+Delete sections that don't apply. The prompts are here to make review
+faster, not to add ceremony -- one sentence per section is often enough.

+
+## Motivation
+
+<!--
+Why now. Link the issue, incident, user report, or parent PR. If this
+is preparation for another change, name it. If it's cleanup, say what
+prompted it.
+-->
+
+## Behavior change
+
+<!--
+For users of the library or CLI: what changes in observable behavior?
+"None -- refactor only" is a valid answer. If a public symbol, endpoint
+signature, exception type, or return value shape changes, call it out
+here and in the CHANGELOG so downstream code isn't surprised.
+-->
+
+## Test plan
+
+<!--
+What's exercised by the tests in this PR. If any behavior claim in the
+description ISN'T covered by a test (e.g. "verified manually against a
+live server", "matches server behavior at REST endpoint X"), say so
+explicitly so reviewers know what's on trust vs. what regression tests
+will catch.
