These pure functions handle payload storage preparation but lacked verification. - -πŸ“Š **Coverage:** The following scenarios are now tested: -- Happy paths for converting data and tags into serialized JSON strings. -- Edge cases where `tags` are provided as `None`. -- Unicode handling to ensure that `ensure_ascii=False` appropriately works without escaping characters. -- Decoding behavior of valid JSON, invalid JSON formats (catching `json.JSONDecodeError`), and TypeError handling for `_parse_memory_value`. - -✨ **Result:** Test coverage for the core memory data encoding mechanism is significantly improved, preventing potential regressions during memory data restructuring.
