writeLaunchers takes its entrypoint-to-launcher names from buildstep.Launchers, the rule the
controller reads a bundle by. RecipeSteps goes to 2: a member is now built against the SDK
its own lock names, which can change what a build produces (ADR 0405 §7).
build_node_fetch takes buildstep.FetchRequest (dir and paths narrow the workspace) and an
optional package {repository, commit, ref}: the group's package member, built and packed
shut off and published nowhere. Each member's lock decides its SDK: the group's packed
file when the version and integrity are the lock's, else the registry's (integrity
checked); a version the registry lacks fails waits for: @novox/mesh-sdk@<version>. A
package artifact is built by its own script and packed with npm pack, shut off; only a
trunk build publishes it, from this process with the write credential (never in a
workspace): absent is published, the same file is done, another is version taken:. The
registry configuration file now lies outside every workspace.
After the build ended the module pushes the packed bundle with mesh-sdk's PushBlob under
<module>/<artifact> by its digest, a candidate's as a trunk build's, and the step answers
artifact-store://<module>/<artifact>/blobs/<digest> instead of the archive's path. A push
that fails fails the step not stored: <artifact>: <the store's words>; the packed bytes are
never written to the node. The manifest requires artifact-store and places its address.
Each run step goes through mesh-sdk's buildstep.Isolated: no network, none of the account,
the workspace read-write, the toolchain read-only, the npm cache beneath a throwaway layer
unless the build step is told publish (a trunk build). The module declares the bubblewrap
package and refuses a step, unhealthy, while bwrap is missing or older than 0.10. The proof
test runs a probe script through the real test step.
