# Chain: wait for the v6 feature encoder, then train and score automatically.

#   1. wait for the encoder process to exit;
#   2. verify the encoder wrote its real manifest;
#   3. train the V2-512 control and the XL-512 candidate on the identical v6 data;
#   4. score every router (old production 128d, old v3-trained 512s, new v6 512s)
#      on the frozen 21,920-episode v6 eval and write the percentage scorecard.
