P4.5 weighted-path RLS checkpoint

This directory retains one PG17 functional/performance sample for the P4.5 resumable weighted-path executor. It is a checkpoint, not a statistical latency claim.

The run used 10,000 scalar nodes, 10,000 composite nodes, no warmups, and the p3_selective profile. The weighted-path rows in summary.csv show:

  • eager caller-RLS path: 9,598.182 ms and 30,000 source rows;
  • lazy caller-RLS path: 57.649 ms, 5 visibility SPI calls, 5 requested keys, and 5 returned source rows;
  • no-RLS automatic path: 34.731 ms and zero visibility SPI/source rows.

The profile also reran the established BFS, DFS, and unweighted-path gates. run-metadata.txt, logs, plans, samples, summaries, database metadata, and the dirty-tree record preserve the exact environment. Reproduce from graph/ by running tests/heavy/rls_large_table_baseline.sh with the settings recorded in run-metadata.txt and RUN_PROFILE=p3_selective.
