TSPES asks whether the mature family can solve standard instances extremely well.
Why six?
Because one leaderboard would flatten different scientific roles. A strong product solver, a plateau donor, a hard-tail successor, a falsification arena and two native research systems should not be judged by one scalar.
DEV2.3 and DEV2.4 ask whether architectural changes actually beat the proven donor.
RPHS and both 8zTSP-R branches test mechanisms that may matter only at particular scales, phases or representations.
The six lines
Current numbers below use the verified 18 September Home extract, with retained Work evidence where that branch is Work-hosted. Historical numbers are explicitly marked as such.
Mature product / solver research
The strongest current solver line. Exact optimum has been reached on wi29, dj38, qa194, uy734 and zi929. Fresh 22 September evidence has active lu980 = 11,352 versus optimum 11,340: only 12 units remain, a 0.105820% gap. The active continuation is at cycle 2 with 563,748 committed proposals.
Proven nu3496 hard-tail donor
The continuous donor remains at 96,780 on nu3496, 648 above the 96,132 optimum. Direct 22 September Cockpit status shows the native process ALIVE at cycle 26 / branch index 3 / 178 variants completed. The 96,780 campaign incumbent predates the current native branch, so it is not attributed to that branch.
Hard-tail successor / control
DEV2.4 has physically exercised the strict hybrid GPU+Rust stack and still holds 96,780 after 893,426 global proposals. The fresh committed checkpoint is generation 55,935 in the direct native status. Independent validation remains PASS. Added search has not improved the incumbent, which is useful negative evidence rather than superiority.
Representation / sensor falsification line
Active uy734 W4 remains at 79,288 / 79,114 = 0.219936% and has advanced to cycle 226 / 1,811 completed chunks. The same numerical best previously appeared in historical W6 under the N2_shuffled_reverse null control; active W4 carries A1_scale_coherence. The matched numerical result is real while causal interpretation remains open.
Pure relational / native discovery
This line is not a competitive product solver. All 9 of 9 instances have committed snapshots. Fresh Work evidence has advanced the campaign to round 241; the latest verified completed visit is rw1621, while the current pending instance is mu1979 with 15,408 proposals committed toward a 15,424 target. Representation value remains contextual rather than universal.
Multi-View Compression Native
The newest line asks the founding compression question most directly: can multiple description-complexity views become useful search coordinates? It has eight matched lanes including legacy compression, CMVC, combined views, compression-blind and native-distance controls. The fresh committed snapshot is at generation 8 with 32/64 proposals and best length 43,487. No full visit has completed yet, so no performance-advantage claim is made.
