Window 3 Notification Language Guidance
Window 3 does not notify you of a resolution; it notifies you that your expectation of a resolution has been successfully logged.
The ideal notification language is one that makes the recipient apologize for having received it.
Clarity is a liability when you are legally obligated to provide an update but procedurally forbidden to provide an answer.
A well-crafted Window 3 notification contains exactly enough information to prevent follow-up questions, and not a syllable more.
The tone must always imply that the system is doing you a massive favor by acknowledging your existence.
