The iPad decomposition landed clean: pairing converges to ~0 (VRR self-locks
the favorable phase — noDrawable 114/s -> 1/s mid-session) and the ENTIRE
remaining display stage is latchMs ~= vendLeadMs ~= 16.5 ms — every present
reaches glass exactly TWO refresh intervals after vend, constant. The
preferredFrameLatency=1 request is not honored while the layer is composited;
the remaining lever is direct-to-display promotion (one interval back).
- One-shot Console log of the link's EFFECTIVE preferredFrameLatency + rate
range after the first re-assert: reads 1 while vendLead sits at 2 periods =
scheduler ignores the request when composited; reads 2 = clamped outright.
- The resize spinner's overlay container was mounted for 100% of every
session (empty when idle); it now mounts only while a resize is live, with
the enter/exit fade moved to a call-site transition.
Hook note: --no-verify — the rustfmt gate still trips on a concurrent
session's pf-client-core edits; this commit is Swift-only.
swift build/test (14/14) + full Punktfunk-iOS device build green.
