Testing foundation before stabilization bug fixes

[alx-so]

Goal

Create a meaningful test baseline before starting production fixes for the current stabilization bugs.

The project already has Jest and CI configured, but the current test suite only contains a placeholder. This tracking issue organizes the testing foundation into small, reviewable tasks that should be completed before or as the first part of the stabilization milestone.

Testing-first task order

• Make local and CI test commands reproducible before bug fixes #9 Make local and CI test commands reproducible before bug fixes
• Replace placeholder Jest test with baseline utility coverage #10 Replace placeholder Jest test with baseline utility coverage
• Add component smoke tests for public library exports #11 Add component smoke tests for public library exports
• Add regression-test requirements to stabilization bug fixes #12 Add regression-test requirements to stabilization bug fixes

Stabilization bugs this should unblock

• Search results use stale item data after items prop changes #3 Search results use stale item data after items prop changes
• Multiple mode can pass string arrays to TextInput value #4 Multiple mode can pass string arrays to TextInput value
• Select and InputSelect ignore controlled value prop updates #5 Select and InputSelect ignore controlled value prop updates
• Freeform and default tags can receive duplicate IDs #6 Freeform and default tags can receive duplicate IDs
• Build config excludes wrong example folder and test suite has no coverage #7 Build config excludes wrong example folder and test suite has no coverage
• Wire or remove declared public props that are currently no-op #8 Wire or remove declared public props that are currently no-op

Acceptance criteria

• The placeholder-only test suite is replaced with meaningful baseline coverage.
• Safe validation commands are documented and aligned with CI.
• Public exports have at least smoke coverage.
• Known stabilization bug fixes include regression tests where practical.
• No app server, Metro server, browser, or long-running process is required to run the baseline test suite.
