# Second Loop — Project hub

Landing page for the three demo Spaces of the Second Loop project. Each linked
Space is fully static (no model loaded); every number is a verbatim output of the
live experimental run.

- **Part 1 — Scar-Survival** — a memorized LLM error, corrected: how durable is the fix?
  · [Space](https://huggingface.co/spaces/Laborator/scar-survival)
  · [GitHub](https://github.com/SergheiBrinza/scar-survival)
- **Part 2 — External Grounding** — lifting self-correction 50% → 100% under a noisy notebook
  · [Space](https://huggingface.co/spaces/Laborator/external-grounding)
  · [GitHub](https://github.com/SergheiBrinza/external-grounding)
- **Part 3 — Thin Channel** — how rarely external truth can arrive before calibration collapses
