 ## Unreleased
 
+- `test/changelog-assembled.test.sh` — keep the trio interaction aligned with fragment mode: a dropped entry makes armed red too, while a hand-edited section leaves assembled as the sole red (#126).
 - `changelog-armed` — treat `changelog.d/` as the arming, validate every development fragment, and require bare releases to consume the directory into their exact publishable section (#115).
 - `actions/changelog-assembled` — a release PR's stamped section must be byte-for-byte what the fragments it consumed assemble to, replayed from the merge base; inapplicable trees pass with a NOTICE (#116).
 - `lib/changelog.sh` + `bin/changelog-assemble` — read the `changelog.d/` fragments, assemble one release section (canonical group order, one shape per repo), and consume exactly what was published (#114).
