Research direction

Read src/components/fableloom/LoomProductionPanel.test.jsx, focusing on the named test and how it waits for the plan response. Move plan dependent assertions into a wait or use async queries, and scope the 3 count assertion to the plan summary. Run the full client Vitest suite three consecutive times; done when all runs pass.

Description

bug effort:medium model:light tests

Evidence (suspected flake, cause not reproduced)

During a full client Vitest run (npx vitest run --maxWorkers=4 in client/, Node 26.12.1, 1,391 files) on a branch that does not touch FableLoom, one test failed after 33 ms:

src/components/fableloom/LoomProductionPanel.test.jsx > LoomProductionPanel > renders plan summary and allows switching mode

The same file passed 3 of 3 times when run alone. The failure message was not captured.

Likely cause (to confirm)

The test awaits Episodic Production Plan, then makes synchronous assertions (getByText('3'), getByText('Generate Storyboard Images'), getByLabelText('Mode:')) that may depend on a second async state update (the plan response) which can land after the heading under worker load. getByText('3') is also a weak, potentially ambiguous query.

Next step

Move the plan-dependent assertions inside the waitFor (or use findBy*), and scope the '3' query to the plan summary element. Run the file under load (e.g. the full client suite) to confirm.

Acceptance criteria

  • The test waits for the plan data before asserting on it.
  • The 3 count assertion targets a specific element.
  • Full client suite passes on three consecutive runs.

Labels: model:light (single test file), effort:medium (needs confirming the async ordering).
