+# Local Oracle AI Database for development.
+#
+# This uses the freely-pullable Oracle Database Free image, which includes AI
+# Vector Search (what oracleagentmemory relies on). It is provided as a
+# convenience — if it doesn't match your environment, Oracle's official guide is
+# authoritative:
+#   https://docs.oracle.com/en/database/oracle/agent-memory/26.4/agmea/run-locally.html
+#
+# First boot takes a few minutes while the database is created; watch progress
+# with `docker compose logs -f oracle-db` and wait for "DATABASE IS READY TO USE".
