That was wrong and is corrected here. k30_dn_63 and crypto_carry_wk are BLESSED research artifacts, deliberately frozen -- k30_dn_63 is pinned by a signed construction-drift disclosure in scripts/alphamax_tick.sh, crypto_carry_wk is the canonical universe source several probes cite, and no tick regenerates either. Their 2026-06-01 end is by design. The common window is therefore a structural property of the evidence base, not neglect, and it cannot be extended by re-running anything.",

On the window measured here that cap is 728 days, below the 756 the contract requires. This is a real property of the gate, not a defect in the candidate: a book whose own common history is short cannot admit anything, however long the candidate's record. Recorded rather than lowered -- a correlation is the quantity this whole programme turns on, and measuring it on one year is the reason the minimum was raised in the first place.",

A correlation can only be estimated from days on which both series are genuinely active, which is 728. correlation_observations means the second. Reporting only the first would overstate how well the correlation is known; reporting only the second understates how long the book has run.",
