A source-checked result verifies the numerical transcription, not every model or protocol detail. Evaluation metadata: source checked. Source checked does not mean independently reproduced.
Reproduction
- Split
- Validation set
- Adaptation
- Thresholds fixed on the derivation set: (genome coverage >= 1 read > 0.25% OR area under the genome > 0.003 OR reads mapping to the reference > 0.006%) AND >= 2 target reads AND ratio criterion > 0.1; super-accuracy basecalling
- Scoring implementation
- Target-level sensitivity and specificity against routine multiplex PCR
No execution recipe has been verified for this exact configuration and evaluation. A benchmark's general instructions may use different inputs, splits or model settings.
Reproducing this published result requires matching its model configuration, data, split and scorer. Source checking or a successful smoke test does not establish score reproduction.
Evidence
Source checking verifies the cited claim or transcription. It does not establish independent reproduction.
Evidence table
Inspect claims, sources and review details
Trace each statement to its source and review. A context-only reference supports the record generally; it does not verify an individual field. Source checking does not reproduce an experiment.
One row per statement and cited source. Multiple citations are not independent evaluations. Shared locators are labelled explicitly.
