No previous comparable run available.

Current portfolio (saved closing capital weights):
- EXAMPLEBD: 51.64%
- EXAMPLEEQ: 48.36%

Measured risk: one-session volatility 0.430%; window 2024-01-03 through 2025-02-03; ESS 272.0.

Largest absolute asset variance allocations (decimal return squared per session):
- EXAMPLEEQ: 1.95233e-05
- EXAMPLEBD: -1.02814e-06

Proposed portfolio: none committed.
Benchmark: not selected; no benchmark performance implied.

Validation: Empirical incremental value unavailable. Deterministic synthetic mechanics only; no strategy or alpha result is claimed.

Questions for review:
- Why do equal initial capital weights produce unequal variance allocations in this generated example? Inspect closing weights, signed loadings and residual covariance.
- Do the historical conditional concentration and stability estimates justify closer review? They are not forward stress forecasts.
- Confirm the portfolio mandate and data coverage. A readiness pass means usable data, not allocation advice.

Historical covariance/statistics and current-holdings accounting are not forecasts or an actual account record. Membership probability is separate from fit quality and forecast calibration. Conditional sample/estimation uncertainty, proxy limitations and vintage/execution gaps remain in the signed evidence bundle.

Persistence: export/restore; session history does not survive a new connection or server restart.
