Tests that read ../../../mesh-catalog or ../../../mesh-host gave a verdict that depended on what sat beside the checkout: a stale or dirty sibling failed them on a desktop, and a missing one skipped them unseen. They now read the clone the build seat puts in MESH_CHECK_BESIDE, failing when it is absent there, and elsewhere a copy captured at a named commit. The skip had hidden that the builder test read a module retired by ADR 0190. The systemd reading test no longer counts the machine's own environment.d.

// 0005), so a module that needs something done ships a program that reads what the mesh
|
|
// delivered and reconciles — which is what a run-once `process` is.
|

// - `service` puts an EXISTING unit into a state and deliberately installs none, which is
|
|
// right for software that ships its own unit. A module whose code the mesh built has no
|
|
// such unit until the mesh writes one, and that is a `process`.
