Six remaining dispatch clusters migrated in one pass:
- `uikit_setup_renderbuffer`: `renderbufferStorage:fromDrawable:` (BOOL).
- `uikit_present_renderbuffer`: `presentRenderbuffer:` (BOOL, every frame).
- `uikit_gl_view_tick`: `targetTimestamp` and `duration` reads (f64,
every frame — three call sites total across the keyboard-anim path
and the frame-closure path).
- `uikit_compute_layer_pixel_size`: `bounds` (CGRect HFA).
- `uikit_touch_location`: `locationInView:` (CGPoint HFA — first
standalone `#objc_call(CGPoint)` exercise, structurally identical to
the 2×f64 NSPoint already verified by ffi-objc-call-05).
- `uikit_first_touch`: `anyObject` (*void).
Net -15 lines. uikit.sx is now 839 lines — Phase 1D started at 937,
so this is -98 cumulative across the migration. Zero `xx objc_msgSend`
typed casts left in the file.
iOS-sim chess regression smoke: launched chess, tapped a black pawn
through the Simulator window, watched the move (d7→d5) play, then a
second tap played d5→d4. The render loop, touch handlers, layout
math, and the BOOL-returning EAGL presentation calls are all on the
exercised path, so this is the strongest runtime verification any
Phase 1D commit has had so far.
22 `sel_registerName` calls remain in the file, all legitimate:
- `class_addMethod` IMP registrations (runtime class build-out).
- SEL-as-arg to dispatch selectors that take a SEL value
(`addObserver:selector:name:object:`,
`displayLinkWithTarget:selector:`). A future `#objc_selector("foo")`
literal would replace these, but it's not part of Phase 1.
