Error message

message should deserialize

What it means

A test-only expect("message should deserialize") panic: serde_json failed to parse the just-serialized JSON back into a Message. The test guards that an InterruptedAssistant message round-trips as a distinct session item; failure means the serialized form (role tag or content shape) is not accepted on the way back, so interrupted turns would be lost or coerced on reload.

Solutions

1. Diff the serialized JSON against what Deserialize expects for Role::InterruptedAssistant
2. Align the serde attributes (tag, rename, content) so the serialized form parses back
3. Cover the full content-block set in the round-trip test to catch asymmetry early
