# Task 3 Report: Workbench Shell, Project Rail, Channel Sidebar, And Topbar

## Status

Implemented the Task 3 workbench shell and integrated it with the authenticated application state.

## What Changed

- Added `ProjectWorkbench.svelte` to compose the workspace topbar, project rail, project channel sidebar, channel stage, and object inspector.
- Added `ProjectRail.svelte` with accessible project buttons, selected state, unread counts, dashboard, and create-project controls.
- Added `ProjectChannelSidebar.svelte` with project metadata, tags, channels, selected state, and recent sessions.
- Added `WorkspaceTopbar.svelte` with a global search input, navigation controls, and account button.
- Replaced the signed-in placeholder in `App.svelte` with `ProjectWorkbench`.
- Added `ProjectWorkbench.test.ts` to verify the accessible shell landmarks and project switching behavior.

## TDD Evidence

1. Created `ProjectWorkbench.test.ts` before the workbench components existed.
2. Ran `npm test -- --run src/features/workbench/ProjectWorkbench.test.ts` from `apps/web`.
3. Confirmed the expected red failure: Vite could not resolve `./ProjectWorkbench.svelte` because the component had not yet been created.
4. Implemented the shell components and application integration.
5. Re-ran the focused test and confirmed 2 passing tests.

## Tests

- `npm test -- --run src/features/workbench/ProjectWorkbench.test.ts` - passed: 1 test file, 2 tests.
- `npm run build` - passed: Vite production build completed successfully.
- `git diff --check` - passed: no whitespace errors.

## Files Changed

- `apps/web/src/app/App.svelte`
- `apps/web/src/features/workbench/ProjectWorkbench.svelte`
- `apps/web/src/features/workbench/ProjectRail.svelte`
- `apps/web/src/features/workbench/ProjectChannelSidebar.svelte`
- `apps/web/src/features/workbench/WorkspaceTopbar.svelte`
- `apps/web/src/features/workbench/ProjectWorkbench.test.ts`

## Self-Review

- The implementation consumes `workbenchProjects` and `getProjectWorkspace` from the existing Task 2 model.
- Selected project buttons expose `aria-pressed`; the sidebar, project rail, global search, and inspector expose the required accessible names.
- Changing the project updates the workspace channels and resets the selected channel to the project's first channel.
- No channel-specific content templates or dependencies were added.
- Changes are limited to the task brief's application and workbench files; this report is the separately requested deliverable.

## Concerns

None. The existing Vite setup reports that no Svelte config is present, but the focused test and production build both pass.
