Capture the current entrypoint once without inventing a path. Preserve unknown registration ownership through setup and doctor, refuse unsafe registration plans, and retain exact pinned-launcher readiness checks. Hash the same full or compact schema projection advertised by each MCP server and use that identity in doctor comparisons.
BREAKING CHANGE: server.command_path may be null when the invocation path is unavailable. Registration and setup statuses, and doctor classifications, may report unknown.

Keep lazy cached catalog calculation internal; publish catalog counts and digests as plain data. This repairs binary_session and doctor output after inert JSON validation.
Validation: production stdio MCP doctor and invalid-probe controls pass; build, static and docs checks pass.
