- objc.sx, objc_block.sx (from std/) + sdl3/opengl/raylib/stb/stb_truetype/ wasm vendor bindings (from modules/ root) -> modules/ffi/ - std/uikit.sx deleted: platform/uikit.sx already declares UIApplicationMain and imports objc; '#framework "UIKit"' cannot live in a file imported on macOS targets (unconditional link directive, UIKit is iOS-only), so the three iOS-only examples carry the 3-line glue inline. 1607/1608/1616 also un-rotted (dead ns_string -> 'xx "..."' Into conversions, callconv(.c) msgSend fn-ptrs) — all three build for ios-sim/ios again. - math/math.sx -> math/scalar.sx; one spelling '#import "modules/math"' everywhere (4 pinned IR snapshots regenerated: dir import adds Vec2/Mat4 to the type tables). - compiler.sx -> build.sx (imports, CLAUDE.md bundling table, specs.md). - testpkg/ + test_c.sx -> tests/fixtures/ (resolve CWD-relative from repo root, same as vendors/). - library-internal imports use full modules/... paths (std.sx tail, platform/bundle.sx, fixtures).

// ffi-objc-arc-00b — multi-instance allocator threading.
|
|
//
|
|
// Verifies that EACH sx-defined-class instance captures its own
|
|
// allocator and round-trips through it. Catches bugs where:
|
|
// - the captured allocator is shared across instances (one global
|
|
// slot instead of per-instance).
|
|
// - alloc captures the wrong allocator on the 2nd+ instance.
|
|
// - dealloc reads garbage if state[0] is overwritten between
|
|
// instances.
|
|
//
|
|
// Three instances → three alloc events → three dealloc events. The
|
|
// tracker observes exactly +3 / +3 deltas.
