strip_nevo_preamble's _DECISION_START only matched ועדת-ערר openings (בפנינו /
הערר שבנדון / ...), so Nevo COURT judgments — exactly the ones carrying a
מיני-רציו — slipped through unstripped. The editorial mini-ratio then leaked into
the chunked body, risking that the halacha extractor reads Nevo's answer key
(contamination) and polluting the corpus. Proven on בג"ץ 1764/05: its full_text
still contained the מיני-רציו (unstripped).
Fix:
- Extend _DECISION_START with court-ruling openings: פסק-דין/פסק דין header and
the authoring-judge line (השופט/ת, כב' השופט, הנשיא, המשנה לנשיא). re.search
picks the earliest line-start match → the real opinion start, not the prose
ratio above it.
- Widen the Nevo-marker detection window 400→1500 chars so a long court/parties
header doesn't push חקיקה שאוזכרה:/מיני-רציו: out of range.
Verified on the real 1764/05 full_text: strips 2702 chars, body now starts at
'השופט ס' ג'ובראן:', מיני-רציו gone. Regression: ועדת-ערר openings still strip;
non-Nevo text untouched; markers-past-400 now detected. Suite 182 passed (6 new).
This is the anti-contamination prerequisite for the Nevo-ratio gold-set (#86.3/#81.7).
