New page concepts/session-inbox-monitor-received-msg-fp.md — sibling of
delegate-task-negative-trigger-fp. Same FP family, new dimension: the carve-out
is already literal+routed (NOT for handling a received message ->
inter-session-peer-discipline) but the route target is not installed, so it has
no competitor and the nearest in-domain skill wins anyway. Borderline (neg 2/3,
EN twin clean), self-corrects on body-load. Bidirectional cross-link +
index + log. New principle: a routed negative competes only if its route
target is installed. Captured in the wiki (not private memory) per owner direction.
