Confirmed by evidence rather than suspicion: no XSD governs SAF-Site-Manifest.xml. No manifest schema exists among the SAF schemas and the file carries no schemaLocation. The file that defines every servable site in the platform - 35 blueprints, their lists, permissions and feature bindings - is validated by nothing, so any misspelled element or invented attribute is accepted in silence. Duplicate of SPF.5 on the fidelity backlog; keep them linked rather than merged, because this row carries the evidence and that one carries the survey ranking.
