HasData seeds an entity with a store-generated key but no explicit value. Give every seed row a stable non-zero Id, or switch to UseSeeding for generated keys.

Wire the Agent Governance Toolkit into a Microsoft Agent Framework 1.0 agent so every tool call is checked against a YAML policy and written to a tamper-evident audit trail. Full C# middleware, policy file, and a hash-chained audit sink.

Cursor 3.9 ships a plugin system and a unified Customize page so skills, rules, MCP servers, commands, and hooks travel together as one versioned unit.

The ! operator hit a null at runtime. Replace it with ?. and ?? for a safe default, or guard with an explicit null check, instead of asserting a value that was not there.

Extension properties land in C# 14 through the new extension block. Declare get-only, settable, static, and generic extension properties, why auto-properties are rejected, and how the compiler lowers them to get_/set_ accessors.
