How the Notebook works
The evaluation cycle.
Each report captures the judgment, states its uncertainty, checks it against additional evidence, and defines what should be examined next.
- 01Record the lookObservation and context
- 02Make the callInterpretation, grades and projection
- 03State confidenceCertainty, risk and limitations
- 04Check the evidencePerformance data and player history
- 05Review and improveReconciliation, next look and retrospective
Technical demonstration
Run the current multi-source pipeline.
This interactive demonstration uses the same role- and level-aware data path as the Notebook. It resolves a player through MLBAM, determines current assignment and competition level, loads the correct official-stat schema, and checks independent advanced sources where coverage is valid.
- 01Resolve identityMatch the player to a stable MLBAM record.
- 02Determine contextIdentify assignment, level, position and role.
- 03Load correct statsKeep hitter, pitcher and competition-level schemas separate.
- 04Check other sourcesQuery tracking and value data only where coverage applies.
- 05Preserve provenanceRetain source, definition, availability and capture time.

Statcast contact, swing, bat-tracking, defense and running data where public coverage exists.
Baseball-Reference
MLB WAR and run components from the official daily value dataset.
