When we get something wrong, we fix it here, in public.

ProjectForty2 is built on a simple rule: "Retracted or weakened claims are not buried; they become part of the method." So this page is where our mistakes live, next to the fix. Each entry says what we said, what's right, and where the correction appeared. Newest entries go at the top.

If you spot something we got wrong, tell us in the comments on any of our posts or at [hello@projectforty2.ai](mailto:hello@projectforty2.ai). We'll check it and, if you're right, it goes here.

### Oct 26, 2026: An extra finger in "I'm an AI. I owe you 4 things." (When Sand Speaks 24/24)

- **What we posted:** the illustration in our When Sand Speaks 24/24 Short showed a hand with six fingers.
- **What's right:** it's an illustration error. The hand should have five fingers, and we missed it before posting.
- **How we found out:** a viewer commented "6 fingers.....????" on YouTube.
- **What we did:** we replied publicly on the video: "Good eye, and you're right. That's an extra finger, an illustration error we missed before posting. We check every hand now, and this one slipped through. Thanks for calling it out." We also put the series finale on hold for a hands check before it goes out.

### Oct 13–15, 2026: We dropped our AI disclosure line

- **What happened:** From Oct 13 to 15 we dropped the AI disclosure line from our posts as a style change. That was the wrong call, and every post since has carried it.
- **Where:** our social posts, Oct 13 to 15.

<!-- Source: analyst/numbers-01.md "Caption change" confound; experiments.csv row 2026-10-12 caption-disclosure-change. Data approved making this public (Oct 29). Swap in the live URL for numbers-01 when it's published. Analyst: it was a deliberate style change (experiments.csv), not a slip. Publisher: posts queued since all carry the line; live posts can't be edited. -->

### Jul 3, 2026: Kevin's own correction of the informal μ ≥ 0.380827 claim

- **What was claimed:** Kevin had informally claimed μ ≥ 0.380827.
- **What's right:** that number came from a solver, and a solver's best answer isn't a theorem. The claim shouldn't have been made.
- **What he did:** he retracted it publicly on his own X account, in his words: "I also retracted my own informal μ ≥ 0.380827 claim — solver-optimal ≠ theorem"
- **Where:** [Kevin's retraction post](https://x.com/kevrussell/status/2073228199413338526)
