A React helper hook for scheduling a layout effect with a fallback to a regular effect for environments where layout effects should not be used (such as server-side rendering).

Local-filesystem implementation of the DeepSeek Harness spill storage seam (private session-scoped files)

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

Theme plugin: ThemeService (light/dark/system preference, prefers-color-scheme resolution, theme/change snapshots; no DOM), --dsw-* token base stylesheets; registers the Appearance settings row

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

Adaptive chooser of the directory-picker seam: resolves the host situation at boot and mounts the native or browse backend for the DeepSeek Harness web GUI host

Agent-plane presentation selector: composes one agent's tools as Code Mode, native, or both

Shared anonymous user identity for DeepSeek Harness telemetry and feedback correlation

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

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

User-facing permission presets (ctx.permissionPresets) for the DeepSeek Harness: one product-level Permissions select bundling the sandbox-mode and approval-policy knobs, written through to their own session events

In-process fork subagent backend: runs a child agent seeded with a prefix of the parent's log

Settings ownerless-copy and product onboarding plugin: the General section, shell trigger/header chrome content, settings dictionaries, and the versioned welcome notice

Web route-registration plugin: HTTP and upgrade routes, index transform taps, and static dist fallback; knows no harness concepts

Semantic session durability checkpoints before model requests and tool side effects

Session Controller adapter for React and session-scoped slots

Approval composer takeover over the scoped Remote Event waterfall

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

Permission surfaces: a new-session default in General settings and a current-session /permission popup over the permissions projection

Durable workflow-run Conversation Node and nested member disclosure for dsh web
