Seasons and manager relationships can come from drafts, completed trades, completed waiver claims, completed free-agent transactions, commissioner adjustments, historical roster snapshots, weekly roster observations, and current rosters.

Failed waiver claims are excluded. Movement history is event-based; roster evidence does not necessarily prove uninterrupted ownership. Commissioner adjustments establish movement but not the reason for the adjustment. Events sharing an effective timestamp use a stable display order, not a claimed processing order.
