The output used to move after the small model's warmup had linked the
warp to its address, which needed the warp to link again by dropping a
private tinygrad cached property. Had that ever stopped working, the
small model's own warp would have kept writing the freed memory.
modeld now asks the adapter's coherent_warp() (Jetlink's make_coherent
with Jetlink on, off legacy9d) and load_verified_model moves the small
model's warp output before warmup(), as Jetlink's own warp moves its
output before its first call. CatalogWarp only reads the answer
(warp_copied): sent from where it is, or copied out, chosen once.
cable_connected() is true for any host on the USB-C port. With a Chestnut pick downloaded and Jetlink on, every drive waited 10 s for a chestnut, raised Big Model Failed and left Jetlink unattached. The cable now counts only with Jetlink off.
StarPilotAdapter subclasses jetlink's Stock: StarPilot's param names, the
AOL engagement rule, the model root and a CatalogModelState history reset
that keeps its JIT buffers. jetlinkd runs jetlink's owner as it is, modeld
calls the hooks, and Galaxy and analytics read jetlink's runtime record in
place of JetlinkRuntime.
- no big-model slot or catalog keys: jetlink provisions its default model
- jetlink restores the owner's tuning itself; the port draw stays cut with
a host plugged in
- the Jetson is asked to power off on DoShutdown only, capped at 30 s
