1. Read the prior as an object. 0.1 to 1.25 is a width of 1.15 and a ratio of 12.5x. The base default in the same source tree is 0.5 to 1.25, a ratio of 2.5x. Widening the lower edge alone multiplies the ratio by 5x. Print all of it, and print the three other axes the same configuration widens.
2. Spend the band in newtons. For a load held between two fingers, the normal force that just holds it is m g over n mu. Evaluate it at the low edge, the mean and the high edge. The span in force is exactly the 12.5x span in the band.
3. Compare against published practice. German gripper practice designs at mu = 0.1 with a safety factor of 2, which is an effective coefficient of 0.05. Work out the ratio against designing at the band mean.
4. Spend the band in slip probability. A uniform prior with no estimate means a policy trained to hold at the band mean slips whenever the real surface sits below it, which for a uniform band is half the time. Confirm it by sampling, then build the trade table: what clamp force each slip probability costs.
5. Audit the units. List every friction quantity the review located across five regions, with the unit each one is stated in. Count how many are a dimensionless surface coefficient identified with an uncertainty band. The count is the finding.
