// Package layoutroutingsecurity provides the strict-v2 physical table shapes
// for the identity/permission authority's current runtime routing-security
// binding, immutable attestations, and immutable canonical view artifacts.
//
// The package recognizes only two fixed table pairs: the future canonical live
// pair and one halted-migration shadow pair, plus one fixed canonical-view
// table in each mode. Callers cannot provide table names. The shadows can be
// created explicitly for an offline halted migration; this package is not wired
// into normal startup or a serving read path.
