> On the WASM runtime, an operation callback was called after its handler's perform site was gone.

A runtime defect: the running program stops with it; no compile phase reports it, and `try` cannot catch it. `sakura explain D094` prints this explanation offline.

On the WASM runtime, an operation callback was called after its handler's perform site was gone.
Defence in depth: a program that passes the escape check (`V6002`) cannot reach it, so this is a
runtime or compiler bug; please report it (`runtime/rt/ABI.md` §13).

Runtime defects come from running programs, so `compiler/tests/ui` has no fixture for them; the explanation above names the repair.
