ARB lean-proofs data packet

The data packet of the lean-proofs task of applied-rsi-bench (Thoughtful-Lab): a training pool of Lean 4 statements and proofs, and the case image's Mathlib search index. Nothing here is a test or dev problem of the task.

L.tar.gz	The training pool (revision 2: the 16-gram rule added to the decontamination), in ARB's raw corpus format: PACKET.json (schema 2), README.md and three JSON Lines files	1f8262e6c3bf8ebda805d1db1950c929068b435be0369af3c0133a78f335e5f9
mathlib-names-v4.27.0.tsv.gz	The search_mathlib index: every declaration that import Mathlib and two FormalConjectures modules bring (Lean v4.27.0, Mathlib a3a10db0), without Lean's internal names and the Lean and Lake libraries, one line each: name, module, type as Lean prints it; 408,413 lines	47caaf6157254417b7a3410d4168325750a8efc262f5467c97a433b79d6b5f67 (uncompressed: 76c29a0c9d5a6766a2ebc5d7277982874317fd5d460795ecf3ee6c2dc0b0f10b)

The training pool

Each line of the JSON Lines files: source, id, formal_statement, informal_statement, proof (a whole Lean file, or null), lean (the Lean version the source wrote it for).

The rows are the sources' own, renamed to one schema. Lean Workbook's rows have no id: the theorem's name (lean_workbook_<n>) is the id, the one Lean-workbook-proofs names, and a Lean-workbook-proofs row has its Lean Workbook statement. NuminaMath-LEAN's proof is its formal_ground_truth when ground_truth_type is complete and it has no sorry. The rows were written for Lean v4.8 to v4.15; many statements and proofs do not compile on v4.27.0 as they are.

Decontamination

Every row that matches a problem of the task is removed: all of miniF2F (google-deepmind/miniF2F f0a20e14: 244 test, 256 valid) and all 312 problems of IndiMathBench (prmbiy/IndiMathBench 0eac2a55), test and dev. A row matches when its formal statement (comments, imports, theorem names, the final sorry and whitespace removed) or its informal statement (lowercased, letters and digits only, LaTeX's \dfrac/\tfrac read as \frac, \left/\right left out) equals the problem's; when it shares at least 50 % of the informal word 5-grams or 60 % of the formal token 5-grams (Jaccard); or when it holds at least 10 % of the problem's word 16-grams (the problem as its informal statement, then its Lean statement). 833 rows were removed, matching 359 problems (259 of miniF2F, mostly NuminaMath-LEAN's copies of MATH and AMC problems; 100 of IndiMathBench). ARB's 16-gram probe then finds 0 of the task's 490 test problems with 25 % or more of their 16-grams in the pool. The builder is tasks/lean-proofs/data_packet/build.py in applied-rsi-bench; its decontamination.json lists the removed rows.
