A line in postgres's recipe and a one-line file in amqp-ping, both added to move a commit and watch the mesh notice. The proofs worked; neither was meant to stay. MESH_MODULE is set from the sealed credential at run time anyway, so baking it in was dead weight as well as noise.

# **Built from this module's own directory and nothing else.** The sdk is in the base image, so

# the siblings.

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