The value is in what we do not call a signal.
The SEC XML stores every transaction. Raspberry keeps that evidence, reads the footnotes and separates voluntary open-market activity from vesting, option exercises, gifts, tax withholding, stock purchase and dividend reinvestment plans and pre-programmed 10b5-1 trades.

Represents shares sold to satisfy tax withholding obligations in connection with the vesting of restricted stock units previously granted to the Reporting Person. This transaction does not represent a discretionary sale by the Reporting Person.
Raspberry interpretation
Informational — no alert
Reason: tax_withholding. The filing footnotes identify tax withholding.
Recent transactions
Voluntary purchases and sales; administrative noise stays hidden.
