MatterGen: a generative model for inorganic materials design
Certiv evidence level
Artifact inventoriedcentral claim independently reproduced?
No.
That answer stays “no” even when a selected check passed.
claim boundary
Three statements that must not be collapsed.
The exact v2 PDF was pinned and the official code repository was commit-inventoried. Its documentation warns that released checkpoints were retrained and may not reproduce paper values; some structures also cannot be shared for licensing reasons.
Material stability, novelty, synthesis feasibility, property accuracy, and the paper's comparative performance were not independently reproduced.
source identity
The paper is versioned bytes.
A mutable title or unversioned link is not enough to reproduce what was reviewed.

These probes reduce ambiguity and obvious PDF attack surface. They are not a comprehensive malware analysis.
Certiv T0 exercise: this exact PDF was hash-pinned without executing its declared command. The unchanged input remained explicitly unverifiable; a one-byte tamper produced a failed input_hash_drift finding.
test record
Checks, failures, and blockers.
Status is always paired with text. A pass applies only to the check and boundary shown in the same row.
Observed
Exact PDF identity
Observed
The downloaded v2 PDF matched the recorded SHA-256, byte count, and page count.
Boundary
This establishes file identity only.
Observed
Official repository inventory
Observed
The public repository was pinned at commit ac9ddd406171138c3f037d06b9b53fedbbb1c536.
Boundary
A repository revision is not a successful reproduction.
Blocked
Paper-equivalent replay
Observed
The released checkpoints are documented as retrained rather than identical, and some ICSD structures are unavailable under licensing limits.
Boundary
A run of the released package would not automatically be a reproduction of the paper experiment.
external artifacts
Pinned, not trusted by default.

Repository documentation says released checkpoints were retrained and can differ from paper results.
red-team findings
Where a confident summary can outrun the evidence.
- Released checkpoints are not the exact paper checkpoints, which prevents bit-for-bit experiment equivalence.
- Licensing limits remove part of the structural evaluation data from the public package.
- The repository's faster ML-force-field evaluation is not equivalent to the paper's DFT evaluation.
- Computational stability predictions do not establish successful physical synthesis.
