kld died: 'cannot read --kld-corpus /data/kld.jsonl' — KLD_MOUNT was
referenced but never defined, so the corpus/ref-dir mounts silently
expanded to nothing. Add them (nested order: after the /data mount).
feat(convert-swift15-w4dn8): final recipe convert on 1.0.13
Convert with the SERVING pin so the .rad crosses no version boundary;
only the Gram files cross (RADGRAM2 magic, gram.r%d.%s.bin naming and
calib_gram/calib_resolve/calib_stem are byte-identical between the
1.0.13 and 1.2.0 libquant). Host-backend run: prod can stay up.
Gates: grams present (>=48), bf16 container deleted, disk floor,
rad-info gptq receipt, size floor 126000 MiB.
