new/exit action sequence, same manager × ticker

• 1. Action filter. Only new and exit actions. Adds and trims don’t count — a true reversal is going to zero and back.
• 2. Comeback. The first event is an exit and a later event is a new. The manager sold it completely, then later opened a fresh position in the same name. Rarest pattern in the archive.
• 3. Whipsaw. The first event is a new and a later event is an exit. The manager opened the position and then walked within the 8-quarter window.
• 4. Gap quarters. Distance between the first and last event in the sequence. Larger gap = more distance between the two decisions.

The archive only covers 8 quarters — reversals that span longer windows are not visible yet. As more quarters land, the comeback count will grow.
