What was already known
Earlier Euclidean CVP hardness factors were smaller or used different assumptions. Song later reported stronger deterministic factors; that result does not check this reduction.
AI involvement
OpenAI attributes the argument and its Lean formalization to Astra. Humans selected the problem and prepared the manuscript with the model.
OpenAI’s original disclosure assigns the argument and subsequent Lean formalization to Astra; human manuscript preparation is separately credited.

Importance
Establishes polynomial-factor hardness for a foundational lattice problem.
Limitations
The reported Lean certificate covers the stated formal promise. Human reviewers reconstructed the reduction but left some threshold and degree calculations compressed. Song’s stronger theorem is separate.
Technical verification
The project reports a complete Lean certificate for the stated formal theorem. Human assessments have narrower scope; semantic matching and any manuscript gaps remain separately noted.
Independent checking
chapter-specific mathematical review of the published argument, with the limited coverage summarized in the audit. Table 1; Chapter 7 discussion
- Checker
- Chapter 7 human reviewers in the Sienicki et al. review corpus
- Scope
- reduction architecture, valuation and exponent bookkeeping, with compressed thresholds
- Basis
- Reported by the linked checker
Formal checking
Lean 4.32.0 formal certificate in GapCVP.lean; comparator target for GapCVP.Comparator.gapCVP400IsNPHard; manifest reports zero sorry and only standard axioms. main_results entry GapCVP.Comparator.gapCVP400IsNPHard; status and axioms
- Checker
- OpenAI ten-proofs project, Lean kernel and Comparator configuration
- Scope
- n^(1/400)-factor Euclidean GapCVP NP-hard promise
- Basis
- Reported by the linked checker
Checking a formal statement does not establish that it matches the original problem.
Human understanding
Human Chapter 7 reviews reconstruct the Reed–Solomon encoding, algebraic recovery, reduction soundness and exponent conversion, while noting compressed threshold calculations.
