"""ZOMBIE-WEIGHTS dataset builder (Phase 0/1).

Builds four strictly separated artifact groups with zero train/eval overlap:

  Arm A (academic WMDP)
    * forget-train prose: cais/wmdp-corpora cyber-forget-corpus +
      declarative prose from a strict topic-disjoint 40% slice of wmdp-bio
    * held-out eval MCQ: 300 wmdp-cyber + 300 wmdp-bio questions in
      EN / HI / Hinglish / AR / FR / ES (answer index preserved)

  Arm B (canary secret extraction)
    * 200 synthetic enterprise PII records with CANARY-ZW-XXXX tokens
    * held-out extraction prompts (direct, JSON-wrap, Hinglish, Hindi, Arabic)

  Controls
    * CohereLabs/Global-MMLU en/hi/ar (300 each)
    * bench-llm/or-bench hard-1k English (300)
    * 100 hand-written benign Hinglish/Arabic dual-use prompts

Every corpus is routed through CuratorKIT so each output directory carries
``manifest.json`` + ``lexsi_provenance.json``.  Translations use a real
backend (local Opus-MT / NLLB or the HF Inference API) and are validated;
there is no placeholder fallback.

Usage:
    python -m src.data.build_datasets --out data/curated --translator opus-local
    python -m src.data.build_datasets --out data/curated --push

# ZOMBIE-WEIGHTS Bench

Zero-overlap unlearning benchmark built for the Lexsi AI Safety hackathon.

## Contents

| Group | File | Records |
|---|---|---|
| Arm A forget-train prose | `arm_a/train.jsonl` | {arm_a['counts']['train_records']} |
| Arm A held-out MCQ | `arm_a/eval_mcq.jsonl` | {arm_a['counts']['eval_records']} |
| Arm B canary records | `arm_b/train.jsonl` | {arm_b['counts']['train_records']} |
| Arm B held-out prompts | `arm_b/eval_prompts.jsonl` | {arm_b['counts']['eval_prompts']} |
| Global-MMLU controls | `controls/global_mmlu.jsonl` | {controls['counts']['global_mmlu']} |
| OR-Bench controls | `controls/or_bench.jsonl` | {controls['counts']['or_bench']} |
| Benign multilingual | `controls/benign_multilingual.jsonl` | {controls['counts']['benign_multilingual']} |

Arm A eval: n={n_eval} per task per language ({', '.join(LANGS)}), answer index A/B/C/D preserved.
Arm A bio split: strict topic-disjoint, {arm_a['split_stats']['actual_train_fraction']:.1%} train / rest held-out,
Jaccard threshold {arm_a['split_stats']['threshold']}.

**Never uploaded:** `cais/wmdp-bio-forget-corpus` raw text. The bio train prose is derived
from the public MIT-licensed `cais/wmdp` MCQ split, not from the gated forget corpus.

Translations: `{translator_name}` with per-item validation; translations never alter the
answer index. Hinglish is deterministic Devanagari-to-Roman transliteration of the Hindi twin.
Per-method counts are recorded in `manifest.json` (`counts.arm_a.translation_methods`);
`identity_code` / `identity_refused` entries are explicit, counted fallbacks for code or
safety-filtered segments — never synthetic placeholders.

See `manifest.json` and `lexsi_provenance.json` for hashes, counts, and CuratorKIT run provenance.
