reject edges_per_row values other than 1 or emit exactly the requested number of
edges; ensure their row builders no longer silently discard epr, keeping
multi_edge behavior unchanged.

- Around line 178-181: Update the cleanup logic in the benchmark’s output
handling so shutil.rmtree is used only for a temporary directory created by the
command, never for an explicitly supplied --output-root. Preserve
caller-provided output directories when --keep-output is unset, while still
cleaning up benchmark-owned temporary paths.

Provide the required edge properties.
src/openhound/sources/opengraph/entries.py:Edge declares properties as a required field. This constructor omits it, so every node_and_edge row fails validation before the benchmark can serialize the record. Pass an appropriate EdgeProperties value or use the existing project helper.

Isolate each benchmark run from stale workspace data.
When a caller reuses --output-root, write_synthetic_input writes new partitions without removing partitions from earlier runs. The table directory is consumed by the OpenGraph file glob, so a previous run with more rows or files can silently change the next run's metrics. The same root also reuses output and dlt_work. Use a fresh run directory or clear only benchmark-owned child directories before generating input. Preserve the caller-supplied parent directory.

Summary
The
opengraphconvert source reset its edge-batch accumulator on every source row, so each row emitted its own edge wrapper regardless ofbatch_size. The accumulator now spans the whole graph resource — across rows, DLTread_jsonlchunk boundaries, and input files — flushing one final partial batch at end-of-table. A table ofNedges emits exactlyceil(N / batch_size)wrappers (defaultbatch_size= 150) instead of one per row.Framework optimization only: the flattened relationship sequence (order, duplicates, per-edge content) and all nodes are byte-for-byte identical to before. Only edge grouping changes.
Motivation
Resolved: BED-9372
Changes
src/openhound/sources/opengraph/source.py: accumulator moved outside the per-row loop; single final flush;batch_size < 1rejected; nodes unchanged and never mixed into edge wrappers.tests/test_opengraph_batching.py: 19-test regression suite.benchmarks/: standalone synthetic benchmark harness (not run under pytest) plus a destination memory/part-size review.Guarantees
ceil(total_edges / batch_size), table-wide.batch_size = 1reproduces per-row wrapping;batch_size < 1raisesValueError.Tradeoff: a mid-table failure re-extracts the whole table rather than resuming mid-chunk (documented inline).
Testing
Expect 19 passed — covers cross-row/chunk/file batching, the 1,000-row chunk boundary,
ceil(N/batch_size)counts, order/duplicate parity vs abatch_size=1baseline, edge cases, and per-resource/per-retry isolation.Real-data parity (local, no data committed): replayed against Okta
ApplicationUser(8,577 edges → 58 wrappers) and GitHubRepoRoleAssignment(2,745 edges → 19 wrappers, crosses the chunk boundary, non-Okta). Fixed path,batch_size=1baseline, and frozen output all yield identical canonical SHA-256, with model/lookup/extras held constant.Summary by CodeRabbit
