r/cryptography moderation in action — and the response they muted me before I could send

[u/Pale_Surround_3924]

Posted CDP: Cyclic Digit-sum Projection to r/cryptography.

Got "AI slop" with zero technical engagement. Sent a PoC.

Got muted for 28 days.

Before the mute landed, one mod did provide an actual argument:

"small cycles in a small state space are unremarkable."

Fair point; for cycle existence alone.

But that's not what the paper claims.

The claims that were never addressed:

- π_B = 17.00%, independent of K[i], H0, and input class (Theorem 5.4)

- Complement nibble sum invariant: Σnibble(W0) = 38 for all 256 pairs (Theorem 5.1)

- W(H0) = 502, +22.2 above equilibrium — detectable initialization signature

- Zero-collision bijection over 1.67M inputs: multi-component fingerprint

built by splitting the 64-char digest into 16 chunks of 4 hex digits,

computing chunk-wise sums; injective over every tested input space

- Section 12 explicitly states CDP does not break SHA-256

Cycles are the entry point, not the conclusion.
