MathlibPR
MathlibPR
MathlibPR is built from real Mathlib4 pull request histories and evaluates merge-readiness judgments for build-passing snapshots. Each snapshot has a binary reference label, but evaluated systems may return one of three final verdicts: merge_ready, not_merge_ready, or uncertain.
Dataset Summary
Full benchmark size: 15,895 snapshots
Label distribution: 11,409 merge_ready, 4,486 not_merge_ready
Within-PR pair dataset: 3,687 pairs

Mathlib Normalized S-Expressions
Lean 4 proof states from Mathlib, paired with the tactic applied at each
step, in three representations extracted directly from the Lean kernel:
Source-faithful S-expressions of the goal and every hypothesis, as
Lean elaborated them.
Normalized S-expressions of the same state, with stable local-context
indices suitable for model input.
Annotated tactic syntax -- the original tactic's syntax tree with
identifier leaves resolved to the constants… See the full description on the dataset page: https://huggingface.co/datasets/jajostrains/Mathlib-Normalized-Sexpr.lean-mathlib-hashmapmathlib_informal_v4.19.0mathlib4-state-changemathlib-refactor-history
Mathlib Refactor History
This release is a source-level history of public declarations in
leanprover-community/mathlib4,
pinned to commit e72c1e277f31441626621f7d0c7207862fc25569. It connects a complete
commit index to statement-change scans and lossless before/after bundles for
refactor-shaped historical events.
The package contains 157.7 MiB of compressed/derived data in
17 data files. Exact byte counts and both compressed and
canonical SHA-256 digests are recorded in… See the full description on the dataset page: https://huggingface.co/datasets/princhernwang/mathlib-refactor-history.mathlib_RL_v2mathlib_v2canonical-drafter-extract-mathlib
Canonical Drafter — extract data (raw)
Ground-truth drafter/premise data lifted from existing Mathlib proofs by
Training/ExtractData.lean. This is the raw pool (429303 draft rows,
664445 premise rows from: Mathlib). Every row is a real have / closed
subgoal taken from a checked proof, so there are no success/used flags to filter
on. Columns follow the uniform schema shared with the rollout dataset, so the two
pools concatenate cleanly.
