+# Release notes placement
+
+Read this during Phase 0 sorting.
+Assign every changelog entry one label.
+
+## Labels
+
+| Label | What to do |
+|-------|------------|
+| **Highlight** | New for this release. Intro bullet and featured section, with examples. |
+| **Brief include** | User-facing, not headline. Short bullet under Features, Upgrade, or Bug fixes. |
+| **Cite prior notes** | Already covered in an earlier X.Y. Mention it and link there. Do not rewrite. |
+| **Exclude** | Changelog only. |
+| **Uncertain** | Can't tell from the diff. Hold for human review. Do not exclude. |
+
+**Fold** is not a placement label.
+Several PRs that are the same change get one description and a list of PR numbers.
+Follow-up fixes cite the parent feature, not each fix.
+
+## Which pattern
+
+Default to a normal minor: most entries appear.
+
+When this release graduates work that earlier notes already documented,
+cite those notes.
+Keep this file for what changed now:
+now default or GA, breaking changes, and net-new items.
+
+Tempo 2.10 is a normal minor.
+Tempo 3.0 cited 2.9 and 2.10 for architecture work already documented there.
+
+## Always keep
+
+Breaking changes, Go upgrades, new config or flags, deprecations,
+and bugs users could have hit.
+
+## Exclude
+
+No user-facing effect once you check the diff, not just the label:
+tests and harnesses, docs-only, mixins and dashboards, vendor bumps,
+internal refactors, example-config-only, internal metrics plumbing.
+
+Can't tell from the diff? Label it uncertain, not exclude.
+
+## Sanity check
+
+On a normal minor, most chloggen entries should appear.
+If almost everything is excluded, revisit.
+Do not use a major-version cite-back pass as the omit rate for a minor.
