- Per-frame timing on the Mac's clock (capture, encode, network, decode, draw), viewer clock sync and reports, input echo, /stats and a HUD. - scripts/macview-bench.py: repeatable runs on the real Frame, a shaping relay (no sudo), interleaved A/B between agent settings; results in bench/results/. - Adaptive controller: ack-based send gate with jitter-aware slack, AIMD bitrate that knows when a stream is app-limited, fps then size tiers. On a 50->3->50 Mbit/s step, scroll p95 went from 4.7 s to 72 ms; no cost on a clean link. - Separate mode: real AppKit event loop (HiDPI and NSScreen now work), cropped capture for fixed-size windows, windows kept on their display, graceful quit restores windows; stop/start races fixed. - Encoder timeline clamp (no oversized frame after a pause). - Frame Control shows each live stream's fps, delay, bitrate and tier. Reviewed by GPT-6 Astra xhigh (read-only), 7 rounds; findings fixed. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

<!-- Control experiment, run on the Frame itself: how often does Chromium on
|
|
gamescope put a canvas animation on screen, with no network or decoding
|
|
involved? Draws every animation frame for ?s= seconds and writes the
|
|
frame-gap histogram per second into the title, where xprop can read it. -->
