Mar 1, 2026March 2026 (2026-03) monthly summary for nuts-foundation/nuts-knooppunt. Focused on strengthening privacy-preserving data sharing, stabilizing policy evaluation flows, and improving developer experience. Delivered three major feature sets and updated documentation to support production readiness. PDP policy orchestration improvements refactored subject input mapping to introspected tokens, integrated local consent checks via PIP, and resolved an edge-case in PIP input enrichment ordering. E-overdracht policy enhancements introduced sender/receiver rules, extended document operation support, and improved notification routing to support flexible request paths. Documentation updates clarified PDP usage and integration guidance with updated examples and references to config/test scripts.
