If I run MEt3R, which reconstruction backbone do the paper and the repository say it uses, and which one do I get by default?

The paper text (arXiv v1 and v2) names DUSt3R as MEt3R's reconstruction model and says MASt3R was not used. The released code at commit ee0e175 defaults to a 'mast3r' backbone (MASt3R weights) and offers 'dust3r' and 'raft' as options, and the README overview still says DUSt3R. So a default run is not the configuration the paper text describes; to match the paper wording pass backbone="dust3r". Whether the paper's tables were produced with DUSt3R weights is not stated by any source read (see candidate 02). Curator qualifications: Conflict confirmed: the paper and README describe DUSt3R, while the released code defaults to MASt3R weights and vendors DUSt3R only inside the mast3r submodule. Wording precision: the paper says it does not use MASt3R's correspondences, which implies but does not literally state that MASt3R was not used. Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary. Limitations: [component_reuse_restriction] Curator readbacks at MEt3R ee0e1752 (met3r.py, README (bytes equal pin), .gitmodules, LICENSE) and arXiv 2501.06336v2 HTML (bytes equal pin); commit 0369fa2 metadata via GitHub API GET; no code run. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
