Ergon

Maintain a small, durable work graph across agent sessions. Ergon owns its task semantics in task-protocol.json, listed in manifest.json. Ledger supplies transactions, replay, and projections. There is no separate tracker, wrapper CLI, or agent-maintained readiness cache.

Use when explicitly invoked or when the request calls for maintaining or querying a durable task graph, such as tracking task prerequisites or finding ready and blocked tasks. Do not turn ordinary coding into mandatory bookkeeping, migrate existing tasks implicitly, or change $plan/$actuating routing. Work against the caller-selected repository, not a guessed location.
