Classify configured devices by keyboard and pointer capability so automatic keyboard capture leaves relative pointer devices with the display server. Run descriptor, grab, physical-state, and LED operations on one worker. Marshal normalized events through each display server's event loop and serialize ownership changes with per-lane barriers. Fall back whole lanes to native input when an evdev cohort cannot be owned, and retry missing or removed devices without disabling the rest. Handle report framing, SYN_DROPPED, high-resolution wheels, queue overflow, held-state cleanup, and guest-driven keyboard LEDs. Restore host LEDs and kernel grabs during teardown. Re-evaluate capture when the active input transport changes.
