The SAM 2.1 hiera-tiny mask decoder re-exported to ONNX (opset 18) so segment can pick an object's whole outline and retry with points (PLAN.md M13, issue #14): it takes the box as its two corner points plus up to eight positive points and returns three candidate outlines with the decoder's predicted IoU of each. Same SAM revision (de431c4), Apache-2.0; the encoder and OWLv2 are unchanged and stay in models-2026-10. Interface and parity (every outline IoU 1.000 against PyTorch, box alone and with 1 and 3 points) in tools/python/MODEL.md; provenance in export.json.

rascal-tools fetch downloads it and checks it against tools/python/src/rascal_tools/artifacts.toml; release bundles carry it under models/.
