"""Build Nirnay's multi-task decision corpus from public datasets.

Every record is one typed question about one state, in the Jev/Laya question spec:
  {"src", "state", "q": {"type", "instructions", "criteria"}, "y": gold option index, "split"}

Held out of training entirely (they are benchmark suites, mirroring Laya's own held-out policy):
  dair-ai/emotion, mteb/banking77, lmsys/toxic-chat (jailbreak + toxicity), openai/gsm8k,
  google-research-datasets/mbpp (model routing), SetFit/sst5, ucirvine/sms_spam, XNLI, MASSIVE,
  and every jailbreak / prompt-injection dataset.
Datasets Laya also trained on (ag_news, enron spam, phishing, support tickets, MS MARCO) contribute
only rows that are not in the benchmark cases, and any state whose text appears in a benchmark
suite is dropped.

v3 adds request routing (code / math / SQL / writing / trivia / small-talk sources, never gsm8k or mbpp),
short-message spam (any text that matches the held-out UCI SMS collection is dropped), request safety
(NVIDIA Aegis 2.0, which is not a jailbreak dataset), urgency questions, and more phrasings of every
shared question template.
