Chp Cleanup And Index

# CHP Cleanup & Index Generation Prompt

You are working inside the `D:\EXPERIMENTS\context-hacking\` project.

Your job is to do three things in order:
1. Rename every completed experiment directory with the correct prefix
2. Standardize file names inside each experiment
3. Write a clean `experiments/EXPERIMENT_INDEX.json` the UI can consume

Do NOT modify any scientific content — source files, frozen constants, test files,
figures, or REPORT.md. Only rename directories and files. Do NOT touch staged or
superseded experiments.

## STEP 1 — Understand the Evidence Standards

Every experiment gets one of three prefixes based on its evidence standard:

| Prefix | Standard  | Criteria |
|--------|-----------|----------|
| `cat-` | Catalog   | Single-pass. Errors were pre-specified in the frozen spec before running. |
| `disc-`| Discovery | LLM was run WITHOUT the spec first to capture the raw error, then corrected. |
| `loop-`| Loop      | Full multi-turn Builder/Critic cycle with gate scores. |

## STEP 2 — Prefix Assignment for All 28 Complete Experiments

Apply these renames exactly. If the directory already has the correct prefix, skip it.
