Knowledge base data plane for dsh-trading: KnowledgeCard data model, validation, graph builder, atomic file store, and knowledge_ingest / knowledge_search agent tools.

Market routing for dsh-trading: user settings namespace dshtrading (markets.<market>.provider) + tradingMarketRouter service consulted by connectors at apply time

Trading strategies kernel for dsh-trading: pure math backtesting engine, strategy contracts, and 6 reference paradigms (short, swing, long). Pure library (zero runtime dependencies, browser-packable).

US market bundle for dsh-trading: host-plane us-trader preset installer + insert-only aggregation of the yahoo connector and us kit rows (design rule #1)

Host-side watchlist + selection stores for dsh-trading: multi-list file store (~/.dsh/watchlists.json), selection store (~/.dsh/selection.json), and cross-market watchlist_* tools (watchlist_list/add/remove/select) on the host plane

Automation-only Agent Client Protocol server for driving DeepSeek Harness agents over JSON-RPC stdio

Typert Remote Host dispatcher and Client API endpoint

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)

Schema/draft model layer for settings editors: rehydrates a serialized schemastery schema, validates drafts, and edits them immutably by path

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

Pure React attachment atoms for the dsh web UI: draft-image rail, message image gallery, and original-image lightbox (zero cordis)

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

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