Re-verified all 93 tracked listings (WebSearch+WebFetch): 2 sales recorded (Neo Genesis 1st Ed box $88,888 Aug 25; Mario Pikachu PSA 10 $88,888 Sep 2), Rayquaza Gold Star PSA 10 ask raised to ~$88,888 (EUR 1,299,999), 3 new asks added; no source fully blocked, though eBay pages needed search-provenance and a few catalog redirects were skipped.

16:45 UTC — build v53 · full Card Ladder sweep + analytics

Card Ladder sweep of the remaining 159 chases across Fossil, Base Set, Base Set 2, Team Rocket, Neo Genesis/Discovery/Revelation/Destiny, Expedition, Aquapolis and Skyridge (ladders exist for ~45 of them; Expedition, Base Set 2 and most Unlimited prints have none and stay on PriceCharting guides) plus ~1,100 dated PSA 7–9 / raw sales with eBay links · Neo Genesis Typhlosion #17 1st Ed $88,888→$88,888 (Card Ladder Jun 4, pop 13; a further $88,888 private sale Aug 10 via Nostalgix is on the tape but does not set the mark) · Base Chansey 1st Ed $88,888→$88,888 (Jul 9, pop 48, single sale) · Neo Revelation Blissey 1st Ed $88,888→$88,888 (Jun 25, pop 11) · Houndoom 1st Ed $88,888→$88,888 · Neo Genesis Pichu $88,888→$88,888 · Meganium $88,888→$88,888 · Skyridge Umbreon H30 $88,888→$88,888 · Aquapolis Espeon H9 $88,888→$88,888 · Base Hitmonchan 1st Ed $88,888→$88,888 · Base Pikachu Red Cheeks $88,888→$88,888 · Fossil Dragonite 1st Ed $88,888→$88,888 · Heracross 1st Ed $88,888→$88,888 (guide) · print hygiene added: a recent "PSA 10" print under 40% of the mark is rejected as a mis-labelled grade (4 caught, incl. a $88,888 Mewtwo 1st Ed ladder row and a $88,888 Rayquaza ★ print), ladder rows older than Jan 2025 never set today's mark, and the current partial month needs ≥2 sales in a grade before it counts · new analytics: drawdown & recovery table and rolling 12-month correlation to .AGG, gold (GC=F month-end) and the S&P 500 on every index page; Stale Marks screen on F6 · PSA 10 pops filled for the 7 Poncho promos that lacked one (Card Ladder / PriceCharting pop report, Sep 4) and for Rocket's Snorlax Unlimited and Shining Gyarados Double Holo Error (Pikawiz) — every tracked card now carries a sourced PSA 10 pop

14:29 UTC — build v50 · factor-weighted, monthly-rebalanced variants

Every card index now has a -W twin on the benchmark board (17 added: .GLDSTR-W, .PONCHO-W, .CRYSTAL-W, .MOMO-W … .1STED-W). At each month start members are z-scored on ln PSA 10 mark, ln gem market cap, ln slab premium and −ln pop, averaged, mapped to weight ∝ e^z, capped 25% / floored 1%; weights float with price inside the month and reset at the next month start; level chains Σ w × return from 1,000. Value and mcap use the prior month-end mark only; pop and raw are the latest snapshot (no history exists). Each -W page shows the full weight table (z-scores, target vs floating), the rebalance log with turnover, and a Σ w × r = month-return check. Engine verified against an independent recomputation (.GLDSTR-W 3,823.9 both ways). Day-by-day changes are not observable from monthly marks — 1D pace remains pro-rated.
