Release 0.7.0 of grid-rbd: the foundation batch (constant-joint ownership, consumer artifact schema 2, collision margins, GLASS 6a82320 with the restrict policy, coordinate metadata and composition views) plus the fold-in agreed on 2026-10-31 (strict spherizer, model_descriptor, fp64 cells in the alpha lane, consumer-cache hygiene) and the release receipt.

The full changelog entry is CHANGELOG.md under [0.7.0]; the migration steps are on the documentation's Migrating to 0.7 page. 43 commits over main 712df1c.

Receipt. gpu-proof.json was recorded at 607efc2c in one fresh full pass on the RTX 5090 (48 shards, 2103 pytest outcomes, 2056 gpu_proof node ids, 0 failures, 0 errors, 0 skips, 0 carried shards) and verifies under both test/gpu-proof-policy.yaml and test/gpu-proof-policy-release.yaml; run_validation.py --finalize reports "Receipt verified". The manifest test/gpu-proof-tests.txt was regenerated from a first full pass at the freeze commit and reviewed: one id renamed (cxx11 to cxx17 layout test), 146 ids added by the new suites, their float twins and the strict-collision and margin tests. That first pass also exposed a probe defect in the collision environment runner (a device-global free-memory comparison that a sibling shard disturbs); it is now a per-pointer check (7737f5a), and that commit is in the receipt's ancestry.

Gates at the freeze. CPU lane 1629 passed, Sphinx strict clean, byte gate 8/8 identical, make release-check PASS (wheel grid_rbd-0.7.0 manylinux_2_34), fp64 alpha lane 59 passed.

Peers. GLASS 6a82320, RBDReference d43ed63, URDFParser 03bf3c3, all on their mains.

Merge with a merge commit, not a squash: the receipt's commit ancestry must survive. The Jetson Orin sm_87 receipt is recording at 607efc2c and lands as a documentation-only descendant after the release; it does not gate this PR or the tag.
