+# Seed an IN-MEMORY stand-in for a vd03-style machine with a composed DelmiaReceiver on
+# site-a, so DelmiaNotifier can be exercised end-to-end on the docker rig without a Galaxy.
+#
+# What it creates (all static attributes — no data connection, no bindings):
+#   - Template DelmiaReceiverSim — the ten DelmiaReceiver attributes from prod
+#       (docs/api-specs/Delmia-Recipe-Download-API.md §5), ReadyFlag defaulting to true.
+#   - Template SimMachine — composes DelmiaReceiverSim as `DelmiaReceiver` and carries
+#       * ProcessRecipeDownload (Call)  — prod's handshake ported to per-attribute
+#         SetAsync/WaitAsync (WriteBatchAndWaitAsync rejects static attributes).
+#       * DelmiaReceiverSimulator (ValueChange on DelmiaReceiver.RecipeDownloadFlag) —
+#         plays the Galaxy object: accepts unless DownloadPath ends in ".bad" or the work
+#         order is blank, writes RecipeProcessResult/Text, clears the trigger flag, then
+#         sets RecipeProcessedFlag=true.
+#   - Instance DelmiaSim01 on site-a (id 1), deployed.
+#
+# Not idempotent: names must be unique. To re-seed:
+#   scadabridge instance delete --id <id>; scadabridge template delete --id <SimMachine id>;
+#   scadabridge template delete --id <DelmiaReceiverSim id>
+# Prerequisites: bash docker/deploy.sh; docker/seed-sites.sh; central healthy on :9000.
