Representation stability

Temporal retrieval measures whether a first-window profile retrieves the same player in a later window. It measures consistency, not scouting quality. Candidate groups are small; see the random baseline.

Similarity is not quality, tactical fit, transfer success or future performance. One season in one competition cannot establish cross-league comparability.
