What this check can prove
Classify WebAuthn DOMException names and return likely causes plus the next discriminating checks. Input stays in this browser. The result is a static heuristic review, not a live browser, database, payment, security, or server configuration test. A missing signal means “not shown in the pasted text,” not necessarily “missing in production.”
How to use the result
- Paste the smallest relevant, redacted sample.
- Fix definite syntax or requirement failures first.
- Verify unknowns in the real environment and add a regression test.
