輸出（由工具此刻实时生成）
Self-test: FAILED
rendered 264×264px, decoded back and compared to the original payload
decoded ≠ original ✗ ("No QR code detected in this image.")
Checks
Quiet zone 4 module(s) ✓
Contrast 21.00:1 ✓
Logo coverage 0% ✓
Symbol size version 2, 25×25 modules
Output size 264×264 px
Payload 25 bytes / 2331 max at EC M
Verdict: RISK — self-decode failed
This is a rendering self-test, not a guarantee: it proves the generated matrix
decodes correctly, but real-world scanning also depends on print quality,
lighting, focus and the scanner app.
此输出由工具真实运行产生，并非人工编写。
