MODIFIED Requirements

Requirement: Test migration design SHALL preserve safety behavior

The project SHALL replace Sequential/Hook implementation tests with authoritative DiagnosisGraphWorkflowTest, DiagnosisGraphNodeContractTest, and ChatServiceGraphIntegrationTest layers while retaining focused public/security contract tests. Fixed Agent call order and legacy Hook payload shape SHALL NOT remain correctness criteria.

Scenario: Old tests are replaced

• WHEN StateGraph tests become authoritative
• THEN ChatServiceSequentialAgentTest SHALL NOT exist
• AND VerifierInputHookTest SHALL NOT exist after explicit Gatekeeper/Verified Input coverage is established
• AND no replacement test SHALL restore fixed Sequential Agent order as a public requirement

Scenario: Safety tests are retained

• WHEN the new suite is assembled
• THEN Gatekeeper, Controller, Run/Trace, Repository, Composer, parser/projection, no-evidence, REJECT, Eval, and multi-run safety contracts SHALL remain covered
• AND Workflow and Node Contract matrices SHALL cover bounded retry, fail-closed routing, verified-only inputs, and deterministic Fallback

Scenario: Authoritative test layers are inspected

• WHEN a maintainer needs to locate ISS-011 orchestration verification
• THEN Workflow tests SHALL own route/loop/event behavior
• AND Node Contract tests SHALL own input/output/security projection behavior
• AND Chat integration tests SHALL own Run lifecycle and public result behavior
