## Deep-loop sweep JSON output

Each sweep agent returns an array of paper objects with this exact frontmatter:

## Bill classifier rule format

`scripts/bill_classifier.py` rules are tuples of (regex, bill, confidence-modifier):

```python
RULES = [
    # (pattern, bill, weight)
    (r"\b(LQG|loop\s+quantum\s+gravity)\b.{0,200}\b(area|volume)\s+(?:operator|eigenvalue|spectrum)", "Bill_1", 0.95),
    (r"\bspinfoam\b.{0,200}\b(amplitude|EPRL|FK)", "Bill_2", 0.95),
    (r"\b(CDT|causal\s+dynamical\s+triangulation)\b.{0,200}\b(dimensional\s+flow|spectral\s+dimension)", "Bill_3", 0.95),
    (r"\b(causal\s+set|causet)\b.{0,200}\b(sprinkling|non[- ]locality)", "Bill_4", 0.95),
    (r"\b(asymptotic\s+safety|UV\s+fixed\s+point)\b.{0,200}\b(graviton|Newton|Reuter)", "Bill_5", 0.95),
    (r"\b(GFT|group\s+field\s+theory)\b.{0,200}\b(condensate|cosmology|primordial)", "Bill_6", 0.95),
    # ...
]
```

Two-pattern AND-form rules used for sub-bill resolution:

```python
RULES_AND = [
    # ((p1, p2), bill, weight)
    ((r"\barea\s+(?:operator|spectrum)\b", r"\b(physical\s+Hilbert|inner\s+product|matter)\b"), "Bill_8", 1.0),
    ((r"\bdiscrete\s+spacetime\b", r"\b(observable|prediction|distinguish)\b"), "Bill_11", 0.95),
    ((r"\bcausal\s+set\b", r"\b(swerve|non[- ]locality|Sorkin\s+integral)\b"), "Bill_4", 1.0),
]
```
