Not applicable (this is a logical issue, not dependency-related)

Expected behavior

All methods (compress, decompress, and coordinate_map) should handle missing or invalid values consistently.

Either:

All methods raise exceptions (e.g., KeyError, ValueError) for invalid inputs, or

All methods return a defined sentinel value (e.g., -1 or None) to indicate failure.

The chosen behavior should be clearly documented and predictable.

There should be no mix of silent failures and exceptions.

Actual behavior

he methods currently behave inconsistently when given invalid or missing inputs:

compress(80) → returns -1 (silent failure)

coordinate_map[80] → raises KeyError (exception)

decompress(5) → returns -1 (silent failure)

This inconsistent mix of return values and exceptions makes debugging difficult and can lead to unexpected runtime behavior.
