| """Shared pytest fixtures for the sibyl-memory-client test suite. |
| |
| Two hermeticity guarantees: |
| |
| 1. **Canonical source import.** This repo is the canonical source tree for |
| the published package. Prepend ``src/`` to ``sys.path`` so the suite |
| always exercises THIS tree, even on machines where an (older) editable |
| install of ``sibyl_memory_client`` resolves to a different checkout. |
| |
| 2. **Home/env isolation** (``_isolate_home``, autouse). The account-level |
| cap aggregation (``aggregate_db_size``, 0.4.18) walks real filesystem |
| locations — ``~/.sibyl-memory/memory.db``, ``$HERMES_HOME/sibyl/...``, |
| and ``$SIBYL_MEMORY_DB`` — to sum every store an agent resolves. Without |
| isolation, a developer's real local memory store would leak into the |
| aggregate and skew (or spuriously trip) the cap in tests. Every test |
| therefore gets HOME/USERPROFILE/HERMES_HOME pointed at a private tmp dir |
| and SIBYL_MEMORY_DB removed, keeping the aggregate-cap tests hermetic. |
