Handle edge cases in filtering

**Description**
Currently lib lacks proper compression support.

**Proposed solution**
Add configurable compression with sensible defaults.

**Priority**: Low/Medium

Start by locating the filtering implementation under lib and tracing how inputs are read and processed. Define how configurable compression and its defaults should apply to the filtering path, then verify the relevant edge cases and configuration behavior with the project’s existing checks.
