Risk information, independently assessed.

Context adds short-horizon BTC risk information beyond historical volatility persistence: H+C improves both primary losses against HAR-basis on the frozen independent assessment.

Independent comparison of the fixed H_PLUS_C model and B4B_HAR_BASIS baseline on the frozen assessment.

Consistency across chronology

Consistency across four chronological segments, not four independent replications.

Calendar/liquidity structure, volatility compression and expansion, and shock normalization added information beyond the strong HAR-basis model within the frozen assessment.

The conclusion is specific to the fixed model, the named strong baseline and this frozen assessment. It does not establish a directional timing rule.

The actual-to-forecast variance ratio describes calibration at the reported aggregation level. Proximity to one does not establish perfect conditional calibration or accurate tail calibration.

What the supplied evidence does not establish

• The reported aggregate improvements do not supply confidence intervals, p-values, segment sample sizes or economic significance.
• Chronological segment consistency does not establish independent replication.
• Calibration evidence at the reported aggregation level; not proof of perfect conditional or tail calibration.
• Forecast validation does not provide live trading permission or automatic veto authority.

The public summary does not infer unreported confidence intervals, significance levels or loss-normalization formulas. Those require the underlying assessment report.

Question

Does the risk candidate survive comparison with a stronger volatility-persistence alternative?

Method and finding

Challenge the candidate against a stronger baseline during development.

The risk candidate passed the strong-baseline challenge described in the reviewed research brief.

Passing a development comparison does not itself establish independent confirmation.

No numerical result, exact baseline specification or development assessment dates were supplied.

The independent assessment above is the completed follow-up. Its model identifiers and dates are not a substitute for this development study's missing specification.

FORECAST_INFORMATION_WITHOUT_POLICY_UTILITY

Question

Can the frozen primary P3 mapping turn stronger H+C risk information into policy utility under the preregistered rule?

Frozen test

Frozen primary P3 policy evaluation against the preregistered utility threshold and required multi-era consistency rule.

Policy utility was not confirmed

Forecast information survived; the preregistered policy-utility claim did not.

• Both primary pooled improvements missed the preregistered minimum.
• Only CONFIRMED_FORECAST_ERA_DIAGNOSTIC passed the joint era rule; required multi-era consistency failed.
• The policy assessment has its own protocol. It does not inherit the forecast assessment window or independence label.

What the mechanism evidence supports

• H+C retains better realized-risk ranking than HAR.
• H+C has materially lower turnover than HAR; much of its relative fee-net return advantage is associated with lower turnover.
• Opportunity cost remains. Better ranking and lower turnover do not override the failed frozen P3 rule.

Mechanism associations do not establish a completed causal decomposition or directional timing.

These observed relationships motivate a separate decomposition question. They do not override the frozen primary rule or turn risk ranking into directional timing evidence.

Research records are maintained in the private research archive. The reviewed briefs support the claims shown here; public reports, manifests and reproducible code destinations are not yet available.

The policy study's supplied branch-head identifier belongs only to that completed study. It is not the independent forecast assessment's code lineage.
