mesh/merge-gate pass: builds mesh-host → ace, g14, novox, shanks; no bus step; every machine composes with the change as it did without (4 of 4 compose)
Two holes the review proved. The ask's subject proved nothing — a responder can reach it through a reply — so the engine now verifies the mesh's signature over a fixed context with the key it verifies declarations with, before reading anything, and refuses an ask for another node, expired, good too long, without a nonce, or replayed. And the apply followed a link the hand-over had refused: a component swapped for a link after the record carried root's chmod and chown to its target. A handed-over directory must now still resolve to itself, and is changed only through one descriptor opened from / with no link followed (fchmod, fchown). Tests for the reply guard, the run loop's hook, the fallback renewal on proof and a non-regular fallback; 27 checks each removed in turn, each failing a test.

The file on PATH was the engine a person copied at installation, and every delivered engine ran from the versions directory: the operator typed hand-over and a build from before it answered "unexpected argument". A proved engine now copies itself over that file when the bytes differ (never a link). And the hand-over of a directory used as found (issue 339) gets its channel: the controller's terminal asks this node's engine on mesh.node.<node>.ask.hand-over; the engine judges every value — the ask's size and shape, who asked, the path as it states it, a directory and no link, through no link — and records it or refuses and records nothing. Every text the engine addresses to the operator names the nox line (ADR 0272); the engine's own subcommands are install-time and rescue, and its usage says so.
