Outcome: NOT ESTABLISHED (not answerable from a privileged account)
Evidence: the caller is LoginName "i:0#.f|membership|<account>", Title "Bot 1", IsSiteAdmin=true, and RUNNING_AS_READER is false, so this is an OPERATOR run. IT CANNOT ANSWER THIS AND DID NOT TRY. A trimmed result set and an untrimmed one are IDENTICAL to a caller who can see everything: both return everything that account may see. So a full result set here is not weak evidence that trimming works. It is no evidence at all, and quoting it as reassurance would be worse than leaving the question open. WHAT WOULD ANSWER IT, and it is no longer out of reach: paste this same file while SIGNED IN AS THE REPORTING SERVICE ACCOUNT and set RUNNING_AS_READER = true. That account holds list-scoped Read and nothing else, so whatever comes back to it IS the trimmed view. For the re-run to compare against: S2's STS_List query returned 10 row(s) and S8's STS_Site query 5. Every distinct site/web/path value across both, host redacted, up to 40: ["SPWebUrl=<site>","Path=<site>/Lists/dbmlsp Probe FormatterXML/DispForm.aspx?ID=2","OriginalPath=<site>/Lists/dbmlsp Probe FormatterXML/DispForm.aspx?ID=2","Path=<site>/Lists/dbmlsp Probe FormatterXML/DispForm.aspx?ID=3","OriginalPath=<site>/Lists/dbmlsp Probe FormatterXML/DispForm.aspx?ID=3","Path=<site>/Lists/dbmlsp Probe FormatterXML/DispForm.aspx?ID=1","OriginalPath=<site>/Lists/dbmlsp Probe FormatterXML/DispForm.aspx?ID=1","Path=<site>/Lists/dbmlsp Probe Chain clfpjo/DispForm.aspx?ID=17","OriginalPath=<site>/Lists/dbmlsp Probe Chain clfpjo/DispForm.aspx?ID=17","Path=<site>/Lists/dbmlsp Probe Chain clfpjo/DispForm.aspx?ID=15","OriginalPath=<site>/Lists/dbmlsp Probe Chain clfpjo/DispForm.aspx?ID=15","Path=<site>/Lists/dbmlsp Probe Chain clfpjo/DispForm.aspx?ID=11","OriginalPath=<site>/Lists/dbmlsp Probe Chain clfpjo/DispForm.aspx?ID=11","Path=<site>/Lists/dbmlsp Probe Chain clfpjo/DispForm.aspx?ID=1","OriginalPath=<site>/Lists/dbmlsp Probe Chain clfpjo/DispForm.aspx?ID=1","Path=<site>/Lists/dbmlsp Probe Chain clfpjo/DispForm.aspx?ID=14","OriginalPath=<site>/Lists/dbmlsp Probe Chain clfpjo/DispForm.aspx?ID=14","Path=<site>/Lists/dbmlsp Probe Chain clfpjo/DispForm.aspx?ID=16","OriginalPath=<site>/Lists/dbmlsp Probe Chain clfpjo/DispForm.aspx?ID=16","Path=<site>/Lists/dbmlsp Probe Chain clfpjo/DispForm.aspx?ID=13","OriginalPath=<site>/Lists/dbmlsp Probe Chain clfpjo/DispForm.aspx?ID=13","Path=<site>","OriginalPath=<site>","SPWebUrl=<tenant>","Path=<tenant>","OriginalPath=<tenant>","Path=<sharepoint-url>","OriginalPath=<sharepoint-url>","SPWebUrl=<tenant>/sites/allcompany","Path=<tenant>/sites/allcompany","OriginalPath=<tenant>/sites/allcompany","SPWebUrl=<tenant>/sites/Shaun","Path=<tenant>/sites/Shaun","OriginalPath=<tenant>/sites/Shaun"]
