+# **Built from this module's own directory and nothing else.** The toolkit is in the base image, so
+# nothing is copied out of a neighbouring checkout — which is what lets the mesh build this from a
+# repository and a path (novox/hq ADR 0069) rather than only on a workstation that happens to have
+# the siblings laid out beside it.
+
+# Two bases, named rather than pinned: the image this is COMPILED in, and the image it RUNS in.
+# They are different images on purpose — the first carries a compiler and the second must not, or
+# every running container would carry one it never invokes. The mesh answers both with the copies it
+# holds, because a fingerprint written here would name one particular copy and no other mesh has it
+# (novox/hq issue 044). Declared in module.json's `build.on`; deliberately no defaults, so a build
+# nobody told stops here and says which module to build first.
