+## Accumulated Context
+
+### Recent Decisions
+- Phase 5: Fakturownia client mappings use tax-based keys with legacy id fallback.
+- Phase 5: Proforma documents are skipped by kind and FP prefix.
+- Phase 5: Selected invoice positions can be skipped without creating finance operations.
+- Phase 5: Fakturownia mapping edits are available only for imported operations.
+- Phase 5: Mapping changes can optionally bulk-update matching imported operations.
+
+### Concerns
+- Existing Fakturownia operations identify item mapping from operation description plus mapping fallback. Future importer work should store explicit operation_id -> item_key metadata.
