FN-8764 made AgentStore.init() unconditionally provision the four durable
built-in workflow-owner agents, and that provisioning needs a bound
asyncLayer.projectId — backendProjectId rejects the empty/unbound partition so a
shared cluster cannot mix ownership. Every AgentStore-backed PG test therefore
threw in init(); without this change all 10 cases in agent-instructions.pg.test
fail at agent-store.ts:526.
createTaskStoreForTest / createSharedPgTaskStoreTestHarness gain an OPT-IN
projectId. Undefined keeps the historical project-agnostic harness (RLS bypass,
empty-string partition) that the rest of the core suite relies on. When set, the
connection GUC `fusion.project_id`, the AsyncDataLayer, and the seeded config row
all share one partition — so agents (explicit project_id) and their config
revisions (GUC-default project_id) land together and the
(project_id, agent_id) FK on agent_config_revisions holds.
Also folds in two already-merged consequences: serve.test expects the
consumerId: "engine" that serve.ts:326 already passes (FN-8685), and the
auto-generated Fusion skill docs pick up fn_workflow_step_resume, the roles /
max_workflow_sessions agent fields, and the deprecated singular role.
Uncommitted in the working tree; reviewed, verified against the real database,
and committed as-is.
