## ADDED Requirements

### Requirement: Long-sample all-window validation
The system SHALL validate ultra-short candidate strategies over a long historical candle range using every non-overlapping evaluation window available for the configured window size.

#### Scenario: Build deterministic validation windows
- **WHEN** robust validation is run for a symbol, bar, history limit, window size, and candidate warmup size
- **THEN** the system MUST evaluate each complete non-overlapping window exactly once
- **THEN** the system MUST report the resulting sample count

### Requirement: Statistical validation metrics
The system SHALL report the statistics needed to evaluate whether a candidate has credible positive gross return.

#### Scenario: Report candidate distribution
- **WHEN** robust validation completes for a candidate
- **THEN** the output MUST include average return, 95% confidence interval lower bound, 95% confidence interval upper bound, median return, positive-window rate, worst return, p10 return, p90 return, best return, trade count, average trades per window, win rate, and max drawdown

### Requirement: Candidate acceptance criterion
The system SHALL treat a candidate as statistically supported only when its 95% confidence interval lower bound is greater than zero on the robust validation run.

#### Scenario: Accept supported candidate
- **WHEN** a candidate's robust validation output has `ci95_low` greater than zero
- **THEN** the candidate MAY be listed as a supported gross-return candidate

#### Scenario: Reject unsupported candidate
- **WHEN** a candidate's robust validation output has `ci95_low` less than or equal to zero
- **THEN** the candidate MUST NOT be listed as a supported gross-return candidate

### Requirement: Gross-return labeling
The system SHALL identify robust validation outputs as gross-return backtest results that exclude fees, slippage, and funding rates.

#### Scenario: Prevent live-profitability claim
- **WHEN** robust validation results are summarized
- **THEN** the summary MUST state that the results do not include fees, slippage, or funding rates
- **THEN** the summary MUST NOT present the candidate as live-trading ready

### Requirement: Current strategy conclusion
The system SHALL preserve the validated conclusion that RSI2 has the strongest current gross-return support and the earlier VWAP candidate is not statistically supported.

#### Scenario: Summarize current robust run
- **WHEN** the robust validation result set includes the latest 50,000-candle BTC/ETH 1m/3m/5m run
- **THEN** the summary MUST identify the top supported RSI2 candidates by confidence interval lower bound
- **THEN** the summary MUST identify VWAP as rejected when its confidence interval lower bound is not positive
