Extract a backend-agnostic `PersistenceCoordinator` into `dsh-session-persistence`. The coordinator owns the orchestration once; each first-party backend composes one (`new PersistenceCoordinator(ctx, this)`), implements a small `PersistenceBackend` hook interface, and delegates its four public service methods (`create`/`append`/`load`/`list`) to it.

Composition, not inheritance. The coordinator is a concrete class the backend holds, not a base class the backend extends. The Agent Note's risk — "a coordinator must not make unusual backends fight an inheritance hierarchy" — is avoided: a backend exposes only the hooks; it cannot reach the coordinator's private orchestration state, and the public `SessionPersistence` service shape is unchanged, so a third-party backend MAY still implement the abstract service directly without the coordinator at all.

The coordinator retires each live session from its `session/disposed` notification: it waits for that exact Session object's initialization, serializes a final drain, and then removes the owned state, buffer, and init entries. Failed drains retain their buffers for backend teardown to retry. Settled per-id chain tails remove themselves only when they are still the current tail, so a completion cannot erase a newer operation for the same id. Backend teardown unregisters the write-path listeners before awaiting all admitted retirements, remaining buffers, and chains, then closes the backend.

The coordinator adds one indirection, an opaque torn marker, and detached session-retirement tasks, but centralizes correctness-heavy orchestration previously duplicated by every backend. Session disposal remains an observe-only event, so the session owner does not await persistence retirement; the coordinator contains failures, preserves uncommitted buffers, and makes backend teardown the quiescence boundary. Its hook surface stays narrow: identity, adoption, and collision checks reuse `loadStored`; materialization stays atomic inside `appendBatch`; and listing bypasses the coordinator.

The literal types live in the [task data-structure catalog](../../../../docs/core-data-structures/tasks.md).

A model-facing producer exposes that committed id in its canonical success value, normally `{ kind: 'background', taskId }`; Native rendering may keep human-readable prose.

Once registration publishes the id, cancellation belongs to the task's own controller and the task runtime: later cancellation of the producing tool call must not kill the published task. `task_kill`, owner disposal, and service teardown request cancellation; foreground execution remains coupled to the call's `exec.signal`.

Reported tasks do not inject redundant completion notices. Listener failures are logged independently, do not stop later listeners, and are not awaited by waiters or teardown. When a snapshot carries `outputLimitBytes`, `dsh-tool-tasks` preserves UTF-8 boundaries and reuses an existing producer truncation marker rather than duplicating it. Reads reserve status suffixes and retain the output tail; completion notices reserve the stable `background task <id>` prefix and `task_output` instruction before truncating variable kind, label, status, detail, or the truncation marker itself, so the minimum PTY cap still identifies the task to collect. The task surface resolves the caller-visible producer cap in a prepended pre-execute listener before policy can deny or short-circuit dispatch, then applies it through the task definitions' last-mile `finalizeContent` callback so normalized tool errors, outer pipeline failures, and single-text policy results cannot escape the bound; deliberately structured multi-block policy results retain policy ownership of their shape and size.

# Agent Note: Unified session query service
|
||||
|

Status: implemented

English | [中文](2026-07-23-unified-session-query-service.zh.md)

## Problem
|
||||
|
||||
Exact reads, semantic filters, relationship traces, and full-text search operate on the same live-preferred session corpus. Exposing full-text search under a second context key makes consumers and app compositions treat one capability as two services, even though the SQLite implementation is the only backend-specific part.
|
||||
|
||||
The interface package already owns the shared record, filter, trace, search-request, cursor, and error contracts. A provider registry or coordinator would add runtime selection semantics unsupported by any current consumer.
|
||||
|
||||
## Decision
|
||||
|
||||
`SessionQueryService` is the single abstract service registered as `ctx.sessionQuery`. It concretely implements listing, title and event reads, surface reads, filtering, and relationship tracing through its backend-independent `SessionCorpus`. Its only abstract methods are `searchSessions()` and `searchEvents()`.
|
||||
|
||||
`SessionQuerySqlite` extends that service and is the sole concrete backend. One mounted instance therefore exposes every operation through `ctx.sessionQuery`; its inherited exact operations use the shared corpus implementation, while its SQLite-owned lifecycle observes sources, reconciles the derived FTS index, ranks matches, and owns cursor generations. The interface package has no standalone concrete plugin, search-provider registry, or second context key.
|
||||
|
||||
Backend configuration includes the inherited `readWindowMax` setting alongside its own index path, journal mode, page limits, and snippet limit. First-party apps that need session queries mount the SQLite backend and place its disposable index beside their configured persistence root.
|
||||
|
||||
This service topology supersedes the separate-key portion of the [exact query decision](../feature/2026-07-10-session-query-service.md) and [SQLite search decision](../feature/2026-07-10-sqlite-session-query-provider.md); their corpus, query, tokenizer, reconciliation, and safety decisions remain in force.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
- **Keep `ctx.sessionQuery` and `ctx.sessionSearch` separate** — rejected because both expose operations over one logical corpus, force consumers to discover two keys, and let apps accidentally mount only a partial query surface.
|
||||
- **Keep a concrete base service and let the SQLite plugin register or mutate two search methods** — rejected because method availability would depend on plugin order and teardown, and the service would need a provider registration protocol for one implementation.
|
||||
- **Move every query implementation into the SQLite package** — rejected because exact reads, filters, and traces require no index and are shared behavior that belongs with their provider-independent contracts.
|
||||
|
||||
## Consequences
|
||||
|
||||
Consumers inject one service and can combine exact and full-text operations without a second capability lookup. A production composition must choose a concrete backend even when one consumer currently calls only inherited exact methods; tests may use a minimal subclass when backend behavior is outside their scope.
|
||||
|
||||
The unified object deliberately retains two internal observation strategies: exact operations read authoritative live/persisted sources per call, while full-text operations reconcile a disposable index. Sharing the context key does not make the derived index authoritative or couple exact-read availability to an FTS query.
|
||||
|
||||
Unit coverage pins inherited and abstract behavior on one key, SQLite coverage exercises both operation families on the concrete backend, and the real Loader path verifies that one exported plugin registers the combined service.

# Agent Note: 统一会话查询服务
|
||||
|

Status: implemented

[English](2026-07-23-unified-session-query-service.md) | 中文
|
||||
|
||||
## 问题
|
||||
|
||||
精确读取、语义过滤、关系追踪与全文搜索都作用于同一个实时源优先的会话语料库。将全文搜索暴露在第二个上下文键下,会让消费方与应用组合把同一项查询功能视为两个服务,尽管只有 SQLite 实现是后端特有的部分。
|
||||
|
||||
接口包已经拥有共享的记录、过滤、追踪、搜索请求、游标与错误契约。提供方注册表或协调器会引入运行时选择语义,而目前没有任何消费方支持这种语义。
|
||||
|
||||
## 决策
|
||||
|
||||
`SessionQueryService` 是注册为 `ctx.sessionQuery` 的唯一抽象服务。它通过后端无关的 `SessionCorpus` 具体实现列表查询、标题与事件读取、表层读取、过滤和关系追踪。仅有 `searchSessions()` 与 `searchEvents()` 两个方法为抽象方法。
|
||||
|
||||
`SessionQuerySqlite` 扩展该服务,并且是唯一的具体后端。因此,一个挂载实例便可通过 `ctx.sessionQuery` 暴露全部操作;其继承的精确操作使用共享的语料库实现,而由 SQLite 管理的生命周期负责观察数据源、对齐派生 FTS 索引、对匹配项排序并管理游标代际。接口包不提供独立的具体插件、搜索提供方注册表或第二个上下文键。
|
||||
|
||||
后端配置除了自身的索引路径、日志模式、分页限制与文本片段长度上限外,还包含继承的 `readWindowMax` 设置。需要会话查询的第一方应用挂载 SQLite 后端,并将其可丢弃索引放在已配置的持久化根目录旁。
|
||||
|
||||
这一服务拓扑取代了[精确查询决策](../feature/2026-07-10-session-query-service.md)和 [SQLite 搜索决策](../feature/2026-07-10-sqlite-session-query-provider.md)中关于分离上下文键的部分;其中关于语料库、查询、分词器、对齐与安全性的决策仍然有效。
|
||||
|
||||
## 已考虑的替代方案
|
||||
|
||||
- **保留相互独立的 `ctx.sessionQuery` 与 `ctx.sessionSearch`**:不予采纳,因为二者都针对同一逻辑语料库提供操作,迫使消费方识别两个键,还可能让应用误挂载一组不完整的查询接口。
|
||||
- **保留具体的基础服务,再由 SQLite 插件注册或修改两个搜索方法**:不予采纳,因为方法是否可用将取决于插件顺序与资源释放时机,而且该服务需要为唯一的实现定义一套提供方注册协议。
|
||||
- **将所有查询实现移入 SQLite 包**:不予采纳,因为精确读取、过滤与追踪不需要索引,并且都属于应与提供方无关契约放在一起的共享行为。
|
||||
|
||||
## 后果
|
||||
|
||||
消费方只需注入一个服务,无需再次查找其他功能,便可组合精确操作与全文操作。生产环境的组合必须选择一个具体后端,即使当前某个消费方只调用继承的精确方法;如果后端行为不在测试范围内,测试可以使用最小子类。
|
||||
|
||||
统一后的对象有意保留两种内部观察策略:精确操作在每次调用时读取权威的实时源或持久化源,全文操作则使可丢弃索引与数据源对齐。共用上下文键不会让派生索引成为权威来源,也不会使精确读取的可用性依赖 FTS 查询。
|
||||
|
||||
单元测试在同一个键上同时固定继承实现与抽象方法的契约,SQLite 测试在具体后端上覆盖两类操作,真实 Loader 路径则验证单个导出的插件能够注册组合后的服务。
