Canonical pair turn2->turn3: the complete block set, the three heap payloads no
previous capture could read (route [272], list-10 [1728], the 24-byte Population
body), the three AI client seeds, and both output autosaves -- byte-identical to the
published oracle AND to this lane's own hooks=off control, so the stream and the save
come from the same run and the instrument did not change the turn it recorded.
Creation turn turn1->turn2: three runs. Pinning the AI client seeds to the values an
earlier run observed made a DIFFERENT process reproduce that run's block -- including
the research pick that varies -- and its autosave byte for byte. The workload three
lanes could not reproduce is reproducible given the seeds.
Two corrections to lane L4's list-23 reading (no trailing int; the body is not
turn-dependent) and one to my own list-5 record, the latter found by lane RB while
consuming this capture.
Format: JSON (raw words are ground truth, decoded is a typing) plus lane RB's own .tcb
grammar with the heap payloads filled in, so RB's reader consumes it unchanged.
