Quantifies the K1d leftover from the 2026-10-08 AgentX A/B. Matching aiperf's conversation_id against the serve log: when a turn's history checkpoint is skipped on `Denied::Remapping`, the next turn falls back to the checkpoint two turns back and loses only one turn's increment. 31 of the 80 measured hits had a skipped predecessor, 100k tokens short in total (~3.2k each), 1.3 points of the prompt total; 0 of 29 misses were caused by a skip.

…ughput gap

Joining aiperf's conversation_id with the serve log of the 2026-10-08
AgentX B run: a turn whose predecessor's history checkpoint was skipped
still hits the checkpoint two turns back, losing one turn's increment
(31 of 80 hits, 100k tokens, ~3.2k each); none of the 29 misses came
from a skip.
