Wikimedia memory growth comparison data

This derived dataset supports the memory growth plot. It combines observations from two verified replays on naamah of the same 1,483,700,913-command numeric trace. All endpoints contain 80,798,328 members and the same page-ID-to-score mapping.

• samples.tsv: every recorded sample for the seven plotted curves, followed by each curve's separately recorded final measurement. live_members is ZCARD; os_rss_kib is process RSS in KiB. Chart values divide these by 1,000,000 and 1,048,576 respectively. measurement=sample uses the sample's elapsed seconds; measurement=final uses the timed feed duration from summary.tsv. The plot uses member count as its horizontal axis.
• endpoints.tsv: final RSS and savings relative to the new INT32/FLOAT32 RLE result. This also includes the September 22 RLE-off control, which is tabulated in the report but not drawn over the nearly identical historical packed curve.
• sources.json: exact source paths and SHA-256 hashes, the common numeric input hash, series identities, and axis definitions.

The earlier packed and standard Goblin curves and all four incumbents come from the September 8 six-engine replay. The RLE curve comes from the September 22 twelve-variant replay. These are separate concurrent runs, with different Goblin builds and numbers of clients. The plot compares observed memory growth; it does not compare throughput between runs. Packed curves use INT32/FLOAT32; standard Goblin and incumbents retain their general member representations.

No original observation is smoothed, removed, or replaced. Some incumbent final samples differ by 12 KiB from the separate final reading in summary.tsv; both records are retained. Five-minute samples cannot establish peak RSS. Labels and report savings use the final summary readings.

The generator requires Gnuplot and verifies the recorded statuses, final mapping digests, common input hash, and monotonic member counts before plotting. The two original evidence bundles remain unchanged.
