Implementation blueprint from spike experiments — SEP-2640 Skills support AND the schema-server toolkit lift (config-driven MCP servers for SQL / GraphQL / OpenAPI backends). Requirements, proven patterns, multi-dialect SQL connector trait, two-axis Skills (Type 1 build-time vs Type 2 runtime SEP-2640), and the dual-surface invariant. Auto-loaded during implementation work.
