# Verify cancellation removes a pending reminder

Exercise a sandbox event cancellation before a prepared reminder deadline, checking visible cancellation and the independent delivery queue outcome.

## Risk

A cancelled event can remain in an already queued reminder job. The test must cross the dispatch boundary with an externally controlled clock and inspect the delivery sink; a cancelled badge alone cannot prove cancellation propagation.

## Fixtures

- An owned sandbox calendar with a disposable event and reminder queued but not yet due.
- An external scheduler clock fixture prepared immediately before the dispatch boundary and a sandbox-only notification sink.
- A read-only event and job oracle recording event identifier, reminder identifier, and baseline queue state.

## Steps

1. Open the prepared event and verify its active status and configured reminder time match the queue fixture.
2. Cancel the event through the product confirmation and verify its detail clearly shows Cancelled.
3. Advance the external scheduler fixture beyond the reminder boundary and verify its report confirms the dispatch cycle completed.
4. Inspect the independent queue and sink, and verify the reminder is cancelled or safely suppressed with no delivered message for the event; reopen the event and verify it remains cancelled.

## Expected results

- The event cancellation persists before the documented dispatch cutoff.
- The reminder job is cancelled or suppressed under the product policy.
- The sandbox delivery sink receives no notification for the cancelled event after a completed dispatch cycle.

## False-pass traps

- An empty sink before the dispatch cycle runs proves nothing about future delivery.
- Deleting only the calendar display row can leave a live queued reminder behind.

## Cleanup

- Remove the cancelled fixture event and restore the external scheduler clock baseline.

## Use with agent-qa

Adapt this test design to your application's acceptance criteria and configured target using the [recipe execution guide](/agent-library/software-factory/turn-a-recipe-into-an-agent-qa-test.md). External fixture setup and non-UI checks require your own supported hooks or test tooling. Validate the authored test, execute it, and inspect the completed evidence; this recipe is not a recorded test result.
