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 acquired upon the vesting of restricted stock units (RSUs) granted to the Reporting Person on February 3, 2022. Restricted stock units convert into common stock on a one-for-one basis. Sale made by the Reporting Person to satisfy tax withholding obligations in connection with the partial vesting of RSUs granted on February 3, 2022. The RSUs vest in four equal annual installments beginning on February 3, 2023, such that the RSUs fully vest on February 3, 2026. The RSUs are subject to accelerated vesting upon termination without cause upon a change of control of the Issuer.
Raspberry interpretation
Informational — no alert
Reason: tax_withholding. The filing footnotes identify tax withholding.

Voluntary purchases and sales; administrative noise stays hidden.
