Gil (Python — iyulab-gil)

Gil answers the decided attributes of a record from the records people have already settled, and chooses — by replaying them in the order they were settled — how far each answer can be trusted and how often a trusted one will be right.

This package binds its Rust decision core: replay settled records to choose how far each layer's answers for a schema attribute can be trusted, and get back the decision records the choice rests on.

pip install iyulab-gil

import gil

schema = gil.Schema.from_dict(
    {
        "name": "ticket",
        "attributes": [
            {"name": "product", "role": "observed"},
            {"name": "summary", "role": "observed"},
            {"name": "team", "role": "decided"},
        ],
    }
)
records = gil.read_records(
    "settled.jsonl"
)  # one JSON object per line, in settlement order
thresholds, decisions = gil.select_layers(
    schema, "team", records, target_precision=0.8
)
print(thresholds["key"]["chosen"], len(decisions))

Before choosing thresholds, narrow the attributes that key the decided attribute. An attribute that happened to settle with one value for a while would otherwise key every later record that shares it:

choice = gil.select_key_fields(schema, "team", records, target_precision=0.8, minimum_answered=30)
definition = {
    "name": "ticket",
    "attributes": [
        {"name": "product", "role": "observed"},
        {"name": "summary", "role": "observed"},
        {"name": "team", "role": "decided", "key_fields": choice["key_fields"]},
    ],
}
thresholds, decisions = gil.select_layers(
    gil.Schema.from_dict(definition), "team", records, target_precision=0.8
)

key_fields is None when no narrower set did better than every attribute — leave it unset then.

The other settings follow the same pattern — choose, then set on the attribute: select_key_concentrations (set as key_concentrations, after key_fields) and, for an attribute with a coarse level ("coarse": {"prefix": 2}), select_coarse once its value thresholds are set.

Status: early. The API may change within 0.x — each change is listed in CHANGELOG.md with what to do about it.
