+# Curriculum Contamination Coherent-Wrong-Label Tasks (Stage 1)
+
+This private pre-release contains a controlled mathematical task bank for
+studying whether self-evolving curriculum selectors can admit an objectively
+wrong answer when repeated solver samples form a coherent majority.
+
+## Dataset contents
+
+- `data/unique_tasks.jsonl`: 240 unique, exact-answer mathematical tasks.
+- `data/label_twins.jsonl`: 480 surface-identical task/reference pairs: one
+  objectively correct reference and one plausible but objectively incorrect
+  reference for each task.
+- `metadata/validation_report.json`: construction and validation summary.
+- `metadata/*.integrity.json`: line-count and SHA-256 integrity records.
+
+The 240 tasks cover ten families, with 24 tasks per family:
+
+1. area scaling;
+2. at-least-one probability;
+3. Bayesian positive-test reasoning;
+4. combined work rates;
+5. equal-distance average speed;
+6. recurrence indexing;
+7. repeated-object permutations;
+8. successive percentage change;
+9. weighted means;
+10. probability without replacement.
+
+## Important interpretation boundary
+
+The plausible wrong answer encodes a prespecified candidate shortcut. It is not
+claimed to be a model error until an evaluator run independently observes it.
+Fields such as `candidate_shortcut_not_observed_model_behavior` and
+`selector_observation_status: not_yet_run` preserve this distinction.
+
+This Stage 1 release contains no completed selector outcome, natural-prevalence
+estimate, training-effect estimate, or closed-loop contamination result.
+
+## Construction and validation
+
+- All 240 tasks have a unique exact answer under an independent deterministic
+  verifier.
+- The plausible wrong answer differs from the objective answer for every task.
+- All 240 correct/wrong pairs have identical question text.
+- Thirty tasks were included in a blinded machine audit during construction.
+- The persisted validation report records 240/240 independent oracle passes and
+  no construction errors.
+
+## Schema overview
+
+`unique_tasks.jsonl` includes the question, family, parameters, objective answer,
+plausible wrong answer, misconception identifier and verifier certificate.
+
+`label_twins.jsonl` includes the shared question and one proposed reference per
+row, with `condition` and `reference_correctness` distinguishing the pair.
+
+## Intended uses
+
+- diagnostic evaluation of majority-vote pseudo-labeling;
+- controlled curriculum-admission studies;
+- comparison of selector risk/retention frontiers;
+- paired causal studies of correct versus coherent-wrong training updates.
+
+## Limitations
+
+- The pool is controlled and deliberately enriched for candidate shortcuts; it
+  does not estimate their prevalence in naturally generated curricula.
+- It currently covers exact-answer English mathematical tasks only.
+- Candidate wrong answers are mechanism probes, not labels of observed model
+  behavior.
+- Downstream learning harm must be established by a separate intervention.
+
+## License and citation
+
+No public-use license or paper citation is assigned in this private pre-release.
+They will be added only after an explicit owner decision and double-blind release
+review.
