+# /fusion · /auto-validate · /opinion — fuse two frontier models (AND, not OR).
+# The HOST runs on the BUILDER model: raw (non-slash) input IS the builder agent.
+#
+# Two launch recipes, two tiers — everything else is a flag:
+#
+#   just fh-workhorse    cheap pair (sonnet-5 plans · terra builds + hosts) — use for testing
+#   just fh-sota         frontier pair (fable-5 plans · sol builds + hosts) — the on-camera run
+#
+# Configuration flags (all optional, appendable to either recipe):
+#   --architect <provider/id>              plans/fuses/validates
+#   --builder <provider/id>                builds
+#   --architect-thinking <level>           EVERY architect-family execution
