Under the hood
System prompt snapshotting now tracks provenance and a hash to detect drift.
The system prompt snapshot mechanism, used to detect and replay system prompt drift, now tags results with a source value of from_snapshot, live_recorded, or live_unrecorded, along with a snapshotHash. It also factors in a hostPrompt fingerprint that accounts for custom or appended system prompts and whether the session is local, remote, or Chrome-launched.
