Version 0.16.0

Features

Lager MCP server — a Model Context Protocol server now runs on the Lager Box on port 8100 (FastMCP, streamable-http), allowing AI agents to discover a bench and understand how its nets are wired to the DUT. The server has moved from the CLI to the box and is started automatically inside the Docker container.
Net metadata — nets now support description, dut_connection, test_hints, and tags fields. New lager nets CLI commands and TUI flows let you edit this metadata interactively so AI agents (and humans) can reason about what each net is for.
Capability graph and heuristic engine — a new engine maps test types to the nets available on a bench, giving agents a principled way to pick the right instrument for a given task.
Auto-generated MCP API reference — the MCP API reference is now generated from driver introspection at Docker image build time. The build fails fast if a driver is renamed, so the agent-facing surface stays in sync with the code.

Every MCP tool call is wired through an @audited decorator that records the call via audit.log_tool_call, giving control planes (Stout) a consistent audit trail.
quick_io writes now pass through a preflight_check that enforces voltage, current, and dangerous-action constraints before touching hardware.
The bench.json parser is now defensive: a single malformed entry no longer breaks discover_bench.
MCP errors no longer return raw tracebacks to agents. NetType() inputs are validated against the enum.
plan_firmware_test uses a regex-based pattern split instead of the previous unsafe get_pattern split.
New integration test test_agent_loop plus unit tests for the bench loader, capability graph, heuristic engine, safety preflight, and MCP schemas.

The run_lager MCP passthrough tool is now gated behind the LAGER_MCP_ALLOW_RUN_LAGER environment flag and is off by default. Operators must opt in explicitly before agents can invoke arbitrary lager commands on a box.
