research: universo top-liquidità DINAMICO per XS — anch'esso peggiore del fisso-19 (memecoin diluiscono)

xsec_dynuniverse.py: a ogni ribilancio top-N per dollar-volume 30g causale (ragged-aware), poi XS
momentum. Esito: best dinamico top12 FULL 0.65/OOS0.54 (un anno neg) vs fisso-19 FULL 0.80/OOS1.20
(100% anni+). Contributo TP01+DYN 1.10/0.60 vs TP01+XS19 1.25/1.15. La classifica per volume ammette
i MEMECOIN ad alto volume (WIF/ORDI/JUP) erratici -> diluiscono. Liquidità != qualità.

Conclusione: ne' 52-all ne' top-liquidità dinamico battono i 19 major curati. XS01 resta sui 19.
Portafoglio invariato TP01 70% + XS01 30% (FULL 1.41 / HOLD 1.15). 12 test ok. I 52 parquet restano
per ricerca futura. Diario 2026-06-19-xsec-universe-expansion.md aggiornato.

"""XS cross-sectional con UNIVERSO TOP-LIQUIDITÀ DINAMICO (Hyperliquid 52 certificati).
Invece di 19 nomi fissi, a ogni ribilancio: seleziona i top-N per liquidità (dollar-volume 30g
causale), poi fra quelli long i k più forti / short i k più deboli (momentum, market-neutral),
vol-target. Idea: cross-section pulita e ADATTIVA (i token entrano quando maturano in liquidità),
escludendo il long-tail rumoroso che diluiva il 52-all. Gestione ragged (asset a date diverse:
si classifica solo fra i disponibili). Causale. Confronto vs fisso-19 + 52-all + contributo TP01.
