Note: This is a toy project and far from cryptographically safe, better don't use it in production.

This project lets you fingerprint your files using LLM-generated poems instead of hard-to-remember checksums. It computes a `BLAKE3`

hash of the passed file, and based on that injects entropy in both the LLM sampler as well as the prompt itself. The output is a five-line poem representing a fingerprint of your file.

```
In twilight's hush, a phantom sloped
Across the meadow's trembling rim
A fleeting yodel echoed clear
As moonlight danced and stars drew near
In darkness's silence, all was grim
In a lovely abode I rest my head
Behind an ancient obelisk I softly tread
In the still of night a player draws near
She shakes her tambourine and whispers sweet cheer
The stars above twinkle with gentle delight
```
