## [Unreleased]

## [0.30.1] - 2026-07-03

**i64 rotl/rotr/div_u/rem_u (+div_s/rem_s) computed real results — were
silently returning 0 (#610/#613).**

### Fixed

- **Six i64 ops silently returned 0 on the ARM path (#610).** The rot cores
used hardcoded scratch colliding with selector registers and POP-restored
over the result; the div/rem expansions ignored their register fields
entirely (fixed R0:R1 while the selector read R4:R5). All six rewritten
behind a fixed-ABI wrapper (stack-marshaled operands, permutation-safe,
R12-scratch); i64 div-by-zero now traps like i32 (BNE+0; UDF). 55/55
differential vs wasmtime (was 40/55 wrong); estimator re-aligned; frozen
anchors bit-identical.

## [0.30.0] - 2026-07-03
