Patch useTasks pauseTask/unpauseTask to update local hook state and the project SWR task cache immediately on API success, instead of waiting for SSE/poll to reconcile paused state. - pauseTask/unpauseTask now bump fetchVersionRef, patch the in-memory tasks list, and patch/clear the project SWR cache the same way retryTask/bypassReview already do - guards against stale in-flight fetches clobbering the just-applied paused/unpaused state and against missing-id cache entries - adds regression tests covering immediate local+cache reflection for pause and unpause, stale in-flight fetch ordering, and missing-id stability - adds a patch changeset documenting the user-facing fix Files changed: .changeset/fn-7861-immediate-pause-state.md | 7 + .../dashboard/app/hooks/__tests__/useTasks.test.ts | 151 +++++++++++++++++++++ packages/dashboard/app/hooks/useTasks.ts | 66 ++++++++- 3 files changed, 222 insertions(+), 2 deletions(-) Fusion-Task-Id: FN-7861 Fusion-Task-Lineage: fefbaf4f-8eb7-44a7-a1e2-ac8471a726bd Co-authored-by: Fusion (runfusion.ai) <noreply@runfusion.ai>

/**
|
|
* EventSource Mock Cleanup Requirements:
|
|
*
|
|
* This test file uses a MockEventSource class that tracks all instances in a static
|
|
* `instances` array. To prevent test isolation issues, we must ensure:
|
|
*
|
|
* 1. `MockEventSource.instances` is reset to empty before each test
|
|
* 2. Any lingering EventSource instances are closed and removed after each test
|
|
* 3. Fake timers are restored to real timers after each test (in case a test failed
|
|
* before it could restore them)
|
|
* 4. The reconnectTimer from useTasks hook (3000ms) is cleared by closing all
|
|
* EventSources in afterEach
|
|
*
|
|
* Without proper cleanup, fake timers from one test can leak to subsequent tests,
|
|
* causing `waitFor()` calls to hang indefinitely.
|
