 ## Credentials
 
 The conversation that creates an automation remains its execution conversation.
-Every script launch uses that conversation's T44 chain.
-The chain includes ownership, fork ancestry, and the optional branch starter.
+Every script launch uses `host.chain(creator)`.
+The host delegates to `conversationChains` in `host/js/environment.ts`.
+The host appends the branch starter's chain after the ownership or fork ancestry.
+The host removes duplicate ids without changing their order.
 Subscribe and unsubscribe change notification recipients only.
 They never change the execution conversation.
 Built-in automations without a creator use an empty chain.
