Upstream a4d4a249. Dig tables, Capricorn's first half, the sputa formula, and the benefic set now match jyotishganit_mirrored_equal_house_v2. Mercury is neutral. The result names that profile and does not call it a classical ruling. BUG-1385. Co-Authored-By: Grok (agent loop) Co-authored-by: Cursor <cursoragent@cursor.com>
