Corrections
- 29 Jul 2026
- During data capture from photographs of sample **9gsfxvk**, the crimp color was incorrectly recorded as **Golden** instead of **Silver**. Verification against the corresponding Certificate of Analysis (COA) confirmed that the correct crimp color is **Silver**. The record has been updated to reflect the information provided in the COA.
