Summary

  • add private JCode-managed no-project workspaces under ~/.jcode/workspace/YYYY-MM-DD-NNN
  • persist workspace_kind across session metadata, activation, status APIs, engine state, and frontend state
  • expose Work without a project in the product composer and merge scratch conversations into one No project sidebar group
  • keep scratch tasks isolated from project config, project skills, project workflows, and project-memory writers
  • preserve stable activity sorting and reject managed scratch paths from project-classified sessions

Model review

  • reviewed independently with Grok and Kimi in read-only Plan sessions
  • fixed scratch inheritance for empty Cloud/session activation
  • fixed composer project-path synchronization after same-workspace new sessions
  • fixed background scratch activity classification in the Redux project-kind map

Validation

  • go test ./...
  • make lint
  • Web Vitest: 163 tests passed
  • jcode-ui Vitest: 47 tests passed
  • make build-web
  • go build ./cmd/jcode
  • local browser E2E verified menu ordering, selected state, unique 001/002 allocation, scratch status response, and no console errors
  • repository pre-push checks passed

Summary by CodeRabbit

  • New Features
    • Added “Work without a project” scratch workspaces for starting tasks independently of a project.
    • Scratch workspaces receive managed, isolated directories and are restored across sessions.
    • Sidebar, workspace picker, task details, command palette, and chat views distinguish project and scratch tasks.
    • Added sorting, grouping, labels, icons, and status indicators for scratch workspaces.
  • Improvements
    • Workspace type is preserved when switching, reopening, or creating conversations.
    • Added localized scratch-workspace text in English, Japanese, Korean, and Chinese.

📝 Walkthrough

Walkthrough

This change adds project and scratch workspace classification across session persistence, backend engine construction, managed directory allocation, activation APIs, frontend state, workspace navigation, task grouping, and localized presentation.

Changes

Scratch workspace support

Layer / File(s) Summary
Workspace classification and persistence
internal/session/..., internal/workspace/...
Adds project and scratch workspace kinds, normalizes legacy values, persists classifications, updates project metadata, and allocates validated managed scratch directories.
Scratch engine and activation flow
internal/command/web.go, internal/web/...
Adds scratch-specific engine construction, skips project-only configuration and tools, manages scratch activation and cleanup, validates workspace transitions, and reports workspace kinds through server APIs.
Workspace state and session API flow
web/src/app/..., web/src/lib/..., web/src/App.tsx, web/src/components/AuthGate.tsx, web/src/components/SetupView.tsx, web/src/components/RemoteConnectWizard.tsx
Carries workspace classification through API types, session state, conversation restoration, new-session provisioning, retries, setup, authentication, and remote binding.
Workspace picker and sidebar behavior
packages/jcode-ui/src/product/..., web/src/components/Sidebar.tsx, web/src/components/Sidebar.scratch.test.tsx
Separates scratch tasks from project tasks, adds scratch creation controls, sorts workspace activity, and renders dedicated scratch groups and labels.
Scratch workspace presentation
web/src/components/ChatView.tsx, web/src/components/CommandPalette.tsx, web/src/components/DesktopTitlebar.tsx, web/src/i18n/locales/*
Displays no-project labels, scratch task hints, title-bar badges, welcome text, sidebar actions, and translations for supported locales.

Exclude project agent roles from scratch tasks. config.LoadAgentRoles(taskPwd) reads taskPwd/.jcode/agents and passes those roles to subagent and workflow tools. Other role paths also use taskPwd, including optionalCustomAgentRole, resolveWebCustomAgentSelection, and context breakdown. When scratch is true, load only user-scoped roles or skip role selection in all these paths. Otherwise project role instructions and model overrides bypass scratch isolation.

Reject managed scratch paths for persisted project sessions.

Line 307 skips this validation when meta != nil. A legacy or persisted session with project classification and a managed scratch path can then resume with newEngine instead of newScratchEngine. This bypasses scratch isolation.

Apply the managed-path rejection whenever workspaceKind == session.WorkspaceProject.

Proposed fix
-	if meta == nil && workspaceKind == session.WorkspaceProject && project != "" {
+	if workspaceKind == session.WorkspaceProject && project != "" {
 		if err := managedworkspace.ValidateScratchPath(project); err == nil {
 			return activationResult{}, fmt.Errorf("%w: managed scratch workspace cannot be opened as a project", errInvalidConversationTarget)
 		}
 	}

The PR objective requires managed scratch paths to be rejected from project-classified sessions.

Isolate scratch workspace tests from the user home directory.

Both tests allocate through config.ConfigDir() via CreateScratch, but neither test sets HOME. They can create ~/.jcode/workspace entries in the real user home.

Set HOME to t.TempDir() before stubFactoryServer(t) in both tests.

Proposed fix
 func TestNewScratchSessionAllocatesManagedWorkspace(t *testing.T) {

 	s := stubFactoryServer(t)

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Propagate cancellation through scratch workspace operations.

CreateScratch and ValidateScratchPath perform filesystem operations without context.Context. Activation calls both while it holds taskCreateMu. A canceled request can continue this work and delay other activations.

Add context.Context as the first parameter to both functions. Check ctx.Err() before work and during the allocation retry loop. Pass the handler context from ensureConversationLocked.

As per coding guidelines, “Use context.Context as the first parameter and propagate cancellation correctly.”

Summary

The PR adds JCode-managed "no-project" (scratch) workspaces end to end; the Go side builds cleanly and the full go test ./... suite (including the new scratch tests) passes. Backend allocation, validation, session-index persistence, and resume flows check out against the traced callers. One verified defect: the workspace picker's new recency-based ordering compares RFC3339 timestamps lexically, which mis-sorts workspaces when offsets mix — the exact hazard the codebase's own Sidebar code guards against with parsed-instant comparison. Frontend typecheck/vitest could not run in this environment (no pnpm/node_modules).

P3 · Workspace picker sorts/merges workspace recency with RFC3339 string comparison, mis-ordering mixed-offset timestamps

The new recency ordering compares timestamps as raw strings: the merge if ((task.updated_at || '') &gt; existing.updatedAt) and the sort b.updatedAt.localeCompare(a.updatedAt). But task updated_at values mix formats: the backend writes time.Now().Format(time.RFC3339) with a local offset (e.g. "2026-08-19T10:00:00+08:00") while optimistic sidebar upserts (revealSessionInSidebar) write new Date().toISOString() (UTC "Z"). Sidebar.tsx already built tsCmp specifically because "RFC3339 string order breaks across UTC offsets (the index mixes server-local \"+08:00\" writes with UTC \"Z\")". Concretely, "2026-08-19T10:00:00+08:00" sorts as newer than "2026-08-19T05:00:00Z" lexically although it is 02:00Z (older), so the picker shows workspaces in the wrong recency order once any mixed-offset data is present.

Suggested change
const byActivity = b.updatedAt.localeCompare(a.updatedAt)
if (byActivity !== 0) return byActivity
Compare parsed instants instead of strings, e.g. reuse the tsCmp-style comparison from web/src/components/Sidebar.tsx: merge with `Date.parse(a) > Date.parse(b)` and sort with a comparator over Date.parse(updatedAt) (treat NaN as oldest), for both the existing.updatedAt merge (line 66) and the sort (line 83).
