## Problem
`app/components/__tests__/navigation-history.test.tsx`,
`TaskDetail.swipe-back.test.tsx`, and
`TaskDetail.mobile-transition.board-panel.test.tsx` fail to load.
FN-8796 (`132026545`, "stabilize task-detail lifecycle snapshots") added
`mergeTaskSnapshot` to `hooks/useTasks.ts`, which
`App.tsx`/`MainContent.tsx` now import. The curated test suites that
`vi.mock("../../hooks/useTasks")` still only expose `useTasks`, so the
fixture throws at import time:
```
No "mergeTaskSnapshot" export is defined on the useTasks mock
```
Confirmed on `origin/main`: `mergeTaskSnapshot` is present in
`useTasks.ts` and imported by `App.tsx`, while these tests' `vi.mock`
shims don't surface it.
## Fix
Update the mocks to surface every export the rendered components import,
using a partial `importOriginal` mock so `mergeTaskSnapshot` keeps its
real implementation (a `vi.fn()` returning `undefined` would make
`App.tsx:2179` `liveTask.id` throw):
```ts
vi.mock("../../hooks/useTasks", async (importOriginal) => {
const actual = await importOriginal();
return { ...actual, useTasks: (_options?: any) => mockUseTasks() };
});
```
## Verification
- `FUSION_DASHBOARD_DEEP=1 vitest run navigation-history swipe-back
board-panel` → **14 files, 116 tests passed**
- Pre-existing on `origin/main`, fixes a regression introduced by
FN-8796.
## Scope
Tests + a one-line docs note only. No production behavior change.

## Summary by CodeRabbit
- **Documentation**
- Documented improved worktree recovery behavior, including safer
handling of incomplete, inactive, and unregistered directories.
- Added guidance for recovery across different storage locations and
bounded cleanup of recognized entries.
- Clarified protections that prevent internal recovery containers from
being treated as worktrees.
- **Tests**
- Improved dashboard test coverage and reliability for task detail
rendering, mobile transitions, swipe-back navigation, and navigation
history.
