DeepSeek Harness プラグイン — 33 ページ

Remote BFF assembly and Host Agent/Session lookup policy

Shared boot glue for the app bins: .env loading, fail-loud Loader guards, snapshot-aware config resolution, and the Loader boot sequence

Durable immutable attachment storage seam for the DeepSeek Harness

Private content-addressed DSH_HOME attachment storage

The shared dsh core as a profile bundle: every profile's first patch layer, inserting the base plugin rows over the empty profile root

Wire consumer layer: HTTP-up/WebSocket-down client, ConnectionController dual streams with reconnect, and fixture api

Dev-only hot-reload driver for script-loaded client entries: SSE rebuilt frames → invalidate/prefetch → fiber swap through the vendored Loader entry

Locale plugin: Host-backed zh/en preference, browser-derived fallback, locale snapshots, and typed namespace dictionaries

Client module system, dual-face: node half composes the __DSH_BOOT__ entry graph (incremental dsh.client scan, bundle route, index tap, webPlugins service); browser half is the lazy-CJS module table the vendored cordis Loader consumes as its internal seam

Client core services: SlotRegistry, SessionRuntime (scope tree + object layer)

Agent-preset surfaces: the default for later sessions, this session's seat, and the composition editor

Dynamic attachment presentation plugin for conversation input and message-image slots

Official DeepSeek Harness brand occupants for the Web client's sidebar and conversation Hero slots

Client command surface: global directory cache, '/' source, three command UI kinds, popupSelect registry

Conversation domain: skeleton, ordered chat flow, composer with the Host-backed busy-Enter preference, and details host

Produced-files turn tail and clickable final-response file references for Web

DSH Design Mode infinite image canvas, inline comments, version tree, and composer context sync

In-app directory browsing surface: the workspace directory-flow owner rendering the host's listing and creation primitives

Native directory-picker surface: the renderless workspace directory-flow occupant driving the host's OS chooser

Session goal surface: GoalBar docked above the composer, read from the goal session projection

Input trigger pipeline: '/' and '@' detection, candidate menu, pick routing to registered sources

Session-header background-job list: live registry state mirrored from session/jobs frames

Shell plugin: three-column AppFrame with drag handles, ctx.layout viewing-state service (navigation + panels)

Per-message feedback controls contributed to the assistant-message action strip, backed by the messageFeedback Host Remote
