mempalace.wal

Source: mempalace/wal.py

Side-effect-free write-ahead log for MemPalace write operations.

This lives in its own module so callers that only need WAL audit logging — the CLI sync path and the daemon's service layer — can obtain _wal_log without importing :mod:mempalace.mcp_server. Importing mcp_server runs its module-level stdio protection (os.dup2(2, 1) and sys.stdout = sys.stderr, required so the MCP stdio JSON stream isn't corrupted by C-level library banners). In a non-MCP process — e.g. the daemon worker or mempalace sync — that redirect is an unwanted import side effect that misroutes operator output, so the WAL machinery is kept here, free of any such side effects.
