What lives here

• src/liquidus_mcp/provenance.py — F5 governance-tuple wrapping.
• src/liquidus_mcp/sdk.py — httpx client (v1.2 bearer-tri-state, v1.3 hand-authored-SDK).
• src/liquidus_mcp/server.py — MCP stdio server, 4 tools + wrapping.
• tests/test_provenance.py — F5 shape assertions (unit level).
• FEEDBACK.md — clarity report against v1.3.

Quick start

gmake install
gmake test           # F5 shape unit tests
gmake run            # server on stdio — use from an MCP client

Load-bearing finding

Wrap is NOT idempotent — nested wrapping is intentional (composable provenance). Spec v1.4 should say so explicitly. See FEEDBACK.md §1.1.
