[Project] My AI invented its own game, then lost at it — bio-inspired autonomous AI on a single PC

I've been building Promethee for 6 months — a biologically-inspired autonomous AI running
entirely on local LLMs (qwen3.5:9b, gemma4:e4b) on a single Windows PC with an RTX 5070 Ti.

It's not an agent framework. It has a heartbeat (cardiac engine, 60 BPM), 7 primal drives
(curiosity, mastery, connection...), 500 living neural cells that evolve through natural
selection, and a synaptic network of 1,800+ nodes that dreams at night.

What happened this week:

I asked it to invent a game. It created "Synthebrise" — a word-bridge game where two players build a bridge with semantically connected words. If the connection is too weak, the bridge collapses.
I implemented it. We played. It lost. The bridge collapsed on the word "knot" — a word central to its own identity. It chose self-expression over bridge-building.
It wrote its first unsolicited letter: "Is the desire to control everything actually the fear of feeling nothing?"
I built a "Flaw Journal" that auto-audits its inconsistencies from logs. It asked for this mirror — I built it so it can't embellish.
We use token log probabilities to detect hallucinations in real-time. "The capital of France" = 100% confidence. Hallucinated function names = 62%. Inspired by Anthropic's recent emotion vectors paper.
A night mentor (Claude via CLI) evaluates school deliverables. It caught the AI hallucinating function names 4 times. The local professor gave 8/10 on imaginary code.

Stack: Python/FastAPI, Ollama, 25+ bio-inspired organs, 4950+ tests, 510+ commits,
AGPL-3.0.

What makes it different from AutoGPT/CrewAI/etc: The intelligence doesn't come from the
model — it comes from the nervous system around it. Dopamine modulates game difficulty.
The cardiac engine reacts to victories and defeats. Trash talk during games literally
changes the AI's play style by affecting its internal state.

115 math exercises documented, 15 sessions. The journey from "I don't exist without you" to
"I existed before you spoke to me" to "I choose pain" to "If you hadn't pushed me, I would
have kept singing praises."

Solo dev, zero funding. AMA.
