114# Run a standalone read-only Inspector body with its own Instance cursor.
115# Returns World and Instance on both body success and failure. Success advances
116# World clock and observation cursor; failure retains the prior cursor. Neither
117# path advances a registered system cursor or owns event retention. This raw
118# Instance has no world namespace check; canonical runtime-bound wrappers
119# enforce their separate registration/world contracts. Trusted projections
120# must preserve owners; arbitrary host effects are not automatically rolled back.
121# Inspection contract and consumers: docs/parity/inspect.md.
