# Open-weight Frontier Ledger Ledger — Reproducibility data (v0.2)

**Real-data ledger** produced via the full deep-loop methodology
(8 parallel Opus research-agent sweeps + hand-arbitration).

## Files

- `bills_draft.md` — v0.2 bills definition (14 bills, 6 meta-costs,
  3 escape gates, ★ at Bills 5, 8, 11)
- `purpose.md` — threat model, scope, empty-space hypothesis
- `_batch_1_union.json` — deduplicated union of 8 sweeps;
  371 unique papers
- `bill_classifier.py` — regex + hand-arbitration logic
- `aggregate_batch_1.py` — sweep aggregator
- `README.md` — this file

## Real-data summary

```
8 sweeps × ~46 papers/sweep avg = ~372 raw → 371 unique
Bills 5, 8, 11 ★ NO CLEAN TRIGGER YET:
  Bill 5  — 24 cands / 0 clean / 6 rebuttals / 18 gated
  Bill 8  — 11 cands / 0 clean / 0 rebuttals / 11 gated
  Bill 11  — 36 cands / 0 clean / 4 rebuttals / 32 gated
Rebuttal density: 19.9% (74 papers)
```

## How to reproduce

```bash
python3 aggregate_batch_1.py
python3 bill_classifier.py --arbitrate-union
python3 bill_classifier.py --benchmark
```
