You are a linguist solving a puzzle about {task_lang}, an unfamiliar language. You are given attested sentence pairs. Induce the grammar and output it as JSON — the grammar will be EXECUTED BY A MACHINE, so it must be complete and mechanical.

Attested data ({task_lang} = {work_lang})

{pairs_block}

Hints from the puzzle

{hints_block}

Automatic analysis (may contain errors — trust the data over this)

Morpheme segmentation of {task_lang} words: {segmentation_block}

Word alignments (task-language token -> likely meaning): {alignment_block}

Output format

Emit ONLY a JSON object: {{ "lexicon": [{{"morph": "", "gloss": "<{work_lang} word(s)>", "pos": "<N|V|ADJ|...>"}}], "affixes": [{{"position": "prefix|suffix|circumfix", "form": "", "form2": "<circumfix 2nd part>", "feature": "<the {work_lang} word or marker this realizes, e.g. 'the', 'plural'>", "trigger": "<pos it attaches to, or empty>"}}], "rewrites": [{{"pattern": "", "repl": "", "context": ""}}], "order": ["<pos tags in {task_lang} constituent order, e.g. V, N>"], "agree": [], "redup": [] }}

Rules:

• Every {task_lang} morpheme in the data must be accounted for (lexicon or affix).
• Prefer affix feature values that are actual {work_lang} function words ("the", "will", "not") — they are emitted verbatim when translating into {work_lang}.
• rewrites capture sound changes at morpheme boundaries (e.g. "aa" -> "a").
• The grammar must reproduce EVERY attested pair exactly when executed.
• Simplest grammar that fits wins. No prose, JSON only.
