Plan-only change. It records an operator decision and the census behind it in .claude/plans/d-xlog-native-v1.md Amendment E.

  • Decision. XLOG's RIR node kinds are assimilated into our algebra IR (Quack / relalg / R2IL → mask-risc, addressed by DT64/DR). XLOG's caller API is kept and polyfilled back onto our substrate. XLOG's runtime is not refactored, and its CudaBuffer plumbing is not ported.
  • Census of the xlog fork at bff6da6 (a Haiku count; three of the numbers re-run by hand and matched):
    • One dispatcher, execute_node_uncached, handles all 13 RIR kinds.
    • 26 operator call sites, plus 40 for execute_node.
    • CudaBuffer appears on 278 lines in xlog-runtime and on 1,924 across the workspace.
  • Coverage today: 7 of the 13 kinds are admitted. The other 6 are refused by type: Union, Distinct, Diff, MultiWayJoin, TensorMaskedJoin, Unit.
  • Open: the exact caller API to polyfill, and where the polyfill lives without an xlog-* dependency in lance-graph.

Cites d-xlog-native Amendment E (#1910) as the decided route: assimilate
into lance-graph-xlog, polyfill the callers, CubeCL over ndarray only for
the residue; CudaBuffer plumbing is not ported. Records that the
device-less provider / CudaBuffer::View idea (#1911) is OPEN and that the
"Amendment F" cited by cube.rs:2 and the D-XLOG-NATIVE-7 entry is absent
from the plan. Adds the per-crate caller-surface count toward E's open
census.
