## Why it matters

Viral framing (~25k views) of Colkitt's results; the model attribution (GPT-6.1 Astra) is the poster's claim, while Colkitt's repository credits OpenAI Codex.

## Summary

Quote post of @0xdoug's κ = 2^-59 announcement, posted 20:42 UTC. The claim that "6.1 Astra" was running in a loop is bubbleboi's; the repository README says only that the work was "performed with assistance from OpenAI Codex" and names no model.
