Direct module-attribute patching of _kg is obsolete after the lazy
cache refactor. Switch test helpers to patch _get_kg instead so the
fixture KG replaces the factory rather than a now-missing singleton.
- tests/test_mcp_server.py: _patch_mcp_server helper
- tests/benchmarks/test_mcp_bench.py: _patch_mcp_config helper
- tests/benchmarks/test_memory_profile.py: inline patch in test_tool_status_repeated_calls
- Run ruff format on all benchmark files (fixes CI lint job)
- Fix check_regression() substring ambiguity: ordered keyword matching
so "latency_improvement_pct" is correctly classified as higher-is-better
- Update stale comments in conftest.py referencing wrong fixture
- Add pytest addopts to skip benchmark/slow/stress markers by default
Benchmark mempalace at configurable scale (1K–100K drawers) to find
real-world performance limits. Tests cover MCP tool OOM thresholds,
ChromaDB query degradation, search recall@k, mining throughput,
knowledge graph concurrency, memory leak detection, palace boost
quantification, and Layer1 unbounded fetch behavior.
- tests/benchmarks/ with 8 test modules + data generator + report system
- Deterministic data factory with planted needles for recall measurement
- JSON report output with regression detection (--bench-report flag)
- CI benchmark job on PRs at small scale
- psutil added as dev dependency for RSS tracking
