What

Two new validator objects were added for telemetry events: one for prompt.edit and one for prompt.attachment. Each includes functions to restore, check, and measure recorded arguments, such as origin, key, text, cursor position, input text, and attachment text, verifying that replayed telemetry data is well-formed before comparing recorded values against live ones.

Why

This strengthens the internal telemetry system's ability to catch malformed or unexpected data when comparing recorded prompt-edit and prompt-attachment events against what actually happened.
