"""
Tests for `NominationIntakeFilter` in scripts/calibrate_helpers.py.

Covers tasks 2.1/2.2 of the calibrate-assessment-inventory change: the
deterministic, no-model filter that runs between haiku nomination and the
strong-model judge (lifecycle-spec.md §8 step 3, calibrate spec's
"Deterministic Nomination Intake Filter" requirement).

sys.path is patched here (no shared conftest), matching the existing
tests/test_calibrate_helpers.py pattern.
