What isn't the dev agent's moves to nisse-core, unchanged in behaviour, with its tests: canonical, render, render_anthropic, llm, catalog, probe, context, views, state, reconcile, worker, cancel, dump, transport, matrix, execution, testing, vault, memory, oplog, envfile and gitea (whole). - nisse_core.state.StateStore holds the tables every agent has; an agent's subclass adds its tables (version, migrations), roles and views. nisse_dev.state.StateStore adds the build VM blocks (v5). - views.project takes what each role is shown, rather than a fixed table. - Vault takes the agent's name (agent=), for provenance. - A test that nisse_core never imports an agent. - The loop, config, git, delegation, expert, tools and evals stay in nisse-dev until nisse-ops has a loop to share. Docs: the Development Plan marks M7.1 done and notes that Phase 6 waits on the agent host and Terraform; Architecture Part L names the package.
