Preserve inventory source coalescing and refresh output partitioning after optimizer rewrites. Cover Arrow and Lance scans beyond the first source partition and the unmodified IC14 query over real relationship records.
Materialize path records only when their consumers need values or relationships. Track shortest-path aliases before checking demand and retain node labels for homogeneous property comprehensions.

Problem and change
Part of #20. Keep the tracker open for the other feature groups.
Named paths now retain ordered node and actual relationship occurrences through RETURN, collect and
UNWIND. Parallel relationships remain distinguishable even with identical endpoints and properties.
relationships,startNodeandendNodeexpose the stored records. Publicnodes(path)remains a listof integer keys; property comprehensions use typed node records to preserve identity across labels.
Shortest paths that cross labels retain that identity even when only length or keys are requested.
Homogeneous length/key consumers keep their compact CSR route through WITH aliases.

The release receipt pins wheel/archive identity and 961 installed tests.Both complete workloads pass unchanged goldens in memory and lazy modes. Retained first-pass geometric mean speedups are below (greater than one is faster). Per-query results and paired investigations remain in the audit archive.
Measurements use the same Apple M4 Max (16 cores, 128 GiB), macOS 26.6.2 arm64 and Python 3.13.17, with Q30 revision

The frozen main baseline is code-identical to current main90114f3; the equivalence check also verifies clean prospective main-target merges.This is a coordinated draft. Preserve its frozen-head outcomes and apply the shared corrections in the qualified integration; changing the actual target requires requalification. The accepted combined engine source is

Named paths retain ordered node and real relationship occurrences, including parallel edges. Edge identities are query-local; rich inventory memory scales with source tables. Compact consumers retain their CSR route. Record contracts, Rust migration and examples are documented.
