sentarion-mcp (v0.1.0)

Composite MCP server wrapping Algernon (fan-out orchestration) and ArkHive (governed audit/memory). Connects to both as an MCP client — does not reimplement either.

What's real right now

• cost_estimate — pre-dispatch cost prediction, grounded in Algernon's own published benchmark numbers.
• dispatch_with_dependencies — fan-out/fan-in wave ordering on top of Algernon's independent-task algernon_dispatch.
• orchestrate_and_record — plan+dispatch, auto-logged to ArkHive's remember.
• recall_and_replan — pulls ArkHive recall history into a new Algernon plan.

Governance — real, wired, fail-closed

govern_stub.py now carries the REAL ArkHive govern client (verified against the live GovernanceBlock engine, 2026-08-18):

• wire in: {action, flags: [...], rules: [{trigger, action}]}
• wire out: {vetoed: bool, reason, engine: "zero-LLM rule gate", auditable: true}
• verdicts are binary (no "pending" state exists in the engine)
• fail-closed: if ArkHive is unreachable, dispatch is blocked — an absent governor never silently approves
• a blocked orchestrate_and_record returns the decision and skips dispatch

Not yet built (deferred, per the earlier feature list)

• Durable/crash-resistant execution via mcp-agent (Temporal-backed) — listed as a dependency in pyproject.toml but not yet wired into server.py.
• Phase-gate state machine (queue→work→review→terminal) inside ArkHive's govern — depends on #1 above.
