+- **`UpOptions.AdoptExisting`** — on resume, reattach a compose project's existing
+  containers exactly as they were left: start them if stopped, attach if running,
+  never recreate. The primary service's feature-layered image is rebuilt on every
+  boot with a fresh digest, so the config-hash always drifted and `ensureService`
+  recreated the container — abandoning its writable upperdir and binding a new empty
+  anonymous volume, which is where the in-container `$HOME` and a database service's
+  data live. The flag is threaded to `compose.Plan` and gated to non-recreating Ups;
+  the default path (hash-based reuse or recreate) is unchanged. (#120)
