When to revisit the conclusion

VG-C01 · 2026-10-22

Current evidence

Grouped valuation remains a conditional historical draft. Reconstructed ST and financial histories are not certified revision-safe; market coverage and executable portfolios are unverified.

Evidence still needed

Archive first-seen financial versions and eligibility, retain all five groups, and observe 12 planned future monthly cohorts under the frozen execution rules.

When the judgment changes

Source repairs materially alter group differences, or matched future evidence fails to reproduce them. Missing or unresolved assets prevent a complete-return judgment.

Review trigger

Review each cohort, any accounting or eligibility correction, and the final 20-session exit window. Keep absent observations on the planned calendar.

Future observation status

Not started. The frozen protocol allows the first formation no earlier than November 2026 and only after the actual freeze timestamp. Calendar, first-seen data and execution receipts must be collected before admission. No completed future performance is reported.
