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.

Everything the profile page draws, in ONE read.

It was making seventeen queries: three to establish that the name exists and when it expires, then fourteen more — one per extension slot — that could not start until the first three had come back. Two waves, and the node serves only a few at a time, so a profile took seconds to assemble out of values that all live in the same record.

Values come back in the ORDER THE KEYS WERE ASKED FOR rather than as key=value pairs. An extension key is allowed to contain "=" (only commas and newlines are forbidden), so a pair encoding would have an ambiguous split; positional has none.

Line 0 is the record: owner, registered, expires, streak, frozen, and the grace period, which is global but is one more query the page would otherwise have to make on its own.

An empty return means the name is not registered. That is a real answer rather than an error: asking about a name nobody owns is the normal case on a profile URL somebody typed.
