# Data Model: Workspace Switch Semantic Fix

**Feature**: 121-workspace-switch-fix | **Date**: 2026-03-07

## Overview

This feature does not add or modify database tables. It corrects the navigation contract between three existing workspace-related concepts:

1. the topbar `Switch workspace` entry,
2. the canonical workspace chooser,
3. the separate workspace management destination.

## Existing Entities / Concepts

### Workspace switch entry (UI affordance)

| Attribute | Value |
|-----------|-------|
| Surface | Admin context bar / topbar partial |
| Current problem | Routes to workspace management instead of chooser |
| New contract | Routes to the chooser using the existing forced-switch convention |
| Mutation | None |

### Workspace chooser

| Attribute | Value |
|-----------|-------|
| Backing page | `App\Filament\Pages\ChooseWorkspace` |
| Route slug | `/admin/choose-workspace` |
| Purpose | Explicit manual workspace selection |
| Existing behavior | After selection, consumes intended URL or resolves redirect via `WorkspaceRedirectResolver` |

### Workspace management destination

| Attribute | Value |
|-----------|-------|
| Backing resource | `App\Filament\Resources\Workspaces\WorkspaceResource` |
| Purpose | Workspace CRUD / administrative management |
| Access model | Existing capability-aware workspace management rules |
| Change in this feature | None |

## Relevant Existing State

### Session-backed workspace context

| Key | Type | Notes |
|-----|------|-------|
| `current_workspace_id` | int | Active workspace context used across the admin plane |
| intended workspace URL | string/null | Existing post-selection return path managed by `WorkspaceIntendedUrl` |

### Existing redirect semantics

```text
Switch intent
  -> ChooseWorkspace (`?choose=1` forces chooser)
  -> User selects workspace
  -> WorkspaceIntendedUrl::consume() if present
  -> else WorkspaceRedirectResolver::resolve()
```

## Validation / Rules

| Rule | Result |
|------|--------|
| Intentional workspace switching must target chooser | Required |
| Intentional switching must not target workspace CRUD | Required |
| Workspace management remains separately reachable | Required |
| Existing membership/capability enforcement remains unchanged | Required |
| Existing post-selection redirect behavior remains unchanged | Required |

## State Transition

```text
[User on admin page]
    |
    | click "Switch workspace"
    v
[Chooser page displayed]
    |
    | select workspace
    v
[Existing intended URL or resolved workspace landing]
```

No new persistence state is introduced.
