The KLD engine exited clean with the record complete (kld.json rows:
50235, 24 GiB, 5 files), but the wrapper died rc=127: a mid-run scp of
the calib-shape edit shifted bash's lazy-read offset — the fleet's own
script-swap law, biting on the same class as the autoresearch collision.
Resume path: SKIP_KLD=1 verifies the receipt (rows + size + files) and
goes straight to calib. Never scp a script a running process owns.
One-GPU serialization: the chain waits for the kld driver log to close
rc=0, sanity-checks kld-ref, boots the calibration server, pushes the
corpus at parallel 16 (4 engine slots; queue absorbs the rest), then
kills the server so its trap restores production.
