window while another controller is active. Do not restore continuous inquiry
as a convenience feature; it causes gameplay latency.
A narrowly scoped exception now permits low-duty passive BLE discovery while
a ready solo Joy-Con 2 awaits a remembered opposite half. It requires free
physical capacity and no pending controller setup, accepts only remembered
opposite-half candidates, and stops when the pair completes. It neither
starts Classic inquiry nor opens new authentication. Lifecycle regressions
cover setup failure, capacity exhaustion, pairing-window transitions and
unrelated-controller isolation.
## Implementation principles

Joy-Con hardware, physical rumble feel, reconnect endurance and mixed-radio

Switch 2 native HD output now preserves decoded stereo frequency/amplitude

recorded zero drops. Deliberate three-subframe saturation at 125.11 Hz
discarded/superseded 69 output-stage commands out of 128 host updates and
recovered to a clean stop. No mixed-radio lossless claim is made.

Paired Joy-Con 2 stereo/subframe patterns produced 394 physical dispatches
from 197 host requests without queue drops; the user confirmed both sides.
Normal GATT-client busy responses now retain queued output instead of
disconnecting the controller.
Two Switch 2 BLE links plus Classic now select 30 ms Switch 2 connection
intervals automatically; other topologies retain 7.5 ms. This trades Switch 2
delivery latency for Classic airtime without changing HD encoding or bonds.
Physical DualSense power-off/reconnect verified both interval transitions
without losing the Joy-Con links. A 30-second production mixed-rumble run
kept native DualSense streaming, with no send failures or ingress drops,
14 Joy-Con output-stage discards and nine PCM skips. It is not lossless.
Verification is now 289 passing tests and all five firmware builds. All
40 pre-existing profiles, metadata and adapter configuration remain unchanged;
the current inventory contains 56 profiles across seven identities. Temporary
measurement hooks were removed, and the final production image passed another
simultaneous-rumble exercise after normal controller reconnect. See the
[native HD contract and measurements](README.md#switch-2-native-hd-rumble).
