• Upgrade rays to v0.3.0

• Add Stream[T] as an allowed return type

• Update Build() prefix matching to accept Stream prefixes (e.g., StreamAllByName) in addition to Find, Query, and List

• Query(), queries returning Stream[T] execute the GORM query and return a populated Stream[T]{}.FromSlice(t) (or empty stream with error if an Error return parameter is specified)

• Update return types and supported method prefixes to document Stream[T] and the Stream prefix

• Add tests verifying :

  • Finding records returning Stream[User] and transforming them via .Filter(...), .SortedBy(...), .Map(...), and .ToSlice().
  • Using Stream method prefix (e.g., StreamAllByName).
  • Error handling with (Stream[User], Error).
  • Rejection of invalid Stream element types during container initialization.

Summary by CodeRabbit

• New Features
  • Repository queries can now return matching records as streams, including methods using the Stream prefix.
  • Stream results support filtering, sorting, mapping, and counting, and can report errors when applicable.
• Documentation
  • Updated query-method guidance to include list, List, stream, and Stream prefixes.
  • Clarified that multiple-entity results may use []T or Stream[T].

Walkthrough

The query builder now accepts stream-prefixed repository methods that return Stream[T]. It executes Find, converts the resulting slice into a stream, and returns it. Repository tests and documentation cover the added return type and method prefixes.

Changes: Stream query support

Layer / File(s)	Summary
Declare and validate stream queries go.mod, pkg/core/core_suite_test.go, pkg/core/query_builder.go, docs/content/docs/3-repositories.md	The rays dependency is upgraded to v0.3.0. The query builder accepts the Stream prefix and Stream[T] return type. Repository examples and documentation include stream query methods and return types.
Build and test stream results pkg/core/query_builder.go, pkg/core/core_suite_test.go	The query builder uses Find for stream outputs and converts the result slice with Stream[T]{}.FromSlice. Tests cover stream operations, error-returning queries, and a mismatched stream element type.

Merge Risk: Minimal · up to b3603

No merge-blocking defect was identified. A failing-query test would strengthen error-handling coverage.

Security architecture risk: Low · up to b3603

The new return type follows the existing database query path and preserves its predicates, scopes, transaction source, and entity-type checks. No new security boundary bypass was identified. Remaining uncertainty concerns the broader dependency upgrade and behavior not verified at runtime.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The new result form operates with the existing repository model and transaction authority. Its exposure is inherited from the consuming application's database access and scopes; this library change does not establish a new tenant, service, or datastore boundary.

Trust Boundaries and Controls

• observed — Exact Stream[T] validation preserves entity-type isolation, and the Stream branch retains the same predicates and caller-supplied scopes as the existing collection branch. The mismatched Stream[Foo] fixture remains unset during repository initialization.

Resilience and Maintainability Implications

• inferred — Because Find completes before stream adaptation and FromSlice receives only loaded values, this path does not transfer database cursor or transaction ownership to stream consumers. It retains eager collection materialization rather than introducing a deferred database lifecycle requiring new cancellation or cleanup rules.

Exercise a failing GORM query in the Stream/Error test.

"NonExistent" is a successful query with zero rows. It does not exercise GORM error propagation. A regression that drops res.Error would pass the current test.

Suggested fix

 	It("can return a Stream with Error", func() {
 		st, err := userRepository.FindStreamWithErrorByName("Dorothy")
 		Expect(err).NotTo(HaveOccurred())
 		Expect(st.Count()).To(BeNumerically("==", 1))

 		stEmpty, err := userRepository.FindStreamWithErrorByName("NonExistent")
 		Expect(err).NotTo(HaveOccurred())
 		Expect(stEmpty.Count()).To(BeNumerically("==", 0))
 	})
+
+	It("returns a GORM error and an empty Stream when the query fails", func() {
+		Expect(userRepository.Query().Migrator().DropTable(&User{})).To(Succeed())
+
+		st, err := userRepository.FindStreamWithErrorByName("Dorothy")
+		Expect(err).To(HaveOccurred())
+		Expect(st.Count()).To(BeNumerically("==", 0))
