"Do an amend, fixed a typo."
a3dc16f — renamed sho11_samovar_top_v1_user.png → shot11_samovar_top_v1_user.png (missing t).
"shot11_samovar_top_v2_user.png — there was a mistake in this shot. Can you find the last v1 generation and repeat the video with this ref?"
Found the previous run in generations.log.jsonl:
prompt: "@Image1 as first frame. Animate: white steam rises and curls upward
from under the samovar's lid, escaping through the gap between the
lid and the body..."

Regenerated with the same prompt, new ref:
generations.log.jsonl as a decisions log: convenient to find the previous prompt via grep and repeat exactly with a new ref. The rule "same prompt against an updated ref" gives predictable results.shot11_samovar_top_v2 replaced v1 in the utility list.
