The probe endpoint and the source scanner injected the prebuffer/detect markers with a stray backslash in the header field-name (`X-\XC_VM-Prebuffer` / `X-\XC_VM-Detect`), a leftover from the namespace migration. A backslash is not a valid HTTP token character, so strict origins/CDNs (e.g. Akamai) answer 400 Bad Request and the probe fails silently (ffprobe runs with `-v quiet`), breaking Load Maps and stream checks for otherwise-valid sources. Use the correct `X-XC_VM-Prebuffer` / `X-XC_VM-Detect` names, matching what StreamProcess sends and what auth.php/live.php read back.
