 7// Local assertion helpers.

 9// We deliberately avoid gno.land/p/nt/uassert here: when this realm is compiled
10// as an EXTERNAL package (outside the gno examples module) the working-tree copy
11// of uassert/v0 fails to preprocess with the pinned gno binary. These helpers
12// depend only on the standard testing package.
13//
14// GNS mutations PANIC with stable error values (see the error_* set) to revert
15// state, per gno semantics. A recover() inside this same realm package cannot
16// catch a crossing-boundary abort (only a pure p/ package frame can). Rejection
17// invariants are therefore unit-tested against the internal, non-crossing
18// helpers that produce the errors (authorize, priceFor, available, ...), and a
19// few end-to-end abort behaviours are covered by filetests.
