…th tests A blank or whitespace X-HWID is what some clients send when device ID is off. The new validator turned it into a 400 on every subscription route, even with HWID disabled; it now counts as no header again. Oversized values and control characters are still rejected. Tests: blank and oversized X-HWID, long device info headers (clipped to the user_hwids column sizes by the crud), four concurrent registrations against a limit of 1 on independent connections, no proxy_settings in /info and /raw, and the /raw manual-sub HWID gate.

Reject C1 control characters in HWIDs.
If X-HWID contains device\x85one, this check accepts U+0085 because its code point exceeds 127. Registration can then store a control character in the HWID. Reject the Unicode Cc category as well as the controls already covered, and add a test with an embedded C1 character. HTTP permits the relevant header octet, and Unicode classifies U+0085 as a control character. (rfc-editor.org)

Header bytes arrive decoded as latin-1, so 0x80-0x9f reach the validator as C1 controls (for example U+0085), and the check only covered C0 and DEL. Reject every character in Unicode category Cc and test C0, DEL and C1 bytes.
