The J815 ADT (macOS 27.0) puts the fingerprint sensor on spi2 at 0x3a5108000, 8 MHz, chip select 0. Its power is NUB GPIO 36 and its data-ready line is AP GPIO 200. The sensor is the generation J713 and J714s use. The SEP is a pre-booted iop-sep,ascwrap-v6 behind a t8110 DART with the BIT(40) input aperture, the same SoC side as T8132 and T6050. Use T8132's profile with the sensor controller moved, and select it only for J815: the J813's sensor bus has not been checked. Tested on J815: the SEP driver binds with the T8142/J815 profile, its 12 endpoints come up, the keystore opens and the hwrng registers. The sensor binds on spi2 at 8 MHz and comes up in about 40 ms. With xart_guard=1 (the T8142 default) fingerprints enrol (36/36 stages, both Catacomb records saved, no guard refusals), sudo matches with the finger, and the enrolment is restored after a reboot. macOS Touch ID keeps working after the Linux enrolments.

There was a problem hiding this comment.
Codex (GPT-6.1 Sol), reviewing on @DjDeveloperr’s behalf.
No blocking source findings in the reviewed net change. J815 SEP admission requires the explicit J815+T8142 compatible pair and inherits the established profile without changing the xART/identity geometry. Owner Touch ID evidence supports board admission; shared-state/provisioning/consent protections remain intact.
Hosted contributor workflow approvals were unblocked; source approval does not waive any pending CI/native build or dependency gate. Hardware reports are attributed to their authors, not new tests by this thread. No images/default-loader/hardware changes were performed.

SEP profile for J815, selected only for J815: T8132's profile with the sensor controller moved to spi2 (0x3a5108000, 8 MHz, CS0), sensor power on NUB GPIO 36, data-ready on AP GPIO 200 (J815 ADT, macOS 27.0). The SEP side (pre-booted
iop-sep,ascwrap-v6, t8110 DART with the BIT(40) aperture) matches T8132/T6050.Tested on J815: the SEP binds, 12 endpoints, keystore, hwrng; sensor bring-up in ~40 ms; with
xart_guard=1(the T8142 default) fingerprints enrol (36/36, both Catacomb records saved, 0 guard refusals),sudomatches with the finger, and the enrolment is restored after a reboot. macOS Touch ID still works after the Linux enrolments.The matching DT nodes are in #1532 (J815 device tree); the sensor-reset fix is #1536. J813's sensor bus was not checked, so J813 is left alone.
Part of the J815 (MacBook Air 15-inch, M5, T8142) bring-up: board results are summarised in discussion #135. Tested on a J815 with a macOS 27.0 stub (firmware 27.0) through aura Stage 2.
