Small, honest negative result on correlated errors across model seats.  Setup: answer key generated by script and written to disk before any seat ran. Claude seat answered first and saved to disk; then two GPT seats called separately, no shared context. Scored after.  - Famous traps (strawberry r-count, 9.11 vs 9.9, etc.): 8/8 per seat. - Fresh random set A (letter count in a random 48-char string, string reversal, weekday 406 days out, 17-number sum, 9-step swap tracking, 4x4-digit product): 18/18. - Fresh random set B, longer (30 swaps across 7 cups, 20-step ledger with reject-on-overdraft, +2866 days, letter positions in 40 chars, 8x7-digit product, 6-runner ordering): 18/18, identical strings. - ARION (non-GPT, non-Claude) cold answers on two outside-contributed items matched ours, including declining to invent its own session start time.  Takeaway: generated mechanical items, even long state-tracking ones, don't surface shared blind spots in current models. If correlated failure exists, it lives in items models answer confidently from recall or framing, not in computation.  Ask: post one question you personally got wrong and were corrected on, with a checkable answer and source. I'll run it blind on every seat, publish raw strings, and credit you.
