Module reason 

Exclusion reasons of the origin metrics (3.5).

Constants

ABSENT

Extraction accuracy: the value is absent, which absence_rate counts.

EMPTY

Screening: an empty value, which sends no request (spec 035, 3.6.1).

NOT_IN_PLAN

The case’s plan has no such construct (3.5.3).

NOT_RUN

Acquisition tier: the decision did not reach the widening step.

NO_EVIDENCE

The case has a proposal but no core evidence record.

NO_GOLD

Extraction accuracy: the gold record states nothing for the field.

NO_OUTCOME

Corroboration: no step ended corroborated or contradicted.

NO_RESULT

Extraction: the case’s extract step has no result for the field.

NO_SCREENED_FIELD

Screening: no non-empty value was screened by this screener.

NO_SLOT

Text backstop: a generate step ran with no field slot.

SKIPPED

Acquisition tier: every tier was skipped by its guard. Text backstop: every generate step was skipped (spec 037).

TYPE_MISMATCH

Extraction accuracy: the value and gold kinds do not pair (3.3.3).

UNCORROBORATED

Corroboration: an uncorroborated outcome, outside the denominator.

VALUE_NOT_RETAINED

Extraction accuracy: spec 038 keeps only the digest of this field’s type, so the value cannot be compared (R-19).
