registry package

Overview

Package registry is spike (a) of tasarim-v6 §5.5: can a realm store an interface value handed over by ANOTHER realm and call it later, and what can that foreign code do to the registry while it runs?

It is deliberately tiny and is never part of the product. Two exports are intentionally unsafe probes and are marked as such: SharedBoard (returns a pointer into registry state) and UnsafeBump (a non-crossing exported mutator). Production core has neither; this spike measures why.

Function

SharedBoard

func SharedBoard() *Board
Ask AI Claude ChatGPT

SharedBoard returns a pointer into registry state. UNSAFE PROBE: the spike checks that a foreign engine writing through it is refused by the VM (interrealm v2 §3.2 readonly check).

Command

gnokey query vm/qeval -remote "https://rpc.onyx.testnets.gno.land" -data "gno.land/r/g19dzk54hhsdc3gllpksuj6gu4a3e6fl8cr6rn4w/minhwa/spike/registry.SharedBoard()"
