# Custodian Agent Runtime — Bootstrap

## Summary

Design and bootstrap the Custodian as an acting agent: a standalone
LLM-powered service that uses the State Hub as its coordination layer.
Distinct from the State Hub tooling itself.

## Context

The State Hub provides the read model and MCP interface. The Agent Runtime
is a separate concern: the loop, policy engine, and tool adapters that
make the Custodian an autonomous (or semi-autonomous) participant rather
than a passive data store.

## Dependencies

Both dependencies resolved and removed from the dependency graph (2026-03-11):

- ~~`markitect/llm-shared-library` (llm-connect)~~ — resolved 2026-02-27:
  llm-connect extracted as standalone installable package and integrated.
- ~~`railiance/phase-0-operational-baseline`~~ — resolved 2026-03-11:
  Railiance01 operational with k3s + HA failover tested + backup verified
  (RAIL-BS-WP-0002, RAIL-BS-WP-0003, RAIL-BS-WP-0004 all completed).

**This workstream is unblocked. T2 is ready to execute.**

## Tasks

### T1 — Bootstrap blocked: awaiting markitect/llm-shared-library

```task
id: CUST-WP-0001-T01
state_hub_task_id: ac42e548-10bf-4851-94e2-c8d35876f2f9
status: done
priority: high
```

All implementation tasks for the agent runtime were blocked until
llm-connect was extracted as a standalone installable package from
markitect. Resolved 2026-02-27: llm-connect integrated in state-hub as
editable dependency; markitect llm-check smoke test green.

### T2 — Define agent architecture and capability scope

```task
id: CUST-WP-0001-T02
state_hub_task_id: 9a9297cd-bd3c-409c-8384-6f06cfc6faa2
status: done
priority: medium
```

Decide the Custodian agent's primary loop: what is the core OODA cycle?
What tools does it need beyond the State Hub MCP? Where does it live —
new repo or `runtime/` in the-custodian? Produce an architecture sketch
covering: entry point, LLM integration (via llm-connect), tool manifest,
state-hub interaction pattern, and deployment target.
