Merge Risk: 🟡 Moderate · up to The modular CLI now preserves package exports, but resume can still reject valid partially covered runs or fail abruptly on malformed records, while help output may omit its description.

objects or calling load_suite and load_environment. Raise the established
PerfMatrixError with clear field-specific diagnostics so invalid or missing
values reach main’s documented status-2 handling, while preserving normal
loading for valid paths.
- Line 108: Persist the run’s allow-partial setting in results.json when
executing the run command, and update resume to read that saved setting and skip
_coverage when partial coverage was allowed. Keep _coverage validation for
resumed runs that did not enable partial coverage.

Make this string the module docstring.
This string appears after executable statements, so Python does not assign it to __doc__. Line 57 therefore gives argparse.ArgumentParser a None description.
Move the string before from __future__ import annotations.

Background
The monolithic
tools/perf_matrix.pyscript (approx 2,743 lines) had become difficult to maintain, optimize, and safely update without causing severe merge conflicts for individual model-family developers. The goal of this change is to modularize the matrix script into a cohesive Python package while keeping backward compatibility intact.Exit Criteria
core.py,types.py, andcli.py).tools/perf_matrix.pycontinue to work without modification (via a newly introduced wrapper script).Implementation
tools/perf_matrix/.types.py.core.py.cli.py.tools/perf_matrix.pyfile with a lightweight wrapper that dynamically imports the newly isolated CLI logic, ensuring thesys.pathcorrectly resolves upstream dependencies (trtmc_benchmark) in advance.Change categories
Validation
Commands and Results
```bash
Hardware, Environment, and Revisions
Not applicable: Architectural refactor isolated to local tooling layout.
Not Run / Remaining Gaps
None: Backward compatibility is retained via the wrapper proxy, and functionality logic remains identical.
Contributor Self-Review
Notes For Future Readers
Risk level
Low risk because the execution logic was lifted and shifted identically, and the entry point guarantees backward-compatible interactions for CI runner steps.
