Merge pull request 'A merge moves a module only when its build source holds a changed file (hq ADR 0267, issue 363)' (#193) from fix/0267-a-merge-moves-what-its-build-source-holds into main

A plan that closed without building a module hid a missed merge from it;
a window of recent plans let an old closure back in once the plan that
overtook it slid out; a merge the forge gave no time was acted on again
every pass. A plan answering the merge's own commit is now a look at it,
and clocks a little apart do not make a merge history.

+// operator's account there. A machine is **root-free** — an answer proven there may authorise — only when all

+//
+//  1. the machine names an account agents run as (novox/hq ADR 0266), so no agent runs as the operator's
+//     account, which may become root;
+//  2. its node-engine — running as root, which no agent controls — judged that account unable to become root
+//     without a person, in a statement heard within the last 15 minutes (agentConfined, judgedConfined). The
+//     engine gives that verdict only from a complete search for setuid programs younger than mesh-host's
+//     rootsearch.FreshFor; before one, it says "not judged yet", which is no pass (novox/hq issue 361);
+//  3. the login shell's `execute` is not served there (novox/hq ADR 0268): its holder's setting withholds it
+//     **and** the bus was asked and heard no `execute` answered there. `execute` runs commands as the machine's
+//     runtime account, which the mesh's acting tools give passwordless sudo; that account is taken to become
+//     root, always, so no measure of it is asked.
+//
+// **Nothing else is a pass.** A machine that names no agent account, an unknown machine, a store or bus that
+// could not be read, a verdict stale or absent — each is not root-free, and says why. The sudo module's own
+// measure is no longer part of this judgement: it ran in the machine's runtime, as the very account an agent
+// could become, so it could not be believed.
+//
+// The one judgement (judgeRoot) is read two ways: the self-check raises `root-not-free` on every machine where
+// the router or a module of its own account runs and the judgement fails; and the `root-free` verb answers it
+// live, to the router, which honours a verified sender only on its pass. A machine holding the operator's
+// graphical session, where a messaging client's desktop app may run, is not judged here: the operator accepted
+// that gap for now (hq issue 344).
