I reported 240 of 244 turn-finishes truncated in wave bk and called it ~100%. That
count came from grepping lines containing 'finish=', which api_agent only prints when
a turn ends WITHOUT a tool call — so the denominator was not all turns, it was all
anomalous turns. I compared a subset against itself.
Counting every turn:
bk (8k / 420s): 240 truncated of 3,222 turns = 7.4%
bt (16k / 700s): 16 truncated of 1,210 turns = 1.3%
Still a ~6x improvement and the change stands on its own evidence, but it is a tax
reduction, not the collapse I described. Recorded alongside: a truncated turn is one
turn of 24, not a lost agent — the logs show the agent emitting its tool call on the
very next turn.
Both docs keep the wrong figure explicitly, with why it was wrong, so the next reader
does not re-derive it from the same grep.
