γ every sender emits, and the ceiling on any detection γ.

Circuit-pinned: out_clue_bits is a public input constrained by ClueCheck, so raising it is a @lelantos-org/circuits change.

A clue packs c_1..c_γ into a 16-bit prefix with the unused bits zero (clueBitsToPrefix), while fmdTest requires bit_i ⊕ c_i = 1 for every i in the detection key. A longer detection key therefore tests trailing bits against zero padding, each passing only when the recipient's own shared bit is 1, so a genuine note survives with probability 2^-(γ_detect - γ_sender).
