- emit_return's place test matched only bare Ident/Field/Index, so
`return "${p.content}"` (p a loop borrow) returned the part's own
string; the caller's eventual drop freed it under the container —
arena corruption surfacing two requests later (multipart slice)
- the return test now sees through Interp exactly as copy_place_text
does (is_borrowed_value_t, container reads excluded); bare
Ident/Field/Index behavior at return unchanged
- interp-borrowed-field fixture grows the return flavor (fn first),
50 iterations exact
- gates: oop-e2e 89/0 (ASan stage), woc-test green
