 [2026-08-01] Out-of-order SIE IB activity is bounded by the target fiscal-period end, not its start: this excludes later-first imports while preserving same-period continuation suppression; successor IB resync checks the current error state plus a real target-period entry because result.success is finalized later, keeping replacement on a new engine voucher plus storno without letting a no-op import succeed through resync alone.
 [2026-08-01] Successor SIE IB replacement uses a specialized engine RPC instead of loosening the owner-only generic relink RPC: non-viewer members and scoped service-role imports are supported, while one period-row lock and expected-pointer CAS make the replacement voucher, storno, reversal status, pointer swap, and voucher sequence increments commit or roll back together.
 [2026-08-02] Out-of-order SIE IB resync requires exact date adjacency: the nearest later fiscal period can sit beyond a missing middle year, and replacing its authoritative IB with a non-adjacent UB would make that later period temporarily wrong until the gap was imported.
+[2026-08-03] Issue #1360 keeps EUR annual reports fail-closed at general eligibility rather than only digital filing: the ledger and annual-report model are SEK-denominated, so allowing a EUR profile to lock a paper version would mislabel SEK amounts; full EUR support requires a company accounting-currency model across the ledger, report builders, and iXBRL.
 [2026-08-03] Issue #1267 localizes the latest-posted-voucher label in the web views while PDF and spreadsheet exports remain Swedish: translating one export label would create mixed-language files, so full export localization stays a separate surface-wide change.
