Bit-le

Can you crack the bitting?
Bit-le is a daily logic puzzle inspired by the world of locksmithing, keys and lock depths.
Your challenge is simple: discover the secret six-cut bitting in six attempts or fewer.
Each guess gives you clues:
BRASS means the depth is correct and in the correct chamber.
NICKEL means that depth exists in the solution, but belongs in another chamber.
GREY means the depth isn't part of the solution.
Use the clues, eliminate possibilities and work your way towards the correct bitting.
But there's another catch. Your bitting must obey the Maximum Adjacent Cut Specification (MACS). Bit-le uses a MACS value of 7, so adjacent cuts cannot differ by more than seven depths. Invalid combinations won't cost you an attempt, but you'll need to correct them before continuing.
