{"ts":"2026-05-21T17:40:33+00:00","type":"decision","status":"ok","note":"Mimir live camera ingest should talk directly to drivers through IMimirVideoCaptureDriver: LeapUVC/libusb, LeapC images, Media Foundation, DirectShow, or GPU shared textures."}

The repo's live surface is C# Mimir.Runtime, Mimir.App, native reservoir, PowerShell bridge utilities, Aquarium, and Faust/native DSP."}

At 640x480 requested 60 Hz they delivered 58.69 fps and 57.09 fps. Leap remains unmeasured in raw UVC/KS mode."}
{"ts":"2026-05-21T20:05:00+00:00","type":"verification","status":"ok","note":"Native LeapUVC Kernel Streaming probe measured VID_F182 through usbvideo.sys without Media Foundation, DirectShow, OpenCV, or frame processing. Advertised 640x240 YUY2 stereo IR mode is 115 fps; the minimal one-buffer blocking KS read loop delivered 415 frames in 5.003s (82.95 fps). 640x120 delivered 155.40 fps against a 214 fps advertised mode. Next driver cut needs queued KS/AVStream streaming, or an explicit WinUSB/libusb UVC driver rebind decision if usbvideo.sys remains the bottleneck."}
{"ts":"2026-05-21T20:25:00+00:00","type":"verification","status":"ok","note":"LeapUVC KS probe now keeps eight asynchronous NtDeviceIoControlFile reads queued. The path reports async=yes but cadence stays effectively unchanged: 640x240 YUY2 delivered 415 frames in 5.004s (82.93 fps), and 640x120 delivered 777 frames in 5.000s (155.39 fps). The limiting factor is not simply an empty user-mode read queue."}
{"ts":"2026-05-21T20:55:00+00:00","type":"verification","status":"ok","note":"LeapUVC KS control sweep showed the short-window 83 fps result was mostly startup drag. With two seconds of warm-up discarded and eight queued async KS reads, 640x240 YUY2 delivered about 110.7 fps against 115 fps advertised; 640x120 YUY2 delivered 1030 frames in 5.003s (205.87 fps) against 214 fps advertised. Exposure, gamma, HDR/LED, gain, and dark-frame controls are reachable through KS; digital gain=0 and the old FPS-ratio selector are rejected with ERROR_INVALID_PARAMETER."}
{"ts":"2026-05-21T21:25:00+00:00","type":"verification","status":"ok","note":"Razer Kiyo direct KS probe measured VID_1532 PID_0E03 and PID_0E05 camera interfaces with eight queued async reads and two-second warm-up discard. Plain Kiyo is exposure-limited by default: 1920x1080 MJPG reaches 30.27 fps with manual exposure -9/-10, and 1280x720 MJPG reaches 51.51 fps after manual exposure/gain sweep against 60 fps advertised. Kiyo Pro advertises 60 fps at 1280x720 and 1920x1080 MJPG, but the current KS path delivers only about 25 fps regardless of manual exposure; it needs separate control/driver investigation before high-cadence use."}
{"ts":"2026-05-21T21:55:00+00:00","type":"verification","status":"ok","note":"Online Kiyo Pro research found matching trouble reports: Razer documents 1080p60/720p60, HDR can reduce frame rate, anti-flicker/powerline can interact with frame rate, and Microsoft maps low-light compensation to AUTO_EXPOSURE_PRIORITY, which can vary frame rate. Local KS follow-up found Kiyo Pro reports low-light priority=1 and powerline=50Hz. Setting low-light priority to 0 did not improve cadence; setting powerline to 60Hz moved 720p/1080p MJPG only from about 25 fps to about 29 fps. Standard KS controls are not enough; next step is compare Synapse/OBS and inspect vendor/extension controls or firmware state."}
{"ts":"2026-05-21T22:15:00+00:00","type":"verification","status":"ok","note":"Kiyo Pro HDR-off test added KSPROPERTY_CAMERACONTROL_EXTENDED_VIDEOHDR get/set with filter-scope and pin-0 extended-property headers. The camera returns Element not found for standard extended Video HDR, and setting HDR off does not change cadence: 720p/1080p MJPG remain about 25 fps. HDR may still be controlled through Razer/Synapse, but not via the standard Windows extended Video HDR KS property on this path."}

Stronger finding: the local Kiyo Pro is behind a Genesys Logic VID_05E3&PID_0610 hub at USB speed 2 / bcdUSB 0x0210, so it is on a high-speed USB 2.x path rather than SuperSpeed USB 3.x. Verify/move bus topology before mutating unknown vendor controls."}

Windows still reports USB speed enum 2 (UsbHighSpeed, not UsbSuperSpeed). Baseline cadence remains locked around 25 fps across all tested 720p/1080p formats: YUY2 24.96/24.98, MJPG 25.20/25.03, H264 25.19/25.01, NV12 25.07/25.16.
