Store forwarding crosses an intervening may-alias write · case 02

Store forwarding crosses an intervening may-alias write.

Member previewVariant 2 · 3 implementations · 7 checks per implementation

Case contract

Return candidate value if every intervening write is proven disjoint; otherwise return None meaning retain the load. Alias facts are no, may, or must.

Why this case matters

A deterministic miniature compiler-pass model; inputs are explicit IR facts, not a production compiler.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
