Gap

Lane H (kind:reasoning-graft-candidate) is graph-resident — emitted by the confer-loop downstream — but workers have no hermes-native read surface. Per NousResearch#203 §3.2, a worker requesting a paid-tier reasoning lift should call requestReasoningGraft and read the result via the same tool surface.

What is needed

Add MCP tools:

• requestReasoningGraft(prompt: str, lift_model?: str) — kicks off a Lane H lift via devagentic's confer/lift pipeline. Returns the resulting reasoning-graft-candidate doc id.
• fetchReasoningGraft(graft_id: str) — fetch the lift result for the worker to use as preamble for its next moves.

Acceptance

• Both tools registered under mcp_serve.py.
• Unit test verifying the round-trip: request → graft doc written → fetch returns content.
• Docs explain the lift-and-graft pattern (high-tier model = synthesis; cheap silos = breadth; lifts grafted DOWN as preamble for subsequent calls).

Notes

• Depends on G2 (fetchReasoningGraft is a specialized querySilo read). Could share an MCP module with G2.
