/**
 * Participant drift alerts for the recognition path — the TS mirror of the
 * oracle's `core.drift_context` + the alert-reading half of
 * `core.participant_watermark`.
 *
 * A participant that can still OPEN its native store but no longer PARSE it
 * yields nothing while every presence check stays green. The export path
 * persists a per-participant watermark verdict; this module reads those
 * verdicts back and renders the active `drift` ones as bounded
 * `{agent, checked_at, reason}` rows for `prepare_recognition_context`.
 *
 * State is advisory and untrusted: missing, malformed, and unrecognized
 * entries fail open (no alert), and every field is bounded through the
 * redaction SSOT before it can reach a prompt.
