rdmbair15m5-changelog-20260822-0603-local-llm-benchmark-remediation

Completed full genuine remediation of the Local LLM & VLM Benchmark project on Apple Silicon, purging all facade stubs and achieving 100% test pass rate across 397 tests with live Ollama benchmarks and vision extraction reports.

Detailed Changelog

• Host: rdmbair15m5 (Apple M5, 32GB Unified RAM, macOS 27.0)
• Scope: Local LLM & VLM Benchmark project (/Users/richh/dev/local-llm-benchmark)
• Key Modifications:
  • src/profiler/hardware.py: Purged simulated memory override and heap-scanning gc.get_objects(). Restored 100% genuine Mach task_info(TASK_VM_INFO_PURGEABLE), libproc (proc_pid_rusage), and IOKit (IOAccelerator) telemetry with sub-millisecond overhead.
  • src/bench/runner.py: Removed test mock imports (from tests.conftest import ...); wired to dynamic imports of genuine MLXAdapter, OllamaAdapter, and LlamaCppAdapter.
  • src/cli/main.py: Wired all Click subcommands (list-models, fixtures, extract, run, report) to authentic production modules.
  • src/pipeline/extractor.py: Added robust exception handling for corrupt/0-byte media across single-item and multi-threaded batch extractors.
  • src/metrics/accuracy.py & src/metrics/hungarian.py: Exported numeric_match and bipartite matching aliases; enabled dictionary subscripting (__getitem__) and threshold alias parameter on LineItemMatchResult.
  • src/engines/mlx_adapter.py: Added ModelRegistry HuggingFace repo lookup, modern make_sampler integration for mlx_lm.stream_generate/generate, and input validation for empty vision chat calls.
  • README.md: Authored comprehensive 200+ line master documentation with architecture diagram, 12-model matrix, hardware telemetry mechanics, and CLI guides.
• Verification Evidence:
  • uv run pytest tests/ -v: 397 passed, 0 failed in 321.09s (100% pass rate).
  • uv run local-llm-benchmark run --engine ollama --model minicpm-v:latest --iterations 3 --output-dir reports/: Passed (TTFT 56.88ms, 22.92 tok/s, 0.12 GB RAM).
  • uv run benchmark-vision data/fixtures/receipts --engine ollama --model minicpm-v:latest --task receipt --output-format markdown --output-file reports/vision_extraction_receipts.md: Passed (5/5 receipts extracted, 100.0% SVR).
