Input

Evaluate the exact packaged stringify and parse expressions with devalue 6.0.2 on synthetic objects, script delimiters, Dates, Maps, Sets, undefined, shared/cyclic references and rejected function/symbol values. Use no actual application state or account.

Acceptance criteria

Eight supported-value round trips match with no literal less-than character in serialized strings; function and symbol inputs are rejected. This covers expression behavior only, not a Pinia/Vue runtime, SSR server, CSP, HTML embedding implementation, browser hydration or full skill.

Recorded outcome

Ten synthetic assertions for the exact packaged stringify/parse expressions only. This does not execute Pinia, Vue, an SSR server, a browser hydration flow, HTML transport, CSP or a full agent workflow. Escaping observation is limited to the serialized string, not a complete HTML embedding implementation.
