argumentative-zoning

# Argumentative Zoning ## Orchestration Pattern 1. Fetch the paper; stop on `not_found`. 2. Segment the requested scope with sentence granularity and preserve `{line, start, end}` offsets. Write `01-unit-segmentation.json`. 3. Classify every unit with `label_set: argumentative-zoning`, `hierarchy_toggle: false`, and `output_type: single_label`. Write `02-unit-classification.json`. Use exactly AIM, BACKGROUND, OWN, CONTRAST, BASIS, TEXTUAL, and OTHER. Every sentence receives one label; use OTHER rather than skipping an uncertain unit. Narrow scopes are valid but not distributionally comparable to a full-text run. Report scope, sentence count, zone counts, empty zones, and both paths.
