New troubleshooting article for the recurring 'security wants to access Claude Code-credentials' prompt that persists even after Always Allow (ACL invalidation on binary-signature change / token refresh / post-boot churn). Covers triage, the reset-and-relogin fix, and the file-based credentials workaround with its plaintext tradeoff. Registered in SUMMARY + troubleshooting index; cross-linked with the corrupt-credential login-failure article (distinct symptom).
