/**
 * The drift-detection pipeline for one stack: last-operation event scan →
 * suspect classification → journal merge → probe → journal upkeep. Shared by
 * `fjall drift detect` and the [G2] deploy pre-flight so both surfaces report
 * identical findings for identical state.
 *
 * Journal upkeep: confirmed or unconfirmed findings (the wedge persists or
 * could not be ruled out) re-record the journal so the next deploy re-probes;
 * all-present or stack-missing findings clear it.
