-# **Built from this module's own directory and nothing else.** The sdk and the tool runtime are in
-# the base images, published like any other artifact — which is what makes this buildable by the
-# mesh from a repository and a path (novox/hq ADR 0069) rather than only on a workstation that
-# happens to have the siblings.
-#
-# Two bases, named rather than pinned (novox/hq issue 044): the image this is COMPILED in and the
-# image it RUNS in — the second must not carry a compiler. Declared in module.json's `build.on`.

-# node_modules — the module is compiled against exactly the sdk it will run against. The compiler
-# is invoked by its real path: node_modules/.bin entries are launcher symlinks the base image
-# resolved away.
