A module's runtime image was assembled by a script copying the sdk and the tool runtime out of neighbouring checkouts, so it could only be built on a workstation that had them. That is why no module declared what it was made of and why forty-seven point at a placeholder. The tool runtime becomes an image a module's runtime is built FROM, published like any other artifact. The module then builds from its own directory and that base — one clone, which is what the builder can actually be asked for (novox/hq ADR 0069). The dependency stops being a property of somebody's machine and becomes a build edge, pinned to a digest the mesh's registry assigned. The compiler is invoked by its real path rather than through node_modules/.bin: those are symlinks to a launcher that requires its library relatively, and resolving them while building the base leaves a launcher pointing at nothing.

# **Built from this module's own directory and nothing else.** The sdk and the tool runtime are not

# copied out of neighbouring checkouts — they are in the base image, which is published like any

# other artifact. That 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.

|
|
# The base is named by ARG so it can be pinned to a digest the mesh's registry assigned. A tag here
|
|
# would make the runtime's contents depend on what somebody last pushed under that name.
