+// plan's, a release's, a healer's, a rotation's, and the bus step too, which is a person's act but composes under
+// sendKeeps like the rest. On 2026-10-02 two merges a minute apart made two plans;
+// the controller's plan rolled the new controller, which widened its seat's row, and the node-engine's plan then
+// sent the control node the controller build before it. The older binary read the row it could not serve and the
+// mesh lost its voice for ten minutes — the thing that would have corrected it was the thing that was down. ADR
+// 0185 took the outage out of it (a controller behind its row serves what it can); the race is closed here,
+// without needing its trigger: whatever made the mesh's record older, the send keeps the build.
+//
+// **Kept, not refused.** The send composes the controller or the node-engine at the build the machine was last
+// sent, as a recorded module is kept (ADR 0245), and carries everything else: no other module, secret, healer or
+// walk waits on it, and nothing is retried. The kept move is no move for a gate either: ungatedIn and gatedSend
+// leave it out (withoutKept), so a gate judges the other moves of its send. A plan whose own build is the older one finds its gate superseded by
+// the build kept there (issue 352) and ends. The mesh's record stays older, and a warning condition says so until
+// a send carries the record — a person's `push <node>` accepts the older build — or the record moves forward: a
+// newer merge, or `rebuild mesh-controller`.
+//
+// Older is by the builds' registration order — when each was asked (novox/hq issue 219) — never by the commits'
+// dates. So a retry or a rebuild of an old commit, asked anew, counts as newer: it is registered as the module's
+// current build by the same order, and the guard does not stop that move. A build that failed its gate is never
+// ahead: the machine was sent it and the record was put back before it (gateFailed), and if the put-back's own
+// send was refused, the next send completes it rather than keeping the failed build there. A gate's own put-back
