In the active files, that natural compound had been replaced with the toxic butyl-paraben derivative.

The changes had been made in small, calculated increments over the past three weeks.

It was a slow, deliberate poisoning of the product line, designed to bypass the automated quality alerts.

If the product went to shelves, consumers would experience severe kidney damage within weeks.

And my digital signature was stamped on every single approval form.

The terminal screen cast a pale blue light over my hands as I printed out the entire alteration log.

The laser printer in the corner whirred to life, spitting out warm sheets of paper.

I gathered the pages, my palms absorbing the heat from the fresh ink.

I slid the documents into a thick, manila folder.

Next, I walked to the heavy metal filing cabinet in the corner of the lab.

I unlocked it with my key and pulled out my physical laboratory notebook.

This notebook contained my handwritten daily entries, signed and dated by my supervisor.

This was my ultimate protection.

It proved that I had never authorized, or even tested, the toxic compound.
