+// numbers), NOT via proton — so asserting `proton.encode(...) === pb.env(...)`
+// goes red if a proto-defs field tag is wrong or silently changes. A
+// symmetric encode→decode round-trip can't catch a tag swap; this can.

+// Emission rules mirror proton's observed behaviour: fields in ASCENDING
+// tag order, and proto3 defaults (0 / '' / false) OMITTED.
