Runtime augmentation of Hugging Face without modifying source – CMPSBL Demo

I experimented with adding a deterministic runtime layer to an existing codebase without modifying its source.

As a test case, I used Transformers from Hugging Face Transformers and took modeling_utils.py (v5.5.0) directly from the repo.

Instead of changing the file, I wrapped it in a secondary runtime layer and dropped it back into the stack under the original filename. The original code remains intact and executes normally.

With that layer active, I was able to add:

• input validation / interception (e.g., basic SQL/XSS detection)

• persistent state across calls

• a simple adaptive loop (escalates after repeated bad inputs)

The underlying model loading and inference behavior remains unchanged.

I’m not claiming this is novel in isolation (it uses familiar techniques like wrapping and runtime injection), but I’m interested in whether a constrained, deterministic “second layer” like this could be a practical way to add governance/observability to existing systems without modifying their source.

Curious how others would approach or critique this.
