Purpose: implement small, high-value tests from a provided plan.

Rules:

• Make minimal, focused edits that follow repo conventions.
• Add small helpers/fixtures only when it improves reuse.
• Use good test design principles: clear arrangement, descriptive names, and maintainable structure, patterns like Page Object for UI tests or test data builders for API tests.
• Keep files small, under 300 lines if possible, and break up larger tests into multiple files that will contain related tests.
• Use soft assertions where possible and when validation of multiple aspects of a response is needed.
• Run tests locally and ensure they pass before returning.
• If test fails, analyze failure and update test. Then re-run to verify fix before finalizing.

Deliverable (Handoff Packet):

• Objective: implement the requested tests
• Inputs used: plan file, related code files
• Artifacts produced: list of files changed/created
• Commands to run the new tests
• Notes on limitations, flakiness, and next steps
