+# Agent Note: Repository naming contract and pre-release rename ledger
+
+Status: proposed
+
+English | [中文](2026-08-11-repository-naming-contract-and-rename-ledger.zh.md)
+
+## Problem
+
+The repository has grown faster than some names. Several package names still describe the first implementation instead of the capability. Several classes use `Service` even when they are registries, runtimes, engines, controllers, or resolvers. Some `ctx` keys are singular for registries and plural for one engine. Some provider names say `local` when they use replaceable filesystem or subprocess services and can run in another execution world.
+
+These names are not harmless. A name tells a contributor where a responsibility starts and stops. `Store` suggests data access. `Registry` suggests registrations and lookup. `Runtime` suggests live execution and lifecycle. When one word is used for all three, callers cannot tell which object owns policy, work, or state without reading the implementation.
+
+The repository also uses `SDK` in two meanings. The supported Python and TypeScript clients use the JSON-RPC SDK protocol. The project as a whole is DeepSeek Harness, not an SDK project. The removed SDK project toolchain made the broad meaning obsolete, but current prose and names still preserve parts of it.
+
+This is the last pre-release point at which repository-wide renames are cheap. Keeping weak names would turn accidental vocabulary into a compatibility contract.
+
+## Proposal
+
+Apply the rename ledger in this note before the first tagged release. Change names only. Do not change package responsibilities, service boundaries, behavior, defaults, or data models in a rename change. If a name exposes a bad boundary, write a separate proposed Agent Note for that boundary change.
+
+Each accepted family rename is atomic. Update its directory, npm package name, imports, Cordis plugin name, `ctx` key, public types, directly coupled event or tool identifiers, configuration, tests, fixtures, examples, generated references, and current documentation where the ledger names those surfaces. Do not leave an alias, compatibility package, duplicate service key, dual event name, or fallback parser. The repository is pre-release and rejects the old name.
+
+Implementation can use more than one PR to keep review practical. One PR must not leave one family with two public vocabularies. The final state must satisfy the complete ledger.
+
+### Use `SDK` for one thing
+
+`SDK` means the JSON-RPC-based client/server protocol used by the supported Python and TypeScript SDKs. Keep `@deepseek-ai/dsh-sdk-client`, `@deepseek-ai/dsh-sdk-protocol`, and the wire identity `deepseek-harness-sdk-runtime`. Rename the JSON-RPC server into that family. Do not call DeepSeek Harness itself an SDK, and do not restore the removed project generator, launcher, helper, or launcher telemetry packages.
+
+This proposal partially supersedes two clauses in the [package-regrouping decision](../../implemented/architecture/2026-07-29-package-regrouping.md): the deferred target `@deepseek-ai/dsh-sdk-server` becomes `@deepseek-ai/dsh-sdk-jsonrpc-server`, and `SDK` no longer describes the repository as a whole. The [SDK project toolchain removal](../../implemented/simplification/2026-08-11-remove-sdk-project-toolchain.md) remains the owner of the deletion and of the decision to keep the runtime SDK stack.
+
+### Name the role that exists
+
+Use a common, concrete noun. Name the stable responsibility, not the first implementation, the current folder, or a possible future expansion. Do not add a word that carries no information. Do not shorten a name by deleting the word that distinguishes its scope.
+
+An interface package names the capability. An implementation package adds the mechanism, protocol, environment, or vendor that distinguishes that implementation. Use `local` only when same-host execution is part of the contract. Do not use it for a provider that happens to read local-looking paths through replaceable `ctx.fs` or starts work through replaceable `ctx.subprocess`.
+
+Use a singular `ctx` key for one engine, runtime, policy, controller, resolver, store, or current configuration. Use a plural key for a registry or a service that owns multiple named members. The class role and key number must agree. A plural key does not by itself make an object a registry; its operations and ownership do.
+
+Use `Service` only when no sharper role is honest. `GoalService` and `SessionTitleService` are valid retained names because each owns a domain service whose work is not accurately reduced to storage, registration, or one execution mechanism.
+
+### Role words are contracts
+
+| Word | Use it when | Do not use it when |
+|---|---|---|
+| `Controller` | The object accepts commands or user intent and changes one existing domain or presentation state. It coordinates a bounded state transition. | The object executes arbitrary work, owns a provider fleet, or only converts values for display. |
+| `Store` | The object owns one data set and mainly provides create, read, update, delete, snapshot, or subscription operations for that data. | It validates a state machine, arbitrates authority, dispatches work, owns provider precedence, or coordinates several domains. A map inside a class does not make the class a store. |
+| `Directory` | The object exposes entries for discovery or selection. Its consumer asks what choices exist and reads their metadata. | Producers register arbitrary implementations into it, or callers execute work through it. A directory can be backed by a registry, but the two faces are not the same. |
+| `Presenter` | The object is a pure conversion from domain values or tool arguments to render intent. It has no I/O, subscription, mutation, or lifecycle ownership. | It reads services, changes state, or controls when work runs. Those jobs belong to a controller or runtime. |
+| `Registry` | The object owns a dynamic set of named registrations. It defines lookup, duplicate or precedence rules, registration lifetime, and disposal. | The main caller contract is dispatch, execution, cancellation, policy enforcement, or orchestration. A runtime can contain a registry as an internal part. |
+| `Runtime` | The object runs live work. It owns dispatch, cancellation, provider coordination, or operation lifecycle across calls. | The object only stores records, returns a catalog, resolves one value, or holds configuration. `Runtime` is not a generic replacement for `Service`. |
+| `Resolver` | The object computes or locates one answer from supplied inputs, usually without owning the answer's lifecycle. | It owns a mutable collection or a long-running execution lifecycle. |
+| `Engine` | The object implements a domain algorithm or stateful execution model, such as workflow, compaction, or query evaluation. | It only selects a provider or forwards a request across a protocol boundary. |
+| `Policy` | The object decides what is allowed, selected, limited, or observed. | It performs the mechanism that the decision permits. Keep policy and executor names separate. |
+| `Executor` | The object runs an explicit request or resolved specification in one capability. | It owns a broad application lifecycle or a catalog of providers. |
+| `Gateway` | The object adapts a process, network, RPC, or API boundary and translates between the two sides. | It only registers same-process services or stores metadata. |
+| `Provider` | The object supplies one implementation of a capability definition. Add a mechanism or vendor qualifier when more than one provider can exist. | It is the capability definition, the registry of providers, or the consumer-facing runtime. |
+| `Backend` | The object implements a replaceable lower-level persistence, transport, or execution backend behind a defined interface. | It is a user-facing service or only a returned reference to one live object. |
+| `Handle` | The value is a reference to one live resource and controls or observes that resource. | The object creates and manages the whole resource pool. Do not use `Owner` or the vague `Resource` when `Handle` or a sharper manager role fits. |
+| `Config` | The object owns one resolved configuration value or one tightly bounded configuration record and its update contract. | It stores a general collection, executes work, or exposes unrelated settings. |
+| `Service` | The object owns a cohesive domain service whose authority cannot be stated honestly as one of the sharper roles above. | The name is used only because the class extends Cordis `Service`, or because choosing the real role takes more thought. |
+
+The practical tests are direct. If callers mainly call `register()` and receive a disposer, use `Registry`. If callers mainly call `run()`, `dispatch()`, `cancel()`, or `execute()`, use `Runtime`, `Engine`, or `Executor`. If callers mainly browse choices, use `Directory`. If the object only maps domain data to UI data, use `Presenter`. If it also changes state, it is not a presenter.
+
+### Use qualifiers that add information
+
+Keep a protocol or dialect name when it distinguishes implementations. Keep `Bash`, `Pwsh`, `JSON-RPC`, `SQLite`, `JSONL`, `OpenTelemetry`, `Claude Code`, and `E2B` where the implementation depends on that mechanism. Do not put `LLM` into a compaction backend name when every current backend already uses the LLM seam; `basic` is the honest neutral name until a more specific algorithm name exists.
+
+Do not invent a `process sandbox` concept. The current `sandbox` family already names its product responsibility, and the accepted sweep does not change that boundary.
+
+Use title case for initialisms inside PascalCase identifiers: `Ui`, `Llm`, `JsonRpc`, and `ApiProxy`. Use the conventional uppercase form in prose and package names where applicable: UI, LLM, JSON-RPC, and API. `Typert` is the exact product spelling in identifiers and prose; do not write `TypeRT`, `TypeRt`, or `Typert` with another internal split.
+
+Do not remove an intentional vendor qualifier to avoid repetition. `dsh-subagent-dsh-sdk` names the DeepSeek Harness SDK provider and avoids confusion with another SDK. Its private class becomes `SdkSubagentProvider` because the class also needs to say what it provides.
+
+### Put the rule in project documentation
+
+When the rename implementation lands, add the full role-word contract to the paired package-creation guide at `docs/cookbook/adding-a-package.md`. Add a short linked rule to `packages/AGENTS.md`. Update the terminology table and the root project description so `SDK` and `Typert` have one meaning. The Agent Note owns the rationale and rejected alternatives; the guide owns the rule contributors follow.
+
+## Rename ledger
+
+The tables list public and repository-wide names. Private local variables follow the new vocabulary when they refer to the same role. A retained low-level or product-visible name is stated where a broad replacement would be wrong.
+
+### Runtime SDK
+
+| Current | Proposed | Reason |
+|---|---|---|
+| `@deepseek-ai/dsh-jsonrpc` | `@deepseek-ai/dsh-sdk-jsonrpc-server` | It is the server half of the SDK protocol. `jsonrpc` alone names an encoding; `sdk-jsonrpc-server` gives the family, mechanism, and role. |
+| `HarnessSdkServer` | `HarnessSdkJsonRpcServer` | The class is one JSON-RPC server implementation, not every possible SDK server. |
+
+Keep `@deepseek-ai/dsh-sdk-client`, `@deepseek-ai/dsh-sdk-protocol`, and `deepseek-harness-sdk-runtime`. Exclude `@deepseek-ai/create-sdk`, `@deepseek-ai/dsh-scripts`, `@deepseek-ai/dsh-helper`, and `@deepseek-ai/dsh-telemetry`; the separate removal decision deletes them and their support graph.
+
+### Shell and terminal
+
+| Current | Proposed | Reason |
+|---|---|---|
+| `packages/bash/` | `packages/shell/` | The group contains the dialect-neutral executor seam, Bash and PowerShell implementations, environment support, and shell tools. |
+| `@deepseek-ai/dsh-bash`, `ctx.bash` | `@deepseek-ai/dsh-shell`, `ctx.shell` | PowerShell already implements this seam. The capability is shell execution, not Bash. |
+| Dialect-neutral `BashExecutor`, `BashExecRequest`, `BashExecSpec`, `BashProcess`, and `BashRunResult` names | `ShellExecutor`, `ShellExecRequest`, `ShellExecSpec`, `ShellProcess`, and `ShellRunResult` | These types cross both Bash and PowerShell implementations. Leaf types that describe Bash syntax or behavior keep `Bash`. |
+| `@deepseek-ai/dsh-bash-env`, `ctx.bashEnv`, `BashEnvRegistry` | `@deepseek-ai/dsh-shell-env`, `ctx.shellEnv`, `ShellEnvRegistry` | The environment registry is shared by Bash and PowerShell tools. |
+| `packages/pty/` | `packages/terminal/` | The package family owns persistent terminal sessions. Raw PTY allocation remains in the subprocess layer. |
+| `@deepseek-ai/dsh-pty`, `ctx.pty`, `PtyService` | `@deepseek-ai/dsh-terminal`, `ctx.terminals`, `TerminalSessionService` | Callers manage multiple named terminal sessions. They do not allocate raw PTYs through this service. |
+| Public high-level `Pty*` session and backend names | `Terminal*` names | The public abstraction is a terminal session. Keep low-level `SubprocessTerminal*` names because they already name the substrate. |
+| `@deepseek-ai/dsh-pty-local`, `LocalPtyBackend` | `@deepseek-ai/dsh-terminal-bash`, `BashTerminalBackend` | The provider depends on Bash prompt and shell behavior. `local` hides the actual dialect. |
+| `@deepseek-ai/dsh-tool-pty` | `@deepseek-ai/dsh-tool-terminal` | The model-facing tools are already `terminal_*`; the package should use the same product noun. |
+| `packages/pty/tool-bash-persistent` | `shell/tool-bash-persistent/` | The tool is a Bash tool and belongs with shell tools. Keep its npm name: `persistent` distinguishes it from one-shot `bash`, while `bash-terminal` would blur the product tool with the terminal-session family. |
+
+Keep the Bash- and PowerShell-specific leaf packages, plugin ids, types, and tools. Their dialect names are accurate.
+
+### Language server and jobs
+
+| Current | Proposed | Reason |
+|---|---|---|
+| `@deepseek-ai/dsh-lsp-local` | `@deepseek-ai/dsh-lsp-stdio` | The provider speaks LSP over stdio through replaceable filesystem and subprocess services. It is not necessarily local. |
+| `packages/tasks/` | `packages/jobs/` | The family owns detached tool jobs. `jobs` is short and avoids collision with user task or todo concepts. |
+| `@deepseek-ai/dsh-tasks`, `ctx.tasks`, `TaskService` | `@deepseek-ai/dsh-jobs`, `ctx.jobs`, `JobRegistry` | The service registers, owns, observes, waits for, and cancels multiple background jobs. It is a registry, not a general task service. |
+| Public `TaskId`, `TaskKindMap`, `TaskStart`, `TaskHooks`, `TaskOutcome`, `TaskSnapshot`, `TaskRead`, and `TaskDoneListener` names | Corresponding `Job*` names | These types belong to the renamed job domain. `JobId` is shorter and clearer than `BackgroundTaskId` or `BgTaskId`. |
+| `@deepseek-ai/dsh-tasks-local`, `LocalTaskService` | `@deepseek-ai/dsh-jobs-local`, `LocalJobRegistry` | This is the process-local provider of the job registry. Here `local` is meaningful because the jobs and callbacks live in one process. |
+| `@deepseek-ai/dsh-tool-tasks` | `@deepseek-ai/dsh-tool-jobs` | The consumer controls the job registry and should use the same domain noun. |
+| `task_output`, `task_list`, `task_kill` | `job_output`, `job_list`, `job_kill` | These model tools act on jobs, not user tasks. `run_in_background` returns a `JobId`. |
+
+Keep the base LSP package, `ctx.lsp`, LSP protocol types, and the LSP tool. The seam deliberately exposes language-server semantics; only its provider qualifier is wrong.
+
+### Input triggers, tool presentation, permission presets, and user questions
+
+| Current | Proposed | Reason |
+|---|---|---|
+| `@deepseek-ai/dsh-client-ui-slash`, `ui-slash/` | `@deepseek-ai/dsh-client-ui-input-trigger`, `ui-input-trigger/` | The client handles `/`, `@`, keyboard arbitration, candidate menus, and programmatic launch. It is not only slash commands. |
+| `ctx.slash`, `SlashService`, `SlashController`, `SlashSource` | `ctx.inputTriggers`, `InputTriggerService`, `InputTriggerController`, `InputTriggerSource` | The names cover every supported trigger and keep the existing service, controller, and source roles. Coupled locale and public type names follow `InputTrigger`. |
+| `@deepseek-ai/dsh-agent-tool-mode`, plugin `tool-mode` | `@deepseek-ai/dsh-agent-tool-presentation`, plugin `tool-presentation` | The plugin changes how tools are presented to the model. It does not change execution behavior. Keep local `Config.mode` and `ToolPresentationMode`. |
+| `packages/interaction/permission/` | `packages/interaction/permission-presets/` | The package owns named combinations of sandbox and approval settings, not permission enforcement. |
+| `@deepseek-ai/dsh-permission`, `ctx.permission`, `PermissionService` | `@deepseek-ai/dsh-permission-presets`, `ctx.permissionPresets`, `PermissionPresetService` | The service selects and persists presets. Sandbox and approval services enforce the result. |
+| `@deepseek-ai/dsh-client-ui-permission` | `@deepseek-ai/dsh-client-ui-permission-presets` | The UI edits and selects permission presets. |
+| `@deepseek-ai/dsh-user-interaction`, `user-interaction/` | `@deepseek-ai/dsh-user-questions`, `user-questions/` | The seam supports question batches and answers only. Approval, commands, and directory picking are separate interaction seams. |
+| `ctx.userInteraction`, `UserInteractionService`, `UserInteractionProvider`, `UserInteractionError` | `ctx.userQuestions`, `UserQuestionService`, `UserQuestionProvider`, `UserQuestionError` | These names state the one supported interaction shape. Keep `AskUserQuestion*`, the `ask_user_question` tool, and `@deepseek-ai/dsh-tool-ask-user`. |
+
+Keep `/permission`, the `permissions` projection, the `permission` settings namespace, and `permission/preset`; they are accurate product or durable vocabulary. Keep the full `PermissionPresetSettingsController` name. Dropping `Preset` would remove the word that limits its authority. Plan a separate proposal to remove the `both` tool-presentation mode; this rename does not remove behavior.
+
+### Typert, API gateway, and tools
+
+| Current | Proposed | Reason |
+|---|---|---|
+| `packages/typert/type-meta/`, `@deepseek-ai/dsh-type-meta` | `typert/protocol/`, `@deepseek-ai/dsh-typert-protocol` | The package owns the Typert Remote protocol, decorators, bindings, codecs, lookups, and context contracts. It is not generic type metadata. |
+| `GatewayService` in the protocol package | `TypertRemoteService` | The base class marks a same-process service for Remote export. It is not the API gateway. |
+| `bindTypeRTGateway`, `typertGateway` binding | `bindTypertRemote`, `typertRemote` | These bindings expose Typert Remote services, not the concrete API gateway service. |
+| Public `TypeRT*` and camel-case `typeRT*` identifiers | `Typert*` and `typert*` | `Typert` is the one canonical product spelling. |
+| Protocol interface `TypeRTService` | `TypertRegistry` | The interface registers and looks up Typert metadata. The concrete registry already uses this role. |
+| `ToolRegistry` | `ToolRuntime` | The class owns presentation, approval and guard policy, dispatch, cancellation, validation, finalization, and observation. Registration is only one internal part. |
+| `ToolRegistryScheduler`, `TOOL_REGISTRY_SCHEDULER` | `ToolRuntimeScheduler`, `TOOL_RUNTIME_SCHEDULER` | The scheduler controls runtime dispatch, not registration. |
+
+Keep `@deepseek-ai/dsh-tools` and `ctx.tools`. Keep `@deepseek-ai/dsh-api-gateway`, its `gateway/` folder, `ctx.typertGateway`, and `TypertGatewayService`; that service is a real API gateway. Its internal `TypeRT*` identifiers still follow the `Typert*` spelling rule.
+
+### Workspace instructions, telemetry, identity, and launch environment
+
+| Current | Proposed | Reason |
+|---|---|---|
+| `ctx.workspace` | `ctx.workspaces` | `WorkspaceRegistry` owns multiple workspaces. The plural key matches the registry role. Keep `@deepseek-ai/dsh-workspace`, `WorkspaceRegistry`, `Workspace`, and `workspace.*` wire names. |
+| `@deepseek-ai/dsh-workspace-context`, `context/workspace-context/` | `@deepseek-ai/dsh-agent-instructions`, `context/agent-instructions/` | The package loads hierarchical `AGENTS.md` and `CLAUDE.md` files for the agent. It is not general workspace context. |
+| Plugin and durable source names `workspace-context` and `workspace-instructions` | `agent-instructions` | The recorded source is a specific class of agent instructions. `AgentInstruction*` replaces public `WorkspaceInstruction*` names. This term does not include system, developer, or user messages. |
+| `ctx.telemetry`, abstract `Telemetry` | `ctx.sessionTelemetry`, `SessionTelemetryBackend` | The service captures session-ledger telemetry and hands it to a reporting backend. It is not a repository-wide metrics or tracing service. |
+| `TelemetryBackend` | `SessionTelemetrySink` | This lower layer receives emitted records. `Sink` distinguishes it from the coordinating backend service. |
+| `TelemetryCoordinator`, `TelemetryRecord`, `TelemetrySeverity`, `TelemetrySharingStatus`, and `TelemetryCapture` | Corresponding `SessionTelemetry*` names | These public types belong only to session telemetry. |
+| `telemetry/record` | `session-telemetry/record` | The event name must state its owning domain. |
+| `TelemetryOtel`, `TelemetryMode`, plugin `telemetry-otel` | `OpenTelemetrySessionBackend`, `SessionTelemetryMode`, plugin `session-telemetry-otel` | The provider name states both the OpenTelemetry mechanism and session scope. Keep the package names `dsh-session-telemetry` and `dsh-session-telemetry-otel`. |
+| `session/user-id/`, `@deepseek-ai/dsh-user-id` | `session/anonymous-user-id/`, `@deepseek-ai/dsh-anonymous-user-id` | The value is a random correlation id, not an authenticated user identity. |
+| `USER_ID_FILE_NAME`, `.userid`, feedback label `User` | `ANONYMOUS_USER_ID_FILE_NAME`, `.anonymous-user-id`, feedback label `Anonymous user` | The file and UI must not imply account identity. Keep the existing `AnonymousUserId` functions and the standard OTel attribute `user.id`. |
+| `util/environment/`, `@deepseek-ai/dsh-environment` | `util/launch-environment/`, `@deepseek-ai/dsh-launch-environment` | The package captures one immutable layered snapshot at launch. It is not a general environment API. |
+| Public `Environment*`, `createEnvironmentSnapshot`, `environmentOf`, `DSH_ENVIRONMENT_KEY` | `LaunchEnvironment*`, `createLaunchEnvironmentSnapshot`, `launchEnvironmentOf`, `DSH_LAUNCH_ENVIRONMENT_KEY` | The names state the snapshot's lifetime and purpose. |
+| `ctx.launcherEnvironment` | `ctx.launchEnvironment` | The value describes the application launch, not only a launcher component. Keep source labels `process`, `project-env`, and `user-env`. |
+
+### Workflow, goals, and compaction
+
+| Current | Proposed | Reason |
+|---|---|---|
+| `WorkflowService`, `ctx.workflows` | `WorkflowEngine`, `ctx.workflowEngine` | One engine parses and executes workflow programs. The plural key wrongly suggests a registry. Keep `@deepseek-ai/dsh-workflow` and workflow events and tools. |
+| `@deepseek-ai/dsh-workflow-workerthread`, `WorkerWorkflowEngine` | `@deepseek-ai/dsh-workflow-worker-thread`, `WorkerThreadWorkflowEngine` | `worker thread` is the precise Node mechanism and the repository spelling uses the full words. |
+| `@deepseek-ai/dsh-goal-session`, `goal/goal-session/` | `@deepseek-ai/dsh-goal-round-driver`, `goal/goal-round-driver/` | The plugin drives same-session Goal Rounds. It neither stores goals nor defines sessions. Keep `GoalService`, goal source, events, and contracts. |
+| `packages/compact/` | `packages/compaction/` | The group is a noun-domain family. `compact` remains the user command verb. |
+| `@deepseek-ai/dsh-compact`, `ctx.compact`, `CompactService` | `@deepseek-ai/dsh-compaction`, `ctx.compaction`, `CompactionEngine` | The object runs the compaction algorithm and lifecycle. It is an engine, not a generic service. |
+| `compact/*` events and public domain prefixes | `compaction/*` | Events and domain types use the noun. Keep verb-shaped operations such as `compactNow`, `compactRegion`, and `compactIfNeeded`. |
+| `@deepseek-ai/dsh-compact-basic`, `BasicCompactService`, public `BasicCompact*` | `@deepseek-ai/dsh-compaction-basic`, `BasicCompactionEngine`, corresponding `BasicCompaction*` | `basic` is plain but honest. `compaction-llm` adds no information because LLM use is already part of the current implementation family. |
+| `@deepseek-ai/dsh-compact-tool-result-prune`, `ToolResultPruneService`, `ctx.toolResultPrune` | `@deepseek-ai/dsh-compaction-tool-result-pruner`, `ToolResultPruner`, `ctx.toolResultPruner` | The plugin is an actor that prunes tool results. The noun `pruner` names that role. |
+
+Keep `/compact`, the command package, and the rejected decision to preserve separate compaction definition and provider packages. The rename changes vocabulary, not that package boundary.
+
+### Settings, credentials, client modules, and small core roles
+
+| Current | Proposed | Reason |
+|---|---|---|
+| Abstract `Settings` | `SettingsProvider` | The class supplies settings through a replaceable capability. Keep the package, key, and events. |
+| `@deepseek-ai/dsh-settings-local`, `SettingsLocal` | `@deepseek-ai/dsh-settings-file`, `FileSettingsProvider` | The implementation is file-backed through the filesystem seam. `file` states the mechanism; `local` does not. |
+| Abstract `Credentials` | `CredentialProvider` | The class resolves credential references. Keep package names, keys, and events. |
+| `CredentialsLocal` | `LocalCredentialProvider` | This provider reads the host process and `.env` state, so local execution is part of its contract. |
+| `ClientModuleHostService`, `ctx.clientModuleHost` | `ClientModuleRegistry`, `ctx.clientModules` | The service owns multiple registered client modules. Keep the package and the browser `ClientModuleLoader`. |
+| `AgentDefaultModelService` | `AgentDefaultModelConfig` | The object stores one default model selection. It does not run a service or general registry. Keep its package, key, settings namespace, and type. |
+| `SessionReferenceService`, `ctx.sessionReferences` | `SessionReferenceResolver`, `ctx.sessionReferenceResolver` | It resolves one session reference from a URI or input. It does not own a reference collection. |
+| `SessionQueryService`, `SessionQuerySqlite` | `SessionQueryEngine`, `SqliteSessionQueryEngine` | The classes execute a query model and its SQLite implementation. Keep package names, key, and tool. |
+| `CommandService` in the host command package | `CommandRuntime` | The object registers and executes host commands across live calls. Keep its package, key, types, and events. |
+| `TokenMeterService` | `TokenMeter` | The object measures token use. `Service` adds no scope. |
+| `LlmService` | `LlmRuntime` | The object selects providers and runs live model requests. Keep the package, key, adapters, and events. |
+
+### Host web server, session data, and code execution
+
+| Current | Proposed | Reason |
+|---|---|---|
+| `HttpServerService`, `ctx.httpServer` | `WebServer`, `ctx.webServer` | The server owns HTTP routes and WebSocket upgrade routes. `Web` leaves room for both; `Http` is too narrow here. Keep `packages/host/webserver`, `@deepseek-ai/dsh-host-webserver`, `WebRoute`, and `WebUpgradeRoute`. |
+| Documentation subsystem label `http-server` | `web-server` | The subsystem must use the same scope as the service. |
+| `SessionPersistenceJsonl` | `JsonlSessionPersistence` | Put the implementation qualifier first and keep the capability role intact. |
+| `SessionPersistenceSqlite` | `SqliteSessionPersistence` | Use the same provider naming order as JSONL. |
+| `@deepseek-ai/dsh-session-title-first-message-llm`, cadence `first-message` | `@deepseek-ai/dsh-session-title-first-prompt-llm`, cadence `first-prompt` | The trigger is the first user prompt, not any message in the session log. |
+| `@deepseek-ai/dsh-session-title-all-messages-llm`, cadence `all-user-messages` | `@deepseek-ai/dsh-session-title-all-prompts-llm`, cadence `all-prompts` | The backend refreshes from user prompts. `all messages` wrongly includes assistant and tool events. |
+| `@deepseek-ai/dsh-code-runtime-worker`, `WorkerCodeRuntime` | `@deepseek-ai/dsh-code-runtime-worker-thread`, `WorkerThreadCodeRuntime` | The implementation uses a Node worker thread. `worker` alone is too broad. |
+| `SubprocessService` | `SubprocessRuntime` | The service owns live child-process execution and lifecycle. Keep its package and key. |
+| `LocalSubprocessService` | `LocalSubprocessRuntime` | The provider runs same-host processes and process trees. |
+| `E2BSubprocessService` | `E2BSubprocessRuntime` | The provider runs subprocesses in the E2B runtime. |
+
+Keep the complete session projection family and `SessionProjection*` vocabulary. A projection is a maintained read model; `Reducer` would name only its fold operation and would understate caching and lookup. Keep `SessionTitleService`, checkpoint policy, persistence package names, time context, and tmux context.
+
+### Filesystem, skill, subagent, and web providers
+
+| Current | Proposed | Reason |
+|---|---|---|
+| `@deepseek-ai/dsh-fs-policy` | `@deepseek-ai/dsh-fs-observation-policy` | The package defines which filesystem observations authorize later effects. It is not the complete filesystem or sandbox policy. |
+| `FsPolicyExec` | `FsObservationActor` | The value names the actor whose observations and effects the policy relates. It does not execute the policy itself. |
+| `SkillService` | `SkillRegistry` | The service registers providers and resolves skills from their catalogs. |
+| `@deepseek-ai/dsh-skill-local`, `LocalSkillProvider`, provider id `local` | `@deepseek-ai/dsh-skill-filesystem`, `FileSystemSkillProvider`, provider id `filesystem` | The provider discovers skill files through `ctx.fs`, which can be local or remote. The mechanism is filesystem access, not locality. |
+| `SubagentService` | `SubagentRuntime` | The service selects providers and owns live spawn, resume, follow-up, cancellation, and settlement behavior. |
+| `@deepseek-ai/dsh-subagent-spawn`, `SpawnProvider` | `@deepseek-ai/dsh-subagent-spawn-in-process`, `SpawnInProcessProvider` | This provider starts a child agent in the current process. The configured provider id remains `spawn`. |
+| `@deepseek-ai/dsh-subagent-fork`, `ForkProvider` | `@deepseek-ai/dsh-subagent-fork-in-process`, `ForkInProcessProvider` | This provider forks an agent in the current process. The configured provider id remains `fork`. |
+| `@deepseek-ai/dsh-subagent-inprocess`, `subagent-inprocess/` | `@deepseek-ai/dsh-subagent-in-process-driver`, `subagent-in-process-driver/` | The package contains common in-process driving logic, not a third provider. |
+| Private `SdkProvider` in `dsh-subagent-dsh-sdk` | `SdkSubagentProvider` | The repeated package qualifier is intentional, and the class must say that it provides subagents through the SDK. |
+| `WebService`, `WebServiceConfig` | `WebRuntime`, `WebRuntimeConfig` | The object selects providers and runs live search and fetch operations. Keep the package, key, provider packages, and model tool. |
+| `@deepseek-ai/dsh-web-fetch-local`, `LocalFetchProvider`, `LocalFetchLimits`, provider id `local-http` | `@deepseek-ai/dsh-web-fetch-http`, `HttpFetchProvider`, `HttpFetchLimits`, provider id `http` | This provider performs direct HTTP fetches. `local` says where code happens to run, not which mechanism it provides. |
+
+Keep `@deepseek-ai/dsh-subagent-dsh-sdk`, its provider id `dsh-sdk`, external ACP, Codex, and Claude Code provider families, the subagent tool package names, the main filesystem package and backends, filesystem tools and events, and the skill badge and tool packages.
+
+### Hooks, guards, plan mode, extensions, and diagnostics
+
+| Current | Proposed | Reason |
+|---|---|---|
+| `@deepseek-ai/dsh-hooks-claude`, `ClaudeHookConfig`, `parseClaudeConfig`, dialect `claude` | `@deepseek-ai/dsh-hooks-claude-code`, `ClaudeCodeHookConfig`, `parseClaudeCodeConfig`, dialect `claude-code` | The hook bridge targets Claude Code, not every Anthropic or Claude product. |
+| `@deepseek-ai/dsh-repeat-tool-guard`, plugin/source `repeat-tool-guard` | `@deepseek-ai/dsh-repeat-tool-reminder`, plugin/source `repeat-tool-reminder` | The plugin adds a model reminder. It does not block or enforce a guard decision. |
+| `@deepseek-ai/dsh-timeout-policy` | `@deepseek-ai/dsh-tool-timeout-policy` | The policy applies to tool execution. The qualifier is more accurate than the earlier unsettled `timeout-guard` target. |
+| `PlanModeService` | `PlanModeController` | The object controls transitions into and out of plan mode. It is not a general execution runtime. |
+| `packages/self-modification/` | `packages/extensions/` | The group contains repository plugin inspection and mounting tools. `extensions` states the stable package role without asserting that the agent modifies itself. Keep the package names `tool-cordis` and repository-plugin names. |
+| `packages/support/` | `packages/test-support/` | The group is test-only infrastructure. Its path must say so. |
+| `packages/support/invariants/` | `runtime-diagnostics/invariants/` | Invariants can run in production diagnostics even though shipped presets omit them. They are not test support. |
+| `InvariantService` | `InvariantRegistry` | The object owns registered invariant checks. Keep `@deepseek-ai/dsh-invariants` and `ctx.invariants`. |
+| `packages/client/test-runtime/` | `packages/test-support/client-runtime/` | The package is client test infrastructure. Keep its npm name if it already states that contract. |
+
+Keep MCP, Todo, and the Plan Mode package, key, events, and tool names. The accepted change concerns the controller class, not the product feature.
+
+### Utilities, E2B, host, bundles, examples, and applications
+
+| Current | Proposed | Reason |
+|---|---|---|
+| `util/paths/`, `@deepseek-ai/dsh-paths` | `util/home-paths/`, `@deepseek-ai/dsh-home-paths` | The helpers resolve paths under the Harness home. They are not a general path library. Keep the individual function names when they already state the returned path. |
+| `util/retention/`, `@deepseek-ai/dsh-retention` | `util/output-retention/`, `@deepseek-ai/dsh-output-retention` | The policy retains command and tool output. It is not a general data-retention framework. |
+| `E2BSandboxService` | `E2BRuntime` | The class creates, reuses, and disposes the E2B execution environment used by filesystem and subprocess adapters. It is broader than one sandbox handle and narrower than a generic owner. Keep `@deepseek-ai/dsh-e2b`, `ctx.e2b`, and the `e2b/` group. |
+| `@deepseek-ai/dsh-frontend-static` | `@deepseek-ai/dsh-host-frontend-static` | The package is the Host plugin that serves the frontend assets. The prefix distinguishes it from frontend application code. |
+| `@deepseek-ai/dsh-jsonrpc-demo` | `@deepseek-ai/dsh-sdk-jsonrpc-demo` | The example demonstrates the runtime SDK over JSON-RPC. It belongs to the one SDK meaning. |
+| `@deepseek-ai/dsh-frontend` | `@deepseek-ai/dsh-web-frontend` | The application is the web frontend. Keep its physical `apps/web/` folder. |
+
+Keep atomic-write, brand, native-command, timeout utility, directory-picker, `dsh-base`, `dsh-web-app`, app boot, CLI names, and the `headless` package, bundle, and example identity. `headless` is the intended product essence and may later support more than one-shot execution.
+
+### Client runtime and UI
+
+| Current | Proposed | Reason |
+|---|---|---|
+| `SlotsService` | `SlotRegistry` | The object owns named slot declarations and registrations. |
+| `SessionsService` | `SessionRuntime` | The object owns live client session coordination, not a passive session list. |
+| `SessionHistoryService` | `SessionHistoryRegistry` | The object owns registered and loaded history entries. |
+| `WorkspacesService` | `WorkspaceRuntime` | The client object coordinates live workspace selection and operations. Existing `ctx` keys stay where the ledger does not name a key change. |
+| `LocaleService` | `LocaleRuntime` | The object coordinates locale definitions, selection, persistence, and change publication. |
+| `ThemeService` | `ThemeRuntime` | The object coordinates themes, preference resolution, system sensing, and change publication. |
+| `LayoutService` | `LayoutController` | The object controls the current UI layout state. |
+| `@deepseek-ai/dsh-client-ui-model` | `@deepseek-ai/dsh-client-ui-model-selection` | The package controls the model selection for a session. The singular `model` name is too broad. |
+| `ModelService`, `ctx.models` | `ModelDirectoryRegistry`, `ctx.modelDirectories` | The service registers multiple model directories. Each `ModelDirectory` remains the consumer-facing catalog of selectable models. |
+| `@deepseek-ai/dsh-client-ui-models` | `@deepseek-ai/dsh-client-ui-settings-models` | This package owns the Models settings panel. Keep `ModelsSettingsStore`; it holds one settings view model with data operations and subscriptions and is a real store. |
+| `@deepseek-ai/dsh-client-ui-plugin-config`, `client/ui-plugin-config/` | `@deepseek-ai/dsh-client-ui-settings-plugins`, `client/ui-settings-plugins/` | This package owns the Plugins settings section, not a general plugin-configuration system. The target joins the `ui-settings-*` family and uses the section's plural product name. |
+| `PluginConfigSection`, `PluginConfigSectionProps`, `PluginConfigSectionInjected`, `settings.pluginConfig` | `PluginsSettingsSection`, `PluginsSettingsSectionProps`, `PluginsSettingsSectionInjected`, `settings.plugins` | These names describe the Plugins settings presentation. Each card still edits one plugin's configuration, but the section itself is a settings UI. |
+| `agent-loop-store.ts`, `bash-store.ts`, `web-search-store.ts` | `agent-loop-card-controller.ts`, `bash-card-controller.ts`, `web-search-card-controller.ts` | Each module exports a card controller. A private `SnapshotStore` field does not make the module a store. |
+| `card-store.ts` | `card-form.ts` | The module owns the staged form, field conversion, and form actions. The snapshot stores it returns are presentation adapters, not the module's main role. |
+| `@deepseek-ai/dsh-client-ui-question` | `@deepseek-ai/dsh-client-ui-user-questions` | The UI presents the user-question seam, not an arbitrary question domain. |
+| `@deepseek-ai/dsh-client-ui-command`, `ui-command/` | `@deepseek-ai/dsh-client-ui-commands`, `ui-commands/` | The package presents and runs a collection of commands. |
+| Client `ctx.command`, `CommandService`, `CommandServiceContract` | `ctx.commandUi`, `CommandUiRuntime`, `CommandUiContract` | The host already owns `ctx.commands`. The client service is the UI runtime for command discovery and execution. Existing `CommandUiSpec` fixes the `Ui` casing. |
+| `ConversationService` | `ConversationController` | The object controls the active conversation state and user actions. |
+| `InputService` | `SessionInputResolver` | The interface resolves the input facade for one session scope. It is neither a global input registry nor an execution service. Keep `InputHub` as the concrete hub and `ctx.conversation.input` as the published face. |
+
+Use `Ui`, not `UI`, inside PascalCase identifiers. Keep the remaining client package names unless this ledger names them. Keep the deprecated client connection and Host `ApiProxy` vocabulary for now; the API plane will replace them, and a rename would add churn to a surface scheduled for removal.
+
+## Explicit non-renames
+
+The following debated names stay unchanged because the current scope is accurate or a rename would create a false concept:
+
+- Keep the complete sandbox family and `ctx.sandbox`. Do not introduce `processSandbox`.
+- Keep `@deepseek-ai/dsh-api-gateway`, `ctx.typertGateway`, and `TypertGatewayService`.
+- Keep session projection names. A projection is not only a reducer function.
+- Keep `GoalService`; it owns the goal state machine, authority, compare-and-set behavior, events, and remote operations. It is not just a store.
+- Keep `SessionTitleService`; its role is a domain service shared by title providers.
+- Keep `PermissionPresetSettingsController` even though it is long. Every word limits the role.
+- Keep `ModelsSettingsStore`; its main contract is one settings data model with store operations.
+- Keep `InputHub`; it is the concrete hub that backs `SessionInputResolver`.
+- Keep `dsh-subagent-dsh-sdk` and provider id `dsh-sdk`; the repeated qualifier prevents ambiguity.
+- Keep `headless`; the product identity is accurate even if the runtime later supports more than one-shot use.
+- Keep deprecated Host `ApiProxy` and client connection names until the API replacement removes them.
+- Keep `Web` for the Host server and the provider-neutral web capability. Use `HTTP` only for the direct fetch provider.
+- Keep `E2B`, not `E2B sandbox`, as the package and context name.
+- Keep MCP, Todo, directory picker, app boot, base bundle, web-app bundle, and CLI names.
+
+## Alternatives considered
+
+**Keep the current names and add a glossary.** Rejected. A glossary cannot make `BashExecutor` truthful when PowerShell implements it, or make `ToolRegistry` disclose that it enforces and executes tools. The identifier must carry the useful distinction.
+
+**Prefix every npm package with its group.** Rejected. Flat npm names do not need a copy of the directory tree. A mechanical prefix adds length without explaining the package role.
+
+**Call the whole repository an SDK.** Rejected. The project is an agent harness. SDK is the supported JSON-RPC client/server stack used by Python and TypeScript clients. Two meanings make package names and product prose ambiguous.
+
+**Use `Service` for every Cordis service class.** Rejected. Cordis inheritance is an implementation fact. The class name must tell callers whether the object registers, stores, resolves, controls, or runs work.
+
+**Use `Runtime` as the standard replacement for `Service`.** Rejected. `Runtime` is correct only when the object owns live execution or lifecycle. Registries, stores, directories, controllers, resolvers, engines, and configuration objects keep their sharper roles.
+
+**Prefer the shortest possible name.** Rejected. Short is useful only after scope is clear. `PermissionPresetSettingsController` keeps `Preset`; `JobId` is short because `Job` already carries the domain; `BgTaskId` is short but cryptic.
+
+**Use broad names for possible future features.** Rejected. Name the stable current role. A future boundary change can rename the object again before release or use a new proposal after release. Vague names charge every current reader for an unbuilt future.
+
+**Rename `dsh-compact-basic` to `dsh-compaction-llm`.** Rejected. `LLM` adds no distinction in the current backend family. `basic` is less ambitious and does not claim an algorithm that does not exist.
+
+**Rename session projections to reducers.** Rejected. Reduction is how a projection is built. The package also owns the read-model value, cache, and lookup contract.
+
+**Rename the persistent Bash tool to `bash-terminal`.** Rejected. That name collides with the terminal-session family. Moving `tool-bash-persistent` under `shell/` fixes its home while its current name continues to distinguish it from the one-shot Bash tool.
+
+**Rename or split boundaries while applying the ledger.** Rejected. Reviewers must be able to see that behavior did not change. A real boundary defect needs its own proposal, tests, and consequences.
+
+**Keep aliases for old names.** Rejected. No released consumer needs them. Aliases would preserve two vocabularies and make the first release carry a migration that never had a user.
+
+## Acceptance criteria
+
+- Every mapping in the ledger is applied, or this proposal is amended before implementation to explain a changed decision.
+- Each family has one public vocabulary. No compatibility package, re-export alias, duplicate `ctx` key, dual plugin id, dual event id, old tool alias, or fallback parser remains.
+- The change is rename-only. Runtime behavior, package boundaries, defaults, policy, durable semantics, and model behavior stay equivalent except where an identifier is itself visible.
+- Package directories, npm names, imports, manifests, TypeScript references and paths, Cordis config, plugin ids, service keys, events, tools, RPC names, persisted names named by the ledger, fixtures, snapshots, examples, generated catalogs, and current prose agree with the new vocabulary.
+- Current implemented Agent Notes are updated with factual name and path changes when the implementation lands. The package-regrouping note records `dsh-sdk-jsonrpc-server` and no longer calls the repository an SDK. Notes whose architectural decision remains current are not rewritten into new decisions.
+- The paired package-creation guide contains the role-word contract, `packages/AGENTS.md` links to it, the terminology table records the chosen words and `Typert` spelling, and root project prose calls the product DeepSeek Harness rather than DeepSeek Harness SDK.
+- The removed SDK project toolchain stays absent.
+- Focused tests cover each renamed family; source-plane typecheck, build, package hygiene, generated-reference gates, snapshots affected by visible identifiers, translation pairing, `doc-sync`, and lint pass on the complete implementation.
+- The proposed note moves to `implemented/` only after the full ledger and documentation contract are true. Its implementation form describes the final state, not a migration checklist.
+
+## Risks
+
+The sweep changes many imports, paths, configuration strings, generated references, and model-visible names. A missed string can compile but fail at load or replay time. Implementation must use both type-directed edits and exact old-name searches across source, config, tests, fixtures, docs, and generated inputs.
+
+Concurrent work will conflict with moved paths and renamed symbols. This is temporary pre-release cost. Splitting the implementation by coherent family can reduce review and merge conflicts, but each family must remain atomic.
+
+Some names will become longer. The extra word is intentional when it prevents a false claim about authority or mechanism. Long names are still a failure when every word does not constrain the role.
+
+The role vocabulary can become cargo cult if reviewers check suffixes without checking behavior. The guide must keep the direct tests in this note: inspect what callers do, what lifetime the object owns, and what failure or policy it controls.
+
+Old on-disk names, wire values, tool names, and configuration entries named in the ledger will stop working. This is accepted before release. The implementation must fail clearly on stale configuration where the owning parser can identify it; it must not silently accept both forms.

+# Agent Note: 仓库命名约定与预发布重命名清单
+
+Status: proposed
+
+[English](2026-08-11-repository-naming-contract-and-rename-ledger.md) | 中文
+
+## 问题
+
+仓库的发展速度超过了部分名称的演进速度。一些包名仍在描述最初的实现，而非所提供的能力。若干类即使实际承担注册表、运行时、引擎、控制器或解析器的职责，名称仍使用 `Service`。部分 `ctx` 键以单数命名注册表，却以复数命名单个引擎。还有一些提供方明明通过可替换的文件系统或子进程服务工作，可以在另一执行环境中运行，名称却使用 `local`。
+
+这些名称并非无关紧要。名称会告诉贡献者一项职责从哪里开始、到哪里结束。`Store` 表示数据访问。`Registry` 表示注册与查找。`Runtime` 表示实时执行和生命周期。如果同一个词同时表示这三者，调用方就必须阅读实现，才能判断哪个对象拥有策略、工作或状态。
+
+仓库还在两种含义下使用 `SDK`。受支持的 Python 和 TypeScript 客户端使用 JSON-RPC SDK 协议。项目整体是 DeepSeek Harness，而不是 SDK 项目。已移除的 SDK 项目工具链使宽泛的含义失去依据，但现有文案和名称仍保留了部分旧用法。
+
+这是首次发布带标签版本之前，最后一个能够低成本完成仓库级重命名的时点。保留含义不清的名称，会让偶然形成的词汇变成兼容性约定。
+
+## 提案
+
+在首次发布带标签版本之前，应用本说明中的重命名清单。只更改名称，不得在重命名变更中改变包职责、服务边界、行为、默认值或数据模型。如果某个名称暴露出不合理的边界，应另写一份 proposed Agent Note，专门提议边界变更。
+
+每组获准的系列重命名都必须原子完成。清单点名某一表面时，应一并更新其目录、NPM 包名、导入、Cordis 插件名称、`ctx` 键、公开类型、直接耦合的事件或工具标识符、配置、测试、fixture（测试前置数据）、示例、生成的参考资料以及当前文档。不得留下别名、兼容包、重复的服务键、双重事件名称或回退解析器。仓库尚未发布，旧名称应被拒绝。
+
+实现可以拆分为多个 PR（Pull Request），以保持评审可行。任何一个 PR 都不得让同一系列同时存在两套公开词汇。最终状态必须满足完整清单。
+
+### `SDK` 只表示一件事
+
+`SDK` 表示受支持的 Python 和 TypeScript SDK 所使用、基于 JSON-RPC 的客户端／服务器协议。保留 `@deepseek-ai/dsh-sdk-client`、`@deepseek-ai/dsh-sdk-protocol` 和协议身份 `deepseek-harness-sdk-runtime`。将 JSON-RPC 服务器重命名并纳入该系列。不得将 DeepSeek Harness 本身称为 SDK，也不得恢复已移除的项目生成器、启动器、辅助工具或启动器遥测包。
+
+本提案部分取代[包重新分组决策](../../implemented/architecture/2026-07-29-package-regrouping.md)中的两项约定：暂定目标 `@deepseek-ai/dsh-sdk-server` 改为 `@deepseek-ai/dsh-sdk-jsonrpc-server`，并且 `SDK` 不再描述整个仓库。[移除 SDK 项目工具链](../../implemented/simplification/2026-08-11-remove-sdk-project-toolchain.md)仍负责说明删除范围，以及保留运行时 SDK 栈的决策。
+
+### 按实际职责命名
+
+使用常见且具体的名词。名称应描述稳定职责，而不是最初的实现、当前目录或未来可能出现的扩展。不得添加不传递任何信息的词。不得为了缩短名称而删除用于限定作用域的词。
+
+接口包以能力命名。实现包增加机制、协议、环境或供应商限定词，以区分不同实现。只有同主机执行属于约定时，才能使用 `local`。如果提供方只是通过可替换的 `ctx.fs` 读取看似本地的路径，或通过可替换的 `ctx.subprocess` 启动工作，就不得使用该词。
+
+如果对象是单个引擎、运行时、策略、控制器、解析器、存储或当前配置，使用单数 `ctx` 键。如果对象是注册表，或服务拥有多个具名成员，使用复数键。类的职责和键的单复数必须一致。复数键本身不能证明对象是注册表；应由其操作和所有权决定。
+
+仅当没有更精确的职责词能够如实描述对象时，才使用 `Service`。`GoalService` 和 `SessionTitleService` 是保留的有效名称，因为它们各自拥有领域服务，其工作无法准确归约为存储、注册或单一执行机制。
+
+### 职责词即约定
+
+| 词 | 适用场景 | 不适用场景 |
+|---|---|---|
+| `Controller` | 对象接受命令或用户意图，并更改一项已有的领域状态或呈现状态。它协调有界的状态转换。 | 对象执行任意工作、管理一组提供方，或仅将值转换为显示形式。 |
+| `Store` | 对象拥有一组数据，主要对这些数据提供创建、读取、更新、删除、快照或订阅操作。 | 对象验证状态机、行使裁决权、分派工作、决定提供方优先级，或协调多个领域。类内部存在映射并不会让该类成为存储。 |
+| `Directory` | 对象公开条目，供发现或选择。消费方会查询有哪些选项，并读取其元数据。 | 生产方可向其中注册任意实现，或调用方通过它执行工作。目录可以由注册表支撑，但两者的对外职责并不相同。 |
+| `Presenter` | 对象只负责将领域值或工具参数转换为渲染意图。它不拥有 I/O、订阅、变更或生命周期。 | 对象读取服务、更改状态或控制工作运行时机。这些职责属于控制器或运行时。 |
+| `Registry` | 对象拥有一组动态的具名注册项。它定义查找规则、重复项或优先级规则、注册生命周期和资源释放。 | 调用方的主要约定是分派、执行、取消、策略执行或编排。运行时可以在内部包含注册表。 |
+| `Runtime` | 对象运行实时工作。它跨调用拥有分派、取消、提供方协调或操作生命周期。 | 对象只存储记录、返回目录、解析单个值或保存配置。`Runtime` 不是 `Service` 的通用替代词。 |
+| `Resolver` | 对象根据所提供的输入计算或定位一个答案，通常不拥有答案的生命周期。 | 对象拥有可变集合或长时间运行的执行生命周期。 |
+| `Engine` | 对象实现领域算法或有状态执行模型，例如工作流、压缩或查询求值。 | 对象只选择提供方，或跨协议边界转发请求。 |
+| `Policy` | 对象决定允许、选择、限制或观察什么。 | 对象执行决策所允许的机制。策略和执行器必须分别命名。 |
+| `Executor` | 对象在一项能力内运行明确的请求或已解析的规范。 | 对象拥有宽泛的应用生命周期或提供方目录。 |
+| `Gateway` | 对象适配进程、网络、RPC 或 API 边界，并在两侧之间转换。 | 对象只注册同进程服务或存储元数据。 |
+| `Provider` | 对象为一项能力定义提供一种实现。如果可以存在多个提供方，应增加机制或供应商限定词。 | 对象是能力定义、提供方注册表或面向消费方的运行时。 |
+| `Backend` | 对象在已定义接口之后，实现可替换的底层持久化、传输或执行后端。 | 对象是面向用户的服务，或只是对某个实时对象返回的引用。 |
+| `Handle` | 该值是对一个实时资源的引用，并控制或观察该资源。 | 对象创建并管理整个资源池。不得使用 `Owner` 或含义模糊的 `Resource`；如果 `Handle` 或更精确的管理职责合适，就应采用后者。 |
+| `Config` | 对象拥有一个已解析的配置值，或一份边界严格受限的配置记录及其更新约定。 | 对象存储通用集合、执行工作或公开不相关的设置。 |
+| `Service` | 对象拥有一项职责内聚的领域服务，且以上更精确的职责词都无法如实描述其职责范围。 | 仅因为类继承自 Cordis `Service` 而使用该名称，或因为确定真正的职责需要进一步思考。 |
+
+实用判断方式很直接。如果调用方主要调用 `register()` 并收到资源释放函数，应使用 `Registry`。如果调用方主要调用 `run()`、`dispatch()`、`cancel()` 或 `execute()`，应使用 `Runtime`、`Engine` 或 `Executor`。如果调用方主要浏览选项，应使用 `Directory`。如果对象只将领域数据映射为 UI 数据，应使用 `Presenter`。如果它还会更改状态，就不是呈现器。
+
+### 使用能够补充信息的限定词
+
+如果协议或方言名称能够区分实现，就应保留。实现依赖相应机制时，保留 `Bash`、`Pwsh`、`JSON-RPC`、`SQLite`、`JSONL`、`OpenTelemetry`、`Claude Code` 和 `E2B`。每个当前后端都已使用 LLM（大语言模型）seam 时，不要在压缩后端名称中加入 `LLM`；在出现更具体的算法名称之前，`basic` 才是如实且中性的名称。
+
+不得虚构 `process sandbox` 概念。当前 `sandbox` 系列已经准确命名其产品职责，获准的整体重命名不会改变该边界。
+
+PascalCase 标识符中的首字母缩略词使用首字母大写格式：`Ui`、`Llm`、`JsonRpc` 和 `ApiProxy`。在文案和适用的包名中使用惯例规定的全大写形式：UI、LLM、JSON-RPC 和 API。`Typert` 是标识符和文案中的唯一准确产品拼写；不得写成 `TypeRT`、`TypeRt`，也不得对 `Typert` 作其他内部拆分。
+
+不得为了避免重复而删除有意保留的供应商限定词。`dsh-subagent-dsh-sdk` 表示 DeepSeek Harness SDK 提供方，可避免与其他 SDK 混淆。其私有类改名为 `SdkSubagentProvider`，因为类名还需要说明它提供什么。
+
+### 将规则写入项目文档
+
+重命名实现合入时，应将完整的职责词约定加入配对的包创建指南 `docs/cookbook/adding-a-package.md`。在 `packages/AGENTS.md` 中添加一条简短规则并链接到该指南。更新术语表和根项目说明，使 `SDK` 和 `Typert` 各自只有一种含义。Agent Note 负责记录理由和被否决的替代方案；指南负责记录贡献者应遵循的规则。
+
+## 重命名清单
+
+以下表格列出公开名称和仓库级名称。引用相同职责的私有局部变量也应采用新词汇。若宽泛替换并不正确，清单会明确指出保留的底层名称或产品可见名称。
+
+### 运行时 SDK
+
+| 当前名称 | 提议名称 | 理由 |
+|---|---|---|
+| `@deepseek-ai/dsh-jsonrpc` | `@deepseek-ai/dsh-sdk-jsonrpc-server` | 它是 SDK 协议的服务器端。单独使用 `jsonrpc` 只说明编码；`sdk-jsonrpc-server` 则同时说明所属系列、机制和职责。 |
+| `HarnessSdkServer` | `HarnessSdkJsonRpcServer` | 该类是 JSON-RPC 服务器的一种实现，并不代表所有可能的 SDK 服务器。 |
+
+保留 `@deepseek-ai/dsh-sdk-client`、`@deepseek-ai/dsh-sdk-protocol` 和 `deepseek-harness-sdk-runtime`。排除 `@deepseek-ai/create-sdk`、`@deepseek-ai/dsh-scripts`、`@deepseek-ai/dsh-helper` 和 `@deepseek-ai/dsh-telemetry`；单独的移除决策负责删除这些包及其支撑依赖图。
+
+### Shell 与终端
+
+| 当前名称 | 提议名称 | 理由 |
+|---|---|---|
+| `packages/bash/` | `packages/shell/` | 该组包含方言无关的执行器 seam、Bash 和 PowerShell 实现、环境支持以及 shell 工具。 |
+| `@deepseek-ai/dsh-bash`, `ctx.bash` | `@deepseek-ai/dsh-shell`, `ctx.shell` | PowerShell 已经实现该 seam。此项能力是 shell 执行，而不是 Bash。 |
+| 方言无关的 `BashExecutor`、`BashExecRequest`、`BashExecSpec`、`BashProcess` 和 `BashRunResult` 名称 | `ShellExecutor`、`ShellExecRequest`、`ShellExecSpec`、`ShellProcess` 和 `ShellRunResult` | 这些类型横跨 Bash 和 PowerShell 实现。描述 Bash 语法或行为的叶层类型保留 `Bash`。 |
+| `@deepseek-ai/dsh-bash-env`, `ctx.bashEnv`, `BashEnvRegistry` | `@deepseek-ai/dsh-shell-env`, `ctx.shellEnv`, `ShellEnvRegistry` | Bash 和 PowerShell 工具共享该环境注册表。 |
+| `packages/pty/` | `packages/terminal/` | 该包系列负责持久终端会话。原始 PTY 分配仍位于子进程层。 |
+| `@deepseek-ai/dsh-pty`, `ctx.pty`, `PtyService` | `@deepseek-ai/dsh-terminal`, `ctx.terminals`, `TerminalSessionService` | 调用方管理多个具名终端会话，而不是通过该服务分配原始 PTY。 |
+| 公开的高层 `Pty*` 会话和后端名称 | `Terminal*` 名称 | 公开抽象是终端会话。保留底层 `SubprocessTerminal*` 名称，因为它们已经说明底层机制。 |
+| `@deepseek-ai/dsh-pty-local`, `LocalPtyBackend` | `@deepseek-ai/dsh-terminal-bash`, `BashTerminalBackend` | 该提供方依赖 Bash 提示符和 shell 行为。`local` 隐藏了实际方言。 |
+| `@deepseek-ai/dsh-tool-pty` | `@deepseek-ai/dsh-tool-terminal` | 面向模型的工具已使用 `terminal_*`；包应采用相同的产品名词。 |
+| `packages/pty/tool-bash-persistent` | `shell/tool-bash-persistent/` | 该工具是 Bash 工具，应与 shell 工具放在一起。保留其 NPM 名称：`persistent` 将它与一次性 `bash` 区分开来，而 `bash-terminal` 会混淆产品工具与终端会话系列。 |
+
+保留 Bash 和 PowerShell 专用的叶层包、插件 id、类型和工具。这些方言名称准确无误。
+
+### 语言服务器与作业
+
+| 当前名称 | 提议名称 | 理由 |
+|---|---|---|
+| `@deepseek-ai/dsh-lsp-local` | `@deepseek-ai/dsh-lsp-stdio` | 该提供方通过可替换的文件系统和子进程服务，以 stdio 传输 LSP。它不一定在本地运行。 |
+| `packages/tasks/` | `packages/jobs/` | 该系列负责脱离前台运行的工具作业。`jobs` 简短，并可避免与用户任务或 todo 概念冲突。 |
+| `@deepseek-ai/dsh-tasks`, `ctx.tasks`, `TaskService` | `@deepseek-ai/dsh-jobs`, `ctx.jobs`, `JobRegistry` | 该服务注册、拥有、观察、等待并取消多个后台作业。它是注册表，而不是通用任务服务。 |
+| 公开的 `TaskId`、`TaskKindMap`、`TaskStart`、`TaskHooks`、`TaskOutcome`、`TaskSnapshot`、`TaskRead` 和 `TaskDoneListener` 名称 | 对应的 `Job*` 名称 | 这些类型属于重命名后的作业领域。`JobId` 比 `BackgroundTaskId` 或 `BgTaskId` 更短、更清晰。 |
+| `@deepseek-ai/dsh-tasks-local`, `LocalTaskService` | `@deepseek-ai/dsh-jobs-local`, `LocalJobRegistry` | 这是作业注册表的进程内提供方。此处的 `local` 有明确含义，因为作业和回调都存在于同一进程。 |
+| `@deepseek-ai/dsh-tool-tasks` | `@deepseek-ai/dsh-tool-jobs` | 消费方控制作业注册表，应使用相同的领域名词。 |
+| `task_output`, `task_list`, `task_kill` | `job_output`, `job_list`, `job_kill` | 这些模型工具操作的是作业，而不是用户任务。`run_in_background` 返回 `JobId`。 |
+
+保留基础 LSP 包、`ctx.lsp`、LSP 协议类型和 LSP 工具。该 seam 有意公开语言服务器语义；错误的只有提供方限定词。
+
+### 输入触发器、工具呈现、权限预设和用户问题
+
+| 当前名称 | 提议名称 | 理由 |
+|---|---|---|
+| `@deepseek-ai/dsh-client-ui-slash`, `ui-slash/` | `@deepseek-ai/dsh-client-ui-input-trigger`, `ui-input-trigger/` | 客户端处理 `/`、`@`、键盘仲裁、候选菜单和程序化启动，并非只处理斜杠命令。 |
+| `ctx.slash`、`SlashService`、`SlashController`、`SlashSource` | `ctx.inputTriggers`、`InputTriggerService`、`InputTriggerController`、`InputTriggerSource` | 这些名称覆盖所有受支持的触发器，并保留现有的服务、控制器和来源职责。耦合的区域设置和公开类型名称也改用 `InputTrigger`。 |
+| `@deepseek-ai/dsh-agent-tool-mode`，插件 `tool-mode` | `@deepseek-ai/dsh-agent-tool-presentation`，插件 `tool-presentation` | 该插件改变工具向模型呈现的方式，而不改变执行行为。保留局部 `Config.mode` 和 `ToolPresentationMode`。 |
+| `packages/interaction/permission/` | `packages/interaction/permission-presets/` | 该包拥有沙箱与审批设置的具名组合，而不负责执行权限。 |
+| `@deepseek-ai/dsh-permission`, `ctx.permission`, `PermissionService` | `@deepseek-ai/dsh-permission-presets`, `ctx.permissionPresets`, `PermissionPresetService` | 该服务选择并持久化预设。沙箱和审批服务负责执行结果。 |
+| `@deepseek-ai/dsh-client-ui-permission` | `@deepseek-ai/dsh-client-ui-permission-presets` | UI 编辑和选择权限预设。 |
+| `@deepseek-ai/dsh-user-interaction`, `user-interaction/` | `@deepseek-ai/dsh-user-questions`, `user-questions/` | 该 seam 仅支持批量问题和答案。审批、命令和目录选择属于其他交互 seam。 |
+| `ctx.userInteraction`, `UserInteractionService`, `UserInteractionProvider`, `UserInteractionError` | `ctx.userQuestions`, `UserQuestionService`, `UserQuestionProvider`, `UserQuestionError` | 这些名称说明唯一受支持的交互形态。保留 `AskUserQuestion*`、`ask_user_question` 工具和 `@deepseek-ai/dsh-tool-ask-user`。 |
+
+保留 `/permission`、`permissions` 投影、`permission` 设置命名空间和 `permission/preset`；它们都是准确的产品词汇或持久化词汇。保留完整名称 `PermissionPresetSettingsController`。删除 `Preset` 会去掉限定其权限的词。另行制定提案以移除 `both` 工具呈现模式；本次重命名不移除行为。
+
+### Typert、API 网关与工具
+
+| 当前名称 | 提议名称 | 理由 |
+|---|---|---|
+| `packages/typert/type-meta/`, `@deepseek-ai/dsh-type-meta` | `typert/protocol/`, `@deepseek-ai/dsh-typert-protocol` | 该包拥有 Typert Remote 协议、装饰器、绑定、编解码器、查找逻辑和上下文约定。它不是通用类型元数据。 |
+| 协议包中的 `GatewayService` | `TypertRemoteService` | 该基类标记要导出为 Remote 的同进程服务。它不是 API 网关。 |
+| `bindTypeRTGateway`、`typertGateway` 绑定 | `bindTypertRemote`、`typertRemote` | 这些绑定公开 Typert Remote 服务，而非具体的 API 网关服务。 |
+| 公开的 `TypeRT*` 标识符和小驼峰形式的 `typeRT*` 标识符 | `Typert*` 和 `typert*` | `Typert` 是唯一规范的产品拼写。 |
+| 协议接口 `TypeRTService` | `TypertRegistry` | 该接口注册并查找 Typert 元数据。具体注册表已采用这一职责名。 |
+| `ToolRegistry` | `ToolRuntime` | 该类拥有呈现、审批与防护策略、分派、取消、验证、终结和观察。注册只是内部组成部分。 |
+| `ToolRegistryScheduler`, `TOOL_REGISTRY_SCHEDULER` | `ToolRuntimeScheduler`, `TOOL_RUNTIME_SCHEDULER` | 调度器控制运行时分派，而不是注册。 |
+
+保留 `@deepseek-ai/dsh-tools` 和 `ctx.tools`。保留 `@deepseek-ai/dsh-api-gateway`、其 `gateway/` 目录、`ctx.typertGateway` 以及 `TypertGatewayService`；该服务是真正的 API 网关。其内部的 `TypeRT*` 标识符仍应遵循 `Typert*` 拼写规则。
+
+### 工作区指令、遥测、身份和启动环境
+
+| 当前名称 | 提议名称 | 理由 |
+|---|---|---|
+| `ctx.workspace` | `ctx.workspaces` | `WorkspaceRegistry` 拥有多个工作区。复数键与注册表职责一致。保留 `@deepseek-ai/dsh-workspace`、`WorkspaceRegistry`、`Workspace` 和 `workspace.*` 协议名称。 |
+| `@deepseek-ai/dsh-workspace-context`, `context/workspace-context/` | `@deepseek-ai/dsh-agent-instructions`, `context/agent-instructions/` | 该包为 agent（智能体）加载分层的 `AGENTS.md` 和 `CLAUDE.md` 文件。它并非通用工作区上下文。 |
+| 插件名称和持久来源名称 `workspace-context` 与 `workspace-instructions` | `agent-instructions` | 记录的来源是一类具体的 agent 指令。以 `AgentInstruction*` 替换公开的 `WorkspaceInstruction*` 名称。该术语不包括系统消息、开发者消息或用户消息。 |
+| `ctx.telemetry`、抽象类 `Telemetry` | `ctx.sessionTelemetry`、`SessionTelemetryBackend` | 该服务捕获会话账本遥测，并交给报告后端。它不是仓库级指标或追踪服务。 |
+| `TelemetryBackend` | `SessionTelemetrySink` | 该底层接收已发出的记录。`Sink` 用于将它与协调型后端服务区分开。 |
+| `TelemetryCoordinator`、`TelemetryRecord`、`TelemetrySeverity`、`TelemetrySharingStatus` 和 `TelemetryCapture` | 对应的 `SessionTelemetry*` 名称 | 这些公开类型只属于会话遥测。 |
+| `telemetry/record` | `session-telemetry/record` | 事件名称必须说明所属领域。 |
+| `TelemetryOtel`、`TelemetryMode`，插件 `telemetry-otel` | `OpenTelemetrySessionBackend`、`SessionTelemetryMode`，插件 `session-telemetry-otel` | 提供方名称同时说明 OpenTelemetry 机制和会话作用域。保留包名 `dsh-session-telemetry` 和 `dsh-session-telemetry-otel`。 |
+| `session/user-id/`, `@deepseek-ai/dsh-user-id` | `session/anonymous-user-id/`, `@deepseek-ai/dsh-anonymous-user-id` | 该值是随机关联 id，并非经过身份验证的用户身份。 |
+| `USER_ID_FILE_NAME`、`.userid`，反馈标签 `User` | `ANONYMOUS_USER_ID_FILE_NAME`、`.anonymous-user-id`，反馈标签 `Anonymous user` | 文件和 UI 不得暗示账户身份。保留现有 `AnonymousUserId` 函数和标准 OTel 属性 `user.id`。 |
+| `util/environment/`, `@deepseek-ai/dsh-environment` | `util/launch-environment/`, `@deepseek-ai/dsh-launch-environment` | 该包在启动时捕获一份不可变的分层快照。它不是通用环境 API。 |
+| 公开的 `Environment*`、`createEnvironmentSnapshot`、`environmentOf`、`DSH_ENVIRONMENT_KEY` | `LaunchEnvironment*`、`createLaunchEnvironmentSnapshot`、`launchEnvironmentOf`、`DSH_LAUNCH_ENVIRONMENT_KEY` | 这些名称说明快照的生命周期和用途。 |
+| `ctx.launcherEnvironment` | `ctx.launchEnvironment` | 该值描述应用启动，而不只描述启动器组件。保留来源标签 `process`、`project-env` 和 `user-env`。 |
+
+### 工作流、目标与压缩
+
+| 当前名称 | 提议名称 | 理由 |
+|---|---|---|
+| `WorkflowService`, `ctx.workflows` | `WorkflowEngine`, `ctx.workflowEngine` | 一个引擎负责解析并执行工作流程序。复数键错误地暗示这是注册表。保留 `@deepseek-ai/dsh-workflow` 以及工作流事件和工具。 |
+| `@deepseek-ai/dsh-workflow-workerthread`, `WorkerWorkflowEngine` | `@deepseek-ai/dsh-workflow-worker-thread`, `WorkerThreadWorkflowEngine` | `worker thread` 是准确的 Node 机制，仓库拼写要求使用完整单词。 |
+| `@deepseek-ai/dsh-goal-session`, `goal/goal-session/` | `@deepseek-ai/dsh-goal-round-driver`, `goal/goal-round-driver/` | 该插件驱动同一会话内的 Goal Rounds。它既不存储目标，也不定义会话。保留 `GoalService`、目标来源、事件和约定。 |
+| `packages/compact/` | `packages/compaction/` | 该组是以名词命名的领域系列。`compact` 仍作为面向用户的命令动词。 |
+| `@deepseek-ai/dsh-compact`, `ctx.compact`, `CompactService` | `@deepseek-ai/dsh-compaction`, `ctx.compaction`, `CompactionEngine` | 该对象运行压缩（compaction）算法和生命周期。它是引擎，而不是通用服务。 |
+| `compact/*` 事件和公开领域前缀 | `compaction/*` | 事件和领域类型使用名词形式。保留动词形式的操作，例如 `compactNow`、`compactRegion` 和 `compactIfNeeded`。 |
+| `@deepseek-ai/dsh-compact-basic`、`BasicCompactService`、公开的 `BasicCompact*` | `@deepseek-ai/dsh-compaction-basic`、`BasicCompactionEngine`、对应的 `BasicCompaction*` | `basic` 朴素但准确。`compaction-llm` 没有增加信息，因为当前实现系列已使用 LLM。 |
+| `@deepseek-ai/dsh-compact-tool-result-prune`, `ToolResultPruneService`, `ctx.toolResultPrune` | `@deepseek-ai/dsh-compaction-tool-result-pruner`, `ToolResultPruner`, `ctx.toolResultPruner` | 该插件是剪除工具结果的执行主体。名词 `pruner` 说明了这一职责。 |
+
+保留 `/compact`、命令包，以及维持压缩定义包与提供方包分离的既有决策。本次重命名只改变词汇，不改变该包边界。
+
+### 设置、凭据、客户端模块和较小的核心职责
+
+| 当前名称 | 提议名称 | 理由 |
+|---|---|---|
+| 抽象类 `Settings` | `SettingsProvider` | 该类通过可替换能力提供设置。保留包、键和事件。 |
+| `@deepseek-ai/dsh-settings-local`, `SettingsLocal` | `@deepseek-ai/dsh-settings-file`, `FileSettingsProvider` | 该实现通过文件系统 seam 以文件为后端。`file` 说明机制，`local` 则不能。 |
+| 抽象类 `Credentials` | `CredentialProvider` | 该类解析凭据引用。保留包名、键和事件。 |
+| `CredentialsLocal` | `LocalCredentialProvider` | 该提供方读取宿主进程和 `.env` 状态，因此本地执行属于其约定。 |
+| `ClientModuleHostService`, `ctx.clientModuleHost` | `ClientModuleRegistry`, `ctx.clientModules` | 该服务拥有多个已注册的客户端模块。保留包和浏览器端的 `ClientModuleLoader`。 |
+| `AgentDefaultModelService` | `AgentDefaultModelConfig` | 该对象存储一项默认模型选择。它不运行服务，也不是通用注册表。保留其包、键、设置命名空间和类型。 |
+| `SessionReferenceService`, `ctx.sessionReferences` | `SessionReferenceResolver`, `ctx.sessionReferenceResolver` | 它从 URI 或输入解析一个会话引用，并不拥有引用集合。 |
+| `SessionQueryService`, `SessionQuerySqlite` | `SessionQueryEngine`, `SqliteSessionQueryEngine` | 这些类执行查询模型及其 SQLite 实现。保留包名、键和工具。 |
+| 宿主命令包中的 `CommandService` | `CommandRuntime` | 该对象跨实时调用注册并执行宿主命令。保留其包、键、类型和事件。 |
+| `TokenMeterService` | `TokenMeter` | 该对象测量 token 用量。`Service` 没有补充作用域信息。 |
+| `LlmService` | `LlmRuntime` | 该对象选择提供方并运行实时模型请求。保留包、键、适配器和事件。 |
+
+### Host Web 服务器、会话数据与代码执行
+
+| 当前名称 | 提议名称 | 理由 |
+|---|---|---|
+| `HttpServerService`, `ctx.httpServer` | `WebServer`, `ctx.webServer` | 该服务器拥有 HTTP 路由和 WebSocket 升级路由。`Web` 可以同时涵盖两者；此处的 `Http` 作用域过窄。保留 `packages/host/webserver`、`@deepseek-ai/dsh-host-webserver`、`WebRoute` 和 `WebUpgradeRoute`。 |
+| 文档子系统标签 `http-server` | `web-server` | 子系统标签必须与服务采用相同作用域。 |
+| `SessionPersistenceJsonl` | `JsonlSessionPersistence` | 将实现限定词放在前面，同时完整保留能力职责。 |
+| `SessionPersistenceSqlite` | `SqliteSessionPersistence` | 采用与 JSONL 相同的提供方命名顺序。 |
+| `@deepseek-ai/dsh-session-title-first-message-llm`，触发周期 `first-message` | `@deepseek-ai/dsh-session-title-first-prompt-llm`，触发周期 `first-prompt` | 触发条件是第一条用户提示词，而不是会话日志中的任意消息。 |
+| `@deepseek-ai/dsh-session-title-all-messages-llm`，触发周期 `all-user-messages` | `@deepseek-ai/dsh-session-title-all-prompts-llm`，触发周期 `all-prompts` | 后端根据用户提示词刷新。`all messages` 会错误地包含助手消息和工具事件。 |
+| `@deepseek-ai/dsh-code-runtime-worker`, `WorkerCodeRuntime` | `@deepseek-ai/dsh-code-runtime-worker-thread`, `WorkerThreadCodeRuntime` | 该实现使用 Node 工作线程。单独的 `worker` 作用域过宽。 |
+| `SubprocessService` | `SubprocessRuntime` | 该服务拥有实时子进程的执行和生命周期。保留其包和键。 |
+| `LocalSubprocessService` | `LocalSubprocessRuntime` | 该提供方运行同主机进程和进程树。 |
+| `E2BSubprocessService` | `E2BSubprocessRuntime` | 该提供方在 E2B 运行时中运行子进程。 |
+
+保留完整的会话投影系列和 `SessionProjection*` 词汇。投影是持续维护的读取模型；`Reducer` 只说明其折叠操作，会淡化缓存和查找职责。保留 `SessionTitleService`、检查点策略、持久化包名、时间上下文和 tmux 上下文。
+
+### 文件系统、skill、subagent 和 Web 提供方
+
+| 当前名称 | 提议名称 | 理由 |
+|---|---|---|
+| `@deepseek-ai/dsh-fs-policy` | `@deepseek-ai/dsh-fs-observation-policy` | 该包定义哪些文件系统观察可以授权后续操作。它不是完整的文件系统策略或沙箱策略。 |
+| `FsPolicyExec` | `FsObservationActor` | 该值表示策略所关联的观察与操作的执行主体。它本身不执行策略。 |
+| `SkillService` | `SkillRegistry` | 该服务注册提供方，并从其目录解析 skill（技能）。 |
+| `@deepseek-ai/dsh-skill-local`、`LocalSkillProvider`，提供方 id `local` | `@deepseek-ai/dsh-skill-filesystem`、`FileSystemSkillProvider`，提供方 id `filesystem` | 该提供方通过可位于本地或远端的 `ctx.fs` 发现 skill 文件。其机制是文件系统访问，而不是本地性。 |
+| `SubagentService` | `SubagentRuntime` | 该服务选择提供方，并拥有实时 spawn、恢复、跟进、取消和结算行为。 |
+| `@deepseek-ai/dsh-subagent-spawn`, `SpawnProvider` | `@deepseek-ai/dsh-subagent-spawn-in-process`, `SpawnInProcessProvider` | 该提供方在当前进程内启动子 agent。配置的提供方 id 仍为 `spawn`。 |
+| `@deepseek-ai/dsh-subagent-fork`, `ForkProvider` | `@deepseek-ai/dsh-subagent-fork-in-process`, `ForkInProcessProvider` | 该提供方在当前进程内 fork 一个 agent。配置的提供方 id 仍为 `fork`。 |
+| `@deepseek-ai/dsh-subagent-inprocess`, `subagent-inprocess/` | `@deepseek-ai/dsh-subagent-in-process-driver`, `subagent-in-process-driver/` | 该包包含通用的进程内驱动逻辑，而不是第三个提供方。 |
+| 私有的 `SdkProvider`，位于 `dsh-subagent-dsh-sdk` 中 | `SdkSubagentProvider` | 重复的包限定词是有意保留的，类名还必须说明它通过 SDK 提供 subagent。 |
+| `WebService`, `WebServiceConfig` | `WebRuntime`, `WebRuntimeConfig` | 该对象选择提供方并运行实时搜索和抓取操作。保留包、键、提供方包和模型工具。 |
+| `@deepseek-ai/dsh-web-fetch-local`、`LocalFetchProvider`、`LocalFetchLimits`，提供方 id `local-http` | `@deepseek-ai/dsh-web-fetch-http`、`HttpFetchProvider`、`HttpFetchLimits`，提供方 id `http` | 该提供方执行直接 HTTP 抓取。`local` 只说明代码恰好在哪里运行，并未说明它提供哪种机制。 |
+
+保留 `@deepseek-ai/dsh-subagent-dsh-sdk`、其提供方 id `dsh-sdk`、外部 ACP（Agent Client Protocol）、Codex 和 Claude Code 提供方系列、subagent 工具包名、主文件系统包和后端、文件系统工具和事件，以及 skill 徽章和工具包。
+
+### 钩子、防护、Plan Mode、扩展与诊断
+
+| 当前名称 | 提议名称 | 理由 |
+|---|---|---|
+| `@deepseek-ai/dsh-hooks-claude`、`ClaudeHookConfig`、`parseClaudeConfig`，方言 `claude` | `@deepseek-ai/dsh-hooks-claude-code`、`ClaudeCodeHookConfig`、`parseClaudeCodeConfig`，方言 `claude-code` | 该钩子桥接面向 Claude Code，而非所有 Anthropic 或 Claude 产品。 |
+| `@deepseek-ai/dsh-repeat-tool-guard`，插件／来源 `repeat-tool-guard` | `@deepseek-ai/dsh-repeat-tool-reminder`，插件／来源 `repeat-tool-reminder` | 该插件向模型添加提醒，并不阻止工具调用，也不执行防护决策。 |
+| `@deepseek-ai/dsh-timeout-policy` | `@deepseek-ai/dsh-tool-timeout-policy` | 该策略适用于工具执行。与早期尚未定案的 `timeout-guard` 目标相比，这一限定词更准确。 |
+| `PlanModeService` | `PlanModeController` | 该对象控制进入和退出计划模式的状态转换，而不是通用执行运行时。 |
+| `packages/self-modification/` | `packages/extensions/` | 该组包含仓库插件检查和挂载工具。`extensions` 说明稳定的包职责，但不声称 agent 会修改自身。保留包名 `tool-cordis` 和仓库插件名称。 |
+| `packages/support/` | `packages/test-support/` | 该组仅包含测试基础设施，其路径必须明确说明这一点。 |
+| `packages/support/invariants/` | `runtime-diagnostics/invariants/` | 尽管交付预设未包含不变量检查，它们仍可在生产诊断中运行，因此不属于测试支持。 |
+| `InvariantService` | `InvariantRegistry` | 该对象拥有已注册的不变量检查。保留 `@deepseek-ai/dsh-invariants` 和 `ctx.invariants`。 |
+| `packages/client/test-runtime/` | `packages/test-support/client-runtime/` | 该包是客户端测试基础设施。如果现有 NPM 名称已经说明这一约定，则予以保留。 |
+
+保留 MCP、Todo、Plan Mode 包、键、事件和工具名称。获准的变更针对控制器类，而不是产品功能。
+
+### 实用工具、E2B、Host、组合包、示例与应用
+
+| 当前名称 | 提议名称 | 理由 |
+|---|---|---|
+| `util/paths/`, `@deepseek-ai/dsh-paths` | `util/home-paths/`, `@deepseek-ai/dsh-home-paths` | 这些辅助函数解析 Harness 主目录下的路径，并非通用路径库。已准确说明返回路径的函数名保持不变。 |
+| `util/retention/`, `@deepseek-ai/dsh-retention` | `util/output-retention/`, `@deepseek-ai/dsh-output-retention` | 该策略保留命令和工具输出，而不是通用数据保留框架。 |
+| `E2BSandboxService` | `E2BRuntime` | 该类创建、复用和释放文件系统与子进程适配器所使用的 E2B 执行环境。它比单个沙箱句柄的职责更广，又比通用所有者更具体。保留 `@deepseek-ai/dsh-e2b`、`ctx.e2b` 和 `e2b/` 组。 |
+| `@deepseek-ai/dsh-frontend-static` | `@deepseek-ai/dsh-host-frontend-static` | 该包是提供前端资源的 Host 插件。此前缀可将它与前端应用代码区分开。 |
+| `@deepseek-ai/dsh-jsonrpc-demo` | `@deepseek-ai/dsh-sdk-jsonrpc-demo` | 该示例演示通过 JSON-RPC 使用运行时 SDK，属于 SDK 的唯一含义。 |
+| `@deepseek-ai/dsh-frontend` | `@deepseek-ai/dsh-web-frontend` | 该应用是 Web 前端。保留其物理目录 `apps/web/`。 |
+
+保留 atomic-write、brand、native-command、timeout 实用工具、目录选择器、`dsh-base`、`dsh-web-app`、应用启动、CLI（命令行界面）名称，以及 `headless` 包、组合包和示例身份。`headless` 是预期的产品本质，未来也可以支持不止一次性执行。
+
+### 客户端运行时与 UI
+
+| 当前名称 | 提议名称 | 理由 |
+|---|---|---|
+| `SlotsService` | `SlotRegistry` | 该对象拥有具名 slot 声明和注册项。 |
+| `SessionsService` | `SessionRuntime` | 该对象拥有实时客户端会话协调职责，而不是被动的会话列表。 |
+| `SessionHistoryService` | `SessionHistoryRegistry` | 该对象拥有已注册和已加载的历史记录条目。 |
+| `WorkspacesService` | `WorkspaceRuntime` | 该客户端对象协调实时工作区选择和操作。如果清单未点名更改某个现有 `ctx` 键，则该键保持不变。 |
+| `LocaleService` | `LocaleRuntime` | 该对象协调区域设置定义、选择、持久化和变更发布。 |
+| `ThemeService` | `ThemeRuntime` | 该对象协调主题、偏好解析、系统感知和变更发布。 |
+| `LayoutService` | `LayoutController` | 该对象控制当前 UI 布局状态。 |
+| `@deepseek-ai/dsh-client-ui-model` | `@deepseek-ai/dsh-client-ui-model-selection` | 该包控制会话的模型选择。单数 `model` 名称作用域过宽。 |
+| `ModelService`, `ctx.models` | `ModelDirectoryRegistry`, `ctx.modelDirectories` | 该服务注册多个模型目录。每个 `ModelDirectory` 仍是面向消费方的可选模型目录。 |
+| `@deepseek-ai/dsh-client-ui-models` | `@deepseek-ai/dsh-client-ui-settings-models` | 该包拥有 Models 设置面板。保留 `ModelsSettingsStore`；它保存一个具有数据操作和订阅能力的设置视图模型，确实是存储。 |
+| `@deepseek-ai/dsh-client-ui-plugin-config`、`client/ui-plugin-config/` | `@deepseek-ai/dsh-client-ui-settings-plugins`、`client/ui-settings-plugins/` | 该包拥有 Plugins 设置分区，而不是通用的插件配置系统。目标名称归入 `ui-settings-*` 系列，并采用该分区的复数产品名。 |
+| `PluginConfigSection`、`PluginConfigSectionProps`、`PluginConfigSectionInjected`、`settings.pluginConfig` | `PluginsSettingsSection`、`PluginsSettingsSectionProps`、`PluginsSettingsSectionInjected`、`settings.plugins` | 这些名称描述 Plugins 设置呈现。每张卡片仍编辑一个插件的配置，但该分区本身是设置 UI。 |
+| `agent-loop-store.ts`、`bash-store.ts`、`web-search-store.ts` | `agent-loop-card-controller.ts`、`bash-card-controller.ts`、`web-search-card-controller.ts` | 每个模块都导出一个卡片控制器。私有 `SnapshotStore` 字段不会让模块成为存储。 |
+| `card-store.ts` | `card-form.ts` | 该模块拥有暂存表单、字段转换和表单操作。它返回的快照存储是呈现适配器，而不是模块的主要职责。 |
+| `@deepseek-ai/dsh-client-ui-question` | `@deepseek-ai/dsh-client-ui-user-questions` | UI 呈现用户问题 seam，而不是任意问题领域。 |
+| `@deepseek-ai/dsh-client-ui-command`, `ui-command/` | `@deepseek-ai/dsh-client-ui-commands`, `ui-commands/` | 该包呈现并运行一组命令。 |
+| 客户端 `ctx.command`、`CommandService`、`CommandServiceContract` | `ctx.commandUi`、`CommandUiRuntime`、`CommandUiContract` | Host 已拥有 `ctx.commands`。该客户端服务是命令发现和执行的 UI 运行时。现有 `CommandUiSpec` 确立了 `Ui` 大小写格式。 |
+| `ConversationService` | `ConversationController` | 该对象控制当前对话状态和用户操作。 |
+| `InputService` | `SessionInputResolver` | 该接口为一个会话作用域解析输入外观。它既不是全局输入注册表，也不是执行服务。保留 `InputHub` 作为具体中枢，并保留 `ctx.conversation.input` 作为对外接口。 |
+
+PascalCase 标识符内部使用 `Ui`，不要使用 `UI`。除非清单明确要求重命名，否则保留其余客户端包名。暂时保留已弃用的客户端连接和 Host `ApiProxy` 词汇；API 平面将替换它们，而在计划移除的表面上重命名只会增加改动量。
+
+## 明确保留的名称
+
+以下经过讨论的名称保持不变，因为当前作用域准确，或重命名会制造虚假概念：
+
+- 保留完整的 sandbox 系列和 `ctx.sandbox`。不得引入 `processSandbox`。
+- 保留 `@deepseek-ai/dsh-api-gateway`、`ctx.typertGateway` 和 `TypertGatewayService`。
+- 保留会话投影名称。投影并不只是归约函数。
+- 保留 `GoalService`；它拥有目标状态机、裁决权、比较并设置行为、事件和远程操作，不只是存储。
+- 保留 `SessionTitleService`；它的职责是由多个标题提供方共享的领域服务。
+- 保留 `PermissionPresetSettingsController`，即使它很长。每个词都在限定其职责。
+- 保留 `ModelsSettingsStore`；其主要约定是一个具有存储操作的设置数据模型。
+- 保留 `InputHub`；它是支撑 `SessionInputResolver` 的具体中枢。
+- 保留 `dsh-subagent-dsh-sdk` 和提供方 id `dsh-sdk`；重复的限定词可避免歧义。
+- 保留 `headless`；即使运行时以后支持不止一次性使用，该产品身份仍然准确。
+- 保留已弃用的 Host `ApiProxy` 和客户端连接名称，直至 API 替代方案将其移除。
+- Host 服务器和提供方无关的 Web 能力都保留 `Web`。仅直接抓取提供方使用 `HTTP`。
+- 保留 `E2B` 作为包名和上下文名称，不改为 `E2B sandbox`。
+- 保留 MCP、Todo、目录选择器、应用启动、基础组合包、web-app 组合包和 CLI 名称。
+
+## 考虑过的替代方案
+
+**保留现有名称并添加词汇表。**不予采纳。词汇表无法让由 PowerShell 实现的 `BashExecutor` 名副其实，也无法让 `ToolRegistry` 表明它会执行并强制实施工具策略。标识符本身必须承载有用的区别。
+
+**为每个 NPM 包添加所属组前缀。**不予采纳。扁平的 NPM 名称不需要复刻目录树。机械添加前缀只会增加长度，无法解释包的职责。
+
+**将整个仓库称为 SDK。**不予采纳。该项目是 agent harness（智能体框架）。SDK 是 Python 和 TypeScript 客户端使用的、受支持的 JSON-RPC 客户端／服务器栈。一词两义会使包名和产品文案产生歧义。
+
+**所有 Cordis 服务类都使用 `Service`。**不予采纳。Cordis 继承只是实现事实。类名必须告诉调用方该对象负责注册、存储、解析、控制还是运行工作。
+
+**统一使用 `Runtime` 替换 `Service`。**不予采纳。只有对象拥有实时执行或生命周期时，`Runtime` 才正确。注册表、存储、目录、控制器、解析器、引擎和配置对象都应保留更精确的职责名。
+
+**优先使用最短的名称。**不予采纳。只有作用域明确之后，简短才有价值。`PermissionPresetSettingsController` 保留 `Preset`；`JobId` 简短，是因为 `Job` 已经表明领域；`BgTaskId` 虽短，却晦涩难懂。
+
+**为未来可能出现的功能使用宽泛名称。**不予采纳。应按稳定的当前职责命名。未来若要改变边界，可以在发布前再次重命名对象，或在发布后另写提案。含义模糊的名称会让每位当前读者为尚未构建的未来付出理解成本。
+
+**将 `dsh-compact-basic` 重命名为 `dsh-compaction-llm`。**不予采纳。`LLM` 没有在当前后端系列中增加区别。`basic` 意图更克制，也不会声称存在一个实际并不存在的算法。
+
+**将会话投影重命名为归约器。**不予采纳。归约只是构建投影的方式。该包还拥有读取模型值、缓存和查找约定。
+
+**将持久 Bash 工具重命名为 `bash-terminal`。**不予采纳。该名称与终端会话系列冲突。将 `tool-bash-persistent` 移到 `shell/` 可以纠正其归属位置，同时现有名称仍能将其与一次性 Bash 工具区分开。
+
+**应用清单时一并重命名或拆分边界。**不予采纳。评审人必须能够确认行为没有改变。真正的边界缺陷需要独立提案、测试和后果分析。
+
+**为旧名称保留别名。**不予采纳。没有已发布的消费方需要这些别名。别名会保留两套词汇，使首次发布携带一项从未有用户需要的迁移。
+
+## 验收标准
+
+- 应用清单中的每项映射；如果决策发生变化，则必须在实施前修订本提案并说明原因。
+- 每个系列只有一套公开词汇。不得留下兼容包、重新导出别名、重复的 `ctx` 键、双重插件 id、双重事件 id、旧工具别名或回退解析器。
+- 变更只能重命名。运行时行为、包边界、默认值、策略、持久化语义和模型行为必须保持等价，只有标识符本身可见时除外。
+- 包目录、NPM 名称、导入、manifest（元数据清单）、TypeScript 引用和路径、Cordis 配置、插件 id、服务键、事件、工具、RPC 名称、清单点名的持久化名称、fixture、快照、示例、生成的目录和当前文案都采用新词汇。
+- 实现合入时，以事实性名称和路径变更更新当前处于 implemented 状态的 Agent Note。包重新分组说明应记录 `dsh-sdk-jsonrpc-server`，且不再将仓库称为 SDK。架构决策仍然有效的说明，不得被重写为新的决策。
+- 配对的包创建指南应包含职责词约定，`packages/AGENTS.md` 应链接到该约定，术语表应记录选定用词和 `Typert` 拼写，根项目文案应将产品称为 DeepSeek Harness，而不是 DeepSeek Harness SDK。
+- 已移除的 SDK 项目工具链继续保持不存在。
+- 聚焦测试覆盖每个重命名系列；在完整实现上，源代码平面的类型检查、构建、包卫生检查、生成参考资料门禁、受可见标识符影响的快照、翻译配对、`doc-sync` 和 lint 均应通过。
+- 只有完整清单和文档约定全部成为事实后，才能将该 proposed 说明移入 `implemented/`。其实现版应描述最终状态，而不是迁移检查清单。
+
+## 风险
+
+这轮整体重命名会更改大量导入、路径、配置字符串、生成的参考资料和模型可见名称。遗漏的字符串可能通过编译，却在加载或回放时失败。实现时必须结合类型驱动的修改，并在源代码、配置、测试、fixture、文档和生成输入中精确搜索旧名称。
+
+并行工作会与路径移动和符号重命名产生冲突。这是发布前的临时成本。按职责一致的系列拆分实现，可以降低评审成本和合并冲突，但每个系列都必须保持原子性。
+
+一些名称会变得更长。额外增加的词只有在防止误述权限或机制时才有意义。如果名称中的词不能全部限定职责，长名称仍然是失败的命名。
+
+如果评审人只检查后缀而不检查行为，职责词汇就会沦为机械套用。指南必须保留本说明中的直接判断方式：检查调用方执行什么操作、对象拥有什么生命周期，以及对象控制什么失败或策略。
+
+清单点名的旧磁盘名称、协议值、工具名称和配置项将停止工作。发布前接受这一后果。如果负责解析的解析器能够识别陈旧配置，实现必须明确报错；不得静默接受两种形式。
