- .NET 10 solution with Core, Connectivity, Rules, Contracts, Agent, Web and Hub - Capability model gating collectors and rules by SQL Server version (2000 and later); rules that cannot run are reported as not measurable, never as passed - Connectivity via Microsoft.Data.SqlClient with ODBC fallback for legacy instances, hardened monitoring session settings valid back to SQL Server 2000 - Support lifecycle rule (SQLI-VER-001) with lifecycle data shipped as a rule pack - Version-aware least-privilege permissions script, verified by integration tests against SQL Server in Docker (reads monitoring sources, cannot read customer data) - Forgejo Actions CI, contributing guide, code of conduct, issue templates, legacy version notes Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01E3EExwndy8Z22EK2Qpt6BK
