nslogic/v1 package

Overview

Package nslogic is the swappable "business rules" half of the split (NOTES.md §9t). It holds every piece of policy that might reasonably change — pricing, character validation, payment/refund, freeze rules, transfer restrictions — and no persistent records of its own. (One throttle, not a record: when each bounded price setting last moved, timelock.gno's lastTweak. A logic swap starts it empty and loses nothing.)

Every mutation here ends by calling into nsdata's narrow Record/Raw API via cross(cur). nsdata trusts whichever address is currently wired up as trustedLogic to have done its own authorization checks correctly, so THIS realm is where "is the caller allowed to do this" actually lives. If a bug is found here, admin deploys a fixed nslogic and re-points the vault at it (ProposeTrustedLogicGrant, then ExecutePending after the timelock) — no data migration, records and config untouched.

Deliberately reads config fresh from nsdata on every call rather than caching it. The one thing that cannot be read fresh is a COMPILED regex — avl trees store the pattern string, not the compiled object — so that one value is cached, and the cache is validated against nsdata on every use.

Ask AI

ResolveAddress performs reverse resolution: address -> name.

It must verify the ownership it is asserting, not merely that the pointed-at name exists and is unexpired. nsdata's `primary` tree is a record of what an address last SELECTED, not proof of what it still owns — and although nsdata now clears the pointer on transfer and reclaim, this check is the half that lives in the swappable realm and therefore stays correct even against pointers written by an older version of the logic. Without it, an address that sold or lost a name kept reverse-resolving to it, impersonating the new owner.
