Every backend marks its replacement `user/message` with `COMPACT_CHECKPOINT_SOURCE`; client and wire consumers import that value and `isCompactCheckpointSource()` from the cordis-free `@deepseek-ai/dsh-compact/checkpoint` subpath, while the package root re-exports both for host consumers. The predicate keeps checkpoint recognition independent of any one backend. Implementations must forward the supplied signal to summarization.

`changed` and `summary` leave the conversation surface unchanged but still close and persist the failed attempt in the log. `commit` may follow partial mutation; `persistence` means the in-memory bracket closed but its flush failed. Cancellation remains separate and throws the exact abort reason after required cleanup.
Pressure compaction runs at serial `agent/step` before request derivation. Once pressure or canonical overflow qualifies, compact-basic invokes optional [`ctx.toolResultPrune`](../../packages/compact/compact-tool-result-prune/README.md) before range selection, remeasures through `ctx.tokenMeter`, and can advance the surface without a summary. Failed-request recovery runs through `agent/request-error` after the failed step closes and returns a retry action only when the surface replacement generation advances, even if later summary work throws after pruning; cancellation still wins. Region boundaries preserve tool-call/result pairing but not whole turns, allowing early closed steps of one oversized turn to compact. `dsh-compact-basic` owns thresholds, retained-tail policy, overflow caps, and failure handling.

The fixed-preset aliases own `target` and `wakeup`; their already identified `UserMessage` carries role, content, and provenance. Its `MessageId` remains stable when an edit replaces content or strict steer transfers the immutable message. The original queued occurrence ends and strict steer accepts a new steering occurrence with a distinct `InboxItemId`. Injection bypasses the FIFOs and never appears on inbox lifecycle events.
Every pending occurrence is its `UserMessage`; `MessageId` is the sole identity. `Inbox.append`, `prepend`, `replace`, `remove`, `clear`, `splice`, and `claim` record normalized durable `agent/inbox/spliced` mutations and reject duplicate pending ids. `replace(messageId, newMessage)` and `remove(messageId)` locate the pending message across both lists; replacement may change identity and emits the old message as discarded followed by the new message as inserted. Ordinary removals and `clear()` are cancellations. `claim(target)` removes the proposed step batch — all `next-step` input plus, at a turn boundary, one `next-turn` message — through pure deletion splices without emitting discarded notifications, and the loop separately emits per-message claimed notifications. Whole-queue consumers such as UI projections reconstruct `nextTurn` and `nextStep` from the durable splices, while consumers following one message use the exact `agent/inbox/inserted`, `claimed`, and `discarded` notifications.

`AgentStatus` is `'idle' | 'running'`, and `SessionId` is branded. Disposal removes the agent from the registry and emits `agent/disposed`; it is not a terminal status value. `running` describes the driver-wide drain interval and may span consecutive queued turns; it does not prove a turn is still open. `acceptsNextStep` is the narrower routing predicate for callers that must choose between steering the current admission/turn and submitting a fresh admitted prompt. A live turn-admission reservation is quiescence-relevant without changing `status` or turning later queue entries into steering; its only authority is to defer the next driver claim until release. `AgentOptions` is merge-extensible: core declares `provider?`, `model?`, and `maxTokens?` (dispatch requires provider and model after `agent/request`). When present, `maxTokens` must be a positive safe integer and caps every conversation-model request; omission allows the exact-model adapter default to materialize before the request header, or otherwise leaves provider behavior unchanged. Persona belongs to `dsh-system-prompt`: an agent-scoped `deployment:persona` may shadow the global default.

The cause is a TypeScript-enforced same-process input. An active `TurnCancellation` holder copies its discriminant into the runtime-only `AbortSignal.reason` and is retired before `turn/end` publication; the frozen `AbortSignal.reason` remains readable after that retirement. Only the loop reads the cause (`user`, `parent`, or lifecycle-only `disposed`) back off its own machine-private signal at settlement — there is no public reader, and a signal grants cooperating listeners no classification authority. Durable `turn/end` retains the coarse `{ kind: 'aborted' }` outcome; request provenance would require a separate durable event rather than overloading the terminal result.

Pre-step decisions use the same identified `UserMessage` shape as durable user-role input. The entered batch is authoritative and preserves every message's identity and provenance. Hook bridges map their native decision fields onto this typed result.

`agent/prompt-submit` returns a `PromptDecision` before a turn opens. Allow may rewrite the claimed prompt or attach `additionalContexts`; block rejects admission without creating turn events:
`agent/pre-step` receives one payload carrying the exclusive claimed batch (`messages`), the proposed step's coordinates (`turn`, `step`), and the current turn's cancellation `signal`. The initial proposal runs inside an open turn before any step; a tool continuation may submit an empty claimed batch between steps:
It returns a `PreStepDecision`. Reject opens no step. Enter supplies the complete message batch appended after `step/start`; claimed messages omitted by the final decision remain removed, while input inserted after the claim stays pending:
```ts type-equiv
/**
* Prompt interception result. `allow.content` replaces the prompt, while

`agent/request-error` runs after a failed model step closes and before its turn closes. Listeners can repair durable state or await policy work while the failed turn's signal is still live. A handling listener returns `{ kind: 'retry' }` without calling `next()`; the default `undefined` leaves the failure terminal.

- **Provider stalls are bounded at the transport.** Both shipping remote adapters expose positive finite `streamIdleTimeoutMs` with a five-minute default. The watchdog arms only while iterator `next()` is outstanding, uses one stable signal for the whole request, maps its own expiry to `TIMEOUT`, and keeps an earlier caller abort as `ABORTED`.
- **Context overflow has one canonical code.** Both DeepSeek adapters classify explicit provider detail through `isContextWindowExceededError()` and surface `CONTEXT_WINDOW_EXCEEDED`, whether the failure arrives as a thrown HTTP `LlmError` or an in-band finish error. Consumers route on the code, never provider text.
- **An empty completion is a retryable error, not a silent success.** Both adapters map a terminal `stop` finish that carried no content blocks to `finish {kind:'error'}` with the canonical `EMPTY_RESPONSE` code, and `dsh-llm-retry` retries it by default; see [empty model responses are retryable](../../.agents/notes/implemented/bug-fix/2026-07-24-empty-model-response-is-retryable.md).
- **Every provider HTTP request carries the app-attribution header.** Adapters send `attributionHeaders()` (below) - the `User-Agent` baseline - and prove it with a wire-level test (mock server asserting the received header, or the library's header hook for a library-backed adapter).
- **Every provider HTTP request carries the app-attribution header.** Adapters send `attributionHeaders()` (below), the `User-Agent` baseline.
- **Replay state is adapter-owned.** A successful `finish` may carry lossless-JSON state needed to reconstruct a native provider response. The loop stores it with the assembled assistant message. On a later request, `LlmService` passes the state only when the historical provider and target provider are currently registered to the exact same adapter instance. That adapter validates the state and owns any cross-model or cross-provider conversion; other adapters receive the provider-neutral content and provenance without the private state.
This contract is pinned down by two deliberately independent implementations: `dsh-llm-deepseek` (direct fetch, SSE framing via `eventsource-parser`) and `dsh-llm-pi-ai` (a generic multi-provider adapter through `@earendil-works/pi-ai`). The library-backed adapter exercises the finish-chunk error path, while transport-boundary tests prove each idle watchdog stops its actual request.

A backend that reloads a log crashed mid-turn finds an open `turn/start` with no `turn/end`. It does **not** truncate — a single turn can be huge in a long-horizon task (many steps, large tool output), and those events were durably appended before the crash. Instead it closes the orphaned turn with a synthetic `turn/end { reason: { kind: 'interrupted' } }`, keeping the interrupted execution balanced without changing any standalone events before or after it. `interrupted` is the one `TurnEndReason` no loop emits (see [session.md](session.md#why-a-turn-ended-turnendreasonmap)).
Repair applies only to cold sessions. For a live id, `SessionPersistence.load(id)` snapshots the in-memory log, waits until that snapshot is durable, and returns it with the stored header only when balanced; an open live turn rejects rather than receiving synthetic interruption boundaries. A coordinator-backed cold load reserves the id across backend reads and repair writes, so concurrent publication of a same-id live session rejects and rolls back. HMR also adopts a live prefix without closing its active turn.
Repair applies only to cold sessions. For a live id, `SessionPersistence.load(id)` waits until the authoritative in-memory snapshot is durable and returns it only when balanced; an open live turn rejects rather than receiving synthetic interruption boundaries. HMR adopts a live prefix without closing its active turn.
`SessionPersistence.inspect(id)` is the observer counterpart to recovery: it returns a detached valid stored prefix without truncating a torn record, adding interruption closers, or publishing write state. Same-id serialization keeps it coherent with backend writes. Derived read models use `inspect`, never `load`, so observing a checkpointed open turn cannot mutate the log if live ownership begins concurrently.
`SessionPersistence.inspect(id)` constructs an immutable logical Session without publishing it or writing recovery. Cold inspection balances an interrupted turn in memory while leaving torn physical tails untouched; inspection of an already-live Session borrows its current immutable snapshot and may therefore contain an open turn. Coordinator-backed implementations retain the exact cold unpublished Session in a bounded LRU, so repeated history reads and a later `prepare(id)` share one read, decompression, validation, freeze, and Session construction. `prepare(id)` reserves the Session, commits pending repair, and returns a disposable publication handle; `load(id)` uses the same machinery to commit repair without publication. The [Session preparation decision](../../.agents/notes/implemented/architecture/2026-08-05-session-preparation.md) owns this lifecycle.

`SessionStore.prepare()` accepts ordinary creation options or fresh persistence graphs transferred through `RestoredSessionOptions`.

An operator-configured local runner must supply at least one `runnerFailureSignatures` entry for its own pre-exec refusal dialect; the provider adds outer-shell missing and unexecutable forms automatically. This makes an executable custom runner rejecting its profile distinguishable from the wrapped command exiting with the same status.
The [local provider](../../packages/sandbox/sandbox-local/README.md) owns operator configuration and maps its runner dialect into these rules. The [sandboxed bash consumer](../../packages/bash/bash-sandbox/README.md) owns spawn and result attribution.
## Provider and fail-closed errors
`ctx.sandbox.confine(argv, policy)` returns a `ConfinedArgv` or throws `SandboxUnavailableError` with code `SANDBOX_UNAVAILABLE` when no usable backend exists. A selected runner can also fail closed at execution time, in which case its failure signature carries the same infrastructure meaning. Silent unconfined passthrough is never legal for a confined policy.
`ctx.sandbox.confine(argv, policy)` returns a `ConfinedArgv` or throws `SandboxUnavailableError` with code `SANDBOX_UNAVAILABLE` when no usable backend exists. Consumers may also classify a failure while spawning or observing the returned argv; that attribution belongs to the consumer contract. Silent unconfined passthrough is never legal for a confined policy.
Provider probing arbitrates between multiple candidates and is cached for the provider lifetime. A platform with one candidate may select it directly; execution-time refusal retains the safety property. The local provider reports bwrap and Seatbelt as full and preserves the Landlock launcher's full/partial kernel verdict.

The context metadata of the route a request resolved to is separate logged state, appended beside `request/header` inside the same step and only when the provider, model, or capacity differs from the previous record. It stays outside `EpochHeader` because that type is the reconstruction contract compared field-wise by `headerEquals`: capacity describes a route, not a request input, so folding it in would let a capacity change register as a request-envelope `change` and would pull adapter metadata into the loop's reconstruction invariant. Like `request/header`, it is not a `SurfaceEventType` and produces no LLM message. `session.requestContext()` folds the latest record incrementally. A route whose adapter advertises no capacity is recorded with `contextWindow` absent, so the new record clears an older route's capacity.

An explicit `boundary` lets callers fork from any stable between-turn position, including a previous `turn/end` or a later standalone log-only event, even if the source has newer events or an open current turn. The API rejects a prefix that ends inside an open turn instead of clipping silently. Broader execution-relation sanity stays in the existing `dsh-invariants` plugin and persistence repair path rather than being duplicated in `fork()`. `dsh-subagent-fork` keeps its completed-prefix clipping because tool-time delegation usually starts while the parent turn is open; ordinary session branching should make the requested boundary explicit.

## Why a turn ended: `TurnEndReasonMap`
`aborted` is intentionally a coarse durable outcome: it records that cancellation interrupted the live turn, not which runtime caller requested it. The runtime-only caller vocabulary belongs to [`AgentCancelCause`](core.md#the-agent-handle); a future audit requirement would use a separate control-request event rather than overloading the terminal result.
`turn/start` has no trigger field. The entered `user/message` batch records what entered each step, `llm/retry` records request recovery, and idle injection remains pending until a waking delivery reaches a later pre-step. Live turns retain the typed [`AgentCancelCause`](core.md#the-agent-handle) that stopped the driver; persistence uses the additional `{ kind: 'legacy' }` cause only when importing a supported coarse cancellation record that did not store its caller.

Discovery forwards the step's abort signal through `SkillLookupOptions`. `catalogDescriptionMaxLength` is the consumer config for the description bound, with default `500` and integer minimum `3`.
Before each later model step, the consumer applies exact tool visibility and digests the exact rendered entries between the `<available_skills>` tags from a complete snapshot. It derives the comparison baseline from the same entries in the newest recognizable visible catalog message sourced by the plugin. A changed digest appends a durable full replacement through `agent.inject()`; deleting every skill appends an explicit empty replacement. Incomplete snapshots preserve the last-good model view. If compaction hides every historical catalog message, the next complete snapshot re-establishes the current catalog; an empty view with no prior catalog emits nothing. These catalog messages are session history, not World State.

工作流 seam:一个 agent智能体运行由模型编写的编排脚本SCRIPT,扇出 subagent。与 [subagent](subagent.md) 一样,它是**一项可选能力**,不属于 agent loop智能体循环主干因此其词汇定义在此处而非 [core.md](core.md)。与 subagent 注册表不同,它采用 bash 形态:每个上下文只有一个引擎实现提供 `ctx.workflows`;没有命名提供方注册表(第二个引擎是插件替换,而非共存)。

## 启动请求
调用方启动 run 时提的请求。普通工作流工具根据模型的 `{ script, meta, args }` 调用发起调用的 agent 构建;专用消费方还可以为该 run 选择一个引擎级 `subagentProvider` 并调低 `maxTotalAgents`,但脚本无法观察或替换这两项策略。`meta``args` 是普通 JSON 数据引擎会 `meta` 形状校验,并在任何内容运行前大声拒绝——绝不会通过求值脚本文本来获取它`parent` 是必填字段——脚本生成的每个子 agent 都归属于它cwd、谱系与深度通过 [subagent seam](subagent.md) 流转)。
