的可复用类型。
+
+**使用可配置的 `send(content, options)` 作为原语。** 可选路由字段会让看似高级的调用悄然变成普通投递。一个各字段均为必填项的可辨识输入既能让解析后的路由保持显式，也会拒绝为注入附加上下文。
+
+**把原语命名为 `acceptInput`、`sendInternal` 或 `addMessageAdvanced`。** `acceptInput` 描述了同步接受边界，却没有描述调用方的投递操作。公开方法不应在名称中把自己称为内部方法，`addMessageAdvanced` 也不准确，因为输入可能在之后被丢弃。
+
+**使用 `send(content, options)` 作为唤醒轮次的辅助方法。** 这会让最简短的投递名称只表示一种预设操作，并迫使持有完整 target/wakeup 信息的调用方改用一个不够直接的原语名称。`followup` 明确区分下一轮/唤醒意图，并把 `send` 留给解析后的操作。
+
+**先通过公开的发送方对象绑定来源。** 对于重复产生消息的来源，来源绑定适配器可以明确标注归属，但它会增加一个公开对象，也不会简化一次性的人类输入。现有的来源默认值予以保留，同时继续要求非人类生产方标注其内容。
+
+## 验证
+
+聚焦的 agent-loop 覆盖率测试通过公开方法覆盖直接接受完全解析的输入、唤醒式投递、静默排队、活跃与空闲状态下的 steering（中途引导）、注入、来源与上下文快照、取消，以及 inbox 生命周期关联。类型级覆盖使用结构化 `Agent` 测试替身，要求提供 `ResolvedAgentInput` 的每个字段，要求其注入变体的上下文为空，并确保 `SendOptions` 不包含路由字段。无密钥的 Cordis 检查快照固定了不采用抽象类实现的结构化接口。
+
+## 后果
+
+普通调用方选择一个动词即可，无需编码两条路由轴；高级调用方则可提交经过判别的精确路由。具体循环保留一条接受路径和一个归属边界，而结构化接口保留了对简单适配器和测试替身的支持。新增一种常见投递意图时，仍需要显式提供公开辅助方法及其映射，而不是再增加一种可选的矩阵组合。
+
+这个高级方法会扩大接口范围，并要求结构化测试替身实现它。作为回报，解析后的路由只有一种类型化表示，而辅助方法的默认值和映射仍留在拥有它们的唯一实现旁边。
