`scope/` is the one non-service package here: a dependency-free library (`createScope`/`scopeOf`/`scopeTarget`) the registries and the loop build per-agent scoping on — it sits below `session/` and `system-prompt/` in the module graph precisely so they can consume it without a cycle.
|
||||
`scope` supplies the shared scoping primitive. `agent` owns the public seam, while `agent-loop` is its default implementation; extension plugins depend on the seam so the driver remains swappable.
|
||||
|
||||
`agent-loop` is the one concrete implementation of the `agent` seam and lives here because it is the harness's default product loop. It runs each driver inside `ctx.agents.withInitiator()`. Extension plugins depend on `agent`, including when they need the initiating Agent, and never on `agent-loop` directly, so the loop stays swappable.
|
||||
|
||||
The default composition that wires this spine into a runnable agent lives in [`examples/agent-spine-demo`](../examples/agent-spine-demo/README.md): one bundle plugin that loads the control spine plus selected default capabilities (`timer` + `llm` + sessions + fallback session titles + system-prompt + tools + agents + invariants + the local [skill family](../skill/README.md) + `tool-bash` + workspace-context + `agent-loop`) and forwards `agent-loop`'s `agents` list as its own config. It sits in `examples/` — ready-to-run demo/reference bundles — not in `core/`: `core/` ships the swappable spine pieces, while a demo bundle picks one concrete composition of them and adds a front door.
|
||||
Runnable compositions belong to [`examples/agent-spine-demo`](../examples/agent-spine-demo/README.md); this group owns only the swappable spine pieces.

`scope/` 是此处唯一的非服务包:它是不含依赖的库(`createScope`/`scopeOf`/`scopeTarget`),注册表和循环基于它实现按 agent 分域。它在模块图中位于 `session/` 和 `system-prompt/` 之下,正是为了让二者可以消费它而不形成环。

`agent-loop` 是 `agent` seam 的唯一具体实现,位于此处是因为它就是 harness 的默认产品循环。它在 `ctx.agents.withInitiator()` 中运行每个驱动器。扩展插件依赖 `agent`,即使需要发起调用的 Agent 也是如此;它们绝不直接依赖 `agent-loop`,因此循环保持可替换。

### Chunk-row storage codec (`chunk-rows.ts`)
|
||||
|
||||
Providers stream token-sized deltas, so a raw log stores hundreds of `assistant/chunk` lines whose JSON envelopes dwarf their payloads. `packChunkRuns(events)` packs each run of ≥3 consecutive same-block delta chunks into one storage row — `text-chunks`, `reasoning-chunks`, or `tool-call-chunks` (bare slash-less tags: storage vocabulary, not `SessionEventMap` members) — and `decodeStorageRecord(value)` expands a parsed line back into its exact events (`seq0`/`time0` + per-member `dt` gaps reconstruct every `seq`/`time`). The encoder whitelists exact shapes and stores anything unrecognized verbatim; the decoder validates row-tagged values and throws on malformation. Owned here so the JSONL backend and the fixture readers (`dsh-llm-replay`, `dsh-acp-snapshot`) share one codec; the backend's default-enabled `packChunks` config controls writes only.
|
||||
The shared [storage codec](src/chunk-rows.ts) losslessly converts event sequences to compact rows and back. It preserves unrecognized events verbatim and rejects malformed encoded rows; persistence backends decide whether to enable packed writes.
|
||||
|
||||
### Surface types
|
||||
|
||||
- `SurfaceOp` — how an event entered the ordered surface: `'append'` (normal tail append) or `{ op: 'replace', start, end }` (replace entries from `start` through `end` inclusive — both must be valid surface seqs; `start === end` replaces one entry). Used by compaction to shadow old events without deleting them.
|
||||
- `SurfaceIntent` — `{ surfaceOp: SurfaceOp; sourceEventSeqs?: number[] }`, the required third parameter to `session.append()` for surface-eligible types.
|
||||
- `SessionSurface` — the readonly live `nodes` and `replaceGeneration` projection exposed by `session.surface`; candidate validation remains private to `Session`.
|
||||
- `foldSurface(events)` — replay the canonical surface contract into detached current event sequences and actual replacement ranges. The same pass rejects non-contiguous seqs, misplaced or malformed metadata, empty or duplicate provenance, non-earlier sources, invalid positional ranges, replacements that fail to cite every shadowed surface entry, and a `tool/result` replacement that changes anything except one current result's `content`; `SurfaceManager` shares the atomic transition while retaining only its incremental sequence cache. Its optional `baseSeq` folds a contiguous loaded window with absolute event sequences and no synthetic prefix; replacements must remain inside that window.
|
||||
- `isSurfaceEvent(event)` / `isSurfaceEligibleType(type)` — the first narrows a `SessionEvent` to a fully formed surface event; the second detects a surface-eligible event missing its marker when validating a seed or loaded log.
|
||||
- `isAppendSurfaceEvent(event)` / `isReplacementSurfaceEvent(event)` — split a formed surface event by marker variant. Append-origin events are the durable source for a human transcript, which is not the model-visible surface: a landed replacement shadows the range it summarizes, so projecting a transcript from `session.surface` erases conversation the reader already saw. Consumers that must send exactly what the model sees keep reading `session.surface`.
|
||||
This package owns ordered surface projection, replacement validation, replay, and the type guards that distinguish append-origin from replacement events. The [surface type catalog](../../../docs/core-data-structures/session.md#surface-types) owns the exact shapes and field semantics. A human transcript must project append-origin events rather than `session.surface`, because landed replacements shadow history the reader already saw; model-facing consumers continue to read `session.surface`.

### Extension points
|

|

- Persistence plugins: subscribe to `session/event` (write-behind) and drain on `session/flush` (awaited) and fiber dispose. A durable backend reads the log and reloads it into a live session; the metadata seam (`SessionHeader`, `session.header`) is what such a backend stores beside the log.
|
||||
- Replay/fork: `create(id, { seed })` validates and freezes a contiguous current-format log and rebuilds its surface; request headers require provider/model, assistant messages require provider/model provenance, and a coarse aborted outcome must contain only `{ kind: 'aborted' }` (legacy reason-bearing records are rejected). `fork(source, boundary?, childSessionId?)` selects a completed-turn prefix and records lineage.

- Compaction: `dsh-compact-basic` appends a `user/message` replacement for summary checkpoints, while `dsh-compact-tool-result-prune` appends a content-only `tool/result` replacement. Tool-pairing boundary policy and its cache belong to the [`dsh-compact` seam](../../compact/compact/README.md), while this package owns ordered surface membership, replacement validation, and `replaceGeneration`.

|
||||
共享的[存储编解码器](src/chunk-rows.ts)在事件序列与紧凑行之间无损转换。它会逐字保留无法识别的事件,并拒绝形态错误的编码行;是否启用打包写入由持久化后端决定。

- `SurfaceOp`:事件进入有序 surface 的方式,即 `'append'`(正常尾部追加)或 `{ op: 'replace', start, end }`(替换从 `start` 到 `end` 的条目,含两端;二者都必须是有效的 surface 序号;`start === end` 时替换一个条目)。压缩用它遮蔽旧事件而不删除它们。
|
||||

||||
- `SessionSurface`:实时只读 `nodes` 和 `replaceGeneration` 投影,由 `session.surface` 暴露;候选校验仍由 `Session` 私有。

||||
- `foldSurface(events)`:回放规范 surface 契约,得到脱离的当前事件序列与实际替换范围。同一趟处理会拒绝不连续序号、错位或畸形元数据、空或重复溯源信息、来源并非更早事件、无效位置范围,以及没有引用所有已遮蔽 surface 条目的替换。如果一个 `tool/result` 替换修改了当前某个结果的 `content` 之外的任何内容,也会被拒绝;`SurfaceManager` 共享该原子状态转换,但只保留自己的增量序列缓存。其可选 `baseSeq` 可使用绝对事件序号折叠连续的已加载窗口,而无需构造合成前缀;替换范围必须位于该窗口内。
|
||||
- `isSurfaceEvent(event)`/`isSurfaceEligibleType(type)`:前者将 `SessionEvent` 收窄为形态完整的 surface 事件;后者在校验种子或已加载日志时,检测缺少标记的可进入 surface 事件。
|
||||
- `isAppendSurfaceEvent(event)`/`isReplacementSurfaceEvent(event)`:按标记变体拆分形态完整的 surface 事件。追加来源的事件是人类可读记录(transcript)的持久来源,而该记录并非模型可见的 surface:已落地的替换会遮蔽它所概括的范围,因此从 `session.surface` 投影记录会抹掉读者已经看到的对话。必须准确发送模型所见内容的消费方仍继续读取 `session.surface`。

||||

`request/header` 记录非历史请求封装的完整规范快照,其原因为 `initial`、`resume` 或 `change`。其可选 `adapterDefaults` 映射会标记由精确模型解析填入的生效 `reasoningEffort` 或 `maxTokens` 值,使下一次请求提议能够将它们与显式对话设置区分开。`foldRequestHeader()` 选择最新快照;旧版增量事件和已移除的 `fallback` 原因会被拒绝。详见[可重建请求 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-05-reconstructable-requests.md)。

|
||||
- **`fork()` 仅在实时会话的稳定边界处切分**:所选前缀结束时不得有开放轮次,且源会话必须位于存储中;[fork API](../../../.agents/notes/implemented/feature/2026-06-30-session-store-fork-api.md) 不支持对已持久化但未加载的会话进行 fork。
