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)
The control-node's walk takes far longer than the engine runs between
updates, so a search that starts over at every restart never completes.
The walk is the engine's own, in lexical order, so its progress is one
cursor per filesystem, kept every minute beside the engine's state and
carried on after a restart while younger than rootsearch.FreshFor. It runs
on a thread of its own at nice 19 and the idle I/O class.
A machine with millions of files never finished the walk within fifteen
minutes, so its agent account was never judged and the router refused to
link. Only root can make a setuid-root file, so a complete search stays
sound until root acts: it now runs at idle priority with no bound, is kept
beside the engine's state, judges for rootsearch.FreshFor from its start,
runs again daily and after an apply that moves accounts, packages, actions
or sudo rules, and an incomplete or stale search is never free.

The search kept a two-minute limit of its own inside its 15-minute bound, so
a long walk always ended incomplete; pacman was asked once per path; and find
exiting with an error but some output was read as a complete walk. The bound
and the not-judged reasons move to the public rootsearch package so the
controller reads the same values (the review of 2026-10-09).
