Purpose of change

Move the resource-lookup-only test factory out of the production ResourceContext API. Java tests now call TestResourceContexts.fromGetResource() from the API test-jar.

Runtime flow and key decisions

Production resource lookup is unchanged. The test factory returns a ResourceContext that delegates getResource to the supplied function and supplies empty skill defaults. Integration modules and integration E2E tests depend on the API test-jar with test scope, keeping the fixture out of production artifacts.

Behavioral Semantics

• The lookup function receives the same resource name/type and its return value is unchanged.
• Skill prompt, directories and source resolution retain their empty defaults.
• Lookup failures propagate unchanged; no retry, fallback or exception conversion is added.
• Interaction decisions: not applicable; this is a factory relocation without a new runtime execution path.

Tests

JDK 21: SKIP_SPOTLESS_CHECK=true bash tools/build.sh -j passed (full clean install, with tests compiled). The 46 migrated test classes completed with 696 passed, 42 skipped, no failures/errors. JDK 11 full-reactor Spotless check and git diff --check passed.

Contract	Evidence
Existing resource lookup and failure behavior	Migrated plan and integration tests use the same lookup functions and assertions.
Empty skill defaults	Factory body preserved; no new dedicated defaults test.
All Java consumers compile against the test fixture	Full Java clean build, including integration E2E test compilation.
Fixture remains test-scoped	Test-jar dependency scopes and production/test JAR contents checked.

Not verified: live model/vector-store services, E2E execution, or Python tests. No Python code changes.

API

Removes the public static Java method ResourceContext.fromGetResource. In-repository callers are tests and move to TestResourceContexts; external callers of the removed convenience method must implement ResourceContext themselves (or use the test fixture in their tests). The remaining ResourceContext methods and production lookup behavior are unchanged.
