EXP-11 · Baseline
This page has no exotic HTTP headers, no canonical directives pointing elsewhere, and no referenced resources with deindex directives. It is the control for the experiment: a boring, normal page in the same directory tree.
Unique fingerprint string: genbox-exp11-baseline-control-0e11.
If the baseline indexes normally while probe pages exhibit anomalous canonical or index states, we have isolated the HTTP-header behavior as the cause.
