"""Regression test for the v0.1.3 first-use write bug.

Bug (sylvain1550 Discord report 2026-05-27 + QA note run-2026-05-28-mcp-run05;
related to KAPPA's coordination thread): with no credentials.json present,
`_build_client()` passed `tenant_id=creds.get("tenant_id")` == None EXPLICITLY,
overriding MemoryClient.local's DEFAULT_TENANT default. Every write then hit the
`entities.tenant_id NOT NULL` constraint and failed with an opaque
`SQLite error: IntegrityError`, while reads + tool discovery still worked -- so a
broken install looked healthy.

Fix: `tenant_id=creds.get("tenant_id") or DEFAULT_TENANT`. This test fails on the
pre-fix code (IntegrityError) and passes after.
