+short_description: Durable correction of memorized LLM errors — hub
+---
+
+# 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), all numbers are exact
+outputs of the live experimental runs.
+
+- **Part 1 — Scar-Survival** — durable correction of memorized errors
+  in a frozen LLM
+- **Part 2 — External Grounding** — defending the correction notebook
+  from polluted memory
+- **Part 3 — Thin Channel** — how rarely external truth can arrive
+  before calibration collapses
+
+GitHub repositories are linked on every card.
