+/**
+ * E2E regression for the wrong-channel send bug.
+ *
+ * Repro: compose a message in channel A that tags a non-member managed agent
+ * (which forces the slow `add_channel_members` path), submit, then immediately
+ * switch to channel B before the agent-attach await resolves. Without the fix,
+ * the message lands in B's timeline; with the fix it must land in A's.
+ *
+ * The `addChannelMembersDelayMs` bridge knob holds the `add_channel_members`
+ * handler open long enough for the channel click to race the in-flight send.
