A DBA should be able to review every statement SQLInsight sends to a monitored server before granting it access. "SQL Scripts/<rule-id>.sql" holds, per rule (82 built-in, 16 community), a Danish header (what and why, how C# judges the data, thresholds with config keys, severity, exact GRANTs, versions, collector file and member) and the collector's SQL verbatim, every version variant as its own batch. "_collectors/<Collector>.sql" holds each collector's queries once. The only statement that is not strictly read-only is documented in the scripts: the deadlock collector's session temp table (#system_health). Inline SQL in the collectors moved to internal constants and Build*Sql methods (no text changed), so SqlScriptTests can check that the scripts still contain the SQL the code sends, that every rule has a script, that every collector query is registered, and that nothing writes.
