A process-lifetime Capstan.CheckpointStore reference implementation.
Backed by an Agent holding one pipeline's gtid_set string (nil until first
written). It is durable only for the life of the process — a restart loses the
checkpoint — so it is intended for tests and ephemeral pipelines, never as a
production durable store.
Summary
