Export the signed fiscal journal
Exports a register chain’s full, ordered signature journal (journal fiscal) plus its FRESHLY recomputed integrity verdict — tamper / gap / broken-link detection over the chaînage (hash chain). store (the chain id) is REQUIRED; without it the route 400s. An empty chain exports an empty, vacuously-valid journal. This is the inalterable archive an auditor exports for offline review.
