# #1408: the reconciler writes projections into the BRAIN home when one is

# resolution), and into MOSAIC_HOME on a legacy single-tree host. A single
# config-home condition therefore skipped every seat on brain-home estates —
# measured on two estates: 27 projections vs 0, and 5 vs 0, gate never fired.
# Two TRIGGERING conditions (the `|` prefix ORs same-type conditions, which
# otherwise AND): either shape arms the unit; the launcher still resolves the
# authoritative copy itself.
