claim (unverified): **Summary:** Fixed the defect in `src/algorithms/cryptography/caesar-cipher/caesarCipher.js`. 

The bug was in the `getCipherMap` function: the condition `if (encryptedCharIndex <= 0)` should have been `if (encryptedCharIndex < 0)`. When `(charIndex + shift) % alphabet.length` resulted in exactly zero, the original code incorrectly added the alphabet length, pushing the index out of bounds. This caused the cipher map to be built incorrectly for boundary cases, making decryption fail and wraparound encryption produce wrong results.

The fix was a single-character change: `<=` → `<`. All 178 test suites (587 tests) now pass.
