-//! Tests proving that multi-tenant system prompts are broken.
-//!
-//! Bug: In multi-tenant mode, the agent loop uses `self.workspace()` which
-//! returns a single shared workspace (user_id="default"). Identity files
-//! (IDENTITY.md, SOUL.md, USER.md) seeded under per-user IDs ("alice",
-//! "bob") are invisible to this workspace, so the system prompt is
-//! empty/wrong.
-//!
-//! These tests:
-//! 1. Seed identity files for two users (alice, bob) in the database
-//! 2. Send messages as each user
-//! 3. Verify the system prompt in captured LLM requests contains the
-//!    correct user's identity
-//! 4. Verify user A's identity doesn't leak into user B's prompt
-//!
-//! All tests are expected to FAIL until the bug is fixed.
