 For these two the allowlist is not an optimization but the whole gate, per the rule above: a prompt is not a substitute and MUST NOT be offered, because consenting to an opaque message is not meaningful consent. **The interim fallback of the previous paragraph does not apply here** — the consequence is that foreign proofs and foreign signatures are simply **unavailable until the manifest RFC lands**, since there is nowhere yet to express the allowlist.

 **Environment moves.** Pointing a product at a different environment (a new testnet iteration, a devnet) means editing constants and shipping a new build, even though the host-side change is a config edit.
 
-The fix is to make the host's chain set discoverable over the wire.
