## I assumed

an autosave timer cleared in the effect's cleanup would stop when the Compose window was sent, since the window goes away.

## What happened

after Send, the window stayed mounted while it animated out, so its pending autosave fired during the exit and saved the message that had just been sent back into Drafts.

## The fix

a `done` ref that send, discard and close set at the moment they happen, which clears the timer and turns any late timer into a no-op; the effect also skips scheduling once it is set.

## Evidence

commit 2e3b352; the comment "Once the window is sent, discarded or closed it saves nothing more, even while it animates out" in compose-window.tsx.
