Shipping a gated adapter was ad-hoc ssh + rsync three times running. This makes
it one reproducible command for the rest of the line (Faulkner, Morrison,
Chandler are next).
The sha verification is the point, not decoration. "Copied the adapter" is a
claim with no honest form but a read-back, and a truncated or half-written
adapter loads without complaint and serves a subtly different voice. The digest
is taken at the source on gx10, after the local hop, and at the destination on
fv-ml1; any mismatch aborts before the seat is ever told the file exists.
It ships only adapter_config.json and adapter_model.safetensors. A checkpoint
dir also holds optimizer state and RNG, which are large, useless to the seat,
and would make the destination digest disagree with any future re-ship.
It deliberately does NOT edit the compose or restart the seat. Registering an
adapter is a reviewed edit to stacks/voices-seat/compose.yaml, because that file
is where the gate verdict and its caveats get written down for whoever reads it
next -- that is a feature of the current process, not friction to automate away.
Verified against the already-shipped lv-hemingway: the live adapter on fv-ml1 is
byte-identical to gx10's checkpoint-850 on both files, which confirms the file
list and the convention this script encodes.
