C-2 follow-up: sanitize_stored_content_type previously let a CRLF pass
through an allowlisted prefix (e.g. "image/png\r\nX-Injected: 1" matched
the image/ branch and returned the original), which would inject a
response header / panic HeaderValue on download. Now any control byte
(<0x20 or 0x7f) coerces to application/octet-stream up front.
F-SE-H-03: disable_symbol("debug") to match "print" (the comment
already claimed both were disabled) so scripts can't write
attacker-controlled bytes to the operator's stderr.
