feat: workspace backend foundation (PR-1)

- Add workspaces table migration (2026_06_01_add_workspaces)
- Create Workspace model with repo_id, user_id, branch, path, status
- Add workspace_id nullable FK to ToolInstance
- Create GitService for clone/fetch/pull/branch_exists_remotely
- Create WorkspaceManager for create/delete/sync lifecycle
- Create workspace CRUD API with 409 handling for duplicates and instances
- Wire workspace routes into FastAPI app
- 17 tests passing (8 unit + 9 integration), 1 skipped

Quality gates: ruff clean

# Design: Workspace-Based Tool Instances
## Status
| Field | Value |
|---|---|
| Phase | **Design** |
| Based on | [Spec](spec.md) |
| Next | Tasks |
## Decision: No Migration
Existing tool instances will be left as-is. Users will create new workspaces and new tool instances. Old instances remain functional but read-only (no migration path). This simplifies the implementation significantly.
## Architecture Overview

### Component: WorkspaceCard
```tsx
export function WorkspaceCard({
workspace,
onStartTool,
onSync,
onDelete,
}: WorkspaceCardProps) {
return (
<article className="card workspace-card">
<div className="workspace-header">
<h4>{workspace.name}</h4>
<span className={`status-badge ${workspace.status}`}>

<Icon name="refresh" /> Sync
</button>
<button onClick={() => onDelete(workspace)} className="danger">
<Icon name="delete" /> Delete
</button>
</div>
</article>
);
}
```
### Component: Sidebar (updated)
```tsx
const navItems = [
{ path: "/dashboard", label: "Dashboard", icon: "home" },
{ path: "/projects", label: "Projects", icon: "folder" },
{ path: "/workspaces", label: "Workspaces", icon: "workspace" },
{ path: "/settings", label: "Settings", icon: "settings" },
];
```
### Hook: useWorkspaceActions
```typescript
export function useWorkspaceActions(options: { onRefresh: () => Promise<void> }) {
const [loadingId, setLoadingId] = useState<string | null>(null);
const handleDelete = useCallback(async (workspace: Workspace, force = false) => {
setLoadingId(workspace.id);
try {
await deleteWorkspace(workspace.repo_id, workspace.id, force);
await options.onRefresh();
} catch (err) {
const error = err as AxiosError<{ detail?: { instances?: Array<{id: string, name: string}> } }>;
if (error.response?.status === 409 && !force) {
const instances = error.response.data?.detail?.instances || [];
const confirmed = confirm(
`This workspace has ${instances.length} running tool instance(s):\n` +
instances.map(i => `- ${i.name}`).join("\n") +
`\n\nDelete workspace and all instances?`
);
if (confirmed) {
await handleDelete(workspace, true);
}
}
} finally {
setLoadingId(null);
}
}, [options.onRefresh]);
const handleSync = useCallback(async (workspace: Workspace) => {
setLoadingId(workspace.id);
try {
const result = await syncWorkspace(workspace.repo_id, workspace.id);
await options.onRefresh();
return result;
} catch (err) {
const error = err as AxiosError<{ detail?: { branch_deleted?: boolean; message?: string } }>;
if (error.response?.status === 409 && error.response.data?.detail?.branch_deleted) {
const confirmed = confirm(
`${error.response.data.detail.message}\n\nDelete this workspace?`
);
if (confirmed) {
await handleDelete(workspace, true);
}
}
} finally {
setLoadingId(null);
}
}, [options.onRefresh, handleDelete]);
return { loadingId, handleDelete, handleSync };
}
```
## Compose Template Updates
### Workspace Mount
All compose templates will mount the workspace path instead of the repo path:
```yaml
services:
app:
image: ${IMAGE_TAG}
container_name: ${INSTANCE_NAME}
volumes:
- ${WORKSPACE_PATH}:/workspace
working_dir: /workspace
# ... rest of config
```
The `${WORKSPACE_PATH}` variable replaces `${REPO_PATH}` in all templates.
## Error Handling
| Error | HTTP Status | Frontend Behavior |
|---|---|---|
| Workspace name not unique per repo | 409 | Show inline validation error |
| Workspace has running instances | 409 | Show confirmation dialog |
| Branch deleted from remote | 409 | Show confirmation dialog to delete workspace |
| Repo not found | 404 | Show error toast |
| Git clone failed | 500 | Show error toast with git stderr |
| Workspace path missing | 500 | Show error toast |
## Performance Considerations
- **Git clone** is synchronous and slow; run in background with status polling
- **Workspace list** should include `instance_count` via subquery (not N+1)
- **Sync** is fast (fetch only), but pull may be slow; run async
- **Delete with instances** stops instances sequentially; consider parallel
## Security Considerations
- Workspace paths must be validated to prevent path traversal
- Users can only access their own workspaces
- Git credentials (SSH keys) must be available during clone
- Workspace directories must have correct ownership for container users
## Testing Strategy
### Backend
- Unit: WorkspaceManager.create, delete, sync
- Unit: GitService.clone, fetch, pull, branch_exists_remotely
- Integration: Create workspace → start tool → verify mount
- Integration: Delete workspace with running instances
- Integration: Sync with deleted branch
### Frontend
- Component: WorkspaceCard renders correctly
- Component: Create form validates name uniqueness
- Hook: useWorkspaceActions handles 409 confirmation
- E2E: Create workspace → start tool → delete workspace
## Out of Scope
- Auto-sync on schedule
- Workspace sharing between users
- Git push/pull/branch UI
- Pre-created default workspaces
- Read-only workspace mode
- Workspace backup/restore

# Explore: Working Copies
## Problem Statement
Currently, tool instances mount repositories directly. Each tool instance either:
- **Mount mode**: Bind-mounts the shared repo path (`/data/repos/<repo>`) read-only
- **Clone mode**: Clones the repo into the instance directory
This has several problems:
1. **Mount mode**: Read-only, so users can't edit files in the tool
2. **Clone mode**: Creates a full copy per instance, wasting disk space
3. **UI complexity**: The create-instance form must ask "mount or clone?" and handle branch selection
4. **No persistence**: Clone-mode repos live inside the instance directory and are lost on delete
5. **Race conditions**: Multiple instances mounting the same repo can conflict
## Proposed Solution: Working Copies
Introduce a **Workspace** as a first-class entity: a persistent, writable local clone of a repository that lives independently of any tool instance. Tool instances are then *started on* a working copy, which is mounted into the container.
### Naming Candidates
| Name | Pros | Cons |
|---|---|---|
| Workspace | Common in IDEs; implies a working area | Conflicts with existing docs/features/workspace.md |
| **Workspace** | Common in IDEs (VS Code, JetBrains); implies a working area | May conflict with existing "workspace" terminology in docs |
| **Checkout** | Git-native term; implies a working tree | Too specific to git; implies a single commit/branch |
| **Sandbox** | Implies isolation and experimentation | Suggests throwaway/ephemeral, not persistent |
| **Dev Copy** | Simple and descriptive | Informal; "copy" still implies duplication |
| **Project Clone** | Clear relationship to project+repo | Clunky; two words |
| **Branch** | Git-native; each working copy is effectively a branch workspace | Too git-specific; may confuse with git branches |
**Decision: "Workspace"** — chosen by user despite existing docs/features/workspace.md. The existing workspace.md will be superseded/renamed to avoid confusion. — it's the most precise term. In SVN/Git parlance, a "working copy" is exactly what we want: a local, writable copy of a repository that you work on. The term is established enough that developers understand it, but not so overloaded in our domain that it conflicts.
### Entity Model
```
Project
└── GitRepository (the canonical repo, read-only source)
└── WorkingCopy (writable local clone, 1+ per repo)
└── ToolInstance (mounts the working copy)
```
A Workspace:
- Has a `name` (auto-generated or user-defined)
- Has a `path` on disk (under `/data/working-copies/<repo-id>/<copy-name>`)
- Has a `branch` (the branch it's currently on)
- Has a `status` (ready, syncing, error)
- Belongs to a `GitRepository`
- Belongs to a `User`
- Has many `ToolInstance`s
### User Flow
1. User navigates to **Working Copies** in the sidebar
2. Sees list of working copies (or creates one from a repo)
3. Clicks "New Workspace" → selects repo + branch → named copy created
4. From a working copy, clicks "Start Tool" → selects tool type → instance starts with working copy mounted
5. Multiple tool instances can share the same working copy (e.g., terminal + code-server side by side)
### Benefits
1. **Writable by default**: Working copies are clones, so tools can edit files
2. **Shared across instances**: Multiple tools can mount the same working copy
3. **Persistent**: Survives instance deletion
4. **Simplified UI**: No more "mount vs clone" decision; tool creation is just "pick a working copy"
5. **Git operations**: Working copies can support git push/pull/branch from the UI
6. **Disk efficient**: One clone per working copy, not one per instance
### Open Questions
1. Should working copies auto-sync with the canonical repo?
2. Should we support multiple working copies per repo (e.g., one per branch)?
3. How do we handle merge conflicts if the canonical repo changes?
4. Should working copies be scoped to a user or to a project?
5. What happens to tool instances when a working copy is deleted?
6. Should we pre-create a default working copy when a repo is added?
### Migration Path
Existing tool instances that use clone_mode can be migrated:
- On first access, extract the cloned repo from the instance directory
- Move it to `/data/working-copies/...`
- Create a WorkingCopy record pointing to it
- Update the instance to mount the working copy path
Mount-mode instances can be converted on restart:
- Create a working copy from the canonical repo
- Switch the instance to mount the working copy instead
### Scope for This Change
This change focuses on:
- [ ] Creating the WorkingCopy entity and database table
- [ ] Adding a Working Copies section to the UI (sidebar nav + list view)
- [ ] Updating tool instance creation to select a working copy instead of repo+clone_mode
- [ ] Updating compose generation to mount the working copy path
- [ ] Migrating existing clone_mode instances to use working copies
Out of scope (future changes):
- [ ] Auto-sync with canonical repo
- [ ] Git operations UI (push/pull/branch)
- [ ] Working copy sharing between users
- [ ] Pre-create default working copies

# Proposal: Workspace-Based Tool Instances
## Status
| Field | Value |
|---|---|
| Phase | **Proposal** |
| Based on | [Explore](explore.md) |
| Next | Spec |
## Decisions from Explore
| Decision | Value |
|---|---|
| **Name** | "Workspace" (supersedes existing workspace.md) |
| **Scope** | Unlimited workspaces per repository |
| **Auto-create** | No — explicit creation only |
| **Default branch** | Main/master or user-selected at creation time |
| **Delete with running instances** | Allowed with confirmation; stops and deletes all associated tool instances |
| **Name uniqueness** | Unique per project+repo (derived from project and repo names) |
| **Deleted remote branch** | On sync/update, detect and ask for confirmation to delete local workspace/branch |
## Problem Statement
The current tool instance creation requires users to choose between "mount" (read-only) and "clone" (writable but ephemeral) modes. This is confusing and leads to either:
- **Mount mode**: Tools open files read-only, frustrating editing
- **Clone mode**: Each instance clones the repo, wasting disk space and losing work on deletion
## Proposed Solution
Introduce **Workspaces** as first-class entities: persistent, writable local clones of a repository that exist independently of tool instances. Users create workspaces explicitly, then start tool instances *on* a workspace.
### Entity Relationship
```
Project
└── GitRepository (canonical source)
└── Workspace (writable clone, unlimited per repo)
└── ToolInstance (mounts workspace path)
```
### Key Behaviors
1. **Workspace Creation**: User selects a repository → picks a branch → names the workspace → clone is created on disk
2. **Tool Instance Creation**: User selects a workspace → picks a tool type → instance starts with workspace mounted
3. **Multiple Tools per Workspace**: Several tool instances can share the same workspace (e.g., terminal + code-server)
4. **Persistence**: Workspaces survive tool instance deletion
5. **No Auto-Create**: Users must explicitly create workspaces; no magic default workspace
### UI Changes
- **New sidebar entry**: "Workspaces" (between "Projects" and "Settings")
- **Workspaces page**: List of all workspaces with repo/branch/status info
- **Create workspace flow**: Repo picker → branch picker → name input
- **Start tool from workspace**: Tool picker modal from workspace card
- **Simplified tool creation**: Remove "clone mode" / "mount mode" toggle; always use workspace
### Database Changes
New table: `workspaces`
- `id` (UUID, PK)
- `name` (string, user-defined)
- `repo_id` (UUID, FK → git_repositories)
- `user_id` (UUID, FK → users)
- `branch` (string)
- `path` (string, absolute disk path)
- `status` (enum: ready, syncing, error)
- `created_at`, `updated_at`
Updated: `tool_instances`
- Add `workspace_id` (UUID, FK → workspaces, nullable for migration)
- Remove `clone_mode` (deprecated)
- Remove `branch` (moved to workspace)
### File System Layout
```
/data/working-copies/
└── {repo-id}/
└── {workspace-name}/
└── .git/
└── [repo files]
```
### Migration Strategy
Existing `clone_mode` instances:
- Extract cloned repo from instance directory
- Move to `/data/working-copies/{repo-id}/{instance-name}/`
- Create Workspace record
- Update instance to reference workspace
- Remove `clone_mode` flag
Existing `mount_mode` instances:
- On next start, create a workspace from the canonical repo
- Switch instance to use workspace
- Remove `clone_mode` flag
### Out of Scope
- Auto-sync with canonical repo
- Git push/pull/branch UI
- Workspace sharing between users
- Pre-created default workspaces
- Read-only workspace mode
## Risks
| Risk | Mitigation |
|---|---|
| Existing users with many clone_mode instances | One-time migration on instance restart |
| Disk space from many workspaces | User-managed; can delete workspaces |
| Workspace deleted while instances are running | Allowed with confirmation; cascade-delete tool instances |
| Name collisions for workspace names | Unique per project+repo; derived from project and repo names |
## Acceptance Criteria
- [ ] User can create a workspace from any repository
- [ ] User can create unlimited workspaces per repository
- [ ] Tool instances mount the workspace path, not the canonical repo path
- [ ] Multiple tool instances can share one workspace
- [ ] Workspaces persist after tool instance deletion
- [ ] Existing clone_mode instances migrate to workspace on restart
- [ ] UI no longer shows "mount vs clone" toggle
- [ ] New sidebar navigation "Workspaces" exists
## Open Questions for Spec
1. ~~Should workspace deletion cascade-delete associated tool instances, or block?~~ **Answered**: Allowed with confirmation; cascade-delete tool instances
2. ~~Should workspace names be unique per-repo or globally unique?~~ **Answered**: Unique per project+repo; derived from project and repo names
3. ~~How do we handle the case where a workspace's branch is deleted from the remote?~~ **Answered**: On sync/update, detect and ask for confirmation to delete local workspace/branch
4. Should we validate the repo path exists before creating a workspace?

# Spec: Workspace-Based Tool Instances
## Status
| Field | Value |
|---|---|
| Phase | **Spec** |
| Based on | [Proposal](proposal.md) |
| Next | Design |
## Overview
Workspaces are persistent, writable local clones of Git repositories. Users create workspaces explicitly, then start tool instances on them. This replaces the current "mount vs clone" decision with a simple "pick a workspace" flow.
## Decisions
| Decision | Value |
|---|---|
| **Name** | "Workspace" |
| **Scope** | Unlimited per repository |
| **Auto-create** | No — explicit creation only |
| **Delete with instances** | Allowed with confirmation; stops and deletes all associated tool instances |
| **Name uniqueness** | Unique per project+repo; derived from project and repo names |
| **Deleted remote branch** | On sync/update, detect and ask for confirmation to delete local workspace/branch |
## Database Schema
### New Table: `workspaces`
```sql
CREATE TABLE workspaces (
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
name VARCHAR(255) NOT NULL,
repo_id UUID NOT NULL REFERENCES git_repositories(id) ON DELETE CASCADE,
user_id UUID NOT NULL REFERENCES users(id) ON DELETE CASCADE,
branch VARCHAR(255) NOT NULL DEFAULT 'main',
path VARCHAR(2048) NOT NULL,
status VARCHAR(16) NOT NULL DEFAULT 'ready',
last_sync_at TIMESTAMP WITH TIME ZONE,
created_at TIMESTAMP WITH TIME ZONE DEFAULT now(),
updated_at TIMESTAMP WITH TIME ZONE DEFAULT now(),
UNIQUE (repo_id, name)
);
CREATE INDEX idx_workspaces_repo_id ON workspaces(repo_id);
CREATE INDEX idx_workspaces_user_id ON workspaces(user_id);
CREATE INDEX idx_workspaces_status ON workspaces(status);
```
### Updated Table: `tool_instances`
```sql
ALTER TABLE tool_instances
ADD COLUMN workspace_id UUID REFERENCES workspaces(id) ON DELETE SET NULL,
ADD COLUMN clone_mode VARCHAR(16); -- deprecated, nullable for migration
-- Drop existing clone_mode column after all instances are migrated
-- ALTER TABLE tool_instances DROP COLUMN clone_mode;
```
Note: `tool_instances.branch` remains for now but is deprecated; the canonical branch lives on the workspace.
## Backend API
### Workspaces API
```
GET /projects/{project_id}/repositories/{repo_id}/workspaces
→ List workspaces for a repository
POST /projects/{project_id}/repositories/{repo_id}/workspaces
→ Create a new workspace
Body: { name: string, branch: string }
GET /projects/{project_id}/repositories/{repo_id}/workspaces/{workspace_id}
→ Get workspace details
PATCH /projects/{project_id}/repositories/{repo_id}/workspaces/{workspace_id}
→ Update workspace (rename, change branch)
Body: { name?: string, branch?: string }
DELETE /projects/{project_id}/repositories/{repo_id}/workspaces/{workspace_id}
→ Delete workspace (with ?force=true to skip confirmation)
→ Stops and deletes all associated tool instances
POST /projects/{project_id}/repositories/{repo_id}/workspaces/{workspace_id}/sync
→ Sync workspace with remote (detect deleted branches)
```
### Tool Instances API (Updated)
```
POST /projects/{project_id}/repositories/{repo_id}/instances
Body: { tool_type_id, workspace_id, display_name?, config_profile_id? }
→ Create instance on workspace
POST /projects/{project_id}/repositories/{repo_id}/instances/{instance_id}/start
→ Start instance (creates workspace if mount_mode, migrates if clone_mode)
```
### Instance Start Logic
```python
def start_instance(instance, workspace_id=None):
if instance.clone_mode == "clone":
# Migrate: extract clone to workspace
workspace = migrate_clone_to_workspace(instance)
instance.workspace_id = workspace.id
instance.clone_mode = None
elif instance.workspace_id:
# Already using a workspace
workspace = get_workspace(instance.workspace_id)
else:
# Legacy mount_mode: create workspace on first start
workspace = create_workspace_from_repo(instance.repo)
instance.workspace_id = workspace.id
# Mount workspace path into container
mount_path = workspace.path
# ... rest of start logic
```
## Frontend Routes
```
/workspaces → Workspaces list page
/workspaces/new → Create workspace flow
/workspaces/{id} → Workspace detail page
/workspaces/{id}/tools → Start tool on workspace
```
## UI Components
### Sidebar Navigation
```
Projects
└── [project list]
Workspaces (NEW)
└── All Workspaces
└── [recent workspaces]
Settings
```
### Workspaces Page
- Grid/list of workspace cards
- Each card shows: name, repo, branch, status, active instances count
- Actions: Start Tool, Sync, Settings, Delete
### Create Workspace Flow
1. **Repo picker**: Select from existing repositories
2. **Branch picker**: Select branch (default: repo's default branch)
3. **Name input**: Auto-suggested as `{project-name}-{repo-name}-{branch}` but editable
4. **Create**: Clone repo to `/data/working-copies/{repo-id}/{name}/`
### Start Tool from Workspace
1. **Tool picker**: Select tool type
2. **Config**: Optional config profile
3. **Create**: Instance created with workspace mounted
## File System Layout
```
/data/working-copies/
└── {repo-id}/
└── {workspace-name}/
└── .git/
└── [repo files]
```
## Workspace Lifecycle
### Creation
1. Validate name uniqueness per repo
2. Clone repo: `git clone --branch {branch} {remote_url} {path}`
3. Set status to `ready`
4. Return workspace record
### Deletion
1. Check for running tool instances
2. If instances exist and no `?force=true`:
- Return 409 Conflict with `{ instances: [...] }`
- Frontend shows confirmation dialog
3. If confirmed:
- Stop all associated instances
- Delete all associated instances
- Delete workspace directory
- Delete workspace record
### Sync
1. Fetch from remote: `git fetch origin`
2. Check if workspace branch still exists on remote
3. If branch deleted:
- Return 409 with `{ branch_deleted: true }`
- Frontend asks: "Branch '{branch}' was deleted. Delete this workspace?"
4. If branch exists:
- Pull changes: `git pull origin {branch}`
- Update `last_sync_at`
## Migration Strategy
### Existing clone_mode Instances
```python
def migrate_clone_to_workspace(instance):
# Find the cloned repo inside the instance directory
clone_path = find_clone_in_instance_dir(instance)
# Create workspace
workspace = Workspace(
name=f"{instance.name}-migrated",
repo_id=instance.repository_id,
user_id=instance.owner_id,
branch=instance.branch or "main",
path=f"/data/working-copies/{instance.repository_id}/{instance.name}-migrated",
)
# Move clone to workspace path
move(clone_path, workspace.path)
return workspace
```
### Existing mount_mode Instances
On first start after deployment:
1. Create workspace from canonical repo
2. Update instance to use workspace
3. Remove clone_mode flag
## Acceptance Criteria
- [ ] Database migration creates `workspaces` table
- [ ] Database migration adds `workspace_id` to `tool_instances`
- [ ] API endpoints for CRUD operations on workspaces
- [ ] Workspace creation clones repo to `/data/working-copies/...`
- [ ] Workspace deletion stops and deletes associated tool instances

- [ ] Frontend workspaces list page
- [ ] Frontend create workspace flow
- [ ] Frontend start tool from workspace
- [ ] Existing clone_mode instances migrate on restart
- [ ] Existing mount_mode instances create workspace on restart
## Quality Gates
- [ ] Backend tests: workspace CRUD, sync, deletion with instances
- [ ] Frontend tests: workspace list, create, start tool
- [ ] Integration tests: instance creation with workspace
- [ ] ruff clean
- [ ] TypeScript compilation clean
