+## What and why

+<!-- Normal description for reviewers. -->
+
+## Impact
+
+<!--
+Fill the block below. It is the only place "what does a customer notice, and
+why did we do this" is ever cheap and accurate, because you know it right now
+and a diff cannot answer it later.
+
+`significant: false` is a complete answer and needs nothing else. Use it for
+internal renames, behaviour-preserving refactors, formatting, editorial doc
+edits, tests, dependency bumps, build changes, and internal logging.
+
+Use `significant: true` when someone outside the team could notice without
+reading the code: a new or removed endpoint, field, screen or permission; a
+changed request or response shape; the same call returning something different;
+changed limits, quotas, timeouts or price; accuracy or latency changed enough to
+alter a published claim; changed supported regions, integrations or client
+versions; changed authentication, retention or what data is collected.
+
+It is not a size test. A one-line rate-limit change counts. A thousand-line
+refactor that preserves every behaviour does not.
