GetVibrationDeviceHandles used routed haptics availability to decide whether
handles existed. Games that cache this answer at startup could retain an empty
answer after a controller connected. Return handles for a connected npad style
when rumble is enabled and an output sink is installed; check routed outputs
when values are sent, keeping the existing permission and lifecycle behavior.
Include the PR's rumble diagnostics, count unroutable values individually in
mixed batches, and protect aggregate counters across game threads. Correct the
code comment to describe Unicorn Overlord's observed empty handles and zero
values without claiming restored physical rumble.
Add regressions for cached startup handles delivering a nonzero value after
routing, diagnostic totals and concurrent sends. Include HID in the existing
ThreadSanitizer target and record the mechanism in the service reference.
Checked with GAME=010069401ADB8000: full host suite, 73 HID checks, audio and HID
ThreadSanitizer checks, docs checks, Mac host build, and iOS compilation
(133 files). Physical rumble and iOS runtime remain untested. Broader tool
validation is incomplete because Capstone is missing and iconutil failed.
