"""exp15 — reflow-invariant omission metric + Q2b re-attribution ($0). Design §D3 + orchestrator amendments.
|
||
|
||
The metric asks, per SOURCE sentence-atom, whether the atom appears ANYWHERE in the target (position-
|
||
independent = reflow-invariant, so legitimate merge/reorder is NOT penalized). Primary atom = glossary
|
||
ENTITY (design-relevant: entities/terms = 62.5% doc-level errors, BWB).
|
||
|
||
ORCHESTRATOR AMENDMENTS (2026-07-17):
|
||
(1) Entity match by LEMMA (pymorphy3), NOT membership in decl.forms. A form present but outside the
|
||
pinned decl.forms = `inflection_gap` FLAG for span-check, NOT an omission (else the D30.9 §B5
|
||
inflection_gap class fabricates ~7-8% false omissions).
|
||
(2) Pre-registered variance-check: entity-omission ~0 across ALL sizes => report "INSTRUMENT CEILING",
|
||
never "size is safe" (anti-false-negative; the D32.4 lesson).
|
||
(3) Entity-free (holistic) content-drop detection runs ONLY if a crude content-length FLOOR backstop
|
||
fires; otherwise complex drops are span-judge work (don't over-engineer).
|
||
(4) Provenance to BYTE identity: source = records.json chapter_source join (== exp14_sizecurve.py:30-32,
|
||
the exact bytes sizecurve translated). Asserted below.
|
||
|
||
VALIDATION (mandated): the metric is validated on a hand-proofread whole-chapter output BEFORE scoring
|
||
arms — run with --validate <ch> to dump per-entity verdicts for manual read; only after that, --score.
|
||
|
||
Run: eval/.venv/bin/python eval/exp15/reflow_omission.py --validate 13 # dump for hand-proofread
|
||
eval/.venv/bin/python eval/exp15/reflow_omission.py --score # Q2b table (after validation)
