purview-eventsourcing

Use when designing or refining event-sourced aggregates, commands, events, invariants, source-generator hooks, or snapshot-queryable mirror properties.

Use when defining event-sourced aggregate validation at command time, hook time, save time, or for computed snapshot/query mirror properties.

Use when modeling scalar, complex, or contextual value objects with source-generated normalization, validation, Hydrate/Create semantics, or query-translation awareness.

Create and apply a prerelease bump using Changesets CLI, with the new changeset markdown summarizing the actual changes since the last shipped release.

Use .NET with TUnit-specific test conventions.

Git workflow and conventional commit guidance.

Lefthook Git hook integration.

Run, filter, and select TUnit tests through `dotnet test`. Use this whenever executing .NET tests in a project that depends on TUnit (built on Microsoft.Testing.Platform / MTP, not VSTest), when `dotnet test --filter` reports "Zero tests ran", or when tests must be narrowed by assembly, namespace, class, test name, [Category], or other custom properties. Covers the `--treenode-filter` path-based query syntax, its operators, the `--` separator rules across SDK versions, and common 0-tests troubleshooting.
