Conversation
maturin/pyo3 build, abi3-py39 unconditional (one cp39-abi3 wheel). lance-core/lance-linalg (pulled in transitively via lance = "7.0.0") have no riscv64 SIMD fallback, same gap already patched for pylance/ lancedb/rerun-sdk; vendor riscv64-fixed crates.io copies and redirect via [patch.crates-io]. Also drops the unused lance-graph dependency, whose own 1.x pin of the same two crates can't be patched alongside the 7.0.0 one Cargo's [patch] table allows only one redirect per name.

Patches
0001-remove-unused-lance-graph-dependency.patch- To upstream, not submitted. Drops a dead dependency blocking the two patches below.0002-lance-core-riscv64-simd-fallback.patch- To upstream, not submitted. Without it lance-core fails to compile (expected SimdSupport, found ()). riscv64-only.0003-cargo-patch-lance-crates-for-riscv64.patch- Inappropriate, build-time only. Redirects the two crates to the patched copies above.0004-lance-linalg-riscv64-simd-fallback.patch- To upstream, not submitted. Without it lance-linalg's SIMD types don't exist on riscv64.Built on cp312; CI pending.
