nslogic/v2 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.

Function

SetLabelPattern

func SetLabelPattern(cur realm, pattern string)
Ask AI Claude ChatGPT

SetLabelPattern no longer changes anything, and refuses anything but the rule this realm actually implements.

It used to compile an arbitrary regex and store it, with validateLabel reading it back. That flexibility cost 15 GNOT of permanent storage per deploy — see the measurements in validate.gno — for a rule that has never changed and should not change casually.

It is kept rather than deleted so that an admin who reaches for it gets told what happened instead of a "function not found". And it refuses a different pattern rather than accepting one it will not enforce: a stored string describing rules the code does not apply is the exact silent divergence the caching version was written to avoid.
