+ * No docker/db imports, so it's unit-testable with fakes.
+ *
+ * A redeploy recreates containers with new ids, orphaning the pending rows (keyed by
+ * old id). We clear a row ONLY when the container provably runs the newest local
+ * image for its tag — a pull can fail, so every ambiguity KEEPs the row (never hide
+ * a real update).
