Baselines per hour of the week (with neighbouring hours) from four weeks
of hourly aggregates, computed in C# (independent of DATEFIRST) and
refreshed by the agent each hour. SQLI-ANOM-001 compares current load
with what is normal at this time: CPU far above normal, batch requests
far above or collapsed (application down?), page life expectancy
collapse. Not measurable until enough history exists.

- Versioned, embedded migrations serialized with sp_getapplock so the agent
and web UI can both migrate at startup
- Findings tracked per rule and subject: first seen, last seen, resolved;
a rule that could not run never resolves its findings
- Time series (waits, file I/O, CPU, counters), blocking chains and
deadlock graphs; idempotent inserts (timestamps truncated to match
datetime2(0)), hourly aggregation and batched retention deletes
- Read API for the web UI; integration tests against SQL Server
