Use compact MCP input advertisements by default while preserving explicit full, canonical validation, output contracts and complete Evidence. Require an explicit selected catalog for runtime identity and honor both profiles in CLI status.
Real ripgrep/Zellij SDK tasks, independent ELF oracle, actual client trials, profile parity workflows and CI are recorded in experiments/analysis-efficiency/mcp-input-catalog.md. SDK token estimates improve; actual Codex token savings and general latency/memory gains are not established.

BREAKING CHANGE: MCP input advertisements default to compact. Set REA_MCP_INPUT_SCHEMA_PROFILE=full for complete advertised guidance and nested constraints.
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.
