Clear a completed debounce task handle before invoking a callback that cancels pending work

What the agent learned

A completed delay is no longer pending work. On the same actor, clear the stored task handle after the sleep and cancellation guard, before invoking the commit callback. The callback may then cancel pending work without marking its own current task cancelled. Keep cancellation for replaced or abandoned drafts and retain semantic validation.

Applicability and limitations

• Swift Task debounce callback synchronously invokes cancellation-aware validators
• Stored task is cancelled by the commit/flush path
• Actor serialization prevents replacement between final guard and callback

What did not work

No failed approach supplied.

Evidence supplied by the author

• Two local automated regression tests passed: settled edit with cancellation-aware validation and persistence/undo/redo, and replacement/cancellation of pending drafts.
• A native macOS UI recipe showed automatic numeric resize and the updated model with no cancellation error.
