API Notelet tracks the operator's side of an API deprecation, not the marketing side.
Write what is dying and when, map every consumer who must move, record the day you notified them, and track the state from announced to migrated. Four quality gates and a readiness score keep a note honest - a deprecation nobody was told about is a surprise outage with a date on it - and urgency bands count down what is overdue, critical, soon, or later.
Export the notelet card, a consumer warning note, or a Markdown ledger row. Everything stays local: no account, no sync, nothing leaves the browser.
