// A BARE generic struct INSTANCE method (`x.tag()`) must dispatch to the method
// authored alongside the instance's layout — the single bare-VISIBLE author —
// NOT the global last-wins `fn_ast_map["Box.tag"]`, which a NON-visible
// 2-flat-hop same-name template's method can win.
//
// `b.sx` declares a one-field `Box($T)` (size 8) whose `tag` returns `self.x+8`,
// and itself flat-imports `c.sx`, whose two-field `Box($T)` (size 16) declares a
// `tag` returning `self.x+16`. This file flat-imports ONLY `b.sx`, so `b.Box` is
// one flat hop away (visible) and `c.Box` is two hops (NOT bare-visible).
//
// Regression (Phase E4 finding #1, instance-method site): the static head
// `Box(i64).make(7)` already selected `b.Box` for the layout (size 8), but the
// instance method `x.tag()` resolved by bare template name in `fn_ast_map`, so it
// ran `c.Box.tag` (returning 7+16=23) on the b instance. Fail-before printed
// `size=8 tag=23`; with body-author ≡ layout-author it runs b's `tag` (7+8=15).
