mesh-lab/test/integration/assigned-tools-confluence.test.ts

/**
 * The mesh assigns confluence — a tools-only, outbound-only external-SaaS integration
 * (novox/hq ADR 0039), the shape gitlab proved — and its runtime comes up and serves the module's
 * full tool surface, with NO valid Confluence credentials.
 *
 * confluence is the thinnest converted shape: no service container, no listener, no provisioner —
 * only a broker-bound runtime that serves the module's Confluence tools under a scoped account
 * (ADR 0047). The sharp point (the Servarr lesson) is that the runtime MUST register and serve every
 * tool even though the lab has no real Confluence and confluence's own token is a mesh-minted
 * own-secret pointing at nothing. confluence's client is built lazily and never throws at
 * registration, so:
 *   - the mesh-runtime-confluence container comes up and STAYS up (no crash on a missing token);
 *   - it logs `[mesh-tools] serving 3 tool(s)` — the install proof;
 *   - it binds its serve queues on the broker (e.g. serve.confluence.confluence_search), so the tools
 *     are actually reachable, not merely loaded;
 *   - it got its own scoped broker account (anchor-confluence).
 * A tool would only fail if it were actually invoked without real creds — which this bed does not do,
 * because the point is exactly that serving does not require them.
 *
 *   MESH_LAB_HOST_BINARY=.../mesh-host   MESH_LAB_BUNDLE=.../examples/substrate-first-node.lock
 *   scripts/build-module-runtime.sh confluence builds mesh-runtime-confluence:development into the
 *   local daemon; scenarios/tools-confluence.yml stocks it. There is no service image.
