Structured CPT - JSON + SQL pretrain documents

SmolLM2-1.7B continued-pretraining shard of structured documents. Each document is a <task> / <input> / <output> block whose <output> is a canonical JSON object, terminated by the SmolLM2 end-of-text token ``.

Sources:

source	description	rows	shards	repeat
sql_bmc2	b-mc2 sql-create-context -> JSON (4 keys, stub explanation)	392,885	1	5
sql_gretelai	gretelai synthetic_text_to_sql -> JSON (4 keys)	529,255	1	5
sql_hardikch	hardikch05 100000_text_to_sql -> JSON (question/schema_ddl/sql)	5,500,000	28	1
stackexchange_json	Stack Exchange -> JSON (title/body/tags)	836,000	5	1

Totals: 7,258,140 rows.

Document shape

<task>
...
</task>

<input>
...
</input>

<output>

id	unique id {source}-{index}
text	full structured document, trailing ``
text_preview	first 800 characters of text
