New NaturalKeyAggregateAttribute emitted by the source generator when a self-aggregating type has a [NaturalKey] property. This allows Marten to auto-register the snapshot projection and natural key infrastructure at startup without requiring explicit Projections.Snapshot<T>(Inline) calls. - AggregateAnalyzer: detect [NaturalKey] properties on aggregate types - EvolverCodeEmitter: emit [assembly: NaturalKeyAggregate(typeof(T))] - NaturalKeyAggregateAttribute: assembly-level marker for discovery Fixes JasperFx/marten#4199 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- JasperFx 1.21.4 → 1.21.5 - JasperFx.Events 1.24.1 → 1.24.2 (new NaturalKeyAggregateAttribute) - JasperFx.Events.SourceGenerator 1.3.0 → 1.4.0 (natural key discovery) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
