Count Min Sketch Rehearsal API

Build a deterministic frequency sketch from explicit integer hash coefficients and positive updates.

Build a deterministic frequency sketch from explicit integer hash coefficients and positive updates. Width1..1024,depth1..16,validated prime2..65521,nonnegative keys through 1e9,positive update counts through 1e9,and at most 4096 updates/queries subject to shared input limits. Explicit a in1..prime-1 and b in0..prime-1; hash=((a*key+b) mod prime) mod width computed with BigInt. User-fixed hashes provide deterministic results, with no probabilistic error or cryptographic guarantee. Integer result fields use numbers through absolute999999999999 and exact decimal strings beyond that, so shared numerical display rounding cannot change integer results. Uses supplied non-sensitive data only. No live account access, automatic changes or certification. Calculation profile 1.0.0; approximate non-integer numeric outputs use twelve significant digits; representable safe integer numbers and declared decimal-string integers are preserved.
