What works

  • GF(256) field arithmetic (exp/log tables, mul, div, inv, pow)
  • Systematic RS encoding with parity layout [parity(16) || message(239)]
  • Syndrome computation and isValid() check

What doesn't work yet

  • Decoder (Berlekamp-Massey + Forney) — produces incorrect results for most error patterns

Build & Test

npm install
npm run build         # tsc → dist/
npm run test:full     # encoder + GF polynomial tests (PASS)
npm run test:decode   # decoder test (EXPECTED FAIL — decoder belum works)

Note: npm run test:full hanya menjalankan test yang PASS di versi ini. test:decode tersedia terpisah untuk debugging — akan FAIL karena decoder belum selesai.
